Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing pneumatic vinyl toys.

Generally, when trying to manufacture an air-filled vinyl toy that stores objects such as dolls from vinyl chloride sheets, the objects are placed between two upper and lower vinyl sheets, and the objects are synthesized from the outside of the objects. If an attempt was made to weld the resin sheets by flat pressing using a welder, the welded portions of both vinyl sheets would be deformed, making flat pressing almost impossible. Therefore, conventionally, as shown in Figure 1a,
A transparent synthetic resin cylindrical body 30 called a gusset is interposed between two vinyl sheets 31 and 32,
As shown in FIG. Oval shaped vinyl sheet material 33,3
4, 35... are sequentially welded to form a beach ball shape, and the stored object 5 is placed inside the beach ball shape.
There are ways to store it. However, all of these pneumatic vinyl toys had the disadvantage of being difficult to process and high in cost.

The present invention solves the above drawbacks, is particularly easy to process,
The purpose of this paper is to propose a manufacturing method for pneumatic vinyl toys that can improve manufacturing efficiency.

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, symbol A is an example of an air-filled vinyl toy to be obtained by the present invention. The gist of the manufacturing method for this air-filled vinyl toy A is that first, a pair of vinyl chloride sheets a and b have bulges 1 and 1, respectively.
2 and providing an air plug 7 in one of the bulges 2, with the bulges 1 and 2 facing outside, the outer edges 10 and 20 of the bulges 1 and 2 are removed. polymerize,
The outer edge is welded by welding.

Next, each manufacturing process of the method for manufacturing the above-mentioned pneumatic vinyl toy will be explained in detail.

First, a pair of vinyl chloride sheets a and b are bulge-molded. At least one of the pair of sheet materials a and b is a transparent or translucent sheet material, and each is preferably a soft vinyl chloride sheet with a thickness of about 0.4 mm. A bulge 1, 2 having a star-shaped, circular, rectangular or other suitable outer shape approximately at the center of each of the sheet materials a, b.
form. Such bulges 1 and 2 can be easily formed by vacuum molding a vinyl chloride sheet. Since the thickness of the bulges 1 and 2 is approximately 0.4 mm, the outer shape of the bulges 1 and 2 is maintained constant. Note that, normally, the shapes of the outer edges 10 and 20 of both the bulges 1 and 2 are substantially the same.
An air inlet 6 is formed in one of the bulges 2a,
A plug 7 is attached to the blowing port 6.

Next, the vinyl sheets a and b are put together with these bulging parts 1 and 2 on the outside, and after storing the object 5 in the internal space 3, the outer edges 10 and 20 are overlapped,
Flat press welding using a welder. By overlapping the outer edges 10 and 20 with the pair of bulges 1 and 2 on the outside, a space 3 is formed in both the bulges 1 and 2. Therefore, the object to be stored 5 is stored in the space 3. Further, as described above, the outer edges 10 and 20 of both the bulges 1 and 2 are formed flush with each other, so that the outer edges 10 and 20 overlap without any gap.

The stored items 5 include dolls, animal and plant toys, vehicle toys, etc.
Any size is acceptable, but the size should be such that it can be accommodated in the space 3 formed by the pair of bulges 1 and 2 overlapping each other. A holding member 4 such as a vinyl string is attached to the stored item 5, and a portion of the holding member 4 protrudes outside the packaging space 3. This holding member 4
As a result, the stored item 5 is held at a fixed position within the packaging space 3, and the pneumatic vinyl toy A can be hung. Note that such a holding member does not necessarily need to be attached to the stored object 5 in advance.
A configuration may be adopted in which a part of the outer edges 10, 20 is made to protrude and a hole is formed in this protrusion for a string or the like to pass through.

In welding the overlapping outer edges 10 and 20, as shown in FIG. Place one on a welding table 8 provided with a. At this time, it is preferable to apply a suitable support member (not shown) to the lower surface of the bulge 2 to support it. The stored object 5 with the holding member 4 attached is stored in the bulge 2, and another vinyl sheet a is placed over it, and the bulge 2 of the lower vinyl sheet b and the upper vinyl sheet a The outer edges 10 and 20 are overlapped with each other by matching the bulge 1 of the outer edges 10 and 20. At this time, a part of the holding member 4 of the stored object 5 is
Let it protrude to the outside of 2. A welder die 9 is pressed flat from above the upper bulge 1 to weld the outer edges 10 and 20 of the upper and lower bulges 1 and 2. Finally, air is blown into the packaging space 3 from the air inlet 6, and the plug 7 is closed to adjust the overall shape.

In this way, since the pair of vinyl sheets a and b are bulge-molded in advance to form the bulges 1 and 2 and then welded, the objects 5 to be stored can be stored in both the bulges 1 and 2 during welding. In this state, the overlapping portions of the outer edges 10 and 20 of the bulging portions 1 and 2, which become welded portions, are flush with each other, and therefore flat pressing can be performed easily and reliably. On the other hand, conventional air-filled vinyl toys are made of thin vinyl sheet material with a thickness of about 0.2 mm, so they have poor rigidity and cannot be shaped even if the bulge part is molded as described above. However, the manufacturing method described above was unthinkable.

As explained in detail above, objects to be stored such as dolls and toys are stored inside a pair of vinyl chloride sheets with the bulges formed in advance facing outward, and the outer ends of both bulges are Since the edges are overlapped and welded, the overlapping part of the outer edge of the bulge, which becomes the welding part, is flush with the object being stored in both exterior bodies during welding, so it is pressed flat. It can be manufactured by welding, and the manufacturing efficiency of pneumatic vinyl toys can be greatly improved.
