Description

The present invention relates to shapes and methods for producing shapes.

Conventionally, for example, the facial expression of a figure (eyes, eyelashes, etc.) is a very important part in determining the value of the figure as well as influencing the facial expression of the figure. For example, Patent Document 1 describes a method for manufacturing an eyeball for a doll, in which an abutting body such as an elastic silicon resin is pressed against a coating film that imitates the black eye of the eyeball by printing, and the adhered coating film is applied to the eyeball. The technique of transferring to a spherical surface imitating the above is described. By doing so, the black eye pattern formed by printing can be formed on the ocular spherical surface by the transfer of the coating film, and the black eye can be expressed with high accuracy.

Japanese Unexamined Patent Publication No. 2012-24382

However, when trying to express the eye by printing, there is a risk that the eye will be displaced with respect to the spherical surface of the eye. In a product such as the face of a figure, where the position of the face expression member becomes strange even a little, the eyeball with the misaligned eye position may impair the value of the product.

Also, in the case of a plastic model figure that lets the user perform part of the assembly, the eyes and face of the figure have traditionally been expressed with stickers. However, it may take a long time for the user to apply the sticker, or the seal may be misaligned. Therefore, it is difficult for the user to apply the sticker in a form that does not cause discomfort, and it is difficult to obtain a satisfactory finished product.
