ABSTRACT:
A device for joining a first container to a second container to be inserted into the chamber of a weapon includes a first neck disposed adjacent a first face of the first container, a second neck disposed adjacent a second face of the second container and a deformable ring. The first container and the second container have container diameters that are less than a chamber diameter D1. The first face of the first container is alignable with a second face of the second container along a longitudinal axis. The second neck includes a circular cusp. The deformable ring is disposed around the first neck and includes an annular lip. The deformable ring is shaped to slide substantially parallel to the longitudinal axis toward the second container to engage the cusp. The deformable ring has a ring diameter D3 that is greater than the chamber diameter D1. The deformable ring is configured to decrease in diameter under deformation from the ring diameter D3 to the chamber diameter D1 when the first container is inserted into the chamber. As a result, the deformable ring disengages from the cusp and allows the first container to separate from the second container without requiring use of tools or manipulation by the operator.
