Abstract

A container and spout assembly in which the spout is pivotally attached to the container. The spout is pivotally moveable between a closed position in which a spout exterior wall is flush with the container sidewall and an open position in which a spout interior wall is flush with the sidewall and spout legs frictionally engage a detent. The spout accommodates a metered dose of product. In the fully open position, the spout seals the opening in the sidewall to prevent product from exiting the container while a metered dose is dispensed from the open spout.

First claim

What is claimed:

1. An overcap and spout assembly for a container for dispensing a metered amount of product from the container, the overcap and spout assembly comprising:
an overcap including a sidewall connected to a top panel, the sidewall defining an opening that mateably receives a spout, the sidewall including an exterior surface and an interior surface, the opening including a first end and a second end, the sidewall including a detent disposed adjacent to the second end,
the spout including an interior wall connected to an arcuate exterior wall at a corner that is hingedly connected to the first end of the opening, the interior wall and arcuate exterior wall extending away from each other as they extend away from the corner, the interior wall including a distal end opposite the corner, the arcuate exterior wall including a top edge, a bottom edge and a distal edge opposite the corner,
the spout further including a top wall and a bottom wall, the top wall connecting the interior wall to the top edge of the arcuate exterior wall and the bottom wall connecting the interior wall to the bottom edge of the arcuate exterior wall, the top wall including a distal edge disposed opposite the top wall from the corner, the bottom wall including a distal edge disposed opposite the bottom wall from the corner,
the distal edges of the arcuate exterior wall, the top wall and the bottom wall forming a spout opening with the interior wall; wherein
the distal end of the interior wall includes a pair of spaced-apart legs, the detent being disposed between the spaced-apart legs when the spout pivots to an open position.

2. The assembly of claim 1 wherein the sidewall is cylindrical with a central axis and a radius that defines a curvature of the sidewall, the arcuate exterior wall of the spout also having a curvature that is defined by the radius of the sidewall.

3. The assembly of claim 1 wherein the distal end of the interior wall engages the interior surface of the sidewall when the spout is pivoted to an open position.

4. The assembly of claim 1 wherein the corner is hingedly connected to the sidewall with a living hinge.

5. The assembly of claim 1 wherein the corner, top wall, bottom wall, arcuate exterior wall and a portion of the interior wall that is connected to the top and bottom walls define a chamber of a predetermined volume for dispensing a metered amount of powder.

6. The assembly of claim 1 wherein the interior wall is arcuate and has a curvature that is defined by a radius of the sidewall.

7. The assembly of claim 1 wherein the detent forms a protrusion in the interior surface of the sidewall.

8. The assembly of claim 7 wherein the legs straddle the detent when the spout pivots to an open position.

9. The assembly of claim 8 wherein the legs frictionally engage the detent when the spout pivots to an open position.

10. The assembly of claim 1 wherein the legs prevent the interior wall of the spout from being pulled through the opening disposed in the sidewall of the overcap when the spout pivots to an open position.

11. The assembly of claim 1 wherein the legs form a snap-fit around the detent when the spout pivots to an open position.

12. A container comprising:
a sidewall defining an opening, the opening including a first end and a second end, the sidewall comprising an interior surface and a detent disposed adjacent to the second end, the detent forming a protrusion in the interior surface of the sidewall; and
a spout comprising an interior wall connected to an arcuate exterior wall at a corner that is hingedly connected to the first end of the opening, the interior wall including a distal end opposite the corner, the distal end including a pair of spaced-apart legs; wherein
the spout is pivotally moveable between a closed position in which the arcuate exterior wall is flush with the sidewall and an open position in which the interior wall is flush with the sidewall and the legs frictionally engage the detent.

13. The container of claim 12 wherein:
when the spout is in the open position the distal end of the interior wall extends beyond the second end of the opening.

14. The container of claim 12 wherein:
the spout interior wall and arcuate exterior wall extend away from each other as they extend away from the corner.

15. The container of claim 14 wherein:
the arcuate exterior wall includes a top edge, a bottom edge and a distal edge opposite the corner; and
the spout further comprises a top wall and a bottom wall, the top wall connecting the interior wall to the top edge of the arcuate exterior wall and the bottom wall connecting the interior wall to the bottom edge of the arcuate exterior wall, the top wall including a distal edge disposed opposite the top wall from the corner, the bottom wall including a distal edge disposed opposite the bottom wall from the corner; and wherein
the distal edges of the arcuate exterior wall, the top wall and the bottom wall form a spout opening with the interior wall.

16. The container of claim 12 wherein:
when the spout is in the open position the detent is disposed between the spaced-apart legs.

17. The assembly of claim 12 wherein:
when the spout is in the open position the legs form a snap-fit around the detent.

18. The assembly of claim 12 wherein:
the container further comprises a transverse rib disposed between the detent and the second end of the opening; and
the spout further comprises a latch disposed on the distal edge of the arcuate exterior wall; and wherein
when the spout is in the closed position the latch forms a snap fit with the transverse rib.
