Abstract
Abstract An integral alcohol preparation device (10) or like type of fluid applying device includes an absorbent material or pad (11) for containing alcohol or other fluid, a fluid impermeable material, for example of metal foil (20) lined with plastic (21), as a selectively openable fluid tight chamber for the pad and fluid contained therein, and the pad and fluid impermeable material being attached as a substantially integral assembly. Being so attached, a method of using such a fluid applying device, then, may include the steps of manipulating the fluid impermeable material to open the chamber and to expose the pad and fluid contained therein without breaching the integrity of the several parts individually or collectively, and applying the fluid from the pad to an external surface. Further, a method is disclosed for making an integral fluid applying device. In an alternate embodiment 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. Similar methods of use and manufacturing may be employed with both embodiments. In both embodiments the flexible fluid impermeable material may be a single piece or may be comprised of plural pieces fastened together, e.g., along an edge of the device, and intended to remain so fastened during use.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
209 words
A combined fluid storage container and applicator device for relatively inviscid fluids, said device comprising a sheet-like fluid impermeable material having generally symmetrical halves positioned in generally flat parallel overlying relation to each other, a pair of respective edges of said material halves being securely joined along an effective fold line as an effectively single integral sheet of said material halves, temporary seal means sealing said halves to each other along a temporary seal line beginning and ending at said fold line forming a cavity and enclosing fluid between said halves and within said temporary seal line and said fold line, a fluid 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 in at least two opposing directions continuous separating force out of the plane and at an angle that is no greater than about a perpendicular to the generally planar extent of the device to open said temporary seal means along at least a portion of the 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
209 words
A combined fluid storage container and applicator device for relatively inviscid fluids, said device comprising a sheet-like fluid impermeable material having generally symmetrical halves positioned in generally flat parallel overlying relation to each other, a pair of respective edges of said material halves being securely joined along an effective fold line as an effectively single integral sheet of said material halves, temporary seal means sealing said halves to each other along a temporary seal line beginning and ending at said fold line forming a cavity and enclosing fluid between said halves and within said temporary seal line and said fold line, a fluid 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 in at least two opposing directions continuous separating force out of the plane and at an angle that is no greater than about a perpendicular to the generally planar extent of the device to open said temporary seal means along at least a portion of the 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
The device of claim 1, wherein said material halves are originally separate pieces of sheet material, and said secure joining thereof at said fold line comprises a secure fastened junction of said pieces.
Claim 4
Dependent Claim
20 words
The device of claim 1, further comprising a fluid retaining pad disposed in said cavity and adhered to said material.
Claim 5
Dependent Claim
20 words
A device of claim 3, wherein the peripheral border of said pad are spaced inwardly of said temporary seal line.
Claim 6
Dependent Claim
47 words
The device of claim 3, said fluid retaining pad covers approximately one-half the surface of said material enclosed by said temporary seal line when said material is unfolded whereby the other half of said material enclosed by said temporary seal line comprises a cover for said cavity.
Claim 7
Dependent Claim
31 words
A device of claim 1, wherein said temporary seal line comprises the inner border of a temporary seal zone and is spaced inward from the periphery of said sheet of metal.
Claim 8
Dependent Claim
53 words
The device of claim 1, wherein said separation means includes means for facilitating applying force to said temporary seal means to breach the same and to open said chamber for access to the fluid therein, said means for facilitating comprising protruding opposite unsealed portions of said halves of said sheet of impermeable material.
Claim 9
Dependent Claim
48 words
A device of claim 1, wherein said temporary seal line is spaced inward from the periphery of said sheet of material to define between said periphery and said temporary seal line a seal zone as a manually graspable perimeter portion of the device outside said temporary seal line.
Claim 10
Dependent Claim
40 words
The device of claim 1, said fold line comprising a peripheral seal line at the borders of two equally flat halves of said material and along which a continuation of simultaneous separating forces separates such two halves of said material.
Claim 11
Dependent Claim
28 words
The device of claim 1, further comprising handle means for facilitating manual grasping of the device for use, said handle means comprising a crimp in said impermeable material.
Claim 12
Dependent Claim

The device of claim 10, said handle means comprising approximately a 90° reverse fold in said sheet of impermeable material out of the major plane of said sheet material.
Claim 13
Dependent Claim
19 words
The device of claim 1, wherein the fluid is sterile and comprises at least one of alcohol and iodine.
Claim 14
Dependent Claim
