Blow fill sealed container with twist off top operated by overcap and method of forming the same
View Patent ↗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.
1. 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 positioned over the first frangible seal and sealed to the container body to provide a sterile barrier surrounding the first frangible seal;
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 broken by manually depressing the upper cap toward the container body.
2. The container assembly of claim 1 , wherein the upper cap is attached to the closure top after the second frangible seal is broken by depressing the upper cap toward the container body.
3. The container assembly of claim 1 , wherein the overcap includes a detent portion for securing the closure top to the overcap once the second frangible seal is broken.
4. The container assembly of claim 3 , wherein the overcap and secured closure top are removable from container body by twisting the overcap to break the first frangible seal.
5. The container assembly of claim 3 , wherein the detent portion frictionally attaches the closure top to the overcap.
6. A container assembly for use with a needleless syringe having
a luer end, comprising;
a container body adapted to contain fluid, including a port having an aperture therein adapted for use with a luer end of a syringe;
a closure top attached over the aperture of the container body with a first frangible seal; and
an overcap including a detent portion for associating 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;
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 broken by manually depressing the upper cap toward the container body.
7. The container assembly of claim 6 , wherein the upper cap is attached to the closure top after second frangible seal is broken by depressing the upper cap toward the container body.
8. 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 positioned over the first frangible seal and hermetically sealed to the container body to provide a sterile barrier surrounding the first frangible seal;
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.
