  Hereinafter, embodiments of a balloon weight and a balloon display according to the present invention will be described with reference to the drawings. 1 to 8 relate to the balloon display 10a of the first embodiment, and FIG. 9 relates to the balloon display 10b of the second embodiment. Note that the balloon displays 10a and 10b are collectively referred to as “balloon display 10” when they are not particularly distinguished.

  As shown in FIG. 1, the balloon display 10a includes a balloon 11 in which a gas having a specific gravity smaller than that of air, such as helium gas, is enclosed, and a balloon weight placed on a placement surface at a predetermined placement location indoors or outdoors. 12 and a string 13 having a predetermined length for connecting the two.

  The balloon 11 is fitted with a tab 16 with an insertion hole 17. The balloon weight 12 has, for example, a color and a shape that allows a viewer to recognize a bird doll. The tab 20 is mounted at the position of the small bird's beak of the balloon weight 12 and has an insertion hole 21. The string 13 is tied to the insertion holes 17 and 21 of the tabs 16 and 20 as connecting portions that can connect the upper end portion and the lower end portion, respectively.

  FIG. 2 shows an enlarged view of the range including the balloon weight 12 of FIG. The balloon weight 12 forms a three-dimensional shape with three surface portions including a left side surface portion 24 a, a right side surface portion 24 b, and a bottom surface portion 25. The peripheral edges of the upper portions of the side surface parts 24a, 24b are welded together to form the first welding range 70. Further, the peripheral edges of the lower portions of the side surface portions 24 a and 24 b are welded to the peripheral edge of the bottom surface portion 25 to form a second welding range 71. The side surface portions 24a and 24b and the bottom surface portion 25 are welded to the adjacent surface portions by the first welding range 70 and the second welding range 71, and form a sealed portion inside.

  In this example, the downward projecting portion 73 extends downward from the boundary line between the right side surface portion 24 b and the bottom surface portion 25, and is bent to the lower side of the bottom surface portion 25. The downward protrusion 73 is provided for attaching the sheet-like valve 75 (FIG. 7) to the main body of the balloon weight 12. The downward projecting portion 73 and the sheet-like valve 75 on the tip side thereof are folded to the lower side of the bottom surface portion 25 and fixed with an adhesive tape or the like so that they cannot be seen from the surroundings when the balloon display 10a is in use. I try to improve the appearance of sex. The downward protrusion 73 and the sheet-like valve 75 will be described in detail after FIG.

  The inside of the balloon weight 12 is a sealed portion that can enclose a liquid, and air 29 as an example of gas and water 30 as an example of a liquid are enclosed in the sealed portion. Since the air 29 has a specific gravity smaller than that of the water 30, the air 29 occupies the upper side of the water 30 in the sealed portion. The weight of the balloon weight 12 is adjusted by the amount of water 30. Into the balloon weight 12, for example, after introducing the water 30 first, air 29 can be further introduced to inflate the whole. The overall weight of the balloon weight 12 is mainly determined by the amount of water 30. The amount of air 29 introduced into the balloon weight 12 is adjusted so that the balloon weight 12 is sufficiently inflated.

  3-8 has shown in order the series of 1st process-6th process which creates the weight 12 for balloons.

  In the first step of FIG. 3, a film member 40 is prepared. In this example, the film member 40 is composed of one vertically long rectangular film 41. As a modification, the film member 40 may be composed of a plurality of stacked films 41.

  The contour line 45 in FIG. 3 is a line obtained by tracing the outline of the side surface portion 24 a and the downward projecting portion 73 of the film member 40. The contour line 45 includes a body portion 46, a beak portion 47 and a downward projecting portion 48 of the balloon weight 12.

  In FIG. 3, for the convenience of explanation, mark lines 42a to 42e are entered. The mark line 42 a to the mark line 42 e are parallel to the short side of the film 41. In FIG. 3, the visible side of the film 41 is referred to as “front surface”, and the invisible side is referred to as “back surface”. When the balloon weight 12 is completed, the front surface and the back surface of the film 41 are the outer surface and the inner surface of the balloon weight 12, respectively.

  In FIG. 4 of the second step, the film 41 is mountain-folded at the mark lines 42b and 42d and valley-folded at the mark line 42c when viewed from the front side. The mark line 42a and the mark line 42e overlap when folded at the mark line 42c to the mark line 42e.

  In FIG. 5 of the third step, an underlay 50 that suppresses heat transfer is inserted into the folding of the film 41. The underlay 50 is inserted into the fold of the film 41 from between the mark line 42b and the mark line 42d (hidden in FIG. 5), and the side edge on the leading end side is in contact with the valley of the mark line 42c. . The cut line 53 extends in a curved shape between the two upper ends of the downward projecting portion 48. The creator (manufacturer) of the balloon weight 12 aligns the heat cutter 52 whose sword tip matches the shape of the cut line 53, pushes it down, and melts it along the cut line 53. . That is, the upper and lower films are cut along the cut line 53 while being welded.

  In FIG. 6 of the fourth step, the cut line 53 of FIG. 5 is melted and a cut 59 is formed there. In the fourth step, the underlay 50 in FIG. 5 is removed, and an all-around heat cutter (not shown) is applied to the film 41 to form the fusing part 58. The fusing part 58 is along the outline 45 (FIG. 5) and includes an upper first welding range 70, a lower second welding range 71, and a welding surface 72. The upper first welding range 70 corresponds to the portion of the contour 45 (FIG. 5) above the mark line 42a. The lower welding range 71 corresponds to a portion of the outline 45 below the mark line 42a. The welding surface 72 corresponds to a portion of the tab 20 excluding the insertion hole 21 (FIG. 2).

  The plurality of layers of the folded film 41 are joined at the portion by the fusing part 58. Further, the film 41 is separated into an inner part and an outer part of the fusing part 58 by the fusing action of the fusing part 58.

  In FIG. 7 of the fifth step, the film 41 folded by the mark line 42b to the mark line 42d becomes the side surface portion 24a, the bottom surface portion 25, and the side surface portion 24b in order from the top in the portion inside the fusing site 58. The upper first welding range 70 welds the upper side edges of the side surface portion 24a and the side surface portion 24b to each other. The lower second welding range 71 welds the peripheral edge of the bottom surface portion 25 and the lower side edges of the side surface portions 24a and 24b to each other.

  In the fifth step, when the lower portions of the side surface portions 24 a and 24 b are expanded and the bottom surface portion 25 is expanded, the cut end 67 is separated from the balloon weight 12. The cut end 67 is an area surrounded by the cut 59 and the lower second welding range 71.

  The sheet-like valve 75 has a pair of seat portions 76a and 76b that are stacked so as to be in close contact with each other so that they can be expanded, and at the time of expansion, a passage that communicates the sealing portion inside the balloon weight 12 with the outside is provided. And has a well-known structure that allows passage of fluid through the passage (for example, Patent Document 1). The T-shaped sheet-like valve 75 has a wide head and legs that extend from the head. The seat portions 76 a and 76 b are welded to the leg portions of the sheet-like valve 75 on both side edges in the width direction by weld portions 78. As a result, the leg portion of the sheet-like valve 75 can form a passage penetrating in the longitudinal direction on the inner surface side when the inner surface side of the seat portions 76a and 76b is expanded. Further, when the leg portions of the sheet-like valve 75 are crushed and flattened, the seat portions 76a and 76b are brought into close contact with each other on the inner surface side, the internal passage is closed, and the sealing portion on the inner surface side of the balloon weight 12 is closed. Hold the seal. In addition, the path | pass of the leg part of sheet | seat part 76a, 76b is set to the diameter which can penetrate the well-known straw used at the time of drinking.

  The cut portion 80 is a portion in which an opening is formed by cutting the end portion of the downward projecting portion 73 projecting from the lower edge portion of the right side surface portion 24b. After the cut portion 80 is formed, the leg portion of the sheet-like valve 75 is inserted into the balloon weight 12 from the cut portion 80 until it completely sunk in the downward projecting portion 73. Thus, the sheet-like valve 75 is exposed from the downward projecting portion 73 only at the head portion as one end portion.

  FIG. 8 shows the sixth step. After the leg portion of the sheet-like valve 75 is inserted into the downward projecting portion 73 in the fifth step of FIG. 7, it is cut so as to cross the range where the lower side of the downward projecting portion 73 and the head of the sheet-like valve 75 are in contact with each other. The opening of the portion 80 is welded to form an additional welded portion 85. In order to prevent the passage between the sheet portions 76a and 76b from being welded by the additional welding portion 85, heat-resistant ink is applied to the facing portion on the inner surface side of the sheet portions 76a and 76b corresponding to the range of the passage. Yes. As a result, the sheet-like valve 75 is fixed to the side portion of the downward projecting portion 73 and is prevented from being detached from the downward projecting portion 73.

  With the completion of the sixth step, the balloon weight 12 is completed. The balloon weight 12 is shipped from the factory in a state where the sealed portion is emptied, that is, in a flat state that is not inflated, and is transported to the user who is the purchaser of the balloon weight 12. The user keeps the sealed portion emptied, that is, flattened until the balloon weight 12 is used. Thus, the transportation and storage of the balloon weight 12 is simplified.

  When using the balloon weight 12, the user opens the sheet portion 76 a, 76 b at the head of the sheet-like valve 75 by picking it with a finger or the like. Then, using a drinking straw (not shown), the straw is inserted into the seat-like valve 75 until the tip of the straw reaches the sealing portion of the balloon weight 12 from the tip of the leg of the seat-like valve 75.

  Next, tap water or the like as a liquid is introduced from the outer end of the straw and led out into the balloon weight 12. When a predetermined amount of water 30 (FIG. 2) is introduced into the sealed portion of the balloon weight 12, the introduction of the water 30 is stopped. The normal amount of water 30 introduced into the sealed portion of the balloon weight 12 is less than the maximum capacity of the sealed portion.

  Therefore, the balloon weight 12 is slightly deflated even after the introduction of water to the sealed portion, which deteriorates the appearance. For this reason, a straw is then added to the mouth and air 29 (FIG. 2) is blown into the balloon weight 12. As a result, the sealed portion of the balloon weight 12 is filled with the air 29 and the water 30, and the balloon weight 12 is swelled to the maximum, so that the appearance is improved.

  After the introduction of the water 30 or the like into the sealed portion of the balloon weight 12 via the sheet-like valve 75, the user crushes the leg portion of the sheet-like valve 75 with a finger to close the passage of the leg portion. As a result, the seat portions 76a and 76b are brought into close contact with each other at the leg portions, and the sealing in the balloon weight 12 is maintained.

  Next, the user can connect both ends of the string 13 having a predetermined length to the insertion hole 17 of the tab 16 on the balloon 11 side and the insertion hole 21 of the tab 20 of the balloon weight 12. As a result, the balloon 11 rises until the string 13 extends straight in the vertical direction. In addition, the balloon weight 12 has a predetermined weight secured by the water 30 and holds the balloon 11 via the string 13.

  The balloon weight 12 has a triangular cross section structure in which the cross section has two side surface portions 24 a and 24 b and one bottom surface portion 25. As a result, in a state where the water 30 is introduced into the balloon weight 12, the bottom surface portion 25 can be brought into contact with the placement surface, so that the sense of stability of the balloon weight 12 can be increased.

  In the balloon weight 12, the lower protruding portion 73 and the head of the T-shaped sheet-like valve 75 protrude from the edge line of the bottom surface portion 25 in a flat state. However, during use of the balloon display 10 a, the downward projecting portion 73 and the head of the sheet-like valve 75 are folded and hidden below the outer surface of the bottom surface portion 25. Thereby, since the downward protrusion part 73 and the sheet-like valve 75 do not inhibit the stability of the balloon weight 12 and are not visually recognized by the observer, the appearance of the balloon weight 12 as a design is improved. be able to.

  The balloon weight 12 may be used disposable or reused. When reusing, the operator separates the balloon weight 12 from the balloon 11, inserts a straw again from the outside of the sheet-like valve 75 to the inside of the seat portions 76 a and 76 b, and pushes the balloon weight 12. The air 29 and water 30 in the balloon weight 12 are crushed and discharged out of the balloon weight 12. As a result, the balloon weight 12 becomes flat as before use. Thus, the balloon weight 12 is stored in the predetermined storage location for the next reuse in the flattened state again.

  FIG. 9 shows a main part of the balloon display 10b of the second embodiment. Elements corresponding to the elements of the balloon display 10a in FIG. The balloon display 10b will be described focusing on the differences from the balloon display 10a.

  The balloon display 10b includes two balloon weights 12a and 12b. The balloon weights 12a and 12b are adjusted in direction so that they face each other, and the insertion holes 21 of the tabs 20 are aligned. The lower end portion of the string 13 is inserted into each insertion hole 21 and tied to both tabs 20. In order to connect the balloon weights 12a and 12b with the tab 20, a string other than the string 13 can be used.

  In the balloon display 10b, balloon weights 12a and 12b express a pair of small birds. Each tab 20 is a beak of each bird, and the two tabs 20 are overlapped and tied with a string 13. The viewer can see the love between the paired small birds from the balloon weights 12a and 12b, and thereby improve the design by using the plurality of balloon weights 12a and 12b.

  FIG. 10 is a diagram showing a balloon weight 12 in which a powder water-absorbing polymer 96 is sealed in a sealed portion. In the above description with reference to FIG. 8, it is stated that the balloon weight 12 is shipped and sold with the sealing portion emptied and flattened. However, as shown in FIG. 10, the balloon weight 12 is used for the user in a state in which a predetermined amount of the water-absorbing polymer 96 is sealed in the sealing portions formed on the inner surfaces of the side surface portions 24a and 24b and the bottom surface portion 25. It can also be made.

  10A shows a working state when the water-absorbing polymer 96 is sealed in the sealed portion in the balloon weight 12, and FIG. 10B shows a balloon weight after the water-absorbing polymer 96 is sealed in the sealed portion. 12 states are shown.

  10A, a funnel 90 has a well-known structure including a hopper portion 91 whose upper end is open, and a pipe portion 92 that hangs down a predetermined length linearly from the central portion of the lower portion of the hopper portion 91. Yes. The outer diameter of the pipe portion 92 is the same as the outer diameter of the straw used when the sealing portion is filled with water 30 (FIG. 2), and can be inserted into the leg passages of the seat portions 76a and 76b. ing.

  The operator pierces the lower end of the pipe portion 92 into the upper end of the passage of the leg portions of the seat portions 76a and 76b, and pushes the pipe portion 92 into the passage until the lower end reaches the sealed portion. Next, the operator puts the powdered water-absorbing polymer 96 into the upper hopper 91. The water-absorbing polymer 96 thrown into the hopper 91 falls in the pipe 92 due to gravity and enters the sealed portion.

  The operator loads a predetermined amount of water-absorbing polymer 96 into the sealed portion, and then removes the funnel 90 from the balloon weight 12. Thus, as shown in FIG. 10 (b), the balloon weight 12 is flattened as much as possible in a state where the water-absorbing polymer 96 is sealed in the sealed portion, and is then packed or boxed for shipping or the like. The

  In the balloon weight 12 containing the water-absorbing polymer 96, the user fills the water 30 using a straw or the like into a sealed portion in which a predetermined amount of the water-absorbing polymer 96 is loaded in advance.

  When the balloon display 10 is in use, a person may accidentally step on the balloon weight 12 containing water 30 with his / her foot or kick it with his / her foot and hit a nearby object strongly. In that case, the film member 40 forming the sealing portion may be torn. However, in the balloon weight 12 containing the water-absorbing polymer 96, even if the film member 40 is torn, the water 30 in the sealed portion is absorbed by the water-absorbing polymer 96 and contained in the gel-like water-absorbing polymer 96. become. As a result, even if the film member 40 is torn, it is prevented or suppressed that the water 30 scatters and wets the surroundings.

  Finally, a modification of the embodiment will be described.

  In the balloon weight 12 of the embodiment, a small bird pattern is printed on the side surface portions 24 a and 24 b and the bottom surface portion 25. However. In the balloon display of the present invention, it is also possible to print sales promotion advertisements and guidance characters and designs on the side surface of the balloon weight.

  The balloon weight 12 according to the embodiment is formed by folding a single film 41 at a mark line 42b and the like, and then welding the side edges and the peripheral edge of each surface portion. However, in the balloon weight of the present invention, the film member may have one or more films. For example, it is also possible to prepare a plurality of films by the number of the surface portions of the balloon weight, that is, by stacking them and then welding the side edges and the peripheral edges of the respective surface portions.

  In the embodiment, it is assumed that the balloon display 10 and the balloon weight 12 are used for business purposes. However, the balloon display 10 and the balloon weight 12 may be used as a figurine by an individual at home.

  In the balloon weight 12 of the embodiment of the balloon weight, the sheet-like tab 20 as the string connecting portion is formed by folding and overlapping the film 41 and then performing planar welding.
