Description

Pouring and Dosiθrsystem

The present invention relates to spout and dosing systems for the simultaneous provision of two or more flowable contents, containing

Dosing device, product container and spreading device and their use for dosing flowable products

Generally, there is a need in the packaging industry for packaging that is lightweight and requires little material, i.a. so as to be perceived by the consumer as environmentally friendly. Furthermore, there is a trend, e.g. in the detergent industry, therein, contents, e.g. Detergents and cleaning products, in the form of multi-component systems offer, especially if individual components are not compatible. In such multi-component systems, it is important that they can be dosed in the right proportion to one another and that a given total quantity can be dosed correctly and simply.

Thus, various metering systems for the simultaneous metering of two liquids from bags and bottles are already known. EP 1245500 describes a multi-chamber bag with a multiple sampling channel. Similarly, US 2005/0109796 describes a flexible multi-chamber bag with a removal device which communicates with both chambers of the bag. These dosing systems are suitable for removing two products at the same time, and the ratio can be determined by the manufacturer when removing the two components. However, the total amount of the two components can not be determined by the manufacturer. Furthermore, the removal ratio of the contents can be set only inaccurate. An exact portionwise removal of the contents is therefore not possible. DE 10 2005 051 337 describes a dosing system consisting of a specially shaped multi-chamber bottle with an adaptive closure. This dosing system is suitable for dosing two liquids as an overhead dosing device so that the ratio of the components to one another and the total quantity can be determined by the manufacturer. However, this dosing system is not suitable for flexible or semi-rigid product containers. DE29511932 describes a dispenser, eg a two-chamber tube, for a medium composed of two components. According to the embodiment shown there, the ratio of the two components can be adjusted, but not the total amount to be dosed. US 4978025 describes a stand-up bag with spreading device and optionally present metering device. However, the bags described there are not suitable for dispensing several components.

An object of the present invention is therefore to eliminate the disadvantages of the known Dosiersysterαe. Further objects emerge from the description and the advantageous embodiments of the invention. In particular, there is a need for metering systems whose product containers are flexible or semi-rigid ("bags") and still provide the opportunity to dose several flowable products so that their

Ratio to each other and the total amount are predetermined or predeterminable.

The above-outlined objects are achieved according to the independent claims. The dependent claims represent advantageous embodiments.

The invention thus relates to a pouring and metering system for the simultaneous provision of two or more flowable fillers, the use of the pouring and metering system for metering flowable Fillings, in particular liquid detergents and cleaners.
