' which the following is a specification.

This invention relates to an improvement in paper walled vessels, the same being specially adapted for containing fresh milk, and in which the milk may be processed or sterilized.

lhe invention consists in the novel parts and devices hereinafter more fully set forth and made the subject matter of claim.

In the accompanying drawing which forms a art of this specification, Figure 1 is a vertical section of a milk delivery can made in accordance with my invention;

Fig. 2, a cross section of the same on the line 2-2 of Fig. 1; Fig. 3,upon a smaller scale,-is a flat view of the blank from which the can body is formed; Fig. 4, a section of said blank; and Fig. 5,upon a greatly enlarged scale,-is a section of a fragment of the walls of the can, to better illustrate the construction.

In said drawing, A represents a long sheet of what may preferably be ordinary turpentine log pulp paper. This strip of paper in width is the height of the intended can or vessel, and in length is several times the circumference of the intended can. In the instance shown, and in better practice, the strip should be long enough to wind four or five .or more times around a mandrel equal in diameter to the interior of the intended can. One face of this sheet of pulp paper is coated with hot asphaltunrB, or any suitalole cement which may be fused by heat, and which, when it becomes cold, will be hard. Upon one end of this strip is superposed a sheet of hard finished, sulfite, spruce pulp C, equal in width to the strip A, but in length extending only a suficient distance to equal or slightly exceed the inner circumference of the intended can. This sheet C is made to adhere to the sheet A by means of the asphaltum. The combined sheet A-C, after the asphaltum has become set and cold is wound upon a mandrel into the form shown at Fig. 1, heat being simultaneously applied to cause the wound sheet to adhere to itself by reason of the coating of fusilole cement.

Application filed September 20, 1912. Serial No. 721,359.

tions is a composite can wall having an inner surface of hard finished sulfite, spruce pulp, suitable to come into contact with fresh, sweet-milk, without imparting any taste thereto, and sufficiently insoluble so as not to be materially affected by contact with the milk. Outside of this coating the wall consists of a series of concentric layers of ordinary, wood pulp paper, securely bound and held together by an intercalated coating of a fusible cement. It has been discovered that when such a wall is formed of layers of paper held together by a fusible cement, as contradistinguished from an ordinary paste or cement held in solution by some solvent, that the walls so composed of layers of paper and the fusible cement will be perfectly impervious not only to moisture, but also to'gases and aromas and greases. The cement, holding no solvent, does not require to dry out, that is to say, does not require to have the solvent pass out through the cemented layers, which passage tends to produce porosity. Secured to the cylindrical wall, as shown in Fig. 1, are the sheet metal bottom D and the sheet metal top E, the latter being provided with an opening F, similar to the opening formed in a milk bottle, and to receive the paper closing disk G which may be sprung into place as similar disks are put into milk bottles. lhe paper lining H on the inner face of the sheet metal bottom and top may be applied and joined with the sheet metal parts to the walls.

The sheet metal can top and can bottom are secured to the walls with a usual form of joint, as will be seen by reference to Fig. 1. Such a joint may be made entirely tight and proof against leakage of gas, moisture or grease of any made in the manner above described costs very much less than an ordinary milk bottle of the same capacity, and also much less than an ordinary sheet metal can of similar capacity, and yet it is of such constitution that even when tightly closed, milk may be kind. The can or vessel processed or sterilized by heating, as well erable distances, a supplemental sheet metal cover J may be soldered over the opening can, by reason of the nature of its walls. Where it is desired to ship the milk considin the head, and said cover being furnished with a key tag 9' may be easily removed or torn ofl by rolling on a key, after the fa miliar way of opening sardine cans, for example.

The can, with its walls made in the manner described, can be used for packing such articles as shrimp, which require to be processed, and which contain a natural acid or chemical constituent, which acts upon the sheet metal surfaces. In such use, of course, the sheet metal surfaces of this can need to be coated with paper,'as indicated, and in such case the top of the can would be made the same as the bottom is shown to be.

In 'using this vessel for the delivery of milk, the milk may be placed in the vessel, the stopper G inserted and the milk may then, if desired, be subjected to a sterilizing heat of 175 degrees Fahrenheit or upward, without materially affecting the walls of the can. The milk may then be sent out and delivered. Or, if it is not desired to sterilize the milk, the filled vessels being suitably chilled, may be sent out to the consumer the same as milk bottles are now commonly sent out, with this difference, that the'walls of this vessel are a much better non-conductor of heat than either glass or metal, and consequently the milk contained will keep its preliminary chill longer and be less affected by heat; and with this still further difl'er- 'ence, that the package is so cheap as comunder the action of the heat and pressure on the mandrel, flow out under this overlapping'part and cause it to adhere firmly to the adjacent surface.

, I claim 1. A vessel comprising the following elements: a sheet of paper having applied to arness one surface thereof a cement, and at one end of said sheet a short sheet of hard finished sulfite pulp between which and the paper cement is contained, such composite sheet being wound into convolutions of which the hard finished sulfite pulp sheet is the innermost and forms the inner surface of the vessel, cement on the face of the paper sheet being united with the back of said sheet, thereby forming a hollow body; the said body having crimped to its edges a sheet metal bottom, and a sheet metal top having an opening therein.

2. A vessel comprising walls made of convolutions of a sheet ofpaper united by both the face and the back of the sheet, and having sheet metal heads crimped to said walls, the top head being formed with an interiorly flanged opening the flange of which is formed With'a concave rounded peripheral groove in which is seated a flexible removable closing disk, and a supplemental sheet metal cover J secured on the plane exterior surface of the top head over the said disk.

3. A containing vessel comprising walls made of layers of paper cemented together, and having sheet metal heads crimped to said walls, one of said heads having a shouldered flange abutted against the inner face of said wall and having a head flange extending inwardly from said shoulder flange and formed with an opening, the edge of said opening being formed with a depending flange having an inner peripheral recess, and a removable closing disk seated in said peripheral recess.

i. A containing vessel comprising walls made of layers of paper cemented together, and having sheet metal heads crimped to said walls, one of said heads havinga shouldered flange abutted against the inner face of said wall and having a head flange ex tending inwardly from said shoulder flange and formed with an opening, the edge of said opening being formed with a depending flange having an inner peripheral recess,

a removable closing disk seated in said peripheral recess, and a supplemental sheet metal cover soldered to said head flange and adapted to be ripped therefrom.
