UNITED STATES PATENT OFFICE ROTARY SPREADER George E. Carlson, Chicago, Ill., minor to Carlson Research Corporation, Chicago, 111., a corporation of Illinois Application December 1, 1933, Serial No. 700,382 'I Claims. (Cl. ill-67.4)

Thisinvention relates to receptacles for ma,- length of the roller. Preferably, the roller is terials of a pastyconsistency, such as shaving formed with depressions or grooves, seen at H! cream or cold cream, and it is particularly conin Figure 3, and the material discharged from the cemed with providing such receptacles with tube is picked up by these grooves as the roller means for spreading the pasty material as it is turns past the discharge slot, 9. 5 discharged from the receptacle. It consists of Rotation of the roller is, of course, produced certain features and. elements of construction by causing it to traverse the face or other porherein shown and described, as indicated by the tion of the body upon which the contents of the claims. tube. I, is to be spread. The roller shown in In the drawings: Figures 1, 2 and 8 is considered of suitable form 10 Figure l is a top plan view, and Figure 2 is for spreading shaving cream over the cheeks and a side elevation of a collapsible tube fitted with chin. It is 01' generally cylindrical form, with a special terminal at its discharge end, including a slightly bulging contour.

Instead of the usual closure cap this invention in which the collapsible tube or con- 40 invention provides a terminal fitting, 3, threaded tainer, 20, includes a specially formed end wall, tofit the neck, 2,and formed withaconical coun- 2|, provided with upstanding ears or lugs, 22, ter-bore in its lower end at 4 to seat against which support a pin, 23, on which a spreader the conical upper end, 5, of the tube, I. roller, 24, is journaled. Thus the supporting The upper portion of the fitting, 3, provides fitting for the roller is made integral with the upstanding ears, 6, which support a pin, 1, on receptacle. The roller, 24, may be of any suitwhich isv journaled the spreader roller, 8, whose able form, depending on the use to which the function is to distribute the contents of the tube. material in the tube, 20, is to be put, and may be as desired.

The discharge whose longer dimension extends parallel to the orifice, 26, in the end wall, 2i, leads directly to axis of the roller, 8, so that the paste or cream the roller, 24, and may be either circular or obdischarged from the neck of the tube will be aplong in cross-section. If desired, the tube may plied directly to a substantial portion of the be provided withadust cap, 21, whichisshownas 55 fitting snugly over the cylindricai body oi the tube, and completely enclosing the terminal, 2!, and the roller, 24, carried thereby,

In Figure 7 the spreading roller, 30, is shown as being disposed with its axis aligned with the axis of the bore,'3|, in the threaded discharge neck, 32, of the tube, 33. A terminal block or fitting, 34, is screwed onto the neck, 82, and clamps against the end of said neck the flange, 35, of a bushing, 38, which projects from the upper end of the block, 24, and serves as one bearing on which the holiow roller, 30, rotates. The other end of the roller is provided with a trunnion, 31, and a ball, 38, supported on the block, 34, provides a bearing, 39, for said trunnion. The block, 34, is notched at diametrically opposite points to receive the lower ends of the bail, 38, as that the outwardly turned foot-pieces, 40, of the bail, may be clamped under a securing ring, 4 i, serewed onto the upper end of the block, 34. This forms a convenient mode of assembly, and permits the device to be taken apart readily ii it is desired to cleanse the interior of the hollow spreading roller, 36. The surface of the roller is perforated, as seen at 42, for discharging the cream or paste which reaches the cavity of the roller through the outlet, 3!, and the bushing, 86.

While there are shown and described herein certain specific structures embodying the in-' vention, it will be manifest to those skilled in the art that further modifications and re-arrangements of the parts may be made without departing from the spirit and the scope of the invention, and that the same is not limited to the particular forms herein shown and described, except in so far as indicated by the appended claims.

I claim:

1. A spreader including a receptacle having a discharge orifice, a roller mounted for rotation adjacent the orifice to receive material'on its surface, and a support in which the roller is mounted having cheeks closely fitting against the ends of the roller with curved surfaces sur rounding the orifice and adjoining said cheeks, said surfaces conforming closely to the curved side portions of the roller between its ends and the area exposed to the orifice.

2. A spreader including a receptacle, a sup= port associated'therewith and a roller mounted for rotation in the support, the support having an orifice leading from the interior of the re= ceptacle to the surface of the roller, and having curved surfaces surrounding the orifice and conforming closely to the curved contour of the roller I adjacent the area exposed to the orifice.

3. A spreader including a receptacle having a threaded neck, a support formed with an orifice extending through it and threaded at one end to engage the threaded neck ef the receptacle,

portion of its area exposed to the orifice serving as a clesure therefor, the support having curved surfaces adjoining the orifice and conforming closely to the curved contour of the roller beyond its area exposed to the orifice, whereby the ma= terial may be fed to the surface of the roller by collapse of the tube and distributed from the roller by rotation of the latter.

5. A spreader including a receptacle, a sup= port associated therewith and a roller mounted for rotation in the support, said support having an orifice leading from the interior oi the receptacle to the surface of the roller, said roller having a plurality of depressic-ns in its surface spaced apart circumferentially, and the support having curved surfaces conforming closely to the curved contour of the roller and extending from both sides of the orifice circumferentially by more than the width of one depression.

6. A spreader including a receptacle, a support associated therewith and a roller mounted for rotation in the support, said support having an orifice leading from the interior of the receptacle to the surface of the roller, said roller having longitudinally extending grooves terminating inwardly from its ends, and the support having curved surfaces surrounding the orifice and conforming close to the curved contour of the roller between its ends and the ends of the grooves whereby the roller serves as a closure for the orifice.

7. spreader including a receptacle, a support associated therewith and a roller mounted for rotation in the support, said support having an orifice leading from the interior'of the receptacle to the surface of the roller, said roiier having longitudinally extending grooves terminating inwardly from its ends and spaced apart circumferentially, and the support having cheeks closely fitting against the ends of theroller with curved surfaces adjoining said cheeks conforming closely to the curved end portions of the roller between its ends and the ends of the grooves, said curved surfaces extending circumferentially at both sides of the orifice by more than the width of one groove whereby the roller serves as a closure for the orifice and the grooves act to receive material from the orifice for distributing it when the roller is rotated.
