- the box 1 for packaging a batch of articles corresponding to the preparation of an order comprises according to a first variant of the invention, a corrugated cardboard belt or the like made from four 2,3,4,5 panels, for example rectangular, arranged vertically and joined to each other by their length, the walls 2,4 and 3,5 opposite being normally, although not necessarily, identical in order to form in the space, a rectangular parallelepiped; this belt is provided in its lower part with a bottom 6 secured to any known way to each of the walls 2,3,4,5 to form a receptacle 10 open upwards.
- the receptacle 10 can be obtained from a simple American half-box or an American box without the upper flaps or even from a tray with a bottom glued for example on entablatures; of course the choice of a parallelepipedic box 1 corresponding to the vast majority of uses, is not limiting and one could perfectly conceive of producing receptacles 10 comprising more than four vertical walls to satisfy a particular need in the handling or transport.
- a flat and rigid element 11 is then forcibly inserted into the interior of the receptacle 10 provided with its heat-shrinkable film 7, the two curtains 8, 9 of which have been folded down outside the vertical walls 3, 5 so as to ply against the film 7 on the bottom 6 of the receptacle.
- the element 11 which comes to lock the film 7 at the bottom 6 of the receptacle 10 is correctly dimensioned to be inserted by force between the two vertical walls 3.5 overlapped by the two curtains 8,9, thus providing a real wedging of the film 7 respectively between the edge 12 of the element 11 and the wall 3 and between the edge 13 and the wall 5.
- the planar element 11 must be rigid to provide maximum blocking of the film 7 between the vertical walls 3,5 of the receptacle 10; advantageously this planar element 11 will be cut from corrugated cardboard, preferably, although not necessarily, to the dimensions of the bottom 6 of the receptacle 10 in order to constitute a real double bottom.
- the flat element 11 will be inserted in such a way that the direction of the grooves 14 is perpendicular to the lines of contact with the vertical walls 3, 5 between which said element 11 is force-fitted.
- FIGS. 3 and 4 a second variant of the box in accordance with the invention will now be given, observing that the parts of FIGS. 3 and 4 which are common to the two variants have the same references as in FIGS. 1 and 2.
- the receptacle 1 will advantageously be formed from four side walls 2,3,4,5, preferably of rectangular shape held together to form a belt, for example of corrugated cardboard or the like secured to a bottom 6, to form in a very usual manner, a receptacle 10 ′ such as an American box without upper flaps or an American half-box or even a tray with single walls or double walls commonly used in the field of packaging.
- a receptacle 10 ′ such as an American box without upper flaps or an American half-box or even a tray with single walls or double walls commonly used in the field of packaging.
- the planar element 11 ′ coming as in the previous variant against the central part of the film 7 on the bottom 6 of the receptacle 10 ′ naturally has all the characteristics of the planar element 11 of the first variant, but it is additionally provided with pins 15,16 extending outwards in the plane of the element 11 'from the opposite edges 12,13 of said element 11' coming into contact with two side walls 3,5 of the receptacle 10 'contributing to the blocking of the two curtains 8.9.
- the two grooves 17, 18 are arranged in the lower part of the vertical walls 3.5 just above the junction line between said walls 3.5 and the bottom 6, over a length at most equal to the length of said walls and normally over a sufficient length to firmly hold the element 11 'against the bottom 6 of the receptacle 10.
- the element 11 'snapped into the grooves 17,18 of the opposite side walls 3,5 not only against the greenhouse by its edges 12,13 the film 7 against the same vertical walls 3,5 but by the play of the two tenons 15 , 16 forms corners which irreversibly embed the base of the curtains 8, 9 in the grooves 17 and 18.
- any traction on the film 7, for example in the event of a fall, impact or rough handling, will be compensated not only by the wedging effect of the part 11 ′ as in the first variant but also by the wedge effect of the tenons 15, 16 embedded in the grooves 17, 18 of the vertical walls 3.5.
- FIG. 5 shows a parallelepipedal half-box 20 for packaging in cardboard or the like for transporting a load, said half-box comprising a lateral belt 21 formed by four vertical walls 22 and a horizontal bottom 23 formed by four flaps secured to said belt via junction lines 24, and a heat-shrinkable plastic film material 25 intended for packaging and holding the load in place (not shown).
- the half-body has a rigid rectangular plate 26 attached, flattening the heat-shrinkable film on the internal face 27 of the bottom of the body while letting escape on either side of two opposite edges facing 28 of the plate, portions 29 and 30 of curtain of free material extending from the edges 28 over a length sufficient to cover each other by completely enveloping the load and blocking said load by thermal shrinkage of the film.
- the plate 26 is inserted between at least two first opposite vertical walls so that said edges are in contact or substantially in contact via the plastic film 25 with at least part of the joining lines 24 of said first walls.
- the box comprises blocking means 31 of the plate 26 against the bottom 23.
- the blocking means 31 comprise portions of internal flaps 32 directly bonded to the internal faces 33 of the first vertical walls 22, the lower periphery 34 of the internal flaps coming into abutment with the upper edges 35 of the plate to ensure blocking, thus wedging the plastic film 25 between the lower edge of the flaps 32, the internal face of the first wall and the end of the upper face of the edge of the plate.
- the half-body is formed from a blank comprising the four rectangular walls 22 separated by vertical fold lines 36 provided with a lower rectangular flap 37 intended to form the bottom 23 , attached to the lower part of the box by a fold line 24 aligned with that of the adjacent flap.
- Two interior flaps 32 bonded to two non-adjacent walls are provided.
- They are for example rectangular and of a surface slightly less than that of the walls 22 concerned.
- the lower periphery 34 of the flaps is situated at a distance e_ corresponding to the thickness of the plate 26 which slides into abutment under said peripheries.
- FIG. 7 is a top view of FIG. 5 showing the two facing walls 22, each provided with two internal flaps 32 for blocking the plate 26 against the bottom formed by the flaps 37.
- the plastic film 25 (in phantom in the figure) is moreover pierced with circular orifices 38 of small diameter, for example four orifices arranged on a line parallel to the junction line 24, at a distance of 1 to 5 cm. of the latter, for example 2 cm.
- the holes are one or two centimeters.
- Glue dots 39 were injected through allowing direct bonding of the underside of the added plate 26 on the upper, flat face, large contiguous flaps 37 which constitute the upper part of the bottom, the small flaps being in turn folded outside and glued.
- the plastic film 25 is also glued on one or on its two sides to the adjoining cardboard faces, for example by two lines 40 of so-called "hot melt” glue.
- FIGS. 8 to 10 show another embodiment of the primary container 49 or box obtained from the blank 50.
- the box 49 is in the form of a tray comprising a rectangular bottom 51 comprising four first rectangular flaps equal in pairs 52 and 53 connected respectively to each side of the bottom by fold lines 54 perpendicular to each other.
- Two first opposite flaps 53 for example corresponding to the short sides, each comprise on either side, second rectangular flaps 55 attached to the lateral peripheries of said first flaps.
- the second flaps 55 have, in the lower part, rectangular recessed portions 56 of height equal to or substantially equal to that of the plate 57, arranged to allow the vertical blocking of the plate 57 (see FIGS. 8 and 9) previously provided on its lower face.
- a plastic sheet 58 for example secured by gluing, which comes to be embedded below the lower edges 59 of the second flaps 55 by wedging the film 58 as shown in FIG. 9.
- the film 58 thus describes a horizontal path parallel to the bottom 60 of the box, then vertical over a small lower portion 61 of the vertical wall 53, then horizontal 62 towards the inside of the box, before leaving freely towards the load and / or the top and the inside of said box, so that it can then be folded back onto the load 63 (in dashed lines in the figure) as shown with the arrows 64.
- the plate blocking means may even comprise, or be constituted by, a product to be packaged, higher than the others, which would come into abutment on the internal face of the cover (not shown) when the cover is put in place.
- Figures 11 to 13 show another embodiment of a box 70 for crate according to the invention with rectangular plate 71 provided with a plastic film 72 pre-glued on the underside of the plate.
- the film includes for example orifices or recesses 73, for example in the form of small size lunules (from 0.5 cm to 3 cm maximum size, for example 1 cm) for example two rows of 10 lunules 73 (2 times 5) staggered, that is to say offset, suitable for being arranged below and vertically in line with the internal wall sections specified below, or directly near towards the interior of the box.
- orifices or recesses 73 for example in the form of small size lunules (from 0.5 cm to 3 cm maximum size, for example 1 cm) for example two rows of 10 lunules 73 (2 times 5) staggered, that is to say offset, suitable for being arranged below and vertically in line with the internal wall sections specified below, or directly near towards the interior of the box.
- the box 70 in the form of a tray comprises four rectangular walls formed by two small flaps 74 and two large flaps 75 attached to the bottom 76 by fold or junction lines 77.
- Each small flap comprises two second rectangular lateral flaps 78, with lower recess 79 for blocking the plate against the bottom as described above.
- These recesses are substantially rectangular, of width e_ between the extension of the fold line 77 and the lower edge of the flap 78, and extend over the entire length of the second flap 78.
- the second flaps 78 are also glued to the faces internal of large flaps 75.
- the large flaps 75 comprise, on their upper horizontal periphery, third rectangular flaps 81 attached to the latter by double fold lines 82, of thickness equal to or slightly greater than that of the second flaps 78, so as to be folded down , and glued to the external faces 83 directed towards the inside of the box of the second flaps 78, as shown in FIG. 12.
- the plastic film 72 previously introduced into the tray formed or secured to the plate 71 before being introduced is thus wedged horizontally between the lower edges 84 of the second flaps 85 and of the third flaps on one more large horizontal distance, the width 1 of the third flaps being calculated to allow said flap to graze and / or also wedge the plate against the bottom on the plastic film.
- the third flaps can be folded only after introduction of the film and the plate, thus further consolidating the blocking, which will allow the transport of objects particularly heavy like kitchen utensils for example.
- FIGS 14 to 17 show another embodiment of the invention.
- the box 90 is here obtained from a blank 91 in the form of a belt provided with four rectangular flaps 92, 93, 94 and 95 forming the vertical walls of the box obtained from the box.
- a lateral bonding tab is also provided in a known manner.
- Each flap comprises a lower flap, namely the large flaps 92 and 94 each comprise a rectangular flap 96 intended to form the contiguous and flat face of the bottom against which the plate 97 will be locked, and the small flaps 93 and 95 comprise a flap identical 98 of rectangular shape higher than that of the small adjacent flap to which it is attached.
- Each flap 98 has a central tab 99 detachable from said flap, but attached by a fold line 100 offset from the junction lines 101, aligned, flaps 92 to 95, with the bottom.
- the tabs 99 for example of rectangular shape, on the other hand remain horizontal in the same plane as the other flaps 96, a complementary recess 99 ′ therefore appearing in said flaps 98.
- the box is then formed, for example around a mandrel, the large rectangular flaps 96 being above and the tabs 99 glued below said flaps 96 (see FIG. 17).
- the plate 97 provided with the film 103 for example of transverse dimension a little less than the length between raised flaps 98 to allow its introduction, is then introduced and comes to block the film 103 on the flat bottom of the box.
- the flaps 98 are folded down (arrow 104) and come to constitute the means for blocking the plate 97 on the bottom, plate with which they are glued (cf. FIG. 15), the film 103 escaping on the sides as shown on the figure.
- the film is in one piece.
- the plate is made of corrugated cardboard, the direction of the grooves of which is perpendicular to the contact lines with the first vertical walls between which said plate is inserted, and the plate completely covers the bottom of the body to constitute a double bottom.
- a first step 110 consists in forming the bottom and the vertical walls of the box which are left open on the top.
- Such training can for example be carried out around a mandrel from a flap belt as described in documents FR-A-2 629 012 or FR-A-2 665 137.
- the blocking means may in this case be either the internal blocking flaps glued to the walls, or snap-fastening means, the whole being completed by bonding through the plastic film (s).
- a composite element is formed (step 111) comprising the plate and the plastic material previously secured at least temporarily to said plate by gluing (step 112).
- the composite element is introduced into said box until it comes into locking position in abutment against the bottom of the box, maintaining if necessary the free edges of the plastic film towards outside, for example by blowing nozzles.
- step 114 we then come (step 114) to place the load in the packaging, we close (115) the ends of the plastic film on it, which is heat sealed at 116, then we perform thermal constriction (step 117) for example by passing through a tunnel heating in a manner known per se.
- the packaging is then closed (step 118) by placing the cover and / or simply closing it with gluing if it is upper flaps, before removing (119) the packaging.
- Another method consists in introducing the plastic film before introducing the plate.
- the composite element is placed on the bottom of the mandrel and then the body is formed on top.

5 La présente invention concerne un emballage du type caisse en carton munie d'un film rétractable qui lui est solidaire, destiné au conditionnement d'articles destinés à être délivrés en nombre ou en volume très variable .The present invention relates to a packaging of the cardboard box type provided with a shrink film which is integral with it, intended for the packaging of articles intended to be delivered in number or in very variable volume.
10 Elle concerne également un procédé et un dispositif de formation d'un emballage de conditionnement du type caisse en carton munie d'un film rétractable.It also relates to a method and a device for forming a packaging package of the cardboard box type provided with a shrink film.

25 généralement le commerce de détail.25 usually retail.
On comprend bien que les grossistes, pour préparer la commande de leurs détaillants, aient besoin de conditionner des lots d'articles par nature très différents dans des emballages qui doivent néanmoins
supporter des conditions de transport et de livraison parfois difficiles ; compte tenu du coût des caisses standard, il est vite apparu difficile d'utiliser de tels emballages pour conditionner des lots d'articles de cette nature, car ceci supposerait de recourir systématiquement à des gammes d'emballages dont le stockage serait extrêmement coûteux et par conséquent inadapté à cette forme de distribution.It is easy to understand that wholesalers, in order to prepare the order for their retailers, need to package lots of very different articles by nature in packaging which must nevertheless withstand sometimes difficult transport and delivery conditions; given the cost of standard boxes, it quickly became difficult to use such packaging to package batches of items of this nature, as this would imply systematically using ranges of packaging whose storage would be extremely expensive and therefore unsuitable for this form of distribution.
On connaît déjà de nombreuses solutions à ce type de problèmes qui ont depuis longtemps proposé de conditionner les lots d'articles à l'intérieur d'une caisse ou d'une barquette notamment en carton, recouverte par une feuille de plastique thermorétractable liée à la face interne du fond de la caisse et/ou à la face interne des deux parois verticales opposées ; de cette manière, il suffit de disposer à l'intérieur d'un fond en carton les objets à emballer, de les recouvrir ensuite par la feuille plastique que l'on viendra enfin totalement rétracter sur les produits par passage dans un tunnel chauffant par exemple, avec comme conséquence de maintenir lesdits produits bien arrimés à la caisse de transport. De telles solutions sont normalement très avantageuses puisqu'elles ne nécessitent qu'une seule caisse d'un volume de carton minimum procurant de substantielles économies de matières en plus d'évidentes économies de stockage d'emballage devenu unique .
Dans ce sens on connaît le brevet français FR- 2.426.620 selon lequel on utilise pour emballer un lot de produits, deux feuilles plastiques qui se chevauchent par l'une de leurs extrémités au dessus de la charge afin d'y être soudé à chaud au niveau de la zone de chevauchement, l'autre de leurs extrémités qui n'est pas en contact avec la charge étant collée à la face interne du fond ou à proximité du fond sur la face interne d'une paroi latérale d'une caisse carton obtenue à partir d'un simple flan formant le fond de la caisse à partir duquel s'étendent deux faces latérales venant préalablement se rabattre sur la charge avant de rabattre les deux feuilles plastiques qui viendront par soudure maintenir l'ensemble. Cet emballage particulier souffre d'un grave défaut de tenue mécanique de 1 ' ensemble ; en effet, tout le conditionnement est lié à la résistance au décollage ou à l'arrachage des liaisons des feuilles plastiques avec le fond ou les parois latérales de la caisse carton. On sait bien que de tels emballages sont soumis à de fortes sollicitations à l'occasion de la manutention et du transport conduisant fréquemment à la rupture des liaisons des films plastiques avec la base carton. A cet égard d'autres solutions ont été proposées se fondant cette fois sur l'observation surprenante que la résistance au décollage ou à l'arrachage des matériaux thermo-rétractables en feuille au cours des opérations de manutention et/ou de transport était
améliorée quand la liaison desdits matériaux thermorétractables à la caisse était réalisée à 1 ' extérieur de ladite caisse sur au moins une face externe (fond ou paroi latérale) de celle-ci, le chant de ladite face, qui est recouvert par ledit matériau thermorétractable en feuille, intervenant comme moyen s ' opposant aux contraintes exercées par le poids de la charge .Numerous solutions to this type of problem are already known, which have long proposed to package batches of articles inside a box or a container, in particular of cardboard, covered by a sheet of heat-shrinkable plastic linked to the internal face of the bottom of the body and / or the internal face of the two opposite vertical walls; in this way, it suffices to place the objects to be packaged inside a cardboard bottom, then cover them with the plastic sheet which will finally be completely shrunk on the products by passing through a heating tunnel for example , with the consequence of keeping said products securely stowed at the transport crate. Such solutions are normally very advantageous since they require only a single case of a minimum volume of cardboard providing substantial savings in materials in addition to obvious savings in packaging storage which has become unique. In this sense we know the French patent FR-2,426,620 according to which we use to pack a batch of products, two plastic sheets which overlap by one of their ends above the load in order to be welded hot at the level of the overlap zone, the other of their ends which is not in contact with the load being glued to the internal face of the bottom or close to the bottom on the internal face of a side wall of a box cardboard obtained from a simple blank forming the bottom of the box from which extend two side faces which are previously folded over the load before folding the two plastic sheets which will come by welding to maintain the assembly. This particular packaging suffers from a serious mechanical failure of the assembly; indeed, all the packaging is linked to the resistance to take-off or tearing of the connections of the plastic sheets with the bottom or the side walls of the cardboard box. It is well known that such packaging is subjected to high stresses during handling and transport frequently leading to the rupture of the connections of the plastic films with the cardboard base. In this respect, other solutions have been proposed, this time based on the surprising observation that the resistance to peeling or tearing off of the heat-shrinkable sheet materials during handling and / or transport operations was improved when the connection of said heat-shrinkable materials to the body was carried out outside of said body on at least one external face (bottom or side wall) thereof, the edge of said face, which is covered by said heat-shrinkable material sheet, acting as a means opposing the stresses exerted by the weight of the load.
Dans ce sens, plusieurs solutions ont déjà été proposées, notamment dans le brevet français FR-A- 86.01435 décrivant une caisse de conditionnement constituée d'un étui par exemple en carton et d'un matériau thermo-rétractable en feuille pour l'emballage et le maintien en place d'une charge caractérisé en ce que le matériau thermo-rétractable en feuille est lié par au moins une de ses bordures à la surface externe d'une paroi de l'étui au voisinage du chant de ladite paroi, et est développée à l'extérieur à partir de ladite bordure vers le chant de ladite paroi puis à l'intérieur de l'étui en regard de la surface interne de ladite paroi tout en s 'éloignant de celle-ci vers la charge à emballer. On retrouve d'ailleurs une solution analogue dans le brevet français FR-A-85.16217 selon lequel les feuilles thermo-rétractables sont insérées entre les faces internes des parois et des portions de ces mêmes parois repliées vers l'intérieur de la caisse.In this sense, several solutions have already been proposed, in particular in French patent FR-A-86.01435 describing a packaging case consisting of a case, for example made of cardboard and of a heat-shrinkable sheet material for packaging and holding a load in place, characterized in that the heat-shrinkable sheet material is linked by at least one of its edges to the external surface of a wall of the case in the vicinity of the edge of said wall, and is developed outside from said edge towards the edge of said wall and then inside the case opposite the internal surface of said wall while moving away from it towards the load to be packaged. A similar solution is also found in French patent FR-A-85.16217 according to which the heat-shrinkable sheets are inserted between the internal faces of the walls and portions of these same walls folded towards the inside of the box.
Ces dernières solutions ont pour inconvénient soit de nécessiter une coiffe dans le premier cas, soit de
prévoir à l'origine une découpe spéciale coûteuse en matière et générant un surcoût dans la gestion de stock de tels emballages ; en outre, ces solutions sont mécaniquement plus compliquées dans la mesure où elles nécessitent deux feuilles de plastique compliquant sensiblement les opérations de montage.The latter solutions have the drawback either of requiring a cover in the first case, or of originally provide for a special cutting costly in material and generating an additional cost in the stock management of such packaging; in addition, these solutions are mechanically more complicated insofar as they require two sheets of plastic significantly complicating the mounting operations.
Une autre solution a été proposée dans le brevet français FR-2.577.001 qui décrit une caisse américaine ou similaire utilisant un film en matière plastique thermo-rétractable solidaire du fond de la caisse caractérisé en ce que le film en matière plastique est pincé entre les rabats externes attenants à deux parois parallèles de la caisse et constituant le fond proprement dit de l'emballage, et les rabats internes, attenants aux deux autres parois et doublant le fond intérieurement .Another solution has been proposed in French patent FR-2,577,001 which describes an American box or the like using a heat-shrinkable plastic film secured to the bottom of the box, characterized in that the plastic film is pinched between the external flaps adjoining two parallel walls of the box and constituting the bottom proper of the packaging, and the internal flaps, adjoining the other two walls and lining the bottom internally.
Cette dernière solution a l'avantage de pouvoir être mécanisée relativement facilement puisque le film thermo-rétractable peut être inséré de manière continue à partir d'une bobine et en outre la solution ne nécessite aucun collage dudit film au fond de la caisse, palliant ainsi les inconvénients précités .The latter solution has the advantage of being able to be mechanized relatively easily since the heat-shrinkable film can be inserted continuously from a reel and furthermore the solution does not require any bonding of said film to the bottom of the box, thus overcoming the aforementioned drawbacks.
En revanche, cette dernière solution n'est pas satisfaisante puisqu'elle n'est adaptable qu'à des caisses américaines à fond complet, excluant par exemple des caisses à rabats réduits mais également les barquettes à coins collés extérieurs ou intérieurs ou encore les caisses américaines
jonctionnées dont la fermeture est assurée par un couvercle collé indépendant .On the other hand, the latter solution is not satisfactory since it is only adaptable to American boxes with full bottoms, excluding for example boxes with reduced flaps but also trays with glued corners outside or inside or even boxes american joined together, closed by an independent bonded cover.
On connaît également (FR-A-2.661.392) un procédé pour le conditionnement des lots de produits de volumes divers dans lequel on pistonne une cale dans une caisse en entraînant un film plastique. Le film est disposé et dépasse transversalement de part et d'autre de la cale qui est moins large que la dimension interne de la caisse dans le sens transversal, et qui comporte longitudinalement sur ses deux côtés opposés deux ailes ou rabats élastiques verrouillés par effet ressort via des languettes de verrouillage dans des ouvertures complémentaires des parois de la caisse préalablement formée .There is also known (FR-A-2,661,392) a process for the packaging of batches of products of various volumes in which a piston is pressed into a box by entraining a plastic film. The film is arranged and protrudes transversely on either side of the wedge which is narrower than the internal dimension of the body in the transverse direction, and which has longitudinally on its two opposite sides two wings or elastic flaps locked by spring effect via locking tabs in openings complementary to the walls of the previously formed box.
Un tel procédé ne permet pas d'obtenir un emballage susceptible de maintenir des objets de poids important .Such a method does not make it possible to obtain a packaging capable of holding objects of significant weight.
On connaît aussi (DE 81.15.943) une caisse d'emballage pour petites pièces de formes quelconques, munie d'une gaine ou sac en matière plastique thermorétractable et d'une ou plusieurs palettes superposées s' introduisant avec ajustement dans la gaine et la caisse. Ici encore un tel emballage présente des inconvénients. Sa fabrication n'est pas mécanisable compte tenu notamment de la difficulté d' introduire la palette dans la gaine ou le sac, et il ne peut concerner que de petits objets (vis par exemple) .
Pour palier à tous ces inconvénients la présente invention propose notamment une caisse de conditionnement en carton ou analogue pour le transport d'une charge, ladite caisse comprenant une ceinture latérale formée d'au moins quatre parois verticales et d'un fond horizontal solidarisé avec ladite ceinture via des lignes de jonction, un matériau plastique thermo-rétractable en film destiné à l'emballage et au maintien en place de ladite charge, au moins une plaque rapportée, plaquant le film thermo-rétractable sur la face interne du fond de la caisse en laissant s'échapper de part et d'autre de deux bords opposés en vis à vis de ladite plaque, dits bords transversaux, des portions de rideau de matière libre s ' étendant depuis lesdits bords transversaux sur une longueur suffisante pour se recouvrir l'une l'autre en enveloppant totalement la charge et bloquer ladite charge par rétraction thermique du film et des moyens de blocage de ladite plaque contre le fond, caractérisé en ce que la plaque est rigide et en ce que elle est insérée entre au moins deux premières parois verticales opposées de sorte que lesdits bords transversaux soient en contact via le film en matériau plastique avec au moins une partie des lignes de jonction desdites premières parois.
Autrement dit la distance qui sépare les bords transversaux de la plaque est sur au moins une partie desdits bords, supérieure ou égale aux dimensions transversales intérieures de la caisse. Avantageusement la plaque rigide est une plaque plane quand elle est à plat et dénuée de rabats, c'est à dire dont les portions périphériques latérales, transversales et longitudinales, ne sont pas reliées par des lignes de pliage ou rainage avec la partie centrale de la plaque, par exemple pour former des ailes se déformant élastiquement lors d'une introduction dans la caisse.There is also known (DE 81.15.943) a packaging case for small parts of any shape, provided with a sheath or bag of heat-shrinkable plastic and one or more superimposed pallets being introduced with adjustment in the sheath and the checkout. Here again, such packaging has drawbacks. Its manufacture cannot be mechanized, in particular given the difficulty of introducing the pallet into the sheath or the bag, and it can only concern small objects (screws for example). To overcome all these drawbacks, the present invention proposes in particular a cardboard packaging box or the like for transporting a load, said box comprising a lateral belt formed by at least four vertical walls and a horizontal bottom secured to said belt via junction lines, a heat-shrinkable plastic film material intended for the packaging and holding in place of said load, at least one attached plate, pressing the heat-shrinkable film on the internal face of the bottom of the box by letting escape on either side of two opposite edges opposite said plate, called transverse edges, curtain portions of free material extending from said transverse edges over a length sufficient to cover the the other by completely enveloping the load and blocking said load by thermal shrinkage of the film and means for locking said plate against the bottom, char laughed in that the plate is rigid and in that it is inserted between at least two first opposite vertical walls so that said transverse edges are in contact via the plastic film with at least part of the junction lines of said first walls . In other words, the distance which separates the transverse edges of the plate is on at least part of said edges, greater than or equal to the internal transverse dimensions of the box. Advantageously, the rigid plate is a flat plate when it is flat and devoid of flaps, that is to say the lateral, transverse and longitudinal peripheral portions of which are not connected by fold or crease lines with the central part of the plate, for example to form wings elastically deforming during an introduction into the body.
Autrement dit, la plaque a une dimension transversale égale ou supérieure aux dimensions transversales intérieures de la boîte, c'est à dire que la distance qui sépare les bords transversaux en contact et contournés par le film en matière plastique est au moins égale aux dimensions transversales intérieures de la caisse. Par dimensions transversales intérieures de la caisse on entend la plus petite distance séparant les faces internes de deux parois opposées dans le sens transversal .In other words, the plate has a transverse dimension equal to or greater than the internal transverse dimensions of the box, that is to say that the distance which separates the transverse edges in contact and circumvented by the plastic film is at least equal to the transverse dimensions inside the box. By internal transverse dimensions of the body is meant the smallest distance separating the internal faces of two opposite walls in the transverse direction.
On comprend bien qu'une telle solution présente de nombreux avantages par rapport à tous les enseignements antérieurs dans la mesure où il est possible d'équiper n'importe quels cartons, caisses, barquettes ou étuis formant réceptacle d'un film thermo-rétractable destiné à envelopper une charge
quelconque sans risquer les problèmes de décollement ou d'arrachage lors des manutentions ou des chocs à l'occasion des transports ; de même la solution préconisée par l'invention s'accommode aussi bien d'une fabrication en continu dans la mesure où l'on utilise un film rétractable d'un seul tenant ou d'une fabrication tout à fait manuelle et ponctuelle puisqu'il suffit de prévoir, outre une bobine de film thermo-rétractable, des éléments plans que l'on découpe au moment venu aux dimensions du fond de la barquette, de la caisse ou de tout autre contenant en carton ondulé compact ou autre matériau en feuilles, le montage du film et de la plaque se faisant simplement par insertion à force ou en biais ou à tout le moins en contact entre deux parois latérales opposées du contenant à équiper.It is well understood that such a solution has many advantages over all previous teachings insofar as it is possible to equip any cardboard boxes, cases, trays or cases forming a receptacle with a heat-shrinkable film intended to wrap a load any without risking the problems of detachment or tearing off during handling or impact during transport; similarly, the solution recommended by the invention is equally suitable for continuous manufacturing insofar as one uses a shrink film in one piece or a completely manual and punctual manufacturing since It suffices to provide, in addition to a reel of heat-shrinkable film, planar elements which are cut when the time comes to the dimensions of the bottom of the tray, the case or any other container made of compact corrugated cardboard or other sheet material, the mounting of the film and the plate is done simply by force or bias insertion or at least in contact between two opposite side walls of the container to be fitted.
Bien entendu et selon une autre caractéristique importante de l'invention, l'élément plan constituant le double fond du contenant est obtenu à partir d'un simple flan de carton ondulé dont il convient simplement de bien orienter les sens des cannelures comme il sera expliqué plus loin.Of course, and according to another important characteristic of the invention, the planar element constituting the double bottom of the container is obtained from a simple blank of corrugated cardboard, the directions of the grooves of which must simply be oriented as will be explained. further.
Dans des modes de réalisation avantageux on a de plus recours à l'une et/ou à l'autre des dispositions suivantes:In advantageous embodiments, one and / or the other of the following arrangements are also used:
- pour constituer au moins en partie les moyens de blocage, la face inférieure de la plaque est au moins en partie directement collée à la face supérieure du
fond de la caisse, au travers d'au moins un évidemment du film ou sur une surface dénuée de film. Avantageusement, la face supérieure de la caisse est collée avec la face inférieure de la plaque au travers de plusieurs petits évidements.- to constitute at least partially the locking means, the lower face of the plate is at least partly directly bonded to the upper face of the bottom of the box, through at least one recess of the film or on a surface devoid of film. Advantageously, the upper face of the box is glued with the lower face of the plate through several small recesses.
Egalement avantageusement les faces sont collées au travers d'un large orifice central du film en vis à vis du centre de la plaque, par exemple circulaire ou ovale, de cinq à dix centimètres de dimension transversale maximale.Also advantageously the faces are glued through a large central orifice of the film opposite the center of the plate, for example circular or oval, from five to ten centimeters in maximum transverse dimension.
Pour constituer les évidements le film est également par exemple ajouré sous forme de plusieurs orifices percés par chauffage ou poinçonnage, par exemple en forme de lunules, disposés à proximité des lignes de jonction, par exemple à un ou deux centimètres desdites lignes de jonction des premières parois, le collage carton sur carton s' effectuant au travers des orifices, un collage complémentaire du film en matériau plastique pouvant également s'effectuer par débordement de la colle sous et sur les périphéries des orifices;To constitute the recesses, the film is also, for example, perforated in the form of several orifices drilled by heating or punching, for example in the form of lunules, arranged near the junction lines, for example one or two centimeters from said junction lines of the first walls, the cardboard to cardboard bonding being carried out through the orifices, a complementary bonding of the film of plastic material can also be carried out by overflowing of the adhesive under and on the peripheries of the orifices;
- les moyens de blocage sont constitués au moins en partie par les premières parois, la plaque étant de dimension un peu supérieure à la distance entre lesdites premières parois de sorte que ladite plaque est coincée en force entre lesdites premières parois après insertion;- The locking means are constituted at least in part by the first walls, the plate being of dimension slightly greater than the distance between said first walls so that said plate is jammed in force between said first walls after insertion;
- pour constituer au moins en partie les moyens de blocage, la plaque comporte sur au moins un de ses
deux bords opposés, au moins un tenon, ledit tenon collaborant avec un évidement correspondant réalisé au niveau de la ligne de jonction avec le fond de la première paroi en vis à vis, pour procurer 1 ' encliquetage de la plaque une fois cette dernière en place contre le fond de la caisse;- To constitute at least partially the locking means, the plate has on at least one of its two opposite edges, at least one lug, said lug collaborating with a corresponding recess made at the level of the junction line with the bottom of the first facing wall, to provide the snap-fitting of the plate once the latter in place against the bottom of the body;
1 ' évidement est constitué par une rainure de hauteur égale ou sensiblement égale à l'épaisseur de ladite plaque et s ' étendant sur une partie de la longueur de ladite ligne de jonction;1 recess is constituted by a groove of height equal or substantially equal to the thickness of said plate and extending over a portion of the length of said junction line;
- les moyens de blocage comportent des portions de volets intérieurs directement collés sur les faces internes desdites premières parois verticales, la périphérie inférieure desdits volets intérieurs venant en butée avec les bords supérieurs de la plaque pour assurer ledit blocage; les moyens de blocage comportent des rabats rattachés aux périphéries supérieures des premières parois par des lignes de pliage; - les moyens de blocage comportent des rabats rattachés aux périphéries latérales des secondes parois directement ou indirectement adjacentes aux premières parois .- The locking means comprise portions of interior flaps directly bonded to the internal faces of said first vertical walls, the lower periphery of said interior flaps abutting with the upper edges of the plate to ensure said locking; the locking means comprise flaps attached to the upper peripheries of the first walls by fold lines; - The locking means comprise flaps attached to the lateral peripheries of the second walls directly or indirectly adjacent to the first walls.
Par indirectement adjacente il faut entendre une paroi qui serait par exemple séparée de la première paroi par un coin coupé; les moyens de blocage comportent des rabats rattachés aux périphéries inférieures des première parois par des lignes de pliage formant au moins en
partie les lignes de jonction avec le fond, lesdits rabats comportant chacun une languette détachable dudit rabat mais restant attachée auxdites lignes de jonction et fixée sur le fond de la caisse formée par deux autres rabats, lesdits rabats étant rabattus et par exemple fixés par collage par dessus la plaque;By indirectly adjacent is meant a wall which would for example be separated from the first wall by a cut corner; the locking means comprise flaps attached to the lower peripheries of the first walls by fold lines forming at least in part of the junction lines with the bottom, said flaps each comprising a tab detachable from said flap but remaining attached to said junction lines and fixed to the bottom of the body formed by two other flaps, said flaps being folded down and for example fixed by gluing by above the plate;
- le film en matériau thermo-rétractable est d'un seul tenant;- the film of heat-shrinkable material is in one piece;
- la plaque est en carton ondulé dont le sens des cannelures est perpendiculaire aux lignes de contact avec les premières parois verticales entre lesquelles ladite plaque est insérée; la plaque recouvre totalement le fond de la caisse pour constituer un double fond; - la caisse est réalisée à partir d'un flan comportant une suite de volets terminée par une languette de fixation, reliés les uns aux autres par des premières lignes de pliage parallèles les unes aux autres, et un premier ensemble de rabats latéraux disposés d'un côté et reliés aux volets principaux par des deuxièmes lignes de pliage formant lesdites lignes de jonction, perpendiculaires aux premières lignes de pliage et destinés à former au moins partiellement le fond de la caisse, lesdites deuxièmes lignes de pliage étant alignées et ladite caisse étant agencée pour être montée automatiquement par rabattement desdits volets et des rabats dudit premier ensemble autour d'un mandrin, le volet d'extrémité de la suite de volets et la
languette d'une part, et les rabats adjacents d'autre part, étant fixés entre eux par collage pour former ladite caisse;- The plate is made of corrugated cardboard, the direction of the grooves is perpendicular to the contact lines with the first vertical walls between which said plate is inserted; the plate completely covers the bottom of the box to form a double bottom; - The box is made from a blank comprising a series of flaps terminated by a fixing tab, connected to each other by first fold lines parallel to each other, and a first set of lateral flaps arranged in one side and connected to the main flaps by second fold lines forming said junction lines, perpendicular to the first fold lines and intended to form at least partially the bottom of the box, said second fold lines being aligned and said box being arranged to be mounted automatically by folding down said flaps and flaps of said first set around a mandrel, the end flap of the series of flaps and the tongue on the one hand, and the adjacent flaps on the other hand, being fixed together by gluing to form said box;
- la suite comporte huit volets, à savoir quatre volets principaux séparés deux à deux par quatre volets intermédiaires.- the suite has eight components, namely four main components separated two by two by four intermediate components.
Il va de soi que les modes de réalisation plus particulièrement décrits ici qui sont des demi caisses, sont prévus pour constituer des caisses selon l'invention et comportent pour ce faire des couvercles connus en eux même, par exemple constitués par des rabats reliés aux parois par des lignes de pliage ou par un couvercle rapporté en forme de plaque reliée ou non par une ligne de pliage à une paroi .It goes without saying that the embodiments more particularly described here which are half cases, are provided to constitute cases according to the invention and to do this include covers known in themselves, for example constituted by flaps connected to the walls by fold lines or by a cover in the form of a plate connected or not by a fold line to a wall.
L'invention propose également un procédé de formation d'une caisse de conditionnement en carton ou analogue pour le transport d'une charge, telle que décrite ci-dessus. Avantageusement le procédé comporte les étapes suivantes : on forme le fond et les parois verticales de la caisse qu'on laisse ouverte sur le dessus, on forme un élément composite comprenant la plaque et le matériau plastique solidarisé ou non au moins provisoirement à la dite plaque et on introduit en force ou en biais 1 ' élément composite jusqu'à venir en position de blocage en butée contre le fond de la caisse avant de refermer
le dessus de ladite caisse par pliage de rabat ou mise en place d'un couvercle, après introduction de la charge et thermoscellage .The invention also provides a method of forming a cardboard packaging box or the like for transporting a load, as described above. Advantageously, the method comprises the following stages: the bottom and the vertical walls of the box are formed which are left open on top, a composite element is formed comprising the plate and the plastic material which is at least temporarily attached to said plate and the composite element is introduced by force or at an angle until it comes to the locking position in abutment against the bottom of the body before closing the top of said box by folding a flap or fitting a cover, after introduction of the load and heat sealing.
Dans un autre mode de réalisation avantageux le procédé comporte les étapes suivantes : on forme le fond et les parois verticales de la caisse qu'on laisse ouverte sur le dessus, puis on introduit le film en matériau plastique et la plaque en force ou en biais sur le matériau plastique jusqu'à venir en position de blocage en butée contre le fond de la caisse avant de finir de former l'emballage comme décrit ci-avant.In another advantageous embodiment, the method comprises the following stages: the bottom and the vertical walls of the box are formed which are left open on top, then the plastic film and the plate are introduced by force or bias on the plastic material until it comes to the locking position in abutment against the bottom of the box before finishing forming the packaging as described above.
Avantageusement, le film ayant été préalablement perforé pour former plusieurs orifices par exemple alignés ou en quinconce parallèlement et sensiblement à proximité des bords de la plaque propres à être en vis à vis des lignes de jonction du fond avec les premières parois, on injecte de la colle au travers de ces orifices sur le carton de la plaque ou du fond situé en dessous, avant de plaquer le matériau plastique sur la plaque ou le fond et d'introduire dans la caisse ledit élément composite formé par la plaque et le film accolé, ou la plaque seule si le film est déjà introduit et plaqué sur le fond. Dans un mode de réalisation avantageux on forme le fond et les parois de la caisse autour d'un mandrin.Advantageously, the film having been previously perforated to form several orifices, for example aligned or staggered parallel and substantially close to the edges of the plate suitable for facing the lines of junction of the bottom with the first walls, sticks through these holes on the cardboard of the plate or the bottom located below, before pressing the plastic material on the plate or the bottom and introducing into the box said composite element formed by the plate and the attached film, or the plate alone if the film is already introduced and plated on the bottom. In an advantageous embodiment, the bottom and the walls of the box are formed around a mandrel.
Avantageusement avant de former le fond et les parois de la caisse, on plaque l'élément composite
sur le fond du mandrin et on forme ensuite la caisse par dessus.Advantageously before forming the bottom and the walls of the box, the composite element is plated on the bottom of the mandrel and then form the box on top.
Dans un autre mode de réalisation, on forme le fond et une partie des parois verticales de la caisse qu'on laisse ouverte sur le côté, on forme un élément composite comprenant la plaque et le matériau plastique solidarisé au moins provisoirement à la dite plaque et on introduit l'élément composite dans ladite caisse par le côté, avant de refermer ledit côté.In another embodiment, the bottom and part of the vertical walls of the box are formed, which are left open on the side, a composite element is formed comprising the plate and the plastic material secured at least temporarily to said plate and the composite element is introduced into said box from the side, before closing said side.
L'invention propose également un dispositif de fabrication d'une caisse de conditionnement en carton ou analogue pour le transport d'une charge, ladite caisse comprenant une ceinture latérale formée d'au moins quatre parois verticales et d'un fond horizontal solidarisé avec ladite ceinture via des lignes de jonction, et un matériau plastique thermorétractable en film destiné à l'emballage et au maintien en place de ladite charge, caractérisée en ce qu'il comprend des moyens de formation du fond et des parois verticales de la caisse, des moyens de présentation d'un élément composite comprenant une plaque superposée au matériau plastique, solidarisé ou non au moins provisoirement à la dite plaque et des moyens d'introduction en force, à léger frottement, ou en biais, de l'élément composite dans ladite caisse, jusqu'à plaquer le film thermo-
rétractable sur la face interne du fond de la caisse, en sandwich avec ladite plaque, en laissant s'échapper de part et d'autre de deux bords opposés en vis-à-vis de la plaque, deux portions de rideau de matière libre s ' étendant depuis lesdits bords sur une longueur suffisante pour se recouvrir l'une l'autre en enveloppant totalement une charge à introduire, des moyens de blocage de ladite charge par thermosoudage et rétraction thermique du film, lesdits moyens étant propres à plaquer ledit élément en appuyant sur la plaque rigide rapportée, et des moyens de fermeture du dessus de la caisse.The invention also provides a device for manufacturing a cardboard or similar packaging case for transporting a load, said case comprising a lateral belt formed by at least four vertical walls and a horizontal bottom secured to said belt via junction lines, and a heat-shrinkable plastic film material intended for the packaging and holding in place of said load, characterized in that it comprises means for forming the bottom and vertical walls of the body, means for presenting a composite element comprising a plate superimposed on the plastic material, secured or not at least provisionally to said plate and means for force, slight friction, or biased introduction of the composite element into said body, until pressing the thermo-film retractable on the internal face of the bottom of the body, sandwiched with said plate, letting escape on either side of two opposite edges opposite the plate, two curtain portions of free material s 'extending from said edges over a length sufficient to cover each other by completely enveloping a load to be introduced, means for blocking said load by heat sealing and thermal shrinkage of the film, said means being suitable for pressing said element in pressing on the attached rigid plate, and means for closing the top of the box.
La plaque et la demi-caisse sont ainsi agencées pour que la plaque soit insérée entre au moins deux premières parois verticales opposées de sorte que deux bords de la plaque soient en contact via le film en matériau plastique avec au moins une partie des lignes de jonction desdites premières parois puis maintenue en position de blocage de la plaque contre le fond.The plate and the half-body are thus arranged so that the plate is inserted between at least two first opposite vertical walls so that two edges of the plate are in contact via the plastic film with at least part of the junction lines. of said first walls and then held in the locking position of the plate against the bottom.
Avantageusement le dispositif comporte des moyens de collage autorisant un collage direct entre une partie de la face inférieure de la plaque et de la face supérieure du fond de la caisse en traversant le film.Advantageously, the device comprises bonding means allowing direct bonding between a part of the lower face of the plate and the upper face of the bottom of the box while crossing the film.
Dans un mode de réalisation avantageux, le dispositif comporte des moyens de formation du fond et des parois de la caisse autour d'un mandrin.
Egalement avantageusement il comporte des moyens de plaquage de l'élément composite sur le fond du mandrin .In an advantageous embodiment, the device comprises means for forming the bottom and the walls of the box around a mandrel. Also advantageously it comprises means for plating the composite element on the bottom of the mandrel.

Conformément aux figures 1 et 2 , la caisse 1 pour le conditionnement d'un lot d'articles correspondant à la préparation d'une commande comprend selon une première variante de l'invention, une ceinture de carton ondulé ou analogue constituée à partir de quatre panneaux 2,3,4,5, par exemple rectangulaires, disposés verticalement et solidarisés les uns aux autres par leur longueur, les parois 2,4 et 3,5 en regard étant normalement, quoique non nécessairement, identiques afin de former dans l'espace, un parallélépipède rectangle ; cette ceinture est munie en sa partie inférieure d'un fond 6 solidarisé de
toutes manières connues à chacune des parois 2,3,4,5 pour former un réceptacle 10 ouvert vers le haut. Il est bien évident que le réceptacle 10 peut être obtenu à partir d'une simple demi-caisse américaine ou d'une caisse américaine sans les rabats supérieurs ou encore à partir d'une barquette à fond collé par exemple sur des entablements ; bien entendu le choix d'une caisse parallélépipédique 1 correspondant à l'immense majorité des utilisations, n'est pas limitatif et on pourrait tout à fait concevoir de réaliser des réceptacles 10 comportant plus de quatre parois verticales pour satisfaire à un besoin particulier dans le domaine de la manutention ou du transport . A l'intérieur du réceptacle 10 on dispose d'abord une feuille de plastique thermo-rétractable 7 de dimension telle qu'elle recouvre sensiblement le fond 6 dudit réceptacle tout en s ' épanouissant le long de deux parois verticales opposées 3,5 pour déborder largement en dehors de la caisse 1 et former deux rideaux 8,9 qui viendront une fois la charge déposée dans le réceptacle 10 recouvrir les objets avec un recouvrement minimum entre les deux rideaux 8 , 9 pour procurer une soudure étanche après passage dans un tunnel chauffant tel qu'il sera dit plus loin.According to Figures 1 and 2, the box 1 for packaging a batch of articles corresponding to the preparation of an order comprises according to a first variant of the invention, a corrugated cardboard belt or the like made from four 2,3,4,5 panels, for example rectangular, arranged vertically and joined to each other by their length, the walls 2,4 and 3,5 opposite being normally, although not necessarily, identical in order to form in the space, a rectangular parallelepiped; this belt is provided in its lower part with a bottom 6 secured to any known way to each of the walls 2,3,4,5 to form a receptacle 10 open upwards. It is obvious that the receptacle 10 can be obtained from a simple American half-box or an American box without the upper flaps or even from a tray with a bottom glued for example on entablatures; of course the choice of a parallelepipedic box 1 corresponding to the vast majority of uses, is not limiting and one could perfectly conceive of producing receptacles 10 comprising more than four vertical walls to satisfy a particular need in the handling or transport. Inside the receptacle 10, there is first of all a sheet of heat-shrinkable plastic 7 of dimension such that it substantially covers the bottom 6 of said receptacle while flourishing along two opposite vertical walls 3,5 to overflow largely outside the body 1 and form two curtains 8,9 which will come once the load deposited in the receptacle 10 cover the objects with a minimum overlap between the two curtains 8, 9 to provide a tight seal after passing through a heating tunnel as will be said later.
Un élément plat et rigide 11 est ensuite inséré à force à 1 ' intérieur du réceptacle 10 muni de son film thermo-rétractable 7 dont les deux rideaux 8,9 ont été rabattus à 1 ' extérieur des parois verticales 3 , 5
de façon à venir contre-plaquer le film 7 sur le fond 6 du réceptacle. Bien entendu, l'élément 11 qui vient verrouiller le film 7 au fond 6 du réceptacle 10 est correctement dimensionné pour être inséré à force entre les deux parois verticales 3,5 chevauchées par les deux rideaux 8,9, procurant ainsi un véritable coincement du film 7 respectivement entre le chant 12 de l'élément 11 et la paroi 3 et entre le chant 13 et la paroi 5. On comprend facilement qu'un tel montage, particulièrement aisé à réaliser soit une solution efficace pour l'emballage d'un lot d'articles à volume indéterminé qu'il suffit de disposer sur la face supérieure de l'élément 11 et de recouvrir par les deux rideaux de matière plastique 8,9 pour obtenir un conditionnement solide et étanche après thermo-rétractation en tunnel, chauffant par exemple du film 7 et des deux rideaux 8,9 disposés en léger recouvrement . Selon une variante d'exécution de la caisse conforme à l'invention, il est tout à fait possible de procéder complémentairement à un collage de l'élément 11 sur le fond 6 du réceptacle 10, collage qui se fera en traversant le film 7. Selon une caractéristique générale de l'invention l'élément plan 11 doit être rigide pour procurer un blocage maximum du film 7 entre les parois verticales 3,5 du réceptacle 10 ; avantageusement cet élément plan 11 sera découpé dans du carton ondulé,
préférentiellement quoique non obligatoirement, aux dimensions du fond 6 du réceptacle 10 afin de constituer un véritable double fond. Pour procurer la rigidité nécessaire au carton ondulé, l'élément plan 11 sera inséré de telle manière que le sens des cannelures 14 soit perpendiculaire aux lignes de contact avec les parois verticales 3, 5 entre lesquelles ledit élément 11 est inséré à force.A flat and rigid element 11 is then forcibly inserted into the interior of the receptacle 10 provided with its heat-shrinkable film 7, the two curtains 8, 9 of which have been folded down outside the vertical walls 3, 5 so as to ply against the film 7 on the bottom 6 of the receptacle. Of course, the element 11 which comes to lock the film 7 at the bottom 6 of the receptacle 10 is correctly dimensioned to be inserted by force between the two vertical walls 3.5 overlapped by the two curtains 8,9, thus providing a real wedging of the film 7 respectively between the edge 12 of the element 11 and the wall 3 and between the edge 13 and the wall 5. It is easy to understand that such an assembly, particularly easy to produce, is an effective solution for packaging a batch of articles of undetermined volume which it suffices to have on the upper face of the element 11 and to cover with the two curtains of plastic material 8.9 to obtain a solid and waterproof packaging after heat-shrinking in the tunnel, heating for example film 7 and two curtains 8,9 arranged in slight overlap. According to an alternative embodiment of the box in accordance with the invention, it is entirely possible to proceed with a bonding of the element 11 on the bottom 6 of the receptacle 10, bonding which will be done by crossing the film 7. According to a general characteristic of the invention, the planar element 11 must be rigid to provide maximum blocking of the film 7 between the vertical walls 3,5 of the receptacle 10; advantageously this planar element 11 will be cut from corrugated cardboard, preferably, although not necessarily, to the dimensions of the bottom 6 of the receptacle 10 in order to constitute a real double bottom. To provide the necessary rigidity to the corrugated cardboard, the flat element 11 will be inserted in such a way that the direction of the grooves 14 is perpendicular to the lines of contact with the vertical walls 3, 5 between which said element 11 is force-fitted.
Conformément aux figures 3 et 4 il sera maintenant donnée une seconde variante de la caisse conforme à l'invention en observant que les parties des figures 3 et 4 qui sont communes aux deux variantes portent les mêmes références que dans les figures 1 et 2.In accordance with FIGS. 3 and 4, a second variant of the box in accordance with the invention will now be given, observing that the parts of FIGS. 3 and 4 which are common to the two variants have the same references as in FIGS. 1 and 2.
Comme dans la première variante, le réceptacle 1 sera avantageusement formé à partir de quatre parois latérales 2,3,4,5, préférentiellement de forme rectangulaire maintenues entre elles pour former une ceinture par exemple en carton ondulé ou analogue solidarisée à un fond 6, pour former de manière très habituelle, un réceptacle 10' tel qu'une caisse américaine sans rabats supérieurs ou une demi-caisse américaine ou encore une barquette à murs simples ou à murs doubles couramment utilisée dans le domaine de 1 ' emballage . Comme dans la variante précédente, il est disposé à l'intérieur du réceptacle 10' une feuille de plastique thermo-rétractable 7 dont les deux extrémités viennent former des rideaux 8,9 de matière libre débordant largement de part et d'autre du
réceptacle 10 ' au delà de deux parois verticales opposées 3 , 5 sur une longueur permettant de recouvrir totalement les articles à emballer comme il a été déjà exposé précédemment. Dans cette deuxième variante, l'élément plan 11' venant comme dans la variante précédente contre- plaquer la partie centrale du film 7 sur le fond 6 du réceptacle 10' présente naturellement toutes les caractéristiques de l'élément plan 11 de la première variante, mais il est complémentairement muni de tenons 15,16 s ' étendant vers l'extérieur dans le plan de l'élément 11' à partir des chants opposés 12,13 dudit élément 11' venant au contact de deux parois latérales 3,5 du réceptacle 10' concourant au blocage des deux rideaux 8,9.As in the first variant, the receptacle 1 will advantageously be formed from four side walls 2,3,4,5, preferably of rectangular shape held together to form a belt, for example of corrugated cardboard or the like secured to a bottom 6, to form in a very usual manner, a receptacle 10 ′ such as an American box without upper flaps or an American half-box or even a tray with single walls or double walls commonly used in the field of packaging. As in the previous variant, there is disposed inside the receptacle 10 'a sheet of heat-shrinkable plastic 7, the two ends of which form curtains 8, 9 of free material projecting widely on either side of the receptacle 10 ′ beyond two opposite vertical walls 3, 5 over a length making it possible to completely cover the articles to be packaged as already explained above. In this second variant, the planar element 11 ′ coming as in the previous variant against the central part of the film 7 on the bottom 6 of the receptacle 10 ′ naturally has all the characteristics of the planar element 11 of the first variant, but it is additionally provided with pins 15,16 extending outwards in the plane of the element 11 'from the opposite edges 12,13 of said element 11' coming into contact with two side walls 3,5 of the receptacle 10 'contributing to the blocking of the two curtains 8.9.
Ces deux tenons 15,16 sur l'élément 11' sont prévus pour collaborer avec deux rainures 17,18 s ' étendant horizontalement à la base des deux parois verticales opposées 3,5 du réceptacle 10' pour former un verrouillage par encliquetage de l'élément 11' après qu'il ait été introduit à force et contre- plaqué sur le fond 6 du réceptacle 10 ' .These two studs 15,16 on the element 11 'are provided to collaborate with two grooves 17,18 extending horizontally at the base of the two opposite vertical walls 3,5 of the receptacle 10' to form a latching locking of the element 11 'after it has been force-fitted and plywood on the bottom 6 of the receptacle 10'.
Les deux rainures 17,18 sont aménagées dans la partie inférieure des parois verticales 3,5 juste au dessus de la ligne de jonction entre lesdites parois 3,5 et le fond 6, sur une longueur au plus égale à la longueur desdites parois et normalement sur une longueur suffisante pour maintenir fermement l'élément 11' contre le fond 6 du réceptacle 10.
Ainsi l'élément 11' encliqueté dans les rainures 17,18 des parois latérales opposées 3,5 non seulement contre-serre par ses chants 12,13 le film 7 contre les mêmes parois verticales 3,5 mais par le jeu des deux tenons 15,16 forme des coins venant enchâsser de manière irréversible la base des rideaux 8,9 dans les rainures 17 et 18. De cette manière, toute traction sur le film 7, par exemple en cas de chute, de choc ou de manutention brusque sera compensée non seulement par l'effet de coincement de la pièce 11' comme dans la première variante mais encore par l'effet de coin des tenons 15,16 enchâssés dans les rainures 17,18 des parois verticales 3,5.The two grooves 17, 18 are arranged in the lower part of the vertical walls 3.5 just above the junction line between said walls 3.5 and the bottom 6, over a length at most equal to the length of said walls and normally over a sufficient length to firmly hold the element 11 'against the bottom 6 of the receptacle 10. Thus the element 11 'snapped into the grooves 17,18 of the opposite side walls 3,5 not only against the greenhouse by its edges 12,13 the film 7 against the same vertical walls 3,5 but by the play of the two tenons 15 , 16 forms corners which irreversibly embed the base of the curtains 8, 9 in the grooves 17 and 18. In this way, any traction on the film 7, for example in the event of a fall, impact or rough handling, will be compensated not only by the wedging effect of the part 11 ′ as in the first variant but also by the wedge effect of the tenons 15, 16 embedded in the grooves 17, 18 of the vertical walls 3.5.
On comprend alors que dans cette variante, on peut éviter, si les charges ne sont pas trop lourdes, de compléter la fixation du film thermo-rétractable 7 au fond 6 du réceptacle 10' par un collage. Un tel montage de l'élément 11' dans le réceptacle 10' par encliquetage est particulièrement adapté au réceptacle du type barquette à murs doubles permettant de masquer extérieurement les deux rainures 17,18 uniquement pratiquées sur le mur intérieur des parois verticales 3,5.It is then understood that in this variant, it is possible to avoid, if the loads are not too heavy, to complete the fixing of the heat-shrinkable film 7 to the bottom 6 of the receptacle 10 'by bonding. Such an assembly of the element 11 ′ in the receptacle 10 ′ by snap-fastening is particularly suitable for the receptacle of the double-walled container type making it possible to mask the two grooves 17,18 externally only made on the interior wall of the vertical walls 3,5.
Naturellement on pourrait imaginer des variantes d'exécution prévoyant par exemple qu'une seule paroi 3,5 comporte une rainure 17 ou 18 même si un tel montage est à l'évidence moins fiable que celui qui vient d'être décrit.
Ici encore, l'élément 11' doit présenter une évidente rigidité pour les raisons déjà évoquées dans la première variante. A cet effet, les tenons 15, 16 seront découpés dans le sens des cannelures, c'est-à- dire en prolongement des deux chants 12,13 contre- bloquant les deux rideaux 8,9 sur les parois latérales opposées 3,5.Naturally one could imagine alternative embodiments providing for example that a single wall 3.5 has a groove 17 or 18 even if such an assembly is obviously less reliable than that which has just been described. Here again, the element 11 ′ must have obvious rigidity for the reasons already mentioned in the first variant. To this end, the studs 15, 16 will be cut in the direction of the grooves, that is to say in extension of the two edges 12, 13 counter-blocking the two curtains 8, 9 on the opposite side walls 3.5.
Il est bien évident que toutes solutions dérivées de 1 ' une ou 1 ' autre des variantes avec ou sans encliquetage de l'élément plan 11,11', par exemple en remplaçant l'un ou l'autre des tenons 15,16 par plusieurs tenons successifs sur l'un et/ou l'autre des chants 12,13 de l'élément 11' ne sortiraient pas du domaine de l'invention, l'Homme du Métier sachant ponctuellement extrapoler les deux variantes principales sous-exposées ; de même ne sortiraient pas du cadre de l'invention toutes exécutions particulières visant à obtenir une caisse de forme générale polygonale, c'est-à-dire comportant plus de quatre faces et ce pour autant que l'élément 11 ou 11 ' puisse être inséré entre deux parois non obligatoirement parallèles mais procurant un contre- serrage en vis-à-vis du film thermo-rétractable 7 entre ledit élément et lesdites parois verticales, avant blocage de l'élément 11.It is obvious that all solutions derived from one or the other of the variants with or without snap-fastening of the planar element 11, 11 ', for example by replacing one or the other of the pins 15, 16 with several successive tenons on one and / or the other of the edges 12, 13 of the element 11 'would not depart from the field of the invention, the skilled person knowing occasionally extrapolate the two main variants underexposed; similarly would not depart from the scope of the invention any particular execution aimed at obtaining a box of generally polygonal shape, that is to say comprising more than four faces and this insofar as the element 11 or 11 ′ can be inserted between two walls which are not necessarily parallel but which provide a counter-clamping in relation to the heat-shrinkable film 7 between said element and said vertical walls, before blocking of element 11.
L'invention est particulièrement applicable pour la préparation de commandes ponctuelles dont le contenu est variable et ne peut donc être fixé à 1 ' avance .
On a représenté sur la figure 5 une demi-caisse 20 parallélépipédique de conditionnement en carton ou analogue pour le transport d'une charge, ladite demi- caisse comprenant une ceinture latérale 21 formée de quatre parois verticales 22 et d'un fond horizontal 23 formé par quatre rabats solidarisé avec ladite ceinture via des lignes de jonction 24, et un matériau plastique thermo-rétractable en film 25 destiné à l'emballage et au maintien en place de la charge (non représentée) .The invention is particularly applicable for the preparation of punctual orders whose content is variable and therefore cannot be fixed in advance. FIG. 5 shows a parallelepipedal half-box 20 for packaging in cardboard or the like for transporting a load, said half-box comprising a lateral belt 21 formed by four vertical walls 22 and a horizontal bottom 23 formed by four flaps secured to said belt via junction lines 24, and a heat-shrinkable plastic film material 25 intended for packaging and holding the load in place (not shown).
La demi-caisse comporte une plaque rigide rectangulaire 26 rapportée, plaquant le film thermorétractable sur la face interne 27 du fond de la caisse en laissant s'échapper de part et d'autre de deux bords opposés en vis-à-vis 28 de la plaque, des portions 29 et 30 de rideau de matière libre s ' étendant depuis les bords 28 sur une longueur suffisante pour se recouvrir l'une l'autre en enveloppant totalement la charge et bloquer ladite charge par rétraction thermique du film.The half-body has a rigid rectangular plate 26 attached, flattening the heat-shrinkable film on the internal face 27 of the bottom of the body while letting escape on either side of two opposite edges facing 28 of the plate, portions 29 and 30 of curtain of free material extending from the edges 28 over a length sufficient to cover each other by completely enveloping the load and blocking said load by thermal shrinkage of the film.
La plaque 26 est insérée entre au moins deux premières parois verticales opposées de sorte que lesdits bords soient en contact ou sensiblement en contact via le film en matériau plastique 25 avec au moins une partie des lignes de jonction 24 desdites premières parois .The plate 26 is inserted between at least two first opposite vertical walls so that said edges are in contact or substantially in contact via the plastic film 25 with at least part of the joining lines 24 of said first walls.
Il faut entendre, dans l'ensemble du texte, "en contact via le film" par affleurant le film plastique, lui-même en contact avec la ligne de
jonction et/ou de préférence en pression sur le film plastique qui est lui-même en contact avec la ligne de jonction.Throughout the text, we must hear "in contact via the film" by being flush with the plastic film, itself in contact with the line of junction and / or preferably by pressure on the plastic film which is itself in contact with the junction line.
La caisse comporte des moyens de blocage 31 de la plaque 26 contre le fond 23.The box comprises blocking means 31 of the plate 26 against the bottom 23.
Les moyens 31 de blocage comportent des portions de volets intérieurs 32 directement collés sur les faces internes 33 des premières parois verticales 22, la périphérie inférieure 34 des volets intérieurs venant en butée avec les bords supérieurs 35 de la plaque pour assurer le blocage, coinçant ainsi le film plastique 25 entre la tranche inférieure des volets 32, la face interne de la première paroi et l'extrémité de la face supérieure du bord de la plaque.The blocking means 31 comprise portions of internal flaps 32 directly bonded to the internal faces 33 of the first vertical walls 22, the lower periphery 34 of the internal flaps coming into abutment with the upper edges 35 of the plate to ensure blocking, thus wedging the plastic film 25 between the lower edge of the flaps 32, the internal face of the first wall and the end of the upper face of the edge of the plate.
Plus précisément, en référence à la figure 6, la demi-caisse est constituée à partir d'un flan comprenant les quatre parois rectangulaires 22 séparées par des lignes de pliage verticales 36 munies d'un rabat rectangulaire inférieur 37 destiné à former le fond 23, rattaché à la partie inférieure de la caisse par une ligne de pliage 24 alignée avec celle du rabat adjacent.More specifically, with reference to FIG. 6, the half-body is formed from a blank comprising the four rectangular walls 22 separated by vertical fold lines 36 provided with a lower rectangular flap 37 intended to form the bottom 23 , attached to the lower part of the box by a fold line 24 aligned with that of the adjacent flap.
Deux volets intérieurs 32 collés sur deux parois non adjacentes sont prévues.Two interior flaps 32 bonded to two non-adjacent walls are provided.
Ils sont par exemple rectangulaires et de surface un peu inférieure à celle des parois 22 concernées.They are for example rectangular and of a surface slightly less than that of the walls 22 concerned.
La périphérie inférieure 34 des volets est située à une distance e_ correspondant à 1 ' épaisseur de la
plaque 26 qui vient se glisser en butée sous lesdites périphéries .The lower periphery 34 of the flaps is situated at a distance e_ corresponding to the thickness of the plate 26 which slides into abutment under said peripheries.
La figure 7 est une vue de dessus de la figure 5 montrant les deux parois 22 en vis-à-vis, chacune munie de deux volets intérieurs 32 de blocage de la plaque 26 contre le fond constitué par les rabats 37.FIG. 7 is a top view of FIG. 5 showing the two facing walls 22, each provided with two internal flaps 32 for blocking the plate 26 against the bottom formed by the flaps 37.
Le film plastique 25 (en trait mixte sur la figure) est par ailleurs percé d'orifices 38 circulaires et de petit diamètre, par exemple quatre orifices disposés sur une ligne parallèle à la ligne de jonction 24, à une distance de 1 à 5 cm de cette dernière, par exemple 2 cm.The plastic film 25 (in phantom in the figure) is moreover pierced with circular orifices 38 of small diameter, for example four orifices arranged on a line parallel to the junction line 24, at a distance of 1 to 5 cm. of the latter, for example 2 cm.
Les orifices ont un ou deux centimètres.The holes are one or two centimeters.
Des points de colle 39 ont été injectés au travers permettant le collage direct de la face inférieure de la plaque rapportée 26 sur la face supérieure, plane, des grands rabats jointifs 37 qui constituent la partie supérieure du fond, les petits rabats étant quant à eux repliés à l'extérieur et collés. Dans un mode de réalisation, le film plastique 25 est également collé sur un ou sur ses deux côtés sur les faces de carton attenante, par exemple par deux lignes 40 de colle dite "hot melt" .Glue dots 39 were injected through allowing direct bonding of the underside of the added plate 26 on the upper, flat face, large contiguous flaps 37 which constitute the upper part of the bottom, the small flaps being in turn folded outside and glued. In one embodiment, the plastic film 25 is also glued on one or on its two sides to the adjoining cardboard faces, for example by two lines 40 of so-called "hot melt" glue.
Les figures 8 à 10 montrent un autre mode de réalisation du contenant primaire 49 ou boîte obtenue à partir du flan 50.FIGS. 8 to 10 show another embodiment of the primary container 49 or box obtained from the blank 50.
La boîte 49 est en forme de barquette comprenant un fond rectangulaire 51 comportant quatre premiers rabats rectangulaires égaux deux à deux 52 et 53
reliés respectivement à chaque côté du fond par des lignes de pliage 54 perpendiculaires entre elles.The box 49 is in the form of a tray comprising a rectangular bottom 51 comprising four first rectangular flaps equal in pairs 52 and 53 connected respectively to each side of the bottom by fold lines 54 perpendicular to each other.
Deux premiers rabats opposés 53, par exemple correspondant aux petits côtés, comprennent chacun de part et d'autre, des seconds rabats rectangulaires 55 rattachés aux périphéries latérales desdits premiers rabats .Two first opposite flaps 53, for example corresponding to the short sides, each comprise on either side, second rectangular flaps 55 attached to the lateral peripheries of said first flaps.
Les seconds rabats 55 comportent en partie basse des parties évidées 56 rectangulaires de hauteur égale ou sensiblement égale à celle de la plaque 57, agencée pour permettre le blocage vertical de la plaque 57 (Cf. figures 8 et 9) préalablement munie sur sa face inférieure d'une feuille plastique 58, par exemple solidarisée par collage, qui vient s'encastrer en dessous des tranches inférieures 59 des seconds rabats 55 en coinçant le film 58 comme montré à la figure 9.The second flaps 55 have, in the lower part, rectangular recessed portions 56 of height equal to or substantially equal to that of the plate 57, arranged to allow the vertical blocking of the plate 57 (see FIGS. 8 and 9) previously provided on its lower face. a plastic sheet 58, for example secured by gluing, which comes to be embedded below the lower edges 59 of the second flaps 55 by wedging the film 58 as shown in FIG. 9.
Le film 58 décrit ainsi un trajet horizontal parallèle au fond 60 de la boîte, puis vertical sur une petite portion 61 inférieure de la paroi verticale 53, puis horizontale 62 vers l'intérieur de la boîte, avant de partir librement vers la charge et/ou le haut et l'intérieur de ladite boîte, de façon à pouvoir se rabattre ensuite sur la charge 63 (en trait mixte sur la figure) comme montré avec les flèches 64.The film 58 thus describes a horizontal path parallel to the bottom 60 of the box, then vertical over a small lower portion 61 of the vertical wall 53, then horizontal 62 towards the inside of the box, before leaving freely towards the load and / or the top and the inside of said box, so that it can then be folded back onto the load 63 (in dashed lines in the figure) as shown with the arrows 64.
Dans un mode de réalisation les moyens de blocage de la plaque peuvent même comporter, ou être constitués par, un produit à emballer, plus haut que
les autres, qui viendrait en butée sur la face interne du couvercle (non représenté) lorsque le couvercle est mis en place.In one embodiment, the plate blocking means may even comprise, or be constituted by, a product to be packaged, higher than the others, which would come into abutment on the internal face of the cover (not shown) when the cover is put in place.
Les figures 11 à 13 montrent un autre mode de réalisation d'une boîte 70 pour caisse selon l'invention avec plaque rectangulaire 71 muni d'un film plastique 72 préencollé sur la face inférieure de la plaque.Figures 11 to 13 show another embodiment of a box 70 for crate according to the invention with rectangular plate 71 provided with a plastic film 72 pre-glued on the underside of the plate.
Le film comprend par exemple des orifices ou des évidements 73, par exemple en forme de lunules de petite dimension (de 0 , 5 cm à 3 cm de dimension maximale, par exemple 1 cm) par exemple deux rangées de 10 lunules 73 (2 fois 5) en quinconce, c'est à dire décalées, propres à être disposées en dessous et à 1 ' aplomb des tranches de parois internes précisées ci-après, ou directement à proximité vers l'intérieur de la boîte.The film includes for example orifices or recesses 73, for example in the form of small size lunules (from 0.5 cm to 3 cm maximum size, for example 1 cm) for example two rows of 10 lunules 73 (2 times 5) staggered, that is to say offset, suitable for being arranged below and vertically in line with the internal wall sections specified below, or directly near towards the interior of the box.
Ces lunules vont permettre le collage direct carton sur carton, comme décrit ci-avant. Plus précisément la boîte 70 en forme de barquette comprend quatre parois rectangulaires formées par deux petits rabats 74 et deux grands rabats 75 rattachés au fond 76 par des lignes de pliage ou de jonction 77. Chaque petit rabat comprend deux seconds rabats latéraux rectangulaires 78, avec évidement 79 inférieur de blocage de la plaque contre le fond comme décrit ci-avant.
Ces évidements sont sensiblement rectangulaires, de largeur e_ entre la prolongation de la ligne de pliage 77 et le bord inférieur du rabat 78, et s'étendent sur toute la longueur du second rabat 78. Les seconds rabats 78 sont par ailleurs collés sur les faces internes des grands rabats 75.These lunules will allow direct bonding cardboard on cardboard, as described above. More precisely, the box 70 in the form of a tray comprises four rectangular walls formed by two small flaps 74 and two large flaps 75 attached to the bottom 76 by fold or junction lines 77. Each small flap comprises two second rectangular lateral flaps 78, with lower recess 79 for blocking the plate against the bottom as described above. These recesses are substantially rectangular, of width e_ between the extension of the fold line 77 and the lower edge of the flap 78, and extend over the entire length of the second flap 78. The second flaps 78 are also glued to the faces internal of large flaps 75.
Les grands rabats 75 comprennent quant à eux sur leur périphérie horizontale supérieure des troisièmes rabats rectangulaires 81 rattachés à ces derniers par des doubles lignes de pliage 82, d'épaisseur égale ou un peu supérieure à celle des seconds rabats 78, de façon à être rabattus, et collés sur les faces externes 83 dirigées du côté de 1 ' intérieur de la boîte des seconds rabats 78, comme représenté sur la figure 12.The large flaps 75 comprise, on their upper horizontal periphery, third rectangular flaps 81 attached to the latter by double fold lines 82, of thickness equal to or slightly greater than that of the second flaps 78, so as to be folded down , and glued to the external faces 83 directed towards the inside of the box of the second flaps 78, as shown in FIG. 12.
Le film en matériau plastique 72 préalablement introduit dans la barquette formée ou solidarisée à la plaque 71 avant d'être introduit (Cf. figure 11), est ainsi coincé horizontalement entre les tranches inférieures 84 des seconds rabats 85 et des troisièmes rabats sur une plus grande distance horizontale, la largeur 1 des troisièmes rabats étant calculée pour permettre audit rabat de frôler et/ou coincer également la plaque contre le fond sur le film en matériau plastique.The plastic film 72 previously introduced into the tray formed or secured to the plate 71 before being introduced (see FIG. 11), is thus wedged horizontally between the lower edges 84 of the second flaps 85 and of the third flaps on one more large horizontal distance, the width 1 of the third flaps being calculated to allow said flap to graze and / or also wedge the plate against the bottom on the plastic film.
Dans la pratique les troisièmes rabats pourront être repliés uniquement après introduction du film et de la plaque, venant ainsi encore consolider le blocage, ce qui va permettre le transport d'objets
particulièrement lourds comme des ustensiles de cuisine par exemple.In practice the third flaps can be folded only after introduction of the film and the plate, thus further consolidating the blocking, which will allow the transport of objects particularly heavy like kitchen utensils for example.
Les figures 14 à 17 montrent un autre mode de réalisation de l'invention. La boîte 90 est ici obtenue à partir d'un flan 91 en forme de ceinture munie de quatre volets rectangulaires 92, 93, 94 et 95 formant les parois verticales de la caisse obtenue à partir de la boîte. Une languette latérale de collage est également prévue de façon connue .Figures 14 to 17 show another embodiment of the invention. The box 90 is here obtained from a blank 91 in the form of a belt provided with four rectangular flaps 92, 93, 94 and 95 forming the vertical walls of the box obtained from the box. A lateral bonding tab is also provided in a known manner.
Chaque volet comprend un rabat inférieur, à savoir les grands volets 92 et 94 comprennent chacun un rabat rectangulaire 96 destiné à former la face jointive et plane du fond contre laquelle la plaque 97 va être bloquée, et les petits volets 93 et 95 comprennent un rabat identique 98 de forme rectangulaire plus haute que cette du petit volet adjacent auquel il est rattaché.Each flap comprises a lower flap, namely the large flaps 92 and 94 each comprise a rectangular flap 96 intended to form the contiguous and flat face of the bottom against which the plate 97 will be locked, and the small flaps 93 and 95 comprise a flap identical 98 of rectangular shape higher than that of the small adjacent flap to which it is attached.
Chaque rabat 98 comporte une languette centrale 99 détachable dudit rabat, mais rattachée par une ligne de pliage 100 décalée par rapport aux lignes de jonction 101, alignées, des rabats 92 à 95, avec le fond.Each flap 98 has a central tab 99 detachable from said flap, but attached by a fold line 100 offset from the junction lines 101, aligned, flaps 92 to 95, with the bottom.
On va maintenant décrire la formation de la demi- caisse selon le mode de réalisation de l'invention en référence aux figures 16A, 16B et 17 tout d'abord, puis 14 et 15.We will now describe the formation of the half-box according to the embodiment of the invention with reference to FIGS. 16A, 16B and 17 first, then 14 and 15.
On replie tout d'abord les rabats 98 (Cf. figure 16B) à 180° pour venir les plaquer sur les faces
internes des volets 93 et 95 avec lesquels ils sont par exemple provisoirement solidarisés par des points de colle 102.First fold the flaps 98 (Cf. figure 16B) at 180 ° to come and press them on the faces internal flaps 93 and 95 with which they are for example provisionally secured by dots of adhesive 102.
Les languettes 99 par exemple de forme rectangulaire, restent par contre à l'horizontal dans le même plan que les autres rabats 96, un évidement complémentaire 99' apparaissant donc dans lesdits rabats 98.The tabs 99, for example of rectangular shape, on the other hand remain horizontal in the same plane as the other flaps 96, a complementary recess 99 ′ therefore appearing in said flaps 98.
La boîte est ensuite formée, par exemple autour d'un mandrin, les grands rabats rectangulaires 96 étant au dessus et les languettes 99 collées en dessous desdits rabats 96 (Cf. figure 17) .The box is then formed, for example around a mandrel, the large rectangular flaps 96 being above and the tabs 99 glued below said flaps 96 (see FIG. 17).
On obtient alors la demi-caisse de la figure 14.We then obtain the half-body of Figure 14.
La plaque 97 munie du film 103, par exemple de dimension transversale un peu inférieure à la longueur entre rabats relevés 98 pour permettre son introduction, est alors introduite et vient bloquer le film 103 sur le fond plat de la caisse.The plate 97 provided with the film 103, for example of transverse dimension a little less than the length between raised flaps 98 to allow its introduction, is then introduced and comes to block the film 103 on the flat bottom of the box.
Puis les rabats 98 sont rabattus (flèche 104) et viennent constituer les moyens de blocage de la plaque 97 sur le fond, plaque avec laquelle ils sont collés (Cf. figure 15), le film 103 s ' échappant sur les côtés comme montré sur la figure.Then the flaps 98 are folded down (arrow 104) and come to constitute the means for blocking the plate 97 on the bottom, plate with which they are glued (cf. FIG. 15), the film 103 escaping on the sides as shown on the figure.
Dans les modes préférés de réalisation de l'invention le film est d'un seul tenant.In the preferred embodiments of the invention, the film is in one piece.
Il pourrait être en deux morceaux fixés de part et d'autre et laissant entre les deux un espace dénué de film permettant un excellent collage direct de la plaque sur le fond.
Il est important que le dessus du fond soit parfaitement plat pour permettre une bonne tenue du film et un plaquage efficace complété d'un collage, de ladite plaque sur le film. Dans les modes de réalisation plus particulièrement décrit ici la plaque est en carton ondulé dont le sens des cannelures est perpendiculaire aux lignes de contact avec les premières parois verticales entre lesquelles ladite plaque est insérée, et la plaque recouvre totalement le fond de la caisse pour constituer un double fond.It could be in two pieces fixed on either side and leaving between the two a space devoid of film allowing an excellent direct bonding of the plate on the bottom. It is important that the top of the bottom is perfectly flat to allow good holding of the film and effective plating completed by bonding of said plate on the film. In the embodiments more particularly described here, the plate is made of corrugated cardboard, the direction of the grooves of which is perpendicular to the contact lines with the first vertical walls between which said plate is inserted, and the plate completely covers the bottom of the body to constitute a double bottom.
On va maintenant décrire un procédé de formation d'une caisse de conditionnement en carton ou analogue pour le transport d'une charge du type décrit ci- avant en référence à la figure 18 donnant schématiquement les étapes suivies.We will now describe a method of forming a cardboard packaging box or the like for transporting a load of the type described above with reference to FIG. 18 schematically giving the steps followed.
Une première étape 110 consiste à former le fond et les parois verticales de la caisse qu'on laisse ouverte sur le dessus. Une telle formation peut par exemple être effectuée autour d'un mandrin à partir d'une ceinture de volets comme décrit dans les documents FR-A-2 629 012 ou FR-A-2 665 137 .A first step 110 consists in forming the bottom and the vertical walls of the box which are left open on the top. Such training can for example be carried out around a mandrel from a flap belt as described in documents FR-A-2 629 012 or FR-A-2 665 137.
Les moyens de blocage peuvent être dans ce cas soit les volets intérieurs de blocage collés sur les parois, soit des moyens d' encliquetage, le tout étant complété par un collage au travers du ou des films plastiques .
Puis on forme (étape 111) un élément composite comprenant la plaque et le matériau plastique préalablement solidarisé au moins provisoirement à la dite plaque par collage (étape 112) . On introduit ensuite par exemple par pistonnage en force ou en biais (étape 113) l'élément composite dans ladite caisse jusqu'à venir en position de blocage en butée contre le fond de la caisse en maintenant si nécessaire les bords libres du film plastique vers l'extérieur, par exemple par des busettes de soufflage.The blocking means may in this case be either the internal blocking flaps glued to the walls, or snap-fastening means, the whole being completed by bonding through the plastic film (s). Then a composite element is formed (step 111) comprising the plate and the plastic material previously secured at least temporarily to said plate by gluing (step 112). Then, for example, by force or bias plunging (step 113), the composite element is introduced into said box until it comes into locking position in abutment against the bottom of the box, maintaining if necessary the free edges of the plastic film towards outside, for example by blowing nozzles.
On vient ensuite (étape 114) placer la charge dans l'emballage, on referme (115) les extrémités du film plastique dessus, qui est thermosoudé en 116, puis on réalise la constriction thermique (étape 117) par exemple en passant dans un tunnel chauffant de façon connue en elle-même.We then come (step 114) to place the load in the packaging, we close (115) the ends of the plastic film on it, which is heat sealed at 116, then we perform thermal constriction (step 117) for example by passing through a tunnel heating in a manner known per se.
On referme ensuite l'emballage (étape 118) en disposant le couvercle et/ou en le refermant simplement avec collage s'il s'agit de rabats supérieurs, avant d'évacuer (119) l'emballage.The packaging is then closed (step 118) by placing the cover and / or simply closing it with gluing if it is upper flaps, before removing (119) the packaging.
Un autre procédé consiste à introduire le film plastique avant d'introduire la plaque.Another method consists in introducing the plastic film before introducing the plate.
Il présente ainsi un meilleur maintien du film en matériau plastique lors de la mise en place de la plaque .It thus has better retention of the plastic film when the plate is put in place.
Dans un mode avantageux, où on utilise un mandrin avant de former le fond et les parois de ladite
caisse, on plaque l'élément composite sur le fond du mandrin et on forme ensuite la caisse par dessus.In an advantageous mode, where a mandrel is used before forming the bottom and the walls of said body, the composite element is placed on the bottom of the mandrel and then the body is formed on top.
On peut également former le fond et une partie des parois verticales de la caisse qu'on laisse ouverte sur le côté, former l'élément composite comprenant la plaque et le matériau plastique solidarisé au moins provisoirement à la dite plaque et introduire l'élément composite dans ladite caisse par le côté avant de le refermer, mettre en place la charge, thermorétracter et mettre le couvercle de la boîte.It is also possible to form the bottom and part of the vertical walls of the box which are left open on the side, to form the composite element comprising the plate and the plastic material secured at least temporarily to said plate and to introduce the composite element. in the said box from the side before closing it, placing the load, heat shrinking and putting on the box cover.
L'invention propose également un dispositif de fabrication d'une caisse de conditionnement en carton ou analogue pour le transport d'une charge, ladite caisse comprenant une ceinture latérale formée d'au moins quatre parois verticales et d'un fond horizontal solidarisé avec la ceinture via des lignes de jonction, et un matériau plastique thermorétractable en film destiné à l'emballage et au maintien en place de ladite charge. Le dispositif va maintenant être décrit en référence à la figure 19.The invention also provides a device for manufacturing a cardboard packaging box or the like for transporting a load, said box comprising a lateral belt formed by at least four vertical walls and a horizontal bottom secured to the belt via junction lines, and a heat-shrinkable plastic film material intended for packaging and holding said load in place. The device will now be described with reference to FIG. 19.
Les moyens qu'il met en oeuvre sont une combinaison de moyens connus et/ou adaptés de façon à la portée de l'homme du métier cherchant à mécaniser la fabrication d'une boîte selon l'invention, comme des machines formeuses de barquettes et/ou de boîtes polygonales à quatre ou huit côtés autour d ' un mandrin.
La nouveauté provient notamment de l'application en combinaison de ces machines permettant d'obtenir l'emballage selon l'invention.The means which it implements are a combination of known means and / or adapted in a manner accessible to the person skilled in the art seeking to mechanize the manufacture of a box according to the invention, such as tray-forming machines and / or polygonal boxes with four or eight sides around a mandrel. The novelty comes in particular from the application in combination of these machines making it possible to obtain the packaging according to the invention.
Le dispositif comporte donc des moyens 120 de formation du fond et des parois verticales de la caisse C à partir de flans F alimentés de façon connue, des moyens 121 de présentation d'un élément composite comprenant une plaque 122 superposée au matériau plastique en film 123 avantageusement solidarisé au moins provisoirement à la dite plaque.The device therefore comprises means 120 for forming the bottom and vertical walls of the box C from blanks F supplied in a known manner, means 121 for presenting a composite element comprising a plate 122 superimposed on the plastic film material 123 advantageously secured at least temporarily to said plate.
Les moyens 121 comprennent par exemple, un dévideur 124 de film, des moyens 125 perceurs d'orifices par exemple par chauffage, et des moyens 126 d'amener de la plaque 122 de carton au dessus du film, avec collage par des moyens d'injection 127, et des moyens 128 d'introduction en force ou en biais de l'élément composite, comprenant par exemple un bras à bascule ou un piston, dans ladite caisse jusqu'à plaquer le film thermo-rétractable sur la face interne du fond de la caisse en laissant s'échapper et en maintenant (rouleaux 129) de part et d'autre de deux bords opposés en vis à vis de ladite plaque, des portions de rideau de matière libre s 'étendant depuis lesdits bords sur une longueur suffisante pour se recouvrir l'une l'autre en enveloppant totalement la charge et bloquer ladite charge par rétraction thermique du film lors de leur rabattement.
La caisse comprend quant à elle les moyens propres à plaquer ledit élément en appuyant sur la plaque rigide rapportée.The means 121 comprise, for example, a film reel 124, means 125 for piercing orifices, for example by heating, and means 126 for bringing cardboard plate 122 above the film, with bonding by means of injection 127, and means 128 for force or bias introduction of the composite element, comprising for example a rocking arm or a piston, into said box until the heat-shrinkable film is pressed against the inner face of the bottom of the body while letting escape and maintaining (rollers 129) on either side of two opposite edges opposite said plate, curtain portions of free material extending from said edges over a sufficient length to overlap each other by completely enveloping the load and block said load by thermal shrinkage of the film during their folding. The body, for its part, comprises the means specific to pressing said element by pressing on the attached rigid plate.
Le dispositif comporte également des moyens 131 de mise en place de la charge, des moyens 130 de rabattage des parties de film sur la charge, et des moyens de thermoscellage 132 desdites parties de filmThe device also comprises means 131 for placing the load, means 130 for folding down the film parts on the load, and heat sealing means 132 for said film parts.
1 ' une sur 1 ' autre .1 'over one'.
Il comprend ensuite des moyens 133 de thermoconstriction du film et de refermeture par un couvercle 134 ou rabattage de rabat préencollé par des moyens 135.It then comprises means 133 for thermoconstricting the film and for reclosing by a cover 134 or folding down the flap pre-glued by means 135.
Dans une variante où l'emballage est formé autour d'un mandrin, les moyens 128 sont remplacés par des moyens de plaquage de l'élément composite sur le fond du mandrin avant formation de la caisse autour.
In a variant where the packaging is formed around a mandrel, the means 128 are replaced by means for plating the composite element on the bottom of the mandrel before the box is formed around.
