Abstract:
A leaktight container comprising a container fitted with a valve which lies inside the container formed between two flexible sheets extending from one edge of the container to another edge of the container wherein said one edge and said another edge are joined to the two flexible sheets which are further connected together along two non-converging connection lines whereby when the two flexible sheets are parted, a passage is delimited between the two flexible sheets, wherein the two nonconverging connection lines extend from said one edge of the container to said another edge of the container, wherein a portion of one of the two flexible sheets, which lies between the two non-converging connection lines is fixed to a tab cut in an adjacent wall of the container and attached to said adjacent wall by one tab end, and another tab end comprising a free tab end so as to form means for grasping; a leaktight connection between one of the two flexible sheets and the adjacent wall of the container extending around a periphery of the tab, said tab being adapted to break a portion of said one sheet which is fixed to said tab by pulling on said free tab end, in order to place the passage in communication from inside to outside the container, a cut being made through at least one of the two flexible sheets between the non-converging connection lines, said cut being distant from said portion of the at least one of the two flexible sheets which is fixed to the tab and serving to place said passage in communication with the inside of the container.
