Embodiment Construction

[0036] First, the general and very specific actions of dosing will be shown, since this is the subject of WO 2015 / 150250 A1. figure 1 A first stationary part of the dosing device is shown, namely a hollow cylindrical cup 4 with a transverse window 12 . Essentially it is just a hollow cylinder which is therefore closed at the top with a cover 13 which is flat in the example shown but can also have a shape deviating from the plane. Its window 12 is recessed at the upper end of the peripheral wall and extends there for half the circumference. The radius of the cover 13 at its edge in the region of the outer edge extending along the upper edge of the window reduces the wall thickness of the peripheral wall. Then, its outer slightly inwardly offset edge 25 extends on both sides for a distance greater than half the circumference, so that on both sides of the window 12 a cutout 14 is formed in the cover 13 . Inside it, guide ribs are formed in the hollow cylindrical body of the cu...

Abstract

A dosing device used to pour a defined amount of neck from a container or hose. The dosing device consists of a mouth attachment that can be screwed or pushed onto the neck, optionally closed by a separate cap, and has a variable-volume dosing control chamber (14). It is characterized in that the dosing control chamber is filled from empty to full during pouring. The dosing control chamber is formed by the space between the control chamber definition and the inside of the dosing piston (10) and is filled with liquid when the dose is poured, while the liquid at (D1) flows down through the dosing piston (10 ) to the mouth (3). Finally, when the control chamber (14) is full, the downwardly displaced dosing piston (10) closes said mouth (3). The dosing amount to be poured is adjustable by being able to define the path of said dosing piston (10) on its side facing said container or hose. The control chamber delimiter is variably axially displaceable relative to the dosing device into the neck provided and can be held fixedly in any position.

Description

technical field [0001] The present invention relates to a dosing device for delivering a liquid supply in measured portions from a container having a neck, for example from a plastic or PET bottle or from a hose having a neck. Background technique [0002] Several designs of dosing caps or devices for metering out liquids are known. A very well developed dosing closure is disclosed in WO 2015 / 150250 A1 published on 08.10.2015 by the same applicant. It is intended for a neck, the dosing closure is used to deliver a defined dose from a container or hose and consists of a mouth attachment which can be screwed or pushed onto the neck and can optionally be closed with a separate cover. A closure body is held on the mouth attachment, which closure body contains movable dosing means for delivering a specific dose in each delivery cycle. As a characteristic feature, the dosing device forms a variable-volume dosing control chamber, wherein the dosing control chamber is not dischar...
