Disposable Ashtray

Abstract

A disposable ashtray includes a body made of paper and having a compartment with a top opening for receiving cigarette butts. The annular wall includes an annular flange extending outward from a top thereof. A heat-resisting layer covers an inner face defining the compartment. A top cover is mounted on the top of the annular wall. The top cover includes a crown having a central hole. The crown includes a plurality of cigarette receiving grooves. The crown further includes an annular wall extending downward from an outer peripheral edge thereof. The annular wall has an inner diameter slightly larger than an outer diameter of the annular flange. A plurality of protrusions extend inward from a lower edge of the annular wall. A first engaging groove is defined between each protrusion, the crown, and the annular wall. The annular flange is engaged in the engaging grooves.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to an ashtray and, more particularly, to a disposable ashtray.[0002]Conventional ashtrays generally made of glass, rigid plastic, metal or ceramic material are expensive and, thus, not discarded immediately after use. Furthermore, conventional ashtrays can not be compressed to reduce the volume and are, thus, not suitable for use in the outdoors or vehicles. Further, smokers in public places often throw the cigarette butts onto the ground when no ashtray is near, leading to environmental pollution and risk of fire. However, carriage and cleaning of ashtrays is not convenient. Furthermore, cleaning of ashtrays for some places such as hotels, resorts, restaurants, etc. requires intensive labor.[0003]Thus, a need exists for an inexpensive ashtray that can be discarded immediately after use.BRIEF SUMMARY OF THE INVENTION[0004]The present invention solves this need and other problems in the field of ashtrays by providing, in ...

AI Technical Summary

Benefits of technology

[0005]In the most preferred form, the crown of the top cover includes a top face above the central opening. The top face includes the outer peripheral edge. The crown further includes an inclined face extending downward from an inner peripheral edge of the top face toward the central opening. The cigarette receiving grooves are annularly spaced from one another and extend into the inclined face. Furthermore, each cigarette receiving groove includes an inner end and an outer end having a spacing to the central opening larger than the inner end. The inner end has a spacing to the top face of the crown larger than the outer end. The annular wall further includes a plurality of second protrusions extending inward from the lower edge thereof. The second protrusions are annularly spaced from one another and spaced from the first protrusion. A second engaging groove is defined between the crown, the annular wall, and each second protrusion. The annular flange is engaged in the second engaging grooves. Each of the first and second protrusions abuts against a lower edge of the annular flange. The annular wall further includes an annular extension extending outward from the lower edge of the annular wall away from the crown and away from the annular wall. The annular extension has an inner diameter larger than that of the top opening. The annular extension can be gripped by a user to allow easy removal of the top cover from the body.

Problems solved by technology

Conventional ashtrays generally made of glass, rigid plastic, metal or ceramic material are expensive and, thus, not discarded immediately after use.

Furthermore, conventional ashtrays can not be compressed to reduce the volume and are, thus, not suitable for use in the outdoors or vehicles.

Further, smokers in public places often throw the cigarette butts onto the ground when no ashtray is near, leading to environmental pollution and risk of fire.

However, carriage and cleaning of ashtrays is not convenient.

Furthermore, cleaning of ashtrays for some places such as hotels, resorts, restaurants, etc. requires intensive labor.
