Definitions

• the technical sector of the invention is that of the dynamics of plastic or hard rubber articles.
• the invention is a new piece used in an already known party article.
• the party article contains chemistry that produces energy by providing dynamics to the invention.
• Serpentine and confetti launchers that use a quantity of pyrotechnic mixture are known. They are known in some countries by the name "Party Poppers n .
• the flexible barrier device for throwers of streamers or confetti is composed of one piece. Replace the cardboard circle that separates the streamers from the pyrotechnic mixture inside the pitcher.
• the invention is in the form of a bowl. It is characterized by having a base resistant to rupture but flexible and capable of deforming and a ring that forms the edge of the bowl.
• the ring is more rigid and has areas to incorporate a thread and or adhesive for a strong and hermetic fixation with the casing of the caster.
• the housing has a thread or corresponding area to facilitate coupling. ⁇ It is envisioned that the invention works by using an inner or outer area of the housing for coupling.
• the thread is located on the outside of the ring.
• the ring is shaped like a hat edge that exceeds the diameter of the housing giving its surface access to the outside of the housing for fixing.
• the material to be thrown is placed inside the bowl.
• a cardboard cap covers the opening of the bowl and keeps the material held in the bowl but does not prevent its expulsion during initiation. It is planned to fix it with a strap to the invention so that it does not come out during initiation.
• a sealed and resistant chamber is then formed inside the launch, between the neck of the bottle where the pyrotechnic mixture is located and the base of the bowl. When the pyrotechnic mixture starts in this chamber, stretching the cord, the gases cannot escape and deform the base of the bowl. The deformation expels the contents of the bowl. ⁇ Smoke and gases are contained in the chamber by the bottle housing and the flexible barrier that forms the base of the bowl. Solid waste from pyrotechnics is completely contained. The invention does not eject cardboard caps since
