Title (EN) FLEXIBLE PACKAGES WITH CLOG RESISTANT DEGASSING VALVE AND METHODS OF MAKING THE SAME
(FR) EMBALLAGES SOUPLES DOTÉS D'UNE VALVE DE DÉGAZAGE RÉSISTANT À L'OBSTRUCTION ET PROCÉDÉS DE FABRICATION DESDITS EMBALLAGES SOUPLES
Abstract: front page image
(EN)A flexible package with a one-way, pressure-equalizing or degassing valve and method of making the same is provided. The package includes a tortuous path preventing particulate materials, e.g., fine powders, from clogging or interfering with opening and closing of said valve. The package includes a heat seal including discontinuities or gaps which defines a tortuous path between the valve and the compartment within the package in which the particulate material is located, allowing air and internal gases trapped in the package to escape through the valve while preventing fine powders, dust and particulate from reaching the valve body by trapping or collecting them in the tortuous path.
(FR)L'invention concerne un emballage souple doté d'une valve unidirectionnelle d'égalisation de pression ou de dégazage, et un procédé de fabrication dudit emballage souple. L'emballage comprend un trajet tortueux empêchant des matériaux particulaires, par exemple des poudres fines, de boucher ou d'entraver l'ouverture et la fermeture de ladite valve. L'emballage comprend un joint thermique comprenant des discontinuités ou des espaces qui délimitent un trajet tortueux entre la valve et le compartiment à l'intérieur de l'emballage dans lequel se trouve le matériau particulaire, ce qui permet à l'air et aux gaz internes piégés dans l'emballage de s'échapper à travers la valve, tout en empêchant les poudres fines, la poussière et les particules d'atteindre le corps de valve par piégeage ou collecte de ces dernières dans le trajet tortueux.
