Slain/as.

invention relates to certain improvements in boxes ci the type specified, the parts of which may be stamped from a sheet of cardboard or suitable stiff paper and scored at the places where the parts are to be bent, and shipped to the user ilat in relatively small boxes, crates or packages, and which may be readily put together by the consignee or packer, as needed without the employment of glue, nails or any other fastening devices.

A further object o1" this invention is to provide a box or a container oi the character specied, the parts of which are easily assembled in proper relationship to torni a box and when so assembled, provide a relatively rigid structure, the parts 0i which are not easily separated, even though the box may be handled when empty, and in which, with the placement therein oi confectionery and the like, the separate parts are the more nrrnly secured together by the weight of the contents of the box.

A further object of this invention is to provide a box or container of the character referred to which may be provided with a rectangular cover of any ordinary construction which nts fiat against at least four sides of the box and which may provide a plurality of triangular spaces between the cover and the vertical walls oi the box proper at the corners ci the cover thereby providing a package having an appearance distinctive and diiierent from those ordinarily employed and which, when adopted by a inanuiacturer for the packing ci his goods therein, may substantially a distinctive and individual appearance as to identify the goods as oi a known ori in. The manufacturer may thus distinguish his goods from the goods of his cornpetitors.

A further obje-ct of this invention is to provide box, inade or" sheet material in the form of a blank or blanks ci suitable shape and suitably scored, consisting ci a bottom and side walls, the bottoni being in shape preferably polygonal (all four or incre sides being not necessarily of the same length), and the side wall being composed of a scored and iolded strip of sheet material the lower edge ci which fits around the edges of the bottom, to which the bottom is securely fastened by ineens of tabs and tongues, with which the bottoni is provided, the tongues being insertable into being retained within slots in the adjacent side Walls, the side wall comprising a double thickness of sheet material, the plies lying substantially flat against each other with the tongues or tabs of the bottom 1ying iiat between the double side wall or walls and concealed from view by the outer wall.

A further object of this invention is to provide a box having the characteristics last above described and in which the inner plies of the vertical wall abut against the upper surface of the bottoni to prevent any accidental detachnient or removal of the tongues from the slots in which the tongues have been inserted.

Other objects 0i the invention will appear in Si? the specication and claims below.

Referring to the drawings forming a part of this specication, and in which the saine reference characters are employed throughout the various views to designate the same parts, 7G

Fig. l is a plan View of two separate blanks with the desired cuts and scoring ready to be bent along the scored lines and formed into a box in accordance with my invention;

Fig. 2 is a perspective view of the two blanks 'Z5 illustrated in Fig. 1 and showing a box in the process of assembly, three of the vertical walls being in the final position in which they are in the Jfinished box, and the other sections of the strip forming the vertical wall being in their natural position just prior to the step of bringing the fourth and fifth sections of the vertical wall of the box into the position for securing the fth section to the said bottom;

Fig. 3 is a perspective view similar t0 Fig. 2 85 but showing the completed assembled box or container;

Fig. 4 is a top plan view of the finished box with a square or rectangular cover enclosing the same, a part of the top or the cover being broken 3o away to show the box fitting therein;

Fig. 5 is a Vertical, sectional view on the line 5 5 of Fig. a, but on a substantially larger scale;

Fig. 6 is aV section on the line 6 6 of Fig. 4 but on the larger scale employed in Fig. 5;

Fig. 7 shows in plan view a blank which is a slight modification of that shown in Fig. 1 in that the bottom and the side walls are integral, the bottom and sides being cut out of a sheet of suitable material as a single blank. Except for obvious dierences in detail, the blanks are substantially identical.

Fig. 8 is a fragmentary view of one of the flaps provided with a slot oiiset in the saine way as shown in the previous modiiications but in which the cuts at the end are at right angles to the direction of the slot to form a small iiap; and

Fig. 9 is a View or" a bottom tab with its tongue adapted to cooperate with the flap shown in the preceding ligure.

fic

Fig. 10 is another fragmentary View oi a further modification in which the slot and' flap, like that shown in Fig. 8, is arranged symmetrically with respect to the median line of the flap; and

Fig. 11 shows a tab with a slightly modied tongue adapted to cooperate with said tab of Fig. 10.

Referring iirst to the preferred form of the invention as illustrated in Figs. 1 to 6 inclusive, the bottom 1 of the bottom blank 2 is shown as a symmetrical figure having eight straight side edges from each oi which outwardly extend substantially rectangular tabs 3 from the longer sides or edges and the tabs 4 from the shorter sides or edges respectively. Scorings 5 are provided between the tabs 3 and 4 and the bottom l, these scorings 5 form the boundaries of the bottom oi the completed box. The larger tabs 3 are preferably provided with substantially semicircula-r or semielliptical tongues 6 cut through the material, the base of the tongue being integrally connected to the tab 3 but provided with a scoring 7 on which the tongue may be bent slightly out of the plane of the tab as will be referred to again below. In this embodiment of my invention, I also form in the base line or scoring 7, a short cut to form a locking slot 6 which will also be again referred to below.

The blank 8 from which the side wall of the box is made also comprises a single integral strip of sheet material provided with transverse scorings 9 spaced from each other distances respectively equal to the lengths of the straight boundaries of the bottom i, so that the scorings 9 will lie against the apices of the angles around the bottom 1 of the box and to provide as many straight rectangular panels 10 and 1l as there are straight edges around the bottom 1 of the box.

In Fig. 1, the larger panels 10 correspond to the longer edges of the bottom and the smaller panels 11 to the shorter edges of the bottom. The blank V6 is substantially in width twice the height of the finished box. It is provided with a longitudinal scoring 12 substantially midway between the longitudinal sides of the blank and in alinement with the transverse scorings 9, the blank is provided with slowly tapering cuts 13 from the longitudinal scoring 12 to the edge of the blank, thus forming substantially rectangular wide tabs 14 connected to the wide panels 10 and narrower substantially rectangular tabs 15 connected to the smaller panels 11, these tabs being integrally connected to the corresponding panels at the longitudinal scoring 12 or top edge of the iinished wall. The wider or larger tabs 14 are provided with cuts or slots 16 extending parallel to the longitudinal scoring 12 preferably spaced from the outer free edge of the tab substantially the same distance that the scoring 7 of the tongues 6 of the bottom is spaced from its adjacent scoring 5, and the cut 16 is of substantially the length of the width of the tongues 6 at the lines of scorings '7. These cuts 16, however, are not symmetrically disposed with respect to the axes or vertical median lines of the panels 10, and of the tabs 14, but are oiiset slightly to the right thereof (in the example shown in Fig. l) for a purpose to be more fully disclosed below. The ends of the cuts 16 which are nearest the edges of the adjacent tabs 14 is provided with a short angular cut 17 extending toward the longitudinal scoring 12. The lefthand end panel 10 of Fig.. 1 is provided with an arcuate cut or slot 18 and next adjacent and beyond the right-hand smaller panel 11, the blank is provided with a locking tab 19 which is provided with a rounded end 20 which, in conjunction with a transverse slot, 21, forms a hook or head adapted for insertion into the slot 18 when the box is assembled, the said end 20 being retained within the slot 18 by the engagement of the bottom 21 of the slot 21 with the end 18 of the slot 18 as will more fully appear below.

While the longitudinal scoring l2 is substantially midway between the sides of the blank 8, it is, in fact, slightly offset toward the free edges of the tabs 14 and 15 so that the height of the tabs 14 and 15 will be slightly less than the height of the panels l0 and l1. This is to compensate for the thickness of the material which forms the bottom 1 so that the bottom side of the bottom or base 1 of the assembled box will be substantially in the plane of the free edges of the panels 10, and 11 and the free edges of the tabs 15 will be in the plane of and press against the top surface of the bottom i in the assembled box.

It is here in order to refer to the relation between the tongues 6, the cuts 6' and the slots 16. The tongues, it will be observed, are preferably symmetrically arranged with respect to the tabs 3 in which they are respectively cut, but in order that the bottoni of the slots 6', when inserted into the slots 16 may bear rmly against the ends 16 of the slots 16, the slots 16, which are of substantially the width of the tongues 6, are offset to one side of the median or axial line of the wider tabs 14, a distance substantially equal to the length or depth of the slots 6. The reason for this will now appear as the manner of assembling the bottom and the side walls is now described, L

attention being particularly directed to Fig. 2.

The tabs 3 and 4 or" the bottom blank 2 are first bent along the scoring lines 5 to extend substantially vertically upwardly, to lie in planes substantially at right angles to the bottom 1.

rI'he side wall blank 8 is next folded longitudinally along the longitudinal scoring line 12. rI'hus, from the position shown in Fig. 1, the tabs 14 and 15 are bent upwardly around the scoring line 12 and are then pressed down to lie fiat against the correspondincr panels l0 and l1. Having been so folded, the tongue 6 in one of the tabs 3 is flexed outwardly from the planes of the tab and away from the center of the bottom 1 vand is inserted then into the slot 16 at the end of the folded side wall blank 3. After the tongue has thus been inserted into the slot 16, it and its tab 3 are drawn or slid longitudinally to the left (or the iiap 14 is drawn to the right) to position the end 16' of the slot 16 at the bottom of the slot 6 of the tongue 6. In this position, the tongue 6 will be symmetrically positioned with respect to the ap 14 into slot 16 of which the tongue 6 has thus been inserted and it cannot be moved straight upwardly therefrom to remove the tongue from the said slot.

The adjacent narrower or smaller tab 4 is now heldin a plane at right angles to the plane of the bottom 1 of the box and the adjacent narrow ilap 15 of the wall is bent down over it so that the tab 4 lies between a narrower panel 11 and the corresponding narrow inner iiap 15 of the side wall.

The tongue 6 of the next adjacent large tab 3 is then similarly bent outwardly and inserted into the slot 16 of the next large or wide flap 14 and similarly locked in position. This is the point in the assembly of the box that is shown in Fig. 2. Thereafter the operations above described are repeated with respect to the other tabs, tongues and slots. The next narrow flap 15 of the side wall being laid on the inner side of the corresponding smaller tabs 4 of the bottom, the tongue 6, on the next large tab 3 of the bottom is inserted into the appropriate slot 16 of the now adjacent larger inner flap 14 of the side wall with the tongue 6 locked in the slot 16 and lying between the larger panels 9 of the outer wall and the corresponding inner flap 14 of the vertical wall of the box; and so on until all the tongues 6 have been inserted into the corresponding slots i6. When ail the tongues 6 have thus been inserted in the slots 16 in the manner above described, the end tab 19 will lie over and against the large end panel in which is the arcuate slot 18. The end 20 is then inserted into this slot 18 and when fully inserted, it is pressed downwardly to the boti tom of the end 18 of the slot 18 against the end 21 of slot 2l to the rear of the head 20 of the fastening section 19. The box is now completely assembled with the free ends of the narrow flaps of the side wall frictionally pressing against the the upper surface of the bottom 1, that is to say, these tabs 15 are pressed manually, flat against the smaller tabs 4 of the bottom and when so possitioned they will stay there because of the friction between the ends of the said flaps 15 and the bottom of the box.

This also makes clear why it is preferable to make the height of the narrow tabs 15 slightly less than the height of the panels 10 and 1l, to allow for the thickness of the material which forms the bottom 1 and to cause them to press against the bottom 1 and prevent the bottom from being lifted with respect to the side walls. These flaps 15 are retaining flaps and prevent the separation of the bottom from the sides.

When so assembled and wi en so frictionally retained in place these tabs 15 function to prevent the bottom 1 from being pressed upwardly toward the top edge of the side walls of the box which motion would tend to remove the tongues 6 from their engagement with the slots 16 in the narrow wide tabs 14 of the side wall of the box.

En Fig. 5, the relation of the tongues 6 to the side wall of the box is clearly shown, the tongues lying between an outer panel l0 and the corresponding large inner flap 14 of the side wall, and in Fig. 6, the free end of a flap 15 is shown as in frictional engagement with the upper surface of the bottom 1 of the nnished box to prevent any unintentional removal of the tongues 6 from the slots 16, and to retain the flaps 15 flat against the outer panel l1 with the tab 4 flat between them.

As shown in Fig. 4 this box so assembled is adapted to have fitted thereover, a plain rectangular cover 22 which may be of any suitable construction.

When the cover 22 is placed over the box, as is indicated in Figs. 4, 5 and 6, thc box will ll the cover except at the corners, as shown in Figs. 4 and 6 and the bottom of the closed box will be of a distinctive character and will provide a different appearance from the boxes heretofore employed. The boxes may thus serve to readily identify the goods contained in the box as being of a certain origin or source of manufacture.

The goods for which this novel box has been particularly designed are such that the covers of the lled boxes are usually immediately destroyed by the purchaser (the retailer) and the goods are exposed for sale in the box itself. The square or rectangular cover 22 provides a facile way for packing and shipping a large number of filled boxes and the polygonal shaped box in which the goods are offered for sale presents an unusual and attractive style of package by means of which the customer may immediately recognize the goods as the genuine.

In the modification shown in Fig. 7, the bottom blank 2al and the side wall blank t are integral and are cut from a single piece of sheet material. The bottom 1 is provided with three large tabs 3 and two small tabs 4 like the small tabs 4 of Fig. 1, but two of the smaller tabs 4a are not rectangular in shape but rhomboidal due to the fact that 1 tom 1 in Fig. 7, is the panel in which is located l the arcuate cut or slot 18 for the reception of the head at the opposite end of the side wall piece or strip, and since the blank slip 82L is integral with the bottom member 2a, it is unnecessary to provide the ilap 11ia with a slot 16. In other respects, the two forms of the device are alike. They are folded in the same manner upwardly around the scoring 12 and when so folded upwardly around the scoring 5 surrounding the bottom 1 and when all the tongues 6 have been inserted in the appropriate and corresponding cuts or slots 16 and the fastener 26-21 has been inserted into the slot 18 in the panel 10a the box will have substantially the identical appearance as the box formed up out of the two blanks 2 and 8 of the first modification shown in Fig. 1.

Whilel have thus described with particularity two modifications or embodiments of this invention, the construction may be varied considerably in detail without departing from the spirit and scope of the invention. Thus, while have shown in the two modifications above described the slot 16 with the angular cut 17 at the end thereof, this slot may be formed in a variety of ways. Thus, in Fig. 8, the slot i6 is also shown as oifset with respect to the axial vertical line of the iiap 14, but at the ends of the slot 16 are cuts 17CL at right angles thereto and terminating in a scoring 23, thus forming a small flap 24 which is easily pressed outwardly toward the outer ply of the wall for the insertion of the tongue 6 and after the tongue 6 has been inserted, it is slid sidewise to the center of the panel as indicated by the dotand-dash lines in the upper portion of Fig. 8.V

In this case also the tab 6 is provided with the cut 6 at an end of the scoring '7.

Although, of course, the locking engagement of the cuts 6 with the ends 16 of the slot 16 are `effective to prevent any unintentional eievation of the bottom of the box with respect to the side walls and a withdrawal of the tongues 6 from the slot 16, this short cut 6 may be omitted and the slot 16 may be placed symmetrical with respect to the flap 14, as shown in Fig. 9. In this construction it is the engagement of the free ends of 'i the narrow flaps 15 with the upper surfaces of the bottom 1, which is relied upon to prevent one from sliding the bottom 1 upwardly to disengage the tongues 6 without iirst lifting all the flaps 15.

Nor is-the invention limited to the exact shape of box or to the shape of the blanks from which they are formed, for from my above disclosure, it will be evident, to those skilled in the art of paper box making, that the invention may be embodied in different forms and shapes of boxes with vertical or tapering walls by merely providing properly shaped or formed blanks, it being only necessary to see to it that the blanks for the side walls provide a continuous strip to form the outer wall and coacting flaps, with a crease or scoring between the flaps and the continuous strip so that the flaps may lie flat against the inner side of the outer wall, that the wall be a two-ply wall with the series of naps forming the inner ply, and that the inner flaps be provided with slots into which tongues on the tabs of the bottom are insertable, and that in some cases certain of the inner naps of the wall structure be of such a length that the free ends thereof frictionally engage the upper surface of the bottom when they are pressed flat against the inner surface of the ply forming the outer wall with the tongues between the plies of the side wall.
