STACKING EFFICIENT DRY FLOW BIN

Abstract

The invention is directed to a stacking efficient dry flow bin. The bin can be configured in a nested configuration for transport and in an expanded configuration for use in holding and dispensing a flowable material. The bin is configured to stack with other like bins so that a stack three bins high will fit in the compartment of a standard shipping truck.

DETAILED DESCRIPTION

[0027] While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.

[0028] FIG. 1 shows a flowable material bin 10 in accordance with the present invention in a nested configuration and FIG. 2 shows the bin in an expanded configuration. The bin 10 includes a base portion 12 (visible in FIG. 2), an outer shell portion 14 and a top cap 16. The bin 10 is generally rectangular with each of the base portion 12 and the shell portion 14 having four side walls.

[0029] When nested, the outer shell 14 encloses and covers most of the base portion 12. The bin 10 can be transported (when empty) in this configuration. During use, the outer shell portion 14 is inverted and attached to an upper section of the base portion 12.

[0030] The bin 10 is particularly configured to allow one or more like bins 10 to stack one on top of the other when each bin 10 is in the nested configuration. In the present application, a like bin refers to an identical or substantially identical bin having the identical or substantially identical outward dimensions in a nested configuration and features which mate with other like bins. Three such bins 10 are shown stacked in FIG. 3.

[0031] The bins 10 are specifically designed so that they can be stacked three high in the nested configuration in 107 incheswhich is the useable interior height of a standard truck storage compartment. This allowed for the truck to carry up to sixty-six bins. Prior bins (such as those made in accordance with the '022 patent) did not stack as efficiently as the present bin 10, and could only stack two high in such trucks. Accordingly, the trucks could only transport up to forty-four of the previously known bins.

[0032] As shown in FIGS. 1 and 2, the base portion 12 includes a lower support portion 18. The lower support portion 18 is the only portion of the base visible when the bin 10 is in the nested configuration.

[0033] The bin 10 is configured to dispense a flowable material through an opening in the bottom of the base portion 12. FIGS. 4 and 5 show the bottom of the base portion 14.

[0034] The base portion 14 on its own is shown in FIGS. 6, 7 and 8. The base portion 12 includes four side walls 20 and an open top portion. The interior of the base portion 12 includes slanted bottom walls 22 which direct the flowable material to an opening 24 in the middle of the base portion 12.

[0035] FIG. 9 shows the outer shell portion 14 on its own. The shell portion 14 includes four side walls 26 and an open top and open bottom. As mentioned, the outer shell 14 surrounds and substantially encloses the base portion 12 when the bin is in a nested configuration (as shown in FIG. 1). The outer shell 14 is inverted (turned upside down) and attached to the top of the base portion 12 when used to hold a flowable material (as shown in FIG. 2). The outer shell 14 includes a first plurality of struts 28 extending across the top opening (in the nested configuration) from a first side wall to an opposing side wall. The outer shell 14 also includes a second plurality of struts 30 perpendicular to the first plurality of struts 28 extending across the opening from the other opposing side walls.

[0036] As shown in FIG. 9, each of the first plurality of struts 28 have a first brace 32 and a second brace 34 connected between a side wall and a portion of the strut 28 proximate the side wall. The braces 32, 34 help support each strut 28. While not shown with respect to any of the second plurality of struts 30, such struts 30 can also include one or both of the braces 32, 34.

[0037] The top cap 16 is shown in FIG. 10. The top cap 16 includes an upper surface having a plurality of upwardly extending ridges 36 around a periphery of the upper surface. A first set of the ridges 36 include an outer recess 38 and a second set does not include any recess. The first set of ridges includes one in each corner of the top cap 16 having an L-shape. Each of the corner ridges has two of the recesses 38. The bottom support 18 of the base portion 12 is designed to mate with structure on the top cap 16.

[0038] The top cap 16 also includes raised structure 40 in a central or middle portion of the support surface. A first channel 42 extends through the raised portion 40, a second channel 44 extends through the raised portion 40 perpendicular to the first channel 42. A center portion 46 extends upward where the first channel 42 meets the second channel 44.

[0039] As used herein, directional words or phrases (e.g., upward, top, bottom, right, etc.) are made with respect to the position of the invention as shown in the Figures and as commonly or typically positioned, and are not meant to limit the invention to such position(s).

[0040] Other features of the bin 10 are shown in the Figures.

[0041] Many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood within the scope of the appended claims the invention may be protected otherwise than as specifically described.
