Referring now to the drawings in which the various parts are indicated by numerals, box 11, as shown in FIGS. 5, 6 and 7, is formed from a somewhat rectangular flat blank 13 of paperboardor similar sheet material. Blank 13 includes basically four

sections

15, 17, 19 and 21, as best seen in FIG. 1. Longitudinally and transversely extending fold lines demarcate various portions of blank 13. A first substantially continuous fold line 25 and a second fold line 27 extend respectively substantially the length of blank 13. Transversely extending

fold lines

29, 31 and 33 extend respectively between

fold lines

25, 27 and define

sections

15, 17, 19 and 21 of the blank. Each of the four sections includes side, bottom, and top portions which form, respectively, the side, bottom and top panel elements of the box.

Side portions

35, 37, 39 and 41 of the respective blank sections are demarcated by

fold lines

25, 27 and by transversely extending

fold lines

29, 31 and 33.

Bottom portions

43, 45, 47 and 49 extend outwardly from first fold line 25 and ICC respectively from

side portions

35, 37, 39 and 41.

Top portions

51, 53, 55 and 57 extend outwardly from second fold line 27 and respectively from

side portions

35, 37, 39 and 41. Box 11 is shown as being cube-shaped with a square base and a height equal to the base length of a side; however, the design of the box is such that the height may be varied to correspond to the height of the item to be packaged.

bottom partition portions

59, 61, 63 and 65, and

bottom portions

43, 47 include respectively bottom

partition extension portions

67, 69.

Fold lines

71, 73, and 77 and fold lines 79 and 81 demarcate the various portions of

bottom portions

43, 45, 47 and 49. It will be noted that the distances respectively between

fold lines

71, 73, 75 and 77 and first fold line 25 are equal and that this distance is one-half the distance of the base length of a side of the box, that is, one-half the width of a side of the box.

The top partition portions respectively of

sections

15, 17, 19 and 21 respectively include

top partition portions

83, 85, 87 and 89.

Fold lines

91, 93 and 95 integrally secure respectively

top partition portions

83, 85 and 87 to the main body of

top portions

51, 53, 55. Top partition portion 89 is secured to handle portion 96 which, in turn, is secured to top portion 57.

Handle portion 96 includes alike and U-shaped half portions including an inner half portion 97 and an outer half portion 99.

Half portions

97, 99 are secured along a medianly disposed fold line 101 with the respective leg portions extending oppositely. Inner half portion 97 is integrally secured along

respective fold lines

103 and 103 at the respective base of each leg to top portion 57. Top partition portion 89 is joined at the respective base of each leg of outer half portion 99 of handle portion 96. Oppositely extending

ear portions

107, 107 are included in top partition portion 89.

Recesses

109, 109 are disposed respectively in

top partition portions

85, 89. Recesses 109, 109' are medianly disposed and extend transversely inward from the marginal edges respectively of

top partition portions

85, 89.

Slots

111, 111 extend transversely and substantially bisect respectively

top partition portions

51, 55. Slots 111, 111' respectively intersect

fold lines

91, 95 and extend substantially half the width of respective top partition por

tions

83, 87. Slots 111, 111' preferably terminate respectively at the inward ends thereof a short distance from second fold line 27. Obliquely extending slits 113, 113' extend respectively between the inward ends of slots 111, 111' and second fold line 27. Two outwardly extending

tab portions

115, 115 are integrally secured to top portion 53 of section 17 of the blank. A flap 117 is secured to side portion 35 along a fold line 119 extending substantially between first fold line 25 and second fold line 27.

Four adhesive bindings preferably secure the erected box; two bindings 121 respectively are in the lower area St the box for securing the bottom partition portions of the blank; a binding 123 is provided for laminatingly securing the handle; and a binding 125 is provided for joining the opposite ends of blank 13 and for joining flap 117 of section 15 to the edge of side portion 41 of section 21.

In erecting the box, the necessary folds are made along the respective fold lines. The various panels joined by a respective fold line are all subsequently in right-angular relationship in the erected box except for handle

half portions

97, 99 which are in parallel abutting relationship.

The folds are all made along the respective fold lines of the blank toward the subsequent inside of the box.

Handle 96 is formed by double-folding handle

half portions

97, 99 and securing these portions with glue or other such adhesive material. The two bindings 121 in the lower portion of the folded box blank are formed respectively by laminatingly securing bottom partition extension 67 of section 15 with bottom partition 61 of section 17, as by glue or the like, and by laminatingly securing partition extension 69 of section 19 with partition portion 65 of section 21, as by glue or the like.

In erecting the box,

side portions

35, 37 are rightangularly folded along fold line 29, and

side portions

39, 41 are right-angularly folded along fold line 33. The box in this stage of erection is substantially in two parts, joined along fold line 31 and including a first part of sections 15 and 17 and a second part of

sections

19 and 21. To complete the erection of the box, the two parts are interlocked at the bottom portions thereof, and

side portions

35, 41 are right-angularly joined by binding 125. Binding flap 117 is right-angularly formed along fold line 119 and is laminatingly secured along the inside surface of said portion 41.

In the erected box, four upstanding partitioning panels are formed in the lower area of the box, as best seen in FIG. 3. The four partitioning panels include respectively a pair of oppositely disposed single-thickness partitioning panels and a pair of oppositely disposed double-thickness partitioning panels. The pair of single-thickness panels are formed respectively from

bottom partition portions

59 and 63. The double-thickness partitioning panels are formed respectively by laminatingly joining bottom partition extension portion 67 to bottom partition portion 61 and by joining bottom partition extension 69 and bottom partition portion 65.

It may be desirable in certain applications to delete the

bottom extension portions

67, 69 from the box blank, or to eliminate bindings 125. It may also be desirable to employ contact or pressure type adhesive means to the respective surfaces to be joined, so that the box may be readily erected at the place of use. It may also be desirable in certain applications to fasten the respective parts at

bindings

121, 123 and 125 with wire staples or the like. It may further be desirable to eliminate binding flap 117 and substitute therefor binding tape for joining

side portions

35 and 41.

In packing or closing the erected box, the four cylindrical items are placed in the four square partitioned-off areas (FIG. 3). The

top portions

51, 55 of sections 15, 19 are folded over the items, forming an inner pair of top closure panels (FIG. 6). The

top portions

53, 57 of

sections

17, 21 are then folded over the inner pair of closure panels, forming an outer pair of closure panels (FIG. 7) and completing the closure of the box.

Referring to FIG. 6, it will be noted that slots 111, 111' respectively of the inner pair of top closure panels align to form a continuous slot. It will further be noted that the top partition portions respectively of the pair of top portions are abuttingly parallel and depend downwardly between the items contained in the box. The

top partition portions

85, 89 of the outer pair of closure panels are in parallel abutting relationship and extending through the continuous slot formed by

slots

111, 111.

Recesses

109, 109 of the

top partition portions

85, 89 straddle respectively

portions

127, 127 of

extension portions

83, 87 of the inner pair of top portions. The

partition portions

83, 87 and 85, 89 of the closed box form double-thickness right-angular X-shaped partitioning means for separating the items contained. In closing the box, the oppositely disposed

ear portions

107, 107 are urged respectively through the obliquely extending

slits

113, 113. Urging ear portions 107, 107'

past slots

111, 111 securely closes or locks the box. As the outer pair of closure panels are folded inwardly together, tab portions 115, 115' are inserted underneath the respective oppositely disposed corner edge portions of top portion 57, and as the box is locked by

ear portions

107, 107, the tab portions 115, 115' provide additional means for securely closing the box.

Although the present invention has been described and illustrated with reference to a preferred embodiment, it is to be understood that it is not to be so limited since changes and modifications may be made therein which are within the full intended scope of this invention as hereinafter claimed.
