Title
(EN) ANTI-BLOCKING ADHESIVE VALVE, SHEET INCLUDING THIS ADHESIVE VALVE, PACKAGING MADE FROM THIS SHEET AND PROCESS FOR PRODUCING THEM
(FR) SOUPAPE ANTI-BLOCAGE ADHÉSIVE, FEUILLE COMPRENANT CETTE SOUPAPE ADHÉSIVE, EMBALLAGE RÉALISÉ À PARTIR DE CETTE FEUILLE ET LEUR PROCÉDÉ DE PRODUCTION
Abstract
(EN) The invention relates to a food container, a semi-finished product from which this container is made, an adhesive valve incorporated in said semi-finished product, and the method for manufacturing them, wherein the adhesive valve (100) comprises: an adhesive label (101 ) which has an upper surface (101a) and a lower surface (101 b), where at least one first incision (102) connects the two upper and lower surfaces so as to form a passage for a fluid. a covering membrane (103) applied to the upper surface (101a) of the adhesive label (101 ). The adhesive valve (100) has, between the adhesive label (101 ) and the covering membrane (103); a first zone (A), in which the adhesive label (101 ) and the covering membrane (103) are not joined together by means of adhesive and which, viewing the adhesive valve (100) in plan view, overlaps the first incision (102); a second zone (B), in which the adhesive label (101 ) and the covering membrane (103) are not joined together by means of adhesive, and which is adjacent to the first zone (A) or integral therewith so as to define with the latter a discharge channel for a fluid, which extends from the at least one first incision (102) towards a perimeter edge of the covering membrane (103); a third zone (C), in which a second adhesive (105) fixes the covering membrane (103) to the adhesive label (101 ).
(FR) L'invention concerne un récipient à usage alimentaire, un produit semi-fini à partir duquel est réalisé ce récipient, une soupape adhésive incorporée dans ledit produit semi-fini, et leur procédé de fabrication, la soupape adhésive (100) comprend : une étiquette adhésive (101) qui présente une surface supérieure (101a) et une surface inférieure (101b), où au moins une première incision (102) relie les deux surfaces supérieure et inférieure de manière à former une voie de passage destiné à un fluide. Une membrane de recouvrement (103) est appliquée sur la surface supérieure (101a) de l'étiquette adhésive (101). La soupape adhésive (100) présente, entre l'étiquette adhésive (101) et la membrane de recouvrement (103) ; une première zone (A), dans laquelle l'étiquette adhésive (101) et la membrane de recouvrement (103) ne sont pas reliées l'une à l'autre au moyen d'un adhésif et qui, lorsque la soupape adhésive (100) est observée en vue en plan, chevauche la première incision (102) ; une deuxième zone (B), dans laquelle l'étiquette adhésive (101) et la membrane de recouvrement (103) ne sont pas reliées l'une à l'autre au moyen d'un adhésif, et qui est adjacente à la première zone (A) ou solidaire de cette dernière de manière à définir ensemble un canal d'évacuation destiné à un fluide, qui s'étend de ladite première incision (102) à un bord périphérique de la membrane de recouvrement (103) ; une troisième zone (C), dans laquelle un second adhésif (105) fixe la membrane de recouvrement (103) sur l'étiquette adhésive (101).
