Abstract

A hand applicator of encapsulated liquids, such as cosmetic, hygienic, and pharmaceutical formulations or household chemicals, of different viscosity. When the user squeezes the applicator in her hand, the capsule inside it ruptures, possibly with a clap, and releases a liquid that after being collected by the drain passes through the perforated dissector to get evenly distributed in the absorber and then evenly applied on skin or other surfaces. Inert and impermeable capsules ensure stability of stored liquid formulations. Pressurized capsules are easily tactilely located and crashed. A capsule may be permanently or elastically fixed within the applicator. The applicator may include several capsules that may contain different liquids. A refillable applicator can be refilled with new capsules and used more than once. A transparent impermeable back side the applicator enhances hygiene and creates visibility of the capsule. An impervious glove-applicator for applying hazardous substances is disclosed.

Claims

1. A hand applicator of an encapsulated liquid, said applicator including a hand-breakable capsule containing a liquid and an absorber of said liquid, wherein manually squeezing said applicator causes rupture of said capsule and release of said liquid with a subsequent absorption of said liquid by said absorber, said applicator including a perforated dissector of said liquid released hereby, wherein said perforated dissector is placed within the applicator and between said capsule and said absorber, wherein said dissector has a plurality of perforations disposed opposite the entire working surface of said absorber, said plurality of perforations allow an even distribution of the released liquid from said capsule over the entire working surface of said absorber, and a drain for draining the released liquid hereby through said plurality of perforations in said perforated dissector, wherein said drain is formed by a plurality of knobs disposed between said perforated dissector and spaced between said plurality of perforations, said capsule lies on said plurality of knobs and not contacting said perforated dissector and not closing off said plurality of perforations, and wherein channels formed around said plurality of knobs allowing the released liquid from said capsule to freely flow to reach substantially all of said plurality of perforations and subsequently the entire working surface of said absorber.

2. The applicator of claim 1 wherein said drain and said dissector are made as a single element.

3. The applicator of claim 1 wherein said dissector has evenly spaced perforations.

4. The applicator of claim 1 wherein said dissector has perforations only opposite the working side of said applicator.

5. The applicator of claim 1 wherein the total area of perforations in said dissector is less than 10% of the area of said dissector.

6. The applicator of claim 1 wherein said capsule is loosely encased in said applicator.

7. The applicator of claim 1 wherein said capsule is operable to rupture when, upon squeezing hereby, the positive pressure inside said capsule reaches no less than 40 mm Hg.

8. The applicator of claim 1 wherein said capsule contains said liquid under a positive pressure of no less than 40 mm Hg.

9. The applicator of claim 1 wherein said capsule has an impermeable and inert film coating.

11. The applicator of claim 1 wherein said absorber is operable to fully absorb said liquid released from perforations in said dissector.

12. The applicator of claim 1 including a grip for holding said applicator in hand during application wherein said grip is operable to be brought in the working position only after said capsule ruptures hereby and flattens.

13. The applicator of claim 1 including a fastener for reopening said applicator to refill said applicator with a new said capsule.

14. The applicator of claim 1 wherein said capsule is permanently fixed to said dissector.

15. The applicator of claim 1 wherein said capsule is elastically fixed between said dissector and the back side of said applicator and wherein said dissector and said back side are sealed together along their edges.

16. The applicator of claim 1 including a transparent impermeable back side wherein said capsule is placed between said back side and said dissector.

17. The applicator of claim 1 being a glove that is impervious to said liquid, wherein said absorber covers the outside palmar surface of said glove and wherein said capsule is placed between said surface and said absorber.

10. The applicator of claim l wherein said capsule is partially filled with inert gas.
