"Packaging"

The invention relates to packaging according to the preamble of claim 1. Such packaging is known from DE-GM 81 11 238. This is on the hold of two Packaging parts related, in the form of a lower part and the upper part hold the goods to be packaged between them. However, this only covers a small area of the packaging requirement covered. Although a packaging made of several parts made of plastic foam is known, the lie in one plane when not in use and for bringing about the packaging position out of this plane into the packaging layer via hinge-like connections be folded, in the z. B. a side part to the bottom part assumes an angle of 90 °. Here are the hinge-like connections through what has stopped, that is

Material that has not been cut or punched away e! * s Plastic foam formed in the form of thin webs. It has it has been shown that these thin webs cannot withstand the mechanical stresses that are placed on them Act on the packaging. These are not just the mechanical forces, such as weight, shock, etc., exerted by the packaged Well created, or from the outside on this and the packaging act. Such prepackages can also be damaged before or during the packaging process. In extreme cases, these mechanical effects can lead to a complete separation of one or more of the side walls from the floor and thus render the packaging unusable. This is particularly serious with Goods that have already been packaged, as this leaves them open and can be damaged.

In contrast, the object of the invention is to a package according to the first part of claim 1 in such a way that they, without having to accept the disadvantages of the latter type of packaging, a packaging with a larger number of parts made of plastic foam is, on the one hand, simple and is inexpensive to manufacture and, on the other hand, enables the operating personnel to handle it without problems.

Serve to solve this problem, starting from the generic term of claim 1, the features of the characterizing part of claim 1. By the interaction of the features of Claim 1 is a package created through which the object to be packaged on all sides, at least to the desired sides of made of plastic foam Parts (floor, walls and possibly also cover) is covered and protected against damage. It is through

the connections provide the necessary firm mechanical hold secured between the plastic foam parts. One is not necessarily on the miter cuts of the previously known Packaging instructed that a corresponding manufacturing effort demand. In particular, one has to do with the Manufacture of the arts ts to F f schauml ^ i Ir? and their attachment do not pay attention to the connections that the Plastic foam parts over the ο, r ,. Stn ^ e with each other are connected. Rather, the invention can still do such Kunstatoffschäumcixe manufactured for themselves and in any desired number via the connections, however, they can be held together so that they can be folded together. So there is no material connection, e.g. H. between the plastic foam base and plastic view side walls such packaging is required.

A preferred embodiment of the invention is the subject matter of claim 2. This requires relatively little manufacturing costs. In addition, the usually smooth walls on the outside of the packaging layer are the Plastic foam parts thus cover their entire surface covered with the Pappeηbahn, plastic film or the like. On the one hand, this provides protection against damage the relatively soft plastic hem. aside from that can be such a cardboard or plastic film carrier of Advertising printing, instructions for use of the unpacker. etc. be.

Instead, there would also be a packaging according to claim 3 possible, but this does not have the special advantages of claim 2.

I ·

The features of claim 4 are a further advantageous embodiment of the end stops and the associated Links.

The features of claims 5 and 6 are for themselves be familiar, but also an advantage in the present context.

The features of claim 7 enable an object surrounded by the bottom part ur.d four side wall parts against falling out on the still open cover side to secure without providing a complete cover there and having to connect it to the Seitenwandteiien.

Claim B represents a further variant of the invention regarding the creation of the end stops.

Embodiments of the invention from which wide Details are explained below and shown in the drawing. In the drawing shows:

Fig. 1: a first embodiment

of the invention in plan view,

Fig. 2: a section along the line ΙΪ-ΙΙ in Fig. 1,

Fig. 3: a section analogous to the line H-II in Fig. 1, but in the folded Packaging lagp,

4: a section along the line IV-IV in Fig. 1, but folded,

The plastic foam parts are only used for packaging and if necessary. Thermal insulation, but no longer their connection among themselves. This function is performed by the track 7. It is preferably pre-grooved so that these grooves 8 form the hinge-like points around which the turning parts to the bottom part and possibly. also the cover parts the wall parts are foldable, as explained is a material Cohesion of the plastic foam parts 1 up to 6 'between each other not required. So you can at a distance from one another, as is also the case in this exemplary embodiment shows. Preferably, the web 7 is glued to the plastic sleeve parts over their entire surface, or connected by means of a heat seal lacquer layer

Fig. 5: a further variant of the invention

on average.

The packaging in FIGS. 1 to 4 initially consists of several plastic foam parts, namely the base 1, the four side parts 2 to 5 and the two cover parts 6, B ¹ . The aforementioned plastic foam parts are glued to a flat, ie flat sheet of plastic, plastic film, cardboard or the like, which forms the connection between the aforementioned parts, is generally denoted by 7 and in this preferred embodiment of the invention in its outline d "m outline of the Packaging as shown in Fig. 1 corresponds. The web 7 is glued with the plastic foam parts, preferably by means of a heat-sealing lacquer layer, which is applied either to the cardboard or the film or to the surface of the plastic foam parts facing the web 7 before production. The comparison is achieved by heating bond i.

The plastic foam parts, which are preferably made of an expandable Polystyrene (EPS) are not only kept safe, but also against any Damage to their outside protected.

The end stops, which secure the desired angular position of the plastic foam parts in the packaging position to one another, can be designed in various ways. These can be mitered surfaces 9, ID of the side edges of the plastic foam parts which lie against one another in the packaging layer. To avoid the manufacturing technology complicated miter cut, and the cutting of the plastic foam parts with a rectangular, in principle, cross-section is possible, wherein the two narrow sides 11, 12 of the opposed rectangular Y unststoffschaumteile unfolded are at a distance (see Fig. 1 and 2), whereas in the Packaging layer form a packaging that completely surrounds the goods to be packaged. The associated track is dimensioned accordingly. 3 shows a further variant of the formation of end stops by means of two projections 13, 14 of two parts which can be folded against one another and which also define the packaging layer.

Fig. 3 shows, moreover, that you can with the help of the cover parts 6, 6 'secure the packaged goods located in space 15 against falling out in the direction of arrow 16 can without having to provide a complete cover. If the goods to be packaged have recesses into which z. B. projections 17 iier respective side wall ^ nit the If flaps penetrate into the packaging layer, a stop would also be possible with it. This is further in the variant shown in FIG. 5, the goods to be packaged

is shown schematically with 1Θ. At the same time it can be seen from this that in such a case the to be packaged Good IB at the same time the counter-end stop to the projections 17 can form for the purpose of fixing or determining the final packaging position. Furthermore, Fig. 5 shows that the Connection also only in the form of also flat strips or sections 13 that only cover part of the The surface of the outside of the plastic creates parts ?, le I, 2, etc. cover, but also in accordance with Section Q hinge function to have.

The invention is not limited to the exemplary embodiments shown, in which the individual plastic foam parts in the packaging layer each form an angle of 90 ° with one another. Depending on the shape of the goods to be packaged, other angles can also be achieved here, e.g. B. 30 °, 60 °, etc. Instead of the cover parts 6, 5 ^1, a complete cover according to the invention can also be hinged to the other plastic foam parts.
