Abstract
Abstract A rigid packaging container assembly for protecting, and assisting the arming of a sealed prefilled syringe barrel and insertable needle assembly including a sheath surrounding the needle assembly, slidable on the barrel and having a shoulder which engages a portion of the needle assembly to permit the operator to grasp the sheath and fully insert the needle assembly from a partially inserted position, with a sheath retainer surrounding the sheath and having a plurality of shelf projections extending through openings in the sheath and engageable with the underside of the syringe barrel to limit sliding movement of the sheath retainer upwardly along the syringe barrel so that a cooperating cap insertable within the sheath retainer and engageable with a portion of the sheath prevents movement of the sheath when the syringe is in its packaged condition thereby preventing arming of the syringe until the cover or cap is removed. There are also provided a plurality of tabs extending from the sheath so that in the disassembled condition of the container with only the sheath surrounding the needle assembly, the syringe will not be permitted to roll on a supporting surface.

Claim 4
Dependent Claim
66 words
A sheath and cap assembly for a syringe of the type having a barrel, a connector and a needle assembly insertable in Said connector as defined in claim 2, wherein said sheath has a plurality of tabs extending radially outwardly and defining said sheath projection means, said cap having an end portion engageable with said tabs and selectively preventing movement of said sheath toward the barrel.
Claim 5
Dependent Claim
153 words
A sheath assembly for a syringe having a barrel and a self-connecting needle assembly, comprising: a sheath for said needle assembly, means on said sheath engageable with said needle assembly when in a partly inserted position in said barrel for moving said needle assembly to a fully inserted position, said sheath having openings therethrough exposing portions of said barrel, a sheath retainer engageable with and surrounding said sheath and having shelf projections extending through said openings and engageable with said barrel to limit axial movement of the sheath retainer to a position wherein the sheath does not insert the needle assembly, and other means selectively engageable with said sheath and said sheath retainer to prevent relative movement therebetween when the sheath is in a position where the needle assembly is partly inserted, said sheath having means engageable with said barrel to limit lateral movement of the barrel with respect to the needle assembly.
Claim 6
Dependent Claim
153 words
A sheath assembly for a syringe having a barrel and a self-connecting needle assembly, comprising: a sheath for said needle assembly, means on said sheath engageable with said needle assembly when in a partly inserted position in said barrel for moving said needle assembly to a fully inserted position, said sheath having openings therethrough exposing portions of said barrel, a sheath retainer engageable with and surrounding said sheath and having shelf projections extending through said openings and engageable with said barrel to limit axial movement of the sheath retainer to a position wherein the sheath does not insert the needle assembly, and other means selectively engageable with said sheath and said sheath retainer to prevent relative movement therebetween when the sheath is in a position where the needle assembly is partly inserted, said sheath having means engageable with said barrel to limit lateral movement of the barrel with respect to the needle assembly.
Claim 7
Dependent Claim
44 words
A sheath assembly for a syringe having a barrel and a self-connecting needle assembly as defined in claim 4 including means for rotatably aligning the openings and the shelf projections in response to axial movement of the sheath retainer with respect to the sheath.
Claim 8
Dependent Claim
77 words
A sheath assembly for a syringe having a barrel and a self-connecting needle assembly as defined in claim 4 wherein said sheath has a plurality of generally radially extending tabs for preventing rolling of the syringe with the sheath in position, said other means selectively engageable with the sheath and the sheath retainer being engageable with said tabs to prevent movement of said sheath relative to the barrel to prevent a full insertion of the needle assembly.
Claim 9
Dependent Claim
