Protective packaging for sensitive products.

The present invention relates to a protective package for sensitive products which comprises an outer box containing a protective padding between the product and the package.

Such packages are available in many embodiments in which the empty space in the outer packaging package, such as a packaging box, is filled with, for example, paper, corrugated cardboard, bubble wrap, foam material or one of the many other possibilities. With these known packaging techniques, a sufficiently protective packaging can be assembled for each vulnerable product. However, this often means that the packaging has to be made relatively bulky in relation to the product to be protected. This is disadvantageous in the sense that the space required for transporting products packaged in this way is considerably larger and the transport costs involved are generally considerably higher.

The object of the invention is to obviate these drawbacks and to provide a package that offers the product to be packaged sufficient protection with a limited volume of the packaging material. A further object is to design the package in such a way that it is easy to adapt to different sizes within a certain range of the product to be packaged.

The package according to the invention is intended in particular

For sensitive products with a relatively large weight

I relative to the volume and / or relatively valuable I

10 products. For example, I

I computer parts, notebooks, TFT screens, plastic I

I screens and similar products. I

According to a first embodiment, I

Provided that a packaging element is placed on the bottom

I bottom plate of an I arranged close to the outer box

I comprises plastic foam material, a molded part intended

I for receiving a product and one on the mold part I

Top plate made of a plastic foam material

The shape of the molded part is such that I

it can engage the product clampingly. I

I According to a further elaboration, provision is made for I

I see that the molded part is designed such that it I

Can be adjusted within a predetermined range I

to the dimensions of the product to be packaged. With this I

I can use comparable products from, for example, other I

manufacturers or of another type with I

I differing sizes all in the same version

30 packing can be accommodated. I

It is furthermore provided that the molded part I

I has a fixed outer circumference at least one within the I

fixed outer circumference, the cutout I

I 1025430 I

A recess is intended to accommodate at least a part of the product to be packaged and wherein the molded part is deformable over at least a part of the length of the boundary of at least one recess. The molded part can be designed such that it can receive one product, but with a number of recesses, for example, also a corresponding number of products. For specific products, it is necessary that two or more recesses are provided for receiving certain parts of the product therein.

Apart from the fact that the deformable molded part makes it possible to have the package close to the product, the most important function is to absorb forces from outside and the reaction forces caused thereby between the packaged product and the packaging following therefrom. It is therefore preferred that a recess is delimited by a number of successive individual sides, wherein at least two of the sides are deformable.

Preferably, it is furthermore provided here that a part or a side of the boundary of a recess has a substantially convex course, the convex side facing the recess and wherein in the molded part behind a convex side or convex part of the boundary is a free space. An arc-shaped part of the molded part hereby comes to abut against the product, wherein the arc-shaped part 30 follows the shape of the product over a certain range, which is, for example, a straight line, and otherwise retains the arc shape or approximately the arc shape retains. These arc shape or arc shape parts are thus further stressed and shape to 1025430

practical tests have shown an excellent I

buffer for receiving at least certainly the first I

onset of bumps and shocks. I

In order to achieve this for different dimensions of the project

able to realize, it is provided that after I

a convex side or convex part of the boundary one I

or more webs of material removable in the mold part I

are provided. For this the removable tracks are ma-I

10 partially cut away from the molded part in advance. I

According to a further elaboration, it is provided that I

at the front of at least one convex side or conc

vex part of the boundary at least one removable I

15 strip of material has been applied. This strip is also at I

preferably partially cut away from the molded part. It to I

applying a removable strip on the front is I

particularly applicable to, for example, the short sides I

of a rectangle where less space behind the arc I

20-shaped part is available and therefore also less material

to be able to remove. I

The molded part is preferably of a foam material I

made and trapped between a bottom plate and I

25 is a top plate, the molded part along the periphery

border with the markings on the bottom surface of the outer box

the bottom plate is glued. The arcuate parts I

therefore I, in addition to their own bias

a static release component with respect to I

30 lower plate and upper plate, which further contributes to

the shock-absorbing capacity. I

The invention provides a second embodiment I

of the protective package which contains a number of separate I

1025430

Packaging elements, wherein a packaging element consisting of a plastic foam material is provided with at least one fully or partially convex part which is intended to abut against a product to be packaged.

This second embodiment is intended in particular to be used for larger products, for which a complete enclosure with plastic foam material would require unnecessary use of material and therefore also unnecessarily high costs.

According to a further elaboration, it is provided that the individual packaging elements are designed as corner pieces to be arranged on the product to be packaged, wherein each of the corner pieces is provided with a number of opposite convex parts or a number of angles with respect to each other convex parts or of opposite convex parts and at least one further convex part that is at an angle to the opposite convex parts.

With such corner pieces a product is clamped at corner points by engaging a corner piece with convex parts on, for example, the front and rear of a relatively flat product. The corner pieces come to lie in corresponding corners of an outer box and are thus locked in the outer box. The corner pieces can be adjusted to specific thicknesses of the products to be packaged by providing corner pieces with different distances between the convex parts. However, for this purpose, there is preferably provided a free space behind the convex parts, so that they can be compressed over a certain range. Vol 1025430

corner on the opposite corner pieces in a clamping I

According to a further I

elaboration provides that the corner pieces also in this I

have a convex part. This last clamping I

The product is realized by confinement I

of two or more corner pieces in the outer box. I

According to a still further elaboration, provision is made for I

at least one I on the outside of a corner piece

15 side is provided with removable or foldable parts. I

This makes an even greater adjustment possible

compared to the outer box. By thereby also in I

to provide that the dimensions of the outer box are in ten

installing removable or folding parts. I

For products with dimensions such that clamping I

of the product with a corner piece over none of the spec

25 specific directions of the product in a simple manner I

can take place, corner pieces with I are provided

convex parts in at least three directions. On this I

in this way the product can be clamped in the outer box

where the adjustment of the dimensions of the pro- I

30 dips over the dimensions of the outer box over a large I

range is possible. I

The invention is explained in more detail below

on the basis of the example given in the drawing, I

Figure 7 shows a plan view of a molded part mounted on a bottom plate; Fig. 2 shows a view of a molded part mounted on a bottom plate, Fig. 3 shows a top view of a second embodiment of a molded part arranged on a bottom plate, Figs. 4A-C shows three views of a first corner piece, and Figs. .5A-C shows three views of a second corner piece.

In Fig. 1, in top view, there is a molded part 2 arranged on a bottom plate 1. The molded part 2 has a peripheral edge 3 to which the respective arcuate parts 4,5,6,7 connect on the inside on each of the sides. Removable tracks 8,9 are provided between the arcuate parts 4,6, free spaces 10,11 being located between the removable parts 8,9 and the arcuate parts 4,6. Removable strips 12,13 are provided at the front at the arcuate parts 5,7. There are free spaces 14,15 between the arcuate parts 5,7 and the peripheral edge 3. The arcuate parts 4,5,6,7 with the removable strips 12,13 define the recess 16 in the mold part 2 which is intended for receiving a product to be packaged.

This embodiment is intended for receiving a rectangular product such as in particular a notebook, the short sides of which come to rest against the removable strips 12, 13 and the long sides of the arcuate parts 4, 6. The arcuate parts 4,5,6,7 are thereby pushed 1025430 outward, while

contact surfaces formed with the product to be packaged I

and the arcuate parts from the starting point

or be pressed against each other near the peripheral edge 3. I

Parts of the arcuate parts 4,5,6,7 hereby come to I

continue to be under pre-stress causing shocks I

and bumping into the package can be better absorbed

become. I

With wider and / or deeper products, the removable strips 12, 13 and / or the removable strips 8, 9, respectively, can be taken out.

Fig. 2 shows a view of a bottom plate 1 and a molded part 2. There is another one on top of the molded part

top plate, not shown in the drawing, corresponding to an I

product not protruding above the molded part 2

can have a thickness like the bottom plate 1. I

The molded part 2 is made of a plastic foam material,

such as polyethylene, with a density of I

20-40 kg / m3 and preferably from 20-28 kg / m3. The lower I

plate 1 and top plate are made of a plastic foam material

material such as polyether with a hardness I

From 20-80 kPa and preferably from 20-40 kPa and with an I

density of 20-50 kg / m3 and preferably of 20-30 l

kg / m3. The underside of the bottom plate is thereby at I

preferably provided with conical protrusions. I

With the package according to the invention, a min

The volume of the package according to the invention is so much smaller than the usual packages that the transport costs are based on the actual weight and not on the unfavorable assumed volume weight. This is an important advantage of the package according to the invention.

Fig. 3 shows a molded part 2 in which the peripheral edge 3 is provided on one side with a recess 17 and wherein recess 16 is bounded on three sides by arcuate parts 5,6,7. Two removable webs of material 9, 9 'are arranged between the peripheral edge 3 and the arcuate part 6. This embodiment is intended for a product that is made up of two distinct parts, for example a TFT computer screen, of which a first vulnerable part, the screen is placed in the recess 16 and the second less or hardly vulnerable part, for example the base of the screen, is placed in the recess 17. The distribution of the removable strips and removable tracks is tailored to the specific product, with larger deviations of a standard size in only one direction to be expected.

The associated top plate will have a greater thickness than the bottom plate in order to be able to receive the part of the foot protruding above the mold part 2. 30

The assembly of bottom plate 1, molded part 2 and top plate 17 are placed in a corrugated cardboard box, where a precise fit is important. Furthermore, it is also important that a correct type of corrugated cardboard is used 1025430

The corner piece according to Figs. 4A-C is intended for a relatively large and flat product such as, for example, a plasma screen, wherein the front and rear sides of the different angular points between the arcuate parts 26, 27 are confined and the arcuate parts 30 against come to lie on the sides. Since such a plasma screen has to be transported upright, the corner piece 18 is provided with a bottom plate 32, whereby a better distribution of the weight is obtained. Furthermore, this provides for an increase in order to be able to keep the standard of the screen at a distance from the bottom of the outer box.

Furthermore, a supporting plate 33 is provided between the arcuate parts 26, 27, 30 where the product comes to rest on the corner pieces. The supporting plate 33 is of a considerably less deformable material than the other parts of the corner piece 18, but may just as well be of a plastic foam material.

The plate parts 23,24 are provided at the rear with continuous strips 34,35 which are partially cut away from the remaining part 25 of the plate parts 23,24 along the lines 36,37. These strips can be folded or broken off to the side if a product needs to be packed that falls in the width of the maximum part of the range. This provision together with an outer box whose dimensions can be varied in at least one other direction, for example the height, ensure that the indicated flat products can be clamped into the package within a wide range. The height can be increased to 1025430 by providing an outer box consisting of two parts that can be slid over each other
