DISFENSING CGNTAINER FOR PASTE SHOE POLISH.

Application led December 13, 1927. Serial No. 239,755.

rlhis invention relates to dispensing con tainers for paste shoe polish and more par; ticularly to that type of container for paste shoe polish, wherein the contents of the container are dispensed by a piston which is caused to travel longitudinally of t-hecylinder by a rotating screw.

An important object of the invention is to provide a construction such that the use of grooves or ribs upon the container wall coacting with ribs or lgrooves upon the piston or its follower is eliminated.

A further and more specific object ofthe invention is to provide a piston follower for use in containers of this type which, by its coaction with the walls of the container, is

held against4 rotation without any previouspreparation of the container.

'Ihese and other objects I attain by the construct-ion shown in the accompanying drawing/wherein for the purpose of illustration is shown a preferred embodiment of 'my invention and wherein :f-

Figure 1 is a vertical sectional view through a paste polish applier constructed in accordance with" my invention;

Figure 2 is a section on the line 22 of Figure 1; i

Figure 3 is a side elevation of the piston and follower removed;

Figure 4 is an eldarged plan view of the follower showing one of the guiding elements. i

Referring now more particularly to the drawing, the numeral 10 indicates a container adapted to contain liquid polish and having at one end an applying pad 11 and at. its opposite end a cap 12, which may be either permanently secured to the container or removablyconnected therewith. Rotatably direc-ted through this cap is a shaft 13 having a collar or enlargement 14, preventing its passage through the opening of the cap. Exteriorly of the cap, the shaft-has ap-l plied thereto a nut or finger grip 15, it maybe rot-ated Below the enlargement, the shaft is threaded and is directed through a member 16. This member has engagement with a piston 17 which, in turn, abuts the contents of the container.

The member 16 performs the functions of the ordinary follower and in accordance with my invention, I provide upon the ends of this member blades 17', which extend in the whereby direction of the-longitudinal axis of the con- -VV tainer and have their outer faces sharpened and spaced apart a distance slightly greater Y,

of course, be understood that if the shaft 13 be rotated, the member -16 will be advanced thereon and in its advance, will force before it the piston acting upon the contents.

A device of this character may be ver readily produced and because of the fact that no particular alignment of the casing and follower is necessary, maybe very quickly and readily assembled. As the construction hereinbefore set forth 1s capable of a certain range of change and modification without materially departing from the spirit of the invention, I do not limit myself to such-specific structure eX- cept as hereinafter claimed.

`1. In a dispensing container for shoe polish and the like, a casing having a cap at one end, a shaft rotatable in the cap and extending longitudinally of the casing, means holdingthe shaft against longitudinal movement with relation to the cap, a piston within the casing, a member having engagement with the piston whereby the' piston shifts with the member as the member moves in one direct-ion, the shaft being threaded through the member, the member having means engaging the wall of the casing a portion of which coactswith the inner faces of the wall to form a non-perforating groove therein as the member is advanced in the casing and other portions of which operate in said groove.

2. In a dispensing container for shoe polish and the like, a casing having a cap at one end, a shaft rotatable in the cap and extending longitudinally of the casing, means holding the shaft against longitudinal movement with relation to the cap, a piston within the casing, a member having engagement with the piston whereby the piston shifts with the member as the member moves in one direction, the shaft being threaded through the member, the member having a blade forcibly engaging the interior wall of the casing without erforating the. same, said blade extending ongitudinallj7 of the casing.

3. In combination with a piston, of a tubular dispensing container,'a follower for the .piston having' diametrically opposed knife blades, the edges of which substantially parallel the axis of the' container and are spaced apart a distance slightly greater than the internal diameter of the container and less than the external diameter of the container.

' 4. The combination with a tubular dispensing container, a piston therefor, of means i for advancing the piston cornprsinr a rotatable element, a member engaging tbe piston advanced by rotation of the element and portions upon the element having knife edges paralleling the axis of the element and spaced apart a distance slightly greater than the diameter of the casing, lsaid portions grooving Without slitting the` Walls of the container,

In testimony whereof I- hereunto affix my signature.
