,I Application October 23, 1936, Serial No. 107,120 y 'l Claims.

This invention relates to paper containers and a closure therefor. The invention is particularly useful in containers of relatively large size adapt- 'ed for storage and shipment of bulk goods, and

Y especially where the goods are to be dispensed from the containers. It is to be understood that the term -paper is intended tocover lpaper or the like fibrous sheet materials or other suitable sheetl materials readily adapting themselves to the type of construction hereinrdisclosed.

The class of ldevice to which the invention is particularly adapted i'lnds a wide use as a means for packing andshipping ice cream andm other frozen edibles; the ice cream customarily being placedin the containers in fluid condition and the containers then'being stacked-in a freezing room and from there shipped to dealers. One popular size for such containers is 21/2 gallons. Preferably, where the size is 21/2 gallons or smaller, the dealers stack two or more containers one upon the other in refrigerating cabinets and dispense the ice cream froml the containers as the demand arises. It has been found thatin containers of this class, the closure heretofore employed become displacedin handling the lled containers for storage vand shipment purposes, 'and that' in stacking the' lled containers in storage, shipment and dispensing use the superposed containers were not as stable as desired. Furthermore, when in .dispensing use, as in a dealers refrigerating cabinet, With the containers open for access with aserving dipper, the prior devices did not permit secure stacking.

Anobject of this invention is to provide an article possessing the advantages and free from Ithe objections heretofore lreferredto; and at the same time providing an article which' mightbe economically and commercially manufactured.

This invention consists in the novel features, arrangements and combination of parts 'embodied byway of example in the article hereinafter described as' illustrating the preferred form of the invention, and the invention will' belmore 'particularly pointedl out in the appended claims.'

Further objects, features and advantages of the invention4 will appear from the followingspecification and claims taken in connection with the accompanyingdrawing, in which v Fig. 1 is avperspective view of a container and closure therefor,

Fig. 2 is a segmental longitudinal section showing in further particularity Vthe structural de-v tails.

3 is a somewhat similar view showing the i 55 relationship of a series ofcontainers when inV i iency so stacked condition while the containers remain unopened, and i Fig. 4; is a similar View illustrating the relationship.` vas in Fig. 3, but with the containers opened.

The container is formed with a lmulti-ply spirally wound cylindrical side wall l, in the. lower.endv of which is suitably supported the bottom 2. .The upper edge of the body l is turned over to provide a bead 3 which is preferably in the nature of a relatively lobse rolled section and whichV preferably provides a .certain degree of resiliency in the bead. While the invention contemplates container bodies of various forms, it is more especially applicable where the bodies are in collapsible form. Y

The closure means comprises a side wall element 4 and a cover element 5. 'Ihe sidewall 4 (Fig. 2) is in the 'form of a cylindrical band which may be made inany suitable manner but which is shown as being formed'of multi-ply spirally wound paper stock, whose upper edge is turned inwardly to provide a bead S which is preferably in the form of a rolled edge and whose lower edge is turned inwardly to provide a bead 1 preferably in the' form of a relatively loose rolled edge. The said beads '6 and 1 are spaced apart in an axial direction a distance substantially equal to the thickness of the cover member 5 plus the vertical thickness of the bead 3 so as to provide a substantially tight seal between cover 5 andbeadll, as is clearly indicated in Fig. 2; and the cover member 5, which preferably is in thewform of a disc of heavy cardboard or other suitable material, is held within the side wall 4 byand between the beads 6 and 1. 'Thel lower bead 1 provides a certain degree of resilthat although its internal diameter isy v"substantially less than the external diameter Iof the bead 3, nevertheless there is sufficient resiliency in the aggregate between the beads 3 and 1 to permit the bead 1 to be snapped over the bead 3, andwhen this has been done the disposition and formation of the parts aresuch that the disclis held between the beads 6 and` 3 by means of the locking action of the bead 1 beneath the bead 3. The internal diameter of the member 4A intermediatethe beads 6 and 1 is substantially equalto the external diameter of the bead 3,' and-the internal diameters of the vbeads 6 and 1 are substantially equal to the external diamv eter of the container body l; these dimensions being such thatthe band 4 snugly engages the bead 3 and the bead 1snugly1engages the'exsenor ofthe container may 4|, 1n adamant@ being positioned underneath the bead 3 as previously described. v

, The construction of the container closure and the relationship of the disc cover 5 and band 4 provide certain additional advantages. For example, with the disc freely disposed between the beads 6 and 1 the closure means may be inserted in the reverse direction to that shown in Fig. 2, whereby the bead 6 will be positioned beneath the -bead 3 and the bead 1 .will be positioned above the bead 3 with the disc 5 held between the beads l and 3 instead of ,between '6 and 3 as illustrated in Fig. 2; thus permitting disc 5 to be put in with either face upwardly and hence permitting a reversal to disclose a differ ent type of face or a face having different characteristics as indicia, instructions, etc. In either of the positions of the closure means in assembled relationship with the container it is to be particularly noted that in stacking the containers one upon the other when the closure means vare in position there is provided means for holding the stacked containers in cooperative relationship as will be clearly illustrated by referring `to Fig. 3, from which it will be seen that the uppermost bead (in the illustration the bead 6) is adapted for intertting engagement so as to receive the lower end of a superimposed container. In this condition the stacked containers are very securely and rmly heldin the desired relationship.

It is particularly within the contemplation of the invention that when the containers are in use, such as in dispensing ice cream or other contentstherefrom, the cover member or disc 5 be removed without disturbing the band 4, thereby leaving the band 4 with its two marginal beads B and 'l in position as a protection for the upper edge of the container when invdispensing use, such for example as when scoops are used to remove ice cream therefrom; and in this condition the opened containers may yet be stacked one upon the other, such as in the dealers refrigerating cabinet, as will be clearly illustrated in Fig. 4. This is particularly desirable because containers of this character may be used in multiple-(as where several flavors of ice' cream are packed in respectively separate containers) within a single cell or hole of a dealers refrigerating unit and remain in stacked but open condition, so that ready access may be had to any given container with relatively little trouble. A

It will be understood from the foregoing that where the inventive embodiment comprises a'container wall l which is collapsible (such for example as that disclosed in our previous Patent No. 2,037,675), the cover band being reinforced as it is by the beads such as (i and?, serves to ma-' terially reinforce the collapsible side wall l and hold it in substantially cylindrical condition at its upper end even after the cover 5 has been re- V moved and regardless ofthe degree kto which the contents have been removed.

Having thus described our invention with particularity with reference to its preferred vform, it will be obvious to those skilled in the art, after understanding our invention, that other changes and modifications may be made therein without departing from the spirit and. scope of our invention, and we aim in the appended claims to cover such changes and modic'ations as are within the scope of the invention.
