Abstract

This invention relates to a method of producing an inflatable toy or balloon by use of a plastic film such as a polyethylene film, and more particularly to a method of providing easily protuberances. A pair of protuberances such as the feet of an animal and the half of the belly portion between them are shaped at the W-shaped gazette-folded portion of a composite film having an easily fusible plastic such as polyethylene on one of its surfaces, and are fused from above and below by a heat sealer or the like in the same way as in a conventional production method. When inflated, the body of this toy consists of three surfaces. One of the surfaces is the belly portion which is sufficiently thick, and inflated feet are provided to both sides of the belly portion. Accordingly, the toy can stand up stably. Particularly in the composite film for a balloon, this method makes it for the first time possible to produce a three-dimensional protuberance, and provides a novel effect on conventional balloons which have been merely round because they are merely formed by bonding the surface and back members and monotonous.

Inflatable toys or wind | & manufacturing method Technical Field ''

It relates to the production of inflatable toys and balloons made of plastic film such as polyethylene, and particularly to the production of simple projections such as animal limbs and car wheels. Background art

Inflatable toys and balloons made of plastic film such as polyethylene are not covered with a high-frequency machine or the like along the sewn line of a pattern like a vinyl sheet. It was manufactured by stacking two materials, pressing a heat sealer on top of them, welding and cutting out.

Even when inflated toys and balloons made by such a method were inflated with air, they had only a three-dimensional appearance, like a thick sea bream, like a sea bream bream. In addition, since projections such as three-dimensional limbs could not be made, they did not stand even if they tried to stand.

In particular, balloons that can hold hydrogen or hemi-float can be processed freely, but cannot be made of heavy and easy-to-lease vinyl film other than rubber from old days. Since there was only an ultra-thin composite film, etc., there were only spherical or deformed objects that consisted only of the front and rear sheets, and three-dimensional animals could not be made, and there were few changes. Disclosure of the invention

Inflatable toys and balloons of animals, vehicles, etc., composite films, folded in V-shape so that polyethylene etc. face up, face to face with another simple substance or composite film polyethylene etc. Between A pair of protrusions such as legs, wheels of animals, vehicles, etc., and a half of the distance between them, such as the abdomen and the bottom, are shaped to form a quadruple film part. The composite film is folded into a V shape or a V shape based on one straight line on each side of three or more composite films, or the reference lines are overlapped so that polyethylene etc. face each other in a plane or all With one or a smaller number of films so that the lines around the animals, vehicles, etc. are completely closed on each of the overlapping surfaces, and use a heat sealer, etc., to cover the entire circumference l. It was made by welding hermetically.

When inflated, the body of the toy can be described in cross-section, with one V-shape being composed of three sides, like a triangular inflation, two with four sides, one of which is the abdomen, bottom, etc. The ridgeline has a pair of protrusions, that is, limbs on both sides of the abdomen and wheels etc. on both sides of the bottom. On the other hand, two faces that come out of the reference line and face each other In the method of sealing, it was possible to have projections having different shapes. BRIEF DESCRIPTION OF THE FIGURES

1 and 2 are perspective views showing another example of the manufacturing method of the present invention, and FIGS. 3 to 5 are perspective views of the completed inflatable toy and balloon. BEST MODE FOR CARRYING OUT THE INVENTION

Fig. 1 is a perspective view showing an example of the production method of the present invention, and Fig. 3 is a perspective view of a horse produced by cutting out and inflating the horse. Simple or composite film

A composite film consisting of polyethylene and a film with a higher welding temperature such as nylon, polyester, or non-weld paper. In this way, the two folded films 3 are sandwiched in a V-shape, and inflated from above to form a toy horse 4, but at this time, a quadruple The forefoot 6, the hindfoot 7, and the abdomen 8 of the horse 4 are formed on the part 5 of the film. Then, as in the conventional manufacturing method, the entire periphery of the inflated toy is welded in an airtight manner from above and below the film, or from one side using a heat sealer, etc. and cut out simultaneously or back and forth, and baking soda and citric acid: Such a mechanism for generating carbon dioxide gas is sealed and completed as shown in Fig. 3. .

Fig. 2 is a perspective view showing another example of the manufacturing method of the present invention. Similarly, one composite film is formed by laminating polyethylene and nylon, polyester, non-welded paper, etc., which have a higher welding temperature than that of polyethylene. The film 1'2 'and the flat film 3', which are folded into a shape based on the straight line of the above, are overlapped with their reference lines so that the polyethylene faces each other, and inflated on each of the overlapping surfaces, and the toy horse Shape four. The head and torso are not shown in film 1 no 2 ', the forefoot 6, hind foot 7 and abdomen 8 on one side in film 1' 3 ', and not shown in this figure in film 2' 3 '. The opposite forefoot 6 ', hindfoot 7' and abdomen 8 'are each shaped so that the lines around them are completely closed. Then, inflate with a heat sealer or the like from the top or bottom of each of the overlapping surfaces, and airtightly weld the entire periphery of the toy, cut out simultaneously or back and forth, and seal the mechanism that generates carbon dioxide gas such as baking soda and citrate. Then, complete as shown in Fig. 3.

According to the invention of Φ, not only the forefoot 6, 6 ′ and the hindfoot 7, 7 ′ of the horse 4 in FIG. 3 but also the vehicle 9 in FIG. The paired projections such as front wheel 10 and 10 ', rear wheel 11 and 1 1', and crocodile 13 upper jaw 14 lower jaw 15 as shown in Fig. 5 And can be made easily. Furthermore, according to the manufacturing method shown in Fig. 2, the shape of the protrusion of the heat seal can be made different from that of the heat seal, so the horse can run, for example, by changing the shape of the foot from left to right. You can do it.

Further, the distance indicated by the arrow of the abdomen 8 in FIGS. By taking minutes 5 or from the reference line, you can create a separation between the abdomen of the horse, ie, the forefoot 6, 6 'or the hindfoot 7, T. The distance shown by this arrow is one half of the separation distance, and the same

_{5 The} distance between the front wheels 10 and 10 'and the rear wheels 11 and 1Γ of the vehicle 9 in Fig. 4 is the distance between the rear wheels 11 and 1Γ, that is, the bottom 12 is also very effective for stably standing and giving a solid feeling. . In the examples, a composite of polyethylene and nylon, polyester, or the like was used. However, in the present invention, not only this but also polypropylene and ethylene vinyl acetate instead of polyethylene.

, ο Polymer, etc., Nylon, Polycarbonate may be used for paper or metal film to be bonded to the outside, In other words, the inside polyethylene etc. sufficiently performs the welding function, and the outer film does not weld or does not weld Any combination having only a difference in welding temperature may be used.

Also, in the manufacturing method of Fig. 1 and Fig. 2, instead of three films,

₁₅ One or two composite films can be used for such bending, and in Fig. 1, two or more V-type composite films may be used. Four or more composite films may be stacked, and furthermore, a composite of the production method of FIG. 1 and the production method of FIG. 1 may be used. Also, instead of a mechanism that generates carbon dioxide gas, with an air inlet or air valve

_{A 20} inlet may be provided. In particular, for balloons that play with helium gas or the like and float in the air, it is necessary to provide a blowing port or a blowing port with an air valve, make the composite film of the material extremely thin and have gas barrier properties. is there. as Industrial Applicability

The body of a toy or balloon is composed of three sides, like a V-shaped cross section in a triangle, and two sides are four sides, and two sides are the abdomen, bottom, etc. It became much more three-dimensional than the ones that were made.

Furthermore, on both sides of its abdomen, bottom, etc., a pair of protrusions, ie, swollen limbs The wheels, etc. are attached in pairs, so they can stand up stably. In addition, if a shape with a deep cut like the crocodile α is formed in the present invention, not only the limbs, but also the open angle can be freely and at any angle

5 could also be fixed. -Light and gas-barrier composite films made of polyethylene, nylon, etc. can produce three-dimensional projections, giving a new effect to balloons that are spherical and have little change.

Moreover, in the same way as the conventional method of making inflated toys such as polyethylene

, ο Since it is simply welded from above and below with a heat sealer, etc., it can be said that this is a highly economical manufacturing method that does not change equipment and costs.
