Definitions

  • the present invention relates to a plastic spout adapted to be fitted by means of a sealing technique between film walls of a flexible pouch, comprising a plastic body which forms a channel for dispensing a substance from the flexible pouch and/or feeding a substance to the flexible pouch.
  • the present invention aims to propose improved spouts or at least alternative designs.
  • the present invention provides a spout according to claim 1.
  • the two elongated wings extend between the film walls at either side of the central body part over a length of at least 8, preferably at least 12 millimetres. These "lengthy" wings serve to provide additional sealing surface between the film walls and spout. Also the wings provide a mechanical connection between the central body part and the adjacent areas of the upper end of the flexible pouch. This is in particular advantageous in an embodiment wherein the spout is provided with a screw cap, wherein the lengthy wings then provide the user with a "hold" for holding the spout while unscrewing or thightening the cap.
  • the inventive spout is efficient in view of the use of plastic material, which positively affects the injection moulding and cost price, when compared to prior art sealable plastic spouts.
  • Prior art spouts are known having a solid lower part to be sealed into the pouch which requires much plastic anyway.
  • More sophisticated prior art spouts, e.g. as proposed by the present applicant, have a lower part almost entirely formed by two sealing walls defining an opening between them which requires less plastic than the solid version.
  • the spout according to the present invention allows to "cover" a major part of said length via the two wings, which can contain a reduced amount of plastic material in comparison to a prior art spout having a wide N ⁇ eye- or boat shaped lower part" of the spout with no wings or with only short melting fins sealed between the film walls .
  • short meltable fins are present on diametrically opposed positions of the central body part of the spout. These meltable fins have a minimal length in a direction away from the central body part and when viewed from above an essentially triangular cross-section.
  • the short meltable fins are provided in order to fill the triangular area between the film walls at the position where the film walls diverge from one another near the spout and thus prevent leakage at this position.
  • These short fins neither provide a "hold” for the user of the pouch nor allow to arrive at the reduction of plastic material for the spout as explained above .
  • the lengthy wings also can contribute to an easier handling of the spouts prior to their sealing into a pouch, e.g. on vibratory feed equipment leading to the heat sealing device.
  • the sealing surfaces of the spout, including the sealing faces of the wings have a rough surface structure, which produces a good connection with the film walls of the flexible pouch.
  • the sealed connections perform very well if they are subjected to mechanical stress, for example in a drop test with a flexible pouch filled with liquid.
  • the sealing is preferably conducted using heated sealing jaws, but ultrasonic sealing or other suitable methods are also envisaged.
  • the first aspect of the invention further relates to a flexible pouch provided with such a spout.
  • the first aspect of the invention further relates to a method for manufacturing a flexible pouch with such a spout.
  • the first aspect of the invention further relates to the method of claim 28, wherein a flexible pouch is provided with a winged spout, which is sealed between film walls of the flexible pouch, and wherein the film walls are sealed directly to each other along the bottom edges of the wings. This is preferably done at the same time as sealing the spout into the pouch, in practice e.g. using the same heated sealing jaws which are provided with a zone for sealing the film walls against one another.
  • any barrier properties e.g. oxygen barrier, provided by the film walls (e.g. by a metallic layer in the film or foil) are now present in the areas below the wings, which enhances the barrier property of the entire flexible pouch.
  • a second aspect of the present invention relates to a spout
  • the design of the anti-nesting members with flange panels along the vertical sides of the central curved section allows for a high stability of these members. This also contributes to the stability of the entire spout, e.g. of the upper channel member, which protrudes from the pouch and is subjected to
  • a third aspect of the present invention relates to a spout according to claim 32.
  • the array of parallel ribs provides stability of the sealing walls, which allows for a thin design of the sealing walls themselves. This is advantageous for the heat sealing process.
  • the spacing of the ribs can be substantially uniform, (e.g. in the range from 3 to 5 millimetres apart from each other) , but non uniform spacing, e.g. a dense arrangement near the centre of the array and further apart near the ends of the array is also possible.
  • the ribs can have a tapering cross-section to allow for easier release from the mould.
  • a further aspect of the present invention provides for a spout, possibly a spout having no or less long wings than in claim 1, wherein the body of the spout is made of LLDPE or a blend including LLDPE, and wherein the film walls of the flexible pouch each contain a layer to be heat sealed to the sealing surfaces of the spout, possibly an inner layer of a multiple layer film, of LLDPE or a blend thereof, e.g. a blend with HDPE (High Density Polyethylene).
  • a polyolefin including Metalozene e.g. LLDPE including Metalozene is used as thermoplastic material for the spout.
  • LLDPE including Metalozene
  • Providing a combination of LLDPE elements (spout and inner layer of pouch) to be heat sealed against one another provides for excellent sealing.
  • the reduced rigidity of the spout is e.g. compensated for preferably by providing the wings, preferably wings having a reinforcement element, or the internal ribs on the sealing walls as disclosed herein.
  • a yet further aspect of the present invention provides for a spout to be sealed between the film walls of a pouch, wherein the body and an integral, user openable closure element of the spout are made of a first plastic material, e.g. HDPE or LLDPE, and the hinge

This is the preferred embodiment of the long winged spout 1 in combination with such a pouch 15, but a pouch could also be wider at the top than the width of the wing span of the wings.
  • the wings 10, 11 add stability to the upper part of the spouted pouch 15 and improve the adherence of the spout 1 onto the pouch 15. Also a user can easily grip the pouch when opening or closing the pouch with a user openable closure element, such as with a screw cap.

  • each wing 10 has an essentially triangular cross- section tapering from the top edge towards said bottom edge. This provides a stable design of the wing while at the same time allowing for improved sealing of the spout into the pouch (as will be discussed later) and allowing for a favourable behaviour under load (e.g. on impact testing of a filled pouch).

  • elongated reinforcement members 25 An additional effect provided by the elongated reinforcement members 25 is that - when the pouch is intended for a beverage or the like (drink-yoghurt) and the consumer is expected to drink directly from the pouch - the reinforcement members 25 cover the usually sharp top ends of the film walls so that the "mouth-feel" is improved.
  • a suitable design of the elongated reinforcement members 25, e.g. with a cross-section with a rounded top face, can add to this effect. Also one can envisage that said reinforcement member 25, or the upper or other layer thereof is moulded from a different

  • the figures 3a-d also show that the wings 10, 11 each have a top edge which slopes downward from the main body part towards the ends of the wings. This also contributes to the "mouth-feel" of the pouch.
  • the figures 3a-d show that the wings have a top edge which is straight, but other shapes, e.g. curved downward are also possible as shown in figures la-d. It is advantageous for the handling of the spout, e.g. in conveyor equipment that the lower edges of the sealing walls lie in a plane below the remote end of the wings.
  • each wing extends in longitudinal direction beyond the reinforcement member 25, e.g. by at least 2 millimetres, so that a reduced sideways stiffness of the wing is obtained at its far end. This is favourable in view of tensions in the film walls near the wing ends, e.g. when impact testing a filled pouch.
