Definitions

  • Containers such as sacks, pouches, or bags, are generally used to hold or store objects. Containers may be used, for example, to package merchandise for delivery to clients or customers. Some containers include a closing or sealing mechanism that allows the container to be sealed or closed. Some known containers are closed, for example, using twist ties, draw strings, zipper-like self-closing features, adhesive strips, and/or heat seals. At least some known containers, however, are prone to leaking. It can be onerous and/or costly to seal at least some known containers in a leak-proof manner.

Abstract

L'invention concerne un récipient scellable, comprenant une première couche et une seconde couche accouplée à la première couche de façon à délimiter une cavité entre ces dernières. La seconde couche est accouplée à la première couche au niveau d'un premier secteur latéral, d'un secteur inférieur et d'un second secteur latéral opposé au premier secteur latéral, de telle sorte qu'une ouverture en communication fluidique avec la cavité est délimitée entre la première couche et la seconde couche au niveau d'un secteur supérieur opposé au secteur inférieur. La seconde couche comprend une partie rabat au niveau du secteur supérieur s'étendant au-delà d'un bord supérieur de la première couche. Un premier mécanisme d'accouplement est accouplé à une surface interne de la seconde couche faisant généralement face à la première couche au niveau du secteur supérieur, et un second mécanisme d'accouplement est accouplé à une surface externe de la seconde couche faisant généralement face à la première couche au niveau du secteur supérieur.
