Benefits of technology

0032] The foregoing and other aspects of the invention will become more apparent from the following description of specific embodiments thereof and the accompanying drawings which illustrate, b

Problems solved by technology

The substances in the multi-compartment bag are separated by two breakable walls and a third compartment which together act as a barrier to migration of one substance into the second substance, which would reduce the shelf life and efficiency of the hot or cold chemical pack.

Embodiment Construction

[0052] The description which follows, and the embodiments described therein, are provided by way of illustration of an example, or examples, of particular embodiments of the principles of the present invention. These examples are provided for the purposes of explanation, and not limitation, of those principles and of the invention. In the description which follows, like parts are marked throughout the specification and the drawings with the same respective reference numerals.

[0053] Briefly, the heating / cooling element of the embodiment includes a triggering mechanism attached adjacent a frangible seal between sealable envelopes containing agents or attached to each envelope containing agents. The triggering mechanism may provide complete, uniform breakage of the frangible seal as opposed to the rupturable or squeezable counterpart of the prior art which usually breaks at a point. This enables quicker and more complete mixing of chemicals in the embodiment and may increase the size o...

Abstract

A package is provided including a first sealable envelope containing a first agent, a second sealable envelope containing a second agent adjacent the first sealable envelope and a frangible seal separating the first sealable envelope from the second sealable envelope and a triggering mechanism located on an exterior of the package, the triggering mechanism having a first portion attached to the package at a first point adjacent the first sealable envelope and a second portion attached to the package at a second point adjacent the second sealable envelope such that, if the first portion and the second portion of the triggering mechanism are pulled, the frangible seal is stressed to rupture, allowing the first agent to communicate with the second agent.

Description

[0001] The invention relates to self-heating / cooling packages or containers and especially a trigger mechanism therefor.[0002] Examples of flexible, chemical thermal bags are well known. Examples include U.S. Pat. No. 4,856,651 / U.S. Pat. No. 4,995,217 / CA Pat. No. 1,278,478 which describe a thermal pack including an outer pouch having a pair of opposed faces arranged generally parallel to each other and defined by a single sheet of plastic film folded along a predetermined fold line. A second sheet of plastic film is disposed between the pair of opposed faces. A continuous weld line circumscribes the periphery of the faces, with the weld line bonding together the periphery of the faces and the periphery of the second sheet to define first and second volumes within the outer pouch. The second sheet provides a common wall between the first and second volumes. A heat transfer material is disposed in the first volume and an insulating layer is disposed in the second volume, substantially...
