R. L. CORNELIUS DISPENS ING DEVICE Filed Dec. 31, 1928 4 Sheets-Sheet 4 Patented Apr. 8,. 1930 RICHARD L. CORNELIUS, OF PASO ROBLES, CALIFORNIA DISPENSING DEVICE Application filed December 31, 1928. Serial No. 329,459.

This invention relates to an improved dispensing device which is articularly adapted for use in association w1th collapsible tubes, such as are employed as containers for 5 tooth paste, shaving cream, cold cream and the like.

Briefly, the invention has reference to a structure embodying a container for the marketed tubes, means in the container for 1 systematically and forcibly ejecting the con tents from the tube, and a novel discharge nozzle into and'through which the cream is fed in a ribbon like strip for use.

The object is to provide a structure em- 1 bodying a compact and convenient arrangement of parts so associated and coo crating as to produce a device which will unction in a positive and dependable manner andwhich will fulfill the requirements of an invention of this class in a satisfactory manner.

Figure 12 is a top plan view of Figure 10 with the cover removed.

Attention is first to be confined in the de-v tailed description to Figures 1 to 6 inclusive.

Inthese figures the reference character 13 designates an open ended tube formed adjacent its opposite end with oppositely pressed circumferentially extending beads 14 and 15, respectively. Those portions of the tube-end beyond the beads constitute annuli 16, having outwardly pressed portions 17 at substantially diametrically opposite points forming keepers. On the lower end is a removable cap 18 and on the upper end is a reversible closure 19. The closure 19 and the cap 18 are interchangeable.

This closure comprises a disc-like cover 20, whose rim portion is pressed inwardly as at 21 to form a panel for reception of a rotary ring gear 22. The teeth of this gear occupy a position shown in Figure 3. The remainder of the rim which fits telescopically over the complemental annulus 16 is provided with diametrically opposite matches 23 0'1 a resilient nature which releasably snap over the keepers 17. This cover is formed with a central opening and an inwardly extending screw threaded collar 24. Threaded through the opening and collar is a nozzle 25 having a socket at itsinner end containing a packing ring 26, into which the neck 27 of the conventional collapsible tube 28 is threaded. It is to be noted that the nozzle is provided with-a swivelcd valve 29, having an outstanding finger grip 30.

Mounted for rotation in suitable bearlng brackets 31 within the tube 13 are feed screws 32. There are a pair of these screws and they are located diametrically opposite each other and they are provided at opposite ends with pinions 33 the upper pair of which extend through openings in the grooved portion 21 of the closure 19 as shown in Figure 3 to permit them to mesh with the teeth on the inner periphery of the ring gear 22. Thread ed on the feed screw for longitudinalmovement are bearing blocks 34: carrying a pair of pressing rollers 35.

These rollers are obviously arranged to engage and compress the endportion 33 of the o5 collapsible container 28. As shown 1n Flgure 1, the nozzle is provided with a discharge slot 37 cooperating with the complemental slot 38 in the valve cap 29.

In operation, the collapsible contamer 28 i is placed within the tube 13 with the end a reversible nature.

portion 36between the compressing rollers 35. The neck 27 'is threaded into the discharge nozzle 25 as shown in Figures 1 and .2, Then, the valve cap 29 is rotated to bring theslots 37 and 38 into registery' with each other. Now, by grasping and turning the ring gear 22, it is obviousthat the comple mental pinions 33 will be'rotated andthe feed screws 32 will in turn be rotated. Ro-

- tating the ring 22 in the proper direction will gradually feed the blocks 34 upwardly on the feed screws. The result is that the contents of the container 28 will be'squeezed out into the nozzle and forced through the slots 37 and 38 in an obvious manner.

It'is to be noted that the closure 19 is of For instance, when the entire contents of'the container 28 has been discharged, instead of attempting to feed the blocksv 34 down again to the original position, the cap 18 is removed from the lower end of the tube 13 and replaced by the closure 19. Then, the structure is reversed to'feed the material from the opposite endv thereof.

Substantially the same principle of operation and asimilar structure is employed in the embodiment of the invention appearing in Figures 7 to 12, inclusive. Reference being had to these figures, it will be observed that 39 designates an open ended cylinder or. tube which, in this instance is substantially ovate in cross section. The closure 40 comprises a cover 41, having a central screw threaded hole and having its rim portion'42 fitted telescopically over the complemental end portion 43', of the tubular casing. Here again, retaining means is provided as at 44.- Moreover," the rim portion isprovided withsegmental slots for exposin the operating ring gear 45. The ring gear is rotatably mounted on the nozzle 46 and rests upon the stop or hearing flange .47.. In this form of the inven tion, I also provide a valve cap 48 swivelly mounted on the exposed portion of the nozzle andprovided with a. discharge slot 49, regist'er ng with the complemental slot 50, in the nozzle. The valve cap is equipped with a finger-grip '51. The collapsible container 52 is arranged within the casing and cooperateswith pressing. rollers 53 mounted thelongitudinally movable bearing blocks 54.

Here again, the blocks are'threaded on the feed screws 55 mounted for rotation in bear- -1ng brackets 56. More-over, the feed screws are provided at opposite ends with pinions 57 for cooperation with the teeth onthe outer periphery of the ring gear 45. It will be I noticed from Figure'll that the feed screws tare arranged within the casing asshown for greater com actness andconvenience. It is further evi ent thata removable ca 58 is supplied and is adapted to be replace by the reversible closure 40. In other words, the

closure may be-arranged on either end of vious that I have evolved and produced a g novel mechanical device for dispensing cream, tooth paste and the like, from marketed con tainers, in a convenient and sanitary manner.

The invention is simple and inexpensive, and its use will effect economy by squeezing.

.the entire contents from the marketed container.

, It is thought that by considering the de scription. in connection with the drawings, a clear understanding of the construction, operation and features of the invention will be had. Therefore, a more lengthy description 'is regarded as unnecessary.

Minor changes in shape, size, and rearrangement ofparts coming within the field I of invention claimed may be resorted to, in actual practice if desired.
