In this specification, the terms “lower,” “bottom,” “upper” and “top” indicate orientations determined in relation to fully erected and upright cartons.
The blank 3 has a longitudinal axis L1 and a lateral axis L2. In the first embodiment, the blank 3 comprises a top panel 10 foldably connected to a first side panel 20 at a first lateral fold line 21, a first bottom panel 30 foldably connected to the first side panel 20 at a second lateral fold line 31, a second side panel 40 foldably connected to the top panel 10 at a third lateral fold line 41, and a second bottom panel 50 foldably connected to the second side panel 40 at a fourth lateral fold line 51. In the illustrated embodiment, the blank 3 comprises three openings 22 that separate portions of the lateral fold line 21 and three openings 24 that separate portions of the lateral fold line 41. Each of the openings 22 has a respective curved edge 26 that cooperates with the lateral fold line 21 to form a first edge of top panel 10. Each of the openings 24 has a respective curved edge 28 that cooperates with the lateral fold line 41 to from a second edge of the top panel 10.
As shown in
In one embodiment, the top panel 10 has a width W1 corresponding to a minimum distance between the fold lines 21, 41 that form a respective first edge and second edge of the top panel. The handle panels 12, 14 have a maximum width W2 corresponding to the distance between the intersection of the cut 91 with the tear line 75 and the intersection of the cut 93 with the tear line 77. In one exemplary embodiment, the width W2 is less than the width W1. For example, in one embodiment, the width W1 of the top panel 10 can be at least approximately 68 mm and the width W2 of the handle panels 12, 14 can be at least about 47 mm so that the width W2 is at least approximately 70% of the width W1. Further, the width W2 can be at least approximately 30% less than the width W1. In other embodiments, the width W2 can be more than 30% less than the width W1 or the width W2 could be could be less than 70% of the width W1. In the illustrated embodiment, the handle flaps 12, 14 have a width W2 that allows less than an entire hand of a typical user (e.g., two or three fingers) to initiate folding of each of the handle flaps 12, 14. The above dimensions are exemplary of one embodiment and are not intended to limit the scope of the disclosure. The blank 3 could have other dimensions without departing from the scope of the disclosure.
In an exemplary embodiment, the fold line 13 connecting the handle flap 12 to the top panel is spaced apart from a longitudinally extending edge 96 of the blank 3, that corresponds with a first end 6 of the carton 5 formed from the blank, by a first distance D1, and the intersection of the tear lines 75, 77 with a respective lateral fold line 21, 41 is spaced apart from the edge 96 of the blank by a second distance D2. In one embodiment, the handle features are configured so that the first distance D1 is greater than the second distance D2 so that the second portions 81, 87 of the tear lines 75, 77 extend in the side panel at a location that is offset from where the handle flaps 12, 14 are grasped. In one embodiment, the distance D1 is approximately 64 mm and the distance D2 is approximately 48 mm, however, the distances D1, D2 could be greater than or less than listed herein without departing from the disclosure. Similarly, the fold line 15 is spaced apart from a longitudinally extending edge 98 of the blank 3, that corresponds with a second end 8 of the carton 5 formed from the blank, by the first distance D1, and the intersection of the tear lines 75, 77 extending from the fold line 15 with the respective lateral fold line 21, 41 is spaced apart from the edge 98 by the second distance D2.
In an exemplary method of erecting the carton 5, the blank 3 can be lowered onto the tops or caps C of containers B, such that the top panel 10 contacts the tops of the containers. The containers B can be arranged in a group (e.g., in a 2×3 arrangement) and the top panel 10 is aligned with group of containers such that edges of the top panel 10 corresponding to the fold lines 21, 41 are aligned with respective centerlines C1, C2 (
As shown in
The handle panels 12, 14 are sized to limit the number of fingers a user can place through the top panel 10. Limiting the amount of fingers inserted into the handle 7 prevents the tendency for an entire hand to be inserted into the handle which can cause uncontrolled tearing of the carton 5 and weakening of the handle.
In the embodiments of
In the second embodiment, the first top panel 110a includes the handle panels 112, 114 that are foldably connected to the top flap at fold lines 113, 115. The handle panels 112, 114 are separable from the top panel 110a by a respective tear line 117, 118. As with the first embodiment, the handle panels 112, 114 have a maximum width W2 that is less than the width W1 between respective edges of the top panel 110a and the top panel 111 formed by the overlapping arrangement of the top panels 110a, 110b. The dimensions noted above for the widths W1, W2 of the first embodiment can be the same or similar as the corresponding dimensions for the second embodiment.
In the second embodiment, the width W1 is the minimum distance between the lateral fold line 121 and a laterally extending edge 152 of the blank 103. The blank 103 of the second embodiment has openings 122, 124 in a respective side panel 120, 140 similar to the openings 22, 24 of the first embodiment. Also, the blank 103 has openings 125, 127 in a respective side panel 120, 140 for receiving a bottom portion of the containers B held in the carton 105.
The carton 105 is formed in a similar manner as the carton 5 of the previous embodiment. In one embodiment, the containers B are grouped into a 2×6 arrangement and are placed on the bottom panel 130 of the blank 103. The blank 103 is wrapped around the group of containers B so that the second top panel 110b contacts the tops or caps C of the containers B and the first top panel 110a overlaps the second top panel to form the top panel 111 of the carton 105. The first top panel 110a and second top panel 110b can be adhered together by glue or other adhesive, or the carton 105 can be secured by other mechanisms.
In the embodiment of
As with the first embodiment, the tear lines 175, 177 have features that allow controlled tearing when activating the handle 107 to strengthen the handle and prevent uncontrolled tearing. In the second embodiment, the tear lines 177 include a first portion 185 that is curved and extends from a respective end of the fold lines 113, 115 to the lateral fold line 121. A second portion 187 of the tear line 177 extends from the first portion 185 and terminates at a C-shaped cut 189 in the first side panel 120. In one embodiment, the first portion 185 is generally curved, and the second portion 187 extends in the longitudinal direction L1 of the blank 103 and is generally perpendicular to the lateral fold line 121. Similarly, the tear line 175 has a curved first portion 179 extending from the openings 171, 173 in the second top panel 110b, a second portion 181 that extends in the longitudinal direction L1 and is generally perpendicular to the lateral fold line 141. The second portion 181 terminates at a C-shaped cut 183 in the second side panel 140. In the second embodiment, the blank 103 has curved tear lines 190 extending from a respective second end of the fold lines 113, 115 in the first top panel 110a and extending to the laterally extending edge 152 of the blank. The blank 103 has curved tear lines 180 extending from a respective opening 171, 173 in the second top panel 110b and extending to a laterally extending edge 154 of the blank. The curved tear lines 190 overlap a portion of a respective first portion 179 of the tear lines 175 when the first top panel 110a and the second top panel 110b are overlapped to form the top panel 111 of the carton 105. Further, the curved tear lines 190 overlap a portion of a respective first portion 185 of the tear lines 177 when the first top panel 110a and the second top panel 110b are overlapped to form the top panel 111 of the carton 105.
In one embodiment, the blank 103 has lines of weakening 192 (e.g., fold lines) in the first top panel 110a and lines of weakening 194 (e.g., fold lines) in the second top panel 110b. The lines of weakening 192, 194 are positioned in a respective top panel 110a, 110b so that the lines of weakening 192 overlap the lines of weakening 194 when the top panel 111 is formed by overlapping the first top panel 110a over the second top panel 110b. The lines of weakening 192, 194 help facilitate formation of the handle 107 and allow the lifting portion 199 of the carton 105 to flex without tearing when the carton is grasped and lifted at the handle (
As with the previous embodiment, the carton 105 can be lifted and carried at the handle 107. When the handle 107 is activated and the carton 105 lifted, the tear lines 175, 177 are torn with the tear lines 175, 177 being arranged to prevent additional/uncontrolled tearing or weakening of the material of the carton 105 resulting in a handle 107 that is strengthened. The portion of the carton 105 between the fold lines 113 and tear lines 175, 177 extending therefrom, and the fold line 115 and the tear lines 175, 177 extending therefrom, forms the reinforced lifting portion 199 of the carton 105 that is strengthened by the configuration and controlled tearing of the features of the handle 107. In one embodiment, the lifting portion 199 comprises a portion of the top panel 110 and portions of the side panels 120, 140, but the lifting portion could be otherwise shaped, arranged, and/or configured without departing from the disclosure. Further, the handle panels 112, 114 and openings 171, 173 are sized to limit the number of fingers a user can place through the top panel 111 to activate the handle 107. Limiting the amount of fingers inserted into the handle 107 prevents the tendency for an entire hand to be inserted into the handle which can cause uncontrolled tearing of the carton 105 and weakening of the handle.
The blank according to the present disclosure can be, for example, formed from coated paperboard and similar materials. For example, the interior and/or exterior sides of the blank 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 blank may then be coated with a varnish to protect any information printed on the blank. The blank 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 blank may be constructed of paperboard of a caliper such that it is heavier and more rigid than ordinary paper. The blank 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 above. The blank can also be laminated to 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 can 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 at least 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
The foregoing description illustrates and describes various embodiments of the present disclosure. As various changes could be made in the above construction, 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 present disclosure covers various modifications, combinations, alterations, etc., of the above-described embodiments. It will be understood by those skilled in the art that while the present disclosure has been discussed above with reference to exemplary embodiments, various additions, modifications and changes can be made thereto without departing from the spirit and scope of the claims. Furthermore, certain features and characteristics of each embodiment may be selectively interchanged and applied to other illustrated and non-illustrated embodiments without departing from the scope of the disclosure.
