Embodiment Construction

[0016]Accompanying drawing 1 has shown pouring spout lid with perspective view. In the drawings the cover 1 is located at the front and the bottom part 2 is located behind it. The bottom part 2 consists of a horizontal plate 3 on which an upwardly protruding overhang 11 having a flange 4 is molded. A pouring spout 5 is formed on the front side of the bottom part 2 (ie the side towards the rear in the figure) and has a wall 6 extending at an oblique angle relative to the disc 3 . The overhang 11 with the flange 4 rises from the side of the hinge at varying heights relative to the disk 3 , this elevation encompassing the entire area 7 , while the flange 4 in the front area 8 is parallel to the disk 3 alone extending horizontally, thereby forming the pouring spout. The flange 4 is thus higher than the other area 7 in the area 8 where the pouring spout 5 is located. The overhanging member 11 encloses an opening 9 in the height direction of the disc 3 , said opening area 9 is "O...

Abstract

The pouring spout seal for composite packagings, comprises a lower piece (2) and a lid piece (1), moulded thereto with a hinge, for opening and closing the seal. The lower piece (2) is welded to a composite packaging with the flat underside thereof and comprises a round enclosing projection (11) extending upwards to form a pouring spout. The internal inner side of the projection (11) is open. The lid piece (1) has a moulded piece (21) thereon, which, in the opened state, projects upwards to form a planar upper surface and in the closed state for the lid piece (1) has a positive fit in the internal opening (9) in the underside of the lower piece (2), surrounded by the projecting edge (11). Said planar upper surface either runs flush with the underside of the lower piece (2), or extends below the same by a maximum of 0.5mm. Said upper surface of the projection (21) is glued to the position of the composite packaging prepared by a punching or welded to the sealing film of a composite packaging which is exposed due to a punching. On pivoting the lid piece (1) open, the sealing film in the whole internal region of the lower piece (2) is cleanly torn out.

Description

technical field [0001] The present invention relates to a mouth seal for use on composite packs. It is mainly used in packaging with the shape of such composite packaging for liquids such as milk, juices, various soft drinks or common non-food items and made of foil. liquid. However, the seal can also be used on composite packs containing free-flowing goods such as granulated sugar, semolina or various chemicals. The foil is made of laminated material, eg paper or cardboard layers coated with a plastics material such as polyethylene, and / or aluminium. Typical volumes for such packages are between 20 cl and 2 liters and larger. An aperture is pierced at the point of the composite package where the opening of the seal will be welded, said aperture being adapted to the opening of the seal, which opening will then be used to seal the foil seal. Background technique [0002] Mouth seals made of plastic that will be welded to the composite package in this manner come in a vari...
