Abstract

Abstract A volume variable vessel, e.g. for storing and/or collecting of fluid or dry substances and accessible through a perforatable, resilient, self-sealing membrane (16) arranged in or above the opening (12) of the vessel (11). The vessel consists of a flexible, diffusion-tight material, e.g. a plastic bag, and the portion about the opening of the vessel is attached to a connection member (14) in connection with a neck thereof and said membrane (16) is arranged at the mouth (17) of said connection member. The neck is provided with a rigid protective member (18) extending into the vessel and which is arranged to prevent that a puncturing member inserted into the vessel through the membrane will come into contact with the walls (11) of the vessel.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 149 words
A volume variable vessel, e.g. for storing and/or collecting of fluid or dry substances and accessible through a perforatable, resilient, self-sealing membrane (16) arranged in or above an opening (12) of the vessel (11), said vessel consisting of a flexible, diffusion-tight material, e.g. a plastic bag, the portion about the opening (12) of the vessel being attached to a connection member (14) in connection with a neck (13) thereof in such way that the interior of the vessel (11) communicates with said neck, at which said membrane (16) is arranged, characterized i n, that said neck (13) is provided with a rigid protective member (18) extending into the vessel and which is arranged to prevent -a puncturing member (19) inserted into the vessel through the membrane from contacting the walls (20) of the vessel (11) and which is provided with at least one side opening (21 admitting fluid communication.
Claim 2
Dependent Claim 149 words
A volume variable vessel, e.g. for storing and/or collecting of fluid or dry substances and accessible through a perforatable, resilient, self-sealing membrane (16) arranged in or above an opening (12) of the vessel (11), said vessel consisting of a flexible, diffusion-tight material, e.g. a plastic bag, the portion about the opening (12) of the vessel being attached to a connection member (14) in connection with a neck (13) thereof in such way that the interior of the vessel (11) communicates with said neck, at which said membrane (16) is arranged, characterized i n, that said neck (13) is provided with a rigid protective member (18) extending into the vessel and which is arranged to prevent -a puncturing member (19) inserted into the vessel through the membrane from contacting the walls (20) of the vessel (11) and which is provided with at least one side opening (21 admitting fluid communication.
Claim 3
Dependent Claim 31 words
A vessel as claimed in claim 1, characterized i n, that the connection member (14) is provided with a protective cover (31) of a rigid material extending over the vessel (11).
Claim 4
Dependent Claim 32 words
A vessel as claimed in claim 2, characterized in, that the protective cover (31) is slightly conical having its narrow end facing the connection member and its opposite broader end being open.
Claim 5
Dependent Claim 56 words
A vessel as claimed in claim 2 or 3, characterized i n, wherein the vessel (11) has a shape corresponding to that of the protective cover (31) and that the portion about the opening of the vessel is attached to the inside of the protective cover at the upper end thereof facing the connection member (14).
Claim 6
Dependent Claim 63 words
A vessel as claimed in claim 2 or 3, characterized i n, that said membrane (16) is designed as a piston slidingly received in said connection member (14) and arranged to be pushed upwards at an overpressure in the vessel (11), and that in said upper position of the membrane ventilation of the vessel is admitted through a passage in the connection member.
