Definitions
- This invention relates to shipping and storing vessels, and While the principles thereof are adaptable to various kinds of vessels for different purposes, it is more particularly intended for use in shipping milk.
- Milk-cans as now constructed are made of tin-plated sheet-iron, and have a reduced neck with a cover which fits within said neck. In removing and replacing the cover much friction is created against the cover and the inside of the neck so that the tinplating soon becomes worn, more especially as the neck becomes somewhat dented and irregular by use. This exposes the iron to rust and discolors the milk, reducing its value and quality. Furthermore, such cans are diflicult to clean, not only because they have crevices in which decomposable matter lodges, but because it is impossible to see the inside when cleaning it.
- I further aim to provide an improved lock or clamp for the cover in conjunction with means for supporting one can upon another in properly alined position.
- My invention comprises the constructions and combinations which will be hereinafter described and particularly set forth in my claims.

- My improved can is of cylindrical shape and the body A is made of only two sheetmetal pieces a and (E, the former being drawn from a plate into cup-shape, and the latter being tubular or cylindrical.
- an annular sheet-metal strip a To the bottom edge of the member a is preferably secured an annular sheet-metal strip a to keep the bottom off the ground and give stability, and it will be observedthat this does not introduce any seam into the inside.
- the union between the members a and a is made by a welded joint a before the metal is plated, thereby eliminating any seamcrack or roughness on the interior of the can at this point.
- a seat a for the cover At the upper end of the can is formed a seat a for the cover, said seat consisting of an annular step increasing the diameter of the portion a above it by half an inch, more or less.
- a roll or like projecting rim a On the upper end of the member a is formed a roll or like projecting rim a which for greater solidity may contain an annular wire a. This completes the can-body.
- the cover B is formed from a single stamping of sheet-metal, pressed into cupshape, the same as the bottom member a and fitting within the enlarged upper portion a of the member A. Near its bottom there is an annular contraction b which forms a seat 6 for an annular sealinggasket C, which may be of rubber or like material, and is held in place by friction or resiliency. It will be seen that the contracted portion Z) has an external diameter slightly less than the internal diameter of the member (f, so that when centrally seated, it does not touch the latter.
- the portion of the cover which lies above the seat 71 and subtends the portion a of the can is also sufficiently less in diameter to leave a narrow open space cl, so that the portion 6 does not at any point touch the portion a when the cover is seated.
- the centering-shoulder may be made in the form of a plurality of separated points 6 which are spaced at intervals around the circumference of a circle on the side-face of the cover and may be formed individually by a punch or calking-tool after the cover has been stamped out in the dies.
- the number of such points theoretically required for centering is three, it is preferable on account of the narrowness of the air-space (Z and the neat fit required to use at least six points, as shown in the drawing.
- This arrangement while involving the same principle of centering the cover, does not have the advantage of the continuous annular shoulder of Fig. 1, that it forms an additional or secondary seal at the upper margin of the can to keep out dust; but again thislatter is hardly necessary, as in practice the roll 5 comes close to the roll a when the can is sealed, and thus itself acts to exclude dust.
- Additional means for hold ing the clamping-device in clamping position may consist of two small bosses f pressed up from the metal of the uprights F in position to engagathe legs of the lever G when it is in the clamping position, as shown in Figs. 2 and 3, it being understood that there is sufficient resiliency in the plates and other parts to enable the lever to snap past the upper boss f in opening.

METAL CONTAINER.
Application filed February 29, 1912.
To all whom it may concern:
Be it known that I, VILLTAM J. IVERNER, of Kiel, Wisconsin, have invented a Metal Container, of which the following is a specification.
This invention relates to shipping and storing vessels, and While the principles thereof are adaptable to various kinds of vessels for different purposes, it is more particularly intended for use in shipping milk.
Milk-cans as now constructed are made of tin-plated sheet-iron, and have a reduced neck with a cover which fits within said neck. In removing and replacing the cover much friction is created against the cover and the inside of the neck so that the tinplating soon becomes worn, more especially as the neck becomes somewhat dented and irregular by use. This exposes the iron to rust and discolors the milk, reducing its value and quality. Furthermore, such cans are diflicult to clean, not only because they have crevices in which decomposable matter lodges, but because it is impossible to see the inside when cleaning it.
It is the object of the present invention to avoid these disadvantages, and more particularly to provide an improved cap or closure which, while giving a perfectly hermetic seal, shall be entirely free from sliding-surfaces between itself and the body of the can, whereby the tin-plating is preserved. a
I further aim to provide an improved lock or clamp for the cover in conjunction with means for supporting one can upon another in properly alined position.
My invention comprises the constructions and combinations which will be hereinafter described and particularly set forth in my claims.
My invention will best be understood from a consideration of the following detailed description of the most improved form there of taken in connection with the accompany ing drawings illustrating the same, and herein- Figure l is a side elevation of a complete can, the right-hand half being shown in median section. and the cover in the released position ready for removal; Fig. 2 is a transverse section at one side of the can on the plan 2, and on a larger scale, showing the cover-clamp in clamping position; Fig. 3 is a plan-view of the cover-clamp and adjacent portions of the can; Fig. 4 is a front Specification of Letters Patent.

elevation thereof from the outside of the can; Fig. 5 is a plan-view of the cover shown in Fig. 1 on a smaller scale and omitting the central air-vent; Fig. 6 is a bottom planview thereof; Fig. 7 is a bottom plan-view of an alternative form of cover; and Fig. 8 is as to the left-hand half an elevation and as to the right-hand half an axial section of this form of cover, omitting the clips.
The reference letters refer each to the same part in each figure of the drawings.
My improved can is of cylindrical shape and the body A is made of only two sheetmetal pieces a and (E, the former being drawn from a plate into cup-shape, and the latter being tubular or cylindrical. To the bottom edge of the member a is preferably secured an annular sheet-metal strip a to keep the bottom off the ground and give stability, and it will be observedthat this does not introduce any seam into the inside. The union between the members a and a is made by a welded joint a before the metal is plated, thereby eliminating any seamcrack or roughness on the interior of the can at this point. At the upper end of the can is formed a seat a for the cover, said seat consisting of an annular step increasing the diameter of the portion a above it by half an inch, more or less. On the upper end of the member a is formed a roll or like projecting rim a which for greater solidity may contain an annular wire a. This completes the can-body.
The cover B is formed from a single stamping of sheet-metal, pressed into cupshape, the same as the bottom member a and fitting within the enlarged upper portion a of the member A. Near its bottom there is an annular contraction b which forms a seat 6 for an annular sealinggasket C, which may be of rubber or like material, and is held in place by friction or resiliency. It will be seen that the contracted portion Z) has an external diameter slightly less than the internal diameter of the member (f, so that when centrally seated, it does not touch the latter. The portion of the cover which lies above the seat 71 and subtends the portion a of the can is also sufficiently less in diameter to leave a narrow open space cl, so that the portion 6 does not at any point touch the portion a when the cover is seated. Opposite the upper edge of the portion a, where it joins with the roll a, there is formed upon the element of my invention, and it is vital to the proper action of the cover, whereby the object previously referred to is attained, of obtaining a substantially tight joint without sliding-surfaces, for be it borne in mind the discoloration of the milk, which is caused by the rust consequent upon the wear produced by such sliding-surfaces, is one of the principal objections to the present can. It will be seen that in placing the cover in the can, the shoulder Z2 merely touches the latter, and does not slide along it, and therefore friction is effectively eliminated eve-n along this line. Moreover, when provided with the clamping-device to be presently described, the contents of the can and body are kept dry abovethe sealing-gasket C, so that rusting cannot take place under ordinary circumstances, even should the plating be worn off. Nevertheless it is not essential to the principle of my invention that the centering-shoulder Z) should be made in a continuous annular form, although this is the simpler and preferable way of making it. In Figs. 7 and 8 I have shown how the centering-shoulder may be made in the form of a plurality of separated points 6 which are spaced at intervals around the circumference of a circle on the side-face of the cover and may be formed individually by a punch or calking-tool after the cover has been stamped out in the dies. lVhile the number of such points theoretically required for centering is three, it is preferable on account of the narrowness of the air-space (Z and the neat fit required to use at least six points, as shown in the drawing. This arrangement, while involving the same principle of centering the cover, does not have the advantage of the continuous annular shoulder of Fig. 1, that it forms an additional or secondary seal at the upper margin of the can to keep out dust; but again thislatter is hardly necessary, as in practice the roll 5 comes close to the roll a when the can is sealed, and thus itself acts to exclude dust.
It should be understood that the form shown in Fig. 7 and that of Fig. 6 are really different forms of the same thing, each embodying a plurality of contact-points or elements, which abut against the inner face or edge of the can, and thus keep the body of the cover out of contact therewith; but in Fig. 6 the number of such points is infinite, whereas in Fig. 7 the number is finite. It is also readily seen that a similar result might be accomplished by making the contactpoints project inwardly from the surface of the container instead of outwardly from that of the cover.
IVhile not deeming it essential to my invention, it may in some cases be convenient or desirable to apply an air-vent to the cover to enable it to be easily raised, this being shown at E, the cover being provided wit-h a tubular threaded nozzle 6 surmounted by a screw-cap 0 To secure the cover in place, various clamping-devices may be used, one of which I have illustrated in the drawing. Upon opposite sides of the cover are mounted two pairs of sheet-metal uprights F, these being secured to the inner side thereof by means of flanges f and rivets f Said uprights have an outwardly projecting overhang f perforated at f to form a pivot-bearing for a bell-crank lever Gr, said lever being formed of a metal rod or wire bent in bail-shaped form in the center, and conveniently pro vided with a cylindrical handle H. The ends of the bell-crank-lever G which project beyond the bearings f are bent at right angles to the pivotal axis, as shown at g, giving a crank of short radius, and beyond that parallel to said axis as at 9 forming journals for the ends of a bail-shaped mem her I, the ends of which are turned around the portions 9 and the latter to hold them in place are upset on the ends as shown at 9 and provided with washers 9 the middle-portion of the bail I, that is to say, the depending legs 2" thereof are hooked as shown at 2' so as to engage the roll a on the edge of the can-body, and it will be seen that the angle of the cranks g is such that when closed the pivots of the bail I are carried slightly over the center, whereby the reaction of the bail tends to keep them in that position. Additional means for hold ing the clamping-device in clamping position may consist of two small bosses f pressed up from the metal of the uprights F in position to engagathe legs of the lever G when it is in the clamping position, as shown in Figs. 2 and 3, it being understood that there is sufficient resiliency in the plates and other parts to enable the lever to snap past the upper boss f in opening. hen the lever G is turned down into the clamping position, it acts to compress the gasket 0 between the seats a and .72 and thereby hermetically seal the can at this point. In releasing the cover it is simply necessary to take hold of the handles and raise them,
which not only unclamps the cover but also rights F each with an inwardly-facing shoulder f, the diametral spacing of these shoulders on opposite sides being equal to or slightly greater than the outer diameter of the bottom strip a whereby any can may be set upon and between these shoulders of another can and will be held thereby in due and proper alinement, in such manner that it cannot fall off. The spacing of the two uprights F of each side is sufficiently far to make other support in most cases unnecessary; but should there be found a tendency of the cans to fall over sidewise, as where they are subject to jarring and shaking in transportation, I may provide additional uprights F located on the inner margin of the cover midway between those heretofore described, as shown in Fig. 1 in the center, the same being provided with similar shoulders which will prevent such tendency to tip side-wise. It will be understood, of course that the provision of this shoulder is not essential to the general principles of my improved cover as hereinabove described.
Although I have described my invention as applied to a metallic milk-can, it will be understood by those skilled in the art that some of the principles may be also applied to vessels of other material and for other purposes.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

A container or vessel of cylindrical form having an enlarged internal diameter in its upper part separated from the main diameter by an annular shoulder, a cover fitting within said enlarged internal diameter and having on its lower edge an annular seat, and a compressible packing-ring between said shoulder and seat, said cover being adapted to be depressed so as to compress said packing-ring; said cover having further the upper portion of its outer surface of the same diameter as the internal surface of said enlarged diameter of the container so as to abut thereagainst, and its lower external surface of less diameter so as to be at all times out of contact with said container; the upper larger-diametered portion of said cover forming thereby a secondary seal or closure.
18. A container or vessel of cylindrical form having an enlarged internal diameter in its upper part separated from the main diameter by an annular shoulder, a cover fitting within said enlarged internal diameter and having on its lower edge an annular seat, and a compressible packing-ring between said shoulder and seat, said cover being adapted to be depressed so as to compress said packing-ring; said cover having further the upper portion of its outer sur-- face of the same diameter as the internal surface of said enlarged diameter of the container so as to abut thereagainst, and its lower external surface of less diameter so as to be at all times out of contact with said container; the upper larger diametered portion of said cover forming thereby a secondary seal or closure; said container having further on its upper edge an outwardly turned roll and said cover on its upper edge also an outwardly turned rim, which when said cover is depressed upon said packing-ring comes approximately into contact with said roll thereby forming a tertiary closure.
19. A container or vessel of cylindrical form having an enlarged internal diameter in its upper part separated from the main diameter by an annular shoulder, a cover fitting Within said enlarged internal upper portion and having at its lower edge an annular seat, a compressible packing-ring disposed between said seat and shoulder and adapted to be compressed between them, the external diameter of said cover being sufficiently less than said enlarged internal diameter of the container to be at all times out of contact therewith when properly cen tered; and outwardly turned rims on the upper edges of the cover and container respectively, said rims being adapted to come into approximate contact along a circular line when the cover is in place, and thus form a secondary closure; said cover and container having mutually contacting ele ments which act to center the cover within the enlarged upper portion of said contamer.
In witness whereof I have hereunto set my hand in the presence of two witnesses.
