DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the method for producing a three-dimensional decorative molded product with a printed pattern according to the present invention will be described below with reference to the accompanying drawings. As the fluid filler, chocolate confectionery, ice confectionery, jelly confectionery, butter,
In order to obtain foods such as cheese, and daily necessities such as eraser, soap, wax, gypsum, concrete, etc., there are various types of products that can be solidified by cooling, heating, etc. to solids by cooling or heating. According to the production method, any filler can be produced in the same manner, so in the present embodiment, as a typical filler, only the case of a fluid chocolate material for obtaining chocolate confectionery will be described and described. The case of the filler is omitted.

First, the elastic pad 5 used in this embodiment will be described. As shown in FIG. 3, the elastic pad 5 is used for supporting the elastic pad 5 to be inserted into an elastic mold 1 described later. It comprises a rod-shaped grip 5c and four pad surfaces 5b connected directly from the grip 5c or integrally via a support 5d. Each pad surface 5b has a window of a house,
Ink 5a of a printing pattern which becomes snow on the door and the roof is applied in advance.

An elastic forming die 1 having a bag shape is attached to a flat plate 3 as an elastic forming die mounting frame of an automatic continuous chocolate confectionery forming device (not shown) so that its opening 2 faces upward. Put into the decompression chamber 4 from the opposite opening side,
By decompressing and expanding the outer surface 1b of the elastic mold 1 in the direction of the arrow in the figure (see FIG. 1A), the inner surface 1a of the elastic mold 1 is slightly expanded. The elastic pad 5 is inserted into the expanded elastic mold 1. Then, by moving the decompression chamber 4 downward, or by weakening or stopping the decompression suction of the decompression chamber 4, the expanded elastic mold 1 is returned to the original shape, and the inner surface 1a is provided with an elastic pad. 5 is brought into contact with the pad surface 5b to transfer the ink 5a of the print pattern 6a (see FIG. 1B). Then, the pressure is again reduced by the decompression chamber 4 to expand the elastic mold 1, and after extracting the elastic pad 5, a predetermined amount of a fluid chocolate material 6 b having a temperature of about 26 to 32 ° C. is filled. After the bubbles of the chocolate material 6b are diffused by vibrating with a vibrator (not shown) attached to a lower part of a conveyor (not shown) for transferring the mold 1, a solidifying device, for example, about 4 to 7 ° C
Is transferred by a conveyor or the like (not shown) to a cooling tunnel (not shown) or the like kept at a constant temperature, and is cooled and solidified for about 10 minutes. Then, the elastic molding die 1 is put into a mold-removing device, for example, a decompression chamber 4 'of a decompression device, and the outer surface 1b of the elastic molding die 1 is decompressed and expanded, and the decompression device containing the elastic molding die is turned over. The chocolate material 6b is extruded by a rod-shaped pushing member 4'a provided as an auxiliary tool of the decompression chamber 4 ', which can press the chocolate material 6b therein without damaging it.
b is extracted (see FIG. 1 (c)), and a house-shaped three-dimensional decorative chocolate product 6 having a snow print pattern 6a on the window, door and roof made of the ink 5a is manufactured. (See FIG. 2). Here, the elastic molding die is expanded by decompressing and expanding the outer surface of the elastic molding die using a decompression chamber or the like, and the elastic pad is inserted.
