DETAILED DESCRIPTION OF THE INVENTION

Referring now to the drawings, an exemplary embodiment of the dispensing closure is generally indicated at 10 in FIGS. 1-10. The squirt dispensing closure 10 is particularly suited for dispensing liquid drink flavor concentrate, but may be used for any squirtable liquid.

The dispensing closure 10 generally includes a closure body 12, a cap 14, a hinge structure 16 connecting the cap 14 to the closure body 12, and a flow baffle 18 which improves a clean, high-velocity squirt dispensing of the product from a flexible, squirt-type container (not shown).

The closure 10 and container may both be formed from plastic materials.

However, the container may alternatively be formed from a foil pouch material, or any other suitable flexible material which can be squeezed to provide pressure within the interior of the container.

The closure body 12 includes a closure deck 20 and a tubular dispensing spout 22 having an upper portion 24 extending upwardly from the closure deck 20 and a lower portion 26 extending downwardly from the closure deck 20. The tubular dispensing spout 22 provides a continuous flow conduit 28 from the interior of the closure body 12 to an exterior thereof. The dispensing spout 22 may alternatively exclude the upper portion 24 thereof and provide a direct dispense from the flow conduit 28 exiting directly at the surface of the closure deck 20.

An inner skirt wall 30 extends downwardly from the closure deck 20 encircling the lower portion 26 of the dispensing spout 22 and provides container mounting formations 32, which may be threads or thread lugs for engagement with corresponding threads on the outer surface of the neck of the squirt container. In the exemplary embodiment as illustrated, the inner skirt wall 30 is segmented and includes thread lugs 32.

An outer decorative skirt wall 34 extends downwardly from the closure deck 20.

The outer skirt wall 34 may be shaped and adapted to match the outer shape of the squirt container to form a continuous outer surface with the container. Alternatively, the closure body 12 may be formed without the outer skirt wall 34 when it is not needed.

The cap 14 may be connected to the closure body 12 by a living hinge structure 16 which is integrally formed with the cap 14 and the closure body 12. Accordingly, it can be appreciated that the cap 14 is movable between open and closed positions (See FIGS. 1 and 3). The cap wall 36 may be shaped and adapted to match the outer shape of the squirt container and outer skirt wall 34 to form a continuous outer surface. In the exemplary embodiment as illustrated, the cap wall 36 is rounded to match the outer skirt wall 34 of the closure body 12.

To provide a seal with the upper portion 24 of the dispensing spout 22, the cap 14 includes a tubular sealing bead 38 extending down from the inner surface of the cap wall 36, which is snap received over the upper portion 24 of the dispensing spout 22 to seal the dispensing spout 22 and container closed.

A tab 39 is formed on the front edge of the cap wall 36, opposite the hinge 16, to facilitate movement of the cap 14 from the closed position (FIG. 1) to the open position (FIG. 3).

The flow baffle 18 operates to restrict flow from the container through the flow conduit 28. As can be seen in FIGS. 2 and 6-10, the flow baffle 18 is mounted to the bottom of the closure deck 20 and includes a bottom wall 40, and a side wall 42 having an peripheral upper edge 44 which is snap received with an annular shoulder 46 surrounding the lower portion 26 of the dispensing spout 22. Referring to FIG. 10, it can be more clearly seen that the upper peripheral edge 44 of the baffle side wall 42 and the shoulder 46 include interfitting snap beads which retain the structures together. This assembly forms an interior baffling space 48 within the closure body 12.

Concentrating now on FIGS. 6-10, a fluid well 50 is formed in the center of the bottom wall 40 and a fluid opening 52 is formed on a peripheral edge of the bottom wall 40 to permit fluid to enter the baffling space 48 from the container. The bottom wall 40 of the flow baffle 18 is sloped downwardly towards the fluid opening 52 to permit fluid within the baffling space 48 to drain back into the container when the container is uprighted.

An arcuate baffling wall 54 extends upwardly from the bottom wall 40 in closely spaced facing relation with the side wall 42 and adjacent the fluid opening 52 and forms an arcuate, restricted flow gap 56 extending from the fluid opening 52 into the baffling space 48 in the interior of the flow baffle 18. The flow gap 56 is best seen in FIGS. 6 and 10. Fluid entering through the opening 52 must past between the baffling wall 54 and the side wall 42 to reach the fluid well 50 inside the baffling space 48.

Additionally, a baffling post 58 extends upwardly from within the fluid well 50 into the flow conduit 28 in the lower portion 26 of the dispensing spout 22 to form a further restricted annular flow passage 60 therebetween. As best seen in FIG. 10, the flow conduit 28 in the lower portion 26 of the dispensing spout 22 and the baffling post 58 have stepped interfitting shoulders 62,64 which create a stepped annular flow passage 60. Also as best seen in FIG. 10, it is pointed out that the outer diameter of the baffling post 58 is smaller than the inner diameter of the flow conduit 28 on both portions of the stepped shoulders 62,64 to provide the restricted annular flow passage 60.

It can therefore be appreciated that the highly restricted flow paths from the interior of the container through the upper portion of the dispensing spout 22 provides a high velocity squirt dispense of the liquid when the container is inverted and squeezed while also providing a clean, no-drip stop of flow when pressure is removed from the container.

While there is shown and described herein certain specific structures embodying various embodiments of the dispensing closure, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the spirit and scope of the underlying inventive concept and that the same is not limited to the particular forms herein shown and described except insofar as indicated by the scope of the appended claims.
