Abstract
A container for a composition made of multiple components includes an outer housing having a chamber and an inner housing having a compartment. The inner housing includes a frangible wall portion that, when ruptured, enables the components to contact each other for mixing. Advantageously, the inner housing can be manufactured separately from the outer housing, and the housings can be assembled during a subsequent operation. In certain embodiments, the inner housing is slidable relative to the outer housing from a first position to a second position, and during the sliding movement a puncturing tool located within the container breaks the frangible wall portion and causes the components to contact each other.
Claims31
A container for a composition made of two or more components comprising:
- an outer housing having a chamber;
- an inner housing having a compartment, the inner housing including a frangible wall portion and a first opening spaced from the frangible wall portion;
- a cover extending across the first opening;
- a first component received in the chamber;
- and
- a second component received in the compartment, wherein the inner housing is received in the outer housing, and wherein the first component contacts the second component when the frangible wall portion is ruptured.
A container for a composition made of two or more components comprising:
- an outer housing having a chamber and a puncturing tool;
- an inner housing slidably received in the chamber of the outer housing, the inner housing having a compartment with a frangible wall portion;
- a first component received in the chamber;
- and
- a second component received in the compartment,
- wherein the inner housing is slidable in the chamber from a first position where the frangible wall portion is spaced from the puncturing tool to a second position where the frangible wall portion is ruptured by the puncturing tool such that the first component and the second component come into contact with each other.
