Description

PACKAGING FOR DANGEROUS GOODS

Technical field

The present invention relates to a package intended, in particular, for wrapping dangerous goods, for example goods containing gunpowder and gas cartridges as part of the package.

BACKGROUND OF THE INVENTION

Safety airbags and safety belts for cars containing gunpowder and gas cartridges cause spare parts, in terms of transport, of the problem of being referred to as pyrotechnic articles and as such for the transport of dangerous goods. For this reason, such spare parts must be stored in special designated locations and distributed separately, sometimes not

for their transportation lines. possible use nor ordinary aerial / Usually for packing corrugated cardboard boxes, this whose type of goods used the inner space is

filled with polystyrene or polyethylene foam.

Other problems are caused by financial costs and longer delivery times, so there remains a serious demand for the creation of a special packaging acceptable to the competent authorities for normal shipment and at the same time. 9

9 · «9 met the requirements for the storage of dangerous goods of the above-mentioned or similar type.

One of the essential requirements for such a package is that it must be able to withstand and resist direct fire for at least 30 minutes while providing a well-defined protection of the goods contained therein against the shock and vibration experienced, for example, in the event of a package drop from a certain height.

SUMMARY OF THE INVENTION

According to the present invention there is provided a package meeting the above requirements and providing a solution to the problems associated with commonly used packages, characterized in that it consists of an outer box of fire resistant rigid cardboard;

compressed slag wool inner cassettes; and wire frames or wire cages arranged around the inner shell.

In order to comply with the respective packaging requirements, the cardboard from which the outer box is formed typically has a weight of 1150 g / m ² and the fibrous slag wool from which the inner cassette is formed, typically a bulk density of 115 kg / m ³ .

The inner cassette consists of two parts: a bottom part and a lid, provided with circumferentially aligned and mutually aligned projections and grooves, and has a material thickness of which it is made, which is typically 40 mm, except for the sides provided with said fasteners; Fefe Fefe Fefe Fefe Fefe Fefe Fefe Fefe Fefe typically having a thickness of 60 mm.

Three wire frames can usually be used for packaging. These frames can be made of steel wire, typically 3 mm in diameter.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention will be explained in more detail by way of a detailed description of its specific embodiments with reference to the accompanying drawings, in which:

FIG. 1 is a perspective view of the individual components of the package according to the present invention; and FIG. 2 shows a corresponding representation of said components of the package, but in a partially assembled state and with partial removal of one of its components to provide a view of the storage space of the package.

DETAILED DESCRIPTION OF THE INVENTION

Characteristic examples of goods for which the package according to the present invention is intended are safety air bags and safety belts containing gunpowder and gas cartridges. Such goods are referred to as dangerous goods and special packaging is required for their packaging.

The package of the present invention comprises substantially

The combination of the three basic components: outer box 1, inner cassette 2, and wire frames 3.

The outer box 1, which is shown in the unfolded non-functional state in Fig. 1 and in the collapsed functional state in Fig. 2, is made of a fire-resistant impregnated rigid cardboard, typically weighing 1,150 g / m ² . This box preferably has a parallelepiped configuration. It is preferably of the glued type and is assembled or closed by means of steel clips or staples (not shown).

The inner cassette 2, the outer contour of which corresponds to the inner contour of the box 1, is made of pressed slag wool or a similar fibrous material which, in a specific example, contains oxides such as silicon oxide, iron oxide, aluminum oxide and calcium oxide, a refined phenol-formaldehyde resin as a binder, and a binder and maintenance agent in powder form, which both allow the slag wool to be pressed and maintain its contour shape. The bulk density of this material may be of the order of 115 kg / m ³ .

The inner cassette 2 is generally formed of two parts: a lower part 2A and a lid 2B, which, as can be seen from the figures, are preferably provided with circumferentially aligned and mutually aligned projections and grooves intended to fix and strengthen the cassette. The height of the projections may be of the order of 15 mm.

The storage space defined inside the cassette 2 will be dimensioned according to the dimensions to be stored in the cassette. The wall thickness of the inner cassette 2 is usually at least 40 mm, except for its sides provided with connecting elements, the thickness of which is usually at least 60 mm.

Before inserting the inner cassette 2 into the box 1, this cassette is provided with, for example, three wire frames 3 which serve to bind the two parts of the inner cassette 2 together and to strengthen it, which can be made of welded and machined steel wire. diameter 3 mm.

Alternatively, instead of said wire frames, a wire cage formed in these frames may be used in which the frames are joined together using any suitable means.

For the purpose of illustrating the practical size of the package, it may be noted that the external dimensional dimensions of the box 1 forming part of the package intended to wrap a safety air bag for passenger cars may be, for example, about 300 x 250 x 500 mm.

The package according to the present invention is designed and intended primarily for the purpose specified above. However, this package can also be used for other pyrotechnic articles having an explosive performance of up to 300 g of tear force.

The package of the present invention provides the following advantages:

The corresponding spare parts packaged in this package are easy and convenient to handle both in the production plant and in the storage areas.

Packaging can be transported without any obstacles and restrictions by air, rail, automobile and sea transport, and together with other types of spare parts.

Packaging significantly reduces the cost of shipping.

The packaging is reusable, particularly due to the impregnated outer surface of the box.

The packaging is very environmentally friendly and can be recycled.

The packaging is fireproof and allows customary, easy labeling and labeling.
