AI Technical Summary

Problems solved by technology

The inventors have realized that problems in the prior art can be found in this, since the viscosity of one material or the other or both materials may vary due to fluctuations depending on the filling charge, which has the following consequences: In the case of viscous fluctuations, ultimately the predetermined mixing ratio cannot be followed and degraded results can thus be achieved
If, for example, in the case of hair dyes, where hydrogen peroxide is therefore often used as one substance and a coloring agent as another substance, even small fluctuations in viscosity can lead to different color effects, such as Even slight fluctuations in viscosity when it is desired to dye black can lead to an undesired bluish sheen in the hair, which in turn can have a negative impact on the sales of this dispenser

Embodiment Construction

[0052] Subsequently, the invention is described on the basis of a preferred embodiment, more precisely for a dispenser in the basic construction type of a dispenser according to WO 2015 / 128092 A1. Here, the core of the present invention is the addition of a metering pump, and the core of the present invention can correspondingly also be applied to other pumps with other structural types.

[0053] In this respect, the features described with respect to the dispenser in connection with the illustration of the invention are also disclosed in other embodiments of the dispenser, so that the independent protection for the features described in this case is deduced as follows : These features themselves can of course also be applied to other construction types of dispensers independently of the context in which they are described subsequently, ie can be selected individually. In this respect, these characteristics must be regarded as generalized.

Abstract

In a dispenser for dispensing at least two liquid or pasty substances from receptacles to a dispenser head, constant delivery pumps are connected therebetween to compensate for viscosity variations and keep a given mixing ratio constant.

Description

technical field [0001] The invention relates to a dispenser for substances, in particular liquid or pasty substances, according to the preamble of patent claim 1 . Background technique [0002] Such dispensers are known, for example, from WO 2015 / 128092 A1. This document describes a dispenser for discharging a substance, more precisely for dispensing two substances, each of which is contained in a flexible container, in particular a foil pouch, and Both of the foil pouches are arranged in a housing with flexible side walls made of plastic material. Each bag includes a dispensing tube that leads to a funnel-shaped dispensing orifice that leads to a dispensing head, such as an applicator, for expelling the substance. In this case, these substances can be mixed with each other in the dispensing head in a predetermined mixing ratio, or else they can be discharged from the dispensing head or applicator separately from each other through 2 nozzles or corresponding dispensing hol...
