4 claims.

'I'his invention -relates to containers and,

i' among other objects, aims to provide an improved container which may be used'satisfactorily to replace the metal cans in which icef cream is packed for the retail trade, the particular object beingl to provide a paper can of ample strength which maybe nested", for economy in shipping and in storage space, yet may be tightly closed at the top by a flanged cover` or l cap and will haveian unusually strong and leakproof bottom construction.

This applicationis a companion to application Serial No. 600,797 led March 23, 1932.

NkFig. 5 is a horizontal sectional view taken on line 5--5 of Fig. 3 but drawn on the scale of Fig. 1:

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

Fig. 7 is a horizontal sectional view taken on the line 'I-l of Fig. 2, but drawn on the scale of Fig. 1; and V y Fig. 8 is a fragmentary view of the blank from which the cover flange is made.

Paper containers are in use for holding small Iquantities of ice-cream and other foodstuffs but so far as I know, there are no satisfactory paper cans, capable of holding one to ten gallons of ice-cream or other semi-solids, which can with--l stand the usage which such containers receive in shipping, trucking and refrigerating. The present invention provides an improved paper can which meets all of the requirements of the icecream 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 drawings, there is shown a paper can III having a,l truste-conical body portion II of slight taper, the large end o being at the top of the container, so that the empty containers may 4be nested. The body is conveniently formed by wrapping a sheet of heavy, treated paper board around a tapered mandrel land securing the overlapping edges together by suitable stitches I2. These stitches may be applied by a traveling stitching head (not shown), while the blank is held on thev mandrel.

In order that a cap or cover I3 may be fric-y tionally secured on the container and atthe same time to provide a ange by which the container 5 may be gripped for ,lifting andcarrying,j the upo per portion of the frusto-conical container is built out so as to be cylindrical. Herein, a. collar I4 of heavy, stiff paper, having its lower portion bent inwardly and upwardly, as at I5, is secured to the upper portion of the body II on the outside by glue or the like. The upper edge of the collar I4 contacts with the body I I while the lower portion is spaced a suiiicient amount from the body by the inwardly and upwardly bent portion I5, so that the outer surface of the collar I4 is substantially cylindrical. An outer collar member I6, also of heavy paper, is secured as by glue outside of the collar I4, and its lower edge provides a flange under which a can lifter may be engaged, the width of the collar I6 being such that it conveniently accommodates can lifters at present in use, so that the can may be lifted out of a refrigerating compartment or truck body.

The width of the inner collar I4 exceeds that of the collar I 6, so that its lower edgel is below the natural nesting point of the can; thus, when the cans are nested, the ange I'I formed by the lower edge of the collar I4 engages the top of the next lower can Illa (indicated in dotted lines in Fig. 2) to prevent the cans from being wedged together, which would make the nested contain ers diflicult to separate. The double thickness collar provides a strong reinforcement for the container at the top edge, as well as a friction surfacefor the cap I3, to be described. l

" The blank from which the container is made, a

portion of which is shown in Fig. 6, is providedV at its lower end with a series of integral tongues 40 I8, shaped somewhat like gear teeth, the purpose of which is to interlock the side wall of the can with the bottom. The lower end of the blank is adapted to be bent on the dotted lines I9.F 2|! and 2| to form akind of bead (Fig. 3) for 45 strengthening the bottom of the can. The blank is bent'inwardly on line 2| and then upwardly on line 20 to forman inner wall 22, which',y is spaced from the outer wall, as shown in Fig. 3,

and the tongues I8 are then bent inwardly 4on 50.

line I 9 forming a circular, inwardly extending flange. To further strengthen the bead at the lower end of the container, a relatively thick. ring 23 of heavy paper board is secured between the inner and outer walls by glue. 55

liliA The bottom of the container is made 'of at least two disks of fiber board 2l and 25, the disk 24 being above the flange formed by the tongues I8 and glued thereto. The other disk 25 is glued at its marginal portion to the undersides of the tongues I8 and at its central portion to the undersldeof disk 24, as will be clear from Fig. 3. The diameter of the disk 24 is such that it can be inserted as far as its final position only by a press fit, without buckling however, and thus very tightly engages the inner wall of the container. The edge of the disk 25 is-likewise secured by a press fit against the inner wall 22. The tongues I8 present ample surface for the glue to form a strong joint, and are so shaped that the tongues for another blank are provided by the material between them, thus effecting a saving of material when cutting out the blanks. Another advantage of the tongues is that there, are no points to become bent in handling.

The cover I3 may be formed in a manner similar to the bottom of the container, exce'pt that no bead is necessary. The blank from which the flange of the cover is made (a portion of which is shown in Fig. 8) comprises an elongated strip of material having integral tongues 26 similar to tongues I8. The flange blank is bent into cylindrical form, the ends being overlapped and secured together, forming a ilange 21, the inner diameter of which is substantially the same as the outside diameter of the collar I6, so as to be frictionally secured thereto. The tongues 26 are bent inwardly on line 28 to provide an inner circumferential flange. A disk 29, preferably of corrugated board, is glued to the underside of the flange so formed and a disk 30 of paper is glued to the outerside of the flange and to the disk 29. This construction provides a reinforcedcap which is sufficiently strong to protect the top ofthe container and its contents from damage. The container and its cover are treated on their interior surfaces, so as to be moisture-proof, preferably in accordance with the disclosure of application Ser. No. 586,630, filed January 14, 1932 and assigned to the assignee of this application, thus making the containers particularly adapted for use with ice-cream, butter, lard or other similar materials.

The reinforcing collars at the top and bottom of the container and the glued disks and ringJ of tongues at the bottom together with the bead result in a strong and durable container which will withstand much abuse. At the same time,

the container is soinexpensive that it may be discarded after being once used, and in this respect it effects considerable savings in handling,

forcing collar secured to the upper portion of the container, said collar having its lower end bent inwardly and extending upwardly to space the lower end of the collar from the frusto-conical side wall; the outside wall of said collar being cylindrical.

2. A nesting container comprising, in ycombination, a frusto-conical body made from a single sheet of flexible paper board whose edges are overlapped and secured together; a reinforcing collar secured to the upper portion of the container, said collar having its lower end bent inwardly and upwardly to space the lower end of the collar from the frusto-conical side wall; the outside of said collar being cylindrical; and a second cylindrical collar secured to the first cylindrical collar on the outside and having its lower edge above the lower edge of the first collar.

3. A nesting container comprising a frustoconical body of treated paper; a collar consisting of a paper ring secured on the outside of said body at the upper end, said paper ring having its lower edge doubled under, so as to cause the outer face of the ring to stand out from the frusto-conical, body, and thus provide a cylindrical outer faceadapted to frictionally hold a flanged cover; the lower edge of said collar being below the natural nesting point of the container, to obviate the jamming of two nested containers.

4. A nesting container comprising a frustoconical body of treated paper; a collar consisting of a paper ring secured on the outside of said body at the upper end, said paper ring having its lower edge doubled under, so as to cause the outer face of the ring to stand out from the frusto-conical body, and thus provide a cylindrical outer face; the lower edge of said collar being below the natural nesting point of the container, to obviate the jamming of two nested containers; and another cylindrical collar surrounding and secured to the first but of less width, and so positioned that its lower edge is spaced above the lower, doubled edge of the first collar.
