Packaging for objects in the shape of a parallelepiped, a cube or the like, in particular for household appliances.

The innovation relates to a packaging system for articles in the shape of a parallelepiped or cube, in particular (but not necessarily) for household appliances (such as cookers), where this packaging system comprises a plurality of corner parts made of reinforced expanded material, as well as a base part.

Such a packaging system for household appliances such as refrigerators, washing machines, etc., which is designed in particular to store or transport at least two stacked appliances without damaging their relatively fragile or damageable surface, is already known.

This known packaging system has four corner parts made of expanded polystyrene (or similar material) into which bolts or metal rods are embedded as longitudinal reinforcement elements, as well as a base part made of expanded polystyrene into which metal profile parts are embedded near the corners and against which the

Press the reinforcement bars of the corner pieces.

The packing system is completed on the top by a profiled plate, also made of expanded material, provided with slots in which somewhat projecting rigid strips are provided to abut against the ends of the embedded reinforcements in the corner parts. A packing system of this type is known from Italian patent no. 1,077,140 = DEGM 780336. This known type of packing is relatively complicated and the parts, and in particular the corner parts, can only be manufactured relatively slowly because of the need for the exact position of the metal joining parts.

The innovation now has the task of creating a packaging system of the type mentioned at the beginning, in which a substantial structural strength, for example against combined bending and compression forces, is combined with resistance to impact forces, thereby avoiding damage to the relatively vulnerable parts of the device, such as the upper surface of the housing, and which consists of parts

which are simpler, can be produced more quickly and take up less volume. And of those made of expanded material, which are more easily damaged, are fewer in number and have a smaller total volume. The packaging system according to the innovation has the characteristic that the corner parts made of expanded material are reinforced by | angle parts which are attached to the outside by gluing.

Preferably, the angle parts are made of pressed Layered material based on plastic, paper and possibly metal.

The packaging system suitably comprises a cardboard container as the base part, a pair of angle parts resting in a simple manner on two sides of the container, a few profiled spacers on the other sides of the container, four corner parts reinforced with angle parts, a cover plate and a lid in the form of a container corresponding to the base part. After the household appliance has been packed, the whole is placed in a wrapping made of I

wrapped in heat-shrinkable plastic, which is then shrunk in a known manner, thus stabilizing the whole thing.

An example of the innovation is in the

drawing and is described in more detail below. The drawing shows a packaging system in a diagrammatic, exploded view.

The new packaging system features:

a) a rectangular base part 1 in the form of a cardboard container with side walls that can be folded down;

b) four corner parts 2, of which only one is visible in the figure;

c) two angle parts 3,4;

d) two side spacers made of expanded material 5,6; e) a flat cover element 7 made of strong corrugated cardboard;

f) a cardboard container 8 with side walls that can be folded down and which at least almost corresponds to the base part 1.

The expanded polystyrene

Side spacers have recesses at the corners to accommodate the four corner pieces 2. They rest on the bottom of the bottom part 1 and svsr on the short sides and there are rabbits IC sas of the boaen part angled upwards to hold the side pieces in place. The purpose

of the angle parts 3 and 4 is to resist the lateral pressure exerted on the packaging when it is gripped by a jaw gripper,

The spacers 5,6 are placed after the angle pieces 3,4 in the base part 1.

The angle parts can be made of wood or plastic

but they preferably consist of a known layered material based on plastic, paper, cardboard and possibly thin metal layers

The corner parts 2 are made of an L-shaped expanded

Polystyrene core, the outer corner of which is suitably cut away to accommodate a reinforcing angle element 2A which is able to withstand the combined bending and compression loads and which is fixed to the core 2B by adhesive. The

.15 The material of the angle element 2A can be one of the materials specified for the angle parts 3,4.

The household appliance to be packed is placed centrally in the base part 1 after parts 3, 4, 5 and 6 have been arranged in it. The corner parts 2 are then attached in such a way that the lower ends are between the side wall of the base part and the

The corrugated cardboard plate 7 is then placed on the Device and the corner parts 2 are placed, after which the lid 8 is placed on top. Finally, the whole thing is wrapped in heat shrink plastic, which

is made to shrink in a known manner. j

The resulting packaging system effectively protects the household appliance contained therein against the hazards normally associated with the handling and transport of

household appliances, which was achieved by reducing the use of relatively expensive parts made of expanded j

Polystyrene foam (the volume of which causes problems before use and | when handling the parts due to their fragility or the 7 light J

crumbling). j In the new packaging system, the j

vertical pressure forces are absorbed by the angle elements 2A of the corner parts. The lateral forces, as exerted by the jaw grippers, are absorbed by the angle elements 3 and 4 and the cover plate 7.
