Description

Dispensing and dispensing device for liquid detergents {A DOSING AND DISPENSING DEVICE FOR LIQUID DETERGENT}

The present invention relates to a dosing and dispensing device for liquid laundry detergent. The device according to the invention is especially adapted for pretreating the fabric with part of the liquid detergent.

Dispensing devices for liquid detergents which are fed into the washing machine together with the fabric are known in the art. It is also known that large effects can be obtained in terms of removing stains by pretreating the fabric without consuming large amounts of liquid detergent. Pretreatment means applying a certain amount of detergent directly to the stained portion of the fabric before the fabric is washed in the washing machine. In the following these devices are referred to as "pretreatment devices". Hereinafter, the detergent means a detergent composition for treating the fabric. This detergent composition may comprise laundry additives such as bleach, enzymes and / or other materials known in the art.

Various pretreatment devices for liquid detergents are described in the prior art, for example WO 92/09736 and WO 92/09737. These devices each allow the liquid detergent to be applied to the fabric prior to a wash cycle through a predetermined outlet or removable pretreatment applicator. Another treatment method is presented in EP-A-575 714. This document describes another liquid pretreatment device for a liquid detergent having a fixed applicator in the form of a roller ball. This roller ball can disperse a containing liquid detergent only in a predetermined direction.

The pretreatment devices mentioned above allow the containing liquid detergent to be evenly distributed in the fabric, i.e. the amount of dispersion is always the same. Even dispersion in this manner does not take into account that different stains require different amounts of liquid detergent during pretreatment. For example, stains may consist of certain ingredients that require more thorough pretreatment to increase the pretreatment effect. This can be achieved by applying a large amount of liquid detergent. In addition, a large amount is required depending on the size of the stain itself. Thus, it has been found that when a large amount of pretreatment detergent is applied to the soiled surface of the fabric, the stain removal effect is increased because the soiled surface can be more thoroughly pretreated.

With prior art pretreatment devices it is not possible to adjust the amount of liquid detergent according to specific needs. In practice, outlets or applicators, e.g. sponges with fixed openings, can change the amount of liquid detergent to be dispersed in the fabric for thorough pretreatment and / or prevent ultimate damage of the fabric (ie discoloration, etc.). You cannot control the amount of detergent. It is therefore an object of the present invention to provide an apparatus capable of regulating the flow of a liquid detergent for pretreatment.

It is an object of the present invention to eliminate / mitigate the above-mentioned problems.
