Blow fill sealed container with twist off top operated by overcap and method of making the same

Abstract

A container assembly includes a container body having a port or aperture adapted for use with a luer end of a needleless syringe. The aperture is sealed to a closure top by a first frangible seal. An overcap has a cap base sealed to the container body and an upper cap connected to the cap base by a second frangible seal, providing a sterile barrier surrounding the first frangible seal. The second frangible seal is broken by depressing the upper cap toward the container body. Alternatively, the second frangible seal is a removable tear strip broken by tugging on the tear strip. The upper cap includes a detent portion frictionally securing the upper cap to the closure top when the upper cap is depressed toward the container body. The upper cap and secured closure top are removed from container body by twisting the upper cap to break the first frangible seal and open the port.

         21 . A container assembly, comprising: 
 a container body adapted to contain fluid, including a port having an aperture therein;    a closure top attached over the aperture of the container body with a first frangible seal; and    an overcap including a detent portion frictionally attaching the overcap to the closure top to allow a user to break the first frangible seal and remove the closure top by twisting the overcap,    the detent portion includes planar finger elements extending downwardly from an end of the overcap and around the closure top, each finger element including a finger shoulder mateable with a corresponding tang shoulder on the closure top for frictionally attaching the closure top to the overcap.    
     
     
         22 . The container assembly of  claim 21 , wherein the overcap is positioned over the first frangible seal and sealed to the container body to provide a sterile barrier surrounding the first frangible seal.  
     
     
         23 . The container assembly of  claim 22 , wherein the overcap includes a cap base sealed to the container body and an upper cap connected to the cap base by a second frangible seal, the second frangible seal is a removable tear strip, and the second frangible seal is broken by manually tugging on the tear strip to break the second frangible seal and sever the upper cap from the container body.  
     
     
         24 . The container assembly of  claim 23 , wherein the detent portion of the upper cap is attached to the closure top after the tear strip is removed by depressing the upper cap toward the container body.
