Definitions

  • the present invention relates to a dosing and dispensing device for liquid laundry detergents.
  • the device according to the present invention is particularly adapted to pretreat fabrics with a portion of liquid detergent.
  • Dispensing devices for liquid detergent which are to be introduced with the fabrics in the washing machine, are well known in the prior art. It is also known that it is possible to achieve a greater effectiveness in respect of stain removal by pretreating the fabrics without consuming a greater amount of liquid detergent.
  • Pre- treatment means that a certain amount of detergent is applied directly onto the dirty parts of said fabrics before they are washed in the machine. In the following these devices are called “pretreat- ment devices”.
  • detergent means a detergent composition for the treatment of fabrics. This detergent composition may comprise washing additives, like beaches, enzymes and/or others known in the art.
  • pretreatment devices for liquid detergent are described in the prior art, for example in WO 92/09736 and WO 92/09737. These devices allow an application of said liquid detergent onto the fabrics before the washing cycle either with predetermined outlets or a removable pretreatment applicator respectively.
  • Another approach is represented by EP-A-575 714.
  • This document describes another pretreatment device for liquid detergent with a fixed appli- cator in form of a roller ball . This roller ball is able to spread the contained liquid detergent only in a predetermined direction.
  • pretreating devices mentioned before allow an even spreading of the contained liquid detergent onto the fabric, i.e. the spread quantity is always the same. This way of even spreading does not consider that different stains need a different amount of liquid detergent during pretreatment. For example, stains can be made of certain constituents which need a more thorough pretreatment to increase its effectiveness. This can be achieved by applying a greater amount of the liquid detergent. A greater quantity is also needed depending on the dimensions of the stain itself. Therefore, we found that the effectiveness of stain removal is increased when a greater amount of pretreating detergent is applied upon the soiled surface of the fabric, since said surface can be pretreated more thoroughly.
  • a dosing and dispensing device for liquid detergent comprising a hollow body having a portion comprising a flexible material, an opening in said flexible portion, and means to spread at least a portion of the contained liquid detergent onto a surface of fabric, characterized in that said opening being (progressively) opened when pressure is applied to said device on a surface to which the liquid detergent is applied, and said opening being substantially closed when said pressure stops.
  • the container of the invention is particularly advantageous in that the amount of detergent dosed from the de- vice and the spreading of the detergent onto the surface being treated is surprisingly beneficial.
  • These benefits include quick / advanced control of discharge of the detergent from the device by the application / removal of pressure applied thereto. Additionally the device of the invention is able to provide a rubbing / scrubbing action as well as the application of pressure.
  • the opening is located in the bottom part of said device. This allows dosing of the detergent (aided by gravity) onto the surface being treated.
  • the portion of flexible material is located in the bottom part of said device.
  • the device comprises several openings. This allows effective dosage and spreading of the detergent onto the surface being treated.
  • the openings are in the form of a slit valve.
  • slit valves are understood to be capable of being opened when pressure is applied thereto.
  • the pressure applied may be in the form of contact pressure against a surface or translational pressure (or a combination thereof) caused by movement relative to a surface.
  • Each slit valve may have one or more preferably a plurality of separate slit openings (these may be arranged perpendicularly to one other - in this way it is possible to achieve dosing of the detergent even when the direction of rubbing is perpendicuiar to some of the slit valves (i.e. for any rubbing direction some valves will be in the best condition to work)), (ideally about two openings for enhanced discharge of detergent). Where more than one slit opening is present it can be that the openings are not of an equivalent size.
  • the slit valve is in the form of a protrusion from the sur- face of the flexible portion.
  • the flexible portion is in the form of a portion of a sphere / spheroid. It is preferred that the outermost points of the slit protrusions define a secondary sphere / spheroid, with a larger radius. It has been found that the radius of the / each sphere determines the amplitude of the pretreating movement required by the user's hand.
  • the device preferably on the flexible portion
  • the spreading means is in the form of a ridge.
  • the ridge may be liner or may be curved. Generally a plurality of ridges is present on the device.
  • the ridge height is about the same as that of a deformed valve. In this way it has been found that the valves may be activate efficiently (i.e. without being closed due to valve "implosion" following an excess of rubbing force.
  • the ridges are positioned in a different area to that of the valves. This allows a user, after the dosing of the product, to rub the fabric without further dispensing (and / or with a smaller amplitude of the pretreatment movement).
  • the valves are positioned away from the centre of the device.
  • the device comprises a gripping means.
  • the gripping means preferably comprises the main body of the device, into which the deter- gent is poured.
  • the main body of the device is preferably shaped so that it is capable of fitting into a hand of a user yet may contain sufficient detergent for a pre-treatment and laundry step.
  • the main body thus has a volume of from 50-200cm 3 .
  • the main body may comprise any geometrical shape but is generally based on an ovoid, tapering towards its upper opening (into which the detergent is poured) and also at its lower end (which adjoins onto the flexible portion).
  • the device is made of elastic plastic material .
  • the main body may comprise PP, PE or PET (both injected or blow moulded) .
  • the ridges and the valves may comprise any rubber or elastomer suitable for being welded, melted or glued onto the main body.
  • a dosing and dispensing device for liquid detergent comprising a hollow body having a first portion comprising a first flexible material and a second portion comprising a second flexible material, wherein the flexibility of the second material is greater than the first material, an opening in the second portion, and means to spread at least a portion of the contained liquid detergent onto a surface of fabric, characterized in that said opening being (progressively) opened when pressure is applied to said device on a surface to which the liquid detergent is applied, and said opening being substantially closed when said pressure stops.
  • the first portion comprises PP, PE or PET (both injected or blow moulded).
  • the two portions preferably allow co-joining. This may be by weld- ing, adhesion (with or without an adhesive) and / or in a combined manufacturing process (e.g. in a co-extrusion process).
  • the second (which may include the ridges described above) comprise a rubber (natural or otherwise), a silicone resin or a flexible elastomer. It has been found that best results are achieved when rubber is used as the main component of the second portion. This allows (repeated) temporary deformation of the second portion, thus allowing effectively yet controlled release. It has been found that more rigid polymer functions less well in this arena since the temporary deformation required has been found to result in more permanent deformation which detrimentally affects dosing capacity.
  • a process for pretreating and washing fabrics in a washing machine with the dosing and dispensing device characterized in that it comprises of the following steps: a dose of the total quantity of liquid detergent to be utilized during the pretreatment and washing cycle is introduced into the dosing and dispensing device; pretreatment of the fabrics is executed with a controlled quantity of the liquid detergent dosage contained in said device and dispensed from said device through said cut; the thus pretreated fabrics are placed in the drum of the washing machine together with said dosing and dispensing device and with other non-pretreated fabrics.
  • the device is for a laundry cleaning formulation and for use in dispensing same onto a clothing surface.
  • the laundry cleaning formulation comprises a bleach, e.g. in an amount of from 0.001% to 99.99%, preferably 0.001% to 20%, preferably 4% to 18%, e.g. most preferably about 4.5% or 13%, by weight, of bleach.
