Problems solved by technology

In the prior art, puzzles are usually made of wood or paper materials, which are not only easy to burn, but also have poor water and dirt resistance
For this reason, the jigsaw puzzle of EVA material has also been developed in the prior art, but its shortcoming is that it is easy to deform, and as a foaming material, it usually produces a gas similar to ammonia taste, which may bring harm to children's health. Certain hidden dangers, so it is necessary to provide an environmentally friendly, healthy, tasteless EVA environmental protection jigsaw puzzle toy

Abstract

The invention relates to an EVA (ethylene vinyl acetate) environment-friendly jigsaw puzzle, and belongs to the technical field of manufacturing of a toy for children. The EVA environment-friendly jigsaw puzzle comprises a plurality of units, wherein each unit comprises a main body which is made from an EVA composition material, and partial patterns are printed on at least one of the upper main surface and the lower main surface of the main body; the main body additionally has an outer circumferential side surface; a negative tenon structure which sinks inwards is formed on the outer circumferential side surface, and a positive tenon structure which is protruded outwards is additionally formed on the outer circumferential side surface; and by virtue of the negative tenon structure and the positive tenon structure, the multiple units can be spliced together in a detachable mode, so as to form a complete pattern on at least one of the upper main surface and the lower main surface of the main body. The EVA environment-friendly jigsaw puzzle disclosed by the invention is not only free from toxicity or odor and is consistent with requirements of toys for children on health and environmental protection, but also soft in texture, good in flame retardance and excellent in wear resistance and durability.

Description

technical field [0001] The invention belongs to the technical field of children's toy manufacturing, and more specifically, the invention relates to an EVA environment-friendly jigsaw puzzle toy. Background technique [0002] Toys are an indispensable item in children's life. It accompanies children's growth, adds fun to children's life, and can also enlighten wisdom.
