Description

[Technical field]

[0001] The present invention relates to a three-dimensional sticker toy, and more particularly to a transparent three-dimensional sticker toy of animals, characters, etc. [Background technology]

[0002] There are known toys that have a three-dimensional shape by inflating a hollow plastic bag, instead of flat toys such as animals. For example, Patent Document 1 provides a three-dimensional toy such as an animal, which is made of a thermoplastic plastic sheet and has an air inlet that is filled with air through the air inlet, and then sealed with the air inlet welded.

[0003] However, the above-mentioned toys made of plastic sheets inflated with air cannot maintain their three-dimensional shape for a long period of time because the plastic sheets tend to tear or the air tends to leak out. [Prior art documents] [Patent documents]

[0012] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. It goes without saying that the present invention is not limited to the following examples, and can be modified as desired without departing from the spirit of the present invention. In addition, the same or corresponding elements are given the same reference numerals, and duplicated explanations are omitted. Each figure is shown in a schematic manner to allow the invention to be understood, and some parts have exaggerated sizes, angles, thicknesses, etc. Figure 1 is drawn with mutually orthogonal XYZ axes.

[0013] <First Example> FIG. 1(A) is a front view showing a three-dimensional sticker toy 10 according to a first embodiment of the present invention. In the present invention, the three-dimensional sticker toy 10 is an animal character, but it may be another animal or plant or a cartoon character. The capsule 12 is preferably transparent. Here, transparency means that visible light from the back surface 16B (see FIG. 1(B)) of the flat sheet 16, which is the back surface of the three-dimensional sticker toy 10, can be seen from the front of the three-dimensional sticker toy 10. Even if it is generally called translucent, it is defined as transparent if visible light from the back surface 16B can be seen from the front of the three-dimensional sticker toy 10.

[0014] Fig. 1(B) is a cross-sectional view showing the AA cross section of Fig. 1(A). The capsule 12 is made of a thin sheet, which is heated and then vacuum-molded (vacuum processed) to form a capsule having a three-dimensional shape with a concave back surface 12B. The capsule 12 is made of a first resin, which can be a thermoplastic resin such as rigid PVC (polyvinyl chloride), PET (polyethylene terephthalate), or PMMA (acrylic).

[0015] As shown in FIG. 1(B), the capsule 12 has a front surface 12A and a back surface 12B, and the center is three-dimensionally bulged by vacuum molding, with a peripheral portion 12P surrounding it. The entire peripheral portion 12P is formed on the same plane in the Z-axis direction. The recessed area of ​​the back surface 12B is filled with a core 14 made of a second resin by vacuum molding. The second resin is appropriately measured and injected under temperature control so that the core 14 is formed up to the peripheral portion 12P. In other words, the bottom surface 14B of the core 14 is on the same plane as the peripheral portion 12P.

[0016] The second resin is, for example, a transparent epoxy resin. The epoxy resin is a two-liquid mixture of liquid A and liquid B, where liquid A is epoxy resin and liquid B is epoxy resin with a hardening function. For example, the ratio of liquid A: liquid B is 3:1. Of course, the epoxy resin may be liquid A epoxy resin and liquid B hardener in a ratio of 9:1. Transparent phenolic resin may be used instead of transparent epoxy resin. Epoxy resin or phenolic resin is a thermosetting resin. These thermosetting resins are not made of phthalic acid, which is a harmful component, and have the advantage of being less likely to crack or whiten after drying.

[0017] The second resin may be colored and transparent (semi-transparent). Also, fine reflective materials such as thin wires, strips, disks, and doughnut-shaped plates that reflect light may be mixed into the transparent epoxy resin. Specifically, strip-shaped glitter or doughnut-shaped sequins may be mixed into the second resin. This results in a three-dimensional sticker toy 10 that shines in the light.

[0018] A flat sheet 16 is attached so as to cover the bottom surface of the core 14. The sheet 16 has a base material 16p, an adhesive layer 16q, and a separator 16r. In order to facilitate welding, the base material 16p of the sheet 16 is preferably made of the same thermoplastic resin as the first resin. For example, the base material 16p is made of a thermoplastic resin such as PVC (polyvinyl chloride), PET (polyethylene terephthalate), or PMMA (acrylic). The peripheral portion 12P is formed on the same plane as the bottom surface of the core 14, so that the peripheral portion 16P of the sheet 16 contacts the peripheral portion 12P of the capsule 12. The peripheral portion 16P of the sheet 16 is welded to the peripheral portion 12P by welding (high frequency welding). Although not necessarily required, the surface of the base material 16p may have an adhesive layer so as to be firmly attached to the bottom surface 14B of the core 14.

[0019] The three-dimensional sticker toy 10 is attached to a table, a bag, or other objects. For this reason, an adhesive layer 16q is provided on the underside (-Z axis direction) of the base material 16p. A separator 16r is provided to cover the adhesive layer 16q. The separator 16r is preferably made of a material different from that of the base material 16p, such as paper, polyethylene, or PET.

[0020] As described above, the three-dimensional sticker toy 10 has a three-dimensional shape, the entire surface of which is covered with the capsule 12 and the flat sheet 16, and the inside of which is filled with the core 14. Children can play with the relatively low-priced transparent three-dimensional sticker toy 10.

[0021] Furthermore, a pattern such as a character's nose or eyes may be printed or foil stamped on the front surface 12A or back surface 12B of the capsule 12. In particular, when a pattern is printed on the front surface 12A or back surface 12B of the capsule 12, the pattern such as the character's nose or eyes can be seen according to the three-dimensional shape of the capsule 12's nose or eyes when viewed from the front of the three-dimensional sticker toy 10.

[0022] Instead of printing on the front surface 12A or back surface 12B of the capsule 12, a pattern such as a character's nose or eyes may be printed or foil stamped on the front surface 16A or back surface 16B of the base material 16p of the flat sheet 16. Glitter may also be printed so that the character shines in the light. Printing may also be performed on both the front surface 12A or back surface 12B of the capsule 12 and the front surface 16A or back surface 16B of the base material 16p of the flat sheet 16. This results in a three-dimensional sticker toy 10 that allows the viewer to feel a sense of perspective via the core 14 (second resin).

[0023] <Second Example> Fig. 2(A) is a front view of a three-dimensional sticker toy 10 according to a second embodiment of the present invention. In the three-dimensional sticker toy 10, a rhinestone 31 or 33 is attached to a surface 12A of the capsule 12 of the three-dimensional sticker toy 10 of the first embodiment by adhesive or the like. Fig. 2(B) is a cross-sectional view showing the AA cross section of Fig. 2(A), showing that a rhinestone 31 is attached.

[0024] Rhinestones are decorative parts that are made by faceting the surface of crystal, glass, acrylic resin, etc. to resemble a diamond. Rhinestones come in shapes such as diamond, dome cut, heart, star, oval, square, and triangle. In the second embodiment, star-shaped rhinestones are attached to the inflated and non-inflated parts of the capsule 12. By attaching the rhinestones, the sticker toy 10 can be made to have a luxurious feel.

[0025] Although not shown as an example, the capsule 12 may have a laminate coating applied to the surface 12A. The purpose of the laminate coating is to protect the pattern printed on the surface 12A of the capsule 12 from water, dust, scratches, fading, etc. PP (polypropylene) is generally used as the form for the laminate coating.

[0026] <Manufacturing method for 3D sticker toys> FIG. 3 is a flow chart showing the assembly process of the three-dimensional sticker toy of the present invention. In step S31, a pattern is printed on a thin sheet of the first resin. The same is true for the three-dimensional sticker toy 10 according to the second embodiment. Since the three-dimensional sticker toy 10 does not need to have a pattern, step S31 does not need to be performed.

[0027] In step S32, a thin sheet of the first resin is vacuum molded to form capsules 12. Specifically, a mold (not shown) on which one or more characters or the like are engraved three-dimensionally is attached to a vacuum molding device, and a sheet of the first resin is set on the mold. Then, the first resin is heated with a heater or the like to a temperature at which it becomes soft, for example, about 250°C for hard PVC, until it becomes soft, and then vacuum suction is applied through several small holes opened in the mold to form a plurality of capsules 12. The sheet of the first resin is then cooled to room temperature.

[0028] In step S33, the capsules 12 molded in the first resin sheet are individually cut and separated. Note that step S33 may not be performed and the capsules may not be individually cut. Depending on the size of the capsules 12, only one capsule may be molded in one first resin sheet. In this case, step S33 may not be performed.

[0029] In step S34, the second resin is injected into the recessed area of ​​the back surface 12B of the capsule 12 by vacuum molding. If the capsules are not cut individually, the second resin is injected into the multiple recessed areas. In order to prevent the capsules 12 made of the first resin from being deformed by heat, the second resin is preferably a two-part thermosetting resin mixture type, and for example, the second resin at 40°C is injected into the recessed area of ​​the capsule. The injection amount of the second resin is measured in advance, and by injecting the injection amount into the recessed area, the bottom surface 14B of the core 14 is flush with the peripheral portion 12P of the capsule 12, as shown in FIG. 1(B).

[0030] In step S35, the flat sheet 16 is attached to the capsule 12. More specifically, the flat sheet 16 is arranged so as to cover the capsule 12 and the core 14. Then, the peripheral portion 16P of the flat sheet 16 is fused to the peripheral portion 12P of the capsule 12 by welding. In steps S31 to S35, the three-dimensional sticker toy 10 is completed.

[0031] When rhinestones are attached to the capsule 12 as in the second embodiment, the rhinestones are attached with adhesive or the like in step S36. By adding step S36, the three-dimensional sticker toy 10 shown in FIG. 2 is completed.

[0032] As described above, the three-dimensional sticker toy 10 of the present invention can be played with by users as a three-dimensional sticker toy that can maintain its three-dimensional shape for a long period of time. In addition, the three-dimensional sticker toy 10 of the present invention can be sold as a three-dimensional sticker toy with reduced labor and manufacturing costs. [Explanation of symbols]
