6 Claims. (Cl. 220-66) This invention relates broadly to containers, and more particularly to shipping and dispensing containers of relatively light gauge and small size as distinguished from large heavy barrels and drums. It relates still more particularly to sheet metal shipping and dispensing containers of such size and shape as to be adapted when filled to be carried by one person.-
Although the invention is not as to certain fea 19 tures thereof so limited, it is especially well adapted for sheet metal shipping and dispensing containers of the type which are adapted when filled to be carried by one person by a handle positioned when operative substantially in line with .the axis of the container. Containers of this type are used in sizes ranging up to and above in the neighborhood of ten gallons, perhaps the most popular size being five gallons.
Such containers are made of relatively light 20 gauge sheet metal as distinguished from the metal used for making large size barrels and drums of, say, 100 gallons capacity. The containers must be strong, particularly when used for shipping, not only to insure against damage in 25 handling but also because of the extremely rigid shipping container specifications of the regulations of the Interstate Commerce Commission. Moreover, containers of this type must be relatively inexpensive to manufacture as they are in a 30 highly competitive field.
Shipping and dispensing containers of the sizes with which the present invention is primarily concerned are ordin'arily provided either with imperforate tops or covers which are removable as 35 a whole or with tops or covers either removable 45 Containers of the type in question-are being used more and more widely for the shipping and dispensing of different substances, liquid, viscous,
plastic and solid. In certain cases it is necessary in preliminarily treating the contents of the con- 5 tainer before dispensing or in dispensing the contents to have access thereto such as is not aii'orded by the usual pouring opening, and yet in many cases it is undesirable'to haveto remove the en- ,tire cover. In certain 'cases it is not desirable to use a full open top container, and in such cases signed as to withstand very rough usage.
the only opening is the relatively small pouring opening.
For example, in'the shipping and dispensing of products such as highly viscous cements and cer- I tain food products it is not possible to use a container having a non-removable top and a small pouring opening. It is undesirable to use a full open top container due to the great weight of the contents of the container and the inherent weakness of containers of this type. Yet it is necessary 10 to have access to the contents of the container either for stirring or in order that the contents may be removed, Consequently the containers of the type above mentioned which have heretofore been available have not been adapted for the shipping and dispensing of products of the character mentioned.
I provide a container of the type above discussed which is adapted for the shipping and dispensing of products to which access must be had while in the container but which does not require removal of the entire top of the container. My container maybe of the full open top type or it may be of the non-removable top type, the
latter being preferred in most instances due to its superior strength. I make provision for access to the interior of the container, as for stirring, or for removal of the contents otherwise than by pouring, and at the same time I provide a structure which is strong and rugged and which meets the Interstate Commerce Commission regulations.
I provide a container of such size and capacity as to be adapted when filled to be carried by one person, as, for example, by a handle positioned when operative substantially in line with" thef axis of the container and having an opening of relatively large size which may be opened and closed at will, the whole structure being so de- The diameter of the opening is preferably equal to 4 0 at least about one-fourth of the greatest transverse dimension of the top portion of the container. For certain purposes an opening having a diameter equal to at least about one-third of the greatest transverse dimension of the top portion of the container is desirable. Ordinarily the diameter of the opening will not be. greater than about one-half of the greatest transverse dimension of the top portion, as if it is substantially greater than this the container begins to have the disadvantages of a full open top container.
In the ordinary sizes of my container, as, for example, in the 5-gallon size, the opening is large enough to admit a-human hand of average size.
Preferably the opening is large enough to admit a mans hand with sufficient clearance to enable working within the container, as in stirring or' mixing the contents thereof or removing such contents as by the use of an implement such as a large spoon or the like.
I also preferably'provide for pouring out of the container, in case this should be possible or desirable, by providing the opening eccentric with respect to the top portion thereof and extending to a point close to'one edge of the top portion. I further preferably provide for stacking of the container by providing a top stacking surface which extends at least substantially as high as the opening and the closure means therefor, an outage space being provided thereunder. The opening is preferably formed in a sunken portion of the top and such sunken portion preferably communicates with an edge of the top so that liquid will not accumulate therein but will drain off, The handle by which the container is carried is preferably fastened to the top within the movement relative to the top of the container,
being movable to a position when not in use in which it extends upwardly not substantially higher than the upper surface of the top.
The opening is preferably closed by a separate closure member of exceptional strength. The opening may be formed with an upwardly projecting beaded neck and in such case the closure member "has a portion overlying such neck, a gasket being provided therebetween, and the neck and closure member are preferably maintained in assembly by a. clamping ring. The closure member is preferably convexly formed inwardly of the container which adapts it to withstand the shocks to which the container is subjected in use and also does not interfere with stacking. The clamping ring has a number of novel features which adapt it for use particularly with a container of the type in question, the opening in which is much smaller than the usual opening whose closure member is held in place by a clamping ring.
My invention also comprises other subsidiary.
features contributing toward the usefulness thereof for the purpose intended and which, together with further details, objects and advantages thereof, will become apparent as the following description of a present preferred embodiment of the invention proceeds.
In the accompanying drawings I have shown a certain present preferred embodiment of the invention, in which Figure 1 is a perspective view of a. shipping and dispensing container;

Figure 8 is a transverse cross-sectional view taken on the line VIIIVIII of Figure '7; and
Figure 9 is a transverse cross-sectional view taken on the line IX-IX of Figure 7.
Referring now more particularly to the drawings, there is shown therein a 5-gallon shipping and dispensing container made out of light gauge sheet metal. The container comprises a substantially cylindrical body portion 2 having seamed thereto at 3 a raised bottom 4. The container body is provided near its top and bottom with raised annular strengthening and protective portions -5 which may, if desired, be used as rolling rings. Seamed to the upper extremity of the body at 8 is a cover or top designated generally by reference numeral I. The container as thus illustrated is of the non-removable top type, although the top may be made removable if desired. For example, a cover provided with the conventional attaching lugs may be used, the container body in such case having at its top a portion forreception of the cover and attachment'of the lugs, a. suitable gasket being used between the body and cover.
The top of the containerhas a substantially flat upper surface portion designated by reference numeral 8, an intermediate portion 9 and a lower portion Ill. The lower portion [0 communicates with the edge of the container, as
clearly shown in Figure 1, to allow drainage of liquid therefrom. Connected with the intermediate portion 9 .of the top by means of bearings ll. riveted or bolted to the top at I! is a handle I 3 by which the container is adapted to be carried. Dueto the size, shape and capacity of the container it. may be carried by a man by the handle l3 held in one hand. The handle is swingable about the bearings to an upward or operative position in which it is substantially in line with the axis of the container. The bearings .II are centered substantially on a diameter of the container but equidistant from the axis thereof. When the handle I3 is not in use it may be turned down to the position shown in the drawings in which its upper portion is not substantially higher than the portion 8 of the 'top.,
In the embodiment shown in the drawings the handle lies below the portion 8 of the top.
In the lower portion III of the top I is an opening ll surrounded by an upwardly drawn neck I 5, the .upper extremity of which is reversely turned as shown at llito provide a rim in the form of a. bead or lip. In the embodiment shown the rim I8 is below the level of the surface portion 8 of the container .top. The opening II is eccentric with respect to the top of the container and is positioned adjacent the edge thereof as 'shown in the drawings, so that if desired it may conveniently be used for pouring out the contents of the container. The diameter of the opening I l is preferably equal to at least about one-fourth of the diameter r of the top I. The diameter of the opening is preferably not substantially greater than about one-half of the diameter of the top. For certain purposes I find it desirable toprovide an opening whose diameter is equal to in the neighbor hood of one-third the diameter of the top. In
the embodiment shown in the drawings the diameter of the opening I! is equal-to between onehalf and one-third the diameter ofthe top of the container. The opening is preferably made large enough to admit a man's hand and, particularly- 2,120,487 in sizes commensurate with that shown in the drawings; I prefer that the diameter of the opening shall be at least about 4" and not greater than about 7". The opening is of such size as to permit ready access to theinterior of the container, as for mixing or stirring the contents thereof, or for removing the contents otherwise than by pouring.
The outwardly drawn neck I5 is made strong enough to withstand the stresses to which it is subjected in use; It is further strengthened, as
is the top of the container as a whole, by a closure ber, as well as to the container top when the closure member is in position, and avoids an upward projection which would preventstacking. Moreover, the convex curvature of the closure member inwardly of the container better withstands pressures which may be built up within the container.
The rim of the closure member I1 is down-- wardly cupped as shown in Figure 2 so as to cooperate with and lie over'the rim 16. The centaining device, preferably in the form of a clamp- V ing ring designated generally by reference numeral i9, and which is described and claimed in my copending application Serial No. 111,896, filed November 20, 1936, which application is a division of this application. The clamping ring comprises a body portion 20 which is expansible and con-.
tractibleand arranged substantially in the arc of a circle. The clamping ring as a whole is of substantially U-shaped cross section. However, at intervals therealong recesses 2] are cut into the leg portions of the U to provide for suflicient flexibility of the ring substantially inits planefor expansion and contraction thereof necessary in applying and removing it. The upper and lower legs of the .ring are preferably recessed complementarily. Intermediate the recessed portions of the ring are outwardly pressed stifiening and strengthening ribs 22 for imparting to the ring a desired strength and rigidity substantially normal to the plane thereof and to insure proper and sustained cooperation between the container neck and the closure member to hold the closure member in place with the desired pressure. A transverse cross section through the ring at a recessed portion thereof is shown in Figure 8, and a transverse cross section at a strengthened portion thereof is shown in Figure 9.
At the ends of the ring body 20 are outwardly and reversely turned straps 23, the ends of which may be welded, riveted or otherwise connected with the ring body whereby to provide bearings, preferably offset outwardly from the ring body as shown in Figure 4. Pivotally connected with one of the bearings is a link 24 (see Figure 6) which 1 and 4).
is hollow, comprising two legs 25 and an end bearing portion 26 adapted to lie within the strap bearing on the ring body. Each of the legs 25 is provided with a hole 21 for reception of a pivot pin.
There is provided anoperating member designated generally by reference numeral 28 (see Figure 5) which is elongated to provide a handle portion 29 by which the clamping ring is operated. At the opposite end of the member 28 the material thereof is laterally and then reversely turned as shown in Figure 5, and a pivot 30 is provided between the opposed portions of the .1 operating member which passes through the strap bearing23 opposite that engaged by the link 24. Substantially in transverse alignment with'the pivot 30 the member 28 has opposed holes 3| throughwhich and through the holes 21 of the link 24 passes a..pin or rivet 32. Inter- 'mediate the handle portion of the member 28 and the portion havingthe pivotal connections just described the material of. such member is bent upwardly as shown at 33 to allow the member properly to cooperate with the ring in opening and closing movements.
The clamping ring is shown in open or inoperative position in Figure 4. When in such position it may be removedfrom the closure member and container neck and replaced thereon at will. When the clamping ring is being applied it is put in place as shown in Figure 4. The handle 29 is then turned in the clockwise direction about the pivot 30, viewing Figured, through substantially During such rotative movement of the handle the pivot 32 moves around the pivot 30, the portion 3| of the member 28* which lies between the pivots 30 and 32 passing within the hollow'link 24 as shown in Figure 3. The axis of the pivot 30 moves to a position somewhat beyond a straight line between the axis of the pivot 32 and the axis of the lower bearing 23, viewing Figure 1, to conteract the tendency of the ring to.
1 extends transversely of the ring and preferably substantially diametrically thereacross as shown in Figure 3.. Connected with the body of the ring intermediate the extremities thereof is an integral inwardly projecting lug 35 having at opposite sides downward projections 33 (see Figures When the handle 29 approaches the lug 35 it is pressed lightly downwardly, or toward the container, and the outer end of the handle springs under the lug 35. When the outer end of the handle is positioned intermediate the projections 36 it is released'and resiliently moves upwardly so as to lie against the under surface of the lug 35 and between the projections 36 where it is latched in place. The upwardly bent portion 33 of the member 28 allows the handle 29 to move into latched position under the lug 35 as above explained, a portion of the ring lying v ring and into latched position with the end of the handle under the lug 35. The lug 35 has a hole 31 therethrough and the end of the handle has a hole .33 therethrough, which holes assume superposed relation when the handle is in latched position and are adapted to receive any suitable sealing means such as a sealing wire or padlock.
The container is ideally suited for shipping, being exceptionally strong and rugged, easy to handle and capable of being stacked, as indicated in Figure 2. Access may be had to its interior through the relatively largeopening l4 and. the exceptionally strong closure member'and clamping ring structure materially assist when applied in strengthening the top of the container. The container is suitable for uses which similar shipping 'containers of like size heretofore available are totally unsuited.
