Abstract

Abstract A sterilized hypodermic needle is within a container having a necked receiver section and a cap section rotatably receiving the neck and providing a hermetic seal when the container is closed with the proximate ends of its sections abutting or nearly abutting and the sections have flat surfaces that are then substantially coplanar. A seal extends across the junction between the sections and is heat-sealed to flat surfaces and is of a material that will stretch, become deformed and ruptures as the container is opened. The seal is formed by first arranging a series of containers in a side-by-side, abutting relationship. A strip of the seal-forming material is disposed across the series to overlie the junction between the sections of the several containers and is secured to the exposed flat surfaces by heat seals extending lengthwise of the strip on opposite sides of the junctions and, finally, the tape is severed transversely to free each container.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 184 words
A sealed container with a sterilized hypodermic needle within it, said container comprising a receiver section provided with a cylindrical neck at one end and having a chamber opening through the neck and a cap section having a chamber receiving the neck within it, the mouth of the cap portion and the neck being of a fit permitting the sections to be turned relative to each other but dimensioned to establish a friction fit such as to provide a hermetic seal, said container portions including external, flat-surfaced portions that are substantially co-planar, and a seal in the form of a strip overlying said flat-surfaced portions and extending across the junction between the container sections, the container and the sealing strip being of heat sealable material, and heat seals, one between each flat-surfaced portions and said strip, said sealing strip also being of a material that will stretch somewhat and be deformed before rupturing, the seal stretching and rupturing as one container section is turned relative to the other as the sections are pulled apart with the proximate ends of the ruptured seal permanently deformed.
Claim 2
Dependent Claim 184 words
A sealed container with a sterilized hypodermic needle within it, said container comprising a receiver section provided with a cylindrical neck at one end and having a chamber opening through the neck and a cap section having a chamber receiving the neck within it, the mouth of the cap portion and the neck being of a fit permitting the sections to be turned relative to each other but dimensioned to establish a friction fit such as to provide a hermetic seal, said container portions including external, flat-surfaced portions that are substantially co-planar, and a seal in the form of a strip overlying said flat-surfaced portions and extending across the junction between the container sections, the container and the sealing strip being of heat sealable material, and heat seals, one between each flat-surfaced portions and said strip, said sealing strip also being of a material that will stretch somewhat and be deformed before rupturing, the seal stretching and rupturing as one container section is turned relative to the other as the sections are pulled apart with the proximate ends of the ruptured seal permanently deformed.
Claim 3
Dependent Claim 55 words
The package of claim 1 in which the heat seals are so spaced from the junction between the container sections that any unsealed seal section overlies the proximate ends of the container sections whereby the ruptured stretched ends of the seal are free as signals that the sterility of the needle may have been lost.
Claim 4
Dependent Claim 20 words
The package of claim 1 in which the seal is of a color contrasting with that of the container sections.
Claim 5
Dependent Claim 15 words
The package of claim 1 in which the container sections are square in cross section.
Claim 6
Dependent Claim 11 words
The package of claim 1 in which the seal is polyethylene.
