Abstract
A closure assembly/container combination for delivering media fluid to a patient by needleless access means. The closure assembly comprises an elastomeric stopper for sealing the container at its open end and a spike access means equipped with a luer connector.
Claims20
A closure assembly/container combination, wherein said container contains a medical fluid therein, and said closure assembly having a needleless access means allowing withdrawal of said medical fluid from the container by the use of an intravenous tubing attached to said needlesless access means, said closure/container combination comprising:
- a container (a);
- a closure (b);
- and
- a cap (c),
- wherein said container (c) containing a medical fluid therein, having a neck portion terminating in an open end;
- wherein said closure assembly (b) inserted into the open end of said container, comprising:
- (1) an elastomeric stopper for hermetically sealing the container at its open end;
- (2) a cylindrical collar fastened over portions of the elastomeric stopper and the container, said cylindrical collar having a central opening in its flat top portion to allow access to a spike access means located in the elastomeric stopper;
- (3) a spike access means, located in the upper center portion of said elastomeric stopper, comprising:
- (I) a spike housing defined by a cylindrical side wall, a horizontal stopper membrane forming the bottom of the spike housing, and a removable sterility seal on the horizontal top portion of the spike housing;
- (ii) a spike, located in said spike housing, comprising:
- a top portion, a side portion, and a bottom portion;
- said top portion having a male element on the upper end thereof, a cylindrical shaft extending through the male element thereon, a cylindrical shaft extending through the male element having a fluid communicating channel therein and terminating in a sharp tip at the other, bottom end thereof for piercing the membrane area in said elastomeric stopper;
- (iii) A male connector on the exterior of the spike housing;
- said male element on the upper end of the spike and said male connector on the exterior of the spike housing being designed to twistably engage a female coupling to force and move the spike towards and penetrate the horizontal stopper membrane and thereby establish fluid communication with the medical fluid contained in said container;
- and wherein said cap (c) is covering the cylindrical collar over the container.

- a container (a);
- a closure assembly (b);
- and
- a cap (c) wherein said
- (a) container having a medical fluid therein, comprises:
- a neck portion having an interior radial surface and a transverse end surface forming the mouth of said container,
- an exterior surface which, with said transverse end surface, forms a radial ring to receive and hold a cylindrical collar,
- (b) a closure assembly inserted into the mouth of said container comprising:
- an elastomeric stopper (1), a cylindrical collar (2) and a spike access means (3), wherein said
- (1) elastomeric stopper comprises:
- a head portion and a skirt portion,
- said head portion having:
- a flange extending laterally outwardly form said skirt portion and is designed to cover the mouth of the container;
- and a recessed open central area designed to receive said spike access means;
- and
- said skirt portion projecting into the container sealing the medical fluid contained therein;
- (2) cylindrical collar comprising:
- a flat top portion having a central opening therein superimposed on the recessed open area in the head portion of the elastomeric stopper;
- a cylindrical side portion having an inner wall,
- an outer wall, and
- a bottom portion;
- said inner wall having an inwardly projecting ring positioned below the exterior radial ring on the container to securely hold the elastomeric stopper in the container;
- (3) spike access means located in the upper center portion of said elastomeric stopper, comprises:
- (i) a spike housing defined by a cylindrical side wall, a horizontal stopper membrane forming the bottom of the spike housing, a horizontal sterility seal covering the stopper membrane on the underside of the stopper membrane forming a barrier between the stopper membrane and the medical fluid in the container and a removable sterility seal on the horizontal top portion of the spike housing;
- (ii) a spike, located in said spike housing, comprises:
- a top portion, a side portion, and a bottom portion;
- said top portion having a male element thereon, a cylindrical shaft extending through the male element having a fluid communicating channel therein and terminating in a sharp tip at the other, bottom end thereof for piercing the membrane area in said elastomeric stopper;
- said side portion on the upper part thereof having a slidable plunger pressing against internal cylindrical wall of a male connector;
- (iii) a male connector on the exterior of the spike housing;
- said male element on the upper end of the spike and said male connector on the exterior of the spike housing being designed to twistably engage a female coupling to force and move the spike towards and penetrate the horizontal stopper membrane and the sterility seal and thereby establish fluid communication with the medical fluid contained in said container;
- and
- (c) cap enclosing the elastomeric stopper, the cylindrical collar and spike access means to maintain the closure assembly free form contamination.
