Abstract

The present invention is connected with an ampoule package in which a stem of an ampoule is wrapped with a heat-shrinkable film, the aforesaid ampoule package being characterized in that at least a constriction of the ampoule is covered with a lower portion of the heat-shrinkable film. According to the ampoule package of the present invention, glass fine pieces of the ampoule neither go into an ampoule nor scatter around it at the time of cutting, and it is unnecessary to care about a wound and injury in cutting the ampoule.

Claims

1. An ampoule package, comprising:

an ampoule having a body, a stem attached to said body, and a constriction between said stem and said body at which said stem is separable from but integrally attached to said body;

at and adjacent said constriction, said ampoule narrows in cross-section;

a heat-shrinkable film which is shrink-wrapped around said constriction and around at least a portion of said stem and around the area of said body and of said stem that is adjacent said constriction for said film to be generally conformed to said ampoule where said film is shrink-wrapped around said ampoule.

2. The ampoule package of claim 1, wherein said ampoule and said film are of different respective materials selected such that when said stem is separated from said body by breaking the attachment therebetween at said constriction, broken and cut pieces of said ampoule might normally adhere to said film by static electricity.

3. The ampoule package of claim 1, further comprising a second heat-shrinkable film which is shrink-wrapped around said body but which does not cover said constriction, said second heat-shrinkable film being shrink-wrapped around said body before the first mentioned heat-shrinkable film is shrink-wrapped around said stem and said constriction.

4. The ampoule package of claim 1, wherein said heat-shrinkable film contacts said constriction.

5. The ampoule package of claim 1, wherein said heat-shrinkable film conforms along the entire length of said film to the exterior of said ampoule.

6. The ampoule package of claim 1, wherein said stem has an upper portion away from said constriction and said heat-shrinkable film extends up said stem to below said upper portion of said stem.

7. The ampoule package of claim 1, wherein said ampoule is comprised of glass while said film is comprised of a different heat-shrinkable material.

8. The ampoule package of claim 2, wherein said ampoule is comprised of glass while said film is comprised of a different heat-shrinkable material.
