DISPENSING-CONTAINER.

Specication of Letters Patent.

Patented Aug. 16, 1910.

Application filed September 29, 1909. Serial No. 520,074.

To all 'whom 'it may concern:

Be it known that I, CLARENCE E. STUBBS, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Dispensing Containers, of which the following is a specification.

This invention relates to a dispensing container or receptacle for viscous, semi-fluid or like substances, such for example, as salves, pastes, powders, iiuids, lubricants and similar materials,wherein the Vmaterial may be discharged in such quantities as are desired for immediate use.

@ne object of the invention is to provide an improved container of this: character which shall be simple, practical and inexpensive and which will protect the unused portion of the contents fromV the action of.

the air and from any exterior foreign matter.

Another object is to provide an improved construction of container having a discharge -outlet and a disk or head movable away from said outlet to effect a discharge of the contents at said outlet.

A further object is to provide an improved container having a rotatable cover with an outlet extending therethrough a disk or head interposed between the rotatable cover of the containerand the material therein and head whereby to move the same away from the said cover of the container to discharge the contents through the cover outlet.

With these and other objects in view' the accompanying drawingsillustrate practical applications of the invention, in which,-

Figure 1, is a vertical longitudinal section through a jar embodying the features of the invention. Fig. 2, is a plan view of the same. Figs. 3 and 4 are sectional views of a modified form of container, and Figs. 5 and 6, are also sectional views of another modiied form of invention.

Referring to the drawings, and particularly'Figs. 1 and 2 thereof, the numeral, 1, designates the container proper which may have any desired interior or exterior shape but the interior walls, 2, of which areparallel so'as to form a chamber of uniform size longitudinally. One end 3, of the container is preferably permanenti closed although this is immaterial, as sai end may be concontainer embodying theJ structed so that it can be opened for the -purpose of refilling the container but during the operation of discharging the contents said end will be closed. The upper end of the lcontainer is provided with a cover, 4, whitzh may be attached thereto in any preferred manner but in the form shown in Figs. 1 and 2 the container is provided with an exterior shoulder, 5, while the cover has a depending flange, 6, with an inturned lower edge, 7, ywhich takes beneath the said shoulder to secure the cover in place. The cover is provided with an opening, 8, so that a tube, 9, with a'passage therein may extend therethrough down into the container with its lower end at or adjacent to the bottom and having an opening, 10, therein to permit the passage of material from the receptacle to the tube passage. This tube is sustained in the container so that it will be held against longitudinal movement with respect to the cover and the bottom or closed end, 3, of the container and the upper projecting end of the said tube'is provided with a discharge opening, 11, at the outer side of said cover through which the contents ofthe conpreferred forms or embodiments of the invention, the tubes, 9, have a central position in the cover and container, and a disk or head, 12 has a perforation, 13, therein through .which the tube extends so that Said disk or head may. be movable on the tube from the upper toward the lower end to force the contents up through the tube and out at the upper end thereof. The meansV employed to operate Vthe disk or .head 'so as to cause it to travel downwardly and away from the discharge opening, 11, may vary, but I prefer to provide the said Ydisk or head with screw threads which will engage a rotatable screw-threaded support so that as the latter is turned the head will be madeto travel downwardly over the said support.

In the forms shown in'Figs. 1 and 3, the tubes, 9, are provided with exterior screwthreads, 14, and the perforation, 13, of each head or disk permits the threaded tubes to pass up through the head to the upper side thereof.

As the disk or head is preferably of thick cork or .similar material, I prefer to reinforce the same 'on the upperA sida-'that is, at that side immediately below the cap or` cover, andJ while this reinforcement may vary in-construction, I prefer to employ a plate, 15,'hav1ng a central u -turned ange,

'16, which isalso screw-three ed so as to engage the threads on the tube, 9, so that as the disk or head is forced down on top of the contents of the container the same will `not bend or break diametrically.

In the construction shown in Figs. land 2, the cover and the upper rejecting end of the tube are rigidly. unite being soldered or otherwise secured together, so that by turning the cover, the .tube will be rotated in the container and the disk or head will be advanced along the screw and thus compress the contents suiiciently to drive it up through the tube passage to the .outlet over the cover.

A cap, 17 is preferably provided on the' cover,4, as shown in Figs.' 1 and 2 to -close the discharge end of the tube toprotect it from dust and dirt.

In the device shown 3 and 4, the

container is provided with a screw-threaded upper end, 18,v and the cap-ange is also threaded so. as to engage the container and is-rigid thereon. To provide for the travel of the disk or head along the tube, the latter` has its upper end passing through and'rig? idly attac ed to 'a cover-disk, 19, which 1s rotatable on the cover while the lower end of .the tube is seated in "a central depression, 20,

in the bottom or closed end,.3, of the'container and is provided with perforations, 21, through which the-contents 'of the container may, ass to find outlet throu h the tube. It w therefore-be seen that' e operation ofthe disk or'headadvancing alo the tube to force the material up throng the lower end of the tube is the same as in the device shown in Figs. 1 and 2. It 'will also be seen that in the device shown in Figs. 3

and 4, it is shown that theinterior or eX- terior shape of the container in cross-section need not be round but may be angular.

In Fig. 5 it is shown that the cover, 4, may be secured in an annular interior I groove, 22, Ain the container and that the atter may be provided with interior screw- ,threads, 23, with which circumferential threads, 24, on the disk or head engage. .In this construction the outer projecting discharge-end of the tube is provided with a v flange orcollar, 25, by which the tube may y `on the tube and through a groove' in the1 disk or head so as to produce a spline and: feather connection between the two'.

i thereby permitting a longitudinal but nonrotating movement of the disk on'the tube. VBy this construction the tube may be fheld j 1 I disk are rigidl be edandarib 26 extends 1o tudinalmsp ngi and the container revolved to cause the disk or head to move on the tube. It is obvious from this latter view in the drawing that the exterior cross-sectional sha of the container is immaterial and may e varied.

In the device shown in Fig 1, the cover and. the hollow stem or tube are rigidly connectedso they will turn together and in the device shown in Fig. 3, the tube and .cover connected. In Fi 5 the tube carries a nge or collar by w ich the tube maybe gras ed and either it or the container revolll7 to cause 4the 4disk to travel on the tube to force the material into the lower. end of the tube.

Having thus described my invent1on what I claim and desire to secure by Letters Patent is,-

1. `In a dispensing container the combination with a receptacle closed at .one end, of a tube extending centrally in: the receptacle and having its outlet end projecting beyond the'receptacle and adjacent to its other end having an inlet to receive material from 'the rece tacle; a diskmovable longitudinally on 51e tube, and a plate having a central openin which receiv the tube and extends latera y A:from and rigidly engages the pra jecting outlet end ofthe tube,+sa1d p ate i'tt' around the tube below` its outlet.

2. na dispensin container the combina- Y tion with a receptac e closed at one end; of a V having tion with a receptacle,- 'ofa rotatable cover at one end of the receptacle; ac'tube extending through and projecting above and below. the cover and havin an opening at-1ts lower end forfthe inlet o material from the receptacle and an opening above the cover for the discharge of material,fsaid cover and tube being rigidly connected, and a disk the rotatable cover.

In testimony' whereof I aiiix my signature in presence of two witnesses. .l
