Abstract

A disposable fluid applicator having a reservoir with a first membrane and a second membrane. Said reservoir containing a fluid to be dispensed. Said first membrane of the reservoir having perforations and being covered by a permeable and/or absorbent spreader. A removable tab assembly is disposed between said spreader and said first membrane of the reservoir that seals said perforations. When the tab is pulled from between said spreader and said first membrane of the reservoir the perforations are unsealed allowing the fluid contained inside the reservoir to flow out through the perforations into and through the spreader where the fluid can be applied to a desired surface.

Claims

1. A disposable fluid applicator consisting of a tab assembly, an applicator assembly and a reservoir assembly;

Said reservoir assembly having a reservoir formed by a first membrane and a second membrane sealed together around the periphery of said first membrane and said second membrane;

Said reservoir containing a fluid to be dispensed;

Said first membrane having a central zone having a plurality of perforations;

Said second membrane being impermeable;

Said applicator assembly being porous and being affixed to said first membrane around a periphery of said applicator assembly;

Said applicator assembly covering said perforations;

Said tab assembly being disposed between said first membrane and said applicator assembly;

Said tab assembly sealing said perforations in said first membrane;

Said tab assembly being removable from between said first membrane and said applicator assembly, fully separating from the fluid applicator, thereby unsealing said perforations and allowing said fluid to dispense into and through said applicator assembly.

2. A disposable fluid applicator as described in claim 1 further characterized in that a seal is affixed to said first membrane that is adhearable to said applicator assembly when said tab assembly is removed that substantially completes a seal between the periphery of said first membrane and the periphery of said applicator assembly.

3. A disposable fluid applicator as described in claim 1 further characterized in that said applicator assembly is formed of any one of a non-woven fibrous material, a fabric material, a sponge material or a porous synthetic material.

4. A disposable fluid applicator consisting of a tab assembly, an applicator assembly and a reservoir assembly;

Said reservoir assembly having a reservoir formed by a first membrane and a second membrane sealed together around the periphery of said first membrane and said second membrane;

Said reservoir containing a fluid to be dispensed;

Said first membrane having a central zone having a plurality of perforations;

Said second membrane being impermeable;

Said applicator assembly being absorbent and being affixed to said first membrane around a periphery of said applicator assembly;

Said applicator assembly covering said perforations;

Said tab assembly being disposed between said first membrane and said applicator assembly;

Said tab assembly sealing said perforations in said first membrane;

Said tab assembly being removable from between said first membrane and said applicator assembly, fully separating from the fluid applicator, thereby unsealing said perforations and allowing said fluid to dispense into and through said applicator assembly.

5. A disposable fluid applicator as described in claim 4 further characterized in that a seal is affixed to said first membrane that is adhearable to said applicator assembly when said tab assembly is removed that substantially completes a seal between the periphery of said first membrane and the periphery of said applicator assembly.

6. A disposable fluid applicator as described in claim 4 further characterized in that said applicator assembly is formed of any one of a non-woven fibrous material, a fabric material, a sponge material or a porous synthetic material.

7. A disposable fluid applicator comprising a tab assembly, an applicator assembly and a reservoir assembly;

Said reservoir assembly having a reservoir formed by a first membrane and a second membrane sealed together around the periphery of said first membrane and said second membrane;

Said reservoir containing a fluid to be dispensed;

Said first membrane having a central zone having a plurality of perforations;

Said second membrane being impermeable;

Said applicator assembly being porous and being affixed to said first membrane around a periphery of said applicator assembly;

Said applicator is substantially equal in size to the reservoir;

Said applicator assembly covering said perforations;

Said tab assembly being disposed between said first membrane and said applicator assembly;

Said tab assembly sealing said perforations in said first membrane;

Said tab assembly being removable from between said first membrane and said applicator assembly, fully separating from the fluid applicator, thereby unsealing said perforations and allowing said fluid to dispense into and through said applicator assembly;

a seal is affixed to said first membrane that is adhearable to said applicator assembly when said tab assembly is removed that substantially completes a seal between the periphery of said first membrane and the periphery of said applicator assembly.

8. A disposable fluid applicator as described in claim 7 further characterized in that said applicator assembly is formed of any one of a non-woven fibrous material, a fabric material, a sponge material or a porous synthetic material.

9. A disposable fluid applicator comprising a tab assembly, an applicator assembly and a reservoir assembly;

Said reservoir assembly having a reservoir formed by a first membrane and a second membrane sealed together around the periphery of said first membrane and said second membrane;

Said reservoir containing a fluid to be dispensed;

Said first membrane having a central zone having a plurality of perforations;

Said second membrane being impermeable;

Said applicator assembly being absorbent and being affixed to said first membrane around a periphery of said applicator assembly;

Said applicator assembly covering said perforations;

Said applicator is substantially equal in size to the reservoir;

Said tab assembly being disposed between said first membrane and said applicator assembly;

Said tab assembly sealing said perforations in said first membrane;

Said tab assembly being removable from between said first membrane and said applicator assembly, fully separating from the fluid applicator, thereby unsealing said perforations and allowing said fluid to dispense into and through said applicator assembly;

a seal is affixed to said first membrane that is adhearable to said applicator assembly when said tab assembly is removed that substantially completes a seal between the periphery of said first membrane and the periphery of said applicator assembly.

10. A disposable fluid applicator as described in claim 9 further characterized in that said applicator assembly is formed of any one of a non-woven fibrous material, a fabric material, a sponge material or a porous synthetic material.
