CA 2348977

A fill-through-the-top reclosable package includes first and second opposing body panels joined to each other along a pair of sides and a bottom bridging the pair of sides. The package is provided with a reclosable fastener extending along a package top disposed opposite the bottom. The fastener includes first and second opposing tracks. The first track includes a male profile, while the second track includes a female profile adapted to releasably interlock with the male profile. To provide tamper evidence, the first and second tracks may be joined to each other along an area of weakness. When making the package, the first track is first attached to the first panel, the package is filled with a product via a fill opening between the second track and the second panel, and then the second track is attached to the second panel.

L'invention porte sur un sac (10) refermable à remplissage par le haut. Ce sac est constitué de premier et second panneaux (12, 14) opposés, assemblés le long d'une paire de côtés (16), et d'un fond (20) réunissant les deux côtés latéraux. Le sac est pourvu d'un élément de fixation (23) refermable qui s'étend le long de la partie supérieure du sac opposée au fond. Cet élément de fixation comprend des première et seconde glissières (24, 26) opposées, la première glissière (24) présentant un profil mâle (28) et la seconde (26) un profil femelle (32) adapté pour s'enclencher de manière libérable avec le profil mâle. Afin d'assurer l'inviolabilité du sac, les première et seconde glissières peuvent être assemblées le long d'une zone de faiblesse (40). Lors de la fabrication du sac, la première glissière est d'abord fixée au premier panneau (12), le sac étant rempli d'un produit par une ouverture située entre la seconde glissière et le second panneau (14), et la seconde glissière est ensuite fixée au second panneau.
