Abstract
Abstract An applicator for dispensing and spreading hair remover adhesive such as beeswax includes a variable size chamber in which solid or semi-solid hair remover adhesive can be selectively heated to optimum extrudable conditions. The mass flow rate at which ribbons of hair remover adhesive is extruded onto a hair growth area, can be regulated by adjusting the biasing force exerted on a spring loaded piston. Application of the adhesive proceeds neatly and quickly.

Claim 1
Independent Claim
320 words
An applicator for dispensing and spreading hair remover adhesive onto a hair growth area, comprising: a. a container having an upper portion formed with a dispensing neck and a lower portion that is generally open and formed with internal threads; b. a piston slidably positioned within the container and arranged for movement along the longitudinal axis of the container; c. a variable chamber formed by the container and the piston; d. a supply of hair remover adhesive in the variable chamber; e. a plunger with external threads inter-engaged with the internal threads of the container lower portion, so the plunger may be selectively advanced towards the container upper portion or retracted; f. biasing means interposed between and engaging both the piston and the plunger so that pressure exerted on the piston by the biasing means may be selectively increased or decreased as the plunger is advanced and retracted respectively; g. heating means in the container upper portion adjacent the variable chamber in order to melt the hair remover adhesive, the heating means including an electrical wire wound substantially throughout a segment of the container upper portion to fully surround a segment of the variable chamber, and, a switch connected to the electrical wire so heating may be selectively initiated and terminateD; h. a dispensing head removably coupled to the dispensing neck for dispensing and spreading melted hair remover adhesive onto a hair growth area when melted hair remover adhesive is extruded through the dispensing head under pressure from the piston and/or gravitational force; i. an outermost part of the dispensing neck offset and inclined away from the axis of the container; and j. a handle connected to a side of the container and having a grasping bar arranged in a manner so that when held substantially horizontal it serves to maintain the dispensing neck outermost part in a substantially erect position for best dispensing and spreading melted hair remover adhesive.

Claim 3
Dependent Claim
24 words
The structure according to claim 1 wherein: the biasing means is a coiled spring extending approximately between the centers of the plunger and piston.
Claim 4
Dependent Claim
39 words
The structure according to claim 2 wherein: the inner face of the plunger is attached to the coiled spring and the outer face of the plunger is formed with a hand grip to facilitate advancing and retracting the plunger.
Claim 5
Dependent Claim
36 words
The structure according to claim 1 including: a removable cap secured within an opening in the container upper portion, through which new pieces or charges of hair remover adhesive may be deposited into the variable chamber.
Claim 6
Dependent Claim
23 words
The structure according to claim 1 wherein; the dispensing neck bears threads to removably hold one of multiple and selectively interchangeable dispensing heads.
