Definitions

  • the invention relates to a pouring element for a composite package, in particular a beverage carton for liquid foodstuffs, with a base body having a fastening flange and a pouring tube, a cutting element arranged and guided in the pouring tube and a closure cap which can be connected to the base body, the cutting element being actuated over the at the first actuation Shaped cap first drive means and second drive means formed on the inner wall of the cutting element can be driven and wherein the movement of the cutting element follows different slopes and a composite package, in particular a beverage carton for liquid food, with a packing gable panel suitable for receiving a pouring element.
  • beverage cartons consist of various packaging materials, such as paper and plastics, which, when fully assembled and printed, form a packaging laminate.
  • the layer structure can vary depending on requirements, for example, an additional aluminum layer is inserted for aseptic filling goods in order to achieve a good barrier effect against gases and light.
  • the laminate is cut to the size of the packaging during its manufacture, and so-called packaging blank blanks (blanks) are formed in this way.
  • the packaging laminate is also delivered as a continuous material (rolled goods) and only cut later.
  • a packaging machine which is often referred to as a form / fill / seal machine based on its main functions.
  • Filled goods are mainly liquid foods such as drinks, soups or yoghurt. Stocked, pasty or lumpy products or the like are also conceivable.
  • Packs of the type mentioned are sometimes also provided with pouring elements. In addition to controlled pouring, these also generally enable the consumer to reclose. It is not uncommon and predominantly for aseptic use that a first opening function is provided for the pack. The previously sealed package is opened for the first time. This can be done for example by means of a pull-ring (“ring-pull”) or tab or also by means of a lancing and / or cutting device. Such puncturing and / or cutting devices are often designed as sleeve-like cutting elements (cutting rings) which are coupled to the screw cap, for example by means of drive means, so that the pack is cut open simultaneously by means of the rotary actuation of the screw cap.
  • ring-pull pull-ring
  • Such puncturing and / or cutting devices are often designed as sleeve-like cutting elements (cutting rings) which are coupled to the screw cap, for example by means of drive means, so that the pack is cut open simultaneously by means of the rotary actuation of the screw cap.
  • the international patent application dating back to the applicant WO 2007/113215 A1 shows for example a three-part pouring element.
  • the base body, screw cap and cutting sleeve are initially individually manufactured in the injection molding process and, when put together, result in a functional pouring element which can be permanently connected to a filled, described above, via a fastening flange on the base body.
  • the cutting element moves in the direction of an area of the composite package that is to be opened and separates it by means of a specially provided cutting edge.
  • the cutting element is driven by driver webs formed in the inner region of the cap, which act on corresponding hook-like projections on the cutting element and thus set it in rotation during the first opening process.
  • carrier webs are created in such a way that they can transmit torsionally stiff torsional forces due to their curved, concentric web shape, but can deflect radially inwards when they are closed again. So initiated Rotation movement is converted into a movement following a helical line via an external thread on the cutting element and an internal thread on the base body.
  • the thread pairing enables a relatively safe guidance of the components - which is always desired - but limits the kinematics of the cutting element to a constant feed. This can be disadvantageous since, in the case of packages of the type mentioned, a so-called "PE pulling" can occur during the separation process.
  • the polyethylene film stretches in length without separating, which results in a poor or even incomplete opening result, so that the product cannot be poured out in the required manner.
  • the second drive means are designed as an obliquely running rib enclosing an angle to the longitudinal direction of the cutting element, and in that the end face of the rib partially projects beyond its rib base and that the rib lies between the inner wall of the cutting element and the contact surface of the rib includes an acute fillet angle on its drive-side rib base. If the movement of the cutting element follows different gradients, a second drive means which runs obliquely to the longitudinal direction of the cutting element permits improved torque transmission from the closure cap to the cutting element. Ideally, the force acts exactly in the direction of movement of the cutting element.
  • the continuous rib has a solid strength.
  • the object on which the invention is based is also achieved by a composite packing, the packing gable panel having a local packing material weakening and such a pouring element being positioned and permanently connected in such a way that when the pouring element is actuated for the first time, the cutting element can be moved in the direction of the packing material weakening and can thus be severed, that the composite package is ready for emptying.
  • Pouring element and compound packaging must always be closely coordinated. Exact positioning on a packing gable panel provided for this purpose is of crucial importance.
  • the pouring element must remain connected to the composite package, on the other hand, the cutting element should dig into the packaging material weakening created for this purpose and then cut it open. This is the only way to fully open the package, which is then ready for emptying.
  • the angle ⁇ includes 40 ° to 50 °. With such an angular range, an optimal compromise is found even with different gradients of the cutting element movement.
  • the advantages of a rib and an improved drive do not have to be foregone.
  • the angle ⁇ includes 50 ° to 80 °. Tests have shown that such a region of the fillet angle offers a balanced solution between the management and drive functions.
  • the drive means sufficiently supports the cutting element guide, but does not hinder the drive.
  • the cutting element can be further driven via third drive means formed on the closure cap and fourth drive means formed on the cutting element.
  • the cutting element has fulfilled its function of opening the compound pack for the first time.
  • the first and second drive means are decoupled. If the closure cap is closed again after the product has been removed for the first time, the third drive means on the closure cap and the fourth drive means on the cutting element ensure that the cutting ring is pressed even further in the direction of the pack and that it is brought into its end position so that Decouple the drive means completely.
  • the fourth drive means are designed as an obliquely running second rib enclosing an angle ⁇ to the longitudinal direction, the angle ⁇ enclosing 5 ° to 25 °.
  • the second rib forms an obtuse angle ⁇ on the contact surface side, which has an angle of 100 ° to 130 °.
  • ⁇ an angle of 100 ° to 130 °.
  • a third rib which is transverse to the longitudinal direction is formed between the first rib and the second rib.
  • a horizontally extending rib also offers the advantage of a flat surface. Such may be desirable or necessary for the production by injection molding, since it can serve as a functional surface as a gating point and / or as a point of application of the ejection pins for demolding the part from the injection molding tool.
  • the first drive means are designed as first drive flanks, which ideally have an angular width on the contact surface side such that they form the complement angle with angle ⁇ .
  • the First drive means designed as thin-walled flanks, it is not only always possible to save material, but also allows the flanks to undergo slight elastic deformation.
  • Such a drive flank can - especially with a contact angle on the contact surface to the angle ⁇ - offer a particularly good drive and an additional supportive guidance of the cutting element.
  • the third drive means are also designed as a second drive flank, the closure cap can be manufactured particularly well.
  • the packaging material weakening is listed as an over-coated hole.
  • Such a special preparation of the packing material is particularly suitable for opening by means of a pouring element which is optimized in terms of drive and guidance, since the separation does not have to take place through the solid material of the composite packing.
  • the illustrated embodiment of a composite pack P according to the invention shows this as a beverage carton.
  • the composite pack P consists of a packing material that forms a packing laminate from a sequence of flatly joined materials: polymer layers are laminated on both sides of a cardboard carrier layer and an additional aluminum layer shields the product of the composite pack P from undesired environmental influences (light, oxygen).
  • the composite pack P provides a pack gable panel 1 in the head region, to which a pouring element A, which is also according to the invention, is applied and permanently attached.
  • a packaging material weakening region which is covered here by the pouring element A, is severed and the composite package P, which is thus ready for emptying, is opened for the first time.
  • this weakening area is designed as an over-coated hole which is formed during manufacture: a hole is punched out of the cardboard carrier layer so that local weakening occurs after it has been coated.
  • FIG Figure 2 shows the pouring element A according to the invention, the parts of which are individually assembled (assembled) in the injection molding process: a base body 2, a — here hidden — cutting element 3 (shown in FIG Figure 4 ) and a sealing cap 4.
  • the pouring element A which is now ready for use, is then applied to the composite package P via a fastening flange 5 and permanently connected by means of hot glue.
  • closure cap 4 If the closure cap 4 is actuated by the consumer for the first time, the unscrewing movement of the closure cap 4 is transferred to the cutting element 3 guided in the base body 2, which separates the composite pack P in the area of the weakening. The product can then be poured out through the opening created in this way.
  • the base body 2 which in addition to the mounting flange 5 also consists of a pouring tube 6.
  • the cutting element 3 is arranged in the pouring tube 6 and via first guide means 7 formed on the inner wall of the pouring tube and corresponding second guide means 8 formed on the cutting element 3 (see Figure 4 ) positively guided.
  • the first guide means 7 are formed by a circumferential web 9.
  • Figure 4 shows the cutting element 3 as a single part.
  • the second guide means 8 mentioned are realized as cam pairs 10 arranged over the circumference and molded onto the outer wall of the cutting element 3.
  • the pairs of cams 10 enclose the web 9 and thus form a forced guidance of the cutting element 3 in the pouring tube 6 of the base body 2.
  • the cutting element 3 then moves in the direction of the over-coated hole of the composite package P, pierces and / or cuts through it then by means of separating elements 11 formed at the end of the cutting element 3.
  • the cutting element 3 is driven by first drive means 12 formed on the closure cap 4 (see Figure 7 ), which act on ribs 14 formed on the inner wall of the cutting element 3 as second drive means 13 and thus set the cutting element 3 in the movement already described.
  • FIG. 5 the cutting element 3 mounted in the pouring tube 6 by the base body 2 is shown in the starting position.
  • the top view shows the fillet angle ⁇ enclosed in the foot region of a rib 14.
  • the end face 15 of the rib 14 projects beyond its foot on the drive side, so that the fillet angle ⁇ is an acute angle.
  • This acute fillet angle ⁇ supports the guidance of the cutting element 3.
  • the Figure 6 shows one of the ribs 14 in detail, which includes an angle ⁇ to the longitudinal direction of the cutting element 3. This enables an improved torque transmission from the closure cap 4 to the cutting element 3, the positive guidance of which in the pouring tube 6 of the base body 2 forces the cutting element 3 onto a movement path with different pitches.
  • third drive means 16 see Figure 7
  • fourth drive means 17 formed on the cutting element 3. These come into active contact when the closure cap 4 is reclosed and bring the cutting element 3 into its end position.
  • the fourth drive means 17 are formed as second ribs 18 and are inclined to the longitudinal direction of the cutting element 3 by an angle ⁇ and are furthermore by an obtuse angle ⁇ (in Figure 5 drawn), which also optimizes this drive part.
  • a third rib 19 forms a supplementary piece between rib 14 and second rib 18 and connects them in one piece.
  • first drive means 12 project as first drive flanks 20 from the cover into the interior of the closure cap 4.
  • first drive flanks 20 are of relatively thin-walled design and have the complement angle to the fillet angle ⁇ on the contact surface side.
  • Second drive flanks 21 are integrally connected to the first drive flanks 19 as third drive means 16.
  • the closure cap 4 is coupled to the cutting element 3 for the individual movements as a drive and the desired power and torque transmission can take place in a solid manner.
