Closure assembly
First Claim
1. A closure assembly for a medical device having an access portion with a discharge port, said closure assembly comprising:
- a closure cap including an access engaging portion removably connectible in flow restricting relation to the discharge port,a connecting structure mounted on said access engaging portion and disposed and configured to define an interactive engagement with an attachment structure of the access portion,said interactive engagement comprising an at least partial push-on connection of said closure cap to the access portion,said interactive engagement further comprising a rotate-off disconnection of said closure cap from said access portion,said connecting structure comprising a segmented thread structure formed on an exterior of said access engaging portion, said segmented thread structure having a predetermined configuration,said segmented thread structure comprising a plurality of spaced apart protrusions, andsaid segmented threaded structure further comprising at least an outer thread section and an inner thread section;
said outer thread section cooperatively dimensioned with the attachment structure to facilitate an axial, linear movement and overlapping, sliding engagement therebetween;
said axial, linear movement at least partially defining said push-on connection.

Abstract
A closure assembly for a syringe having a nozzle or access portion and a discharge port including a closure cap or syringe cap having a access engaging portion removably connectible in flow restricting relation to the discharge port. A connecting structure is mounted on the access engaging portion and disposed and configured to define an interactive engagement with an attachment structure of the nozzle or access portion of the syringe. Structural and operative features of the connecting structure enable a “push-on connection” of the closure cap or syringe cap to the nozzle or access portion and a “rotate-off disconnection” of the closure cap or syringe cap from the nozzle or access portion. The closure cap or syringe cap may be used independently of or in combination with an end cap and an included indicator member, wherein the combination closure cap or syringe cap and end cap define a tamper evident cap for the syringe.

24. A closure assembly for a medical device having an access portion with a discharge port, said closure assembly comprising:
-
a closure cap including an access engaging portion removably connectible in flow restricting relation to the discharge port, a connecting structure mounted on said access engaging portion and disposed and configured to define an interactive engagement with an attachment structure of the access portion, said interactive engagement comprising an at least partial push-on connection of said closure cap to the access portion, said interactive engagement further comprising a rotate-off disconnection of said closure cap from said access portion, and said access engaging portion comprising a flexible construction sufficient to accomplish a predetermined flexure thereof at least during said push-on connection;
said connecting structure movable with said access engaging portion during flexure thereof into connection with the attachment structure of the access portion during said push-on connection. - View Dependent Claims (25, 26, 27, 28, 29, 30)
