Anti-detachment composite cutting board

Abstract

In the field of kitchen utensil technology, we provide a composite cutting board with a detachment prevention mechanism. [Solution] The cutting board includes a plastic plate body 1 and a metal plate 2. The edge of the metal plate is provided with a flange equipped with a connecting ring, and the flange and / or connecting ring are embedded in the plastic plate body. Embedded ribs with through holes are fixed to the bottom surface of the metal plate, and plastic is filled into the through holes during injection molding to form a connecting structure. The physical edge fixing by the connecting ring and the rivet-like double fixing structure by the plastic filled into the through holes significantly strengthen the bonding force between the metal and plastic, effectively preventing delamination due to thermal expansion / collapse or external impact. Furthermore, the flange structure seals the edge, increasing safety during use. It can be applied to single-layer or double-layer metal plate structures, and in particular, when two types of materials, titanium and stainless steel, are combined, it combines antibacterial properties and high strength, significantly extending the lifespan of the cutting board. The purpose is to solve the technical problems of conventional composite cutting boards, such as the metal surface easily peeling off and dirt accumulating on the edges.

Description

Technical Field

[0001] This utility model relates to the technical field of kitchen utensils, and particularly to a non-detachable composite cutting board.

Background Art

[0002] A cutting board is an essential kitchen utensil in daily life. Conventional wooden or bamboo cutting boards are prone to mold growth, chipping, and are difficult to clean. Plastic cutting boards are easily scratched and soiled during use, and are also inferior in heat resistance.

[0003] To solve the above problems, a composite cutting board combining metal and plastic has emerged in the prior art. Generally, a method of injection molding a plastic layer on a metal plate or joining a metal plate on a plastic substrate is adopted. However, the existing composite cutting boards have the following drawbacks. Insufficient adhesive strength: Due to the large difference in the thermal expansion coefficients of metal and plastic, the metal plate is likely to peel off and fall off from the plastic substrate due to repeated heating and cooling or stress during cutting. Improper edge treatment: The metal edge is exposed or simply covered, which not only poses a risk of hand injury, but also allows moisture and food residues to fall into the gap at the joint, facilitating bacterial growth. Single structure: Most are single-layer metal structures, which cannot simultaneously meet the requirements of the safety of the food contact surface (such as antibacterial properties) and the overall support strength. Therefore, there is a strong demand for a new composite cutting board with structural stability, preventing peeling and falling off, and having safety during use.

Summary of the Invention

[0004] The object of this utility model is to provide a non-detachable composite cutting board for solving the problems in the prior art that the bonding between the metal plate and the plastic substrate is insufficient, prone to falling off and bulging, and prone to dirt accumulation at the edges.

[0005] To achieve the above objective, this utility model employs the following technologies. The detachment prevention type composite cutting board includes a plastic plate body (1) and a metal plate (2) installed on the upper side of the plastic plate body (1). A flange (21) is provided on the edge of the metal plate (2), which is bent toward the plastic plate body, and the bottom of the flange (21) is folded inward to form a connecting ring (22). The connecting ring (22) is embedded inside the plastic plate body (1) and is integrated with the plastic plate body (1) by injection molding. At least one embedded rib (23) is fixed to the surface of the metal plate (2) facing the plastic plate body (1), and the embedded rib (23) is fitted into the interior of the plastic plate body (1), thereby suppressing deformation and displacement of the metal plate (2). The embedded rib (23) is provided with at least one through hole (231), and the plastic material of the plastic plate body (1) is filled and solidified in the through hole (231), thereby connecting and fixing the embedded rib (23) and the plastic plate body (1), and suppressing deformation and bulging of the metal plate (2).

[0006] As a further optimization of this utility model, the embedded ribs (23) are arranged in a stripe, mesh, or ring pattern.

[0007] The flange (21) encloses the outer surface of the plastic plate body (1) and constitutes a metal edging structure. Alternatively, the flange (21) is embedded within the plastic plate body (1), and both the inner and outer walls of the flange (21) are integrated with the plastic plate body (1) by injection molding.

[0008] A plastic handle (3) is integrally injection-molded onto one side of the plastic plate body (1).

[0009] This utility model also proposes other technical means. The detachment prevention type composite cutting board includes a plastic plate body (1) and a composite metal plate. The composite metal plate includes an upper metal plate (2a) placed on top of the plastic plate body (1) and a lower metal plate (2b) placed below the plastic plate body (1). The edges of the upper metal plate (2a) and the lower metal plate (2b) are both provided with flanges (21) that are bent toward the plastic plate body, and the bottom of the flanges (21) is folded inward to form a connecting ring (22). The connecting ring (22) is embedded inside the plastic plate body (1) and is integrated with the plastic plate body (1) by injection molding. At least one embedded rib (23) is fixed to the surface of the upper metal plate (2a) and / or lower metal plate (2b) facing the plastic plate body (1), and the embedded rib (23) is fitted into the interior of the plastic plate body (1). The embedded rib (23) is provided with at least one through hole (231), and the plastic material of the plastic plate body (1) is filled and solidified into the through hole (231), thereby connecting and fixing the embedded rib (23) and the plastic plate body (1).

[0010] Furthermore, the upper metal plate (2a) is made of titanium or a titanium alloy for contact with food, and the lower metal plate (2b) is made of stainless steel for support.

[0011] The cutting board may further include a metal handle (4). The metal handle (4) may be welded to the outer wall of the flange (21), or the metal handle (4) may be embedded in the plastic plate body (1) and integrated with the plastic plate body (1) by injection molding.

[0012] The effects of this utility model are as follows: Multi-layered fixing structure: The quadruple structure of flange + connecting ring + embedded rib + through hole allows plastic to flow into the through hole during injection molding, forming a plastic rivet. This firmly fixes the metal plate to the plastic plate body, fundamentally solving the problem of detachment due to thermal expansion and contraction. Fully sealed coating: The flange and connecting ring design not only enhances the bonding strength but also seals the metal edges to prevent dirt accumulation, resulting in a smooth feel that won't hurt your hands. Functional Optimization: The double-sided metal design allows for cutting cooked foods, vegetables, and fruits using biocompatible titanium on one side, and raw meat and bone cutting using high-strength stainless steel on the other side, achieving both health and durability.

The main body is a plastic board body (1), and a metal plate (2) is laminated on the upper surface of the plastic board body. The metal plate preferably adopts a 304 stainless steel or titanium alloy material. The edge of the metal plate (2) is bent downward to form a flange (21), and the lower part of the flange (21) is bent horizontally inward to form a connecting ring (22). During injection molding, the plastic melts and wraps the flange (21) and the connecting ring (22). After cooling, the flange (21) and the connecting ring (22) are completely fixed inside the plastic board body (1), serving as the first anti-separation means.

[0016] On the lower surface (the surface facing the plastic) of the metal plate (2), an embedded rib (23) is fixed by spot welding. The embedded rib (23) is designed in a circular shape and may also be in a stripe shape or a mesh shape. A plurality of through holes (231) are opened in the embedded rib (23). During injection molding, the liquid plastic fills the through holes (231), and after solidification, plastic columns are formed to integrally connect the metal embedded rib (23) and the plastic board body (1), serving as the second anti-separation means to suppress the deformation and swelling of the metal plate.

[0017] Also, a plastic handle (3) is formed on one side of the plastic board body (1) by integral injection molding, which is easy to hold and has a heat insulation and anti-scalding effect.

It includes a plastic board body (1), an upper layer metal plate (2a) installed on the upper side, and a lower layer metal plate (2b) installed on the lower side. The upper layer metal plate (2a) adopts a titanium or titanium alloy material and has excellent biocompatibility and antibacterial properties, so it is suitable for direct contact with cooked food and fruits. The lower layer metal plate (2b) adopts a 430 or 304 stainless steel material and provides strong support force, being suitable for bone cutting.

[0019] Both the upper and lower metal plates are provided with flanges (21) and connecting rings (22), which are connected and fixed to the plastic plate body (1) via embedded ribs (23) to suppress deformation and bulging of the metal plates.

[0020] In this embodiment, the flanges (21) of both the upper and lower metal plates enclose the outside of the plastic plate body (1), forming a complete metal edging, which is aesthetically pleasing and highly wear-resistant. Metal handles (4) are provided on the sides, and these metal handles (4) are directly welded to the flanges (21).

[0021] Refer to Figures 7 and 8. This embodiment 3 is a rectangular double-sided composite metal cutting board with a detachment prevention mechanism, proposing a double-sided detachment prevention type composite cutting board. The difference from embodiment 2 is that the metal handle (4) is embedded in the mold before injection molding, and the metal handle is integrated with the plastic plate body (1) by injection molding.
