Description

7th c «Le.Le. THIS relates to the protective filler, especially for the packaging of bulky, particularly easily damaged objects.

BACKGROUND OF THE INVENTION

For large packaging. brittle, easily damaging products in crates and cartons, polystyrene foam is generally used as a protective filler. These are either pre-fabricated parts that exactly match the shape and dimensions of the packaged pieces, or the mass injected between the foil wrapper, for example polyvinyl chloride, and the outer wrapper wall. All such material is irreversible and completely unsuitable for other purposes, perhaps with the exception of foil, and is a waste that cannot be recycled for the most part. The disposal of this waste is therefore a problem since it is either landfilled or incinerated, which in both cases has a negative impact on the environment.

The essence of the technical solution

The above mentioned problem is solved by a protective filler according to ·>

wherein the infill is formed by at least one flat segment consisting of at least two panels and provided with a set of spatial formations, wherein the panels are separated from each other by mechanical weakening of the segment along a dividing line between adjacent panels. In a preferred embodiment, the segment consists of three square pieces arranged in a L-shape. You can also create segments as part of an integral file. in which the segments are

V2 separated by mechanical weakening at the dividing line between adjacent segments. According to the present invention, the mechanical weakening between adjacent segments can conveniently be performed by perforation. According to the present invention, the individual spatial formations preferably have the shape of a concave and / or convex truncated cone whose upper base can be provided with a relief opening.

The advantage of the protective filler is its universal use regardless of the size of the packaged item and its shape. It can protect both flat surfaces and corners and edges, since each segment, whether manufactured separately or separated from a unitary structure, can easily be shaped as required by the line wall weakening. Thus, it is possible to securely pack a variety of shapes without having to accurately copy all the contours of the product. The filler can be made well from natural fibrous raw materials, especially paper. This material is environmentally friendly as it is fully recyclable. At the same time, its properties ensure that the required mechanical strength and flexibility of the product is achieved.

BRIEF DESCRIPTION OF THE DRAWINGS An exemplary embodiment of a protective panel according to the present hi.Se/W »is shown in the accompanying drawings, in which: FIG. 2 is a plan view of an integral set of four segments; FIG. Fig. 4 shows a perspective view of the segment of Fig. 3 shaped for lining a corner of a packaged article; and Fig. 5 is a plan view of a rectangular base article supported by the subject protective panels. in a box of similar shape.

Execution example

The protective filler of the present invention shown in Figure 1 consists of a set of four flat segments 1, 2 each of which consists of three square pieces 2 arranged in an L-shape of the formations 3,

Each of the segments 1 arranged along is provided with a set of spatial two arms of segment 1. These convex truncated cones, the upper base of which is preferably provided with a relief hole 4. In the example shown there is one spatial formation 3 of the shape described above. The planar portion of each segment 1 is mechanically weakened at the dividing line 5, ie at the interface of the individual square parts 2, in the embodiment shown by oval recesses 6. The individual segments 1 are separated from each other by mechanical weakening at the dividing line 5 between adjacent segments 1. This mechanical weakening, allowing easy separation of the spatial formations 3 in the form of adjacent segments, is a perforation 7.

Similarly to the embodiment of the segment 1 divided by the line shown in FIGS. 1 and 2, each can be described in the manner described, i.e. by mechanical weakening of its planar part, into parts which do not necessarily have to be square or equally large. other than three. Likewise, the number of spatial formations 3 in each segment 1 may be arbitrary, and their distribution on the individual parts 2 of segment 1 may be arbitrary. It will also be appreciated that the segments 1 can be made individually or in a larger number in an integral package than described above.

When placed in crates or boxes, to secure a piece of its flat wall, it is lined with individual solid or separate segments 1 in a planar configuration. To protect the edges, the segment 1 or the entire set of segments 1 is bent around some of the transversely extending perforations 7 and the thus shaped filler is applied to the edge. 5, the segment 1 is then shaped into a shape. which is shown in FIG. 4.

packaged files,

In this case, a simple segment 1 is used, which is shown in FIG. On each of the three square parts 21,22,23, one conical spatial configuration 31,32,33 is provided. By bending the segment 1 along the first dividing line 51, between the first square piece 21 and the third square piece 23, assisted by the first oval recess 61, and then along the second dividing line 52, between the second square piece 22 and the third square piece 23, using a second oval recess 62, a rectangular shattering with convex conical formations is formed. The splinters thus formed are applied to each of the corners of the casing 11. All convex formations 3 form spacers between the walls and corners of the wrapped article and the protective wrapper, for example the box 12. The edge 53 splinters at the interface between the first square piece 21 and the adjacent edges of the two parts 21, 22 only abut one another, the shape being substantially secured by the protective cover. Similarly, objects of larger and more complex shapes can be packaged and protected from damage. In packaging, the protective filler may be applied or inserted between the wrapped article and the package in any desired manner, therefore the spatial formations 3 may also be described as concave without affecting their feasibility or use.

For the manufacture of the segments 1, a paper mass is preferred, both from the point of view of easy manufacture and from the point of view of packaging disposal. The material is not only very recyclable, but also environmentally friendly, because in the open air it disintegrates relatively quickly and is absorbed due to natural influences.
