Description

Technical Field

[0001] The utility model relates to the technical field of cutting boards, in particular to a chemical micro-foamed sandwich structure cutting board. Background Art

[0002] A cutting board, also known as a chopping board, is a wooden board placed on a table to prevent damage when cutting vegetables. It's commonly called a "chopping board" and written as a "chopping board." Traditionally, cutting boards were made of wood, but due to their ease of wear and tear, they are now often cast in plastic. To prevent cracking from improper storage, avoid soaking cutting boards in water or direct sunlight for extended periods. They should also not be left in a well-ventilated area for extended periods. Once air-dried, bring them indoors. After use, wipe them clean with a clean cloth and then dry them with a dry cloth before storing.

[0003] Most of the plastic cutting boards currently on the market are made of a whole piece of plastic. If the board is too thin, the cutting effect will be poor. If the board is too thick, although the cutting effect is improved, the cutting board is too heavy and inconvenient to use. In addition, the thickness of this cutting board leads to a long molding cycle and difficulty in achieving flatness, which will also result in high manufacturing costs and poor user experience. In addition, the cutting boards on the market will have moisture when cutting vegetables, and the moisture will overflow everywhere, affecting the cutting effect.

[0004] Therefore, in response to the above problems, the existing cutting board technology needs to be further improved. Utility Model Content

[0005] The purpose of the utility model is to overcome the problems of existing cutting board technology, such as cutting boards being too thin and not durable, being too thick and bulky, being costly, and overflowing with water; by rationalizing the design of cutting board technology, adopting a cutting board body, a cutting board handle, anti-slip protrusions and a water groove, as well as a hard layer and an inner filling layer, etc., an one-piece cutting board can be realized, which is convenient to use, more resistant to water storage and prevents water overflow, avoiding slipping when cutting vegetables, etc.

[0026] This invention is a cutting board body that is directly injection molded in one step through a chemical micro-foaming process. Without affecting the appearance of the cutting board, many bubbles are generated inside the cutting board, forming a solid skin layer on the upper and lower outer layers and a foamed core layer structure.
