Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stick balloon with a display, which is mainly used for cheering and bar gymnastics among stick balloons.

2. Description of the Related Art Conventionally, rod-shaped sticks have come to be used as gymnastic sticks mainly for rehabilitation when cheering on various athletic competitions. For example, in place of cheering by clapping or clapping, which has been conventionally performed by cheering players, two gas-filled stick balloons are beaten against each other to generate sound, which is used to encourage the players. In addition, various SNSs have introduced news that elderly people and patients with intractable neurological diseases who require rehabilitation are using lightweight sticks made of old newspapers as gymnastics aids to improve muscle strength (for example, non-patent literature). 1).
In some cases, signs and phrases are printed on the surface of such sticks to visually appeal to the players and people around them. For example, Patent Document 1 discloses a stick balloon body in an inflated state, which consists of a stick balloon main body that is inflated into a stick shape by filling with gas, and a flag piece with a display pattern that is integrally provided with a mounting part that becomes cylindrical when attached. A stick balloon is disclosed in which a flag piece is attached to a stick balloon body by bringing the inner peripheral surface of an attachment portion into close contact with the outer peripheral surface of the stick balloon.

The stick as a gymnastics aid disclosed in Non-Patent Document 1 is a simple gymnastics stick made by rolling old newspaper into a cylinder and fixing it from the outside with a vinyl tape or the like. While such paper sticks are readily available, they sometimes lose their shape due to moisture absorption when used in places with high humidity, such as around baths and pools. In addition, when it is desired to generate a sound that replaces hand clapping in time with the rhythm during gymnastics, even if cylindrical papers are hit against each other, it is difficult to produce a light and clear sound, and the intensity is weak. Furthermore, it is a laborious task to impart a distinct marking pattern on the surface of the rolled newspaper. The stick balloon disclosed in Patent Document 1 has a display pattern on both the surface of the stick balloon itself and the surface of the flag. Another problem is that when the two stick balloons attached with the flag pieces are to be struck, the flag pieces become an obstacle and must be removed in advance. In addition, once the characters and patterns displayed on the stick balloon main body are printed, it may be difficult to divert them to other uses. For example, it is generally unreasonable to divert a stick for cheering a competition on which the name of the cheering team is printed to a stick for gymnastics.

The present invention has been made in view of the above circumstances, and compared to known stick balloons with display patterns, it is possible to easily change the display pattern according to the purpose and application of use, and To provide a stick balloon with an indication for cheering or bar gymnastics, which is excellent in strength and moisture resistance and which can emit a pleasant sound by striking two sticks.

As a result of extensive studies to overcome the above problems, the inventors of the present invention found that the above problems can be achieved by combining a resin film balloon film having a specific check valve structure and a tubular film with a display. came up with the idea. That is, according to the present invention, a stick balloon with a display shown below is provided.

Embodiments of the present invention will be described below with reference to the drawings. In addition, in all the drawings, the same constituent elements are denoted by the same reference numerals, and the explanation thereof is omitted as appropriate. Also, the drawings are schematic diagrams and do not necessarily match the actual dimensional ratios.

In the embodiment of the present invention, air, nitrogen, helium, or a mixture of two or more of these gases can be used arbitrarily as the gas, but air is preferred because it is safe and highly versatile. FIG. 1 is a perspective view showing an example of a stick balloon with a display (referred to as "stick balloon (A)" in the following description) related to an embodiment of the present invention. The technical idea of the invention will be explained. In the following description, the lower side (short side 1 side) of the stick balloon (A) may be referred to as the "lower end portion" and the upper side (short side 2 side) may be referred to as the "upper end portion" for convenience. FIG. 2 is a cross-sectional view of the XX' cross section of the stick balloon (A) with a display viewed from the short side direction (y-axis direction). FIG. 3 is a front view of a stick balloon (A) with an indicator in a state before gas injection or after degassing. FIG. 4 conceptually illustrates the process of producing a stick balloon (A) with a display from a film bag (hereinafter referred to as “film bag (B)”) and a tubular film 3 related to this embodiment. It is a schematic drawing. FIG. 5 is an enlarged view of the lower end of the film bag (B), conceptually showing an example of the shape and arrangement of the channel fusible zone and the location of the channel port (airway). FIG. 6 is a drawing showing various shape examples of the upper end portion of the film bag (B). FIG. 7 is a conceptual diagram showing an example in which a diameter-enlarging portion is attached to a channel fusion zone or an edge fusion zone provided in a stick balloon (A) with a display.

A stick balloon (A) with a display according to this embodiment is composed of a film bag (B) and a body-wound portion of a tubular film 3 . The film bag (B) is a vertically elongated, substantially rectangular flat bag in which the peripheral edges of a pair of resin film pieces facing each other are sealed by a folding line 4 or an edge fusing band 1 . A partial double-layer structure in which a tubular film 3 with a display is attached to the outer surface of the film bag (B) filled with gas and in a balloon state (hereinafter referred to as "balloon film"). is the stick balloon (A) with a display of the present invention.

The peripheral edge of the film bag (B) may be sealed with either the folding line 4 or the edge fusion band 1, but the use of the stick balloon assumed by the present invention and the inflation molding as the original resin film In view of the fact that the tubular film obtained in 1 is preferred, a film bag in which the long sides 1 and 2 are sealed by the folding lines 4 and the short sides 1 and 2 are sealed by the edge fusion band 1 A shape is preferred. In the sealing with the bending lines 4 on both long sides, the length of the edge fused portion 1 can be shortened, which may improve the airtightness reliability. The present inventor presumes the following as to the reason why the reliability of the airtightness tends to decrease due to sealing by edge fusion. That is, in general, when forming the edge fusible band, fusing work is performed by a heat sealer or the like. The existence or non-existence of wrinkles in the balloon may cause unevenness in fusion bonding strength, resulting in uneven airtightness of the balloon.

If the overall shape of the substantially rectangular film bag (B) related to the present embodiment is vertically long and substantially rectangular, it can exhibit its performance in the intended application of the present invention. For the upper end of the film bag (B), straight type (a), dome type (b), roof type (c) and polygonal type (d) edge cohesive zones as shown in FIG. Various shapes formed from can be exemplified. These are all within the technical scope of the present invention. Also, although not shown, the lower end of the film bag (B) may have various shapes formed by a polygonal edge fusing band or the like, in addition to the linear type shown in FIG. In short, if the overall shape is substantially rectangular, the effect of the present invention can be exhibited, and the shape of the upper end and lower end is appropriately selected by those skilled in the art depending on the intended use of the stick balloon (A). matter. When viewed from the production surface of the film bag (B), it is preferable that both the upper end and the lower end of the film bag (B) are straight, that is, the film bag (B) is completely rectangular. This is because the rectangular shape can reduce the amount of scraps generated when the film piece is cut off from the raw film. In the drawings of the present invention, the film bag (B) has a perfect rectangular shape with folding lines 4 on both long sides and edge fusing bands 1 on both short sides. In addition, in the drawings (FIGS. 1, 3, 4, 5 and 7), a fusing margin 2 is provided on the outside of the edge fusing band 1 on the short side of the film bag (B). However, this is not an essential requirement that the present invention should have. In general, when the edge fusible band 1 is arranged using a heat sealer or the like, it is easier to leave an extra fusible margin 2 at the edge of the film. In addition, after the film bag (B) is filled with gas, the fusing margin 2 is folded along the edge fusible band 1 and then simply fixed to the outer wall of the balloon with an adhesive tape or the like. may be received. On the other hand, if the fusion margin 2 is unnecessary, the fusion may be performed so as not to leave the surplus ear margin, or the fusion margin 2 may be left and cut off after fusion. In this embodiment, the material constituting the film of the film bag (B) is, for example, a thermoplastic synthetic resin film, such as polyethylene resin, polypropylene resin, and vinyl chloride resin. Films may be transparent or opaque. It may also be colored.

The film bag (B) according to this embodiment is a flat sealed two-ply film that is not filled with gas. FIG. 3 shows a front view of a state in which the film bag (B) is inserted into the tubular film 3 in a flat state, viewed from the z-axis direction. Here, the size of the film bag (B) related to this embodiment is not particularly limited, but the length (L) is usually 30 cm to 120 cm, preferably 50 cm to 100 cm. The width (D) is usually between 3 cm and 12 cm, preferably between 5 cm and 10 cm. In the inserted state shown in FIG. 3, by injecting gas from the channel port 7 provided in the film bag (B), a stick balloon (A) with an indication in which the tubular film 3 is wrapped around the body can be obtained. can.

The tubular film 3 with a display according to this embodiment is wrapped around the outer surface of the balloon film 5 in which the film bag (B) is filled with gas. Usually, it is wrapped around the outer surface of the balloon film 5 in a cylindrical shape, preferably at one or more places on the cylindrical portion of the film bag (B). In the case of one place, it is wrapped around the center of the cylindrical part, and in the case of multiple places, it is wrapped at one place each, for example, at the upper end and the lower end. The length (band width) of the tubular film 3 is usually 0.1 to 0.8 times, preferably 0.3 to 0.6 times the length (L) of the film pouch (B). When the band is wrapped around a plurality of places, it is preferable that the total length (band width) is within the above range. One or more marks selected from letters, figures, symbols, patterns, and colors different from the outer surface of the balloon film are displayed on the outer surface of the cylindrical film 3 wound around the barrel. In the drawing, the message "Fight! Go for it!" is written as an example. These signs mainly include messages to inspire the players when cheering for the competition, and messages to help rhythmic movements of gymnasts.

In this embodiment, the material forming the tubular film 3 is, for example, a thermoplastic synthetic resin film, such as polyethylene resin, polypropylene resin, and vinyl chloride resin. The tubular film may be transparent or opaque. It may also be colored. The mark displayed on the outer surface of the tubular film 3 may be printed on the surface of the tubular film 3, or may be handwritten with a marker or the like. Alternatively, the material of the tubular film 3 may be transparent, and a piece of paper with a label may be inserted between the tubular film 3 and the balloon film 5 to form the tubular film 3 with a label as a whole.

It should be noted that the tensile elastic modulus of the material forming the film bag (B) and the material forming the tubular film are limited. That is, when the tensile elastic modulus of the film bag (B) is E1, and the tensile elastic modulus of the cylindrical film 3 wrapped around the body is E2, E1≧E2 is satisfied. This means that the amount of displacement for the same stress must be the same for the tubular film 3 and the film pouch (B), or larger for the tubular film 3 than for the film pouch (B). is shown. Control of the tensile modulus is achieved, for example, by appropriately selecting the density of the resin material.

A preferred aspect of the stick balloon (A) according to the present embodiment has a channel 9 for inflow and outflow of gas. The channel 9 is provided on one of the four sides, preferably on one of the short sides, of the substantially rectangular film bag (B), and the flow path 9 extends parallel to this. It is formed in a cylindrical shape by the arranged flow path fusion band 8 . The width of the channel 9, that is, the distance (inner dimension) between the edge cohesive zone 1 and the channel cohesive zone 8 is usually 3 mm to 15 mm, preferably 5 mm to 12 mm. Both the edge fusion zone 1 and the channel fusion zone 8 have a width of about 0.5 mm to 3 mm. When the flow path 9 is arranged parallel to the long side, that is, when it is formed into a cylindrical shape by the bending line 4 and the flow path fusion band provided parallel to the bending line 4, the stick extends in the length direction. It is not preferable because it may be deformed or bent during the process.

As shown in FIG. 4, after inserting one end of the film bag (B) into the annular gap of the tubular film 3, the film bag (B) is passed through the flow path port 7 provided in the film bag (B). By injecting gas, the film bag (B) is inflated to form a balloon, and the tubular film 3 with the display is elastically adhered to the outer surface of the balloon film 5. A stick balloon (A) can be obtained. A perspective view of an example of a stick balloon (A) with a display according to the present invention is shown in FIG. 2. Here, the average thickness of the inner balloon film 5 is usually 80-200 μm, preferably 100-160 μm, and the average thickness of the outer tubular film 3 is usually preferably 50-150 μm, preferably 60-120 μm. .

The edge fused band 1 and the channel fused band 8 in the film bag (B) according to the present embodiment are provided with enlarged diameter portions that widen so as to partially narrow the width of the channel 9. may be By partially narrowing the channel width, it becomes difficult for the gas accumulated in the space inside the balloon film to flow out. In addition, the presence of the enlarged diameter portion may prevent the fused portion from being peeled off or broken. In FIG. 7, a curved enlarged diameter portion 92 is provided on the wall side of the channel 9 of the edge cohesive band 1, and a curved enlarged diameter portion 91 is provided on the wall side of the channel 9 of the channel cohesive band 8. However, the setting place of this enlarged diameter portion is not limited at all, and the setting place is arbitrary as long as the effect of narrowing the flow path 9 is exhibited. These may be installed at only one place, or may be installed at a plurality of places. The shape of the widened portion may be curved as shown, or it may be square or rectangular.

As shown in the figure, after inserting the film bag (B) according to the present embodiment into the tubular film 3, a syringe-type insufflation needle, for example, is inserted into the channel port 7 provided in the film bag (B). The stick balloon with a display of the present invention can be easily obtained by inserting a needle tube, etc., and filling the gas from the tip of the needle tube. Further, when it is desired to discharge the gas in the space, press with one hand from the outside of the central portion of the balloon, and create a plurality of vertical wrinkles generated near the edge cohesive zone 1 so as to be substantially perpendicular to the cohesive zone. The other hand can be pressed on the outside of the bottom edge so that the part disappears. By this operation, the gas accumulated inside can be easily discharged through the channel port 7, and the film bag (B) and the tubular film 3 can be recovered. If the flat film bag (B) collected in this way is folded into a compact size, it can be stored for a long period of time without being bulky.

A limited number of stick balloons with indications according to the present embodiment can be used because there is no need to use different stick balloons for different uses. On the other hand, a plurality of tubular films with indications are prepared for each use, and the stick balloons with indications for each use can be made by simply wrapping them around the body of a commonly used stick balloon and filling it with gas. It is very convenient because you can
