Abstract

La présente invention se rapporte à un récipient sans valve pour fluide ou pour gaz et qui se ferme hermétiquement de lui-même, pouvant être utilisé dans une grande diversité d'applications, notamment des matériaux de calage, de remplissage, des matelas, des radeaux et autres. Le récipient est formé d'un ou plusieurs éléments gonflables (101) se fermant hermétiquement d'eux-mêmes, chaque élément gonflable étant formé d'une paire de cellules gonflables (103, 105). Chaque cellule est composée d'une feuille intérieure (17) et d'une feuille extérieure (109) de matériau thermoplastique ou imperméable, les feuilles étant scellées ensemble à leurs bordures (111), définissant ainsi la cellule gonflable. Les feuilles intérieures (107) de chaque cellule dans la paire sont scellées ensemble de telle sorte que les bordures du joint hermétique définissent un conduit (115) de remplissage à travers lequel le fluide ou le gaz peut passer entre les cellules. Des passages (119) dans les feuilles intérieures des deux cellules à l'intérieur du conduit de remplissage permettent au fluide ou au gaz de passer du conduit de remplissage vers les deux cellules afin de provoquer le gonflage. Lorsque les cellules ont été entièrement gonflées, la pression interne du gaz et les forces d'étirement latéral conduisent les feuilles internes de cellules de venir en contact, ce qui provoque la fermeture du conduit de remplissage, et isolant ainsi les passages de l'environement extérieur et provoquant la fermeture hermétique automatique du récipient. En outre, le récipient peut être créé en utilisant des agencements de tels éléments de fermeture hermétique automatique pouvant être gonflés individuellement ou à partir d'une source unique alimentant un distributeur commun.
