BRICK-ICE-CREAM BOX.

Application filed January 7, 1922. Serial No. 527,729.

5 State of New York, have invented certain new and useful Improvements in and Relating to Brick-Ice-Cream Boxes, of which the following is a specit.-.;ation.

This invention relates to certain improve- 1o ments in paper material boxes of the flat blank type; and the objects and nature of the invention will be readily understood by those skilled in the art in the light of the following explanations of the accompanying l5 drawings illustrating what I now believe to be the preferred mechanical expression or embodiment of my invention from among other forms, constructions and arrangements within the spirit and'scope thereof.

It is an object of my invention to produce a rectangular box of such construction and formation as to be peculiarly adapted to be filled through one end with semi-frozen flowable ice cream by means of an ice cream container filling machine, particularly of the type that embodies a nozzle through which the ice cream flows and on which the box can be moved longitudinally to fill the box from the. bottom us as it inoves downwardly on the nozzle; and to produce said peculiar box of such formation that the semifrozen cream can be hardened therein, so that the box of hardened cream can thereafter be delivered to the untimate consumer 5 and constitute an original package.

With these and other objects in view my invention consists in certain novel features in construction and in combinations, formations and arrangements as more fully and particularly set forth and specified hereinafter.

Referring to the accompanying drawings: Fig. '1 is a reduced-scale plan view of the flat paper material blank that is utilized to (a form the particular embodiment illustrated so Fig. 5 is a perspective View of the set up box, the top closure being shown elevated from the box body, the bottom closing flaps being shown swungdown from closing adjustment, and an inner bottom disk being shown separated from the box.

Fig. 6 is a longitudinal se tion of the box, dotted lines showing one of the inner lining flaps of the box in a position it assumes when being inserted in the box during the operation of setting up the box.

Fig. 7 is a cross section of the set up box.

Fig. 8 is a plan View of the box folded flat for paraflining or other water proofing and for packing for shipment.

Fig. 9 is a perspective view of the box set up for filling.

The container or box in set up or operative form for filling, is rectangular in cross section and longitudinally elongated or oblong in shape, or in other words, approximately of the form of a common block or brick of ice cream. In this set up form, the box consists of a tubular body composed of a sheet of paper or like material having its ends overlapping and secured together by adhesive to form a permanent tight seam (see 1 throughout the length of the box body. Said sheet of paper is bent on parallel longitudinal scored or other suitable fold lines I) to provide panels 1, 3, forming the box sidewalls, and panels 2, 4, forming the box edge walls, with the fold lines 12 forming the longitudinal corners of the box. The sheet is formed with any suitable means, such as the common flaps 1", 2", 4", integral with the sheet and adapted to bend up in a well known manner, to provide the bottom closure of the box, while the upper end of the box body is open and unobstructed, for filling. After the box has been filled any suitable top cover or closure can be applied thereto. For instance, an outside paper ma terial flanged slip cover 6, can be employed (Figs. 2, 5), or a paper disk 7 having an upstanding flange and forming an internal slip cover, (Fig. 3), or a flat paper material closure or cover disk 8 (Fig. 4), or an internal paper material flanged slip cover 9 (Fig. 6). To provide the box with the required internally and externally unobstructed mouth or open end without free or projecting edges that might catch on filling ma chine parts and to render the box stiff and of the required stability as well as of the required tightness against cream leakage and undue exposure to air, the box body is a formed with internal walls or layers, or an internal facing or lining as an integral part thereof. In the partidular embodiment illustrated, each exterior wall panel 1, 2, 3,

4, is, in the setup box, covered throughout its inner side surface, by a layer or internal wall, formed by free end interior longitudinal panels or flaps 1 2 3, 4, depending from the upper ends of said exterior wall panels, respectively, and extending throughout the interior length of the box body. These interior longitudinal flaps abut at their free longitudinal edge portions at the longitudinal internal corners of and throughout the length of the box, and henceform, and constitute the ice-cream contacting longitudinal internal surfaces of the box. These interior longitudinal flaps form integral parts of the sheet forming the box body and form downward continuations of the upper ends of the exterior wall panels along the doubled continuous folded edge that constitutes the annular more or less rounded top edge 0 surrounding the open end of the box; The junction between the exterior wall,

panels and the interior flaps is established by the fold line a.

If so desired, a flat paper disk 10 can be inserted in the open top of the set up box and pressed down onto thebottom thereof to form the internal ice-cream-contactin bottom floor of the box. This disk 10 wi closely conform to the internal cross sectional dimensions of the box and will rest on whichever bottom closure flap 2 or 4 that happens to ,be uppermost and at its edges will engage the inner surfaces of the four interior longitudinal flaps, and thus will fit between the free ends of said flaps and press and hold the ame outwardly to position. This disk not only internally seals the lower end of the box against approximate air and cream leakage, but'also serves as a follower or head against which pressure can be applied in forcing thebrick of ice cream from the open end of the box, for serving, when the cover has been removed and the bottom closure flaps have been opened or cut off. However, I do not wish to limit all features of my invention to the employment of the disk 10, as said disk is not an essential part of my box for all purposes.

The particular embodiment of my inyention disclosed by the drawings is (with theexception of the top cover and inside bottom disk 10) composed of a single sheet of paper or like more orless stiff yet foldable material, first cut to form a fiat blank of the approximate form and configuration disclosed by Fig. 1. By the use of approi priate machinery, these blanks can be rapidly and economically produced, and can be packed in small space for storage or shipment. The boxes, h wever, are produced in neraeee hock-down fiat form, for packing and shipment in suc flat form, to the icecream manufacturer or other user. The boxes are thus produced in fiat form, by folding the blank on the several foldlines b, so that the opposite ends of the blank will overlap, the

in opposite directions from the opposite edges thereof. This box blank is collapsed to flat form along two fold lines b with a side panel and an edge panel, say 1' and 2, resting on and parallel with the opposite side and edge panels, say 3 and 4, and with the straight flat flaps 1 2 resting on and.

parallel with the flaps 3, 4 and with the straight flap 1 resting on the flap 4.

These knock-down flat boxes can be packed in small compass for shipment and storage. The collapsed flattened box can be easily set up for filling, by expanding the box body to rectangular tubular form; then folding the bottom closure inner flaps 2 4" inwardly into parallelism traversing the open lower end of the box body and resting one on the other; then folding the exterior locking flap 1 inwardly into parallelism with said inner flaps and bending up its locking tongue 1 and inserting the same upwardly into the box past the edges of the inner flaps; and then successively, one after the other, bending down the flaps 1 2 3, 49, into the box through the open upper end thereof and straightening the same out with in the box and pressing the same outwardl against the outer wall panels of thebox. f

'an inner bottom disk 10 is to be employed,

x. Of course, in setting up the box, the long internal flaps can be inserted and properly positioned within the box body, if so desired, before the bottom closure flaps are folded to operative bottom forming position.

It will be noted, that the long internal flaps are approximately coincident in length with the box body and with the outer wall panels 1 etc. so as to completely face the inner longitudinal surfaces of said panels.

The box is thus provided with double walls,

and is exceedingly stable, strong durable to withstand the expansion of the cream during the hardening process, as well as handling after hardening and before the box of hardened cream reaches the ultimate consumer. The double wall formation also reduces to the minimum deterioration of longitudinally onto and from the nozzle.-

The nozzle entering the box presses the longitudinal internal flaps out against the outer wall panels and the semi-fluid cream that fills the box from the bottom up main tains the flaps in such position. The formation of the box mouth is such that it can properly cooperate with the tapered mouth of the guiding head which holds the same to form during the filling operation and centers the same with respect to the nozzle and forms a tight joint therewith. The box formation is also such as to render the box capable of use in other filling machines and devices, and for other purposes than for ice cream.

The ultimate consumer can readily separate the box from the hard brick of ice cream therein in various ways, as by pushing the brick from the box as hereinbefore described, or by tearing the box and separating the paper pieces from the ice cream by a knife blade, or by removing the end closures and slitting the box along one corner by a knife and then spreading the box and separating the inner flaps from the block by a knife blade,'as said flaps may adhere thereto even though the inner surfaces of the flaps are parafiined or otherwise waterproofed.

The-collapsed flattened out boxes which have been glued at the scams or joints 1, can be readily waterproofed or parafined by running the same through sets of paraffining rollers. This process will waterproof the outer surfaces of the outer wall panels 1, 2, etc., and also what are then the outer surfaces of the longitudinal inner wall flaps l 2, etc. and both inner and outer surfaces of one bottom closure flap 2*, or 4", and the outer surfaces of closure flap 1 and the other flap 2" or 4". Thus when the collapsed box is set up in operative form, the paraifined surfaces of the inner wall flaps 1 2, etc. will form the ice-cream-contacting'. surfaces of the box side walls and the outer. surfaces of the exterior walls will also be water-proofed. This constitutes an advantage whereby economy in waterproofing is gained by reason of the peculiar box blank formation.

While I have in Figs. 5 and 6, shown the follower or forcing disk 10, located at the bottom of the box and while said disk 10 performs certain sealing functions when so located without regard to its possible use as a follower for ice cream block discharging purposes, yet the follower disk for discharging purposes can be located at either end of the block of ice cream. The disk 10 can be located in the bottom of the box, and another disk. such as 8, Fig. 4, can be located on top of the block of ice cream to serve as a pusher or follower to force the block of cream from the bottom of the box when the bottom flaps are opened or cut off. Also. covers, such as 7 (Fig. 3) or 9 (Fig. 6) can be used as forcing followers. Also, where disk 8 (Fig. l) is to be used as a forcing follower. an outside exterior slip cover. such as 6 (Fig. 2) can also be employed.

It is evident that various changes, modifications and variations might be resorted to without departing from the spirit and scope of my invention and hence I do not wish to limit my invention to the exact disclosures hereof.
