Abstract

A package for a medical device such as an intermittent catheter has a case which is closed at one end and open at the other end. A cap is connected to the case by a hinge to permit selectable movement of the cap between an open position, wherein access is provided to the open end of the case, and a closed position, wherein the cap prevents access to the open end of the case. A seal is connected to one of the cap and case. The seal is engageable with the other of the cap and case when the cap is closed to form a barrier that maintains a sterile environment inside the package. The seal can be repeatedly made and broken whenever the user closes or opens the cap, respectively. The case includes a pair of slots at the open end. A pair of latches are formed in the cap. The latches fit into the slots to prevent lateral forces from distorting the cap when the cap is closed.

First claim

The invention claimed is:

1. An assembly of a catheter and a package therefor, comprising:
a case comprising a tube defined by a hollow tubular wall, said case having a longitudinal axis and is closed at one end and open at an opposite end of the tube wherein said open end terminates at a rim comprising a front portion and a rear portion;
a cap having a hollow shell with a front portion and a rear portion;
a hinge having a first end connected to the cap and a second end connected to the case, the hinge permitting selectable movement of the cap between an open position, wherein access is provided to the open end of the case, and a closed position;
a catheter having a tube and funnel attached to the tube, the funnel being removably engageable with an interior surface of the case, with a portion of the funnel when so engaged extending axially beyond the rim and the shell of the cap surrounding said extending portion of the funnel when the cap is in the closed position and wherein a portion of the catheter funnel extends axially beyond the rim and is exposed when the cap is in the open position; and
wherein said tubular wall flares outwardly and defines a neck portion in said tube between said open and closed ends, said neck portion having an increased diameter relative to the remainder of the tube.

2. The assembly of claim 1 , wherein the case further comprises a collar that extends from a top of the neck portion to the open end of the tube.

3. The assembly of claim 2 , wherein the collar of the case has an enlarged diameter.

4. The assembly of claim 3 , wherein a vertical axis of the collar is offset from a vertical axis of the remainder of the tube.

5. The assembly of claim 1 , wherein the shell of the cap is generally cup-shaped.

6. The assembly of claim 1 , wherein the cap includes a top wall and a side wall and the top wall and side wall merge at the front portion of the cap to form a lip.

7. The assembly of claim 1 , wherein the hinge is connected to the rear portions of the case and cap.

8. The assembly of claim 1 , wherein the cap includes a pair of latches that extend away from a top wall of the cap.

9. The assembly of claim 1 , wherein the hollow tube of the case defines a case cavity and the shell of the cap defines a cap cavity and, wherein the cap is in the closed position the longitudinal axis of the tube intersects the cap cavity such that the cap cavity provides an extension of the case cavity.

10. The assembly of claim 1 , wherein the package includes a stem section and a flip cap section, the stem section including the case and the flip cap section including the cap.

11. The assembly of claim 10 , wherein the stem section and the flip cap section are fixed to one another.

12. The assembly of claim 10 , wherein an upper portion of the stem section extends through and fits tightly within an opening in the flip cap section.

13. The assembly of claim 10 , wherein an upper portion of the stem section has a circular cross section that fits snugly inside an opening of the flip cap section.

14. The assembly of claim 13 , wherein the circular cross section of an upper portion of the stem section ceases at the top end of the stem section at a bowed out portion.

15. The assembly of claim 10 , wherein the tubular wall defines a first vertical axis and further comprising a cylindrical, axial projection on the flip cap section, the projection defining a second vertical axis that is offset from the first vertical axis.

16. The assembly of claim 10 , wherein the flip cap section has a body portion surrounding the exterior of an upper portion of the stem section and engaged with the stem section.
