Abstract

A connector including a base and first and second tubular members projecting in generally opposite directions from the base. Each of the tubular members has a longitudinal passage therein, and the passages are communicable with each other. The base can be coupled to first and second containers to place the first and second tubular members within the first and second containers, respectively, so that communication between the containers can be established. The connector includes a plurality of pointed projections extending away from the base to accommodate certain production tolerances in the containers.

Claims

1. An apparatus attachable to a container with an opening which container has penetrable stopper means and an apertured cap for securing said stopper means within said opening, said cap having a relatively deformable outer end surface and a shoulder inwardly of the end surface and with the distance between the shoulder and the end surface being subject to variations, said apparatus comprising:

a base;

a resilient coupling member projecting from the base and adapted to receive the region of the container adjacent the shoulder;

said coupling member having a first jaw extending radially inwardly in spaced relationship to the base for engaging the shoulder and retaining the container against movement away from the apparatus;

a second jaw on said base radially inwardly of the coupling member; and

said second jaw terminating proximally of the first jaw in at least one relatively sharp point which is positioned to contact said outer end surface of said cap when said apparatus is attached to said container whereby the region of the container between the shoulder and the end surface of said cap can be gripped between the jaws to retain the connector on the container with the relatively sharp point deforming the deformable surface of the container sufficiently to accommodate variations in the distance between the shoulder and the end surface of the cap.

2. An apparatus as defined in claim 1 wherein said second jaw terminates proximally of the first jaw in at least three of said relatively sharp points.

3. An apparatus as defined in claim 1 wherein said second jaw terminates proximally of the first jaw in a plurality of substantially equally spaced relatively sharp points.

4. An apparatus as defined in claim 1 wherein said second jaw includes a raised section terminating distally in said relatively sharp point.

5. An apparatus as defined in claim 1 wherein said coupling member includes an outer segmented skirt and said second jaw includes an inner skirt terminating distally in a plurality of said relatively sharp points.

6. An apparatus as defined in claim 1 including a tubular member projecting from said base in the same general direction as the coupling member, said tubular member lying radially inwardly of the coupling member and being adapted to project into the container when the apparatus is attached to the container.

7. An apparatus as defined in claim 1 including a tubular member projecting from the base in a direction generally opposite to the direction in which the coupling member projects from the base and a second coupling member for use in coupling the base to a second container with the tubular member projecting into the second container.
