• TH / bs 060180WO Furthermore, from WO 2004/000667 a three-part pouring element is known in which, however, the opening element is not moved in a screwing manner. The actual opening process happens here rather by a combination of a piercing with a rotary motion, so a superposition of an axial and a radial movement.
• the present invention has the object, the above-mentioned and more closely described above pouring element for cardboard / plastic composite packages and further, that while maintaining a simple three-part construction a particularly simple installation and good cohesion of the preassembled pouring element is achieved , Furthermore, a reliable penetration of the pouring spanning film over the first opening should be ensured.

• the invention has recognized that in this way the cutting element is always in a defined position: After removal from the injection mold a plurality of circumferentially distributed radial connecting bridges are provided for connection between the frame member and cutting element, which between the bottom of the cutting element and the upper edge run of the frame element and are destroyed only when nesting. Later, dropping out of the cutting element from the downwardly open frame member during transport or application to the composite package is reliably prevented. Even with the pouring element already applied to the composite packing, no damage to the underlying PE layer of the over-coated pouring opening can take place since the cutting element having the actual cutting elements is arranged inside the frame element so as to be protected.
• a simultaneous axial telescoping of the mounted on the unit of cutting element and frame element screw is sufficient to allow the final assembly of the applied to a composite package pouring.
• the frame member has at least one internal thread, which consists of two threaded portions, each extending over about a quarter of the circumference and having a slope corresponding to the pitch of the external thread of the cutting element.
• Thread pitch is achieved that when screwing the screw the cutting element moves very quickly with a cutting rotary motion (superimposed rotational and axial movement) in the over-coated pouring opening, so that there existing film is reliably destroyed and printed inside the pack, without completely demolish, because the cutting element does not perform a full turn.
• a further preferred embodiment of the invention provides that the external thread of the frame member is recountgangig and cooperates with the internal thread in the screw cap.
• the external thread in a preferred embodiment of the invention consists of a plurality of individual with short interruptions spaced threaded portions.
• the frame element at its lower inner circumference on a circumferential and downwardly pointing lip. This is manufacturing technology when demolding the injection-molded component frame element / cutting element favorably and further serves the lip as a stop for the rotated in the frame member when opening cutting element.
• the cutting element has a plurality of circumferentially arranged radially outwardly directed projections, which cooperate with corresponding inner cam of the frame member to prevent unscrewing of the cutting element from the frame member. When screwing on the screw cap, they release the rotation of the cutting element only in one direction, allowing only one left turn.
• These projections can be formed either by the cams projecting radially on the outside of the cutting element and / or by respective horizontal extensions of the upper ends of the threaded sections. Particularly preferably, the cams and the threaded sections merge into one another.
• the cutting element has on its outer side a plurality circumferentially distributed and radially projecting cams, which extend from the upper edge of the cutting element down and correspond in shape to the already described cam of the cutting element.
• the lower ends of all cams lie in a common, perpendicular to the vertical axis of the cutting element extending plane and thus serve for safe support on the lip at the inner end of the frame member.
• the screw cap on at least one internal power transmission element, which at the first unscrewing of the screw cap on arranged in the interior of the cutting element projecting cam the
• Such a power transmission element is preferably designed trapezoidal and concentric to the screw cap bent and facilitates the assembly process, the orientation of the screw with respect to the cutting element.
• a pouring element produced by the method according to the invention preferably has a tamper-evident seal.
• This can be formed by an integrally molded with the screw cap and radially projecting from this flat element, which is firmly connected to the flange of the frame member, wherein the element is connected to at least one destructible material bridge with the screw cap.
• TH / bs 060180WO 2 shows a frame element and a one-piece with this injection-molded cutting element before final assembly in a perspective view
• a pouring element according to the invention is shown in longitudinal section, consisting of a frame element 1, a single piece with the frame member 1 injection molded cutting element 2 and a screw 3.
• the frame member 1 has in its cylindrical Hauptkorper an external thread 4 and a peripheral flange. 5 for attachment to a composite package (not shown).
• Inside the frame member 1 can be seen a threaded portion 6A.
• the assembly of frame member 1 and cutting element in Fig. 2 is shown in perspective. There is a corresponding with the threaded portion 6A threaded portion 7A of an external thread 7 of the cutting element 2 can be seen, both threaded portions 6A and 7A have the same, compared to the external thread 4 very steep slope.
• an inwardly projecting cam 9 can be seen at the upper edge of the frame member 1, which serves as a stop for the cutting element 2, which will be discussed in more detail below.
• Fig. 2 shows that the cutting element has at its upper periphery a plurality of cams, which
• cams 10 are each disposed above the threaded portions 7A and 7B.
• cams 11 and 12 of which only the front of the opposite pairs can be seen, are in the illustrated and so far preferred exemplary embodiment with a horizontal extension 7D of the threaded portion 7B einstuckig connected.
• a horizontal extension 7C of the threaded portion 7A can be seen.
• teeth 13 of the cutting element 2 are also clearly visible. These teeth 13 have in the preferred and illustrated embodiment sharp edges.
• radially inwardly projecting cams 14 can be seen, as can be seen particularly clearly from FIG.
• the frame member 1 is connected to the cutting element 2 via connecting bridges 15, as also apparent from Fig. 2.
• the screw cap 3 has an internal thread 16 corresponding to the pitch of the external thread 4 of the frame element 1 and an internal, essentially trapezoidal, and concentrically with the screw cap extending force transmission element 17.
• the force transmission element 17 causes the cutting element is rotated by means of the inwardly projecting cam 14 at the first opening of the spout along the threaded portions 6 and 7 and thus penetrates axially into the package interior.
• Fig. 4 now shows the finished mounted pouring element in vertical section, wherein the axial movement of the applied screw cap 3 and the cutting element 2 has been moved axially into the interior of the frame member 1, without moving in rotation. It can be seen clearly that the tips of the teeth 13 are also arranged at a distance from the lower edge of the frame element 1.
• Fig. 5 the finished mounted pouring is reproduced in perspective again for clarity. It can be seen here that the pouring element according to the invention also has a seal of originality:
• a plate 18 is injection-molded onto the screw cap 3 in one piece, which plate is pressed against the screw cap 3 via connecting bridges 19
• TH / bs 060180WO is in connection, as clearly apparent from Fig. 5.
• the plate 18 has on its underside in the present case, two pins 20 which engage in corresponding recesses 22 (Fig. 2) of the flange 5 from the frame member 1, which are caulked for firm connection from below.
