Abstract
Abstract The present invention relates to a storage container for pre-sterilized surgical implements. The container is comprised of a bottom assembly containing at least one cavity for receiving a surgical implement such as a drill bit, pin or wire and a lid portion which is heat sealed onto the bottom assembly such that it acts as a sterile barrier in containing the product. The invention utilizes a plurality of areas spaced apart longitudinally in the cavity for selectively placing protective plugs at each end of the implement such that one packaging cavity may be used for various lengths of implements. The protective plugs prevent the implement from penetrating the ends of the cavity which would break the sterile barrier.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
186 words
A storage container for rigid elongated surgical implements which is suitable for pre-sterilized packaging comprising: (a) a bottom assembly containing an elongated cavity for receiving an implement wherein said cavity has a first end and a second end; (b) a plurality of areas at the first end of said cavity spaced apart longitudinally from each other and capable of containing a protective plug, such that the plug will be retained in the area in the bottom assembly upon dispensing of the product from the container; (c) at least one protective plug for selectively positioning in at least one of said areas in order to selectively accommodate various length implements in the cavity, while restricting the amount of longitudinal movement of the implement in the cavity and protecting the implement from hitting the end of the cavity, each said plug being made of any suitable material soft enough not to damage the surgical implement, yet rigid enough not to generate particulate flakes onto the surgical implement; and (d) a lid portion capable of being sealed to the bottom assembly to retain the implement until ready for dispensing.
Claim 2
Dependent Claim
186 words
A storage container for rigid elongated surgical implements which is suitable for pre-sterilized packaging comprising: (a) a bottom assembly containing an elongated cavity for receiving an implement wherein said cavity has a first end and a second end; (b) a plurality of areas at the first end of said cavity spaced apart longitudinally from each other and capable of containing a protective plug, such that the plug will be retained in the area in the bottom assembly upon dispensing of the product from the container; (c) at least one protective plug for selectively positioning in at least one of said areas in order to selectively accommodate various length implements in the cavity, while restricting the amount of longitudinal movement of the implement in the cavity and protecting the implement from hitting the end of the cavity, each said plug being made of any suitable material soft enough not to damage the surgical implement, yet rigid enough not to generate particulate flakes onto the surgical implement; and (d) a lid portion capable of being sealed to the bottom assembly to retain the implement until ready for dispensing.
Claim 3
Dependent Claim
52 words
A container as defined in claim 1 wherein the second end of said cavity of the bottom assembly further includes at least one area capable of containing a protective plug, and includes at least one additional plug for positioning in said at least one area at the second end of the cavity.
Claim 4
Dependent Claim
42 words
A container as defined in claim 1 wherein the bottom assembly is a thin flat sheet of material with one or more integral cavities depressed into the material and wherein said cavities are conformed to the general shape of the product contained.
Claim 5
Dependent Claim
32 words
A container as defined in claim 1 wherein said cavity is long and thin and substantially cylindrical in shape with one longitudinal side of the cylindrical shape open to receive an implement.
Claim 6
Dependent Claim
39 words
A container as defined in claim 1 or 2 wherein said protective plugs and the areas for containing said plugs are of a corresponding mating shape suitable for a snap-lock fit to maintain the plugs securely in the areas.
Claim 7
Dependent Claim
70 words
A container as defined in claim 5 wherein said snap-in plugs are substantially cylindrical in shape and wherein said areas for snap-in plugs are substantially cylindrical in shape with one side of the cylindrical shape of the area open for receiving the plug and at least more than half of a cylindrical shape present in the area to allow for the substantially cylindrical plug to be snapped into the area.
Claim 8
Dependent Claim
21 words
A container as defined in claim 1 wherein said areas for protective plugs are larger in diameter than the overall cavity.
Claim 9
Dependent Claim
22 words
A container as defined in claim 1 wherein the bottom assembly is fabricated from any thermoformable plastic material adaptable to sterile packaging.
Claim 10
Dependent Claim
50 words
A container as defined in claim 1 wherein the lid portion is made of any heat sealable material in the shape of a thin, flat, sheet which is heat sealed to the bottom assembly and which can act as a sterile barrier in containing a product in a sterile environment.
