Abstract
Abstract The invention is a coupler for interconnecting the ends of two fluid conduits wherein the connectors are each mounted inwardly of the open end of respective cupped members; the cupped members telescope one over the other and one of them has a flared end to assist in the initial alignment of the telescoping action. The connectors connect with each other to establish fluid flow as the cupped members are telescoped together.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
382 words
A coupler comprising a first part, said first part having a first cupped member integral therewith, said first cupped member having a bottom and an open end, said first cupped member having an exterior cylindrical wall extending rearwardly of the open end to said bottom and formed integral therewith and a flow opening extending through the bottom of said first cupped member; a second part, said second part having a second cupped member integral therewith, said second cupped member having a bottom and an open end, said second cupped member having an interior cylindrical wall extending from the open end to said bottom and formed integrally therewith and a flow opening extending through the bottom of said second cupped member; the said interior cylindrical wall of the second cupped member and said exterior cylindrical wall of the first cupped member having diameters for sliding relation with respect to each other whereby the two cupped members can be telescoped with respect to each other along an axis common to the cylindrical axis of their said respective cylindrical walls when the cylindrical axes of their respective cylindrical walls are aligned and their open ends are opposed whereby said first part and a second part are telescopical with respect to each other; a connector for each of said cupped members for joining fluid flow between the flow openings of said cupped members, said connector in each of said cupped members being spaced inwardly from the open end of its respective cupped member, said connectors being aligned in their respective cupped members and adapted to connect together in fluid flow relation within the first cupped member as the cupped members are telescoped together; an end portion of the inside cylindrical wall of said second cupped member being flared outwardly adjacent its open end to a diameter greater than the outside diameter of said first cupped member whereby to cooperate therewith and guide said cupped members into axial alignment when they are telescoped together; the said cupped members when fully telescoped together to dispose the interior cylindrical wall of the second cupped member and the exterior cylindrical wall of the first cupped member in fully telescoped relation being adapted to cooperate and support said connectors connected in fluid flow relation and means for holding said connectors connected.
Claim 2
Dependent Claim
382 words
A coupler comprising a first part, said first part having a first cupped member integral therewith, said first cupped member having a bottom and an open end, said first cupped member having an exterior cylindrical wall extending rearwardly of the open end to said bottom and formed integral therewith and a flow opening extending through the bottom of said first cupped member; a second part, said second part having a second cupped member integral therewith, said second cupped member having a bottom and an open end, said second cupped member having an interior cylindrical wall extending from the open end to said bottom and formed integrally therewith and a flow opening extending through the bottom of said second cupped member; the said interior cylindrical wall of the second cupped member and said exterior cylindrical wall of the first cupped member having diameters for sliding relation with respect to each other whereby the two cupped members can be telescoped with respect to each other along an axis common to the cylindrical axis of their said respective cylindrical walls when the cylindrical axes of their respective cylindrical walls are aligned and their open ends are opposed whereby said first part and a second part are telescopical with respect to each other; a connector for each of said cupped members for joining fluid flow between the flow openings of said cupped members, said connector in each of said cupped members being spaced inwardly from the open end of its respective cupped member, said connectors being aligned in their respective cupped members and adapted to connect together in fluid flow relation within the first cupped member as the cupped members are telescoped together; an end portion of the inside cylindrical wall of said second cupped member being flared outwardly adjacent its open end to a diameter greater than the outside diameter of said first cupped member whereby to cooperate therewith and guide said cupped members into axial alignment when they are telescoped together; the said cupped members when fully telescoped together to dispose the interior cylindrical wall of the second cupped member and the exterior cylindrical wall of the first cupped member in fully telescoped relation being adapted to cooperate and support said connectors connected in fluid flow relation and means for holding said connectors connected.
Claim 3
Dependent Claim
70 words
A coupler as claimed in claim 1 wherein said connector of one of said cupped members comprises a membrane extending thereacross, said connector of the other cupped member comprising a tube, said membrane being breakable by the free end of said tube as said cup members are telescoped together to unite said connectors in said fluid-tight relation, said tubular connector with a membrane being connectable as to container for fluid.
Claim 4
Dependent Claim
66 words
A coupler as claimed in claim 2 wherein at least one of said cupped members has a cover for its open end for use when it is not in telescoping relation with the other cupped member, said last mentioned cupped member and its cover being formed with threads and said cover being adapted to threadedly engage therewith to form a fluid chamber that houses its connector.
Claim 5
Dependent Claim
68 words
A coupler as claimed in claim 2 wherein said cupped members have covers for their open ends for use when they are not in telescoped relation, at least one of said cupped members and at least one of said covers being threaded, the cover of at least one of said cupped members being adapted to threadedly engage therewith to form a fluid chamber within its respective cupped member.
Claim 6
Dependent Claim
14 words
A coupler as claimed in claim 2 being connected to a container for fluid.
Claim 7
Dependent Claim
66 words
A coupler as claimed in claim 5 wherein at least one of said cupped members has a cover for its open end for use when it is not in telescoping relation with the other cupped member, said last mentioned cupped member and its cover being formed with threads and said cover being adapted to threadedly engage therewith to form a fluid chamber that houses its connector.
Claim 8
Dependent Claim
68 words
A coupler as claimed in claim 5 wherein said cupped members have covers for their open ends for use when they are not in telescoped relation, at least one of said cupped members and at least one of said covers being threaded, the cover of at least one of said cupped members being adapted to threadedly engage therewith to form a fluid chamber within its respective cupped member.
Claim 9
Dependent Claim
34 words
A coupler as claimed in claim 1 wherein said means for holding said connectors connected comprises threads formed on said cupped members which are threadedly engageable with each other as they are telescoped together.
Claim 10
Dependent Claim
66 words
A coupler as claimed in claim 1 wherein at least one of said cupped members has a cover for its open end for use when it is not in telescoping relation with the other cupped member, said last mentioned cupped member and its cover being formed with threads and said cover being adapted to threadedly engage therewith to form a fluid chamber that houses its connector.
Claim 11
Dependent Claim
