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 at least in the unopened state of the pouring element inside the base element and a screw cap with internal thread, the opening means so are designed that when the composite pack is first opened when unscrewing the screw cap by breaking open the
• a generic pouring element is known from DE 10 2006016 113 B3, which goes back to the applicant.
• the screw cap is moved over the cutting element protruding from the pouring element and pressed (bounced) onto the base element together with it.
• a plate is molded onto the screw cap in one piece 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.
• No. 5,215,204 A shows a closure cap for a bottle with a ring which is arranged under the screw cap and which is firmly 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 pulled off the bottle.
• a screw cap for a conventional bottle is known from WO 2009/048273 A2.
• the screw cap consists of a screw cap and a ring attached via a film hinge.
• the ring ensures that the screw cap is connected to the bottle with tensile strength in the axial direction.
• the present invention is based on the object of designing and developing a reclosable pouring element for cardboard / plastic composite packs of the type mentioned at the outset so that the screw cap can be connected to the screw cap even when it is unscrewed
• the pouring element is ensured.
• a tensile connection between the screw cap and pouring element is provided, 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 enable pouring from any direction of the pouring element, since composite packs are not essentially rotationally symmetrical like commercially available PET bottles or have an essentially square cross-section and from each side can be poured out equally well. It is also desirable that, in the locked open position, there is as much free space as possible in front of the pouring opening in spite of the opening means often present in the screw cap in the case of cardboard / plastic composite packs, which are necessary for producing a pouring opening.
• this object is achieved in that underneath the screw cap there is an anchor ring which is connected to it in a rotationally fixed manner and which can be rotated radially freely around the base element and is connected to the base element with tensile strength in the axial direction and for secure connection of the screw cap to the base element, even in the unscrewed state, the anchor ring is articulated to the screw cap via a hinge element whose pivot axis is oriented tangentially to the outer circumference of the screw cap.
• Basic element ensures that the screw cap is also in the open state the pouring element is not a loose plastic part and this cannot get into the environment as a loose plastic part.
• the invention thus makes a valuable contribution to reducing environmental pollution.
• the film hinges usually used to connect a screw cap to a base element often tear off after only a small number of opening processes and therefore cannot guarantee 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 has a circumferentially extending slot which separates the anchor ring in one 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 arranged in the circumferential direction in the area of the hinge element.
• the hinge element can thus 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 pivoted open.
• the hinge element is arranged in the circumferential direction in the center of the slot. This ensures that the two sides of the upper parts of the anchor ring are evenly loaded when the screw cap is pivoted open.
• a preferred embodiment of the invention provides that the lower end of the hinge element in the unopened state of the pouring element protrudes over the lower end of the upper parts of the anchor ring downward in the direction of the fastening flange. If the screw cap is pivoted open after it has been unscrewed, the lower end of the hinge element folds in Direction of the slot around, so that at an opening angle of 120 ° to 150 °, the screw cap is locked in its open position with respect to its pivoting open. In this state, the screw cap can no longer pivot back without applying a force from the outside. This has the great advantage that the screw cap does not automatically pivot 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, however, a slight external force must be applied in order to enable rotation, since the fixing of the screw cap with respect to its pivoting 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 move easily in the direction of the pouring jet during pouring, caused by the force of gravity.
• Another teaching of the invention provides that the hinge element with respect to its pivot axis in the unopened state above the lower third of the
• Base element is arranged.
• the arrangement of the hinge element above the lower third ensures that the screw cap can realize an open position with an opening angle of 120 ° to 150 ° before the screw cap hits the composite package. Since composite packs typically do not have a bottle neck as is the case with PET bottles, the pivoting movement of the screw cap is much more limited than with PET bottles. However, in order to achieve a sufficiently large opening angle for a pleasant pouring process, it is desirable to arrange the hinge element as high up as possible.
• the base element has an outwardly protruding and essentially circumferential collar on its outside.
• 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. Also, at least either the collar or the web can be interrupted at one or more points, provided that it is ensured that the anchor ring with its web facing the base element cannot slip over the collar provided on the base element.
• the collar is arranged in the unopened state in the axial direction in the upper area of the anchor ring, so that when the screw cap is unscrewed, the hinge element can move in the axial direction until the web comes into contact with the collar.
• 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 screw cap to have the largest possible opening angle for easy pouring, despite the bottle neck not being present on composite packs.
• the pivot axis of the hinge element is arranged in the axial direction in the upper half of the base element, particularly preferably in the upper third of the base element.
• ribs ensure that the anchor ring always has a certain distance from the base element in the radial direction. As a result, the anchor ring is centered with respect to the base element in every condition.
• the opening means comprise a cutting element arranged inside the base element and at least one driving web arranged inside 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 external thread of the flange can be locked in order to keep the screw cap open.
• the driver web is also possible to arrange the driver web as far away as possible from the hinge element 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 a clean opening / tipping away without the hinge element and the upper edge of the pouring spout getting caught.
• a plurality of driver webs distributed evenly over the circumference is provided.
• this driver web can at least partially protrude from the interior of the screw cap. 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 tamper-evident 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 Unscrewing the screw cap is broken and thus indicates to the consumer 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 tamper-evident seal.
• the screw cap, the anchor ring and the further ring serving as a tamper-evident seal are manufactured in one piece.
• the ring is preferred by blocking inwardly protruding from the ring
• Bars with locking elements arranged over the circumference of the base element can only be rotated to a limited extent, so that when the screw cap is unscrewed for the first time it is released 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 protruding and essentially circumferential collar on its outside, the clear inside diameter of the collar being smaller as the clear distance between the opposing webs of the ring.
• Another 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 at the point of the later pouring opening
• opening means comprise an opening element arranged in the unopened state in the interior of the base element and cohesively connected to it, and at least one force transmission element which is arranged in the interior of the screw cap and is cohesively 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 any 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. In the pivoted-open state, the opening element can at least partially protrude from the interior of the screw cap. Corresponding opening means are already known per se from JP 5857668 B2.
