Abstract

A dispensing device, having a hollow nipple-shaped stopper configured to act as a one-way valve, for use as a hair dyeing comb is provided. The nipple-shaped stopper has an aperture at its tip end. The aperture opens toward outside when the operator compresses the plastic bottle and closes when the operator releases the plastic bottle. When the aperture is in its closed position, the stopper prevents the liquid hair dye already in the conduit from flowing back to the plastic bag inside the bottle. The purpose of using the stopper here is to keep the air out of the dispensing system in order for the operator to pump the liquid dye efficiently. The stopper and a small aperture at the bottom of the plastic bottle are replacing the one-way valve currently used in many hair dye-dispensing devices. With interchangeable comb heads, the operator can choose the proper comb head for his hair type and different application purpose.

Claims

1. A hair dyeing comb with interchangeable comb heads comprising:

a compressible plastic bottle having a top end and a closed bottom end wherein the top end comprises an externally threaded neck forming an opening and the bottle comprises a small aperture;

a thermal formed plastic bag encased in the plastic bottle and fitted onto the neck of the bottle, configured to retain hair dye;

a hollow nipple shaped stopper attached to the neck of the plastic bottle, where the nipple has a top end defined by a tip and an open bottom end to fluidly connect to the neck of the bottle, and a slit located on the tip;

a hollow cylindrical comb body longitudinally extending from a threaded cap toward a distal end;

the body having an open end comprising a conduit that extends the length of the comb body;

wherein the tip of the nipple shaped stopper is configured to be inserted into the conduit;

the comb body additionally comprising a row of aligned apertures that extend longitudinally along a single side of the comb body;

wherein the apertures open into the conduit;

a pair of flanged guide members that extend along both sides of the length of the comb body containing the apertures;

a transversely extending guide flange located between the row of apertures and the cap that connects ends of the guide members;

a comb head formed by a base with a recess adapted to mate with a portion of the comb body;

a row of hollow teeth;

each tooth further comprising;

a conduit that communicates with the recess and extends through the tooth to a pair of opposing apertures located a distance from a distal end of the tooth;

the apertures of adjacent teeth face each other;

the comb head further comprising a pair of longitudinally extending grooves that extend along either side of the recess to slidingly engaging the guide flanges of the comb body to allow for the comb head to attach to the comb body, such that the apertures of the comb body and the comb head align with each other;

whereby such an engagement is removable.
