Description

  The present invention relates to a display balloon that is displayed for decoration indoors or outdoors in, for example, a department store or a showroom.

  Since the display balloons as described above are displayed for a relatively long period of time, it is required to keep the initial shape without air being removed during that time. For this reason, a general rubber balloon that loses air in a day or two cannot be used as a display balloon.

  For this reason, balloons made of a soft vinyl chloride resin film (or sheet) used for beach balls or the like are used as display balloons that are arranged outdoors. As shown in FIG. 7, this balloon 11 is constructed by welding six lemon-shaped sheets 12 and connecting them into a spherical shape like a western-style pattern and attaching a gas inlet 13 with a stopper. ing. A string 14 is connected to the gas inlet 13 of the balloon 11 and a large number of balloons 11 are bundled into various shapes to form a display for decoration.

On the other hand, Japanese Utility Model Publication No. 5-34711 discloses a balloon toy as shown in FIG. This balloon toy 21 has an outer skin 25 formed by polymerizing two plastic films 22 having a dense material structure and deformable, and welding a peripheral edge 24 leaving an insertion port 23. Then, the rubber balloon 26 is inserted into the outer skin 25, the nozzle portion 27 is taken out from the insertion port 23 of the outer skin 25, the rubber balloon 26 is inflated and brought into close contact with the inner surface of the outer skin 25, and then the nozzle portion 27. To prevent gas from escaping.
No. 5-34711

  However, the conventional beach ball type balloon 11 shown in FIG. 7 is expensive because the six films 12 are welded and bonded together, and the work of tying the string 14 to the gas inlet 13 is difficult when making a display. Since this is necessary, there is a problem that workability is poor.

  On the other hand, in the balloon toy 21 shown in FIG. 8, the durability of the internal rubber balloon 26 is poor particularly when the balloon toy is arranged outdoors. Similarly to the balloon of FIG. There is a problem in that workability is poor because work for tying strings is required.

  The present invention has been made to solve the above-mentioned problems of the prior art, and its purpose is to have good durability that can be used for displays, a simple structure that can be manufactured at low cost, and a large number of products. An object of the present invention is to provide a display balloon having good workability in assembling a display.

  In order to achieve the above object, a balloon for display according to the present invention is formed integrally with a balloon body formed by polymerizing two synthetic resin films and thermally welding a peripheral portion thereof, and the balloon body film, A flap extending in a strip shape from a part of the periphery of the balloon body, and provided in any part of the balloon body so that gas can be injected into the balloon body, and sealing the gas injected into the balloon body And a gas inlet having means capable of stopping.

  In carrying out the present invention, it is preferable to use a soft synthetic resin film having a thickness of 0.1 to 0.3 mm as the film. In this case, a vinyl resin such as a vinyl chloride resin is preferably used as the soft synthetic resin. If the thickness is 0.1 mm, sufficient strength, weather resistance and gas impermeability cannot be obtained.If the thickness exceeds 0.3 mm, the rigidity of the film increases and the balloon is inflated into a clean shape. It becomes difficult.

  The flap preferably has a length of 5 to 20 cm, and a plurality of holes for inserting the string or pipe are formed at predetermined intervals along the longitudinal direction.

  The balloon of the present invention is inflated by injecting a gas such as air from a gas inlet, and sealed by a sealing means provided at the gas inlet, thereby obtaining a balloon body inflated according to the shape of the film. . In this case, for example, when the shape of the film is circular, it becomes a swelled disk shape when the gas injection pressure is not so high, but since the film is stretched by increasing the gas injection pressure, the shape should be nearly spherical. You can also.

  By binding the flap of the balloon thus inflated to a binding member, a large number of balloons can be bound into a desired shape, and a powerful display as a whole can be configured. In this way, the display can be made by using the flap provided integrally with the balloon in advance, so that the operation can be performed easily and quickly. Further, when at least one hole for inserting a string or a pipe is formed in the flap, a large number of balloons are bundled into a desired shape by passing the string or the pipe through the hole provided in the flap. Can be made.

  In a preferred embodiment of the present invention, when a soft synthetic resin film having a thickness of 0.1 to 0.3 mm is used as the film, it is possible to provide a display balloon capable of obtaining sufficient durability even when used outdoors. .

  In addition, when the length of the flap is 5 to 20 cm and a plurality of holes for string or pipe insertion are formed at predetermined intervals along the longitudinal direction of the flap, the balloons are bound by the string or pipe. The advantage is that the flap length sometimes required can be adjusted by simply selecting the flap holes.

  As described above, according to the balloon of the present invention, two synthetic resin films are polymerized and the peripheral edge portion is formed by heat welding. The shape can be maintained by preventing the detachment. In addition, since a large number of balloons can be easily bound by binding the flap formed integrally with the film to some binding member, the operation of making a display can be performed easily and quickly. Further, when at least one hole for inserting a string or pipe is formed in the flap, a large number of balloons are bundled into a desired shape by passing the string or pipe through the hole provided in the flap. Can be made. Furthermore, since it can be almost manufactured simply by polymerizing two synthetic resin films and thermally welding the peripheral portion, the manufacturing is simple and the cost is low.

  1 to 3 show an embodiment of a display balloon according to the present invention. FIG. 1 is a plan view showing a state before the balloon is inflated, FIG. 2 is a side view showing the state before the balloon is inflated, and FIG. 3 is a side sectional view showing the state where the balloon is inflated.

  The balloon 31 is formed of two films 32 and 33 made of a soft vinyl chloride resin having a thickness of 0.2 mm and forming a circular shape as a whole. The films 32 and 33 have a circular shape as a whole, but have flap portions 32a and 33a that protrude from the part of the periphery to the outside in the radial direction. And these two films 32 and 33 are superposed | polymerized and the peripheral part is welded. In addition, it is preferable to cut and form the welding part 34 simultaneously with welding so that a welding allowance may not be left as much as possible.

  The welding part 34 is formed in the circular peripheral part (a boundary part with flap part 32a, 33a) of the films 32 and 33 and the peripheral part of flap part 32a, 33a, and welds a circular peripheral part. Thus, a balloon body in which a space for gas filling is formed is formed. The flap portions 32a and 33a are welded to form a single flap 35, and three holes 36 are formed in the flap 35 at predetermined intervals along the longitudinal direction thereof. These holes 36 are used for inserting a string or a pipe for binding the balloons. In this embodiment, the flap 35 has a length of 12 cm and a width of 2 cm.

  A known gas injection port 37 used for a beach ball or the like is attached by welding to a location slightly outside from the center of one film 32. The gas injection port 37 includes a port portion 38 serving as a gas injection port, a connection band 39 connected to the port portion 38, and a plug portion 40 provided at the tip of the connection band 39. Then, after inflating the balloon 31 by injecting a gas such as air from the gas injection port 37, the connecting band 39 is bent and the mouth portion 38 is closed with the plug portion 40 as indicated by the imaginary line in FIG. Thus, the injected gas can be sealed. Further, the gas inlet 37 can be pushed into the balloon 31 as shown in FIG. 3 after the balloon 31 is inflated.

  The balloon 31 can be inflated into a shape as shown in FIG. 3, for example, by injecting a gas such as air from the gas injection port 37. However, by further increasing the internal gas pressure, the films 32 and 33 made of a soft vinyl chloride resin can be stretched and expanded into a substantially round spherical shape.

  5 and 6 show how the balloon 31 is used. That is, as shown in FIG. 5, after the balloons 31 are inflated into a substantially round spherical shape, a large number of balloons 31 are bundled through the pipes 41 in the holes 36 of the flap 35. When the balloons 31 are bundled and closely arranged in this way, a display 42 having a shape as shown in FIG. 6, for example, can be produced. In this case, if balloons 31 having different colors such as red and white are used alternately, a balloon 31 having different colors 31a and 31b arranged in a spiral shape can be obtained as shown in FIG. .

  FIG. 4 shows another embodiment of the display balloon according to the present invention.

  The display balloon 51 is formed by polymerizing two substantially circular films 52 and 53 obtained by metal deposition on a 20 μm thick polyethylene film and welding the peripheral edges. The films 52 and 53 have flap portions 52a and 53a that are elongated in the radial direction from a part of the peripheral edge of the circular portion, and the welded portion 54 is connected to the peripheral portion of the circular portion (with the flap portions 52a and 53a). (Including the boundary portion) and the periphery of the flap portions 52a and 53a. And the balloon main body in which the space filled with gas was formed is comprised by welding the periphery of the said circular part.

  The flap portions 52 a and 53 a of the upper and lower films 52 and 53 are integrated by a welded portion 54 to constitute a single flap 55. In this embodiment, a check valve 56 that also serves as a gas inlet is inserted inside the flap 55 and is welded to the upper and lower films 52 and 53 when the weld portion 54 is formed.

  The check valve 56 has a structure as shown in, for example, Japanese Utility Model Publication No. 1-335019, and is formed by polymerizing a plurality of films. Since such a check valve is already well known and frequently used in commercially available polyethylene balloons, detailed description thereof will be omitted. The check valve 56 is inserted between the flap 55 and the balloon body side, and the base side is a gas injection port 57.

  A slit 58 is formed in the flap portion 52 a of one film 52 at a portion slightly closer to the tip than the gas injection port 57 of the check valve 56. The tip of the straw 59 is inserted from the slit 58, the tip of the straw 59 is inserted into the gas inlet 57 of the check valve 56, and a gas such as air is blown through the straw 59, so that the balloon can be inflated. It can be done.

  Further, two holes 60 for passing a string or pipe used for display are formed at a predetermined interval at the tip of the flap 55 where the slit 58 is formed.

  According to this display balloon 51, by inserting the tip of the straw 59 through the slit 58, and further inserting the tip of the straw 59 into the gas inlet 57 of the check valve 56, and blowing in gas such as air, Balloons can be inflated. Further, by passing a string or a pipe through the hole 60 of the flap 55, a large number of balloons 51 can be bundled to make a display as shown in FIG. 6, for example.
