LOCKING BOX

TECHNICAL FIELD
Field of Use

This disclosure relates to boxes. More specifically, this disclosure relates to folding boxes with a tamper-evident locking tab that can be formed from a blank.

Related Art

Boxes are commonly used to store food and other goods. Because boxes are usually discarded after use, especially for relatively inexpensive goods, boxes are typically made from relatively inexpensive materials. Given their low cost, typical boxes such as, for example and without limitation, those used to carry pizza or other food ordered for delivery to a customer location, have no ability to be locked or secured. Without some form of security, however, a delivery person or anyone else with access to the box can open the box and remove some or all of the goods without any evidence of tampering on the outside of the box. When the customer discovers the issue, the delivery person is typically gone.

DETAILED DESCRIPTION

The present disclosure can be understood more readily by reference to the following detailed description, examples, drawings, and claims, and their 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, 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 their 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 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 a quantity of one of a particular element can comprise two or more such elements unless the context indicates otherwise. In addition, any of the elements described herein can be a first such element, a second such element, and so forth (e.g., a first widget and a second widget, even if only a “widget” is referenced).

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 comprises 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” or “substantially,” 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 may or may not occur, and that the description comprises 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 comprises any combination of members of that list. The phrase “at least one of A and B” as used herein means “only A, only B, or both A and B”; while the phrase “one of A and B” means “A or B.”

To simplify the description of various elements disclosed herein, the conventions of “left,” “right,” “front,” “rear,” “top,” “bottom,” “upper,” “lower,” “inside,” “outside,” “inboard,” “outboard,” “horizontal,” and/or “vertical” may be referenced. Unless stated otherwise, “front” describes that end of a blank or an assembled box or any portion thereof nearest to a primary or initial point of opening; “rear” is that end of the blank or the assembled box or any portion thereof that is opposite or distal the front; “left” is that which is to the left of or facing left from a person facing towards the front; and “right” is that which is to the right of or facing right from that same person facing towards the front. “Horizontal” or “horizontal orientation” describes that which is in a plane extending from left to right and aligned with the horizon. “Vertical” or “vertical orientation” describes that which is in a plane that is angled at 90 degrees to the horizontal.

In one aspect, a locking device for a box and associated methods, systems, devices, and various apparatuses are disclosed herein. In one aspect, the locking device can comprise a locking tab. In one aspect, the locking device can comprise a panel defining a locking opening engagable or configured to engage with the locking tab.

As disclosed in the figures disclosing a blank 100, various line thicknesses and colors can indicate certain characteristics of the geometry. In some aspects, a thicker solid line can indicate the edge of a part; a thinner solid line can indicate a bend line; a dash line can indicate a hidden edge (and edge covered by other geometry), a perforated cut or connection, or a boundary or boundaries of a detail view; a dot-dash line can indicate material that is cut away and not shown for clarity, and a double dot-dash line can indicate a boundary or boundaries of separately claimable elements. Unless otherwise specified, a geometric center of any thicker lines determine the shape and position of the disclosed geometry. Any dimensions disclosed in the figures are exemplary only, and it is contemplated that the blank 100 and a box 1000 formed therefrom can be any shape and size. In some aspects, for example and without limitation, the box 1000 can be used for delivery of a food such as pizza or other consumer goods such as clothing. In other aspects, the box 1000 can enclose any goods needing to be shipped and/or stored in a protective container.

In some aspects, as shown, the bending tabs 288,298 can define a polygonal shape and, more specifically, a rectangular shape, including when considering the insertion tab baselines 387,397. In other aspects, either or both of the bending tabs 286,296 can define another shape. Adjacent ends such as the ends 381,383, the ends 383,382, the ends 382,384, the ends 384,381, the ends 391,393, the ends 393,392, the ends 392,394, and the ends 394,391 can intersect at corners of the bending tabs 288,298. As shown, a bending tab such as the bending tab 298 can define the locking opening 258.

The blank 100 can further define insertion tabs 336,338, which can extend from an end of a panel of the blank 100. More specifically, as shown, the insertion tabs 336,338 can extend from the second end 232 or from an insertion tab baseline 337 of the inside end panel 230.

The blank 100 can define openings, which can be sized to receive and capture or hold an insertion tab such as one or more of the insertion tabs 388,398 during assembly of the box 1000, the locking tab 252 during use and, more specifically, closure of the box 1000, and a finger of a user during use and, more specifically, opening of the box 1000. More specifically, the blank 100 can define an opening 326, which can be sized to receive the insertion tab 388 and the insertion tab 336; and an opening 328, which can be sized to receive the insertion tab 398 and the insertion tab 338. The blank 100 can define an opening 352, which can be sized to receive the locking tab 252 during use and, more specifically, closure of the box 1000. The blank 100 can define an opening 316, which can be sized to receive a finger of the user during use and, more specifically, opening of the box 1000.

In some aspects, as shown, any of the openings 318,326,328 can be an elongated hole. In some aspects, as shown, the opening 352 can define a rectangular shape. In some aspects, any of the openings 318,326,328,352 can define another shape. In some aspects, as shown, any of the openings 318,326,328,352 can extend from the inner surface 103 to the outer surface 104 (shown in FIG. 7) of the blank 100, i.e., through a full thickness of the blank 100. In some aspects, the openings 318,326,328 need not extend through a full thickness of the blank 100. In some aspects, any of the openings 318,326,328,352 can be aligned along or symmetrical about the longitudinal axis 101, the transverse axis 102, or one of the aforementioned ends of the aforementioned panels. In some aspects, an edge of the any of the openings 318,326,328,352 can be substantially aligned with an edge of one of the aforementioned panels. More specifically, an edge of the openings 326,238 closest to the first end 221 of the second end panel 220 can be substantially aligned or fully aligned with the first end 221. Similarly, edges of the opening 352 closest to the first end 341 and the second end 342 of the connecting panel 240 and corresponding ends of the second end panel 220 and the inside end panel 230 can be substantially aligned or fully aligned with the respective ends 341,342. As shown, an offset distance 301 between a particular common reference point 305 on the blank 100 or the assembled box 1000 and a center of the opening 352 can match or be equal to an offset distance 302 between the reference point 305 and the central axis 501 of the locking opening 258.

The blank 100 can define the connecting panel 240. The connecting panel 240 can extend from the second end panel 220 to the inside end panel 230. More specifically, as shown, the connecting panel 240 can extend from the second end 222 of the second end panel 220 to the first end 231 of the inside end panel 230. The connecting panel 240 can thereby be joined to each of second end panel 220 and the inside end panel 230. The connecting panel 240 can define a first end 341, a second end 342, a third end 343, and a fourth end 344. As shown, the second end 342 can be distal from the first end 341, and the fourth end 344 can be distal from the third end 343. In some aspects, as shown, the connecting panel 240 can define a rectangular or substantially rectangular shape and, in some aspects, a square shape. Adjacent ends such as the ends 341,343, the ends 343,342, the ends 342,344, and the ends 344,341, can intersect at corners of the connecting panel 240.

The connecting panel 240 can be sized such that a distance between the second end panel 220 and the inside end panel 230 in the assembled box 1000 is sufficient to receive the respective bending tab 288,298 on each side of the box 1000 and also the locking tab 252 when folded over as will be described below.

FIG. 4 is a detail view of the locking tab 252 of FIG. 2 taken from detail 4 of FIG. 2. In some aspects, the locking tab 252 can extend from and be joined to the first end panel 210. In some aspects, the locking tab 252 can extend from and be joined to the first main panel 110. In some aspects, a portion of the locking tab 252 can extend from and be joined to the first main panel 110 and a portion of the locking tab 252 can extend from and be joined to the first end panel 210. As shown, the locking tab 252 can be centered about and symmetrical about the central axis 401 of the locking tab 252.

The locking tab 252 can comprise a first tab subpanel 410, a second tab subpanel 420, and a third tab subpanel 430. The first tab subpanel 410 can extend similarly from a surrounding panel or panels as the overall locking tab 252 extends from the surrounding panel or panels. For example and without limitation, the first tab subpanel 410 can extend from the first main panel 110. The second tab subpanel 420 can extend from the first tab subpanel 410 and be joined to the first tab subpanel 410 at a bend line 415 defined therebetween. The third tab subpanel 430 can extend from the second tab subpanel 420 and can be joined to the second tab subpanel 420 at a bend line 425 defined therebetween. In some aspects, as shown, the third tab subpanel 430 can extend from an end of the second tab subpanel 420 that is distal to an end coincident with the bend line 415 defined by a connection between the first tab subpanel 410 and the second tab subpanel 420. In other aspects, the third tab subpanel 430 can extend from a different horizontal or vertical end of the second tab subpanel 420 and even extend from an internal horizontal or vertical edge of the second tab subpanel 420 and can, for example and without limitation, be positioned within the second tab subpanel 420 and also define an internal opening in the second tab subpanel 420. Each of the first tab subpanel 410, the second tab subpanel 420, and the third tab subpanel 430 can define a first end, a second end, a third end, and a fourth end. As shown, the first tab subpanel 410 can be joined at least in part to a panel such as the first main panel 110 with a perforated connection 411 to facilitate later removal of the locking tab 252 during use and, more specifically, opening of the box 1000. As such, the first tab subpanel 410 can be a punch-out tab configured to break free from the first main panel 110 upon lifting of the main panel 110. A remainder of the locking tab 252 can be fully cut or separated from the surrounding panel or panels.

In some aspects, as shown, the locking tab 252 can define a rectangular shape with corners at intersecting ends of the first tab subpanel 410 and the third tab subpanel 430 defining a radius, a chamfer, or similar corner treatment. The locking tab 252 can define one or more notches 440 in the second tab subpanel 420 and in the third tab subpanel 430. The notches 440 can be centered at the bend line 425 and can define a notch depth 427 measured relative to an edge of the locking tab. As shown, the bend line 415 can be offset from a bend line defined between the first main panel 110 and the first end panel 210 by an offset distance 417, and a distal edge or distal end 432 of the third tab subpanel 430 can be offset from the second end 212 of the first end panel 210 by an offset distance 437.

FIG. 5A is a detail view of the locking opening 258 of FIG. 3 taken from detail 5 of FIG. 3. As shown, the locking opening 258 can be or can define a closed shape and can be centered about and symmetrical about a central axis 501 of the locking opening 258. More specifically, the locking opening 258 can define a top end or first end 551, a second end 552, a third end 553, and a fourth end 554. The first end 551 of the locking opening 258 can be offset from the fourth end 394 of the bending tab 298 by an offset distance 520. The third end 553—and similarly the fourth end 554—can be angled with respect to the first end 551 by a slope angle 557. The second end 552 of the locking opening 258 can define a semicircular notch 558, which can facilitate punching out from the blank 100 a portion of the bending tab 298 defining the locking opening 258 by, for example and without limitation, a tool. In comparison to a straight cut to form the second end 552 of the locking opening 258, the semicircular notch 558 can also facilitate formation of the locking opening 258 and thereby, fabrication of the blank 100 more generally. In some aspects, a break line 405 represents a boundary of an aesthetic design of the locking tab 252. The locking tab 252 and, in some aspects as shown, the third tab subpanel 430 and the locking opening 258 can have complementary shapes so that the third tab subpanel 430 fits and even “pops” into engagement with the top edge or first end 551 of the locking opening once the locking tab 252 is sufficiently inserted.

FIG. 5B is a detail view of the locking opening of FIG. 3 taken from detail 5 of FIG. 3 in accordance with another aspect of the current disclosure. As shown in FIG. 5B and shown additionally in FIG. 6B, the locking opening 258 can be or can have an open shape, which can be a notch. In some aspects, as shown, whether a closed shape or an open shape, the first end 551 of the locking opening 258 can define a straight edge. In some aspects, a shape of the first end 551 can match a shape of the distal end 432 of the locking tab 252. For example and without limitation, in addition to both the distal end 432 of the locking tab 252 and the locking opening 258 defining a straight edge, the distal end 432 of the locking tab 252 can define a convex shape and the locking opening 258 can define a matching concave shape. In some aspects, a break line 505 represents a boundary of an aesthetic design of the locking opening 258. In any case, the locking opening 258 can be sized to receive and capture the locking tab 252 and, more specifically, at least the distal end 432 of the locking tab 252.

In some aspects, as shown, the bending tab 298 can define the locking opening 258. In some aspects, a panel other than the bending tab 298 can define the locking opening, depending on the particular arrangement of the blank 100.

As shown, any of the aforementioned panels can be joined to adjacent panels with or at bend lines defined by the intersections shown. Furthermore, any of the aforementioned panels can be a flange or a flap. Any of the aforementioned panels can further facilitate, for example and without limitation, rigidity of the box 1000 and portions thereof by preventing or limiting deformation of the first main panel 110, the second main panel 120, and other portions of the box 1000 when loaded by a force resulting from a weight of contents of the box 1000 or external forces applied thereto.

As shown, any of the aforementioned panels can define an exemplary radii R (shown in FIG. 2), chamfer, or other corner treatment at intersecting ends, edges, or corners. Any of the aforementioned panels can be planar. Any of the aforementioned edges can be aligned with one of the longitudinal axis 101 (shown in FIG. 1) and the transverse axis 102 of the blank 100. Any of the aforementioned features of the blank 100, including the locking device 250, can be symmetrical about the longitudinal axis 101 on the blank 100 or in the assembled box 1000 or about the local central axes 401,501.

As shown, one or more edges or entire sides or even all sides of the blank 100 can be substantially aligned (i.e., aligned except for the insert tabs, corner radii or chamfers, and sloped or angled ends) or fully aligned, i.e., collinear. Such substantial alignment can improve utilization of material from which the blank 100 is cut or, in the case of full alignment, increase material utilization to near 100% not considering openings from which scrap material can be nonetheless cut and removed.

FIG. 6A is a detail front partial cutaway view of the assembled box 1000 formed from the blank 100 of FIG. 1 showing the locking tab 252 of FIG. 2 engaged with the locking opening 258 of FIG. 5A. The tab subpanels 410,420,430 of the locking tab 252 can be bent relative to each other. More specifically the second tab subpanel 420 can be bent relative to the first tab subpanel 410 and the third tab subpanel can be bent relative to the second tab subpanel 420. As shown (more specifically in FIG. 7A), the third tab subpanel 430 of the locking tab 252 can be configured to engage an edge or end such as the first end 551 of the locking opening 258 when the second tab subpanel 420 and the third tab subpanel 430 are substantially parallel (i.e., parallel or nearly parallel to the degree required to fit in a space configured to receive the locking tab 452) and a surface of each in facing engagement with each other—to at least the degree required by the space between the second end panel 220 and the inside end panel 230 as shown in such an arrangement in FIG. 7A—and in close proximity and can thereby be configured to prevent movement of the locking tab 252 with respect to the locking opening 258 in an opening direction of the locking device 250 and the box 1000. As shown, a taper defined at an end of the bent locking tab 252, which can be formed by the notches 440, can define a taper angle 607 and can facilitate insertion of the locking tab 252 into the opening 352 (shown in FIG. 7A) and into the locking opening 258. In some aspects, an end of the locking tab 252 in a bent condition can be narrower than a maximum width of the locking tab 252. Regardless of the shape of the cutout or hole represented by the locking opening 258, the distal end 432 of the locking tab 252 can engage an edge such as the first end 551 defined in the bending tab 298.

FIG. 6B is a detail front partial cutaway view of the assembled box 1000 formed from the blank of FIG. 1 showing the locking tab of FIG. 2 engaged with the locking opening of FIG. 5B in accordance with another aspect of the current disclosure. As shown, the locking opening 258 can define an open shape, which can be a notch as shown defined in the bending tab 298 and defining the first end 551.

FIG. 7A is a sectional view of the assembled box 1000 of FIG. 6A at a centerline of a locking device 250 comprising the locking tab 252 of FIG. 2 and a panel such as the bending tab 298 defining the locking opening 258. The locking tab 252 and, more specifically, the third tab subpanel 430 of the locking tab 252 is shown engaged with the locking opening 258 and, more specifically, the first end 551 thereof in a closed position of the box 1000. As shown, the third tab subpanel 430 can be bent inwards and upwards relative to the second tab subpanel 420. Such engagement prevents upward movement of the first main panel 110 relative to the second main panel 120 without damage to the box 1000 such as by tearing of the locking tab 252 from the box 1000 at, in some aspects, the perforated connection 411 (shown also in FIG. 4). In some aspects, the strength of the locking device 250, i.e., the connection between the locking tab 252 and the panel defining the locking opening 258 can be adjusted by increasing or decreasing the offset distance 520 (shown in FIGS. 5A and 5B), by increasing or decreasing a space receiving the locking tab 252, and otherwise adjusting to respectively strengthen or weaken the connection.

As shown, the insertion tab 398 of the bending tab 298 and one of the insertion tabs 338 of the inside end panel 230 can be received within the opening 328. Similarly, the insertion tab 388 (shown in FIG. 3) of the bending tab 288 (shown in FIG. 3) and another of the insertion tabs 338 of the inside end panel 230 can be received within the opening 318 (shown in FIG. 3). A distal or bottom end of each of the insertion tabs 338,388,398 can be substantially co-planar (i.e., flush or nearly flush) with the outer surface 104 of the second main panel 120. In some aspects, part tolerances and other manufacturing or assembly considerations may not make the parts exactly flush in every instance, but it can be desirable to main a substantially co-planar relationship to avoid a situation where the insertion tabs 338,388,398 extend so far beyond the second main panel 120 that the insertion tabs 338,388,398 interfere with use of the box 1000.

FIG. 7B is a sectional view of the assembled box 1000 of FIG. 6B at a centerline of a locking device 250 comprising the locking tab 252 of FIG. 2 and the bending tab 298 defining the locking opening 258 in accordance with another aspect of the current disclosure. As shown, the locking tab 252 can engage the first end 551 of the locking opening 258 when defining a more open shape.

Again, as shown, the second tab subpanel 420 can be bent with respect to the first tab subpanel 410 towards the outer surface 104 about the bend line 415, and the third tab subpanel 430 can be configured to bend with respect to the second tab subpanel 420 in the same direction—towards the outer surface 104 and towards the second tab subpanel 420 of the locking tab 452—about the bend line 425. As shown here and in FIG. 10, the second tab subpanel 420 can be bent down and towards the second main panel 120 to substantially match an orientation of the end panels 220,230 in the assembled box 1000. Meanwhile, the third tab subpanel 430 can be bent towards an inside of the box 1000 until it lies flat or substantially flat against the second tab subpanel 420 so that, again, the tab subpanels 420,430 are in facing engagement.

As described in some aspects above, an entirety of the box 1000 can be formed from the blank 100 and, more specifically, can be formed from the monolithic (i.e., one-piece) blank 100 without tearing any portion of the blank 100 from any other portion thereof.

In some aspects, portions of the box 1000 can be formed from more than one blank. A box top can comprise the first main panel 110 and the first end panel 210, including the locking tab 252 and extending from an end of the first main panel 110, and can be formed from a first blank; and a box bottom can comprise the second main panel 120 and the second end panel 220 and can be formed from a second blank. In other aspects, the box top and the box bottom and as many as all of the structural elements shown in FIG. 1 can be formed from a single blank 100 of material.

FIG. 8 is a top perspective view of the first end 121 of the second main panel 120 and surrounding structure of the blank 100 of FIG. 1 in a partially assembled condition. As shown, facing the inner surface 103, the bending tabs 288,298 are bent partially inward and the inside end panel 230 is also bent partially inward.

FIG. 9 is a top perspective view of the first end 121 of the second main panel 120 and surrounding structure of the blank 100 of FIG. 1 in a further assembled condition. As shown, the bending tabs 288,298 are bent further inward relative to the partially assembled condition shown in FIG. 8 and the second end panel 220 is also bent partially inward towards the bending tabs 288,298. The bending tab 298 and, more specifically, the insertion tab 398, is shown engaged with the opening 328 and the locking opening 258 is shown aligned with the opening 352. As shown, the locking opening 258 shown defined in the bending tab 298 can be defined in a panel angled with respect to the second main panel 120 of the box bottom. More specifically, the locking opening 258 can be angled with respect to the second main panel 120 of the box bottom by an angle of substantially or exactly 90 degrees.

FIG. 10 is a front top perspective view of the assembled box 1000 of FIG. 6. As shown, the box 1000 is full assembled including the box bottom comprising the second main panel 120 and the box top comprising the first main panel 110. Shown bent with respect to the main panels 110,120 are, respectively, the side panels 260,270 and the side panels 280,290. The locking tab 252 is shown partially bent at the bend lines 415,425 in preparation for engagement with the opening 352. As shown, the locking tab 252 can be angled with respect to the first main panel 110 of the box top. More specifically, the locking tab 252 can be angled with respect to the first main panel 110 of the box top by an angle of substantially or exactly 90 degrees. The second tab subpanel 420 is shown partially bent down and towards the second main panel 120, the third tab subpanel 430 is shown bent towards an inside of the box 1000. In some aspects, as shown, the box 1000 can be a rectangular prism defining an overall length, an overall width, and an overall height or thickness. Including when shaped as a rectangular prism, each overall dimension (length, width, or height) can be orthogonal to the other dimensions. In some aspects, the box 1000 can have a shape other than that of a rectangular prism. Specifically, in some aspects, the box 1000 can have a shape of a typical pizza box, and can vary depending on the desired size of pizza to be contained within the box 1000.

FIG. 11 is a detail perspective view of the assembled box 1000 of FIG. 10 taken from detail 11 of FIG. 10. One or more elements of the construction of the box 1000 can define a gap 1180 coincident with the opening 352, sized to receive the locking tab 252 (shown in FIG. 10). In some aspects, as shown, the gap 1180 can be defined between the bending tab 298 and the second end panel 220. In some aspects, unfolding forces from one or more bends of the box 1000 can create the gap 1180. In some aspects, for example and without limitation, unfolding forces at a bend line defined at the ends 121,222 (both shown in FIG. 3)—can create the gap 1180 at the opening 352 between the bending tab 298 and the second end panel 220. In some aspects, unfolding forces at other bends can facilitate creation of the gap 1180 shown. In some aspects, the gap 1180 can thus naturally be defined on an outside of the bending tab 298 (i.e., between the bending tab 298 and the second end panel 220) instead of on an inside of the bending tab 298. In some aspects, regardless of the specific construction, it can be beneficial to position the gap 1180 and therefore also the locking tab 252 on the outside of the bending tab 298 as shown. In some aspects, however, the gap 1180 can be defined between the bending tab 298 and the inside end panel 230. In such aspects, a user of the box can nonetheless insert the locking tab 252 where desired (such as between the bending tab 298 and the second end panel 220) by manipulating the panels of the box 1000 as needed if the construction does not cause the gap 1180 to appear where desired. In some aspects, the third tab subpanel of the locking tab 252 can be bent in an opposite direction from the direction of bending shown in FIG. 10 and elsewhere (i.e., toward the front or toward the outer surface 104 of the blank 100).

With the gap 1180 for the locking tab 252 defined between the bending tab 298 and the second end panel 220 and the locking tab bent as shown in FIG. 10, the third tab subpanel 430 becomes inaccessible behind both the second tab subpanel 420 and the second end panel 220. In some aspects, as shown in FIG. 7A, the third tab subpanel 430 is hidden behind the second tab subpanel 420 and the second end panel 220 and cannot become accessible. More specifically, engaged portions of the locking tab 252 and the locking opening 258 can be hidden behind the locking tab 252 relative to an observer outside of the locking device 250 when the locking device 250 is in an assembled position, wherein hidden means to not be visible to the observer when the panels forming the box 1000 are made from an opaque material. More specifically, any attempt to remove or lift the locking tab 252 will cause an edge of the distal end 432 of the third tab subpanel 430 to engage and be retained by the top edge of first end 551 of the locking opening 258. Opening of the box 1000 can thereby result in indications of tampering such as, for example and without limitation, by tearing of separation of the locking tab 252 at the aforementioned perforated connection 411 (shown in FIG. 4) or, in some aspects, tearing of the bending tab 298 between the first end of the locking opening 258 and the fourth end 394 of the bending tab 298. As such, the locking device 250 can be a tamper-evident locking device 250 that notifies the recipient of the box 1000 before even opening the box 1000 that the box 1000 was previously opened and any goods contained therein accessed.

FIGS. 12 and 13, respectively, show detail side perspective views of the assembled box 1000 of FIG. 10 showing the locking device 250 of FIG. 7 before and during insertion into the gap 1180 and engagement with the locking opening 258 (shown in FIGS. 5A and 5B). As the locking tab 252 is inserted into the gap 1180 in a closing direction 1210 by a force F applied to a surface of the first tab subpanel 410, the third tab subpanel 430 is pressed toward the second tap subpanel 420 (as shown in FIG. 13). As shown, a taper defined at the end of the locking tab 252, which can be formed by the notches 440, can facilitate insertion of the locking tab 252 into the opening 352 and into the locking opening 258. The compression of the material of the locking tab 252 caused by bending the third tab subpanel 430 about the bend line 425 (shown in FIG. 12) toward the second tab subpanel 420 can cause the third tab subpanel 430 to “spring” back away from the second tab subpanel 420 in an effort to unfold as the third tab subpanel clears the bending tab 298 (shown in FIG. 11) and is received within the locking opening 258 (shown in FIGS. 5A and 5B). This tendency for the third tab subpanel 430 to unfold can keep the locking tab 252 engaged with the locking opening 258 even during jostling of the box 1000 that may be experienced during shipping of the box 1000 and during any attempts to open the box 1000 without breaking off the locking tab 252.

FIG. 15 is a perspective view of the assembled box of FIG. 10 showing the locking device 250 of FIG. 7A after separation of the locking tab 252 from the first main panel 110. In some aspects, upon lifting of the pull tab 216 in an opening direction 1410, the box top comprising the first main panel 110 can separate from the box bottom comprising the second main panel 120 by tearing and separation of the locking tab 252 from the first main panel 110 at the perforated connection 411 now shown torn. Opening the box 1000 in the opening direction 1410 can cause a shearing stress at the perforated connection 411 that exceeds the strength of the perforated connection, thereby resulting in the tearing and separation of the locking tab 252. In some aspects, upon separation of the locking tab 252 from the first main panel 110 at the perforated connection 411 now shown torn—for example and without limitation, by either pushing down or lifting up a portion of the locking tab such as the first tab subpanel 410, optionally with an additional opening not shown to facilitate the pushing down or lifting up—the box top comprising the first main panel 110 can then separate from the box bottom comprising the second main panel 120. In some aspects, opening the box 1000 can comprise lifting the pull tab 216 with one hand and pushing down or lifting up the locking tab 252 with another hand. As shown, the first main panel 110 and the first end panel 210 can define an opening 1452 matching a shape of the locking tab 252. Up to and including all of the panels of the box 1000 including the side panels 260,270 and the first end panel 210 can be positioned inside the side panels 280,290 in an assembled condition of the box 1000 (to further hide portions of the box 1000 that upon bending might expose the contents of the box 1000).

The blank 100 and the box 1000 and any portion thereof can be formed from a cardboard material such as, for example and without limitation, corrugated cardboard or plastic. The material forming the blank 100 and the box 1000 can be tearable, i.e., it can have sufficiently low tensile strength to be torn during opening of the box with an easily applied opening force. For example, in some aspects, the blank 100 and the box 1000 can be formed from any corrugated material including micro flutes and larger flutes including, for example and without limitation, “A” flute material. More specifically, the blank 100 and the box 1000 can be formed from any range of materials including “F” flute or less (defining a nominal thickness of 1/32 inch or 0.8 mm), “E” flute or less (defining a nominal thickness of 1/16 inch or 01.6 mm), “B” flute or less (defining a nominal thickness of ⅛ inch or 3.2 mm), or “A” flute or less (defining a nominal thickness of 3/16 inch or 4.8 mm), and also double-wall and other multi-wall corrugated material. In some aspects, the blank 100 and the box 1000 can be formed from non-corrugated material. In some aspects, for example and without limitation, the blank 100 and the box 1000 can be formed from a material, including paper material, as thin as 10 pt card stock material (defining a nominal thickness of 0.010 inch or 0.254 mm). In some aspects, the perforated connection 411 can be as weak as necessary to ensure that any force to unfold the locking tab 252 internally (i.e., in a space receiving the locking tab 252, including in the gap 1180 and/or the locking opening 258 defined by the box 1000) would result in activating or tearing the perforated connection 411.

A method of assembling the locking device 250 and assembling the box 1000 can comprise folding the side panels 260,270,280,290 with respect to the corresponding main panels 110,120. The method can comprise bending or folding the first end panel 210 with respect to the first main panel 110. The method can comprise bending the bending tabs 288,298 inward into engagement with the second main panel 120 and specifically the openings 326,328 defined in the second main panel 120 or neighboring structure. The method can comprise bending the second end panel 220 with respect to the second main panel 120 into mating or proximate contact with the bending tabs 288,298. The method can comprise bending the inside end panel 230 with respect to both the second main panel 120 and the second end panel 220 into engagement with the second main panel 120 and specifically the openings 326,328. The method can comprise bending the tabs 286,296 inward and in front of the connecting panel 130. The method can comprise bending the connecting panel 130 with respect to the second main panel 120. The method can comprise bending the first main panel 110 with respect to the connecting panel 130 and the second main panel 120. The method can comprise bending the locking tab 252 as described above. The method can comprise inserting the locking tab into the gap 1180 formed by the box 1000 and into locking engagement with the locking opening 258. Inserting the locking tab into the gap 1180 can comprise “snapping” a portion of the locking tab 252 such as the third tab subpanel 430 into locking engagement with the locking opening 258. Such “snapping” can occur when the bent third tab subpanel 430 unbends or unsprings slightly upon engagement with the locking opening 258, thereby allowing potential energy created by the compressive bending of the locking tab 252 to be released in the form of movement of the locking tab 252 and, in some cases, contact with an adjacent panel. Movement of the locking tab 252 and any contact with the adjacent panel may be accompanied by an audible noise or by a tactile indication of engagement of the locking tab 252 with the locking opening 258. In some aspects, the box top comprising the first main panel 110 can be hingedly joined and bent with respect to the box bottom comprising the second main panel 120.

In some aspects, as described above, the box top and the box bottom can be formed separately, and the method of assembly can comprise joining the box top and the box bottom without rotating one with respect to the other or without the first main panel 110 joined to the second main panel 120. For example and without limitation, one or more locking tabs 252 can positioned as shown but without the hinged connection or without the box being formed from a single blank, and the one or more locking tabs 252 can be engaged with one or more corresponding panels, each defining a locking opening 258.

A method of assembling and using the box 1000 can comprise obtaining the box top comprising the first main panel 110 and the first end panel 210, at least one of the first main panel 110 and the first end panel 210 defining the locking tab 252, which can be separable from the box top. The method can comprise obtaining the box bottom comprising the second main panel 120 and the second end panel 220, the box bottom defining the locking opening 258. The method can comprise inserting the locking tab 252 into the gap 1180 defined at least in part by the second end panel 220. Inserting the locking tab 252 into the gap 118 can comprise hiding a portion of the locking tab 252 behind the second end panel 220 and capturing the third tab subpanel 430 of the locking tab within the locking opening 258. The method can comprise engaging the locking tab 252 with the locking opening 258.

A method of using the box 1000 can comprise opening the box by lifting the first main panel 110 away from the second main panel 120. The method of use can comprise breaking a perforated connection 411 between the locking tab 252 and neighboring structure such as the first main panel 110. In some aspects, the perforated connection 411 can be broken by only minimal force such that any attempt to open the box by, for example and without limitation, lifting the first main panel 110. The method of use can comprise indicating with a tamper-evident structure such as the broken perforated connection 411 that the box 1000 has been tampered with or, in the case of the user being the consumer or customer, simply opened. Moreover, when the locking tab 252 is engaged, the construction can be such that it is not possible to insert a finger under the locking tab 252 to try to apply a force only to an engaged end of the locking tab 252 such as the distal end 432 of the third tab subpanel 430. In other embodiments, indication of tampering can result from tearing or breaking, with or without defined perforations, of a portion of the bending tab 298 such as the material between the first end 551 of the locking opening 258 and the fourth end 394 of the bending tab 298.

Any feature described herein such as, for example and without limitation, the locking tab 252, the locking opening 258, other components of the blank 100 or the box 1000 and their arrangement, can comprise both functional and aesthetic elements, and any feature described as having functional aspects can have or define any one of several aesthetic designs without altering the respective parts' functions. If aesthetic elements are shown in the drawings or possibly fall within the scope of broader claim elements without being directly claimed, such disclosure or claims should not be interpreted as assigning any function to such aesthetic elements which may therefore be separately protectable.

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 comprise 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.

It should be emphasized that the above-described aspects are merely possible examples of implementations, merely set forth for a clear understanding of the principles of the present disclosure. Any process descriptions or blocks in flow diagrams should be understood as representing modules, segments, or portions of code which comprise one or more executable instructions for implementing specific logical functions or steps in the process, and alternate implementations are included in which functions may not be included or executed at all, may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those reasonably skilled in the art of the present disclosure. Many variations and modifications may be made to the above-described aspect(s) without departing substantially from the spirit and principles of the present disclosure. Further, the scope of the present disclosure is intended to cover any and all combinations and sub-combinations of all elements, features, and aspects discussed above. All such modifications and variations are intended to be included herein within the scope of the present disclosure, and all possible claims to individual aspects or combinations of elements or steps are intended to be supported by the present disclosure.
