Definitions

  • the object of the present invention is a spout closure for a thin-walled flexible package, generally called "pouch", usually used to contain liquid, dense or semi-dense food products.
  • Such packages are undergoing enormous growth and every year several hundred million pieces are produced. Particularly appreciated is their ease of use, mainly due to the ease of squeezing the packaging to get the product out .
  • the object of the present invention is to create a closure with a cap and a spout that satisfies the aforesaid requirements and at the same time overcomes the drawbacks mentioned with reference to the prior art.
  • FIG. 1 shows a closure for flexible packaging, according to an embodiment of the present invention
  • FIG. 5 schematically illustrates the partial circumferential extension (180°) of a closure membrane according to the present invention, in accordance with an embodiment of the invention
  • figure 6 shows a further embodiment of a closure according to the invention.
  • a closure according to an embodiment of the present invention intended for a flexible package with thin walls, usually called a pouch, is collectively indicated at 1.
  • the package comprises a pouch consisting of two flexible front walls made of single-layer or multi-layer film.
  • the closure 1 welded tightly therebetween.
  • the side edges and the lower edge may be welded together or welded to a bottom and/or side panels.
  • the closure 1 is one-piece, i.e. made of a single piece of plastic material, typically by means of injection molding.
  • the closure 1 comprises a spout portion 2 and a cap portion 4, joined to the spout portion 2.
  • the spout portion 2 extends predominantly along a rectilinear spout axis Z, between an inner end 6, intended to be placed inside the package pouch, and an opposite outer end 8, joined to the cap portion 4.
  • the spout portion 2 comprises, from the inner end 6 to the outer end 8, a connecting section 10, usually called a boat section, intended to be welded to the edges of the walls of the pouch.
  • Said connecting section 10 provides for two corrugated faces 12, 14, extending radially on an imaginary plane containing the spout axis Z, joining to the end in respective edges 16, 18.
  • the spout portion 2 further comprises, preferably, a flat base 20, lying substantially on an imaginary plane orthogonal to the spout axis Z, joined with the connecting section 10.
  • said base 20 has a circular shape.
  • the spout portion 2 further comprises a spout section 22, joined to the connecting section 10 or to the base 20, projecting axially therefrom.
  • said spout section 22 has a cylindrical outer surface, shaped by a succession of ridges and valleys having axial extension, for example with a square wave circumferential profile.
  • the spout portion 2 is penetrated internally by a usually circular cylindrical spout tube 30, coaxial to the spout axis Z between the inner end 6, where it defines an inlet opening 6a, and the outer end 8, where it defines an outlet opening 8a.
  • the cap portion 4 closes the outlet opening 8a and is joined to the outer end 8 of the spout portion 2 by means of a membrane 40 of the closure 1.
  • Said membrane 40 is preferably placed at an outer end 8 of the spout portion 2, lying substantially on a plane orthogonal to the spout axis Z and has a circular crown shape .
  • said membrane 40 extends radially internally relative to an edge of an outlet opening 8a defined by the extension of an imaginary surface on which lies an end segment of the side surface of the spout tube 30.
  • the membrane 40 is breakable by maneuvering the cap portion 4; in other words, it has structural features, such as axial height and radial thickness, so as to break due to maneuvering the cap portion 4, particularly by the bending thereof.
  • the membrane 40 has circumferentially a variable radial thickness Sr.
  • the thickness Sr has a first thickness Sri substantially constant for a first section of the circumferential extension and a second thickness Sr2 for a second part of the circumferential extension.
  • the second thickness Sr2 is greater than the first thickness Sri.
  • the first segment with thickness Sri extends for a large part of the circumferential extension of the membrane 40, while the second segment with thickness Sr2 extends for a limited predefined length, for example between 10% and 20% of the circumferential length or for an angular width between 30° and 60°.
  • the second segment of thickness Sr2 straddles the closure line between the mold and counter mold.
  • this allows the imperfection on the membrane due to the mold closing line to be masked.
  • the cap portion 4 preferably comprises a plug section 50 directly joined to the membrane 40, having a predefined axial extension and preferably consisting of an annular wall 52 that delimits a plug compartment 52 inside .
  • the annular wall 52 has a frusto-conical outer side surface.
  • said plug section 50 preferably comprises at least one sealing element, e.g. a pair of sealing elements 54, 56, protruding from the outer surface of the annular wall 52, axially spaced.
  • the plug section 50 is sealingly insertable into the spout tube 30 through the outlet opening 8a, so that, when the cap portion 4 is separated from the spout portion 2 for using the pouch, the pouch may be closed again by inserting the plug section 50 into the spout tube 30.
  • the cap portion 4 comprises moreover a gripping section 60 intended to be maneuvered by a user to remove the cap portion 4 from the spout portion 2.
  • the gripping section 60 comprises a lower base 62 that closes the plug compartment 52 and an upper base 64 placed at the top of the gripping section 60, spaced axially from the lower base 62.
  • said gripping section 60 comprises a plurality of transverse walls 66, substantially lying on imaginary planes parallel to the spout axis Z, spaced transversely, which axially join the lower base 62 and the upper base 64.
  • the gripping section 60 comprises the lower base 62 and a blade element 70 that juts axially from the lower base 62.
  • Said substantially flat blade element 70 lies on an imaginary plane passing through the spout axis 2 and has a first blade face 72 and a second blade face 74; at least one of either the first blade face 72 and the second blade face 74 faces the second segment with thickness Sr2.
  • said gripping section 60 comprises a plurality of ribs 76, for example parallel to each other and of different height, which join at least one between the first blade face 72 and the second blade face 74 to the lower base 62.
  • the closure according to the present invention overcomes the drawbacks of the prior art, as the rupture of the membrane is greatly facilitated along the first segment to then continue along the second segment .
  • the separation of the cap portion from the spout portion is therefore particularly simple, especially if the cap portion is bent in the correct direction.
  • the pouch provided with the closure according to the invention is also safer, because, in case the pouch accidentally falls, the thicker portion of the membrane allows the blow to be cushioned.
