Definitions

  • the present invention relates to an automatic bottom case and its assembly method.
  • the automatic bottom boxes are known per se, boxes whose bottom flaps are partly glued to each other. These boxes are delivered flat and their implementation is very rapid since it suffices to open them so that their bottom is formed, any bonding means then being unnecessary.
  • Boxes-bottles are also known per se and consist of a box inside which is disposed a bag generally made of plastic.
  • This type of box is, for example, used for the packaging of powdery products or for the recovery of waste in hospitals. Their success lies in the fact that after filling the bag, it suffices to close it, for example by welding, before closing the box to very quickly obtain a practical and reliable packaging.
  • case-boxes are often provided with their plastic bag at the time of their use.
  • a second model of box-bottles has an automatic bottom.
  • there has never been an automatic bottom case containing the flat plastic bag because it is not possible to provide automatic means capable of inserting the plastic bag into the glued box and jointed presenting itself flat.
  • the plastic bag is a thin element and it is difficult to provide a clamp capable of grasping it without piercing it, all the more so because of the static electricity created between the bags, it is necessary to exercise a force large enough to take one from a pile.
  • Another difficulty which arises is that it is quite awkward to drag the bag towards the bottom of the box without the latter getting in the way or folding back on itself.
  • Such a case cannot be flattened for delivery so that one must deliver a set of flat cases and a set of bags, which obliges the buyer to have the means allowing the placement of the bags. in the crates.
  • the present invention tends to propose a box-bottom with automatic bottom of rapid production and which can be fully automated in order to be of an attractive cost and to be able to be delivered flat.
  • the invention provides a box-addition with automatic bottom, in corrugated cardboard, of the type in which a bag is held at the bottom of the box, characterized in that it comprises an additional plate on which the bag is fixed. , said additional plate being fixed to a flap of the automatic bottom of the box so that the box-addition is delivered flat and that when the box is opened, the automatic bottom is covered by the additional plate.
  • a cardboard cutout intended for the manufacture of an automatic bottom case generally consists of four portions.
  • Flaps 11, 21, 31, 41 are formed at the upper ends of said side faces and are intended for closing the top of the box after it has been filled.
  • Bottom flaps 12, 22, 32, 42 are also provided at the lower ends of the lateral faces for the formation of the bottom of the box. There are two large bottom flaps 12, 32 at the bottom of the wide side faces 10, 30 and two small bottom flaps 22, 42.
  • a lateral tab 13 is arranged along one of the lateral sides of the cutout, here along the wide lateral face 10.
  • the bottom flaps 12, 22, 32, 42 are, in a manner known per se, of generally trapezoidal shape in order to allow the automatic bottom to be deployed when the box is opened.
  • the different parts of the blank are separated from each other by creasing lines in order to allow them to be articulated and folded relative to one another during the formation of the box.
  • folding flaps 14, 34 extend two bottom flaps of the blank. These foldable flaps 14, 34 are arranged so as to be glued to the adjacent flaps, for the manufacture of the automatic bottom.
  • said folding flaps 14, 34 are arranged along the large bottom flaps 12, 32 secured to the wide side faces 10, 30 but they could also be arranged along the small bottom flaps 22, 42 secured to the side faces narrow 20, 40.
  • This additional plate 5 is a quadrilateral of the same shape and having the same length L and the same width 1 as the face of the bottom located inside the box after folding and joining it. In the figures, this additional plate is rectangular like the bottom of the box-body which must be manufactured using the cutout shown in Figure 1.
  • the bag 6 is a plastic bag whose opening has the same shape and dimensions as the opening of the box, its height is greater than the height of the box so that it is possible to close the end upper of said bag after filling.
  • This bag 6 is a flat bottom bag and side bellows.
  • the flat bottom of the bag is externally in the form of a trapezoid 61.
  • the end 60 of the bag is narrower than the rest of the bag and has the weld ensuring the closure of it.
  • Said bag 6 is fixed to the additional plate 5 for example by gluing on the face thereof visible in FIG. 2. This fixing tends to secure the bag 6 to the additional plate 5 and can be ensured by a simple point of glue in the bottom area 61 of the bag.
  • One way of making this attachment in a manner that is both safe and rapid consists in providing a slot 50 disposed in the middle part of the additional plate 5.
  • the end 60 of the bag 6 is then passed through this slot 50 in order to be disposed against the face of the additional plate 5 intended to be in abutment on the bottom of the box visible in FIG. 3.
  • the protruding end portion 60 can then be glued to the additional plate 5 in order to obtain a totally secure connection.
  • the bonding of the bottom of the bag is preferably carried out in addition to this joining in order to allow easy opening of said bag at the time of use.
  • This bonding is done on at least one area of the bottom 61.
  • This bonding area must extend over a large part between the slot 50 and the edge of the additional plate in order to concern a large part of the width of the half bottom of the bag. .
  • This bonding can be done over the entire hatched area A shown which generally corresponds to the trapezoid 61 by which the bag 6 is in contact with the additional plate 5.
  • the additional plate 5 must also be fixed to the automatic bottom of the box in order to form according to the invention a box-addition with an automatic bottom, the addition of which is perfectly in place when the box is opened.
  • a first method of manufacturing the box in addition to the invention consists in folding and gluing the cardboard blank in order to form the box and join it together as usual.
  • the plaque additional 5 being a corrugated cardboard plate having a certain mechanical resistance, this can be grasped by automatic means of the kind of those usually used in the cardboard industry.
  • the bag 6 being fixed as previously described on the additional plate 5, it is driven by any movement of the additional plate without risking being torn or folding back on itself. It is thus possible to slide the bag 6 precisely in the box and to ensure its perfect positioning at the bottom thereof.
  • the additional plate 5 carrying the bag 6 is positioned on one of the wide side faces, here the face 30, of the cardboard blank while the latter is placed flat before folding.
  • said additional plate 5 is disposed against the crease line separating the wide side face 30 of the large bottom flap 32 located in its extension and ensuring the articulation of said flap.
  • the additional plate 5 is placed with its face carrying the adhesive zone B on the top.
  • bottom flaps 12, 22, 32 and 42 are then folded against the side faces 10, 20, 30 and 40 in the usual manner. It can be noted that the large bottom flap 32 is then positioned on the additional plate 5 and in contact with the glue from zone B.
  • the foldable flaps 14 and 34 are then folded outwards and the faces thereof situated outside are glued as shown by the hatched areas C.
  • the tongue 13 is glued on its underside as shown by the dotted hatching shown in FIG. 4.
  • the folding and joining of the box are then carried out as usual by folding, according to the arrows F, the side face 10 on the side face 20 then the side face 40 on the side face 30; the tongue 13 is by this folding positioned under the edge of the lateral face 40 with the adhesive directed towards the latter.
  • the bonding of the different elements to each other is completed as usual, for example by pressing.
  • the box in addition according to the invention can be delivered flat, the implementation thereof for its use is done very quickly, simply by opening it. Indeed, the automatic bottom drives during its movement to get flat the additional plate 5 which is integral with it. When the opening of the box is finished, the automatic bottom is flat and is covered by the additional plate.
  • the implementation of the additional plate according to the invention makes it possible to propose a box-addition whose bottom is, on the inside, perfectly flat since it is covered by the additional plate whose shape and dimensions are provided in order to cover exactly said bottom.
  • This additional plate further strengthens the bottom of the box according to the invention.
  • the opening of the bag can be done very easily by the fact that its bottom is maintained at least in part on the additional plate.
  • the bag is made of plastic, but it can just as easily be made of paper or composite material.
  • the invention proposes a box-box with automatic bottom, ready to use .
