Description

POIGNEE RAPPORTEE SUR EMBALLAGE, SON PROCEDE DE FABRICATION ET LES MOYENS POUR LA MISE EN OEUVRE DE CE PROCEDE HANDLE ADDED TO PACKAGING, ITS MANUFACTURING PROCESS AND THE MEANS FOR CARRYING OUT SAID METHOD
La présente invention concerne une poignée rapportée sur embal- lage, son procédé de fabrication et les moyens pour la mise en oeuvre de ce procédé.The present invention relates to a handle attached to packaging, its manufacturing process and the means for implementing this process.
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 conférantt 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'embal¬ lage. Chaque patte est donc normalement perpendiculaire au plan ' de la lanière constituant le corps de poignée mais, préalablement à son engage- ment 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 packaging or the like with molded or injected plastic handles. The handles generally comprise a body or central 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-profile and intended to be engaged from the outside. , in a slot made for this purpose in the wall of the packaging. Each tab is therefore normally perpendicular to the plane ' of the strap constituting the handle body but, prior to its engagement in the slot intended for it, it is tilted by approximately 90 ° so that one of its ends is applied against the handle body.
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. La présente invention vise à remédier à ces inconvénients. A cet effet, dans la poignée qu'elle concerne et qui est du type précité dont chaque extrémité est équipée d'un organe d'accrochage, le corps de poignée est cintré de manière que ses extrémités soient séparées l'une de l'autre d'une distance égale à celle séparant les fentes prévues dans la paroi de l'emballage auquel elle est destinée.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. The present invention aims to remedy these drawbacks. To this end, in the handle which it concerns and which is of the aforementioned type, each end of which is fitted with a hooking member, the handle body is bent so that its ends are separated from one another. by a distance equal to that separating the slots provided in the wall of the packaging for which it is intended.
Suivant une forme d'exécution simple de l'invention, chaque patte d'accrochage prévue à chaque extrémité du corps est plane et cette poignée est moulée de manière que chacune de ses pattes forme, avec l'extrémité correspondante du corps, un angle aigu et, de préférence, de manière à être parallèle à la patte d'accrochage située à l'autre extrémité du ''corps et au plan de symétrie de la poignée.According to a simple embodiment of the invention, each hooking tab provided at each end of the body is planar and this handle is molded so that each of its tabs forms, with the corresponding end of the body, an acute angle and preferably so as to be parallel to the hooking tab located at the other end of the body and to the plane of symmetry of the handle.
Ainsi, chaque poignée peut être mise en place automatiquement puisque, naturellement, ses deux pattes ont le même intervalle que les fentes prévues pour les recevoir dans la paroi de l'emballage.Thus, each handle can be placed automatically since, of course, its two legs have the same interval as the slots provided for receiving them in the wall of the package.
Pour faciliter encore la mise en place automatique de ces poignées, suivant une autre 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 sectionnabies.To further facilitate the automatic positioning of these handles, according to another 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 material which are easily sectioned .
Cette disposition présente l'avantage de faciliter considérablement l'alimentation des machines prévues pour leur mise en place. Suivant une variante d'exécution de l'invention, chaque patte d'accrochage est conformée de manière à présenter une section transversale en V dont le plan bissecteur est sensiblement 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 provided for their installation. According to an alternative embodiment of the invention, each attachment tab is shaped so as to have a V-shaped cross section whose bisecting plane is substantially 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 sectionnabies 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 sectioned during placing a handle on a package.
Il faut noter que ce ruban, après prédécoupe des poignées, peut être facilement enroulé, ce qui facilite considérablement le transport et le stockage de ces poignées.It should be noted that this ribbon, after pre-cutting the handles, can be easily wound up, 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 : Figure 1 est une vue en perspective d'une première forme 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 is a view in perspective of a first embodiment of this handle;
Figure 2 est une vue en perspective illustrant son procédé de fabrication et de mise en place ;Figure 2 is a perspective view illustrating its manufacturing process and implementation;
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 • est une vue en perspective similaire à figure 1, montrant une variante d'exécution de cette poignée ;Figure • is a perspective view similar to Figure 1, showing an alternative embodiment of this handle;
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 le mode de fabrication de la poignée de figure <_-. La poignée 2 selon l'invention est du type comportant un corps central 3 en forme de lanière semi-rigide équipé, à chacune de ses extré¬ mités, d'une patte d'accrochage , l'ensemble étant réalisé en matière plastique telle qu'un PVC ou autre similaire. Selon l'invention, 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 L. sensiblement égale à la distance L- 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 <_-. II 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 au même écartement que les fentes 5. Dans l'exemple illustré sur la figure 1, chaque patte d'accrochageFigure 7 is a perspective view similar to Figure 2, illustrating the method of manufacturing the handle figure <_-. The handle 2 according to the invention 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 lug, the assembly being made of plastic material such that 'a PVC or similar. According to the invention, 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 L. substantially equal to the distance L- separating the slots 5 formed in the wall 6 of the package for which this handle 2 is intended, to allow its mooring. using the hooking lugs <_-. It follows that, thanks to this arrangement, each handle 2 may be made without constraint au * above the wall 6 of the packaging and its lugs engaged in the slots 5 of the wall 6 without the need to take special measures to bring the mooring lugs to the same spacing as the slots 5. In the example illustrated in Figure 1, each latching lug
•_- est constituée par une plaquette sensiblement ovale et cette poignée 2 est moulée de manière que le plan médian a de chaque patte 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'une angle arrondi 3b de telle sorte que chaque patte 4 fait, avec le brin correspondant du corps 3, un même angle aigu 8.• _- consists of a substantially oval plate and this handle 2 is molded so that the median plane a of each leg is parallel to the plane 4a of the other leg 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 each tab 4 forms, 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 3 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. La mise en place des poignées 2 sur les emballages destinés à les recevoir est considérablement améliorée si 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 manière, 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.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 include 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 package 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 package, au- above the slots 5 of the latter, by two pushers 11 with alternating vertical movement, these pushers 11 causing the engagement of the lugs 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 3 of the handle 2, tends to tilt the tabs 4 in the ens of arrows 12, which has the effect, as soon as an effort of traction directed in the direction of the arrow 13 is exerted on the body 3 of the handle 2 considered, to bring them in a plane parallel to the wall 6. The positioning of the handles 2 on the packages intended to receive them is considerably improved if each handle 2, instead of being molded individually, is molded into strips, each of which comprises a plurality of handles 2 linked to each other by bridges of material 14 and 15. In this way, each handle 2 is easily guided by the guide support 9 of the positioning machine. In this case, the means for setting up the handles 2 include, • 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 FIG. 3, each blade 16 is linked to its support 17, integral with the 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 bissecteurFIG. 4 shows an alternative embodiment 2 ′ of this handle, a variant in which each hooking tab 4 ′ which equips each end of its body 3 ′ is shaped so as to have a cross section in V, the bisector plane 4 is parallel to the bisector plane
4'a de l'autre patte d'accrochage 4' et parallèle aussi au plan de symétrie 7' de cette poignée 2'.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'ecartement L' , entre ses pattes d'accrochage 4' soit sensiblement égal à l'ecartement L_ 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 ′, between its hooking lugs 4 ′ is substantially equal to the spacing L_ of the slots 5 formed 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 completely 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'amar¬ rage, 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'ecartement 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. 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 conformée au profil du ruban extrudé pour réaliser la découpe des poignées 2' ou mieux encore, une prédécoupe laissant susbister, comme dans l'exemple précédent, des ponts de matière 14' et 15' entre chaque poignée 2' et celles qui l'encadrent. Ce procédé de fabrication permet donc d'abaisser considérable¬ ment 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 prédécoupe.This variant embodiment of handles 2 ′ has the advantage that the presence of the pushers is not used to ensure the amar¬ rage, on the internal face of the wall 6 of the packaging, of the tabs 4 'hooking. The elasticity of the material constituting the lugs and form 'given to them enough to obtain this result. For this, the spacing between the free edges of the fastening tabs 4 'must be, in the absence of any stress, greater than the width of the slots 5 but must also be able to be reduced, by elastic deformation, to a value less than this width. As appears from the examination of Figure 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 conformed to the profile of the extruded ribbon to cut the handles 2 ′ or better still, a precut allowing susbister, as in the previous example, material bridges 14 'and 15' between each handle 2 'and those which surround it. 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 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.
