According to the invention, when the packaging is formed, the first upper part (4) is folded so as to form a closing surface (12), said at least one flap (8) and the end (3a) of the panel. front (3) being folded opposite one another so as to form a gripping member (13) projecting beyond said closure surface (12).

The invention relates to a cardboard packaging for mobile equipment, as well as mobile equipment comprising such packaging.

In particular, the invention can be applied to mobile equipment for transporting fluid containers, in particular mobile equipment which can be used in a work operation of the oxyacetylene type.

Documents FR-A-2873644 and FR-A-2802281 are known in particular for mobile equipment for transporting containers of pressurized fluid. This mobile equipment includes rolling carts with a support structure for carrying the containers and several wheels to allow the carriage to move on the ground. Line handle conventionally allows an operator to direct this movement.

Such mobile equipment is commonly used in flame working operations, in particular welding, cutting or brazing processes, and more particularly for processes of the oxyacetylene type, carried out using torches whose energy is produced. by the simultaneous combustion of two gases, oxygen (CE) as oxidizing gas and acetylene (C2H2) as combustible gas. They are commonly called "work stations" or "welding stations". Another combustible gas can also be used in place of, or in addition to, acetylene, for example propane, propylene, butane ...

Usually, mobile equipment with rolling carts, after assembly in the factory, packaged in cardboard packaging or in a plastic cover. This protects the equipment from atmospheric contaminants (dust, humidity, etc.) during transport to end users.

However, conventional packaging poses difficulties during the transport and handling of equipment which is fully packaged there. It is not possible to roll them, which requires lifting the equipment to move it, mobile welding equipment being able to weigh several tens of kilograms. In addition, the ventilation of the equipment during storage or transport is not satisfactory.

The technical problem is therefore to overcome all or part of the drawbacks mentioned above, in particular to provide packaging making it possible to effectively protect mobile equipment, while offering easier handling of the equipment once packed, and which ensures in addition to efficient ventilation of the mobile equipment, and in particular is easily adaptable to mobile flame work equipment.

The solution of the invention is then a packaging for mobile equipment, said packaging being formed by folding a cardboard blank comprising:

The invention also relates to mobile equipment comprising such packaging. The equipment advantageously comprises a rolling cart carrying at least two containers of fluid, preferably at least a first container containing a combustible gas such as acetylene and a second container containing oxygen.

According to another aspect, the invention relates to a method of packaging mobile equipment using a packaging according to the invention, said method comprising a first step of forming the packaging by folding the blank and a second stage of arrangement of the packaging by threading around the mobile equipment.

The invention will now be better understood thanks to the following detailed description, given by way of illustration but not limitation, with reference to the appended figures among which:

Figure 1 illustrates mobile conventional welding equipment, Figure 2 illustrates a blank for forming a package according to one embodiment of the invention, and Figure 3 illustrates mobile equipment packaged in a package according to the illustrated embodiment by Figure 2.

In the context of the present invention, the containers are containers of pressurized fluid, that is to say pressurized containers. The fluid can be in the gaseous, liquid or two-phase liquid-gas state.

Figure 1 illustrates an example of mobile equipment 70 to which the invention can be applied. It is a welding station comprising a rolling cart supporting first and second containers 50, 60 of pressurized fluid. These receptacles are provided with taps at their upper end. Work equipment, such as a welding torch, can be associated with the welding station, and placed on the assembly formed by the carriage and the containers. It is necessary to protect all of the shocks and dust when transporting and storing the equipment.

To do this, the invention relates to a packaging formed from a cardboard blank 30, an exemplary embodiment of which is illustrated in FIG. 2.

By "blank" is meant a cardboard structure arranged substantially flat and intended to form the packaging after folding and shaping.

According to one embodiment of the invention, the blank 30 comprises first and second side panels 1, 2 and a front panel 3. The blank 30 may further comprise a rear panel 16. In FIG. 2, the side panels 1, 2 are arranged on either side of the front panel and connected to said front panel by vertical fold lines. When forming the package, the back panel is connected by a bonding line with an appropriate adhesive. Of course, in the context of the invention, the folding and gluing lines can be arranged between different panels of the blank 30. Said panels then follow one another, in a flat representation such as that of FIG. 2, in a different order along the lateral direction (arrow x).

The blank 30 comprises a first upper panel 4 connected by a first upper fold line 9 to the first side panel 1. The blank 30 may further comprise a second upper panel 5 connected by a second upper fold line 10 to the second panel lateral 2. In this case, when the package 100 is formed, the first and second upper parts 4, 5 are folded so as to each form a part of the closure surface 12. Alternatively, the blank 30 may comprise a single upper panel 4 which, in the folded position, forms the closing surface 12.

As shown in Figure 3, once formed and arranged on the mobile equipment 70, the package 100 extends generally in a vertical direction z and the side panels in a horizontal direction x perpendicular to the direction z. Advantageously, the closure surface 12 extends in a substantially horizontal plane perpendicular to the planes in which the side panels 1, 2 extend. The upper end 100a of the package 100 is thus advantageously completely or almost entirely closed. by the closing surface 12, which protects the equipment from dust. Preferably, the lower end 100a of the packaging 100 remains open, which ensures good ventilation and allows, after shaping, to facilitate the positioning of the packaging 100 by threading from above the equipment. mobile 70.

Figure 3 shows the package 100 shaped with the side panels 1, 2 folded on either side of the front panel 3 and arranged substantially perpendicular to said front panel 3.

In all cases, the front panel 3 comprises an end 3a extending, in the direction z, beyond the upper fold lines 9,10. A flap 8 is connected by at least one front folding strip 11 to the end 3a of the front panel 3. The package 100 is formed by folding the flap 8 in the direction of the closure surface 12 until the flap 8 is located opposite the end 3a

This makes it possible to form, with the flap 8 and the end 3a, a gripping member 13 projecting from the closure surface 12. The gripping member 13 facilitates the rolling of the mobile equipment 70, even packed in the packaging 100, and also allows effective protection of the equipment 70 thanks to the folding strip 11 which also participates in the closing of the packaging 100 and greatly limits the entry of atmospheric contaminants.

Advantageously, the first and / or second upper panels 4, 5 comprise fastening means 6, 7, 8a configured to fasten the flap 8 and the closure surface 12. This fastening is preferably reversible.

According to a preferred embodiment, the securing means 6, 7, 8a comprise notches 6, 7 arranged respectively on the first and second upper panels 4, 5. An upper edge 8a of the flap 8 is configured to be inserted at least in part in the notches 6, 7. Preferably, the notches 6, 7 are arranged on the edges of the upper parts 4, 5 arranged on either side of the end 3a.

Preferably, the edge 8a is also movable around a fold line relative to the flap 8, the edge 8a being held in abutment against the inside of the closure surface 12 when the edge 8a is inserted in the notches 6, 7.

A first and a second opening 14, 15, preferably of oblong shape, are arranged in the end 3a of the front panel 3 and the flap 8 respectively so as to facilitate manual gripping for the gripping member.

The packaging according to the invention is advantageously intended for mobile equipment 70 provided with at least one handle 90. According to a preferred embodiment, the flap 8 and the end 3a of the front panel 3 extend, when the packaging is formed and packages mobile equipment 70, on either side of handle 90 with said front folding strip 11 resting in abutment on handle 90. The packaging is thus kept on the equipment at a height by relative to the ground which can be adjusted by dimensioning the end 3a.

As shown in Figures 2 and 3, the front fold strip 11 is formed by two lines of secondary folds. This makes it possible to produce a folding strip of a certain thickness, typically a thickness substantially equal to or greater than that of the handle 90.

Advantageously, the blank 30 can comprise several secondary fold lines in order to be able to adjust the positioning height of the same blank as a function of the height of the mobile equipment to be packaged.

Optionally, the side panels 1, 2 may include one or more orifices 22 advantageously ensuring air circulation inside the package 100.

Preferably, the first and second side panels 1, 2 comprise, at their lower ends 1a, 2a, cutouts 41, 42 shaped to allow the passage of the wheels 40 outside the packaging.

As seen in Figure 3, the wheels 40 can thus protrude outside the packaging, which allows to maintain a free space between the first and second side panels 1, 2 of each equipment, when said equipment is placed against each other during transport or storage. This ensures good ventilation of each station by leaving the openings 22 of said side panels 1, 2 free.

Advantageously, the packaging 100 and the mobile equipment 70 are dimensioned so that the wheels 40 of the carriage project from the external surfaces of the first and second side panels 1, 2.

The cardboard blank 30 further comprises a rear panel 16 comprising a third upper part 17 provided with a slot 19. The first and second upper parts 4, 5 are connected to flaps 20, 21 by secondary fold lines , the rear panel 16 into which, when the packaging is formed, at least part of the flaps 20, 21 can be inserted. This allows better retention in the closed position and improves the robustness of the packaging.
