Definitions

  • the invention relates to a resealable pouring element for cardboard/plastic composite packs, in particular beverage packs, with a base element having a circumferential fastening flange and an external thread, with opening means arranged inside the base element at least in the unopened state of the pouring element and a screw cap with an internal thread, underneath the screw cap an anchor ring is arranged which is non-rotatably connected to the base element and is freely rotatable radially around the base element and is connected to the base element in a tension-resistant manner in the axial direction, so that for secure connection of the screw cap to the base element even in the unscrewed state, the anchor ring is connected via a hinge element, the pivot axis of which is tangential to the base element Outer circumference of the screw cap is aligned, is articulated to the screw cap.
  • a pouring element is from the applicant DE 10 2006 016 113 B3 known.
  • the screw cap is moved over the cutting element protruding from the pouring element and, together with it, pressed (bounced) onto the base element.
  • a plate is integrally molded onto the screw cap and is connected to the screw cap via connecting bridges.
  • the plate has pins on its underside, which engage in corresponding recesses in the flange of the base element and are caulked from below after assembly. The connecting bridges break when the pouring element is opened for the first time, so that the screw cap is then only loosely attached to the pouring element and the composite pack.
  • the US 2012/0181281 A1 shows a pouring element in which the screw cap is connected in the unopened state via connecting bridges to a plate attached to the circumferential flange of the base element. When opened for the first time, the connecting bridges are separated so that the screw cap is no longer connected to the base element.
  • EP 1 124 734 B1 is a closure device for a PET bottle with a ring arranged under the screw cap, which is connected to the screw cap via a film hinge and prevents the screw cap from being pulled off even in the open state.
  • the US 5,215,204 A shows a closure cap for a bottle with a ring arranged under the screw cap, which is materially connected to the screw cap via two connecting bridges.
  • the ring and the bottle are designed in such a way that the ring cannot be removed from the bottle.
  • the screw cap for a conventional bottle.
  • the screw cap consists of one Screw lid and a ring connected via a film hinge.
  • the ring ensures that the screw cap is securely connected to the bottle in the axial direction.
  • a generic pouring element in which an anchor ring which is connected to it in a rotationally fixed manner is arranged below the screw lid.
  • the anchor ring and the screw cap are connected to one another via a connecting element, which has two elements in the middle that form a hinge axis.
  • a pouring element in which a closure cap is connected to the base element of the pouring element via an anchor ring connected to the closure cap, even in the open state.
  • the anchor ring is connected to the base element in such a way that it cannot move upwards in the axial direction when the pouring element is opened.
  • the present invention is based on the object of designing and developing a resealable pouring element for cardboard/plastic composite packs of the type mentioned in such a way that a connection of the screw cap to the pouring element is ensured even when unscrewed.
  • a tensile connection is provided between the screw cap and the pouring element, in which the screw cap cannot be detached from the pouring element in the axial direction with a force of at least 10 to 30 N, which is usually necessary for opening a commercially available screw cap for the first time.
  • a radial adjustment of the screw cap in the locked open position is particularly advantageous in order to allow pouring out to enable any direction of the pouring element, since composite packs are not essentially rotationally symmetrical like commercially available PET bottles or have a substantially square cross-section and can be poured equally well from every side. Furthermore, it is desirable that in the locked open position there is as much free space as possible in front of the pouring opening, despite the opening means that are often present in the screw cap of cardboard/plastic composite packages and are necessary for producing a pouring opening.
  • the opening means are designed such that when the composite pack is first opened when the screw cap is screwed on, a pouring opening is created within the pack by breaking open the composite material of the pack or a barrier layer located in the base element
  • Pouring element is created that the base element has an outwardly projecting and essentially circumferential collar on its outside, that the anchor ring has at its lower end a substantially circumferential web directed towards the base element, which is arranged below the collar in order to prevent the Anchor ring over the collar to prevent the collar from being arranged in the axial direction in the upper region of the anchor ring in the unopened state, so that when the screw cover is unscrewed, movement of the hinge element in the axial direction is possible until the web comes into contact with the collar, and that the pivot axis of the hinge element is arranged in the axial direction in the upper half of the base element when the screw cover is pivoted away.
  • the axially tensile connection of the screw cap to the base element ensures that the screw cap does not represent a loose plastic part even when the pouring element is open and that it cannot enter the environment as a loose plastic part.
  • the invention thus makes a valuable contribution to reducing environmental pollution.
  • the film hinges that are usually used to connect a screw cap to a base element often tear off after just a small number of opening processes and therefore cannot ensure a secure connection of a screw cap to its base element.
  • the special design of the hinge element ensures that the screw cap does not become detached from the rest of the base element even after the pouring element has been opened several times.
  • the anchor ring By providing a substantially circumferential web directed towards the base element at the lower end of the anchor ring, which is arranged below the collar, the anchor ring is reliably prevented from being pulled off over the collar.
  • At least either the collar or the web can also be interrupted at one or more points, provided that it is ensured that the anchor ring, with its web directed towards the base element, cannot slip over the collar provided on the base element.
  • the anchor ring including the hinge element can cover the greatest possible distance upwards when the screw cap is screwed on and pivoted open, so that the pivot axis of the hinge element is offset upwards.
  • a pivot axis arranged as high as possible is desirable in order to enable the largest possible opening angle of the screw cap for comfortable pouring despite the bottle neck that is not present on composite packs.
  • the anchor ring has a slot running in the circumferential direction, which separates the anchor ring in a section into upper parts and a lower part, the upper parts and the lower part being arranged at a distance from one another in the axial direction. It is advantageous if the slot is in the circumferential direction in the area of the hinge element is arranged.
  • the hinge element can be connected to the upper parts of the anchor ring in such a way that the end of the upper parts facing the hinge element is twisted after the screw cap has been swiveled open.
  • the hinge element is arranged centrally to the slot in the circumferential direction. This ensures that the two sides of the upper parts of the anchor ring are loaded evenly when the screw cap is swiveled open.
  • a preferred embodiment of the invention provides that the lower end of the hinge element, in the unopened state of the pouring element, projects downwards over the lower end of the upper parts of the anchor ring in the direction of the fastening flange. If the screw cap is swung open after it has been unscrewed, the hinge element folds over with its lower end in the direction of the slot, so that at an opening angle of 120° to 150° the screw cap is locked in its open position with respect to its swiveling open. In this state, the screw cap can no longer swing back without applying external force. This has the great advantage that the screw cap does not automatically swing back when pouring and does not come into contact with the product during the pouring process.
  • the screw cap can be freely rotated radially in its locked open position. This has the great advantage that the screw cap can be turned into a position desired by the user. In the locked position, a slight force must still be applied from the outside in order to enable rotation, since the fixation of the screw cap with respect to its swinging open creates an increased frictional resistance between the hinge element and the base element. However, the increased frictional resistance is also desirable so that the screw cap does not easily move in the direction of the pouring jet when pouring, caused by the gravitational force.
  • a further teaching of the invention provides that the hinge element is arranged above the lower third of the base element with respect to its pivot axis in the unopened state. Arranging the hinge element above the lower third ensures that the screw cap can achieve an open position with an opening angle of 120° to 150° before the screw cap hits the composite pack. Since composite packs typically do not have a bottle neck like PET bottles, the swing-open movement of the screw cap is significantly more limited than with PET bottles. In order to achieve a sufficiently large opening angle for a pleasant pouring process, it is desirable to arrange the hinge element as high as possible.
  • the pivot axis of the hinge element is arranged in the axial direction in the upper third of the base element when the screw cover is pivoted away.
  • the opening means comprise a cutting element arranged in the interior of the base element and at least one driver web arranged in the interior of the screw cap and connected to it in a form-fitting or material-locking manner, which is preferably attached as close as possible to the hinge element in the circumferential direction.
  • the hinge element can be locked in the external thread of the flange in order to keep the screw cap open.
  • the driving bar is also possible to arrange the driving bar as far away from the hinge element as possible in the circumferential direction. This is useful if the hinge elements should not be in the way when the screw cap is opened/tilted away. This enables clean opening/tilting away without the hinge element and the upper edge of the pouring spout getting caught.
  • a plurality of driver webs arranged evenly distributed over the circumference are provided.
  • This driving bar can at least partially protrude from the inside of the screw cap when swiveled open. It is therefore particularly important that a sufficiently large opening angle of the screw cap can be achieved.
  • the pouring element according to the invention preferably has at least one originality seal between the fastening flange and the anchor ring or the screw cap.
  • This can consist of a band, one end of which is firmly connected to the anchor ring and in which the other end is connected to the anchor ring by means of a predetermined breaking point in such a way that the predetermined breaking point of at least one mandrel element arranged on the fastening flange When the screw cap is unscrewed, it is broken open and the consumer is informed that the first opening has already taken place.
  • a further ring is arranged below the anchor ring, which is connected to the anchor ring via a plurality of material bridges and serves as a seal of originality.
  • the screw cap, the anchor ring and the additional ring that serves as a seal of authenticity are made in one piece.
  • the ring can only be rotated to a limited extent by blocking webs projecting inwards from the ring with locking elements arranged over the circumference of the base element, so that when the screw cap is unscrewed for the first time, it is detached from the anchor ring by tearing off the material bridges and remains in its position on the base element.
  • a further embodiment of the invention provides that the base element has an outwardly projecting and essentially circumferential collar on its outside, the clear inside diameter of the collar being smaller as the clear distance between the oppositely arranged webs of the ring.
  • a further advantageous teaching of the invention provides that the fastening flange of the pouring element is connected to the inside of the composite pack.
  • a corresponding composite pack has a material recess at the location of the later pouring opening.
  • the pouring element is guided through the interior of the composite pack, positioned in the area of the material recess and then connected to the inside of the composite pack.
  • the interior of the base element is closed on the pack side in the unopened state, so that the product in the composite pack cannot flow into the pouring element in the unopened state.
  • opening means include an opening element which is arranged in the interior of the base element in the unopened state and is materially connected to it, and at least one force transmission element which is arranged inside the screw cap and is materially connected to it.
  • the opening element is positively connected to the at least one force transmission element and is separated from the base element at predetermined breaking points when the pouring element is opened for the first time, triggered by the rotation of the at least one force transmission element, so that there is no longer a material connection between the base element and the opening element. From this point on, the opening element is only positively connected to the at least one force transmission element, so that it cannot get into the composite pack present under the pouring element. When swiveled open, the opening element can at least partially protrude from the interior of the screw cap. Corresponding opening means are already available JP 5857668 B2 known.
