Abstract
A closure and method of making a closure are disclosed. The closure includes a cap body having a top portion and an opening extending therethrough defining a cavity in communication with said opening. A flow channel is defined within a portion of the cap body having an inlet and an outlet. A stopper is disposed within the cavity adjacent the outlet of the flow channel. The stopper is formed from a material adapted for flowing through the flow channel to form a pierceable portion, with at least one of the cap body and the stopper configured for closing a container.
Claims43
A closure, comprising:
- a closure assembly for closing and sealing a container, the closure assembly comprising:
- a cap body defining a permanent cavity therethrough and having a top portion defining an opening, the cavity in fluid communication with the opening, and a portion of the cap body defining a flow channel having an inlet and an outlet;
- and
- a stopper disposed within the cavity adjacent the outlet of the flow channel, the stopper having a pierceable portion formed of a material, wherein the material is adapted to flow through the flow channel of the cap body to form the pierceable portion.
A closure, comprising:
- a closure assembly for closing and sealing a container, the closure assembly comprising:
- a cap body having a top portion defining an opening extending therethrough;
- an external annular skirt depending from an outer perimeter of the top portion;
- an internal annular skirt depending from an inner portion of the top portion adjacent the opening, the internal annular skirt defining a permanent cavity in fluid communication with the opening in the top portion, and a portion of the internal annular skirt defining a flow channel having an inlet adjacent the top portion and an outlet;
- and
- a stopper disposed within the cavity adjacent the outlet of the flow channel, the stopper having a pierceable portion formed of a material, wherein the material is adapted to flow through the flow channel of the cap body to form the pierceable portion.
A container assembly comprising:
- a collection container having a closed bottom, an open top portion, and a sidewall extending therebetween, adapted to receive a specimen sample therein;
- and
- a closure assembly for closing and sealing the open top portion of the collection container, the closure assembly comprising:
- a cap body defining a permanent cavity therethrough and having a top portion defining an opening, the cavity in fluid communication with the opening, and a portion of the cap body defining a flow channel having an inlet and an outlet;
- and
- a stopper disposed within the cavity adjacent the outlet of the flow channel, the stopper having a pierceable portion formed of a material, wherein the material is adapted to flow through the flow channel of the cap body to form the pierceable portion.
