Container with pierceable and/or collapsible features
First Claim
1. A pierceable, unitary, molded container having a peripheral parting line that delineates opposing portions of the container and comprising:
- a hollow body portion defining an access port and suitable for containing a substance to be drained therefrom;
a unitary sealing wall coextensive with and sealing said access port;
a pierceable membrane in said sealing wall; and
said sealing wall defining guide surfaces that converge toward said pierceable membrane and define to one side of said parting line a recess for receiving a piercing spike means therewith.

Abstract
A hermetically sealed package is provided for the administration of a solution or other liquid to a patient. The package includes a blow molded container, cap, and releasable cover. The cap accommodates piercing of the cap and container with a draining spike. The cap has one or more self-closing seals or liners and can be disposed on the container so as to permit penetration of the cap and container by a piercing spike without contacting the parting line of the molded container. The cap includes a special structure for guiding the spike at the initiation of the piercing process, and the cap has an improved structure for sealingly engaging the spike upon insertion. As the container is drained, one of the container walls collapses toward the other to facilitate the draining process and provide a convenient shape for subsequent handling and storage.

5. A sealed but pierceable package comprising:
-
a molded container having a peripheral parting line that delineates opposing portions of the container and an access port thereto defined by a boss unitary with said container and sealed by a unitary pierceable membrane; a cap secured to said boss over said membrane, said cap including a pierceable, resilient, self-sealing liner juxtaposed over said container membrane; and said self-sealing liner including an exposed target surface and a deformable interior surface facing toward said pierceable membrane to one side of said parting line, said deformable interior surface defining a recess aligned with said exposed target surface and providing an inwardly enlarging passageway for a piercing spike while supplying increased resistance against removal of said piercing spike when inserted through said target surface. - View Dependent Claims (6, 7, 8)

9. A pierceable package comprising:
-
a molded container having an access port thereto defined by a boss unitary therewith and sealed by a unitary pierceable membrane and having a peripheral parting line that delineates opposing portions of the container; a cap mounted on said boss over said membrane and including a pierceable, resilient, self-closing seal in registry over an area of said container membrane to one side of said parting line, said cap including a housing that is substantially more rigid than said seal and that encloses said seal while exposing at least one pierceable target region of the seal, said housing being secured to said container boss to retain said seal in position and including an annular, raised rim around said seal target region; and a removable cover releasably sealed to said housing rim over said self-closing seal to isolate said seal target region from the ambient atmosphere. - View Dependent Claims (10)
