Trigger mechanism for self-heating/cooling packages or containers universally applied to both rigid and non-rigid packages and containers

A package comprising:

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

A package comprising:

• a first sealable envelope containing a first agent;
• a second sealable envelope containing a second agent adjacent said first sealable envelope;
• a third sealable envelope containing a third agent adjacent said second sealable envelope;
• a first frangible seal separating said first sealable envelope from said second sealable envelope;
• a second frangible seal separating said second sealable envelope from said third sealable envelope;
• a first triggering mechanism located on an exterior of said package adjacent said first frangible seal such that, if said first triggering mechanism is pulled, said first frangible seal is stressed to rupture, allowing said first agent to communicate with said second agent;
• and
• a second triggering mechanism located on an exterior of said package adjacent said second frangible seal such that, if said second triggering mechanism is pulled, said second frangible seal is stressed to rupture, allowing said second agent to communicate with said third agent.
