Description

Detailed Description of the Invention (Industrial Application Field) The present invention uses a heat-sealable plastic film (hereinafter referred to as a heat-seal film), which is expanded by ballooning, air ballooning, or gas injection. The present invention relates to a method of manufacturing a floating body (hereinafter referred to as a floating body) that embodies and maintains a desired shape such as a doll animal. In addition, depending on the type of gas injected, a floating object in the present invention may float in the air due to buoyancy even when no external force is applied, or it may expand without floating in the air when no external force is applied. This is a general term for both objects that are placed on the ground, on the floor, etc., while maintaining the desired form.

(Prior art) A sheet of heat-sealable film is used to form a folded part and a non-folded part, and a linear contour (hereinafter referred to as a line) is formed across both parts to match the shape to be processed. (Japanese Patent Application No. 63-66368) (Problem to be solved by the invention) Since the pleats and non-folds are formed using a heat-sealing film, the pleats exist in a folded state between the non-folds. It is formed by folding the heat-sealing film between the folded part and the non-folded part, but the folding work of the heat seal film to form the folded part is not easy for practical use, and it is not possible to mechanize it. Even so, there are problems that cannot be avoided.

In addition, when it is not possible to use different types of heat-sealing films and you wish to obtain a floating body with each part colored in a different color, it is possible to separate the parts according to the design on one heat-sealing film as a raw material. After coloring, the folds must be folded and heat sealed, so if there is even a slight deviation in the folding process, the resulting shape and the coloring will not match, which can be fatal. This may result in a defective product, and for this reason,
Coloring the finished product also has the problem of not being efficient.

(Means for Solving the Problems) The present invention does not have the above-mentioned problems, and moreover, the present invention has a plurality of inflated parts of the same shape obtained from the folds using a heat seal film (hereinafter referred to as multiple inflated parts). This was done in order to easily obtain a floating body having one expanded part (hereinafter referred to as a single expanded part) obtained from a non-folded part, and for this reason, in the present invention, a plurality of heat seal films are used. By forming a folded part and a non-folded part, and applying heat sealing with a linear contour across both parts, multiple expansion parts can be formed in the folded part, and a single expansion part can be formed in the non-folded part. When forming a floating body consisting of a plurality of sheets of heat-sealing film, a plurality of sheets of heat-sealing film consisting of (il flat heat-sealing film, a folded heat-sealing film, a plurality of flat and subsequently folded heat-sealing films, iii) The above-mentioned purpose can be achieved by manufacturing a floating body such as a balloon, balloon, etc. using a heat-sealing film that is either a flat heat-sealing film or a plurality of sheets of heat-sealing film that is flat and then folded. reached.

(Function) The heat-sealing film on which floating bodies are formed can be a flat heat-sealing film, a bent heat-sealing film,
and 3 of the heat-sealed film that was flattened and then folded.
fii), fii
Since the folded portion and the non-folded portion are formed using the three combinations of 1 and fiii), the formation of the folded portion is extremely simple and does not require complicated machines or devices for this purpose. In addition, different types of heat-sealing films can be used to obtain one floating body, and each part can be easily colored as desired.

(Example) Next, before explaining an example of implementing the present invention with reference to the attached drawings, an outline of the method proposed earlier will be explained with reference to FIGS. 15 to 16 (a) and (b). In the proposal, the heat seal film L is folded and the folds
and a non-fold portion Y are formed to form a shape as shown in FIG. The order to obtain such a shape is shown in (a) in Figure 16.
As shown in (B), first, the heat sealing surface 6 of the heat sealing film 1 is placed on the lower side, and the right half is folded to the left as shown by the arrow, with the center being the crease C. 6 Next, make a crease at a position equidistant from the crease C, and fold it to the right as indicated by the arrow D', as shown in FIG. 15. In this case, as shown in FIG. 15, the area between the fold D' and the fold C is the pleated part A, and the area from the fold C to the right end is the non-folded part B. In this case, the heat sealing surface 6 of the heat sealing film l is
Even when folded, they are folded so that they are facing each other. By heat-sealing the folded heat-sealing film 1 with a linear contour 7 over both the pleats A and non-folds B as shown in FIG. A floating body 10 as shown in FIG. 4 is obtained in which a plurality of expansions 8,8' are formed in the pleats A and a single expansion 9 is formed in the non-folds B. This is an example of a method of obtaining a floating body using a heat-sealing film according to the previous proposal, but since such a previous proposal has the above-mentioned drawbacks, in the present invention, multiple sheets are used. A heat seal film of (i
), (ii), and fiii), namely (i) a plurality of sheets consisting of a flat film and a folded film, (a plurality of sheets consisting of a Lit flat film, a folded film, and a flat folded film), ( iii) A floating body is obtained by using any one of a plurality of combinations consisting of a flat film and a flat folded film. Obtaining a floating body using a plurality of sheets will be explained with reference to FIGS. 1 to 4. FIG. -Nylon film 2
One side is coated with aluminum vapor deposition 3, and the other side is coated with an anchor coating agent 4, and then polyethylene resin is laminated 5 using a melt extrusion method, and this polyethylene resin laminate 5 imparts heat sealability. , a heat-sealing film 1, and the laminated surface 5 is called a heat-sealing surface 6. Depending on its shape, this heat-sealing film 1 can be classified into a flat film IX, a folded film IY, and a flat folded film 12. Examples of the flat film 1x and folded film 1Y are shown in FIG. 2, and examples of the flat folded film 1z are shown in FIG. 10. In the case shown in FIG. 2, a folded film lY is sandwiched between the flat films IX and IX', and in this state, as shown in FIG. The floating body 10 is obtained by heat sealing. At this time, the end 11 of the flat film lx, the end 11' of IX', the end 11- . 11'' are overlapped so that they match each other.The floating body 10 obtained in this way
As shown in a plan view in FIG. 4, there is a gas inlet 12 at the right end, two spherical multiple expansion parts 8.8' on the left side, and a connection between the gas inlet 12 and the multiple expansion parts 8.8'. A floating body 10 is formed with a single spherical expanded portion 9 formed therebetween. To explain this in more detail, when the flat films 1x and IX' are overlapped, the folded film IY is folded in two.
The part where the folded film IY overlaps with the flat film IX, 1x' becomes the fold part A, and the folded film IY overlaps with the flat film IX, L.
The portion that does not overlap with X' becomes the non-fold portion B, and heat sealing is performed as a linear contour 7 spanning both of these pleat portions A and non-fold portion B. The linear contour 7 shown in FIG.
This is the part of the linear contour 7 that follows this straight part 7', and the circular part 7'' in the non-fold part B becomes one spherical shape which is the single expanded part 9 of the obtained floating body 10. The circular portions 7'' in the folds A, which are part of the linear contour 7 and following this, are the multiple expansions 8.8' of the obtained floating body 1O, which are the linear contours that should become two spheres. This is the outline 7 part. In this case, the gas inlet 12 must be provided in the non-folded part B, and the single expansion part 9 formed by this non-folded part B becomes one bulge. In addition, the plurality of expansion parts 8.8' formed by the pleats A are such that the folded film IY between the flat films IX and LX' can be used as one heat seal film folded in two as shown in FIG. If there is,
This results in two multi-inflation portions 8.8', which are two bulges. The number of multiple expansions is therefore determined by the number of folded films IY between the flat films IX, LX'.

Although FIGS. 2 to 4 have explained a case with one fold and one non-fold, FIGS. Then, fold the folded films IY and IY' by 2 pieces each.
This is folded in half and stacked on the left and right sides between the flat films IX and IX'. At this time, the left ends of the flat films IX and IX' are made to coincide with the left end of the folded film IY. Further, the right ends of the flat films 1x and LX' are made to coincide with the right ends of the folded film IY'.

At this time, the flat films IX, LX' and the folded film I
The portions where Y and IY' overlap are the pleats A and A', and the portion where only the flat films 1x and 1x' overlap is the non-fold portion B. In this state, heat-sealing the surface of the uppermost flat film IX with the linear contour 7 to obtain the floating body 10 is the same as shown in FIGS. 2 to 4, but this sixth The cotton-like contour 7 shown in the figure is the figure of a horse, and the non-fold part B is the part that should become the tail of the horse. The parts that are to become the torso 13, neck 14, and head 15 are heat-sealed with a part of the linear contour 7, and the gas inlet 12, which is the horse's tail, the horse's trunk 13, neck 14, and head 15 are sealed. The part that should become the single expansion part 9. In addition, in the fold A, the part that should become the horse's ear 16, 16' is the linear contour 7.
Heat-sealed with one part. In addition, in the fold A', the portions that should become the front legs 17 and the rear legs 17' are 1 of the linear contour 7.
heat sealed in place. In this way, the tail portion as the gas inlet 12, the body portion 13, the neck portion 14, and the head portion 15, which are the portions heat-sealed to the non-fold portion B, are expressed as a single inflatable portion 9. Also, the part heat-sealed to the fold A' becomes two ears 16.16', the part heat-sealed to the fold A' becomes the front leg 17, and the rear leg 17' has two more front legs 17.2. It is expressed as the hind leg 17'.

Is it also each one? It is expressed as an I number expansion of 8.8'. Note that when the floating body 10 is represented as a horse, parts other than the above-mentioned parts such as eyes, nose, mouth, etc., are to be represented by using a heat-sealable film in advance when not using heat-sealing means. Printing may be performed on necessary portions.

In cases where the folds are formed horizontally or vertically, it is only necessary to select an appropriate shape.
In the explanation so far, we have shown a floating body with two folds, that is, two multi-inflated parts, but if you want to have three or more expanded parts, please refer to Figure 8 or 9. As shown in FIG. 8, it is also good to increase the number of folded films lY between the flat films IX and IX', or to use folded films lY with different bending widths. By using three folded films IY, the number of multiple expansion parts is four, and the one in Figure 9 is a folded film IY with short and long folding widths.
This shows what is used.

Above, in FIGS. 2 to 9, it has been explained that a floating body is obtained using the flat film 1x and the folded film lY, but in FIG. Figures 11 to 14 show the overlapping state of the films when a floating body is obtained using a flat folded film IZ and a flat folded film IZ. This figure shows how the films are stacked to form a body.

The heat-sealing film used in the present invention is a film that has heat-sealing properties on one side of the film and does not have heat-sealing properties on the opposite side, such as a film with metal vapor deposition on one side of a plastic film, or a film with metal vapor deposition on one side of a plastic film. Various materials are used, such as those coated with a resin having a melting point lower than the melting point of the plastic film, and the resin-coated surface is a surface having heat sealability.

It is necessary to consider the gas permeability of the heat-sealable film of the floating body obtained by the present invention depending on how it is used. In other words, if you want to keep the floating body inflated for a longer period of time, it is necessary to select a film with good gas barrier properties that will not allow the injected gas to permeate and escape. There is no need to worry too much about time, there is no need to pay attention to the gas barrier properties of floating objects, and even more, when it comes to things like balloons released inside a large dome, there is no need to worry about time. Once suitable, the balloon may lose its buoyancy as the injected gas dissipates and you want it to fall to the ground. In such cases, it is necessary to select a material with appropriate gas barrier properties. Furthermore, the floating bodies obtained by the present invention are not limited to those floating in the air, but also include those placed on the ground, floor surface, etc., and simply standing upright. In this case, it is also desirable that a pump, pressurized gas, etc. be able to be introduced into the gas inlet in conjunction with the permeation and dissipation of gas.

For the heat sealing performed in the present invention, any heat sealing means such as a hot plate seal having a seal shape, an impulse seal, a high frequency seal, an ultrasonic seal, etc. can be employed.

(Effects of the Invention) Since the present invention is configured as described above, it produces the effects described below. A floating body is manufactured by forming a pleated part and a non-folded part using a single heat-sealing film, and heat-sealing across both parts with a linear contour that matches the shape to be processed. In the previous proposal, the heat seal film used for this is 1
Because it is a single sheet, the operation for forming folds is not easy and it is difficult to perform it efficiently. However, in the present invention, the heat seal film can be used as a flat film, a folded film,
There are three types of flat folded films, and these are
) flat film and folded film, fiil flat film and folded film and flat folded film, (iii
Since the combinations of flat films and flat folded films are divided into three groups, and multiple sheets within each combination are overlapped to form pleats and non-folds, the formation of pleats is easy. It is simple and easy, and moreover, it is possible to easily obtain a complex plurality of expanded parts that cannot be obtained by folding a single sheet of heat-sealing film. As a result, floating bodies can be provided efficiently and at low cost, and this is particularly effective when the number of folds increases or when it is desired to obtain a structure with different widths of folds.

Furthermore, since there are multiple sheets, it is possible to arbitrarily combine two or more types of films, and it is also possible to easily obtain a floating object with rich colors by arbitrarily combining films of different colors. became.

These improvements in workability make it easier to obtain floating bodies of special shapes and arbitrary colors, and workability is significantly improved.By combining the films of type 11, it is possible to control the weight and improve buoyancy. This is a remarkable invention as it allows for easy adjustment of gas barrier properties and can greatly contribute to cost reduction.
