/UTORNEY Oct. 16, 1962 R. K. wlLsoN Two-PIECE Box BoDY Filed July 6, 1959 4 Sheets-Sheet 4 United States Patent O 3,058,643 TWO-PIECE BOX BODY Roy K. Wilson, Jacksonville, Fla., assiguor to St. Regis Paper Company, Jacksonville, Fla., a corporation of New York Filed July 6, 1959, Ser. No. 825,344 2 Claims. (Cl. 229-15) This invention relates to containers and more particularly to a two-piece compartmented box body which is formed from blanks composed of corrugated or solid paper materials such as fiberboard, paperboard, boxboard and the like.

A general object of the invention is to provide an improved box body.

Another object is to provide a two-piece compartmented box body which is durable in construction, easy to assemble from blanks and which is simple in design.

Still another object is to provide a partitioned box body for a container which may be filled With a commodity that tends to settle and thereby take up less space, such as tomatoes, and which is provided with telescoping Walls that are adjustable in height in accord with the level of the commodity in the container.

Another object is to provide a tray arranged to hold together a folded over sleeve of figure-8 shape and Where the sleeve in turn holds the flanges of the tray in position.

The novel features which are believed to be characteristic of this invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and method of operation, together with further advantages thereof, may best be understood by reference to the following description taken in connection with the accompanying drawings, in which:

FIG. l is an exploded perspective view of a box which includes a two-piece box body and a cover therefor;

FIG. 2 is a plan view of a blank from which the cover of the box illustrated in FIG. 1 is formed;

FIG. 3 is a plan view of a blank from which the tray of the box body illustrated in PIG. l is formed;

FIG. 4 is a plain view of a blank from which the outer shell of the box body illustrated in `PIG. 1 is formed;

FG. 5 is a perspective view of the outer shell shown in HG. l, illustrating a form which the shell takes during an intermediate stage of assembly;

PIG. 6 is a perspective view of the assembled box shown in FIG. 1; and

FIG. 7 is a sectional view taken along the line 7-7 of FIG. 6.

The box as shown in FIG. 1 is made up of a cover 1 and a two-piece box body which is generally designated at 2.

The body 2 of the box includes a corner cut flanged tray 3 which functions as a bottom supporting member for commodities carried in the box and an outer shell 4 which telescopes over the upstanding flanges or walls of the tray.

The tray 3 has opposite end wall panels 5 and 6 and opposite side walls 7 and 8. The side walls 7 and 8 are each interrupted by a Vertical slot, as at 13 and 14 which divide the respective side walls into separate panels as at 9 and 10, and at 11 and 12.

The shell 4, on the other hand is composed of a pair of integrally attached open ended

sleeves

15 and 16 which are each provided with opposite end panels as at 17 and 18, and at 19 and 20, and opposite side panels, as at 21 and 22, and at 23 and 24. End panels '18 and 19 function as a double walled partition 28 which divides the shell into two compartments, 25 and 26, that are respectively defined by the

sleeves

15 and 16. The only physical link between the sleeves is along the top edge 27 of the partition 218. When the shell is telescoped over the 3,058,643 Patented Oct. 16, 1962 ICC walls of the tray, the

sleeves

15 and 16 function as bands that support the side and end panels of the tray 3 against outwardly directed forces exerted thereagainst.

It will be noted that

end panels

17 and 20 of the shell 4 are provided with horizontally extending

hand holes

29 and 30 which are spaced below the respective upper edges of the sleeves. The end wall panels 5 and 6 of the tray 3 are provided with internally cut downwardly extending tongues 311 and 32 respectively. The tongues 31 and 32 are so cut from the end panels as to be provided With enlarged lower ends 33 and 34 which are the same size as the

hand holes

30 and 29 respectively and which are arranged to register therewith and pass through the respective hand holes when the shell 4 is fully telescoped over the tray 3. The tongues engage the end panels when the shell is thereafter raised and accordingly provide a means for linking the shell 4 and tray 3 together. The cut which forms the tongue in each case is such, as exemplified by the cut in end panel 6, that the tongue 32 is hinged to the panel 6, as at 35, at a lesser distance from the top edge 36 of the panel than the distance from the bottom edge 37 of the cooperating hand hole 29 to the top edge of end panel 117. This arrangement provides a loose looking attachment between the shell 4 and tray 3 and enables the respective walls thereof to move relatively vertically while still being locked together.

Each of the

end panels

17 and 26 of the shell 4 also have another slot, as at 38 and 39, which is spaced above the adjacent hand hole, therein. As will be shown, these slots 38 and 319 cooperate with tongues in the

end flanges

40 and 41 of the cover 1 and provide a means for securing the cover 1 on the box body 2.

The blank 1' from which the cover is formed is shown in FIG. 2. The blank `1' is generally rectangular in Shape and has longitudnally scored

vlines

42 and 43 along which the top portion 44 of the cover and the side flanges 45 and 46 thereof are integrally attached. Each of the side flanges 45 and 46 has opposite end ap extension, as at 47 and 48, and at 49 and 50', respectively, which are integrally connected along scored lines, as at 50, 51, 52 and 53 to the respective side flanges.

The

end flanges

40 and 41 of the cover are integrally connected to the top portion 44 along transverse scored fold lines 54' and 55', and are separated from the adjacent end flaps 47, 48, 49 and 50' of the side flanges by

end cuts

54, 55, 56 and 57 respectively. Each of the

end flanges

40 and 41 is composed of outer and inner 'fiange portions which are respectively inwardly and outwardly of each other in the blank form as for example, outer portions 58 and 59 and

inner portions

60 and 61. The outer and inner portions of each end flange are integrally attached along a pair of parallelly spaced fold lines, as at 62 and 63 for end =fiange 40' and at 64 and 65 for end flange 41. The fold lines, as for example fold lines 62 and 63, are sufliciently spaced in parallel to enable the adjacent end flaps as for example end fiaps 47 and 49 to extend between the inner fiange and outer fiange portions, when the cover is in the assembled condition.

The

inner flanges

60 and 61 are provided with respecuve tabs as at 66 and 67, and at 68 and 69, which project outwardly when the blank is in the unfolded condition. The top portion 44 of the cover is provided with slots as at 70 and 71, and at 72 and 73, which are adapted to receive the respective tabs and to cooperate therewith in maintaining the cover in an assembled condition when the blank 1' is folded. It will also be noted that the

inner flanges

60 and 61 are provided with elongated internal

curvilinear cuts

74 and 75 which provide outwardly extenlding

tongues

76 and 77 when the cover is in the blank form. These

tongues

76 and 77 project into and cooperate with slots 38 and 39 of shell 4 when the cover is assembled and telescoped onto the box body. The

opposite ends of the

inner fianges

60 and 61 are cut away to form

slots

106, 107, 108 and 109 at the outer end extremities, of

cuts

54, 55, 56 and 57 respectively. These slots are of substantally' the same width as the thickness of the blank 1' to enable the inner portion of the fiange to extend laterally between the side flanges 45 and 46 when the cover is assembled.

The cover 1 is assembled by first bending the side flanges 45 and 46 along scored

fold lines

43 and 42 until the fianges 45. and 46 are perpendicular to the top portion 44 of the cover. Thereafter the end fiaps 47, 48, 49 and 50' are bent inwardly along the

respective fold lines

50, 51, 52 and 53 until the fiaps are perpendicular to their respective side fianges. Next the

end fianges

40 and 41 are foldedy along respective fold lines 54' and 55' until outer fianges 58 and 59 are in abutting face to face relationship with the end fiaps 47 and 49, and 48 md 50', respectively. Next the

inner fiange portions

60 and 61 are folded inwardly and over the respective adjacent end fiaps and the

end tabs

66, 67, 68 and 69, inserted in their cooperating holes 70, 71, 72 and 73 respectively.

As shown in FIG. 3, the tray blank 3' is rectangular in Shape with the corners cut and removed to form rectangular end panels and 6 and rectangallar side walls 7 and 8. End panels 5 and 6 are integrally joined to the bottom portion 78 of the tray along transverse scored fold lines 79 and 80 whereas the side walls 7 and 8 are integrally joined to the bottom portion 78 along longitudinally extending scored

fold lines

81 and 82 respectively. The

side walls 7 and 8 have

slots

13 and 14 which are cut intermediate the respective ends of the walls thereby dividing the walls into rectangular panels 9 and and rectangular panels 11 and 12 respectively.

Slots

13 and 14 are of sufiicient thickness to enable the double-walled partition 28 of shell 4 to extend therethrough when the box body is assembled.

The tongues 31 and 32 in end panels 5 and 6 respectively are formed by the respective cuts 83 and 84 which enable the tongues to be depressed pivotally inwardly of the respective plane of the end panels along integral hinge connections represented by broken lines 85 and 86.

The tray is formed from the blank 3' by bending the end panels 5 and 6 and side wall panels 9, 10, 11 and 12, along

fold lines

80 and 79, and 81 and 82, respectively, until the panels are perpendicular to the bottom panel 78 of the tray.

The blank 4' from which the shell 4 is formed is shown in FIG. 4 and is elongated and rectangular in shape. The blank 4' is divided longitudinally into elongated

symmetrical portions

87 and 88 by an elongated center cut 89 and scored fold lines 90 and 91 along the latter of which the

opposite portions

87 and 88 are integrally attached. Extending transversely of the blank on both sides of the cut 89 are spaced and scored

fold lines

92, 93, 94 and 95. Integrally attached

partition wall panels

18 and 19 are respectively integrally attached to side panels and 16 respectively along fold line 95. The

side panels

15 and 16 which are separated by cut 89 are integrally attached to end panels 17 and respectively along fold line 94.

Panels

17 and 20 which are also separated by cut 89 are integrally attached to

side panels

22 and 24 respectively along fold line 93. The cut separated

side panels

22 and 24 are integrally secured to end

portions

96 and 97 respectively along fold line 92.

It will be noted that each of the

end panels

17 and 20 is provided with a slot adjacent to and spaced from cut 89, as at 38 and 39, for the reception of the tongues in the cover 1. Further spaced from the cut 89 each of these panels is provided with a hand hole as at 29 and 30. Respective hand holes 98 and 99 are also provided in the

panels

18 and 19 which form the doublewalled partition 28.

To assemble the shell 4, the blank is first folded along

lines

92, 93, 94 and 95, as shown in FIG. 5 and the opposite ends 100 and 101 of the blank are joined in end abutting relationship by means of suitable adhesive type tape 102.

Thereafter

panels

18 and 19 and their

respective end portions

96 and 97 are folded along lines 91 and respectively until the

panels

18 and 19 are in face to face relationship as shown in FIG. 1. The outer shell may be then telescoped over tray 3, and cover 1 telescoped over the top of the shell as shown in FIG. 6.

Referring now to FIGS. 6 and 7, in attaching the outer shell 4 to tray 3, the shell 4 is first shoved down upon the tray 3 until the bottom end 103 of the partition 28 contacts the bottom portion 78 of tray 3. In this position, the hand holes, as for example hole 29, are in alignment with the enlarged portions of the tongues, as for example the enlarged portion 34 of tongue 32. The tongues in the end panels of the tray may then be pressed outwardly through the respective hand holes in the shell 4. Once the tongues are pressed outwardly, the shell 4 may' then be raised relative to the tray until the upper portions of the tongues as at 104 for tongue 32 engage the lower edges, as at 105, of the respective cooperatng slots. With the shell in the raised position, as shown in FIG. 7, it will be apparent that the box body may then be filled and cover 1 thereafter telescoped over the upper edges of the shell 4.

FIG. 7 illustrates the locking connection between the cover 1 and shell 4. As illustrated at end flange 40, the tongue 76 in the inner flange 60 extends inwardly when the tabs, such as at 66, of the inner flangc 60 are lockingly engaged in their respective slots. As such, when the cover is telescoped down upon the shell, the tongues engage the slots, as at 38, and the cover is locked in position thereat. By pulling outwardly on the end flanges, the tongues may be released from the slots and the cover lifted from the shell.

As the commodities contained in the box body settle and take up less space therein, the outer shell 4 may be presssed downwardly over the tray 3 since the walls of the box body are adjustable in height to the extent that the connections between the tray 3 and sheet 4 permit relative Vertical movement.

The box body has a further advantage in that it may be employed Afor commodity displaying purposes in stores and the like either as is or in a severed condition. For example, when the cover 1 is removed, the commodities in the respective compartments may be viewed in the two compartment container. When desired, the box body may be separated into two distinct portions by cutting the bottom portion 78 of the tray transversely between the tray

side wall slots

13 and 14 and by cutting the partition along the top edge 27.

While only a certain preferred embodiment of this invention has been shown and described by way of illustration, many modifications will ocur to those skilled in the art and it is, therefore, desired that it be understood that it is intended in the appended claims to cover all such modifications as fall within the true spirit and scope of this invention.
