Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
142 words
A molding kit comprising a substantially cylindrical, elongate container open at one end and closed at its other end, a quantity of heat-liquifiable molding material housed within said container, and a closure member securely, though releasably, secured to the free open end of the container for enclosing the contents thereof, said closure member having peripheral side walls which project outwardly from and completely circumscribe a central portion having indicia embossed therein, said container fabricated from material adapted to withstand the application of heat sufficient to liquify the molding material in the container, said closure member when removed from the container and inverted defining a mold adapted to receive and contain the heat-liquified molding material from the container for providing a mirror-image of the indicia of the mold, which image is reproduced in said material as it cools and hardens in the mold.
Claim 2
Dependent Claim
142 words
A molding kit comprising a substantially cylindrical, elongate container open at one end and closed at its other end, a quantity of heat-liquifiable molding material housed within said container, and a closure member securely, though releasably, secured to the free open end of the container for enclosing the contents thereof, said closure member having peripheral side walls which project outwardly from and completely circumscribe a central portion having indicia embossed therein, said container fabricated from material adapted to withstand the application of heat sufficient to liquify the molding material in the container, said closure member when removed from the container and inverted defining a mold adapted to receive and contain the heat-liquified molding material from the container for providing a mirror-image of the indicia of the mold, which image is reproduced in said material as it cools and hardens in the mold.
Claim 3
Dependent Claim
48 words
A molding kit as called for in claim 1, wherein the heat-liquifiable molding material comprises a soap having a melting point sufficiently low to preclude inflicting a burn if accidentally spilled onto the bare skin of a person, and which upon cooling hardens to permit handling without distortion.
Claim 4
Dependent Claim
20 words
A kit as called for in claim 2, wherein the soap has a melting point in the neighborhood of 120*-130*F.
Claim 5
Dependent Claim
38 words
A kit as called for in claim 1, wherein the container is fabricated from material adapted to withstand prolonged and repeated immersion in a liquid bath of a temperature sufficient to liquify the molding material in the container.
Claim 6
Dependent Claim
86 words
A kit as called for in claim 1, wherein a second closed member, having peripheral side walls which project outwardly from and completely circumscribe a central portion having indicia embossed therein, is removably secured to and carried by the closed end of the container, said closure member defining a mold adapted to receive and contain the heat-liquified contents from the container for providing a mirror-image of the indicia of the mold, which image is reproduced in said material as it cools and hardens in the mold.
Claim 7
Dependent Claim
54 words
A kit as called for in claim 1, wherein a plurality of individual molds, each having peripheral side walls which project outwardly from and completely circumscribe a central portion having indicia embossed therein, are provided in nested relationship, and wherein the bottommost mold is releasably secured to and carried by the said closure member.
Claim 8
Dependent Claim
56 words
A kit as called for in claim 1, wherein one or more individual molds, each of which have peripheral side walls which project outwardly from and completely circumscribe a central portion having indicia embossed therein, are provided interiorly of the container between the upper surface of the molding material housed therein and the said closure member.
Claim 9
Dependent Claim
42 words
A kit as called for in claim 1, wherein the closure member is adapted to be securely, though releasably, resecured to the free open end of the container for enclosing the molding material remaining therein after a molding operation has been completed.
