Description

The present invention relates to a packaging for devices, in particular for electrical installation switching devices having an interior, which is bounded by a bottom wall, a front wall, a rear wall, a cover, a first and a second side wall, wherein the first and the second side wall each having a first , second, third sidewall portion and a sidewall portion, the first sidewall portion on the rear wall, the second sidewall portion on the bottom wall, the third sidewall portion on the front wall, and the sidewall portion on the lid are integrally formed, the surfaces of the sidewall portions add together at most to the surface of the sidewall portion in that the side wall sections cover the side wall sections, the cover has, on the side facing away from the back wall, a tab which, in the packaging state, is detachably connected to the inner surface of the front wall and the side wall sections each perforation are connected to the lid such that the lid is separable from the side wall portions.

Such packages are used to hold devices to be transported, wherein in such a package, one or more such devices may be used. In the EP 1 591 366 A2 discloses a package having the features of the type mentioned. In the known type of packaging, however, problems may occur if the package is exposed to it's devices strong vibrations, especially during transport. Any shock pulses that occur can be transferred from the packaging to the device located therein be, which disadvantageously at certain points, the device can be damaged.

The invention has for its object to provide a package of the aforementioned type, in which the disadvantages mentioned are avoided, in particular a packaging is created in which the devices arranged within the package remain intact, even if strong pulses from the outside act on the packaging , At the same time the packaging cost should be kept as low as possible.

To solve this problem, a packaging for devices with the features of claim 1 is proposed. In the dependent claims preferred developments are carried out.

For this purpose, the invention provides that the first and the second side wall each have at least one first damping tab, which is arranged on one of the side wall sections, wherein the first damping tab is provided on the side facing away from the wall of the side wall portion and foldable over a fold line on the respective side wall portion is.

The basic idea of the present invention is to form the packaging with a first damping flap on each side wall, which is applied to at least one side wall section when the package is folded, thereby increasing the wall thickness of the package and forming a kind of crumple zone inside the packaging, protects equipment from external impact. The first damper tab is preferably provided on the first and second sidewalls. In addition, all three side wall sections can have a first damping flap. In this possible embodiment, each side wall is additionally reinforced by three damping lugs in their wall thickness. However, it has been found for some applications that only one arrangement of a first damper tab on one of the sidewall sections per sidewall may be sufficient to reliably protect the devices disposed within the package by the shocks applied to the package. In a preferred embodiment of the invention, the second sidewall portion, which is disposed between the first and third sidewall portion immediately adjacent to the bottom wall, is configured with the first damper tab. When assembling the package is suitably kinked about the fold line about the fold line which is disposed adjacent to the adjacent sidewall portion, and directly abuts on the inner surface of the sidewall portion. One of the essential advantages of the present invention is that for shock absorption no additional parts have to be fed into the packaging, such as corrugated board or polystyrene elements, which are known to be inserted into the interior. According to the invention, the packaging cost is thus significantly reduced, at the same time good damping properties are achieved by the packaging. During the assembly of the packaging, a shock absorber system, which is characterized by the damping flap, is thus generated in the interior of the packaging, virtually in an integrated manner.

In a preferred embodiment of the package, the tab on the side facing away from the lid on a second damping tab, wherein the tab and the second damping tabs are separated by a fold line. This second damping flap represented a kind of extension of the tab, wherein in the packaging state, the second damping tab rests against the inside of the front wall and thus additionally reinforced in the wall thickness. In one possible design alternative, the packaging may be reinforced on both side walls and at the same time on the front wall by the first and the second damping tabs. The first and the second damping tabs are advantageously punched out of a basic cut of a cardboard material. The fold line separating the first and second damper tabs from the adjacent wall portion (tab, sidewall portion) may be formed as a fold line. Further, the fold line may be formed with a perforation and / or with punch-throughs. As a result, a kind of weakening along the fold line is formed, so that the Umbiegevorgang the damping lugs along the associated fold line simplifies and a machine bending is predetermined at these locations. By an additional use of punching along the fold line, a further improvement of the bending or the folding of the damping flap can be achieved. Advantageously, the punch-throughs are slit-shaped, these extending along the fold line. Conveniently, a plurality of punctures are arranged at a distance from each other along the folding line.

It is particularly advantageous that the first damping flap in the packaging state is adhesively bonded to the inner surface of the respective side wall portion, in particular via an adhesive. Furthermore, it is advantageous to also adhesively connect the second damping flap to the front wall. Of course, other positive and / or positive and / or cohesive connections between the first damping flap and the associated side wall portion and the second damping flap and the front wall may be provided.

A measure improving the invention provides that the second damping flap is glued to the inner surface of the front wall, wherein the second damping flap is attached with an adhesive force to the front wall, which is less than the adhesive force acting between the tab and the front wall. In the unopened state of the package, the tab and the second damper flap is a kind of tamper-evident closure. When the package is opened for the first time, the tab is advantageously pressed into the interior of the package, thereby releasing the adhesive bond of the tab on the inside of the front wall. Further, the fold line which separates the tab from the second damper tab is designed with a perforation such that when the tab for the opening operation is pressed in, the said perforation is simultaneously torn open. Since the second damper tab is attached to the front panel with a significantly higher adhesive force, the second damper tab remains internal to the front panel. The tab is now separated from the second damper tab and the front wall and can be swung out with the lid from the packaging for the opening process. Advantageously, the lid on both sides of two side wall portions, which are separated by a fold line to the lid. In this case, this fold line is provided with a corresponding perforation, so that in the above-mentioned first opening operation, the lid can be swung out of the packaging during lifting, at the same time the perforation along the fold line between the side wall portion and the lid is torn open. After the lid is lifted with the tab, one or more devices can be removed from the package. The lid can then be closed again by folding the lid down and inserting the tab on the inside of the top edge of the front panel.

In order to ensure a satisfactory first opening operation, the front wall has a free edge, which is formed with a recess. Advantageously, the recess forms an opening to the interior, which is completely closed by the flap on the inside of the front wall. The tab, including the second damper tab, is located behind the front panel, with a small portion of the tab visible through the recess on the front panel. This visible portion represents the operating area for the opening process. Preferably, the user presses with his thumb through the recess on the attached behind the front wall tab, which dissolves according to the pressing force of the front wall. As the tab is pressed into the interior of the package, it pivots along the fold line separating the tab from the lid. So that when the first opening operation, only the tab separates from the front wall, the tab has a height which is greater than the height of the recess. This means that the tab protrudes deeper in the direction of the bottom wall along the front wall than the opening of the recess. Here, the fold line, which lies between the second damper tab and the tab, below the recess, not visible on the inside of the front wall.

Figure 1 and Figure 2 show a possible embodiment of the package 1 according to the invention, in which a base cut 10 is punched out of a cardboard material having a bottom wall 11, a front wall 12, a rear wall 14 and a lid 15. The lid 15 is separated from the rear wall 14 by a fold line 29. The rear wall 14 in turn is separated by the fold line 30 from the bottom wall 11, which in turn is separated by a fold line 31 of the front wall 12. In the present embodiment, the lid 15, the rear wall 14, the bottom wall 11 and the front wall 12 are formed rectangular. In a further, not shown embodiment, said walls 11,12,14,15 may of course be square. According to the illustrated embodiment, the front wall 12 and the rear wall 14 along the fold lines 30,31 are folded up perpendicular to the bottom wall 11. The fold lines 28,29,30,31 facilitate the buckling of the respective packaging wall. In the packaging state, the lid 15 is substantially parallel to the bottom wall eleventh

At the perpendicular to the fold lines 29,30,31 extending narrow side edges of the front wall 12, the bottom wall 11 and the rear wall 14 are on both sides first 16a, 16b, second 17a, 17b and third side wall portions 18a, 18b integrally formed. The first side wall portion 16a, 16b is connected via a fold line 32 with the rear wall 14. The second side wall portion 17a, 17b is separated by a fold line 33 to the bottom wall 11. The third side wall portion 18a, 18b is also connected via a fold line 34 with the front wall 12. The first 16 a, 16 b and the third side wall portion 18 a, 18 b have an approximately rectangular, triangular-shaped peripheral contour, which are arranged mirror-symmetrically to the bottom wall 11. The second side wall portion 17 a, 17 b is formed substantially with a trapezoidal peripheral contour, the base of which is formed by the narrow side of the bottom wall 11. The peripheral contour of the second side wall portion 17a, 17b is selected so that in the folded state, ie when the front wall 12 and the rear wall 14 perpendicular to the bottom wall 11 and the side wall portions 16a, 16b, 17a, 17b, 18a, 18b also perpendicular to the rear wall 14th and the front wall 12 are folded, the three side wall portions 16a, 16b, 17a, 17b, 18a, 18b covering an area substantially corresponding to the side walls. This cover the Side wall sections 16a, 16b, 17a, 17b, 18a, 18b in the mounted state not, which is particularly illustrated in Figure 3.

The second side wall part section 17a, 17b respectively has a first damping tab 22a, 22b, the damping tab 22a, 22b being provided on the side of the second side wall section 17a, 17b facing away from the bottom wall 11. Between the first damping tabs 22a, 22b and the second side wall section 17a, 17b, a fold line 23a, 23b is arranged, which runs parallel to the fold line 33. The first damping flap 22a, 22b is also substantially trapezoidal. At the fold line 23a, 23b punching not shown are provided to facilitate the buckling of the first damping flap 22a, 22b, which is shown in Figure 2. The peripheral contour of the first damper tab 22a, 22b is shaped to at least partially coincide with the peripheral contour of the second sidewall portion 17a, 17b as the first damper tabs 22a, 22b fold along the fold line 23a, 23b onto the second sidewall portion 17a, 17b becomes.

At the free longitudinal edge of the lid 15 is a tab 20, the narrow side edges of the longitudinal edge tapering towards each other, so that the tab 20 can be brought into contact with the inner surface of the front wall 12.

At the free longitudinal edge of the tab 20, a rectangular, second damping flap 24 is formed over a fold line 13. This fold line 13 has a perforation with punch-throughs 25. The second dampening tab 24 is intended to be glued to the inside of the front wall 12 during assembly of the package 1. In this way, the second damper tab 24 is a partial thickening of the front wall 12. This thickening by the second damper tab 24 acts as well as the thickening by the first damping tabs 22a, 22b as a buffer for the present in the package 1 devices. The fold line 13 is designed so that in the bonded state, the tab 20 can be pushed away with the fingers slightly inward towards the interior of the package 1, without the second damping tabs 24 is detached from the inside of the front wall 12. At the free edge of the front wall 12, a U-shaped recess 26 is executed.

At the narrow side edges of the lid 15, a side wall portion 19 a, 19 b are arranged on each side. Here, the side wall portions 19a, 19b are dimensioned so that they can be folded down in the direction of the bottom wall 11 along the folding line 21 during assembly of the package 1 and the folded side wall sections 16a, 16b, 17a, 17b, 18a, 18b including the first Cover damping flaps 22a, 22b completely.

If the wound packaging 1 according to FIG. 1 is to be equipped, first the two first damping flaps 22a, 22b are folded along the fold line 23a, 23b onto the second side wall section 17a, 17b and glued together with corresponding adhesive dots. The result is a partially doubling of the wall thickness of the second side wall portion 17a, 17b, which is shown explicitly in Figure 2 and Figure 3. At these locations, the side panel sections 17a, 17b reinforced in this manner act as a type of cushioning buffer after assembly of the package.

Subsequently, the front wall 12 and the rear wall 14 are folded up along the fold line 30,31, wherein the lid 15 is folded around the fold line 29 forward toward the front wall 12. Now, the tab 20 is folded with the attached second damping flap 24 down. The unit of tab 20 and the second damping tab 24 can now be applied to the same parallel to the inner surface of the front wall 12, wherein the second damping tab 24 is glued by means of prepared adhesive dots on the inside of the front wall 12. Also, the tab 20 is glued by means of adhesive dots on the upper edge of the inner side of the front wall 12. The adhesive points for the tab 20 are in this case of weaker adhesive force than the adhesive points for the second damping lobe 24th

In this way, a tube with a rectangular cross section has now been created. Figure 3 shows a view into the so-called, resulting tube in the direction of the arrow of Figure 2, wherein the one side wall consisting of the side wall portions 16b, 17b, 18b and from the side wall portion 19b is fully opened.

From Figure 3, a rectangular outer contour of the package 1 is visible, which is formed from the front wall 12, the bottom wall 11, the rear wall 14 and the lid 15. The still unfolded side wall portions 19a, 19b are not visible here, because they coincide in the narrow side view of the lid 15. Subsequently, first, a side wall is formed, which is composed of the first 16a, second 17a (including the first damping tab 22a) and the third side wall portion 18a. Here, the first 16a, and the third side wall portion 18a is folded inwards and the second side wall portion 17a with the first damping flap 22a resting thereon. In the following step, the side wall portion 19a is folded down around the fold line 21 in the direction of the bottom wall 11 and glued by means of prepared adhesive dots with the side wall portion portion 16a, 17a, 18a, so that there is an overall closed side wall. Figure 3 shows this insight into the only one-sided closed tube. Also visible in this view is the first damper tab 22a, which protrudes on the sidewall and is attached directly to the second sidewall portion 17a via an adhesive bond.

The, side wall portions 16b, 17b, 18b and the side wall portion 19b are not yet folded, so that the overall result is a unilaterally open packaging tube. On the side wall 16a, 17a, 18a, 19a opposite, open side wall thus forms a filling opening through which the devices can be inserted into the interior 27 of the package 1. This filling can be carried out very easily on an automatic packaging and filling machine.

After filling, the side wall portions 16b, 17b, 18b and the side wall portion 19b are folded accordingly, wherein the side wall portion 19b is bonded to the side wall portions 16b, 17b, 18b. Thus, the devices are incorporated in the finished package 1, wherein the package 1 is closed and the devices are shock-protected by the damping tabs 23a, 23b, 24.

To open the package 1, the tab 20 is pressed against the U-shaped recess 26 with a finger, preferably with the thumb. Firstly, the adhesive points of the tab 20 on the inside of the front wall 12 to solve, and second, the perforation of the fold line 13, which connects the tab 20 with the second damping tab 24, torn open. As can be seen in FIG. 1 and FIG. 2, the fold line 13 has punch-throughs 25 which are arranged at a distance from one another along the fold line 13 are. The lid 15 can then be lifted upwards, wherein the fold line 21, which are also carried out with a corresponding perforation, are torn open. Subsequently, the lid 15 can be lifted upwards and a device removed. In the next step, the lid 15 can be closed again, in which it is folded down and the tab 20 is inserted on the inside of the upper edge of the front wall 12.

According to FIG. 4, a further view of the packaging 1 according to the invention is shown. In this view it is clear that the side walls are reinforced by the outer side wall portion 19a, 19b and by the inner first damping tabs 22a, 22b. The second damping flap 24 is applied over a large area to the inside of the front wall 12, which also a wall thickness gain of the package 1 is achieved.

Furthermore, it is illustrated according to FIG. 3 that the cover 15 and the tab 20 are separated by the fold line 28, which is aligned with the free edge of the front wall 12, whereby, according to FIG. 4, the fold line 13 which separates the tab 20 from the second dampening tab 24, is arranged below the recess 26 on the inside of the front wall 12.

In a further, not shown embodiment of the packaging 1 according to the invention, the first 16a, 16b, and / or the third side wall portion 18a, 18b may also be designed with a damping flap which on the free side of said first 16a, 16b and / or the third Side wall portion portion 18a, 18b is formed. In this embodiment, not only the portion of the second side wall portion 17a, 17b is reinforced by the first damper tab 22a but also the first 16a, 16b and the third side wall portion 18a, 18b.

In order to make the contents of the package 1 visible to the user from the outside, the lid 15 and / or the bottom wall 11 can be designed with a transparent viewing window, for example. The transparent material may be made of plastic, which is positively and / or non-positively and / or materially connected to the packaging 1. In a conceivable embodiment of the invention, the transparent material may be fixed by laser welding to the interior 27 facing side of the respective wall. For example, the transparent material is as executed thin film, which may be designed as laser-transparent, wherein the surface of the lid 15 or the front wall 12 is laser absorbing. In this case, the said surface may be coated with a specific material so that the lid 15 or the front wall 12 becomes the absorbing medium. The laser welding can be done in a possible embodiment under a protective gas atmosphere. Other connection alternatives are also conceivable, for example by gluing the film to the lid 15 or to the front wall 12. Advantageously, the packaging 1 is made of cardboard or a recycled material. Furthermore, the packaging 1 may have on its visible outer surfaces imprints that signal, for example, instructions for the user to open the package 1 or the contents of the package 1. The fold lines 13, 21, 23a, 23b, 28, 29, 30, 31 are preferably designed as fold lines in order to allow easier bending of the respective adjoining walls.
