Definitions

  • the present invention manufacturing procedure and box with pouring spout, consisting of a novel and original way of making a folding box, consisting of a die-cut sheet, preferably cardboard, folded on certain folding and gluing lines in certain areas of union, giving rise to a parallelepiped-shaped box with a pouring spout.
  • the present invention will be of special interest to the manufacturer and supplier of packaging and packaging material, and especially to the cardboard box and packaging sector.
  • the problem solved by the present invention lies in the difficulty of making the said pour spout in the folding boxes, made from a die-cut sheet, preferably cardboard, folded on certain folding lines.
  • the pouring spouts obtained in the latter way are formed by simply gluing their faces laterally, while in the invention presented, the spout is formed with the hook of the automatic bottom, when it collides with the edge of the box and fold it towards the inside of it.
  • the complexity of this procedure is that the area that generates the peak necessarily contains four parallel creasing lines, and that the assembly, when colliding with the automatic bottom hook, must always be bent by the same, precisely by the third creasing line marked there.
  • the areas represented by the part of the flap with which the pouring spout is formed respectively fall on their projection on the face of the box and are thus joined, since they have been previously glued. At this point the pouring spout is formed.
  • the box then continues on its way, and is folded laterally by the corresponding creases and finally by the crease and glued by the side gluing flap, thereby reaching the way it will be served to the customer.
  • the present invention is made up of a box-forming procedure, starting from die-cut plates and folded in a certain way, provided with pouring spouts, said procedure starting from a die-cut plate provided with a plurality of grooves that mark the different folds of the box, constituting the four lateral faces and the flaps with which the bottom and top cover are formed.
  • one of the flaps of the top cover of the box is prolonged by a silhouette that forms the pouring spout, consisting of an extension that after a first band, in which it is slightly narrowed by the ends, gives rise to two branches that end in the form of a protruding peak folded by a slit at the end of said branch, as well as on the face of the box, corresponding to the described extension of the flap of the upper cover of the box, there is a window, coinciding with the space defined between the ends of the referred ends of the branches, when the extension of the shape of the pouring spout is folded, by the line defined by the indentation that marks the end from the flap from which the shape of the pouring spout is born.
  • the construction procedure continues from the described die-cut sheet by folding the aforementioned shape of the pouring spout, by means of the gap between it and the flap from which the aforementioned extension is born, proceeding to glue on the corresponding face of the box, the two branches that end in the shape of a projecting peak and their respective ends.
  • the aforementioned window located on the face of the box, in which the extension of the flap of the upper cover of the box is located has a finger formed by an upper flange marked by a pre-cut groove, facilitating its breakage and allowing the window wall of the pouring spout to be pulled, causing the break by the pre-cut groove connecting the two branches that end in the form of a protruding spout and their respective endings.
  • the construction of the box is completed by closing the side walls by gluing a side flap and by closing the bottom and top by means of the bottom and cover flaps.
  • the present invention includes, in addition, some improvements that allow improving the described procedure, achieving thanks to the particular shape of the elements used, hook and set of rods, to correct the occasional lack of uniformity in guiding the boxes in the folding machine, facilitating the initial opening of the spout, as well as making it possible to make boxes with a spout even when the flap in which the spout is formed is wider than the spine of the box.
  • the present manufacturing procedure and box with pour spout consists of the fact that in the process of forming the box there is a set of a hook and a set of rods, of the "automatic bottom” type, specially designed for this box, having the particularity of the hook being made up of two rigid segments embedded in a spring, which gives it flexibility, facilitating its introduction through the central aisle even in those cases where the cut comes with a slight deviation.
  • the previous set of rods has the particularity that it does not limit itself to knocking down the flap that raises the hook, just as a conventional rod would do of those that follow the automatic bottom hook, but at the same time that knock down the flap, get the ears that make up the side walls of the pouring spout up, bending them ninety degrees along the crease line and then dropping them.
  • the purpose of this operation is to soften the crease so that the initial opening of the pour spout is facilitated, so that when progress is made in the assembly of the box, from the state illustrated in Figures 1 to 2 of the main patent, we do not We have limited to knocking down the flap where the pouring spout forms, but we have also softened the creases to facilitate their initial opening.
  • the previous set of rods is made up of a U-shaped outer element and a straight inner element, the inner element being able to be a wide one-piece plate or a double rod, its function being to hold down and hold the central part of the flap where the pouring spout is formed, that is, the part between the crease lines, once it has been laid down.
  • the U-rod has several zones, corresponding to different functions, it adopts a circular section shape with flattened ends and a slight V shape, its width being greater than that of the base of the flap that forms the pouring spout, in such a way that said flap is erect, when being lifted by the hook, so that the ends of the U-rod allow it to pass through the center without touching it, until the U narrows, brushes the flap and the grave, so that at that time the ends of the U have already been located below the ears, continuing towards the middle of its length, where the U-arms stop running parallel to the plane of the machine and begin to stand up, reaching their maximum height at the curved bottom of the U, this height being higher than the height of the ears, allowing the ears to fall at the end of the route, so that those of the pouring spout slide over the rod and are pushed upwards , while the central zone continues to be crushed by the central rod, making the ears bend 90 degrees.
  • This described operation of lifting the ears has the advantage that it allows one of them to be completely folded, rotating it 180 degrees with respect to the creasing line for the production of narrow-spine boxes with pouring spout, since when folding one of the ears it is not It is necessary that the development width of the flap where the pouring spout is formed has the small dimensions of the spine of the box.
  • To completely bend one of the ears simply place a strap at the point where the ear reaches its highest point (90 degrees) and loses contact with the U-rod. In this way, the strap prevents the ear Start the fall and bend it until it falls completely.
  • the flap that forms the pouring spout can be lifted by the automatic bottom hook when it is still at a certain distance from the tips of the long rods of the pre-bender assembly, placing an L-shaped strap that prevents the flap fall forward after being released by the hook. Otherwise we run the risk of the flap slipping underneath said rods, and breaking, causing a significant machine lock. But if the hook lifts the flap too soon, the flap falls forward again after being released from the hook, and in that case instead of being gently pushed by the friction of the outer rods, it is rammed frontally by the inner rods, which produces friction and marks and forces to work at a slower speed.
