DETAILED DESCRIPTION OF THE INVENTION

As indicated above, the present invention provides a flameless, portable heating container. In a typical embodiment, the heating container contains a liquid activated heating material (e.g., in pack or disk form) and utilizes a recycled heating design. The design includes a set of chambers or compartments such as: a first compartment for holding a material to be heated; a second compartment containing an activation liquid; and a third compartment comprising a protrusion and a liquid activated heating material activated by the activation liquid, the protrusion being configured to puncture a divider between the second compartment and the third compartment, so that the activation liquid contacts and activates the liquid activated heating material. It is understood that for the purposes of this disclosure, the terms chamber and compartment may be used interchangeably.
FIG. 1 shows a flameless, portable heating kit (hereinafter kit 1) according to an aspect of the present invention. As shown, kit 1 generally comprises a beverage compartment 10 having a rotation mechanism that includes a semi-helical groove 51 locking mechanism. In a typical embodiment, kit 1 includes a heating compartment 20, which will be further described in detail below.
FIG. 2 shows an exploded view of kit 1 of FIG. 1 according to an aspect of the present invention. As shown, kit 1 comprises cap 13 a, opening 13, and side wall 17 of beverage compartment 10. As further depicted, below bottom 15 of the heating compartment is an activation liquid compartment 35 that contains a liquid 33 (e.g., water) for activating liquid activated heating material 31 (e.g., in a pouch 32) to create and distribute heat within kit 1 to hat any beverage that may be contained within beverage compartment 10. Along these lines, liquid activate heating material 31 is typically positioned within heating compartment 20 along with a protrusion 40. When beverage compartment 10 and activation liquid compartment 35 are rotated (e.g., via rotation mechanism 60 of FIG. 1), protrusion will pierce a divider along the bottom of activation liquid compartment 35. This action will cause the activation liquid contained in activation liquid compartment 35 to come in contact with and activate liquid activated heating material 31, which is resting along bottom 25 of heating compartment 20 (e.g., in a ring-like manger around protrusion 40). As further shown, heating compartment 20 includes a top portion having ridges 55 for receiving beverage compartment 10 and activation liquid compartment 35 in a telescoping fashion.
FIG. 3 shows a cut-away view of kit 1 when assembled. As shown, heat compartment 10 comprises side wall 17, and inner wall 11. Typically, a beverage to be heated or kept heated will be positioned within beverage compartment 10. As further shown, activation liquid compartment 35 is positioned between beverage compartment 10 and heating compartment 20. Activation liquid compartment 35 generally comprises compartment bottom 39 on which rests a divider 39 having a puncture point 39 a. Further, activation liquid compartment 35 will contain an activation liquid 33 that will activate liquid activated heating material 31 heating compartment 20. Specifically, as indicated above, a rotation mechanism 60 of heating compartment 20 causes heating compartment 20 to be rotated with respect to beverage compartment 10 and activation liquid compartment 35. This rotation causes downward movement of beverage compartment 10 and activation liquid compartment 35 to effect the puncturing of divider 39 by protrusion 41. As a result, activation liquid 33 will contact and activate liquid activated heating material 31 and heat (or keep heated) any beverage within beverage compartment 10. In a typical embodiment, rotation mechanism 60 comprises a latch device 50 that includes a groove 51 and a peg 55. This latch device 50 will allow a user to lock heating compartment 20 so that rotation and inadvertent activation of liquid activated heating material 31 does not occur.
FIG. 4A shows a side cross-sectional view of kit 1. As depicted, a liquid (e.g., beverage) is positioned within beverage compartment 10, while activation liquid 33 is positioned within activation compartment 20. As heating compartment 20 is rotated (e.g., via groove 62 and peg 55 of latch device 50 on rotation mechanism 60, point 41 of protrusion 40 will pierce divider 39 via puncture point 39 a to cause activation liquid 33 to enter space S and activate liquid activated heating material 31 (which rests along bottom 25 of heating compartment 20).
FIG. 4B shows another side cross-sectional view of kit 1. Specifically, FIG. 4B shows the rotation of heating compartment 20 with respect to beverage compartment 10 and activation liquid compartment 35, the puncturing of divider 39 and the resulting flow of heat within kit 1.
FIGS. 5A-B show a top cross-sectional view of kit 1. As depicted, peg 55 fits within angular groove 51 to create locking mechanism 50. Specifically, peg 55 can be inserted into groove 51 as shown in FIG. 5B to prevent rotation of heating compartment 20. FIGS. 6-7 show another embodiment of locking mechanism 50. Specifically, FIG. 6 shows an angular motion of peg 55 within groove 51, while FIG. 7 shows a notch 53 implementation of locking mechanism 50.
The foregoing description of various aspects of the invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed, and, obviously, many modifications and variations are possible. Such modifications and variations that may be apparent to a person skilled in the art are intended to be included within the scope of the invention as defined by the accompanying claims.
