In the illustrated embodiments, the bottom locking features can include a bottom closure panelfoldably connected to the bottom end panelalong a lateral fold lineand a bottom locking flapfoldably connected to the bottom closure panelalong a lateral fold line. In embodiments, the bottom locking flapcan have a distal bottom locking edgeopposite to the lateral fold line. As shown in, a retention flapcan be foldably connected to the back panelalong a lateral fold linealong the bottom marginal portion of the blank, and the retention flapcan have a distal bottom retention edgeopposite to the lateral fold line. In the illustrated embodiments, the lateral fold linecan be offset from two bottom edgesin a recess. The bottom edgescan be aligned (e.g., substantially aligned) with the lateral fold linesIn embodiments, the bottom closure featurescan include a partition panelfoldably connected to the back panelalong a longitudinal fold lineand a distal attachment flapfoldably connected to the partition panelalong a longitudinal fold line. As shown in, the distal attachment flapcan include a recessfor at least partially accommodating the bottom locking flapand the retention flap, as described in more detail below. Any of the bottom closure featurescould be omitted or could be otherwise shaped, arranged, positioned, and/or configured without departing from the disclosure.

As shown in, each of the side top structures,can include a proximal panelfoldably connected to the respective side panels,along the lateral fold line, an intermediate panelfoldably connected to the proximal panelalong a lateral fold line, and a distal panelfoldably connected to the intermediate panelalong a lateral fold line.

Alternatively, the at least a portion of the proximal panelscan be spaced apart from the top end panel. Any portion of the side top structures,could be omitted or could be otherwise shaped, arranged, positioned, and/or configured without departing from the disclosure. The blankcould be otherwise shaped, arranged, positioned, and/or configured without departing from the disclosure.

According to exemplary methods of construction, the cartonmay be erected by folding and gluing or otherwise securing the blankas shown in. For example, the blankcan be positioned with its interior surfacefacing up, and the side top structures,can be folded along the lateral fold linesto fold the intermediate panels, the distal panels, and the end attachment flapsto be in an overlapping relationship with the interior surfaces of the respective proximal panelsand the respective side panels,. In embodiments, the end attachment flapscan be attached (e.g., glued and/or otherwise secured) in face-to-face contact with the respective side panels,. As shown in, the side bottom end flaps,can be folded along the bottom fold linesto be in an overlapping relationship with the respective side panels,, and, in embodiments, the bottom end flaps,can be attached (e.g., glued and/or otherwise secured) in face-to-face contact with the respective side panels,. In the illustrated embodiments, the distal spacer flapcan be folded along the lateral fold lineto be in an overlapping relationship with the top locking panel. For example, the distal spacer flapcan be attached (e.g., glued and/or otherwise secured) in face-to-face contact with the top locking panel. As shown in, the edge formed along the lateral fold linecan be a top locking edgeof the top closure.

As shown in, the back flapand the retention flapcan be folded along the respective lateral fold lines,to be in an overlapping relationship with the back panel. In embodiments, the back flapand the retention flapcan be attached (e.g., glued and/or otherwise secured) in face-to-face contact with the back panel. In the illustrated embodiments, the distal attachment flapcan be folded along the longitudinal fold lineinto overlapping relationship with the partition panel(e.g., in face-to-face contact with the interior surface of the partition panel), and, subsequently to the folding of the retention flap, the partition panelcan be folded along the longitudinal fold lineinto overlapping relationship with the back panelwith the distal attachment flappositioned between (e.g., sandwiched between) the partition paneland the back panel(e.g., so that the partition panel, the back panel, and the distal attachment flapare in an overlapping relationship). In embodiments, the distal attachment flapcan be attached (e.g., glued and/or otherwise secured) in face-to-face contact with the back panel.

As shown in, the partially formed construct ofcan be folded and glued and/or otherwise secured to at least partially form an open-ended sleeve. For example, the back panelcan be folded along the longitudinal fold lineto be in an overlapping relationship with the second side paneland the front paneland the first side panelcan be folded along the longitudinal fold lineso that the first side panelis in an overlapping relationship with the front paneland the attachment flapis in an overlapping relationship with the back panel. In embodiments, the attachment flapcan be attached (e.g., glued and/or otherwise secured) in face-to-face contact with the back panel. As shown in, the open-ended sleeve can be folded flat (e.g., for transportation and/or storage), providing a pre-glued cartonthat is ready to be erected, packed/loaded, and closed (e.g., by hand and/or by mechanical systems). For example, the cartoncan be erected from the flattened configuration ofto be configured as an open ended sleeve as shown in, wherein the cartonis folded along the longitudinal fold lines,,,to position the front paneland the back panelto be spaced apart and to be disposed opposite one another and to position the side panels,to be spaced apart and to be disposed opposite one another. As shown in, the plurality of panels including at least the front panel, the back panel, and the side panels,can extend at least partially around an interiorof the carton. The cartoncould be otherwise formed and/or erected without departing from the scope of the disclosure.

As shown in, the bottom endcan be closed with the bottom closure. For example, the bottom locking flapcan be folded along the lateral fold lineoutwardly with respect to the bottom closure panel, and both of the bottom closure paneland the bottom locking flapcan be folded along the lateral fold linetoward the interiorof the cartonand can be inserted into a gapbetween the partition paneland the back panel. For example, as the bottom end panelis folded over the bottom endof the cartoto at least partially close the bottom end, the bottom locking flapand the bottom closure panelcan be inserted into the gapwith the lateral fold lineentering the gapfirst and the bottom closure paneland the bottom locking flapin an at least partially overlapping relationship. Accordingly, the bottom locking flapand the bottom closure panelcan be positioned between (e.g., sandwiched between) the partition paneland the retention flapas they are inserted into the gap. In embodiments, as the bottom locking flapand the bottom closure panelare moved further into the gap, the bottom locking flapcan slide along the retention flapuntil the bottom locking edgeslides past the bottom retention edgeof the retention flap. In the illustrated embodiments, the natural spring back of the blank material can at least partially bias the bottom locking flapoutward, away from the bottom closure paneland toward the back panel. Accordingly, the bottom locking flapcan move (e.g., snap) outwardly against the interior surface of the back panelwhen the bottom locking edgemoves past the retention edge. The outward movement of the bottom locking flapcan move the bottom locking flapinto alignment with the retention flapso that the bottom locking edgeand the retention edgeare in aligned and opposing relationship with one another.

As described, the bottom closurecan be folded towards the interiorof the cartonand the bottom locking flapcan slide past the retention flapuntil the bottom locking flapand the retention flapbecome engaged (e.g., locked). For example, the spring back of the blank material can bias the bottom locking flapoutwardly so that the bottom locking flapfolds outwardly against the interior surface of the back panelwhen the bottom locking flapmoves past the retention flap. Accordingly, the bottom locking edgeof the bottom locking flapcan engage the retention edgeof the retention flapso that the bottom locking edgeand the retention edgeare at least partially aligned. For example, the bottom locking edgecan engage and/or contact the retention edgeso that the retention flapblocks the bottom locking flapand prevents the bottom locking flapand the remainder of the bottom closurefrom moving outwardly (e.g., opening) if a force is applied to the bottom end panelthat may otherwise fold the bottom closureoutwardly from the interior of the carton(e.g., if one attempts to pull the bottom closureopen).

The closed and locked bottom endis shown in.shows the bottom locking features engaged in the interior of the carton, for example, with hidden features shown with broken lines. As shown in, the recessin the distal attachment flapcan at least partially accommodate the bottom locking flapand the retention flapwhen the bottom closureis closed and the distal attachment flap, the retention flap, and the bottom locking flapare at least partially coplanar in the gapbetween the partition paneland the back panel. In embodiments, the closed bottom closurecan be at least partially recessed at the bottom(e.g., with respect to the back paneland the side panels,). For example, the bottom edgesof the back paneland the bottom fold linesandcan be spaced below the bottom paneland the remainder of the bottom closure. In embodiments, the bottom closurealso can lack any tabs or other access points so that opening of the bottom closureis difficult or impossible (e.g., without cutting or tearing the carton) once the bottomis closed and locked. The bottom endcould be otherwise closed and/or locked without departing from the disclosure.

In the illustrated embodiments, the top endcan be closed and locked as shown in. For example, the side top end structures,can be folded along the lateral fold linesand into the interiorof the carton(). In embodiments, the side top end structures,can fold along the fold lines,,and the distal panelscan separate from and be disposed opposite to the respective proximal panelswith the intermediate panelsextending between the respective proximal panelsand distal panelsas the side top end structures,are folded into the interior. As shown in, the proximal panelof the side top end structurecan extend horizontally (e.g., generally and/or substantially horizontally) from the side panelat the top end, and, as schematically shown in the partial breakaway view of, the distal panelcan extend horizontally (e.g., generally and/or substantially horizontally) from the side paneland the end attachment flapinto the interiorwith the intermediate panel extending vertically (e.g., generally and/or substantially vertically) between the proximal portionand the distal portion, in examples. As shown in, for example, the retention shoulderscan extend outwardly from the proximal panelstoward the back panelwhen the side top end structures,are in position in the interiorat the top end.

As shown in, the top locking panelcan be folded along the fold lineand into overlapping relationship with the top closure panelwith the distal spacer flapsandwiched therebetween. As shown in, the pull tabcan be inserted at least partially through the slot. As shown in, the top closurecan be folded towards the interior of the cartonso that the top end panelat least partially closes the top endand the top locking paneland the top closure panelare inserted between the top side end structures,and the back flap(which can be glued in face-to-face contact with the back panel). As the top closureis moved to the closed position, the top locking panelcan slide along the outer edges of the shouldersuntil the top locking paneland the top locking edgemove past (e.g., below) the shoulders, wherein the spring back of the carton material can bias the top locking panelaway from the top closure panelinto the interiorso that the top locking paneland the top locking edgemove under the shoulders. In the illustrated embodiments, the shoulderscan be spaced apart from one another to define a recess or gap therebetween, and the pull tabextending upwardly from the top locking edgecan be at least partially received between the shouldersin the recess or gap as the top locking panelmoves under the shoulders. As schematically shown in, the top locking panelcan contact an edge of the intermediate panelsand/or the pull tabcan contact an edge of the top end panelextending along the slotand/or an edge of the proximal panelsto resist and/or prevent further movement of the top locking panelaway from the top closure panel. The top closurecould be otherwise actuated to at least partially close the top endand/or could be otherwise locked without departing from the disclosure. Further, the ends,could be closed in any order and carton can be packed/loaded before closing the ends and/or after closing one of the ends.

The closed and locked top closureis shown inwith the pull tabextending upwardly through the slotand the unactuated push tabextending in the back panel(). As schematically shown in the partial breakaway view of, the top locking panelcan extend under the shouldersof the top side end structures,to lock the top closurein the closed configuration. For example, the spring back of the blank material can bias the top locking panelaway from the back flapand the back panel. Forces that may tend to move the top closureupwardly away from the interior of the cartoncan cause the top locking edgeof the top locking panelto contact the proximal panelsof the side top end structures,under the shoulders, which can prevent further folding of the top closureand keep the top closurein the closed position.

As shown in, the top closureselectively can be unlocked and opened by actuating the pull taband the push tab. For example, a user can pull on the pull tab(e.g., in the direction of the arrow A) to move the pull tabtoward the back panelagainst the bias of the spring back forces of the blank/carton material. In embodiments, this can move the top locking paneltoward the back panel. As schematically shown in the partial breakaway view of, the top locking paneland the top locking edgeare moved outwardly of the shouldersso that the shouldersdo not interfere with the movement of the top locking panelwhen the pull tabis actuated as shown in. In exemplary embodiments, the push tabcan be actuated (e.g., pushed inwardly through the opening) so that the push tabfolds upwardly along the fold line(e.g., as shown by arrow A) in the interiorof the carton, at least partially forming an access openingin the back panel(). As schematically shown in the partial breakaway view of, the actuated push tabcan push upwardly in the direction of arrow Aon the top closure paneland the top locking panel(e.g., pushing on the fold lineconnecting the top closure paneland the top locking panel) to push the top closureso that the top closurefolds along the lateral fold lineaway from the interior of the carton() to open the top end(). In embodiments, once the top closure edgemoves past the shoulders, a user can continue to open the top closureby pulling upwardly on the pull taband/or other portions of the top closure to pivot the top end panelaway from the top end. Once the top closureis opened, the side top end structures,can be pivoted upwardly out of the interiorto provide access to the interiorof the cartonand/or to the contents (not shown) of the carton.

In the illustrated embodiments, the top closurecan be reclosed as shown in(e.g., as described above). In exemplary embodiments, the locking features can make an audible noise (e.g., a click sound) when the top endis closed and the locking features are engaged to indicate to a user that the cartonis locked in the closed configuration. The cartoncould be otherwise formed and/or closed without departing from the disclosure.

In embodiments, the top side end structures,can help protect the one or more products (e.g., a glass jar or other suitable articles) in the interior of the cartonas well as at least partially form an integrated locking mechanism along with a tuck-in flap (e.g., formed by the top locking paneland the top closure panel). In embodiments the spring back forces of the blank material can facilitate locking of the top closure. As described above, a two-step process can be used to open the top endof the cartonby pulling on the pull taband pushing on the push tab. In the illustrated embodiments, the bottom endalso can include a locking feature, which is difficult or impossible to be opened once closed and locked due to a lack of access areas, for example. In embodiments, this configuration of the blankand the cartoncan allow the cartonto be erected (e.g., from the pre-glued, open-ended sleeve configuration of), loaded, and closed without the need for additional glue or machinery. For example, the carton can be filled and closed securely by hand without the need for additional glue. Accordingly, the cartoncan provide a child-proof and/or child-resistant package that can be filled and closed/locked by hand without the need for additional gluing operations or for investing in machinery, etc.

Any of the features of the various embodiments of the disclosure can be combined with, replaced by, or otherwise configured with other features of other embodiments of the disclosure without departing from the scope of this disclosure. Further, the panels, flaps, and/or other features shown and described in conjunction with the blanks, the cartons, and/or the packages of the above embodiments are included by way of example. The closure features and/or other features of the disclosure can alternatively be associated with any suitable carton or blank having any panel and flap configuration.

The cartons according to the present disclosure can be, for example, formed from blanks of coated paperboard and similar materials. For example, the interior and/or exterior sides of the blanks can be coated with a clay coating. The clay coating may then be printed over with product, advertising, price coding, and other information or images. The blanks may then be coated with a varnish to protect any information printed on the blank. The blanks may also be coated with, for example, a moisture barrier layer, on either or both sides of the blank. In accordance with the above-described embodiments, the blanks may be constructed of paperboard of a caliper such that it is heavier and more rigid than ordinary paper. The blanks can also be constructed of other materials, such as cardboard, hard paper, or any other material having properties suitable for enabling the carton to function at least generally as described herein. The blanks can also be laminated or coated with one or more sheet-like materials at selected panels or panel sections.

In accordance with the above-described embodiments of the present disclosure, a fold line can be any substantially linear, although not necessarily straight, form of weakening that facilitates folding therealong. More specifically, but not for the purpose of narrowing the scope of the present disclosure, fold lines include: a score line, such as lines formed with a blunt scoring knife, or the like, which creates a crushed portion in the material along the desired line of weakness; a cut that extends partially into a material along the desired line of weakness, and/or a series of cuts that extend partially into and/or completely through the material along the desired line of weakness; and various combinations of these features.

As an example, a tear line can include: a slit that extends partially into the material along the desired line of weakness, and/or a series of spaced apart slits that extend partially into and/or completely through the material along the desired line of weakness, or various combinations of these features. As a more specific example, one type of tear line is in the form of a series of spaced apart slits that extend completely through the material, with adjacent slits being spaced apart slightly so that a nick (e.g., a small somewhat bridging-like piece of the material) is defined between the adjacent slits for typically temporarily connecting the material across the tear line. The nicks are broken during tearing along the tear line. The nicks typically are a relatively small percentage of the tear line, and alternatively the nicks can be omitted from or torn in a tear line such that the tear line is a continuous cut line. That is, it is within the scope of the present disclosure for each of the tear lines to be replaced with a continuous slit, or the like. For example, a cut line can be a continuous slit or could be wider than a slit without departing from the present disclosure.

The above embodiments may be described as having one or more panels, flaps, or features, adhered together by glue during erection of the carton embodiments. The term “glue” is intended to encompass all manner of adhesives commonly used to secure carton panels in place.

The foregoing description of the disclosure illustrates and describes various embodiments. As various changes could be made in the above construction without departing from the scope of the disclosure, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. Furthermore, the scope of the present disclosure covers various modifications, combinations, alterations, etc., of the above-described embodiments that are within the scope of the claims. Additionally, the disclosure shows and describes only selected embodiments of the disclosure, but the disclosure is capable of use in various other combinations, modifications, and environments and is capable of changes or modifications within the scope of the inventive concept as expressed herein, commensurate with the above teachings, and/or within the skill or knowledge of the relevant art.
