In the illustrated embodiment, the inner member 61 and the outer member 60 may include locking features for cooperating to resist and / or limit movement of the inner member 61 relative to the outer member 60, as described in more detail below. In addition, the inner member 61 and / or the outer member 60 may include an audible feature that indicates when the inner member is in a closed / locked position of the carton 68, as described in more detail below. In an exemplary embodiment, the blanks 1, 25 may be made of paperboard, cardboard, corrugated board, or other suitable materials.

[0024] like Figure 1 As shown, the first blank 1 has a longitudinal direction L1 and a transverse direction L2. In the embodiment shown, the first blank 1 may have a bottom wall or panel 2, which is foldably connected to four first side walls or inner panels 3, 4, 5, 6 at its edges along respective fold lines 2.1, 2.2, 2.3, 2.4. For example, the bottom panel 2 may be foldably connected to respective first inner side panels 3 and second inner side panels 5 along respective transverse fold lines 2.1, 2.3, and the bottom panel 2 may be foldably connected to respective first inner end panels 4 and second inner end panels 6 along respective longitudinal fold lines 2.2, 2.4. Figure 1 As shown, at least the bottom panel 2 and the inner end panels 4, 6 may be rectangular. Any of the bottom panel 2 and / or the inner panels 3, 4, 5, 6 may be omitted or may have other shapes, arrangements and / or configurations without departing from the present disclosure.

[0025] In the illustrated embodiment, the inner panel 3 may be foldably connected to the first or inner locking tabs 9.1, 9.2 at respective transverse fold lines 7.1, 7.2. Similarly, the inner panel 5 may be foldably connected to the first or inner locking tabs 10.1, 10.2 at respective transverse fold lines 8.1, 8.2. Figure 1As shown, each internal locking tab 9.1, 9.2 may include a respective first / triangular portion 11.1, 11.2 and a respective second / rectangular portion 11.3, 11.4, and each internal locking tab 10.1, 10.2 may include a respective first / triangular portion 12.1, 12.2 and a respective second / rectangular portion 12.3, 12.4. In the illustrated embodiment, the second portion 11.3, 11.4 of the locking tabs 9.1, 9.2 has a locking edge 13.1, 13.2 spaced from the fold lines 7.1, 7.2. In the illustrated embodiment, the second portion 12.3, 12.4 of the internal locking tabs 10.1, 10.2 has a locking edge 14.1, 14.2 spaced from the fold lines 8.1, 8.2. The portions 11.1, 11.2, 11.3, 11.4, 12.1, 12.2, 12.3, 12.4 of the inner locking tabs 9.1, 9.2, 10.1, 10.2 may have alternative sizes and shapes to those shown and / or described herein without departing from the scope of the present disclosure.

[0026] like Figure 1 As shown, the first inner panel 3 is foldably connected to the inner locking flap 19 at the transverse fold line 21, and the inner panel 5 is foldably connected to the inner locking flap 20 at the transverse fold line 22. In one embodiment, the inner locking flap 19 is spaced apart from the adjacent inner locking tabs 9.1, 9.2, and the inner locking flap 20 is spaced apart from the adjacent inner locking tabs 10.1, 10.2. In the illustrated embodiment, the distance that the distal edge 19.1 of the inner locking flap 19 is spaced apart from the fold line 21 is less than the distance that the locking edges 13.1, 13.2 are spaced apart from the corresponding fold lines 7.1, 7.2. Therefore, the locking flap 19 extends from the inner panel 3 a distance less than the inner locking tabs 9.1, 9.2. Likewise, the distal edge 20.1 of the inner locking flap 20 is spaced from the fold line 22 by a distance less than the distances that the locking edges 14.1, 14.2 are spaced from the respective fold lines 8.1, 8.2, and the inner locking flap 20 extends from the inner panel 5 a distance less than the inner locking tabs 10.1, 10.2. The inner locking flaps 19, 20 may have other shapes, arrangements and / or locations without departing from the present disclosure.

[0027] like Figure 1As shown, the first inner panel 3 is foldably connected to the respective inner dust flaps or inner end flaps 15, 16 along the respective longitudinal fold lines 3.1, 3.3. Similarly, the second inner panel 5 is foldably connected to the respective inner dust flaps or inner end flaps 17, 18 along the respective longitudinal fold lines 5.1, 5.3. In an embodiment, the longitudinal fold lines 3.1, 3.3 and 5.1, 5.3 may extend along a rectangular section of the respective inner panel 3, 5. Any of the inner locking tabs 9.1, 9.2, 10.1, 10.2, the inner locking tabs 19, 20, the inner end flaps 15, 16, 17, 18 and / or the inner panels 3, 5 may be omitted or may have other shapes, arrangements and / or configurations without departing from the present disclosure.

[0028] The blank 1 may have other shapes, arrangements and / or configurations without departing from the present disclosure.

[0029] In a first processing step of forming the inner member 61 from the first blank 1, the inner locking tabs 9.1, 9.2, 10.1, 10.2 may be folded against and secured (eg adhered) to the outer sides of the respective inner panels 3, 5. Figure 2 In an exemplary embodiment, the inner locking tabs 9.1, 9.2, 10.1, 10.2 may be folded and adhered to the respective inner panels 3, 5 (e.g., by a packaging manufacturer) and then stored and / or shipped (e.g., delivered to a packer) in a flat adhered blank configuration (not shown), e.g., stacked with other similar or identical blanks.

[0030] like Figure 3 and Figure 4As shown, the upright inner member 61 can be formed (e.g., by a fold-and-bond system, a packer, etc.) from a flat adhesive blank 1 by folding the inner side panels 3, 5 along transverse fold lines 2.1, 2.3 so that they extend upwardly from the bottom panel 2, folding the inner end flaps 15, 18 and 16, 17 along respective longitudinal fold lines 3.1, 5.3 and 3.3, 5.1 at respective ends of the inner member 61, and folding the inner end panels 6, 4 along respective longitudinal fold lines 2.4, 2.2 at respective ends of the inner member 61. In the embodiment shown, the inner end flaps 15, 16, 17, 18 can be folded to extend perpendicularly to the inner panels 3, 5 between the inner panels 3, 5. In an embodiment, the first inner end panel 4 can overlap and be fixed (e.g., adhered) to the inner end flaps 16, 17 to form a first inner end wall, and the second inner end panel 6 can overlap and be fixed (e.g., adhered) to the inner end flaps 15, 18 to form a second inner end wall. In the illustrated embodiment, the bottom panel 2, the inner panels 3, 4, 5, 6, and the inner end flaps 15, 16, 17, 18 can extend at least partially around a first interior of the interior member 61 to receive items in the interior member 61. In the illustrated embodiment, the upright interior member 61 can have a first or interior opening 65 defined between the inner panels 3, 4, 5, 6 relative to the bottom panel 2 (e.g., for inserting and removing products from the interior member 17). As shown in FIG. Figure 4 As shown, the folded inner locking tabs 9.1, 9.2, 10.1, 10.2 have locking edges 13.1, 13.2, 14.1, 14.2 spaced downward from the top edge of the corresponding inner panel 3, 5. In the embodiment shown, the locking edges 13.1, 13.2, 14.1, 14.2 may face away from the inner opening 65 and toward the bottom panel 2, and may be spaced apart from the inner opening 65 and the bottom panel 2. Figure 3 As shown, the inner locking flaps 19, 20 can be folded down along the respective fold lines 21, 22 to be adjacent to the respective inner panels 3, 5. In one embodiment, the inner locking flaps 19, 20 are not connected to the outer surface of the inner panel, so that the inner locking flaps can move freely relative to the inner panel. The inner locking flap 19 is adjacent to and spaced apart from each inner locking tab 9.1, 9.2, and the inner locking flap 20 is adjacent to and spaced apart from each inner locking tab 10.1, 10.2. Figure 4 As shown, the distal edges 19.1, 19.2 of the locking flaps 19, 20 are closer to the top edge of the respective inner panel 3, 5 than the locking edges 13.1, 13.2, 14.1, 14.2 of the folded and attached inner locking tabs 9.1, 9.2, 10.1, 10.2.

[0031] The inner member 61 may be formed in other ways without departing from the present disclosure.

[0032] like Figure 5 As shown, the second blank 25 for the outer part / member 60 can have a longitudinal direction L1 and a transverse direction L2. In the embodiment shown, the second blank 25 can include a top wall or top panel 26 foldably connected to four second side walls or outer side panels 27, 28, 29, 30 along corresponding fold lines 26.1, 26.2, 26.3, 26.4 at its edges. For example, the top panel 26 can be foldably connected to the corresponding first outer side panel 27 and the second outer side panel 29 along the corresponding transverse fold lines 26.1, 26.3, and the top panel 26 can be foldably connected to the corresponding first outer side panel 27 and the second outer side panel 29 along the corresponding longitudinal fold lines 26.2, 26.4. 30. In an embodiment, each of the top wall 26 and the outer side panels 27, 28, 29, 30 can be rectangular. Any of the top panel 26 and / or the outer side panels 27, 28, 29, 30 can be omitted or can have other shapes, arrangements and / or configurations without departing from the present disclosure.

[0033] In the illustrated embodiment, the first outer side panel 27 can be foldably connected to the respective outer dust flaps or outer side end flaps 46, 47 along respective longitudinal fold lines 27.1, 27.2. Similarly, the second outer side panel 29 can be foldably connected to the respective outer dust flaps or outer side end flaps 48, 49 along respective longitudinal fold lines 29.1, 29.2. Any of the outer side end flaps 46, 47, 48, 49 and / or the outer side panels 27, 29 can be omitted or can have other shapes, arrangements and / or configurations without departing from the present disclosure.

[0034] like Figure 5As shown, the outer panels 27, 29 can be foldably connected to the respective second or outer locking tabs 35, 36 at the opposite edges of the outer panels 27, 29 along the respective transverse fold lines 31, 32. In the illustrated embodiment, each outer locking tab 35, 36 can include a respective proximal segment 35.1, 36.1 (e.g., an outer or second proximal segment) and a respective distal segment 43, 44 (e.g., an outer or second distal segment). In an embodiment, the proximal segments 35.1, 36.1 are foldably connected (e.g., directly foldably connected) to the respective outer panels 27, 29 along the respective transverse fold lines 31, 32, and are foldably connected to the respective distal segments 43, 44 along the respective transverse fold lines 41, 42 opposite to the respective transverse fold lines 31, 32. In an exemplary embodiment, each proximal segment 35.1, 36.1 may have two parts, wherein the respective first part 33, 34 is adjacent to the respective transverse fold line 31, 32 and may be rectangular (e.g., may be defined by a free edge extending in the longitudinal direction L1). In an embodiment, the second part 39, 40 is adjacent to the respective transverse fold line 41, 42 and is trapezoidal (e.g., may be defined by an inclined free edge), wherein the respective second part 39, 40 widens toward the respective first part 33, 34. In an exemplary embodiment, the distal segments 43, 44 may be rectangular and may be foldably connected to the short sides of the proximal segments 35.1, 36.1 along the transverse fold lines 41, 42. Alternatively, the segments 35.1, 43, 36.1, 44 may have any suitable shape.

[0035] In the embodiment shown, the second blank 25 may include engagement means or features 50, 51 extending in the respective outer side panels 27, 29. Figure 5 As shown, the engagement means 50, 51 can be positioned closer to the top panel 26 than to the corresponding outer locking tabs 35, 36 and can have an oval shape. In some embodiments, the engagement means 50, 51 can include corresponding weakened lines 52, 53 (e.g., cut or tear lines) that at least partially define corresponding engagement covers or cover panels 54, 55. In an exemplary embodiment, the weakened lines 52, 53 can be formed by score lines, tear lines, cut lines, or any suitable weakened lines that are staggered on the outer and inner surfaces of the outer panels 27, 29. Figure 5As shown, the joining means 50, 51 may include respective access openings 56, 57 (e.g., having a lens shape) extending along the edge of the respective weakening lines 52, 53 (e.g., near the top panel 26). Alternatively, the access openings 56, 57 may be located along any portion of the respective cover panels 54, 55 or may be omitted. In some embodiments, the cover panels 54, 55 may be removed by tearing along the weakening lines 52, 53 to form respective joining holes 51.1, 51.2 in the respective outer side panels 27, 29. In some embodiments, the joining means 50, 51 may include fold lines (not shown), wherein the respective weakening lines 52, 53 extend from the ends of the respective fold lines, so that the cover panels 54, 55 are partially removed from the respective outer side panels 27, 29 along the respective weakening lines 52, 53 and folded outwardly along the respective fold lines (not shown). Alternatively, the cover panels 54 , 55 may be removed from the blank 25 to expose the engagement openings 50 . 1 , 51 . 1 and then the outer member 60 may be formed from a second blank, or the cover panels 54 , 55 may be omitted and not included in the blank 25 .

[0036] like Figure 5 As shown, the second blank 25 may also include engagement openings 58, 59 (e.g., oval). In some embodiments, the opening 58 may extend in the proximal portion 35.1 of the first outer panel 27 and the first outer locking tab 35 (e.g., half in the outer panel 27, half in the proximal portion 35.1, symmetrically arranged relative to the transverse fold line 31). In addition, the engagement opening 59 extends in the proximal portion 36.1 of the second outer panel 29 and the second outer locking tab 36 (e.g., half in the outer panel 29, half in the proximal portion 36.1, symmetrically arranged relative to the transverse fold line 32). Any of the engagement features 50, 51, 58, 59 may be omitted or may have other shapes, arrangements and / or configurations without departing from the present disclosure. For example, the engagement feature may have any suitable shape. In another example, the cover panels 54, 55 may be omitted so that the engagement features 50, 51 are openings 50.1, 51.1 in the outer panels 27, 29. Additionally, at least partially removable panels (not shown) (e.g., similar to cover panels 54, 55) may be included in blank 25 and may be removed by tearing along weakening lines (not shown) (e.g., similar to weakening lines 52, 53) to form engagement openings 58, 59.

[0037] The blank 25 may have other shapes, arrangements, and / or configurations without departing from the present disclosure.

[0038] In the process for forming the outer member 60 ( Figure 6), the distal segments 43, 44 of the outer locking tabs 35, 36 may be folded against and fixed (e.g., glued) on the inner side of the respective proximal segments 35.1, 36.1 of the outer locking tabs 35, 36. Furthermore, the outer proximal segments 35.1, 36.1 may be folded against the inner side of the respective outer side panels 27, 29, and the distal segments 43, 44 may be fixed (e.g., glued) on the inner side of the outer side panels 27, 29. Thus, the distal segments 43, 44 may be fixed between the respective proximal segments 35.1, 36.1 and the respective outer side panels 27, 29. Alternatively, the proximal portions 33.1, 34.1 may be disposed between and fixed to the respective outer side panels 27, 29 and the respective distal portions 43, 44. In the embodiment shown, the folded outer locking tabs 35, 36 may form second or outer locking edges 45.1, 45.2 along the respective transverse fold lines 41, 42 and are positioned between the engagement means 50, 51 and the respective transverse fold lines 31, 32 ( Figure 6-8 ).like Figure 6-8 As shown, when the outer locking tabs 35, 36 are folded against the inner sides of the outer panels 27, 29, the engagement openings 58, 59 form corresponding engagement grooves or cutouts in the outer member 60. In some embodiments, the engagement grooves 58, 59 can have a semi-elliptical shape and can extend along the lower edge of the outer panels 27, 29. In an exemplary embodiment, the outer locking tabs 35, 36 can be folded and bonded to the corresponding outer panels 27, 29 (e.g., by a packaging manufacturer) and then stored and / or shipped (e.g., shipped to a packer) in a flat, bonded blank configuration (not shown), such as in a stack with other similar or identical blanks and / or with the first blank 1.

[0039] like Figure 6As shown, the upright outer member 61 can be formed from a flat, bonded blank 25 (e.g., by a fold-and-bond system, a packer, etc.) by folding the outer side panels 27, 29 along transverse fold lines 26.1, 26.3 to extend downwardly from the top panel 26, folding the outer end flaps 46, 49 and 47, 48 along respective longitudinal fold lines 27.1, 29.1 and 27.2, 29.1 at respective ends of the outer member 61, and folding the outer end panels 30, 28 along respective longitudinal fold lines 26.4, 26.2 at respective ends of the outer member 61. In the illustrated embodiment, the outer end flaps 46, 47, 48, 49 can be folded to extend between and perpendicular to the outer side panels 27, 29. In some embodiments, the first outer end panel 28 can overlap and be fixed (e.g., bonded) to the outer end flaps 47, 48 to form a first outer end wall, and the second outer end panel 30 can overlap and be fixed (e.g., bonded) to the outer end flaps 46, 49 to form a second outer end wall. Figure 6-8 As shown, the top panel 26, the outer side panels 27, 28, 29, 30 and the outer end flaps 46, 47, 48, 49 can extend at least partially around the second interior of the outer member 61, and when the carton 68 is in the closed configuration, the inner member 60 is at least partially received in the second interior of the outer member 61. In the embodiment shown, the upright outer member 61 can have a second or outer opening 62, and when the locking tabs are disengaged from each other, the inner member 60 can be moved into or out of the second interior of the outer member 61 through the second opening, as described in more detail below. Figure 6-8 As shown, the second locking edges 45.1, 45.2 may face away from the exterior opening 62 and toward the top panel 26, and may be spaced apart from the exterior opening 62 and the top panel 26. The exterior member 61 may be formed in other ways without departing from the present disclosure.

[0040] Figure 6 The components 60, 61 are shown in a separated or open configuration (e.g., such that the first opening 65 of the inner component 61 can be used to load the inner component 61 and / or remove items therefrom). In the illustrated embodiment, the second opening 62 of the outer component 49 is aligned with the first opening 65 of the inner component 61, ready for assembly of the carton 68 into a closed configuration ( Figure 7-8 ). In some embodiments, Figure 6-8The interior or other hidden portions of the components 60, 61 are shown in phantom. When the outer component 60 is moved onto the inner component 61 to assemble the carton 68 into a closed configuration, the second locking edges 45.1, 45.2 of the outer component 60 pass over the first locking edges 13.1, 13.2, 14.1, 14.2 of the inner component so that the second locking edges 45.1, 45.2 are arranged below the first locking edges 13.1, 13.2, 14.1, 14.2 ( Figure 8 ).like Figure 8 As shown, when the carton 68 is in the closed / locked configuration, the inner locking edges 13.1, 13.2, 14.1, 14.2 face away from the top panel 26 of the outer member 60 and are spaced apart from the top panel 26, while the outer locking edges 45.1, 45.2 face away from the bottom panel 2 of the inner member 61 and are spaced apart from the bottom panel 27. In some embodiments, the carton 68 can be assembled by moving the outer member 60 onto the inner member 61, moving the inner member 61 into the outer member 60, or moving both members 60, 61 simultaneously. In the present disclosure, Figure 6-8 The engagement and disengagement of locking features on one side of the carton 68 (e.g., corresponding to the inner panel 5 and the outer panel 29) are shown, the locking features including the outer locking tab 36, the outer locking edge 45.1, the engagement hole 51.1, the inner locking tabs 10.1, 10.2, the inner locking tab 20, the inner locking edges 14.1, 14.2 and the distal edge 20.1, some of which may be shown in phantom in one or more views. Figure 6-8 The locking features on the opposite sides of the carton 68 (e.g., corresponding to the inner panel 3 and the outer panel 27) are not shown in detail, but the locking features on the opposite sides may include an outer locking tab 35, an outer locking edge 45.2, an engagement hole 50.1, an inner locking tab 9.1, 9.2, an inner locking tab 19, an inner locking edge 13.1, 13.2, and a distal edge 19.1. The opposite side locking features not shown may be connected to the outer locking tab 35, an outer locking edge 45.2, an engagement hole 50.1, an inner locking tab 9.1, 9.2, an inner locking tab 19, an inner locking edge 13.1, 13.2, and a distal edge 19.1. Figure 6-8 68 and can be operated in the same manner as described herein. Alternatively, the locking features on the opposite sides can be configured in other ways without departing from the present disclosure. In addition, the locking features on both sides of the carton 68 can be engaged and / or disengaged in a similar manner as described herein, wherein an audible locking sound is produced by the internal locking tabs 19, 20 on both sides of the carton 68 without departing from the present disclosure.

[0041] In the illustrated embodiment, the inner locking tabs 19, 20 are movable relative to the respective inner panels 3, 5 of the inner member 61 to produce an audible sound when the inner member 61 is positioned in the locked position of the carton 68, i.e., the inner member is received in the outer member 60. The locking tabs 19, 20 are spaced apart from the adjacent locking tabs 9.1, 9.2, 10.1, 10.2 connected to the respective inner panels 3, 5. Figure 7 and 8 As shown, when the inner member 61 is received in the outer member 60, the inner locking tabs 19, 20 are pressed inwardly by the corresponding outer locking tabs 35, 36 as the inner member is received in the outer member. As the inner member 61 is further inserted into the outer member 60, the distal edges 19.1, 20.1 of the inner locking tabs 19, 20 pass over the outer locking edges 45.1, 45.2, which causes the inner locking tabs 19, 20 to press against and contact the outer side panels 27, 29 of the outer member 60 when the inner member is fully inserted into the outer member. The foldable connection of the inner locking tabs 19, 20 at the fold lines 21, 22 biases the inner locking tabs 19, 20 outwardly relative to the inner side panels 3, 5. The biasing of the inner locking tabs 19, 20 results in contact with the outer side panels 27, 29 and produces an audible "click" sound, which indicates that the carton 68 has been positioned in the locked position, wherein the locking edges 13.1, 13.2, 14.1, 14.2 of the locking tabs 9.1, 9.2, 10.1, 10.2 and the distal edges 19.1, 20.1 of the inner locking tabs 19, 20 are located above the outer locking edges 45.1, 45.2 of the outer locking tabs 35, 36. When the inner member 61 is fully inserted into the outer member 60, the inner locking tabs 19, 20 pop outward, contact the outer side walls 27, 29 and produce an audible sound indicating that the carton 68 is locked.

[0042] In addition, when the outer member 60 and the inner member 61 are pushed together, the inner locking tabs 19, 20 will produce a clear and perceptible sound, clearly indicating to the user that the carton 68 is locked. This sound may be referred to as a locking sound in the present application, which may be a click or a tap. The locking sound is caused by the inner locking tabs 19, 20 contacting the inner surface of the outer panel when the inner member 61 is received in the outer member 60. When the inner locking tabs 19, 20 no longer contact the outer locking tabs 35, 36, there is a gap between the inner locking tabs 19, 20 and the corresponding outer side walls 27, 29. The biasing force of each inner locking tab 19, 20 moves the inner locking tab away from the inner side panels 3, 5 into the gap between the inner locking tabs 19, 20 and the outer side walls 27, 29, and contacts the outer side walls, thereby producing an audible locking sound.

[0043] In the illustrated embodiment, the carton 68 can be locked in its closed configuration (e.g., due to the position of the second locking edges 45.1, 45.2 below the first locking edges 13.1, 13.2, 14.1, 14.2). For example, the second locking edges 45.1, 45.2 can face the first locking edges 13.1, 13.2, 14.1, 14.2, so that attempting to move the members 60, 61 relative to each other will cause the first locking edges 13.1, 13.2, 14.1, 14.2 and the corresponding outer locking edges 45.1, 45.2 to engage (e.g., contact, abut, interact, etc.). In some embodiments, the abutment of the first locking edges 13.1, 13.2, 14.1, 14.2 with the corresponding second locking edges 45.1, 45.2 can limit or prevent relative movement between the members 60, 61 to limit or prevent undesirable withdrawal of the inner member 61 from the opening 62 of the outer member 60. Thus, in some embodiments, the inner locking tabs 9.1, 9.2, 10.1, 10.2 may engage with respective outer locking tabs 35, 36 (e.g., along respective locking edges 13.1, 13.2, 14.1, 14.2 and 45.1, 45.2) such that the locking tabs 9.1, 9.2, 10.1, 10.2 cooperate to limit movement of the inner member 61 relative to the outer member 60. In addition, the distal edges 19.1, 20.1 of the inner locking tabs 19, 20 may also interfere / contact the second locking edge 45.1 to prevent movement of the inner member 61 relative to the outer member 60 in the locked position of the carton 68. The carton 55 may be formed and / or erected in other ways without departing from the present disclosure.

[0044] In an exemplary embodiment, the carton 68 can be manipulated to overcome the locking engagement of the inner locking tabs 9.1, 9.2, 10.1, 10.2 and the inner locking tabs 19, 20 with the outer locking tabs 35, 36, so that the inner member 61 can be moved from a first (e.g., closed or locked) position (e.g., wherein the inner member 61 is partially or completely contained within the outer member 60 and the first opening 65 is covered by the outer member 60) to a second (e.g., open) position (e.g., wherein the inner member 61 is removed from the outer member 60 through the opening 62 so that the first opening 65 is accessible). For example, the covers 54, 55 of the engagement devices 50, 51 are separated from the respective outer side panels 27, 29 along the respective weakened lines 52, 53 (e.g., by grasping the covers 54, 55 at the access openings 56, 57). In some embodiments, removing the covers 54, 55 can provide first opening protection for the carton 68. In the illustrated embodiment, removal of the covers 54, 55 may form engagement holes 51.1, 51.2 ( Figure 6), so that the inner locking tabs 9.1, 9.2, 10.1, 10.3 of the inner member 61 and the inner locking wings 19, 20 are accessible through the openings formed by the corresponding engagement means 50, 51 in the outer member 60. In the illustrated embodiment, the user can grasp the engagement holes 50.1, 51.1 formed by the engagement means 50, 51 (for example, with the thumb and index finger of one hand) and press the inner panels 3, 5, the inner locking tabs 9.1, 9.2, 10.1, 10.2 and / or the inner locking wings 19, 20 inwardly, causing the first locking edges 13.1, 13.2, 14.1, 14.2 and / or the distal edges 19.1, 20.1 to move inwardly and away from the second locking edges 45.1, 45.2 (no longer aligned with them). When the inner locking tabs 9.1, 9.2, 10.1, 10.2 and the inner locking tabs 19, 20 of the inner member 61 are pressed inwardly in this manner, the second locking edges 45.1, 45.2 of the outer member 60 are no longer blocked by the first locking edges 13.1, 13.2, 14.1, 14.2 and / or the distal edges 19.1, 19.2 of the inner member 17. In one embodiment, the central portion of the inner panels 3, 5 can be pressed inwardly through the engagement holes 50.1, 51.1 by a sufficient amount so that the first locking edges 13.1, 13.2, 14.1, 14.2 and the distal edges 19.1, 19.2 are disengaged from the second locking edges 45.1, 45.2 and the inner member 61 can move freely relative to the outer member 60.

[0045] The user may grasp the inner member 61 through the engagement notches 58, 59 in the outer member 60 (e.g., with the thumb and index finger of the other hand) while pressing the inner side panels 3, 5 inwardly and engaging the inner locking tabs 9.1, 9.2, 10.1, 10.2 and the inner locking flaps 19, 20 through the openings formed by the engagement means 50, 51. The user may pull the members 60, 61 apart with both hands while pressing the side panels 3, 5 inwardly through the openings formed in the outer member 60 by the engagement means 50, 51, thereby causing the inner locking flaps 19, 20 and the inner locking tabs 9.1, 9.2, 10.1, 10.2 to disengage from the locking edges 45.1, 45.2, and pulling the inner member 61 through the engagement notches 58, 59 in the outer member 60. In some embodiments, it may be difficult or impossible for a child to perform the unlocking and opening operations due to the size and / or dexterity limitations of their hands.

[0046] In the illustrated embodiment, once the members 60, 61 are separated (e.g., similar to Figure 6), the opening 65 of the inner member 61 is accessible for removing or adding items. According to the assembly and unlocking / separation operations described above, the carton 68 can be reclosed and / or reopened. In some embodiments, once the inner member 61 is fully inserted into the outer member 60, the reclosed carton 68 is again protected from undesired opening (e.g., by a child) by the locking engagement of the inner locking tabs 9.1, 9.2, 10.1, 10.2 with the corresponding outer locking tabs 35, 36. When the carton 68 is reclosed, the inner locking tabs 19, 20 emit an audible locking sound in the same manner as the initial closing and locking of the carton 68 described above.

[0047] In an exemplary embodiment, the shortest distance between the engagement features 50, 51 and / or the engagement grooves 58, 59 along the outside of the carton 68 is designed to make it difficult or impossible for a child (e.g., a child under the age of three, four, five, six, etc.) to unlock the carton 68, and difficult or impossible to pull the outer member 60 and the inner member 61 apart in the locked configuration. In some embodiments, this size design is based on the average body measurements of children of the corresponding age group, regardless of gender, in the European Union or North America, depending on the intended use area of ​​the outward-turning carton. In some examples, the distance between the outer sides of the second side wall can be about 50 to about 120 mm, about 70 to about 100 mm, about 60 to about 90 mm, about 80 to about 90 mm, or about 70 to about 80 mm. This helps ensure that a child's hand cannot contact all the engagement holes at the same time to unlock the folding carton, while an adult (e.g., a person who may have larger hands) can contact the locking features to unlock and open the carton 68.

[0048] According to the carton 68 of the present disclosure, when the inner member 61 is moved into the outer member 60, the inner locking tabs 9.1, 9.2, 10.1, 10.2 and the inner locking tabs 19, 20 and the outer locking tabs 35, 36 form an interlock. This is because the inner locking edges 13.1, 13.2, 14.1, 14.2 and the distal edges 19.1, 19.2 can abut against the outer locking edges 45.1, 45.2, thereby preventing the inner member 61 from being pulled out of the outer member 60. For example, pulling the inner member 61 out of the outer member 60 may, for example, require releasing the interlock between the outer part and the inner part. To do this, the user can use the thumb and index finger of one hand to engage the engagement opening of the access features 50, 51 and compress the inner panels 3, 5 inwardly to engage the inner locking tabs 9.1, 9.2, 10.1, 10.2 and the inner locking tabs 19, 20 through the opening formed by the engagement means 50, 51 so that the outer locking edges 45.1, 45.2 no longer block the path of the inner locking edges 13.1, 13.2, 14.1, 14.2 and the distal edges 19.1, 20.1. With the thumb and index finger of the other hand, the user can grasp a portion of the inner member 61 (e.g., along or near the bottom panel 2) through the second engagement opening / recess 58, 59 and pull the inner member 61 and the outer member 60 apart. In the process, the inner locking tabs 19, 20 and the inner locking tabs 9.1, 9.2, 10.1, 10.2 slide over the user's thumb and index finger of the engagement hole of the engagement access feature 50, 51, and slightly compress the inner locking tabs 19, 20 and the inner locking tabs 9.1, 9.2, 10.1, 10.2. By designing the carton 68 size so that children cannot touch the engagement opening of the access feature 50, 51 in the described manner due to their relatively small hands, it is possible to prevent or make it difficult for children to unlock. Unlocking may require a certain understanding of the locking function, which is usually not formed in children under the age of six, for example. Therefore, children can be prevented from unlocking the carton 68 of the present disclosure, thereby protecting them from the relevant dangers. In addition, the carton 68 can also prevent accidental opening, which may occur when flipping a carton that does not include a locking feature, for example, if the outer member is lifted without supporting the inner member, so that the inner member may slide out of the outer member without the locking feature.

[0049] In an exemplary embodiment, tolerances may exist in the manufacturing process of the carton 68, for example, when the packager forms the components 60, 61 from flat, bonded blanks 1, 25. These tolerances may cause small variations in the relative sizes of the components 60, 61. However, the two-layer thickness of the inner locking tabs 9.1, 9.2, 10.1, 10.2 and the outer locking tabs 45.1, 45.2 (for example, when their respective proximal and distal portions are in overlapping relationship) can help compensate for tolerances and variations that may occur during blank production and erection and bonding of the inner and / or outer components. This is beneficial for ensuring that the carton can still be securely locked in the presence of tolerances.

[0050] According to any embodiment of the present disclosure, the blank can be made of coated paperboard and similar materials, for example. For example, the inside and / or outside of the blank can be coated with a clay coating. Products, advertisements, price codes and other information or images can then be printed on the clay coating. A layer of varnish can then be applied to the blank to protect the information printed on the blank. The blank can also be coated with a moisture barrier, for example, on one or both sides. According to the above embodiments, the blank can be made of paperboard with a greater thickness, making it heavier and harder than ordinary paper. The blank can also be made of other materials, such as paperboard, cardboard or any other material with appropriate properties to make the carton have at least approximately the function described herein. The blank can also be laminated or coated with one or more layers of laminar material on a selected panel or panel section.

[0051] According to exemplary embodiments of the present disclosure, a fold line can be any substantially linear, but not necessarily straight, form of weakening that facilitates folding therealong. Specifically, but not limiting the scope of the present disclosure, fold lines include: indentation lines, such as lines formed with a blunt indentation knife or similar tool, which form crushed or depressed portions in the material along the desired line of weakness; cuts cut into the material along the desired line of weakness, and / or a series of cuts cut into and / or completely penetrate the material along the desired line of weakness; and various combinations of these features. Where cutting is used to form a fold line, the cutting is typically not so extensive that a reasonable user would mistakenly perceive the fold line as a tear line.

[0052] For example, a tear line may include: a slit that cuts into the material along a desired line of weakness, and / or a series of spaced slits that cut into and / or completely penetrate the material along a desired line of weakness, or various combinations of these features. More specifically, one type of tear line is in the form of a series of spaced slits that completely penetrate the material, with adjacent slits slightly spaced apart so as to define gaps (e.g., small, somewhat bridge-like portions of the material) between adjacent gaps, typically used to temporarily connect the material across the tear line. During tearing along the tear line, these gaps break. The gaps typically account for a relatively small percentage of the tear line, or the gaps in the tear line may be omitted, making the tear line a continuous cut line. That is, within the scope of the present disclosure, each tear line may be replaced by a continuous slit or the like. For example, a cut line may be a continuous slit or may be wider than a slit without departing from the scope of the present disclosure.

[0053] The above embodiments may be described as having one or more panels that are glued together during erection of the carton embodiment. The term "glue" is intended to encompass all commonly used adhesives for securing carton panels in place.

[0054] The above disclosed description shows and describes various embodiments. Since various changes can be made to the above structure without departing from the scope of the disclosure, it is intended that all content included in the above description or shown in the accompanying drawings be interpreted as illustrative rather than restrictive. In addition, the scope of the present disclosure covers various modifications, combinations, changes, etc. of the above embodiments. In addition, only selected embodiments are disclosed, but various other combinations, modifications, and environments are also included within the scope of the disclosure based on the above teachings and / or the skills or knowledge in the relevant technical field. In addition, certain features and characteristics of each embodiment can be selectively interchanged and applied to other disclosed embodiments that are shown and not shown.
