Abstract

Compositions and methods for deterring and/or visually identifying oral contact with objects that are hazardous upon oral contact or ingestion are disclosed. The compositions generally comprise a colorant and a carrier and may further comprise an aversive agent, a salivating agent, and/or an emetic. The compositions may be particularly useful for application to batteries, including button cells.

First claim

I claim:

1. A battery comprising:
a battery having an external surface or a component, the external surface or the component having at least a portion that is exposed to moisture upon immersion of the battery; and
a composition comprising:
an aversive agent;
a releasable colorant; and
a salivating agent,

wherein the composition is coated onto the external surface or is incorporated into the component wherein the specific electrical resistance and overall viscosity of the composition are higher than 1.0×10 3 Ω•m and 2.0×10 −5 Pa•s, respectively, at 20° C.

2. The battery of claim 1 , wherein the composition further comprises a carrier.

3. The battery of claim 2 , wherein the carrier comprises a monosaccharide, a disaccharide, a polysaccharide, or mixtures thereof.

4. The battery of claim 1 , wherein the aversive agent comprises a chemical selected from group consisting of ammonium benzoate, denatonium benzoate, denatonium saccharide, denatonium chloride, sucrose octaacetate, 2,3-dimethoxystrychnine, quassinoids, flavonoids, including quercetin, absinthin, resinferatoxin, capsaicin, nonivamide, piperine, allyl isothiocyanate and mixtures thereof.

5. The battery of claim 1 , wherein the releasable colorant is selected from the group consisting of FD&C Red 40; Red 3; D&C Black 3; Black 2; Mica-based pearlescent pigment; FD&C Yellow 6; Green 3; Blue 1; Blue 2; titanium dioxide; and mixtures thereof.

6. The battery of claim 1 , wherein the salivating agent comprises a chemical selected from the group consisting of adipic acid, ascorbic acid, citric acid, fumaric acid, lacticacid, malic acid, tartaric acid, alkyl aryl sulfonates, alkyl sulfates, sulfonated amides, sulfonated amines, sulfated esters, sulfonated esters sulfated ethers, sulfonated ethers, alkyl sulfonates, polyethoxlyated esters, monoglycerides, diglycerides, diacetyl tartaric esters of monoglycerides, polyglycerol esters, sorbitan esters, ethoxylates, lactylated esters, phospholipids, polyoxyethylene sorbitan esters, proplyene glycol esters, sucrose esters, and mixtures thereof.

7. The battery of claim 1 , wherein the composition as further comprises an emetic.

8. The battery of claim 7 , wherein the emetic comprises a chemical selected from the group consisting of syrup of ipecac, 10-chloro-5,10-dihydroarsacridine, 10-chloro-5,10-dihydrophenarsazine, 5-aza-10-arsenaanthracene chloride, diphenylaminechlorarsine, diphenylaminearsine chloride, diphenylcyanarsine, phenyldichloroarsine, and mixtures thereof.

9. The battery of claim 1 , wherein the battery is a button cell.

10. The battery of claim 9 , wherein the component is an insulation of the button cell.

11. A method of visually identifying oral contact with a battery, comprising:
coating an external surface of a battery with a composition or incorporating the composition into a component of the battery, the external surface or the component having at least a portion that is exposed to moisture upon immersion of the battery, the composition comprising:
an aversive agent;
a releasable colorant; and
a salivating agent; and

releasing the colorant upon contacting of the composition with an oral area to stain the oral area wherein the specific electrical resistance and overall viscosity of the composition are higher than 1.0×10 3 Ω•m and 2.0×10 −5 Pa•s, respectively, at 20° C.

12. The method of claim 11 , wherein the battery is a button cell.

13. The method of claim 11 , further comprising correlating the color of the stained oral area with an external reference to identify the battery.

14. A method of preventing ingestion of a battery that is hazardous upon ingestion, comprising:
coating an external surface of a battery with a composition or incorporating the composition into a component of the battery, the external surface or the component having at least a portion that is exposed to moisture upon immersion of the battery, the composition comprising:
an aversive agent;
a releasable colorant; and
a salivating agent; and

releasing the aversive agent upon contacting of the composition with an oral area to impart an offensive flavor and/or odor to the oral area wherein the specific electrical resistance and overall viscosity of the composition are higher than 1.0×10 3 Ω•m and 2.0×10 −5 Pa•s, respectively, at 20° C.

15. The method of claim 14 , wherein the battery is a button cell.

16. The method of claim 14 , further comprising removing the battery from oral area.
