Abstract

A plunger with evaporative base is disclosed where the evaporative base has a standoff joined to a drainage bottom and a stump and stump channel arrangement for keeping the plunger suspended slightly above the drainage bottom. A plunger is disclosed that mates with the evaporative base and has a plunger bell standoff that mates with the evaporative base standoff to further keep the plunger suspended slightly above the drainage bottom. The outer perimeter of the bell of the plunger is slightly smaller than the inner diameter of the evaporative base body to allow for air circulation between the plunger bell and the evaporative base. Good air circulation and drying promotes cleanliness and reduces the incidence of mold, mildew and bacteria on the plunger and base.

Claims

1. An evaporative base for receiving a plunger, the evaporative base comprising:

a generally cylindrical body having an inner volume;

a drainage bottom joined with the generally cylindrical body;

a standoff comprising a base and joined with the drainage bottom at the base of the standoff;

a bell receiver formed as a space between the inner volume of the generally cylindrical body and the standoff;

a first stump joined with the drainage bottom; and

a first stump channel joined with the first stump.

2. The evaporative base of claim 1, wherein the standoff is shaped as a truncated cone.

3. The evaporative base of claim 1, wherein the standoff further comprises a standoff depression and a drainage crown having at least one drainage cut.

4. The evaporative base of claim 1, wherein the standoff further comprises a standoff depression and a drainage crown having four drainage cuts.

5. The evaporative base of claim 1, further comprising a second stump, a third stump and a fourth stump.

6. The evaporative base of claim 5, further comprising a second stump channel, a third stump channel and a fourth stump channel.

7. A plunger for use with an evaporative base, the plunger comprising:

a handle having a male threaded end;

a plunger bell comprising a flare, a plunger bell standoff located inside the plunger bell, a bell funnel, and a threaded fitting;

the threaded fitting of the plunger bell being coupled to the male threaded end of the handle.

8. The plunger of claim 7, further comprising a plunger bell flare circumferential edge extending from the outer perimeter of the plunger bell.

9. The plunger of claim 7, further comprising a plunger bell standoff circumferential edge extending from the outer perimeter of the plunger bell standoff.

10. The plunger of claim 7, further comprising a plurality of ribs joined to the inner surface of the plunger bell.

11. The plunger of claim 7, further comprising a flat circumferential edge around the perimeter of the threaded plunger bell fitting.

12. The plunger of claim 11, further comprising a flared handle skirt joined with the handle at the start of the male threaded end.

13. The plunger of claim 7, wherein the handle is hollow and further comprises a handle insert to plug a hollow end of the handle.

14. The plunger of claim 7, further comprising a handle end joined to the handle.

15. The plunger of claim 7, further comprising a bevel circumferentially connected to the flare of the plunger bell.

16. A plunger and evaporative base comprising:

a plunger comprising a handle having a male threaded end;

a plunger bell comprising a flare, a plunger bell standoff located inside the plunger bell, a bell funnel, and a threaded fitting;

the threaded fitting of the plunger bell being coupled to the male threaded end of the handle;

an evaporative base for receiving the plunger, the evaporative base comprising;

a generally cylindrical body having an inner volume;

a drainage bottom joined with the generally cylindrical body;

a standoff comprising a base and joined with the drainage bottom at the base of the standoff;

a bell receiver formed as a space between the inner volume of the generally cylindrical body and the standoff;

at least one stump joined with the drainage bottom; and

at least one stump channel joined with the first stump.

17. The plunger and evaporative base of claim 16, wherein the plunger bell standoff contacts the evaporative base standoff to keep the plunger from contacting the drainage bottom of the evaporative base.

18. The plunger and evaporative base of claim 16, wherein the outer perimeter of the plunger bell is slightly smaller than the inner perimeter of the evaporative base body to allow for air circulation between the plunger bell and the evaporative base.

19. The plunger and evaporative base of claim 16, wherein the standoff of the evaporative base further comprises a standoff depression and a drainage crown having four drainage cuts.

20. The plunger and evaporative base of claim 16, further comprising a second stump and a second stump channel, a third stump and a third stump channel, and a fourth stump and a fourth stump channel.
