Definitions
- the present invention relates to a method of manufacturing a package and the package thus obtained.
- the present invention aims to solve these technical problems satisfactorily.
- This object is achieved by a method of manufacturing a package from a foldable box with a bottom with flaps, characterized in that a flexible envelope is fixed by one of its end edges on the outer face of one of the bottom flaps of the box folded flat, then unfolded and the box is shaped by inversion by passing said envelope through the bottom between the flaps to fill the interior volume of the box .
- said envelope is sealed before the box is shaped so as to form a sealed internal bag, the opening of which opens onto the upper face of the box.
- said envelope is sealed before the box is shaped so as to form an internal inflatable bag.
- the internal inflatable bag is produced with two walls delimiting, on the one hand, between them, a peripheral inflatable enclosure and, on the other hand, a central product storage chamber.
- the length of said envelope is adjusted and fixed on the bottom flap so that, after shaping the body, said envelope covers at least all the height of the interior volume and optionally forms cuffs exteriors.
- said envelope is fixed to one of the flaps of a so-called automatic bottom or of a so-called semi-automatic bottom.
- the bottom flap carrying the envelope is placed and fixed under the adjacent flaps.
- a manufacturing variant there is produced on two opposite flaps of the bottom and, in particular, on the flap which is intended to carry the envelope, a dotted slitting so as to form fold lines defining a central triangle whose apex is located substantially in the middle of the free edge of the flap.
- a pivoting tongue is used to cut and fix the end edge of the envelope by means of a U-shaped cutout for carrying the envelope.
- said envelope is fixed by means of a double-sided adhesive strip.
- said envelope is fixed on a joined flap.
- Another object of the invention is a package, characterized in that it comprises a foldable box with a bottom with flaps, the interior volume of which is provided with a flexible envelope passing through the bottom between the flaps and fixed by the one of its end edges to the outer face of one of said flaps.
- the bottom with flaps is a so-called automatic bottom or a so-called semi-automatic bottom.
- the bottom is with contiguous flaps.
- two opposite flaps from the bottom and, in particular, the flap intended to carry the envelope are provided with dotted slots forming fold lines which define a central triangle whose apex is situated substantially in the middle from the free edge of the flap.
- the bottom flap intended to carry the envelope comprises a U-shaped cutout closed by a pivoting tab making it possible to press and fix the end edge of the envelope in the cutout.
- the box is made of cardboard and said envelope is a waterproof bag made of waterproof plastic, the opening of which opens onto the upper face of the box.
- said envelope consists of a sheet folded with bellows, or of a sheath or else of an inflatable bag or even of a sheet of cellular material.
- the sealed packaging according to the invention thus comprises an assembly intended to be delivered ready for use and consisting of a box with its attached interior lining.
- the manufacturing process is particularly simple, easy to implement and therefore very economical. It can also be easily automated due to the limited number of additional operations to be carried out from the production of the boxes.
- the packaging of the invention offers airtight packaging and easy assembly which can be in different forms depending on the intended application.
- the flexible covering envelope is fixed firmly to the body at least by its lower part and it fits perfectly with the internal walls, which guarantees optimum packaging capacity.
- an envelope made of shock absorbing material (cellular type or double-walled inflatable or even heat-shrinkable) allows applications for the packaging of fragile products.
- packaging of the invention can be made easily biodegradable and / or recyclable by providing a detachable attachment of the envelope to the box.
- the invention will be better understood on reading the description which follows, accompanied by the drawings in which: - Figures 1 to 8 show perspective views of an embodiment of the sealed package of the invention during the successive phases of its manufacture;
- FIG. 9 shows perspective views of a second embodiment of the packaging of the invention during manufacture in intermediate arrangements corresponding respectively to those of Figures 2, 3 and 4;
- FIG. 12 and 13 show perspective views of a third embodiment of the invention in an arrangement corresponding to that of Figure 1.
- FIG. 1 represents a box 1, folded flat, of the "American box” type, for example made of cardboard with a bottom with notched flaps lla, lld, separated by cutouts 14.
- the flaps lla-lld can be contiguous or normal and the bottom 10 can be a so-called automatic bottom, that is to say closable by means automatic or a so-called semi-automatic bottom.
- the envelope 2 is here in the form of a waterproof plastic bag with side bellows 21 and an opening 22 arranged opposite the fixed end 20.
- the envelope 2 is a simple sheet of plastic material or a sheet folded with bellows or else a sheet provided with internal cells and the fixing of its end edge 20 in duplicate on the flap 11a of the box creates at the same time a seal sealing said end.
- the envelope 2 can also consist of an optionally heat-shrinkable sheath or an airbag.
- the width of the envelope 2 is less than or equal to the width of the flap 11a. Its length depends, on the other hand, on the packaging capacity to be created and on the advisability of making exterior cuffs after assembly (see Figure 6).
- the envelope 2 garnish at least the entire height of the interior volume. Then unfold the box 1 and it is shaped as shown in Figure 2, by applying lateral pulls in the directions F. The effect of this movement is to release the upper opening 12 (shown here below in the inverted position) and the lower opening corresponding to the level of the bottom 10.
- the bottom 10 is closed by tilting the flaps 11a to 11d, as shown in FIGS. 3, 4 and 5 by passing the free end 22 of the envelope 2 through the bottom thus formed, by the space between the flaps.
- the envelope 2 is thus folded back on itself in the direction of the arrow f (FIG. 3) to bypass the inner edge of the flap 11a before engaging in the interior volume of the body 1.
- the flap 11a carrying the envelope 2 is disposed and fixed under the adjacent flaps 11b, 11d as shown in FIGS. 4 and 5.
- the bottom 10 is closed by connection (stapling, gluing, etc.) of the flaps 11a, 11b, lld on one side and of the flaps 11b, lie, lld on the other side, by trapping the edge end 20 of the casing 2.
- the casing 2 is fixed to the flap 11a by means of at least one double-sided adhesive strip which makes it possible by this same means to fix the adjacent flaps llb.lld.
- the body 1 is here symmetrical and the lower flaps lla, lld of the bottom 10 are identical to the upper flaps 13.
- the casing 2 thus adorns the interior volume of the body 1 and its opening 22 opens onto the upper face of the body 1 at through the opening 12 to form a sealed internal bag.
- the length of the envelope 2 is sufficient so that it is possible to create external cuffs 23 which at least partially cover the upper flaps 13 of the body 1.
- the packaging is then available for packaging the P products.
- the P products When the P products are packaged, it is possible to seal the bag 2 as shown in FIG. 7, for example by closing its opening 22 by means of a link. 3 or any other means. Then the opening 12 is closed by folding the flaps 13, so as to enclose the bag 2 inside.
- An adhesive strip 4 is optionally applied to the contiguous area of the flaps 13 to obtain a compact package.
- the envelope 2 is inflatable, it is possible to arrange the products directly in contact with the internal walls of the box 1 when the envelope is deflated. Pressurization, for example with compressed air of the envelope 2 then allows the products to be wedged against the walls of the box and thus avoids any displacement or shocks inside the closed package.
- a variant consists in making the envelope 2 with two walls delimiting on the one hand, between them, a peripheral inflatable enclosure and, on the other hand, a central product storage chamber. In the embodiment of FIGS.
- the bottom flaps 10 are no longer notched as previously but the two opposite flaps 11a, 11c are grooves so as to define fold lines 15. Grooving is obtained for example by means of dotted slitting and the fold lines 15 define three triangles. The apex 15a of the central triangle is located substantially in the middle of the free edge of the flaps lla, llc to allow a contiguous folding.
- the envelope 2 is fixed to one of the flaps 11, 11c as illustrated in FIG. 9 and described above.
- the upper flaps 13 are preferably made with a grooving of the type of that of the bottom 10 without this provision being mandatory.
- This embodiment has the advantage of being very simple to manufacture since the box is no longer a folded and glued cardboard strip to form a tube or belt with a quadrilateral section.
- FIGS. 12 and 13 Another embodiment shown in FIGS. 12 and 13 consists in providing a pivoting tongue 16 provided, on its internal face, with a fixing means such as an adhesive or a coating of heat-sealable material.
- the tongue 16 is produced by a U-shaped cutout 16a of the flap 11a, in which the end edge 20 is pressed and fixed. of the casing 2, after pivoting of the tongue 16 ( Figure 13).
- This tongue 16 also reinforces the anchoring of the envelope 2 on the body 1 by trapping in a firm and resistant manner at least part of the edge 20 of said envelope and without creating any additional thickness.
