Benefits of technology
"The invention is a three-dimensional puzzle made up of a lenticular lens layer with ink layers applied to its flat surface. The invention also includes a method for manufacturing the puzzle by exposing the ink layers to ultraviolet light and adding a layer of opaque ink. A white paper backing is then adhered to the opaque ink layer, and a backer board is applied on top of the paper backing. The invention also includes a method for cutting the puzzle by providing a cutting platform with a groove for the shape of a puzzle piece, positioning a cutting instrument in the groove, and pressing the three-dimensional puzzle over the cutting instrument to cut it into at least one piece."
Problems solved by technology
A three-dimensional puzzle gives the added dimension of depth to the scene, thereby making it more difficult to construct.
Three-dimensional puzzles that can be cut into several small pieces, such as a 500 piece puzzle set, are not well known, however.
The greater pressure involved in cutting a puzzle into numerous small pieces causes the backing board to weaken, thus causing the images on the puzzle pieces to delaminate.
This decreases the sharpness of the image and results in cloudy condition on the edges of the puzzle piece.

Embodiment Construction
[0014] The following examples further illustrate the invention but, of course, should not be construed as in any way limiting its scope. As shown in FIGS. 1-3, the invention involves a puzzle 10 comprised of a lenticular lens layer 12 having a lens surface 14 and a flat surface 16. A layer of four colors of ink 18 is applied to the flat surface 16, and a layer of opaque ink 20 applied to the four colors of ink 18. A white paper backing 22 is adhered to the layer of opaque ink 20 using an emulsion-based adhesive having a viscosity of approximately 1,600 mPas at 23° C., and a backer board 24 comprised of four layers of cardboard is applied to the white paper backing 22.
[0015] In one embodiment, the puzzle 10 is further comprised of a layer of primer 26 located between the flat surface 16 of the lenticular lens layer 12 and the layer of four colors of ink 18. The primer is a UV / EB Curable adhesive, primer, coating that is sold under various trade names including Rad-Cure, Rad-Kote and...

Abstract
A three-dimensional puzzle including a lenticular lens layer having a lens surface and a flat surface. A four color ink is applied to the flat surface and a layer of opaque ink is applied to the four color ink. A white paper backing is adhered to the layer of opaque ink using an emulsion based adhesive having a viscosity of approximately 1,600 mPas at 23° C., and a backer board comprised of four layers of cardboard is applied to the white paper backing. A method of manufacturing the three-dimensional puzzle is also disclosed.
Description
CROSS-REFERENCE TO RELATED PATENT APPLICATION [0001] This patent application is a divisional of copending U.S. patent application Ser. No. 10 / 993,120, filed Nov. 19, 2004, the content of which is incorporated herein by reference in its entirety for all purposes.FIELD OF THE INVENTION [0002] This invention pertains to puzzles in general and, more particularly, to three-dimensional puzzles. BACKGROUND OF THE INVENTION [0003] Puzzles have long been a source of entertainment and enjoyment for individuals both young and old. For the youngest child, puzzles which usually involve a few large pieces, serve not only as entertainment, but also help to develop coordination along with color and shape recognition. As children get older, puzzles with many smaller pieces become popular as they offer more of a challenge to build than puzzles with large pieces. [0004] Because the pieces of a puzzle can only be cut so small in order for the puzzle to be practical to construct, puzzle manufacturers mu...
