EMBODIMENT OF THE INVENTION

(21) The following description relates to a packaging made of sheet-form card or corrugated card of the retail ready type or of the secondary packaging type; however, it should be noted that the packaging can naturally be intended for any other use and can be made of any other type of semi-rigid material without departing from the scope of the invention.

(22) In the following description, the same reference numbers are used in reference to packaging elements and/or cutouts that are identical or that occupy the same position.

(23) With reference to FIGS. 1 to 3, the packaging according to the invention comprises two elements, i.e. a first element forming the base 1 of the packaging and a second element forming the lid 2 of the packaging, said elements forming the base 1 and the lid 2 having a general L-shape, and being obtained from two identical cutouts 3. The base 1 and the lid 2 are secured by head-to-tail gluing to form a packaging that is substantially parallelepiped.

(24) Each cutout 3 forming respectively the base 1 and the lid 2 of the packaging comprises two main flaps, a first main flap 4 forming the bottom of the packaging and respectively the top of the packaging, and a second main flap 5 forming the side walls of the packaging, said main flaps 4 and 5 being connected by a first fold line 6. The packaging also comprises a set of lateral tabs 7 and 8 respectively, arranged on either side of said main flaps 4 and 5 respectively, and connected to said main flaps 4 and 5 by second fold lines 9 perpendicular to the first fold line 6. The first main flap 4 is of rectangular shape and the four corners thereof are chamfered, thereby forming chamfered corners 10, and the second main flap 5 is of rectangular shape, the long side of which is shorter than the long side of the first main flap 4.

(25) Furthermore, the lateral tabs 7 of the first main flap 4 have a length that is longer than the long side of said first flap 4, between two chamfered corners. In this specific embodiment example, the lateral tabs 7 of the first main flap 4 have a width that is shorter than the length of the second main flap 5, more specifically the lateral tabs 7 of the first main flap 4 have a width that is substantially equal to the length of the chamfered corners 10 of the first main flap 4, so that the products are visible on the longitudinal sides of the packaging. Moreover, the lateral tabs 7 of the first main flap 4 protrude from the chamfered corners 10 towards the second main flap 5 and each lateral tab 7 of the first main flap 4 comprises a third fold line 11, parallel to the first fold line 6 and extending in the part protruding from the chamfered corner 10, at the junction between the longitudinal side of the first main flap 4 and the chamfered corner, to form a strip 12 intended to be secured by gluing, for example, on the inner face of the tabs 8 of the second main flap 5. The lateral tabs 7 of the first main flap 4 protrude from the chamfered corners 10 in the direction opposite that of the second main flap 5. Each lateral tab 7 of the first main flap 4 comprises two third fold lines 11 that extend in the part protruding from the chamfered corner 10 in the direction opposite that of the second main flap 5, the third fold lines 11 extending to the angles of the chamfered corners and the distance between the two fold lines 11 being equal to the length of the chamfered corner 10, to form attachments strips 13. These attachment strips 13 allow securing the lid 2 to the base 1 or inversely. To assemble the base 1 and the lid 2, which are positioned head to tail, the inner walls of the attachment strips 13 of the base 1 and of the lid 2 are glued to the outer walls of the second main flap 5 of the lid 2 and of the base 1 respectively.

(26) Moreover, said lateral tabs 8 of the second main flap 4 extend over the entire length of the long side of said second main flap 5, and said lateral tabs 8 have a width that is equal to the length of the chamfered corners 10 of the first main flap 4.

(27) To rigidify the packaging, each cutout 3 comprises second lateral tabs 14 connected to the first lateral tabs 8 of the second main flap 5 by second fold lines 9, the width of said second lateral tabs 14 being substantially equal to the width of the first lateral tabs 7 in this specific embodiment example. It should be noted that the second lateral tabs 14 can have any width, as long as it is inferior or equal to the length of the longitudinal sides of the first main flap 4, without departing from the scope of the invention.

(28) Furthermore, the first main flap 4 of each cutout 3 is ended by an attachment strip 15, substantially rectangular and extending between the two chamfered corners 10 of the end of said main flap, connected to said first main flap 4 by a fold line 6. The width of these attachment strips 15 is substantially equal to the width of the lateral tabs 7. To assemble the base 1 and the lid 2, which are positioned head to tail, the inner walls of the attachment strip 15 of the base 1 and of the lid 2 are glued to the outer walls of the second main flap 5 of the lid 2 and of the base 1 respectively.

(29) Naturally, said main flaps 4 and 5 can be connected by means of a secondary flap, not shown in the figures, said main flaps 4 and 5 and the secondary flap being connected by parallel fold lines, without departing from the scope of the invention.

(30) According to a first embodiment, and with reference to FIGS. 4 to 6, the packaging according to the invention comprises two elements, i.e. a first element forming the base 1 of the packaging and a second element forming the lid 2 of the packaging, said elements forming the base 1 and the lid 2 having a general L-shape, and being obtained from two identical cutouts 3 shown in FIG. 1.

(33) The lateral tabs 7, once they are folded perpendicular to the main flap 4, form longitudinal walls of the packaging and the lateral tabs 8, once they are folded perpendicular to the main flap 5, form the chamfered panels to produce an eight-panel packaging that features great mechanical resistance, in particular under vertical compression.

(34) In order the secure the lid 2 to the base 1 or inversely, the first main flap 4 of each cutout 3 is ended by an attachment strip 15, substantially rectangular and extending between the two chamfered corners 10 of the end of said main flap, connected to said first main flap 4 by a fold line 6. To assemble the base 1 and the lid 2, which are positioned head to tail, the inner walls of the attachment strip 15 of the base 1 and of the lid 2 are glued to the outer walls of the second main flap 5 of the lid 2 and of the base 1 respectively.

(35) According to a second embodiment, and with reference to FIGS. 7 to 9, as previously described the packaging comprises two elements, a first element forming the base 1 of the packaging and a second element forming the lid 2 of the packaging, said elements forming the base 1 and the lid 2 having a general L-shape, and being obtained from two identical cutouts 3 shown in FIG. 4. The base 1 and the lid are secured by head-to-tail gluing to form a packaging that is substantially parallelepiped.

(36) Each cutout 3 forming respectively the base 1 and the lid 2 of the packaging comprises two main flaps, a first main flap 4 forming the bottom of the packaging and the top of the packaging respectively, and a second main flap 5 forming the side walls of the packaging, said main flaps 4 and 5 being connected by a first fold line 6. The packaging also comprises a set of lateral tabs 7 and 8 respectively, arranged on either side of said main flaps 4 and 5 respectively, and connected to said main flaps 4 and 5 by second fold lines 9 perpendicular to the first fold line 6. The first main flap 4 is of rectangular shape and the four corners thereof are chamfered, thereby forming chamfered corners 10, and the second main flap 5 is of rectangular shape, the long side of which is shorter than the long side of the first main flap 4.

(37) Furthermore, the lateral tabs 7 of the first main flap 4 have a length that is longer than the long side of said first flap 4, between two chamfered corners. In this specific embodiment example, the lateral tabs 7 of the first main flap 4 have a width that is shorter than the length of the second main flap 5, more specifically the lateral tabs 7 of the first main flap 4 have a width that is substantially equal to the length of the chamfered corners 10 of the first main flap 4, so that the products are visible on the longitudinal sides of the packaging. Moreover, the lateral tabs 7 of the first main flap 4 protrude from the chamfered corners 10 towards the second main flap 5 and each lateral tab 7 of the first main flap 4 comprises a third fold line 11, parallel to the first fold line 6 and extending in the part protruding from the chamfered corner 10, at the junction between the longitudinal side of the first main flap 4 and the chamfered corner, to form a strip 12 intended to be secured by gluing, for example, on the inner face of the tabs 8 of the second main flap 5. The lateral tabs 8 of the second main flap 4 extend over the entire length of the long side of said second main flap 5, and said lateral tabs 8 have a width that is equal to the length of the chamfered corners 10 of the first main flap 4.

(38) The lateral tabs 7, once they are folded perpendicular to the main flap 4, form longitudinal walls of the packaging and the lateral tabs 8, once they are folded perpendicular to the main flap 5, form the chamfered panels to produce an eight-panel packaging that features great mechanical resistance, in particular under vertical compression.

(67) In order to secure the lid 2 to the base 1, the lateral sides of the lateral tabs 8 of the second main flap 5 of the base 1, opposite the first main flap 4 of the cutout 3 comprise a tenon 17, in the form of a rectangular strip, intended to be introduced in a mortise 18, in the form of an oblique slot, provided in the first main flap 4, at the level of the corners opposite the second main flap 5 of the cutout 3 forming the lid 2.

(68) Moreover, the cutout 3 forming the lid 2 comprises two oblong cavities 16, a first oblong cavity 16 provided in the first main flap 4, and a second oblong cavity 16 provided in the second main flap 5, said oblong cavities 16 extending symmetrically on either side of the first fold line 6 connecting the first main flap 4 to the second main flap 5 and symmetrically on either side of the longitudinal axis of symmetry of the cutout 3. These oblong cavities 16 advantageously form gripping handles.

(69) According to a seventh embodiment of the packaging according to the invention, and with reference to FIGS. 21 and 22, the packaging according to the invention comprises two elements, i.e. a first element forming the base 1 of the packaging and a second element forming the lid 2 of the packaging, said elements forming the base 1 and the lid 2 having a general L-shape, and being obtained from two identical cutouts 3. The base 1 and the lid 2 are secured by head-to-tail gluing to form a packaging that is substantially parallelepiped.

(70) The cutout 3 forming the base 1 and the lid 2 of the packaging comprises two main flaps, a first main flap 4 forming the bottom of the packaging and a second main flap 5 forming a side wall of the packaging, said main flaps 4 and 5 being connected by a first fold line 6. The packaging also comprises a set of lateral tabs 7 and 8 respectively, arranged on either side of said main flaps 4 and 5 respectively, and connected to said main flaps 4 and 5 by second fold lines 9 perpendicular to the first fold line 6. The first main flap 4 is of rectangular shape and the four corners thereof are chamfered, thereby forming chamfered corners 10, and the second main flap 5 is of rectangular shape, the long side of which is shorter than the long side of the first main flap 4.

(71) Furthermore, the lateral tabs 7 of the first main flap 4 have a length that is longer than the long side of said first flap 4, between two chamfered corners. In this specific embodiment example, the lateral tabs 7 of the first main flap 4 have a width that is shorter than the length of the second main flap 5, more specifically the lateral tabs 7 of the first main flap 4 have a width that is substantially equal to the length of the chamfered corners 10 of the first main flap 4, so that the products are visible on the longitudinal sides of the packaging. Moreover, the lateral tabs 7 of the first main flap 4 protrude from the chamfered corners 10 towards the second main flap 5 and each lateral tab 7 of the first main flap 4 comprises a third fold line 11, parallel to the first fold line 6 and extending in the part protruding from the chamfered corner 10, at the junction between the longitudinal side of the first main flap 4 and the chamfered corner, to form a strip 12 intended to be secured by gluing, for example, on the inner face of the tabs 8 of the second main flap 5.

Each lateral tab 7 of the first main flap 4 comprises two third fold lines 11 that extend in the part protruding from the chamfered corner 10 in the direction opposite that of the second main flap 5, the third fold lines 11 extending to the angles of the chamfered corners and the distance between the two fold lines 11 being equal to the length of the chamfered corner 10, to form attachments strips 13. To assemble the base 1 and the lid 2, which are positioned head to tail, the inner walls of the attachment strips 13 of the base 1 and of the lid 2 are glued to the outer walls of the second main flap 5 of the lid 2 and of the base 1 respectively.

(72) Moreover, said lateral tabs 8 of the second main flap 4 extend over the entire length of the long side of said second main flap 5, and said lateral tabs 8 have a width that is equal to the length of the chamfered corners 10 of the first main flap 4.

(73) To rigidify the packaging, the cutout 3 comprises second lateral tabs 14 connected to the first lateral tabs 8 of the second main flap 5 by second fold lines 9, the width of said second lateral tabs 14 being substantially equal to the width of the first lateral tabs 7 in this specific embodiment example.

(74) Furthermore, the first main flap 4 of the cutout 3 is ended by an attachment strip 15, substantially rectangular and extending between the two chamfered corners 10 of the end of said main flap, connected to said first main flap 4 by a fold line 6. The width of these attachment strips 15 is smaller than the width of the lateral tabs 7. To assemble the base 1 and the lid 2, which are positioned head to tail, the inner walls of the attachment strip 15 of the base 1 and of the lid 2 are glued to the outer walls of the second main flap 5 of the lid 2 and of the base 1 respectively.

(75) Naturally, the chamfered corners 10 of the cutouts 3 and 3 of the examples described above can be convex without departing from the scope of the invention.

(76) Various machines to form and fill the packaging boxes can be provided.

(77) A first device to form and fill the packaging boxes according to the invention comprises a first forming machine that forms the base of the packaging from first cutouts stored vertically or horizontally in a store by means of a lateral or vertical motion mandrel, said mandrel providing the L-shape to the base of the packaging, and a second forming machine that forms the lid of the packaging from second cutouts stored horizontally in a second store by means of a second vertical mandrel, said second vertical mandrel providing the L-shape to the lid of the packaging and maintaining the lid on the base during gluing operations.

(78) A second device comprises a first store of first cutouts arranged horizontally or vertically, a second store of second cutouts stored horizontally or vertically, the gluing means enabling to deposit spots or beads of glue, the glue being hot-melt adhesive or cold glue, on the first cutout, and a pressing device performing the gluing of the second cutout on the first cutout and comprising a vertical motion press for the forming of the packaging comprising the base and the lid previously glued to one another.

(79) A third device to form and fill packaging boxes according to the invention comprises a first forming machine that forms the base of the packaging from the first cutouts and a second forming machine that forms the lid of the packaging from the second cutouts, as described previously, with the reversal of the L-shaped cutout and a transfer parallel to the base. Between the two machines, an operator or a machine fills the base with products.

(80) A fourth device comprises a first multi-purpose forming machine that provides an L-shape to a first cutout after extraction from a store of cutouts, around a mandrel, to form the bases, the box packing means of the products, said box packing means being well known to the person skilled in the field and depending on the typology of the products, and a second forming machine that provides an L-shape to a second cutout after extraction from a store of cutouts, to form the lids that are subsequently glued on the bases, all of the above means being secured to a single frame.

(81) Thus, the process for manufacturing packaging according to the invention comprises at least the following steps: extraction of a first element constituting the packaging, called base, from a first store of cutouts; deposition of glue, be it hot-melt glue or cold glue, on predetermined zones of the base; extraction of a second cutout, called lid, from the first store or from a second store; placing said second cutout so that it overlaps with the glued zones of the first cutout; static or fly pressing of the two cutouts; and three-dimensional forming of said cutouts.

(82) In order to implement said process, the device for the manufacturing of a packaging according to the invention, with reference to FIG. 23, preferably comprises a frame 21, conventionally made of struts, crosspieces and stringers, as well as safety side panels. The device also comprises at one of the ends of the frame 21 two cutout stores 22, 23, arranged parallel and side-to-side, said stores 22, 23 having a shape, a volume and an arrangement (horizontal or inclined) that are suited to the storage of cutouts according to the invention. The device also comprises extraction-transfer means 24 made, for example, of an articulated arm rotating about a horizontal axis, driven by a motor for example, and the free end of which comprises suction cups with bellows pressing against the faces of the cardboard cutouts of the packaging stored in the stores 22, 23. Thus, the extraction arm 24 takes two cutouts laid flat, simultaneously from the two stores 22, 23, and then performs a horizontal and perfectly positive displacement (continuous guiding and support) of a cutout towards a first hot glue injection system 25. At the following fixed station of the machine, the glue-coated cutout receives the second cutout, which is superimposed in a grouping station 26 to press and glue the cardboard cutout serving as base to the cardboard cutout serving as lid. Said grouping station 26 comprises a superposition cart 27, a pressing actuator 28 and a depositing actuator 29 depositing the cutouts on the superposition cart 27. Subsequently, the entire cutout thereby formed is transferred in a positive manner, i.e. perfectly guided with respect to a fixed machine reference, towards a forming station 30 comprising a second hot glue injection system 31 performing a rational and non-polluting gluing of all the connecting lugs of the base of the cutouts. This second deposition of glue having been completed, the cutout is pressed in a forming cavity 32 specially adapted to the shape and size of the cardboard, the principle of the pressing operation ensuring perfect squareness of the packaging. Finally, a conventional extraction system evacuates the cutout from the cavity and sends it to an output conveyor 33.

(83) It should be noted that all of the motions are synchronised by mechanical or servo-driven devices that are well known to the person skilled in the field and that various self-setting and tool-changing devices will facilitate the flexibility of the formats to be treated, as is expected from such a system (packaging+machine).

(84) Finally, it is understood that the examples provided above only constitute specific examples of the invention and are in no way limiting in terms of the scope of application of the invention.
