Transport packaging for objects with a hollow space open to the outside with a sensitive surface,

especially for sanitary elements

The innovation concerns a transport packaging for objects with a hollow space open to the outside and with a sensitive surface, in particular for sanitary elements, with

(a) an outer carton;
15

b) a folding insert arranged in the outer carton and constructed from a cardboard blank, which has at least one receptacle for an object.

In the sanitary sector, only pre-assembled sanitary fittings are often delivered from the factory in so-called "assembly sets", which are then assembled on site by the sanitary fitter to form the finished fitting. This is especially true for concealed fittings, which are delivered in two packaging units. The first packaging unit contains all the components that are required for the so-called rough assembly. A second packaging unit then contains the so-called "finished assembly set", which contains all the sanitary elements that are still required after the construction work has been completed, in particular after the tiling has been completed, for the sanitary fitting to be ready for use. These generally include visible elements that have a sensitive surface, e.g. cover and slide rosettes or

the handle of the sanitary fitting.

In the past, various attempts have been made to make the packaging of such sensitive items environmentally friendly, i.e. to use pure materials, if possible, without plastic. For example, DE-GM 92 05 066 describes transport packaging for a complete sanitary fitting, in which a bag made of textile material designed as a cleaning glove is provided inside the outer box. This protects the sensitive surface of the fitting during transport.

DE-GM 93 11 445 shows a transport packaging for a number of sanitary elements, in which a folding insert containing the actual holders for the objects is provided within an outer box. The folding insert is created by placing a cardboard cut-out and a protective cloth on top of each other, which are then folded together and thus set up for use.

The aim of this innovation is to design transport packaging of the type mentioned above in such a way that it can be produced even more cheaply and yet still reliably protects the sensitive surfaces.

This task is solved according to the present innovation by

d) the first tab of the first panel has, on its edge opposite the bending line, a slot extending towards the bending line but not reaching it;

e) the second panel has at least one slot extending partially inside and partially outside the second tab;

f) the first tab through the slot of the second field

and is connected to the second tab in such a way that an unslotted area of the other tab is accommodated in the slots of one tab.

According to the present innovation, the interlocking tabs of the fields of the folding insert lying on top of one another form a so-called "tab cross" which - self-stabilizing - has its extension direction perpendicular to the fields lying on top of one another. The contours of these tab crosses are designed to complement the corresponding cross-sectional profiles of the cavities that the objects to be held have. These objects with their cavities can thus simply be slipped over the tab crosses, where they provide a reliable

Find a hold, but at the same time be kept at a distance from all objects whose contact could endanger the highly sensitive surface. The innovation uses only one material, e.g. cardboard, so that the transport packaging is extremely environmentally friendly.

It is most practical if the angle formed by the bending line of the first tab with the bending line of the second tab is 90°. Then the tab cross formed by the two tabs is particularly mechanically stable.

The production of the folding insert is particularly cost-effective if the second field is made in one piece with the first field of the folding insert and is folded over the first field along a bending line.

An example of the innovation is explained in more detail below using the drawing;

Figure 1 shows a blank 1 made of cardboard, from which a folding insert for transport packaging is constructed. The blank 1 comprises four

4038.0 «.&dgr; .-S. ·„· : ..· ; 25.03.1994

rectangular fields 2, 3, 4, 5. Fields 2, 3, 4 are next to each other; fields 2, 3 are connected by a first bending line 6 and fields 3 and 4 by a second bending line 7. The fourth field 5 abuts the front of the middle field 3 and is connected to it by a third bending line 8.

In the side panels 2, 4 of the blank 1, two further bending lines 9, 10 and 11, 12 are also provided at the same distance from each other and from the edges of these panels, which run parallel to the bending lines 6 and 7 separating the panels 2, 3, 4 from each other.

In the side panels 2 and 4, various cutting lines 13, 14, 15, 16 are also shown, which together with the corresponding bending lines 17, 18, 19, 20 form holders for certain objects in the folding insert to be constructed. However, these holders are in and of themselves conventionally designed and are of no further interest in the present context.

In the middle field 3 of the blank 1, a first tab 23 that can be bent out of the plane of the field 3 is formed by a cutting line 21 and a bending line 22. The cutting line 21 is guided in such a way that a central slot 24 is created in the edge of the tab 23 opposite the bending line 22, the direction of which is perpendicular to the direction of the bending line 22.

By means of a further cutting line 25 and a further bending line 26 running parallel to the bending line 22, a further tab 27 is formed next to the tab 23 in field 3 of the blank 1, which is also provided on its edge opposite the bending line 26 with a slot 28 extending perpendicularly to the bending line 26.

is.

The two tabs 23 and 27 differ essentially only in the dimensions and the detailed geometry of the cutting lines 21 and 25, respectively, which are adapted to the objects to be picked up.

In field 5 of blank 1, a third tab 31 is defined by a cutting line 29 and a bending line 30. The bending line 30 is perpendicular to the bending line 22 of the first tab 23.

A slot 32 extends parallel to the bending line 22 of the first tabs 23 in field 5, partly outside the area that forms the tab 31 and partly within this area. The distance of this slot 32 from the bending line 8 between fields 1 and 5' corresponds to the distance of the bending line 22 of the first tab 23 from the bending line 8 between fields 3 and 5. The length of the area of the slot 32 that lies inside the tab 31 corresponds to the distance that the inner end of the slot 24 of the first tab 23 has from the bending line 22. The length of the area of the slot 32 that lies outside the tab 31 corresponds to the distance between the left end of the bending line 22 in Figure 1 and the intersection point of the bending line 22 with a straight line that extends the slot 24 in the direction of the bending line 22.

In a corresponding manner, a fourth tab 35 is formed in the fourth field 5 of the blank 1 by a cutting line 33 and a bending line 34. The bending line 34 of the fourth tab 35 is perpendicular to the bending line 26 of the second tab 27. A slot 36 in field 5 of the blank runs parallel to the bending line

4038.0 «»7 ·&iacgr;. '..* : ..· &Ggr; 25.03.1994

26 of the second tab 27 and has the same distance from the bending line 8 between the fields 3 and 5 as the bending line 26. The slot 36 has a length outside the area of the tab 35 which corresponds to the distance between the left end point of the bending line 26 in Figure 1 and the intersection point of the bending line 26 with a straight line which extends the slot 28 of the second tab 27 in the direction of the bending line 26. The length of the area of the slot 36 which lies within the tab 35 corresponds to the distance between the inner end of the slot 28 of the second tab 27 from the bending line 26.

A folding insert is now produced from the blank 1 shown in Figure 1, as shown in an intermediate step in Figure 2:

The side panels 2 and 4 of the blank 1 are formed by appropriate bending around the bending lines 6, 9 and 10 or 7, 11 and 12 into two lateral elevations 37, 38, which extend on both sides of the middle panel 3. In these elevations 37 and 38, the various receptacles for specific objects, which are not of any further interest here, are also produced by appropriate bending out.

From the middle field 3 of the blank 1, the tabs 23 and 27 are bent upwards along the bending lines 22 and 26 into the vertical position shown in Figure 2. In a corresponding manner, the tabs 31 and 35 from field 5 are bent downwards along the bending lines 34 and 35 into the vertical position shown in Figure 2.

5 Then field 5 is filled with the

Arrow 39 indicated, folded upwards along the bending line 8 and then inwards over the field 3 between the elevations 37 and 38. The tab 23 passes through the area of the slot 32 lying within the area of the field 5 as well as the recess 40 which is created after the tab 31 is bent out in the field 5 of the blank 1. The area of the slot 32 lying within the tab 31 slides over the field 3 when the field 5 is folded over onto the area of the first tab 23 which lies between the lower end of the slot 24 of the first tab 23 and its bending line 22. The slot 24 of the first tab 23, on the other hand, takes up the area of the tab 31 which lies above its slot 32. As a result, a self-stabilizing cross of tabs is created in the finished folded folding insert 1, as shown in Figure 3 already within an outer box 41.

The same thing happens with the tabs 27 and 35 when the fields 5 and 3 of the blank 1 are folded over one another: The tab 27 partially penetrates the slot 36 and partially the recess 42, which remains in the field 5 after the tab 35 is bent out. The area of the slot 36 lying inside the tab 35 slides over the area of the tab 27 that lies between the inner end of the slot 28 and the bending line 26. The slot 28 of the tab 27 in turn takes up the area of the tab 35 that lies above the erected folding insert, as shown in Figure 3. This creates a second tab cross that stabilizes itself, but whose size and geometry differ from the size and geometry of the first tab cross.

In Figure 3, various parts 43 to 48 are shown - not yet inserted into the folding insert 1 - which

4038.0 rf.S .t. ·..· : ..· ; 25.03.1994

together form the decorative extension kit (ready-to-assemble kit) of a concealed sanitary fitting. The exact nature of these parts 43 to 48 is not of interest in the present context. It is sufficient to know that parts 45 (a decorative rosette) and 44 (a handle) have a sensitive outer surface that must be protected from damage during transport. Both parts 45 and 44 also have an inner cavity accessible from the outside (not visible in the drawing), which is insensitive and with which these parts can be pushed over the tab crosses, as shown in Figure 4.

The other parts, 43, 46, 47, 48, are accommodated in the various receptacles in the two lateral elevations 37 and 38 of the folding insert.
