Embodiment Construction

[0029] figure 1 , the pouring element according to the invention is illustrated in an exploded view. It basically consists of three distinct parts, namely a base body 1 , a hollow cylindrical opening element 2 and a screw cap 3 . The base body 1 is surrounded by a flange 4 and has an internal thread 5, which will be described in more detail later.

[0030] The opening element 2 has in its interior two diametrically opposite hook-shaped projections 7 , via which projections the rotational torque necessary for opening is transmitted from the screw cap 3 to the opening element 2 . The opening element 2 is equipped on the outer side with an external thread 8, which will also be described in more detail.

[0031] Now according to the invention, the external thread 8 is reduced on its lower section, which from figure 1 can be clearly seen in . The reduced area of ​​the external thread 8 is preferably on two diametrically opposite areas 8F of the opening element 2 .

Abstract

The invention relates to a reclosable pouring element consisting of a base body (1), which has a continuous flange (4), a stable inner thread (5) and an outer thread (6), an opening element (2) having at least one cutting edge (10) and a screw lid (3) that is configured as a threaded cap. The opening element (2) has a stable outer thread (8) and is situated in the interior of the base body (1). The length of the lower section of the outer thread (8) of the opening element (2) is reduced or interrupted, at least in one region (8F) and the length of the inner thread (5) of the base body (1) is reduced or interrupted at least in a corresponding region.

Description

technical field [0001] The invention relates to a reclosable pouring element for liquid food packed in a composite cardboard / plastic box, comprising: a base body surrounded by a flange and having internal and external threads of firm construction; having An opening element of at least one cutting edge or the like; and a screw cap formed as a screw cap, wherein the opening element has a firmly constructed external thread and is arranged in a base, and wherein the opening element is formed so that when the screw cap is used for the first time, it can Cut an opening in the box material below the pour-out element. Background technique [0002] Various configurations of reclosable pouring elements for liquid food products packed in cardboard / plastic composite packs are well known in practice. On the one hand, they are used for opening the pack for the first time and are mounted externally on an already filled and closed pack in an interesting configuration. For this purpose, th...
