Ashtray

Abstract

An ashtray includes a peripheral wall and a bottom wall together defining a compartment. A sealing plate having a melting point below 200° C. is mounted to an inner periphery of the peripheral wall and separates the compartment into an open space and a sealed space. A burning cigarette can burn through the sealing plate such that a burning end of the cigarette can enter the sealed space that lacks oxygen. Thus, the cigarette can be put out immediately to avoid injury to the human body.

1 . An ashtray comprising:
 a peripheral wall and a bottom wall together defining a compartment; and   a sealing plate mounted to an inner periphery of the peripheral wall and separating the compartment into an open space and a sealed space, with the sealing plate having a melting point below 200° C.   
   
   
       2 . The ashtray as claimed in  claim 1 , with the sealing plate being mounted to the inner periphery of the peripheral at a level in a range from one half to one-third of a height from a bottom to a top of the peripheral wall.
