other-objects, aims to provide an improved reinforced container which may be used satisfactorily in lieu of the metal cans in which ice cream is packed for the retail trade, the particular object being to provide a paper can which may be nested, for economy in shipping and in storage space, yet may be tightly closed'at the top by a flanged cover or cap and will have an unusually .10 strong and leak-resisting bottom construction.

- This is a companion application to application Ser. No. 600,798, filed March 23, 1932.

In the drawing, showing a preferred embodiment of the-invention:

Fig. 1 is a side'elevation of the improved container;

Fig. 2 is a horizontal sectional view taken on line 2--2 of Fig. 1;

Fig. 3 is an enlarged, vertical, fragmentary, 20 sectional view of the upper part of the container;

Fig. 4 is an, enlarged, vertical, fragmentary, sectional view of the lower part of the container;

Fig. 5 is a'horizontal sectional view, taken on line 5-5 of Fig. 4; and

Fig. 6 is a fragmentary view of the lower portion of .the blank from which the container is made.

Various kinds of paper containers are in use for holding small quantities of ice cream and 30 other foodstuffs but so far as I knowythere are no satisfactory paper cans capable of holding one to ten gallons of ice cream or other semisolids which can withstand the usage which such containers receive in shipping, trucking and re- 35 frigerating. The present invention provides an improved large paper can which meets all of the requirements of the trade and which may also be nested so as to require a minimum of space during shipment or when stored empty.

Referring particularly to the drawing, there is shown a paper can having a frusto-conical body portion H] of slight taper, the larger end being 7 at the top of the container, so that the empty containers may be nested. The body is conven- 45 iently formed by wrapping a sheet of fiber board around a tapered mandrel and securing the overlapping edges together by suitable stitches,l|.

In order that a cap or cover (not shown) may be frictionally secured on the container, and at 50 the same time to provide a shoulder for engagement by lifting devices, the upper portion 12 of the body is made cylindrical, as shown in Fig. 3,

and a collar I3 is secured on the cylindrical portion. This collar is preferably made by winding 55 two layers of fiber board spirally in opposite diproofmaterial so that the containers are particuv 2 Claims. 91: 229-55) This invention relates to containers and, among I rections on a forming mandrel. The spiral winding is so accomplished as to provide abutting but not overlapping edges, as shown in Fig. 1, to insure a nearly true cylindrical outer surface. The

I collar is preferably secured on the container by 6 glue or the like. As the outer surface of the col- .lar is cylindrical, this permits a flanged cap (not shown) to be frictionally held on the container, which would not be possible if the container were tapered at the top. Also, the collar materially 10 strengthens the container. The lower edge of the outside layer ll of the collar provides a shoulder under which a can lifter (not shown)' may be engaged, the width of the outside layer being such that it conveniently accommodates 16 present day can lifters, so that the can may be lifted out of a refrigerating compartment or truck body. The width of the inner layer l5 may be the same as the outer layer l4 but is preferably greater so as to provide additional 20 reinforcement. At the same time, it is not so wide as to become wedged in the next lower container when nested, which would make the nested containers diflicult to separate.

The blank from which the container is made, a portion of which is shown in Fig. 6, is provided at its lower end with a series of integral tongues l6 each tapering to a point. The lower end of the blank is adapted to be bent on the dotted lines I! and I8 to form a kind of a bead for strengthening the bottom of the can. That portion of the blank between lines ll and I8 is bent inwardly and upwardly on line l8 to fonn an inner wall l9, which is spaced from the outer wall, as shown in Fig. 4, and the tongues are then bent inwardly on line I! forming an inner circumferential flange. To further strengthen the container, an annular collar .20. formed of several layers of spirally wound paper material is secured between the inner and outer walls by glue. The bottom of the container is made of at least two disks of fiber board 2| and 22, the disk 2| above the flange formed by the tongues 16 and glued thereto. The other disk 22 is glued at its marginal portion to the undersides of the tongues i6 and at its central portion to the underside of disk 2|, as will be clear from Fig. 4. The diameters of the disks are such that the disk 2i can only be inserted. as far as its final position by a press fit and thus very tightly engages the inner wall of the container, While the edge of disk 22 is likewise pressed against the inner wall IS. The entire container is prefei ably coated on the inside with paraiiin or other suitable moisture Wm mm m m m mm m.
