  • the launchable object container bag 47 is configured such that, upon receiving a blast generated by the explosive charge 44 , it expands while being inverted and protrudes from the discharge port 48 ; therefore, by this action, the launchable objects 46 are launched faraway while being dispersed at a wide angle and, in association with this inverting action of the launchable object container bag 47 , scattering of the launchable objects 46 (e.g., confetti) that are directly subjected to a swirling force and discharged is promoted, so that an effect of presenting a more spectacular scene is attained.
  • the launchable objects 46 e.g., confetti
  • An object of the present invention is to provide a party popper which, with a small amount of explosive, can realize presentation of a more spectacular scene by launching launchable objects faraway while allowing the objects to disperse at a wide angle in the air.
  • the party popper of the present invention is a party popper in which, inside of a cylindrical body having a discharge port at the front end, an explosive charge to be exploded by an operation of pulling a pull string and launchable objects arranged between the explosive charge and the discharge port are accommodated, and the discharge port of the cylindrical body is closed by a lid member that is push-opened by the launchable objects discharged toward the discharge port upon receiving a blast generated by explosion of the explosive charge,
  • the party popper comprises:
  • a front-open launchable object container bag to be filled with the launchable objects, which launchable object container bag is arranged on the front side of the explosive charge inside the cylindrical body and installed in such a manner to tightly seal the discharge port by integrally bonding the front-side opening margin of the bag to the margin of the discharge port of the cylindrical body;
  • a movable pressure receiver movable in the axial direction of the cylindrical body between the launchable object container bag and the explosive charge
  • which movable pressure receiver comprises: a pressure-receiving part formed on the side of the launchable object container bag in the axial direction; and a peripheral wall that stands from the pressure-receiving part toward the explosive charge and has a cross-sectional shape conforming to the inner peripheral shape of the cylindrical body, and is not connected to any member constituting the party popper,
  • the movable pressure receiver upon receiving a pressure from the blast, moves inside the cylindrical body toward the discharge port,
  • a pressure is applied to the bottom part of the launchable object container bag by the pressure-receiving part and this causes the launchable object container bag to expand while being inverted, as a result of which the movable pressure receiver and the launchable objects are pushed out of the cylindrical body, and
  • the movable pressure receiver thus pushed out of the cylindrical body is stored in the thus inverted launchable object container bag.
  • the launchable object container bag can be surely inverted and allowed to expand; therefore, the launchable objects can be launched faraway while being dispersed at a wide angle in the air, and presentation of a more spectacular scene can thus be realized with a small amount of explosive.
  • the movable pressure receiver gets stored in the inverted launchable object container bag, the movable pressure receiver is not released into the air along with the launchable objects.
  • the movable pressure receiver is allowed to move to the position of the bottom part of the inverted launchable object container bag by not connecting the movable pressure receiver with any of the members constituting the party popper, the moving distance of the movable pressure receiver can be increased, so that a pressure can be applied to the launchable objects over a longer period of time.
  • the party popper of the present invention is also characterized in that the peripheral wall has a shape that is slightly inclined inwardly toward the pressure-receiving part and a protruding part which protrudes outwardly is formed on the opening side of the peripheral wall.
  • the air resistance during the movement of the movable pressure receiver through the cylindrical body can be reduced.
  • the gap between the inner wall surface of the cylindrical body and the outer surface of the peripheral wall is reduced by forming the protruding part on the peripheral wall, the movable pressure receiver is allowed to move straight without losing the blast pressure as much as possible.
  • the party popper of the present invention is characterized in that the movable pressure receiver is formed from a resin.
  • presentation of a more spectacular scene can be realized with a small amount of explosive by launching launchable objects faraway while allowing the objects to disperse at a wide angle in the air.

  • FIG. 2 is a cross-sectional view illustrating a post-discharge state of the party popper.
  • a party popper 2 comprises: a cylindrical body 3 ; an explosive charge 4 ; a movable pressure receiver 5 ; launchable objects 6 ; and a launchable object container bag 7 .
  • the cylindrical body 3 is a tube-shaped or polygonal-shaped cylindrical member made of a cardboard, a plastic or the like, in which a discharge port 8 is formed at the front end and a holding part 10 is arranged on the rear side.
  • a front-end protruding part 12 a of an exterior paper 12 wrapped on the outer surface of the cylindrical body 3 is utilized as a lid member 14 , and the discharge port 8 is closed by folding the lid member 14 toward the discharge port 8 in an overlapping manner.
  • the explosive charge 4 is so-called “pull-cap” which is exploded by an operation of pulling a pull string 16 , and the explosive charge 4 is installed in such a manner to be received by an explosive charge-receiving plate 18 .
  • the pull string 16 passed through the explosive charge 4 extends from the explosive charge-receiving plate 18 to the rear side of the cylindrical body 3 .
  • the movable pressure receiver 5 is a closed-bottom cylindrical resin member which is arranged in the cylindrical body 3 between the launchable object container bag 7 and the explosive charge 4 in a state of being movable along the axial direction.
  • the movable pressure receiver 5 comprises: a pressure-receiving part 5 a which is formed on the side of the launchable object container bag in the axial direction; a peripheral wall 5 b which stands from the periphery of the pressure-receiving part 5 a toward the explosive charge; and a cylindrical space 5 c which is surrounded by the peripheral wall 5 b and the pressure-receiving part 5 a , and a protruding part 5 d which protrudes toward the outer side of the space 5 c is formed on the opening side of the peripheral wall 5 b .
  • the peripheral wall 5 b is configured to have a tubular or polygonal cylindrical shape in conformity with the shape of the cylindrical body 3 and slightly inclined inwardly toward the pressure-receiving part 5 a .
  • the movable pressure receiver 5 is not connected with any of the members constituting the party popper 2 , such as the explosive charge-receiving plate 18 , by a connecting member such as a string. It is preferred that the movable pressure receiver 5 be configured to have a height (H) of 20 mm to 25 mm.
  • the launchable objects 6 are composed of confetti, streamers and the like and loaded into the launchable object container bag 7 . Prior to the use, since the mouth of the launchable object container bag 7 is also closed by the lid member 14 that closes the discharge port 8 of the cylindrical body 3 , the launchable objects 6 do not spill out of the launchable object container bag 7 .
  • the launchable object container bag 7 is a front-open bag made of, for example, a vinyl chloride resin film or sheet or a thin cloth, which has excellent softness and flexibility and is not torn even by the pressure of a blast generated by explosion of the explosive charge 4 .
  • the launchable object container bag 7 is accommodated on the front side of the explosive charge 4 .
  • a bag opening margin 7 a on the front side of this launchable object container bag 7 is folded back on the outer circumference of the discharge port 8 of the cylindrical body 3 , and the outer circumference of the thus folded bag opening margin 7 a is pressed against the outer circumference of the cylindrical body 3 by the exterior paper 12 and integrally bonded to an discharge port margin 48 a .
  • This configuration enables to attain a state where the launchable object container bag 7 is installed in such a manner that it tightly seals the discharge port 8 and is not detached from the discharge port margin 48 a even when a blast pressure generated by explosion of the explosive charge 4 is applied thereto.
  • the party popper 2 configured in this manner is held by holding the holding part 10 of the cylindrical body 3 with one hand and, when the pull string 16 is pulled by the other hand to cause explosion of the explosive charge, a blast generated by the explosion makes the movable pressure receiver 5 to move vigorously through the cylindrical body 3 toward the discharge port 8 .
  • a bottom part 7 b of the launchable object container bag 7 is pushed by the pressure-receiving part 5 a of the movable pressure receiver 5 , and the launchable object container bag 7 is thereby inverted.
  • the launchable objects 6 are pushed and the lid member 14 is push-opened by the launchable objects 6 , whereby the launchable objects 6 are vigorously ejected from the discharge port 8 into the air.
  • the bottom part 7 b of the launchable object container bag 7 continues to be pushed by the pressure-receiving part 5 a of the movable pressure receiver 5 , as a result of which the launchable object container bag 7 expands and protrudes while being inverted.
  • the launchable object container bag 7 since the bag opening margin 7 a of the launchable object container bag 7 is integrally bonded to the discharge port margin 8 a , the launchable object container bag 7 is not detached from and thus does not fly out of the cylindrical body 3 .
  • the launchable objects 6 When the launchable object container bag 7 expands while being inverted, the launchable objects 6 are launched in such a manner to spread at a wide angle in all directions. Particularly, since the launchable objects 6 such as confetti are discharged by being directly subjected to the inverting action of the launchable object container bag 7 , scattering of the launchable objects 6 is promoted, so that the effect of presenting a scene is further enhanced.
  • the movable pressure receiver 5 is caught and stopped by the bottom part 7 b of the launchable object container bag 7 and thereby prevented from moving any further.
  • the movable pressure receiver 5 whose movement is thus stopped gets stored in the launchable object container bag 7 without being discharged into the air.
  • the launchable object container bag 7 is surely inverted and expanded by the movement of the movable pressure receiver 5 formed in conformity with the shape of the cylindrical body 3 caused by a blast pressure, the launchable objects 6 can be launched faraway while allowing them to disperse at a wide angle in the air, so that presentation of a more spectacular scene can be realized with a small amount of explosive.
  • the movable pressure receiver 5 since the frictional force generated between the peripheral wall 5 b and the inner peripheral wall of the cylindrical body 3 is reduced by constituting the movable pressure receiver 5 with a resin member, the movable pressure receiver 5 is allowed to move smoothly in the cylindrical body 3 . In addition, by processing the movable pressure receiver 5 to have a closed-bottom cylindrical shape, the weight of the movable pressure receiver 5 can be reduced.
  • the gap between the inner wall surface of the cylindrical body 3 and the outer wall surface of the peripheral wall 5 b is reduced and leakage of the blast to the outside of the space 5 c can thereby be prevented; therefore, the blast can be concentrated in the space 5 c , so that the movable pressure receiver 5 is allowed to move straight without losing the blast pressure as much as possible.
  • the peripheral wall 5 b is slightly inclined inwardly toward the pressure-receiving part 5 a , the air resistance during the movement of the movable pressure receiver 5 through the cylindrical body 3 can be reduced.
  • the pressure-receiving part 5 a may be configured to have, for example, a cupular shape.
  • the movable pressure receiver 5 can be stabilized and its movement in straight line can be enhanced and, by controlling the height (H) of the movable pressure receiver 5 to be 25 mm or less, the weight of the movable pressure receiver 5 can be reduced.
  • the connecting member may interfere with the movement of the movable pressure receiver 5 ; however, such a problem does not occur as long as the movable pressure receiver 5 is not connected to any of the members constituting the party popper 2 .
  • the movable pressure receiver 5 is allowed to move to the position of the bottom part 7 b of the completely inverted launchable object container bag 7 ; therefore, the moving distance of the movable pressure receiver 5 can be increased, so that a pressure can be applied to the launchable objects 6 for a longer period of time.
  • a single cotton ball of about 20 mm in diameter was used in place of the launchable objects 6 such as confetti and streamers.
  • the measurement was performed by visually determining the distance of the first landing point of the cotton ball from the party popper. It is noted here that a flying distance of “0” indicates that the cotton ball was not discharged from the discharge port.
  • Example 1 as illustrated in the pattern A of FIG. 3 , the projectile measurement test was performed using a party popper of the pattern A, which is the party popper according to the present embodiment.
  • the flying distance of the cotton ball was measured to be 400 to 890 cm, and it was thus found that a long flying distance can be stably ensured with the use of the party popper of the pattern A.
  • the party popper of the pattern A was slightly different from the party popper 2 described in the present embodiment in that a rod-shaped member was attached to the movable pressure receiver.
  • the center of the gravity of the movable pressure receiver can be emphasized during the movement of the movable pressure receiver in the axial direction, so that the straightness of the movement of the movable pressure receiver can be enhanced.
  • Example 2 as illustrated in FIG. 3 , the projectile measurement test was performed using a party popper of the pattern B, which is one of the party poppers according to other embodiments.
  • the party popper of the pattern B is the party popper of the pattern A whose movable pressure receiver was connected with the explosive charge-receiving plate by a connecting string.
