Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
160 words
A sand painting unit comprising an outer container member having a continuous transparent upstanding wall and a bottom horizontal wall connected to said upstanding wall, an inner container having a continuous upstanding wall and a bottom horizontal wall connected to said last mentioned upstanding wall, said bottom wall of said outer container having means for receiving and positioning the inner container relative to said outer container so that the upstanding wall of said inner container is spaced from the upstanding wall of said outer container to define a reduced width area between said upstanding walls, said reduced width area being closed at the bottom and open at the top, said reduced width area forming a container means receiving and retaining grains of sand, some of which are in various colors so that when said grains of sand are blended, interspersed and/or mixed, pictures or designs may be formed therefrom and viewed through said upstanding walls of said outer container member.
Claim 2
Dependent Claim

A sand painting unit comprising an outer container member having a continuous transparent upstanding wall and a bottom horizontal wall connected to said upstanding wall, an inner container having a continuous upstanding wall and a bottom horizontal wall connected to said last mentioned upstanding wall, said bottom wall of said outer container having means for receiving and positioning the inner container relative to said outer container so that the upstanding wall of said inner container is spaced from the upstanding wall of said outer container to define a reduced width area between said upstanding walls, said reduced width area being closed at the bottom and open at the top, said reduced width area forming a container means receiving and retaining grains of sand, some of which are in various colors so that when said grains of sand are blended, interspersed and/or mixed, pictures or designs may be formed therefrom and viewed through said upstanding walls of said outer container member.
Claim 3
Dependent Claim
68 words
A sand painting unit as set forth in claim 1 in which the outer container member has a plurality of transparent upstanding walls and in which the inner container has a corresponding plurality of upstanding walls, with said corresponding inner upstanding walls parallel to said outer upstanding walls and spaced therefrom, and with said corresponding upstanding walls of said outer and inner containers providing the reduced width areas.
Claim 4
Dependent Claim
86 words
A sand painting unit as set forth in claim 1 in which the outer container member is a box-shaped unit having a plurality of transparent sides forming the continuous transparent upstanding wall and the inner container is a box-shaped unit of smaller dimensions having a corresponding plurality of sides forming the continuous upstanding wall, each pair of outer and inner sides being parallel and defining a reduced width area therebetween, with each of said reduced width areas forming a container for the purpose as set forth.
Claim 5
Dependent Claim
40 words
