Description

Box with reinforced handle structure.

Technical Field of the Invention

The present invention relates to boxes and, more particularly, to boxes that have a handle structure reinforced that improves the integrity and appearance of the box.

Background of the invention

The handles are useful in the boxes as a means to his transport. A problem that appears in the material boxes flexible in which a handle is formed in a box panel is that the important tension forces are concentrated characteristically in the handle or in inconvenient parts of the panel in which the handle resides. It can be appreciated that it would be convenient have a handle structure for a flexible material box that does not impart significant forces on inconvenient parts of the handle or of the panel where the handle resides.

It is often convenient to have a box that has walls that are so attractive aesthetically as possible to potential buyers of packaging formed by the box. In this way, it can be seen that it would be convenient to have a handle structure that performs its function within a wall or a box panel that is also Aesthetically attractive

Summary of the invention

According to a preferred embodiment of the invention, a handle structure is formed for a box within a panel that has opposite side edges and edges of opposite ends that intersect to form corners of the handle panel, handle structure. A band element is attached entirely to the handle panel and extends between the edges of extreme. Opposite band edges are practically separated of the handle panel. The band element includes an arranged area substantially centered in which a band edge segments central opposing the opposite band edges are arranged substantially parallel to opposite side edges and mediated to said opposite side edges. Willing in the proximity of each of the corners of the handle panel is a folding reinforcement that extends from a first point of end near an associated corner of the corners up to a second end point close to the centrally arranged area of the band element so that when a force is exerted that is substantially normal to a plane where the handle panels on the centrally arranged area, the element of band bends substantially out of the plane from a skewed position close to the plane.

Other advantages and objectives of this invention will become apparent from the following description, attached drawings and claims attached.

Detailed description of the embodiments preferred

In all drawings, the same are used reference numbers to indicate equivalent characteristics or the like of the invention.

For the sake of a better understanding, it is done reference to figures 1, 2 and 3 simultaneously. The figures 1 and 2 illustrate a box 10 having a handle structure according to a preferred embodiment of the invention. Figure 3 illustrates the semi-finished 12 from which the box is formed Figures 1 and 2.

Figure 2 illustrates the transverse alignment of cans C with respect to the handle structure 10 of the box according to a preferred embodiment of the invention. Figure 2 also represents the way in which the top wall of the box 10 that comprises its handle structure curves up when it apply a force F to lift the band element 14.

The environment of the handle structure of the invention is a box 10 that forms a package from a series of panels joined together. In figure 3, they can be seen with greater clarity the main joining panels 20, 22, 24, 26 and 28 that they form a tubular structure when the panels are joined more ends 20, 28.

The most extreme panels 20, 28 of the semi-finished 12 form the wall or top panel of the box 12 containing the handle structure For the sake of a better explanation, each part of the upper panel 20, 28 is further described in segments. Every half panel features a band element 46, 44 with a side area inclined 30, 38 mediates the end areas. The remaining part 40, 42 of the upper panel is arranged along an edge upper panel side. The fins 80 join the end edges of the top panel. Each fin forms at least a part of a end wall in the raised box.

In the raised box 10, the band elements 46, 44 overlap, to a certain extent, and the side areas inclined 30, 38 completely overlap to produce a handle substantially reinforced. In the end areas of the elements a band-shaped handle 46, 44 extends diagonally one sheet from the apex of a side edge and an end edge of the panel.

Elongated sheets 54 are determined by a pair of separate lines formed by a perforated line 57 that is extend diagonally from the vertex mentioned above and a marked line 56 that is disposed between the perforated line and the end edge of panel 20, 28. The intersection of the line marked 56 and perforated line 57 improves the effectiveness of the invention.

A connecting element 70 joins the band element 46, 44 and a portion of zone 42, 40 of the upper panel adjacent to the band element 46, 44. The tension on the end zone of the handle structure is directed more evenly towards ends of the handle structure and the box through the coincidence of an edge 72 (shown as a cut line in semi-finished 12) of the band element 46, 44 with the line marked 56 of the elongated sheet. An additional improvement is obtained of the operation of the handle structure by termination of the edge 72 in the connecting lug 70.

Optionally, the end areas of the panel upper, which coincide with the end areas of the structure of handle, can have a panel of intermediate sheet 50 determined by a marked curved line, or arched, 58, which in the semi-finished 12, coincides with perforated lines 57 of the elongated sheets of the handle structure. They can form another pair of intermediate sheet panels 60 on the opposite side of the box.

Band element 44, 46 provides a handle which directs the tension towards the ends of the box. The characteristics of the handle structure described in then make the band element 30, 38 and other elements on the upper panel flex, or curl, in a way default outstanding out predetermined when lift the box 10 when exerting a force F. The structure of the elongated sheets 54 causes the upper panel 20, 28 to curve from concave way in a graduated configuration, ascending towards above, when the box is lifted by force, as illustrated in figure 2. The inclined side band element 30, 38 provides a convenient, secure handle. The lugs 70 mutually join the band element 46, 44 and the panel areas adjacent upper 42, 40. This mutual union makes the panel upper 20, 28 maintain a more contiguous configuration when Pick up the box. The lateral areas 42, 40 of the upper panel they have a tendency to bend away from the element of band. The binding lugs inhibit such displacement and promote a more attractive appearance and greater panel integrity top of the box.

Intermediate sheet panels 50, 60 allow that the corners of the box 10 are arranged tighter when transversely line C cans or similar items in the box with respect to the longitudinal dimension of the box and the panel top, as shown in figure 2.

The structure of the invention provides a handle that is reinforced and that directs the tension out of it towards the ends of the box while collaborating with the box to maintain an aesthetically pleasing appearance and greater integrity when he gets up

Referring below so simultaneous to figure 4 and figure 5, they are shown a box presenting an alternative preferred embodiment of the handle structure according to the invention. In figures 4 and 5, the characteristics that correspond to equal characteristics of the preferred embodiment of the invention discussed above and illustrated in figures 1 to 3 have been indicated by them reference numbers but of a series "100". For example, him panel 24 of the first embodiment is indicated as 124 in the alternative preferred embodiment.

In the alternative embodiment of the Figures 4 and 5, a first corner sheet 200 is formed in each corner of the upper wall in which the structure is formed of handle by means of a perforated line 191 ("perforated" due to which consists of cutting segments and marked segments alternates) and a first marked corner line 191 that extends convergently from the corner of the wall or panel upper towards the end edge of the band element 144. The various "sheets" of this embodiment are also sometimes mentioned here, for the sake of better explanation, such as "reinforcements" and "folds". The line perforated 190 intersects the nearest vertex of the upper wall in which a side edge and an end edge of intersect the upper wall The first line marked corner 191 is arranged intermediate between perforated line 190 and the side edge from the upper wall. A second line marked corner 192 is arranged adjacent to the first marked corner line forming other sheet or reinforcement. At each corner of the side wall 122, 126 a diagonal cutting line 193 adjacent to the wall is arranged superior in alignment coinciding with the first marked line of corner 191.

The cut line 172 that determines each edge of the ends of the band element can present many orientations but in the preferred alternative embodiment illustrated is optimally arranged in longitudinal alignment substantially parallel with the band element and the edges upper wall sides.

The lugs 170 that serve as handle reinforcements (sheets / folds) are formed by lasa marked lines of lug 194, 195. Although marked lug lines may present many different alignments with respect to each other, in the preferred alternative embodiment illustrated they are not parallel. One of the marked lines of lug 195 is directed towards the hand opening. Each lug 170 is determined also by the lines of cut 172 and 196 that determine the edges of the band element.

Referring below particularly to figure 5, the particular arrangement of the elements of the handle structure of the embodiment alternative preferred described above and illustrated in the Figure 5 causes the upper wall of the box to deform so controlled and direct voltages by default. Doing particular reference to figure 4, each cut line 172, 196 that separates the structure of the band element from the rest of the upper wall and lugs 170, respectively, is interrupted by a notch element that provides the joint between these elements. When the band element is lifted to exert a force F, notch elements make the element of band 144 and lugs 170 separate from each other and from the wall top by default so that the band element curves outward and reinforcements 200, 202 and 204 move angularly with respect to each other. Optimally, the first reinforcement 200 moves to an arrangement within the element of curved band out. The lifting force exerted on the box causes the deformation to produce the union between the diagonal cut lines and the first lines marked. This deformation in turn causes the first reinforcement 200 to extend on the edge of the side wall of the box. The disposition of elements described directs the tension towards the corners of the box. Also, when items such as C cans are lined up in the box, the cans enclosed in the corners of the box, adjacent to the first reinforcements, act as a "beam" or an element of reinforcement.

Optimally, when the item is lifted band, the set of notches that joins the band element 144 and the lugs 170 is in front of the set of notches that joins the band element in the vicinity of the lugs 170 and the rest of the upper wall

The primary elements of the handle structure of the invention set forth are the band element 30/38 and 130/138, separated from the handle panel 44/46 and 144/146, and those that are mentioned in this part of the description as line segments of separation 72 and 172. Each separation line segment is extends between a point that is in the vicinity of a corner of the handle panel and a second point that is in the vicinity of the area centered arrangement of the band element. This arrangement produces a spring-shaped relationship between the band element and the handle panel so that when a force F is exerted on a centrally arranged area of the band-shaped handle in one direction substantially perpendicular to a plane (or theoretical plane) in which the handle panel is arranged, the band element bends towards outside with respect to the plane from a skewed position in the proximity of the plane, as illustrated in Figures 2 and 5. The arrangement of elements just described create essentially a sheet comprising the fold 70 and 170 that joins the end areas of the band element with the rest of the panel handle. The tension due to the weight of the box (and the force of F offset used to lift and hold the box) concentrated from the ends of the band element towards the corners and end walls and side wall areas adjacent to the box instead of in non-convenient areas of the panel of handle and of the centrally arranged area of the band element that They would probably tear and break. The substantial separation of the centrally arranged area of the band element of the panel plane handle helps facilitate tension dissipation the way which has been described above.

Segment line segments can be arranged in several optimal arrangements such as parallel to the side edges of the handle panel and away from the panels laterals as the separation line extends to the end edges of the handle panel. In a box in which they are packed cylindrical items such as cans C, the end point of the line segment that is closest to the corner optimally terminates on the tangent line T or in the vicinity of the same in which the end can of the can arrangement packed is arranged tangent to the handle panel.

Frangible elements, or notch elements 74, 76 and 174, 176 are optimally arranged by bridging in the sheet comprising the folds 70 and 170 and the element of band and bridging in the separation line segments 72 and 172, respectively, so that when a force is exerted that it is substantially perpendicular to a theoretical plane of the handle panel over the centrally arranged area of the band element, said band element bends out of the handle panel in a coordinated sequence that starts in the maximum proximity of the area arranged centered and progressing to the respective edges opposites

The reinforcements 54 and 200 that have been described previously they have the same function as those described previously. These reinforcements extend between the endpoint Closer and the corner itself. Reinforcements can be formed to from a pair of marked lines, a pair of perforated lines or a combination of a pair of mismatched lines of a line marked and a perforated line. Modifications can be made on the above, without departing from the scope and of the spirit of the invention that is claimed.
