(o1. 2in-71s) 4 Claims.

This invention relates to a dispenser primarily for materials in the form of cream or paste.

It is aimed to provide a device capable of repeated use with containers lof materials in cream or paste condition and which containers may be made of glass or any substitute for metal in order to conserve the latter. A

A particular object is to provide a novel dispensing means under valve control and in which the material to be dispensed is maintained under pressure so that it will be ejected automatically upon opening of the valve means.

Further, an important object, is to provide novel means wherein the tension on the urging spring for the ejecting piston or follower may .be varied so as to be greatest when the container is full and weaker when the container is nearly empty.

The more specific objects and advantages will become apparent from a. consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings- Figure l is a View partly in elevation and partly in central vertical section, through dispensing apparatus according to my invention;

Figure 2 is a fragmentary view of the parts of Figure l, with the tube nearly full and the spring at maximum tension;

Figure 3 is a View of the parts of Figure 1 taken at a right angle thereto, with various parts broken away and in sections to disclose details;

Figure 4 is an enlarged horizontal section taken on the line lil-ll of Figure 3;

Figure 5 is a vertical section taken on the line 5 5 of Figure 3; and

Figure 6 is a cross section taken on the line 6--6 of Figure 3.

Referring specifically to the drawings wherein like reference characters designate like or similar parts, I propose to use a receptacle or container I0 which is preferably made of glass, although it may be made of plastic or any other suitable material and during the emergency preferably of a material other than metal in order to conserve the latter. Such container It is adapted to be sold in lieu of the present day collapsible tubes and with a screw cap thereon.

In lieu of the screw cap, I use a screw cap Il, in threaded engagement at I2 with the upper end portion of the container IEI. Cap II has a central opening in which the controlling head I3, in the form of a tube, is mounted for vertical adjustment, such head or tube having diametrically disposed outwardly extending ribs at I4. The hole in the cap II conforms in shape to the tube I3 with the ribs I and hence, the head or tube cannot turn relatively to the cap I I.

A suitable piston or follower I5 is slidable within the container II! to expel the paste, cream or the equivalent I6, upwardly through the bore of an outlet tube Il, to the lower ends of which piston l is` rigidly conected. The upper end of the tube I'I is preferably crooked as shown at I8 and adjacent the free terminal or outlet end thereof has a sleeve I9 rigidly fastened thereto. A pair of levers 20 are pivoted at 2| to the sleeve I9 in order to actuate oppositely movable slide valves 22 towhich the levers are connected by pin and slot connections at 23. Valves 22 in closed position abut as shown in Figure 5 and they slide in slots 24 provided through the tube and sleeve I. Expansive springs 25, mounted in recesses as shown in sleeve i9 and levers 2U, urge the levers at their upper ends apart so as to maintain the valves 22 in contact and closed. The valves 22 may be opened by engagement of the fingers with handle portions 26 on the levers.

The head or tube I3 at its lower end is provided with a flange 2l, abutted by an expansive coil spring 28, surrounding the tube I8 and also abutting the piston or follower I5. The tube is adapted to be held in two or more adjusted positions or at different elevations, by the engagement of a fork or yoke 29, in series of slots 33 provided at dilferent elevations along the tube or head I3. Yoke 29 has a handle 3l slidably extending through a slot 32 in the depending wall and handie 3l has an elongated slot 33 through which a pin 32 passes and which is suitably fastened to the cap Il. Thetube I3 cannot be accidentally lifted out of the cap II since it has lugs 35 extending outwardly therefrom and which at the uppermost limit of movement of the tube I3 abuts the under surface of the cap II as shown in Figure 2, and since handles 35 on such tube on the exterior of the container lil, limit downward movement of the tube as well as providing means to enable ready adjustment of the tube.

Engagement of the yoke 29 in the lower series of slots 3D, as shown in Figure 2, will provide maximum tension for the spring 28 and thus maximum pressure on the piston I5, for ejection with the uppermost slots 30 as shown in Figure 1, the pressure on the material I6 under such conditions not being excessive.

The tube I8 has diametric outwardly extending ribs or flanges at 3'I which occupy the spaces or grooves of the ribs I4, and, accordingly, the tube I8 cannot turn relatively to the container I0.

Various changes may be resorted to provided they falll within the spirit and scope of the invention.

I claim as my invention:

l. In combination with a container, having an ejecting tube and a piston to force material through the tube, a head slidable relatively to the tube and to the container, means to prevent relative rotation of the tube and head, an expansive spring abutting the piston and the head, and means on the container to secure the head at different elevations to control the tension of said spring.

2. In combination With a container, having an ejecting tube and a piston to force material through the tube, a head slidable relatively to the tube and to the container, an expansive spring abutting the piston and the head, and means on the container to secure the head at diiierent elevations to control the tension of said spring, the container having a slot through which said head passes, said head having a rib intertted with the container at said opening to prevent turning of the head.

3. In combination with a container, having an ejecting tube and a piston to force material through the tube, a head slidable relatively to the tube and to the container, an expansive spring abutting the piston and the head, and means on the container to secure the head at different elevations to control the tension of said spring, the container having a slot through which said head passes, said head having a rib interiitted with the container at said opening to prevent turning of the head, said head being in the form of a tube surrounding the dispensing tube, and the dispensing tube having a rib interfitted with the rib on the head.

4. In combination with a container, having an ejecting tube and a Apiston to force material through the tube, a head slidable relatively to the tube and to the container, and an expansive spring abutting the piston and the head, and means on the container to secure the head at different elevations to control the tension of said spring, said head being in the form of a tube surrounding the dispensing tube, and said means consisting of a movable element on the container, and slots in the tube head selectively engageable by said element.
