Abstract

Abstract A mold assembly for use in making molded toy objects such as figurines and the like has at least two main mold sections and a plurality of interchangeable mold elements adapted to be respectively removably mounted in at least one of the main mold sections. The two main mold sections and the interchangeable mold elements have cooperating mold cavities therein which define the toy object to be molded in the assembly. One of the main mold sections has a recessed receptacle portion in which at least one of the interchangeable mold elements can be selectively positioned. These interchangeable mold elements are each formed to define the body portion of a different figurine or toy object so that a variety of objects can be formed with the two main mold sections by simply interchanging the mold elements placed in the receptacle portion of the one main mold section.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 300 words
A mold assembly for use in making molded toy figurines from a settable liquid mold material, said assembly comprising a pair of mold halves and a plurality of interchangeable mold elements adapted to be respectively removably mounted in one of said mold halves, said mold halves and said interchangeable mold elements having cooperating mold cavities of distinct configuration defining a toy figurine mold when said mold halves are placed in juxtaposition with said cavities facing each other; the cavity of said one mold half including an integrally formed first cavity portion corresponding to a portion of the configuration of the figurine to be formed and a second cavity portion for removably and interchangeably receiving at least one of said mold elements therein, whereby a portion of the configuration of the side of the figurine formed by said one mold half may be varied by selectively interchanging the mold elements received in said second cavity portion; said second cavity portion being dimensioned to receive at least two of said interchangeable mold elements and said interchangeable mold elements defining at least two groups of mold elements, corresponding respectively to at least two body portions of the figurines to be formed, with each mold cavity in said elements having a different configuration for its respective body portion; each of said mold halves including a flat face extending outwardly from the sides and one end of their respective cavities, and an end face plate extending radially outwardly from the other end of the mold cavity, perpendicularly to said flat face, said mold halves defining an opening into their mold cavitites through said end face plate when said mold halves are placed in juxtaposition to each other, whereby said settable liquid mold material can be poured into the mold cavity to form a toy figurine.
Claim 2
Dependent Claim 300 words
A mold assembly for use in making molded toy figurines from a settable liquid mold material, said assembly comprising a pair of mold halves and a plurality of interchangeable mold elements adapted to be respectively removably mounted in one of said mold halves, said mold halves and said interchangeable mold elements having cooperating mold cavities of distinct configuration defining a toy figurine mold when said mold halves are placed in juxtaposition with said cavities facing each other; the cavity of said one mold half including an integrally formed first cavity portion corresponding to a portion of the configuration of the figurine to be formed and a second cavity portion for removably and interchangeably receiving at least one of said mold elements therein, whereby a portion of the configuration of the side of the figurine formed by said one mold half may be varied by selectively interchanging the mold elements received in said second cavity portion; said second cavity portion being dimensioned to receive at least two of said interchangeable mold elements and said interchangeable mold elements defining at least two groups of mold elements, corresponding respectively to at least two body portions of the figurines to be formed, with each mold cavity in said elements having a different configuration for its respective body portion; each of said mold halves including a flat face extending outwardly from the sides and one end of their respective cavities, and an end face plate extending radially outwardly from the other end of the mold cavity, perpendicularly to said flat face, said mold halves defining an opening into their mold cavitites through said end face plate when said mold halves are placed in juxtaposition to each other, whereby said settable liquid mold material can be poured into the mold cavity to form a toy figurine.
Claim 3
Dependent Claim 27 words
The mold assembly as defined in claim 1 wherein the mold cavities and said interchangeable mold elements are configured to define different body portions of different figurines.
Claim 4
Dependent Claim 34 words
The mold assembly as defined in claim 1 wherein said one mold half and said mold elements have cooperating key members for locating said interchangeable mold elements in their proper configuration in said receptacle.
Claim 5
Dependent Claim 67 words
The mold assembly as defined in claim 1 wherein said one mold half and the mold elements in said tow respective groups of mold elements include cooperating key members for positioning the mold elements in their proper position relative to one another and to said integrally formed first cavity in said one mold half, anD with respect to the mold cavity in the other said mold halves.
Claim 6
Dependent Claim 29 words
The mold assembly as defined in claim 4 wherein said cooperating key members comprise recesses formed in said one mold half and cooperating projections formed on said mold elements.
Claim 7
Dependent Claim 94 words
The mold assembly as defined in claim 5 wherein said mold elements have substantially identical configurations including similar keying edge portions on their peripheries, said keying projections being formed on said keying edge portions and extend laterally thereof, with the projections on said mold elements in one of said groups being in a different location from the projections of the mold elements in the other of said groups whereby the elements of each group may only be placed in a single location within said second cavity portion in association with their respective cooperating recesses.
Claim 8
Dependent Claim 59 words
The mold assembly as defined in claim 1 including a frustroconically shaped mold holder for receiving said mold halves in juxtaposition to each other, said mold halves having outwardly extending wedge-shaped ribs on each mold half engaging the interior wall surface of said frustronconically shaped holder to hold the mold halves together with the flat faces thereof in engagement.
Claim 9
Dependent Claim 41 words
The mold assembly as defined in claim 7 wherein the outer edges of the flat faces of the mold halves are wedgeshaped and engage the inner wall of said holder, said outer edges having cooperating means for aligning the mold halves.
Claim 10
Dependent Claim 58 words
The mold assembly as defined in claim 7 including a cup having an open mouth and cooperating means on said cup adjacent said open mouth and on said mold halves adjacent the periphery of said end face plates for sealing said cup and mold halves together to prevent inadvertent discharge of the contents of the mold when shaken.
