Abstract
Abstract A container for hypodermic syringes which provides a first, tamper-indicating sealed position for containing a sterilized syringe and a seocnd, lockingly closed position for storing and safely disposing of a used syringe is disclosed. The container includes an elongated hollow plastic tube having an integral end wall closing one end. The opposite open end of the tube flares out to form an enlarged cylindrical boss section. A concave plastic cap fits snugly over rear annular beads projecting readially outwards from the rear portion of the outer cylindrical wall of the boss. Ultrasonic welds between the outer circumferential surface of the rear annular beads, and the inner cylindrical surface of the cap are breakable by twisting the cap relative to the tube providing an audible and tactile indication that the container has not previously been opened. The cap has one or more axially disposed resilient tabs, each tab formed between a pair of slots extending axially inwards from the annular end wall of the cap. A larger diameter, front annular bead projecting radially outwards from the front portion of the boss section of the tube lockingly engages a groove in the inner surface of each resilient tab of the cap when the cap is pushed sufficiently far down on a tube, containing a used syringe, permitting the container and enclosed syringe to be safely transported to a disposal site.

The container of claim 2 wherein said locking fastening means is actuated by pushing said cap axially downward over said open end of said hollow body.
Claim 5
Dependent Claim
29 words
The container of claim 2 wherein said frangible fastening means provides a sound and vibration when broken, thereby providing an indication of said container not having been previously opened.
Claim 6
Dependent Claim
15 words
The container of claim 2 wherein said body and said cap are made of plastic.
Claim 7
Dependent Claim
20 words
The container of claim 5 wherein said frangible fastening means comprises a welded joint between said cap and said body.
Claim 8
Dependent Claim
113 words
A container for hypodermic syringes and the like having a first, tamper-indicating sealed position and a second, locking sealed position comprising: (a) an elongated, hollow cylindrical tube sealed at one end, and open at the other end, (b) a concave cap adapted to fit over said open end of said tube, (c) frangible fastening means joining the inner wall of said cap to the outer cylindrical wall of said tube, said frangible fastening means adapted to hold said cap in a first axial position relative to said tube, and (d) locking fastening means adapted to hold said cap in a second axial position relative to said tube after breaking said frangible fastening means.
Claim 9
Dependent Claim
113 words
A container for hypodermic syringes and the like having a first, tamper-indicating sealed position and a second, locking sealed position comprising: (a) an elongated, hollow cylindrical tube sealed at one end, and open at the other end, (b) a concave cap adapted to fit over said open end of said tube, (c) frangible fastening means joining the inner wall of said cap to the outer cylindrical wall of said tube, said frangible fastening means adapted to hold said cap in a first axial position relative to said tube, and (d) locking fastening means adapted to hold said cap in a second axial position relative to said tube after breaking said frangible fastening means.
Claim 10
Dependent Claim
35 words
The container of claim 7 wherein said locking fastening means comprises in combination at least one elastically deformable member on said cap and a member on said tube lockingly engageable with said elastically deformable member.
Claim 11
Dependent Claim
34 words
The container of claim 8 wherein said locking fastening means is actuated by pushing said cap axially downward over said open end of said tube to said second axial position relative to said tube.
Claim 12
Dependent Claim
