Title
(EN) RECLOSABLE LAP SEAL PACKAGES
(FR) EMBALLAGES REFERMABLES À SCELLEMENT PAR RECOUVREMENT
Abstract
(EN)
The present disclosure is directed to a reclosable package comprises a front wall, a rear wall, and an upper closure. At the upper closure, at least a portion of a surface of the rear wall is sealed to an exterior surface of the front wall at a first adhesion strength. According to embodiments, the application of a force greater than the first adhesion strength to the rear wall in a direction away from the front wall is operable to separate the portion of a surface of the rear wall from the exterior surface of the front wall. After, the return of the portion of the surface of the rear wall and an application of a force on the rear wall in the direction of the front wall is operable to reseal the portion of the interior surface of the rear wall to the exterior surface of the front wall.
(FR)
La présente invention concerne un emballage refermable comprenant une paroi avant, une paroi arrière et une fermeture supérieure. Au niveau de la fermeture supérieure, au moins une partie d'une surface de la paroi arrière est scellée à une surface extérieure de la paroi avant avec une première force d'adhérence. Selon des modes de réalisation, l'application d'une force supérieure à la première force d'adhérence à la paroi arrière dans une direction s'éloignant de la paroi avant permet de séparer la partie d'une surface de la paroi arrière par rapport à la surface extérieure de la paroi avant. Ensuite, le retour de la partie de la surface de la paroi arrière et l'application d'une force sur la paroi arrière dans la direction de la paroi avant permettent de resceller la partie de la surface intérieure de la paroi arrière sur la surface extérieure de la paroi avant.
