May 14, 1963 N. L. PADZIESKI DEVICE FOR DISPENSING PREDETERMINED QUANTITIES OF LIQUID Filed Dec. 5, 1960 a R m $4 m m 3 7 m m V I M I I I l l l l l I l w A i States This invention relates to containers of the flexible Wall type and aims to provide a predetermined portion dispenser, which may be applied in lieu of the container closure for accurately dispensing a predetermined quantity of the material within the container.

An important object of the invention is to provide a dispenser for dispensing a measured quantity of material, wherein a surplus quantity fed into the measuring compartment will be returned into the container, thereby insuring an accurate measurement at all times.

Other and further objects and advantages of this invention will be hereinafter described and the novel features thereof defined in the appended claim.

In the drawing:

FIGURE 1 is an elevational view of the measuring cap, forming the subject matter of the present invention.

FIGURE 2 is a vertical sectional View through a container, and measuring cap, the sectional view of the measuring cap being taken on line 2-2 of FIGURE 1.

FIGURE 3 is a sectional View taken on line 3-3 of FIGURE 2.

Referring to the drawing in detail, the container of the flexible wall type, is indicated generally by the reference character 5 and is provided with the usual neck 6 tormed with external threads 7 on which the usual threaded cap is secured.

The device forming the subject matter of the present invention comprises a tubular body portion 8 which is provided with a partition 9, dividing the tubular body portion into an upper measuring chamber '10 and a closure chamber 11, the closure chamber having threads formed in the wall thereof to cooperate with the external threads 7 in securing the tubular body portion on the neck of a container, in lieu of the conventional threaded closure.

The partition 9 is formed with an opening, through which the tube 12 extends, the tube being of a length to extend to a point adjacent to the bottom of the container as indicated by FIGURE 2 of the drawing, where it is beveled as at 13 to allow the contents of the container to pass freely into the tube 12.

The other end of the tube 12 extends laterally at '14 where it is also beveled providing a discharge nozzle which discharges material from the container, at a point adjacent to the wall of the upper measuring chamber 10.

The outer or discharge end of the upper measuring chamber is normally closed by means of the hinged closure 15 which has a hinged connection at 16. The closure 15 is formed with a snap tastener 17 that holds the closure in a closed position, against accidental movement.

Extending from the closure, is a finger piece 18 for effecting opening or the closure 15, when it is desired to dispense the contents of the measuring chamber.

atent ice It might be here stated that the nozzle of the laterally extended end of the tube 12 is disposed towards the hinge of the closure 15, thereby preventing excess liquid from passing through the nozzle '15 during the discharge of the material from the measuring chamber, since the laterally extended end of the tube 12 will be disposed upwardly during the pouring operation. It will also be noted that because of the construction and location of the laterally extended end 14, the contents of the bottle or container will be directed towards the side or wall of the measuring chamber, rather than directing the material outwardly against the cap. It will of course be understood that it is within the scope of the invention to provide these caps of various sizes for dispensing various predetermined quantities of liquid, thereby eliminating waste of material which is packaged in containers or bottles which necessitate the tipping of the containers or bottles, to dispense the liquid.

It is further pointed out that the liquid may be dispensed in predetermined measured quantities while the container is held in one hand and pressure is directed to the flexible wall container with the hand holding the container.

It is believed that in view of the tforegoing description and disclosure in the drawing, the construction and operation of the present invention will be obvious, and that a further description is unnecessary.

What is claimed is:

A device for dispensing a predetermined quantity of a liquid adapted to seat in the mouth of a vertical flexible walled container, comprising an open ended cylindrical body, a partition extending transversely within said body and dividing said body into an upper measuring chamber and a lower closure section, said closure section having internal threads adapted to engage external threads surrounding the neck of the container, said partition contacting and closing the said mouth of said container, an elongated tube extending through the said partition and disposed axially of the said partition and said container, the lower end of said tube terminating adjacent to the bottom of said container, the upper end of said tube having a bevelled end with the bevel directed toward said partition and being laterally disposed at right angles and terminating adjacent the upper end of said measuring chamber, and spaced from the side wall thereof and a hinged closure normally closing the measuring chamber, the upper end of said tube being directed toward the hinged edge of said closure.
