Abstract

A includes a main body portion defining a waste holding chamber, a vent path extending from the waste holding chamber to atmosphere, and a float member. The float member is coupled to the tank for movement between a first position and a second position. The float member is movable from the first position to the second position in response to an increase in fluid level within the storage chamber. The vent passage remains open for venting the storage chamber when the float member is in the first position and is blocks the vent passage in the second position.

Claims (20)

1. A portable waste transfer tank comprising:

a holding tank defining an internal cavity;

a flexible hose directly coupled to the holding tank and in fluid communication with the internal cavity; and

a hose support member directly coupled to the holding tank for rotation between a stored position and an extended position, the hose support member at least partially surrounding the flexible hose in a circumferential direction and operative to guide and support the flexible hose;

wherein the holding tank defines a recess at an end thereof, the recess extending from a top surface of the holding tank to a bottom surface of the holding tank, an upper portion of the hose support member circumferentially surrounding the flexible hose and positioned in the recess when the hose support member is in the stored position and rotated from the recess in the extended position.

2. The portable waste transfer tank of claim 1 , wherein the hose support member guides at least a portion of the flexible hose for movement between the stored position and the extended position within a plane.

3. The portable waste transfer tank of claim 1 , wherein the hose support member extends vertically in the stored position and horizontally in the extended position.

4. The portable waste transfer tank of claim 1 , wherein the hose support member includes a first end defining a hooked portion.

5. The portable waste transfer tank of claim 4 , wherein the hooked portion rotatably couples to the holding tank.

6. The portable waste transfer tank of claim 4 , wherein the hose support member includes an opposite second end tubular in shape and a flange extending radially therefrom, the flange defining a support surface.

7. The portable waste transfer tank of claim 1 , wherein the hose support member is constructed of metal.

8. A portable waste transfer tank comprising:

a holding tank defining an internal cavity, the holding tank defining a recess at an end thereof, the recess extending from a top surface of the holding tank to a bottom surface of the holding tank;

a flexible hose directly coupled to the holding tank proximate both the recess of the holding tank and the bottom surface of the holding tank, the flexible hose in fluid communication with the internal cavity; and

a hose support member including a first end directly coupled to the holding tank, the hose support member rotatable relative to the holding tank between a stored position and an extended position, the hose support member at least partially surrounding the flexible hose in a circumferential direction and operative to guide and support the flexible hose;

wherein a second end of the hose support member circumferentially surrounds the flexible hose and is positioned in the recess when the hose support member is in the stored position and rotated from the recess in the extended position.

9. The portable waste transfer tank of claim 8 , wherein the hose support member guides at least a portion of the flexible hose for movement between the stored position and the extended position within a plane.

10. The portable waste transfer tank of claim 8 , wherein the hose support member extends vertically in the stored position and horizontally in the extended position.

11. The portable waste transfer tank of claim 8 , wherein the first end of the hose support member defines a hooked portion.

12. The portable waste transfer tank of claim 11 , wherein the hooked portion rotatably couples to the holding tank.
