SACS NOTAMM}:NT A PAINS THERMOSOUDES NOTAMM} BAGS: NT WITH THERMOSOUDED BREADS
ENTRE EUX ET PROCEDE DE REALISATIONBETWEEN THEM AND IMPLEMENTATION METHOD
La presente invention a pour objet un ensemble de sacs, confectionnes au moins en partie en polypropylene - essentiellement destines a recevoir le pain -, thermosoudes entre eux, et son procede de realisation. C et ensemble peut etre utilis e en p articulier, sur le s distributeurs de sacs a pains couramment utilises dans le commerce du pain. A l'heure actuelle, vent le plus souvent utilises sur les points de vente de pains, des sacs independents les uns des autres, fan's de The present invention relates to a set of bags, made at least in part of polypropylene - essentially intended to receive the bread -, heat-sealed together, and its production process. This set can be used in particular on the bread bag dispensers commonly used in the bread trade. At present, most often used at the point of sale of breads, bags independent of each other, fans of
materiaux divers, mais il n'existe pas d'ensembles de sacs pre- various materials, but there are no sets of pre-
assembles, reunis par leur partie superieure grace aux qualites particulieres du polypropylene chauffe, et munis d'une pre-decoupe afin assembled, united by their upper part thanks to the special qualities of heated polypropylene, and provided with a pre-cut so
d'en faciliter l'arrachage.to facilitate the uprooting.
L'utilisation du produit selon la presente invention presente de nombreuxavantages: - d'un seul geste, il est possible de positionner sur le distributeur de sacs, un nombre important de sacs, - l'operation de mise en sac du pain se trouve facilitee et securisee en raison de la solidite et d'une certaine rigidite obtenues par la reunion entre elles des parties superieures des sacs, - chaque sac se detache facilement du suivant, - l'utilisation de cet ensemble permet un gain de temps incontestable, assure une plus grande hygiene du fait de la reduction, a la fois, du nombre de manipulations necessaires et du risque The use of the product according to the present invention has many advantages: - with a single gesture, it is possible to position a large number of bags on the bag dispenser, - the operation of bagging the bread is made easier and secure because of the solidity and a certain rigidity obtained by the meeting between them of the upper parts of the bags, - each bag is easily detached from the next, - the use of this set allows an indisputable time saving, ensures a greater hygiene due to the reduction both in the number of manipulations required and the risk

L'invention est representee a titre d'exemple non limitatif, sur The invention is represented by way of nonlimiting example, on
les figures l et 2.Figures 1 and 2.
La figure l represente un ensemble de sacs comportant une Figure l shows a set of bags comprising a

Selon un mode de realisation de ['invention et selon les figures l et 2, ['ensemble objet des presentes est constitue de sacs (l), de forme allongee, confectionnes en papier et en polypropylene ou en materiaux According to an embodiment of the invention and according to FIGS. 1 and 2, the assembly which is the subject of these presents consists of bags (l), of elongated shape, made of paper and of polypropylene or of materials.

similaires; chaque sac (1) comporte, sur toute sa longueur dans l'exemple decrit, au moins une fenetre en polypropylene (2) et, au niveau de son ouverture, une decoupe (3) etudiee de facon a permettre, d'une part, la reunion entre elles sans aucun obstacle, de toutes les parties superieures (4) des parties en polypropylene (2) et, d'autre part, de facon like; each bag (1) comprises, over its entire length in the example described, at least one polypropylene window (2) and, at its opening, a cutout (3) studied so as to allow, on the one hand, the meeting between them without any obstacle, of all the upper parts (4) of the polypropylene parts (2) and, on the other hand, so

(:es parties superieures (4) forment ainsi un ensemble (5) perce de part en part (6) en son centre; elles vent solidaires les unes des autres sur le pourtour de la cavite (6) obtenue par ['application d'une pointe chaude au travers de ['ensemble (5); une pre-decoupe (7) realisee sur le pourtour de la cavite (6) lors de ['application de la pointe chaude, facilite (: the upper parts (4) thus form an assembly (5) pierced right through (6) in its center; they are integral with each other around the periphery of the cavity (6) obtained by the application of a hot tip through the assembly (5); a pre-cut (7) made on the periphery of the cavity (6) during the application of the hot tip, facilitates
l'arrachage de chaque sac (1) de ['ensemble. the uprooting of each bag (1) from the assembly.
Les qualites propres au polypropylene en reaction a la chaleur, permettent d'obtenir, par ce procede, une decoupe nette formant la cavite (6); de meme, la pre-decoupe (7) est aisement realisee a ['aide d'un The qualities specific to polypropylene in reaction to heat, make it possible to obtain, by this process, a clear cut forming the cavity (6); similarly, the precut (7) is easily carried out using a
outillage particulier, lors de cette operation. special tools during this operation.
Le diametre de la cavite en principe circulaire (6) doit etre suffisant pour permettre d'enfiler ['ensemble de sacs ainsi obtenu sur l'axe des dispositifs utilises pour distribuer les sacs a pains; une fois ['ensemble en place, il suffit alors de firer sur chaque sac (1) pour le The diameter of the generally circular cavity (6) must be sufficient to allow threading of the set of bags thus obtained on the axis of the devices used to distribute the bread bags; once ['together in place, then just pull on each bag (1) to the
detacher du suivant selon la pre-decoupe (7). detach from the next according to the precut (7).
Lorsque la largeur des sacs (1) le justifie, deux ou plusieurs cavites (6) peuvent etre amenagees, dans les parties en polypropylene (4), de fa,con a permettre un bon maintien de ['ensemble sur les axes des When the width of the bags (1) justifies it, two or more cavities (6) can be arranged in the polypropylene parts (4) so as to allow good maintenance of the assembly on the axes of the
