• Such pouring elements are used in particular in gable packaging.
• These include also flat gable composite packages, which have long been known and are very often used for packaging of liquid foods such as milk, juice and the like.
• flat gable composite packages are cuboid and have a folded gable seam, which extends over the top of the package and is fastened by its ends to two opposite lateral surfaces of the pack.
• gable packs there are other types of gable packs.
• One type also consists of a composite material and has an upwardly extending gable in the upright position of the pack with two mutually inclined by the gable seam separate gable sections ("slanted gables") on.

• DE 24 17 387 A1 discloses a casting device for a container composed of two half-shells, wherein the casting device is inserted between the half-shells designed as sheet-metal or plate bodies and fastened thereto.
• the pouring device in addition to an opening neck with a cylindrical cross-section container side mounting member having a boat-shaped cross section, wherein the free cross section of the opening neck for flowing with flowable or pourable product is much smaller than the free cross section of the attachment member.

• the free channel cross sections of the pouring element taper from the product inlet opening to the product outlet opening, which is given only in the form of a plurality of small holes. This is to prevent leakage from the product, provided that there is no negative pressure by suction on the pouring element.

• the pouring element is welded to the inner bag, which in turn is glued to the pack from the inside.
• the pouring channel of the known pouring element tapers from the product inlet opening to the product outlet opening.
• a disadvantage of the generic pouring element is that, given a right-angled gable section, the maximum diameter of the pouring channel is determined by the length of the shorter sides of the gable section and the minimum required width of the flange. Thus, only relatively narrow pouring channels can be realized in which the pouring speed is reduced and the pouring is difficult. This applies in particular when using flat gable packages, since obliquely arranged gable sections have a larger area for the application of pouring elements.
• the invention By means of the invention, it is possible to provide, for a given packing, a pouring element having a pouring channel which has a much larger cross-sectional area for the outflow of product from the packing than is the case in the prior art.

It is further understood that with pouring elements with larger product inlet openings Compared to the product outlet openings, the product outlet openings represent the limiting bottleneck. Consequently, it is possible but less preferable to make the product inlet opening significantly larger than the product outlet opening. Ultimately, the size of the product outlet opening is not limited in many areas by the departure from consistently cylindrical pouring channels, so that you will run the product inlet and the product outlet opening in about the same size in the rule. The absolute size depends on the required or the possible for a given gable section.

Basically, however, there are certain constructional freedom in determining the production form of the pouring element.
• the flange and the adjacent portion of the packing can be made as two parallel layers bonded together with high bonding forces.
• the pouring element in the applicator mold has a product-inlet-side section, in which the channel cross-sections are more similar to a circle, the farther they are from the product inlet opening.
• a pouring channel is provided in the product inlet-side section, which gradually approaches a cylindrical channel, preferably beginning with the product inlet opening, in an outflow direction. This, preferably uniform, transition from a non-round, preferably oval, to a round channel cross section ultimately allows low pressure losses and a uniform flow.
