Description

The present invention relates to a paper-made hollow solid jigsaw puzzle, and in particular, it is widely applied to jigsaw puzzles and similar structures, and trains users' thoughts on 3D solid concepts and allows them to understand what the real thing is. The present invention relates to various hollow products made by combining paper materials.

Regarding a conventional paper-made three-dimensional jigsaw puzzle, Taiwan Patent No. 93215926 discloses a “hollow three-dimensional jigsaw puzzle structure using a paper board”. This structure is made of paper board material, divided into a plurality of three-dimensional puzzle pieces according to the outer shape of the actual surface of the object, and each puzzle piece is provided with uneven edges to be connected to each other and adjacent puzzles When connected to the pieces and all the puzzle pieces are connected, a hollow three-dimensional structure that matches the surface of the actual object is formed. However, a conventional plate-like puzzle piece is formed by cutting a large thick paper board and pressing it with a concave die and a convex die to form a plate-like puzzle block with a fixed arc degree. Therefore, the paper material is not soft and cannot be bent, and the outer shape of the structure formed therefrom cannot be deformed. Also, the hollow three-dimensional jigsaw puzzle structure of the paper board is a method in which the connection method of each puzzle piece is a method of applying an interference fit by applying pressure to the connection part, so the structural strength of the finished product after connection is weak, There is a possibility of disconnection.
