Abstract

A one-piece sealed disposable enema unit with a lubricated rectal tip is disclosed. The rectal tip of the unit is sealed with a break-off tab. Attached to the tab is a sleeve which covers the exterior of the rectal tip and prevents contamination of the lubricant. Before use, the break-off tab must be twisted off and the tab with the attached sleeve removed. Therefore, the unit is tamper proof and security of the contents is insured.

Claims

1. A container having a tamper-resistant closure comprising:

a molded closed container including an integrally formed section from which at least one break-off tab projects, said tab having means forming an external opening in said container when said tab is moved relative to other portions of said container, and a projective sleeve positioned over and providing a protective environment for said section, said sleeve including means for securing said sleeve to said section and for engaging said tab, whereby on relative movement of said sleeve and tab said sleeve may be removed from engagement with said section and said tab is severed to form said external opening.

2. The container of claim 1, wherein said section is coated with a lubricant.

3. The container of claim 1, wherein said section is elongated and tapered.

4. The container of claim 3, wherein said tab is disposed at the tip of said section.

5. The container of claim 1, wherein said sleeve is comprised of a heat shrinkable material.

6. The container of claim 5, wherein said sleeve is heat shrunk to said tab.

7. The container of claim 1, wherein said sleeve forms an interference fit with said tab.

8. The container of claim 1, wherein said sleeve and tab are adapted to remain engaged when said tab is severed to permit simultaneous removal of said sleeve and tab from said container.
