Application August 29,

6 Claims.

The invention pertains to containers especially adapted for use as butter tubs, and has for its general aim the provision of a butter tub of improved construction which permits of economical manufacture, which facilitates shipment of the tubs, and which is capable of preserving the contents thereof in a sanitary condition.

With this aim in View, one object of the invention is to provide a novel construction for butter tubs permitting the use of light weight materials without sacrificing strength and rigidity, and permitting the nesting of both the body and cover sections for the sake of compactness in shipping. l

Another object is to provide an improved construction for the upper end portion of the tub adapted to insure a tight fit of the cover on the body.

The objects of the invention thus set forth, together with other and ancillary advantages, are attained by the construction and arrangement illustrated in the accompanying drawing forming a part hereof, in which:

Figure 1 is a side elevational view of a tub embodying my invention. Y

Fig. 2 is a fragmentary Vertical sectional View through one side of the tub.

Fig. 3 is a fragmentary transverse sectional view taken in the plane of line 3 3 of Fig. 2.

Fig. 4 isla side edge view of a fastening device for the cover.

The improved tub comprises a main or body section having an annular side wall 'I and a bottom wall 8 with metallic reinforcing hoops 9 and l0 at the lower and upper ends of the side wall; and a cover section comprising a top plate 11 having at its outer peripheral edge an annular ring 12 with a tapering flange 13 adapted to telescope the upper hoop 10.

The side wall 7 of the body section is preferably made of a light fibrous material such as that commonly known as ply-wood. It is made from two or more sheets rolled into annular form with the overlapping ends suitably secured together. To permit of the nesting of a plurality of body sections together during shipment, the side wall ofthe tub is flared or tapered outwardly and upwardly from its lower end.

In securing the bottom wall 8 in position, advantage is taken of the tapering character of the ide wall 7 to insure a tight seal for the bottom of the tub. To attain this result, the bottom wall is made of substantial thickness so as to insure the necessary rigidity, and its peripheral edge, which is of a diameter slightly greater .than that 1932, Serial No. 630,810

of the side wall at the final point of engagement therewith, is tapered as indicated at 15 so as to conform substantially to the taper oi the side wall. Moreover the hoop 9 is first applied to the lower end of the side wall in snugly fitting relation thereto, so as-to provide in effect an annular outer abutment in opposed relation to the peripheral edge of the bottom wall. Thus it will be apparent that when the bottom wall is pressed into position with the application of considerable force, as for instance by hydraulic pressure, a wedging action occurs between the side wall and the edge of the bottom wall causing the lower end of the side wall to be clamped tightly between the hoop 9 and the bottom wall.

To form a stop or abutment definitely limiting the downward movement of the bottom wall, the hoop 9 is made from a metallic strip of substantial width and its lower edge portion is turned inwardly and upwardly as at 16 to form an annular shoulder 17. Such inturned portion of the hoop also serves to increase the effectiveness thereof as an abutment in the clamping action above referred to.

The upper hoop 10 is also made from a fiat metallic strip of substantial width, and is especially shaped to provide a lower annular fastening band 18 fitting snugly about the upper end of the side wall in spaced relation to the upper end thereof; a top flange 19 overlying the upper end of the side wall so as to form a smooth seat for the cover plate 11; and an intermediate seating rim 20 flaring or tapering outwardly and downwardly and bearing at its upper edge against the upper outer edge of the side wall. The lower edge of the seating rim 20 being spaced outwardly from the side wall is connected to the fasening band 18 by an annular portion 21 which constitutes in effect an annular strut supporting the lower edge of the seating rim against inwardly directed presn sure. The hoop is secured in position on the side wall by piercing indentations 22 therein at spaced points, thus eliminating the use of nails.

The cover plate 11 is also preferably made of ply-wood, and is made of a diameter such that its outer lower edge portion is adapted to rest upon the top seating ange 19 of the upper hoop 10. .An annular groove 23 formed in the outer peripheral edge of the cover plate is adapted to receive loosely the ring 12 carrying the cover flange 13.

The ring 12 and cover flange 13 are formed from a flat strip of metal, with the ange bent downwardly from the outer edge of the ring at an angle such as to produce an outwardly and downwardly tapering surface substantially conforming to the outward and downward taper of the seating riin 20. By this construction a wedging action is produced between the cover ange 13 and the seating rim 20 which insures a tight sealing fit between the cover and the body of the container, it being observed in this connection that the sealing is iirrnly supported by the annular strut 2i and by engagement at its upper edge with the upper outer edge of the side wall. At the saine tiine the inward pressure on the seating rim is transmitted through the annular strut 2l to force the fastening band i8 tightly about the side wall of the container. A feature of primary importance is the outward flaring character of the cover flange which permits a plurality of covers to be nested together in compact relation for shipment.

If desired, the cover inay be fastened in position on the body by rneans of a plurality of fastening devices in the form of metallic strips 24, the lower ends of which are inserted between the fastening band 18 of the top hoop lo and the side wall 7 before the cover is applied. With the strips thus engaged with the hoop l0, they are bent upwardly and over the upper outer edge of the cover plate and fastened thereto as by means of tacks 25. The latter are preferably inserted through inwardly folded portions 26 with the heads of the tacks concealed and retained within the folds.

I clairn as my invention:

l. A butter tub having a body section with an annular side wail tapering outwardly and upwardly from its lower end, a reinforcing hoop encircling the upper end of the side wall and shaped to provide a top fiange overlying the upper end of the side wall, an outwardly and downwardly tapering seating rim and an annular strut interposed between the lower end of the seating rim and the side wall of the container; and a cover section having a peripheral fia-nge tapering outwardly and downwardly for engagement with K said seating rirn.

2. A butter tub having a body section with an annular side wall tapering outwardly and upwardly from its lower end, a reinforcing hoop encircling the upper end of the side wall and shaped to provide an outwardly and downwardly tapering seating rini, a fastening band fitting snugly about the side wall at a point spaced from its upper end, and an annular strut interposed between the lower edge of said seating riin and the fastening band; and a cover section having an annular fiange tapering outwardly and downwardly for engagement with said seating rim.

3. A butter tub having a body section with an annular side wall tapering outwardly and upwardly from its lower end, a reinforcing hoop encircling the upper end of the side wall and shaped to provide an outwardly and downwardly tapering seating rim with its upper edge bearing against the upper outer edge of the side wall, a fastening band fitting snugly about the seating rim at a point spaced from its upper end, and an annular strut interposed between the lower edge of said seating rim and the fastening band; and a cover section having an annular flange tapering outwardly and downwardly for engagement with said seating rim.
