Description

The present invention relates to a bumper packaging made from a blank of flexible cardboard or corrugated cardboard material, comprising a cuboid body or a basic shape of a prism, which has a body front wall field, a body back wall field and a body floor field, as well as two cuboid or a basic shape arranged on opposite sides of the body a prism or a truncated pyramid having side parts, which each have a side part front wall field, a side part back wall field and a side part bottom field, the fuselage front wall field and fuselage floor field as well as side part front wall fields and side part base fields, preferably via longitudinal front wall fold lines, are hinged to one another, wherein the side back panel and the side part front wall with the fuselage back panel and the front wall panels each form an obtuse angle. The invention also relates to a blank for a bumper packaging made of flexible cardboard or corrugated cardboard material, the blank in a row at least three rectangular rear wall panels which are hinged to one another in the blank with transverse rear wall fold lines, at least one rear wall panel being a fuselage rear wall panel and at least two rear panel panels forming two side panel rear panel panels which are hinged to the fuselage rear wall panel via rear wall folding lines, at least partially cut free from one another, which are hinged to the rear wall panels with longitudinally directed floor folding lines in the blank, and at least three front wall panels which are hinged to the floor panels with longitudinal front wall folding lines in the cut, with at least two front wall panels two side part front wall panels are, as well as a method for the machine production of a pre-assembled bumper packaging.

Bumper packaging is well known. Bumpers are essentially U-shaped with connecting legs that are wide in relation to the two side legs. Because of their shape and size, they are bulky. Since they are also quite delicate and unstable, it is important to protect them well for transport and storage. The packaging of the bumpers is therefore of great importance. On the other hand, in view of the foregoing, packing bumpers is not trivial. One way of packing is in the DE 202 08 522 U1 described. The packaging described there consists of two carrier strips that are connected to one another by means of a connecting web and at least one connecting tab. This packaging adapts very well to the shape of the bumper. However, it only ensures that the bumper is partially covered, so that it does not offer full protection and is particularly unsuitable for bumpers that have already been painted.

In addition, bumpers were packed in box-shaped cardboard boxes. Such packaging is not adapted to the shape of the bumpers, which leads to problems. Apart from the fact that the material requirements and in particular the volume of the packaging make transport and storage cost-intensive, the large empty space that such packaging has when filled often leads to deformations and thus damage to the packaging.

For this reason, packaging was developed that completely surrounds the bumper in a stable manner and is adapted to the U-shape of the bumper. Such bumper packaging, as described in the preamble of claim 1, are for example from JP 2007-050920 A , the CN 202072154 U , the DE 10 2014 100 779 A1 or the EP 2 861 500 A1 known. They usually consist of a blank made of cardboard or corrugated cardboard material, which is unfolded and plugged together to form the finished bumper packaging. Required connections of parts that are not already articulated to one another in the cut are mostly effected by plug-in tabs; gluing is also possible, with plugging being preferred. Depending on the type of packaging, it is also common to use adhesive tape to secure one or more of the plug-in tab connections to prevent the tab from slipping out.

The construction of such packaging is, however, very difficult and complex and, even if it is basically possible for one person to assemble it, it is better to have two people, since several parts have to be held and inserted at the same time. This causes high process costs, which are added to the price of the packaged bumper and therefore have to be borne by the customer.

Another aspect of the packaging is the space it takes up when it is delivered. Due to the size of the packaging, the blanks are also of considerable size. The nature of the cut does not allow this, or only to a very limited extent to be reduced in terms of its surface area by folding for transport, which means that the blanks are awkward to handle.

The present invention was therefore based on the object of providing bumper packaging which solves the problems outlined above, which can be assembled simply and in a shorter time and preferably by one person alone. In addition, the packaging should be collapsible in the delivery state to a size that is smaller in its area than the usual packaging and simplifies handling.

This object is achieved according to the invention by a bumper packaging of the type mentioned, in which each side part front wall panel is fixedly connected to the fuselage front wall panel by means of a front wall adhesive flap and each side part floor panel is fixedly connected to the fuselage floor panel by means of a floor panel adhesive flap.

“Fixedly connected by means of an adhesive flap” in the context of the invention means that the adhesive flap overlaps the field to which it is fixedly connected and is permanently connected to it, preferably by gluing. But other permanent connections such as stapling or riveting are also possible.

When "gluing" is used in the context of the present invention, all known adhesives come into consideration, such as in particular glue, two-component glue or hot melt glue, glue being particularly preferred. Different adhesives can also be used for different bonds, depending on the desired properties.

"From a blank" in the context of the present invention means that the blank is preferably formed in one piece and the individual fields and tabs of the blank are formed by fold lines via which the respective fields and tabs are also linked to one another. However, the present invention also includes blanks which are composed of several parts, the parts being firmly connected to one another in a manner other than folding lines, for example by means of an adhesive flap connection.

"Articulated to one another" in the context of the invention means that two parts are connected to one another. This can be done via tabs, in particular by means of gluing and adhesive tabs. Articulation via fold lines is particularly advantageous.

The object is also achieved by a blank for bumper packaging of the type mentioned at the beginning, in which a floor panel is a fuselage floor panel, which links two floor adhesive flaps by means of a respective adhesive flap fold line, which start from a near end of the floor fold line which links the fuselage floor panel and runs obliquely, and wherein two floor panels are side part floor panels which are each adjacent to one of the floor adhesive flaps, and one front wall panel is a fuselage front wall panel which links two front wall adhesive flaps in each case by means of a transversely directed adhesive flap fold line.

Such a bumper packaging according to the invention or such a blank according to the invention can be erected very easily and completely by just one person. The time required for setting up the packaging is significantly reduced compared to the time required for erecting a conventional bumper packaging, to about 30 seconds for a bumper packaging according to the invention. This significantly reduces the personnel costs for the construction, which also greatly reduces the price of the packaging overall. In particular, the fact that side part front wall panels and fuselage front wall panel as well as side part floor panels and fuselage floor panel are fixedly connected to one another by means of adhesive flaps, reduces the number of necessary plug connections that have to be closed to assemble the packaging, which leads to a noticeable time saving during assembly.

A blank according to the invention has an inside and an outside. When the packaging is set up, the inside faces the interior of the packaging, the outside faces outwards.

As far as the terminology of the present invention is concerned, the front wall refers to the wall which faces the viewer when the side parts point towards him. Conversely, the rear wall is the wall that faces away from the viewer when the side panels point at him. The part that points downward in the above-described arrangement is referred to as the bottom. The basis is the front wall, floor, rear wall and, if available, Part of the packaging formed from the front / rear wall connection. The packaging can further comprise a lid.

The front wall comprises the side part front wall fields and the fuselage front wall field. The rear wall comprises the side part rear wall fields as well as the fuselage rear wall field. The floor comprises the side part floor panels and the fuselage floor panel. The cover includes the side panel cover fields and the fuselage cover field. The side part rear panel panels are hinged to the fuselage rear panel panel, preferably via rear panel panel fold lines. Side part floor fields and fuselage floor field are cut free from one another, as are side part front wall fields and fuselage front wall field.

Advantageously, the front wall adhesive flaps are each linked to the fuselage front wall panel by means of a transversely directed adhesive flap fold line and the floor adhesive flaps are each linked to the fuselage floor panel by means of a respective adhesive flap fold line that starts at a near end of the floor fold line that connects the fuselage floor panel and runs obliquely. However, it is also possible that the front wall adhesive flaps are linked to the body side panel by means of a transversely directed adhesive flap fold line and the bottom adhesive flaps are linked to the side panel floor panel by means of a respective adhesive flap fold line, which starts at a near end of the floor fold line linking the side panel floor panel and runs obliquely. Any combinations of articulations of the adhesive flaps to the side or body parts are also possible, as long as a fixing connection between the respective side and body part is possible via an adhesive flap. The bottom adhesive flaps are cut free from the front wall adhesive flaps and separated by adhesive flap separating lines.

The bumper packaging particularly preferably has a lid in addition to the base. This enables the packaging to be completely closed and the packaged goods to be protected particularly well. This lid can be a separate part that closes the base of the packaging according to the invention. The cover is particularly preferably formed from cover fields which are hinged to the side part rear wall fields and the fuselage rear wall field via rear wall fold lines. In this particularly preferred case, the cover is formed in one piece with the blank according to the invention.

If the lid is a separate part, the base can be a package according to the invention which is closed with a conventional lid. Likewise can the lid can be formed from a packaging according to the invention and the base is a packaging as is known from the prior art.

In a particularly advantageous embodiment, the base and cover are each formed from a packaging according to the invention, one packaging being slightly larger than the other, so that the two parts can be pushed into one another. In this way, it is possible to double the rear wall and front wall, which leads to a particularly stable packaging that offers particularly strong protection for the item to be packaged in the dimension in which it is particularly susceptible to damage due to its geometry.

Closing tabs are preferably provided on at least one of the cover panels to close the cover. In this way, the cover on the base can be secured against unintentional opening. A particularly secure closure is achieved if closure flaps are provided for the cover both on the body and on the side parts of the packaging.

To close the cover, cover plug-in tabs can advantageously be hinged to the side part cover fields. Another advantageous closure option provides that a cover closure tab is hinged to the fuselage cover panel via a cover closure tab fold line. In another particularly suitable shape, cover closure tabs, in particular in the form of a dumbbell, are provided for closing the cover, which are hinged to cover side parts. To close the cover, these are inserted into corresponding front wall closure slots which are each hinged to the side part front wall panels in a front wall flap fold line over the front wall flaps. The latter closures in particular represent a very simple type of closure which is also very secure and ensures that the cover does not pop open, even if there is no additional securing by gluing.

In the case of the packaging according to the invention, all the front wall fields, that is to say the fuselage front wall field and the side part front wall fields, preferably each have the same length l _VW in the transverse direction. The same applies with regard to the length l _{RW of} the rear wall fields, i.e. of the fuselage rear wall field and side part rear wall fields, as well as with regard to the length l _{B of} the floor fields, i.e. of the fuselage floor field and side part floor fields, and with regard to the length l _{D of} the cover fields, that is to say of the trunk cover field and the side cover fields.

_{The length l VW of} the front wall fields and the length I _{RW of} the rear wall fields are also particularly preferably the same. Furthermore, as an alternative or in addition, the length l _B of the bottom panels and the length l _{D of} the cover panels are particularly preferably the same. A bumper package with parallel walls is thus obtained. Alternatively, however, 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 can be formed from a side part rear wall field. However, it is also possible that the rear wall of the side parts consists of several, preferably in particular two, side part rear wall fields which are connected to one another via fold lines. The provision of more than one side panel back panel provides greater flexibility in the shape of the package. If a side part front wall field and a side part rear wall field as well as a field for connecting the rear wall and front wall are provided, the base area for the side part is a rectangle and the side part is cuboid. In the case of two side part rear wall fields arranged at an angle to one another with a side part front wall field and a connecting field between the rear wall and front wall at the same time, the base area is a pentagon and the side part is a prism with a pentagonal base area.

Side part front wall and side part rear wall are preferably connected to one another in such a way that an all-round closed packaging is created. The side parts therefore preferably each have a connection which is formed from a rear / front wall connection field articulated on the side part rear wall field and a front / rear wall connection field articulated on the side part front wall field. When the packaging is built up, these fields can partially or preferably completely overlap. They can be closed, for example, by gluing. Closing is particularly preferably carried out in that the front / rear wall connection field is fastened to the side part rear wall field by means of a double closure.

For this purpose, in a particularly preferred embodiment, side part double locking slits can be provided in the side part rear wall fields and side part double locks can be provided via side part double locking fold lines on the front / rear wall connection fields. The side part double locks are inserted into the side part double lock slots hooked, creating a very secure closure. Double locks have several advantages. On the one hand, they can be closed very quickly, which means a further saving in time when assembling the packaging according to the invention. In addition, these closures are particularly stable and secure. Even when restoring forces act, these closures do not open. It is therefore not necessary to additionally secure them, for example with adhesive tape.

To close the bottom of the side parts, bottom push-in flaps can be provided which are hinged to the side part bottom panels and are arranged adjacent to the front / rear wall connection panels and are separated from these by bottom push-in flap dividing lines. To seal the bottom and rear wall on the side parts, corner folds can be provided between side part rear wall panels and side part bottom panels, which are folded into the interior of the packaging via fold lines in the erected state of the packaging.

The handling of the packaging according to the invention can be further facilitated in that handle punchings are provided in the body. With the help of this, the packaging can not only be grasped, the user can also reach into it. It has proven to be particularly practical to use two handle punchings in the rear wall in the fuselage at the same height and at a distance from one another and in the front wall in the fuselage one handle punching. However, any other number of handle punchings or the attachment of handle punchings in one or both side parts is also possible.

The handle punchings can be done by completely punching out the blank. Alternatively, a tab can be formed in that the punched handle is not completely punched out, but instead remains connected to the blank in one area and can be pivoted about a tab fold line.

In a particularly advantageous embodiment, the handle punching can form part of a lid closure, namely in that a lid closure tab is hinged in particular to the body lid field via a lid closure tab fold line, which has a lid handle punching and a grip tab connected to this via a handle flap fold line, the cover handle punching and grip tab with a body front panel handle punching a lid lock form. A Such a closure is also possible for one or both side part (s) in that a lid closure tab with lid handle punching and grip tab is hinged to the cover side part, which forms a lid lock with a side part front wall handle punching. The grip tab is advantageously formed in that the handle punching is not completely punched out, but rather remains connected in an area on the cover and can be pivoted about a grip tab fold line. The handle flap fold line is preferably arranged on the side facing the lid closure flap. If the cover is closed, the cover handle punching and the fuselage front wall handle punching come into cover. The grip tab of the lid handle punch can be pressed inwards, thus securing the lid to the packaging.

Such a design of the grip tab in the front wall of the fuselage has the further advantage that a grip option is provided for the user, which can be referred to as the "target grip point". Without such a grip, the user would be tempted to reach under the lid closure flap, which could result in an undesired opening of the lid.

The bumper packaging according to the invention can particularly preferably be made from a collapsed pre-assembled state in which the bottom panels and front wall panels as well as front / rear wall connection panels are folded by 180 ° onto the rear wall panels at bottom fold lines, the bottom adhesive flaps by 180 ° around the adhesive flap lines and the front wall adhesive flaps by 180 ° around the adhesive flap fold lines are folded and the side part front wall panels and front / rear wall connection fields folded around rear wall fold lines by 180 ° onto the side part rear wall fields and front / rear wall connection fields are folded by 180 ° onto the fuselage rear wall floor field and fuselage front wall field folded by 180 ° onto the fuselage rear wall field, whereby a flat adhesive connection between the rear sides of the side part front wall panels and the front wall adhesive panels the back of the side panel bottom panels and the bottom adhesive flaps can be erected in a partially assembled state by opening the side panels around the rear panel fold lines.

The invention therefore also relates to a pre-assembled bumper packaging, also referred to as a "pre-assembled blank" or "blank" for short, consisting of a blank according to the invention in which the bottom panels and front panel panels and - if available - front / rear panel connection panels are attached Bottom fold lines by 180 ° on the rear wall panels and the bottom adhesive flaps by 180 ° around the adhesive flap lines and the front wall adhesive flaps by 180 ° around the adhesive flap fold lines and the side parts are folded by 180 ° on the fuselage, the outer sides of the side part front wall panels on the front wall adhesive flaps and the front sides of the Side part floor panels lie on the floor adhesive tabs and are each connected in a fixed manner.

If, as described above, the side parts are pivoted outwards around the rear wall fold lines, the bumper packaging that has already been partially assembled is obtained. The side parts are already connected to the fuselage on the floor as well as on the front and rear walls. To complete the base, all you have to do is close the respective connections from the front to the rear wall on the side panels. The bumper packaging according to the invention can thus be completed in a few simple steps from the pre-assembled state. In the next step, the bumper is put into the packaging. Depending on the design, either a separate lid is then put on or the lid panels are folded and the lid is secured to the base by means of the closures provided in order to close the packaging.

The bumper packaging according to the invention is therefore a semi-automatic packaging. The first assembly step, the erection of the packaging with the front and rear walls, takes place solely by unfolding the packaging due to the adhesive in the pre-assembly.

The other required connections are made by plugging and / or gluing, preferably in particular by plugging. It is particularly advantageous if the other connections are made by means of plugging. In this case, the packaging according to the invention can be used several times. The packaging can be opened at its plug connections without damaging the packaging. After releasing all plug connections, it can easily be folded back into the state of the pre-assembled blank by folding the side parts inwards around the rear wall folding lines and re-erecting them if necessary.

Compared to the blanks of conventional packaging, the blank of the packaging according to the invention can be made into a blank of very much smaller dimensions be merged in length and width. This is due in particular to the arrangement of the fold lines. In the collapsed state, the side parts in the packaging blank 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 of the body area of the blank. This significantly simplifies the handling of the blank. In view of the folding, the blank has a greater thickness, namely up to six layers of material - each of the front and rear walls of the fuselage and the two side parts. However, this is more than offset by the smaller expansion in width and length and the associated compactness. This leads to the fact that up to 30% more packaging blanks can be transported in a truck compared to the state of the art. There is of course a corresponding saving in space for storage.

In view of the fact that a large part of the required connections of the parts of the blank already exists in the delivery condition of the packaging, the number of steps to be carried out in the further assembly of the packaging is significantly reduced, which leads to the relevant time savings mentioned above during assembly, for the Packaging according to the invention are only required 30 seconds, leads.

The packaging is referred to as "bumper packaging" in the present application and is also described as such. Of course, any other objects can also be packaged in the packaging according to the invention. The packaging is particularly suitable for any objects that have a U-shape. It can be made in any size. In a particularly preferred form, the two side parts are the same size and are attached to the body at the same angle, so that a mirror-symmetrical packaging is created. However, it is also possible that the two side parts have different dimensions from one another and / or are arranged at different angles to the fuselage.

Finally, the present invention also relates to a method for the machine production of a pre-assembled bumper packaging which can be erected from a collapsed pre-assembled state to a partially assembled state, the production being carried out continuously in a manufacturing machine with operations integrated therein, comprising the following method steps:

1. (1) a cardboard or corrugated cardboard format is fed to a punching station of the manufacturing machine for performing a first operation;
2. (2) In the first step, a bumper packaging blank according to the invention is punched out of the cardboard or corrugated cardboard format;
3. (3) In a second work step carried out in a folding station, in a first sub-step, first the floor panels and with them the front wall panels and front / rear wall connection panels attached to them are folded by 180 ° onto the rear panel panels and rear panel / front panel connection panels on floor fold lines and then in one second sub-step, the bottom adhesive flaps folded by 180 ° around the adhesive flap lines and the front wall adhesive flaps by 180 ° around the adhesive flap fold lines;
4. (4) In a third operation, an adhesive is applied to one surface side of the blank on all adhesive tabs forming adhesive points, that is to say the bottom adhesive tabs and the front wall adhesive tabs;
5. (5) In a fourth work step carried out in a folding station, the blank is further folded by folding the side parts by 180 ° onto the body in such a way that a flat adhesive connection between the rear sides of the side part front wall panels and the front wall adhesive flaps and the rear sides of the side part floor panels and the floor adhesive flaps and a Combined, pre-assembled bumper packaging is created, which can be erected in a partially assembled state by opening the side panels around the rear wall folding lines.

Depending on the dimensions of the side parts in relation to the fuselage, the side parts are preferably folded over in step (5) one after the other, so that if one side part is at least partially on top of the other in the folded state, they can be laid on top of one another without any problems.

As an alternative to applying the adhesive to the adhesive tabs, the adhesive can also be applied to the corresponding points on the outside of side part front wall panels and side part bottom panels. Relevant is just that a fixed connection between adhesive flaps and the corresponding area of side part front wall fields and side part bottom fields can be created.

With the method according to the invention, a very simple production of the bumper packaging blanks is possible. Since all the adhesive flaps are on one side of the blank, the adhesive can be applied in a single step. For example, four glue nozzles can be provided, which then allow glueing at four points at the same time.

In just a few steps, cutting and forming the folding lines, double folding, namely folding around the bottom fold lines and then folding the adhesive flaps around the adhesive flap lines, applying the adhesive, and folding the two side parts one after the other onto the fuselage, the blank of the bumper packaging according to the invention is formed . The latter, in turn, can be unfolded by simply flipping its side panels outwards.

The subclaims are directed to the mentioned and other expedient and advantageous refinements of the invention. Only particularly expedient and advantageous forms of embodiment and options are described in more detail with reference to the following description of the exemplary embodiments shown in the schematic drawing. Each individual or detailed design described within an exemplary embodiment is to be understood as a structurally independent detailed example for other designs and designs that are not or not fully described and that fall under the invention.

Fig. 1 shows a bumper packaging 1 according to the invention in the assembled state with the lid 4 closed in a perspective view. The bumper packaging 1 consists of a cuboid body 5 and two prism-shaped side parts 6 with a pentagonal base, which connect to the two sides of the body 5 and enclose an obtuse angle with it. The two side parts 6 have the same extent and the same angle to the fuselage 5, so that the bumper packaging 1 is designed with mirror symmetry.

In Fig. 1 The front wall 30 of the bumper packaging 1 can essentially be seen. Reference numeral 18 denotes a side panel rear panel which is part of the rear panel 10. Rear wall 10, front wall 30 and the in Fig. 1 Bottoms 20, which cannot be seen from the perspective, form the base 3 of the packaging 1. The packaging 1 is closed by the lid 4, which in this embodiment is formed integrally with the base 3. For better handling, the packaging 1 has a handle punching 91, 93 on the fuselage front wall 35, which is formed in the fuselage front wall 35 and cover closure flap 71.

Fig. 2 shows a blank 2 according to the invention for a bumper packaging 1 in a plan view of the inside of the blank. The blank 2 consists on the one hand of front wall 30, base 20 and rear wall 10, which together form the base 3 of the packaging 1, and in this embodiment of the lid 40, which is formed integrally with the base 3, so that the entire bumper packaging 1 from a blank 2 is formed. In another perspective, the packaging 1 is formed from the body 5 and side parts 6.

Fuselage 3 is formed from fuselage front wall field 35, fuselage rear wall field 15 and fuselage floor field 25 and fuselage cover field 45. The side parts 4 are each formed from side part front wall fields 33, 37, side part rear wall fields 12, 13, 17, 18 and side part floor fields 23, 27 and 18 can be subdivided by rear wall fold lines 112 and 118, respectively, but can also be designed as a field, ie the rear wall fold lines 112, 118 are optional. If these rear wall fold lines 112, 118 are present, the packaging is more flexible.

Fuselage front wall panel 35 and fuselage floor panel 25 as well as side part front wall panels 33, 37 and side part floor panels 23, 27 are articulated to one another via longitudinally directed front wall fold lines 300. Fuselage floor field 25 and fuselage rear wall field 15 as well as side part floor fields 23, 27 and side part rear wall fields 12, 13, 17, 18 are hinged to one another via longitudinal bottom fold lines 200. The fields of cover 4, 40, namely body cover field 45 and side cover fields 42, 43, 47, 48, are hinged to body rear wall field 15 and side cover rear wall fields 12, 13, 17, 18 via longitudinal rear wall fold lines 100.

In the embodiment shown, all fields of the front wall 30, that is to say the fuselage front wall field 35 and the side part front wall fields 33, 37 each have the same length l _VW in the transverse direction. The same applies with regard to the length l _{RW of} the fields of the rear wall 10, i.e. the fuselage rear wall field 15 and side part rear wall fields 12, 13, 17, 18 as well as with regard to the length l _{B of} the fields of the floor 20, i.e. of the fuselage floor field 25 and side part floor fields 23, 27, and with regard to the Length l _{D of} the fields of cover 4, 40, that is of body cover field 45 and side cover fields 42, 43, 47, 48.

The length l _{VW of} the fields of the front wall 30 and the length l _{RW of} the fields of the rear wall 10 are also the same, as is the length l _{B of} the fields of the base 20 and the length l _{D of} the fields of the cover 40. A bumper packaging 1 is thus obtained , in which both the walls of cover 4, 40 and base 20 and the walls of front wall 30 and rear wall 10 run parallel. Alternatively, however, it is also possible for the front and rear walls of the body and / or side part (s) not to be parallel.

The in Fig. 2 The cut shown, two handle punchings 94, 95 are provided in the fuselage rear wall field 15 at the same height at a distance from one another and a handle punching is provided in the fuselage front wall field 35.

The handle punch 93 in the fuselage front wall field 35 is completely punched out of the blank 2. Handle punchings 91, 94 and 95, on the other hand, are formed in that they are not punched out completely, but rather remain connected to the blank 2 in one area. In this way, tabs 92 are formed which can be pivoted about tab fold lines 900.

Front wall adhesive flaps 53, 54 are articulated to the fuselage front wall panel 35 by means of a transversely directed glue flap fold line 353, 354. In addition, adhesive bottom flaps 51, 52 are articulated to the fuselage floor field 25 by means of a respective adhesive flap fold line 251, 252, which extends from a near end of the floor fold line 200 that connects the fuselage floor area 25 and runs obliquely. The bottom adhesive tabs 51, 52 are cut free from the front wall adhesive tabs 53, 54 and separated by adhesive tab separating lines 551, 552.

To pre-assemble the blank 9 in this blank 2, in a first partial step, the bottom panels 23, 25, 27 and with them the front wall panels 33, 35, 37 and front / rear wall connection panels 31, 39 linked to them are rotated 180 ° at the bottom fold lines 200 folded onto the rear wall panels 12, 13, 15, 17, 18 and rear wall / front wall connection panels 11, 19. Then, in a second sub-step, the bottom adhesive flaps 51, 52 are folded by 180 ° around the adhesive flap lines 251, 252 on the outside of the fuselage front wall panel 35 and the front wall adhesive flaps 53, 54 are folded by 180 ° around the adhesive flap fold lines 353, 354 on the outside of the fuselage floor panel 25. As a result, the adhesive flaps 51, 52, 53, 54 are again present with the inside of the blank pointing outwards. In a next step, adhesive is applied to the adhesive flaps 51, 52, 53, 54.

Alternatively, the adhesive can also be applied to the areas on the outside of the side part front wall panels 33, 37 and side part bottom panels 23, 27 that correspond to the adhesive flaps 51, 52, 53, 54. It is only relevant that a fixed connection between adhesive flaps 51, 52, 53, 54 and the corresponding area of side part front wall fields 33, 37 and side part bottom fields 23, 27 can be created.

In the next step, the two side parts 6 are successively folded over the rear panel fold lines 114 and 116 by 180 ° onto the body 5. The result is the pre-folded, prefabricated blank 9, which is shown in Fig. 3 is shown.

The in Fig. 3 The blank 9 shown was initially the left side part 6b folded onto the body 5, then the right side part 6a. By folding the side parts 6 over onto the fuselage 5, the fixed connections between the front wall adhesive flaps 53, 54 and the corresponding area of side part front wall fields are made 33, 37 and between floor adhesive flaps 51, 52 and side part floor panels 23, 27.

The dimensions of the blank 9 correspond to those of the fuselage rear wall field 15 and the fuselage cover field 45 articulated in this embodiment, as well as the cover closure tab 71, which is in turn articulated on the fuselage cover field 45 Fig. 3 not visible because they are covered by the side part rear wall fields 13, 14, 16, 17 and side part cover fields 42, 43, 47, 48.

If the two side parts 6, 6a, 6b are now folded outwards again, the result is that connections between the fuselage front wall 35 and side part front wall parts 33, 37 fixed via the front wall adhesive tabs 53, 54 and connections between the fuselage floor panel 25 and side panel floor panels fixed via the floor adhesive tabs 51, 52 23, 27 have arisen, the blank 9 to form a semi-finished bumper packaging 1. In this case, the openings between the front wall 30 and the rear wall 10 must first be closed. This is done by superimposing the front / rear wall connection field 31, 39 over the rear wall / front wall connection field 11, 19 and closing it by means of a side part double fastener 73, 75.

Fig. 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 cover fields 42, 43, 45, 47, 48 are open. In this Fig. 4 the rear wall 10 is also visible. In this state of the packaging, the goods to be packaged, in particular a bumper, can be brought into the packaging.

To close the cover 4, 40, all cover panels 42, 42, 45, 47, 48 and the front wall tabs 67, 68 are folded inward until they form an angle of 90 ° or approximately 90 ° with the front wall 30 or the rear wall 10 . The lid 4, 40 is then secured to the base 3 by inserting the lid tabs 61, 62 into the base 3, the lid locking tabs 65, 66 being inserted into the front wall locking slots 76, 77 and another lock by interlocking the lid locking tab 71 and the fuselage front wall panel 35 is formed.

In the case of the latter closure, the punched handle 91 forms part of a cover closure, namely on the body cover field 45 via a cover closure flap fold line 700 a lid closure tab 71 is articulated, which has a lid handle punching 91 and a handle tab 92, the lid handle punching 91 and handle tab 92 with a fuselage front wall handle punching 93 form a lid lock 71, 91, 92, 93. The grip tab 92 is formed in that the handle punching 91 is not completely punched out, but rather remains connected in an area on the cover 40 and can be pivoted about a grip tab fold line 900. The handle flap fold line 900 is arranged on the side facing the lid closure flap 71. If the cover 4 is closed, the cover handle punching 91 and the fuselage front wall handle punching 93 come into congruence. The grip tab 92 can be pressed inwards and thus secures the lid 4 to the packaging 1.

You get the in Fig. 1 Sealed bumper packaging shown 1.
