Flotation device

Abstract

A flotation device includes a hollow body, a container attached to the hollow body and comprising a nozzle extending into the hollow body, and a latching member formed at the hollow body to attach the hollow body to an object requiring flotation. The hollow body and the container respectively contain two chemical materials, such that when the container is pressed, it ejects material therefrom via the nozzle into the hollow body, whereby the material from the container reacts with the material in the hollow body to produce a gas to inflate the hollow body.

1 . A flotation device comprising:
 a hollow body;   a container attached to the hollow body and comprising a nozzle extending into the hollow body; and   a latching member formed at the hollow body to attach the hollow body to an object requiring flotation;   wherein the hollow body and the container respectively contain two chemical materials, such that when the container is pressed, it ejects material therefrom via the nozzle into the hollow body, whereby the material from the container reacts with the material in the hollow body to produce a gas to inflate the hollow body.   
     
     
         2 . The flotation device of  claim 1 , wherein the latching member comprises a grommet and a latching tape, respectively formed at the two opposite ends of the hollow body. 
     
     
         3 . The flotation device of  claim 2 , wherein latching tape is a self-adhesive latching tape. 
     
     
         4 . The flotation device of  claim 1 , wherein at least one of the chemical materials is carbonic acid material to produce carbon dioxide gas. 
     
     
         5 . The flotation device of  claim 4 , wherein the hollow body contains weak acid powder, and the container contains alkaline solution. 
     
     
         6 . The flotation device of  claim 5 , wherein the weak acid powder is oxalic acid powder, and the alkaline solution is sodium bicarbonate solution. 
     
     
         7 . The flotation device of  claim 4 , wherein the hollow body contains alkaline powder, and the container contains weak acid solution. 
     
     
         8 . The flotation device of  claim 7 , wherein the weak acid powder is sodium bicarbonate powder, and the alkaline solution is oxalic acid solution. 
     
     
         9 . The flotation device of  claim 1 , wherein the hollow body and the container are made of elastic materials.
