The panel is suspended from the other two end panels of the cardboard box, connected to each of the two opposite edges of the handle panel. Each of these two end panels is touched respectively by the upper and lower portions of the cans C located in the carton. The ribbon-shaped handle is located between the two opposite end panels of the cardboard box. The contribution of the invention to the prior art is due to the fact that the cardboard box contains a reinforcing rib shaped like an angular joint provided between each corner of the cardboard box and one adjacent end of the ribbon handle. In this case, each angular joint constituting the reinforcing rib is designed and arranged to deform when the belt handle is lifted by a load F of force directed beyond the plane of the handle panel so that the end cans C disposed adjacent to the opposite end panels and the handle panel, act as fasteners between the two end panels and allow significant lifting voltage to dissipate into the two end panels located around the upper and lower portions of the -terminal cans C.

Examples of carrying out the invention

In the drawings, the same positions are used to indicate the same or similar features of the invention.

For convenience, the description refers simultaneously to Figures 1, 2 and 3.

Figures 1 and 2 show a cardboard box 10 having a handle structure in accordance with a preferred embodiment of the invention. Figure 3 shows a seam 12 from which the cardboard box 10 of figures 1 and 2 is formed.

Figure 2 shows the correct relative positioning of the transverse cans C in relation to the handle structure according to the exemplary embodiment of the invention. Figure 2 also depicts the way that the upper wall of the cardboard box 10, together with the handle structure, is bent upwards when a lift force F is applied to the belt element of the handle 14.

The environment of the handle structure according to the invention is the cardboard box 10, which forms a sheath of a series of interconnected panels. Figure 3 clearly shows the main connecting panels

20,22,24,26 and 28, which form the hollow structure of the cardboard box 10 when at the end-. _{The side} panels 20,28 join.

The outermost panels 20, 28 of the unfolding, _5- storey 12-ply multi-ply cardboard form the upper wall or panel 20, 28 of the cardboard box 10, which contains the handle structure. For convenience of explanation, each part of the upper panel 20, 28 is hereinafter described separately. Each part or upper half 20, 28 has a ribbon element 46, 44 with a bevelled portion occupying an intermediate position relative to the end portions. The remaining lateral portion 40, 42 of the upper panel lies along the lateral edge of the upper panel 20, 28. To each upper half panel 20, 28 are provided caps 80 for attachment of the outer edges of the upper panel. Each latch 80 forms at least one portion of the wall of the upright box 10.

In the assembled cardboard box 10, the ribbon elements 44, 46 overlap to a certain extent, and the beveled portions 30, 38 completely overlap to create a substantially reinforced handle 14. In the end portions of the ribbon elements 46, 44 of the handle 14 is located along one reinforcing rib 54 extending diagonally from the common point of the top edge of the side edge and one end edge of the panel.

The extended reinforcement ribs 54 are determined by a pair of offset lateral lines, respectively, a perforated line 57 extending diagonally from the common point, and a cut line 56 lying between the perforated line and the end edge of the panels 20, 28.

There is provided one ear-shaped connecting element 70 which attaches the ribbon elements 44, 46 and a portion of the side portions 40, 42 to the upper panel of the handle 14 adjacent to the ribbon elements. The stress on the end portion of the handle 14 is more evenly directed to its ends and the cardboard box 10 by matching one edge defined by the dashed line 72 (appearing as a cut line in the corrugation 12 of multilayer cardboard) of the ribbon element 46, 44 , with the cut line 56 of the extended reinforcement rib 54. Further improvement of the function of the handle 14 is achieved by rotating the rib defined by the broken line 72 at the connecting element 70, made in the form of an ear.

Provision is made for safety or narrowing members 74, 76, which are optimally arranged as a bridge connection of the reinforcement rib 54 including the ear-shaped connecting element 70 and the belt element 44, 46, and respectively connect the segments of the broken line 72 so that, when a force perpendicular to the abstract plane of the upper panel 20, 28 of the handle 14 is exerted on a centrally located portion of the ribbon element 44,46, the ribbon element 44,46 extends outward from the upper panel 20, 28 of the handle 14 in a coordinated sequence , zap art-closest to the proximal portion and continuing to the respective portions of the opposing edges.

Optimally, the end portions of the upper panel 20, 28, which coincide with the end portions of the handle 14, have an intermediate reinforcing unit 50 formed in the panels 20, 28, defined by a curved or arcuate cut line 58, which in the unfolding 12 is of multilayer cardboard coincides with the perforated line 57 of the extended reinforcement ribs 54 of the handle structure 14. On the opposite side of the cardboard box 10, another pair of intermediate reinforcing units 60 may be formed, formed in panel 24.

The belt element 44,46 provides a handle 14 that directs the tension to the edges of the cardboard box 10. The handle structure characteristics described above cause the ribbon beveled sections 30, 38 and other elements to bend or bend on the top panel 20 , 28 of the cardboard box 10 in a surface projecting outwards in a predetermined manner when the cardboard box is lifted by force F. The structure of the extended reinforcing ribs 54 causes a concave bend in the step-like structure of the upper panel 20, 28, internally in walking when the cardboard box 10 is lifted in the direction of the applied force F, as shown in figure 2. The tapered bevel 30, 38 provides a comfortable and durable handle 14. The ear-shaped connecting elements 70 connect the belt elements 44, 46 and their adjacent lateral portions 40, 42 of the upper panel 20, 28. This coupling allows the upper panel 20, 28 to retain its continuous structure when the cardboard box 10 is lifted. The side portions 40,42 of the upper panel 20, 28 are curved, away from the belt elements 44, 46. The ear-shaped connecting element 70 retains such a curving motion and thus provides a more pleasing appearance and greater compactness of the top panel 20, 28 of the cardboard box 10.

The intermediate reinforcement units 50, 60, respectively formed in panels 20, 28, 24, allow the corners of the cardboard box 10 to come close to each other when the cans C or other similar articles are aligned therein, transversely with respect to the longitudinal the size of the cardboard box 10 and its top panel 20, 28 as shown in Figure 2.

The invention provides a support 14 that is reinforced and directs the tension, moving it away from the edges of the cardboard box 10, thereby providing an aesthetically pleasing appearance and greater compactness of the cardboard box 10 when lifted.

s

In Figures 4 and 5, which are both referenced simultaneously, a cardboard box 110 is shown which has an alternative embodiment of the handle structure 114 in accordance with the disclosure of the invention. In Figures 4 and 5, the features corresponding to similar features of the first preferred embodiment of the invention described above (Figures 1 to 3) are marked with the same positions, but in the group of figures 100, for example panel 24, in this alternative embodiment is indicated by heading 124.

In the exemplary embodiment of Figures 4 and 5, one first angular reinforcing rib 200 is formed at each corner of the upper panel 120, in which the handle 114 is formed by a perforated line 190 ("perforated" means that the line consists of alternating separate cuts and single cuts) and a first angular cut line 191 extends from the corner at the top of the top wall or panel 120 to the end edge of the ribbon member 144, merging therewith. The various "reinforcing ribs" in this alternative embodiment for convenience of explanation are sometimes referred to as "angular joints" and "folds". The perforated line 190 intersects approximately the highest portion of the upper panel 120, where one side edge and one end edge of the upper panel 120 intersect. The first angular cut line 191 is located between the perforated line 190 and the lateral edge of the upper panel 120. A second angular cut line 192 is arranged adjacent to the first angular cut line 191, forming another angular reinforcing rib 202 or an angular joint. At each corner of the side wall 122, 126 there is a diagonal section 193 adjacent to the upper panel 120 and forming a straight line with the first angular cut line 191.

An interrupted line 172 which defines each edge of the edges of the ribbon member 144, 146 and has many orientations, in this preferred alternative embodiment is arranged optimally in a parallel longitudinal direction with the ribbon member 144, 146 and the lateral edge of the upper panel 120.

Ear-shaped connecting elements 170 that serve as angular joints for the handle 114, representing reinforcing ribs or folds, are formed by cut lines 194, 195. Although the cut lines 194,195 of the ear-shaped connecting element 170 may have different mutual arrangement, in the preferred alternative exemplary embodiment that is shown, they are not parallel to each other. One of the cut lines 195 of the ear-shaped connecting member 170 is directed to the opening of the handle 114. In addition, each connecting element 170 is defined by two further broken lines 172, 196 which define the edges of the belt element 144,146.

Referring now in particular to Figure 5, the special arrangement of the handle structure members 114 of the alternative embodiment described above ensures that the upper wall or panel 120 of the cardboard box 110 deforms in a controlled manner and directs tension in the handle 114 in a predetermined direction. Turning in particular to Figure 4, it can be seen that each broken line 172,196 is separated by a narrow element 174,176 which 6 provides a connecting line between these elements. When the ribbon member 144, 146 is lifted by applying force F, the narrow x *% members 174,176 provide separation of the ribbon element 144, 146 and the ear-shaped connecting member 170 from each other and from the top panel 120 in a predetermined aS manner such that the ribbon member 144, 146 is bent outward and the angular reinforcement ribs 200, 202 and 204 are rotated angularly to one another. Optimally, the first corner rib 200 or joint is positioned inward from the curved handle member 144, 146 of the handle 114. The lift force F applied to the cardboard box 110 causes a deformation that occurs jointly between diagonal sections 193 and the first angular cuts lines 191. This deformation, in turn, enables the first angular reinforcing rib 200 to be located on the edge of the side wall 122,126 of the cardboard box 110. The arrangement of the above-described elements directs tion to the corners of the carton. Furthermore, when articles, such as cans C, are correctly positioned in one another in the cardboard box 110, adjacent to the first angular reinforcement rib 200, they act as a cross beam or a reinforcing element.

In optimal mode, when the strap element 110 is raised, the group of narrow elements 174,176 connecting the strip elements 144, 146 and the ear-shaped connecting element 170 is before the group of narrow elements 174, 176, it connects them to the rest of the upper panel 120.

The main structural elements of the handle 14, 114 of the cardboard box 10, 110 of the present invention are the tapered tapered sections 30, 38 and 130, 138, separated from the tapered members 44, 46 and 144, 146, and to which we refer this part of the description as separate broken lines 72 and 172. Each individual element of the broken line 72, 172 is located between one point which is close to the angle of the upper panel 20, 28 and 120 of the handle 14, 114, and a second point, which is close to the centrally located portion of the belt element 44, 46 and 144,146 of the handle 14,114. This arrangement of the elements creates flexibility and elongation, similar to the connection between the belt element 44,46 and 144, 146 and the handle 14, 114, so that when a force F is applied to the centrally located portion of the belt element 44, 46 and 144, 146 of the handle 14, 114 in a direction substantially perpendicular to the plane (or abstract plane) in which the upper panel 20, 28 and 120 are located for the handle 14, 114, the ribbon element 44, 46 and 144, 146 is bent outwards from the plane in an inclined position, or so-called approximately plane, as shown in n Figures 2 and 5.

The described position of the elements creates at least one reinforcing rib 54 or more 200, 202 ' 204 reinforcing ribs including an ear-shaped connecting element 70, 170 constituting a bend that connects the end portions of the ribbon element 44, 46 and 144, 146 to the rest on the top panel 20, 28 and 120.

The stress due to the weight of the cardboard box 10, 110 and the displacement force F used to lift and suspend the cardboard box 10, 110 is focused from the edges of the ribbon element 44, 46 and 144,146 to the corners and end walls forming the upper panel 20, 28 and 120 and the adjacent portions of the sidewalls or panels 22, and 122, 126 of the cardboard box 10, 110 instead of the undesirable portions of the upper panel 20, 28 and 120 for the handle 14, 114 and the centrally located portions of the strip elements 44, 46 and 144, 146 forming the handle 14, 114 most likely to break at and fall. Substantial separation of the central portion of the belt element 44, 46 and 144, 146 from the plane of the upper panel 20, 28 and 120 of the handle 14, 114 helps to facilitate the distribution of pressure as described above.

The individual broken lines 72 and 172, 196 may be arranged in several optimal positions, for example, parallel to the side edges of the upper panel 20, 28 and 120 of the handle 14,114 and extending from the side panels 22, 26 and 122, 126, with the individual broken line 72 and 172, 196 extends to the end edges of the upper panels 20, 28 and 120.

In the cardboard box 10, 110, in which cylindrical articles, such as tin cans C, are packed, the end point of the segment of the broken line 72 and 172, which is closest to the corner, usually ends at or near the tangent line T, where it forms at the end the can in the row touches the upper panel 20, 28 and 120 of the handle 14, 114.

The guarding or narrowing members 74, 76 and 174, 176 are optimally arranged as a bridge connection of the reinforcing rib 54 and 200, including the ear-shaped connecting elements 70 and 170 and the belt element 44,46 and 144, 146, and connecting the segments respectively. on the broken line 72 and 172, 196, so that when a force perpendicular to the abstract plane of the upper panel 20, 28 and 120 of the handle 14, 114 is exerted on a centrally located portion of the belt element 44, 46 and 144, 146, the belt element 44, 46 and 144, 146 is curved out of the upper panel 20, 28 and 120 of the handle 14, 114 in a coordinated sequence, beginning closest to the centrally located portion and continuing to the respective portions of opposite edges.

The angular reinforcement ribs 54 and 200 described above perform the same function as those described previously. The corner reinforcement ribs 54 and 200 are located between the end point closest to the corner and the corner itself. They may be formed from one pair of cut lines 56 and 191, one pair of perforated lines 57,190 and a combination of a mismatched pair of cut line 56, 191 and a perforated 5 line 57, 191.

The description and the exemplary embodiments illustrate the invention without departing from its scope and nature.
