Closure for a bottle for correcting fluid
First Claim
1. In a closure for a bottle for correcting fluid, consisting of an insert of yieldable plastics material fitted into the bottle neck with a flange lying against the upper edge of the bottle neck and a tubular piece connected thereto, which comprises an upper, also internally cylindrical section adjoining the flange and a lower cylindrical section projecting freely into the inside of the bottle, and consisting of a brush part fitted into a closure cap, with a brush rod, in whose lower end brush hairs are inserted, and which comprises at its upper end a sealing flange cooperating with the flange of the insert, the improvement wherein the upper and lower cylindrical sections have at least approximately the same inside diameter, wherein at the lower end of the upper cylindrical section there are provided a plurality of tongues directed from the inner wall of the upper cylindrical section obliquely downwards to the axis (A) of the insert, between whose opposed inner ends a circular opening is formed for the passage of the brush rod and between whose outer ends connected to the inner wall apertures are provided opening into the lower cylindrical section, and wherein between the upper end of the brush rod and the sealing flange a piston like section is provided, whose axial length corresponds substantially to the axial length of the upper cylindrical section, whose diameter is somewhat smaller than the inside diameter of the upper cylindrical section, and which comprises at its lower end an annular wiping lip lying against the inside wall of the upper cylindrical section.

Abstract
A closure for a bottle for correcting fluid consists of an insert (2) of yieldable plastics material fitted in the bottle neck (1a) and of a brush part (7) with a brush rod (8), fitted into a closure cap (14). The insert (2) is provided with a flange (3) lying on the upper edge of the bottle neck (1a) and with a tubular piece (4) connected thereto, which comprises an upper, also inwardly cylindrical section (4a) adjoining the flange (3) and a lower cylindrical section (4b) projecting freely into the interior of the bottle. Both sections (4a, 4b) have approximately the same inside diameter and at the lower end of the upper section (4a) there are provided a plurality of tongues (5) directed obliquely downward to the axis (A) of the insert (2) from the inner wall of the cylindrical section (4a), between whose opposed inner ends (5a) is formed a circular opening (6) for the passage of the brush rod (8) and between whose outer ends (5b) connected to the inner wall are provided apertures (9) open to the lower cylindrical section (4b). Between the upper end of the brush rod (8) and a sealing flange (11) arranged at the upper end of the brush part (7) there is provided a piston like section (12), whose axial length corresponds to that of the upper cylindrical section (4a), whose diameter is somewhat smaller than the inner diameter of the upper cylindrical section (4a) and which comprises at its lower end (12a) an annular wiping lip (13) which lies against the inner wall of the upper cylindrical section (4a).
