## Title
Suction free waste receptacle apparatus

## Abstract

A suction free waste receptacle apparatus provided in a plurality of embodiments, the apparatus providing suction relief whereby a flexible trash bag suction to the apparatus is negated, thereby affording easier bag placement and removal from the apparatus. The apparatus prevents spillage of trash and liquids from a leaking bag. The apparatus combines rigidity with light weight using a reinforcing rib structure.

## Background
BACKGROUND OF THE INVENTION
Removing a trash bag from a typical trash usually confronts the user with suction developed between the bag and the trash can which the bag temporarily resides within. The suction developed resists removal of the trash bag. Removal of the trash bag then often becomes a two-person endeavor, with one holding the can and one pulling the bag. Torn trash bags and spills are not unusual. Various methods of solving the problem have also met with difficulties. As example of the difficulties encountered, trash material and especially liquids often spill from torn bags within the trash can, when such cans offer breathing directly to the exterior of the can. Bags often leak and fail, and suction relief holes which provide trash material and liquid escape are not desirable. A new approach is needed in a trash can apparatus that provides for easy removal of trash bags.
FIELD OF THE INVENTION
The suction free waste receptacle apparatus relates to trash cans and waste receptacles and more especially to a suction free waste receptacle apparatus which provides easier trash bag insertion and removal.
DESCRIPTION OF THE PRIOR ART
Prior related art U.S. Pat. No. 5,690,247 issued to Boover on Nov. 25, 1997 teaches a wastebasket for removing and retaining a trash can liner which provides openings from the inside of the wastebasket to the outside, thereby inviting transfer of spills within the wastebasket to the outside of the wastebasket. The device does not provide the support and suction relief as is offered by the present apparatus. U.S. Pat. No. 4,416,197 issued to Kehl on Jan. 22, 1983 teaches a waste material compactor which provides holes completely through the side walls. The apparatus thereby provides the opportunity for leaking from the container. U.S. Pat. No. 4,905,945 issued to Peterson on Mar. 6, 1990 teaches a refuse can stabilizing apparatus which supports a refuse can. While providing a can support, the device is not designed to offer the suction free waste receptacle of the present apparatus.
While the above-described devices fulfill their respective and particular objects and requirements, they do not describe a suction free waste receptacle apparatus that provides for the advantages of the present suction free waste receptacle apparatus. In this respect, the present suction free waste receptacle apparatus substantially departs from the conventional concepts and designs of the prior art. Therefore, a need exists for an improved suction free waste receptacle apparatus.
SUMMARY OF THE INVENTION
The general purpose of the suction free waste receptacle apparatus, described subsequently in greater detail, is to provide a suction free waste receptacle apparatus which has many novel features that result in an improved suction free waste receptacle apparatus which is not anticipated, rendered obvious, suggested, or even implied by prior art, either alone or in combination thereof. To attain this, the suction free waste receptacle apparatus
To attain this the apparatus is provided in more than one embodiment. Each embodiment comprises a vessel with a plurality of ventilation openings proximal to a bottom of the vessel. The first embodiment is a one-piece apparatus. The first embodiment provides a vessel with externally disposed ribs. Each rib further comprises a tube within. Each tube has an upper opening venting to the atmosphere. Each tube further comprises a lower opening which passes through the outer wall surface and the inner wall surface of the vessel. Each tube opening is disposed proximal to the bottom of the vessel. Each rib to vessel juncture is twice reinforced with opposing angles. Allowing the bottom of the vessel to breath freely to the atmosphere negates suction and pressure and provides for easy removal and installation of a flexible trash bag within the apparatus. The ribs also strengthen the vessel.
An added embodiment of the apparatus provides a two-piece construction. The vessel is open at both top and bottom. The bottom of the vessel is provided with a plurality of lower openings through the outer wall surface and the inner wall surface. The bottom of the vessel removably rests within the base provided. The base is of a diameter larger than the vessel. The base has a height which preferably exceeds the height of the lower openings of the vessel.
Yet another embodiment of the apparatus provides a one-piece construction with a base having a diameter greater than the vessel and a height. The base is joined to the vessel at the bottom of the vessel. The base is also preferably reinforced with a lip at a top of the height of the base. The vessel is provided with a plurality of openings at a height of the vessel whereby the lower openings are lower than the base height.
All embodiments of the apparatus provide for potential trash bag leaks. Rather than broken or leaking bag spilling trash bag contents, each embodiment of the apparatus contains any such spills.
Thus has been broadly outlined the more important features of the improved suction free waste receptacle apparatus so that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.
An object of the suction free waste receptacle apparatus is to provide suction free removal of trash bags from the receptacle.
