Abstract
Abstract A double-chambered cylindrical vial for separately containing co-reactive materials is composed of a closed capsule having a fitst storage chamber for one of the co-reactants and a rupturable chamber located adjacent one of the ends of said capsule. The capsule end is characterized by a corridor therein closed to the first chamber by a rupturable wall or membrane. The capsule is activated by inserting into said corridor a pin or piston of sufficient diameter to close the corridor and which ruptures the second chamber thereby expelling all of the contents of said second chamber into the first chamber thus permitting the co-reaction of the materials.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
134 words
A container for carrying mutually reactive materials comprising a first chamber, at least a first end cap having a corridor therein, said corridor adapted to communicate with said first chamber and the exterior of said container; a first and second rupturable membrane defining a second chamber therebetween within said corridor; said second membrane next adjacent said first chamber covering substantially the entire end wall of said end cap, said second membrane being held against the end wall of said end cap by a substantially rigid disc in frictional contact with the side walls of said end cap; piercing means adapted to rupture said membranes displacing the contents of said second chamber and expelling said contents into said first chamber; said piercing means further adapted to close said corridor subsequent to rupture of said membranes.
Claim 2
Dependent Claim
134 words
A container for carrying mutually reactive materials comprising a first chamber, at least a first end cap having a corridor therein, said corridor adapted to communicate with said first chamber and the exterior of said container; a first and second rupturable membrane defining a second chamber therebetween within said corridor; said second membrane next adjacent said first chamber covering substantially the entire end wall of said end cap, said second membrane being held against the end wall of said end cap by a substantially rigid disc in frictional contact with the side walls of said end cap; piercing means adapted to rupture said membranes displacing the contents of said second chamber and expelling said contents into said first chamber; said piercing means further adapted to close said corridor subsequent to rupture of said membranes.
