CA 2721473

A bag structure includes a bag body including side walls having inner and outer surfaces, and the bag body further includes a top end and a bottom end. A closure member is coupled to the top end for opening and closing the bag body, and an inner seal is formed proximate to the top end, without the use of heat driven from the outside surface of the bag wall to the inside surface of the bag wall. Further, the top end of the bag is folded over, and an adhesive member is secured to the bag body. The adhesive member includes a reinforced section and an adhesive section. The adhesive member is configured to retain the top end of the bag body in a folded over relationship until the adhesive member is severed along the reinforced section.

L'invention concerne une structure de sac qui comprend un corps comportant des parois latérales à surfaces internes et externes, et le corps comprend, en outre, une extrémité supérieure et une extrémité inférieure. Un organe de fermeture est couplé à l'extrémité supérieure en vue d'ouvrir et de fermer le sac, et un scellement interne formé à proximité de l'extrémité supérieure, sans utiliser la chaleur entraînée de la surface externe de la paroi du sac vers la surface interne de celle-ci. En outre, l'extrémité supérieure du sac est repliée, et un élément adhésif est fixé sur le corps du sac. Cet élément adhésif est conçu de manière à maintenir l'extrémité supérieure du corps du sac en position repliée jusqu'à ce que l'élément adhésif soit coupé le long de la section renforcée.
