Pierceable cap having piercing extensions for a sample container
First Claim
1. A pierceable cap comprising:
- a shell,an access port in the shell for allowing passage of at least part of a transfer device through the access port, wherein the transfer device transfers a sample specimen,a frangible layer disposed across the access port for preventing transfer of the sample specimen through the access port prior to insertion of the at least part of the transfer device,a peripheral groove for securing the frangible layer within the shell,one or more extensions proximate to the frangible layer, wherein the one or more extensions are coupled to the shell at one or more coupling regions, andwherein the one or more extensions rotate around the one or more coupling regions and pierce the frangible layer upon application of pressure from the transfer device.

Abstract
A pierceable cap may be used for containing sample specimens during storage and transport. The pierceable cap may prevent unwanted escape of sample specimen before transfer with a transfer device. The pierceable cap may fit over a vessel. An access port in the pierceable cap may allow passage of a tip of a transfer device though the pierceable cap. A frangible layer may be disposed across the access port. One or more extensions proximate to the frangible layer may be coupled to the pierceable cap by coupling regions or other similar devices. The one or more extension may rotate around the one or more coupling regions during insertion of the transfer device. The movement of the one or more extensions may pierce the frangible layer to create airways and allow air to escape from a vessel at a reduced velocity.

28. A pierceable cap comprising:
-
a shell, an access port through the shell, one or more extensions having a proximate end coupled to walls of the access port by one or more coupling regions and a distal end extending into the access port, wherein the distal end of the extensions are movable, in response to pressure from a transfer device disposed in the access port, from a first position to a second position, a frangible layer within the access port proximate to the one or more extensions, wherein the distal end of the extensions, in the second position, pierce the frangible layer, wherein the frangible layer comprises pre-formed scoring.

29. A pierceable cap comprising:
-
a shell, an access port in the shell for allowing passage of at least part of a transfer device through the access port, wherein the transfer device transfers a sample specimen, a frangible layer disposed across the access port for preventing transfer of the sample specimen through the access port prior to insertion of the at least part of the transfer device, wherein the frangible layer further comprises pre-formed scoring, one or more extensions proximate to the frangible layer, wherein the one or more extensions are coupled to the shell at one or more coupling regions, and wherein the one or more extensions rotate around the one or more coupling regions and pierce the frangible layer upon application of pressure from the transfer device.
