Party Popper

Abstract

Provided 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.

1 . 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 said explosive charge and said discharge port are accommodated, and said discharge port of said cylindrical body is closed by a lid member that is push-opened by said launchable objects discharged toward said discharge port upon receiving a blast generated by explosion of said explosive charge,
 wherein   said party popper comprises:   a front-open launchable object container bag to be filled with said launchable objects, which launchable object container bag is arranged on the front side of said explosive charge inside said cylindrical body and installed in such a manner to tightly seal said discharge port by integrally bonding the front-side opening margin of said bag to the margin of said discharge port of said cylindrical body; and   a movable pressure receiver movable in the axial direction of said cylindrical body between said launchable object container bag and said explosive charge, which movable pressure receiver comprises: a pressure-receiving part formed on the side of said launchable object container bag in said axial direction; and a peripheral wall that stands from said pressure-receiving part toward said explosive charge and has a cross-sectional shape conforming to the inner peripheral shape of said cylindrical body, and is not connected to any member constituting said party popper,   said movable pressure receiver, upon receiving a pressure from said blast, moves inside said cylindrical body toward said discharge port,   a pressure is applied to the bottom part of said launchable object container bag by said pressure-receiving part and this causes said launchable object container bag to expand while being inverted, as a result of which said movable pressure receiver and said launchable objects are pushed out of said cylindrical body, and   said movable pressure receiver thus pushed out of said cylindrical body is stored in the thus inverted launchable object container bag.   
     
     
         2 . The party popper according to  claim 1 , wherein
 said peripheral wall has a shape that is slightly inclined inwardly toward said pressure-receiving part, and   a protruding part which protrudes outwardly is formed on the opening side of said peripheral wall.   
     
     
         3 . The party popper according to  claim 1 , wherein said movable pressure receiver is formed from a resin. 
     
     
         4 . The party popper according to  claim 2 , wherein said movable pressure receiver is formed from a resin.
