## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority to and the benefit of U.S. Provisional Patent Application Ser. No. 60/892,504, entitled “Exothermic Condom Packaging”, to Mallory et al., filed on Mar. 1, 2007, and the specification thereof is incorporated herein by reference.


BACKGROUND OF THE INVENTION
1. Field of the Invention (Technical Field)
Embodiments of the present invention relate to exothermic condom packaging which releases heat through an exothermic chemical reaction of reactants that are preferably non-toxic and which most preferably comprise an aqueous solution, thus heating a condom contained in the packaging.
2. Description of Related Art
While condoms and their packaging have been known for some time, the known condoms and packaging that produce a warming sensation rely on sensation-producing chemicals, such as menthol, and thus do not produce a true warming effect. There is thus a need for a condom package which can quickly and effectively heat a condom prior to use thus providing a true warming effect.
BRIEF SUMMARY OF THE INVENTION
One embodiment of the present invention is a condom package comprising a plurality of chambers, a first reactant disposed in a first chamber, a second reactant disposed in a second chamber, at least one breachable seal between the chambers with the reactants and a condom disposed in one of the chambers. The reactants are reactable to produce an exothermic reaction when in contact after the seal is breached. The package can have the condom in contact with at least one of the reactants prior to breaching the seal. Alternatively, the condom does not have contact with the reactants prior to breaching the seal. In addition, the condom does not have to have contact with the reactants even after the seal is breached. If the condom does not have contact with the reactants after the seal is broken then the condom is preferably heated by thermal conduction through one or more walls of the plurality of chambers from the exothermic reaction of the reactants after the reactants are in contact with each other. The package can further comprise a flavoring agent and/or a lubricant disposed within at least one of the chambers.
Another embodiment of the present invention is a method for using an exothermic condom package. This method provides a package having a plurality of chambers, a first reactant disposed in the first chamber, a second reactant disposed in the second chamber, at least one breachable seal and a condom disposed in one of the chambers. Then at least one of the seals is breached which contacts and reacts the reactants with each other causing an exothermic reaction and generating heat. The condom is then heated from the exothermic reaction and the condom is then removed from the packaging for use. The method can have the condom contacting at least one of the reactants prior to breaching the seal. The method can optionally prevent the condom from having contact with the reactants prior to breaching the seal. Finally, the method can prevent the condom from having contact with the reactants after breaching the seal. If the condom does not have contact with the reactants after breaching the seal, the condom is heated by thermal conduction through one or more walls of the plurality of chambers after reacting the reactants and generating heat. The method can also have a flavoring agent and/or a lubricant in at least one of the chambers.
A further embodiment of the present invention is a method for heating a condom comprising mixing a plurality of reactants to produce an exothermic reaction, generating heat from the reaction and heating the condom. This method can additionally comprise storing the reactants and the condom within a package and optionally comprise contacting the reactants with one another at a time just prior to using the condom. The time can be less than about 10 minutes prior to using the condom. The reactants can be separated from the condom so there is no contact between the reactants and the condom, or at least one of the reactants can have contact with the condom.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention relates to a condom package which heats a condom and contains a warming personal lubricant contained therein. Preferably, the condom is heated by an exothermic reaction which is most preferably initiated by a user breaking or breaching an inner seal that separates the reactants.
The term “reactant(s)”, as used throughout the specification and claims, includes one or more chemicals or components which can be combined with one or more other chemicals or components to produce an exothermic reaction.
As illustrated in the embodiment of FIG. 1, assembly 10 preferably comprises condom 12, which is preferably in a rolled or otherwise flattened condition, and package 14. Package 14 preferably comprises first chamber 16 and second chamber 18. Chambers 16 and 18 are preferably separated by seal 20. In the embodiment of FIG. 1, condom 12 is preferably contained within first chamber 16. First reactant 22 is preferably disposed within first chamber 16 of package 14, and second reactant 24 is preferably disposed within second chamber 18 of package 14. The packaging in FIG. 1 is substantially flat.
As illustrated in the embodiment of FIG. 2, assembly 110 preferably comprises condom 112, which is preferably in a rolled or otherwise flattened condition, and package 114. Package 114 preferably comprises first chamber 116 and second chamber 118. Chambers 116 and 118 are preferably separated by seal 120. In the embodiment of FIG. 2, condom 112 is preferably contained within first chamber 116. First reactant 122 is preferably disposed within first chamber 116 of package 114, and second reactant 124 is preferably disposed within second chamber 118 of package 114. The packaging in FIG. 2 is substantially three-dimensional.
While numerous materials are known to those skilled in the art for providing packaging, the packaging preferably comprises a waterproof material and is preferably a plastic material, although any materials useful for containing a condom and reactants may be used in accordance with the invention. The seal is preferably the barrier formed between first and second chambers. The seal is most preferably formed by thermally fusing an upper-portion of the packaging to a lower-portion thereof. Although, adhesively bonding upper and lower-portions of the packaging can also provide desirable results, as well as other manners of providing the seal as known in the art.
One more lubricants and/or flavoring agents can also optionally be included within first chamber 216 and/or second chamber 218. Although second chamber 218 is most preferably an extension of first chamber 216, second chamber 218 can optionally comprise a second container or chamber disposed within first chamber 216 (see FIG. 3). In this embodiment, seal 220 thus comprises an outer portion or edge of second chamber 218.
In using the embodiments of the present invention illustrated in FIGS. 1-3, a user preferably squeezes the first and/or second chambers or otherwise causes the seal to be breached, thus enabling the first reactant to be mixed with the second reactant, which thus heats the condom. After the condom is heated to a desired temperature, the user preferably cuts or otherwise tears open the packaging and removes the condom therefrom. In these embodiments, the condom is in contact with at least one reactant before the seal is breached.
While various manners of providing seals are known to those skilled in the art, the seals are preferably provided by attaching an upper-portion of the packaging to a lower-portion thereof, and most preferably by thermally fusing an upper-portion of the packaging to a lower-portion thereof. However, desirable results can also be obtained by adhesively adhering the upper-portion to the lower portion thereof.
In one embodiment, one or more lubricants and/or a flavoring agent can be disposed in one or more chambers. Although some of the embodiments of the present invention show first and second chambers comprising or containing reactants, other embodiments of the present invention can optionally provide multiple other chambers which can themselves optionally hold one or more other reactants or additives.
FIG. 4 illustrates an embodiment of the present invention wherein assembly 50 preferably comprises first chamber 52, second chamber 54 and third chamber 56 of packaging 58. Condom 60 is preferably, but optionally, disposed within third chamber 56 of packaging 58. A lubricant and/or flavoring agent 62 are also preferably disposed within third chamber 56. Third chamber 56 is preferably formed with a thermally conductive material such as foil, although other materials including but not limited to plastic, can produce desirable results as well. First chamber 52 of packaging 58 preferably houses first reactant 64. Second chamber 54 of packaging 58 preferably houses second reactant 66. Seal 68 preferably separates packaging 58 into first chamber 52 and second chamber 54. Seal 68 is preferably provided by attaching an upper-portion of packaging 58 to a lower-portion thereof, and most preferably by thermally fusing an upper-portion of packaging 58 to a lower-portion thereof. Of course, adhesively attaching upper and lower-portions of packaging 58 can also produce desirable results. Seal 70 is preferably attached near a terminal portion of packaging 58, such that condom 60 can be removed from third chamber 56. Seal 70 preferably comprises a tear-away or otherwise breakable seal, and is most preferably provided by thermally fusing an upper-portion of packaging 58 to a lower portion thereof. One or more perforations can optionally be disposed through or near seal 70 for ease in tearing or opening.
To use the embodiment illustrated in FIG. 4, a user preferably squeezes first chamber 52 and/or second chamber 54, or otherwise causes seal 68 to be breached, enabling first reactant 64 to mix with second reactant 66, thus resulting in an exothermic reaction which heats optional lubricant and/or flavoring agent 62 and condom 60 by thermal conduction through one or more walls of third chamber 56 and thereby heating condom 60 without direct contact to any of the reactants. After condom 60 is heated to a desired temperature, the user preferably tears or otherwise cuts open packaging 58 near or at seal 70 and removes condom 60 from packaging 58. As illustrated in FIG. 4, the condom does not have contact with the reactants even after the seals are breached.
FIGS. 5A-C illustrate another embodiment of the present invention. As shown therein, assembly 80 preferably comprises condom 82 which is preferably rolled or otherwise flattened and disposed with chamber 84 of assembly 80. Optionally, lubricant 94, is also disposed near condom 82 in chamber 84. Lid 85 covers a top of chamber 84. Lid preferably comprises a pull tab 87. A reactant, preferably a powder reactant 86, is disposed in another chamber 88. Another reactant, preferably a liquid reactant 90, is disposed within another separate chamber 92. Chamber 88 is preferably disposed between top cover 94 and bottom cover 96. Chamber 88 is disposed near or partially within chamber 86 and these chambers 88 and 86 are sealed from each other, initially. Disposed in top cover 94 is an area or indentation 98 which is pressed by the user.
To use the embodiment illustrated in FIGS. 5A-C, the user presses on press area 98, which causes chamber 92 to compress and burst. Reactant or liquid 90 flows or reacts with reactant 86 in chamber 88 to create an exothermic reaction. When condom 82 is sufficiently heated, the user pulls on pull tab 87, lifting lid 85, to withdrawn condom 82 for use. In this embodiment, condom 82 is not in contact with reactants 86 and 90.
One embodiment of the present invention comprises contacting the reactants with one another at a time just prior to using the condom. Another embodiment of the present invention comprises contacting the reactants with one another at a time of less than about 10 minutes prior to using the condom. A further embodiment of the present invention comprises not contacting the condom with the reactants at all and using thermal conduction to heat the condom.
Reactants useful in the present invention include but are not limited to the components described herein. Lubricants useful in the present invention include but are not limited to the components described herein. Flavoring agents useful in the present invention include but are not limited to synthetic or natural flavor blends available in the food and flavor industry, and includes the components described herein. A detailed discussion of reactants, lubricants and flavoring agents is discussed below.
Reactants
The exothermic reaction in this invention does not involve or require water from the human tissue as in other lubricants. Instead, the invention releases a controlled amount of water during the reaction. Thus, it is rendered safer then other warming products since neither the epidermis nor the mucosa acts as a partner or a vessel for the reaction. The liquid product of the reaction is warm, preferably approximately 5 to 30 degrees Fahrenheit above ambient temperature, and retains and gently radiates such temperature for about 5 to 25 minutes from the time of application. It is also formulated to the pH environment of healthy living tissue, such as the skin, the vaginal cavity or other mucosa, and is a mild, non-irritant on healthy normal skin and/or mucosa.
The structure of the media in which the warming reaction occurs is selected to accommodate and safely deliver a wide variety of natural and/or synthetic extracts and drugs known to help soothe some epidermal and vaginal symptoms, including but not limited to, dysmenorrhea.
The preferred reactants are compatible with spermicides including, but not limited to, certain Nonoxynol compounds and others such as methoxypolyoxyethyleneglycol 550 laurate.
The heat and warming effects of the reactants come from an acid-base (redox) exothermic reaction. The selection of an acid and/or a base depends on suitability and ability to instantly produce the desired heat as well as the nature of final reaction products and the safety impacts on the living tissue. Several preferred reactants are described below.
There are at least two reactants, described as Part A and Part B. Part A includes, but is not limited to, the reaction matrix as described above, plus the designated components (including but not limited to acid or combinations of acids) as selected for the heating reaction. Such acid(s) preferably include but are not limited to carboxylic, of the type mono-, di- or poly-carboxylic functional group(s) such as acetic, propionic, salicylic, valeric, vanillic, lactic, sorbic, glyceric, hippuric, benzoic, gluconic, malic, tartaric, glutaric, citric, and the like, but may also be of the amino carboxylic type, such as amino acetic acid (glycine), 2-amino glutaramic acid (glutamine), glutamic acid, folic acid, and the like. The monosodium salt of L-glutamic acid may also be used in the heat generating reaction due to its active carboxylic group. A suitable non-carboxylic acid, including but not limited to kojic acid or the like may be applied to Part A to enter the reaction as an acidulant or as a part of a buffer system.
Part B includes a reactant (preferably a base) that is completely or partially soluble in water, alcohol, ether and/or a mixture with or without the addition of one of the above mentioned polyols used herein as a thickener, solubilizer and/or aid for the heat transferring rate. The base reactant may include, but is not limited to, a hydroxide of one of the alkaline earth metal members of Ia and IIa of the periodic table, and/or the like reactants, preferably and including but not limited to potassium, sodium, magnesium, iron or calcium. Ammonium hydroxide (aqua ammonia) and/or ammonium bicarbonate and/or sodium carbonate or bicarbonate are preferable as they have been found to deliver the desired temperature using the proper molar ratio against the selected acid. The oxide salts of magnesium, calcium and sodium also were found to generate appreciable heat. Part B, in its composition, may or may not include certain amounts of viscosity builder, heat insulator, tissue rejuvenator, soothing agent and/or the dye as suitable. However, and in all cases, while selecting the proper reagents located in two separate reacting bodies, Parts A and B, they preferably exhibit one or more of the following attributes:
