Abstract

The invention relates to a container closure (1) with a drip device for liquid containers for dosing and filtering liquids, comprising a base part (2) to be positioned in the liquid container, a liquid outlet opening (5) on the base part (2) and at least one liquid outlet opening (5) Retention device (12). The retaining device (12) is formed by a plurality of ramp elements (13) arranged at the base part (2) distributed around the liquid discharge opening (5) and having a rising height towards the liquid discharge opening (5).

Description

technical field [0001] The invention relates to a container closure device with a drip device for a liquid container for drop-by-drop dosing of a liquid, in particular for medicinal substances. Background technique [0002] Container closure devices and filter devices for draining and filtering liquids are known in the prior art. The disclosed container closure device comprises a base part to be arranged in a liquid container and a liquid outlet opening on the base part, wherein a blocking device is assigned to the liquid outlet opening. US 2009 / 0283545 A1 and WO 2008 / 131323 A1 disclose mesh filters and sieve filters as blocking devices for this purpose, which are intended to prevent clogging of the outlet of the container closure by solid particles. US 2 411 435 A and DE 10 2009 016 788 A1 show container closures for drop-by-drop dosing, in which the outlet tube arranged on the base part and extending into the container has a beveled angle, whereby the The drain port is c...
