As shown in
In one embodiment, the front panel 110 is foldably connected to a first end flap 130 and a second end flap 131. The bottom panel 116 is foldably connected to a first end flap 132 and a second end flap 133. The back panel 114 is foldably connected to a first end flap 134 and a second end flap 135. The top panel 120 is foldably connected to a first end flap 136 and a second end flap 137. The lid panel 124 is foldably connected to a first end flap 138 and a second end flap 139. As illustrated in
In the illustrated embodiment, the end flaps 130, 132, 134, 136, 138 extend along a first marginal area of the blank 103, and are foldably connected at a first longitudinal fold line 146 that extends along the length of the blank 103. The end flaps 131, 133, 135, 137, 139 extend along a second marginal area of the blank 103, and are foldably connected at a second longitudinal fold line 148 that also extends along the length of the blank 103. The longitudinal fold lines 146, 148 may be for example, substantially straight, decoratively curved, or offset at one or more locations to account for blank thickness or for other factors.
As shown in
As shown in
In one embodiment, each of the tabs 160 is defined by a cut 161 extending between respective portions 146a, 146b, 148a, 148b of the longitudinal fold lines 146, 148. In one embodiment the cut 161 includes a lateral portion 161a and two curved end portions 161b, 161c that extend from a respective portion 146a, 146b, 148a, 148b of the fold lines 146, 148. The cut 161 and the tab 160 could be otherwise shaped, arranged, and/or configured without departing from the scope of the disclosure.
As shown in
As shown in
In one exemplary method of forming the blank 103 into the carton 105, the blank 103 is first placed with the interior surface 180 facing up as illustrated in
When the blank 103 is formed into a carton 105 the locking tabs 160 extend outwardly from the front panel 110 when the end flaps 130, 131 are folded to close the carton 105. When the end flaps 138, 139 connected to the lid panel 124 are folded to close the carton 105, openings 190 are formed in the end flaps and the locking tabs 160 engage the openings 190 and/or tabs 174 to create a releasable lock. The flaps 170 can flex outward and provide added space for the locking tabs 160 when the blank 103 is formed into a carton 105. The configuration of the flaps 170 that are formed by the offset of cut 172 being spaced apart from the fold line 146, 148 provides clearance for receiving the locking tab 160 during formation of the carton 105 and positioning during opening and closing of the lid 186.
As illustrated in
In one exemplary method of initially opening the carton 105, the lid panel 124 is upwardly pulled separating the access panel 150 from the front panel 110 along tear line 152. After the access panel 150 separates from the front panel 110, the access panel 150 remains connected to the lid panel 124 and moves upwardly with the lid panel 124 when the lid 186 is moved to the open position, as illustrated in
The carton 105 may be reclosed by positioning the reclosable lid 186 in the closed position by folding the lid 186 downwardly such that the flaps 170 in the end flaps 138, 139 are brought into engagement with locking tabs 160 extending from the front panel 110. As the flaps 170 and tabs 174 slide past the locking tabs 160 an audible click is produced to provide feedback to the user that the locking features of the lid 186 are engaged. The foldable flaps 170 created by the ‘H’ style slits in the end flaps 138, 139 of the lid 186 also flex outwardly extending the opening 190 to provide added space to accommodate the locking tabs 160 without deformation to the audible lock position wherein the tabs 160 are located above tabs 174 and closely adjacent lid panel 124.
When an opening force is applied to the center of the reclosable lid 186, the sides of the lid 186 flex inwardly, as shown in
To open the reclosable lid 186 and prevent the locking force increase, the opening force may be applied to any area substantially off center, such as the edges 188, 189 of the lid 186. If the lid 186 is attempted to be opened by applying a force near the center of the carton 105, the sides of the lid corresponding to overlapped flaps 136, 138 and 137, 139 would flex inwardly resulting in inward movement of the flap 170 and displacement of the locking tabs 160 through the opening 190 and an increase in the locking force resisting the opening of the lid (
The carton 105 can be formed, closed, and/or opened by other alternative methods and steps without departing from the disclosure. As illustrated in
As illustrated in
In an alternative embodiment, one or more of end flaps 130, 131, 134, 135 could have a cut-away portion to allow adhesive applied to one or more of end flaps 136, 137 to contact end flaps 138, 139 via the cut-away portions. The end flaps 130, 131, 132, 133, 134, 135, 136, 137, 138, 139 could be otherwise shaped, arranged, positioned and/or configured without departing from the disclosure. For example, end flaps 136, 137 could be folded under end flaps 134, 135 and be adhered to end flaps 139, 139 in an alternative closing arrangement.
In general, the blank may be constructed from paperboard having a caliper so that it is heavier and more rigid than ordinary paper. The blank can also be constructed of other materials, such as cardboard, sheet plastics or any other material having properties suitable for enabling the carton to function at least generally as described above. The blank can be coated with, for example, a clay coating. The clay coating may then be printed over with product, advertising, and other information or images. The blanks may then be coated with a varnish to protect information printed on the blanks. The blanks may also be coated with, for example, a moisture barrier layer, on either or both sides of the blanks. The blanks can also be laminated to or coated with one or more sheet-like materials at selected panels or panel sections.
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.
In accordance with the exemplary embodiments, 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 or depressed 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. In situations where cutting is used to create a fold line, typically the cutting will not be overly extensive in a manner that might cause a reasonable user to incorrectly consider the fold line to be a tear line.
The above embodiments may be described as having one or more panels adhered together by glue during erection of the carrier embodiments. The term “glue” is intended to encompass all manner of adhesives commonly used to secure carton panels in place, and is not intended to exclude heat, chemical, or frequency bonding techniques.
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. Additionally, the disclosure shows and describes only selected embodiments, but various other combinations, modifications, and environments are within the scope of the disclosure as expressed herein, commensurate with the above teachings, and/or within the skill or knowledge of the relevant art. Furthermore, certain features and characteristics of each embodiment may be selectively interchanged and applied to other illustrated and non-illustrated embodiments of the disclosure.
This application claims the benefit of U.S. Provisional Patent Application No. 61/959,613, filed Aug. 28, 2013. The disclosure of U.S. Provisional Patent Application No. 61/959,613, which was filed on Aug. 28, 2013, is hereby incorporated by reference for all purposes as if presented herein in its entirety.
