Definitions

  • This invention relates to a stackable and nestable container of the type that has numerous applications in manufacturing and related shipping and commerce.
  • This type of container is frequently used to ship parts and supplies between part and component suppliers and factories where the parts and components are incorporated into assembled products. When being shipped with contents, they are typically stacked on top of each other. To reduce the cost of shipping, this type of container is repeatedly reused, so it must be shipped back to the source, usually empty, for refilling and reshipping. For this reason, the containers are made with a side wall draft angle sufficient to permit the containers to be nested into each other when empty, a practice which dramatically increases the number of empty containers that can be accommodated in a given space.
  • the invention of this application provides a container that maximizes the usable volume of the container.
  • a stackable and nestable container having a bottom, opposed first and second end walls and opposed first and second side walls extending upwardly from the bottom and collectively defining an open top.
  • a first bale is mounted on, and extends between the first and second side walls proximate the first end wall and is movable between a stacking position extending into the open top of the container and a nesting position resting on a top edge of the first end wall.
  • a second bale is mounted on, and extends between the first and second side walls proximate the second end wall and is movable between a stacking position extending into the open top of the container and a nesting position resting on a top edge of the second end wall.
  • a first bale-receiving channel is formed in the bottom of the container, extending between the first and second side walls directly below the stacking position of the first bale, and sized and shaped to receive the first bale of a like container when in the stacking position to define a stack of containers.
  • a second bale-receiving channel is formed in the bottom of the container, extending between the first and second side walls directly below the stacking position of the second bale, and sized and shaped to receive the second bale of a like container when in the stacking position to define a stack of containers.
  • the first and second bales each include at least one outwardly-projecting tab for restricting lateral movement of a stacked like container by providing a stopping surface for first and second side walls of the like container.
  • the first and second bale-receiving channels define respective complementary first and second ridges on the bottom of the container, extending upwardly into the container.
  • the first and second side walls include recessed pockets in which respective first and second bales are mounted on pivots for pivotal movement between the stacking and nesting positions.
  • the recessed pockets each include a base on which the respective bale rests in the stacking position.
  • the first and second bales each include a radially-outwardly projecting support tab for supporting the respective bale on the container in the nesting position.
  • the first and second end walls each include first and second recessed pockets in which respective first and second bales are received when the bales are in the nesting position.
  • the first and second bales are cylindrical and the first and second channels are semi-cylindrical.
  • the first and second bales each include a pair of radially-outwardly projecting tabs for restricting the lateral movement of a like stacked container by providing stopping surfaces for the first and second side walls of the like container.
  • a stackable and nestable container includes surface elements on the first and second bales and surface elements on the first and second channels that are positioned to align and mate with the surface elements of the respective first and second bales of a like container when the container is in the stacking position.
  • the surface elements include a plurality of parallel, spaced-apart grooves that are perpendicular to a longitudinal axis of the respective bales and channels.
  • the surface elements include a plurality of parallel, spaced-apart, integrally-formed grooves that are perpendicular to a longitudinal axis of the respective bales and channels.
  • a stackable and nestable container having a bottom, opposed first and second end walls and opposed first and second side walls extending upwardly from the bottom and collectively defining an open top.
  • a first bale is mounted on and extends between the first and second side walls proximate the first end wall and is movable between a stacking position extending into the open top of the container and a nesting position resting on a top edge of the first end wall.
  • a second bale is mounted on and extends between the first and second side walls proximate the second end wall and is movable between a stacking position extending into the open top of the container and a nesting position resting on a top edge of the second end wall.
  • Recessed pockets are provided in which the respective first and second bales are mounted for movement between the stacking and nesting positions and including a base on which the respective bales rest in the stacking position.
  • a first channel is formed in the bottom of the container and extends between the first and second side walls to receive a first bale of a like container when in the stacking position to define a stack of containers.
  • a second channel is formed in the bottom of the container and extends between the first and second side walls to receive the second bale of a like container when in the stacking position to define a stack of containers.
  • the first and second bale-receiving channels define respective complementary first and second ridges on the bottom of the container, extending upwardly into the container.
  • the surface elements comprise a plurality of parallel, spaced-apart, integrally-formed grooves that are perpendicular to a longitudinal axis of the respective bales and channels.
  • the first and second bales are pivotally mounted for movement between the stacking and nesting positions.
  • first and second channels and first and second ridges are integrally formed in the bottom of the container and are opposed surfaces of first and second respective concave and convex structures.
  • FIG. 1 is a perspective view of a container according to one preferred embodiment of the invention in the nesting configuration
  • FIG. 2 is a perspective view of two like containers according to FIG. 1 with the upper container nested into the lower container;
  • FIG. 3 is a perspective view of a container according to one preferred embodiment of the invention in the stacking configuration
  • FIG. 4 is a perspective view of two of the containers of FIG. 3 in the stacking configuration
  • FIG. 5 is a bottom plan view of the container showing the bottom of the container and the channels formed into the exterior wall of the container bottom;
  • FIG. 6 is a fragmentary perspective view showing one of the bales in the stacking position
  • FIG. 7 is a fragmentary perspective view of one of the bales in the nesting position.
  • FIG. 8 is a fragmentary perspective view of one of the bales in an intermediate position between the nesting position and the stacking position.
  • a container 10 is shown and includes a bottom 12 , opposed first and second end walls 14 , 16 and opposed first and second side walls 18 , 20 .
  • the end walls 14 , 16 and side walls 18 , 20 extend upwardly at diverging draft angles from the bottom 12 to collectively form an open top. While the end walls 14 , 16 and side walls 18 , 20 are shown as planar surfaces, in many instances the walls may be provided with stiffening ribs and recesses and other features that do not form part of this invention.
  • the second end wall 16 and the second side wall 20 include respective hand holds 22 , 24 .
  • the container 10 and its components maybe manufactured by any suitable fabrication process, such as molding and maybe fabricated from any suitable plastic, resin or other material.
  • Bales 30 , 32 are each formed of cylindrical bars that are mounted on respective side walls 18 , 20 .
  • Bale 30 is mounted proximate the end wall 14 on arms 34 , 36 that pivot on pivot pins 38 , 40 .
  • the arms 34 , 36 pivot in recessed pockets 42 , 44 integrally molded into the container 10 .

  • bales 30 and 32 extend along the length of and rest on the top rim of the end walls 14 and 16 , respectively, when in the nested position. Because the bales 30 and 32 are supported along their entire length, they are protected against downward deformation while in the nested position. Bales 30 and 32 also include pivot pins 38 , 40 , 50 and 52 protruding from arms 36 , 38 , 46 and 48 that are press-fitted into recessed pockets 42 , 44 , 54 and 56 , so that the outer walls of the pockets 42 , 44 , 54 and 56 restrict side-to-side motion of the bales 30 and 32 in both the stacked and nested positions, and while pivoting.
  • Support tabs 58 , 59 , 60 and 61 may be provided to support the bales 30 and 32 in the nested position. However, it is considered preferable for this support to be provided by the top rim of the end walls 14 and 16 , since support is provided along the entire length of the bales 30 , 32 rather than just on the ends.
  • Bales 30 , 32 include a respective pair of surface elements in the form of a series of spaced-apart grooves 62 , 64 and 66 , 68 .
  • the grooves 62 , 64 and 66 , 68 may be integrally-formed onto the bales 30 , 32 during a molding process or formed by an additional step, such as by stamping or cutting. While grooves 62 , 64 and 66 , 68 are shown, alternative surface elements, such as complementary touch fastener elements or grooves having different orientations may be used.
  • the container 10 is shown in the nesting position with the bales 30 , 32 resting on the top edge of the end walls 14 , 16 .
  • clearance is provided for a like container 10 to nest into container 10 , leaving a predetermined clearance between the underside of the bottom 12 of the like container 10 and the inner surface of the container 10 .
  • the bottom 12 includes first and second elongate semi-cylindrical ridges 70 , 72 that extend upwardly from the inner surface of the bottom 12 .
  • the ridges 70 , 72 form a top wall of first and second channels 74 , 76 molded into the underside of the bottom 12 .
  • the containers 10 are limited in lateral shifting by the support tabs 59 , 61 , 58 , 60 of the lower container 10 , which engages the lower edge of the side walls 18 and 20 .
  • the channels 74 , 76 are provided with respective grooves 80 , 82 and 84 , 86 that align and mate with the grooves 62 , 64 on the bale 30 and grooves 66 , 68 on bale 32 when in the stacking position.
  • the grooves 80 , 82 and 84 , 86 of the channels 74 , 76 may be integrally formed during a molding process or formed by an additional step, such as by stamping or cutting. While the grooves 80 , 82 and 84 , 86 are shown, alternative surface elements, such as complementary touch fastener elements or grooves having different orientations maybe used, as well.
  • the bales 30 , 32 of the lower container 10 reside in the channels 74 , 76 of the upper container 10 .
  • FIG. 5 illustrates the channels 74 , 76 from the underside of the container 10 and further illustrates the grooves 80 , 82 and 66 , 68 .
  • FIGS. 6, 7 and 8 show details of the bale 32 (like features of bale 30 not shown) and its positions in the stacking ( FIG. 6 ), nesting ( FIG. 7 ) and between the two positions ( FIG. 8 ),
  • the containers 10 are not nested deeply enough for the first and second ridges 70 , 72 of a container 10 to nest into the first and second channels 74 , 76 of a like container 10 into which the container 10 is nested.
  • other embodiments of the container maybe sized and structured to facilitate this function.
  • the disclosure of this application is of a container 10 that has a non-flat inner bottom surface. This provides the maximum usable internal volume for the exterior size of the container.
  • product that is flexible such as hoses, wire harnesses and many products with similar features, or for packing in which small, individual parts fill the volume of the container, raised ridges on the inner bottom surface of the container do not affect packing and the added volume can be effectively utilized.
