Abstract

A quick connect coupling having a socket portion adapted to be attached to a disposable beverage container with the parts of the socket being fabricated from two different plastics, one being flexible and the other rigid. The socket includes valving and a novel socket end connector sleeve which cooperates with a male plug that has both a plug valve and a check valve therein. The connector sleeve is retained on the socket body by cooperating interengaging ridges on both the sleeve and the body whereby the sleeve may be nonrotatably assembled. The connector sleeve further includes an integral portion which functions as a socket valve seat.

Claims

1. A socket connector for use in a quick connect coupling comprising:

a socket connector body having a tubular extension projecting therefrom, a bore in said body opening outwardly through said tubular extension, valve means in said bore for movement longitudinally of said bore, and a socket end carried by said socket body, said socket end comprising a connector sleeve telescopically assembled to said tubular extension, said connector sleeve including socket connector means formed at one end thereof with said socket connector means being adapted for mating cooperation with a complementary portion of the quick connect coupling, said connector sleeve further including radially inwardly extending means integral therewith extending into said bore and defining a valve seat cooperating with said valve means to control the flow of fluid through said connector; and

an axially opening circumferentially continuous recess having a closed interior end formed in said sleeve with the terminal end of said tubular extension being sealingly received in said closed end recess when said sleeve is assembled to said connector body.

2. The sockEt connector of claim 1 wherein said tubular extension and said connector sleeve have complementary engaging means for nonrotatably assembling said sleeve to said tubular extension.

3. A socket connector for use in a quick connect coupling comprising;

a socket connector body and including a generally tubular portion, a bore in said body opening outwardly through said tubular portion, valve means in said bore for controlling the flow of fluid therethrough, a socket end carried by said socket body, said socket end comprising a connector sleeve having a socket opening formed in one end thereof and adapted to receive a male plug of a quick connect coupling, and complementary engaging means comprising circumferential ridges on said tubular portion and said sleeve for non-rotatable telescopic assembly of said sleeve to said tubular portion;

said circumferential ridges on said sleeve being cammed over said ridges on said tubular portion as said sleeve is being assembled and interfitting with said ridges on said tubular portion in the assembled position to retain said sleeve in a fixed telescopic assembled position when said socket connector is used in a quick connect coupling.

4. A disposable valve for use with a disposable fluid carrying container comprising, a valve body including a tubular portion, a bore in said body opening outwardly through said portion, valve means movable longitudinally in said bore, sleeve means telescopically assembled to said tubular portion and including a first portion sealingly engaged with said tubular portion and a second portion cooperating with said valve means to control the flow of fluid through said bore, said sleeve means being formed from a plastic material having a relatively low modulus of elasticity and said tubular portion and said valve means being formed from a plastic material having a substantially higher modulus of elasticity.

5. The valve of claim 4 and further including complementary engaging means on said tubular portion and said sleeve means for nonrotatable assembly and retention of said sleeve means to said tubular portion.

6. A male plug for a quick connect coupling including a tubular stem and bore opening through one end thereof, a valve seat in said bore and valve means cooperating with said valve seat to close said bore and biasing means acting on said means to bias said valve means into engagement with said valve seat, the improvement comprising:

a valve body extending into the other end of said tubular stem, said valve body including a flow passage therethrough opening into the bore in said tubular stem, a valve member slidably received in said through passage, a valve seat, biasing means acting on said valve member to bias said valve member into engagement with said valve seat whereby fluid may flow through said plug in only one direction.

7. The male plug of claim 6 wherein said valve seat is carried in the bore of said tubular stem.

8. The male plug of claim 7 wherein said valve seat comprises an annular plate, a radial shoulder in the bore in said stem, said valve plate being clamped between said radial shoulder and the end of said valve body extending into said stem.

9. The male plug of claim 8 wherein said biasing means for said valve means comprises spring means abutting said valve plate.

10. A socket connector for use in a quick connect coupling comprising, a socket connector body having a tubular extension projecting therefrom, a bore in said body opening outwardly through said tubular extension, valve means in said bore, and a socket end carried by said socket body, said socket end comprising a connector sleeve telescopically assembled to said tubular extension, said connector sleeve including radially inwardly extending means integral therewith extending into said bore and defining a valve seat cooperating with said valve means to control the flow of fluid througH said connector, said connector sleeve being formed from a plastic material having a relatively low modulus of elasticity and said valve means being formed from a plastic material having a substantially higher modulus of elasticity.
