Abstract

The novel combination comprising:

a container having a cylindrical neck of reduced cross-section terminating in an open end, said neck having a projection on its inner surface in proximity to said open end, and

a closure for said open end having a skirt portion receivable in said open end and a shoulder at its outer end adapted to move into abutting relationship with the end of said cylindrical neck, said skirt portion having a cut out adapted for receiving said projection on the inner surface of said neck to hold said shoulder in non-abutting relationship with the end of said neck, said closure including a central fluid passage and a transverse fluid passage in communication therewith, the ends of said transverse fluid passage being sealed by the inner surface of said neck when said closure is held in the non-abutting position by the engagement of said projection in said cut out, said engagement being adapted to be overcome by force applied to the end of said closure whereby said shoulder is brought into abutting relationship with the end of said neck and the transverse passage is moved out of said neck and into fluid communication with the interior of said container.

Claims

1. The novel container and closure combination comprising:

a container having a cylindrical neck of reduced cross-section with respect to the main body of the container and terminating in an open end, said neck having a projection on its inner surface in proximity to said open end, and

a closure for said open end having a skirt portion received in said open end and a shoulder at its outer end adapted to move into abutting relationship with the end of said cylindrical neck, said skirt portion having a cut out adapted for receiving said projection on the inner surface of said neck to hold said shoulder in non-abutting relationship with the end of said neck, said closure including a central fluid passage and a transverse fluid passage in communication therewith, the ends of said transverse fluid passage being sealed by the inner surface of said neck when said closure is held in the non-abutting position by the engagement of said projection in said cut out, said engagement being adapted to be overcome by force applied to the end of said closure whereby said shoulder is brought into abutting relationship with the end of said neck and the transverse passage is moved out of said neck and into fluid communication with the interior of said container, whereby a fluid pathway is provided from the interior of said container through said closure to the exterior.

2. The combination of claim 1 wherein the walls of said container are collapsible upon the application of squeezing force.

3. The combination of claim 1 wherein a spike having a sharpened outer end is carried by said central fluid passage of said closure and is adapted to be separated from said closure.

4. The combination of claim 3 wherein said outer end of said spike is covered by a protective cover.

5. The combination of claim 3 wherein said spike includes an airway.

6. The combination of claim 1, wherein the container contains a dry powdered medicament.

7. The combination of claim 6 wherein the medicament is thiopental sodium.
