The upper opening has handles for manipulating the utensil by a user, and a fixation unit to fix an edge of an opening of a flexible bag (2), where height of the utensil is lesser than that of the bag in deployed position. An upper part of the utensil is widened to form a removable funnel, where the utensil is raised and redeposited on content and horizontally distributed by gravity in the bag, each time its lower conical part is filled during filling of the bag.

Description

La présente invention concerne un procédé et un ustensile pour remplir manuellement des sacs devant contenir un grand nombre d'éléments de petites dimensions par rapport au sac. Il peut en particulier s'agir de remplissage de sacs par des déchets tels qu'il peuvent se produire sur un chantier de construction. Un autre exemple plus spécifique consiste au remplissage d'un sac par un tailleur de pierre ou un sculpteur qui produit beaucoup de déchets (gravats). Il peut cependant également s'agir de débris de végétation par exemple de feuilles, d'herbe coupée etc..The present invention relates to a method and utensil for manually filling bags to contain a large number of small items relative to the bag. It may in particular be filling bags with waste such as may occur on a construction site. Another more specific example is the filling of a bag by a stonecutter or a sculptor who produces a lot of rubbish. However, it can also be debris of vegetation for example leaves, cut grass etc.

Il est généralement difficile et peu pratique de remplir un sac complètement souple si l'on est seul. La difficulté consiste p.e. à le maintenir ouvert d'une main et le remplir de l'autre. Le sac souple laissé à lui-même s'applatit et ne présente aucun volume de réception.It is usually difficult and impractical to fill a completely flexible bag if you are alone. The difficulty lies in keeping it open with one hand and filling it with the other. The flexible bag left to itself is flat and has no reception volume.

On a proposé différents systèmes pour remédier à ce problème.Different systems have been proposed to address this problem.

L'art antérieur à cet égard peut être représenté par de nombreux documents notamment les documents de brevet suivants :

  • US 6450461 , US 4664348 , US 5879039 , US2006011785A1 et

The prior art in this respect can be represented by numerous documents including the following patent documents:
  • US 6450461 , US 4664348 , US 5879039 , US2006011785A1 and
  • US 3822524 .

Aucun de ces documents ne propose une solution simple et économique au remplissage manuel d'un sac avec des matériaux tels des gravats, feuilles etc.., en utilisant un ustensile simple, peu coûteux, et peu encombrant par rapport au sac.None of these documents offers a simple and economical solution to manual filling of a bag with materials such as rubble, sheets etc., using a simple utensil, inexpensive, and compact in relation to the bag.

La présente invention propose un ustensile extrêmement simple jouant le role de support et/ou d'entonnoir et apte à s'adapter à une variété de sacs de dimensions différentes.The present invention provides an extremely simple utensil playing the role of support and / or funnel and able to adapt to a variety of bags of different sizes.

Résumé de l'inventionSummary of the invention

On propose un ustensile pour le remplissage d'un sac souple, consiste un élément substantiellement en forme tronc de cône creux présentant une ouverture circulaire aux deux extrémités axiales, l'ouverture la moins large étant destinée à recevoir le produit lors du remplissage. La hauteur de l'ustensile est de préférence au moins deux fois inférieure à la hauteur du sac souple déployé. L'ustensile peut être muni de moyens de préhension pour l'utilisateur et/ou de moyens de fixation du bord de l'ouverture du sac. Selon un mode de réalisation préféré, la partie supérieure s'élargit pour former un entonnoir. Cette partie peut avantageusement être amovible. Lors du remplissage du sac, chaque fois que sa partie conique inférieure est remplie, l'ustensile est soulevé et redéposé sur le contenu du sac, réparti horizontalement par gravité.An utensil for filling a flexible bag is proposed, consisting of a substantially hollow truncated cone-shaped element having a circular opening at both axial ends, the narrower opening being intended to receive the product during filling. The height of the utensil is preferably at least two times smaller than the height of the expanded flexible bag. The utensil may be provided with gripping means for the user and / or means for fixing the edge of the opening of the bag. According to a preferred embodiment, the upper part widens to form a funnel. This part can advantageously be removable. When filling the bag, whenever its lower conical portion is filled, the utensil is lifted and redeposited on the contents of the bag, distributed horizontally by gravity.

Exposé plus détaillé de l'inventionMore detailed exposition of the invention

Selon un mode de réalisation, l'ustensile consiste en un tronc de cône droit creux présentant une ouverture aux deux extrémités axiales. Lors de l'utilisation de l'ustensile, l'ouverture inférieure est plus large que l'ouverture supérieure. Avantageusement celle-ci présentera des moyens de prise pour la manipulation, par exemple des poignées. On peut également prévoir de moyens de retenue ou de fixation des bords du sac, comme décrit ci-après.According to one embodiment, the utensil consists of a hollow right-hand cone having an opening at both axial ends. When using the utensil, the lower opening is wider than the upper opening. Advantageously it will present handling means for handling, by example of the handles. There may also be means for retaining or fixing the edges of the bag, as described below.

La partie supérieure peut éventuellement cependant s'élargir pour créer un effet d'entonnoir normal. Cette partie supérieure peut ainsi se présenter sous la forme d'un second segment de cone renversé accolé au premier par leurs petites bases. Ce second segment forme une collerette plus ou moins haute apte à, éventuellement mais pas obligatoirement, coopérer avec l'ouverture du sac et contenir sur le périmètre des moyens de fixation de l'extrémité ouverte du sac. La base du cône principal est de dimension inférieure à la section d'ouverture du sac et peut donc facilement s'y loger.The upper part may however widen to create a normal funnel effect. This upper part can thus be in the form of a second reversed cone segment attached to the first by their small bases. This second segment forms a collar more or less high capable of, possibly but not necessarily, cooperate with the opening of the bag and contain on the perimeter means for fixing the open end of the bag. The base of the main cone is smaller than the opening section of the bag and can therefore easily fit.

La hauteur de l'ustensile est de préférence une fraction seulement de la hauteur du sac une fois rempli. L'ustensile est donc relativement peu encombrant.The height of the utensil is preferably only a fraction of the height of the bag when filled. The utensil is relatively compact.

En effet, selon une caractéristique importante de l'invention, l'ustensile ou entonnoir peut être manuellement rehaussé par l'utilisateur au fur et à mesure que le sac se remplit en le soulevant, ensemble avec le bord supérieur du sac, et en le redéposant sur le contenu qui peut dès lors se "fluidiser" en quelque sorte sous la base généralement circulaire dudit entonnoir. Le sac se déploie dès lors en accordéon au fur et à mesure de son remplissage à travers l'ustensile-entonnoir.Indeed, according to an important feature of the invention, the utensil or funnel can be manually raised by the user as the bag fills by lifting, together with the upper edge of the bag, and by redepositing on the content which can then "fluidize" somehow under the generally circular base of said funnel. The bag then unfolds accordion as it is filled through the utensil-funnel.

On comprendra que, en fonction du contenu, un secouement du sac peut mais ne doit pas obligatoirement devoir être effectué.It will be understood that, depending on the content, a shake of the bag may but need not be performed.

Lors de son utilisation, la base de l'entonnoir est introduit à l'intérieur du sac. Il peut mais ne doit pas nécessairement être positionné de façon à ce que son ouverture supérieure épouse l'ouverture du sac. Des moyens de fixation connus en soi peuvent en effet être prévus mais la partie haute du sac peut aussi être affaisée ou être simplement repliée vers l'extérieur. La base de l'entonnoir est initialement en contact avec le fond du sac et donc à travers celui-ci est stable sur le sol. La paroi du sac ne dépasse pas la hauteur de l'ustensile et étant donné sa souplesse et sa dimension supérieure, comporte des plis sensiblement en accordéon.In use, the base of the funnel is introduced inside the bag. It can but does not have to be positioned so that its top opening fits the opening of the bag. Fastening means known per se may indeed be provided but the upper part of the bag may also be closed or simply folded outwards. The base of the funnel is initially in contact with the bottom of the bag and therefore through it is stable on the ground. The wall of the bag does not exceed the height of the utensil and given its flexibility and its superior size, has folds substantially accordion.

Selon une variante du procédé de remplissage, le sac est au début complètement aplati et ce n'est qu'après remplissage de l'entonnoir proprement dit que l'ouverture supérieure de celui-ci est maintenu ou solidarisé à l'ouverture du sac. L'entonnoir est alors soulevé pour permettre à son contenu de se répandre au fond du sac, puis replacé sur ce contenu. L'entonnoir est à nouveau rempli, soulevé et replacé et ainsi de suite jusqu'à ce que le sac soit plein.According to a variant of the filling process, the bag is initially completely flattened and it is only after filling the funnel proper that the upper opening thereof is held or secured to the opening of the bag. The funnel is then raised to allow its contents to spread at the bottom of the bag, and then placed on this content. The funnel is filled again, lifted and replaced and so on until the bag is full.

On comprendra que l'ustensile selon l'invention peut également servir de "mesure volumique" ou de dosage du contenu introduit dans le sac. En effet il sera soulevé et replacé sur le dit contenu à emballer, réparti par gravité, chaque fois qu'un certain volume a été introduit correspondant à son propre volume utile. Le volume d'un sac pourrait ainsi correspondre par exemple à 2, 3 , 4 ou 6 fois le volume de l'ustensile.It will be understood that the utensil according to the invention can also serve as "volume measurement" or dosage of the content introduced into the bag. Indeed it will be raised and placed on the said content to be packaged, distributed by gravity, whenever a certain volume has been introduced corresponding to its own useful volume. The volume of a bag could thus correspond for example to 2, 3, 4 or 6 times the volume of the utensil.

Selon un autre aspect de l'invention, l'ustensile comprend une collerette amovible. Cette dernière est solidarisée au corps principal par friction, encliquetage, un système à encoche ou de préference par vissage, par exemple à 1/4 de tour. D'autres moyens peuvent être utilisé, par exemple par utilisation de vis, ou un système à ergots s'engageant dans des entailles. Cette caractéristique d'amovibilité réversible rend l'objet de l'invention empilable en deux parties ce qui permet une réduction appréciable de l'encombrement.According to another aspect of the invention, the utensil comprises a removable collar. The latter is secured to the main body by friction, latching, a system with notch or preference by screwing, for example to 1/4 turn. Other means can be used, for example by using screws, or a pin system engaging in notches. This characteristic reversible removability makes the object of the invention stackable in two parts which allows an appreciable reduction in size.

Par ailleurs plusieurs collerettes différentes peuvent être associées à un même corps principal. L'utilisateur aura donc le choix en fonction des dimensions et du type de contenu du sac.Moreover, several different collars can be associated with the same main body. The user will have the choice depending on the size and type of content of the bag.

Selon un autre aspect de l'invention, la collerette est renforcée par rapport au reste de l'ustensile. Celle-ci, plus particulièrement au niveau du col, peut en effet être en contact violent avec le produit lors de son introduction dans le sac. Le renforcement peut être une épaisseur supplémentaire de plastique ou un renforcement métallique annulaire.According to another aspect of the invention, the flange is reinforced relative to the rest of the utensil. This, particularly at the neck, may indeed be in violent contact with the product when it is introduced into the bag. The reinforcement may be an additional thickness of plastic or an annular metal reinforcement.

On notera que l'invention procure d'autre avantages que le remplissage aisé d'un sac par étape successive de remplissage et soulèvement répétitif de l'ustensile.
Comme mentionné une seule personne est nécessaire pour le remplissage et celui-ci s'avère en conséquence moins dangereux, surtout lorsqu'un outil, tel une pelle, est utilisé. On a aussi constaté que l'effet de vide lors du retrait vertical de l'ustensile retient et absorbe la poussière en suspension provenant éventuellement du produit, par exemple dans la cas de gravats.It should be noted that the invention provides other advantages than the easy filling of a bag by successive step of filling and repetitive lifting of the utensil.
As mentioned only one person is needed for the filling and this is therefore less dangerous, especially when a tool, such as a shovel, is used. It has also been found that the vacuum effect during the vertical withdrawal of the utensil retains and absorbs dust in suspension possibly from the product, for example in the case of rubble.

L'invention sera davantage comprise à l'examen des dessins en annexe soumis à titre d'exemple uniquement, dans lesquels :

  • Les figs. 1a à 1c représentent en perspective un premier mode de réalisation de l'ustensile-entonnoir 1 sans et avec le sac correspondant.
  • Les figs. 2a à 2d illustrent une variante de l'entonnoir selon l'invention présentant une collerette courte
  • Les figs. 3a à 3d illustrent encore une variante de l'entonnoir selon l'invention présentant une collerette 3 plus large.
  • Les figs. 4 a-d illustrent en coupe verticale la technique de remplissage proprement dit d'un sac avec l'ustensile selon l'invention.
  • La fig.5 illustre une variante dans laquelle l'ouverture de la collerette 43 est asymétrique.
  • Les figs. 6 et 7 illustrent une autre variante de l'ustensile selon l'invention consistant en deux parties.
The invention will be further understood from the accompanying drawings, given by way of example only, in which:
  • The figs. 1a to 1c show in perspective a first embodiment of the funnel utensil 1 without and with the corresponding bag.
  • The figs. 2a to 2d illustrate a variant of the funnel according to the invention having a short collar
  • The figs. 3a to 3d still illustrate a variant of the funnel according to the invention having a wider flange 3.
  • The figs. 4 ad illustrate in vertical section the proper filling technique of a bag with the utensil according to the invention.
  • Fig.5 illustrates a variant in which the opening of the flange 43 is asymmetrical.
  • The figs. 6 and 7 illustrate another variant of the utensil according to the invention consisting of two parts.

Les figs. 1a et 1b sont deux vues, l'une d'en haut et l'autre d'en bas, en perspective d'un ustensile 1 selon l'invention sous la forme d'un cône droit tronqué exposant l'ouverture supérieure 19. La fig. 1c illustre le sac 2 adapté à l'ustensile 1 lors du remplissage du sac. On distingue un moyen 11 de préhension de l'ustensile, éventuellement ensemble avec le bord du sac 2 avec l'ustensile 1, pour l'utilisateur. Il peut s'agir d'une poignée 11 comme illustré par exemple formé ou moulé d'une pièce avec l'ustensile, apte à se rabattre par élasticité sur le bord du sac avec ou sans moyen de fixation en position rabattue (encliquetage). Une languette (non illustrée) peut être prévue d'origine flexible et rabattue par élasticité contre la face extérieure de l'ustensile pour pouvoir enserrer une partie du bord du sac. On comprendra qu'à aucun moment du remplissage, le contenu du sac lui-même ne doit être soulevé. ce ne sera le cas que pour l'ustensile et la paroi souple et libre du sac 2.The figs. 1a and 1b are two views, one from above and the other from below, in perspective of a utensil 1 according to the invention in the form of a truncated right cone exposing the upper opening 19. Fig. 1c illustrates the bag 2 adapted to the utensil 1 when filling the bag. There is a means 11 for gripping the utensil, possibly together with the edge of the bag 2 with the utensil 1, for the user. It may be a handle 11 as illustrated for example formed or molded in one piece with the utensil, able to fall back elastically on the edge of the bag with or without fastening means in the folded position (latching). A tongue (not shown) may be provided of flexible origin and folded by elasticity against the outer face of the utensil to be able to grip a portion of the edge of the bag. It will be understood that at no time during filling, the contents of the bag itself must not be lifted. this will only be the case for the utensil and the flexible and free wall of the bag 2.

Les figs. 2a à 2d illustrent de manièresimilaire une variante de l'entonnoir selon l'invention présentant une collerette 3 courte, par exemple d'environ 3 cm de hauteur pour une hauteur totale de 27 cm et un diamètre de 27 cm à la base de cette collerette.The figs. 2a to 2d illustrate similarly a variant of the funnel according to the invention having a short collar 3, for example about 3 cm high for a total height of 27 cm and a diameter of 27 cm at the base of this collar .

Les figs. 3a à 3d illustrent de manière similaire encore une variante de l'entonnoir selon l'invention présentant une collerette 3 longue d'environ 8 cm de hauteur pour une hauteur totale de 32 cm et un diamètre de 27 cm à la base de cette collerette. La largeur en projection, dans le plan horizontal, de la collerette est par exemple de 12 cm.The figs. 3a to 3d illustrate similarly still a variant of the funnel according to the invention having a flange 3 of about 8 cm in height for a total height of 32 cm and a diameter of 27 cm at the base of this collar. The projection width, in the horizontal plane, of the flange is for example 12 cm.

La fig. 4 illustre une variante dans laquelle l'ouverture de la collerette 43 est asymétrique, en l'occurence une demi-ouverture horizontale 40 et l'autre demi-ouverture 41 présentant un plan d'environ 30°. Cette configuration peut faciliter un chargement oblique ou même latéral.Fig. 4 illustrates a variant in which the opening of the flange 43 is asymmetrical, in this case a horizontal half-opening 40 and the other half-opening 41 having a plane of about 30 °. This configuration can facilitate oblique or even lateral loading.

On notera que la collerette 3 ou 43 facilite la préhension à deux mains de l'ustensile pour le soulever, le vider de son contenu et le redéposer sur le contenu ainsi vidé dans le sac.Note that the flange 3 or 43 facilitates the two-handed grip of the utensil to lift it, empty it of its contents and redeposit it on the contents thus emptied into the bag.

Les figs. 5 a-d illustrent en coupe verticale la technique de remplissage proprement dit du sac 2 avec l'ustensile 1, par exemple par des gravats 6. Au cours du remplissage l'ustensile est soulevé manuellement et ainsi vidé de son contenu chaque fois que son volume conique inférieur est plein, puis redéposé sur ce dernier pour être à nouveau rempli puis vidé par soulèvement ou retrait vertical. Le sac 52 est donc rempli par étapes, entre plusieurs retraits verticaux de l'ustensile.The figs. 5 ad illustrate in vertical section the proper filling technique of the bag 2 with the utensil 1, for example by rubble 6. During filling the utensil is lifted manually and thus emptied of its contents each time its conical volume lower is full, then redeposited on the latter to be filled again and emptied by uprising or vertical withdrawal. The bag 52 is filled in stages, between several vertical withdrawals of the utensil.

La fig. 6 illustre un ustensile dont la collerette 63 peut été enlevée de manière réversible. L'ustensile est formé ainsi de deux parties complémentaires séparables (61, 63). La collerette, représentée inversée par rapport au corps principal, comprend une courte section cylindrique 65 munies de 4 ergots 66 s'étendant radialement vers l'extérieur. Ces ergots peuvent s'engager et être bloqués dans des entailles 67 correspondantes prévues au pourtour de l'ouverture la plus petite du corps conique 61 formant la base l'ustensile.Fig. 6 illustrates a utensil whose flange 63 can be removed reversibly. The utensil is thus formed of two separable complementary parts (61, 63).
