DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a finger protector configured for placement on at least two fingers (‘mitten’). The mitten is useful to prevent fingers from burning. For example, a mitten of the present invention is optionally used while braiding synthetic hair in its molten state. When synthetic hair is braided, the ends are melted (e.g. with an open flame) and matted together to prevent unraveling.

Accordingly, the present invention now provides a mitten comprising insulation and a shell of a flame-resistant, non-stick material. With both insulation and a non-stick surface, such a mitten now enables hairstylists to manipulate synthetic hair in its molten state.

Specifically, one embodiment provides a mitten comprising at least one finger holder, an insulation layer, and a shell layer, wherein:

• • a. the insulation layer is positioned between the shell layer and the at least one finger holder;
  • b. the at least finger holder is configured for placement over the back side of at least one finger; and
  • c. the shell layer comprises a flame-resistant, non-stick material, wherein said non-stick is with respect to synthetic hair in its molten state.

Finger Holder

A mitten of the present invention comprises at least one finger holder. The finger holder can be any component configured for holding the other layers (insulation and shell) to the finger.

Optionally, the at least one finger holder is configured as a sheath.

Optionally, the at least one finger holder comprises an elastic material.

Optionally, the at least one finger holder comprises a plurality of finger holders. Optionally, the at least one finger holder comprises 2, 3, 4, or 5 finger holders. Optionally, the finger holder is configured for placement on the thumb and a second finger (e.g. index or middle finger).

Optionally, the finger holder does not cover a majority of the back of a hand, i.e. it is substantially an open-back mitten.

Optionally, the finger holder is configured for placement over the finger tip, a majority of the finger, or the entire finger.

Optionally, the finger holder is any finger holder described by U.S. Pat. No. 4,751,747.

The mitten can comprise finger holders that cover a portion of the finger, e.g. at least the first digital of top of a finger and/or thumb (e.g. the distal phalange portion).

Insulation

A mitten of the present invention comprises at least one layer of insulation positioned between the finger holder and the shell. The insulation layer can be any layer that provides thermal insulation, e.g. to prevent burning of the finger when manipulating molten synthetic hair and/or introducing an open flame.

Optionally, the insulation layer comprises wool. Other useful insulation materials include polyester, cotton or rayon

The insulation can be used as a buffer between the heat and finger therefore the thickness of the insulation is a major component of the functionality and practicality of the item, once flame is extinguished.

Optionally, the insulation layer provides cushion or padding (e.g. a wool layer).

Optionally, the insulation layer is any insulation layer described by U.S. Pat. No. 4,751,747.

Optionally, the insulation layer has a thickness equal to or less than any of: ¼ in, ⅛ in, 1/16 in. Optionally, the insulation layer has a thickness equal to or greater than 1/32 in.

Shell

A mitten of the present invention comprises a shell layer. The shell layer can be any flexible layer that is flame-resistant and non-stick. As used herein, the term “non-stick” refers to the ability of the shell layer to freely move about synthetic hair in its molten state.

Optionally, the shell layer is configured as any flexible material, e.g. a woven or non-woven fabric.

Optionally, the shell layer comprises an organic material (e.g. organic polymers), a non-organic material (e.g. silica), or a combination thereof.

Optionally, the shell layer comprises an organic polymer. The organic polymer can be any that is or can be configured or modified to provide a flame-resistant, non-stick material. Examples of useful organic polymers include polytetrafluoroethylene (PTFE), which is commonly used in non-stick materials.

Optionally, the shell layer comprises a silicate or silicon dioxide. Optionally, the shell layer comprises amorphous silica fabric (e.g. AVSiI Silica Fabrics).

Optionally, the shell layer comprises a composite of an organic polymer and a non-organic material, e.g. a PTFE/fiberglass composite (e.g. EJ™ 1650)

The skilled artisan will appreciate that, while certain materials such as wool are generally flame-retardant, they do not provide a non-stick surface (unless modified). With the teachings provided herein, however, the skilled artisan can now readily configure shell layers that are flame-retardant and non-stick with respect to molten synthetic hair.

Fibers such as wool, nylon, rayon, cotton or any other synthetic fiber could not be used exclusively for the shell because melted synthetic hair would stick to or adhere to it.

Optionally, the shell layer has a thickness equal to or less than any of: ⅛ in, 1/16, 1/32, or 1/64 in. Optionally, the shell layer has a thickness equal to or greater than 1/90 in.

Methods

A mitten of the present invention can be used, e.g. to protect the fingers while manipulating molten hair.

In one embodiment, the invention also provides a method of protecting a finger comprising:

• • a. wearing any mitten of the invention on one or more fingers;
  • b. applying an open flame to synthetic hair, thereby melting the synthetic hair; and
  • c. manipulating the melted hair using the one or more fingers.

Optionally, the method further comprises a step of braiding the synthetic hair before said step of applying an open flame.

Optionally, the step of manipulating comprise matting the molten synthetic hair.

Optionally, hair is cut to uniform length then burned, then matted to shape ends with finger protector.

EXAMPLES

Example 1

Mitten

FIGS. 1a-1c depict an example mitten of the invention. The mitten comprises a finger holder 1, an insulation layer 2, and shell layer 3. The finger holder 1 comprises first finger holder 4 and a second finger holder 5.

The finger holder 1 comprises an elastic material configured to stretch over the fingers of a user.

The insulation layer 2 comprises a layer of wool with a thickness of about 1/16 inch.

The shell layer 3 comprises a layer of flame resistant, non-stick material. For example, the shell layer can comprise an amorphous silica fabric (e.g. AVSiI Silica Fabrics) or a PTFE/fiberglass composite fabric (e.g. EJ™ 1650).

The shell layer 3 and insulation layer 2 are held together in any manner (e.g. sewn or glued). Each of the finger holders 4, 5 are secured to the insulation layer 2 and/or shell layer 3 only at their perimeter on three sides, thereby providing a sheath with an opening to accept a finger.

The insulation layers and shell layer are optionally configured as thin as possible to accord ample dexterity to hairstylist while manipulating molten synthetic hair. For example, a layer of wool insulation can optionally be about 1/16 inch. A layer of PTFE/fiberglass composite fabric (e.g. EJ™ 1650) can optionally be about 1/64 inch an inch and a layer of an amorphous silica fabric (e.g. AVSiI Silica Fabrics) can optionally be about 1/32 inch.
