Description

The present invention relates to the field of pallet boxes whose body is made of a semi-rigid material such as corrugated cardboard.

A box-pallet comprises a box having generally the shape of a rectangular parallelepiped, resting on a pallet, wood or other material. The crate and the pallet are integral with each other. In order to facilitate their storage before use or after delivery, it is possible to at least partially fold the body of the box on the pallet.

Several types of such pallet boxes are known and they have very wide applications in many technical sectors.

The object of the invention is to obtain a box-pallet, easy volume setting, allowing an operator to enter the box, without necessarily removing the cover, to make deposits or merchandise withdrawals without require porting of the goods to introduce it by the upper face of the box.

The invention achieves these objectives by providing a collapsible pallet box comprising a pallet and a cardboard box, or other semi-rigid material that can be folded flat on the pallet. The body comprises a first body member, comprising a central panel and adjoining side panels. The central panel and the side panels are fixed on the pallet by means of lower flaps (for example, by stapling). The pallet box also includes a second body element, internal to the body, able to strengthen the body and comprising a central panel and adjoining side panels. In the deployed position, the two central panels, respectively of the first body element and the second body element, are parallel to each other and the side panels, respectively of the first body element and the second body element, perpendicular to the central panels of the body. first and second body elements, overlap in pairs so that the opposite side to the central panels of the first and second body elements is open. The pallet box also comprises at least one reinforcement angle capable of being interposed between the first body element and the second body element so that the second body element maintains the reinforcement angle in the vertical position when the body is unfolded. The pallet box also includes a third body element. This third body element comprises a central panel capable of closing said opposite side.

The lower flaps serve to securely fasten the crate, including the first body member, to the pallet, and to unfold and fold the first body member easily.

The box thus obtained is easy to implement. Also, when the crate is mounted on the pallet, access to the interior of the crate can be made through the front panel by removing the third crate member.

In addition, this box is foldable flat on the pallet, allowing easy storage empty.

The second body element allows to maintain the angle or angles and thus to ensure the verticality of the angle or angles in place. This makes it possible in particular to guarantee the stability of the pallet in stacking.

In addition, the body is more resistant to pressure, especially vertical.

According to one aspect of the invention, the pallet box further comprises a bottom of box adapted to receive the second body member, at least a portion of the lower edges of the side panels of the second body member being configured to fit into a groove between the bottom and the first body member so that the bottom, the first body member and the second body member are locked. This allows the second member to remain in the unfolded position, thereby maintaining the first body member in the unfolded position and the body open and thus avoiding that the first body member and the second body member do not fold on themselves. This can also make it possible to wedge or block the second body element between the bottom and the first body element or between the bottom and a reinforcement angle, thus reinforcing the assembly formed in particular by the first and the second body elements. , even, and angles, if used. The second body member further allows to maintain vertical angles when they are used.

According to one aspect of the invention, at least a portion of each lower edge of side panels of the second body member, configured to fit into a groove between the bottom and the first body member, is a tenon, tenon being an extension of the lower front edge of a side panel of the second body member. The tenons allow easy insertion into the groove, thus facilitating the locking of the assembly formed by the bottom, the first body member and the second body member. According to one aspect of the invention, the first body member further includes fold lines defining a body height when the first body member is folded. These fold lines allow the tilting of the first body member between a folded position and an unfolded position. This stores the second and third body members 35 folded inside the first body member when it is folded into the storage position, thereby allowing easy storage of the pallet box which does not take and not much room.

According to one aspect of the invention, the first body member is formed of a cardboard plate, or other semi-rigid material, with fold lines delimiting a central panel and two side panels.

According to one aspect of the invention, the side panels of the first body member comprise fold lines so that the side panels are able to be folded accordion. This makes it possible to fold the first body element easily and easily. This allows more to have side panels integral with the central panel, thus strengthening the body.

According to one aspect of the invention, the first body member further comprises two flaps, extending along the side panels of the side opposite the central panel, and being adapted to retain the third body member. This keeps the third body element when it is positioned on the front of the body.

According to one aspect of the invention, at least one reinforcement angle is positioned at one of the junctions of the panels and flaps of the first body element and the third body element further comprises a flap comprising at least one groove adapted to maintain said reinforcing angle in vertical position when the body is unfolded and the flap is tilted inwardly of the body. This allows in particular to ensure the verticality of the angle (s) 20 placed at the front of the box.

According to one aspect of the invention, the second body member is formed of a cardboard plate, or other semi-rigid material, with fold lines delimiting a central panel and two side panels and is configured so that, folded in triptych, it is able to be housed inside the first folded body element. This makes it easy to store the second body member within the first body member when they are both folded.

According to one aspect of the invention, the central panel of the second body element further comprises a lower flap and is fixed on the pallet or on the bottom of the body by means of said lower flap, allowing the tilting of the central panel between a position folded and unfolded position. This makes it possible to securely attach the second body member to the pallet and to facilitate the folding or unfolding of the central panel of the second body member.

According to one aspect of the invention, the pallet box further comprises a cover 35 enabling, on the one hand, to cover the body when it is in the position of use, and, on the other hand, to cover the central panels and side panels, when folded on the pallet in the rest position.

According to one aspect of the invention, the lid further comprises two panels, articulated along a fold line, and on which are fixed shutters, openings respectively.

between the flaps in the same vertical plane parallel to the central panel of the first body member so that part of the lid can swing outwardly into an open position. This allows access to the inside of the box without removing the lid completely. This allows in particular to facilitate access to the interior of the body to an operator when the third body element is not positioned on the body.

According to one aspect of the invention, the first body member and the cover comprise notches superimposed when the lid caps the body in the use position and being able to hold the lid on the body when pierced.

In other words, the horizontal fold lines (11 ', 12', 13 ') allow the tilting of the first body member (10) between a folded position and an unfolded position. The horizontal fold lines (11 ', 12', 13 ') define the height of the box 4 in the storage position. The oblique fold lines (18, 19) allow an accordion folding of the first body member 10. Two adjoining lateral flaps (16, 17) are articulated respectively on the two side panels (12, 13) respectively along the vertical folding lines (14 ', 15'). In other words, two lateral flaps (16, 17) extend along the side panels (12, 13) on the opposite side to the central panel 11 and are able to retain the third body element 30.

In the storage position, the side flaps (16, 17) are folded, flat, under the side panels (12, 13) along horizontal fold lines (16 ', 17') and oblique fold lines ( 18 ', 19').

Figures 5 and 6 show the first body member 10 attached to the pallet 2, unfolded, and the second body member 20, partially unfolded. The box 4 comprises a bottom 50 fixed (for example stapled) on the pallet 2. The second body member 20 comprises in particular a central panel 21, on which articulates, at its ends, two adjoining side panels articulated (22, 23 ) respectively along two vertical fold lines (24, 25). The central panel 21 of the second body member 20 may be attached to the pallet 2 or the bottom 50 of the body 4 by means of a lower flap 29 allowing the tilting between a folded position and an unfolded position. The second body member 20 is configured such that, folded into a triptych, it is adapted to be housed inside the first body member 10, especially when the first body member 10 is in a folded position. The central panel 21 of the second body member 20 may further comprise a lower flap 29 adapted to allow the attachment of said central panel 21 on the pallet 2 or on the bottom 50 and the tilting of the central panel 21 between a folded position and a position unfolded. In the storage position, the side panels (22, 23) are folded, flat, under the central panel 21 along the two vertical fold lines (24, 25) and the central panel 21 is folded inwardly. the body 4. The bottom 50 of the body 4 is adapted to receive the second body member 20 in which at least a portion of each lower edge of the side panels (22, 23) is configured to fit into a groove between the bottom 50 and the first body member 10 so that the assembly formed by the bottom 50, the first body member 10 and the second body member 20 is locked. In an illustrative embodiment of the present invention, a portion of each lower edge before side panels (22, 23) of the second body member 20, configured to fit into a groove 55 between the bottom 50 and the first member 10, is a tenon 40 (26, 27) which is for example an extension of the lower front edge of a side panel

(respectively 22 and 23) of the second body member 20 as shown in Figure 16 described below. One or more reinforcement angles 60 may be placed between the first body member 10 and the second body member 20 so that the first body member 10 and the second body member 20 are integral with one another. to the other. . As illustrated in FIG. 8, one or more reinforcing angles 60 may be placed between the first body member 10 and the second body member 20 at the junction of the central panels 11 and 21 and the side panels 13 and 23 (and similarly at the junction of the central panels 11 and 21 and the side panels 12 and 22).

As illustrated in FIG. 9, one or more reinforcing angles 60 may also be placed between the first body element 10 and the second body element 20 at the junction of the lateral panels 13 and 23 and the lateral flap 17 (and similarly to the junction of the side panels 12 and 22 and the side flap 16). Thus, when the second body member 20 is unfolded and positioned inside the body, the tenons (26, 27) can wedge (ie hold, block ...) the side panels (22, 23) in a space between the bottom 50 and the reinforcement angles 60 as illustrated in FIG. 7. In an alternative embodiment of the invention, if no angle is used at the junction of the lateral panels 13 and 23 and the lateral flap 17 (FIG. or similarly to the junction of the side panels 12 and 22 and the side flap 16), the tenons (26, 27) serve to wedge (ie hold, block ...) the side panels (22, 23) in a space between the bottom 50 and the side panels (12, 13) respectively.

Figure 10 describes the establishment of the third body member 30. The third body member 30 is removable and able to close the side of the body 4 opposite the central panel 11 of the first body member 10. The third element of the body box 30 comprises in particular a central panel 31, on which articulates, on its upper edge, an adjoining hinged flap 32 along a horizontal fold line 31 '. The central panel 31 may comprise one (or a plurality) of vertical fold line (s) 34 for folding the third body member 30 in the storage position. The central panel 31 may also comprise slots or positioning holes (38, 38 ') making it possible to facilitate the positioning of the third body element 30 on the body 4 (ie to close the side of the body 4 opposite to the side of the body 4 comprising the central panel 11). As illustrated in FIG. 10, the third body member 30 is positioned on the body 4 and allows the front face of the body 4 to be closed. The plate 3 fixed on the pallet 2 serves to block the central panel 31 of the third body. body member 30 so that it completely closes the front face of the body 4 and does not descend on the front face of the pallet 2.

As illustrated in FIG. 11, the third body member 30 may comprise grooves or cuts (36, 37) between the flap 32 and the central panel 31 at both ends of the horizontal fold line 31 '. These grooves (36, 37) can facilitate the folding of the flap 32 towards the inside of the box 4 when reinforcing brackets 60 are positioned between the first body member 10 and the second body member 20. This also allows maintaining the reinforcing brackets 60. These grooves (36, 37) also make it possible to guarantee the verticality of angles placed at the front of the box along the folding lines (14 ', 15'). This also makes it easier to close the box when a cover is placed on the box. As illustrated in FIGS. 1, 2, 3, 4, 5, 6, 7, 10 and 13, the pallet box may comprise a retaining element 3 (for example mounted on the pallet 2 or on the bottom 50) able to retain or maintain the third body member 30 when it is positioned on the front face of the body 4.

Figure 12 shows the first body member 10 and the second body member 20 unfolded, the third body member positioned on the front of the body 4 and the body cover 40, a portion of which is tilted to the open position. The cover 40 comprises two central panels (41, 41 ') which articulate along the horizontal fold line 47. This has the effect of allowing the panel 41 to tilt outwards, the latter then falling back on the panel 41, then allowing the opening of a portion of the upper face of the lid 40 and thus partial access to the interior of the body 4. The horizontal fold line 47 may be for example half or third the length of the cover 40 in the longitudinal axis of the body 4 connecting the front face of the body 4 (open or closed side by the third body member 30 and the central panel 11 of the first body element 11 of the body 4 .

The lid 40 further comprises two central flaps (46, 46 ') which articulate respectively on the central panels (41, 41') along respectively the fold lines (48, 48 '). The lid 40 also comprises two lateral flaps (42, 43) which articulate on the central panel 41 along respectively fold lines (49a, 49a ').

The cover 40 further comprises two lateral flaps (42 ', 43') which articulate on the central panel 41 'along respectively fold lines (49b, 49b'). The central flap 46 articulates with the lateral flaps (42, 43) along respectively the fold lines (44, 45). The central flap 46 'articulates with the lateral flaps (42', 43 ') along respectively the fold lines (44', 45 ').

Figure 13 shows the first body member 10 and the second body member 20 unfolded, the first body member 10 being capped with its body cover 40, a portion is tilted in the open position.

As illustrated in Figure 13, the front face of the body 4 is open. In other words, the third body member 30 is not positioned on the body 4. Thus, the space created by the open portion of the lid 40 and the open space on the front face allow an operator to easily access the inside of the crate to store or remove merchandise.

Figure 14 describes a box 4 comprising a first body member 10 and a second body member 20 unfolded, the first body member 10 being capped with its body cover 40, a portion is tilted in the open position.
