  • Patent number: 4519774
    Abstract: A low cost igniter comprising a multi capsule of low strength, non-porous material, such capsule being divided into at least two separate compartments. One of such compartments is filled with a freezable fluid, and another contains an ingredient that will function in the presence of a selected ingredient to bring about combustion. The ingredient in the capsule is disposed in the immediate vicinity of the second ingredient, so that on the occasion of a freezing temperature, the freezable fluid in the compartment of the capsule will freeze and expand, fracturing all components of the capsule substantially simultaneously, thus leading to a combination of the first and second ingredients, as will bring about immediate combustion. When the multi capsule is configured to have two compartments, the second ingredient is contained adjacent the capsule, but when the multi capsule has three compartments, the freezable fluid as well as both ingredients are each sealed in separate compartments of such capsule.
