- The present invention claims the benefit of U.S. Provisional Patent Application No. 62/551,578 filed Aug. 29, 2017, the contents of which are incorporated herein by reference.
- N/A
- The present invention provides a low cost, light weight shelving display that is easily assembled from components that utilize recycled material and the display is ideal for light weight food products such snack food in flexible bags.
- Product displays are commonly used in retail locations to display items for sale. It is common for displays to be erected from paperboard blanks that have fold lines. The instructions can be somewhat complicated or time consuming, thus expensive to implement in large scale or high volume. Since such displays are commonly used for a short period of time and then disposed of, it is desirable to utilize recycled components that are themselves recyclable. It is also desirable for such product displays to be easily assembled so that staff members at the retail location can erect the displays without assistance from the product supplier. It is also desirable to minimize the costs of the displays in terms of materiel used.
- The present invention provides a pallet chassis assembly having a unitary body supporting a shelf tray. The unitary body is of a molded pulp material having a pair of elongate support beams. The support beams extend transverse to one another at an angle from 20° to 90° and intersect one another at an intermediate portion of each to form a generally x-shaped body. The x-shaped body has a planar upper surface. The body further has a plurality of legs extending along a line generally perpendicular to the upper surface. Each leg has a wall enclosing a chamber dimensioned to receive a leg from another similarly configured unitary body to define a nesting arrangement. Each leg has an opening into the chamber at one end and a ground engaging structure at the opposite end. The shelf tray engages the plurality of legs and is of a corrugated sheet having an upper surface, and a lower surface.

-
FIG. 1 shows aproduct display assembly 10 having a stack ofpallet chassis assemblies 12, atop cap 14, and astandard pallet 16. Eachpallet chassis assembly 12 has aunitary body 20 and ashelf tray 22. The pallet chassis ofFIGS. 1-3 is known as a full pallet chassis as it is dimensioned to cover a standard pallet of 48×40 inches. The pallet chassis shown inFIGS. 5 and 6 show a half pallet chassis and thus two half-pallet chassis assemblies are used pershelf 24 when used with astandard pallet 16. Similarly, thepallet chassis 12 shown inFIGS. 7 and 8 show a quarter pallet chassis, and, thus, four quarter-pallet chassis assemblies are used pershelf 24 when used with astandard pallet 16. Otherwise, ahalf pallet 16′ (FIG. 6 ) can accommodate two quarter pallet chassis or a single half pallet chassis pershelf 24. Also, aquarter pallet 16″ (FIG. 8 ) can accommodate a single quarter pallet chassis pershelf 24. -
FIG. 1 shows thedisplay 10 using three full-sized pallet assemblies 12 forming 4shelves 24. While three full-sized pallet assemblies 12 are shown, fewer or greater number of such could be provided without departing from the scope of the present invention. For example, anywhere from 1 full-sized pallet assembly 12 to 10 full-sized pallet assemblies 12 could be used to form aproduct display 10 on a singlestandard pallet 16. Thus, a display can have from 1 to ten shelves, for example. - The
unitary body 20, which may sometimes be referred to as a skeleton, has a pair ofelongate support beams 30 and a plurality oflegs 32. Theelongate support beams 30 have a length dimension greater than a width dimension and intersect one another at anintermediate portion 35 of their length at an angle α to form a generally x-shaped body. The angle α is about 79° shown inFIG. 3 but can be anywhere from 20° to 90°. For example, the angle α for the half pallet chassis ofFIG. 5 is about 45°, and for the quarter pallet chassis ofFIG. 7 is about 80°. Thesupport beams 30 have a planarupper surface 34 to support theshelf tray 22 ortop cap 14. Thesupport beams 30 may also have a pair ofchannels 45 flanking the planarupper surface 34 to strengthen theunitary body 20. Thechannels 45 extend along a length dimension of thesupport beams 30. Other structures can be formed in the unitary body to strengthen thesupport beams 30, the legs or other parts of the display. - Each
leg 32 of the plurality oflegs 32 extends along a line generally perpendicular to theupper surface 34. Eachleg 32 has awall 50 enclosing a chamber 52 (FIG. 10 ) dimensioned to receive a leg from another similarly configured unitary body to define a nesting arrangement 53 (FIG. 2 ). Eachleg 32 has anopening 54 into thechamber 52 at one end and a groundengaging structure 60 at the opposite end. The chamber has a polygonal shape in cross section and preferably is triangular or rectangular.FIG. 10 shows a portion of thewall 52 tapers 62 radially outwardly from the opening 40 to the groundengaging member 60.FIG. 11 shows the groundengaging member 60 closes an end of thechamber 52 and has anupstanding member 64 to strengthen the groundengaging member 60. - It is desirable for the leg to be taller than a product to be used with the
display 10. In one preferred form of the invention, the leg will be substantially taller than a thickness of the cross beams. What is meant by “substantially” is from 2 to 50 times, more preferably 3 to 30 times, and most preferably 5 to 25 times. It is desirable that the display have viewing “windows” as large as possible for optimal display of products in the display. What is meant by “windows” are the rectangular-shaped openings formed between each set of legs forming end edges defining a vertical dimension of the windows and two adjacent shelf trays (or a shelf tray and a top tray) forming a top and bottom horizontal edges of the windows. - The
unitary body 20 of the full pallet chassis has aperipheral wall 80 that connects all of thelegs 32 and defines an inner space 82. The support beams 30 are positioned in the inner space 82 and connect to the peripheral wall at the four vertexes. The peripheral wall shown is generally rectangular but could be of other shapes such as polygons, circles and ovals. Suitable polygons will have from 3 sides to 10 sides and preferably are regular polygons having sides of equal length and separated by equal angles. Suitable polygons include triangles, squares, rectangles, pentagons, hexagons, heptagons, octagons, nonagons and decagons. Most preferably, the polygon is a rectangle. The peripheral wall 82 has an upperplanar surface 84 that is coplanar with theupper surface 34 of the support beams. The peripheral wall hassegments 86 that correspond to edges of the polygon so a rectangular peripheral wall will have a first and a second segment extending along a first direction and spaced from one another along a second direction perpendicular to the first direction. The rectangular peripheral wall also has a third and a fourth segment extending along the second line with the third segment connecting a first end of the first and second segments. The fourth segment will connect the second end of the first and second segments. - The unitary body is shaped or molded from a pulp material and will be referred to as molded pulp. Molded pulp is a material of a recycled paperboard and newspaper and is formed into the desired shape using molds. Suitable techniques include slush molding, vacuum forming, transfer molding, take-off molding, and cure-in-the-mold technology to name a few. The molded pulp material can have additives such as: corn starch based biodegradable polymers (injection molded or vacuum/thermo formed); structural foam additives (injection molded); sustainable wood-plastic composites from
bio-based polyamide 11, beech wood fiber or other similar mix; HIPS (high impact polystyrene); and MIPS (medium impact polystyrene). The molded pulp provides a rigid, light weight substrate for supporting shelves. The molded pulp displays are particularly suitable for supporting light weight products such as bags of snack chips, cereals, dried fruits, and other salty snacks, and particularly where the product is in aflexible bag 70 as shown inFIGS. 4,6,8 . - In a preferred form of the invention, the molded pulp material will be capable of recycle using standard paperboard recycling techniques as opposed to recycling techniques for polymeric materials. Also, the unitary body is “disposable” meaning that it can be rid of by placing in standard waste disposal streams and capable of being buried in landfills. It is also desirable the molded pulp material be a “sustainable packaging material”—made of recycled material and capable of being recycled.
- The
shelf tray 22 and thetop plate 14 have the same construction and will be described with respect to theshelf tray 22. Theshelf tray 22 has a web of material having an upper surface, a lower surface, and, in a preferred form, is dimensioned to be placed on top of and cover an entire surface area of the planarupper surface 34. Theshelf tray 22 has anupstanding wall 90 disposed about the periphery of the web of material or sheet. The upstanding wall can have the same shape as the peripheral wall including polygonal, circular and oval. Preferably, the upstanding wall is in the same of a rectangle or a square. Theshelf tray 22 is fabricated from a material such as corrugated paperboard, corrugated plastic, plastic sheeting, paper sheeting, molded pulp, and the like. The upstanding wall is dimensioned to receive the legs of the unitary body in corners to prevent the unitary body from sliding or moving. The shelf tray has the upstanding wall extending upward and thetop plate 14 has the upstanding wall extending downward. The shelf tray engages the ground engaging portion of the legs and the top cap covers the top of the chassis and covers over theholes 40 into the chambers. - The shelf tray is formed from a blank of material that can be die cut to size and have a fold line separating the upstanding wall from the planar sheet and the upstanding wall can be folded from the blank.
- Erecting a
display 10 from the individual parts is easy and can be accomplished without tools and with a modicum of mechanical skills by an untrained user. The necessary components include a plurality of unitary bodies such as in a nestedstack 53, a plurality of shelf trays, and a top cap. A shelf tray is placed on top of the pallet and a skeleton is placed on top with the legs facing downwardly and received within the corners of the tray. A second shelf tray is placed on top of the first skeleton to form a second shelf. This process is repeated until the desired number of shelves is reached. The top cap can provide a shelf whose top is not covered. Product can then be loaded onto the shelves for display and sale. - Many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood within the scope of the appended claims the invention may be protected otherwise than as specifically described.
