Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a soft synthetic resin film balloon for children's magazines, toys and other beach equipment.

(Prior Art) Conventionally, soft synthetic resin film balloons between children's magazine appendixes, toys, and other beach equipment were produced by simply heat-sealing a balloon pattern on a simple two-layer soft synthetic resin film material. The main thing is that it is an ordinary front and back dihedral balloon, not a polyhedron. Therefore, for the production of a polyhedral balloon with two or more sides, each unit piece of the polyhedron formation cut in advance to the required number of faces is used. , They are joined by hand one after another. That is, in the case of a paper balloon, a required number of long and thin elliptical unit pieces are stuck together, or in the case of a rugby ball type balloon, four elongated elliptical unit pieces are stuck together, or If the material is a resin film, the above 4
It will be manufactured by sequentially heat-sealing the unit pieces, and in the case of other beach balls and animal toy balloons, it is also a sticker of unit pieces, toys such as goldfish type balloons and airships. In the case of balloons as well, a dihedral balloon with a printed pattern is usually used, but if it is to be a polyhedral stereoscopically realistic balloon, it is also a joint production of unit pieces, and accordingly, a unit piece suitable for it. Since the production of the cloud itself sometimes turns into a strange cloud shape of complicated shape, the production of the cloud-shaped unit piece is also very complicated, and the sequential sealing process requires very difficult and prudent skilled manual work. It becomes a high-cost product, is not suitable for cheap toy balloons such as magazine appendices, and the demand range is narrow.Furthermore, even if a costly high-cost polyhedron toy balloon is manufactured, the seal line will be radial. Collection to gather Base point, as the bulge of the balloon,
Since it is inevitably and physically the weakest part in the tensile strength due to the inside air, there is a risk of pinholes or rupture.

To prevent this danger, as is clear from paper balloons, it is necessary to attach a separate reinforcing piece to the base point of the seal line, and with a resin film material balloon, which is troublesome, the sealing of the reinforcing piece is extremely troublesome. Is. However, if this troublesome reinforcement piece is not attached, there is a drawback that pinholes and ruptures are likely to occur at the above-mentioned aggregate base points, so that pinholes and ruptures still occur in resin film materials. However, it is impossible to mass-produce inexpensive polyhedron-shaped toy balloons that ensure safety.

(Problems to be solved by the invention) The present invention eliminates the above-mentioned conventional drawbacks, simplifies the production and provision of various polyhedral balloons made of a soft synthetic resin film, and particularly, the automatic production by the mechanical force of a bag-making machine. Of the heat seal wire, which is the weakest against the tensile force due to the internal pressure in the polyhedral balloon, and the pin that is inevitably and physically generated. Preventing the danger of holes and ruptures without any additional reinforcement piece, it is possible to provide inexpensive toy balloons of this kind that are safe and have long-term usability and high commercial value. Is intended to spread.

(Means for Solving the Problem) A means for folding both ends or one end of a soft synthetic resin film balloon material such as polyethylene having a non-sealing outer surface into a V-shaped, W-shaped or bellows-shaped folded portion, With a balloon material, swell like a pouch at the intersection of the inner folding line of the material and the cutting line under the heat-sealing cut of the material in various desired balloon pattern shapes surrounding the center line of the material. It is a means for forming a heat-seal cut by connecting the small bulging portions from the cutting line.

Further, a means for connecting a single or a plurality of minute bulges to the small bulges, and an outer surface is a non-sealing surface.
Between both ends or one end of a stack of soft synthetic resin film,
The balloon material is used in which at least one or more separate folded pieces of the same material as the V-folded, W-folded or zippered folded film are sandwiched with the openings facing outward, and both ends or one end is folded. The above means.

(Function) When a soft synthetic resin film balloon material having both ends or one end folded is heat-sealed into a balloon pattern, the outer surface of the non-sealing surface is not heat-sealed, and only the inner surface which is the sealing surface is heat-sealed. Then, a balloon body was cut, and in this balloon body, the heat seal line became the dividing line of each surface, and since the folding surface became a continuous surface in addition to the two front and back surfaces, when inflated from the air valve opening, The bulge of the continuous surface instantly becomes a polyhedral balloon.

In the case of V-shaped folding at both ends, two surfaces increase due to the bulging of the upper and lower folding surfaces, and the front and back surfaces are combined to form a tetrahedral balloon. In the case of V-shaped folding with only one end, the folding part side By increasing the number of faces, it becomes a trihedral balloon, and the W-shaped and jar-shaped folds become polyhedral balloons in which the number of heat seal lines and the number of continuous faces are increased in proportion to the number of folds. Then, due to the bulge of the balloon body, the small bulge portion provided at the intersection of the inner fold line and the heat-sealing cut line of the balloon pattern figure bulges into a pouch according to the bulge of the balloon body. The strong tensile force due to the internal pressure that should be applied to the intersection is dispersed in the concave root of the small bulge that bulges like a pouch, and physically weakens. The risk of bursting is prevented.

(Embodiment) An embodiment of the present invention will be described with reference to the accompanying drawings.
The figure shows that the outer surface is a non-sealing surface (1), and both upper and lower ends or one end is folded into a V-shaped, W-shaped or jarred shape toward the lateral center line to form a folded portion (2). A soft synthetic resin film balloon material (3) such as a tube or a sheet-like sheet made of polyethylene or the like, which is folded at one end in FIGS. 1 and 3 (a), and in FIGS. 2 and 3 (b). -(D) is a material that is folded at both ends, and the folding type is V-fold in Fig. 3 (A) and (B), and W-fold in Fig. 3 (C).
FIG. 3 (d) shows a zigzag fold.

The present invention relates to the material (3) provided with the folded portion (2), and a balloon mode figure (4) surrounding the lateral center line, for example, an elliptical shape in FIG. 4, a fish figure in FIG. In a circle shape and other desired balloon shapes (not shown), an air valve opening (5) is formed with two lines at each location to form a heat seal cut (6), and an inner folding line () of the folding portion (2) ( At the intersection (8) where 7) and the cut line (6) intersect, a small bulge (9) that bulges like a nipple type, a tengu nose type, a hemispherical type or the like is connected from the cut line to heat seal. The balloon body (10) is cut out by cutting (6).

The non-sealing surface (1) on the outer surface of the material (3) is a heat-resistant media. Ink printing processing or non-sealing laminating processing is used.

The film used for the material (3) is mainly a tube, but it is also applicable to a two-sheet sheet shape (the tube is cut open into a sheet shape).

Further, the air valve provided in the balloon body (10) has a two-line heat seal cut (6) with an air valve opening (5) as shown in the figure.
In the case where a cylindrical valve is provided in addition to the above, the air valve opening (5) is provided with a well-known cylinder valve tool, or a part of the balloon body (10) is perforated and the hole is formed in the hole. A known tubular valve device may be attached by a known means.

Next, referring to FIGS. 4 to 7, in the case of a rugby ball type toy balloon as an example of a balloon mode of the present invention, the material (3) having V-shaped folds at both ends is connected to the intersection point (8) as described above. If a heat-sealing cut (6) with an elliptical shape provided with a small bulge portion (9) is immediately formed into a rugby ball type balloon body (10) that bulges into a tetrahedron. 1
Targeting the material (3) of V-fold on one end in FIGS. 3 (a) and 3 (b), an elongated ball-type balloon body having a rice ball-shaped cross section related to a trihedron is obtained. In addition, the hexahedral balloon is W-folded in Fig. 3 (C),
As for the hexahedron or more, each material of the double-sided folding shown in FIG. In addition, if one end is V-folded and the other end is W-folded, a pentahedral balloon is formed, and an odd or even desired number of polyhedrons can be obtained depending on the combination of folding shapes.

Further, in FIGS. 12 to 13, if a circular figure is cut on a V-folded material at one end, a three-sided spherical balloon is formed. In this case, small bulging portions (9) are formed at the intersection points (8) on both sides. ) Will be provided.

Then, as an example of a toy balloon for fish or animal figures other than balls, as shown in FIG. 8, if one end V-folded material is cut with a goldfish figure, the lower fold portion expands to the whole surface.
A plane three-dimensional goldfish balloon body is created, and in addition, various three-dimensional balloon bodies such as animals and airships are also created only by the heat seal cutting means of the mode. Next, in FIGS. 10 and 11, for the purpose of further weakening the tensile force with respect to the small bulging portion (9), a single or a plurality of minute bulging portions (11) (11) ′ ... This is the structure of the balloon bodies (10) connected in series.

FIG. 14 shows another embodiment of the film material (3),
It is a V-folded or W-folded or a double-folded folded film (2) between both ends or one end of a soft synthetic resin film (3) 'having two non-sealing surfaces (1) on each outer surface. 3) 'and the same piece of folding piece (12) (13) (14),
It is a material configuration in which at least one or more openings are sandwiched outward and both ends or one end is in the same state as folding.

From the above, the production of the balloon body (10) with the heat-sealable cut (6) for the material (3) described above does not cause the outer surface of the non-sealable surface (1) to be heat-sealed and has a sealable surface. Only the inner surface of the treatment is heat-sealed, and each folding part (2) expands to the left and right with the seal line as a boundary.
5) ′ and the balloon body (10) becomes a polyhedron,
A balloon body (1 with an elliptical shape surrounding the horizontal center line of the material (3)
If you cut (0), the polyhedral balloons (1) of rugby ball type or airship type (1) depending on the fold shape of the folding part (2) and the number of folds.
0) will be produced easily and immediately.

In addition, a toy balloon that has a multi-faceted three-dimensional shape such as a fish shape such as a goldfish and various animal shapes can be easily manufactured based on the folding shape and the number of folding of the folding part (2). Body (10)
Then, the intersection point (8) where the inner fold line (7) and the cut line (6) intersect is the weakest against the tensile force due to the balloon bulge,
The present invention is particularly
As described above, in order to reduce the tensile force at the intersection (8),
The danger prevention was solved by providing the intersection (8) with a small bulge (9) which is connected to the cutting line and bulges like a pouch.

It is because the pouch-shaped bulge of the small bulge portion (9) is formed at the boundary of the balloon main body (concave root a (micro bulge portion (11) (1
In 1) '..., the tensile force is physically dispersed and weakened in the a') portion, so that the above-mentioned risk prevention is surely guaranteed.

As described above, the production of the product of the present invention requires only the folding process of the material and the heat-sealing cutting means according to the balloon pattern (4) surrounding the lateral center line, so that automatic production by mechanical force using a conventional bag-making machine is possible. As a result, it can be commercialized with extremely low productivity. In addition, when the purpose is to weaken a considerably large tensile force, as shown in FIGS. 10 to 11, the small bulge portion (9) is used.
On the other hand, the object can be achieved by further connecting a proper number of minute bulges (11), (11) '... Since the attachment of the minute bulging portions (11) (11) '... may make the shape of the balloon unsuitable, it is mainly targeted for the case of a balloon requiring a considerably large internal pressure.

Also, in another embodiment, the folded pieces (12), (13) and (14) of different folds are combined and sandwiched between the two stacked resin films (3) '. Since the same balloon body (10) is manufactured since it is the same as the above-mentioned embodiment, the sandwiching of the other folding pieces (12), (13) and (14) can be changed according to the number of faces, and the combination is free. .
In addition, if the folding part (2) is W-folded and fold-folded,
The number of multifaceted pieces increases, and it becomes easy to obtain a desired three-dimensional toy balloon.

(Effects) As a result of the above, the present invention provides: Since the polyhedral type balloon body (10) can be immediately produced only by the folding means of the balloon material (3) and the heat-sealing cut (6) means of the balloon mode figure (4), it is not a conventional manual work but a conventional method. It is convenient for us to be able to automatically mass-produce this product using the bag making machine, and thus, it will be possible to provide very inexpensive products and the demand will be wide.

2. By providing a small bulge (9) at the intersection (8) where the inner fold line (7) and the heat-seal cut (6) line intersect, there is a certain risk of pinholes and rupture that easily occur at the intersection (8). It is possible to mass-produce toy balloons by a bag-making machine, which is prevented by the above, and is really safe and long-term usability is guaranteed.

3. For the small bulge (9), further minute bulge (11)
By connecting (11) ′ ..., It is convenient to obtain a polyhedral toy balloon that can withstand a considerable tensile force.

4. The balloon material sandwiching the other folding pieces (12), (13), (14) is convenient and convenient for changing the number of faces because the combination of the folding pieces (12), (13), (14) can be easily changed.

And so on.
