Abstract
Abstract A fabric garment which automatically removes unwanted hair while being worn against the skin of the user. The garment is coated with a pressure sensitive microencapsulated depilatory agent. Pressure exerted by a hair stubble against the fabric causes the microencapsulation to rupture and dispense the depilatory agent in a small localized area around the hair follicle. The depilatory agent dissolves the hair stubble without irritating the user's skin.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
61 words
A garment wearable by a person to automatically remove unwanted hair, comprising: fabric coated with plural microcapsules; a liquid depilatory agent contained within said plural microcapsules; and said microcapsules comprising a pressure-sensitive thin shell which releases said depilatory agent in response to pressure exerted by a hair stubble, said depilatory reducing the disulfur cross-links of said hair stubble upon contact therewith.
Claim 2
Dependent Claim
61 words
A garment wearable by a person to automatically remove unwanted hair, comprising: fabric coated with plural microcapsules; a liquid depilatory agent contained within said plural microcapsules; and said microcapsules comprising a pressure-sensitive thin shell which releases said depilatory agent in response to pressure exerted by a hair stubble, said depilatory reducing the disulfur cross-links of said hair stubble upon contact therewith.
Claim 3
Dependent Claim
18 words
The garment of claim 1 wherein said thin shell selectively releases said depilatory agent at said hair stubble.
Claim 4
Dependent Claim
21 words
The garment of claim 1 wherein said depilatory agent chemically removes said hair stubble without irritating the skin of the user.
Claim 5
Dependent Claim
17 words
The garment of claim 1 wherein said depilatory agent is inert with respect to said thin shell.
Claim 6
Independent Claim
66 words
A device for removing hair stubble from legs comprising: a stocking worn against the skin of a user; minute, easily frangible capsulation means on the fabric of said stocking, said means being rupturable by the pressure of said hair stubble thereagainst; and a liquid depilatory contained within said capsulation means, said depilatory being released upon rupture of said capsulation means to chemically remove said hair stubble.
Claim 7
Independent Claim
66 words
A device for removing hair stubble from legs comprising: a stocking worn against the skin of a user; minute, easily frangible capsulation means on the fabric of said stocking, said means being rupturable by the pressure of said hair stubble thereagainst; and a liquid depilatory contained within said capsulation means, said depilatory being released upon rupture of said capsulation means to chemically remove said hair stubble.
Claim 8
Dependent Claim
12 words
The device of claim 5 wherein said stocking comprises a snug-fitting hosiery.
Claim 9
Dependent Claim
15 words
The device of claim 5 wherein said depilatory agent comprises a non-skin irritating liquid solution.
Claim 10
Dependent Claim
16 words
The device of claim 5 wherein said depilatory is inert with respect to said capsulation means.
Claim 11
Independent Claim
57 words
A device for automatically removing hair from legs comprising: a hosiery worn tightly against the skin of a user; and a dispersion of pressure-sensitive depilatory capsules carried by said hosiery, said capsules rupturing and releasing a fluid depilatory agent in a localized area surrounding a hair stubble upon pressure exerted by said hair stubble against said capsules.
Claim 12
Independent Claim
57 words
A device for automatically removing hair from legs comprising: a hosiery worn tightly against the skin of a user; and a dispersion of pressure-sensitive depilatory capsules carried by said hosiery, said capsules rupturing and releasing a fluid depilatory agent in a localized area surrounding a hair stubble upon pressure exerted by said hair stubble against said capsules.
Claim 13
Dependent Claim
37 words
The process of coating hosiery with a liquid depilatory agent comprising the steps of: encapsulating said liquid depilatory agent in easily frangible, hard shelled microcapsules; and depositing a large plurality of said microcapsules upon surfaces of hosiery.
Claim 14
Dependent Claim
37 words
The process of coating hosiery with a liquid depilatory agent comprising the steps of: encapsulating said liquid depilatory agent in easily frangible, hard shelled microcapsules; and depositing a large plurality of said microcapsules upon surfaces of hosiery.
Claim 15
Dependent Claim
81 words
The process of removing body hair comprising the steps of: microencapsulating a liquid depilatory agent in plural, thin-walled, pressure-sensitive shells; depositing said microencapsulated depilatory agent upon a flexible substrate; contacting said substrate against the hair stubbled skin of a user; and rupturing said thin shell by pressure exerted by a hair stubble on said shell to selectively release said liquid depilatory agent in a localized area surrounding said hair stubble, said depilatory agent chemically removing said hair stubble upon contact therewith.
Claim 16
Dependent Claim
81 words
The process of removing body hair comprising the steps of: microencapsulating a liquid depilatory agent in plural, thin-walled, pressure-sensitive shells; depositing said microencapsulated depilatory agent upon a flexible substrate; contacting said substrate against the hair stubbled skin of a user; and rupturing said thin shell by pressure exerted by a hair stubble on said shell to selectively release said liquid depilatory agent in a localized area surrounding said hair stubble, said depilatory agent chemically removing said hair stubble upon contact therewith.
Claim 17
Independent Claim
60 words
A device to remove body hair comprising: a flexible material coated with plural microcapsules; and liquid depilatory agent contained within said plural microcapsules, said microcapsules comprising a micro-thin shell which selectively releases said depilatory agent for contacting a hair stubble in response to pressure exerted by said hair stubble when said flexible material tightly contacts the skin of a user.
Claim 18
Independent Claim
60 words
A device to remove body hair comprising: a flexible material coated with plural microcapsules; and liquid depilatory agent contained within said plural microcapsules, said microcapsules comprising a micro-thin shell which selectively releases said depilatory agent for contacting a hair stubble in response to pressure exerted by said hair stubble when said flexible material tightly contacts the skin of a user.
Claim 19
Independent Claim
73 words
A device for automatically removing body hair comprising: a flexible material having a depilatory agent contained thereon; and means responsive to the presence of a hair stubble extending above said body for automatically dispensing said depilatory agent in a localized area at said hair stubble when said flexible material is held against said body of a user to remove said hair stubble while limiting the application of said agent to said body itself.
Claim 20
Independent Claim
73 words
A device for automatically removing body hair comprising: a flexible material having a depilatory agent contained thereon; and means responsive to the presence of a hair stubble extending above said body for automatically dispensing said depilatory agent in a localized area at said hair stubble when said flexible material is held against said body of a user to remove said hair stubble while limiting the application of said agent to said body itself.
Claim 21
Dependent Claim
41 words
The device of claim 13 wherein said means for dispensing said depilatory agent comprises a plurality of microcapsules storing said depilatory agent and having pressure-sensitive thin shells which release said depilatory agent in response to pressure exerted by said hair stubble.
