Application April 2, 1942, Serial No. 431,347 1 claims. (Cl. 229-31) This invention relates to folding cardboard boxes and is an improvement over the folding box set forth in my U. S. Letters Patent No. 2,274,- 714 granted March 3, 1942.
In my prior patent above referred to, the folding box is constructed from a single blank of cardboard which is cut, scored, and foldable to assume a flat collapsed position during non-use. and by an easy and rapid manipulation, the box may be set up for use. When in set up position, the box is held against accidental collapsing by naps folded inwardly from two opposed outer walls of double wall structure. However. in the invention about to be described, the opposed locking flaps are foldable inwardly from the inner walls of opposed double wall structures, which enables inwardly foldable top flaps, cover flaps, or cover rest flaps to be formed integral with the opposed outer walls.
Other features of the invention will become apparent as the specification is read in conjunction with the accompanying drawings. in which,
Figure 1 is a plan view of the cardboard blank from which the box is constructed.

Figure 10 is an enlarged detail vertical sectional view on the line l0l0 of Figure 9.
Figure 11 is a perspective view of a further modification of the invention.
Referring to the drawings by reference characters, and at present to Figure 1, the letter A designates a substantially rectangular shaped blank of foldable cardboard which is scored on suitably spaced longitudinal score lines I0 and H inwardly of the longitudinal edges of the blank and parallel thereto. The blank is further provided with suitably spaced tra sverse scores "-42 inwardly from the ends of the blank. The aforementioned score lines divide the main portion of the blank A into a rectangular shaped bottom wall IS, an intermediate side wall forming panel B, and a narrow glue flap l4. The bottom wall i3 is bounded by one longitudinal side edge of the blank, score 10 and scores |2l2. The intermediate side wall forming panel B is bounded by the scores II), II, and l2l2. The glue flap I4 is bounded by the score H and adjacent free edge of the blank with its ends terminating free adjacent the scores l2l2.
The blank A is further scored on the transverse scores 5-15 which are parallel to the scores l2l2 and disposed outwardly thereof. The distance between the scores l2 and adjacent scores 15 predetermines the height of the end wall structure of the box. By reason of the scores l5|5, the blank is further formed with inner end walls 16-" and outer end walls lT--|'I. The inner end walls l6l6 are bounded by the scores IO, H, II, and IS. The outer end walls ll-ll are bounded by the scores l0, l2, l5 and the adjacent edge of the blank. Glue flaps Iii-i8 are connected to the inner end walls Iii-l6 along the score H and are adjacent the ends of the glue flap l4- and free of the same.
The side wall forming panel B is divided by a medial slit [9 into two like side walls 20-40, the ends of the slit terminating beyond the mid-portlon of the inner end walls Iii-I6. The inner ends of the slit I9 are connected by diagonal scores 2| provided in the inner end walls It and which extend to the corners defined by the intersection of the scores l0-l2 and lI-i2. The diagonal scores provide triangular corner folds or webs 22 which fold flat against the walls Iii-l6 when the blank is folded to box forming position.
Formed integral with the inner end walls I6-i6 and connected thereto along the hinge scores 15-45 are inwardly foldable end wall locking flaps 23-23 of a height and width substantially the same as the inner end walls lB-l6 to which they are respectively connected. Relatively narrow bottom wall engaging flaps 24-24 are connected to the flaps 23--23 along hinge scores 25-45. Connected to the outer end walls l (-41 along the hinge scores I5 are inwardly foldable top flaps 26, the outer sides of which may contain printed matter as well as the side and outer end walls.
l0, after which the glue sides of the flaps l4 and lO-ll are folded inwardly over the bottom wall l3 and outer end walls ll-ll respectively. The box is now in flat collapsed position (Fig. 2) for compact packing, shipping, and storage, and may, 5
by a subsequent simple manual manipulation, be further folded to set up position for use. To set up the box from its collapsed position shown in Figure 2, an operator grasps the two ends in the region of the inner end walls |5-| 5 and pulls l0 upwardly thereon to cause the outer end walls ll-l I. to pivot on the scores |2-|2, during which time the triangular webs 22-22 fold on the diagonal scores 2|-2|, and the side walls 20-20 swing upwardly to a position substantially perpendicular to the bottom wall i3. The operator may now fold the locking flaps 23-23 inwardly within the box on the scores |5-| 5 to a position to lie flat against the folded webs 22-22 at which time the end edges of the flaps 23-23 are in tight frictional contact with the side walls 20-20. Due to outside scoring of the scores i0 and II, the side walls 20-20 have a tendency to open up and with the end edges of the flaps 23-23 engaging the side walls 20-20 at their corners with the triangular webs 22-22, the box is secured against unfolding. The flaps 24-24 are now folded inwardly on the scores 25-25 to lie flat against the bottom wall is and brace the bottom and side walls at their ends. The box is now in set up position, but after articles are packaged therein, such as tomatoes, apples, or the like, the top display flaps 25-25 are folded inwardly on the scores |5-| 5. The entire box may now be wrapped in Cellophane and sealed, so that the contents of the box are readily visible for inspection.
In Figure 6 of the drawings, I have illustrated my invention embodied in a folding box in which a cover 25a takes place of one of the top flaps 25. The other top flap 25 is omitted to expose the space or pocket P defined by an outer end wall I! and adjacent spaced apart wall I5. The cover 25a is of a length and width to cover the open top of the box and its free end is provided with a downturned flap 2! for insertion into the pocket P when the cover is in closed position. The cover may also be provided with downturned side flaps 25 for closing the joint between the sides of the cover and the top edges of the side walls 20-20.
In Figure 7 there is illustrated a further adaptation of the invention, wherein the outer end walls have inturned top flaps 25b formed integral therewith along the hinge score |5 to provide cover rests for a cover 29. The cover 29 is integral with the top edge of one of the side walls 20 along a hinge score 30 and has a front flap 3| insertible into the box against the other wall 20 when the cover is closed. When closed, the free side edges of the cover 29 rest upon the inturned rest flaps 25b.
In Figures 8 to 10, inclusive, I have illustrated a modified form of my invention wherein it is embodied in a folding box construction somewhat similar to that set forth in Ringler Patent No. 2,220,121 granted November 5, 1940. The folding box shown in set up position in Figure 9 is formed from the cardboard blank C illustrated in Figure 8. The blank C is substantially rectangular and comprises a bottom wall 40, outer end walls 4|-4| hingedly connected to the bottom wall 40 along the transverse score lines 42-42 and side walls 43-43 hingedly connected to the bottom wall 40 along the longitudinal score lines 44-44. The side walls 43 and end walls 4| are connected by folding corner webs, each of which comprises a triangular shaped web section 45 hinged to one end of the side wall 43 along the score line 45 and a triangular shaped. web section 4'! hinged to the adjacent end of the outer end wall 4| along the score line 40. The web sections 45 and 41 are hingedly connected along the diagonal score lines 45 which extend from the corners of the bottom wall to the free side edges of the blank.
Connected to the web sections 41 along hinge scores are inner end wall sections 5| having flaps 52 connected thereto along hinge scores 52. The sections 5| along one longitudinal side of the blank are provided with extension portions 54 to receive a dab of glue 55 from a glue roller when the blank is passed through an automatic folding and gluing machine. When the pairs of section 5| at the ends of the blank are folded inwardly, they overlap and are secured together by th glue 55 to provide a single inner end wall. The blank is initially folded on the score lines 44 and 48, with the glue sides of the extension portions facing and engaging the other section 5| of that pair. When the blank C is folded and glued in the manner just described it is in collapsed condition for subsequent hand folding to set up position in a manner to be presently explained.
Connected to the outer end walls 4| along hinge scores 55 are inwardly foldable top flaps 51 similar to the flaps 25 and serving the same purpose.
To set up the box from the initial folded and glued position, the operator grasps the glued together inner end wall sections 5| and pulls upwardly thereon to cause the outer end walls 4| to swing upward on the hinge scores 42, th side walls 43 being simultaneously pulled upwardly by hinging on the score lines 44. As the walls 4| and 43 move to upstanding position, the web sections 45 fold upon and against their companion web sections 50, the latter flatly fitting against the inner side of the adjacent outer end walls 4|. The operator now folds the lapped glued together inner end walls 5| inwardly within the box body to a, position flat against the folded corner web sections 45, which causes the sections 53 to strike the bottom wall 40 and flatly fold thereagainst by hinging on the score line 53. The end edges of the sections 5| frictionally engage the inner sides of the side walls 43, whereby the box is held in set up position for use. After the box has been filled, the top flaps 51 are folded inwardly to a horizontal position on the hinge scores 55, and the box with its contents is wrapped in a sheet of transparent Cellophane to confine the contents and to expose the same to view for inspection.
Whereas the inner end wall sections or flaps 5| are less than the width of the box, one of said sections 5| may be equal to the full width of the box and the other narrow glue flap if desired. In such construction the seam between the glue sections 5| would be adjacent the comer of a side wall and not visible when the box is in erected position.
In Figure 11 of the drawings, I have illustrated a further modified form which is similar to the box body shown in Figure 6, except that the top flaps 25 are left off both ends to provide pockets P-P to receive th free end walls or tongues 50-50 of a separate removable telescoping cover 5|.
The pockets P ma also be used to receive leaflets containing printed matter pertaining to the merchandise packed in the box. Also, a price tag may be inserted into the pocket when the box containing merchandise is placed on display.
From the foregoing description it will be understood that in all adaptations of the invention, the box is provided with folding end wall structures wherein inner and outer walls are provided. the outer walls having integral inwardly folding top flaps which may be used for display purposes, for a cover, or for cover supporting flaps. Whereas several adaptations of the invention have been disclosed herein, it is to be understood that other modifications of the invention may be resorted to as come within the scope of the appended claims.
