Abstract
Abstract A composite medicament container including a vial to contain a dry powdered medicament, an outlet opening in the vial, a Lyo-stopper closing and sealing the outlet opening, and a flexible liquid container to contain a diluent for the dry medicament. The liquid container has a discharge port having an ellipsoidal shape. There is a closure plug in the discharge port. The closure plug has an ellipsoidal configuration and a size to mate with the interior of the discharge port and be secured therein. The configurations and sizes of the discharge port and said closure plug co-act to provide an enlarged, closely contacting extensive scaling area. The vial opening has a circular external configuration so that the vial outlet opening and the liquid container closure plug are mateable. Also included is a composite interengaging and sealing means which is operatively attaching and sealing the containers in mated relationship for intermixing the materials therein.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
214 words
A composite medicament container comprising a first vial member for a first component of the medicament, an outlet opening in the vial, a closure member slidably mounted in said outlet opening for normally sealing said outlet opening, a flexible container member having a discharge outlet fitting with a port and a plug member for the port, means mounting said closure and plug members so that the outlet opening and port are axially aligned and plunger rod means disposed completely interiorly of said flexible container member cooperatively associated with said closure and plug members actuatable axially to a discharge position to displace said closure and plug members into said first vial member and thereby establish fluid communication between said first and second members, guide means for guiding said plunger rod means during actuation thereof axially to said discharge position, said plunger rod means being of a cross-sectional configuration to permit fluid flow around the periphery of said plunger rod whein in said discharge position, the diameter of said closure member being greater than the diameter of said plug member and said plunger rod manipulatable externally of said flexible container to actuate the same axially and engageable with said plug member to ensure displacement of both said closure and plug member into said first vial member.
Claim 2
Dependent Claim
214 words
A composite medicament container comprising a first vial member for a first component of the medicament, an outlet opening in the vial, a closure member slidably mounted in said outlet opening for normally sealing said outlet opening, a flexible container member having a discharge outlet fitting with a port and a plug member for the port, means mounting said closure and plug members so that the outlet opening and port are axially aligned and plunger rod means disposed completely interiorly of said flexible container member cooperatively associated with said closure and plug members actuatable axially to a discharge position to displace said closure and plug members into said first vial member and thereby establish fluid communication between said first and second members, guide means for guiding said plunger rod means during actuation thereof axially to said discharge position, said plunger rod means being of a cross-sectional configuration to permit fluid flow around the periphery of said plunger rod whein in said discharge position, the diameter of said closure member being greater than the diameter of said plug member and said plunger rod manipulatable externally of said flexible container to actuate the same axially and engageable with said plug member to ensure displacement of both said closure and plug member into said first vial member.
Claim 3
Dependent Claim
34 words
A composite medicament container as claimed in claim 1, wherein said plug member is of a smaller diameter than said closure member to allow for axial displacement of both members into said first vial.
Claim 4
Dependent Claim
30 words
A composite medicament container as claimed in claim 1, wherein said outlet in said first vial has a circumferentially extending indentation providing a seat and seal for the closure member.
Claim 5
Dependent Claim
41 words
A composite medicament container as claimed in claim 1, including a rigid discharge fitting for the discharge port of said flexible container which confronts the outlet of said first vial and seal means between said discharge fitting and said first vial.
Claim 6
Dependent Claim
35 words
A composite medicament container as claimed in claim 4, wherein said discharge fitting and said first vial have radially outwardly projecting flanges and a one-piece member securing the vial member and container by said flanges.
Claim 7
Dependent Claim
33 words
A composite medicament container as claimed in claim 1, wherein said plunger rod is of cross section different than said port cross section to allow flow between said plunger rod and said port.
Claim 8
Dependent Claim
34 words
A composite medicament container as claimed in claim 1, including means mounting said plunger rod for limited axial movement in said port in a predetermined manner preventing full displacement thereof into said flexible container.
Claim 9
Dependent Claim
43 words
A composite medicament container as claimed in claim 7, wherein said port is of stepped configuration defining a shoulder along its length and wherein said plunger rod has an enlarged portion engageable with said shoulder to limit axial movement of said plunger rod.
