Title
(EN) SEALING APPARATUS
(FR) APPAREIL D'ETANCHEIFICATION
Abstract
(EN)
Apparatus that can form a seal in a hollow article, comprises: (a) an inflatable sealing member which can be spirally coiled and inflated in the hollow article to seal the article; and (b) a retaining member; wherein the retaining member has an opening preferably a slot, through which the sealing member can extend and/or the sealing member has an opening through which the retaining member can extend, when the sealing member is so coiled and inflated in the article in use, thereby impeding helical uncoiling of the inflated sealing member.
(FR)
Un appareil servant à former un joint d'étanchéité dans un article creux comprend: (a) un élément d'étanchéification gonflable qui peut être enroulé en spirale et gonflé dans l'article creux pour l'étanchéifier; et (b) un élément de retenue qui comporte une ouverture, de préférence une fente, par laquelle l'élément d'étanchéification peut s'étendre, et/ou l'élément d'étanchéification comporte une ouverture par laquelle l'élément de retenue peut s'étendre lorsque l'élément d'étanchéification est enroulé en spirale et gonflé dans l'article en cours d'utilisation, ce qui empêche le déroulement hélicoïdal de l'élément d'étanchéification gonflé.
