A comparable pillow flap 74 can be provided along the fold line 78 with the opposite side edge of the handle panel 66 connected is. It can be seen that in the finished box the fold lines 76 and 78 preferably substantially on the side edges of the underlying reinforcing belt "S".

A variety of article receiving arrangements 81 . 81a is optionally provided to receive and / or engage an article, the arrangements 81 . 81a from the upper side panels 16 respectively. 21 punched out. The object receiving arrangements 81 . 81a are essentially identical and only one arrangement will therefore be described in more detail. It can be 1 from that the object receiving arrangement 81 a pair of article receiving wall surfaces 82 and 84 that covers the upper side panel 16 punched out and along divergent fold lines 86 respectively. 88 articulated with this are connected. The wall surfaces 82 and 84 may have a substantially triangular shape and are defined by a pair of punched lines 87 . 89 separated from the blank to the wall surfaces 82 . 84 to allow yourself to articulate around the fold lines 86 . 88 to move to define a retention opening. One of the punching lines 89 is preferably above the fold line 28 and ends with curved sections to provide some tension relief.

In other embodiments, no article receiving arrangements are provided, although to assist in guiding the tensions away from the carrying handle, die-cutting lines are provided 89 . 89a can be provided along one or more edges of the ceiling wall.

Each object reception arrangement 81 . 81a is configured to receive an outermost object from one of the rows, as shown in FIGS 2 and 4 is shown, wherein the wall surfaces 82 . 84 folded by abutting with an upper part of the article in an outward direction, which is received in the resulting retaining opening. Preferably, the configuration is for the article receiving assemblies 81a on one side of the ceiling wall 18 such that two adjacent articles A1, A2, such as the third and fourth rows, are received, and for the article receiving assemblies 81 on the other upper side wall so as to pick up items from other rows A3, A4, for example the second and fifth rows in FIG 2 ,

A variety of stress-deflecting score lines is in the top panel 18 educated. On one side of the box becomes, with the article receiving arrangements 81a located in adjacent positions, a score line 90 includes, extending from the handle panel 66 extends and along the punching line 89a ends, wherein one of the article receptacle assemblies 81a is trained; and preferably between the ends of the punching line 89a , In this embodiment, the score line includes 90 preferably two straight sections, which are at an obtuse angle to each other. Furthermore, a second score line 96 extending from the opposite end of the handle panel 66 extends and at the punching line 89a ends, one of the edges of the other article holder assembly 81a follows that from the upper side wall surface 21 is trained. In this embodiment, further, a pair of score lines 92 . 94 includes, extending from the ends of the punched lines 89a extend and converge at a point adjacent to a central portion of the opening 70 adjoins, and end at the outer edge of it.

The opposite side of the top panel further includes a plurality of stress relief score lines, however, the score lines are configured differently because the article receiving assemblies are spaced further apart. The score line 100 extends from the end of the handle panel 66 and ends at the punch line 89 the object recording device 81 , The score line 100 preferably comprises two straight sections with an obtuse angle therebetween, so that the score line 100 the punching line 89 from one of the article receiving openings 81 essentially perpendicular to it. A second score line 98 preferably extends from the fold line 88 to get to an outer edge of the opening 68 to end. Similarly, a second pair of score lines connects 99 . 101 the other object receptacle arrangement 81 with the handle panel 66 or the opening 68 ,

The shape and configuration of the score lines is not limited to those described above, and it is conceivable that other arrangements may be employed. However, each pair of adjacent score lines should be shaped to a part 102 . 104 . 106 . 108 the ceiling wall surface 18 to define that in the 3 and 4 are shown, which can bend and / or bend relative to the top wall and / or the side wall of the box, so as to transmit, divert and / or absorb lifting stresses from the handle.

Turning to the straightening up of the vehicle that goes into the 2 and 3 As can be seen, it is conceivable that the carton according to the present invention may be formed by means of a series of sequential folding and gluing steps which may be performed in a rectilinear machine, so that the carton is not required to be rotated or inverted must to complete their construction. The folding process is not limited to the folding process described below and may be modified according to particular manufacturing requirements.

In 2 the box is shown in a tubular state, from the blank 10 has been trained. The carrying handle reinforcing belt S is attached to the box and the fastening flap 24 is by adhesive or other suitable means known to the bottom wall surface 12 attached.

The box C is with its end closure structure, which are the upper end panels 40 and 40a and the lower end panels 42 and 42a includes, shown in the open state, so that the Box is loaded from one or both ends with items "A", with beverage bottles, as exemplified here, which are arranged in a single layer. The items "A" are on the bottom wall surface 12 the box 10 arranged. Such loading may be carried out by means of suitable commercially available automated packaging machinery.

Closure of the end closure structure is preferably effected in the following manner. The upper end panels 40 are folded into a closed position against the packaged items "A" by forming the gusset panel structures 50 to be folded inwards. Glue is applied to the lower end panel 42 applied and the lower end wall surface 42 is then folded up and to the upper end wall surface 40 attached.

An identical operation is performed to close the end closure structure located at the opposite end of the box. (In a preferred embodiment of the invention, the carton is loaded from one end using automated packaging machinery.) During such loading, the opposite unloaded carton end is sealed and sealed before the bottles are pushed into the carton). The box is in 3 presented in their fully erected and loaded blank.

The carrying handle assembly in the top panel 18 educated, can be more detailed in 4 to be viewed as. When the loaded carton is raised for the first time, in use a user brings his or her hand and / or fingers into one or both of the apertures 68 and 70 and grab the section of the wall surface 66 between. The user then raises the box C. The weight of the box causes lifting the handle panel 66 from the ceiling wall along the fault lines 80 separates and then the tensile stress along the score lines 90 . 92 . 94 . 96 . 98 . 100 in the direction of the object receiving arrangements 81 distracting. This effectively converts tensile stress in the handle area into tensile stress along the score lines. Thus, it will allow these parts 102 . 104 . 106 . 108 bend and / or bend the top wall between the fold lines mentioned above.

In The specific embodiment described is a specific one Position for each article receptacle assembly shown. The recording arrangements can however, adjacent to other objects within the item group can be arranged and the position of the score lines can accordingly changed which is still within the scope of the invention lies.

It it is further recognized that it is possible is, the carrying handle according to the present To use invention with a box, the beveled corners having.

Lifting the box causes the handle panel 66 in the middle area bends upwards and is supported by the two-ply reinforcing strap "S". Thus, the fracture lines may rupture to allow the handle panel 66 over the ceiling wall surface 18 protrudes upward. The curved stress relief lines 79 further help to prevent the tearing over the break line 80 to extend out. Since the cracking in the top panel is controlled, the overall tear resistance is actually improved. The carrying handle not only has improved strength, but also provides a comfortable feel to the user as he lifts and / or wears the box.

It should be readily recognized that although in the preferred Embodiment the present invention in the context of a box for packaging of bottles, the carrying handle structure as well a box for packaging two layers of bottles or with a box for packaging cans, jars or other containers or objects can be used. The containers can, as described herein, vertically or horizontally oriented.

Further, it should be appreciated that numerous handle reinforcing means may be used with the described carrying handle, other than those described herein. Instead of a single ceiling panel 18 and a reinforcing structure comprising a belt "S", an overlapping top panel of a known type may be used. In such an embodiment, the overlap between the two top panel sections forms a double-ply strip extending down to the center of the box top panel. An example of a box of this type is in US 5,427,242 described, which is incorporated herein by reference. The handle structure is formed in the overlapping top panel in the same manner as the handle structure described herein, as will be readily appreciated by those skilled in the art. In such an embodiment, the break lines are 80 trained to move along the Kan extending the overlapping portion.

It It should further be appreciated that the directional instructions used herein, such as "blanket", "bottom", "end", "side", "top", "middle" and "bottom", the respective ones wall surfaces not limited to such an orientation, but only to it serve, these wall surfaces to distinguish from each other. Any reference to an articulated Connection should not be construed as necessarily being refers to a single fold line, but rather it is conceivable that an articulated connection formed from one of the following without departing from the scope of the invention: score line, Fracture line or one, two or more fold lines.
