Definitions

  • the invention relates to a pouring element for a composite pack, comprising a base body with a pouring tube and a peripheral fastening flange, a hollow-cylindrical cutting element arranged concentrically in the pouring tube and guided movably, and a reclosable screw cap, the cutting element being able to be driven by the screw cap for opening the composite pack for the first time and wherein at least two guide ribs formed on the inside of the pouring tube interact in a corresponding manner with transmission means formed on the outside of the cutting element in such a way that an opening path is described with an upstream at least predominantly axial piercing path and followed by a pure rotational path around the longitudinal axis of the pouring tube, with the cutting element being arranged in such a way that that it can be guided along the opening path.
  • pouring elements are applied to the gables of composite packs for simplified handling when pouring and for the possibility of reclosing them.
  • the hollow-cylindrical cutting element opens the previously gas-tight package for the first time and thus forms a pouring opening, with the screw cap enabling the now opened composite package to be closed again.
  • These pouring elements are usually applied by separate machines, either with the help of hot-melt adhesives or by welding the base body to the outer plastic cover layer. In both variants, the all-round fastening flange is used for this application process.
  • the exact layer structure of the composite material can vary depending on the requirements, but it consists at least of a carrier layer made of cardboard and cover layers made of plastic.
  • a barrier layer e.g. aluminium, polyamide or ethylene-vinyl alcohol copolymer
  • Such composite packs are therefore also referred to as cardboard/plastic composite packs.
  • Such a composite pack is normally made in one of two types of packaging machines.
  • a continuous web of sterilized composite material is formed into a tube and sealed, after which it is filled with the contents, also sterilized, and sealed and cut at regular intervals across it.
  • the resulting "packaging cushions" are then formed into parallelepiped packs along the pre-folded edges.
  • the sealing seam created during cross-sealing in the gable area is usually referred to as the gable seam.
  • the other variant uses blanks made of composite material, which are first formed into pack casings by sealing the longitudinal seam and then formed into pack bodies open on one side on mandrels, then sterilized, filled and finally sealed and finally formed.
  • the composite pack is usually adjusted accordingly.
  • the pouring element with its cutting element could be made strong enough to easily cut through the entire composite material.
  • this is mostly uninteresting for cost reasons.
  • so-called weakening lines are introduced into the outer layers of the composite material, which, tailored to the geometry and size of the cutting element to be used, enable easier separation.
  • the weakened area can be designed as a so-called "overcoated hole".
  • the first option has the disadvantage that open carton edges arise, which come into direct contact with the filling when pouring out. This can lead to cardboard fibers in the product as well as changes in the taste of the same. Therefore, an overplated hole is usually the preferred solution.
  • An overcoated hole like this one in the EP 2 528 731 A1 as described in more detail by the applicant, is formed during the manufacture of the composite material.
  • a hole is punched out in the cardboard carrier layer, so that after it has been coated with the plastic cover layers, a local weakening occurs in the composite material. So it's made up of all the usual layers of composite material without going through that Punching out the missing cardboard carrier layer:
  • the plastic cover layers if necessary a barrier layer and, if required, further laminating and adhesion promoter layers.
  • the EP 1 088 765 A1 describes a generic pouring element.
  • Base body with a pouring tube and a surrounding mounting flange, screw cap and cutting element together form a pouring element which, when actuated for the first time, severs the overcoated hole over a large area and forces the uncut part of the same to the side to create a pouring opening.
  • the movement of the cutting element is guided via a thread on its outside in the pouring tube of the base body and is driven by the screw cap. Since the cutting element is guided via a thread, the assembly - the assembly of the individual components - proves to be complex due to the undercuts of the thread and production in the injection molding process is only possible with restrictions in terms of material selection and/or tool design.
  • this form of cutting element guidance therefore offers insufficient safety.
  • the cutting element can deviate from the intended path or, before application to a package, the mounted cutting element could shift in various ways, jam or even fall out completely. During the opening process, various incorrect manipulations can also lead to the cutting element jamming.
  • the present invention is based on the object of designing and developing the pouring element mentioned at the outset and previously described in more detail in such a way that the disadvantages described are overcome.
  • Safety should be increased: On the one hand, the known and desired opening behavior should be guaranteed when handling the pouring element, but the function should also be maintained in any case even if the consumer misbehaves. In particular, it must be prevented that the cutting element becomes detached and falls out of the base element, so that it could possibly be swallowed.
  • pouring element having the features of the preamble of patent claim 1 in that the pouring tube has at least two first safety elements which, together with the at least two guide ribs, are used to guide the transmission means of the cutting element on both sides along the piercing and/or or rotation distance of the opening path are configured.
  • first safety elements can additionally secure the movement of the cutting element during the opening process, which may prevent the cutting element from being displaced or tilted in an undesired manner.
  • the transmission means can no longer move freely on one side in the base body, for example turning back the screw cap of a closure that has not yet been fully opened can at least not bring the cutting element into undesired positions. Even if excessive force is applied to the pouring element, the cutting element with the transmission means remains in the guide.
  • each guide rib encloses an angle ( ⁇ ) of 90° to 120°, preferably 90°, to a plane which is perpendicular to the longitudinal axis of the pouring tube.
  • a rib is an elongate shaped reinforcing part of a component construction, in this case such ribs project from the inner wall of the pouring spout of the body to guide the cutting element. The angle is then also measured on the side edge of the rib that guides the corresponding guide means of the cutting element.
  • the special case of an angle of 90° corresponds exactly to the explanations from the already mentioned EP 1 513 732 B1 the applicant and also the exemplary embodiment detailed here.
  • the first guide means are designed as at least two transmission ribs, which extend in a first section in the circumferential direction.
  • An extension in the circumferential direction - that is, in the horizontal when the pack and the pouring element are arranged flat - of these transmission ribs serves for safe steering during the pure rotation, or on the pure rotation section of the opening path.
  • the end face of each of these transmission ribs runs along the corresponding guide rib.
  • each transmission rib has a height, measured in the axial direction, which is 90 to 99% of the clear distance, measured in the axial direction, between the guide rib and the corresponding first security element.
  • the distances should be kept small, with a certain amount of play always being necessary so that the transmission ribs guided on both sides do not block or get caught in an undesirable manner.
  • the at least two transmission ribs should have a second section at their front end in the direction of rotation, which extends at an angle of 90° to 120°, preferably 90°, from the first section towards the circumferential fastening flange.
  • the angle is measured at the leading edge of the rib portion and the special case of 90° corresponds to the embodiment already mentioned. Since the however, if the second section has to dip between the guide rib and the first security element during the piercing process, the flanks of the second section preferably converge at an acute angle from top to bottom. In such a case, the mean angle measurement of the leading and trailing edges can also be used to compensate for this alignment.
  • the second sections each have a width, measured in the circumferential direction, which is 90 to 99% of the clear distance, measured in the circumferential direction, between the guide rib and the corresponding first security element.
  • the at least two first security elements are designed as axially arranged longitudinal ribs and, after the opening process has taken place, each longitudinal rib is surrounded laterally by two of the at least two horizontal transmission ribs of the cutting element.
  • These longitudinal ribs serve several purposes. On the one hand, they allow the second section to be guided on both sides over a longer piercing path.
  • the next auxiliary element in the direction of rotation - in the case of two, simply the other - offers a stop point for the transmission means or the second sections thereof after they have completed the rotation in the circumferential direction. The end point of this rotation is of course also defined in other designs, but axially arranged longitudinal ribs offer a more stable position.
  • the rotational section of the opening path is additionally followed by an axial section.
  • This last movement along the additional axial distance which ends in the so-called parking position, is normally only carried out when the closure, which has already been opened, is closed again.
  • the force transmission elements between the screw cap and the cutting element move away from one another during the initial opening due to their axially opposite directions of movement.
  • these power transmission elements can no longer fulfill their function and the cutting element remains in place for the time being this position.
  • the force-transmitting elements slide past the force-transmitting elements of the cutting element, evading inward direction, and this movement is only carried out and the cutting element brought into the parking position when it is opened again.
  • the pack is already completely open before this axial distance is walked.
  • three transmission ribs as transmission means, three corresponding guide ribs and three first safety elements are formed in each case distributed uniformly in the circumferential direction.
  • the number of the respective elements also defines the maximum angle of rotation of the horizontal rotary movement of the cutting element. This maximum angle of rotation is defined as (360° / number of elements), in this case 120°. This angle of rotation, in turn, affects how the teeth at the lower edge of the cutting element must be circumferentially positioned in order for the overcoated hole to be cut cleanly.
  • At least one second security element is attached in a region of the pouring tube remote from the peripheral attachment flange.
  • the transmission means which would otherwise only be placed on the at least two guide ribs, are also held from above and thus on both sides. This prevents the cutting element from falling out or jamming at various stages of production and use. Otherwise, for example, a cutting element could fall out again during assembly, so that a pack would ultimately be delivered with a base element and screw cap but without a cutting element.
  • second safety elements it could happen that the cutting element tilts in the assembly position and then blocks and/or comes to rest loosely in the base element during the initial opening.
  • such a second security element could also be positioned in such a way that the transmission means rest on it. This would still guarantee that the cutting element is centered and thereby secured. At least a single second security element is required to close the cutting element stabilize, but in practice the number of guide ribs, transmission means and security elements are usually identical.
  • a further teaching of the invention provides that the at least one second security element is chamfered at least on a side facing away from the circumferential fastening flange.
  • This upper side of the second safety element is not important for the function and it is therefore designed for simplified assembly in such a way that the cutting element can be inserted from above with the least possible resistance without having to incorporate a rotation of the cutting element into the assembly process.
  • this teaching of the invention enables the cutting element to still pass the element on the opening path without disproportionately increasing the opening forces.
  • such a second security element should not make up more than approximately 80% of the extension in the radial direction of the at least two guide ribs.
  • the opening path is preceded by an additional, purely rotational path, with the cutting element being arranged in such a way that it is also securely held in an original holding position by the second safety element.
  • a pouring element 1 according to the invention is shown in a perspective view from the outside. Here it is in the assembly position, i.e. in the same way as it is applied to a composite pack.
  • the individual components of the pouring element 1 are in the exploded view of 2 to see better.
  • a screw cap 2 is attached to a base body 4 together with a cutting element 3 in the form of a hollow cylinder.
  • the lower part of the screw cap 2 is designed as an anchor ring 5 which, after the opening process, serves to reliably prevent the screw cap 2 from being removed from the base body 4 or from a composite pack provided with it.
  • the screw cap 2 and the anchor ring 5 are connected to one another in an articulated manner.
  • This joint is formed by two superimposed weakened zones 6, both of which span only part of the entire circumference of the screw cap 2 and are usually formed by several successive cuts.
  • an indicator element 7 also serves as an originality seal, which is designed in such a way that it is already visibly broken before the cutting element 3 has damaged the overcoated hole during the piercing process, as in FIGS Figure 6A and 7A can be seen. This functionality cannot always be guaranteed with weakening zones 6 alone.
  • Force transmission elements 9 can also be seen, which act on force transfer elements 10 of the cutting element 3 in order to drive the cutting element 3 during the screwing movement of the screw cap 2 and to move it along the intended path.
  • the effective surface of the force transmission elements 9 closes an angle of between 30° and 60° cap surface. This angle of action makes it possible to drive the cutting element 3 in the piercing as well as the rotary movement.
  • a further shoulder serves to better guide the cutting element 3 in the course of the horizontal rotary movement.
  • the force transfer elements 10 have two corresponding surfaces in order to optimally absorb the force of the rotary movement of the screw cap 2 .
  • Two of three circumferentially extending transmission ribs 11 are visible at the upper edge of the cutting element 3, each of which has a second section 12 at the end leading in the direction of rotation, which is formed at an angle of 90° to the transmission ribs 11.
  • the lower edge of the cutting element 3 is equipped with a large number of cutting teeth 13--twelve in this exemplary embodiment.
  • the cutting teeth 13 have a shape with tips optimized for the piercing process and a cutting edge located at the front in the direction of rotation, which cut open the overcoated hole during the pure rotational movement.
  • the teeth are arranged one after the other in such a way that a notch is created between each two cutting teeth 13, which is able to cut through possible stretched polyethylene threads that could result from "PE pulling".
  • the angular range that is not equipped with cutting teeth 13 must be smaller than the maximum angle of rotation of the cutting element 3 so that the coated hole can first be cut cleanly and then the uncut area can also be easily pushed to the side.
  • a residual emptying gap 14 is also formed in this free area, which ensures that after the opening process has been completed and especially after the initial reclosure, at least this point of the pouring channel is free of elements protruding into the composite pack. This makes it possible for the last residues of the contents to be emptied out of the composite pack through this gap.
  • a pouring tube 15 and at the lower edge of it a peripheral fastening flange 16 which together form the base body 4 .
  • the peripheral attachment flange 16 is either wetted with an adhesive or welded directly to the outermost plastic layer of the composite package.
  • guide ribs 17 and first and second safety elements 18 and 19 can be seen on the inner wall of the pouring tube.
  • threads of an external thread 20 can again be seen, which serve as a counterpart to the internal thread 8 of the screw cap 2 .
  • centering elements 21 are visible on the lower edge of the base body 4, which on the one hand additionally center the cutting element 3, but also form a closure towards the overcoated hole. Also visible is the longitudinal axis A of the pouring tube 15 and the hollow-cylindrical cutting element 3, which are arranged concentrically. The longitudinal axis A thus also functions as the axis of rotation for the rotation of the cutting element 3 during the opening process.
  • Figure 3A is the pouring element 1 in the same perspective view from below as in FIG 2 seen in the assembled mounting position.
  • the tooth tips of the cutting teeth 13 of the cutting element 3 maintain sufficient distance to the lower surface of the peripheral fastening flange 16 and thus also to the overcoated hole when the pouring element has been applied to a composite pack. This in turn prevents inadvertent premature damage to the overplated hole.
  • Figure 3B shows the same situation seen from below, with the force transmission elements 9 of the screw cap 2 being hidden in order to ensure a better overview.
  • the rear ends of the horizontal transmission ribs 11 can be seen here on both sides of the guide ribs 17, since these rest on them and are therefore covered in this view.
  • Figures 4A to 4C show the pouring element at the start of the piercing movement, for which screw cap 2 and cutting element 3 must have already turned a little in order to leave their original stable position. This turning movement is marked with arrows in all partial figures.
  • Figure 4B shows how the cutting element 3 has rotated and the transmission ribs 11 are now in contact with the guide elements 17 .
  • Figure 4C It can also be seen how a second section 12 of the transmission ribs 11 can already be guided over a surface area along guide elements 17 before the first security elements 18 engage.
  • Figure 4A and 4B the longitudinal axis A of the pouring tube 15 of the pouring element 1 is also shown, the piercing movements along this axis and the rotary movements around this axis being carried out as part of the cutting process.
  • FIGS 6A to 6C show the pouring element 1 at the end of the piercing process and thus at the transition to the horizontal rotary movement.
  • the cutting teeth 13 are now protruding so far that all cutting edges act on the overcoated hole (not shown here). Since the overcoated hole stretches as an elastic layer when it is pierced, there are usually still scraps of polyethylene between the different teeth in this position, which are then only severed during the horizontal rotary movement. Further, between the foremost and rearmost of the cutting teeth 13 is a continuous overcoated hole integrity to which the remainder of the overcoated hole remains attached so that it can be pushed aside by the cutting element 3 . It can also be seen that the force transmission elements 9 now interact with the force transmission elements 10 with their lowermost and vertically shaped section. Since from this point only the screw cap 2 - via the flat unscrewing movement - moves in the axial direction, this vertically shaped section is rather small compared to the rest of the power transmission elements 9.
  • FIG. 6C the second function of the first auxiliary elements 18 can now be seen, since the transmission ribs 11 are clearly guided on both sides during the rotary movement.
  • the cutting element 3 was only supported from below by the forces acting on the overcoated hole. The increased safety through this support function is shown here very clearly. It can also be seen how the height Y1 measured in the axial direction may be at most as great as the clear distance between the guide rib 17 and the first security element 18 measured in the axial direction, which is shown here as Y2, so that the horizontal rotary movement can be carried out.
  • the lengths Y1 and Y2 are chosen so that the horizontal transmission ribs 11 are performed closely and still enough play is available to a clean and to allow easy gliding. Shown in dashed lines, it is particularly easy to see on the second section 12 how the transmission ribs 11 of the cutting element 3 progress in the course of the rotary movement.
  • the screw cap 2 is now further unscrewed for different lengths of time. It has been shown that a total rotation of 360° to 450° is considered optimal by the consumer. In this embodiment, the total rotation of the screw cap 2 amounts to 410°, with the cutting element being driven only about 120° thereof, so that a completely open overcoated hole can be guaranteed before the screw cap 2 detaches from the body 4.
  • ribs should not go unmentioned in this context.
  • a rib is an elongate shaped reinforcing part of a component construction, here such ribs projecting, for example, from the inner wall of the pouring spout of the body in order to guide the cutting element.
  • most of the functions of this invention can also be fulfilled by, for example, at least two smaller elements protruding from the wall of the pouring spout, which can have different shapes and are arranged linearly. In other words, this would be a rib in which gaps have been introduced.
