Description

  The present invention relates to a balloon with a mouth tube having a structure in which a mouth tube made of resin is attached to a mouth-wound portion of a balloon.

  As a support method when watching a game at a professional baseball stadium, it is widely practiced to fly long and narrow balloons all at once in the air with air inside. That is, the air intake port of the balloon inflated with air is closed by hand and held so that the air does not flow out, and the air is ejected from the air intake port by releasing it at an appropriate timing. The jet power is used as a driving force to fly into the air. By blowing balloons together into the air, the players are inspiring and the game is excited.

  A balloon mouthpiece is generally provided with a cylindrical mouthpiece made of resin having a whistle function, and a sound is generated when air is ejected from the mouthpiece. Hereinafter, this type of balloon is referred to as a “balloon with a mouthpiece”. Attachment of the mouth tube to the balloon is performed, for example, as shown in Patent Document 1, by inserting the mouth-wound portion of the balloon into a ring-shaped recess provided on the outer peripheral side wall of the mouth tube. In other words, the periphery of the mouth tube is strongly tightened by the elastic contraction force of the mouthpiece of the balloon inserted into the recess of the mouth tube, thereby fixing the mouth tube to the balloon.

  By the way, in order to inflate the balloon with a mouth tube, there is a method using an air pump. However, in many cases, a method in which a mouth tube is held by a mouth and a breath is blown is performed.

Utility Model Registration No. 3153581

  However, in the case of the above conventional example, the mouthpiece is fixed to the balloon only by inserting the mouthpiece of the balloon into the recess of the outer peripheral side wall and strongly tightening the circumference of the mouthpiece. Pulling between them could cause the mouthpiece to come off the balloon.

  For example, when the mouth tube is put in the mouth and breathing into the balloon, if the mouth tube comes off the balloon, there is a possibility that the mouth tube may be accidentally swallowed.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to provide a balloon with a mouth tube that does not cause the mouth tube to be detached from the balloon, has no risk of accidental ingestion, has a simple structure, and can be easily assembled. There is.

The present invention is a balloon with a mouthpiece in which a mouthpiece of a balloon body is attached to a mouthpiece attaching portion provided on an outer periphery of a resin mouthpiece, and the mouthpiece is cylindrical and the mouthpiece is attached to the outer periphery. And a mouthpiece covering member that is attached to the outer periphery of the mouthpiece body and covers the outer periphery of the attached mouthpiece to prevent its detachment. .
Since the mouthpiece covering member covers the mouthpiece attached to the outer periphery of the mouthpiece body, it is possible to reliably prevent the mouthpiece from being detached from the mouthpiece. This can reliably prevent the possibility of accidentally swallowing the mouthpiece. Further, since it is only necessary to attach a mouth-wrapping cover member to the outer periphery of the mouthpiece body, the structure is simple and the assembly can be easily performed.

Further, the present invention is the above balloon with a mouth tube, wherein the mouth-winding mounting portion is constituted by a ring-shaped recess provided on the outer periphery of the mouth tube body, and one of the opposing side walls in the recess. It is preferable that the side wall is a locking portion for locking a locking claw provided on the mouth-wrapping cover member.
Since one side wall of the mouthpiece mounting portion is used as a latching portion, both can be integrated by simply latching the latching claw of the mouthpiece covering member to this latching portion. Easy to install.

Further, the present invention is the balloon with a mouth tube, wherein the locking claw is provided in a plurality of rings at a predetermined interval so as to protrude toward the inner peripheral side of the mouth winding covering member. preferable.
This makes it easier for the locking claws to spread outward when the mouthpiece covering member is attached to the mouthpiece main body (the expanding elastic force becomes larger), making it easier to attach the mouthpiece covering member to the mouthpiece body. Become. Furthermore, since the concavity and convexity due to the portion with and without the locking claw are pressed against the mouth winding, it is possible to reliably prevent slippage in the rotation direction of the mouth winding. In addition, the wrapping has a large variation between the thick and thin ones, but the variation can be absorbed in the concave and convex concave spaces. For this reason, it is possible to easily cope with the variation in the mouth-wrapping. For example, the mouth-wrapping is thick so that it is difficult to attach the mouth-wrapping cover member. Can also be prevented.

Moreover, this invention is a balloon with the above-mentioned mouth tube, Comprising: The outside diameter dimension of the other side wall facing this is enlarged rather than the outside diameter dimension of said one side wall in the recessed part which comprises the said mouth winding attachment part. Thus, when the other side wall is used as a stopper portion and the mouth-wrapping covering member is inserted into the outer periphery of the mouthpiece body from the one side wall side and the locking claw is locked to the locking portion, It is preferable that the stopper portion is brought into contact with the end face of the wrapping covering portion to prevent the movement.
As a result, when the wrapping cover member is inserted into the outer periphery of the tube body and the locking claw is locked to the lock portion, the inserted wrapping member passes through the periphery of the tube body. It is possible to reliably prevent the fear of being lost.

  According to the balloon with a mouthpiece according to the present invention, the mouthpiece is not detached from the balloon, there is no risk of accidental ingestion, the structure is simple, and the assembly can be easily performed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic perspective view of a main part of a portion near a mouth tube 20 of a balloon 1 with a mouth tube according to an embodiment of the present invention. FIG. 2 is a longitudinal sectional view of a portion near a mouth tube 20 of the balloon 1 with a mouth tube. FIG. 4 is an exploded perspective view of a portion in the vicinity of the mouth tube 20 of the balloon 1 with a mouth tube, and FIG. 4 is an exploded vertical sectional view of a portion in the vicinity of the mouth tube 20 of the balloon 1 with a mouth tube. In the following description, the direction in which the balloon body 10 is viewed from the mouthpiece 20 is referred to as “up”, and the opposite direction is referred to as “down”.

  As shown in these drawings, a balloon 1 with a mouthpiece includes a balloon body 10 made of a stretchable material such as natural rubber, and a mouthpiece 20 attached to a mouthpiece 11 of the balloon body 10. Has been.

  The balloon body 10 swells as shown in FIG. 1 when air is injected, and the upper part thereof is a thin and long substantially cylindrical shape (not shown). However, the shape of the balloon body 10 is not limited to the above, and various modifications are possible, and any shape may be used. The mouth wrap 11 for injecting air of the balloon body 10 is formed in a ring shape and has a desired thickness.

  The mouthpiece 20 includes a tubular mouthpiece body 30 and a ring-shaped mouthpiece covering member 70 attached from one end side (the lower side in the drawing) of the mouthpiece body 30. ing. From the opposite end side (upper side) where the mouthpiece covering member 70 of the mouthpiece body 30 is attached, the mouthpiece 11 portion of the balloon body 10 is attached.

  FIG. 5 is an exploded perspective view of the mouthpiece body 30. As shown in FIGS. 5 and 4, the mouthpiece body 30 is configured by integrating a first body portion 31 and a second body portion 51, and the mouthpiece body 30 that is integrated is shown in FIG. 2. Thus, it is cylindrical as a whole, and both end surfaces thereof are covered by thin plate-like cover portions 33 and 53, and circular openings 35 and 55 are provided at the centers of the cover portions 33 and 53. Further, on the outer peripheral surface of the mouthpiece main body 30, a pair of ring-shaped (ridge-shaped) projecting portions 37 and 57 projecting outward in the radial direction are formed at a predetermined interval. The formed ring-shaped recess is used as the mouthpiece mounting portion 21. On the other hand, the outer diameter of the upper protrusion 57 is formed larger than the outer diameter of the lower protrusion 37. Then, the outer diameter dimension of one side wall (side wall on the protruding part 57 side) in the concave portion constituting the wound winding attachment part 21 is determined from the outer diameter dimension of the other side wall (side wall on the protruding part 37 side) opposite to this. The one side wall (side wall on the protruding portion 57 side) is used as a stopper 59, and the other side wall (side wall on the protruding portion 37 side) is used as a locking portion 39.

  The first body 31 constituting the mouthpiece body 30 is a molded product of synthetic resin, and the cover 33 and the opening 35 are provided on one opening side of the cylindrical first side wall 41, and the first side wall is formed. The protrusion 37 is provided on the outer periphery of 41, and a cylindrical mouth-wrap support 43 is provided on the surface of the protrusion 37 on the second main body 51 side. The inner diameter dimension of the wound support part 43 is larger than the outer diameter dimension of the first side wall part 41, and an insertion part 45 formed of a ring-shaped recess is formed between the two. Further, the tip end of the wound support portion 43 protrudes toward the second main body portion 51 side from the tip end of the first side wall portion 41.

  The second main body 51 is a synthetic resin molded product, and the cover 53 and the opening 55 are provided on one opening side of the cylindrical second side wall 61, and the protrusion is formed on the outer periphery of the second side wall 61. 57 is provided. A stepped portion 63 is provided on the inner peripheral surface of the second side wall portion 61 so that the lower inner diameter dimension is larger than the upper inner diameter dimension.

  Then, if the second side wall portion 61 of the second main body 51 is press-fitted (inserted) into the insertion portion 45 of the first main body 31, both are fixed together as shown in FIG. 30 is configured. That is, when the thickness of the lower end side portion of the second side wall portion 61 is slightly larger than the gap size of the insertion portion 45, the second side wall portion 61 is press-fitted into the insertion portion 45. Both are configured to be firmly fixed. In addition, you may integrate between the 1st main-body part 31 and the 2nd main-body part 51 by another engagement structure, an adhesive material, etc.

  The mouth-wrapping cover member 70 is a synthetic resin molded product and is formed in a cylindrical shape. The inner diameter dimension of the opening 73 on the lower side of the wound winding covering member 70 is formed to be slightly larger than the outer diameter dimension of the protruding portion 37 of the first main body 31. The inner diameter dimension of the upper opening 75 of the mouth-wrapping cover member 70 is larger than the inner diameter dimension of the lower opening 73 by a predetermined dimension. Further, a plurality of locking claws 71 are provided in a ring shape at a predetermined interval on the inner peripheral side surface of the wrapping covering member 70 so as to protrude inward. Each locking claw 71 is formed so as to protrude toward the inner peripheral side while gradually inclining downward. The inner diameter dimension of the circle connecting the tips of the respective locking claws 71 is configured to be smaller than the outer diameter dimension of the projecting portion 37 and larger than the outer diameter dimension of the wound support portion 43. The inner peripheral surface of each locking claw 71 is curved so that the longitudinal section thereof is substantially arcuate, and the curved surface has a gradually increasing inclination angle from the upper side to the lower side. It has become.

  Next, an attachment method for attaching the mouthpiece 20 to the mouthpiece 11 of the balloon body 10 will be described. First, in FIG. 3, the mouthpiece 11 of the balloon body 10 is spread and attached to the outer periphery on the upper end side of the mouthpiece body 30. As shown in FIG. 6, the mouth wrap 11 is inserted and mounted in the mouth wrap attachment portion 21 over the protruding portion 57. The mouthpiece 11 is brought into elastic contact with the bottom surface of the mouthpiece attachment portion 21 (that is, the outer peripheral surface of the mouthpiece support portion 43).

  Next, the mouth-wrap covering member 70 is inserted and attached from the lower end side of the mouthpiece body 30. At this time, the first side wall 41 of the mouthpiece main body 30 is inserted into the openings 73 and 75 of the mouth wrapping member 70, and the protrusion 37 is moved over. At this time, the outer diameter of the protrusion 37 is smaller than the inner diameter of the circle connecting the tips of the locking claws 71 of the wound covering member 70. Due to the elastic expansion of the member 70 in the radial direction, the protruding portion 37 is overcome by a snap-in method, and each locking claw 71 is locked to the locking portion 39 of the protruding portion 37 as shown in FIG. At the same time, the mounted wound 11 is slightly crushed and deformed by the inner peripheral surface of the wound covering member 70, and the outer periphery of the wound 11 is covered by the wound covering member 70. 11 is reliably prevented. In other words, since the mouthpiece 11 is housed in the space surrounded by the outer peripheral surface of the mouthpiece support portion 43, the pair of protrusions 37, 57, and the mouthpiece covering member 70, the mouthpiece 11 is reliably detached. Is prevented. This can reliably prevent the mouth tube 20 from being accidentally swallowed from the balloon body 10. Further, since the mouthpiece 20 is configured only by mounting the mouth-wrapping covering member 70 on the outer periphery of the mouthpiece body 30, the structure is simple and the assembly is easy.

  Further, in the mouthpiece 20, as described above, one (lower side) side wall of the mouthpiece mounting portion 21 formed of a recess is used as a locking portion 39, and the hooking covering member 70 is locked to the locking portion 39. Since both can be integrated only by latching the nail | claw 71, mounting | wearing of the mouth-wrapping covering member 70 to the mouthpiece main body 30 can be performed easily also from this point. Furthermore, since the latching claw 71 is provided in a ring shape at a predetermined interval so as to protrude to the inside of the wrapping covering portion 70, one claw is formed in a ring shape on the inner periphery of the wrapping covering portion 70. Compared with the case where it is provided on the surface, when the mouth covering member 70 is attached to the mouthpiece main body 30, the locking claw 71 becomes easier to spread outward (the spreading elastic force becomes larger), and the mouth covering member 70 is more It becomes easy to attach to the tube body 30. Furthermore, since the ring winding 11 is pressed against the ring winding 11 by a portion having the locking claw 71 and a portion without the locking claw 71, slippage in the rotation direction of the ring winding 11 can be reliably prevented. Further, the mouth wrap 11 has a large variation between the thick and thin ones, but the variation can be absorbed by the space in the concave and convex portions. That is, even if the thickness of the mouthpiece 11 differs depending on the product, it is not difficult to attach the mouthpiece covering member 70 to the mouthpiece main body 30, and the variation can be dealt with.

  Furthermore, in the above-mentioned tube body 30, by making the outer diameter of the side wall of the protruding portion 57 facing this larger than the outer diameter of the side wall of the protruding portion 37 in the concave portion constituting the mouth winding attachment portion 21, Since the side wall of the projecting portion 57 is used as the stopper portion 59, the mouth-wrapping cover member 70 is inserted into the outer periphery of the mouthpiece main body 30 from the projecting portion 37 side, and the locking claw 71 is locked to the locking portion 39. At this time, the stopper portion 59 comes into contact with the end surface of the mouth-wrapping covering member 70 via the balloon body 10. For this reason, when the wrapping covering member 70 is inserted into the outer periphery of the mouthpiece main body 30 and the locking claw 71 is locked to the locking portion 71, the inserted wrapping covering member 70 becomes excessive. The risk of passing through the outer periphery of 30 and detaching to the opposite side can be reliably prevented. That is, the protruding portion 57 has both an attachment function for attaching the balloon body 10 and a separation preventing function for preventing the balloon body covering member 70 from being separated to the opposite side when the mouth-wrap covering member 70 is attached.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical model registration claims and the technical idea described in the specification and drawings. Deformation is possible. It should be noted that any shape, structure or material not directly described in the specification and drawings is within the scope of the technical idea of the present invention as long as the effects and effects of the present invention are exhibited. For example, in the above example, the mouthpiece body is formed in a substantially cylindrical shape, but may be formed in other various shapes such as a polygonal shape. In addition, the mouthpiece body 30 is composed of two molded parts, but may be composed of one part, or may be composed of three or more parts.
