Definitions
- the present invention pertains to a plastic container that is constructed to support the combined weight of additional like containers stacked on top of the container, and is also constructed to efficiently use a three dimensional space occupied by a stack of the containers and to resist relative movement between adjacent containers assembled together in a three dimensionally arrayed stack of the containers.
- pourable product containers for example plastic blow molded one gallon liquid containers used to transport liquid products such as milk and fruit juices, or pourable granular products such as salt or pet food from a product producer to a product retailer have for some time been associated with the problem of transporting the product containers efficiently.
- Efficient transport of product containers basically requires that as many containers as possible be fit into the smallest area for transporting.
- containers such as cardboard or paperboard boxes containing goods are typically arranged in a tight fit three dimensional array on a pallet surface to efficiently transport the boxes.
- a tight fit two dimensional array of boxes is arranged as a bottom layer of boxes on the pallet surface. Additional tight fit two dimensional arrayed layers of boxes are stacked on top of the bottom layer. This results in a three dimensional tight fit arrangement of boxes on the pallet that can be efficiently transported.
- the pourable product container of the present invention overcomes the disadvantages associated with plastic blow molded liquid containers by providing a plastic blow molded pourable product container with a structure that is sufficiently strong to support several like containers stacked on top of the container.
- the container of the present invention is provided with a novel construction that enables a plurality of the containers to be arranged in a tightly packed, space efficient two dimensionally arrayed layer.
- the container construction resists relative movement between adjacent containers in the two dimensionally arrayed layer of the containers and resists relative movement between adjacent containers in a stack of the containers.
- the pourable product container of the invention is a plastic blow molded one gallon container.
- the container has a general cubic configuration with a rectangular or square top surface, a rectangular or square bottom surface and four side surfaces that extend between the top surface and bottom surface.
- the top surface has a cylindrical neck that surrounds an opening to the interior of the container.
- a substantially flat surface area of the top surface surrounds the neck.
- the neck is centered in the top surface.
- the bottom surface has at least one cylindrical interior wall that is recessed into the bottom surface.
- the cylindrical interior wall surrounds a cavity that is centered in the bottom surface.
- a substantially flat surface area of the bottom surface surrounds the cavity.
- the cavity is dimensioned to receive the container neck of a lower container when the substantially flat bottom surface area of an upper container is positioned on top of the substantially flat top surface area of the lower container.
- the neck of the lower container fits into the cavity of the upper container and provides a connection between the stacked containers that allows for only limited relative side to side movement between the upper and lower containers.
- the other two side surfaces of the container are constructed with pluralities of convex rib surface sections.
- the convex rib surface sections have lengths that extend between the container top surface and bottom surface, and widths that are sequentially arranged across each of the two side surfaces.
- the lengths of the convex rib surface sections merge with the container top surface and bottom surface, and thereby form each of the other two side surfaces as corrugation reinforced structures between the container top surface and bottom surface.
- the convex rib surface sections are complementary to the concave groove surface sections, wherein the convex rib surface sections of one container fit into the concave groove surface sections of a second container.
- This enables a plurality of the containers to be arranged in a tightly packed, space efficient two dimensionally arrayed layer with the convex rib surface sections and the concave groove surface sections of adjacent containers engaging each other.
- This enables forming a tight fit two dimensional arrayed layer of the containers on a pallet that resists relative movement between adjacent containers and makes efficient use of the pallet surface.
- the concave groove surface sections and convex rib surface sections of each container in the two dimensionally arrayed layer of containers provide the bottom layer of containers with enhanced structural strength for supporting additional two dimensional arrayed layers of containers stacked on the bottom layer of containers. Furthermore, the necks of each of the containers in the two dimensionally arrayed lower layers engage in the cavities of each of the containers in the two dimensionally arrayed upper layers and limit relative movements between the stacked layers of containers.
- the plastic blow molded container of the invention described above has enhanced structural strength to support additional layers of like containers stacked on the container. Furthermore, the construction of the container described above resists relative movement between adjacent containers in a two dimensionally arrayed layer of containers and resists relative movement between containers stacked on each other.

Abstract
A plastic blow molded pourable product container is constructed to support the combined weight of additional like containers stacked on top of the container, and is also constructed to efficiently use a three dimensional space occupied by a stack of containers and to resist relative movement between adjacent containers assembled together in a three dimensionally arrayed stack of the containers.
Description
- This patent application is a Continuation-In-Part of patent application Ser. No. 13/422,265, which was filed on Mar. 16, 2012 and is currently pending.
- The present invention pertains to a plastic container that is constructed to support the combined weight of additional like containers stacked on top of the container, and is also constructed to efficiently use a three dimensional space occupied by a stack of the containers and to resist relative movement between adjacent containers assembled together in a three dimensionally arrayed stack of the containers.
- Pourable product containers, for example plastic blow molded one gallon liquid containers used to transport liquid products such as milk and fruit juices, or pourable granular products such as salt or pet food from a product producer to a product retailer have for some time been associated with the problem of transporting the product containers efficiently.
- Efficient transport of product containers basically requires that as many containers as possible be fit into the smallest area for transporting. For example, containers such as cardboard or paperboard boxes containing goods are typically arranged in a tight fit three dimensional array on a pallet surface to efficiently transport the boxes. A tight fit two dimensional array of boxes is arranged as a bottom layer of boxes on the pallet surface. Additional tight fit two dimensional arrayed layers of boxes are stacked on top of the bottom layer. This results in a three dimensional tight fit arrangement of boxes on the pallet that can be efficiently transported.
- With pourable product containers such as plastic blow molded gallon containers or bottles, it is not possible to fully employ the same technique of arranging a three dimensional stack of boxes on a pallet. Conventional plastic blow molded containers do not have a sufficient structural strength to support the weight of additional blow molded plastic containers, one on top of another.
- There is a need for a plastic blow molded one gallon container construction that is sufficiently structurally strong to support the combined weight of additional stacked containers while also efficiently using a three dimensional space occupied by a three dimensional array of the containers.
- The pourable product container of the present invention overcomes the disadvantages associated with plastic blow molded liquid containers by providing a plastic blow molded pourable product container with a structure that is sufficiently strong to support several like containers stacked on top of the container. In addition, the container of the present invention is provided with a novel construction that enables a plurality of the containers to be arranged in a tightly packed, space efficient two dimensionally arrayed layer. The container construction resists relative movement between adjacent containers in the two dimensionally arrayed layer of the containers and resists relative movement between adjacent containers in a stack of the containers.
- The pourable product container of the invention is a plastic blow molded one gallon container. However, the concepts of the invention can be employed in other sizes of plastic containers. The container has a general cubic configuration with a rectangular or square top surface, a rectangular or square bottom surface and four side surfaces that extend between the top surface and bottom surface.
- The top surface has a cylindrical neck that surrounds an opening to the interior of the container. A substantially flat surface area of the top surface surrounds the neck. The neck is centered in the top surface.
- The bottom surface has at least one cylindrical interior wall that is recessed into the bottom surface. The cylindrical interior wall surrounds a cavity that is centered in the bottom surface. A substantially flat surface area of the bottom surface surrounds the cavity. The cavity is dimensioned to receive the container neck of a lower container when the substantially flat bottom surface area of an upper container is positioned on top of the substantially flat top surface area of the lower container. The neck of the lower container fits into the cavity of the upper container and provides a connection between the stacked containers that allows for only limited relative side to side movement between the upper and lower containers.
- Two of the four side surfaces of the container are constructed with pluralities of concave groove surface sections. The concave groove surface sections have lengths that extend between the container top surface and bottom surface, and widths that are sequentially arranged across each of the two side surfaces of the container. The lengths of the groove surface sections merge with the container top surface and bottom surface, and thereby form each of the two side surfaces as corrugation reinforced structures between the container top surface and bottom surface.
- The other two side surfaces of the container are constructed with pluralities of convex rib surface sections. The convex rib surface sections have lengths that extend between the container top surface and bottom surface, and widths that are sequentially arranged across each of the two side surfaces. The lengths of the convex rib surface sections merge with the container top surface and bottom surface, and thereby form each of the other two side surfaces as corrugation reinforced structures between the container top surface and bottom surface.
- The convex rib surface sections are complementary to the concave groove surface sections, wherein the convex rib surface sections of one container fit into the concave groove surface sections of a second container. This enables a plurality of the containers to be arranged in a tightly packed, space efficient two dimensionally arrayed layer with the convex rib surface sections and the concave groove surface sections of adjacent containers engaging each other. This enables forming a tight fit two dimensional arrayed layer of the containers on a pallet that resists relative movement between adjacent containers and makes efficient use of the pallet surface. Additionally, the concave groove surface sections and convex rib surface sections of each container in the two dimensionally arrayed layer of containers provide the bottom layer of containers with enhanced structural strength for supporting additional two dimensional arrayed layers of containers stacked on the bottom layer of containers. Furthermore, the necks of each of the containers in the two dimensionally arrayed lower layers engage in the cavities of each of the containers in the two dimensionally arrayed upper layers and limit relative movements between the stacked layers of containers.
- The plastic blow molded container of the invention described above has enhanced structural strength to support additional layers of like containers stacked on the container. Furthermore, the construction of the container described above resists relative movement between adjacent containers in a two dimensionally arrayed layer of containers and resists relative movement between containers stacked on each other. Further features of the container of the invention are set forth in the following description of the drawing figures and in the detailed description of the invention.

FIGS. 1,2 and 3 show perspective views of opposite sides of thepourable product container 12 of the invention. In the embodiment of the container shown inFIGS. 1, 2 and 3 , thecontainer 12 is a plastic, blow molded one gallon bottle. The container orbottle 12 is constructed to contain one gallon of a liquid such as milk or juice, or contain granular products such as salt or pet food. In the illustrated embodiment, thecontainer 12 is constructed as a blow molded plastic container in order to construct the container as cost efficiently as possible. Other manufacturing techniques could be employed in constructing thecontainer 12, as well as other materials. However, because conventional plastic blow molded containers are not particularly structurally strong, the particular construction of thecontainer 12 to be described is well suited for enhancing the structural strength of a plastic blow molded container to enable several product filled containers to be arranged in a vertical stack with the bottom most container in the stack having sufficient structural strength to support the combined weight of the above product containers in the stack. - As seen in the drawing figures, the
container 12 has a general cubic configuration that is defined by the combination of the rectangular orsquare top surface 14, the rectangular orsquare bottom surface 16 and the rectangular or square fourside surfaces side surfaces container 12 and extend between and merge into thetop surface 14 and thebottom surface 16. The side surfaces 18 a, 18 b are mirror images of each other and therefore only one of the side surfaces 18 a will be described in detail. The side surfaces 22 a, 22 b are mirrored images of each other and therefore only one of thesurfaces 22 a will be described in detail. - The generally square configuration of the
top surface 14 is defined by four top corner surfaces 24 a, 24 b, 26 a, 26 b. The top corner surfaces 24 a, 24 b, 26 a, 26 b extend around and border thetop surface 14. The four top corner surfaces 24 a, 24 b, 26 a, 26 b extend across the tops of the respective side surfaces 18 a, 18 b, 22 a, 22 b and merge the side surfaces into thetop surface 14. As seen in the drawing figures, the top corner surfaces 24 a, 24 b, 26 a, 26 b are rounded surfaces that form a smooth transition between thetop surface 14 and the fourside surfaces top surface 14 has a substantiallyflat surface area 28 that is bounded by the four top corner surfaces 24 a, 24 b, 26 a, 26 b. Theflat surface area 28 surrounds cube-shapedwalls 34 that project upwardly from the center of theflat surface area 28. The cube-shapedwalls 34 extend upwardly from theflat surface area 28 and merge smoothly into a substantially flatsquare surface 36. Acylindrical container neck 38 extends upwardly from the center of thesquare surface 36. Theneck 38 surrounds an opening to the container interior. Acylindrical cap 40 is screw threaded onto theneck 38. Thecap 40 selectively closes and opens the opening to the container interior. Other equivalent types of closure devices could be used with thecontainer 12 in place of thecap 40. Additionally, in other embodiments the cube-shapedwalls 34 could be a cylindrical wall and thesquare surface 36 could be annular. - The
container bottom surface 16 also has a general square configuration defined by four bottom corner surfaces 42 a, 42 b, 44 a, 44 b that extend around and border thebottom surface 16. The bottom corner surfaces 42 a, 42 b, 44 a, 44 b extend across the bottoms of the respective side surfaces 18 a, 18 b, 22 a, 22 b and merge the side surfaces into thebottom surface 16. As seen in the drawing figures, the bottom corner surfaces 42 a, 42 b, 44 a, 44 b are rounded surfaces that smoothly transition the bottoms of the fourside surfaces bottom surface 16. The four bottom corner surfaces 42 a, 42 b, 44 a, 44 b surround and form a border around a substantiallyflat surface area 46 of thebottom surface 16. Cube-shapedinterior walls 48 are centered in theflat surface area 46 and extend into the container interior from theflat surface area 46. The interior cross section dimensions of theinterior walls 48 are slightly larger than the exterior cross section dimensions of the cube-shapedwalls 34 that project from theflat surface area 28 of thetop surface 14. Theinterior walls 48 extend to a substantially flatsquare surface 52. The area of thesquare surface 52 on thebottom surface 16 is slightly larger than the area of the flatsquare surface 36 on thetop surface 14. A cylindricalinterior wall 54 extends into the container interior from thesquare surface 52 on thebottom surface 16. The cylindricalinterior wall 54 is centered in thesquare surface 52 and extends into the container interior to a substantially flatcircular surface 56. The interior diameter dimension of the cylindricalinterior wall 54 is slightly larger than the exterior diameter dimension of thecap 40 and theneck 38 on the containertop surface 14. - With the cube-shaped
interior walls 48 on thebottom surface 16 dimensioned just slightly larger than the cube-shapedwalls 34 on thetop surface 14 and with the cylindricalinterior wall 54 dimensioned just slightly larger than thecontainer neck 38 and thecap 40, thebottom surface 16 of one container can be positioned on thetop surface 14 of a second container as shown inFIG. 9 with the cube-shapedwalls 34, neck 30 andcap 40 of the second container fitting easily inside the respective cube-shapedinterior walls 48 and cylindricalinterior wall 54 of the one container. With the bottomflat surface area 46 of the one container engaged and being supported on the topflat surface area 28 of the second container, the cube-shapedwalls 34, neck 30 andcap 40 of the bottom container allow only limited movement of the top container relative to the bottom container. In other embodiments, the cube-shapedinterior walls 48 could be cylindrical and thesquare surface 52 could be circular. - Two adjacent side surfaces 18 a, 18 b of the four side surfaces merge smoothly together at a rounded
side corner surface 62 that extends between thetop surface 14 andbottom surface 16. The top end of theside corner surface 62 merges smoothly into adjacent ends of thetop corner surface 24 a and thetop corner surface 24 b. The opposite, bottom end of theside corner surface 62 merges smoothly into adjacent ends of thebottom corner surface 42 a and of thebottom corner surface 42 b. As stated earlier and as best seen inFIG. 1 , the side surfaces 18 a, 18 b on opposite sides of thecorner surface 62 are mirror images of each other. Each of thesurfaces groove surface sections 64. The concavegroove surface sections 64 are substantially parallel and have lengths that extend between thetop surface 14 and thebottom surface 16 and have widths that are sequentially arranged completely across the twoside surfaces FIGS. 7 and 8 , each of the concavegroove surface sections 64 has a cross-section configuration that curves inwardly toward the interior of the container and has the appearance of a portion of a circle. This is what is meant by a “concave groove surface section”. The lengths of thegroove surface sections 64 merge smoothly into the top corner surfaces 24 a, 24 b and into the bottom corner surfaces 42 a, 42 b, and thereby form each of the side surfaces 18 a, 18 b as corrugation reinforced structures between thetop surface 14 and thebottom surface 16. As seen inFIG. 7 , the lengths and widths of thegroove surface sections 64 occupy a majority of the areas of the side surfaces 18 a, 18 b. Only narrow peaks orridges 66 formed where adjacentgroove surface sections 64 meet separate adjacent groove surface sections from each other. Like thegroove surface sections 64, the peaks orridges 66 are substantially parallel and extend along the lengths of thegroove surface sections 64 between thetop surface 14 andbottom surface 16. As can be seen inFIGS. 7 and 8 , the sequential and alternating arrangement of the concavegroove surface sections 64 and theridges 66 extending across a majority of the area of each side surface 18 a, 18 b has a cross-section configuration of a series of waves on a surface of water. The peaks orridges 66, like the concavegroove surface sections 64 function as corrugation reinforcement structures on the side surfaces 18 a, 18 b. -
Rectangular openings side surfaces openings side corner surface 62. The generallyrectangular openings container 12 between the twoopenings container 12 that is dimensioned to allow the fingers of a user's hand to easily pass through the passageway. Together theopenings handle 74 on theside corner surface 62 of the container. - The other two adjacent side surfaces 22 a, 22 b merge smoothly together at a rounded
side corner surface 76 between the two surfaces. A top end of theside corner surface 76 merges smoothly into adjacent ends of thetop corner surface 26 a and thetop corner surface 26 b. A bottom end of theside corner surface 76 merges smoothly into adjacent ends of thebottom corner surface 44 a and thebottom corner surface 44 b. - As stated earlier and as best seen in
FIG. 4 , the other twoside surfaces corner surface 76 are mirror images of each other. Each of the side surfaces 22 a, 22 b is formed with pluralities of convexrib surface sections 78. The convexrib surface sections 78 are substantially parallel and have lengths that extend between the containertop surface 14 andbottom surface 16, and widths that are sequentially arranged completely across the twoside surfaces FIGS. 7 and 8 , each of the convex rib surface sections has a cross-section configuration that curves outwardly away from the interior of the container and has the appearance of a portion of a circle. This is what is meant by a “convex surface section”. The top ends of each of therib surface sections 78 on the side surfaces 22 a, 22 b merge smoothly into the respective top corner surfaces 26 a, 26 b and thereby merge smoothly with theflat surface area 28 of thetop surface 14. The bottom ends of each of therib surface sections 78 on the side surfaces 22 a, 22 b merge smoothly into the respective bottom corner surfaces 44 a, 44 b and thereby merge smoothly into theflat surface area 46 of thebottom surface 16. The lengths of therib surface sections 78 form each of the twoside surfaces top surface 14 and thebottom surface 16. The lengths and widths of therib surface sections 78 occupy a majority of the areas of the side surfaces 22 a, 22 b. Only narrow slots orvalleys 82 formed where adjacentrib surface sections 78 meet separate adjacent rib surface sections from each other. Like therib surface sections 78, the slots orvalleys 82 are substantially parallel and extend along the lengths of therib surface sections 78 between thetop surface 14 and thebottom surface 16. As can be seen inFIGS. 7 and 8 , the sequential and alternating arrangement of the convexrib surface sections 78 and thevalleys 82 extending across a majority of the area of each side surface 22 a, 22 b has a cross-section configuration that is the inverse of the cross-section configuration of the sequential and alternating arrangement of the concavegroove surface sections 64 and theridges 66. The slots orvalleys 82, like therib surface sections 78 function as corrugation reinforcement structures on the side surfaces 22 a, 22 b. - As shown in
FIGS. 1-4 , the two adjacent side surfaces 18 a, 18 b and the two adjacent side surfaces 22 a, 22 b merge smoothly together at two additional rounded side corner surfaces 84, 86 that extend between thetop surface 14 and thebottom surface 16. The top end of theside corner surface 84 merges smoothly into adjacent ends of thetop corner surface 24 b and thetop corner surface 26 a. The opposite bottom end of theside corner surface 84 merges smoothly into adjacent ends of thebottom corner surface 42 b and thebottom corner surface 44 a. The top end of theside corner surface 86 merges smoothly into adjacent ends of thetop corner surface 24 a and thetop corner surface 26 b. The opposite bottom end of theside corner surface 86 merges smoothly into adjacent ends of thebottom corner surface 42 a and thebottom corner surface 44 b. - The convex
rib surface sections 78 are complementary to the concavegroove surface sections 64. The convexrib surface sections 78 of one container fit into the concavegroove surface sections 64 of a second container. This enables pluralities ofcontainers 12 to be arranged in a two dimensional array as shown inFIG. 12 with the convexrib surface sections 78 and the concavegroove surface sections 64 of adjacent containers engaging each other. Onecontainer 12 can be manually moved substantially horizontally toward anadjacent container 12 to engage the convexrib surface sections 78 and the concavegroove surface sections 64 of the adjacent containers. The adjacent containers and the engaging surface sections of the containers remain unattached to each other. This enables theadjacent containers 12 to be easily removed from the two dimensional array of containers when removing thecontainers 12 from a pallet by manually moving the adjacent containers horizontally away from each other. In this manner a tight fit two dimensional arranged layer ofcontainers 12 can be formed on a pallet surface with the engagement between the side surfaces 18 a, 18 b, 22 a, 22 b of adjacent containers resisting relative movement between the containers and also making efficient use of the surface area of the pallet. Additionally, the concavegroove surface sections 64 and convexrib surface sections 78 of the containers in the two dimensionally arranged layer of containers provide the bottom layer of containers with enhanced structural strength for supporting additional two dimensionally arrayed layers of containers stacked on the bottom layer of containers as shown inFIG. 13 . Furthermore, the necks of the two dimensionally arrayedcontainers 12 in the lower layers engage in the cavities of the upper layers of two dimensionally arranged layers of containers as shown inFIG. 9 and resist relative movement between the stacked layers of containers. - The plastic blow molded
container 12 of the invention described herein has enhanced structural strength to support additional layers of like containers stacked on the container. Furthermore, the construction of the container described herein resists relative movement between adjacent containers in a two dimensionally arranged layer of containers and resists relative movement between containers stacked on each other. - As various modifications could be made in the construction of the container of the invention herein described and illustrated without departing from the scope of the invention, it is intended that all matter contained in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative rather than limiting. Thus, the breadth and scope of the present invention should not be limited by any of the above described exemplary embodiments, but should be defined only in accordance with the following claims appended hereto and their equivalents.
