Abstract
Description
La p-Esente invention a trait aux sacs constitués par une poche en matière plastique, généralement pourvue de soufflets latéraux et dont le portage est réalisé par l'intermEdiaire de poignées obtenues par découpage de deux ouvertures pratiquées en vis-a-vis à une courte distance au-dessous de la partie supérieure ouverte. The p-Esente invention relates to bags consisting of a plastic bag, generally provided with side gussets and the porting of which is carried out by means of handles obtained by cutting two openings made opposite a short distance below the open top.
Ces sacs à poignées découpées presenteot des avantages indiscutables au niveau du prix de revient du fait que la réalisation des poignes ne ncessite aucune pièce rapportée. Toutefois, ils comportent un inconvénient sensible, au moins lorsqu'ils renferment un article relativement lourd ; en pareil ces effectivement, les ouvertures de portage se déforment sous l'effet du poids, exercent un cisaillement douloureux dans le creux de la main de l'usager, et parviennent même a se déchirer brusquement en provoquant la chute du contenu sur le sol. These bags with cut handles present indisputable advantages in terms of cost price because the production of the handles does not require any attachments. However, they have a significant drawback, at least when they contain a relatively heavy article; in like these effectively, the carrying openings are deformed under the effect of the weight, exert a painful shearing in the hollow of the hand of the user, and even manage to tear suddenly by causing the fall of the contents on the ground.
C'est à cet inconvénient que la présente invention entend principalement remédier. It is to this drawback that the present invention mainly intends to remedy.
Conformément à l'invention, on introduit à l'intérieur de la partie supérieure ouverte de la poche deux barrettes semi-rigides d'armature qu'on fixe par soudage ou collage au niveau du bord supérieur de l'une et l'autre paroi de ladite poche, on fait subir 3 celle-ei deux retournements ou replis successifs et l'on fixe l'enroulement obtenu par une seconde ligne de soudage ou collage. According to the invention, two semi-rigid reinforcing bars are inserted inside the open upper part of the pocket, which are fixed by welding or gluing at the upper edge of one and the other wall. of said pocket, it is subjected to 3 this ei two successive turns or folds and the winding obtained is fixed by a second welding or bonding line.
On conçoit que si la hauteur séparant le bord supérieur de chaque ouverture ou poignée et le bord supérieur de chaque paroi est convenablement calculée, chacune des barrettes d'armature vient se disposer immEdiatement au-dessus de l'ouverture correspondante en raidissant et armant la partie ouverte de la poche tout en offrant un meilleur confort à la main de l'usager. It is understood that if the height separating the upper edge of each opening or handle and the upper edge of each wall is suitably calculated, each of the reinforcing bars comes to be placed immediately above the corresponding opening by stiffening and fitting the part open from the pocket while offering better comfort to the user's hand.
te dessin annexé, donné a titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques quelle pressente et les avantages qu'elle est susceptible de procurer
Fig. 1 est une vue en perspective montrant une poche et deux barrettes d'armature pour la rbalisation d'un sac conformement a la présente invention.the attached drawing, given by way of example, will make it possible to better understand the invention, the characteristics which it presents and the advantages which it is likely to provide.
Fig. 1 is a perspective view showing a pocket and two reinforcing bars for reworking a bag in accordance with the present invention.
Fig. 2 montre de la même manière le sac obtenu. Fig. 2 shows the same bag obtained.
Fig. 3 à 6 illustrent schEmatiquement les phases du procéda de rtalisation. Fig. 3 to 6 schematically illustrate the phases of the implementation process.
En fig. 1, la référence 1 design une poche en matière plastique obtenue par découpage et soudage d'une longueur appropriée d'un tube réalisé par extrusion. Cette poche 1 est en fait formée par deux parois verticales 2 reliées l'une a l'autre par deux soufflets latéraux 3 et une ligne de soudage au niveau du fond fermez 4. A la façon usuelle, chaque paroi 2 est decoupee d'une ouverture 5 destinée à permettre le passage de la main afin de former poignée de portage, étant toutefois observE que ces deux ouvertures 5 sont ici ménagées a une hauteur du bord libre des parois 2 plus grande que dans la fabrication classique. In fig. 1, the reference 1 design a plastic bag obtained by cutting and welding an appropriate length of a tube produced by extrusion. This pocket 1 is in fact formed by two vertical walls 2 connected to one another by two lateral bellows 3 and a welding line at the bottom close 4. In the usual way, each wall 2 is cut out with a opening 5 intended to allow the passage of the hand in order to form a carrying handle, being however observed that these two openings 5 are here formed at a height of the free edge of the walls 2 greater than in conventional manufacturing.
Afin d'obtenir le sac fini représente en fig. 2, on commence par introduire dans la poche 1 deux barrettes semi-rigides 6, en carton ou en matière synthetique. Comme montre en fig. 3, chacune de ces barrettes présente une hauteur sensible de façon a comporter une grande rigidité sur chant en dépit de sa faible épaisseur ; chaque barrette 6 est établie une longueur substantiellement égale à celle de la poche 1 en vue de s'étendre pratiquement le long de tout le bord supérieur libre de chaque paroi 2. Chaque barrette est fixée au bord de sa paroi 2 par une ligne horizontale de soudage ou collage référencée 7 en fig. 4. In order to obtain the finished bag shown in fig. 2, we begin by introducing into the pocket 1 two semi-rigid bars 6, made of cardboard or synthetic material. As shown in fig. 3, each of these bars has a substantial height so as to have great rigidity on edge despite its small thickness; each bar 6 is established a length substantially equal to that of the pocket 1 in order to extend practically along the entire free upper edge of each wall 2. Each bar is fixed to the edge of its wall 2 by a horizontal line of welding or bonding referenced 7 in fig. 4.
Ceci fait, on fait tourner deux fois sur elle-même chaque barrette 6 de façon à enrouler autour des deux barrettes la partie supérieure ouverte de la poche 1. Fig. 5 et 6 font bien apparaître ces deux retournements successifs, l'enroulement obtenu au niveau de chaque barrette 6 entant fixe en place par une ligne horizontale de soudage 8 opérée à l'exterieur de chaque paroi 2. This done, each bar 6 is rotated twice on itself so as to wind around the two bars the open upper part of the bag 1. FIG. 5 and 6 clearly show these two successive reversals, the winding obtained at the level of each bar 6 coming fixed in place by a horizontal welding line 8 operated outside each wall 2.
On comprend que les deux barrettes 6 se trouvent de la sorte enveloppées dans la partie supérieure repliée de la poche 1 ; les choses sont prévues de façon à ce que leur bord inférieur vienne se disposer immédiatement au-dessus du bord supérieur de l'ouverture 5 correspondante, si bien que non seulement la partie supérieure du sac, raidie et armée par lesdites barrettes, est à l'abri de tout risque de déchirure intempestive quel que soit le poids du contenu, mais également les deux poignées offrent pour l'utilisateur un confort bien supérieur a celui habituel, par suite justement de la présence des barrettes et de l'enroulement de matière plastique qui les renferme. It is understood that the two bars 6 are thus wrapped in the folded upper part of the pocket 1; things are provided so that their lower edge comes to be placed immediately above the upper edge of the corresponding opening 5, so that not only the upper part of the bag, stiffened and armed by said bars, is at l sheltered from any risk of untimely tearing regardless of the weight of the contents, but also the two handles offer the user much greater comfort than usual, precisely because of the presence of the bars and the plastic wrapping which contains them.
I1 va de soi que le profil des ouvertures 5 peut être quelconque pour autant qu'il permette le passage de la main. De la même manière, la largeur ou hauteur des barrettes 6 peut varier dans une large mesure, en fonction du poids des articles destinés à être transportes. It goes without saying that the profile of the openings 5 can be arbitrary provided that it allows the passage of the hand. Likewise, the width or height of the bars 6 can vary to a large extent, depending on the weight of the articles intended to be transported.
I1 doit d'ailleurs être entendu que la description qui procède n'a ete donnée qu'a titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les dÉtails d'execution décrits par tous autres équivalents. It should moreover be understood that the description which proceeds has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
