FIG. 2 is a diagrammatic sectional view in partial section of a portion of the composite package of FIG. 1;
FIG. 3 is a diagrammatic sectional view in partial section of a portion of the composite package of FIG. 1; and
FIG. 4 is a diagrammatic top sectional view in partial section of a portion of the composite package of FIG. 1.
DETAILED DESCRIPTION OF THE INVENTION In the embodiment of FIG. 1, an item, such as a household refrigerator 10, is resting upon and supported by a base element 12 of the composite package 11 of this invention.
The base element 12 is of dimensions larger than the bottom of the refrigerator 10 for accommodating the refrigerator within the boundaries of the base 14 of the base element 12. The base 14 is preferably of a concave configuration for providing strength to the base element l2 and reducing the area of contact of the base 14 with the surface supporting the composite package.
The base element 12 has a plurality of corner portions 16, 18, 20, (fourth corner portion not shown), common to and associated with corners of the refrigerator 10. A plurality of first base flanges 22, 24 are each associated with a respective corner portion and extend in a downward direction normal to the base 14. A plurality of second base flanges 26, 28 are each associated with a corner portion and extend in a direction outwardly from a respective first base flange 22, 24, thereby forming a shelf 25.
The first and second base flanges need only be associated with a respective corner portion of the base element 12. However, in order to provide greater strength and simple construction, a preferred embodiment shown in FIG. 1 has first and second base flanges which are each continuous, peripheral flanges encompassing the base 14. The base can, however, be of other construction. For simplicity of description, the first and second base flanges will hereafter be described as peripheral flanges and will be designated by respective numerals 22 and 26.
A top element 30 is formed of first and second top peripheral flanges 32, 34. The first top flange 32 encompasses an area larger than the top of the refrigerator 10 or other item for nesting of the item therein. The first top flange 32 extends toward the underlying base 1 element 12 and the second top flange 34 overlies the refrigerator 10 and extends in a direction normal to the first top flange 32 and inwardly toward a respective opposed side of the top element 30.
The base element 12 and top element 30 can be formed of wood, paper, plastic, a metal such as aluminum, or other material to provide strength sufficient for packaging relatively heavy items. The top element 30 is of an open frame construction to reduce the weight of the resultant package and avoid waste.
The top element 30 has corner portions 36, 38, 40, and 42, each associated with a respective corner portion of the refrigerator 10 and the corners of the base element 12. A notch 46 extends through each corner portion 36, 38, 40, 42 of the first top flange 32 as hereafter more fully described.
A plurality of posts 48 are provided for connecting the base element 12 and top element 30 and supporting and protecting the package and the packaged item. Each of the posts are of generally a V configuration, associated with a respective corner portion of the base element 12 and top element 10, and are positioned over and extend along the length of a respective corner of the refrigerator 10.
Each of the posts 48 have upper and lower ends, are each positioned with the lower end in contact with the base, the upper end contacting the second top flange 34, and the upper end portion positioned inwardly of the first top flange 32. Each of the posts 48 have a corner portion with a notch 50 extending through the corner portion of the post adjacent the base element 12 and a notch 50' extending through the corner portion at the elevation of notch 46 of the first top flange 32.
In the assembled position, the refrigerator is positioned on the base 14 at a location spaced inwardly of the base element flanges 22, 26 and is aligned relative to the corner portions, the posts 48 are positioned on the first base flange 22 over the refrigerator corners, and the top element 30 is positioned over the upper ends of the posts.
In this position, the subassembled package is encased in an organic sheet material and the sheet material is shrunk to the subassembly. The organic sheet material can be, for example, low density polyethylene film having a thickness of about 4 mils which is shrunk to the subassembly by heat for forming a shrink-wrapped composite.
A bottom cap 54 has a base element 56 covering the bottom of the shrink-wrapped composite and a bottom cap flange 58 encompassing and extending about the periphery of the base element 12 in a direction toward the top element 30. The bottom cap 54 can be of a unitary construction and formed of paperboard, for example 275-pound corrugated paper-board, for providing a bottom cap 54 that is sturdy, easy to construct, and will withstand relatively severe abrasion and impact forces.
The bottom cap flange 58 extends to a higher elevation than notches 50 and has slits 60 formed adjacent the notches 50 in the assembled condition of the bottom cap 54 over the bottom end portion of the shrinkwrapped composite.
A top cap 62 has a cap top element 64 covering the top of the shrink-wrapped composite and a flange 66 preferably extending about the periphery of the top element 30.
Referring to FIG. 2, the flange 66 of the top cap 62 has at least one infolded flange portion 68 for forming a pocket 70. The infolded flange portion 68 extends between adjacent posts 48 and is of a Z configuration, thereby forming a pocket 70 which opens downwardly in a direction toward the bottom cap 54.
In the embodiment of FIG. 2, the flange portion 66 has first, second and third top cap flange portions 72, 74, 76. The third top cap flange portion 76 is immediately adjacent the organic sheet material 52 and has a width W greater than the width X of the first or second top cap flange portions 72, 74.
In order to provide a more sturdy construction, it is preferred that the first and second top cap flange portions 72, 74 are of a common width X and are positioned with the juncture 78 of the first and second top cap flange portions 72, 74 being in contact with the cap top-element 64 of the top cap 62.
The flange portions 68 having the formed pocket 70 can encompass the shrink-wrapped composite or be on only one or more sides thereof. If the flange portion 68 is not encompassing, the other portions 80 of the flange 66 (FIG. 1), if utilized, can be of a singular flange construction. The top cap 62 can be formed of a unitary construction and of a material as described above with reference to the bottom cap 54.
First and second means such as wires 82, 84, for example, each encompass the respective bottom element flange 58 and top cap flange 66 at the elevation of the respective notches 50, 60 and 50, 46, 60.
In the embodiment of FIGS. 3 and 4, the wire 82 passes through the slit 60 (FIG. 4) of the bottom cap flange 58 and enters the notch 50 for assuring against slippage of the wire 82 along the posts 48.
Referring to FIG. 1, wire 84 is positioned along a lower end portion of the pocket adjacent the notch 46 and, as described above, passes through the slit 60 at the corners of the flange 66 and into notch 46 of the first top flange 32 and notch 50' of the posts 48.
In the installed position of the wires 82, 84, the posts 48 are urged into engagement with the refrigerator 10, base element 12, and top element 30, and the caps 54, 56 are releasably maintained with the shrink-wrapped composite.
In the assembled condition, upstanding fingers of a forklift truck, for example, can be inserted into the pocket 70 for lifting and transporting the composite package of this invention. The third top cap flange portion 76 will protect the refrigerator 10 from damage by the forklift fingers and the bottom and top caps 54, 62 will reduce damage to the refrigerator 10 from contacting adjacent, underlying, or overlying objects. Since shrink-wrapped organic material comprises less material than encompassing paperboard containers generally utilized for packaging refrigerators and other largesize articles, a savings of material will be utilized by the use of the composite package of this invention and the package will provide viewing of the packaged article and will be of a construction adapted for automatic packaging.
Other modifications and alterations of this invention will become apparent to those skilled in the art from the foregoing discussion, and it should be understood that this invention is not to be unduly limited thereto.
