Embodiment Construction

[0035] figure 1 An example of a container 1 for storing liquids such as colorants for paints, but also hair dyes, shampoos, foundations, etc. is shown. It can be used in a device comprising a plurality (eg twelve, sixteen or twenty) of such containers for dispensing a variety of formulations and preparations and located eg at a retailer of eg decorative paints.

[0036] The container 1 is equipped with or connected to a metering pump and valves (not shown). Further information on suitable dispensing devices and procedures for driving the various components is disclosed in eg European patent applications EP 800 858 , EP 1492 970 , EP 1 688 652 and EP 2 198 950 .

[0037] As shown, the container 1 of the present invention has a circular cross-section and comprises an agitator 2 with a rotatable shaft 3 extending through the center of the container. A plurality of paddles 4 are connected to the shaft 3 via a relatively thin arm 5 extending from the shaft at an inclination of eg...

Abstract

The invention relates to a container (1) for a viscous liquid, in particular a colorant for paint, comprising a stirrer (2) having a rotatable shaft (3) and a plurality of paddles (4) connected to theshaft (3). At least one of the paddles (4) and / or the connections (5) between the paddles (4) and the shaft (3) is flexible.

Description

technical field [0001] The present invention relates to a container for a viscous liquid, particularly a colorant for paint, comprising a rotatable shaft (eg, a single or composite shaft) extending through the center of the container and a shaft connected to the shaft. multi-blade stirrer. Background technique [0002] The Brownian motion of particles suspended in a liquid is insufficient to overcome gravity, and such particles tend to settle out of the liquid and aggregate. The coatings industry has struggled with this problem for over a hundred years. For successful application of colored colorants using a colorant dispenser, agitation (usually stirring) of the suspension is necessary. [0003] EP 2 198 950 relates to a device for dispensing multiple fluids (represented by number 1 in the figures of this publication) comprising a support (such as a turntable (2) or a linear table) mounted on the support (2 ) for containing a plurality of containers (4) of fluid, a pump ...
