tableware

Abstract

To provide highly decorative tableware containing dried plant material, which suppresses the occurrence of bubbles and interfacial peeling and has aesthetic quality, adhesion and safety suitable for food use. [Solution] Multiple resin layers are laminated on the inner surface of a vessel-shaped base 1 in the following order: base layer 2, flower arrangement layer, intermediate layer 4, and top coat layer 5, with dried plant material 6, such as pressed flowers, encapsulated within the intermediate layer. When forming the intermediate layer, a degassing process is performed under a negative pressure of -0.1 MPa or higher to remove air bubbles within the plant and resin. After the resin is poured, the base is tilted and rotated to spread the resin evenly across the inner surface, allowing the dried plant material to be beautifully arranged. Furthermore, steps or grooves are formed on the inner surface of the base, allowing the resin to flow in and settle during hardening, improving adhesion to the base. The top coat layer is formed extremely thin, enhancing gloss and transparency and eliminating the need for a polishing process.

Description

[Technical Field]

[0001] This invention relates to tableware having a resin layer in which dried plant material (especially pressed flowers) is enclosed, and relates to a structure that combines multiple resin layers with a vessel-shaped base suitable for food use. More specifically, the present invention relates to tableware that combines aesthetic design with practicality by incorporating a groove structure to prevent interfacial peeling between the resin and the vessel-shaped base, and a multi-layer structure to aesthetically preserve the enclosed plants. [Background technology]

[0002] Many decorative items and miscellaneous goods have been proposed in which dried plant materials are encapsulated in transparent resin, and structures that emphasize visual aesthetics have been adopted (see Patent Document 1). In recent years, these technologies have been applied to food-related products, and some coasters and plates made from resin have been put to practical use. However, resin layers containing plant materials still have problems such as the inclusion of air bubbles, shrinkage during hardening, and interfacial peeling with the base, and currently there are not enough tableware proposals with specific structural solutions to these problems.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 56-155800 Summary of the Invention [Problem to be solved by the invention]

[0004] Conventionally, tableware made by encasing dried plants in resin has faced issues such as the deterioration of aesthetics due to air bubbles generated during the encasing process, and the risk of interfacial peeling between the resin and the vessel-shaped base due to shrinkage as the resin layer hardens. To address this risk of peeling, a molding method that does not use a vessel-shaped base but instead pours resin directly into a silicon mold is increasingly being adopted. However, this method requires a dedicated silicon mold for production, and the size and shape of the product depend on the mold, which limits the range of production and freedom of expression. Furthermore, although structures utilizing vessel-shaped substrates can be combined with existing tableware and materials, and have advantages in terms of mass production and applicability, their use has not progressed sufficiently due to insufficient measures to prevent structural peeling and air bubbles. [Means for solving the problem]

[0004] The present invention relates to a multi-layered resin tableware containing dried plant material, and solves the above-mentioned problems by providing the following structural features. That is, a plurality of resin layers are laminated in order on the inner surface of the vessel-shaped base, and dried plant material is enclosed in the middle layer of the plurality of resin layers. The multiple resin layers are made of a curing epoxy resin that complies with the Food Sanitation Act's Positive List System and consist of four layers: a base layer, a flower arrangement layer, an intermediate layer, and a top coat layer. The inner surface of the vessel-shaped base is provided with recesses that allow the resin to flow in. The resin hardens within the recesses, preventing interfacial peeling and increasing adhesive strength. The recesses are formed so that they intersect the direction in which the multiple resin layers peel from the vessel-shaped base, thereby more effectively preventing peeling of the resin layers. Furthermore, after the middle layer of resin is injected, the entire vessel-shaped base is subjected to a degassing process (decompression process) to remove any air bubbles remaining within or around the plant, which prevents air bubbles from getting mixed in and maintains the plant's aesthetic appearance. Furthermore, the top coat layer is formed extremely thin and is designed to enhance the sense of unity with the lower layer both visually and structurally, resulting in a configuration that achieves both surface smoothness and designability. [Effects of the Invention]

[0005] According to this invention, the following effects can be obtained: 1. By using highly transparent epoxy resin for the flower arrangement layer, middle layer, and top coat layer, and enclosing dried plant material such as pressed flowers in the middle layer, it is possible to create tableware with a three-dimensional and luxurious appearance. 2. By performing a decompression and degassing process after injecting resin into the intermediate layer, air bubbles remaining inside and around the pressed flower can be effectively removed, and the occurrence of unevenness and crater-like defects on the resin surface can be suppressed. 3. By forming the top coat layer extremely thin, less than 1 mm, it is possible to obtain a sufficient glossiness without the need for a polishing process, which contributes to simplifying the work process. 4. The groove structure created by the recesses on the inner surface of the vessel-shaped base allows the resin to flow into the grooves, harden, and adhere firmly, preventing interfacial peeling with the vessel-shaped base for a long period of time. 5. By using materials that comply with the positive list system under the Food Sanitation Act, the tableware can be provided as safe for use in food contact applications.

[0007] The tableware of this invention is formed by sequentially laminating multiple resin layers on the inner surface of a vessel-shaped base. First, shallow groove-like recesses are machined into the inner surface of the vessel-shaped base to enhance adhesion with the resin, and the resin flows into these recesses and hardens, creating a structure that prevents interfacial peeling. A base layer, a flower arrangement layer, an intermediate layer, and a top coat layer are laminated in this order within the substrate. Dried plant material (pressed flowers) is placed in the flower arrangement layer during formation and is sealed in by the intermediate layer. In addition, when forming the intermediate layer, it is recommended to perform a reduced pressure degassing process (under a negative pressure of -0.1 MPa or more), which removes air bubbles and microbubbles remaining inside and around the plant, improving the appearance quality. Furthermore, the top coat layer is formed to an extremely thin thickness of less than 1 millimeter, and is structured to achieve a sense of unity with the lower layer and a glossy surface. When injecting the resin into the intermediate layer, the vessel-shaped base is rotated while tilting, so that the resin spreads evenly along the inner wall, enhancing adhesion. [Example]

[0008] An example of tableware according to the present invention is shown below. In this example, a wooden vessel-shaped base measuring approximately 15 cm in length and width and 3 cm in depth was used, and a recess measuring approximately 3 mm in depth and 3 mm in width was formed on the inner surface of the base. The recess allows the resin to penetrate into the interior, improving adhesion to the base. The dried plant material used was pressed Allium sativum flowers that had been pre-colored and treated to fix the color. The resin used was a resin that complies with the positive list system of the Food Sanitation Act (enforced June 1, 2025), and multiple resin layers were formed with the following composition. · Base layer: This is the first layer formed on the bottom of the vessel-shaped base, and is composed of a certain thickness of colored or transparent resin. Flower arrangement layer: The second layer is formed on the base layer and is a resin layer for arranging dried plant materials. - Middle layer: This is the third layer that seals in the plant material. After the resin is injected, it is subjected to a degassing process under a negative pressure of -0.1 MPa or more, which effectively removes air bubbles from within and around the plant. Top coat layer: An extremely thin resin layer formed on the top layer, providing both gloss and surface protection. The finished tableware had high transparency and visibility, and showed an appearance in which the color and three-dimensionality of the pressed flowers were clearly preserved. It also had excellent adhesion to the base and washing resistance, confirming that the structure is suitable for everyday use. Supplementary explanation of the drawings Figure 1 is a three-dimensional perspective view of a vessel-shaped base of tableware with multiple resin layers in which pressed flowers are encapsulated according to the present invention. The vessel-shaped base (1) is made of wood, glass, ceramic, or resin material, and has steps or grooves formed on its inner peripheral surface. The inner surface of the vessel-shaped base is constructed by laminating a base layer, a flower arrangement layer, an intermediate layer, and a top coat layer in that order from the bottom up, with dried plant material (pressed flowers, etc.) enclosed in the intermediate layer. Such a multi-layer structure is configured to provide a plant-enclosing structure with excellent visibility. FIG. 2 is another perspective three-dimensional view showing the vessel-shaped base in which the dried plant material is enclosed. Inside the vessel-shaped base, multiple resin layers are laminated, and dried plant material is enclosed in the middle layer. The dried plant material is arranged to be held stably in place and is structured to prevent the plant material from floating within the layer. This structure uses a layered construction that allows the plant material to be clearly visible. FIG. 3 is a cross-sectional view of multiple resin layers formed inside a vessel-shaped substrate. On the inner surface of the vessel-shaped base (1), a base resin layer (2), a flower arrangement layer (3), an intermediate layer (4), and a top coat layer (5) are laminated in this order from the bottom up. The intermediate layer (4) contains dried plant material (6), and after the layer is formed, it is subjected to a degassing process under a negative pressure of -0.1 MPa or more, thereby removing air bubbles within the layer. The top coat layer (5) is a structure formed of an extremely thin layer of less than 1 mm, and is designed to ensure the smoothness and transparency of the upper layer surface. FIG. 4 is a cross-sectional view showing the recessed structure formed on the inner surface of the vessel-shaped base according to the present invention, and an enlarged view showing the details of the groove is also shown on the right side of the figure. The vessel-shaped base (1) is made of wood, glass, ceramic, or the like, and has a recess (7) formed along the inner periphery at the joint between the bottom surface and the rising portion. This recess (7) is designed to mechanically interlock with the vessel-shaped base as the resin flows into it and hardens when it is injected, and functions as an adhesion-reinforcing structure to prevent the resin layer from lifting or interfacial peeling. By providing such a structure with recesses, it is possible to improve the adhesion and adhesive strength between the base and the resin layer. [Explanation of symbols]
