Application; led 'June 9, 1922. .'"Serial No.' 567,069.

Be it known that L VIsAAc `C.'SHALKOP, a citizenof the `United"-Stateafandfa'resident of Philadelphia, in the "county sof Philadelphia and State of Pennsylvania,

I have invented an Improvement fin "Dispensing Devices, of `which the 'following is a 'specilication My invention 'y relates to improvements `ain dispensing devices'of the charaoterin'fwhich the liquid or f semi-liquid material to be.` dispensed is contained withinfa conta-inereisituated within ashell or-handle-an-din which the expulsion of the'said'material iseected by simultaneous rotation ofV the :shell and f container in the 'samer direction. p

I have shown the yinvention asembodied in a 'shaving brushinwhich the container is ofthe 'collapsible' type, but it `is Ato be understood that it maybe' employedfin connection with constructions inwhich thedispensing means is not embodied in a shaving brush and also Vin'which` the container is not of the collapsible type;

Thel principal object of vthe `invention is to provide a new and novelmeans' for causing the container torotatey with the shell within which itis inclosed when saidshell is rotated. f'

'A further objectisto provide a detach- 1 able cap portion of the shell `with means which is adaptedtdengage the'oontainer soA that A"when-the shellfis rotated theicontainer willA be vcaused 'to' Vrotate therewith.

Other objects andadvantages-of the'inf vention will be pointed out intheV detailed description" thereof /whichr follows orf-will be apparent'A from` E'such' description.

In order that the invention may :bef readily understood and'its 'practicalY advantages ffully appreciated, reference-mayf-ber-hadato the'. accompanying drawing in whichvone formot1 mechanical embodiment thereof is depicted, but it will be understoodv #that changes in the detailsl ofconstruotion; may

- be'made within the scope ofthe? claims without departingrom the saidfinvention.

In the drawings:

Fig. 1 'is a viewpartlyiin side and partly in longitudinal central section of a shaving brush provided with the invention;

Fig. 2 is a view in longitudinal section of the outer or lower portion of the container for the material to be dispensed which is `adapted to be situated within the hollow "handle or lshell of the device,

the:-:said View also indicating indentations caused bythe means for connecting'avpart of'the'fshell'and the said container together to' cause them to rotate-in'unison when the shell fisrotated;

Fig." 3 is abottom plan Viewr of the:` said container and F1g.'4'^is a transi'ferse sectional viewof the cap `portion of'theshell taken on the is'adaptedto be secured to the inner o r upperfportionof the handle of the structurefrom'-which the material is adaptedfto 'bedi'spensed The handle portion comprisesv the mainr or vbody portion 3 consistingk of: a tubularl shellfthe lower or outer end of whichY is-'screw-threaded, as indicated at 4, with which the upper screw-threaded -portion`5-of an-end cap' is adapted to be engaged. I

'The tubular-shell 3 is provided ywith a circular bead-like-p'ortion 7 with which the inner* or upper endvo the cap 6 is adapted to contact. This bead-like portion projects outwardly beyond the outer surface of the upper. screw-threaded end portion 5 of the cap so that/any 'water which may' run down the side of the `tubular shell portion y3 will not'be aptA tofpass in between 'the portion 5 of` the cap and -theadjacent portion-4 of theff'shell' 3.

Situated-within the shell or handle comprising the yparts Sand 6 is acollapsible cbntainer'IO-the upperfclosed end 11 of whichis; relatively VthickV and is provided with a projection 12. A screwthreaded opening 13 extends through the rupper end 11 of theA container and through lthe pro jection 12.y A screw-threaded tube 15 carried^-by^the inner upper end portion yof the structure extends through said opening. The screw-threads upon the said ltube 15 andI within the opening 13 are left handed so that upon Yturning the container to the rightfthe` inner end thereo'moves downwardly to force the material within the said container into the tube 15 and outwardly into the bristles 1.

The outer end of the conta-incr is closed by means of a closure having a thickened central projecting portion 20 which is adapted to fit into a centrally` situated depression 2l upon the inner side of the outer end of the cap 6. Such depression is formed by pressing the metal outwardly so that a corresponding projection appears on the outer side of said end. The exterior side of the outer end of the cap 6 is provided with an annular projecting portion 22 the inner side of which constitutes a groove upon the interior side of said end of like shape and contour. Interposed between the said projecting portion 22 and the cent-ral outwardly extending portion 28 of the outer end of the cap is an annular groove or depression 24. Situated at intervals within and extending transversely of the interior groove formed by and in opposed relation to the project-ion 22 are wedge-shaped web portions 25 which are adapted to engage and bite into the flangelike lower end portion 28 of the container l0. The inner surface of the depression 2l 'is provided with pointed projections 80 which projections are adapted to engage and bite into the thickened portion 2O of the end ofthe container 10 when such con'- tainer is placed within the hollow shell or handle and the cap 6 screwed into position thereover. Simultaneously the edges of the wedge-shaped webs 25 engage the edges of the iiange-like portions 28 and bite into the same.

It will be understood that in order thatv the pointed projections 30 and the wedgeshaped webs 25 may bite or cut into the portions and wedge-shaped webs will be caused to cut into or indent the said portions of the said container.

It will be apparent, therefore, that I have provided means whereby the outside shell structure of the device is adapted to be positively connected with the lcontainer so that upon rotation of said shell with respect to the head or top portion Vof the structure the container is positively rotated therewithA In this way a positive means is provided for eiecting rotationof the container IO/to thereby insure that the liquid or semiliquid material therein will be expelled therefrom through the tube 15.

Having thus described my invention what I claim and desire to secure by Letters Patent is:

l. A device for' dispensing liquid or semiliquid materials, comprising a shell adapted to receive a container for the material to be dispensed, which shell has a cap at its outer end which is provided with projections which are adapted t0 engage the said container whereby when the said shell is rotated the said container is rotated, and means whereby when the said container is rotated in one direction the material therein is caused to be discharged.

2. A device for dispensing liquid or semiliquid materials, comprising a shell adapted to receive a container for the material to be dispensed, which shell has a cap at its outer end which is provided with projections which are adapted t0 engage the said container whereby when the said shell is rotated the said container is rotated, land a discharge tube'which extends into the saidcontainer with which the said container is` in adjustable engagement whereby when the said shell and container are rotated in one direction collapsing of the said container is effected to cause the discharge of the said material therefrom.

3. A device for dispensing liquid or semiliquid materials, comprising a shell adapted t0 receive a container for the material to be dispensed, which shell comprises a cap havingl a central depression upon its inner side into which a central projection upon the outer end of the said container projects and the bottom of which depression is prof vided with projections which engage the said projection upon the container, and the said cap being provided with `an annular groove upon its inner side across which proj ections extend, which projections are adapted to'engage a peripheral flange upon the said container, engagement of the first and second named projections with the said container being adapted to cause the said shell and `container t0 rotate in unison, and means whereby when the said shell and con-A tainer' are rotated in one direction the ma" terial to be dispensedis discharged from the said container. i i

In testimony, that I claim the foregoing as my invention I have hereunto signed my' name this 8th day of June, 19,22.
