Carton With Hand-Receiving Tear Initiation Feature
A package includes a plurality of upright bottles arranged in at least one row, and a carton for enclosing the bottles. The carton includes a top wall disposed over tops of the bottles and at least one cushioning flap hingedly connected to the top wall along a fold line. A portion of the cushioning flap is defined at least in part by a tear line such that the cushioning flap is separable from the top wall along the tear line and is inwardly foldable along the fold line so as to provide in the top wall an aperture for receiving fingers of a user's hand and a cushioned edge that can be gripped for engaging the carton. The cushioning flap is concavely contoured along the tear line such that the cushioning flap can be folded inwardly with a portion of the cushioning flap passing over at least one of the bottles without being obstructed by said at least one bottle and with extended distal ends of the cushioning flap passing on either side of said at least one bottle.
This application claims priority to U.S. Provisional Application No. 60/827,197, filed Sep. 27, 2006, the entirety of which is incorporated herein by reference.
TECHNICAL FIELDThis invention relates generally to cartons and, more specifically, to cartons having an improved tear initiation feature.
BACKGROUND OF THE INVENTIONA tool box style carton typically includes two detachable portions which are separable to define a strap handle for carrying the carton. The detachable portions are relatively large in order to expose all or most of the articles in the carton, while preserving the ability to transport the articles in the opened carton by means of the strap handle. Because the detachable portions are so large, the severance lines that define the detachable portions typically should not be easily breakable in order to prevent the tool box carton from being inadvertently opened. Thus, it would be desirable for the tool box style carton to include a tear initiation feature to facilitate separation of the detachable portions from the tool box carton.
One problem with the known tear initiation features is that they are difficult to operate and do not allow a user to get a firm grip of the detachable portion to steer and control the tearing of the severance lines. The tear initiation features are otherwise uncomfortable or difficult to use to remove the detachable portions.
Since the tool box style carton is commonly used to carry a full load of glass bottles after the detachable portions have been removed, it is important that the strap which is defined by removing the detachable portions from the tool box carton be strong and comfortable for a user to grasp as well. Thus, it is also desirable to cushion the user's hand from the raw edges that remain after formation of the strap handle.
Therefore, a heretofore unaddressed need exists in the industry to address the aforementioned deficiencies and inadequacies. What is needed is a tear initiation feature that is ergonomically designed to be engaged by a user's hand to facilitate controlled separation of a detachable portion. Further, it is desired that removal of the detachable portion defines an ergonomic strap handle.
SUMMARY OF THE INVENTIONThe various embodiments of the present invention overcome the shortcomings of the prior art by providing a carton for enclosing and transporting a plurality of articles that are arranged in rows, such as glass or plastic bottles having elongated necks. The carton includes an improved tear initiation feature for controlling the separation of one or more large detachable portions of the carton. Each of the detachable portions is defined by a substantially continuous severance line. The detachable portion can be separated from the carton along the severance line to define an opening for exposing articles in the carton.
The tear initiation feature includes a cushioning flap that is hingedly connected to the detachable portion of the carton along a fold line. The cushioning flap is further defined by a segment of the severance line that defines the detachable portion and by severance lines that extend between the segment of the severance line and the fold line. Thereby, the cushioning flap is separable along the severance lines and foldable along the fold line to provide an aperture for receiving the fingers of a user's hand and a cushioned edge that can be gripped or engaged to control separation of the detachable portion.
A portion of the segment of the severance line is contoured and the cushioning flap is dimensioned and positioned in accordance with the relative positions of an arrangement of articles. In the exemplary embodiment, the cushioning flap is dimensioned and positioned to fold inwardly into the carton so as to be disposed in the space defined by the sides or necks of articles between a first row and a second row. The contoured portion of the segment of the severance line forks from a proximal point that is located substantially between two centermost bottles in adjacent rows to distal points that are located between bottles in the second row, for example, on either side of the center bottle in the second row. Thereby, the bottles in the second row do not obstruct the cushioning flaps as it is folded inwardly. Further, in certain embodiments that include multiple detachable portions that define a strap handle, the contoured portion of the segment of the severance line for each detachable portion defines a handle flap to provide a cushioned edge for the strap handle.
The foregoing has broadly outlined some of the aspects and features of the present invention, which should be construed to be merely illustrative of various potential applications of the invention. Other beneficial results can be obtained by applying the disclosed information in a different manner or by combining various aspects of the disclosed embodiments. Accordingly, other aspects and a more comprehensive understanding of the invention may be obtained by referring to the detailed description of the exemplary embodiments taken in conjunction with the accompanying drawings, in addition to the scope of the invention defined by the claims.

Generally described, the carton includes a substantially continuous severance line that defines a detachable portion of the carton and a tear initiation feature that facilitates separating the detachable portion of the carton from the rest of the carton along the severance line, as described in further detail below.
Referring to the exemplary embodiment illustrated in
As used herein, the terms “fold line” and “severance line” refer to all manner of printed lines indicating optimal fold or cut locations, frangible or otherwise weakened lines, perforations, a line of perforations, a line of short slits, a line of half-cuts, a single half-cut, a cut line, scored lines, slits, any combination thereof, and the like.
Referring to
The blank 100 includes end flaps that are hingedly connected to opposite ends of each primary panel along fold lines. The end flaps can be folded and secured to form end closure structures at respective open ends of the tubular structure portion of the carton 200 and thereby to define the end walls of the carton 200. The blank 100 is substantially symmetric such that the end flaps that are hingedly connected to opposite ends of each primary panel are substantially similar. In addition, certain other elements of the blank 100 are substantially similar. Accordingly, the end closure structures of the carton 200 are substantially identical and like references have been used with a suffix “a” or “b” affixed to distinguish one end of the carton from the other. Thus, the description of an element or group of elements having a suffix “a” is suitable for a like-numbered element or group of elements having a suffix “b”. In certain instances, for clarity, only one of the like elements is described unless a description of the other or both of the like elements is useful for understanding the invention.
A first side end flap 130a is hingedly connected to first side panel 110 along fold line 140a, a top end flap 132a is hingedly connected to top panel 112 along fold line 142a, a second side end flap 134a is hingedly connected to second side panel 114 along fold line 144a, and a bottom end flap 136a is hingedly connected to bottom panel 116 along fold line 146a.
The blank 100 further includes substantially continuous severance lines 150a, 150b. The severance line 150a extends from the distal end of the first side end flap 130a across the first side end flap 130a to the fold line 140a, from the fold line 140a across the first side panel 110 to the fold line 120, from the fold line 120 transversely across the top panel 112 to the fold line 122, from the fold line 122 across the second side panel 114 to the fold line 144a, and from the fold line 144a across the second side end flap 134a to the distal end of the second side end flap 134a.
A segment 152a of the severance line 150a extends partially across the top panel 112 to partially define a tear initiation feature T that facilitates breaking the severance line 150a. In the exemplary embodiment, the tear initiation feature T includes a cushioning flap 160a that is defined along its distal edge by the segment 152a and along its proximal edge by a fold line 154a that is offset from the severance line 150a. The fold line 154a hingedly connects the cushioning flap 160 to a detachable portion 250a, as will be described in detail below. The cushioning flap 160a is further defined by severance lines 156a, 158a that extend between the segment 152a of the severance line 150a and the fold line 154a. Further, in the exemplary embodiment, the cushioning flap 160a includes an extensively weakened or precut slit 166a that extends from the segment 152a of the severance line 150a toward the fold line 154a.
The segment 152a of the severance line 150a is contoured or curved to at least partially define extended distal ends 162a, 164a of the cushioning flap 160a and to at least partially define a handle flap 170a to cushion the edge of a strap handle 230 of the carton 200, as described in further detail below. In the embodiment shown, the handle flap 170a is substantially semicircular such that the segment 152a includes a section that is concave from the perspective of the handle. The handle flap 170a is further defined by a fold line 172a. In the exemplary embodiment, the fold line 172a is aligned with a substantially linear portion of the severance line 150a that extends across the top panel 112. The ends of the fold line 172a intersect the ends of the contoured portion of the segment 152a of the severance line 150a.

Erecting the carton 200 from the blank 100 may be accomplished with the folding operations as described herein. The operations can be performed by automatic erecting machinery and/or manually. The erecting process is not limited to the exemplary method described herein. Particularly, the order of the steps can be altered according to manufacturing requirements, steps may be added or omitted, and the means for securing components to one another may vary. The surfaces of sheet material may be secured together by suitable means for securing including tape, staples, interlocking folds, VELCRO®, glue or other adhesives, mechanical fasteners, chemical bonding, combinations thereof, and the like.
The blank 100 is folded along the fold line 124 such that the inside surface of the bottom panel 116 is in a face contacting arrangement with the inside surface of the second side panel 114. Glue or other adhesive is applied to the outside surface of the edge flap 118 and blank is folded along the fold line 120 such that the inside surface of the first side panel 110 is in a face contacting relationship with the inside surface of the top panel 112. Thereby, the inside surface of the first side panel 110 overlaps and is secured to the edge flap 118 and the blank 100 forms a collapsed tubular structure. For clarity, it should be noted that the outside surface of the blank 100 is shown in
The collapsed tubular structure (not shown) can be erected to form the tubular structure portion of the carton 200 by pulling the panels that are in a face contacting arrangement away from one another. Articles can be easily loaded through one or both open ends (not shown) of tubular structure portion of the carton 200. It should be understood that the exemplary carton 200 is adapted to hold a group of similarly dimensioned, preferably cylindrical articles such as bottles B.

The contoured portion Q of the segment 152a of the severance line 150a extends between the linear portions D of the segment 152a of the severance line 150a but curves or otherwise diverts to avoid being disposed over the cap C of the centermost bottle B in the second row R2. More specifically, the contoured portion Q of the segment 152a of the severance line 150a extends from the point P2 that lies above the space between the first and second rows R1, R2 of bottles B to points P1 that each lie above the spaces between two adjacent bottles B in the second row R2. In other words, the segment 152a of the severance line 150a curvingly or directly diverges or otherwise extends in different directions from the slit 166a, or from the point P1, to the points P2 that are on opposite sides of the centermost bottle B in the second row R2.
In the exemplary embodiment, the points P1 are disposed on opposite sides of the centermost bottle B in the second row R2. The points P1 are adjacent to the innermost side of the necks of bottles B in the row R2 and the point P2 is adjacent to the outermost side of the neck of the center bottle B in the row R2. Further, the contoured portion Q of the segment 152a curves or arcs toward the fold line 154a such that the fold line 172a and the contoured portion Q of the segment 152a are disposed on opposite sides of the centermost bottle B in the second row R2. In this manner, the ends of the contoured portion Q of the segment 152a extend to the strap handle 230 and the middle of the contoured portion Q of the segment bends around the cap C of the center bottle B, so that the cushioning flap defines handle flap 170a while being contoured so as to clear the cap C of the centermost bottle B as the carton 200 is opened.
The severance lines 156a, 158a extend from ends of the fold line 154a and substantially above spaces between the caps C of bottles B in the row R2 to intersect the severance line 150a at points P3. Substantially linear portions D of the segment 152a of the severance line 150a are substantially aligned with the fold line 172a so as to be disposed above the spaces between two adjacent bottles B in the second row R2. Each of the linear portions D of the segment 152a of the severance line 150a extends between points P1, P3 and defines a distal edge of the cushioning flap 160a.
Referring to
The cushioning flap 160a can be folded along the fold line 154a to be substantially perpendicular to the top wall 212 of the carton 200, as shown in
The distance L2 between the distal ends 162a, 164a of the cushioning flap 160a and the fold line 154a relates to the length of the necks of the bottles B such that, as the cushioning flap 160a is folded, the distal ends 162a, 164a avoid the base portions of the bottles B. The curved portion of the segment 152a of the severance line 150a defines the central portion of the cushioning flap 160a such that, as the cushioning flap 160a is folded along the fold line 154a, central portion of the cushioning flap 160a avoids or is otherwise not obstructed by the upper end and neck of the center bottle B in the row R2. Further described, the segment 152a of the severance line 150a is curved so as not to extend across the upper end of the center bottle B in the row R2.
As the cushioning flap 160a is folded into the carton 200, the fold line 154a provides a cushioned edge H that can be engaged by a user to pull the detachable portion 250a from the carton. The cushioned edge H is engaged and pulled to break the severance line 150a such that the detachable portion 250a can be at least partially separated from the carton 200 to provide an opening O that is defined by a substantially continuous edge E. A portion of certain of the bottles B is thereby exposed and can be dispensed through the opening O. It should be understood that the cushioned edge H is easily grasped such that the user can better control tearing of the severance line 150a to remove the detachable portion 250a.
