Abstract
Abstract A one piece fluid applying device is formed of flexible material that is folded to form a chamber to contain a fluid. The flexible material is impermeable and unaffected by the fluid. A seal is formed about the chamber to maintain the fluid tight integrity thereof. Surface portions of the flexible material which form walls of the chamber also form surfaces for applying the fluid to another surface, for example, to the skin of a patient.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
172 words
A combined fluid storage container and applicator device for relatively inviscid fluids such as alcohols and iodine, said device comprising a single integral sheet of fluid impermeable material folded in generally symmetrical halves over on itself along a fold line positioning said halves in flat parallel overlying relation to each other, temporary seal means sealing said halves to each other along a temporary seal line beginning and ending at said fold line forming a cavity enclosing fluid between said halves and within said temporary seal line and said fold line, a fluid comprising at least one of alcohol and iodine in said cavity, and separation means for simultaneously applying separating force substantially symmetrically to both said halves of said sheet and to said temporary seal means without tearing said sheet, said separation means including means for applying simultaneously continuous separating force to open said temporary seal means along the entire length of said seal line to form a flat surface covered with the fluid while the integrity of said sheet is maintained.
Claim 2
Dependent Claim
172 words
A combined fluid storage container and applicator device for relatively inviscid fluids such as alcohols and iodine, said device comprising a single integral sheet of fluid impermeable material folded in generally symmetrical halves over on itself along a fold line positioning said halves in flat parallel overlying relation to each other, temporary seal means sealing said halves to each other along a temporary seal line beginning and ending at said fold line forming a cavity enclosing fluid between said halves and within said temporary seal line and said fold line, a fluid comprising at least one of alcohol and iodine in said cavity, and separation means for simultaneously applying separating force substantially symmetrically to both said halves of said sheet and to said temporary seal means without tearing said sheet, said separation means including means for applying simultaneously continuous separating force to open said temporary seal means along the entire length of said seal line to form a flat surface covered with the fluid while the integrity of said sheet is maintained.
Claim 3
Dependent Claim
33 words
A device as set forth in claim 1 wherein said seal line is spaced inward from the periphery of said sheet of material to provide manually engageable perimeter portions outside said seal line.
Claim 4
Dependent Claim
62 words
A device as set forth in claim 1 wherein the fluid is medicinal and at least a portion of the surface of said material enclosed by said fold line and said seal line includes textured surface means for both retaining fluid and abrading a surface to which the fluid is to be applied thereby to promote the therapeutic effect of the fluid.
Claim 5
Dependent Claim
38 words
A device as set forth in claim 3 wherein the fluid is sterile and said seal line is spaced inward from the periphery of said sheet of material to provide manually engageable perimeter portions outside said seal line.
Claim 6
Dependent Claim
9 words
The device of claim 1, said material comprising foil.
Claim 7
Dependent Claim
13 words
The device of claim 5, said material further comprising an inner plastic liner.
Claim 8
Dependent Claim
9 words
The device of claim 1, said material comprising paraffin.
Claim 9
Dependent Claim
9 words
The device of claim 1, said material comprising wax.
Claim 10
Dependent Claim
9 words
The device of claim 1, said material comprising plastic.
Claim 11
Dependent Claim
24 words
The device of claim 1, said flexible material being of oval shape when open and semi-oval shape when folded closed to enclose the fluid.
Claim 12
Dependent Claim
21 words
The device of claim 1, wherein said seal line is at least approximately parallel to a perimeter of the folded material.
Claim 13
Dependent Claim
18 words
The device of claim 1, wherein said flexible material is diamond shaped when open and triangular when folded.
Claim 14
Dependent Claim
29 words
The device of claim 1, wherein the wall surfaces of said material that are exposed to said fluid have relatively high surface energy for facilitating containment of said fluid.
Claim 15
Dependent Claim
30 words
The device of claim 1, wherein the wall surfaces of said material means that are exposed to said fluid and forms said chamber do not covalently bond with said fluid.
Claim 16
Dependent Claim
20 words
The device of claim 1, wherein said material is sealed along said seal line by applying heat to said material.
Claim 17
Dependent Claim
14 words
The device of claim 15, said material comprising foil having an inner plastic liner.
Claim 18
Dependent Claim
20 words
The device of claim 1, wherein said material is sealed along said seal line by applying pressure to said material.
