Abstract:
A cartridge for holding a first and a second fluid, comprising:an outer capsule containing the first fluid;an inner capsule enclosed within the outer capsule and having a portion attached to a portion of an inner surface of the outer capsule, the inner capsule containing the second fluid;a self sealing perforatable section disposed on the outer capsule; anda perforatable section disposed on the inner capsule and generally aligned with the self sealing perforatable section of the outer capsule, whereby the concentration of the second fluid in the inner capsule increases the shelf life of the second fluid, relative to the shelf life of a mixture of the first fluid and the second fluid, while the outer capsule and the first fluid act as a protective layer to cause the second fluid to be mixed with the first fluid to form a non hazardous mixture in the event of an accidental rupture of the inner capsule, thus increasing the variety of fluids, and associated shelf lives, that can be stored or transported.
