The provision of an effective container of such a character presents several difllcult problems, particularly when it is desired that the container be of comparatively light weight, yet have substan-- tial capacity, appropriate for the commercial packaging of materials in bulk, and possess quite substantial strength.

The requirements which such a container must meet in various uses, such, for example, as for the commercial packaging of ice cream or other froaen commodities in bulk, present additional problems. In the case of ice cream packing, for instance, it is a customary practice of ice cream manufacturers to fill the containers, in which the product is distributed to the trade, with the ice cream mixture in a fluid, partly frozen, condition, apply the closure to the container. and then freese the contents in the container. Such freezing is ordinarily done in a freezing room, the containers being stacked one upon another. As an incident of the freezing, the contents of the container expands very considerably in volume. Ordinarily, the containers so used are of fivegallon or two-and-one-half-gallon capacity and, after freezing, the packages are delivered unopened to the trade, and the packages are placed by the dealers in refrigerating cabinets where, after the package is opened, the contents are dispensed or dished out piecemeal from the original container in the making of individual sales. It will be apparent that such usage requires a container which, in addition to being quite tight, must be of very substantial strength and quite accurately sized.

The present invention provides a container which meets these requirements and attains the numerous advantages of a structure which may be supplied to the user in knocked-down condition, set up by him with facility, and which may be supplied at a cost sumciently low to justify its being discarded after being once used.

The nature of the invention will be ascertained most quickly upon an understanding of the illustrative examples shown in the drawings. which will now be described.

The container comprises a body member which is tubular when set up, and suitable end closures. The body member is made of flexible material possessing the requisite toughness and rigidity for the intended use. For an ice cream container of live-gallon capacity, for example, the material may be a suitable paper board approximating .045 inchinthicknem. InFig. 2isrepresentedacross section of such a board, of laminated structure, comprising a chip center portion ll, liner II and craft outer sheet II, all secured together by a suitable adhesive as in customary converting practice. It will be appreciated that the board need not necessarily be of this particular structure, or that it be of laminated structure.

In forming the body member, it is provided along its lower margin with a series of tongues ll, between which the material is slotted, as at I, for a short distance. The body member is formed with flexing creases or slightly oifset portions ll extending in the longitudinal, or top-tobottom, direction and spaced from one another by appropriate intervals. In this creasing or offsetting of the board, the material is not distorted to an extent such as to shear or break the fibers, but the offset is suiiicient to striate the board by forming shallow grooves on one side thereof and low ridges on the other. It will be understood that these creases or oil'sets may be pressed in the board in various fashions and in various forms, and as seen in Fig. 1, their arrangement is such that some of them are staggered or offset laterally relative to the tongues, thereby placing one of them opposite each of the spaces between the tongues. The body member is also creased to provide fold lines l'l on which its opposite portions may be folded into collapsed relationship, as illustrated in Fig. 5. Along the upper margin of the body member, on what is to be the outer side of the container, is secured a strip is which forms an outwardly extending rim. This strip may be creased transvemely in the same fashion as the body member.

The flexing creases or oflset portions Ii facilitate the shaping or conformation of the body member to the desired form or contour when set up, and in order to further this effect, the board may be subjected to a bending operation as illustrated in Fig. 4, by being passed through a flexing machine which bends the board around axes parallel to the creases i. This flexing has the effect of somewhat loosening the flbers at the creased or oii'set portions, without appreciably decreasing the top-to-bottom stiflness of the board, and thus renders it somewhat more flexible at the creased portions. An application of suitable water-prooflng material, such as paraiiin, is made to the surfaces of the board, the same being substantially ironed in so as to avoid any appreciable coating which might be scraped oil. The board is formed into a continuous convention of its meeting or othewise, and is collapsed ben it 0 fold lines II. The body mem b e r is 11 3;110:122: in a collapsed or knocked-down form in which it may be shipped and from which it may be set up in tubular form.

For assembly with the body member, there is provided a relatively non-distensible constraining member 20 of annular form and of slightly greater circumference than the body member. This constraining member has an annular portion ll adapted to extend across the end margin of the body member when it is set up in the desired tubular form, and an inwardly extending portion 2|" which is adapted to encompass the end portion of the tubular body member peripherally. A disk ii of still paper board flts within the constraining member in contact with the portion 20- thereof. Adisk 22 of stiff paper board is also provided, conforming in contour to the desired contour of the body member, but of a diameter somewhat exceeding the contemplated internal diameter thereof. A second relatively non-distensible constraining member 24, of the desired circumferential contour of the body member, is provided for cooperation with the other end of the latter. This second constraining member has an annular portion ll of somewhat greater internal diameter than the contemplated diameter of the set-up body member, and adapted to encompass the upper end portion of the latter peripherally. At the upper end of the portion 2 is an inwardly extending head 24' and at its lower end an inwardly extending flange 24, the flange 24 being of such width that the constraining member may be-slipped into encompassing relationship on the body member, and the bead 24' preferably being body member, as by portions bystaples ll of somewhat greater width so as to extend farther toward the axis of the body member. An end closure disk 25, of stiff paper board, is positioned within the constraining member 24, where its margins are overlapped by the head 24.

In assembling the container from the fiat or knocked-down condition, the collapsed body member is opened to a tubular form. and the tongues I4 are bent inwardly. The tongued end of the body mcmberis then inserted in the constraining member 20, making a close fit with the upper margin of the portion 20", whereby it is constrained in the desired circumferential contour. The inwardly folded tongues rest flat upon the end' disk 2|, and the intervening slots I are of such length that they extend to a point just short of the upper margin of the portion 20 The disk 22 is then inserted edgewise into the body member through its upper end, and, in sloping position, into engagement with a portion of the body member that is within the portion 20 and then pressed down into fiat position against the tongues I4. The disk 22 being oversize, the forcing of it to this position forces the slotted end portion of the body member outwardly under the overhanging or inwardly extending portion 20 of the constraining member, thus locking the body member and the disks 2| and 22 and constraining member 2|! together.

With the body member and container bottom thus assembled, the former is held in its tubular form, and the receptacle thus provided is adapted to stand upright on its bottom, so that it may be readily filled with the material which is to be packaged in it. After the contents are placed in the receptacle, the top closure, comprising the constraining member 24 and disk 25, may be applied to it. The disk 25 being disposed in the constraining member 24, as above described, said disk being of such size as to overlap the top edge of the body member, the constraining member is slipped onto the upper end of the body member so that its .annular band 24 encompasses the upper end of the body member peripherally and the disk 25 seats upon the upper edge of the body member so as to close its top opening. When seated, the inwardly projecting flange 24 will occupy a position below the lower margin of the retaining strip l3, and the bead 24 in its overlapping relationship to the margin of the disk 25, will hold the latter against withdrawal upwardly. Due to the transverse flexibility of the body member, portions of the retaining strip I3 will project over the flange 24 and serve to retain the constraining member and disk 25 against removal readily from the body member.

Assuming that the commodity packed in the container is to be ice cream or some other material which is to be frozen, and which expands on freezing, the closed package may be submitted to freezing treatment, as in a freezing room. With the expansion of the contents resulting from the freezing, outward pressure will be exerted upon the body member, and this will have the effect of distending the latter, as is illustrated in somewhat exaggerated degree in Fig. 7. Such distention is accommodated or facilitated by the pliability of its material and by the character of the creasing, the material in the striae or offset portions I6 being susceptible of displacement radially as the body member is drawn taut in approximately circular peripheral contour. Such distention of the body member is also accommodated, in some measure by its form. As pointed out above, the body member wall is relatively more flexible at the creased portions I6 than in the intervening portions, and as a result, in the setting up of the body member in tubular form, greater flexion may take place at the creases than in the intervening wall portions and the latter may not be fully arched out to a uniform radial distance from theaxis of the container. As a consequence, they .will accommodate an appreciable increase inthe capacity of the container when arched out into approximately circular peripheral contour.

The portions of the body member which are encompassed by the relatively non-distensible parts 20* and 24 of the constraining members are susceptible of distention in the manner above explained, with the result that when so distended by the pressure of the containers contents, they will be pressed into very close binding engagement with said portions of the constraining members. Thus the lower end portion of the body member will be further distended into the recess under the inwardly extending portion 20* of the lower constraining member, the lower end of the body member being susceptible of such distention due to the fact that the tongues I4 are not fixedly secured to the bottom closure, but may slide outwardly between the disks 2| and 22. The portion of the body member encompassed by the upper constraining member 24 may likewise be distended into the internal recess afforded between'the bead 24 and flange 24, so that the latter will grip the body member peripherally and engage definitely below the outwardly extending retaining strip l3. This relationship is illustrated in Fig. 7. The portions of the body member intermediate the two constraining members may be distended appreciably beyond the inner margins of the flanges 24 and 20 The distensible character of the body member thus not only accommodates the expansion of the containers contents, in such fashion that the end closures will not be forced off, but also contributes to a more secure connection of the body member and the end closures.

An alternative form for the constraining member 24 is illustrated in Fig. 8, wherein said member, instead of being provided with an inwardly extending flange at its lower margin, is provided with the inwardly punched burrs 24 which are pressed into the body member peripheral y upon its distention as above described, thus to retain the constraining member securely in place there- A further alternative construction, which may be employed for the bottom constraining member, is illustrated in Fig. 10, wherein the constraining member is designated by the reference character 38 and has an inwardly extending bead 39 at the margin of its body-encompassing portion, adapted to exert binding constriction on the distended body member and to engage and cooperate with a retaining strip 31 which is secured to and projects peripherally from the body member. The constraining member has the inwardly extending annular flange 4| adapted to overlap the marginal portion of the paper board insert disk 40, which disk is preferably of such size as to expand the lower end of the body member somewhat when the disk is forced to normal position therein, and hold it in close engagement with the encompassing constraining member.

As has been indicated above, the constraining members are relatively non-distensible, which characteristic may be attained by forming them as continuous members of strong sheet metal.

' filled and closed containers, one upon another,

In addition to their functioning as constraining members to hold the parts in assembled relationship as above described, they constitute effective enveloping reinforcements for the edges of the container as well as stable elements holding it in shape. Consequently, the fllled container may be rolled along on its lower peripheral edge without crushing or distorting the relatively fragile marginsofthebodymemberorclosurediskaand these margins and the Joints between them are guarded by the enveloping constraining member against wetting and consequent softening when the container is set on a damp floor. It will be observed also that the construction provides a container with substantially flush ends. This feature is of value, not only in guarding the ends of the body member and the end closures against distortion, but also in facilitating the stacking of the and enabling them to withstand the loading pressures resulting from such superimposed weight. It will be apparent that various changes may be made in the particulars or details of construction above described without departing from the spirit and characterizing features of our invention.
