Kotowick, Richmond, British Columbia, Canada Crown Zellerbach Corp, 1 Bush St., San Francisco, Calif. 94104) Filed Feb. 23, 1966, Ser. No. 529,335 20 Claims. (Cl. 229-31) ABSTRACT OF THE DISCLOSURE An open-top basket having a bottom wall with side walls foldably connected thereto along its side margins. The basket further includes curved end walls which are detached from the bottom Wall, but are connected to the side walls by means of pairs of foldably connected intermediate panels. The intermediate panels are tucked inwardly against the side walls and held in place by means of side flaps which are foldably connected to the side walls and folded over against the intermediate flaps. The legs of a U-shaped handle are inserted into the cavities located between the side flaps and side walls, and bosses on the legs project outwardly through apertures in the side walls, thereby retentively securing the handle to the side walls.

This invention relates in general to receptacles and, more particularly, to open-top baskets for holding fresh fruits, vegetables, and other commodities.

Groceries, farmers, hucksters and the like have for many years found it convenient to display and deliver fresh fruits, vegetables, and other commodities in small open-top baskets ranging in siZe from six quarts to two pecks. Traditionally, such baskets were constructed from wood splints bent in the configuration of upwardly and outwardly flared walls much on the order of a conventional bushel basket, but, in recent years, baskets con structed fro-m paperboard and fiberboard have become increasingly popular. Paperboard is, of course, considerably cheaper than wood splints and lends itself more readily to fabrication into box-like iforms. Moreover, paperboard possesses cushioning properties which protect delicate commodities, has smooth surfaces free of splinters, and can easily be provided with advertising or other printed information.

However, conventional paperboard boxes of present manufacture in many instances do not possess adequate strength and further are often unduly complicated. In many instances, such baskets must be assembled at the point of manufacture which not only increases production costs but also presents shipping and storage problems of considerable magnitude. Some distributors ship such paperboard baskets to the grocer or other user in the so-called broken-down condition, but this imposes an undesirable burden on the user for he must spend valuable time fitting together the intricate interfitting components of the baskets.

The present invention resides in a receptacle which possesses a configuration similar to the traditional wood fruit baskets, that is to say, it has upwardly and outwardly flared arcuate end walls which are interconnected by substantially rectangular side walls. The invention additionally embodies a unitary blank which can easily and rapidly be transposed into a basket-like receptacle of the present design.

Among the several objects of the present invention may be noted the provision of a basket which is ideally suited for marketing fresh fruits, vegetables, and other commodities; the provision of a basket of the type stated which is attractive in appearance, economical to trnanufacture, and sturdy in construction; the. provision of a 3,3663% Patented Jan. 30, 1968 basket which can be easily and quickly assembled from a unitary blank; and the provision of a basket blank which can be produced in a single-step stamping operation. Other objects and features will be in part apparent and in part pointed out hereinafter.

The invention accordingly comprises the constructions hereinafter described, the scope of the invention being indicated in the following claims.

Corresponding reference characters indicate corresponing parts throughout the several views of the drawings.

Referring now in more detail and by reference characters to the drawings, which illustrate a preferred embodiment of the present invention, 2 designates a receptacle including a basket portion 4 and a handle 6 which are interconnected in a manner presently to be described herein.

Referring now to FIG. 2, basket portion 4 is assembled from a unitary or one-piece basket blank 8 preferably die-cut or otherwise suitably formed from a corrugated paperboard stock. Blank 8 is centrally provided with a bottom wall panel 10 defined on its sides by

parallel scorelines

12, 14, and at its ends by

arcuate slits

16, 18, which intersect

scorelines

12, 14. Bottom wall panel 10 is cut away along scoreline 12 in the provision of rectangular cut-outs 20 having a width somewhat greater than the thickness of the paperboard stock. Similarly, along scoreline 14, bottom panel 10 is inwardly provided with rectangular cut-outs 22 located opposite cut-outs 2t Foldably connected to bottom panel 10 along scoreline 12 is a rectangular side wall panel 24, the end margins of which are defined by

scorelines

26, 28, which project perpendicularly from scoreline 12 at the points where such scoreline intersects

arcuate slits

16, 18, respectively. Preferably halfway between

scorelines

26, 28, side panel 24 is cut away along scoreline 12 in the provision of a rectangular cut-out 30 for purposes presently more fully appearing. The remaining longitudinal margin of side panel 24 is defined by a scoreline 32 which separates side panel 24 from a narrow upper rim panel 34 to which a rectangular side flap 36 is foldably secured along a scoreline 38 located in parallel relation to scoreine 32; The ends of side flap 36, as well as upper rim panel 34, are defined by

end margins

40, 42, which are colineal with

scorelines

26, 28, respectively, while the outer longitudinal margin of side fiap 36 is defined by a side margin 44 having rectangular tabs 46 projecting outwardly there from. Tabs 46 are located inwardly from

end margins

40, 42, at a distance equal to the inward disposition of cutouts 20 from

scorelines

26, 28, and are, moreover, sized for snug-fitting retentive engagement with cut-outs 20 as will presently be described in greater detail. Upper rim panel 34 is bisected by a rectangular cut-out 48 which extends into side flap 36 forming a rectangular notch 50 therein. Finally, it should be noted that the transverse dimension of rectangular side flap 36 is equal to the transverse dimension of rectangular side wall panel 24 while the transverse dimension of upper rim panel 34 is slightly greater than twice the thickness of the paperboard stock.

Similarly connected to bottom wall panel along scoreline 14 is a side wall panel 52 defined at its ends by

scorelines

54, 56, and provided with a rectangular cut-out 58. Foldably connected to side wall panel 52 along a scoreline 60 is a narrow upper rim panel 62 which is bisected by a cut-out 64 and foldably connected thereto along a scoreline 66 is a side flap 68 into which cut-out 64 extends in the provision of a notch 70. The outer margins of side flap 68 are defined by

end margins

72, 74, and a side margin 76 from which tabs 78 project outwardly.

Foldably connected to

side wall panels

24, 52, along

end scorelines

26, 54, are trapezoidally-shaped connecting

members

80, 82, respectively, which are diagonally bisected by crease scorelines 84 in the formation of matching triangular

intermediate panels

86, 88. To reduce the paperboards natural resistance to folding along the scoreline 84, the connecting

members

80, 82, are provided with slit scorelines 89 which are coincident with the scorelines 84. It should be noted that the slit lines 89 do not extend completely through the paperboard stock, but instead pass through only one liner and the corrugated medium intermediate the liners. As will be seen by reference to FIG. 2, trapezoidally-shaped connecting

members

80, 82, are outwardly defined by intersecting

end margins

90, 92, which are, in effect, the outer margins of triangular

intermediate panels

86, 88, respectively. The remaining margins of trapezoidally-shaped connecting

members

80, 82, are defined by outwardly diverging

corner scorelines

94, 96, respectively, which intersect

scorelines

26, 54, respectively, at an angle slightly less than 90.

Interposed between connecting

members

80, 82, is an end wall panel 98 having an arcuate bottom margin 100 which is formed by arcuate slit 16. Located opposite from bottom margin 100 is an upper margin 102 which is substantially linear between

points

104, 106, which are, in turn, located along the lines defined by lineal extensions of

scorelines

12, 14, respectively. From

points

104, 106, outwardly outer margin 102 is colineal with margins 92 of intermediate panels 88 of trapezoidally-shaped connecting

members

80, 82, respectively. Intermediate

divergent scorelines

94, 96, end wall panel 98 is provided with a plurality of outwardly diverging arcuately spaced scorelines 108.

Similarly connected to the opposite ends of

side wall panels

24, 52, along

scorelines

28, 56, are trapezoidallyshaped connecting

members

110, 112, which are diagonally bisected by crease scorelines 114 in the formation of matching triangular

intermediate panels

116, 118, having angularly presented intersecting

outer end margins

120, 122, respectively. Scorelines 114 are cut for a portion of their length in the provision of coincident slit lines 124 which are similar to slit lines 89. Interposed between trapezodally-shaped connecting

members

110, 112, and foldably connected to triangular panels 116 thereof along outwardly diverging

scorelines

126, 128, is an end wall panel 130 having an arcuate bottom margin 132 and a substantially linear upper margin 134. The end wall panel is further provided with a plurality of diverging arcuately spaced scorelines 136.

As has already been noted, it is preferable to cut the blank from corrugated paperboard stock, but it should be pointed out that any foldable sheet material will suffice and this invention is not limited merely to receptacles formed from corrugated paperboard. Moreover, the blank, including its cut-outs, scorelines and slits can be die-cut in a one-step stamping operation. In this connection, it should be pointed out that the paperboard stock should be oriented on the die prior to stamping so that the corrugations Will extend transversely across bottom wall panel 10,

side wall panels

24, 52, and side flaps 36,

68, of completed blank 8. Such an orientation lends maximum rigidity to completely assembled receptacle 2.

To transform blank 8 into basket portion 4, side wall panel 24 is bent inwardly along scoreline 12 while trapezoidally-shaped connecting

members

80, 110, are bent along

scorelines

26, 84, 94, and 28, 114, 126, so that triangular

intermediate panels

86, 88, and 116, 118, are tucked inwardly into facewise abutment, all as best seen in FIG. 3. When side wall panel 24 is presented at substantially a right angle with respect to bottom panel 10, triangular

intermediate panels

86 and 116 of trapezoidally-shaped connecting

members

86, 110, respectively, will come into facewise abutment with the inwardly presented face of side wall panel 24. Coincident slit lines 89, 124, of course, permit complete folding of connecting

members

80, 110, along their respective

diagonal scorelines

84, 114. At this stage of assembly,

outer end margins

90, 92, and 120, 122, of intermediate connecting

members

80, 110, will be adjacent and parallel to scoreline 32 and similarly

scorelines

26, 94, and 28, 126, will be adjacent one another and presented at substantially right angles to scoreline 32. Thereafter, upper rim panel 34 is folded over along scoreline 32 into overlying relation with the juxtaposed

outer end margins

90, 92, and 120, 122, and, subsequently, side flap 36 is folded over along scoreline 38 and into embracing relation with folded connecting

members

80, 110, whereupon end

margins

40, 42, of side flap 36 will engage diverging

scorelines

94, 126, respectively, allowing side flap 36 to bear against triangular

intermediate panels

88, 118, of connecting

members

80, 110, respectively, so as to prevent distending of such triangular intermediate panels or unfolding of connecting

members

80, 110. Tabs 46 fit into retentive engagement with rectangular cut-outs 20 and hold side wall panel 24 and side flap 36 in embracing relation with folded connecting

members

80, 110.

Similarly, side wall panel 52 is folded inwardly along scoreline 14 while trapezoidally-shaped connecting

members

82, 112, are tucked inwardly along their respective

diagonal scorelines

84, 114, thereby bringing triangular

intermediate panels

86, 88, and 116, 118, into facewise abutment. Subsequently, side flap 68 is folded over and into embracive relation with inwardly tucked connecting

members

2, 112, and tabs 78 are fitted into rectangular cut-outs 22, thereby completing basket portion 4 of receptacle 2. Of course, staples or any suitable adhesive may be used to hold side wall panels 24, S2, to their respective connecting

members

80, 110, and 82, 112, as well as to secure side flaps 36, 68, thereto. Although adhesives or staples would securely hold basket portion 4 in an assembled position and insure that it does not unauthorizedly break apart, such a precaution is generally not necessary, except under the severest conditions, for the snug-fitting engagement of

tabs

46, 48, with cut-

outs

20, 22, sufliciently holds the components of basket portion 4 in place.

The inward tucks of folded connecting

members

80, 82, 110, 112, embraced by

side wall panels

24, 52, and side flaps 36, 68, prevents

end wall panels

98, 130, from distending while the trapezoidal-shape of such connecting

members

80, 82, 110, 112, and the divergent relation between

scorelines

94, 96, and 126, 128, causes

end wall panels

98, 130, of assembled basket portion 4 to flare upwardly and outwardly as best seen in FIG. 1 as gently contoured substantially continuous arcuate end walls 138, 140, having a plurality of slight bends or folds, each located at one of the

scorelines

108, 136. Moreover, combined

side wall panels

24, 52, and side flaps 36, 68, form extremely

rigid side walls

142, 144, having a double thickness. Horizontally presented

upper rim panels

34, 62, lend rigidity to

side walls

142, 144, and prevent the same from distending when basket portion 4 is filled with relatively massive articles. Inasmuch as the corrugations extend transversely across bottom panel 10, such bottom panel is capable of carrying maximum loads. If, on the other hand, the corrugations were oriented to extend longitudinally in bottom panel 10, such panel would give way and fold along one of the corrugations under much lighter load conditions. The arcuate apertures formed between

bottom margins

100, 134, of end walls 138, 140, and bottom wall panel are relatively narrow and retard passage of all but the smallest of commodities. These apertures can, of course, be sealed by use of a paper lining within basket portion 4. Obviously, basket portion 4 can be assembled from blank 8 with a minimum amount of effort and expenditure of very little time. Furthermore, it is so simple in construction that no difficult-to-follow set of instructions need be supplied to the ultimate purchaser for assembly.

Provided for cooperation with basket portion 4 is handle 6 including a U-shaped bow 146 fabricated from wood, a synthetic resin, or any other suitable material. Glued or otherwise securely fastened on the outwardly presented surface of bow 146 at its terminal ends are block-like

rectangular bosses

148, 150, which are sized to fit within cut-

outs

30, 58. After basket portion 4 has been completely assembled from blank 8 as heretofore described, the ends of handle 6 are fitted through cut-

outs

50, 64, in

upper rim panels

34, 62, and the handle pressed directly downwardly. The outer surfaces of

bosses

148, 150, will slide along the inwardly presented surface of side flaps 52 until cut-

outs

30, 58, are encountered, whereupon

bosses

148, 150, will spring outwardly by virtue of the natural bias of bow 146 and engage cut-

outs

30, 58, respectively, so as to lock handle 6 within basket portion 4 in the formation of the completed receptacle 2. Thus, handle 6 is presented in upwardly spaced relation to bottom panel 10 for convenient grasping by the ultimate user.

In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.
