Pull cap for a port of an administration assembly

Abstract

A cap is provided for covering a port of a fluid administration assembly. The cap comprises a top wall, a side cylindrical wall defining an opening into which said port can be inserted, and an inside surface of the top and side wall which defines a chamber. The cap further comprises a handle extending from said top wall and a plug extending from the inside surface of said top wall within said chamber.

We claim:  
     
         1 . A cap for covering a port of a fluid administration assembly, said cap comprising: 
 a top wall, a side cylindrical wall, and an opening defined by said side wall for receiving said port; said top and side wall define a chamber which communicates with said opening;    a handle extending from said top wall; and    a solid plug extending from the said top wall within said chamber.    
     
     
         2 . The cap of  claim 1  wherein said handle is offset from the center of said top wall.  
     
     
         3 . The cap of  claim 2  wherein said handle extends along the edge of said top wall and has an arcuate shape.  
     
     
         4 . The cap of  claim 1  wherein said side wall has an inner diameter less than the outer diameter of said port.  
     
     
         5 . The cap of  claim 1  wherein said cap is made of a flexible material.  
     
     
         6 . The cap of  claim 5  wherein said material is silicone rubber.  
     
     
         7 . The cap of  claim 1  wherein said plug is generally cylindrically shaped.  
     
     
         8 . The cap of  claim 1  wherein said plug is constructed to fit easily within said port, but provide support during sterilization.  
     
     
         9 . The cap of  claim 1  wherein said plug has an outer surface, said plug outer surface and an inside surface of side wall define an open annular channel therebetween for receiving a wall of said port.  
     
     
         10 . The cap of  claim 7  further comprising an annular pocket defined by said inside surface of said side wall, top wall and outer surface of said plug, said pocket communicating with said open annular channel.  
     
     
         11 . The cap of  claim 8  wherein said pocket is rectangularly shaped in cross.  
     
     
         12 . The cap of  claim 1  wherein said plug extends beyond the end of said side wall.  
     
     
         13 . An administration assembly including: 
 a container filled with fluid;    a port assembly connected to said container for administering fluid from said container, said port assembly including a cylindrical port; and    a flexible cap for covering said cylindrical port, said cap comprising: 
 a top wall, side cylindrical wall extending therefrom and an opening defined by side wall for receiving said port;  
 a handle extending from said cap; and  
 a solid plug extending from the inside surface of said top wall, said plug adapted for insertion into said opening of said port.  
   
     
     
         14 . The assembly of  claim 13  wherein said top and side wall have an inside surface, said inside surface of said side wall and plug define an open annular channel therebetween.  
     
     
         15 . The assembly of  claim 13  wherein said cap further comprising an annular pocket defined by said inside surface of said top wall, said side cylindrical wall and outer surface of said plug, said pocket communicating with said annular chamber.  
     
     
         16 . A cap for covering the administration port on a container, said cap comprising: 
 a top wall, a side cylindrical wall, and an opening defined by said side wall into which said port can be inserted;    a handle extending from said top wall;    a plug extending from said top wall, said plug adapted to be inserted into said port;    a pocket with said chamber defined by said plug, said side cylindrical wall and said top wall.    
     
     
         17 . The assembly of  claim 13  wherein the port is made of polypropylene.  
     
     
         18 . The cap of  claim 1  wherein said port is made of a material that is deformable under heat.  
     
     
         19 . The cap of  claim 16  wherein said plug is solid.  
     
     
         20 . The assembly of  claim 13  wherein said port and cap can be sterilized and can maintain sterility therebetween until the cap is removed.  
     
     
         21 . The assembly of  claim 13  wherein said handle is positioned to provide a firm but comfortable removal force.  
     
     
         22 . The assembly of  claim 13  wherein said port is adapted to receive a piercing pin therein.  
     
     
         23 . The assembly of  claim 15  wherein the pocket is adapted to enable the port to deform during sterilization whereby the deformation provides tamper evidence.  
     
     
         24 . The cap of  claim 18  wherein the material is polypropylene.  
     
     
         25 . The assembly of  claim 13  wherein said port is made of a material that is deformable under heat.  
     
     
         26 . The assembly of  claim 25  wherein said material is polypropylene.
