JPH02140185A - Manufacture of vinyl toy including air - Google Patents

Abstract

PURPOSE:To easily manufacture a vinyl toy including air by forming a expanding part in a pair of external mounting bodies, providing an air cap in one external mounting body, housing an object to be housed into the internal part of both expanding parts, welding the overlapped external edges of the expanding parts and removing the unnecessary part of the external edge. CONSTITUTION:A pair of external mounting bodies 1 and 2 having expanding parts 1a and 2a in an almost central part are formed and a blowing-in port 6 of the air is provided in the expanding part 2a of one external mounting body 2. Then, an air cap 7 is mounted to the blowing-in port 6. The external mounting body 2 is loaded on a welding stand 8 and the upper external mounting body 1 is overlapped. Then, the both bodies are made mutually relative with the respective expanding parts 1a and 2a in an outside and external edges 10 and 20 are overlapped. At such a time, since a continuous space part 3 is formed in the internal part of the expanding parts 1a and 2a, an object to be housed is housed into the said space part 3. The overlapped external edges 10 and 20 are pressed flatly by a welder metal mold 9 from an upper direction and welded. After that, the unnecessary parts of the external edges 10 and 20 are separated and removed. The air blows from the blowing-in port 6 into the space part 3 and the air cap 7 is closed. Then, a whole shape is arranged and a product is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method of manufacturing an air-filled vinyl toy with a toy or the like stored therein.

(Prior art) Generally, when manufacturing pneumatic vinyl toys from sheet materials such as soft vinyl chloride, objects to be stored are simply placed between two upper and lower vinyl sheets, and these vinyl sheets are flat-pressed and welded using a welter. This is particularly true when the object to be stored is large, as the deformation of both of the vinyl sheets themselves becomes large, making flat pressing almost impossible. For this reason, conventionally, as shown in FIG. 1(a), a transparent vinyl cylindrical body 30 called a gusset is interposed between two vinyl sheets, and the interior of the cylindrical body 30 is covered. Storage items 5
In addition, as shown in FIG. There is one in which the edges of 33, 34, 35, etc. are successively welded to form a beach ball shape. However, all of these manufacturing methods for pneumatic vinyl toys have the disadvantage of being difficult to process and increasing costs.

(Object of the Invention) An object of the present invention is to solve the above-mentioned drawbacks and to propose a method for manufacturing an air-filled vinyl toy that is particularly easy to process.

(Means for achieving the object) In order to achieve the above object, the method for manufacturing an air-filled vinyl toy according to the present invention is characterized by comprising the following steps.

(a) Forming a bulge in each of a pair of exterior bodies made of a synthetic resin sheet, and providing an air plug in one of the two exterior bodies.

(b) Both the above-mentioned exterior bodies are overlapped with each other with each bulge facing outward, and objects to be stored such as dolls and toys are stored inside both bulges.

(c) Welding the overlapping outer edges of the bulging portions of both of the above-mentioned exterior bodies.

(d) Separating and removing unnecessary portions on the outside of the outer edge.

(Example) The method of the present invention will be explained below with reference to the drawings.

In FIG. 2, reference numeral A indicates a completed pneumatic vinyl toy produced according to the present invention.

Next, a method for manufacturing this pneumatic vinyl toy A will be described.

First, as shown in FIG. 3, a pair of transparent or translucent exterior bodies 1.
form 2. 5 is an object to be stored, which will be described later.

The pair of exterior bodies 1 and 2 are each made of vinyl chloride, and are usually made of sheet material with a thickness of about 0.4 mm. The bulging portions 1a and 2a can be easily obtained by vacuum molding a vinyl sheet material. An air inlet 6 is provided in the bulging portion 2a of one of the exterior bodies 2, and an air plug 7 is attached to the inlet 6.

Note that the shape of the bulging portions 1a and 2a may be a star shape, or a stacked shape such as a circle or a rectangle.

Next, as shown in FIGS. 4 and 5, the outer body 2 was placed on a welding table 8 in which a hole 8a was provided for a bulge part receiver having a predetermined shape corresponding to the outer shape of the bulge part 2a. Afterwards, the upper exterior body 1 is placed on top. Each bulge part la, 2a is made to face each other with the outside,
Polymerize the outer edge 10.20. At this time, the bulging portion 1a,
Since a continuous space 3 is formed inside 2a, the object 5 to be stored is stored in the space 3. The object to be stored 5 may be anything, such as a doll, an animal or plant toy, a vehicle toy, etc., but it should be of a size that can be stored in the space 3 formed by the superposition of the pair of exterior bodies 1.2. A holding member 4 such as a vinyl string or an elongated plate is attached to the stored item 5.

A portion of the holding member 4 is made to protrude from the space 3.

Furthermore, the superposed outer edges 10.2 of the bulges 1a, 2a
0 from above with a welder die 9 to weld the end edges 1O120 of the bulges 1a and 2a of both the upper and lower exterior bodies 1.2.

Finally, unnecessary portions on the outside of the outer edge 10.20 are separated and removed.

Air is blown into the space 3 from the air inlet 6, and the air plug 7 is installed to adjust the overall shape to obtain the product shown in FIG. 2. A portion of the holding member 4 protrudes outside the space 3. The holding member 4 holds the stored object 5 at a fixed position within the space 3.

(Effects of the Invention) As described above, since the bulges 1a and 2a are formed in advance on the exterior bodies 1.2 made of a pair of vinyl sheets and then welded, the stored items 5 are transferred to both exterior bodies 1.2 during welding. The overlapping portions of the outer edge portions 10 and 20 of the bulging portions 1a and 2a, which become welded portions when stored in . Very easy to manufacture.
