  Blow fill sealed container with twist off top operated by overcap and method of making the sameUSPTO Application #: 20070095855Title: 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. (end of abstract) Agent: Brian R.

[0001] The present invention relates to the field of containers. More particularly this invention relates to a sterile container assembly for storing fluids, including but not limited to drugs, and transferring them to a needleless syringe. BACKGROUND OF THE INVENTION [0002] In the past, the general practice of surgeons or other medical practitioners using hypodermic syringes has been to transfer an injection solution to a syringe from ampoules or vials holding a single dose. These ampoules have been adapted to be sealed by a non-resealable cap. The ampoule is opened by rocking the non-resealable cap, tearing the non-resealable cap from an outlet of the ampoule at an area of weakness. [0003] The outlets of these ampoules are often designed to mate with the open end of a needleless syringe. The open ends of needleless syringes come in several different forms or shapes. The two most popular forms of needle fitting are the friction fit fitting (such as the luer slip fitting) and the combination of screw thread and friction engagement fitting (such as the luer lock fitting). Ampoules with outlets that are designed to mate with luer slip fittings and ampoules with outlets that are designed to mate with luer lock fittings are known. [0004] It will be appreciated that this past practice has required separate sterilizing measures, as solution transfer for injecting into humans requires scrupulous sterilizing of components. [0005] Prior solutions for keeping these ampoules sterile include utilization of blister packaging of the ampoules prior to sterilization. This blister packaging is both costly and difficult to remove. [0006] Other types of conventional containers have a cover that the user turns to engage the cap and tear the cap from the container. None of these containers are adapted to operate with a needleless syringe. Further, none of these containers are particularly well adapted to prevent compromise or contamination of the sterile port of the container during the manual manipulation required to open the port. [0007] Therefore, a principal object of this invention is to provide a container assembly that maintains a sterile attachment zone for a needleless syringe. [0008] Another object of the invention is to provide a container assembly that has a guarded sterile syringe attachment zone, which is easily compromised during the manual manipulation, required to open the container assembly. [0009] Another object reduces risk of contamination of its opened port by finger touches. [0010] Another object of the invention is to provide a container assembly adapted for use with a needleless syringe and which includes an overcap to facilitate removal of a closure top from the container. [0011] A further object of the invention is to provide an overcap with an improved detent portion for engaging the closure top of a container. [0012] These and other objects will be apparent to those skilled in the art. SUMMARY OF THE INVENTION [0013] A container assembly includes a container body having a port adapted for use with a luer end of a needleless syringe. A first frangible seal seals the aperture to a closure top. 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. Depressing the upper cap toward the container body breaks the second frangible seal. 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. After removal, the top remains frictionally retained in the upper cap by the detent portion.
