Abstract

A liquid dispensing closure cap for application to a flexible wall container. The cap has a delivery tube extending downwardly into the container and upwardly in a pedestal above the cap top. A dosage cap is seated on the top of the cap. A closure lid is hinged to the pedestal for closing over the pedestal and dosage cap. A spout connects the upper end of the delivery tube to deliver liquid to the dosage cup as the container is squeezed. Closure of the lid prevents liquid delivery through the spout. The cup is removable from the cap and container for use, as where mouth wash is dispensed therein.

Claims

1. A liquid dispensing closure having a removable dosage cup and means for attachment to a flexible wall container comprising, in combination:

a base cap having a top and a depending cylindrical skirt for attachment to said container;

a pedestal extending upwardly from said cap top;

a dosage cup removably seated on said cap top and having a side wall, said side wall being configured to receive said pedestal to provide a contiguous contact therewith;

a closure lid hingingly connected to said pedestal for closure of said dosage cup; and

a delivery tube extending downwardly from said cap top adapted to extend to the bottom of said container and extending upwardly from said cap top through and enclosed by said pedestal for delivery of liquid from said container to said dosage cup when said lid is in an open position and sealed from delivery when said lid is closed.

2. The liquid dispensing closure of claim 1 further including a valve post extending upwardly in said dosage cup and a spout-valve member attached to the upper end of said delivery tube, spanning said pedestal, and having an outlet orifice juxtaposition over the end of said valve post for cooperation therewith to an open position when said lid is open for delivery of liquid through said orifice and to a sealed position when said lid is closed.

3. The liquid dispensing closure of claim 2 wherein the orifice on said spout-valve member and the top of said valve post have complementary conical sealing surfaces.

4. The liquid dispensing closure of claim 3 further comprising a locking tab depending from the inside surface of said closure lid positioned to press against said spout-valve member when said lid is in a closed position pushing said conical sealing surfaces into closed sealing contact.

5. The liquid dispensing closure of claim 1 wherein said pedestal includes a hollow housing having an inside wall portion within the projected area of the base cap and an outside wall portion extending upwardly from the cylindrical skirt of said base cap and said dosage cup has a vertical wall portion contiguous with the inside wall portion of said housing and another vertical wall portion extending upwardly from the cylindrical skirt of said base cap, contiguous and forming with the outside wall portion of said housing a cylindrical extension of said skirt.

6. The liquid dispensing closure of claim 5 further including a valve post extending upwardly in said dosage cup and a spout-valve member attached to the upper end of said delivery tube spanning the inside wall portion of said housing and the vertical wall portion of said dosage cup with an outlet orifice in said spout-valve member juxtapositioned over the end of said valve post for cooperation therewith providing an open position when said lid is open for delivery of liquid through said orifice and providing a sealed position when said lid is closed.

7. The liquid dispensing closure of claim 1 wherein said base cap has a rim extending upwardly from said top and said dosage cup has a recess at its lower end for cooperative confinement with said rim to form a flush surface between said base cap skirt and said dosage cup.

8. A liquid dispensing closure having a removable dosage cup and means for attachment to a flexible wall container comprising, in combination:

a base cap having a top and depending cylindrical skirt with means for attachment to said container;

a pedestal housing extending upwardly from said cap top and having an inside wall portion within the area of said cap top and an outside wall portion extending upwardly and flush with said cylindrical skirt;

a dosage cup removably seated on said cap top having a wall portion contiguous with the inside wall portion of said pedestal housing and an outside wall portion flush with and extending upwardly from said cap skirt to form with said outside wall portion of said housing a cylindrical extension of said skirt;

a closure lid hingingly connected to the outside wall portion of said pedestal housing for closure of the top of said dosage cup and said housing;

a delivery tube extending downwardly from said cap top adapted to extend to the bottom of said container and extending upwardly from said cap top through said pedestal housing;

a valve post extending upwardly in said dosage cup;

a spout-valve member attached to the upper end of said delivery tube and spanning said pedestal housing and dosage cup wall to provide a downwardly directed orifice juxtapositioned over the end of said valve post;

and a locking tab depending from the inside surface of said closure lid positioned to press against said spout-valve member when said lid is in a closed position closing said orifice against the top of said valve post to prevent delivery of liquid therethrough, and upon opening of said lid, the lifting of said locking tab providing a free flow path for dispensing liquid from said container through said delivery tube and spout valve member out of said orifice and over said valve post to fill said dosage cup.
