FR2607112A1 - PACKAGING COMPOSITE, SEMI-RIGID WITH DIFFERENTIAL DAMPING INCORPORATED - Google Patents

Abstract

Parallelepipedic packaging made of semi-rigid material or similar, comprised of an element forming an outer shell and two composite elements forming a damping receptacle characterized by a single damping on the side faces and a double damping on the top and bottom faces. The packaging has a variable damping function adapted to the various fragility degrees of different contents, with reinforcement at the positioning points of the bottoms and lids. Said packaging is perfectly adapted to and in conformity with the packaging requirements of dangerous materials and/or materials of which maritime, air or road transportation is controlled by regulations, independently of the nature and mode of preconditioning of said materials, and said packaging comes also within the packaging requirements of all fragile materials or items.

Description

<U> COMPOSITE PACKAGING, DIFFERENTIAL <U> INCORPORATED </ U> DIFFERENTIAL SEMI-RIGID </ U>.

The present invention consists of a composite receptacle package, semi-rigid plastic or similar variable damping, intended to ensure optimized protection of its contents in all transport operations, handling or storage and incidents likely to occur during these.

Such packaging will be used for the transport of fragile or dangerous materials, solid, fluid or gaseous. Hazardous materials are defined in particular as such by the following regulations: Safety rules applicable to the carriage by air of dangerous goods, defined in the convention of CHICAGO relating to civil aviation (ICAO), taken over by IATA (Transport Association Air International) and issued from United Nations (UN) recommendations.

Such a packaging is intended to receive all types of preconditioning, such as containers glasses, metal, sandstone, plastic, aluminum, textile, paper or other, regardless of their mode of opening, their content, the degree of risk of this- ci, including some radioactive products.

These products may be of a density lower, equal to or greater than 1.

The system consists of three main elements. The first element (FIG. 1) is an outer casing made of plastic material, or cardboard treated against the penetration of water or other similar material, of square or rectangular base and of variable height, assembled by agraphage. , bonding or thermal bonding. This envelope is made in one piece forming a shell for holding the other elements. (See diagram attached, Figure 1).

The second element (FIG. 2) is a first composite inner envelope consisting of a piece of cardboard or plastic (as above) of a single piece, on which is positioned a uniform protection of foam of constant thickness. , or alveolée as the case, and inseparable from its support. This composite sheet is folded in four different places corresponding to the height H and length Lo of the outer shell.

The third element (FIG. 3) is a second inner envelope of similar structure and composition to the first, but of slightly lower height and width (see FIG. 3) so that it can be inserted into the first inner envelope. , thus providing a unique protection on the four side faces of the package, andi: a double thickness of protection on the bottom and the lid.

In these elements, optionally a retention pocket (either flexible or rigid, such as plastic bag or metal container) containing an inert absorbent vermiculite type to prevent any propagation of leakage out of the packaging system in case of leakage or rupture inner container containing the product to be packaged. <B> <U> ASSEMBLY </ U> </ B> This is done by simply inserting it as follows: -Insert the retention pocket into the inner envelope B. Close it.

- Insert everything in the envelope A so that all the side faces are closed, the bottom and the cover then having an over-thickness.

-Thread everything in the outer shell. CHARACTERISTICS.

- High mechanical strength, including stacking by the juxtaposition of double-paroies on all sides ensuring perfect rigidity, and increased resistance to crushing. -Very high shock-absorbing power on all sides, with reinforced effect on bottom and lid, guaranteeing perfect protection in the event of a fall.

-Universal application to regulated including radioactive products.

- System providing variable damping with strengthening at the positioning points of the funds and covers (or openings). - This system consists of a strip of. plastic and a layer of damping material whose characteristic is the assembly by bonding or heat-sealing, and can be performed industrially continuously or in series. The folding and cutting of these strips can then be performed in series.

- Before use, the assembly of the outer shell and the internal components can be carried out manually without the aid of any tool (Fig 4).

- Assembled elements in their final form can be used without further reinforcement or locking (Fig 4).

- This system is perfectly adaptable and complies with the requirements of packaging of hazardous materials and / or whose maritime, air or land transport is regulated, regardless of the nature and mode of pre-publication of these.

Claims (1)

<U> CLAIMS </ U>. -1- Paralipipedic packaging made of plastic or the like, constituted by a semi-rigid element forming an outer shell FIG. 1 and two semi-rigid composite elements A and B, forming a receptacle Fig 2 and 3 damper characterized by a simple damping on the side faces = -r ales and a double damping on the upper and lower faces (Top and Bottom). -2- Package according to claim 1 characterized by its variable damping function adapted to the various degrees of fragility of the contents, with reinforcement at the positioning points of the bottoms and covers (or openings). -3- Packaging according to claim 1 characterized by a jextaposition of double semi-rigid walls on all sides ensuring increased resistance to crushing. 4. Packaging according to claim 1 characterized in that its shaping is carried out by folding, stapling, gluing or welding, operations can be performed industrially and in series. -5- Packaging according to claim 1 characterized in that the semi-rigid composite inner elements consist of a plastic strip and a layer of damping material whose characteristic is the assembly by gluing or thermmo = welding, and can be executed industrially continuously or in series.
