Description

Plastic container

The present invention relates to a plastic container according to the preamble of the independent claims.

A large number of plastic containers are known from the prior art.

Various methods are known for the production of plastic containers, in particular plastic bottles, the application of which depends not least on the plastics used. The plastic containers are usually produced in a blow molding process, in which plastic containers, for example plastic bottles, are blown into their final shape by overpressure in a blow mold. In blow molding, a distinction is made between different process technologies, of which the extrusion blow molding process, the injection blow molding process and the injection stretch blow molding process should be mentioned in particular. In the extrusion blow molding process, a single or multilayer plastic tube is hot extruded, introduced into a blow mold and blown into a plastic container via a blow pin inserted into a mold cavity of the blow mold. The injection blow molding process is a combination of injection molding and blow molding. First, a preform is produced in an injection molding process in an injection mold. The preform is removed from the injection mold, conditioned if necessary, and introduced into the mold cavity of a blow mold, in which it is finally inflated with excess pressure in accordance with the shape given by the mold cavity. Here, only the area of the preform below the neck is inflated; the neck typically already has its final shape after the injection molding. In the injection stretch blow molding process, the preform introduced into the mold cavity is additionally stretched with a stretching mandrel during the blow molding process. The preform can be inflated immediately after its manufacture using the injection molding process. In alternative manufacturing methods, the further processing of the preforms can also take place spatially and / or temporally separated from the manufacture of the preform. Finally, it should also be mentioned that the preforms can also be produced in an extrusion process or also in an extrusion blow molding process.

In addition, plastic containers have become known which have an integral handle, and it has been found that essentially only plastic containers have prevailed among users who have a handle that is separate from the rest of the container and that is fully grasped by hand can. A relatively simple solution for providing such handles is achieved in that the plastic container has a reach-through opening which penetrates a container body.

WO 2017/211540 A1 has disclosed a plastic container, in particular made of PET, which has a reach-through opening and a corresponding handle. The reach-through opening of the plastic container of WO 2017/211540 A1 is obtained by welding two wall parts to one another after the plastic container has been stretch-blow molded and then separating a corresponding area from the container, separated from the container by the weld seam.

A comparable plastic container made of polypropylene is known from EP 1835 461 A2.

Both plastic containers have a connecting seam located in the reach-through opening. Under certain circumstances, this can form a weak point on the plastic container, which can be disadvantageous, especially in mail-order business, where the handling of the products cannot be fully controlled and these are repeatedly exposed to their permissible mass. Since this connection seam is produced on the finished blown plastic container, it must be pleasant to the touch and be carefully rounded, especially to reduce the risk of injury to the user, which necessitates additional processing steps.

It is therefore the object of the invention to eliminate at least one or more disadvantages of the prior art. In particular, a plastic container is to be provided which is stable, preferably has an attractive appearance and, in particular, has a pleasant feel and / or has a reduced risk of injury.

This object is achieved by the plastic container defined in the independent patent claim. Further embodiments emerge from the dependent claims

A plastic container according to the invention has a container body which forms a filling volume and a reach-through opening which penetrates the container body. The reach-through opening forms a handle with a partial area of the container body.

A handle insert is arranged in the reach-through opening. A section of the handle insert is thus also part of the handle.

The handle insert, which is arranged in the reach-through opening, in particular completely within the reach-through opening, makes it possible to provide a contour / inner contour for the handle that is independent of the contour and / or size, that is to say the specific design of the reach-through opening. In this case, it is possible in particular to provide molds or structures which cannot easily be produced in a blow molding process.

The provision of a handle insert in the reach-through opening also enables a connecting seam, for example a weld seam, that extends at most within the reach-through opening along a circumference of the reach-through opening. can be covered with the handle insert so that it is no longer accessible to a user touch.

The handle insert therefore runs around completely to cover the connecting seam along the inner contour or the circumference of the reach-through opening.

In the area of the reach-through opening, the container body has two cross-sections which are separate from one another, but which are connected to one another above and below the reach-through opening and thus form a common filling volume. The cross section of the partial area that forms the handle is typically many times smaller than the wider cross section.

It can be provided that the handle insert has a parting plane.

This enables the handle insert to be inserted into the reach-through opening even if the handle insert is designed in the area of its outwardly directed ends or surfaces that are larger than the clear cross-section of the reach-through opening, so that with the handle insert a sub-area of the handle insert extends along the periphery the through-opening extending container body can be covered.

It is conceivable that the parting plane is arranged essentially in the direction of the reach-through opening, so that the grip insert can be inserted essentially in a spiral shape into the reach-through opening.

A two-part design of the handle insert with a parting plane in the direction of the reach-through opening is also conceivable. This makes it possible to insert a first half of the handle insert into the reach-through opening and to move it essentially along the mold parting plane of the plastic container and to move a second half of the handle insert essentially equally to be inserted into the reach-through opening and to be moved in the opposite direction.

The handle insert is preferably designed in two parts and has a first shell and a second shell.

This makes it possible to insert the handle insert into the reach-through opening in sections from several sides.

The parting plane of the handle insert can be formed essentially parallel to a mold parting plane of the plastic container.

The formation of the parting plane essentially parallel to the mold parting plane of the plastic container enables the handle insert, divided into two halves, which in the present case correspond to a first shell and a second shell of the handle insert, to be introduced into the reach-through opening from two sides. This allows simple and, in particular, mechanical assembly of the respective handle insert in the plastic container.

It can be provided that the first shell has a first contact surface and the second shell has a second contact surface, which are directed towards one another. In other words, surfaces that are essentially complementary to one another are provided on the first shell and on the second shell and can be brought into contact and / or operative connection with one another.

On the one hand, this makes it possible to maintain a specific distance between outer surfaces of the handle insert, on the other hand, corresponding connecting means can be provided and / or attached to these surfaces, which make it possible to connect the first shell to the second shell. The first contact surface and the second contact surface can be connected to one another, in particular glued to one another or welded to one another.

Correspondingly, an adhesive is provided as the connecting means, in which case this can simply be applied to the corresponding contact surfaces and connects them to one another as soon as they are pressed onto one another.

Welding also enables a secure and permanent connection between the first shell and the second shell via the contact surfaces. However, welding is not equally suitable for all plastics, so that with different plastics, more or less preparatory measures have to be taken for welding.

However, it can also be provided that the connection between the first shell and the second shell is additionally or alternatively designed mechanically. It can be provided that the first shell and the second shell are connected to one another via a snap connection.

A snap connection is characterized in that a first element is connected to a second element, one of the elements being at least partially elastically deformed and this deformation being completely deformed back after the connection has been established. It is also possible to only partially deform it back, so that the connection is under a certain tension even in its final state.

An opening or an undercut can be formed on the first element, for example on the first shell, and an elastically deformable projection that can engage in the corresponding undercut or in the corresponding opening on the second element, that is, on the second shell. It would also be conceivable that a screw connection is provided as the connecting means in the case of a handle insert which is rotationally symmetrical about an axis.

The plastic container can have a circumferential projection within the reach-through opening. The grip insert can have a first pressing element and a second pressing element, the first pressing element and the second pressing element resting on the projection under prestress.

It goes without saying that the preload is applied in the fully assembled state, that is, when the first shell and the second shell are connected to one another.

This makes it possible to compress the plastic container in the area of the reach-through opening, in this case the projection, and to reduce a load occurring within the projection and / or to divert it onto the handle insert. Overall, this results in a strengthening of this area. Provision can be made for a circumferential connecting seam to be arranged within the reach-through opening.

The arrangement of the connecting seam within the reach-through opening makes it possible to cover and / or shield this connecting seam with the handle insert.

The connecting seam can be formed as part of the projection. Because it is designed as part of the projection, this connecting seam is accessible before the grip area is inserted and can be arranged at a certain distance from the rest of the container body. In other words, the connecting seam is spaced from the container body in the direction of the center of the reach-through opening via the projection to the container body.

Another aspect of the invention relates to a plastic container. This has a container body which forms a filling volume and a reach-through opening which penetrates the container body on. The reach-through opening forms a handle with part of the container body. A handle insert can be arranged in the reach-through opening. In this case, a partial section of the handle insert is thus also part of the handle. The plastic container is designed in particular as described here.

The plastic container can have relief notches in the reach-through opening. The relief notches enable the energy of a shock wave, which is transferred from the liquid to the plastic container when a plastic container filled with liquid hits, is reduced.

The relief notches are designed as a recess in the plastic container.

The relief notches can be formed as part of the protrusion. In this case, viewed from a center of the reach-through opening in the direction of the plastic container or in the direction of the partial area of the plastic container that belongs to the handle, they can form an undercut opposite the projection. The free cross-section in this direction is therefore constricted. In the projection there is therefore a widening or bulge compared to the relief notch.

The undercuts form peaks in the interior of the plastic container. These tips are flexible, which means that they give in a little when a shock wave hits and thus absorb part of the energy of the shock wave.

In addition, the space in the area of the projection widens compared to the narrowest cross section. This expansion or bulge leads to turbulence in the liquid, which further reduces the energy of the shock wave. It can be provided that the handle insert has protruding elements which at least partially engage in these relief notches.

On the one hand, this increases the stability; on the other hand, the position of the handle insert in relation to the plastic container can be improved or maintained more precisely.

The relief notches are preferably covered by the handle insert. This improves the feel and appearance of the plastic container.

In a design of the plastic container as described here, in which the handle insert with its first pressure element and its second pressure element puts the projection under pretension, the connection seam can be relieved accordingly. Forces that occur, for example, in the event of vibrations or improper handling of the plastic container can thus be at least partially absorbed by the handle insert and the resulting forces acting on the connecting seam are significantly reduced.

The first pressing element and / or the second pressing element can be constructed in several parts. The respective pressing element can for example be formed from a plurality of individual ribs.

On the one hand, this enables material to be saved, and on the other hand, the prestress can be introduced into the projection at specific points.

The grip insert preferably has reinforcing ribs, in particular arranged between the respective pressing element and an associated surface. This is in each case the outwardly directed surface of the handle insert that provides a surface of the handle. A design with reinforcing ribs is particularly advantageous if the surface of the handle insert is at a large distance from the container body and / or if a high degree of overlap is desired between the handle insert and the container body.

The plastic container can be a stretch-blown plastic container, in particular made of PET, PET-G, EBM-PET, HDPE, LDPE, PP, PS, PVC, PEN, PHA, PHB, PEIT, PCTG, LLDPE, MDPE and copolymers of the listed Plastics, bioplastics, in particular PLA or PEF, filled plastics and mixtures of the plastics mentioned.

The handle insert can be an injection-molded part, in particular made of PET, PET-G, HDPE, LDPE, PP, PS, PVC, PEN, PHA, PHB, PEIT, PCTG, LLDPE, MDPE and copolymers of the plastics mentioned, bioplastics, in particular PLA or PEF , filled plastics and mixtures of the plastics mentioned.

The plastic container and the handle insert are preferably made of the same material.

A laborious separation process can be dispensed with when it is recycled.

As already discussed, the handle insert is arranged in the reach-through opening. This means that the handle insert, for example, does not completely encompass any elements or partial areas of the plastic container. The handle insert is preferably arranged completely within an enveloping outer contour of the plastic container. In other words, the surfaces of the handle insert do not protrude beyond the enveloping outer contour of the plastic container.

With the aid of figures, which are only shown schematically, the invention is explained in more detail with the aid of exemplary embodiments. It shows: Figure 1: a plastic container;

FIG. 1 shows a plastic container 1 which has a container body 10. The container body 10 provides an unspecified filling volume. The container body 10 is penetrated by a reach-through opening 11 and is thus in two parts in the area of the reach-through opening 11. The container body 10 thus has two different cross-sections in this area. A handle insert 13 is arranged within the reach-through opening 11. The handle insert 13 forms, with a partial area 10a of the container body 10, a handle 12 for holding and manipulating the plastic container 1.

FIG. 2 shows a sectional view of FIG. 1 along the line AA. Inside the reach-through opening 11 is a Handle insert 13 arranged. In the present case, the handle insert 13 has a first shell 13a and a second shell 13b, which are connected to one another along a parting plane 14. The parting plane 14 lies essentially in a mold parting plane, which is not designated in any more detail, of the plastic container 1 (see FIG. 1). The handle insert 13 forms, together with a partial area 10 a of the container body 10, a handle 12. The handle insert 13 has a first outwardly directed surface 135 and a second outwardly directed surface 136. In the present case, outwardly directed means that the respective outer surface or surface faces an outer contour of the plastic container 1. Nevertheless, the handle insert 13 is arranged completely within the enveloping outer contour of the plastic container 1. In other words, the surfaces 135 and 136 of the handle insert do not protrude beyond the enveloping outer contour of the plastic container 1. In the area of the reach-through opening 11, the enveloping outer contour is the contour that the plastic container 1 would have if no reach-through opening 11 were arranged, i.e. essentially a continuous connection of the surfaces of the container body 10 that border the reach-through opening. The first shell 13a has a first pressure element 133 and the second shell 13b has a second pressing element 134. In the area of the reach-through opening 11, the container body 10 has a circumferential projection 16 on which a connecting seam 17 is arranged. In the present embodiment, the circumferential projection 16 has two outwardly directed bulges or bulges. These are connected to the plastic container via a relief notch 161. In the area of the relief notch 161, the cross section thus has a constriction and in the area of the projection 16 an enlargement. The first pressing element 133 and the second pressing element 134 are in operative connection with the projection 16 and in the present case with the respective curvatures. The first shell 13a and the second shell 13b overlie first and second contact surfaces 131, 132 (see FIG Figure 3) on each other. Correspondingly, there is a specific distance between the first pressing element 133 and the second pressing element 134 which is less than a minimum width of the circumferential projection 16 at the respective corresponding point. The circumferential projection 16 is thus pressed together by the first pressing element 133 and the second pressing element 134 and placed under prestress. Forces that now occur in this area are thus absorbed via the handle insert 13. The connecting seam 17 lying within a contour of the handle insert 13 is thus relieved.

FIG. 3 shows an exploded view of the handle insert 13 from FIG. 2 in a three-dimensional view. The handle insert 13 comprises a first shell 13a and a second shell 13b. The first shell 13a has a first contact surface 131. Arranged along the periphery of the first contact surface 131 is a first pressure element 133 which in the present case is formed from individual ribs. The second shell 13b likewise has a second contact surface 132. A second pressing element 134 is likewise arranged along the periphery of the second contact surface 132. The second pressing element 134 is also formed from individual ribs. In normal use, the first contact surface 131 faces the second contact surface 132.

In the present case, the first contact surface 131 and the second contact surface 132 are essentially planar. To connect the first shell 13a to the second shell 13b, in this embodiment an adhesive is applied to the first and / or second contact surface 131, 132 and the first shell 13a and the second shell 13b are pressed onto one another with their contact surfaces 131, 132 .

FIG. 4 shows a sectional view corresponding to the view in FIG. 2 through a plastic container 1. The plastic container 1 corresponds to that of FIG A handle insert 13 'is arranged through the reach-through opening 11. The handle insert 13 ′ is also arranged completely within the outer contour of the plastic container 1. The handle insert 13 'in the present case has a first shell 13a' and a second shell 13b ', which are connected to one another along a parting plane 14'. The parting plane 14 ′ lies essentially in a mold parting plane, not designated in any more detail, of the plastic container 1. The handle insert 13 ′, together with a partial area 10a ′ of the container body 10, forms a handle 12 ′. The handle insert 13 'has a first outwardly facing surface 135' and a second outwardly facing surface 136 '. In the present case, outwardly directed means that the respective outer surface or surface faces an outer contour of the plastic container 1. The first shell 13a 'has a first pressing element 133' and the second shell 13b 'has a second pressing element 134'. The container body 10 has in the area of the reach-through opening 11 a circumferential projection 16 on which a connecting seam 17 'is arranged. In the present embodiment, the circumferential projection 16 'has two outwardly directed bulges or bulges. These are connected to the plastic container via a relief notch 161 '. The cross section thus has a constriction in the area of the relief notch 161 'and an expansion in the area of the projection 16'. The first pressing element 133 'and the second pressing element 134' are in operative connection with the projection 16 'and in the present case with the respective curvatures. The first shell 13a 'and the second shell 13b' rest on one another via first and second contact surfaces 131 ', 132' (see FIG. 5). Correspondingly, there is a specific distance between the first pressing element 133 'and the second pressing element 134' which is less than a minimum width of the circumferential projection 16 '. The circumferential projection 16 'is thus pressed together by the first pressing element 133' and the second pressing element 134 'and placed under pretension. Forces now in this area occur are thus recorded via the handle insert 13 '.

The connecting seam 17 'lying within a contour of the handle insert 13' is thus relieved.

FIG. 5 shows an exploded view of the handle insert 13 'of FIG. 4 in a three-dimensional view. The handle insert 13 'comprises a first shell 13a' and a second shell 13b '. The first shell 13a 'has a first contact surface 131'. Arranged along the periphery of the first contact surface 131 'is a first pressing element 133' which in the present case is designed as a circumferential shoulder. The second shell 13b 'likewise has a second contact surface 132'. A second pressing element 134 'is likewise arranged along the periphery of the second contact surface 132'. The second pressing element 134 'is also designed as a circumferential projection. When used properly, the first contact surface 131 'faces the second contact surface 132'.

In the present case, the first contact surface 131 'and the second contact surface 132' are essentially planar. To connect the first shell 13a 'to the second shell 13b', four snap connections 15a ', 15b' are provided in this embodiment, whereby for the sake of clarity only one of the snap connections 15a ', 15b' is designated and in the present case in more detail is explained. The snap connection 15a ', 15b' has a first element 15a 'and a second element 15b', the first element 15a 'being designed as an opening with an undercut and the second element 15b' as an elastically deformable projection. When they are joined together, the elements 15a 'and 15b' engage one another so that a connection is created between the first shell 13a 'and the second shell 13b'.

The grip insert 13 'according to FIG. 5 is provided with reinforcing ribs 137' which are each between the first pressing element 133 'and the associated surface 135' or between the second pressing element 134 'and the associated surface 136' are arranged.

FIG. 6 shows an alternative embodiment of the handle insert 13 'of FIGS. 4 and 5. FIG. 6 shows a sectional view corresponding to the view in FIG. 2 through a plastic container 1 ". A handle insert 13 "is arranged within the reach-through opening 11". The handle insert 13 ″ is also arranged completely within the outer contour of the plastic container 1 ″. The handle insert 13 ″ in the present case has a first shell 13a ″ and a second shell 13b ″, which are connected to one another along a parting plane 14 ″. The parting plane 14 ″ lies essentially in a mold parting plane, which is not designated in any more detail, of the plastic container 1 ″. The handle insert 13 ″ together with a partial area 10a ″ of the container body 10 ″ forms a handle 12 ″. The handle insert 13 ″ has a first outwardly directed surface 135 ″ and a second outwardly directed surface 136 ″. In the present case, outwardly directed means that the respective outer surface or surface faces an outer contour of the plastic container 1 ″. The first shell 13a ″ has a first pressure element 133 ″ and the second shell 13b ″ has a second pressure element 134 ″. The container body 10 ″ has a circumferential connecting seam 17 ″ in the area of the reach-through opening 11 ″, which protrudes from the container body 10 ″ and thus provides an element corresponding to the projection 17 ′ of the exemplary embodiment according to FIG. In the present embodiment, the circumferential connecting seam 17 ″ has two essentially planar sections of the walls of the plastic container 10 ″. These flat sections are connected to the plastic container via relief notches, which are not designated in any more detail. The first pressing element 133 ″ and the second pressing element 134 ″ are in operative connection with these walls and thus with the connecting seam 17 ″. The first pressing element 133 ″ and the second pressing element 134 ″ press the walls of the Connection seam 17 ″ against one another, so that the connection seam 17 ″ is under pretension.

Forces that now occur in this area are thus absorbed via the handle insert 13 ″. The connecting seam 17 ″ lying within a contour of the handle insert 13 ″ is thus relieved.

FIG. 7 shows an exploded view of the handle insert 13 ″ from FIG. 6 in a three-dimensional view. The handle insert 13 ″ comprises a first shell 13a ″ and a second shell 13b ″. The first shell 13a ″ has a first pressure element 133 ″ which in the present case is designed as a circumferential surface. The second shell 13b 'also has a second pressing element 134'. The second pressing element 134 'is also designed as a circumferential surface. When used properly, the first pressing element 133 ″ faces the second pressing element 134 ″.

To connect the first shell 13a ″ to the second shell 13b ″, five snap connections 15a ″, 15b ″ are provided in this embodiment, with only one of the snap connections 15a ″, 15b ″ being designated for the sake of clarity is explained in more detail here. The snap connection 15a ", 15b" has a first element 15a "and a second element 15b", the first element 15a "being designed as an opening with an undercut and the second element 15b" being an elastically deformable one Head Start. When they are assembled, the elements 15a ″ and 15b ″ engage one another, so that a connection is created between the first shell 13a ″ and the second shell 13b ″. The first pressing element 133 ″ and the second pressing element 134 ″ then press the walls of the connecting seam 17 ″ against one another, so that the connecting seam 17 ″ is pretensioned (see FIG. 6 in this regard). The handle insert 13 ″ according to FIG. 7 is provided with reinforcing ribs 137 ″, which are each between the first pressure element 133 ″ and the associated surface 135 ″ or between the second pressure element 134 ″ and the associated surface Surface 136 ″ are arranged. In order to set a specific spacing of the pressing elements 134 ″ and 133 ″ from one another, projections 138 ″ can be provided on one of the pressing elements 133 ″ and 134 ″. In the present case, these are designed as knobs which are arranged on an elastic projection.

FIG. 8 shows a further embodiment of a handle insert. FIG. 8 shows a sectional view corresponding to the view in FIG. 2 through a plastic container 1 ″. This plastic container 1 ″ corresponds to the plastic container described for FIG. A handle insert 13 "" is arranged within the reach-through opening 11 ". The handle insert 13 ″ ″ is also arranged completely within the outer contour of the plastic container 1 ″. The handle insert 13 ″ ″ in the present case has a first shell 13a ″ ″ and a second shell 13b ″ ″, which are connected to one another along a parting plane 14 ″ ″. The parting plane 14 ″ ″ lies essentially in a mold parting plane (not shown in more detail) of the plastic container 1 ″. The grip insert 13 ″ ″ together with a partial area 10a ″ ″ of the container body 10 ″ ″ forms a handle 12 ″ ″. The handle insert 13 '''has a first outwardly directed surface 135''' and a second outwardly directed surface 136 '''. In the present case, outwardly directed means that the respective outer surface or surface faces an outer contour of the plastic container 1 ″. The first shell 13a '''has a first pressing element 133''' and the second shell 13b '''has a second pressing element 134'''. The container body 10 ″ has a circumferential connecting seam 17 ″ in the area of the reach-through opening 11 ″, which protrudes from the container body 10 ″ and thus provides an element corresponding to the projection 17 of the exemplary embodiment according to FIG. the In the present embodiment, the circumferential connecting seam 17 ″ has two essentially planar sections of the walls of the plastic container 10 ″. These flat sections are connected to the plastic container via relief notches, which are not designated in any more detail. The first pressing element 133 '''and the second pressing element 134''' are in operative connection with these walls and thus with the connecting seam 17 ''. The first pressing element 133 ″ and the second pressing element 134 ″ press the walls of the connecting seam 17 ″ against one another, so that the connecting seam 17 ″ is pretensioned. At the same time, the first shell 13a '''and the second shell 13b''' rest on one another via first and second contact surfaces 131 ''',132''' (see also FIG. 9).

Forces that now occur in this area are thus absorbed via the handle insert 13 ″. The connecting seam 17 ″ lying within a contour of the handle insert 13 ″ ″ is thus relieved.

FIG. 9 shows an exploded view of the handle insert 13 '''of FIG. 8 in a three-dimensional view. The grip insert 13 "" comprises a first shell 13a "" and a second shell 13b "". The first shell 13a '''has a first contact surface 131'''. Arranged along the periphery of the first contact surface 131 '''is a first pressing element 133''' which in the present case is designed as a circumferential shoulder. The second shell 13b '''likewise has a second contact surface 132'''. A second pressing element 134 '''is also arranged along the periphery of the second contact surface 132'''. The second pressing element 134 '''is also designed as a circumferential shoulder. In normal use, the first contact surface 131 '''faces the second contact surface 132'''. The first contact surface 131 '''and the second contact surface 132''' are embodied in the present case essentially planar. To connect the first shell 13a ″ ″ to the second shell 13b ″ ″, six plug connections are provided in this embodiment. Each plug connection has a projection 19 and an opening 18. For the sake of clarity, only the elements of one of the plug connections are designated and are explained in more detail here. To connect the shell 13a ″ ″ to the shell 13 ″ ″, these are moved towards one another and the projections 19 are introduced into the openings 18. The projections have external ribs so that an outer contour of the projections 19 is larger than an inner contour of the openings 18. This enables the projections 19 to be clamped in the openings 18. The shells 13a '''and13b''' can thus be securely connected.

The number of connecting elements, for example the number of plug connections or also the number of snap connections, which are described here, are not to be understood as limiting. However, at least three connecting elements are preferably provided.
