Patent ID: 8424728

Claim:
A two-part or multipart plastic closure ( 1 ) for fastening to a neck of a flexible bottle for dispensing thixotropic fluids, comprising a bottom part ( 2 ) with a circumference wall ( 3 ) and a top surface ( 4 ) into which at least one pouring opening ( 5 ) is formed; below the top surface ( 4 ) and spaced apart from the top surface ( 4 ) in an axial direction, a support surface ( 12 ) closes off a free axial passage from a container neck to the at least one pouring opening ( 5 ); the support surface ( 12 ) having at least one axially extending through opening ( 13 ), which is radially offset in relation to the at least one pouring opening ( 5 ); an underside of the top surface ( 4 ) having a formed-on annular retaining bead ( 10 ) or a retaining wall in which a separate disk ( 11 ) serving as the support surface ( 12 ) is secured by a form-locked and/or frictional nonpositive engagement; in a chamber ( 17 ) between the support surface ( 12 ) and the top surface ( 4 ) in both flow directions only one direction change from axial to radial and one subsequent direction change from radial to axial occurring and between the two direction changes a flow constriction ( 21 ) provided wherein the disk ( 11 ) has a central raised area smaller in diameter than a raised area ( 7 ) in the top surface ( 4 ) of the bottom part ( 2 ) and the central raised area of the disk having a central recess ( 15 ) around which the at least one axially extending through opening ( 13 ) in the central raised area is arranged and having a spout-shaped extension ( 14 ) extending into a region close to a level of the lower edge of the extension of the at least one pouring opening ( 5 ) to produce a flow passage free in a radial direction, but having a constriction ( 21 ).
