Abstract
A trigger mechanism applied to rigid and non-rigid packages and containers to either heat or cool said containers. Said trigger mechanism including a non-porous flexible chamber containing an activating solution connected to another non-porous or porous, flexible chamber containing a reagent wherein previous said chamber is separated from latter said chamber by a breakable seal thus forming the heater/cooler.
Said trigger mechanism including at least one appendage, tab, string, tape, strap or ridge, attached (or otherwise integrally formed as part of the packaging) to the outer package of the heater/cooler so that when stress is applied (i.e. pulling action such as opening of a potato chip bag), there is a uniform break along the breakable seal dividing the solution chamber from the reagent chamber causing the chemicals to mix thus initiating the exothermic/endothermic reaction.
Said trigger mechanism including at least one appendage, tab, string, tape, strap or ridge, attached (or otherwise integrally formed as part of the packaging) to the outer package of the heater/cooler so that when stress is applied (i.e. pulling action such as opening of a potato chip bag), there is a uniform break along the breakable seal dividing the solution chamber from the reagent chamber causing the chemicals to mix thus initiating the exothermic/endothermic reaction.
Description
DESCRIPTION OF THE INVENTION
Said heating/cooling mechanism may include one or more flexible, rigid, porous/non-porous product container(s). Wherein the surface or part of the surface of the heater/cooler may form at least a portion of the product container/package.
In one specific embodiment, a rigid box-like container (containing the substance to be heated/cooled) may be wrapped in an outer, preferably thermally insulated sheet-like material. On at least one of the sides of the box-like container, weld-seams are formed along the perimeter of the plane. This creates an envelope space between the inner box-like container and the outer package on at least that one-side of the container.
A weaker, breakable seal is formed across the side of the box-like container dividing the envelope space into two. One chamber may contain the solvent/activating solution and the outer contains the corresponding reagent. At least one appendage, tab, string, tape, strap or ridge, attached to or forming part of the outer packaging (referred to as trigger mechanism) is incorporated so that when pulled by hand (while the other hand holds the container) the stress breaks the weaker seal pulling the outer package away from the inner, box-like container causing the chemicals to mix initiating the reaction.
Another specific embodiment of said invention contains all of the elements described above with the exception that instead of an inner box-like product container, there is a flexible pouch-like product container/package. There are at least 2 trigger mechanisms. One located on the same side as the heating/cooling elements, the other trigger mechanism on the opposing side of the container, such that when both or pulled, the entire package flexes to it's maximum at which point, the stress breaks the seal dividing the heating/cooling elements thus triggering the reaction.
As previously stated, the triggering mechanism may be in the form of an appendage, tab, string, tape, strap or ridge, or any similar form as long as it is attached to or integrated as part of the outside of the exterior packaging and enable the user to grasp on so as to provide pulling resistance. Said trigger mechanism may be rigid or flexible.
Said trigger mechanism may be incorporated into any portions) of the exterior packaging, but preferably close to or traversing breakable seal in order to apply maximum stress to the breakable seal vicinity.
One embodiment includes a package having one or more products/product containers/product pouches with one or more heating/cooling elements wherein said product containers/packages may be rigid or flexible. Each heating/cooling element may have its own triggering mechanism or trigger mechanisms. Heating/Cooling chambers may be formed at least in part from a flexible or rigid packaging material.
Said chambers may be independent or at least in part be formed from the product packaging/container which in turn may be at least in part from either or both flexible or rigid material.
This type of packaging and triggering mechanism will prove highly useful when one is transporting volatile, hazardous, unstable, reactive or explosive compounds of chemicals, or chemicals with a pre-determined life or length of use. Said chemicals or compounds can be separated into the two chambers in non-reactive, non-volatile, non-hazardous, non-explosive states. When the chemical is needed, the chemicals can be mixed by triggering the triggering mechanism and causing the chemicals to mix, react and produce the final product chemical needed for the particular application.
For rigid packages an adhesive tape can be wound around flexible outer package thereby pinching part of outer package against inner rigid packaging creating two envelope spaces between outer flexible package and inner rigid package to form another type of trigger mechanism. One envelope above, the other below the adhesive tape such that when tape is unwound, the two envelopes join allowing chemicals to mix, thereby initiating the reaction.
