Abstract

A bottle/cap assembly with sweep-and-drain action includes a bottle, a cap and a sweep-and-drain mechanism. The bottle has in series, from the bottom to the top, a closed bottom, a body sidewall, a cylindrical neck sidewall, and an open top. The cap is configured and dimensioned to be rotatably received about the neck sidewall and includes a closed cap top to close the open top and prevent egress of liquid from within the bottle. The sweep-and-drain mechanism includes (i) a circumferentially spaced plurality of vertically extending grooves or slots in the bottle extending downwardly from the open top through said neck sidewall, and (ii) a circumferentially spaced plurality of radially extending vanes or wipers projecting downwardly from the closed cap top towards the open top. When the cap is disposed on the bottle with the vanes or wipers proximate to the open top, rotation of the cap relative to the bottle causes the vanes or wipers to circumferentially sweep and push any liquid accumulated on the open top into a position vertically aligned with the grooves or slots so that such accumulated liquid can drain downwardly through the grooves or slots towards the closed bottom under the influence of gravity.

Claims

1. A bottle/cap assembly with sweep-and-drain action, said assembly comprising:

(A) a bottle having in series, from the bottom to the top, a closed bottom, a body sidewall, a cylindrical neck sidewall, and an open top;

(B) a cap configured and dimensioned to be rotatably received about said neck sidewall and including a closed cap top to close said open top and prevent egress of liquid from within said bottle; and

(C) a sweep-and-drain mechanism including;

(i) a circumferentially spaced plurality of vertically extending grooves or slots in said bottle extending downwardly from said open top through said neck sidewall, and

(ii) a circumferentially spaced plurality of radially extending vanes or wipers projecting downwardly from said closed cap top towards said open top;

whereby, when said cap is disposed on said bottle with said vanes or wipers proximate to said open top, rotation of said cap relative to said bottle causes said vanes or wipers to circumferentially sweep and push any liquid accumulated on said open top into a position vertically aligned with said grooves or slots so that such accumulated liquid can drain downwardly through said grooves or slots towards said closed bottom under the influence of gravity.

2. A bottle/cap assembly with sweep-and-drain action, said assembly comprising:

(A) a bottle having in series, from the bottom to the top, a bottom portion, a body portion, a neck portion and a top portion;

said bottom portion defining a closed bottom, said top portion defining an open top, said neck portion defining a cylindrical neck sidewall, and said body portion defines a body sidewall;

(B) a cap configured and dimensioned to be rotatably received about said neck sidewall and including a closed cap top to close said open top and prevent egress of liquid from within said bottle; and

(C) a sweep-and-drain mechanism including;

(i) a circumferentially spaced plurality of vertically extending grooves or slots in said bottle extending downwardly from said top portion through said neck portion, and

(ii) a circumferentially spaced plurality of radially extending vanes or wipers projecting downwardly from said closed cap top;

whereby, when said cap is disposed on said bottle with said vanes or wipers proximate to said top portion, rotation of said cap relative to said bottle causes said vanes or wipers to circumferentially sweep and push any liquid accumulated on said open top into a position vertically aligned with said grooves or slots so that such accumulated liquid can drain downwardly through said grooves or slots into said body portion under the influence of gravity.

3. The assembly of claim 2 wherein said bottle is a two-piece plastic construction including a clear lower portion to reveal the color of the liquid and an opaque upper portion to conceal the drain mechanism, said lower and upper portions being sealed together in airtight relationship.

4. The assembly of claim 3 wherein said lower and upper portions are ultrasonically sealed together.

5. The assembly of claim 2 wherein said body portion defines a body sidewall having a width dimension greater than the corresponding dimension of said neck sidewall.

6. The assembly of claim 2 wherein said open top slopes downwardly and inwardly.

7. The assembly of claim 6 wherein said vanes or wipers slope downwardly and inwardly.

8. The assembly of claim 2 wherein said vanes or wipers slope downwardly and inwardly.

9. The assembly of claim 2 wherein said open top defines an upper surface and said vanes or wipers define a lower surface, said lower surface of said vanes or wipers being closely proximate to said upper surface of said open top, thereby to effect a sweeping action on said upper surface during relative rotation of said cap and said bottle.

10. A bottle/cap assembly with sweep-and-drain action, said assembly comprising:

(A) a bottle having in series, from the bottom to the top, a bottom portion, a body portion, a neck portion and a top portion;

said bottom portion defining a closed bottom, said top portion defining an open top, said neck portion defining a cylindrical neck sidewall, and said body portion defines a body sidewall;

(B) a cap configured and dimensioned to be rotatably received about said neck sidewall and including a closed cap top to close said open top and prevent egress of liquid from within said bottle; and

(C) a sweep-and-drain mechanism including;

(i) a circumferentially spaced plurality of vertically extending grooves or slots in said bottle extending downwardly from said top portion through said neck portion, and

(ii) a circumferentially spaced plurality of radially extending vanes or wipers projecting downwardly from said closed cap top;

said open top defining an upper surface which slopes downwardly and inwardly, said vanes or wipers defining a lower surface which slopes downwardly and inwardly, said lower surface of said vanes or wipers being closely proximate to said upper surface of said open top, thereby to effect a sweeping action on said upper surface during relative rotation of said cap and said bottle;

whereby, when said cap is disposed on said bottle with said vanes or wipers proximate to said top portion, rotation of said cap relative to said bottle causes said vanes or wipers to circumferentially sweep and push any liquid accumulated on said open top into a position vertically aligned with said grooves or slots so that such accumulated liquid can drain downwardly through said grooves or slots into said body portion under the influence of gravity.

11. The assembly of claim 10 wherein said bottle is a two-piece plastic construction including a clear lower portion to reveal the color of the liquid and an opaque upper portion to conceal the drain mechanism, said lower and upper portions being ultrasonically sealed together in airtight relationship.
