Products {PRODUCT}

The present invention relates to an infusion and administration device for liquid laundry detergent. The device according to the invention is especially adapted for pretreating the fabric with part of the liquid detergent.

Dosing devices for liquid detergents which are put into the washing machine together with the fabric are known in the art. It is also known that great effects can be obtained in the pretreatment of fabrics to remove stains without consuming large amounts of liquid detergents. 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 pretreatment device for a liquid detergent with a fixed sprayer 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 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. Depending on the size of the stain itself, a large amount is also required. 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 special requirements. Indeed, outlet nozzles or spreaders with a fixture, for example a sponge, may be used to change the amount of liquid detergent to be dispersed in the fabric for thorough pretreatment and / or to prevent ultimate damage to the fabric (ie discoloration, etc.). It does not offer the possibility to adjust the amount. 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.

According to a first aspect of the present invention, there is provided a liquid detergent comprising: a hollow body having a portion comprising a flexible material, an opening in the flexible portion, and means for dispersing at least a portion of the containing liquid detergent on the surface of the fabric. Infusion and administration devices, wherein the opening is (gradually) opened when pressure is applied to the surface of the device to which the liquid detergent is applied, and the opening is substantially closed when the pressure is released. Infusion and administration devices are provided.

According to a first aspect of the present invention, there is provided a liquid detergent comprising: a hollow body having a portion comprising a flexible material, an opening in the flexible portion, and means for dispersing at least a portion of the containing liquid detergent on the surface of the fabric. Infusion and administration devices, wherein the opening is (gradually) opened when lateral pressure is applied to the surface of the device to which the liquid detergent is applied, and the opening is substantially closed when the pressure is released Detergent infusion and administration devices are provided.

It has been found that the container of the present invention is particularly advantageous in that the amount of detergent injected from the device and the dispersion of the detergent on the surface to be treated are quite beneficial. These advantages include fast / enhanced control of detergent discharge from the device through the application / removal of the pressure applied to the device. In addition, the device of the present invention may provide for the application of friction / rubbing action and pressure.

In general, the opening is located in the bottom portion of the device. This allows the injection of detergent (with the aid of gravity) to the surface to be treated. To achieve this object, the flexible material portion is preferably located at the bottom portion of the device.

Preferably, the device comprises a plurality of openings. This allows for effective detergent injection and dispersion onto the surface to be treated.

Preferably, the openings are in the form of slit valves. It is understood that such slit valves can be opened when pressure is applied to the slit valves. The applied pressure may be in the form of contact pressure to the surface or translational pressure (or a combination thereof) by movement to the surface.

Each slit valve may be one or more preferably a plurality of separate slit openings (ideally, approximately two openings for improved detergent discharge) (these openings may be arranged perpendicular to each other)-such In this way, the injection of detergent can be made even when the friction direction is perpendicular to some of the slit valves (ie, for any friction direction, some valves may be in the best condition to operate). If there are more than one slit openings, the openings may not be the same size.

Preferably, the slit valve is in the form of a protrusion from the surface of the flexible portion. Optionally, this protrusion may have a connecting frame. The frame is preferably rigid and may be part of a structure disposed adjacent to the flexible portion. It has been found through the frame that a fairly controlled collapse / partial collapse of the protrusions is possible, where under this variant the slit valves open to enable the flow of detergent.

In general, the flexible portion is in the form of a sphere / ellipse. Preferably, the outermost points of the slit protrusions define the secondary sphere / ellipse through a larger radius. It has been found that the radius of each sphere / each sphere determines the amount of pretreatment movement required for the user's hand.

In order to improve the penetration / dispersion of the detergent into the surface to be treated (usually the fabric surface), the device preferably comprises a dispersing means (preferably in the flexible part). Preferably, the dispersing means is in the form of protrusions. The protrusions can be linear or curved. In general, the apparatus is provided with a plurality of protrusions.

In general, the height of the projection is approximately equal to the height of the deformed valve. In this way, it has been found that the valves can be operated efficiently (ie without closing due to the "implosion" of the valve due to excessive friction).

In general, the projections are located in an area different from that of the valves. This allows the user to rub the fabric after injection of the product (and / or through a smaller pretreatment movement) without further administration. Preferably, the valves are located off center of the device to achieve this object.

In order to be available to the consumer, the apparatus generally comprises a gripping means. The gripping means preferably comprises a main body portion of the device into which the detergent is injected. The main body of the device is preferably formed to fit the user's hand but contain sufficient detergent for the pretreatment and washing steps. Thus, the main body portion has a volume of 50 to 200 cm ³ . The main body portion may comprise any geometry, but is generally based on an oval tapered towards its upper opening (to which detergent is injected) and also at its lower end (adjacent to the flexible portion).

In general, the device is composed of an elastic plastic material. The main body portion may comprise PP, PE or PET (injected or blow molded). The protrusions and valves may comprise any rubber or elastomer suitable for welding, melting or bonding to the main body portion.

According to a second aspect of the present invention, there is provided a process for pretreatment and washing of fabric in a washing machine using the infusion and dosing device according to any one of the preceding claims, which process: Injecting a total amount of liquid detergent into the infusion and administration device; Pretreatment of the fabric is carried out via a controlled amount of liquid detergent infusion contained in the device and administered from the device through the valve; So that the pretreated fabric is placed in the drum of the washing machine together with the injection and dosing device and the other untreated fabric.
