packaging

The innovation relates to packaging, in particular produced by molding from foamed polystyrene or corresponding materials.

Its purpose is a multi-surface packaging, which is characterized by a lower part in the form of one that is open at both longitudinal ends Trough with parallel flanks at least in the vicinity of each of the two longitudinal ends with one in at least one of its inner surfaces formed transverse groove of a certain width is provided, also a channel-shaped, at its two longitudinal ends open cover with parallel flanks, which extends parallel to the lower part with facing cavities of the two parts can fit on, the flanks of the lid at least partially overlapping those of the lower part and the flanks of Lower part and cover are provided with additional devices that hold them together, and at least two removable, forming the longitudinal walls of the packaging and each transversely extending partially into one of the grooves in the lower part End plates.

The packaging according to the innovation can have any desired cross-section have: square, rectangular, polygonal, round or rounded, as far as the lower part and cover are each parallel Have flanks that are advantageously in to the plane of symmetry of the lower part or cover run parallel planes.

The transverse grooves in the lower part of the packaging can either only be in the inner wall of the bottom of the lower part or only in the Inner surfaces of the flanks of the same or you both in the inner surfaces of bottom and flanks and in this case be continuous.

According to an advantageous measure of the innovation, at least two grooves are defined on the inner surface of the bottom of the cover Width provided, which are arranged opposite the grooves of the lower part and in which also partially the. 3.; · Penetrate the longitudinal walls of the packaging forming end plates.

The width of each groove can be substantially equal to the thickness of the end plate which it will receive or any cross-section have, which corresponds essentially to that of the engaging part of the end plate.

Depending on how they are made, cut out of panels or molded, as well as depending on the particular desired use of the In packaging, the end plates can have a constant thickness or can be designed with tapered or reinforced edges be what determines the choice of profile and dimensions of the grooves.

Advantageously, the lower part and / or the lid of the packaging are according to the innovation with a plurality of at regular intervals Transverse grooves arranged at intervals from one another, -wherein the spacing of each longitudinal end of the lower part and / or Lid's closest groove from this end essentially is equal to half the distance between two adjacent grooves from one another.

This lower part and / or this lid of the packaging according to the innovation can consist of sections of shaped elements foamed polystyrene or a corresponding material, each having the cross section of the lower part and / or the Have cover and each provided with a plurality of the same and regularly spaced transverse grooves are, the portions being deposited in the area located between two adjacent grooves.

This design allows packaging of any desired length with bases and lids of the same cross-section received, whereby the manufacturer of packaging either cuts its customers to the length of the desired packaging Can supply bases and lids or molded elements which enable the user to cut the elements himself, in order to produce bases or lids of the desired length.

In one case or another, the innovation enables a considerable amount Reduction in the cost of transporting the packaging, since the (bottoms and lids of the same or the shaped elements,

from which they are made can be packed in pairs for transport, with one flank of one each engages in the recess of the other, which reduces the space requirement to about half. This advantage arises also when storing the packaging parts that belong together or the elements from which their bases and lids are made, both with the manufacturer and with the user.

According to a feature of the innovation, the additional device for holding the packaging parts together consists of one on the outside at least one flank of the lower part is formed parallel to the upper edge of the edge and extends over its length Groove and one on the inside of at least one flank of the lid running parallel to the lower edge of the flank and Over its entire length extending projection of a substantially complementary to the shape of the groove of the flank of the lower part Shape.

According to an advantageous embodiment of the innovation, the groove has a rectangular cross section, the projection in this Case may have the shape of a rib of square or rectangular cross-section.

According to a preferred feature of the innovation, the additional device for holding the packaging parts together is arranged in such a way that that when the lid is closed, the inner surface of the bottom of the lid rests on the upper edges of the flanks of the lower part.

The lid of the packaging according to the innovation can be placed on the lower part the packaging either by sliding it lengthways

put on like a drawer or by being forced open will. In the latter case, the lid is placed on the lower part and subjected to vertical pressure, which initially the temporary and elastic deformation of the lid and in particular its flanks with respect to the flanks of the lower part and then the sliding of the parts of the holding device carried by the flanks of the cover over those on the lower part Parts of the holding device causes until the bottom of the cover strikes against the flanks (side walls) of the lower part, whereupon the release of the pressure causes the flanks (side walls) of the lid to interact with those of the lower part their respective elements of the holding device are held.

In order to slide the parts of the Holding device over the ^ u carried by the lower part of the packaging facilitate, in the event that the gripping by putting on the Cover takes place on the lower part under pressure, each groove in the flank of the lower part is preferably through its upper edge a guide surface separated, in particular on a flat Bevel or a rounded section can exist.

According to a further feature of the innovation, the package has at least three transverse panels, two of which are the longitudinal end panels form. In this way, in particular, several products can be processed separately and in each case under the most favorable conditions for them housed in the same packaging.

The transverse plates forming the end walls of the packaging and any additional transverse plates which may be present can each After the planned use of the packaging either be so high that its top edge meets the bottom of the corresponding groove of the

Lid touches, or each be so high that there is a gap between its upper edge and the lid.

In the former case one can even use the transverse plate with a small oversize with respect to the bottom to bottom of the grooves measured free heights and widths and thus create a practically hermetic connection between. the lid and lower part of the package received, whereby the package is essentially isothermal and in particular to Transporting frozen products or products prepared in a cool environment can be used, which are in the packaging by themselves keep.

In the second case, however, the interior of the packaging is ventilated, so that they can be used to transport products,

which have to be in constant contact with air. The same

If the packaging and its contents are subjected to numerous shocks and their contents are fragile, according to the new

support of the user in order to achieve [a good protection of the trans-

ported product the end plates serving as walls only at a certain distance from the longitudinal walls of the lower part and

Arrange the end of the packaging, which increases the resistance of the impact protection formed in the vicinity of the packaging end.

Transverse plates
The arrangement of two /s at a distance from one another near each end of the package can also be used when the hermetic tightness of the package is to be increased or a space is to be created to accommodate a heat-insulating or cooling material. This paired arrangement of the transverse plates is particularly advantageous if the packaging according to the innovation is used to transport fresh fish. When used in this way, a chamber for receiving ice or carbon dioxide snow is formed at each end of the package. The inner transverse plate of the plate pair has openings with a small cross-section, whereby the cooled air can enter the interior of the packaging, while the bottom of the lower part is provided with holes at least in the area which is opposite the chamber located between the transverse plates of each plate pair allows the water formed when the egg or carbon dioxide snow melts to drain away.

Advantageously, the lower part, the lid and the transverse plates of the packaging according to the innovation are all made of foamed Made of polystyrene. However, any other appropriate material can also be used within the scope of the innovation.

The innovation also includes the following specified features and their various possible combinations.

In the accompanying drawings, two embodiments of packaging according to the innovation are only given as examples for explanation

shown, namely show:

1 shows a cross section of a first embodiment of a packaging according to the innovation seen from the front, with the lid, a transverse plate and the lower part separated from one another are shown;

FIG. 2 shows a detail of the packaging of FIG. 1, with the lid is in its closed position on the lower part;

FIG. 3 shows a plan view of the lower part of the packaging of FIG. 1;

4 shows a section corresponding to FIG. 2 of a second embodiment of the packaging according to the innovation, tiie differs from that first differs only by the device for holding the cover and base together.

The packaging shown in Figures 1 to 3 consists essentially made up of a lower part 1, a cover 2 and a plurality of transverse plates 3.

The lower part 1 and the cover 2 each have a U-shaped Cross-section, and their cavities face one another »

The lower part 1 is provided with a plurality of transverse grooves 4, which are arranged at regular intervals in the inner surfaces of the base 5 and the side walls (flanks) 6 of the lower part 1 in each case continuously are trained. The lid 2 is provided on the inside of its bottom 7 with a plurality of transverse grooves 8, the have the same regular intervals and dimensions as the grooves 4 of the lower part 1.

The lower part 1 and the cover 2 consist of sections which are shaped by a transverse cut through (not shown)

te elements made of expanded polystyrene substantially in the middle of the part located between two adjacent grooves 4,8 are made.

In the embodiment shown, each transverse plate 3 is flat and its thickness is substantially equal to the width of the grooves 4.8 of the base and lid.

Each transverse plate 3 is slightly oversized with respect to the space between the base of the in the side walls 6 of the lower part lying portion of the grooves and with respect to the free height between the bottom of the floors 5,7 of the lower part 1 and Cover 2 formed sections of the grooves 4.8 in the ver f

Final position of the cover 2 on the lower part 1. !

In the embodiment shown in FIGS. 1 to 3, each transverse plate 3 essentially closes when the packaging is closed Hermetically to the lid 2 and lower part 1 of the package because of the compression or compression of the edges of the transverse plate against the walls of the grooves 4,8.

The side walls (flanks) 9 and 6 of the cover 2 and lower part carry corresponding holding devices around the cover 2 to hold the lower part 1. These holding devices consist of a longitudinal groove 10 of rectangular cross-section in each side wall 6 of the lower part 1, which extends over its entire length and into which a projection or a rib 11 (Figure 2) penetrates, which protrudes from each side wall 9 of the cover 2. The nose 11 also extends over the entire length of the cover 2 and protrudes inward in a direction parallel to the plane of the base of the cover 2.

So that the lid can more easily get into its closed position,

tk * * · ι

after it has been placed on the lower part 1 previously provided with its transverse plates 3 and filled with the products to be packaged is placed so that its grooves are opposite the transverse plates 3, the upper outer parts of the side walls β of the lower part beveled in order to form bevels 12 which act as guide surfaces.

When the user exerts vertical pressure on the cover 2, slide the lugs 11 over the guide surfaces 12, whereby the Side walls 9 of the lid are elastically pressed apart, and the elasticity of the material brings the side walls back into their starting positions when the lugs 11 penetrate the grooves 10. In the closed position of the cover 2, the bottom presses the same at the same time against the upper edges 13 of the side walls 6 of the lower part 1 and the upper edges of the corresponding Transverse plates 3 engaging grooves 8 of cover 2 and optionally with correspondingly profiled bearing surfaces 14 against the guide surfaces 12.

The closure of the lid 2 on the lower part 1 is thus practical invulnerable, since the deformation of the side walls of the base under the effect of the weight of the items contained in the package Products brings about an intimate contact of the side walls with those of the lid, which form stops and this Counteracts deformation.

If the transverse plates 3 do not penetrate into the grooves 8 of the cover 2, especially if the height of the transverse plates is reduced to allow air circulation in the package the lid 2 can be brought into its closed position by

after longitudinal insertion of the lugs 11 into the grooves 10 like a Slide open the drawer.

In the embodiment shown in FIG. 4, there is the holding device from additional support surfaces 15,16 with S-shaped Cross-section, the task of which corresponds to the projections 11 and Grooves 10 is the embodiment described above.

The grooves 10, projections 11 and the bearing surfaces 12,14 of the The lower part 1 and cover 2 of the packaging of FIG. 2 can be produced both directly by shaping the lower part 1 of the cover 2 as obtained by machining them. The same also applies to the embodiment according to FIG. 4.
