Description

TECHNICAL FIELD

This disclosure relates to packaging. More specifically, this disclosure relates to a reinforced box.

BACKGROUND

Many boxes are often formed from a single sheet of material, such as a box blank. The box blank can often be a rigid board material, such as corrugated cardboard. The structural strength can depend upon the strength of the material used. For example, using a stronger material for the box can increase a stacking strength of the box which is the amount of downward force that can be exerted on the box before the box fails. However, not all portions of the box contribute equally to the stacking strength of the box, and some panels may not require heavier material to maintain the stacking strength of the box. For example, a bottom panel of the box has little effect on the stacking strength of the box; however, side panels of the box demonstrate a large effect on the stacking strength of the box. Because many box designs are formed from a single sheet of material, the bottom panel is often also comprised of heavier material than necessary to provide the desired stacking strength of the box leading to increased material costs.

DETAILED DESCRIPTION

The present disclosure can be understood more readily by reference to the following detailed description, examples, drawings, and claims, and the previous and following description. However, before the present devices, systems, and/or methods are disclosed and described, it is to be understood that this disclosure is not limited to the specific devices, systems, and/or methods disclosed unless otherwise specified, and, as such, can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting.

The following description is provided as an enabling teaching of the present devices, systems, and/or methods in its best, currently known aspect. To this end, those skilled in the relevant art will recognize and appreciate that many changes can be made to the various aspects of the present devices, systems, and/or methods described herein, while still obtaining the beneficial results of the present disclosure. It will also be apparent that some of the desired benefits of the present disclosure can be obtained by selecting some of the features of the present disclosure without utilizing other features. Accordingly, those who work in the art will recognize that many modifications and adaptations to the present disclosure are possible and can even be desirable in certain circumstances and are a part of the present disclosure. Thus, the following description is provided as illustrative of the principles of the present disclosure and not in limitation thereof.

As used throughout, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “an element” can include two or more such elements unless the context indicates otherwise.

Ranges can be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, another aspect includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another aspect. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint.

For purposes of the current disclosure, a material property or dimension measuring about X or substantially X on a particular measurement scale measures within a range between X plus an industry-standard upper tolerance for the specified measurement and X minus an industry-standard lower tolerance for the specified measurement. Because tolerances can vary between different materials, processes and between different models, the tolerance for a particular measurement of a particular component can fall within a range of tolerances.

As used herein, the terms “optional” or “optionally” mean that the subsequently described event or circumstance can or cannot occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.

The word “or” as used herein means any one member of a particular list and also includes any combination of members of that list. Further, one should note that conditional language, such as, among others, “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain aspects include, while other aspects do not include, certain features, elements and/or steps. Thus, such conditional language is not generally intended to imply that features, elements and/or steps are in any way required for one or more particular aspects or that one or more particular aspects necessarily include logic for deciding, with or without user input or prompting, whether these features, elements and/or steps are included or are to be performed in any particular aspect.

Disclosed are components that can be used to perform the disclosed methods and systems. These and other components are disclosed herein, and it is understood that when combinations, subsets, interactions, groups, etc. of these components are disclosed that while specific reference of each various individual and collective combinations and permutation of these may not be explicitly disclosed, each is specifically contemplated and described herein, for all methods and systems. This applies to all aspects of this application including, but not limited to, steps in disclosed methods. Thus, if there are a variety of additional steps that can be performed it is understood that each of these additional steps can be performed with any specific aspect or combination of aspects of the disclosed methods.

Disclosed is a reinforced box and associated methods, systems, devices, and various apparatus. The reinforced box comprises a body board, a first end panel, and a second end panel. It would be understood by one of skill in the art that the disclosed reinforced box is described in but a few exemplary embodiments among many. No particular terminology or description should be considered limiting on the disclosure or the scope of any claims issuing therefrom.

FIG. 1 is a top perspective view of a reinforced box 100 in an open configuration in accordance with one aspect of the present disclosure. The reinforced box 100 can comprise a body board 110, a first end panel 150a, and a second end panel 150b.

The first end flap 180a can be positioned between the first side panel 112a and the first end fold line 190a, and the second end flap 182a can be positioned between the second side panel 112b and the second end fold line 192a.

A first top flap 114a can be hingedly attached to the top end 116a of the first side panel 112a by a first top flap hinge 118a. A second top flap 114b can be hingedly attached to the top end 116b of the second side panel 112b by a second top flap hinge 118b. Each top flap 114a,b can define a top flap end 170a,b, respectively, which can be disposed opposite from the respective top flap hinge 118a,b. Each of the top flap ends 170a,b can define a respective top notch 172a,b.

A first top end flap 157a can be hingedly attached to the top end 152a of the first end panel 150a by a first top flap hinge 155a. A second top end flap 157b can be hingedly attached to the top end 152b of the second end panel 150b by a second top flap hinge 155b. In the present aspect, the top end flaps 157a,b can be sized smaller than the top flaps 114a,b; however in other aspects, the top end flaps 157a,b can be equal to or larger in size than the top flaps 114a,b. As shown, the end fold lines 190a,192a can also extend across the first top end flap 157a.

To enclose the box cavity 102, the top end flaps 157a,b can be folded inwards to partially cover the box opening 103, and then the top flaps 114a,b can be folded inwards to fully enclose and cover the box opening 103. A first top notch 172a of the top notches 172a,b can be configured to engage and interlock with a second top notch 172b of the top notches 172a,b. With the top notches 172a,b interlocked, the top flaps 114a,b can be secured together in a closed configuration, as shown in FIG. 12.

FIG. 2 is a side view of the reinforced box 100 facing the second end panel 150b. Similar to the first end panel 150a of FIG. 1, the second end panel 150b can be attached to the body board 110 by attaching a second side flap 144c,d of the respective side panels 112a,b (shown in FIG. 1) to the outer surface 151b of the second end panel 150b. The second side flaps 144c,d can be hingedly attached to the respective side panels 112a,b (shown in FIG. 1) by second side flap hinges 143c,d. A first end flap 180b and a second end flap 182b can also be attached to the outer surface 151b of the second end panel 150b. The first end flap 180b can be disposed between the first side 156b of the second end panel 150b and a first end fold line 190b, and the second end flap 182b can be disposed between the second side 158b of the second end panel 150b and a second end fold line 192b.

Each of the side flaps 144a-d can respectively define a top edge 240a-d, a major edge 242a-d, and a minor edge 244a-d, as shown in FIG. 6. Each of the end flaps 180a,b,182a,b can respectively define outer edges 246a-d, middle edges 248a-d, and inner edges 250a-d, as shown in FIG. 6. In the present aspect, the minor edges 244a-d can align with the adjacent outer edges 246a-d, as shown by the minor edges 244c,d and outer edges 246c,d. In the present aspect, an end flap notch 270b can be defined between adjacent inner edges 250c,d, and an end flap notch 270a can be defined between adjacent inner edges 250a,b, as shown in FIG. 3. In the present aspect, the end fold lines 190b,192b can intersect the inner edges 250c,d, and spacing between the end fold lines 190b,192b can define a flat tip 254b of the end flap notch 270b. In other aspects, adjacent inner edges 250a-d can intersect to define V-shaped notches between the adjacent end flaps 180a,b,182a,b.

FIG. 3 is a bottom perspective view of the reinforced box 100 facing the first end panel 150a and a bottom panel 310 of the body board 110. The bottom panel 310 can further define and enclose the box cavity 103 (box cavity 103 shown in FIG. 1). The bottom panel 310 can define a first bottom side 312a and a second bottom side 312b which can be disposed opposite from the first bottom side 312a. The first side panel 112a (first side panel 112a shown in FIG. 1) can be hingedly attached to the first bottom side 312a by a first side hinge 314a, and the second side panel 112b (second side panel 112b shown in FIG. 1) can be hingedly attached to the second bottom side 312b by a second side hinge 314b.

The bottom panel 310 can define a first bottom end 350a and a second bottom end 350b, and the second bottom end 150b can be disposed opposite from the first bottom end 350a. The first bottom end 350a can be positioned adjacent to the first end panel 150a, and the second bottom end 350b can be positioned adjacent to the second end panel 150b (shown in FIG. 2). The first end flap 180a and the second end flap 182a can be attached to the first bottom end 350a by a first end flap hinge 380a and a second end flap hinge 382a, respectively. The flat tip 254a of the end flap notch 270a can be defined by a portion of the first bottom end 350a between the first end flap hinge 380a and the second end flap hinge 382b.

The end flap notches 270a,b and the end fold lines 190a,b,192a,b can cooperate to transition the box 100 from the open configuration shown in the present aspect to a collapsed configuration shown in FIG. 5. The respective end panels 150a,b can fold substantially in half along the respective end fold lines 190a,b,192a,b, and the end flap notches 270a,b can provide clearance between adjacent end flaps 180a,b,182a,b for collapsing the end panels 150a,b.

A first bottom corner 324a of the bottom panel 310 can be defined at an intersection of the first bottom end 350a and the first bottom side 312a. A second bottom corner 324b of the bottom panel 310 can be defined at an intersection of the first bottom end 350a and the second bottom side 312b.

A fourth bottom corner 324d can be defined at an intersection of the second bottom end 350b and the second bottom side 312b.

In the present aspect, the bottom panel 310 can define a plurality of fold lines configured to collapse the bottom panel 310 when reconfiguring the reinforced box 100 from the open configuration to the collapsed configuration. The fold lines of the bottom panel 310 can cooperate to collapse the bottom panel 310 to a truncated rectangular pyramidal shape, as shown in FIG. 5. The bottom panel 310 can define a center subpanel 320 disposed at a center of the bottom panel 310. The center subpanel 320 can define a first end fold line 318a, a second end fold line 318b, a first side fold line 316a, and a second side fold line 316b. The end fold lines 318a,b can be substantially parallel to the bottom ends 350a,b, and the side fold lines 316a,b can be substantially parallel to the bottom sides 312a,b.

A first fold line corner 322a can be defined at an intersection of the first end fold line 318a and the first side fold line 316a. A second fold line corner 322b can be defined at an intersection of the first end fold line 318a and the second side fold line 316b. A third fold line corner 322c can be defined at an intersection of the second end fold line 318b and the first side fold line 316a. A fourth fold line corner 322d can be defined at an intersection of the second end fold line 318b and the second side fold line 316b.

A first corner fold line 342a can extend between the first fold line corner 322a and the first bottom corner 324a. A second corner fold line 342b can extend between the second fold line corner 322b and the second bottom corner 324b. A third corner fold line 342c can extend between the third fold line corner 322c and the third bottom corner 324c. A fourth corner fold line 342d can extend between the fourth fold line corner 322d and the fourth bottom corner 324d.

The bottom panel 310 can define first end fold lines 390a,b and second end fold lines 392a,b which can respectively align with the first end fold lines 190a,b and the second end fold lines 392a,b of the end panels 150a,b. The end fold lines 390a,392a can extend between the first bottom end 350a and the first end fold line 318a, and the end fold lines 390b,392b can extend between the second bottom end 350b and the second end fold line 318b.

A first plurality of fold lines 340a can extend from the first bottom corner 324a to the first end fold line 390a. The first plurality of fold lines 340a can be defined between the first corner fold line 342a and the first bottom end 350a. A second plurality of fold lines 340b can extend from the second bottom corner 324b to the second end fold line 392a. The second plurality of fold lines 340b can be defined between the second corner fold line 342b and the first bottom end 350a. A third plurality of fold lines 340c can extend from the third bottom corner 324c to the first end fold line 390b. The third plurality of fold lines 340c can be defined between the third corner fold line 342c and the second bottom end 350b. A fourth plurality of fold lines 340d can extend from the fourth bottom corner 324d to the second end fold line 392b. The fourth plurality of fold lines 340d can be defined between the fourth corner fold line 342d and the second bottom end 350b.

FIG. 4 is a perspective side view facing the first end panel 150a of the reinforced box 100 showing the reinforced box 100 in a partially collapsed configuration. As shown, the first end panel 150a can fold about the end fold lines 190a,192a, and the side flaps 144a,b can fold about the first side flap hinges 143a,b, respectively to bring the side panels 112a,b towards one another. By incorporating two end fold lines 190a,192a, the first end panel 150a can more easily fold completely or nearly in half because the angular deflection is spread between the two end fold lines 190a,192a, thereby reducing strain on each end fold line 190a,192a by a factor of two. For example and without limitation, in an aspect of the first end panel 150a defining a single end fold line, the single end fold line can be deflected approximately 180° when folding the first end panel 150a completely in half. In the present aspect, each of the end fold lines 190a,192a can be deflected approximately 90° when folding the first end panel 150a completely in half, thereby decreasing strain on each end fold line 190a,192a and decreasing resistance when collapsing the reinforced box 100. In other aspects, however, the first end panel 150a may only define a single end fold line. In the aspect shown in FIG. 4, the side flaps 144a,b can optionally be untapered side flaps 144a,b with the major edges 242a-d being substantially parallel to one another and the respective sides 140a,b,142a,b of the side panels 112a,b.

FIG. 5 is a perspective view of the reinforced box 100 in the collapsed configuration. The reinforced box 100 can be further compressed by wrapping a band or strap around one or more reinforced boxes 100, such as for storage or shipping of the reinforced boxes. For example, in some aspects, the reinforced box 100 can be compressed until the first side flap 144a contacts the second side flap 144b (shown in FIG. 1), and the second side flap 144c (shown in FIG. 2) contacts the second side flap 144d (shown in FIG. 2). In the collapsed configuration, the end panels 150a,b can be folded, as shown by the first end panel 150a. The bottom panel 310 can be collapsed into the shape of a truncated rectangular pyramid. Pressing upon the center subpanel 320 (shown in FIG. 3) of the bottom panel 310 in the collapsed configuration, such as by pushing the reinforced box 100 against the ground, can force the reinforced box 100 to expand to the open configuration.

The side panels 112a,b can respectively define bottom ends 512a,b (512b shown in FIG. 6) which can be attached to the respective bottom side 312a,b by the respective side hinge 314a,b, as shown and described with respect to FIG. 6. FIG. 6 is a top view of the body board 110 of the reinforced box 100 of FIG. 1. The first end flaps 180a,b can be attached to the respective bottom ends 350a,b of the bottom panel 310 by the first end flap hinges 380a,b. The first end flap hinges 380a,b can extend along the respective bottom ends 350a,b between the first bottom side 312a and the respective first end fold lines 390a,b. The second end flaps 182a,b can be attached to the respective bottom ends 350a,b of the bottom panel 310 by the second end flap hinges 382a,b. The second end flap hinges 382a,b can extend along the respective bottom ends 350a,b between the second bottom side 312b and the respective second end fold lines 392a,b.

The first side hinge 314a can hingedly attach the bottom end 512a of the first side panel 112a to the first bottom side 312a of the bottom panel 310. The first top flap hinge 118a can hingedly attach the top end 116a of the first side panel 112a to a bottom end 616a of the first top flap 114a. The first top flap end 170a can be defined opposite from the bottom end 616a and the first top flap hinge 118a. The first top flap end 170a can define a first top portion 660a and a second top portion 662a, and the first top notch 172a can be disposed between the first top portion 660a and the second top portion 662a. The first top flap 114a can define a first side 690a proximate to the second side 142a of the first side panel 112a and a second side 692a proximate to the first side 140a of the first side panel 112a.

The first top portion 660a can define a first straight edge 670a, and the second top portion 662a can define a second straight edge 672a.
