AI Technical Summary

Benefits of technology

The invention provides a waste receptacle that prevents toxic gases from escaping into the working environment. The receptacle has an exterior wall and an interior receptacle for receiving a bag. It also has an interior bag closure mechanism that can be operated from the exterior of the receptacle. The receptacle can be equipped with an exhaust hood and an exhaust system to efficiently remove waste. The invention also includes a rotator assembly that can close a flexible bag by rotating its upper open end.

Problems solved by technology

Many industries generate toxic waste.
When such toxic waste materials are stored in conventional trash cans, toxic gases are produced in the trash can interior and released when the cover of the trash can is opened.
The toxic gas emitted from the trash can escapes into the working environment and can be harmful to custodial and other personnel within the area.
Such introduction of toxic materials into the working environment can result in serious illnesses and other maladies.
Additionally, these toxic contaminants that escape into the working environment can also contaminate and destroy the products being manufactured in the area.
Using conventional trash receptacles, these toxic contaminants can diffuse into the work environment and cause corrosion and other failure mechanisms to occur on the semiconductor devices and substrates present in the working environment.

Embodiment Construction

[0018]FIG. 1 is a cross-sectional view showing an exemplary waste receptacle according to the invention. Waste receptacle 3 includes tank portion 5 and exhaust hood portion 7 disposed above tank portion 5. Tank portion 5 includes double walls 9. Double walls 9 include outer tank wall 11 and inner tank wall 13. Gap 15 is formed between outer tank wall 11 and inner tank wall 13. In an exemplary embodiment, the waste receptacle is cylindrical such that outer tank wall 11 is cylindrical and inner tank wall 13 is cylindrical and gap 15 forms an annular space therebetween. Waste receptacle 3 further includes bottom 17 and cover 19.

[0019] Exhaust hood portion 7 includes outer wall 21 and vented, or gas-permeable inner wall 23 that includes openings 25 in the exemplary embodiment. Outer wall 21 and outer tank wall 11 combine to form a substantially continuous exterior wall of waste receptacle 3. Exhaust hood portion 7 and tank portion 5 combine to form can 27 that includes upper lip 29.

Abstract

A toxic waste receptacle with a cover includes an exhaust hood that exhausts toxic gases from the waste receptacle and an interior bag closure mechanism that is operable externally and closes the bag disposed within an interior receptacle of the toxic waste receptacle. The exhaust system exhausts toxic gases from the interior of the waste receptacle and the internal bag closure mechanism confines harmful toxic gases within the bag prior to opening the cover of the waste receptacle to prevent toxic gases from escaping into the work environment.

Description

FIELD OF THE INVENTION [0001] This invention is directed to a receptacle for toxic waste. More particularly, the invention is directed to a toxic waste receptacle that includes an internal bag closure mechanism that is operable from outside the waste receptacle. BACKGROUND [0002] Various types of trash cans and other waste receptacles that use disposable liners, are widely used in various industries. Conventional trash cans include a cover disposed to seal the open end of the receptacle and a flexible bag or liner disposed in the receptacle. The flexible bags are commonly made of impervious materials such as plastic. The conventional method for handling industrial trash is to open the cover of the trash can and dispose trash within the open bag that is positioned within the trash can. When the bag is full, the cover is again opened and the open bag is removed by custodial or other personnel who must then manually close the bag to package the waste it contains. [0003] Many industries...
