Description

Technical Field

[0001] This utility model relates to the field of tableware technology, and in particular to a stain-resistant melamine tableware. Background Technology

[0002] Melamine tableware is a type of tableware made from melamine resin through high-temperature and high-pressure molding. It boasts advantages such as hardness, vibrant colors, diverse shapes, drop and wear resistance, high-temperature resistance, and easy cleaning. It is widely used in homes, schools, restaurants, and various public catering establishments. While resembling ceramic in appearance, it is lighter and more durable, less prone to breakage, and contains no toxic components, meeting food contact safety standards. Melamine tableware combines practicality and aesthetics, enhancing the dining experience while facilitating mass production and long-term use, making it an ideal environmentally friendly tableware choice for the modern catering industry.

[0003] Traditional melamine tableware is made of a single melamine resin material through injection molding, resulting in a dense and smooth surface structure but lacking an effective anti-seepage coating. During long-term use, it easily absorbs high-pigment seasonings such as curry and soy sauce, causing pigments to seep into the micropores and appear as stubborn stains, affecting both appearance and hygiene. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that lack a waterproof coating.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a stain-resistant melamine tableware, comprising a substrate, the substrate comprising: a substrate, a base made of melamine material, for core support; a ceramic layer wrapped around the outside of the substrate, wherein during manufacturing, a dense, non-porous protective film is sprayed onto the surface of the substrate and cured at high temperature to form the ceramic layer, for preventing liquid penetration and seasoning staining; and a lotus leaf-like layer etched on the surface of the ceramic layer, for giving the material surface a roughness similar to that of a lotus leaf, increasing the liquid contact angle, and reducing oil residue.

[0006] In at least some embodiments, the substrate is circular, and the substrate is divided into a base and a spiral rod. During manufacturing, the spiral rod is cut out in an arc shape in the softened state of the substrate, and the spiral rod is then pulled up.

[0007] In at least some embodiments, multiple spiral rods are provided, and the multiple spiral rods are arranged in a circumferentially uniform array outside the chassis.

[0008] In at least some embodiments, the chassis and the helical rod are integrated, and a support member is sleeved between adjacent helical rods.

[0009] In at least some embodiments, the support members are provided in multiples for dividing and supporting adjacent helical rods.

[0010] In at least some embodiments, the support member includes a support block, the support block having a first through groove and a second through groove respectively provided on the upper and lower sides for passing through two adjacent helical rods.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This invention utilizes a high-density ceramic layer to block pigment penetration, preventing residues of soy sauce, curry, and other coloring seasonings on the surface, fundamentally addressing the pain points of melamine tableware being easily stained and difficult to clean. The introduction of a lotus leaf-like layer structure further enhances the surface's superhydrophobicity, significantly reducing liquid residue and keeping the tableware surface clean, thus extending its lifespan. Furthermore, the innovative spiral rod support structure and modular support blocks effectively improve the overall structural strength and load-bearing capacity, making it suitable for stacking, folding, or multi-layer tableware assembly, expanding functional boundaries and enhancing flexibility and scalability. The overall manufacturing process is simple, with a one-piece molded structure that is both aesthetically pleasing and practical, making it particularly suitable for the promotion of high-end, reusable, and environmentally friendly tableware in the market.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example, according to Figures 1-4 ,like Figure 1 As shown in the figure, the present invention provides a stain-resistant melamine tableware, which, based on the synergistic effect of a multi-layer structure, mainly achieves its stain-resistant and impermeable function through physical barriers and biomimetic surface design, effectively solving the problems of traditional melamine tableware being easily stained and difficult to clean.

[0022] The substrate includes a substrate 4, which is a base made of melamine material and is used for core support. First, the substrate 4 is made of traditional melamine material and serves as the core support structure of the tableware. It has excellent mechanical strength, thermal stability and molding and processing performance, providing the tableware with strong deformation resistance and high temperature resistance. Although traditional melamine is dense, it still has tiny pores, which easily adsorb high pigment seasonings, leading to staining and residue problems.

[0023] To address this issue, the ceramic layer 5, which wraps around the substrate 4, is formed by spraying and high-temperature curing a dense, non-porous protective film onto the surface of the substrate 4. This ceramic layer 5 is used to prevent liquid penetration and seasoning staining. It is composed of nano-scale inorganic oxide materials, has extremely low porosity and high surface density, and can effectively block moisture and pigment molecules in highly permeable seasonings such as curry and soy sauce from penetrating downwards, thus acting as the first line of defense. At the same time, it has high hardness and scratch resistance, which helps to maintain surface cleanliness and service life.

[0024] The lotus leaf-like layer 6, etched on the surface of ceramic layer 5, has a micron-level uneven structure that simulates the microscopic morphology of a natural lotus leaf surface, giving the surface superhydrophobic properties. This gives the material surface a roughness similar to that of a lotus leaf, increasing the liquid contact angle and reducing oil residue. When liquid or oil comes into contact with this surface, it will form a spherical rolling state due to the increased contact angle, significantly reducing adhesion and thus achieving a self-cleaning effect. Droplets are not easy to stay, and seasoning oil stains are difficult to adhere to, making the cleaning process easier and leaving no stains.

[0025] Furthermore, the melamine support layer ensures structural strength, the ceramic protective layer prevents seepage, and the lotus leaf-like layer 6 provides anti-adhesion capability. The integration of these three functional layers significantly improves the stain resistance and hygiene performance of melamine tableware.

[0026] like Figure 1 , Figure 3 and Figure 4As shown, in this embodiment, by dividing the substrate into a base plate 1 and multiple spiral rods 2, and setting support members 3 between them, the purpose of enhancing structural stability and functional versatility is achieved. Based on the synergistic cooperation of material thermoforming technology and spiral lifting structure design, the tableware not only has basic serving functions, but also good support, load-bearing capacity, or expandable connection functions, which is different from the traditional single planar structure of melamine substrate 4.

[0027] The substrate 4 is circular. During processing, melamine material is first injection molded into a circular substrate 4, which is then divided into a base plate 1 and a spiral rod 2. During manufacturing, the spiral rod 2 is cut in an arc shape while the substrate 4 is in a softened state. When the material is in a thermally softened state, multiple slender segments with a spiral geometry are cut along the outer periphery of the substrate 4 using a precision arc cutting process. These segments are the spiral rods 2. The spiral rods 2 are then raised. Multiple spiral rods 2 are formed and arranged in a circumferentially uniform array outside the base plate 1. The base plate 1 and the spiral rods... 2. Integrated design: After cutting, these spiral rods 2 are "lifted" from the plane of the substrate 4 to a certain height through a lifting process, forming a spiral structure with elastic deformation or three-dimensional support capabilities. Multiple spiral rods 2 are evenly arranged around the outside of the chassis 1 in a circumferential array to ensure symmetrical mechanical distribution and prevent structural overload or instability. Support members 3 are sleeved between adjacent spiral rods 2. The support members 3 can adopt transverse connecting rods, buckles or flexible clamping structures to enhance the overall structural rigidity and prevent the spiral rods 2 from deforming due to excessive force.

[0028] The above structure is suitable for heavy-duty tray tableware, portable foldable tableware systems, or multi-layer modular tableware. Through the structural design of the spiral rod 2, it achieves three-dimensional space utilization and adaptive connection of tableware components, while enhancing overall stability and durability. It represents a significant optimization and functional expansion of traditional melamine tableware structures.

[0029] In this embodiment, multiple support members 3 are provided to divide and support adjacent spiral rods 2. The support member 3 includes a support block 301. The support block 301 has a first through groove 302 and a second through groove 303 for passing through two adjacent spiral rods 2, respectively, on the upper and lower sides. By setting multiple support blocks 301, adjacent spiral rods 2 are effectively divided and stabilized, thereby improving the structural stability and durability of the entire device.

[0030] Specifically, the first through slot 302 is located on the upper part of the support block 301, and the second through slot 303 is located on the lower part. The two through slots are arranged vertically. Through reasonable size matching, they can ensure interference or tight fit with the screw rod 2 to form a stable connection. During operation, multiple support blocks 301 are evenly installed between adjacent screw rods 2. They not only play a role in lateral limiting and vertical stabilization of the screw rod 2, but also bear part of the load when the overall structure is under stress, preventing the screw rod 2 from twisting or bending due to concentrated force.

[0031] The working principle of this utility model is as follows: It achieves both anti-pollution and structural reinforcement functions through a three-layer synergistic design. The melamine substrate 4 serves as the core support, possessing high strength and thermal stability. Its surface is coated with a highly dense nano-ceramic protective layer, effectively blocking the penetration of moisture and pigments in seasonings. The ceramic layer 5 is further etched to form a lotus leaf-like microstructure, imparting superhydrophobicity, making it difficult for oily liquids to adhere and allowing them to roll off automatically, achieving self-cleaning. Simultaneously, in terms of structural design, the substrate 4 adopts a circular structure and is divided into a base 1 and multiple spiral rods 2. The spiral rods 2 are raised through a thermal softening arc-cutting process to form a three-dimensional support array structure, which is laterally connected and stabilized by multiple sets of support blocks 301. The support blocks 301 have through slots penetrating adjacent spiral rods 2, enhancing the overall uniformity of force distribution, resistance to deformation, and modular structural performance, thus combining anti-pollution, structural support, and multi-functional expansion capabilities.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
