Description

[0001] The invention relates to a dispensing element for a composite packaging, in particular for a beverage carton for liquid foods, comprising: a base body comprising a fixing flange and a dispensing tube with a central geometric axis, a cutting element arranged and movably guided in the dispensing tube, first guide means formed in the dispensing tube and second guide means formed in the cutting element, wherein the first and second guide means cooperate correspondingly, wherein the first guide means are a rib arranged in the inner wall of the dispensing tube, wherein the rib can be divided into three approximately identical circumferential sections, wherein each of these circumferential sections comprises a high-level section for the initial position of the cutting element, a low-level section for the final position of the cutting element, and an intermediate-level section for the predominantly rotational movement of the cutting element, wherein each high-level section is connected to an intermediate-level section by a first transition section, and wherein each level section The intermediate section is connected to a low-level section by a second transition section. [0002] The invention also relates to a composite packaging with such a pouring element. [0003] In the field of packaging technology, composite packaging has long been part of the prior art. Thus, beverage cartons, for example, consist of various packaging materials, such as paper and plastics, which, when joined together on their solid surface and printed, form a packaging laminate. The layer structure can vary depending on the requirements, so that, for example, for aseptic contents, a barrier layer is additionally incorporated to obtain a good barrier effect against gases and light, for example, a barrier layer made of aluminum, polyamide (PA), or ethylene vinyl alcohol (EVOH). Often – but not always – the laminate is also cut to the size of the packaging during its production, and in this way, so-called pre-cut packaging pieces (raw blocks) are formed. Alternatively, the packaging laminate is also supplied as an endless material (laminated products) and only then cut to the right size. [0004] The forming and filling of the packaging and the closing of the latter to produce a container occur in a packaging machine, which, due to its main functions, is also frequently called a forming/filling/sealing machine. The typical contents are mainly liquid foods, such as drinks, soups or yogurt. Thickened, pasty or lumpy products or similar are also conceivable. [0005] The packaging of the type mentioned above is sometimes also provided with dispensing elements. In addition to allowing controlled dispensing, they, as a rule, also offer the possibility of resealing. Not infrequently, and especially with aseptic use, a first-opening function is also provided for the packaging. In this case, the previously gas-tight packaging is opened for the first time. This can occur, for example, by means of a ring puller or a pull tab, or also by means of a piercing and/or cutting device. Such piercing and/or cutting devices are frequently formed as sleeve-shaped cutting elements (e.g., cutting rings), which are coupled, for example, to the screw cap by means of actuating means, so that, by means of the rotational actuation of the screw cap, the packaging is simultaneously cut. [0006] For example, European Patents No. EP 3 464 089 B1 and No. EP 3 464 090 B1 disclose three-part pouring elements. Although these pouring elements have many advantages, it has been found that under certain circumstances (in particular, with smaller pouring elements), these pouring elements are unable to consistently cut and remove the layers of packaging material completely from the pouring tube. [0007] In this context, the objective of the invention is to improve the opening performance of the dispensing element. [0008] This objective is achieved with a pouring element, according to the preamble of claim 1, wherein each intermediate level section extends around the central geometric axis at an extension angle of at least 35°. [0009] The invention relates to a pouring element for a composite packaging, in particular for a liquid food beverage carton. The pouring element comprises a base body with a fixing flange and a pouring tube with a central geometric axis. The fixing flange can be attached to a package and the pouring tube serves to pour the contents of the package through the pouring tube. The pouring element also comprises a cutting element that is movably arranged and guided in the pouring tube. The cutting element can be formed as a circular cutting ring. Furthermore, the pouring element comprises first guiding means that are formed in the pouring tube, and second guiding means that are formed in the cutting element, in which the first and second guiding means cooperate correspondingly. The first guiding means is a rib that is arranged on the inner wall of the pouring tube. The
