"WALTER L. RUTKOWSKI, OF ST. LOUIS, MISSOURI, ASSIGNOR TO B. 0. CAN COMPANY,

OF ST. LOUIS, MISSOURI, A CORIORATIO N OF MISSOURI.

rownnn CAN.

Application filed November 19, 1923. Serial No. 675,515.

My invention relates to cans and tubes,

either paper, fiber or metal, and, more par-,

ticularly to the top cover thereof, and, it is a distinct and practical improvement to F overcome certain practical objections to, and

defects in paper or fiber cans and tubes having metallic covers, or tops.

An object of my present invention is to,

provide a can or tube of the above class which can be fille'dthough the top and then have the cover applied thereto, thus obviating filling through the bottom and employing a crimping machine.

A further object of the invention is to provide a metallic top or cover forcans and tubes having no 'inner marginal edge to obstruct the free flow of all contents from the can or tube, thus obviating the necessity of having to unduly shake the can to remove the last of its contents.

A still further object of the invention is to provide a friction sifter top, or cover .which can be easily applied and removed from the friction ring of the can or tube.

With the above and other objects in view, the invention consists in the novel features of construction, arrangement and combination of parts hereinafter described and finally pointed out in the appended claims.

Referring to the accompanying drawings forming a part of this specification, wherein like characters of reference denote similar parts throughout the several views:

1, is a vertical sectional view of a can embodying the features of my invention.

Fig. 2, is a vertical sectional view of the friction ring before being applied to the can.

Fig. 3, is a top plan view of the can with the closure thereof provided with a multiplicity of sifter openings.

Fig. 4, is a top plan view ofthe can with the closure thereof provided with a plurality of relatively large openings.

Fig. 5, is a top plan view of the can with the closure thereof provided with one large opening and a plurality of smaller openings;

Referring to the drawings, 1 represents a suitable metallic paper or fiber can or tube which may be of any shape desired, such for instance, as round, square, oval, etc. and of any size desired.

A suitableclosure is applied to the lower end of the can and is illustrated as comprising a metallic disk 2 which is preferably dished and provided with the annular flange 3 to engage the inner face of the tube and the curved outer portion 4 which is rolled so as to cause the free edge to be seated in the outer face of the paper or fiber can thereby securely clamping the'bottom 2 to the body 1.-

lar ring body 5 engages the inner face of the can body 1 and the flange 6 is rolled, as at 7, so asto cause the peripheral edge thereof to embed itself into the material of the can body to securely hold the ring in position at the upper end of the can. The outer face of the tubular ring body 5 is also rolled into frictional contact withthe inner surface of the can body so as to be substantially flush therewith, thereby obviating raw edges and obstructions to the free flow of contents of the can.

I further employ a friction cap having the tubular open bottomed neck 8 terminating at its'upper end in an outwardly dished or curved peripheral bead 9. The bead 9 terminates in an upwardly dished or curved crown top 10 which is provided with a plurality of suitable sized perforations or openings 11. The cap is frictionally applied to the ring by pushing the tubular neck 8 there-- of into the opening of the friction ring and into frictional contact with the body 5 thereof, as clearly shown in Fig. 1.

I still further employ a rotatable cover member having a raised or upwardly dished top or crown section 12 which terminates at its periphery edge in an annular laterally directed curved flange 13 which engages the laterally directed peripheral bead portion 9 of the removable friction cap. The top section 12 of the rotatable. cover member is preferably provided with a plurality of suitable sized perforations 14: of the same size as the perforations or openings 11 of the friction cap for-controlling the perforations 11 thereof. Where the perforations in the cover member are oftwo different sizes as indicated by the reference characters 15 and 16 in Fig. 5, I employ only one large opening 17 in the friction cap, as shown in Fig. 5, so thatthe contents can be either poured .out of the can through the single opening 15 or sifted out through the plurality of openings 16, as is manifest.

The many advantages of the herein described invention will readily suggest themselves to those skilled in the art to which it appertains.

I do not wish to be understood as having limited myself to the details of construction shown and described, but desire to have it understood that the invention I have shown in the drawings is merely illustrative,

as it is manifest that various minor changes may be made in the exact construction andparticular arrangement of parts without departing from the spirit of my invention, hence I reserve the right to make any such changes, ormodifications, as may fairly fall within the scope of the appended-claims when fairly construed.

What I claim 1s: v v

1. In a can construction, in combination, a fibrous tubular body closed at its lower end, a metallic sleeve ring having a peripheral upper edge fixed to the upper end of the tubular body by rolling the peripheral edge of the ring into engagement with the tubular'body, the lower edge of said ring terminating at a point below the upper edge of the tubular body and disposed within the body, a closure member having a contracted downwardly directed neck for frictional contact with the inner. face of the metallic sleeve ring and having its lower edge terminating adjacent the lower edge of the sleeve ring and within the body.

2. In a can construction, in combination,

of the ring with the lowerf'edge of said neck I terminating adjacent the lower edge of'said ring and a perforated rotatable cover member for said cap member.

In testimony whereof, I have hereunto signed my name to the specification.

WALTER L. RUTKOWSKI.
