Definitions

• the technical field of the invention is in the dynamics of plastic articles or hard rubber.
• the invention is a new piece employed in a party item already known.
• the party item contains chemicals which provide the dynamic energy to the invention.
• Much of the material ejected by the launcher are secondary products consisting of pyrotechnical detritus, bits of paper and the cardboard used in the interior.
• the flexible barrier for a confetti or streamer launcher is made of one piece. It replaces the circular cardboard that separates the streamers from the pyrotechnical mixture in the interior of the launcher.
• the invention has a bowl shape. It is characterised by having a base resistant to rupture but flexible and capable of deformation and a ring that forms the rim of the bowl.
• the ring is more rigid and has zones for incorporating a thread and or an adhesive in order to provide a strong and hermetic fix with the body of the launcher.
• the body of the launcher has a thread or corresponding zone to facilitate the coupling.
• the invention may work using an interior or exterior zone of the body for its coupling.
• the thread would be situated on the exterior of the ring.
• the ring would have a shapelike the rim of a hat that would be wider in diameter than the body giving this surface access to the exterior of the body for fixing.
• a cardboard top covers the aperture of the bowl and maintains the material in the bowl but does not impede its ejection during activation. It is foreseen that it may be fixed by a strap so that it is not ejected during activation.
• a sealed and resistant chamber is thus formed in the interior of the launcher, between the neck of the bottle where the pyrotechnical mixture is situated and the base of the bowl.
• the pyrotechnical mixture is activated, by pulling the string, the gases produced cannot escape and deform the base of the bowl. The deformation ejects the contents of the bowl.
• the smoke and the gases are contained in the chamber by the body of the bottle and the flexible barrier forming the base of the bowl.
• the residual solids of the pyrotechnics are contained in their entirety.
• the invention does not eject cardboard plugs since it replaces the loose cardboard in the interior and it is easy to impede the ejection of the cardboard that forms the top by using a strap.
• Fig 1 Shows a view of the body with a bottle shape and an internal thread and the invention, separate, with a corresponding exterior thread.
• Fig 2 Shows the invention coupled to the body.
• Fig 3 Shows a longitudinal section of the artefact and invention coupled before activation of the pyrotechnical mixture with streamers as the material to be launched.
• Fig 4 Shows a longitudinal section of the artefact and invention after the activation of the pyrotechnical mixture.
• Fig 5 Shows a longitudinal section of the article object of this invention.
• the body with a bottle shape (1) contains the pyrotechnical mixture rolled in paper (2) and in contact with the activation string (3).
• the string passes through the body via a narrow hole that penetrates the body (1) at its end.
• the body (1) has an internal coupling zone (4) which corresponds with the zone of rigid coupling (5) of the invention (6).
• the contact and fixing, resitent to rupture, permits a hermetic barrier.
• the invention has a piece (6) with the form of a bowl. It can be composed of common plastic with characteristics that when it is thick it forms rigid structures but on diminishing its thickness it displays flexibility.
• the invention is (6) is thicker in the more rigid zones used for coupling and is less thick at its flexible base (7).
• the exterior top (8) is placed over the opening of the invention in such a manner that it does not offer resistance when it is subjected to pressure from the interior of the artefact; connecting the top (8) and the invention (6) there is a small strap (10).
• Streamers (9) are placed in the interior of the invention (6).
