Abstract
Radial pressure exerted against a deflectable sidewall of an outer container initiates a chemical reaction in which the temperature of a product in an inner cup is changed.
Description
- 1. Field of the Invention
- The present invention generally relates to an arrangement that adds or removes heat from a product, such as a food, beverage, medicine, or like product and, more particularly, to promoting user acceptance of the arrangement by enhancing its operation.
- 2. Description of the Related Art
- Self-heating or self-cooling arrangements are known in which a product, typically a beverage, is heated or cooled by employing two chemical reactants which are stable when separated, but which produce an exothermic or an endothermic reaction when mixed. U.S. Pat. No. 4,793,323 shows one example of a single-use, self-heating container for liquids or solids, in which a breakable membrane keeps the reactants apart, and a breakable member is actuated by a user to break the membrane and allow the reactants to mix to form the chemical reaction that changes the temperature of the product.
- As advantageous as the known self-heating containers are, experience has shown that the actuation by the user is difficult for at least some users to perform. More specifically, the user is expected to axially depress an actuator button provided on the bottom of the container. Even if the user is prompted as to the location of the actuator button, the user is required to invert the container, and then exert a significant amount of physical force to depress the button along the axis of the container for the axial distance required to break the membrane and initiate the self-heating action. Some users, particularly the elderly and children, do not have the strength to activate the self-heating action.
- Accordingly, it is a general object of this invention to promote user acceptance, and to enhance the operation, of arrangements that add or remove heat from a product.
- More particularly, it is an object of the present invention to reduce the amount of physical force required to activate the temperature-changing action.
- Still another object of the present invention is to provide a reliable arrangement for, and method of, selectably changing the temperature of a product.
- In keeping with the above objects and others which will become apparent hereinafter, one feature of the present invention resides, briefly stated, in an arrangement for, and a method of, changing a temperature of a product, typically a food or a beverage, comprising an outer container, preferably made of a thermally insulating material, having a side wall bounding an interior and spaced radially from an axis, and an inner cup, preferably made of a thermally conductive material, fixedly mounted within the interior of the container and having a chamber for containing the product. Preferably, the cup and the container have juxtaposed flanges fused together by spin-welding.
- A breakable membrane, for example a circular, thin foil, is fixedly mounted within, and subdivides, the interior of the container into a pair of compartments. The container is formed with an internal annular shoulder, and a circular periphery of the membrane is adhered to the shoulder. A pair of reactants is respectively contained in the compartments, and the reactants are kept apart by the membrane prior to use. For example, the reactants may be water and anhydrous calcium oxide or calcium chloride which, when mixed, produce an exothermic chemical reaction.
- A breaking member is mounted within the interior of the container in a juxtaposed relationship with the membrane. The breaking member is at least partially supported by the internal shoulder of the container. In accordance with this invention, a radial pressure is exerted by the user on the side wall of the container, and this radial pressure causes the breaking member to break the membrane and allow the reactants to mix and produce the chemical reaction that changes the temperature of the product in the cup.
- In contrast to the known art, the temperature changing action is not initiated by inverting the container to expose an actuator button on the bottom of the container. Nor is the temperature change actuated by axially depressing a button with a significant amount of force. Instead, the upright container is radially constricted by squeezing the side wall adjacent the shoulder between opposed fingers. The user need only hold the container in one's palm and close his or her fingers around the side wall in the action of making a fist. This fist-making movement is much easier for the user to perform as compared to the depression of a button.
- The novel features which are considered as characteristic of the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.

FIG. 8 is a top plan view of a partially removed seal on a product cup for use in the arrangement ofFIG. 1 ; and -
FIG. 9 is a top plan view of a sip lid for use in the arrangement ofFIG. 1 . - As best shown in
FIGS. 1-2 , an arrangement in accordance with this invention includes anouter container 10 having aside wall 12 bounding an interior, aninner cup 14 fixedly mounted within the interior of thecontainer 10, abreakable membrane 16 fixedly mounted within the interior of thecontainer 10 and subdividing the interior into a pair ofcompartments reactants compartments membrane 16 prior to use, and a breakingmember 26 mounted within thecontainer 10, preferably above themembrane 16, and operative for breaking themembrane 16, as described below, to allow thereactants cup 14. Aseal 28 seals the product within thecup 14. An aperturedsip lid 30 is optionally mounted over theseal 28 and over thecontainer 10. - The
container 10 is symmetrical about anupright axis 32, and theside wall 12 circumferentially surrounds theaxis 32. Theside wall 12 is preferably frusto-conical or cylindrical. Thecontainer 10 is formed with an interiorannular shoulder 34 on which a circular periphery of themembrane 26 is adhesively secured. A circular periphery of the breakingmember 26 also rests on theshoulder 34. Thecompartment 18 above themembrane 16 is filled with one of thereactants 22, for example, water, and thecompartment 20 below themembrane 16 is filled with the other of thereactants 24, for example, anhydrous calcium oxide or calcium chloride. Other reactants are contemplated by this invention, and the positions of the reactants could be reversed, that is, the water could be in the lower compartment, while the anhydrous calcium oxide or calcium chloride could be in the upper compartment. Thecontainer 10 is preferably constituted of a thermally insulating material, for example, a thermoformed foamed polypropylene, and theside wall 12 is deformable radially inwardly, as described in detail below. - The
inner cup 14 contains the product and can consist of a thermoformed plastic or is preferably constituted of a thermally conductive material, for example, a polyethylene coating over an aluminum core formed by a deep draw stamping process. The product can be virtually anything, but is preferably a beverage, such as coffee or tea, or a soup, or a foodstuff. Theseal 28 seals the product within the cup. Theseal 28, as best shown inFIGS. 4 and 8 , includes anannular rim 36 mechanically crimped over a radialannular flange 38 of thecup 14, and adiaphragm 40 adhesively mounted on therim 36 and peelably removable from therim 36 by pulling on apull tab 42. The rim, diaphragm and pull tab are preferably constituted of aluminum which is stamped and die cut into their illustrated shapes. Theseal 28 hermetically seals the product before and during the temperature change. Once the temperature change has been achieved, the pull tab is pulled to at least partially remove the diaphragm and gain access to the product. - The
membrane 16 is a thin, tearable foil die cut into a circular shape and preferably constituted of aluminum. An adhesive at its periphery adheres the membrane to theshoulder 34 and is preferably thermally activated. - The breaking
member 26, as best seen inFIGS. 6-7 , is an injected molded polypropylene plastic operative to pierce and tear themembrane 16. The breakingmember 26 has a plurality ofradial arms barb 54 that lies along theaxis 32 and faces themembrane 16. A plurality ofabutments side wall 12 against which the abutments contact (seeFIG. 5 ). - As shown in
FIG. 2 , themembrane 16 is intact, and the breakingmember 26 rests on themembrane 16 and theshoulder 34. If a radial pressure is exerted on theside wall 12 adjacent theshoulder 34, as schematically illustrated by the opposingfingers 66 of a user's hand moving in the directions ofarrows 68, then theside wall 12 deforms inwardly, the abutments are pushed inwardly, the living hinges 64 bend, the arms are pushed downwardly, the living hinges 52 bend, and the pointedbarb 54 moves downwardly and pierces themembrane 16. Thereactant 22 in theupper compartment 18 flows downwardly through the ruptured membrane and chemically reacts with thereactant 24 in thelower compartment 20. - To promote the speed and efficiency of the chemical reaction, the user can shake the arrangement, typically for about 10-20 seconds, and can even invert the arrangement and allow it to stand, typically for less than two minutes. In the preferred embodiment, about 28 grams of a granulated calcium chloride (grain size 1-2 mm) are used. The liquid reactant need not be pure water, but can be mixed with an acid, such as oxalic acid. In about one minute's time, the temperature of the exothermic reaction caused when water and calcium chloride interact rises from a room temperature of about 19° C. to a temperature of about 60° C., which is sufficient to heat the product within the cup.
- The radial pressure is exerted between the opposing
fingers 66. As shown, there are four zones, one corresponding to eachabutment side wall 12. Otherwise, it is sufficient for the user to merely hold the container in his or her hand and grip tightly as if making a fist. This radial squeezing is continued until resistance is felt when theside wall 12 engages thecup 14. This cup thus serves as a safety stop for preventing the user from completely crushing the arrangement. A label can be applied on the side wall which not only provides sales and marketing information, but also prominently displays the finger pressure zones. - Once the recommended waiting period has elapsed, the arrangement is returned to its original upright position, and the
pull tab 42 is pulled back to either partially or completely remove thediaphragm 40 depending upon the type of product in the cup and how it will be consumed. For example, a spoon requires more room to access soup within the cup as compared to a beverage which is directly sipped. If the product is a beverage, such as coffee, then thesip lid 30 is snapped over the opened seal, and the beverage is consumed through an aperture 70 (seeFIG. 9 ). - It will be understood that each of the elements described above, or two or more together, also may find a useful application in other types of constructions differing from the types described above.
- While the invention has been illustrated and described as embodied in a arrangement for and method of selectably changing the temperature of a product, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.
- Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.

12. The method of claim 11 , wherein the sealing step is performed by mechanically crimping an annular rim of a seal over a flange of the cup.
13. The method of claim 11 , wherein the fixedly mounting step is performed by spin-welding the cup inside the container.
14. The method of claim 11 , wherein the subdividing step is performed by adhering a periphery of the membrane to an internal shoulder of the container.
15. The method of claim 11 , wherein the exerting step is performed by radially constricting the side wall of the container in a user's hand.
16. A method of consuming a product whose temperature has been changed, comprising the steps of:
a) at least partly filling a cup with the product;
b) sealing the product within the cup;
c) fixedly mounting the sealed, product-filled cup inside a container having a side wall surrounding, and spaced from, an axis;
d) subdividing an interior of the container into a pair of compartments by mounting a breakable membrane within the container;
e) at least partly filling a pair of reactants respectively into the compartments;
f) mounting a breaking member within the interior of the container;
g) exerting a radial pressure on the side wall of the container and causing the breaking membrane to break the membrane to allow the reactants to mix and form a chemical reaction that changes the temperature of the product in the cup;
h) unsealing the cup; and
i) consuming the product within the unsealed cup.
17. The method of claim 16 , wherein the unsealing step is performed by at least partly peeling a diaphragm off a seal sealed to the cup.
18. The method of claim 17 , and the step of mounting an apertured lid on the unsealed cup, and wherein the consuming step is performed by consuming the product through the apertured lid.
19. A breaking member, comprising:
a) a pointed barb movable along an axis;
b) a plurality of abutments spaced apart circumferentially of the axis; and
c) a plurality of arms extending radially outwardly in different directions from the barb, the arms having inner ends hingedly connected to the barb, and outer ends hingedly connected to the abutments.
20. The breaking member of claim 19 , wherein the abutments are curved and lie along an annulus surrounding the axis.
