BACKGROUND OF THE INVENTION Field of the Invention (Technical Fields

[0003] Embodiments of the present invention relate to warming or cooling body foam or cream and a temperature safety system for a warming body solution.

Description of Related Art:

[0004] There are many warming products on the market that warm the skin or mucosa as they are applied, for example, a personal warming lubricant. The degree of warming may vary depending on the chemical nature and composition of the product. When these products are applied, the temperature of the surrounding environment is unpredictable and not under control. The present invention can be added to the composition of these products to control the warming temperature as they are applied to the skin or mucosa.

[0005] There are many types of warming and/or cooling foams or creams known in the art.

These warming and/or cooling foams or creams typically generate heat or cooling through the application of one-phase systems seeking water to generate heat or cooling. These foams or creams depend on the existence of water in or around living tissue to initiate an exothermic or exothermic reaction to generate the desired heat. In other words, the known art uses a technique that may render living tissue as a reaction vessel while generating heat or cooling. Thus, a minimum degree of moisture must exist in or around living tissue to initiate the warming or cooling sensation of known warming or cooling foams or creams.

[0006] Other warming and cooling foams or cream fail to control the range of heat or cooling produced since their warming and cooling sensation depends on the molar amount of water existing in or around the tissue at the time of application. Further, the known warming and cooling foams or creams have some risk of human error in the applicative technique whereas the present invention prevents risk of human error in its applicative technique.

[0007] While known foams or creams heat or cool by using inner tissue moisture or surrounding water, the present invention releases water in a warm or cool environment and utilizes two separate phases that react instantly together to produce the foam or cream desired as well as the heat or cooling needed. The present invention generates the desired heat or cooling using reagents in a manner independent of the existence of water in the surrounding environment, and administers it safely to living tissue. In other words, the present invention does not depend on any amount of moisture to exist in the living tissue to initiate any of the reactions desired. Therefore, the present invention is very helpful for cases of severe dryness because it restores the vitality of the dry tissue.

[0008] There are many warming products on the market that warm the skin or mucosa as they are applied, for example, a personal warming lubricant. The degree of warming may vary depending on the chemical nature and composition of the product. When these products are applied, the temperature of the surrounding environment is unpredictable and not under control. Embodiments of the present invention can be added to the composition of these products to control the warming temperature as they are applied to the skin or mucosa.

[0009] In contrast to known warming and cooling foams or creams, the present invention demonstrates full control over the amount of heat or cooling produced. Therefore, it is very suitable for temperature sensitive reactants, as well as other reactants with optimum temperature to operate.

[0025] As used herein, "a" means one or more.

[0026] As used herein, "microsphere", "nanosphere", "bead" or "capsule" means a small unit of matter that can be symmetric (including but not limited to a sphere), asymmetric (including but not limited to a dumbbell), or a macromolecule having symmetry or no symmetry.

[0027] The term "foam" as used herein is intended to include foams, creams, lubricants, or other similar solutions.

[0028] As used herein, "solution" means a foam, a liquid, a gel or any other solution that can be applied to a body.

WARMING OR COOLING BODY FOAM

[0029] An embodiment of the present invention is preferably a non-toxic gentle warming or cooling body foam or cream that is formed by a moderate endothermic or exothermic chemical reaction.

[0030] In an embodiment of the present invention, the foam is used during intimate encounters, as a shaving foam or cream, or is used as a non-irritating skin soother. The solution may be edible. The foam may provide a slight cooling or warming sensation that is pleasant to the touch and easy to rinse off. The chemical reactants which form the foam are preferably introduced in one part or can alternatively be presented in separate parts. For example, in one embodiment of the present invention, the reaction starts as soon as a gentle rubbing of the reactants is conducted by the user. In a second embodiment of the present invention, the reaction starts when at least two reactants are mixed and rubbed against each other. In both embodiments, the foam may provide its own source of water so water from the skin or mucosa is not required to be a trigger media reagent for the reaction. [0031] An embodiment of the present invention is further enhanced with one or more edible flavors available in the market, including but not limited to edible fatty acids, fruit extracts and or natural oil flavor such as orange, coconut oil, strawberry, blueberry, cherry, raspberry, chocolate, an combinations thereof.

[0032] In a preferred embodiment of the present invention and as illustrated in Fig. 1 , the foam is dispensed from a nozzle dispenser, wherein the reactants are stored separately and blend immediately before or upon application to skin or mucosa. Multiple component bags or a single component bag or any similar suitable design may also be used to dispense the foam. The pH of the foam is adjusted to be compatible with and suitable for the skin and mucosa (generally between a pH of 5.5 to 7.5). Thus, preferably the pH of the foam ranges from approximately 4 to 7, and most preferably between 5 to 6.5. The foam is preferably non-toxic and safe to use. The foam may be easy to swallow without any chewing efforts or mechanical complications especially for users who may have trouble swallowing while lying flat or horizontally.

[0033] Referring to Fig. 1 , an embodiment of the present invention comprises packaging for a non-toxic gentle warming or cooling body foam or cream that is formed by a moderate endothermic or exothermic chemical reaction. This embodiment preferably comprises single nozzle dispenser 100, where reactants 102 and 104 blend immediately before or upon application to skin or mucosa. In this embodiment, reactants 102 and 104 are preferably stored separately. When a user depresses nozzle 106, reactants 102 and 104 are pushed up to nozzle 106, mixed, and released through nozzle 106 via a mechanical action or the release of a compressed gas.

[0034] In another embodiment, the foam composition creates a good matrix for many vitamins and minerals; hence vitamins and minerals can be easily added to the foam to nourish the skin as well as the body when the foam is ingested.

[0035] In yet another embodiment, the reactants may be mixed within a product package where the reactants are separated by seals and are mixed when the seals are broken. Additionally, the reactants may be encapsulated for a triggered release reaction in a single phase. In each case, the delivery dispensing system is slightly different to accommodate and fulfill a user friendly and easy application. Thus, embodiments of the present invention are designed to provide safe, pleasant, joyful experience to users such as patients or playful partners.

[0036] One embodiment of the present invention comprises a foam that is non-sticky, non- greasy and non-irritating, with a pleasant odor. This embodiment also preferably enhances and is compatible with most human pheromones. The foam is suitable for use of users of all ages and body conditions. The product presentation and simple application technique is versatile. For example, the foam can be used as a lubricant when inserting a relatively stiff object during the delivery of medical treatment or washing reagents in areas hard to reach such as the rectum and the vaginal cavity or may be handy when using a play toy.

[0037] Another embodiment of the present invention comprises a foam that is substantially hydrous. The foam of this embodiment preferably comprises water ranging from between approximately 50% to 98% by weight, more preferably between approximately 50% to 90% by weight, and most preferably between approximately 87% to 95% by weight. While other products seek water from living tissue, the foam of this embodiment releases a controlled amount of water that is slightly cool or warm. The human mucosa and/or skin are not required to be a reaction vessel or even participate by any means for the release of water for the cool or warm sensation. Since water from human mucosa or skin is not required to warm or cool the body foam, there is no risk of loosing the vital water that is in living tissue. Instead, the invention generously introduces water and lubricates, In fact, the foam can easily support an antibiotic or germ inhibitor, thus, it can be a vehicle for antibiotic or germ inhibition treatment.

[0038] Further, because embodiments of the present invention are water miscible, the foam is easily rinsed using any of the available vinegar-based over the counter reagents, including but not limited to, Summer's Eve™ douche or similar products. While the chemical components of other available products may provide no control over temperature level, embodiments of the present invention can control temperature level by simply controlling the amount of moles of the reacting reagents causing the heating or cooling effect. Furthermore, and in contrary to other products, the chemical composition of embodiments of the invention, as well as the delivery system, prevent human error when used by having a formula composition allowing a wide range for error.

[0047] In a one-part embodiment of the present invention, at least two reactants, an acid and a base, preferably one of the reactants or reagents mentioned above for cooling or heating sensations, are encapsulated in hydrophobic micro spheres, beads or capsules (preferably clear and virtually invisible) that are slightly larger than the nano range of less than 0.1 micron. The size of the micro spheres preferably range from approximately 0.1 to 50 microns. More preferably, DermaSal™ nano spheres (manufactured by Salvona) or a similar brand are used for localizing the delivery of an active ingredient onto a target site. Upon friction, when rubbing or mixing the portion in use, the capsules release the reactants to instantly generate the warm or cool body foam. Each individual capsule may contain the proper ratio of reactants calculated as needed and known to the public of chemistry.

Citric acid and/or sodium bicarbonate or sodium hydroxide are preferably encapsulated together in the dry water free form.

TEMPERATURE CONTROL SYSTEM

[0048] An embodiment of the present invention comprises a temperature control system to control the warming of body foams, creams or lubricants.

[0049] One embodiment of the present invention utilizes macro, micro, and/or nano technologies individually or combined to suppress any undesired increase in the final temperature of the product due to the uncontrolled and possibly high temperature of the environment where the product might be applied.

[0050] Another embodiment of the present invention uses a suitable insulating agent known for its heat capacity and ability to absorb heat. The insulating agents preferably have high molecular densities, for example, polyethylene glycol. Other insulating agents can include, but are not limited to, honey or similar function compounds, such as the mono-, di- and poly-sacharides. Other examples include, but are not limited to glucose, fructose, sucrose, sorbitol, sorbose, amylum, pectin, xanthan gum and/or derivatives and/or the trichlorogalactosucrose (TGS) known as sucralose, a member of the polyol family, corn starch, and/or derivatives or chemically similar ingredients. Sole compound and/or articulate mixtures of the above can also be used. A nonionic, water soluble ether of cellulose and ethylene oxide is also preferably part of the matrix mixture, such as the hydroxyethylcellulose series known as natrosols and/or derivatives and the like compounds. The main function of such insulating agents is to absorb the excess heat when generated. The insulating agents are released when the temperature exceeds a certain limit and hence, suppress any undesired increase in the final temperature of the product. The insulating agents are preferably inert to the product environment, are preferably released when the temperature exceeds a designated limit, have heat capacity suitable to perform as needed, and are safe when released into the environment. In addition, the insulating agents preferably do not change the integrity of the chemical composition of the product such as the product's lubricity, pH value, and/or flavor. Further, the insulting agents are non-irritating to the skin and mucosa, non-toxic and non-carcinogenic.

[0051] One or more insulating agents are preferably encapsulated in a hydrophobic microsphere including but not limited to a Microsal™ capsule (manufactured by Salvona) to form a safety capsule. The delivery of the insulating agents is preferably localized onto a target site. The capsule material is preferably transparent or virtually invisible or may be matched to the product's general profile. The size of a capsule may vary from approximately 0.1 micron up to 300 microns. The size of a capsule is preferably approximately 50 to 150 microns. Gel capsulation is also suitable for encapsulating insulating agents. The gel capsule wall thickness varies according to the maximum heat desired. The wall thickness may vary from approximately 500 to 5000 microns as needed. In a preferred embodiment, the gel capsule is triggered by moisturized heat and not moisture by itself.

[0052] The safety capsules encapsulating the insulating agent or agents may be located in any part of a product. For example, if one product has two parts, A and B, and these parts react together to form a final product, the insulating agent can be added to either the A part, the B part or both. Thus, when part A is mixed with part B, the heat releasing reaction starts and the product temperature rises to the designated maximum temperature as mentioned above. If the environment temperature before initiating the reaction is preferably in the range of approximately 100⁰F to 110⁰F, the total end temperature of the product plus the environment may exceed approximately 130° F. When the temperature or pressure reaches above what is desirable (e.g. a temperature of 100° F to 13O⁰F), the encapsulated particles are released and suppress any temperature increase using the heat capacity feature. If the temperature or pressure does not exceed the limit, the release of the insulating agent does not occur. The amount of temperature safety capsules in the product preferably ranges from between approximately 5% to 50% by weight of the total composition, more preferably ranges from between approximately 5% to 25% by weight, and most preferably ranges from between approximately 15% to 25% by weight. The larger the size of the capsules, the fewer number of capsules per gram weight are required to suppress the heat. The entire amount of insulating agent released, however, is preferably proportional to the amount of suppressed heat.

[0053] Although the invention has been described in detail with particular reference to these preferred embodiments, other embodiments can achieve the same results. Variations and modifications of the present invention will be obvious to those skilled in the art and it is intended to cover in the appended claims all such modifications and equivalents. The entire disclosures of all references, applications, patents, and publications cited above are hereby incorporated by reference.
