Description

Technical Field

[0001] This utility model relates to a melamine utensil, and more particularly to a melamine utensil with a wood grain pattern. Background Technology

[0002] Melamine resin is widely used in the manufacture of various tableware, such as bowls, plates, and cups, due to its excellent properties such as heat resistance, impact resistance, light weight, and ease of dyeing and printing.

[0003] Traditional melamine containers typically achieve their surface patterns by attaching a layer of pre-printed melamine decal paper. Specifically, during the molding process, the decal paper is placed in a mold, covered with melamine molding powder, and then bonded to the melamine matrix under high temperature and pressure.

[0004] While the aforementioned technologies are mature, their patterns are limited to two-dimensional printing, lacking a sense of three-dimensionality and depth. The patterns are also relatively standardized, unable to reproduce the random, unique textures of natural wood or stone. However, modern consumers have an increasing demand for higher-quality tableware with more sophisticated designs and natural textures, which traditional decal techniques can no longer meet. To overcome these shortcomings, the industry has experimented with mixing color powder or particles into melamine raw materials to mimic the grain of stone or wood.

[0005] However, the textures produced by this method are usually blurry and unnatural, lacking a true fibrous feel and depth. The randomness and layering of the textures are limited, making it difficult to truly rival the complexity and delicacy of natural wood grain. In addition, the added colorants can only simulate color, but cannot provide the warm touch and visual depth unique to natural materials (such as wood).

[0006] Therefore, how to develop a simple manufacturing process that can give melamine utensils realistic, three-dimensional and unique natural wood grain patterns has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0007] The main purpose of this utility model is to provide a melamine utensil with a wood grain pattern, aiming to solve the problem of the lack of natural texture in the existing melamine utensil patterns. The melamine utensil is a one-piece molded body, and its longitudinal section structure includes an outer beautifying layer and an inner core layer stacked sequentially from the outside to the inside. The outer beautifying layer is composed of melamine resin gloss powder, which gives the utensil a transparent and glossy surface. The inner core layer is composed of a melamine matrix and a plurality of wood and / or bamboo particles embedded therein and randomly distributed. This allows the natural texture and color of the wood and / or bamboo particles to penetrate through the inner core layer and be exposed on the inner and outer surfaces and the perimeter of the opening of the utensil, thereby forming a wood grain pattern with three-dimensional depth and random natural texture, giving the melamine utensil a warm and solid wood feel and a unique visual aesthetic.

[0008] To achieve the above objectives, this utility model provides a melamine vessel with a wood grain pattern. The melamine vessel is characterized in that it is a one-piece molded body comprising an inner surface, an outer surface, and an opening. The longitudinal section of the melamine vessel includes an outer beautifying layer with a transparent glossy surface and an inner layer with a three-dimensional depth and a random natural wood grain pattern, sequentially stacked from the outside to the inside. The outer beautifying layer is composed of melamine resin gloss powder. The inner layer comprises a melamine matrix and a plurality of wood and / or bamboo particles embedded and randomly distributed within the melamine matrix. The natural texture and color of the wood and / or bamboo particles in the inner layer can penetrate the outer beautifying layer and be revealed. The wood grain pattern is at least partially revealed on the inner surface, the outer surface, and the periphery of the opening of the melamine vessel.

[0009] In a preferred embodiment of the present invention, the inner layer of the melamine vessel contains a plurality of wood and / or bamboo particles that are irregularly shaped and of varying sizes.

[0010] In a preferred embodiment of this utility model, the melamine vessel is a bowl, cup, plate, pot, pan, or cylinder.

[0011] In a preferred embodiment of this utility model, the melamine vessel is formed by hot pressing using a hot pressing process and a hot pressing mold.

[0012] In a preferred embodiment of the present invention, the melamine matrix in the inner layer of the melamine vessel is further composed of a plurality of colored melamine powders and / or granules and melamine resin gloss powder.

[0013] In a preferred embodiment of the present invention, the proportions of melamine resin gloss powder, wood and / or bamboo particles, and a plurality of melamine powders and / or particles in the melamine container by weight percentage are 20 to 50%, 25 to 40%, and 25 to 40%, respectively.

Detailed Implementation

[0023] With reference to the accompanying drawings, the structure and technical features of this utility model are described in detail below. The accompanying drawings are only used to illustrate the structural relationships and related functions of this utility model. Therefore, the dimensions of the components in the accompanying drawings are not drawn to actual scale and are not intended to limit this utility model.

[0024] Please refer to Figure 1As shown, this utility model provides a melamine utensil 10 with a wood grain pattern. The melamine utensil 10 is a one-piece molded body, which includes an inner surface 11, an outer surface 12, and an opening 13. The melamine utensil 10 can be various utensils commonly used in the catering industry, such as bowls, cups, plates, pots, pans, or tubes, but is not limited. Taking a bowl-shaped utensil as an example, it has a recessed space for holding items, which is defined by the inner surface 11. The utensil also has the outer surface 12 that contacts the outside, and the opening 13 located at the top, but is not limited. The inner surface 11 of the melamine utensil 10 further includes an inner bottom surface and an inner edge surface, and the inner edge surface extends upward from the inner bottom surface, but is not limited. The outer surface 12 of the melamine utensil 10 further includes an outer bottom surface and an outer edge surface, and the outer edge surface extends upward from the outer bottom surface, but is not limited.

[0025] Please refer to Figure 2 As shown, the longitudinal section of the melamine vessel 10 includes an outer beautifying layer 14 with a transparent glossy surface and an inner layer 15 with a three-dimensional depth and a random natural texture wood grain pattern, which are stacked sequentially from the outside to the inside.

[0026] Please refer to Figure 2 As shown, the outer beautifying layer 14 is located on the outermost surface of the vessel, completely covering the inner layer 15. The outer beautifying layer 14 is composed of melamine resin gloss powder 20. After this gloss powder is melted under high temperature and pressure, it forms a protective layer with high transparency, high hardness, and high gloss. In addition, the outer beautifying layer 14 not only protects the internal texture from wear, but more importantly, its transparency allows light to pass through, enabling the wood grain pattern of the inner layer 15 to be displayed without reservation, producing a crystal-clear visual effect and enhancing the overall texture.

[0027] Please refer to Figure 2 As shown, the endoderm 15 is a functional layer that constitutes the main body of the vessel and produces the wood grain pattern. The endoderm 15 is composed of a melamine matrix 30, which serves as a basic binder and filler, covering and fixing the wood / bamboo particles 40.

[0028] Please refer to Figure 2 As shown, in a preferred embodiment, in order to make the background color of the wood grain pattern richer or more contrasting, the melamine matrix 30 itself can be composed of a plurality of colored melamine powders and / or granules 50 mixed with melamine resin gloss powder 20, but is not limited thereto. For example, dark brown melamine powder can be used to match the original wood-colored wood chips to simulate the texture of dark hardwood; wherein the wood and / or bamboo particles 40 are the core elements for forming the unique wood grain.

[0029] Please refer to Figure 2As shown, the outer beautifying layer 14 is composed of melamine resin gloss powder 20; wherein the inner layer 15 comprises a melamine matrix 30 and a plurality of wood and / or bamboo particles 40 embedded and randomly distributed in the melamine matrix 30, and the natural texture and color of the wood and / or bamboo particles in the inner layer 15 can penetrate the outer beautifying layer 14 through the inner layer 15 and be revealed. Figure 2 As shown; wherein the wood grain pattern is at least partially exposed on the inner surface 11 of the melamine vessel 10 (e.g. Figure 3 and 4 As shown), the outer surface 12 (as shown) Figure 3 and 5 (as shown) and the opening 13 (as shown) Figure 3 and 4 On the periphery of (as shown).

[0030] Please refer to Figure 1 As shown, the structural features of this utility model enable the wood grain pattern to be presented continuously on all the aforementioned surfaces, including the inner bottom surface, inner edge surface, outer bottom surface, outer edge surface, and even around the topmost opening 13, achieving a visual sense of wholeness and immersion.

[0031] Please refer to Figure 2 As shown, the inner layer 15 of the melamine vessel 10 contains a plurality of wood and / or bamboo particles 40, which are a plurality of irregularly shaped and differently sized fragments. These particles are obtained by physically crushing natural wood or bamboo (or a mixture of both). Their irregular shape and different size are key to ensuring that after being mixed with the melamine matrix 30, a completely random and non-repetitive natural texture can be formed. Furthermore, during the molding process of the melamine vessel 10, multiple wood and / or bamboo particles 40 are compacted and embedded in the melamine matrix 30 under high pressure. The natural fiber texture and color differences of the multiple wood and / or bamboo particles 40 are interwoven into a wood grain pattern with rich details and three-dimensional depth due to the different spatial postures (lying flat, upright, tilted) and distribution density of the particles in the matrix. This pattern is not printed on the surface, but extends from the inside of the vessel to the surface. Therefore, the user can observe a continuous and realistic texture from multiple perspectives such as the inner surface 11, the outer surface 12, and the perimeter of the opening 13.

[0032] Please refer to Figure 7 As shown, the melamine vessel 10 is formed by hot pressing using a hot pressing process and a hot pressing mold 2, but this process is not limited, which helps to save on manufacturing costs.

[0033] Please refer to Figure 2As shown, in a preferred embodiment, in order to make the background color of the wood grain pattern richer or more contrasting, the melamine matrix 30 in the inner layer 15 of the melamine vessel 10 is further composed of a plurality of colored melamine powder and / or granules 50 and melamine resin gloss powder 20; wherein, in the weight percentage proportion of the melamine vessel 10, the proportions of melamine resin gloss powder 20, wood and / or bamboo particles 40 and the plurality of melamine powder and / or granules 50 are 20 to 50%, 25 to 40%, and 25 to 40%, respectively, but not limited.

[0034] Next, a preferred embodiment of the melamine utensil 10 of this utility model is disclosed, which discloses a manufacturing method for enriching or enhancing the contrast of the wood grain pattern background color. This manufacturing method includes, but is not limited to, the following steps:

[0035] Step S1: Provide 20g of melamine resin gloss powder, 40g of wood and / or bamboo granules, and a plurality of 50g of melamine powder and / or granules. Figure 6 As shown;

[0036] Step S2: Mix a plurality of melamine powder and / or granules 50, melamine resin gloss powder 20, and wood and / or bamboo granules 40 in a predetermined weight ratio to form a composite material such as Figure 6 As shown; wherein, in the weight percentage proportion of the composite material, the proportions of melamine resin gloss powder 20, wood and / or bamboo particles 40 and a plurality of melamine powder and / or particles 50 in the composite material are 20 to 50%, 25 to 40% and 25 to 40% respectively, but not limited.

[0037] Step S3: Take a predetermined amount of the composite material and place it into a collection mold 1, and preheat the composite material to form a soft preform 10a. Figure 6 As shown.

[0038] Step S4: Transfer the soft preform 10a into a hot press molding die 2 as follows. Figure 7 As shown, the soft preform 10a is molded into a vessel body by applying heat and pressure through a one-time hot pressing process.

[0039] Step S5: Remove the vessel body from the thermoforming mold 2, and after cooling and trimming, a beautiful, durable, and uniquely textured melamine vessel 1 containing wood components is completed. Figure 7As shown; the melamine vessel 1 includes an inner surface 11, an outer surface 12, and an opening 13; the longitudinal section of the melamine vessel 10 includes an outer beautifying layer 14 with a transparent glossy surface and an inner layer 15 with a three-dimensional depth and a random natural texture wood grain pattern, which are stacked sequentially from the outside to the inside; the outer beautifying layer 14 is composed of melamine resin gloss powder 20; the inner layer 15 includes a melamine matrix 30 and a plurality of wood and / or bamboo particles 40 embedded and randomly distributed in the melamine matrix 30, and the melamine matrix 30 is further composed of a plurality of melamine powder and / or granules 50 and melamine resin gloss powder 20.

[0040] Please refer to Figure 6 As shown, in step S2, a plurality of melamine powder and / or granules 50, melamine resin gloss powder 20, and wood and / or bamboo particles 40 are uniformly mixed by stirring to form the composite material. However, this method will cause the wood particles to be randomly and uniformly distributed in the composite material, forming a speckled texture effect similar to terrazzo or granite.

[0041] Please refer to Figure 6 As shown, in step S2, a plurality of melamine powder and / or granules 50 and melamine resin gloss powder 20 are first placed into the collection mold 1, and then wood and / or bamboo particles 40 are laid on top to form the layered composite material, but this is not limited.

[0042] Please refer to Figure 6 As shown, in step S2, wood and / or bamboo particles 40 are first laid on the bottom of the assembly mold 1, and then a plurality of melamine powder and / or particles 50 and melamine resin gloss powder 20 are laid on top to form the layered composite material, but this is not limited.

[0043] The different mixing / laying methods mentioned above will result in significant differences in the density, distribution, and layering of the wood grain in the final product. This allows manufacturers to easily develop multiple product series with different styles to meet the aesthetic needs of different consumers, greatly enriching the product line and enhancing market competitiveness.

[0044] Please refer to Figure 6 As shown, in step S3, the temperature for preheating the composite material is 40℃±1℃, but not limited thereto.

[0045] Please refer to Figure 7 As shown, in step S4, the temperature of the hot pressing mold 2 for one-time hot pressing is 180℃±1℃, but is not limited.

[0046] In summary, this invention, through its unique double-layer structure design and innovative material application that combines irregular natural wood / bamboo particles with a melamine matrix, successfully manufactures melamine tableware with the following beneficial effects:

[0047] (1) Aesthetic uniqueness: It completely breaks away from the flatness and repetitiveness of traditional decals, giving each vessel a unique and unreplicable random natural wood grain, greatly enhancing the artistic value and personalization of the product.

[0048] (2) Visual three-dimensionality: The wood grain pattern is generated from the outside to the inside, with real physical depth and layering. Under light, it can produce rich light and shadow changes, and the visual effect is far superior to surface printing.

[0049] (3) Enhanced texture: The transparent and glossy outer layer combined with the natural wood grain inside gives the plastic utensils a warm and exquisite texture comparable to high-end solid wood or lacquerware.

[0050] (4) Structural integrity: Through one-piece hot pressing molding, the vessel structure is sturdy and durable, and the texture is embedded in the base, so there is no risk of peeling or falling off like decals.

[0051] (5) Clear material ratio disclosure: The clear ratio range provides manufacturers with a clear and repeatable technical path, eliminating the need for huge resources to conduct trial and error, and significantly reducing development costs and time.

[0052] (6) Improved physical toughness of the product: The combination of wood or bamboo particles and resin not only blends evenly, but also avoids the problem of the product becoming brittle due to excessive hardness.

[0053] (7) Use environmentally friendly or natural materials: Wood and / or bamboo pellets are materials that are easily decomposed by nature.

[0054] This invention successfully combines the convenience of the plastics industry with the simple beauty of nature, providing a new and creative direction for the design and manufacture of melamine utensils.
