My invention relates to box containers of the carton type which are adapted both for the packing and effective display of their contents.

Boxes of this type are customarily made up from cardboard blanks, which are scored, out, and folded so as first to form in an integral structure both the top and body of a box suitable for the shipment of its intended contents and which is adapted, by the novel manner in which the body and top can be reassembled and interlocked, to set the box in position for attractive display of itscontents on a counter, show case, or shop window.

Boxes of this general character have had a favorable reception by boththe trade and the public. The particular problem to be solved in their construction is to devise a simple and inexpensive means for interlocking the box body with the top so as to set the body firmly in the desired inclined display position.

According to my present invention, the top of the box is connected by a flap to one end of the body bottom and when the box is set up in display position such body edge rests upon the inverted top and is supported in tilted position by a flap on its under forward edge which folds inside of the end wall of the inverted top and props the body in inclined position with its under end preferably braced between the end and side walls of the top.

My invention further comprises the provision of means to interlock the under forward end of the box when in display position with the end wall of the top.

My invention further contemplates providing the flap, that connects the box body and top, with means adapted to interlock it with the side walls of the top when the box is set up in display position.

My invention further contemplates the provision of a standard box design in which, with the depth of the box half of its length, it can be folded and interlocked in display position without the provision of extra scoring in either the top or the flap, but in adapting my invention to different shapes, additional scoring may be provided either in the top or in the flap in position to permit of the fold required to properly set the body in its display position in its inverted top.

It is characteristic of all forms of my invention in display position that the flap and top form a double thickness interlocked rearward extension that afiords an elongated and very sturdy support for the box body in its tilted position and this I accomplish without waste of stock and with a minimum amount of labor or inconvenience in setting up the box for shipment or display.

My invention further comprises the novel details of construction and arrangements of parts which are hereinafter more particularly described in several embodiments, reference being had to the accompanying drawings which form a part of this specification, and in which:

Fig. 1 shows a blank cut for what I term a standard box having a depth half of its length and embodying my present invention.

Fig. 2 is a side elevation of the box and top with their respectivefiaps set up and interlocked in operative position.

Fig. 3 shows in side elevation the box closed for shipping service.

Fig. 4 is a similar view of the box set up in display position.

Fig. 5 is a front view enlarged of Fig. 4 showing the advertising flap in display position and the end wall of the box top broken away to show the lock lip at the forward edge of the under end of the body.

Fig. 6 is an enlarged cross-sectional view taken on the line VIVI of Fig. 5, showing the manner in which the body lock lip interlocks with the end wall of the top when the box rests upon its supporting flap in display position.

Fig. 7 is a fragmental view corresponding to Fig. 6 showing the box parts about to be forced into interlocked display position.

Figs. 8, 9 and 12 correspond to Figs. 1, 2 and 7 and show a simplified box design omitting the display flap, and the flaps provided at the top edges of the box body sides and adding a second body lock lip to engage the end wall of the top.

Figs. 10 and 11 are enlarged views in side elevation showing how the box body is sprung down and interlocked with the top to provide a stiff reinforced support for the tilted body.-

Fig. 13 shows a blank for a box having a depth less than half its length, thus necessitating an additionalscore line for the display fold, formed in the top opposite which the sides of the top terminate.

Figs. 14 and 15 are plan and side views respectively of the closed box developed from the blank in Fig, 13.

Fig. 16 is a view corresponding to Fig. 13, except that here the box depth is greater than half of its length and therefore the additional display fold score line has to be formed in the flap.

Figs. 17 and 18 are respectively plan and side views of a box developed from the blank in Fig. 16.

Similar reference numerals refer to similar parts throughout the drawings.

In the embodiment of my invention illustrated in Figs. 1 to '7, I show a box and top formed from a unitary blank, the body comprising the bottom 20, duplicate side walls 2|, each having a top inwardly foldable flap 22. The sides 2| carry at their left hand end the end wall flaps 23 and at their right hand end the end wall flaps 24 and 25. Between the flaps 23 lies an end extension coextensive in width with the bottom and formed with cross scores that define the flaps 26, 2-1 and 23. The flaps 26 and 21 are substantially equal in size to each other and to the flaps 23, and the end flap 2B is a lock flap adapted to be engaged under the lock lip 29 in the adjacent end of the body bottom 20. In the flap I cut out a display panel 3!] adapted to fold outwardly along th score line 3| so as to occupy the display position shown more clearly in Figs. 4 and 5. During shipment the flap 30 is left in position in the flap 26.

The right hand end of the body bottom 20 carries an elongated extension coequal in Width with the bottom except that it is slightly enlarged along its side edges to form the side lock lips 32 which are cut out of the end flaps 24 and 25 beyond which it is provided with side flaps 33 that are gradually enlarged toward the free end of the extension where they are joined to the end flaps 34 for the top.

This extension is scored to define the top proper 35, flanked on each'side by the tapering side flaps 33 and connected by a flap 33 to the bottom 2|) and at its outerend carrying an end flap scored to define an outside end wallmember 31, an inside end wall member 38 and an end lock flap 39 that is adapted to be engaged under the lock lip 40, cut in the adjacent end of the top 35. Suitable score lines define the connected pairs of flaps 33 and 34. The flaps 24 and 25 are cut away near their outer ends to permit the top side flaps 33 to extend to the inner end of the top 35, but this is only the preferable construction as the flaps 33 may terminate short of the inner end of the top 35, if such be desired.

The flap 24 has a lock slit 43 cut therein and the flap 25 is cut to provide a lock flap 4| adapted to interlock in the slit 4!]. Also the flap 25 has a score line 42 defining the prop fiap 43. At or near the center of this score line 42 I make a cut into the flap 43 which will define a lock lip 44. In the end flap member 38 I form a cut 45 for forming a lock slot. The flaps 34 ar out out at 46 so that when they are folded across and overlapped in the end wall of the top these slots will register with the cut 45 and form a deep aperture to receive the lock lip 44 in the manner hereinafter described.

Having cut and scored the blank as described, my improved box is set up as follows. The flaps 23, 2| and 25, and 23, 2| and 24 are folded up to vertical position; the flaps 23 are then folded into overlapped relation across the end of the 7 box body; the flap 25 is brought up on the outside of the lapped flaps 23 and then flap 21 is folded down on the inside of said lapped flaps and interlocked in this position by catching its lock flap 28 under the bottom lock lip 29; the other end flaps 24 and 25 are then folded together and interlocked by engaging flap 4| in slit 40; the end flaps 33, 34 on each side of the top are then folded up to vertical position; flaps 34 are thenfolded across into lapped relation; flap 3'! is folded up on the outside of said lapped flaps; and then flap 38 is folded down on the inside of said lapped flaps and its flap 39 is caught under the lock lip 40 to hold the end wall ssembled. The box is now set up as it is shown in Fig. 2 and is ready to be packed. After it is packed the side flaps 22 and the end support flap 43 are folded in, the flap 36 is folded up against the end of the box body and the top is folded down and engaged over the body to close it, as shown in Fig. 3. To set the box in display position, its top is folded down in inverted position shown in Fig. 2, and the body is then lifted, causing the flap 36 to pivot about the adjacent end of the top 35 until it is folded down upon the top, as indicated in Fig. 4. The forward edge of the lower body end wall carrying the and lock lip 44 and the prop flap 43, has this flap bent down at right angles to the position shown in Fig. '7, thus leaving the lock lip 44 projecting freely beyond the edge of the body end wall. If now the body be forced downwardly from the position shown in Fig. 'l to that shown in Fig. 6, its end lock lip 44 will press the fiap 41, defined by the cut 45, in so that the lock lip will be free to engage in the aperture formed by the lock slot in the wall flap 38 and the slots 43 in the flaps 34.

Fig. 6 shows the lock lip 44 pressed against the flap 41 and engaged not only under the flap 38 but also under both flaps 34 and the prop flap 43 resting upon the lock flap 39 in position between the lock lip 45 and the flap 38. When the parts are in this position it will be seen from Fig. 6 that the flap 36 has been sprung downwardly past dead center until it engages the top 35 at which time the forward edge of the box will be pressed firmly into locked relation with the end wall of the top and will be seated between side walls 33 of the top. In order to further lock the parts in this assembled display position, I form slots 43 in each flap 33 along its junction with the top 35 in such position that the side lock lips 32 on the flap 38 will swing down into register with these slots 48 and can be engaged therein to lock the body supporting elements 33 and 36 more rigidly together.

With the box thus set up in position to exhibit its contents, its flap 30 is free to be bent up to display position shown in Figs. 4 and 5 and will carry any suitable advertising and descriptive matter.

The embodiment of my invention illustrated in Figs. 8 to 12 is similar to that already described and the corresponding parts in both forms bear the same identifying numeral and are differentiated as follows:-- The flap 26a distinguishes from 26 in that it omits the display flap 30; the flaps 2|a differ from 2| in that they do not bear the top flaps 22. The flap 24a distinguishes from 24 in that it is provided with a second end lock lip 53, set opposite to and adapted to match with the lock lip 44 on the fiap 25 to provide a double lock lip, to interlock in the aperture formed by the cut 45, instead of a single lock lip as shown in Fig. 1.

Figs, 10 and 11 apply equally to the box design in Figs. 1 and 8 and illustrate a little more clearly how the box is sprung to its display position in order to lock the lips 32 in the slots 48 in the top sides 33. This form of box is assembled exactly as described for the box shown in Fig. 1 with the exception that the two overlapping lock lips 45 and 53 will be engaged in the lock aperture formed by thecut 45 in the top end wall element 38.

In the embodiment of my invention illustrated in Figs. 13 to 15, the elements similar to those shown in the blanks of Figs. 1 and 8 are correspondingly numbered and therefore their description need not be repeated. The particular style of box illustrated in Fig. 13 is one in which the flap 351), as defined by the normal top score line is less than one-half the length of the top 352) This calls for the following changes, namelyz-The flaps 24b and 2517 are made somewhat narrower than the flaps Z ta and 25 because the box is of a longer and shallower type; the lock lips 32 in this design are shifted up to the right hand end of the narrow flap 36b adjacent to the score line 5!: a display fold score line 52 provided across the top which is so spaced from the right hand end of the top 351) that when the fold for display set up is made on this line 52 the box will set up as shown in Fig. 11. The top is not bent on the score line 52 but on the score line 5| when the box is set up for shipment as shown in Fig. 15 where it will appear that the sides 33b terminate short of the right end of the body and for this reason the flaps 22b are used so as to make sure of an overlap between the top and the side walls 2ib across the gap left between the fiaps 33b and the flaps 35b.

The slots EB are placed so that the score line 52 lies an equal distance between them and the lock lips 32, thereby insuring that the lips will interlock with the slots. It will be obvious, however, that if desired the lock lips 32 may be shown in the same position as in Fig. 8, in which event the slots 48 would be correspondingly displaced to the right so that they and the lock lips will be always equidistant from the display fold score line 52.

The type of box shown in Figs. 16 to 18 has the same depth as, but is materially shorter and wider than, that shown in Fig, 2. This calls for a relative shortening of the flaps 230 as compared with the flaps 23 of Fig. 1; the widening of all of the transverse panels of the Fig. 1 blank, with the wider panels bearing the same numerals as in Fig. l but distinguished by the coefficient c. The normal score line 53 is at the end of the top 350 which folds upon this line to assume its closed position shown in Fig. 18, but in order for the box to be folded into display position, it is necessary to place its extra score line 54 down in the panel 360, because the distance from 54 across the flap 360 to the bottom We added to the depth of the box will approximate the distance from the score line 54 to the right hand end of the top 350. Thus, to set this box in display position it is necessary to fold the panel 360 along the line 54 which will bring the lock lips 44 and 5B in position to interlock in the cut 45 in the end wall of the top. In this view the side lock lips 32 are placed as in Fig. 1 and the slots 48 are equi-distant with these lips from the score line 5%.

It Will be obvious therefore that my present invention is flexible in its application to boxes differing in shape and conformation, all, however, being characterized by the fact that the flap connecting the body and top when folded about the display score line down upon the inverted top will permit the adjacent end wall of the body to be interlocked at an upward inclinationwith the end wall, and between the side walls, of the top and'to be so supported by a prop flap 43 when it is bent down and in engagement with the underlying top, thus giving a sturdy elongated support to the box standing on end and tilted to display position.

One important feature of my invention is that the side lips 32 so interlock the body to the top that the box when set in display position can be lifted about to place it without the top falling away from the body and thus the parts are positively held assembled in their display position.

While I have shown'my invention in several forms, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various other changes and modifications, without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are imposed by the prior art or as are specifically set forth in the appended claims.
