This invention is related to a self-sealing valve for inflatable articles, including balloons, made of non-elastomeric material of the kind of valves formed by multiple layers of thermo-plastic film joined by heat which form three sections; a nozzle, main channel and a multi-valued section. This valve design permits the production of balloons or inflatable objects with a valve without requiring sophisticated machinery for the exact placement of the valve in the article or balloon. This is characterized in that the nozzle of the article consists of four films; two external films with an outer face that is compatible with heat fusion with the material of the inflated article in which the valve is to be placed and inner faces that are compatible with each other and the inner films with outer faces that are compatible with the outer films and inner faces that are incompatible with each other and outer films.
L'invention concerne une valve à auto-obturation pour le gonflage d'articles gonflables, en particulier des ballons, en matériau non élastomère, cette valve étant du type formé par laminage multicouche de pellicules thermoplastiques jointes par apport de chaleur et comprenant trois sections: une embouchure, un canal principal et une section multivalve. Cette conception de valve permet de produire des ballons ou articles gonflables avec valve incorporée sans avoir recours à des machines très sophistiquées pour le montage précis de la valve dans l'article ou ballon gonflable. La valve se caractérise en ce que l'embouchure de l'article comprend trois pellicules, deux extérieures avec leur face externe compatible à la fusion thermique avec le matériau de l'article gonflable où l'on souhaite monter la valve et leurs faces internes compatibles entre elles, et les pellicules intérieures avec leurs faces externes compatibles avec les pellicules externes et leurs faces internes incompatibles entre elles et avec les pellicules externes.
