Abstract

The package has a body part (12), and side parts fastened at the body part. The body part is manufactured from a plane, rectangular or quadratic plate part, and folding lines of the side parts limits three sections. The lines are directed from each outer section side to a longitudinal wall. An adjacent section at the wall form a base part. Each side part has a side wall, base plate fixed at the base part and side plates. An independent claim is also included for a method for manufacturing the package.

Description

and its execution process " The invention in question relates to a package according to the generic description of claim 1 of the patent, as well as to the method of implementing a package according to claim 11 of the patent.

These are packagings, intended for example for horticultural products, assembled from a single sheet, for example corrugated board having two or more layers. These packages have a base, along which fold lines are attached the longitudinal walls. In continuation of the fold lines, the side walls are also attached to the base. The longitudinal walls and side walls are secured to each other by means of jaws.

In order to obtain this type of packaging, of different lengths, it is necessary to have pieces (sheets) dimensioned accordingly, which gives rise to a considerable expenditure in terms of machines and tools.

A determinate package for its category is disclosed in DE 196 02 688 A1. It has two side members, each with a side wall, a base jaws, two side jaw collars and a cover-like collar operating cover. The side members are disposed at a certain reciprocal distance or directly connected to each other through their joint members at the base, thereby forming a double box. On the side members and flat bottom pouch, positioned thereon, a locking cap is placed in an inverted position.

From this perspective, the present invention aims to create a package which can be obtained in different lengths and with lower expenditure.

This object is achieved by the presentation of a package according to claim 1 of the patent and the method of execution according to claim 11 of the patent. The package according to the present invention is constituted by a body forming a base and longitudinal walls, as well as two side members of identical configuration and which are attached and fixed to the body. This enables simple packages of different lengths to be obtained in that the only factor that changes is the length of the body, since the side members can remain unchanged. It is obvious that obtaining the package according to the invention presupposes a substantial saving in terms of logistics and handling as well as all the costs inherent to the tools required. In addition there is an increase in productivity and in particular flexibility in the development and production phase. There is still a possibility that in the package according to the invention a material for the body member and another material may be used for the lateral elements. In this perspective, depending on the objectives to be attained, the most suitable materials may be used, for example corrugated cardboard with one or more layers, plastic or the like.

In the case of packages according to claims 2 and 3 of the patent, body segments have been assembled to form partition walls. These partition walls give great stability to the body and in particular to its base elements. Thus, in comparison with conventional packages sized for the same fillers, thinner materials can be used to obtain the package body. Thus, if corrugated cardboard is used, it is possible to use only one-layered carton, whereas other previously known packages required the use of double-layer corrugated board. Accordingly, the package according to the invention, and in accordance with this embodiment, allows a considerable saving of material. The packaging process according to claim 11 of the patent is extremely simple. The option for this form of packaging execution and by this method is indicated in the subsequent patent claims subordinate to it. The present invention is demonstrated and explained in more detail by means of an exemplary embodiment shown in the drawing.

Figures 1-4 show a plate 10 in four different stages of forming a body 12 from the plate 10 shown in Figure 4. Figures 5 and 6 show the execution of a side member 14) from a custom cut sheet (16). A carton 18, as shown in Figures 7 and 8, is obtained from a body 12 and two side members 14. The plate 10 of Figure 1 is formed of a thin rectangular cut sheet which material is, in this case, simple corrugated board. The longitudinal direction of the plate (10) is indicated by a double arrow L.

On the plate 10 are eight fold lines 20 parallel to the longitudinal direction L extending along the entire length of the plate 10. These lines may be obtained, for example, by grinding, milling, punching, etching, tracing, stripe marking or the like. Its graphic representation is the dotted. These fold lines (20) delimit nine segments, which are located at each end designated as segments (22). The ones that follow, as well as the one situated in the center are designated 24, each set of two, located between the segments 24, the designation 26. The width of the end segments 22 is designated Bl. These segments 22 will subsequently form the longitudinal walls 28 of the body 12. The width of the segments (24) is designated B2. These segments (24) will subsequently form the base members (30) of the body (12). The sum of the widths B2 results in the overall width of the body (12). The width B3 of the segments 26 is higher than the width Bl. The contiguous segments 26 each later form a partition wall 32 of the body 12. When, as in the present case, the width B3 is intended to be higher than the width Bl, the partition walls (32) have a height higher than the longitudinal walls (28). In this context, however, any height can be chosen by simply having a corresponding Width plate (10) and marking the fold lines (20) at the different desired locations.

In the embodiment of the body 12 shown in Fig. 4, from the plate 10, the end segments 22 are assembled so as to form a right angle with the base elements 30 arranged at a certain level . As is particularly shown in Fig. 3, the contiguous segments 26 are armed and, simultaneously, the base members 30 move towards each other until the segments 26, which form a partition wall (32) are fully abutted, as shown in Fig. 4. The assembled partition walls (32) form an adjacent 90 ° angle with the contiguous base members (24). The segments 26, which form a partition wall 32, are mutually fixed, preferably by gluing, to the face. This connection of contiguous segments 26 may, however, also be effected by other common processes such as joining, interlocking or the like.

The partition walls 32 and the longitudinal walls 28 impart enormous stability to the body so that their base members can withstand a considerable load without suffering disproportionate deformation.

In Fig. 5, the cut sheet sized for side member 16 has a substantially straight cylindrical segment, intended to form a side wall 34. The upper part of Fig. 5 shows how the side wall 34 is, on the one hand, delimited by the collar 36 of the custom cut sheet for side member 16 and on the other hand delimited by a fold line of the base (38) with parallel. The lateral boundary is indicated by two side fold lines (40) perpendicular to the fold line of the base (38). The distance between the two side fold lines 40 corresponds to the width B of the body 12, shown in Fig. 4. The distance from the fold line of the base 38 to the collar 36 corresponds to the width B3 2 and therefore to the height of the partition walls 32.

Along the side fold lines (40), the side jaws (42) join the segment forming the side wall (34). Its shape is essentially an L being divided by a base / lateral folding line 44. The base / side fold line 44 has a straight line progression in the extension of the fold line of the base 38. Along the fold line of the base (38), the copper joints of the base (48) join the side wall (34). Its width, measured at the perpendicular of the folding line of the base (38), corresponds to the width of the lateral / base part (46). The base jaws (48) and the side / base jaws (46) are separated from each other by a segment in the form of an isosceles right triangle, this triangle being symmetrical to the imaginary extension of the lateral wall line (40). In the imaginary intersection zone of the side fold lines 40 with the fold line of the base 38 and the base fold / side lines 44, the custom cut sheet for the side element 16 has a essentially rectangular aperture (50). The latter is symmetrically disposed relative to the Side Folding Line 40 and extends from the fold line of the base 38 in a smaller portion to the corresponding side / base part seal 46 and covers the (48) and, in a larger portion, the side wall (34) and the corresponding side jaws (42). The portion with which aperture 50 extends to the base-copper cover 48 and to the side-base cover copper 46 is slightly greater than the thickness of the custom cut sheet for side member 16, .

In addition, the custom cut sheet for side member 16 has at the upper end of each side fold line 40 a stabilizer tab 52 whose configuration is diametrically opposed to that of the aperture 50.

To assemble a side member 14 from a custom cut sheet to side member 16, the side jaws 42 are positioned along the side fold lines 40 until each one forms a right angle with the side wall (34) lying in the opposite direction. Likewise, as shown in Fig. 6, the

The side / base jaws (46) are placed in the opposite direction to the inner part next to the fold line of the base (38) and / or to the lines of the base (48). folding base / side portion (44), are positioned horizontally of the plane. In this way, the apertures (50) are located in the lower corners of the side member (14). The same is true of the stabilizing lugs 52 in the upper corners of the side member 14. The package 18, as shown in Figures 7 and 8, is obtained by the following procedure: in the body 12 a side element 14 is positioned at the diametrically opposite ends in the longitudinal direction L. Accordingly, the base elements (30) of the body (12) come into contact with the copper-joints of the base (48), both the outer elements of the base (30) also come into contact with the side / base jaws (46) and the longitudinal walls (28) come into contact with the inner part of the side members (14) next to the side jaws (42). The base jaws (48) and side / base jaws (46) are secured to the base members (30) of the body (12), preferably by sticking to the face. Also in this case the fixation can be processed by other methods of general knowledge.

As exemplified in Fig. 8, the " arms " which extend in the perpendicular of the lateral folding lines 40 of the L-shaped side collars 42, have a height (measured from the base fold line / side portion (44) to its upper edge) essentially correspondingly at the height of the longitudinal walls (28).

The partition walls 32, as shown in Fig. 8, may show protruding lugs 54. For this purpose, in the plate 10 - Fig. 2 - in the fold lines 20, close to the segments 26, C-shaped notches will be effected with penetration in the plate 10.

As can be seen from Figures 5, 6 and 7, the copper-joints of the base (48) may also have a Latch (56) capable of being assembled.

Figures 9 and 10 show in perspective or side perspective two overlapping packages 18, analogously to that described above in the context of Figures 1-8. Here, the stabilizing tabs 52 of the carton 18 in the lower position engage the apertures 50 of the carton 18 located in the upper position, which results in a stacking situation of enormous stability. The side members 14 of the uppermost carton 18 rest along the collar 36 of the side wall 344 in the side members 14 of the carton in the lower position. If the partition walls 32 are the same height as the side walls 34, the overlying packaging bases 30 will also be supported by the partition walls 32 of the package 18 below. Of course, the option of a length L of the plate (10) allows the execution of packages (18) of different lengths. In this way, the plate 10 can also have a square shape. In the case where the width of the packages remains unchanged, lateral elements (14) of identical construction may be used irrespective of the length L.

Of course, it is also possible to carry a package (18) without partition walls (32). In this case, only two fold lines 20, which delimit two segments 22 and a segment 24, between them, should be provided on the plate 10. The segment at the end of each side is assembled as if it were a longitudinal wall 28, next to which the segment 24 forms the base 30.

There is also the possibility of providing a single partition wall (32). In this case, five folding lines 20 on the plate 10 are to be provided, which separate from each other six segments, namely two segments 22 located at the end, plus one on each side of the segment 24 and two between the segments (26). In arming the carton, these segments 26 then form a partition wall 32, the segments 24 form two base members 30 and the segments 22 form the longitudinal walls 28.

Of course, it is also possible for a method of construction to provide more than two partition walls (32). It is also possible, when cutting to the extent of the sheet for side element 16, to dispense with side jaws / base 46. In this case, the side jaws (42) must, however, be attached to the longitudinal walls (28). Of course, also in the case of side jambs 46, the side jambs 42 may be attached to the longitudinal walls 28.

It is also possible to divide the jaws of the base 48. In the case where the copper joint of the base 48 is sectioned or at least not close to the lateral fold lines 40, it should be noted that each base member 30 must be connected, at least in the sectoral manner , to a junction of the base (48) or to a part thereof. The package 18 may be provided with a lid. The device shown in Fig. 11, intended to assemble and assemble packages (18) according to the method described above, has five modules. Viewed from the production direction P, there is a forming module 58 and a folding module 60 for executing the body 12. There follows, in sequential order, a first assembly module (62) and a second assembly module (64) for mounting a first and / or a second side member (14). The last module provided is the delivery module 66 which presents the package 18 ready, which is collected in a forklift or transport and handling device. The forming module (58) has adjustable side stops (68) in the width of the plate (10). These center the plate (10), fed to the module by means of a conveyor (70), for example a belt conveyor. If the transport of the plate 10 is effected by means of a vacuum conveyor, the plates 10 will be released at times in the region of the side stops 68 so as to be aligned.

The side stops 68 follow, in the production direction P, a forming unit 72. In the present case, it has a rotatable driven shaft 74 perpendicular to the production direction P, positioned at the points where the grooving, milling or drilling discs 76 are located to execute the fold lines 20. Along the conveyance of the plate 10 by the forming unit 72 the marking of the fold lines 20 takes place at the desired locations.

Subsequently, the subsequent transport of the plate (Sv6) into a single piece already provided with fold lines (20), the folding module (60) is introduced into the next module. This has alignment stabilizers (785, so that the segment 22 at the end of each side can have a 90 ° fold with respect to a longitudinal wall 28. As indicated by the arrows 80, the alignment stabilizers 78 are adjustable from each other, so as to be able to align the segments 26 with the partition walls 32. The folding module 60 also has glue applicator elements 82 which, in the desired zones, apply glue to the segments. The folding module 60 may also be provided with compressor elements which, on both sides and until the bonding is consolidated, compress the segments 26 forming a partition wall 32. The body (12) obtained in the folding module ( 60) is conveyed to the first mounting module (62). It has a device (84) for rotating the bodies (12) 90 ° about a vertical axis in the production direction P from the longitudinal direction L. Adjacent the rotating device (84) is a device for folding side members (86). A conveying device indicated by an arrow 88 in turn in turn guides the sheet cut to the side member 16, leading it to the glue applicator elements 82, which apply glue to the jaws of the base 48, and on the side / base side jaws (46).

A conveyor device indicated by an arrow 88 directs a folded sheet to the folding device 16 and is already provided with glue to a folding device 90. In this arrangement, the sheet 16 is folded by the usual methods along the folding side lines 40, at an angle of 90ø, the sheet 16 being shown in a way that the side wall 34 is lies in a vertical plane with a progression parallel to the production direction P. In the folding device (90) folds of the base (48) and the lateral part / base assemblies (46) already folded back . The sheet 16 is represented by dotted lines and the finished part 14 by means of solid lines.

As indicated by another arrow the side member 14 is moved towards the body 12 until the side wall 34 abuts the body 12.

Then the side member 14 is raised so that it covers it together with the base members 48 and the covers part side / base 46 already provided with glue to contact the base members 30 of the body ( 12). It will be advantageous to provide clamping members so as to allow the joint compression of the copper joints of the base 48 and of the copper parts side / base 46 as well as of the base elements 30 of the body 12, making compression until the gluing process is complete. The body (12) provided with side member (14) is then routed in the production direction P of the second assembly module (64). This shows a further side member folding device 86 'having a configuration symmetrical with respect to the side member folding device 86. Here, in exactly the same manner as described above, a second side member 4 is mounted, being positioned adjacent the body (12) and glued thereto. The finished package 18 then proceeds in the production direction P and is conveyed to the delivery module 66. It is feasible to provide a filling module between the first mounting module (62) and the second mounting module (64), so that the body (12) provided with a single side member (14) can be supplied with the material to pack

It is also possible for the two side member folding devices 86 and 86 'to be positioned symmetrically adjacent to the rotation device 84.

In this case, the two lateral elements (14) are simultaneously applied to a body (12).

There may also be provided only one side-folding device (86). Upon assembly of one of the side members 14, the body 12 is rotated 180Â ° by means of a rotation device 84, to enable the other side member 14 to be mounted by the element folding device (86).

If it is not necessary to affix elements, the apparatus does not need to have adhesive applicator elements 82 and 82 '. It shall then have in its modules, stapling, welding, ultrasonic equipment or any other known equipment capable of bonding materials. The package (18) according to the invention is executed simply and fully automatically. It should be noted that packages (18) of different lengths can be made in the same equipment, only being necessary to make adjustments according to the lengths.
