PALLET AND PANEL STORAGE SYSTEM AND RELATED METHODS

FIELD OF THE INVENTION

The present invention generally relates to shipping containers, and more particularly to systems, apparatus and methods for transporting a palletized stack of bottles or other similar containers using a unique pallet base and a unique set of panels that may be engaged with the base in order to protect the stacks of bottles during shipping.

BACKGROUND OF THE INVENTION

Bulk glass bottles and other fragile containers are typically transported from a manufacturer to a bottler in stacks that are loaded on pallets. The glass or other containers are stacked on a pallet in layers with a slip sheet (e.g., thin cardboard sheet) in between each layer. After the final layer of the stack is completed, a frame or cap is placed on top to provide rigidity, and the unit of stacked containers is then stretch wrapped with plastic or otherwise shrouded. For example, a thermoplastic bag may be arranged around the pallet and heated to compress the bottles together in a single unit. The pallet is then ready for transportation.

Pallets are typically loaded into a semi-trailer or a freighter for transportation via semi-truck, watercraft, or train. To avoid damage to the bottles, the pallet is typically anchored to the interior walls of the semi-trailer with straps positioned around the pallet. Airbags are typically provided between the interior walls, the palletized stack, and other pallets or parcels to help prevent the delicate glass bottles from breaking. Nevertheless, during transport the bottles will still be subjected to vibrations transferred from the road or rough water during transportation, and bottle-to-bottle contact may cause some of the bottles succumb to surface flaws, cracks, scratches, and fractures. The use of plastic wrap and strapping does not provide uniform rigidity, and in some instances, the bottles may topple over and break, rendering the bulk glass bottles are unusable. There is therefore an ongoing need for improved stabilization of palletized stacks of bottles to avoid damage during shipping and transport. It is also desirable to be able to view the bottles in the stack, protect the palletized stack from contaminants, and to provide reusable pallet systems that are easy to assemble and disassemble, and ship back for reuse.

SUMMARY OF THE INVENTION

To address one or more of these and/or other needs or problems, the present inventor devised, among other things, one or more exemplary systems, kits, methods, devices, assemblies, and/or components related to bulk containers, particularly the containment, transport and shipment of bulk glass in warehouses and trailers.

The present invention provides systems, apparatus and methods for transporting a palletized stack of bottles or other similar bulk-produced containers using a unique pallet base and a unique set of side panels that may be engaged with the base and with each other in order to protect the stacks of bottles on the pallet base during shipping and transport. Embodiments of the invention dampen vibrations, protect the bottles from exterior contaminants, and allow the bottles to be viewed from the outside. Embodiments of the invention also provide reusable pallet systems that are easy to assemble and disassemble, and ship back for reuse. These and other features of the present invention are accomplished using a rectangular (usually square) pallet base having patterns of openings on its upper surface. Peripheral openings are provided on the pallet base for engagement with corresponding tabs or protrusions on the bottoms of each of the panels, allowing the panels to be installed on the four sides of the pallet base, around a stack of containers on the pallet base. Additional sets of openings may be provided on the surface of the pallet base for receiving rows of panels for return and reuse. Embodiments of the side panels may be operable to engage with adjacent side panels forming four side walls, and a lid may be installed to form a completed pallet container.

In embodiments of the invention, the interior surfaces of the panels may be provided with dampening material to prevent the transfer of vibrations to the stack of containers therein, providing a relatively static environment during bulk storage or transportation. Embodiments of the pallet containers of the present invention may further provide weather protection, and one or more of the panels may include viewports operable to allow a user to monitor or view the contents of the container. Embodiments of the completed containers of the present invention may include a one or more attachment mechanisms to link adjacent completed containers together to form a chain or matrix of containers that are highly stable during transport.

Embodiments of the present invention provide a front and back panel that may be interchangeable each having an exterior surface, an interior surface, and a perimeter comprising top, bottom, right, and left edges. The bottom edge may include one or more protruding male connecting members for engagement with corresponding female connecting openings along an edge of the pallet base. In other embodiments, the bottom edge may include one or more female connecting openings for engagement with corresponding protruding male connecting members along an edge of the pallet base. In other embodiments, the bottom edge may include both male and female connecting members which engage with corresponding female and male connecting members on the pallet base. It is to be appreciated that the male/female connecting members on the bottom edge and pallet base may be provided in alternating, symmetrical, asymmetrical, or other suitable complementary arrangements.

Similarly, in embodiments of the invention, the top edge of the front and back panels may include one or more female connecting openings operable to align with corresponding protrusions on a lid for the container. In other embodiments, the top edge may include one or more protruding male connecting members for engagement with corresponding female connecting openings along an edge of the lid. In other embodiments, the top edge may include both male and female connecting members which engage with corresponding female and male connecting members on the lid. It is to be appreciated that the male/female connecting members on the top edge and lid may be provided in alternating, symmetrical, asymmetrical, or other suitable complementary arrangements.

On the top and bottom edges of embodiments of the front and rear panels, the connecting members and openings may be on a plane of symmetry parallel to the interior and exterior surface of the panel. At the two upper corners of the interior surface of embodiments of the front and back panels, rods may be provided that protrude out orthogonally to the plane of the interior surface. The rods may each maintain symmetry in respect to a horizontal and a vertical axis. The rods be placed near the edges of the interior surface in order to be engageable with corresponding conduits in the left and right side panels, described below.

In embodiments of the invention, left and right side panels are provided that may be interchangeable, each such panel having an exterior surface, an interior surface, and perimeter comprising top, bottom, right and left edges. The bottom edge may include one or more protruding male connecting members for engagement with corresponding female connecting openings along an edge of the pallet base. In other embodiments, the bottom edge may include one or more female connecting openings for engagement with corresponding protruding male connecting members along an edge of the pallet base. Similarly, the top edge of the side panels may include one or more female connecting openings operable to align with corresponding protrusions on a lid for the container. In other embodiments, the top edge may include one or more protruding male connecting members for engagement with corresponding female connecting openings along an edge of the pallet base. It is to be appreciated that the male/female connecting members provided on the top edge and lid, and those provided on the bottom edge and pallet base, may be provided in alternating, symmetrical, asymmetrical, or other suitable complementary arrangements.

On the top and bottom edges of embodiments of the side panels, the connecting members and openings may be on a plane of symmetry parallel to the interior and exterior surface of the panel. The right and left edges may be provided with upper conduits operable to receive the rods of the front and back panels. The conduits may have an axis orthogonal to the interior surface of the left or right side panel. The conduits may have an axis on the plane of symmetry. In addition, the right and left edges of the side panels may be provided with one or more female openings operable to receive one or more connecting male members of the front or back panels.

In some embodiments, the rods may be made of metal and may have a magnetic charge that attracts them to corresponding metal conduits in the left and right side panels. In these and other embodiments, the surface of the panel adjacent to each rod may have one or more a magnetically charged members that are attracted to one or more corresponding metal members on the surface of the left or right side panel adjacent to the conduits. It is to be appreciated that in alternative embodiments, the magnetic and metal parts may be reversed. For example and without limitation, the rods may be made of metal and the conduits may be magnetically charged, and/or the members adjacent to the rods may be made of metal and the members adjacent to the conduits may be magnetically charged. The magnetic attraction between the rods and conduits (and/or between the members adjacent to them) allows for adjacent front/rear and left/right panels to be engaged with each other in an upright (vertical) position, allowing for more secure strapping to then be used to firmly secure the panels together.

In some embodiments, the male connecting members may be substantially circular in cross-section, and the female receptacle of the base pallet may have a conduit operable to receive the male connecting member. In some embodiments, the male connecting members may protrude from the bottom surface of the panel and may have a substantially round geometry, and may have a generally oval cross-section. In some embodiments, the female connecting members on the pallet base may have a geometry complementary to the male connecting member and may be operable to align the panel with the pallet base. In some embodiments, the male connecting member may protrude out from the base at least one half of an inch and may extend out no more than three inches. In some embodiments, the female connecting member may have a depth larger than the protrusion of the male connecting member. In some embodiments, the female receptacles of the side panels may have a substantially round geometry and provide a generally oval cross-section and have a depth of one inch, and the male members of the front and rear panels may have a depth complementary to the female receptacles. In some embodiments, the male connecting members may have geometric characteristics that have a tapering geometry where the protrusion from the bottom surface has the largest cross-section, and the apex of the protrusion has the smallest cross-section.

Some embodiments of the present invention provide panels with a plurality of viewing windows. Exemplary viewing windows may have a substantially circular, rectangular, or elliptical geometry and may provide an aperture for a transporter to monitor the contents of the container. Some embodiments of the invention provide a tension system that may align with a layer of bottles in a palletized stack of bottles. The tension systems provide dampening characteristics that absorb vibrations and prevent damage to the layers of bottles. In some embodiments, members of the tensioning system may be provided between viewing windows, and may come into contact with the bottles at the label height and may be integrated into the interior surface of the panel. In some embodiments, the tension system may be provided in the form of ribbing, and may have a sinusoidal geometry that caresses the bottles. In some embodiments, the ribbing in the system may be manufactured from durable foam such as polyethylene foam, high-density rigid foam, and EVA foam, as an example.

In some embodiments, the tension system may be constructed from a plurality of tension bands molded to the inside of the panel manufactured from a deformable plastic or nylon material with a geometry operable to provide a dampening resistance such as a leaf spring. In some embodiments, the leaf springs may be removably attached to the interior surface of the panel with a fastener (e.g., rivet, screw, hook and loop). In other embodiments, the tension system may include a plurality of connected air bladders positioned on the interior surface of the panel in line with the label height of the bottles in the stack, and the air bladders may be in a deflated state while the container's perimeter is assembled. Once the perimeter panels (back, front, right and left) are connected, the air bladders may be inflated and may have an inflated geometry that is substantially elongated and may conform to the space between the stack of bottles and the panel. In different embodiments, any or all of the aforementioned tensioning systems may be used independently or in combination with each other.

In embodiments of the invention, each panel (front, rear, left, right) is provided with at least one engagement device for securing the panel to an adjacent panel. These engagement devices may be provided in the form of one or more a hooks, clamps, clips, hinges or other similar devices on one panel that engage with one or more openings or receptacles on an adjacent panel. In some embodiments of the invention, the engagement devices (e.g., hooks or latches) may be provided on the outer surface of the panel along a left or right side, and the openings or receptacles on the adjacent panel may be provided on an adjacent side. For example, and without limitation, one or more hooks may be provided on the right sides of all panels, and receptacles for receiving the hooks may be provided on the left sides of all panels; in these embodiments, the right side of each panel is engaged with the left side of another panel, forming a rectangular enclosure. In some embodiments, the hooks may be provided on flexible straps that are mounted to the first panel. In these embodiments, the flexible strap may be stretched to allow the hook to engage a receptacle on an adjacent panel, which then pulls the adjacent panel firmly against the first panel, forming a corner. It is to be appreciated that other securing structures may be used to engage adjacent panels including latches, clamps, clips, or other hinged attachments.

In addition to the engagement devices for securing a panel to an adjacent panel, the sides of each panel may be provided with one or more male or female connecting members for engagement with complementary engagement members on a side of an adjacent panel, for alignment and reinforcement. In some embodiments, these alignment members may be provided on the right and left edges of the side panels may be provided with one or more female openings operable to receive one or more connecting male members of the front or back panels. The male/female alignment members may be provided in alternating, symmetrical, asymmetrical, or other suitable complementary arrangements.

Embodiments of the present invention provide load locking systems and methods (e.g., alignment systems and methods) that may be operable to engage an assembled container with one or more adjacent assembled containers. The load locking embodiments include male protrusions (e.g., male receptacles) and/or female cavities (e.g., female receptacles) positioned on the exterior surfaces of one or more of the front, back, left and/or right side panels. In seme embodiments, the positions of the male and female receptacles may be alternated. In some embodiments, the receptacles may be provided under the bottommost viewing windows on a panel's exterior surface. In some embodiments, the receptacles may (also) be provided on the pallet base. The receptacles enable assembled containers to interlock together, which provides stability and eliminates the need for airbags between each container. In these embodiments, the assembled containers may engage with another container on any exterior side. The protrusions and cavities may have complementary geometries that allow the containers to align uniformly, forming a string or array of containers. In some embodiment, the male protrusions may have a tapering cross-section that allows the protrusion to align with the corresponding female cavity.

The panels and base pallet may be manufactured from any suitable durable material including without limitation rigid plastic, wood (e.g., debarked wood), recycled plastics, and heat-treated materials. The damping members should be made from a flexible and/or slightly deformable material, such as without limitation foam, rubber, silica, silicone, or other similar materials. The viewing windows may be open, or they may be made from a transparent or semi-transparent material such as, without limitation acrylic, polycarbonate, polyethylene terephthalate, amorphous copolyester (PETG), PVC, Polyethylene, or like materials.

In one exemplary embodiment, the invention takes the form of a bulk glass containment system formed from a set of interconnectable weatherproof panels, a pallet base and a lid that can be configured to define a boxlike containment structure over and around a volume of cargo. In this embodiment, the four panels may include: left-right side panels, front-back side panels, plus a bottom pallet base and a top lid. In this embodiment, each panel may have three half round protuberances located on the bottom of the panel that enter into a matching set of receptacles on the inner edge of the pallet base. The front and rear panels may have metal rods located at the top corners which slide into holes which are located in the top corners of the right and left panels. The rods and holes may be magnetically attracted to each other. The front and back panels may have a protuberance which is half way down from the metal rods on the front and back panels and slides into receptacles in the right and left panels when assembled. Each panel may be provided with multiple hooks along an edge that attach to an edge of the next corresponding panel. The lid may have protuberances that go into receptacles that are located on the top of each panel. The panels may be interconnected via manual latching hooks, to define a square or rectangular perimeter around the volume of cargo. A top lid may overlay the perimeter panels to fully enclose the cargo. In these embodiments, the four stabilizing panels may have a protruding rib that is built into each panel. These ribs may be provided between each row of viewing holes built into the panels and are designed to butt up against the cargo for a tight fit when all panels are assembled around the cargo. The ribs can be molded into the panel or made of a different softer material can by attached after the panel has been made. In these embodiments, the pallet base may have a series of holes from the front panel to the back panel to accommodate used panels that need to be shipped back to the factory for re-use. A load locking system incorporating a series of oval receptacles and protuberances may be integrated into the panels, sometimes at the bottom. This enables the units to interlock, eliminating the need for airbags during shipment. In some embodiments, the receptacles may be located on the bottom front and left and the protuberances may be located on the bottom right and back giving a single unit the ability to lock side to side and front to back.

It is also to be appreciated that although the male and female connecting members are illustrated as oval holes and protrusions, that they may be of any suitable cooperating shape including round, square, rectangular, hexagonal, octagonal or any other multi-sided shape.

In the interior view of the embodiment of FIG. 2, a plurality of male connecting members 1231 may be provided on pallet edge surface 1200P operable to nest into complimentary female channels 1130 of the pallet base 1100. (It is to be appreciated that in alternative embodiments, some or all of these male/female members may be swapped.) Stability ribs 1205 may be positioned at various locations along the interior surface of panel 1200 in order to touch and provide dampening to the bottles inside. In this illustrated embodiment they are located between the viewing windows 1210. In the embodiment illustrated in FIG. 2, connecting rods 1235 are positioned at top corners of panel 1200 (e.g., at the junction of 1200A and 1200T, or junction 1200B and 1200T). Rods 1235 are positioned perpendicular to the interior surface and may be operable to nest into openings 1335 of the right and left side panels 1300B, 1300A. This engagement is illustrated in FIG. 3.

FIGS. 3 and 4 provide side views of the pallet panel system 1000, more specifically a front view (exterior surface) of a side panel 1300 (e.g., a right side or left side) according to an embodiment of the present invention. The side panel 1300 may be sandwiched between the front and back panels 1200, top panel 1700, and the pallet base 1100 as shown in FIG. 3. The side panels 1300 may have a pallet interfacing surface 1300P, a panel top surface 1300T, and two side surfaces 1300A, 1300B. On the front surface of panel 1300, there may be a plurality viewing windows 1310 distributed laterally, allowing a user to view the parcel's contents inside the pallet system 1000. It is to be appreciated that although many rows of many windows 1310 are illustrated in FIGS. 3 and 4, in other embodiments fewer, larger, or smaller windows may be provided; or they may be provided in different patterns; or no windows may be provided at all. The side panels 1300 may be independently aligned with the pallet base 1100 with the connectors 1331 nesting into a channel on the pallet base 1100.

FIG. 5 shows a profile view of the side surface 1200A of the illustrated embodiments of the front/rear panel 1200, and FIG. 6 shows a profile view of the side surface 1300B of the illustrated side panels 1300. The two illustrated panels 1200, 1300 are operable to align with the pallet base 1100 such that the male connecting members 1231, 1331 nest into the complementary pallet base channels 1130 (see FIG. 11). The connecting member (rod) 1235 is slid into the connecting channel (slot) 1335 on the side surface 1300B of the side panels 1300. In some embodiments (not shown), rod 1235 may be magnetic, and slot 1335 may be made of metal for attraction; in other embodiments (not shown), rod 1235 may be of metal, and slot 1335 may be attractively magnetic. In the illustrated embodiment of FIGS. 5 and 6, magnetic members 1336 are provided which engage metal members around the connecting member 1235 to magnetically secure the panels together.

The exemplary front panel illustrated in FIG. 5 may include a connecting member 1225 that may be operable to engage a receiving channel 1325 on the side 1300B of side panel 1300. The connecting member 1225 may be positioned on the horizontal axis on the front panel's interior surface and may bulge out of the surface, and on the side panel's side surface 1300B and the horizontal axis, there may be a receiving channel 1325 that may be operable to receive the connecting member 1225 and align the panels before. (It is to be appreciated that in alternative embodiments, male/female members 1225, 1325 may be swapped.) The receiving channel 1325 and connecting members 1225 may have complementary geometries suited to align each panel with the adjacent panel. The geometries may be substantially curved, triangular, rectangular but may be substantially smooth to promote alignment without excessive force applied to a panel 1300, 1200 for alignment.

Referring to FIG. 5, it is seen that a plurality of stability ribs 1205 may be provided on an interior surface of panel 1200, operable to interface with fragile containers 1600 (e.g., glass bottles, etc.). Referring to FIG. 6, it is seen that a plurality of stability ribs 1305 may be provided on an interior surface of panel 1300, operable to interface with fragile containers 1600 (e.g., glass bottles, etc.). The ribs may be provided between the viewing windows 1310 as shown in FIG. 4 with the dotted lines 1305. The ribs 1305 may be positioned such that the ribbing is aligned with each bottle's labeling in a stack of bottles 1600. Ribs 1205 and 1305 may have a dampening characteristic and a geometry equal to the geometry of the object or glass bottle.

The panels in the illustrated embodiment are designed to be attached to adjacent panels. For example, latch 1215 of a front panel 1200 may hook into a receiver 1320 of a side panel 1300, and latch 1315 of a side panel 1300 may hook into a receiver 1220 of a rear panel 1200 (see FIGS. 9 and 12). When joined, in some embodiments the panels may form a substantially square perimeter, in other embodiments the perimeter may be substantially rectangular. In other embodiments, the hooks 1315 may be replaced with a hook and pawl mechanism (e.g., ratch), and the system may be secured together by increasing the tension of the straps and the panels around the four corners of the exterior surface.

FIG. 9 provides an exploded view of exemplary embodiments of front panels 1200 and side panels 1300. The illustrated side panels 1300 may first secure the male connecting members 1331 to the complementary channel 1130 of the pallet base 1100. The side panels 1300 may be positioned such that the front and rear panels 1200 may be slid into position with the connecting members 1231 nesting into the complementary channel 1130 of the pallet base 1100, and may enable the connecting rods 1235 to nest into the connecting rod location 1335 on the side surface 13006. The magnetic interaction between 1235 and 1335 (or members 1336) may hold the front and rear panels 1200 in place against side panels 1300 while a user secures the perimeter of the panels. The panels may be fastened together with the hooks 1215 that are engaged with receivers 1320.

In some embodiments, the connecting rod location 1335 may be a slot operable to accommodate a rotation of the front panel 1200 about the complementary channel 1130. The pallet base 1100 may be operable to provide a base for receiving a stack of bottles 1600 and may have thereon the top surface a plurality of receiving channels 1130 operable to receive the connecting members 1231, 1331 of the exterior panels 1200, 1300. An exemplary top-down view of the pallet base 1100 is shown in FIG. 11.

Once the panels are attached to each other, the container may be sealed with a lid 1700, an exemplary embodiment of which is shown in FIG. 10. Male connecting members 1730 on the lid are operable to engage with the top surface channels 1330 and 1230 of the perimeter panels 1200 and 1300. This may seal the panel system 1000. In some embodiments, the interior surface of the container lid 1700 may also include a magnetic strip (not shown) aligned with the perimeter edge of the lid. In such embodiments, the top surface 1200T, 1300T may have a plurality of magnets therebetween the channels 1330, 1230, the channels may guide the lid into position, and the magnets may secure the lid in place and seal the container. In other embodiments, male protrusions may be provided on upper surfaces 1200T and 1300T for engagement with openings 1730. (It is to be appreciated that in alternative embodiments, some or all of these male/female members may be swapped.)

FIG. 7 provides an exemplary top view of front or rear panel 1200 including top surface 1200T; and FIG. 8 provides an exemplary top view of side panels 1300T. Embodiments of the invention may provide on the interior of each panel a dampening structure (e.g., tensioning system, ribbing) 1205, 1305 with a geometry that may be complementary to the exterior surface of a glass bottle and may contact the bottle (not shown). The ribbing 1205, 1305 may be operable to apply tension to the bottles and dampen the vibrations produced from transportation. The tension system (e.g., ribbing) 1205, 1305 may be integrated into the interior surface of the perimeter panels and may be manufactured from durable foam such as polyethylene foam, high-density rigid foam, and EVA foam as examples. In other embodiments, the tension system may be a plurality of tension bands molded into the inside of the panel manufactured from a plastic or nylon material that has a geometry operable to provide a dampening resistance such as a leaf spring (not shown). In such embodiments, the leaf springs would replace the ribbing 1205, 1305 locations of the present invention and may be removably attached to the interior surface of the panel with a fastener. In yet other embodiments, the tension system may include a plurality of connected air bladders positioned in place of the ribbing 1205, 1305 on the panels interior surface inline with the bottle's label height in the stack (not shown). The air bladders may be deflated prior to assembly of the container 1000. In such embodiments, once the perimeter panels are connected, the air bladders may be inflated and may have an inflated geometry that is substantially elongated or may conform to the space between the stack and the panel. A combination of the aforementioned tensioning systems may be used in combination. The male channels 1240 and 1340 are shown to have a substantially convex outer protrusion that may be operable to nest into the female channels 1240A, 1340A and are staggered to lead on one edge.

The panel frame 1200 may be manufactured of wood (e.g., debarked wood), recycled plastics, and heat-treated materials. The stability ribs 1205 may be constructed of foam material, rubber material, silica silicone, or maybe of a cardboard composite construction, materials typically used in the transportation of fragile containers. The viewing windows 1210 may be manufactured of a transparent or semi-transparent material such as, but not limiting, acrylic, polycarbonate, polyethylene terephthalate, amorphous copolyster (PETG), PVC, Polyethylene, or like materials, having mechanical properties allowing for deflection and absorption of vibrations, and not likely to fracture.

Embodiments of the panel system of the present invention may be assembled by one or more people. The pallet base 1100 may receive a palletized stack of containers (e.g. glass bottles) 1600, where a layer of bottles is uniformly positioned in an array or matrix, and a slip sheet (e.g., cardboard sheet, plastic sheet) is placed on top of the layer of bottles. Another layer of bottles is placed uniformly on top of the sheet and a sheet is placed on top. The process is repeated for subsequent layers of bottles until a palletized stack 1600 is formed. A stack may be formed on top of the pallet base 1100 or may be rolled on top of the pallet base 1100. Once the stack of bottles 1600 is centered on the pallet 1100, an optional frame 1500 (a bottle lid) may be positioned on top of the bottles. An exemplary top-down view of the frame 1500 is provided in FIG. 11A. The frame 1500 may have a plurality of holes 1505 matching the position of each of the bottles in the topmost layer of the stack 1600 and may have a perimeter that is less than the interior perimeter of the panels 1200, 1300 when assembled. The frame holes 1505 may have a diameter equal to the diameter at a location at the neck of the bottle.

Two side panels 1300 may be placed on opposite sides of the stack of bottles 1600, and the side panels are secured to the pallet base. Then front and rear panels 1200 may be aligned with pallet base 1100 and may sandwich the two side panels 1300 in place. To secure the perimeter of the container, the strap and hooks 1215, 1315 are fastened to an adjacent panel's receiver hole 1320, 1220, and the lid 1700 is placed on top of the panel perimeter, forming a container. In some embodiments, the frame 1500 may be of the clamshell type, where the frame may be formed to provide a surface with a plurality of concavities having a substantially complementary geometry to the top lip of a glass bottle. In another embodiment, the stack of glass bottles 1600 may be wrapped with a thin plastic wrapping to provide a uniform structure for the bottles. FIG. 12 provides an exemplary exploded view of the pallet container 1000.

The container pallet panel system 1000 may interlink with additional containers 1000 and may combine to ship as a single array. An e view of a first container 1000A and second container 1000B is provided in FIG. 13. On the exterior surface of all the panels, there may be an alignment mechanism operable to snuggly configure adjacent pallet panel containers 1000 to align with each other for mass transportation and interlocking with each other. The alignment mechanism provides a system for aligning the containers 1000 and eliminating the need for a dampening mechanism (e.g., airbags, foam) between containers. When two or more containers 1000 are positioned adjacent to each other and locked together (FIGS. 14A-B), a string or array of container units may be formed which may operate as a single solid load, preventing the palletized stacks of bottles from toppling. In some of these embodiments, the surface side panel, 1300 of the first container 1000A, may provide male protrusions 1340 that may nest into the female cavities 1340A of the second container 1000B. Similarly, front panel channels 1240 may nest into corresponding channels 1240A when aligned with an adjacent container 1000. (It is to be appreciated that in alternative embodiments, some or all of these male/female members may be swapped.)

In some embodiments once the containers 1000A, 1000B are interlinked, the straps of a parallel panel may be strapped to the adjacent panel's receiver hole. For example, 1215 of the front panel of the first container 1000A may hook into the receiver 1220 of the second container 1000B front panel, as shown in FIG. 14. The advantage of interlinking the containers together prevents the stack of bottles from toppling over, saves space, and eliminates additional airbags for dampening.

In some embodiments, the alignment mechanism may include alternating male protrusions 1240 and female cavities 1240A that have complementary geometries. For example, the male protrusion 1240 may extrude from the exterior surface of the front panel 1200 and have a centroid equidistant from the pallet surface 1200P and the side surface 1200A, and the female cavity 1240A may have a centroid with an equidistance from the side surface 1200B and the pallet surface 1200P. In some embodiments the outer male protrusion 1240 and female cavity 1240A may alternate; in other embodiments they may be all male on one side and all female on the other side. It is to be appreciated that other arrangements of male and female connectors may also be used. The front and rear panel 1200 channels may be A-symmetrical related when the container is assembled, and the front surface channel 1240 may nest into the rear channel 1240A when aligned with an adjacent container 1000. Alike the front and rear surface 1200, the side panels 1300 may have an outer male protrusion 1340 and outer female cavity 1340A and therebetween may have a series of alternating female cavities 1340A and male protrusion 1340. The male protrusions 1240, 1340 may have a surface geometry such as a triangular wedge shape, drafted protrusion, or a substantially convex outer protrusion that are operable to nest into the female cavities 1240A, 13040A which have a geometry that is complementary to the male and removed from the surface of the panels. In some embodiments, the protrusion and cavity 1240/1240A, and 1340/1340A may have a sinusoidal surface that is fixed to the outer panels exterior surface. The male protrusion 1240/1340 may be removably attached to the outer surface with a fastener (e.g., rivet, screw, welded, etc.), and the female channel may be a material that is removed from the outer surface or may be attached to the outer surface with a fastener.

Although the embodiments described and illustrated depict certain engagement devices as male protrusions which engage with corresponding female receptacles, it is to be appreciated that any or all of these devices may be exchanged, swapping the male engagement devices for female ones, and vice versa. For example, and without limitation, female connecting channels 1230 and male connectors 1730 may be swapped, such that channels 1230 are male and connectors 1730 are female. It is also to be appreciated that although the male and female connecting members are shown as oval holes and protrusions in the illustrations herein, that in other embodiments, some or all of these complementary members may be of any suitable cooperating shape including round, square, rectangular, hexagonal, octagonal or any other multi-sided shape

The present invention provides a pallet panel system operable to enclose a palletized stack of glass bottles and is able to provide a boundary to protect the bottles from toppling, and eliminates plastic wrapping for stabilizing the stack of glass bottles.
