Description

La présente invention concerne une poignée rapportée sur emballage, et les moyens de mise en place sur un emballage.The present invention relates to a handle attached to packaging, and the means of positioning on a packaging.

Il est courant d'équiper des emballages en carton ou similaire de poignées en matière plastique moulée ou injectée. Les poignées comprennent généralement un corps ou partie centrale en forme de lanière muni, à chacune de ses extrémités, d'une patte d'accrochage conférant à chaque extrémité de cette poignée un profil en T et destinée à être engagée, depuis l'extérieur, dans une fente ménagée, à cet effet, dans la paroi de l'emballage. Chaque patte est donc normalement perpendiculaire au plan de la lanière constituant le corps de poignée mais, préalablement à son engagement dans la fente qui lui est destinée, elle est basculée d'environ 90° de manière que l'une de ses extrémités soit appliquée contre le corps de poignée.It is common to equip cardboard or similar packaging with molded or injected plastic handles. The handles generally comprise a central body or part in the form of a strap provided, at each of its ends, with a hooking tab giving each end of this handle a T-shaped profile and intended to be engaged from the outside, in a slot made for this purpose in the wall of the package. Each tab is therefore normally perpendicular to the plane of the strap constituting the handle body but, prior to its engagement in the slot which is intended for it, it is tilted by approximately 90 ° so that one of its ends is applied against the handle body.

Le brevet US-A-4 176 423, par exemple, décrit des poignées en matière plastique fabriquées à partir d'un ruban (ou bande) moulé par extrusion, ayant en coupe le profil longitudinal des poignées et prédécoupé transversalement à intervalles réguliers pour y définir les poignées, chaque prédécoupe laissant subsister entre les poignées des ponts de liaison sectionnables.US-A-4,176,423, for example, describes plastic handles made from an extrusion molded tape (or strip), having in section the longitudinal profile of the handles and precut transversely at regular intervals to define the handles, each pre-cut leaving between the handles of the sectionable connecting bridges.

Par ailleurs, pour permettre la préhension de la poignée par l'utilisateur et le passage de sa main entre la poignée et la paroi de l'emballage, la distance séparant les fentes prévues dans la paroi de l'emballage pour le passage et l'amarrage des pattes d'accrochage de la poignée est inférieure à la longueur du corps de poignée qui, de ce fait, doit être partiellement cintré avant engagement des pattes dans les fentes. On conçoit que cette opération est difficile à réaliser automatiquement.Furthermore, to allow the grip of the handle by the user and the passage of his hand between the handle and the wall of the package, the distance separating the slots provided in the wall of the package for the passage and the mooring of the grip lugs is less than the length of the handle body which, therefore, must be partially bent before engagement of the lugs in the slots. It is understood that this operation is difficult to perform automatically.

La présente invention vise à remédier à ces inconvénients. A cet effet, des poignées sont réalisées telles que définies dans la revendication 1 divisée en deux parties à l'égard de US-A-4 176 423.The present invention aims to remedy these drawbacks. For this purpose, handles are produced as defined in claim 1 divided into two parts with regard to US-A-4 176 423.

Pour faciliter la mise en place automatique de ces poignées, suivant une caractéristique intéressante de l'invention, ces poignées sont moulées, injectées en bandes dont chacune est constituée par une pluralité de poignées assemblées côte à côte par des ponts de matière facilement sectionnables.To facilitate the automatic positioning of these handles, according to an advantageous characteristic of the invention, these handles are molded, injected in strips, each of which is constituted by a plurality of handles assembled side by side by bridges of easily sectionable material.

Cette disposition présente l'avantage de faciliter considérablement l'alimentation des machines ou moyens prévus pour leur mise en place, tels que définis dans les revendications 2 à 5. Suivant l'invention, chaque patte d'accrochage est conformée de manière à présenter une section transversale en V dont le plan bissecteur est parallèle à celui de l'autre patte et au plan de symétrie de la poignée.This arrangement has the advantage of considerably facilitating the feeding of the machines or means provided for their installation, as defined in claims 2 to 5. According to the invention, each hooking lug is shaped so as to present a cross section in V whose bisecting plane is parallel to that of the other tab and to the plane of symmetry of the handle.

Dans ce cas, ces poignées peuvent être fabriquées par extrusion, en un ruban continu et elles peuvent être prédécoupées dans ce ruban, de manière à laisser subsister entre chacune d'elles et celles qui lui sont adjacentes, des ponts de matière facilement sectionnables lors de la mise en place d'une poignée sur un emballage.In this case, these handles can be manufactured by extrusion, in a continuous ribbon and they can be precut in this ribbon, so as to leave between each of them and those adjacent to it, bridges of material easily sectionable during placing a handle on a package.

Il faut noter que ce ruban, après prédécoupé des poignées, peut être facilement enroulé, ce qui facilite considérablement le transport et le stockage de ces poignées.It should be noted that this tape, after pre-cut handles, can be easily wound, which considerably facilitates the transport and storage of these handles.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemples non limitatifs, deux formes d'exécution de cette poignée :In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended schematic drawing representing, by way of nonlimiting examples, two embodiments of this handle:

Figure 1 est une vue en perspective d'une première forme d'exécution d'une poignée ne faisant pas partie de l'invention.Figure 1 is a perspective view of a first embodiment of a handle not forming part of the invention.

Figure 2 est une vue en perspective illustrant son procédé de mise en place.Figure 2 is a perspective view illustrating its implementation process.

Figure 3 est une vue de face en élévation montrant les moyens pour la mise en place de cette poignée.Figure 3 is a front elevational view showing the means for the establishment of this handle.

Figure 4 est une vue en perspective similaire à figure 1, montrant une variante d'exécution de cette poignée, conforme à l'invention.Figure 4 is a perspective view similar to Figure 1, showing an alternative embodiment of this handle, according to the invention.

Figures 5 et 6 sont, à échelle agrandie, des vues illustrant le mode d'amarrage de cette poignée à la paroi de l'emballage auquel elle est destinée.Figures 5 and 6 are, on an enlarged scale, views illustrating the method of securing this handle to the wall of the package for which it is intended.

Figure 7 est une vue en perspective similaire à figure 2, illustrant la poignée de figure 4 après la fabrication.Figure 7 is a perspective view similar to Figure 2, illustrating the handle of Figure 4 after manufacture.

La poignée 2 est du type comportant un corps central 3 en forme de lanière semi-rigide équipé, à chacune de ses extrémités, d'une patte d'accrochage 4, l'ensemble étant réalisé en matière plastique tel qu'un PVC ou autre similaire.The handle 2 is of the type comprising a central body 3 in the form of a semi-rigid strap equipped, at each of its ends, with a hooking tab 4, the assembly being made of plastic material such as PVC or other similar.

Le corps 3 de cette poignée est cintré de manière que les extrémités 3a de son corps 3 soient séparées l'une de l'autre d'une distance L₁ sensiblement égale à la distance L₂ séparant les fentes 5 ménagées dans la paroi 6 de l'emballage auquel est destinée cette poignée 2, pour permettre son amarrage à l'aide des pattes d'accrochage 4. Il en résulte que, grâce à cette disposition, chaque poignée 2 peut être présentée sans contrainte au-dessus de la paroi 6 de l'emballage et ses pattes engagées dans les fentes 5 de cette paroi 6 sans qu'il soit nécessaire de prendre des mesures particulières pour amener les pattes d'amarrage 4 au même écartement que les fentes 5.The body 3 of this handle is curved so that the ends 3a of its body 3 are separated from each other by a distance L₁ substantially equal to the distance L₂ separating the slots 5 formed in the wall 6 of the packaging for which this handle 2 is intended, to allow it to be moored with the hooking tabs 4. As a result, thanks to this arrangement, each handle 2 can be presented without constraint above the wall 6 of the packaging and its legs engaged in the slots 5 of this wall 6 without it being necessary to take special measures to bring the mooring legs 4 to the same spacing as the slots 5.

Dans l'exemple illustré sur la figure 1, chaque patte d'accrochage 4 est constituée par une plaquette sensiblement ovale et cette poignée 2 est moulée de manière que le plan médian 4a de chaque patte 4 soit parallèle au plan 4a de l'autre patte 4 ainsi qu'au plan de symétrie 7 de la poignée 2. Dans cet exemple, le corps 3 de la poignée 2 est cintré par réalisation, dans sa partie médiane, d'un angle arrondi 3b de telles sorte que chaque patte 4 fait, avec le brin correspondant du corps 3, un même angle aigu 8.In the example illustrated in FIG. 1, each attachment tab 4 is constituted by a substantially oval plate and this handle 2 is molded so that the median plane 4a of each tab 4 is parallel to the plane 4a of the other tab 4 as well as to the plane of symmetry 7 of the handle 2. In this example, the body 3 of the handle 2 is bent by making, in its middle part, a rounded angle 3b so that that each leg 4 makes, with the corresponding strand of the body 3, the same acute angle 8.

La figure 3 illustre les moyens pour la mise en place d'une poignée 2 par engagement de ses pattes d'accrochage 4 dans les fentes 5 de la paroi 6 d'un emballage. Ces moyens comprennent un support-guide 9 ou goulotte d'alimentation, cintré au profil de la poignée 2, disposé au-dessus de l'emballage à équiper de cette poignée et de manière que son extrémité aval soit décalée horizontalement par rapport aux fentes 5 de cet emballage dans le sens opposé au déplacement des poignées 2 sur ce guide 9. Chaque poignée 2, qui dépasse l'extrémité aval du support-guide 9, est alors déplacée transversalement, en direction de la paroi 6 de cet emballage, au-dessus des fentes 5 de ce dernier, par deux poussoirs 11 à déplacement vertical alternatif, ces poussoirs 11 provoquant l'engagement des pattes d'accrochage 4 dans les dites fentes jusqu'à ce qu'elles soient totalement engagées au-delà de la paroi 6. On conçoit aisément que la présence des poussoirs 11, dont chacun agit dans l'un des angles 8 formés par la liaison entre une patte d'accrochage 4 et le corps de la poignée 2, a tendance à faire basculer les pattes 4 dans le sens des flèches 12, ce qui a pour effet, dès qu'un effort de traction dirigé dans le sens de la flèche 13 est exercé sur le corps 3 de la poignée 2 considérée, de les amener dans un plan parallèle à la paroi 6.Figure 3 illustrates the means for the establishment of a handle 2 by engagement of its hooking lugs 4 in the slots 5 of the wall 6 of a package. These means comprise a guide support 9 or feed chute, curved to the profile of the handle 2, disposed above the packaging to be fitted with this handle and so that its downstream end is offset horizontally relative to the slots 5 of this packaging in the opposite direction to the movement of the handles 2 on this guide 9. Each handle 2, which exceeds the downstream end of the guide support 9, is then moved transversely, in the direction of the wall 6 of this packaging, au- above the slots 5 of the latter, by two pushers 11 with alternating vertical movement, these pushers 11 causing the engagement of the latching tabs 4 in the said slots until they are fully engaged beyond the wall 6. It is easy to see that the presence of the pushers 11, each of which acts in one of the angles 8 formed by the connection between a latching tab 4 and the body of the handle 2, tends to tilt the tabs 4 into the sen s arrows 12, which has the effect, as soon as a tensile force directed in the direction of arrow 13 is exerted on the body 3 of the handle 2 considered, to bring them into a plane parallel to the wall 6.

La mise en place des poignées 2 sur les emballages destinés à les recevoir est considérablement améliorée sur chaque poignée 2, au lieu d'être moulée isolément, est moulée en bandes dont chacune comporte une pluralité de poignées 2 liées les unes aux autres par des ponts de matière 14 et 15. De cette matière, chaque poignée 2 est guidée facilement par le support-guide 9 de la machine de mise en place. Dans ce cas, les moyens pour la mise en place des poignées 2 comprennent, en plus du support-guide 9 et des poussoirs 11, des lames 16 dont chacune est parallèle à l'un des brins du corps 3 de la poignée 2, juste en aval de l'extrémité du support-guide 9, de manière que chacune d'elles joue le rôle de lame de cisaillement des ponts de matière 14 et 15, tandis que l'extrémité considérée du support-guide 9 joue le rôle de contre-lame. Avantageusement et comme montré sur la figure 3, chaque lame 16 est liée à son support 17, solidaire des poussoirs 11, par des moyens élastiques tels que des ressorts 18.The positioning of the handles 2 on the packages intended to receive them is considerably improved on each handle 2, instead of being molded in isolation, is molded into strips, each of which comprises a plurality of handles 2 linked to each other by bridges of material 14 and 15. From this material, each handle 2 is easily guided by the guide support 9 of the positioning machine. In this case, the means for fitting the handles 2 comprise, in addition to the guide support 9 and the pushers 11, blades 16 each of which is parallel to one of the strands of the body 3 of the handle 2, just downstream of the end of the guide support 9, so that each of them plays the role of shear blade of the material bridges 14 and 15, while the considered end of the guide support 9 plays the role of counter -blade. Advantageously and as shown in Figure 3, each blade 16 is linked to its support 17, integral pushers 11, by elastic means such as springs 18.

La figure 4 montre une variante d'exécution 2′ de cette poignée, variante dans laquelle chaque patte d'accrochage 4′ qui équipe chaque extrémité de son corps 3′ est conformée de manière à présenter une section transversale en V dont le plan bissecteur 4′a est parallèle au plan bissecteur 4′a de l'autre patte d'accrochage 4′ et parallèle aussi au plan de symétrie 7′ de cette poignée 2′.Figure 4 shows an alternative embodiment 2 ′ of this handle, a variant in which each hooking lug 4 ′ which equips each end of its body 3 ′ is shaped so as to have a V-shaped cross section whose bisecting plane 4 ′ A is parallel to the bisector plane 4′a of the other hooking tab 4 ′ and also parallel to the plane of symmetry 7 ′ of this handle 2 ′.

Comme dans l'exemple précédent, cette poignée 2′ est fabriquée de manière que son corps 3′ soit cintré afin que l'écartement L′₁ entre ses pattes d'acrochage 4′ soit sensiblement égal à l'écartement L₂ des fentes 5 ménagées dans la paroi 6 de l'emballage devant être équipé de cette poignée 2′.As in the previous example, this handle 2 ′ is manufactured so that its body 3 ′ is curved so that the spacing L′₁ between its fastening tabs 4 ′ is substantially equal to the spacing L₂ of the slots 5 provided in the wall 6 of the package to be equipped with this handle 2 ′.

La mise en place de cette poignée 2' est réalisée sensiblement de la même manière que celle de la poignée 2 précédemment décrite et avec des moyens tout à fait comparables comportant des poussoirs 11. Cette mise en place est d'ailleurs illustrée par les figures 5 et 6.The positioning of this handle 2 ′ is carried out substantially in the same way as that of the handle 2 described above and with entirely comparable means comprising pushers 11. This positioning is moreover illustrated by FIGS. 5 and 6.

Cette variante d'exécution de poignées 2′ présente l'avantage que la présence des poussoirs n'est pas mise à contribution pour assurer l'amarrage, à la face interne de la paroi 6 de l'emballage, des pattes d'accrochage 4′. L'élasticité de la matière constituant ces pattes et la forme qui leur est donnée suffit à l'obtention de ce résultat. Pour cela, l'écartement entre les bords libres des pattes d'accrochage 4′ doit être, en l'absence de toute contrainte, supérieur à la largeur des fentes 5 mais doit aussi pouvoir être réduit, par déformation élastique, à une valeur inférieure à cette largeur.This alternative embodiment of handles 2 ′ has the advantage that the presence of the pushers is not used to ensure the mooring, on the internal face of the wall 6 of the packaging, of the latching tabs 4 ′. The elasticity of the material constituting these legs and the shape which is given to them is sufficient to obtain this result. For this, the spacing between the free edges of the fastening tabs 4 ′ must, in the absence of any constraint, be greater than the width of the slots 5 but must also be able to be reduced, by elastic deformation, to a lower value to this width.

Comme cela ressort de l'examen de la figure 7, la forme conférée à cette poignée 2′ rend possible sa fabrication par extrusion. Il suffit alors de prévoir, à la sortie de la filière d'extrusion, une lame éventuellement portée par un cylindre rotatif et conforme au profil du ruban extrudé pour réaliser la découpe des poignées 2′ ou mieux encore, une prédécoupé laissant subsister, comme dans l'exemple précédent, des ponts de matière 14′ et 15′ entre chaque poignée 2′ et celles qui l'encadrent.As appears from the examination of FIG. 7, the shape given to this handle 2 ′ makes it possible to manufacture it by extrusion. It then suffices to provide, at the outlet of the extrusion die, a blade possibly carried by a rotary cylinder and conforming to the profile of the extruded ribbon to cut the handles 2 ′ or better still, a pre-cut allowing to remain, as in the previous example, material bridges 14 ′ and 15 ′ between each handle 2 ′ and those which surround it.

Ce procédé de fabrication permet donc d'abaisser considérablement le prix de revient de ces poignées 2′ puisqu'elles peuvent être fabriquées en continu et, éventuellement, stockées et expédiées après avoir été mises en rouleau après la prédécoupé.This manufacturing process therefore makes it possible to considerably lower the cost price of these handles 2 ′ since they can be manufactured continuously and, optionally, stored and shipped after being rolled up after the precut.

Lors de leur mise en place, il sera possible d'utiliser des moyens tout à fait similaires à ceux destinés à la mise en place de la poignée de figure 1, tels qu'illustrés sur la figure 3.When they are put in place, it will be possible to use means quite similar to those intended for putting the handle of FIG. 1 in place, as illustrated in FIG. 3.
