Definitions

• the packaging systems intended to condition and protect products are generally produced in a very simple manner from a sometimes decorated cardboard blank, comprising a bottom and a cover.
• the cardboard used which is relatively flexible, does not provide good resistance both to compression, at the side walls, and to crushing by stacking of the products, which poses problems of deterioration of the content or storage issues.
• closure of the box is generally carried out by bonding or even only embedding a tab of the cover, which does not ensure the locking and therefore the inviolability of the packaging, which inviolability is increasingly sought after, especially in large areas.
• the present invention relates to a locking box which can be used, but not exclusively, for the packaging of bottles, and making it possible to eliminate these drawbacks.
• a first object of the invention is to provide a lockable packaging box, having an inviolable character, access to the product can only be achieved by deterioration of the packaging.
• Another object is to provide packaging combining the calibration of the content and good resistance to compression.
• the locking box consists of a cardboard sheath and at least one attached shutter comprising, on its sides, lugs which cooperate with anchoring means, arranged at at least one of the ends of said sheath.
• the sheath is formed from a single blank of cardboard comprising, for example, four extended side walls, on at least one side forming an end, by the anchoring means in the form of locking tabs.
• these tabs are intended to be folded inwards to cooperate with the lugs of the shutter.
• the locking tabs have notches which cooperate with the lugs of the shutter in order to lock the assembly.
• the shutter intended to produce the bottom and / or the cover of the box consists of a core whose shape allows it to fit inside the end of the sheath, and a flat surface, forming a base, integral with the core and resting on the edge of the end of the sheath.
• the size of this flat surface corresponds at least to that of the sheath.
• the core of the shutter is hollowed out and the shape of this hollow is adapted to the content so as to achieve its setting.
• the lugs of the shutter have a hook shape, of triangular appearance.
• the invention makes it possible to obtain a packaging which effectively protects the products against any deterioration, thanks to the shutters conferring good resistance to packaging and ensuring correct and precise setting of the products.
• This type of box also saves on cardboard and ensures a permanent closure that can only be removed by deterioration.
• FIG. 1 is a perspective view of the box according to the invention provided with two shutters, one providing the bottom and the other the cover,
• FIG. 1 is a flat view of the cardboard blank
• FIG. 3 is a top view of the internal face of the shutter
• FIG. 4 is a sectional view of the shutter along 4-4
• the locking box 1 according to the invention is shown in Figure 1.
• It consists of a cardboard sheath 2, of square section, associated with two independent shutters 3 respectively constituting the bottom and the cover of the box.
• the sheath 2 is produced from a single blank of cardboard as shown in FIG. 2. It has four rectangular side walls 21, 22, 23, 24, separated by fold lines and each extended on each side by locking tabs 25.
• Each tab 25 has a width a substantially less than the width b of the side walls 21, 22, 23, 24; they are separated from their respective wall element by fold lines and they each have an orifice 26 of generally rectangular shape, disposed approximately at their central part.
• the free side of the side wall 24 is provided with an extension 27 in the form of a tongue, intended for the association, by gluing or stapling for example, of the wall elements 24 and 21, when the sheath 2 is being placed in volume. .
• Each end of the sleeve 2 is then provided with a set of four legs 25 each secured to a wall
• the orifices 26 and in particular their external edges 28, are intended to serve as anchoring means for a closure member 3, at each end of the sheath.
• FIGS 1, 3, 4 and 5 show one of the possible embodiments of the shutter 3.
• This shutter member 3 is identical for the bottom and the cover; it is preferably made of plastic material and consists of a core 31 of generally parallelepiped shape. It has dimensions such that it can just fit inside the ends of the sleeve 2.
• This core 31 is associated with a flat surface 32 forming a base and having dimensions greater than said core 31 so as to present a peripheral rim 33.
• Aembase 32 corresponds at least to that of the sleeve 2 and the flange 33 is intended to come to rest on the end edge 4 or 5 of the sleeve.
• the size of the planar surface 32 is substantially identical to that of the sleeve 2.
• the core 31 of the shutter 3 comprises a set of lugs 35, arranged laterally at the sides 34.
• the lugs 35 are arranged substantially at the level central flanks 34 and are intended to cooperate with the outer edges 28 of the holes 26 of the legs 25, to achieve, on each side, the locking of the box.
• the lugs 35 have the shape of a hook of triangular appearance in cross section, and they have an external side 36 parallel to the flange.
• peripheral 33 and a gently sloping side 37 connecting to the flanks 34.
• These lugs 35 extend over a little more than half the length of the flanks 34.
• the core 31 of the shutter is inserted into the end of the sleeve.
• the flared sides 37 of the lugs 35 push the upper parts of the lugs 25 towards the side walls of the sleeve, until the lugs 35 fully engage in the orifices 26.
• the tabs 25 return towards the flanks 34 of the shutter and they are housed between the peripheral rim 33 and the side 36 of the lugs, preventing any movement of the shutter member 3.
• the peripheral rim 33 is limited in its travel by the end edge 4 or 5 and the lug 35, in the opposite direction, by the edges 28 of the tabs 25.
• the distance separating the rim 33 from the side 36 must be very slightly greater than the distance separating the end edges 4 or 5 from the edges 28.
• a locked box is thus obtained, inviolable otherwise by deterioration.
• the internal face of the cores 31 may include recesses or reservations, intended on the one hand to save plastic material and on the other hand to ensure the positioning and wedging of the product in the packaging.
• recesses or reservations intended on the one hand to save plastic material and on the other hand to ensure the positioning and wedging of the product in the packaging.
• box l is intended to serve as packaging for a bottle 6.
• the identical shutters 3 In order to correctly calibrate and position the bottle 6 in the box, the identical shutters 3 have a recess 38, the bottom 39 of which is provided with a set of three studs 40.
• the square recess 38 has sides corresponding substantially to the diameter of the base of the bottle 6.
• the studs 40 of the shutter 3 constituting the bottom of
• the packaging fits in the lower reserve of the bottle.
• the three studs 40 of the shutter 3, constituting the cover of the box, are intended to be placed around the stopper or the neck of the bottle.
• the dimensions of the box are such that the two bottoms 39 of the shutters 3 just enclose the bottom and the. top of the bottle 6 in order to ensure its wedging in length and therefore the possibility of superimposing different packages, without risk of damage by crushing.
• the bottom of the shutters 3 will be shaped according to the nature of the product to be packaged.
• a single shutter can be used to produce, for example, the cover of the box, the bottom of this box being produced in a conventional manner, by extensions at the blank.
• Locking the shutters 3 on the sleeve 2 can be achieved by only three or even two lugs, the constituent parts of the box then being arranged in this direction.
• the shape of the sheath 2 and the shutters 3 can also be different: rectangular, polygonal or other.
