DESCRIPTION

Bumper packaging

The present invention relates to a bumper packaging made from a cut-out of cardboard or flexible corrugated board material, comprising a parallelepiped body or having a basic prism shape, having a body front wall panel, a rear body wall panel and a body bottom panel, as well as two side parts parallelepiped or having a basic prism or truncated pyramid shape, arranged on opposite sides of the body that respectively have a side part front wall panel , a side part rear wall panel and a side part bottom panel, the front body wall panel and the body bottom panel being articulated with each other, as well as the side part front wall panels and the panels side part background, preferably by means of longitudinally oriented front wall folding lines, the side part front wall panels forming with the body front wall panel and the side part rear wall panels respectively forming an obtuse angle with the panel rear wall of body. The invention further relates to a cutout for a bumper packaging made of cardboard or flexible corrugated cardboard material, the cutout having in a row at least three rectangular rear wall panels, which are hinged to each other in the cutout with fold lines. of rear wall panels oriented transversely, at least one rear wall panel being a body rear wall panel and at least two rear wall panels forming two side rear wall panels, which are hinged to the body rear wall panel by means of rear wall folding lines, background panels that are at least partially cut from each other, which are hinged in the rear wall panels with longitudinally oriented background folding lines in the cutout, as well as at least three wall panels front that are articulated in the bottom panels with front wall folding lines oriented longitudinally in the cutout, being at least two front wall panels and two side front wall panels, as well as a method for the mechanical manufacture of a pre-packaged bumper packaging.

Bumper packaging is generally known. The bumpers are essentially U-shaped with wide connecting legs in relation to the two side legs. Due to this shape and size they are bulky. As they are also quite delicate and unstable, it is important to protect them well during transport and storage. Therefore, the packaging of the bumpers is of great importance. On the other hand, taking into account the above, wrapping the bumpers is not trivial. One packaging option is described in DE 202 08 522 U1. The packaging described there consists of two support strips, which are connected to each other by means of a connecting rib, as well as at least one connecting tab. This packaging adapts very well to the shape of the bumper. However, it only guarantees partial coverage of the bumper, so it does not offer complete protection and is particularly unsuitable for bumpers that have already been varnished.

Additionally, the bumpers were packed in parallelepiped boxes. Packaging of this type is not adapted to the shape of the bumpers, which causes problems. In addition to the fact that the material requirements and in particular the volume of the packaging make transportation and storage more expensive, the large empty space that packaging of this type presents when full often leads to deformation and therefore damage to the packaging.

Therefore, packaging was developed that stably completely envelops the bumper and is adapted to the U-shape of the bumper. Bumper packaging of this type, as described in the preamble of claim 1, is known, for example, from JP 2007-050920 A, CN 202072154 U, DE 10 2014 100 779 A1 or EP 2 861 500 A 1. They are typically formed from a cutout of cardboard or corrugated board material that is unfolded and assembled to form the finished bumper packaging. The necessary joints of parts that are not already articulated with each other in the cutout are generally made using insertable tabs; It is also possible to glue them, although it is preferable to insert them. Depending on the type of packaging, it is also common to secure one or more of the insertable tab joints by using adhesive tape to prevent the tab from coming off.

However, the assembly of packaging of this type is quite difficult and expensive and requires, although in principle it is possible for one person to assemble it, preferably two people, since several pieces must be held and inserted at the same time. This causes high processing costs, which are added to the price of the packaged bumper and must therefore be borne by the customer.

Another aspect of packaging is the space it requires when delivered. Due to the size of the packaging, the cutouts are also of considerable size. The quality of the cutting does not allow, or only to a very limited extent, to reduce its surface area by folding for transport, making it difficult to handle the cuttings.

Therefore, the present invention was based on the objective of providing a bumper packaging that solves the problems described above and that can be assembled easily and in less time and preferably by a single person. Furthermore, in the supplied state, the packaging should be able to be folded to a smaller size, with a smaller surface area than conventional packaging and which simplifies handling.

This object is achieved according to the invention by a bumper packaging of the type mentioned at the beginning, in which each side front wall panel is firmly connected to the body front wall panel by means of a front wall adhesive tab and each side part bottom panel is firmly attached to the body bottom panel by a bottom panel adhesive tab.

"Fixedly attached by an adhesive tab" in the sense of the invention means in this regard that the adhesive tab overlaps the panel to which it is permanently attached and is permanently connected thereto, preferably by gluing. However, other permanent joints, such as stapling or riveting, are also possible.

When speaking of "gluing" within the scope of the present invention, all known adhesives can be used, such as in particular glue, two-component glue or hot glue, glue being particularly preferred. Different adhesives can also be used for different gluing, depending on the desired properties.

"From a cutout" in the sense of the present invention means that the cutout is preferably formed in one piece and the individual panels and tabs of the cutout are formed by fold lines by which the respective panels and tabs are also hinged. each other. However, the present invention also comprises cutouts formed from several parts, the parts being firmly joined together other than by folding lines, for example by means of an adhesive tab joint.

"Joined together" in the sense of the invention means that two pieces are connected to each other. This can be done by means of tabs, in particular by gluing and adhesive tabs. Particularly advantageously, the articulation is carried out by means of folding lines.

The object is further achieved by a cut-out for a bumper packaging of the type mentioned at the beginning, in which a bottom panel is a body bottom panel, which articulates two bottom adhesive tabs by respectively an adhesive tab folding line , which start from a near end of the bottom folding line that articulates the body bottom panel, running obliquely with respect to it, and two bottom panels being side part bottom panels, respectively adjacent to one of the bottom adhesive tabs, and a front wall panel being a body front wall panel, which articulates two front wall adhesive tabs by respectively a transversely oriented adhesive tab folding line.

Such a bumper packaging according to the invention or such a cutout according to the invention can be completed very easily and by a single person. The time required to erect the package is significantly reduced compared to the time required to erect a conventional bumper package to approximately 30 seconds for a bumper package according to the invention. This significantly reduces personnel costs for assembly, which also significantly reduces the total packaging price. In particular, by the fact that the side front wall panels and the body front wall panel, as well as the side part bottom panels and the body bottom panel are firmly connected to each other by adhesive tabs, The number of necessary insertion joints that have to be closed for the assembly of the packaging is reduced, which represents a notable saving in assembly time.

A cutout according to the invention has an inner side and an outer side. When the packaging is assembled, the inner side faces the interior space of the packaging and the outer side faces the outside.

Furthermore, as far as the terminology of the present invention is concerned, the wall that faces towards the observer when the side parts face towards him is called the front wall. On the contrary, the back wall is the wall that is not facing the observer when the side parts face him. The part that faces downward in the arrangement described above is called the bottom. The base is the part of the packaging made up of the front wall, the bottom, the back wall and, if available, the junction with the front/rear wall. The packaging may further comprise a lid.

The front wall comprises the side front wall panels as well as the body front wall panel. The rear wall comprises the side rear wall panels and the body rear wall panel. The background comprises the side part background panels and the body background panel. The lid comprises the side lid panels and the body lid panel. The side rear wall panels are hinged to the body rear wall panel, preferably by folding lines of the rear wall panel. The side part bottom panels and the body bottom panel are cut from each other, as are the side part front wall panels and the body front wall panel.

Advantageously, the front wall adhesive tabs are hinged by respectively a transversely oriented adhesive tab folding line on the body front wall panel and the bottom adhesive tabs are hinged by respectively an adhesive tab folding line starting from a near end of the bottom folding line that articulates the body bottom panel and runs obliquely with respect to it. However, it is also possible that the front wall adhesive tabs are hinged by respectively a transversely oriented adhesive tab folding line on the body side panel and that the bottom adhesive tabs are hinged by respectively a folding line of adhesive tab that starts from a near end of the bottom folding line that articulates the side part bottom panel and runs obliquely with respect to it in the side part bottom panel. Any combination of joints of the adhesive tabs on the side or body parts is also possible, provided that a fixed connection between the respective side and body part by means of an adhesive tab is possible. The bottom adhesive tabs are cut from the front wall adhesive tabs and separated by adhesive tab separation lines.

Particularly preferably, the bumper packaging has a lid next to the base. Thanks to this, it is possible to completely close the packaging and provide particularly good protection of the packaged product. This lid may be a separate piece that closes the base of the packaging according to the invention. Particularly preferably, the lid is formed by lid panels which are hinged by rear wall folding lines to the side rear wall panels and to the body rear wall panel. In this particularly preferred case, the cover is configured in one piece with the cutout according to the invention.

If the lid is a separate piece, the base may be a packaging according to the invention, which is closed with a conventional lid. Likewise, the lid may be formed by a packaging according to the invention and the base is a packaging as known from the state of the art.

In a particularly advantageous embodiment, the base and the lid are respectively formed by a packaging according to the invention, one packaging being slightly larger than the other, so that the two parts can be nested inside each other. In this way, it is possible to duplicate the rear wall and the front wall, which leads to a particularly stable packaging that offers particularly strong protection for the object to be packaged in the dimension in which it is particularly susceptible to damage due to its geometry.

Preferably, closing tabs are provided on at least one of the lid panels to close the lid. Thanks to this, the lid can be secured on the base to prevent inadvertent opening. A particularly secure closure is achieved if closure tabs are provided for the lid on both the body and the side parts of the packaging.

To close the lid, insertable lid tabs can advantageously be hinged on the side lid panels respectively. Another advantageous closing possibility provides that a lid closing tab is hinged to the body lid panel by means of a lid closing tab folding line. In another particularly suitable form, lid closing tabs, in particular in the form of a barbell, are provided for closing the lid, which are hinged on the side parts of the lid. To close the lid, these are inserted into corresponding front wall closing slots, which are respectively hinged to a front wall tab folding line by the front wall tabs on the side front wall panels. In particular, these last-mentioned closures represent a very simple type of closure, which is also very secure and prevents the lid from opening, even if it is not additionally secured by gluing.

In the packaging according to the invention, all front wall panels, i.e. the body front wall panel and the side front wall panels, preferably respectively have the same length IVWe in the transverse direction. The same applies to the length IRW of the rear wall panels, i.e. the body rear wall panel and the side rear wall panels, as well as to the length Ib of the bottom panels, i.e. body bottom panel and the side part bottom panels, and to the length I<d>of the lid panels, that is, the body lid panel and the side part lid panels.

Particularly preferably, the length IVW of the front wall panels and the length Irw of the rear wall panels are also equal. Also particularly preferably, alternatively or additionally, the length Ib of the bottom panels and the length Id of the lid panels are equal. This results in a bumper packaging with parallel walls. However, alternatively it is also possible that the front and rear walls of the body and/or side part(s) do not run parallel.

The rear wall of the side parts may be formed by a side part rear wall panel. However, it is also possible that the rear wall of the side parts is formed by several, preferably in particular two, rear side wall panels, which are connected to each other by folding lines. Providing more than one side rear wall panel allows for greater flexibility in the shape of the packaging. If a side front wall panel and a side rear wall panel are respectively provided, as well as a panel for connecting the rear wall and the front wall, a rectangle is obtained as the base surface for the side part. and the lateral part is parallelepiped. In the case of two side part rear wall panels arranged at an angle to each other and there being at the same time a side part front wall panel and a joining panel of the rear wall and the front wall, the base surface is a pentagon and the lateral part is a prism with a pentagonal base surface.

The front side wall and the rear side wall are preferably joined together in such a way that a completely closed packaging is created. Therefore, the side parts preferably each continue to have a joint, which is formed by a rear/front wall joint panel hinged on the rear side wall panel and a front/rear wall joint panel hinged on the side part front wall panel. These panels may overlap partially or preferably completely on the assembled packaging. They can be closed, for example, by gluing. Particularly preferably, the closure is carried out by fixing the front/rear wall connection panel to the rear side wall panel by means of a double closure.

For this purpose, in a particularly preferred embodiment, double side closure slots can be provided in the rear side wall panels and double side closures articulated by double side closure folding lines in the panels. front/rear wall joint. The double side closures engage into the double side closure slots, creating a very secure closure. Double closures have several advantages. On the one hand, they can be closed quite quickly, which represents an additional saving of time when assembling the packaging according to the invention. In addition, these closures are particularly stable and secure when closing. These latches do not open even when recoil forces are applied. Therefore, it is not necessary to additionally secure them, for example by means of adhesive tape.

To close the bottom of the side parts, insertable bottom tabs may be provided, which are hinged to the side part bottom panels, in addition to being arranged adjacent to the front/rear wall joining panels and separated from them. through separating lines of bottom insertable tabs. In order to seal the bottom and the rear wall in a tight manner at the side parts, corner folds can be provided between the side rear wall panels and the side bottom panels, which are respectively folded in the erected state of the packaging. through folding lines towards the interior of the packaging.

Handling of the packaging according to the invention can be further facilitated by providing handle punches on the body. With the help of this, not only can the packaging be grasped, but the user can also insert his hand into it. It has proven to be particularly practical in the application to provide on the rear body wall two handle punches at the same height and spaced apart from each other and on the front body wall a handle punch. However, any other number of handle punches or the attachment of handle punches to one or both side parts is also possible.

Handle punches can be produced in this way by complete punching from the cutout. Alternatively, a grip tab may be formed by not completely punching out the handle punch, remaining in an area attached to the cutout and being able to rotate around a grip tab folding line.

In a particularly advantageous embodiment, the handle punch can form part of a lid closure, with a lid closure tab being articulated in particular by a lid closure tab folding line on the body lid panel. , which has a lid handle punch, as well as a grip tab joined thereto by a grip tab folding line, forming the lid handle punch and the grip tab with a front wall handle punch of body a lid closure. A closure of this type is also possible for one or both side part(s), a lid closing tab with a lid handle punch and a gripping tab being articulated on the lid side part, which With a front wall handle die cut on the side part it forms a lid closure. In this regard, the gripping tab is advantageously designed not to completely punch out the handle punch, but rather to remain connected in one area to the lid and to be rotatable around a gripping tab folding line. Preferably, the gripping tab folding line is arranged on the side facing the lid closing tab. When the lid is closed, the lid handle punch and the body front wall handle punch are congruent. The gripping tab of the lid handle die cut can be pressed inwards, thus securing the lid in the packaging.

Such a configuration of the gripping tab on the front body wall has the additional advantage that a gripping possibility is predetermined for the user, which can be called a "theoretical gripping point". Without such a gripping possibility, the user would be tempted to grasp under the lid closing tab, which could result in undesired opening of the lid.

Particularly preferably, the bumper packaging according to the invention can be erected by unfolding the side parts around the rear wall fold lines into a partially assembled state from a pre-assembled folded state, in which the bottom panels and the front wall panels as well as the front/rear wall joining panels are folded 180° around bottom fold lines on the rear wall panels, the bottom adhesive tabs are folded 180° around the bottom fold lines adhesive tabs and the front wall adhesive tabs are folded 180° around the adhesive tab fold lines and the front side wall panels are folded 180° around rear wall fold lines on the rear wall panels side, as well as the front/rear wall joint panels are folded 180° on the rear body wall panel and the front body wall panel folded 180° on the rear body wall panel, there being a flat glued joint between the rear sides of the side part front wall panels and the front wall adhesive tabs and the rear sides of the side part bottom panels and the bottom adhesive tabs.

Therefore, the invention also relates to a pre-assembled bumper packaging, also called "pre-assembled blank" or simply "blank", formed by a cutout according to the invention, in which the bottom panels and the panels as well as, if available, the front/rear wall joint panels are folded around 180° bottom fold lines on the rear wall panels and the bottom adhesive tabs are folded 180° around the adhesive tab lines and the front wall adhesive tabs are folded 180° around the adhesive tab fold lines and the side portions are folded 180° onto the body, leaving the outer sides of the side front wall panels arranged on the front wall adhesive tabs and the front sides of the side bottom panels on the bottom adhesive tabs and being respectively fixedly joined.

By turning, as described above, the side parts outwards around the rear wall fold lines, the partially assembled bumper package is obtained. The side parts are already connected to the body both at the bottom and on the front and rear walls. To complete the base, therefore, you only have to close the respective joints from the front to the rear wall on the side parts. Thus, starting from the pre-assembled state, the bumper packaging according to the invention can be finished with few maneuvers. In the next stage, the bumper is placed in the packaging. Depending on the embodiment, either a separate lid is then placed or the lid panels are folded and the lid is secured to the base using the closures provided to close the packaging.

The bumper packaging according to the invention is therefore a semi-automatic packaging. The first stage of assembly, erecting the packaging with the front and rear wall, is carried out by gluing it on the pre-assembled only for unfolding the packaging.

The other necessary connections are made by insertion and/or gluing, preferably in particular by insertion. It is especially advantageous if the other connections are made by insertion. Specifically, in this case, the packaging according to the invention can be used several times. The packaging can be opened at the insertion joints without damage to the packaging. Once all insertion joints have been released, it can be easily folded back into the pre-made blank state by folding the side parts inwards around the rear wall fold lines and, if necessary, reused by erecting it. again.

Compared to conventional packaging cutouts, the packaging cutout according to the invention can be folded as a blank of a much smaller extent in length and width. This is due in particular to the arrangement of the folding lines. In the folded state, in the packaging blank the side parts are folded around the rear wall fold lines between the body part and the side parts on the body part, so that the dimensions of the blank correspond to those in the body area of the cutout. This significantly simplifies the handling of the blank. However, due to folding, the blank has a greater thickness, that is, up to six layers of material - respectively the front and rear walls of the body and the two side parts. However, this is more than offset by the smaller extension in width and length and the compactness associated with it. Specifically, this means that up to almost 30% more raw packaging pieces can be transported in a truck compared to the state of the art. Of course, it also takes up correspondingly less storage space.

In view of the fact that a large part of the necessary joints of the cutout parts already exist in the supplied state of the packaging, the number of steps to be carried out in the subsequent assembly of the packaging is considerably reduced, which leads to significant savings. of time mentioned at the beginning in the assembly, for which only 30 seconds are now needed in the packaging according to the invention.

In the present application, the packaging is called "bumper packaging" and is also described as such. Of course, other objects can also be packed freely in the packaging according to the invention. The packaging is especially suitable for any U-shaped object. It can be manufactured in any size. In a particularly preferred form, the two side parts have the same size and are fixed at the same angle on the body, so that a mirror-symmetrical packaging is created. However, it is also possible that the two lateral parts have different dimensions from each other and/or that they are arranged at different angles with respect to the body.

Finally, the present invention also relates to a method for the mechanical manufacture of a pre-assembled bumper packaging, which can be erected from a pre-assembled folded state to a partially assembled state, the manufacturing being carried out continuously on a manufacturing machine with cycles. of work integrated into it, which includes the following procedural stages:

(1) a cardboard or corrugated cardboard format is fed to a die-cutting station of the manufacturing machine to perform a first work cycle;

(2) in the first work cycle, a cutout in accordance with the invention of the bumper packaging is punched out of the cardboard or corrugated cardboard format;

(3) in a second work cycle carried out in a folding station, in a first partial stage, the bottom panels are first folded and with them the front wall panels articulated therein, as well as the joining panels of front/rear wall in 180° bottom fold lines over the rear wall panels and the rear/front wall joining panels and then, in a second partial step, the bottom adhesive tabs are folded 180° around the lines of the adhesive tabs and the front wall adhesive tabs are folded 180° around the adhesive tab folding lines;

(4) in a third work cycle, an adhesive is applied on a surface side of the cutout to all the adhesive tabs that form sticking points, that is, the bottom adhesive tabs and the front wall adhesive tabs;

(5) In a fourth work cycle carried out at a folding station, the cutout continues to be folded by folding the side parts 180° onto the body in such a way that a flat glued joint is created between the rear sides of the wall panels side panel and the front wall adhesive tabs and the rear sides of the side panel bottom panels and the bottom adhesive tabs and a pre-assembled folded bumper packaging is created, which can be erected into a partially assembled state by unfolding of the side parts around the rear wall folding lines.

Depending on the dimensions of the side parts in relation to the body, the side parts are folded in step (5), in this regard preferably one after the other, so that in the case of in the folded state a side part is at least partially on top of the other, it is possible to simply place one on top of the other.

Alternatively to applying the adhesive to the adhesive tabs, the adhesive may also be applied to corresponding points on the outer side of the side front wall panels and the side bottom panels. The only relevant thing is that a fixed connection can be created between the adhesive tabs and the corresponding area of the side front wall panels and the side bottom panels.

With the method according to the invention, a very simple production of the bumper packaging blanks is possible. Since all the adhesive tabs are on one side of the cutout, the adhesive can be applied in a single step. For example, four glue nozzles can be provided, which in this case allow four-point gluing at the same time.

In just a few steps, cut and configure the fold lines, fold twice, i.e. fold around the bottom fold lines and then fold the adhesive tabs around the adhesive tab lines, apply the adhesive and return. By folding the two side parts one after the other so that they remain in the body, the blank piece of the bumper packaging is formed according to the invention. The latter can in turn be deployed by simply folding its side parts outwards.

The dependent claims refer to the mentioned configurations of the invention and to other recommended and advantageous configurations. Only particularly recommended and advantageous embodiments will be described in more detail in the following description of the embodiment examples shown in the schematic drawing. Each individual or detailed configuration described within the framework of an example embodiment is to be understood as a structurally independent detailed example for other embodiments and configurations not described or not completely described that fall within the scope of the invention.

The side parts 4 are respectively formed by the side part front wall panels 33, 37, the side part rear wall panels 12, 13, 17, 18 and the side part bottom panel 23, 27. The side part rear wall panels 12 and 13 or 17 and 18 may be divided by rear wall fold line 112 or 118, although they may also be configured as a single panel, i.e., rear wall fold lines 112, 118 are optional. When these rear wall folding lines 112, 118 are provided, the packaging is more flexible.

The body front wall panel 35 and the body bottom panel 25, as well as the side part front wall panels 33, 37 and the side part bottom panels 23, 27 are articulated with each other by folding lines of front wall 300 oriented longitudinally. The front body wall panel 25 and the rear body wall panel 15, as well as the side part bottom panels 23, 27 and the rear side part wall panels 12, 13, 17, 18 are hinged to each other by longitudinally oriented background folding lines 200. The lid panels 4, 40, namely the body lid panel 45 and the side lid panels 42, 43, 47, 48, are hinged by rear wall fold lines 100 oriented longitudinally on the wall panel rear of body 15 and in the rear side wall panels 12, 13, 17, 18.

In the shown embodiment, all the front wall panels 30, that is, the body front wall panel 35 and the side front wall panels 33, 37 respectively have the same length I<vw>in the transverse direction. The same applies to the length I<rw>of the rear wall panels 10, that is, the body rear wall panel 15 and the side part rear wall panels 12, 13, 17, 18, as well as the length I<b>of the bottom panels 20, that is, of the body bottom panel 25 and the side part bottom panels 23, 27, and to the length I<d>of the lid panels 4, 40, that is, the body lid panel 45 and the side part lid panels 42, 43, 47, 48.

Also the length Ivw of the front wall panels 30 and the length Irw of the rear wall panels 10 are the same, as are the length I<b>of the back panels 20 and the length I<d>of the panels of the lid 40. Thus, a bumper packaging 1 is obtained in which both the walls of the lid 4, 40 and the bottom 20, as well as the walls of the front wall 30 and rear wall 10 run parallel. However, alternatively it is also possible that the front and rear walls of the body and/or side part(s) are not configured parallel.

The side portion rear wall panels 13, 17 are hinged to the body rear wall panel 15 by transversely oriented rear wall panel fold lines 114, 116.

The side part lid panels 42 and 43, as well as 47 and 48, are also separated from each other by transversely oriented lid panel separation lines 442, 448, just as the side part lid panels 43 and 47 are respectively separated from the body lid panel 45 by lid panel separation lines 444 and 446.

In addition, handle punches 91, 93, 94, 95 are provided in the cutout. With the help of this, not only can the packaging be grasped, but the user can also insert his hand into it. In the cut-out shown in Figure 2, two handle punches 94, 95 are provided on the rear body wall panel 15 at the same height and at a distance from each other and one punch is provided on the front body wall panel 35. of handle.

The handle punch 93 in the body front wall panel 35 is completely punched out of the cutout 2. In contrast, the handle punches 91, 94 and 95 are formed by not being completely punched out, but remain attached in an area with the cutout 2. In this way, gripping tabs 92 are formed, which can be rotated around the gripping tab folding lines 900.

Front wall adhesive tabs 53, 54 are hinged to the body front wall panel 35 respectively by means of a transversely oriented adhesive tab folding line 353, 354. Furthermore, bottom adhesive tabs 51, 52 are articulated to the body bottom panel 25 by means of respectively an adhesive tab folding line 251, 252, which start from a near end of the bottom folding line 200 that articulates the panel. of body bottom 25, running obliquely with respect to it. The bottom adhesive tabs 51,52 are cut from the front wall adhesive tabs 53, 54 and separated by adhesive tab separation lines 551, 552.

For the prefabrication of the blank 9, in this cutout 2, in a first partial step, first the bottom panels 23, 25, 27 and with them the front wall panels 33, 35, 37 articulated in these, as well as the front/rear wall panels 31, 39 on the bottom fold lines 200 180° on the rear wall panels 12, 13, 15, 17, 18, as well as the rear wall/front wall joining panels 11, 19. Next, in a second partial step, the bottom adhesive tabs 51, 52180° are folded around the adhesive tab lines 251,252 on the outer side of the body front wall panel 35 and the wall adhesive tabs front 53, 54 are folded 180° around the folding lines of adhesive tabs 353, 354 on the outer side of the body bottom panel 25. Thanks to this, the adhesive tabs 51, 52, 53, 54 are presented again with the inner side of the cutout facing outward. In a next step, adhesive is applied to the adhesive tabs 51, 52, 53, 54.

Alternatively, the adhesive may also be applied to the outer side areas of the side front wall panels 33, 37 and the side bottom panels 23, 27 that correspond to the adhesive tabs 51, 52, 53, 54. The only relevant thing is that a fixed connection can be created between the adhesive tabs 51, 52, 53, 54 and the corresponding area of the side front wall panels 33, 37 and the side bottom panels 23, 27 .

In the next step, the two side parts 6 are successively folded by the rear wall panel folding lines 114 and 116180° onto the body 5. The pre-folded, prefabricated blank 9 shown in Figure 3 is obtained.

In the case of the blank 9 shown in Figure 3, first the left side part 6b had been folded onto the body 5 and then the right side part 6a. By folding the side parts 6 onto the body 5, fixed joints are formed between the front wall adhesive tabs 53, 54 and the corresponding area of the side part front wall panels 33, 37, as well as between the front wall adhesive tabs 53, 54. bottom 51, 52 and the side part bottom panels 23, 27.

The dimensions of the cutout 9 correspond to those of the rear body wall panel 15 and the body lid panel 45 which is hinged in this embodiment, as well as the lid closure tab 71, which is itself hinged. in the body lid panel 45. The rear body wall panel 15 and the body lid panel 45 cannot be seen in Figure 3, since they are covered by the rear side wall panels 13, 14, 16, 17 and the side cover panels 42, 43, 47, 48.

If the two side parts 6, 6a, 6b are folded outwards again, the blank 9 stands as semi-finished bumper packaging 1, because fixed connections between the front wall adhesive tabs 53, 54 have been created. body front wall parts 35 and the side part front wall parts 33, 37 and by means of the bottom adhesive tabs 51, 52 fixed joints between the body bottom panel 25 and the side part bottom panels 23, 27. In this The openings between the front wall 30 and the rear wall 10 must first be closed. This is done by overlapping the front/rear wall joining panel 31, 39 with the rear/front wall joining panel 11, 19 and closing by means of the double closure of the side part 73, 75.

Figure 4 shows the fully erected bumper packaging 1 in the state of use with the lid 4, 40 open in a perspective view from the front. Base 3 is closed. All lid panels 42, 43, 45, 47, 48 are open. In this figure 4 the rear wall 10 can also be seen. In this state of the packaging the product to be packaged, in particular a bumper, can be placed in the packaging.

To close the lid 4, 40, all lid panels 42, 42, 45, 47, 48 as well as the front wall tabs 67, 68 are folded inwards until they form an angle of 90° or approximately 90° with the front wall 30 or the rear wall 10. At this time the lid 4, 40 is secured in the base 3, the lid insertable tabs 61, 62 being inserted into the base 3, the lid closing tabs 65, 66 being inserted in the front wall closure slots 76, 77 and an additional closure is formed by engaging the lid closure tab 71 and the body front wall panel 35.

In this last-mentioned closure, the handle punch 91 forms part of a lid closure, namely a lid closure tab 71 being hinged to the body lid panel 45 by a lid closure tab folding line. 700, which has a lid handle punch 91, as well as a grip tab 92, the lid handle punch 91 and the grip tab 92 forming a lid closure 71, 91, 92, 93 with a handle punch of body front wall 93. In this regard, the grip tab 92 is configured not to completely punch out the handle punch 91, but rather to remain attached in an area with the lid 40 and can be rotated around a tab folding line of grip 900. In this regard, the tab folding line of the grip 900 is arranged on the side facing the closing tab of the lid 71. When the lid 4 is closed, the lid handle punch 91 and the handle punch of front wall of body 93 are congruent. The gripping tab 92 can be pressed inwards and thus secures the lid 4 in the packaging 1.

The closed bumper packaging 1 shown in Figure 1 is obtained.
