Container closure with a frangible seal and a connector for a fluid transfer device
First Claim
1. A closure for mounting across the mouth of a container and through which fluid can be transferred using a fluid transfer device, said closure comprising:
- a body to be disposed on said container across said container mouth to initially occlude said container mouth, said body defining a passage having an exterior opening to receive a fluid transfer device; and
a frangible seal initially extending across said passage to sealingly occlude said passage, said frangible seal including a generally flap-like transverse wall portion having a first peripheral section frangible connected to an adjacent region of said body and a second peripheral section defining a hinge connecting the transverse wall portion to the body, the frangible connection for the first peripheral portion constructed to be broken when engaged by a fluid transfer device to open the transverse wall portion about the hinge and establish fluid communication between the fluid transfer device and an interior of said container.

Abstract
A closure is provided for mounting across the mouth of a container and through which liquid can be withdrawn with a fluid transfer device having a male member. The closure includes a body for being disposed on the container across the container mouth. The body defines a passage with an exterior opening for matingly receiving the male member of the fluid transfer device. A frangible seal initially extends across the passage in the body to occlude the passage. The seal is broken when it is engaged by the male member of the fluid transfer device, thereby establishing fluid communication between the fluid transfer device and the interior of the container.

12. A closure for a container, said closure comprising:
-
a body to be disposed across a mouth of the container, said body defining a passage therethrough, said passage having an exterior opening to receive a fluid transfer device; and a frangible seal disposed across said passage of said body, said frangible seal fluidly sealing said passage, said frangible seal including a stress concentrator disposed on the frangible seal to concentrate force applied by a fluid transfer device received by said passage of said body and initiate breakage of the frangible seal. - View Dependent Claims (13, 14)

15. A container assembly for containing a product, the assembly comprising:
-
a container having a chamber defined therein, the container further defining a mouth in fluid communication with the chamber; and a closure mounted across the container mouth through which a product can be transferred using a transfer device, the closure including a body disposed across said container mouth, said body defining a passage having an exterior opening to receive a transfer device; and a frangible seal initially extending across said passage to sealingly occlude said passage, said frangible seal including a generally flap-like transverse wall portion having a first peripheral section frangibly connected to an adjacent region of said body and a second peripheral section defining a hinge connecting the transverse wall portion to the body, the frangible connection for the first peripheral portion constructed to be broken by a transfer device to open the transverse wall portion about the hinge and establish fluid communication between the transfer device and the chamber of said container. - View Dependent Claims (16, 17, 18, 19, 20)
