Flexible, re-sealable containers and systems for retaining solids, liquids, gasses or combinations thereof. Containers and related system embodiments include, in combination or in the alternative, polyethylene and polyurethane laminated panels; linear interlocking closure elements having a pair of opposed sealing members; a removable slider that include structure for accommodating varying thickness sealable closures, for progressively engaging opposing interlock portions of the sealing members of the closure, for engaging portions of a container adjacent to the closure to resist unintended separation thereof and/or engaging portions of the sealing members to provide a means for resisting tensioned separation of the slider from the container, for incorporating permanent or removable handle(s) to facilitate transportation, mounting, attaching or adapting of the container, and/or for selectively modifying the sealing pressure applied to the sealable closures during closure operations; and/or novel high strength apertures/handles that are integral with a flexible container.

L'invention concerne des récipients et des systèmes re-scellables flexibles, destinés à contenir des solides, des liquides, des gaz et des combinaisons de ceux-ci. Des modes de réalisation de ces récipients et systèmes comprennent, en combinaison ou en variante : des panneaux stratifiés de polyéthylène et de polyuréthane ; des éléments de fermeture à enclenchement linéaires pourvus d'une paire d'éléments de scellage opposés ; un coulisseau amovible comprenant une structure destinée à accueillir des fermetures scellables d'épaisseurs diverses, pour la mise en contact progressive de parties d'enclenchement opposées des éléments de scellage de la fermeture, de sorte à mettre en contact des parties d'un récipient adjacentes à la fermeture pour résister à une séparation non intentionnelle et/ou à mettre en contact des parties des éléments de scellage pour fournir un moyen de résistance à la séparation par tension du coulisseau du récipient, pour incorporer une/des poignée(s) permanente(s) ou amovible(s) de sorte à faciliter le transport, le montage, la fixation ou l'adaptation du récipient et/ou modifier de façon sélective la pression de scellage appliquée sur les fermetures scellables lors d'opérations de fermeture ; et/ou de nouvelles ouvertures/poignées haute résistance formées solidaires d'un récipient flexible.
