Party popper

Abstract

A party popper contains: a cylinder, a sealing element, a drive element, a flexible fitting element, and a weaken structure. The cylinder includes a first segment and a second segment. The sealing element is a film and is configured to close the second segment. The multiple streamers are filled in the cylinder. A diameter of the drive element is equal to a diameter of the cylinder. The flexible fitting element is made of flexible material with low elastic modulus, and the flexible fitting element includes a cap, a neck section, and a head. The weaken structure surrounds the neck section, and a pulling length is defined to pull off the weaken structure by pulling the weaken structure from the head to the neck section and the cap, such that the weaken structure is pulled off to remove the neck section and the head from the cap.

What is claimed is: 
     
         1 . A party popper comprising:
 a cylinder including a first segment and a second segment, the first segment having an opening, and the second segment having an opening;   a sealing element being a film, fixed on the second segment of the cylinder, and configured to close the opening of the second segment;   multiple streamers filled in the cylinder;   a drive element, a diameter of the drive element being equal to a diameter of the cylinder, and the drive element being received in the opening of the first segment of the cylinder;   a flexible fitting element made of flexible material with low elastic modulus, the flexible fitting element including a cap, a neck section, and a head, wherein the cap closes the opening of the first segment, the neck section is formed around a center of the cap, and the head is formed on a top of the neck section, wherein a diameter of the head is more than a diameter of the neck section;   a weaken structure surrounding the neck section, wherein a pulling length is defined to pull off the weaken structure by pulling the weaken structure from the head to the neck section and the cap, such that the weaken structure is pulled off to remove the neck section and the head from the cap.   
     
     
         2 . The party popper as claimed in  claim 1 , wherein the neck section has an orifice defined thereon and passing through the cap. 
     
     
         3 . The party popper as claimed in  claim 1 , wherein the flexible fitting element includes an extension which is formed around the peripheral side of the cap, and the extension is covered around the first segment of the cylinder. 
     
     
         4 . The party popper as claimed in  claim 3 , wherein the cylinder includes a groove surrounding an outer wall thereof, and the extension has a flange extending around and engaged with the groove. 
     
     
         5 . The party popper as claimed in  claim 1 , wherein a length L1 is defined between the cap and the head while not pulling the head, wherein a ratio of L1:L2≈1:10. 
     
     
         6 . The party popper as claimed in  claim 1 , wherein the sealing element is a film made of foam. 
     
     
         7 . The party popper as claimed in  claim 1 , wherein the drive element is a foam sheet.
