Abstract

This invention relates to a seal using an adhesive gel and a method for manufacturing the same. Conventionally, with thick gel sheets, high-resolution printing is difficult due to the adhesiveness of the surface, and it is also difficult to maintain the function of preventing accidental ingestion with a bittering agent and the design after washing. This invention employs a configuration in which an adhesive gel sheet is cut into a desired shape, an image is formed on the surface with reduced adhesiveness, a bittering agent is applied, and a transparent protective layer is formed to continuously cover the surface and the sides of the gel sheet. This provides an adhesive gel seal that enables the formation of a high-resolution design and can maintain the image and bittering function while recovering its adhesive strength after washing.

Description

This invention relates to a seal using an adhesive gel and a method for manufacturing the same. Seals made from adhesive gel materials are used for decorative purposes due to their flexibility and repositionable properties. However, as described in Patent Document 2, there is a problem with low print adhesion due to the surface structure of the gel. Furthermore, to prevent accidental ingestion by infants, techniques for imparting bitter components are known, as shown in Patent Documents 1 and 3. According to Patent Document 1, coating with solvent-based paint is proposed to prevent the loss of bitter components through washing or wiping. However, protection including the sides of thick gel products, and the balance between restoring adhesive strength after washing and maintaining bitterness, have not been adequately considered. Especially with thick gel sheets, dirt adhesion due to the adhesiveness of the sides is significant, and there is a need for a technology that forms a continuous protective layer from the surface to the sides, maintaining high levels of safety and durability.

The embodiments of the present invention will be described in detail below with reference to the drawings (Figures 1 to 10). Figure 1 shows the overall process for manufacturing an adhesive gel seal 100 according to one embodiment of the present invention (see Figures 5 and 7). The adhesive gel seal 100 is a decorative or adhesive component primarily composed of an adhesive gel-like material. The overall layer structure of the adhesive gel seal 100 in this embodiment will be explained with reference to Figures 2 and 3. The adhesive gel seal 100 is constructed with a gel-based substrate 10 as its core. The gel core 10 is formed from a material that possesses flexibility and adhesive properties. The gel-based material 10 can be silicone-based gel, urethane-based gel, acrylic-based gel, etc. Silicone-based gels exhibit excellent heat resistance and chemical stability, resulting in minimal degradation even with long-term use. Urethane-based gels possess high shock absorption and moderate surface adhesion, providing a unique elastic feel. Acrylic gels have high transparency, which is advantageous for improving the visibility of the design (see Figure 6) described later. These gel materials are selected appropriately depending on the application and the desired texture. The gel-based material 10, due to its adhesive properties, can be repeatedly attached to and removed from smooth surfaces (see Figure 9). In this embodiment, the gel body 10 is formed to have a predetermined thickness (see Figure 4). The thickness of the gel body 10 is preferably set to 0.2 mm or more and 10 mm or less, and more preferably to 3 mm or more and 10 mm or less. By making the thickness 0.2 mm or more, it becomes easier to secure side surfaces 15 that connect the surface and bottom of the gel body 10, and it becomes easier to appropriately realize the structure of the present invention, in which the transparent protective layer 13 is continuously coated from the surface to the side surfaces 15. This makes it possible to suppress the exposure of stickiness on the side surfaces 15, suppress the adhesion of dirt, and maintain the design. Furthermore, compared to extremely thin film-like members, it is easier to maintain the desired shape 16 after cutting, and each process of surface treatment, printing, and protective layer formation can be carried out stably.
