Description

Anti-scratch packaging suitable for a heavy object

The present invention relates to a packaging suitable for at least one object, the packaging comprising at least two movable packaging parts between a closed configuration, in which the two packaging parts at least partially define a housing adapted to receive the object, and an open configuration, in which the two packaging parts are spaced from each other relative to the closed configuration to allow removal of the object from said housing.

The object is for example an acoustic enclosure or an electroacoustic amplifier.

The invention also relates to a set of such an object and such packaging.

Document EP 3 160 856 describes such packaging. The two packaging parts respectively comprise a shell of soft material, such as polystyrene, advantageously forming an imprint of one half of the object to be packaged. In order to avoid any micro-scratches on the object, it is also wrapped in a protective cover. This cover is removed to make the object visible, and must in principle be replaced on the object if you want to repack it. Such packaging is satisfactory from the point of view of protecting the object during transport and / or storage.

However, there is a risk that a foreign body could slip into the cover and cause micro-scratches on the object, especially if the object has been repackaged.

An object of the invention is therefore to provide a packaging as described above which, while remaining suitable for the object, avoids or reduces the risk of the formation of micro-scratches on the surface of the object.

To this end, the subject of the invention is a packaging of the type described above, in which the two packaging parts comprise a body, and a member fixed on the body and intended to be in contact with the object in the closed configuration, the body having:

- a first surface, and

- A second surface defining a hollow in the body relative to the first surface, at least a portion of the member being elastically deformable between a rest position relative to the body, occupied in the open configuration and in which said portion forms a flat surface in continuity with the first surface, and a deformed position, intended to be occupied in the closed configuration when the object is received in the housing.

According to particular embodiments, the packaging includes one or more of the following characteristics, taken alone or in any technically possible combination:

the organ comprises a membrane comprising the portion, the first surface of the body forming a frame on which at least a portion of the membrane is stretched, the flat surface extending across the frame in the rest position, the membrane being intended to marry at least partially the object in the closed configuration;

- For each of the two packaging parts, the first surface extends in a plane defined by said plane surface in the open configuration, and is covered by the membrane;

- for each of the two packaging parts, the first surface has a straight edge on which the membrane forms an edge;

- The two packaging parts are pivotally mounted with respect to one another about a pivot axis, the pivot axis being parallel to the edge of each of the two packaging parts;

- The body comprises an outer layer preferably made of cardboard, a wedging block having a honeycomb or foam structure, and optionally an inner shell intended to call the object covered with the membrane in the closed configuration;

- the membrane is threaded elastically on the wedging block;

- the membrane comprises, by mass:

- between 76% and 92% of polyester, preferably between 78% and 88%, and

- between 8% and 24% of elastane, preferably between 12% and 20%;

- at least the stretched part of the membrane is made of a textile of which a rectangle of 320 mm by 270 mm maintained in a horizontal frame stretches more than 60 mm vertically under the action of a weight of 2.5 kg subject to gravity, the weight being cylindrical and having a base with a diameter of 180 mm placed in the center of the rectangle; and

- at least the stretched part of the membrane is made of a textile providing a result greater than 4 when this textile is tested at 40 ° C according to ISO standard 105-C06 of 2010.

The subject of the invention is also an assembly of at least one object, preferably an acoustic enclosure or an amplifier, and of a package as described above, the two packaging parts being in the closed configuration, l the object being received in the housing defined by the two packaging parts, the member being in the deformed position and being in contact with the object.

The invention will be better understood on reading the description which follows, given solely by way of example, and made with reference to the appended drawings, in which:

FIG. 1 is an exploded perspective view of a package according to the invention,

FIG. 2 is a perspective view of an assembly according to the invention, in the open configuration, the assembly comprising the packaging shown in FIG. 1, and

- Figure 3 is a view of the assembly shown in Figure 2, in the closed configuration, and in section along a vertical plane perpendicular to the contact plane of the two packaging parts in the closed configuration.

With reference to FIGS. 1 to 3, an assembly 1 according to the invention is described.

As shown in Figures 2 and 3, the assembly 1 has for example a parallelepiped shape. The assembly 1 rests on a surface S, for example substantially planar and advantageously horizontal, in a direction of support D perpendicular to the surface S, that is to say vertical in the example shown.

The assembly 1 comprises an object 5, and a packaging 10 suitable for packaging and unpacking the object.

Object 5 is for example an acoustic enclosure. In the example shown, the object has a generally globular shape, oblong in a direction L (Figure 2).

As a variant, the object has any general shape, usual or not, for an acoustic enclosure.

Object 5, for example, has a mass of between 2 and 25 kg.

According to a variant not shown, the object is any object in the field of acoustics or consumer electronics, for example an amplifier.

The packaging 10 comprises two packaging parts 10A, 10B movable between a closed configuration (FIG. 3), in which the two packaging parts define a housing 12 adapted to receive the object 5, and an open configuration (FIG. 2) ), in which the two packaging parts are spaced from each other relative to the closed configuration to allow removal of the object from this housing.

The package 10 advantageously comprises a base 14 adapted to serve as a support for the object 5 in the open configuration and to close the housing 12 in the direction of support D towards the surface S in the closed configuration.

The packaging 10 comprises a connecting member 16 (FIG. 1) adapted to make a pivot of the packaging part 10A relative to the packaging part 10B around a pivot axis D1 advantageously perpendicular to the surface S.

The set includes for example other elements (not shown) for fixing the packaging parts to one another in the closed configuration, such as a case threaded onto the packaging parts, or paper adhesive suitable for joining the packaging parts to each other in the closed configuration.

As the packaging parts 10A, 10B are, in the example shown, structurally analogous to each other and symmetrical to each other with respect to a plane P defined by the support direction D and the longitudinal direction L, only the packaging part 10A will be described in detail below.

The packaging part 10A comprises a body 18, and a member 19 fixed on the body and adapted to be in contact with the object in the closed configuration.

In the example shown, the member 19 is constituted by a membrane 20 adapted to at least partially match the object 5 in the closed configuration.

According to a variant not shown, the member 19 comprises, instead of a membrane, a plate connected to the body 18 by springs.

As visible in FIG. 1, the body comprises, successively from the housing 12, located inside the packaging, towards the outside, an internal shell 22, a wedging block 24, a frame 26 and an external layer 28.

The body 18, in the assembled state, has a first surface 30, advantageously forming a frame on which a part 32 of the membrane 20 is stretched, and a second surface 34 defining a hollow 36 in the body 18 relative to the first surface 30, the recesses 36 of the two packaging parts 10A, 10B partially delimiting the housing 12 in the closed configuration.

The internal shell 22 is adapted to wedge the object covered with the membrane in the closed configuration. The internal shell is for example made of polystyrene, advantageously of sweetylene, or alternatively of acrylonitrile butadiene styrene (ABS).

The internal shell defines the second surface 34 in the example shown.

The wedging block 24 is advantageously a honeycomb or foam structure suitable for receiving, on one side in a transverse direction T perpendicular to the support direction D, the internal shell, and for fitting on the other side in the outer layer 28.

The wedging block 24 defines the first surface 30.

The frame 26 is for example made of polyurethane foam. The frame 26 is advantageously adapted to keep the wedging block 24, the internal shell 22 and the member 19 transversely in the closed configuration. The frame 26 advantageously absorbs the manufacturing tolerances of these elements in the closed configuration.

The outer layer 28 is for example of cardboard.

The first surface 30 is for example entirely covered by the membrane 20. The first surface has a straight edge 38 on which the membrane forms an edge 40 advantageously parallel to the pivot axis D1.

A portion 42 of the member 19 is elastically deformable between a rest position (Figures 1 and 2), occupied in the open configuration and in which the portion 42 forms a flat surface 44 in continuity with and across the frame defined by the first surface 30, and a deformed position (Figure 3), occupied in the closed configuration when the object 5 is received in the housing 12. The portion 42 is reversibly deformable from the rest position to the deformed position.

By "in continuity" is meant here, for example, that the edges of the two surfaces considered are opposite one another. In the example shown, the edges of the two surfaces are advantageously combined and the continuity is then perfect.

The planar surface 44 defines a plane P ′ in which the first surface 30 advantageously extends.

The part 32 of the membrane stretched over the frame is advantageously entirely located in the plane P ’.

The membrane is for example elastic over its entire surface. The membrane is advantageously threaded elastically on the wedging block 24.

The rear face 46 is opposite transversely to the first surface 30.

On the rear face 46, the membrane defines for example an opening 48 delimited by an edge 50.

The opening 48 is less extensive than the body 18 in all directions parallel to the plane P ’.

The membrane comprises, for example, in mass:

- between 76% and 92% of polyester, preferably between 78% and 88%, and

- between 8% and 24% of elastane, preferably between 12% and 20%.

The membrane has, for example, a surface mass of between 120 and 160 g / m ² .

The membrane is for example black in color in order to highlight the lighter object in the open configuration.

Advantageously, at least the stretched part 32 of the membrane is made of a textile providing a result greater than 4 when this textile is tested at 40 ° C according to ISO standard 105-C06 of 2010.

Advantageously, at least the part 32 is made of a textile which stretches over a distance E greater than 60 mm when it is subjected to a test shown diagrammatically in the figure.

4.

In this test, a rectangle 54 of the textile is kept horizontal and without tension between the jaws 56, 58 of a frame 60.

Then a cylindrical weight 62 having a diameter D2 of 180 mm and a mass of 2.5 kg is deposited in the center of the rectangle 54.

Under the action of gravity, the weight 62 deforms the textile rectangle 54 vertically over the distance E.

If a mechanical characterization of the membrane is carried out in accordance with standard NF EN 14704-1 of June 2005 (Determination of the elasticity of fabrics - Strip test), the following results are obtained for example:

1) in the direction of the column (or chain) of the meshes of the membrane:

- Maximum elongation in the 5 ^th cycle: 165.4%

- Force (N) under 25% elongation in the 5 ^th cycle go: 0.7 N,

- Residual elongation after one minute: 10%,

- Elastic recovery: 54.4%.

Advantageously, the value (100% / maximum elongation at the 5 ^th cycle in%) * 100% - Elastic recovery in% is less than 8%.

In the example above, this value is 100% / 165.4% * 100% - 54.4% = 6.05%, which is less than 8%.

2) in the row (or weft) direction of the mesh of the membrane:

- Maximum elongation in the 5 ^th cycle: 216.3%

- Force (N) under 25% elongation in the 5 ^th cycle go: 0.7 N,

- Residual elongation after one minute: 16%, and

- Elastic recovery: 38.8%.

Advantageously, the value (100% / maximum elongation at the 5 ^th cycle in%) * 100% - Elastic recovery in% is less than 8%.

In the example above, this value is 100% / 216.3% * 100% - 38.8% = 7.43%, which is less than 8%.

Thanks to the characteristics described above, the members 19 of the packaging parts 10A, 10B effectively protect the object 5 against micro-scratches which could be caused by the internal shell 22 in the closed configuration.

If a foreign body (not shown), such as a solid particle, is present on the deformable portion 42, this foreign body generally falls when the packaging is placed in the open configuration. The probability that a foreign body becomes fixed on the portion 42 is also reduced in the open configuration, this portion not being a container, but a surface with a strong inclination, advantageously vertical.

In addition, the members 19 constitute a protection which remains integral with the bodies 18 of the two packaging parts 10A, 10B and cannot be lost, unlike a removable cover.

Finally, in the open configuration, the deformable portion 42 constitutes a flat and uniform surface, "magically" masking the hollows 36. This allows a particularly aesthetic and impressive presentation of the object when it rests on the base. 14 in the open configuration.

Advantageously, in the embodiment where the member 19 comprises the membrane 20, the latter at least partially matches the object 5 in the closed configuration, which improves the protection of the object.
