Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application is a divisional of co-pending U.S. utility
application Ser. No. 09/376,883 filed Aug. 18, 1999.
TECHNICAL FIELD
[0002] This invention relates to a nestable pallet for storing or
transporting goods.
BACKGROUND ART
[0003] Pallets that nest together allow such pallets to be easily
stored and transported when not in use. Nestable pallets used in
industry today typically have openings in their upper surface which
receive corresponding shaped feet of a similar nestable pallet.
While these openings provide a means for nesting pallets together,
there are also many disadvantages which accompany these openings.
For example, current nestable pallet designs may not be used to
ship products in bulk without a container because the product,
depending on its size, may fully or partially fall into the upper
surface openings. Even if a cardboard slip sheet is positioned
between the product and the openings, under load the slip sheet is
still weakest in the areas of the opening, particularly when such
pallets are stacked upon each other during use. Thus, the weight
and load of the upper pallets may cause the slip sheets to fail in
these weakened areas, causing the product stacked on the lower
pallets to push through the slip sheet and end up in the
openings.
[0004] Thus, an improved pallet is desired which allows for ease
and convenience of storage and transportation during non-use and
which during use allows products to be safely and securely placed
and transported thereon. The pallet should be reasonably
inexpensive, lightweight and sturdy. The improved pallet should
also be easy to store.
DISCLOSURE OF INVENTION
[0005] It is a principal object according to the present invention
to provide an improved pallet which is nestable during non-use
periods such as when such pallets are stored and transported.
[0006] It is another object according to the present invention to
provide a nestable pallet which allows for goods to be securely
loaded thereon during use, and during the stacking of loaded
pallets.
[0007] It is another object according to the present invention to
provide a pallet which is relatively lightweight, inexpensive to
manufacture and assemble, and consistently dimensioned.
[0008] It is yet another object according to the present invention
to provide a pallet which may be stored, racked or stacked in a
stable manner, thereby allowing one loaded pallet to be stacked on
and supported by another loaded subjacent pallet.
[0009] In carrying out these and other objects and goals according
to the present invention, a pallet is provided which includes a top
deck which has a substantially planar upper surface upon which a
plurality of objects and goods may be positioned during use. The
pallet includes a top deck portion which has an upper surface and
at least one opening formed therein. The pallet also includes a
foot portion corresponding to the at least one opening. The foot
portion has an inner surface, an outer surface, and an upright
member which projects upwardly toward the top deck and has a hollow
area disposed thereunder. In a nesting orientation, the hollow area
receives the upward projecting member of a subjacent pallet.
Preferably, the upper surface of the top deck portion is flat and
substantially planar, upon which a plurality of objects are capable
of resting. In one embodiment, the hollow area includes at least
one nesting stop portion. The opening, the inner surface and the
upright member define a pocket for receiving the foot portion of a
like pallet in a nesting orientation. In another embodiment, the
pocket includes at least one aperture for drainage. In still
another embodiment, the pocket includes at least one nesting stop
portion. The upper surface may also include a plurality of
apertures for drainage.
[0010] In yet another embodiment of the pallet according to the
present invention, a pallet is disclosed which is orientable in a
nesting orientation with a like pallet. The pallet includes a
plurality of cup-shaped support members. Each support member has an
inner surface, an outer surface, and an opening. The support
members further have an upright member which projects upwardly and
defines a hollow area thereunder, such that the inner surface,
opening and upright member together define a pocket therein. The
pallet also includes a deck portion which has an upper surface with
the openings of the support members formed therein for entry into
the pocket. In the nesting orientation, the hollow area receives
the upright member of a subjacent like pallet. In the nesting
orientation, the pocket receives the support member of an
above-positioned like pallet.
[0011] The above objects and other objects, features, and
advantages of the present invention are readily apparent from the
following detailed description of the best mode for carrying out
the invention when taken in connection with the accompanying
drawings wherein like reference numerals correspond to like
components.

BEST MODE FOR CARRYING OUT THE INVENTION
[0057] FIG. 1 of the drawings shows a top perspective view of a
first embodiment of a nestable pallet 10 according to the present
invention. Pallet 10 (as well as subsequent embodiments disclosed
herein according to the present invention) is preferably formed of
a thermoplastic or other polymeric material and is preferably, but
not necessarily, formed via an injection molding process.
Engineered materials may be used, as well as a synthetic resin such
as polyethylene or polypropylene with a filler added to stiffen the
resin. Of course, it is fully contemplated that the pallet
disclosed herein may be manufactured by various other molding
techniques and manufacturing processes applicable to the design and
material selected, including but not limited to blow molding,
thermoforming, vacuum molding, etc. It is further contemplated that
the material from which the pallet according to the present
invention is formed may include materials other than plastics and
polymer blends, and may include, by example and not limitation such
other materials such as wood, corrugated paperboard, compressed
sawdust, and metallic materials such as aluminum or tin.
[0058] As illustrated in FIGS. 1-7, pallet 10 includes a top deck
portion 12 which has an upper surface 14 and a lower surface 16.
With reference to FIGS. 2 and 3, in plan view, top deck portion 12
preferably has a rectangular shape with rounded corners, but may
also take other shapes, including but not limited to a square,
circular, triangular or other shapes as desired or required by the
use and application. Pallet 10 is preferably and generally
symmetrical about each centerline. Upper surface 14 is preferably a
substantially flat planar surface for allowing goods and objects to
securely rest thereon. Top deck portion 12 includes a first pair of
opposing edges 18 and 20, and a second pair of opposing edges 22
and 24.
[0059] Pallet 10 also includes a plurality of cup members 26 which
extend from the underside of top deck portion 12 and allow like
pallets to nest with each other. Cup members 26 typically have an
axis 43 which is perpendicular to upper surface 14. Members 26 may
also be referred to as feet, columns, or pods, etc. and have a
bottom surface 25 which serve to support pallet 10 upon a resting
surface, such as the ground or a floor. In a nesting orientation,
shown in relation to later embodiments such as in FIGS. 11, 19, 27
etc, members 26 are also received by a like pallet 10.
[0060] As illustrated in FIG. 43, for example, the goods or objects
placed upon upper surface 14 may be a plurality of bottles 90 used
in the bottled beverage industry. Such bottles are often placed
upon such pallets individually in bulk, or in lightweight cardboard
containers. As long as the bottles are of uniform height, it is
desirable to stack several loaded pallets on top of one another so
that they can be moved about collectively by fork lift, and
efficiently stored in a stacked configuration either on a floor or
on a shelf or rack.
[0061] In the embodiment illustrated, pallet 10 preferably includes
nine cup members 26, including a central member 28, corner members
30, side central members 32, and end central members 33 (best shown
in the bottom plan view of FIG. 3). Of course, pallet 10 may
include any number of cup members 26 as is practical. As shown in
FIGS. 1-7, and as best illustrated in FIGS. 4 and 5, members 26
(and particularly corner members 30, side central members 32, and
end central members 33) are spaced apart in order to define a
plurality of openings 34 therebetween. In some embodiments,
openings 34 may be used for receiving the forks of a fork lift or
pallet jack therein, thereby allowing pallet 10 to be lifted and
transported quickly and easily via the use of a fork lift, pallet
jack, or similar machinery. Members 26 are shown having smooth,
rounded outer surfaces 27 in order to prevent damage from fork lift
trucks and the like. However, any suitable contour may be used on
members 26 depending on the application. Members 26 also serve to
bear and distribute the load of the objects placed upon top deck
12, and more particularly the objects intended to be supported on
upper surface 14 of top deck 12. Further, members 26 are
illustrated as tapered in order to enhance the nesting properties
between like pallets 10.
[0062] In one embodiment, upper surface 14 is preferably non-skid
in order to prevent objects from sliding off during movement or
transport of pallet 10, or when stacking other pallets thereon.
Again, however, any suitable surface texture or geometry may be
used on upper surface 14 depending on the application without
departing from the spirit and scope of the invention.
[0063] In a preferred embodiment, top deck portion 12 also has a
plurality of apertures 36 formed therethrough. Apertures 36 perform
various functions, including decreasing the overall weight of
pallet 10 due to a reduction in the amount of material needed for
top deck portion 12. Less material also means that pallet 10 is
less expensive to manufacture, assuming that all other parameters
are equivalent. Apertures 36 also allow for drainage in the event
pallet 10 becomes wet, so that the liquid/debris is not accumulated
thereon. Thus, such apertures 36 are particularly helpful when
washing the pallet. Each aperture 36 is shown in FIGS. 1-7 as being
triangular in shape. However, apertures 36 may be any suitable
shape, dimension, frequency, and density and disposed in a variety
of combinations ranging from densely perforated to no perforations
(see FIGS. 8-11) depending on the desired application. Thus, top
deck portion 12 may have a continuous upper surface 14 without
apertures 36, as shown in FIGS. 8-11. Also, in conjunction with a
vacuum operated removal device for removing objects from a pallet,
apertures 36 lessen the suction power so that the pallet is not
lifted with the objects.
[0064] Referring to FIGS. 1 and 2 and the cross-sectional views of
FIGS. 6 and 7, upper surface 14 of top deck 12 also includes a
plurality of openings 38. While openings 38 in this embodiment have
a circular shape, the shape may vary as shown in later disclosed
embodiments. Each opening 38 corresponds to one of the members 26.
As shown in the sectional views of FIGS. 6 and 7, each opening 38
defines an inner surface 40 of its corresponding member 26. FIG. 6
is a cross-sectional view of pallet 10 taken along the line 6-6 of
FIG. 2. FIG. 7 is a sectional view of pallet 10 taken along the
line 7-7 of FIG. 2.
[0065] In keeping with the teachings according to the present
invention, each member 26 includes an upright member 42 (or cone
member) which is preferably centrally disposed and is generally
tapered, as shown in the sectional views of FIGS. 6 and 7. Upright
member 42 has an axis (which may be equivalent to axis 43 as in the
first embodiment) which is perpendicular to upper surface 14.
Opening 38, inner surface 40, and upright member 42 together define
a pocket 44 for receiving from above a like member 26 during a
nesting orientation of pallets 10. Pocket 44 may include one or
more ribs 46 or other member which serve as a nesting stop, so that
pallets 10 may be nested to a predetermined depth.
[0066] Likewise, each upright member 42 is defined by a generally
hollow opening 48 or area disposed thereunder, formed when outer
surface 27 of a given member 26 is turned upward toward top deck
12. Thus hollow opening 48 is designed to receive from below a
subjacent like upright member 42 of a similar pallet 10 in a
nesting orientation. One or more ribs 50 or other members may also
be disposed within hollow opening 48 for serving as a nesting stop,
again so that pallets 10 may be nested to a predetermined depth. In
addition, lower surface 16 of top deck 12 preferably has a
plurality or pattern of ribs 51 formed thereunder (see FIG. 3).
These ribs 51, as well as ribs 46 and 50, may also be utilized to
provide stiffness and improved structural integrity to pallet
10.
[0067] By projecting into pocket 44, upright member 42 serves as an
"island" or barrier within pocket 44, so that goods placed upon
pallet 10 are not able to fall into or become lodged within pocket
44. Thus, depending on the application and the size of the goods to
be supported on pallet 10, upright member 42 may be appropriately
sized so that no portion of such goods are received within pocket
44. Similar, a slip sheet 92 may be disposed upon upper surface 14
of top deck 12 of pallet 10 prior to the placement of goods
thereon, as shown in FIG. 43. During such use, upright member 42
provides additional support and load-bearing and load-distribution
properties to pocket area 44. For example, a slip sheet in the area
of pocket 44 and having an upright member 42 is stronger and better
able to bear loads than a slip sheet over a pocket with no upright
member. This is particularly helpful when loaded pallets 10 are
stacked upon similar loaded pallets 10. Thus, a slip sheet in the
area of opening 38 (pocket 44) is better capable of supporting the
weight and load of not only the goods resting directly thereon, but
also the weight and load of similar pallets 10 stacked
thereupon.
[0068] FIG. 3 of the drawings illustrates a bottom plan view of
pallet 10. As shown therein, lower surface 16 of top deck 12 is
substantially flat and planar for stable orientation on a similarly
designed pallet 10 for nesting and stacking purposes. FIGS. 1, 2,
3, 6 and 7 illustrate that each upright member 42 is tapered and
has an upper surface 52. Moreover, with reference to FIGS. 6 and 7,
at least one aperture 54 may be disposed at the lower surface of
each pocket 44 to allow for the drainage of liquid, so that liquid
does not accumulate in pocket 44 when washing pallet 10 or when
pallet 10 is left exposed to the environment.
[0069] With reference to FIG. 43, during a stacking orientation, a
first slip sheet may be placed upon pallet upper surface 14. Then a
layer of objects 90 (shown as bottles) is loaded on pallet 10.
Typically, a planar member 92 is positioned on the upper surface of
bottles 90. Planar member 92 may be referred to as a slip sheet in
the art, and is typically formed of cardboard or fiberboard. As
illustrated, another pallet may be disposed on top of planar member
92, and then another planar member 92 may be positioned on top of
that layer of bottles 90.
[0070] FIGS. 8-11 illustrate an alternate design to the first
embodiment of pallet 10 illustrated and described in association
with FIGS. 1-7, and in accordance with the present invention.
Particularly, the alternate first embodiment pallet 10' is similar
to pallet 10 but without apertures 36 in upper surface 14' of top
deck 12'. With reference to FIGS. 8-11, note that similar features
to those disclosed in the first embodiment of FIGS. 1-7 are
assigned a like reference numeral with a prime (') designation.
FIG. 8 is a top perspective view of pallet 10' of the alternate
first embodiment. FIG. 9 is a top plan view of pallet 10'
illustrating that upper surface 14' is continuous (does not include
apertures 36). FIG. 10 is a bottom plan view of pallet 10'. FIG. 10
illustrates the plurality of ribs or rib pattern 51' on lower
surface 16' of top deck 12'. FIG. 11 is a top perspective view
illustrating pallet 10' of the alternate first embodiment nested
within a like pallet 10'.
[0071] With reference now to FIGS. 12-19b of the drawings, shown
therein is a second embodiment of a nestable pallet 110 according
to the present invention. With reference to FIGS. 12-19, note that
similar features to those disclosed in the first embodiment of
FIGS. 1-7 are assigned a like reference numeral with the addition
of a "1" in front of the reference numeral. FIG. 12 is a top
perspective view of nestable pallet 110. Note that apertures 136 in
top deck 112 are illustrated as generally elliptical 136 or round
137, but as previously disclosed, may be any shape practical.
Further, as shown in FIG. 13, each member 126 is generally
rectangular in shape with rounded corners. As illustrated in FIG.
12, note also that each corner member 130 and each side central
member 132 has one upright member 142 disposed therein. On the
other hand, each end central member 133 has a first upright member
160 and a second upright member 162. Thus, inner surface 164 of end
central member 133 defines a first pocket 166 with first upright
member 160, while first upright member 160 and second upright
member 162 define therebetween a second pocket 168. Moreover,
center member 128 has a first upright member 170, a second upright
member 172, and a third upright member 174, defining respectively
first, second, and third pockets 176, 178, and 180,
therebetween.
[0072] Relative to the first embodiment shown in FIGS. 1-7, the use
of multiple upright members in the various cup members 126 thereby
decreases the relevant pocket size, thereby decreasing the
possibility that goods (or any portion of goods, such as bottles
