Definitions

  • the present invention relates to a flexible container for liquid provided with a self-sealing pouring nozzle, and a method for the manufacture thereof.
  • Flexible containers for holding a beverage or other liquid have several advantages over rigid containers, including: lower manufacturing cost, minimal material usage and low volume after use.
  • the containers once opened, and in the absence of a separate rigid spout, welded or glued to the flexible sheets of the container can not be easily closed and tend to let out liquid. The user is therefore forced to hold the container once opened, since it can not be placed on a table or other surface before having emptied it completely to avoid unintentional leaks.
  • the document US 5,411,178 proposes a container in which a self-sealing effect is created by a narrowing or other obstacle close to the mouthpiece, thus developing a strong resistance to the passage of the liquid.
  • the self-sealing effect strongly depends on the dimensions of the passage as well as the characteristics of the liquid, and in particular its surface tension.
  • a self-sealing solution is proposed by WO 2004/087526 .
  • This patent describes a flexible container comprising two sheets of a flexible material, superimposed and assembled by a weld seam or bonding to define a sealed interior volume.
  • the mouthpiece of the container is outwardly projecting on an edge portion of the container and is connected to the interior volume of the container through an outlet channel.
  • the container contains one or more obstacles, formed by welding or bonding of the two walls, arranged in the interior volume near the channel leading to the mouthpiece, so as to limit the section of passage of the liquid between the interior volume and the channel of exit.
  • a surface portion comprising the tip and delimited by the obstacle and by folds oriented substantially transversely obstacles, arches and creates a valve that blocks the flow of liquid through the tip.
  • the user exerts pressure on the container in a direction substantially perpendicular to the plane of the obstruction weld, which has the effect of reducing the bending and bending and increasing the pressure of the liquid in the container, allowing the flow of liquid.
  • WO 2004/087526 is included for reference.
  • An object of the invention is therefore to provide a flexible container for self-sealing liquid that is economical and simple to manufacture.
  • a flexible container for liquid comprises two walls made of a flexible material bonded by a weld or gluing seam in order to define a sealed interior volume of said container, a pouring spout defined by said two walls having a nozzle arranged towards outside said container and an outlet channel connecting the nozzle to the interior volume of said container.
  • the flexible container of the present invention has a general diamond shape, and the spout is formed by welding or gluing in a corner with an acute angle.
  • the container comprises one or more obstacles formed by welding or gluing of the two walls and arranged in said interior volume essentially facing and close to the channel leading to the mouthpiece so as to limit the passage section of the liquid between the interior volume. and the output channel, leaving at least one narrowed passage free.
  • the inside angle of the corner with an acute angle can be between 60 ° and 85 °, preferably between 70 ° and 80 °.
  • the general shape of the diamond of the container according to the invention allows a corner of said container to act as a spout, while ensuring the function of self-sealing performance and reliable manner, without requiring cutting the walls for the formation of the spout.
  • the container according to the invention can thus be manufactured from very flexible polymer sheets commonly used for the manufacture of flexible containers, of rectangular shape and economic, without falling materials, using known methods of welding and separation of the containers. successive from sheets of continuous flexible material, in the production line.
  • the problem of cutting very flexible materials which, in view of their large plastic deformation, required precise mechanical cutting tools, or other cutting means incorporated in the non-standard production line, is especially avoided. manufacturing cost.
  • the container according to the invention can therefore be made from extruded polymer, commonly used, among others, in the food industry to contain liquid foods, for example polyethylene or polyvinyl chloride.
  • Objects of the invention are also achieved by a method of manufacturing self-sealing flexible containers according to claim 8.
  • the described method allows the simultaneous or continuous manufacture of several flexible containers for liquid.
  • These flexible containers can be made from a long sheet of flexible material.
  • the container according to the present invention has a very simple construction and manufacture, without requiring a cutting of the flexible walls around the spout to form the spout. It is therefore possible to use very flexible and economical materials for the manufacture of the container. On the other hand, it reduces the amount of material used to a minimum, which has a positive impact on the ecological balance.
  • a container 1 according to one embodiment of the invention comprises two walls of flexible material 15,16, interconnected by a weld or a bonding assembly 2 defining the periphery of the container 1.
  • the two walls of the container are advantageously formed from a sheet of flexible material folded on itself to compose the two walls. Otherwise, the two walls may be formed by two sheets of flexible material.
  • the weld bead 2 also limits a spout 3 disposed in a corner of the container with an acute angle.
  • the pouring spout is made of the same sheet of flexible material as the sheet constituting the container 1.
  • the spout comprises a nozzle 4 disposed towards the outside of the container and an outlet channel 5 opening into the flexible container 1
  • the pouring spout 3 may further comprise a rupture primer 20, making it possible to detach a portion thereof, thus opening the mouthpiece 4, respectively the channel 5.
  • the flexible material may be, for example, a polymer material, for example a plastic, such as a thermally deformable plastic, including for example polyethylene, polypropylene, polyvinyl chloride and polyester polymers or a mixture of polymers.
  • a low cost material for example a coextruded material, can be used.
  • the inside angle ⁇ of the corner of the container with an acute angle shown in Figure 2 can be between 30 ° and 98 °, preferably between 60 ° and 85 °, for example between 70 ° and 80 °, preferably about 75 °.
  • the acute angle of the container provides a pouring spout with an effective self-sealing function of a very simple construction and manufacture, without the need for cutting the flexible walls for the formation of the spout.
  • the container comprises a self-sealing tip as shown in Figures 1 to 4.
  • the two walls 15, 16, are welded or glued together inside the flexible container 1, close to the place where the channel 5 opens into the flexible container, so as to form an obstacle 6 arranged opposite the output channel.
  • the welded obstacle 6 is of elongated shape and extends between two ends which overlap the contour weld 2 on either side of the outlet channel 5, leaving two passages 8,8 'free in the direction of the channel 5. length of the overlap is relatively small compared to the total length of the contour weld 2, preferably less than 10%.
  • the elongated obstacle extends substantially parallel to the portions of the contour weld 2 on either side of the outlet channel, and approximately perpendicular to the general direction of the channel.
  • the large central part of the two walls 15 and 16 forming the container 1 differs and inflates by a not shown filling nozzle and closed permanently after filling, as seen in Figure 3 .
  • the folds 7 and 7 ', as well as the generally elongate obstacle 6, approximately along the dashed line of the nip 10 shown in FIG. 1, with the bead section 2 extending between the fold lines 7, 7' form a portion of surface that tends to curl (arch), as shown in Figure 3.
  • the bending of the area between the folds 7,7 'including the spout, has the effect of pressing the two flexible sheets in this against each other and thus to form a valve which blocks the flow of liquid through the passages 8, 8 'and through the orifice of the nozzle 4.
  • the crushing of the container in the direction F H substantially perpendicular to the weld plane of the obstacle has the effect of reducing the bending and the folds 7.7 ', while increasing the pressure of the liquid in the container which half-opens the lips flexible sheets at the entrance of passages 8,8 'to allow the flow of liquid.
  • a crushing force F H is applied approximately to side sections of the welding bead, accompanied by the increase of the pressure inside the container, a tensile force F T and a rotation torque F R act on the cord portion near the tip which tends to flatten, that is to say, to reduce the bending of the spout area, between the folds 7,7 '.
  • the general shape of the diamond of the container with the aforementioned internal angle ⁇ of the corner with acute angle makes it possible to optimize the tensile force and the torque created by crushing the container in the direction F h substantially perpendicular to the plane of the weld the obstacle 6, thus facilitating the flow of liquid through the tip 4.
  • the position of the tip in a corner with an acute angle of a rhombus shape allows the crash by the user of a part central longitudinally opposed welds of the container and to create an effective opening of the channel, allowing the easy flow of the liquid contained in the container.
  • a particular flexible package may also contain any kind of liquid, without considering here the chemical compatibility of the liquid with the material constituting the container.
  • the embodiment of the flexible container shown and described comprises an obstacle 6 defining two narrowed passages 8 and 8 '.
  • the welded obstacle 6 ' is arranged facing the endpiece as in the preceding embodiments, except that this obstacle is in two parts and is provided with of a central passage 12.
  • the central passage 12 arranged in the welded obstacle makes it possible to increase the flow of the liquid in the passage of the mouthpiece, when the user exerts pressure on the container in a direction substantially perpendicular to the plane of the obstacle weld.
  • the figures show a container 1 consisting of a single sheet of flexible material folded on itself on a straight edge.
  • the container 1 shown is provided with a weld seam along its four edges to form the interior volume of the container; it is understood that the weld along the straight edge can be omitted.
  • the container may consist of two sheets of flexible material interconnected by an assembly line in the form of gluing or welding.
  • a plurality of containers 1 can be manufactured simultaneously or continuously from a long sheet of flexible material.
  • Figure 5 shows a series of containers 1 made from a sheet of flexible material.
  • the containers are formed by folding on itself a sheet of flexible material to form the two walls 15, 16 of the containers.
  • the sheet of folded flexible material is then welded, for example by thermal welding, in order to define the border of the container around the interior volume, the pouring container with a mouthpiece and an outlet channel connecting the mouthpiece to the interior volume of the container and the obstacle.
  • the containers can be separated from each other by a simple cut, for example by thermal cutting. The welding and cutting steps can also be performed simultaneously.
