FIELD OF THE INVENTION
The present invention relates to trash containers and more particularly to a trash container having flexible walls.
BACKGROUND
Trash is a common problem around the home, office and outdoors. In order to collect this trash, trash cans have been used. However, these trash cans can be small and generally have rigid sidewalls. The rigid sidewalls prevent the trash cans from being flattened out and stored in a relatively small space. What is needed is a trash can which can be easily deployed and easily stored in a limited space.
SUMMARY
A trash container for holding trash may include an inflatable frame, a front flexible wall connected to the inflatable frame, a back flexible wall connected to the inflatable frame and opposed to the front flexible wall and a pair of side flexible walls connected to the inflatable frame and connected to the front flexible wall and the back flexible wall.
The trash container may include a rigid bottom wall.
The trash container may include a tie down strap.
The trash container may include an inflator/deflator device including a valve to inflate and deflate the frame of the trash container.
The trash container may include a release valve.
The trash container may include a cleat.
The bottom wall may be inclined at an angle between 1° and 90° with respect to a support surface.
A bench support system is placed under the inclined wall for a pet.

Referring back to FIGS. 1 and 2 collectively, a trash container 100 is illustrated that comprises an inflatable frame. Generally, the inflatable frame 109 comprises a plurality of vertical inflatable, tubular vertical members (four of the substantially vertical members 115) extending normally from a bottom wall 107. For example, the plurality of vertical inflatable, tubular vertical members includes four top periphery members, such as top periphery member 113, which are arranged in a rectangular configuration. The inflatable frame 109 also comprises a plurality of bottom frame members. For example, four bottom periphery members, such as bottom periphery member 111 can be arranged into a rectangular configuration. The bottom periphery members 111 are associated with the bottom wall 107 in some embodiments, and can be coupled with the plurality of vertical inflatable, tubular vertical members. According to some embodiments, plurality of bottom frame members (four of the bottom periphery members 111) are inflatable.
Also, the plurality of upper frame members (four of the top periphery members 113) can also couple with the plurality of vertical inflatable, tubular vertical members 115. The plurality of upper frame members 113 are inflatable and arranged to form an opening of an enclosure. For example, the plurality of upper frame members 113 define the opening of the trash container 100.
In some embodiments, the plurality of vertical inflatable, tubular vertical members 115, plurality of bottom frame members 111, and plurality of upper frame members 113 are arranged to form openings. According to some embodiments, a plurality of flexible wall panels, such as wall panel 105 are associated with the openings to form the enclosure.
In some embodiments, the plurality of vertical inflatable, tubular vertical members 115, plurality of bottom frame members 111, and plurality of upper frame members 113 are interconnected together in fluid communication.

The rows of slits 163 are offset from one another in some embodiments.
In accordance with the present disclosure, the trash container 100 can include a mat 150 that extends across the bottom wall 107. The bottom wall 107 has triangular sidewalls that cooperate with a back sidewall, as well as the mat 150 to create an example wedge member. In some embodiments, the mat is absorbent and configured to absorb liquids.
As illustrated in FIGS. 10-15, the bottom wall 107 can be inclined relative to the ground and forms a cavity with the plurality of bottom frame members. In some embodiments, one or more support plates, such as support plate 167 (see FIGS. 12 and 12A), extend between the plurality of bottom frame members and the inclined bottom wall 107. The one or more support plates are inflatable in some instances.
In additional embodiments, the bottom wall 107 is inclined and supported at opposing ends with inflatable floor supports, such as inflatable floor supports 169 illustrated in FIG. 15. These supports are disposed at the corners of the bottom wall 107, as an example configuration.
Some embodiments include cylindrical inflatable supports, such as in FIG. 26. In these embodiments, one of the plurality of bottom frame members, such as frame member 1902 can be enlarged to form a back cylinder support such that the bottom wall 1903 is inclined when coupled with the bottom frame members (1901 and 1902).
Some embodiments, such as trash containers of FIGS. 27-29 include inflatable cylindrical rings, such as a bottom periphery member 16/11 of FIG. 27. A plurality of vertical inflatable, tubular vertical members (such as 16/15) are coupled to the inflatable ring 16/11.
In some embodiments, an upper frame ring 16/13 is included and is also inflatable. The upper frame ring 16/13 forms an opening of an enclosure. Wall panels and an inflation/deflation device can be included as well. In some embodiments, the inflation/deflation device comprises an adjustable valve.
In some embodiments, a bottom wall has a support area and a plurality of pie wedge sections 107 that are angled downwardly away from the support area. A portion of the plurality of pie wedge sections can comprise slits or holes 163/161 for providing fluid communication from inside the enclosure.
The trash container can include a support area 007. The support area and the plurality of pie wedge sections are spaced apart from the lowest floor to form a space. In some embodiments, a liquid absorbing material is disposed in the space.
