Description

CARTON WITH REINFORCED HAND STRUCTURE TECHNICAL FIELD OF THE INVENTION The invention is concerned with cardboard boxes and more particularly with cardboard boxes that have a reinforced handle structure that improves the integrity and appearance of the carton.

BACKGROUND OF THE INVENTION The handles are useful in cardboard boxes as means for transporting cardboard boxes. A problem in flexible material cartons where a handle formed in a panel of the carton is that forces of substantial stress are commonly concentrated in the handle or undesirable portions of the panel in which the handle resides. It can be appreciated that it would be desirable to have a handle structure for a cardboard box of flexible material that does not impart significant forces on undesirable portions of the handle or panel in which the handle resides. It is often desirable to have a cardboard box having walls that are as aesthetically pleasing as possible to the potential buyers of the package formed by the carton. Thus, it can be appreciated that it would be desirable to have a cardboard box with a handle structure that works with a wall or panel of the cardboard box that is also aesthetically pleasing.

BRIEF DESCRIPTION OF THE INVENTION According to a preferred embodiment of the invention, a handle structure for a carton is formed within a panel having opposite side edges and opposite end edges that intersect to form corners of the handle panel , the structure of the handle. A strip or band element is integrally joined with the handle panel and extends between the edges of the end. Opposed band edges are substantially separated from the handle panel. The band element includes a substantially centrally disposed region where opposite center edge band segments of the opposite band edges are substantially parallel to and moderate the opposite side edges. A dividing line segment is disposed proximate to each of the corners of the handle panel extending from a first point of the proximal end to an associated corner of the corners to a second end point near the centrally disposed region of the band element, such that when a force that is substantially normal to a plane in which the handle panels lie is exerted on the centrally disposed region, the strip member is flexed substantially out of the plane from a nearby biased or biased position. to the plane.

Other advantages or objects of the present invention will be apparent from the following description, the accompanying drawings and the appended claims.

Figure 2 is an isometric illustration of the carton of Figure 1 with the handle element raised upwards. Fig. 3 is a plan view of a preform for forming the cardboard box with the handle structure shown in Fig. 1. Fig. 4 is a view of a preform for forming a cardboard box having a handle structure. according to an alternative preferred embodiment of the invention. Figure 5 is an isometric illustration of a cardboard box having a handle structure according to an alternative preferred embodiment of the invention formed from the preform of Figure 4.

DETAILED DESCRIPTION OF THE PREFERRED MODALITIES In all the drawings, the same reference numerals are used to denote the same or similar characteristics of the invention. For convenience of understanding, reference can be made to Figures 1, 2 and 3 simultaneously. Figures 1 and 2 illustrate a cardboard box 10 having a structure of handle according to a preferred embodiment of the invention. Figure 3 illustrates the preform 12 from which the cardboard box of Figures 1 and 2 is formed. Figure 2 illustrates the transverse alignment of the cans C with respect to the handle structure of the carton 10 according to a preferred embodiment of the invention. Figure 2 also illustrates the manner in which the upper wall of the carton 10 including its handle structure arches upwardly when a force F is applied to lift the band element 14. The environment of the handle structure of the invention is a cardboard box 10 which forms a closure or envelope from a series of interconnected panels. In figure 3, the main attachment panels 20, 22, 24, 26 and 28 that form a tubular structure when the most extreme panels 20, 28 are joined are seen more clearly. The most extreme panels 20, 28 of the preform 12 form the upper wall or panel of the cardboard box 12 containing the handle structure. For convenience of explanation, each portion of the top panel 20, 28 is further described in segments. Each half panel has a strip or band element 46, 44 with a tapered region 30, 38 intermediate the end regions. The remaining portion 40, 42 of the top panel lies along a side edge of the top panel. Fins or flaps 80 are attached to the edges of the end of the top panel. Each flap or flap forms at least a portion of an end wall in the erect carton. In the erect cardboard box 10, the strip elements 46, 44 overlap to a certain extent and the tapered regions 30, 38 overlap fully to produce a substantially reinforced handle. In the end regions of the strip handle elements 46, 44 a ribbon extends diagonally from the apex of a side edge and an edge of the end of the panel. The elongated ribbons 54 are defined by an array spaced apart from a perforated line 57 extending diagonally from the aforementioned apex and a perforation line 56 that lies between the perforated line and the edge of the end of the panel 20, 28. The intersection of the perforation line 56 and the perforated line 57 improves the effectiveness of the invention.

A connecting element 70 joins the strip element 46, 44 and a portion of the region 42, 40 of the top panel adjacent the strip element 46, 44. The stress on the end region of the handle structure is directed more evenly towards the ends of the handle structure and the cardboard box by means of the coincidence of an edge 72 (which appears as a line cut in the preform 12) of the strip element 46, 44 with the perforation line 56 of the tape elongated A further improvement of the operation of the handle structure is obtained by terminating the edge 72 on the connecting tab 70. Optionally, the end regions of the upper panel, which coincide with the end regions of the handle structure, can having an intermediate band panel 50 defined by a curved or arched perforation line 58, which in the preform 12, coincides with the perforated lines 57 of the elongated tapes of the handle structure. Another pair of intermediate tape panels 60 can also be formed on the opposite side of the carton. The strip element 44, 46 provides a handle that directs the stress towards the ends of the carton. The characteristics of the handle structure that are described above cause the strip or band element 30, 38 and other elements on the upper panel of the carton to flex or bow in a predetermined manner projecting outwardly when the carton 10 is raised F. The structure of the elongated ribbons 54 causes the top panel 20, 28 to be arched concave in a graduated, upwardly inward configuration when the carton is lifted by a force as illustrated in Fig. 2. The tapered strip element 30, 38 provides a convenient, reliable handle. The connecting tabs 70 interconnect the strip or band element 46, 44 and the adjacent upper panel regions 42, 40. This interconnection causes the top panel 20, 28 to maintain a more contiguous configuration when the carton is lifted. The lateral regions 42, 40 of the upper panel have a tendency to flex away from the strip or band element. The connecting tabs inhibit such movement and promote a more pleasant appearance and greater integrity to the top panel of the carton. The intermediate belt panels 50, 60 allow the corners of the carton 10 to be pulled harder when the cans C or similar articles are aligned transversely in the carton with respect to the longitudinal dimension of the carton and in the top panel as shown in Figure 2. The structure of the invention provides a handle that is reinforced and directs the effort away from the handle itself to the ends of the carton while aiding the carton to maintain an aesthetically pleasing appearance and greater integrity when lifted. Referring now now to Figure 4 and Figure 5, there is shown a carton having an alternative preferred embodiment of handle structure according to the teachings of the invention. In Figures 4 and 5, features corresponding to similar characteristics of the preferred embodiment of the invention discussed above and illustrated in Figures 1-3 are denoted by the same reference numbers but with the series "100". For example, panel 24 in the first embodiment is denoted 124 in the alternative preferred embodiment. In the alternative preferred embodiment of Figures 4 and 5 a first corner tape 200 is formed at each corner of the top wall in which the handle structure is formed by a perforated line 191 ("perforated" as it consists of cut segments) alternating and perforated segments) and a first corner scoring line 191 extending convergently from the corner of the top wall or panel towards the edge of the end of the strip or band element 144. The various "tapes" in this alternative embodiment are also for convenience of explanation sometimes alternatively referred to herein as "seals" and "pleats". The perforated line 190 intersects the proximal apex of the top wall where a side edge and an edge of the end of the top wall intersect. The first corner score line 191 is disposed intermediate the perforated line 190 and the lateral edge of the top wall. A second corner slagging line 192 is disposed adjacent to the first corner slagging line forming another belt or gasket. A diagonal cutting line 193 is disposed at each corner of the side wall 122, 126 adjacent to the upper wall in alignment coincident with the first corner slagging line 191. The cutting line 172 defining each edge of the ends of the strip element can have many orientations but in the preferred alternative embodiment illustrated it is optimally arranged in longitudinal alignment substantially parallel with the strip element and the side edges of the top wall. The tabs 170 that serve as loop joints (tapes / pleats) are formed by scoring lines of the tongue 194, 195. Although the tongue slagging lines may have many different alignments with respect to each other, in the alternative embodiment Preferred illustrated are non-parallel. One of the tongue slagging lines 195 is directed towards the opening of the hole for the hand. Each tab 170 is further defined by the cutting lines 172 and 196 which define the edges of the strip element. Referring now in particular to Figure 5, the particular arrangement of elements and handle structure of the alternate preferred embodiment described alternatively and illustrated in Figure 5 causes the top wall of the carton to be deformed in a controlled manner and direct the effort in a predetermined way. With reference momentarily in particular to Figure 4, each cutting line 172, 176 that separates the structure of the strip element from the rest of the upper wall and tab 170, respectively, is interrupted by a notch element that provides a link between these elements . As the strip element is lifted F, the notch elements cause the strip member or band 144 and the tabs 170 to be separated from each other and from the top wall in a predetermined manner, such that the strip member it is arcuate outwards and the joints 200, 202 and 204 are offset angularly one with respect to the other. Optimally, the first seal 200 is displaced to an inward condition of the strip member arched outwardly. The lifting force exerted on the cardboard box causes deformation that produces a union between the diagonal cutting lines and the first slagging lines. In turn, this deformation causes the first gasket 200 to extend over the edge of the side wall of the carton. The arrangement of elements described directs the effort to the corners of the cardboard box. Further, when articles such as cans C are aligned in the carton, the cans enclosed in the corners of the carton adjacent to the first joints act as a "via" or brace element. In an optimal mode, as the strip element is lifted, the set of notches that join the strip element 144 and the tabs 170 before the set of notches connecting the strip element next to the tab 170 and the strip rest of the upper wall. The primary elements of the handle structure of the present invention are the strip or band element 30/38 and 130/138, separated from the handle panel 44/46 and 144/146 and are referred to in this portion of the description as segments of separation line 72 and 172. Each segment line segment extends between a point that is close to a corner of the handle panel and a second point that is close to a region centrally disposed of the strip element. This arrangement produces a spring-like relationship between the strip or band element and the handle panel such that when a force F is exerted on a region centrally disposed of the handle of the strip in a direction substantially perpendicular to a plane (or notional plane) which lies the handle panel, in the strip element it flexes out of the plane from a predetermined or polarized position close to the plane as illustrated in figures 2 and 5. The arrangement of the element just described essentially creates a tape inclusive of the fold 70 and 170 that joins the end regions of the strip element when the rest of the handle panel. The stresses due to the weight of the carton (and the displacement force F used to lift and suspend the carton) are focused from the ends of the strip or band element towards the corners and end walls and sidewall regions adjacent to the cardboard box instead of undesirable regions of the handle panel and centrally disposed region of the strip or band element that are likely to tear and fail. The substantial separation of the centrally disposed region of the strip member from the plane of the handle panel helps facilitate the dissipation of stresses in the manner described above. The separation line segments may be arranged in several optimal arrangements such as parallel to the side edges of the handle panel and diverging from the side panels as the line segment extends to the edges of the end of the handle panel . In a cardboard box in which cylindrical items such as cans C are packed, the end point of the separation line segment that is closest to the corner finishes optimally at near a tangent line P where the can end of the packaged can arrangement is tangent to the handle panel. Frangible elements or notch elements 74, 76 and 174, 176 are optimally arranged by joining the tape including the pleats 70 and 170 and the strip element and joining the segments of the separation line 72 and 172 respectively, such that a force that is substantially perpendicular to a notional plane of the The handle panel is exerted on the centrally disposed region of the strip element, the strip element flexes outwardly from the handle panel in a coordinated sequence beginning nearer to the region centrally disposed and advancing towards the respective edges of the opposite edges. Joints 54 and 200 described above serve the same function as previously described. The joints extend from the point of the end closest to the corner of the corner itself. The joints can be formed from a pair of slagging lines, a pair of perforated lines or a combination of a mismatched pair of a slagging line and a perforated line. Modifications may be made to the foregoing without departing from the scope and spirit of the claimed invention.
