Abstract

The equipment comprises a measuring and dispensing device of the reusable type for the machine washing of clothes, which comprises a hollow body (1) intended to receive the amount of liquid detergent prescribed for the wash, said body being provided with at least one filling opening (3) and outlets (7b) for the distribution of said product or products, as well as means (8) enabling the user to effect, once said device has been filled, the easy and controlled application of at least one product contained in it to selected areas of the clothing before the latter is subjected to washing in the machine, for the purpose of effecting the pretreatment of said areas before the washing cycle, said measuring and dispensing device, containing the amount of product remaining after the pretreatment, being introduced into the machine together with the clothes, said pretreatment means (8) being removable from the body of said device.

Claims

1. Equipment comprising a reusable measuring and dispensing device for use in the machine washing of clothes, said device comprising a hollow body closed at one end by a base and adapted to receive a predetermined amount of a product, said hollow body being provided with at least one filling opening and with outlets for distribution of said product, said device being adapted to be placed, together with clothes to be washed, in a drum of a washing machine, wherein said device is progressively emptied of said product during the course of a washing cycle, said device being further provided with pretreatment means for enabling a user to effect, once said device has been filled, a controlled application of a pretreatment amount of said product to selected areas of said clothes to accomplish a pretreatment of said areas before said washing cycle, said device, containing a residual amount of product remaining after said pretreatment, being introduced into said machine together with said clothes, and in that said pretreatment means are removable from said body of said device.

2. Equipment according to claim 1, wherein said pretreatment means is adapted to enable to said product to be distributed over said areas.

3. Equipment according to claim 2, wherein said pretreatment means comprises an applicator member adapted to receive said product by impregnation.

4. Equipment according to claim 3, wherein said applicator member comprises an applicator pad.

5. Equipment according to claim 4, wherein said applicator pad is adapted to be fixed sealingly in said filling opening.

6. Equipment according to claim 3, wherein said applicator member comprises a brush.

7. Equipment according to any one of claims 3, 4, 5, or 6, wherein said applicator member terminates in a handle fastened to an attached assembly adapted to be fixed sealingly in said filling opening of said device, said applicator member extending inside said body of said device when said attached assembly is in position in said filling opening.

8. Equipment according to claim 6, wherein said brush terminates in a handle fastened to an attached assembly adapted to be fixed sealingly in said filling opening of said device, said brush extending inside said body of said device when said attached assembly is in position in said filling opening, and wherein said handle extends an outlet chimney provided on said attached assembly.

9. Equipment according to claim 8, wherein the height of said brush does not exceed the height of said body of said device.

10. Equipment according to claim 1, wherein said device is provided with an attached assembly which forms a lid, said lid being provided with numerous small apertures intended to enable a user to spread by sprinkling said pretreatment amount of said product over said areas, said attached assembly being adapted to pivot on said body of said device between a position in which said lid closes said apertures and a position in which said apertures are not closed.

11. Equipment according to claim 10, wherein said body of said device is provided with outlets on a part which forms a rim at the level of said filling opening, said attached assembly forming a lid adapted to pivot on said part and being provided on its periphery with closure legs which are disposed and shaped in such a manner that, in one position of said attached assembly on said body, said outlets are closed by said legs, said legs being placed over said outlets, and in another position said outlets are no longer closed.

12. Equipment according to claim 10, wherein said attached assembly has a dome-shaped lid part, said body being provided with a complementary sub-dome equipped with distribution outlets, said dome-shaped lid part being provided with complementary outlets which, in one position of said attached assembly in relation to said body, are adapted to assume a juxtaposed position relative to said distribution outlets in order to establish communication between the interior of said device and the exterior and, in another position, to interrupt said communication.

13. Equipment according to claim 1, wherein said pretreatment means comprises a member fastened to said body of said device or to an assembly attached to said body, said member having a pouring spout or channel communicating with the interior of said body when said member is in position on said body or on said assembly attached to said body.

14. Equipment according to claim 1, wherein said body has a wall forming a valve which, depending on whether or not said valve is subjected to a stress, controls communication between the interior of said device and a product application member.

15. Equipment according to claim 14, wherein said product application member comprises a hollow tube which extends inside said body of said device, passing through said base and terminating, outside said device, in an application surface, the wall which delimits said tube in the interior of said body being deformable and provided with at least one slit forming a valve which, if a compressive force sufficient to deform said wall is applied to said application surface, will open and bring the interior of said body into communication with the interior of said hollow tube, thus enabling said product to reach said application surface.

16. Equipment according to claim 15, wherein said application surface is provided with irregularities.

17. Method of utilizing the equipment according to claim 1, wherein said device is filled with a total amount of liquid detergent prescribed for a wash, a controlled pretreatment amount of said total amount of liquid detergent is applied to selected areas of said clothes with the aid of said pretreatment means, and said device is then placed in said drum of said washing machine together with said clothes, said device containing the residual amount of said detergent remaining after said pretreatment amount is applied to said clothes.

18. Process for pretreating and washing clothes in a washing machine, comprising the following steps:

(a) a dosage of the total quantity of liquid detergent to be utilized during a washing cycle is introduced into a measuring and dispensing device;

(b) said clothes are pretreated with a controlled pretreatment quantity of said total liquid detergent dosage contained in said device; and

(c) said clothes and said device containing the residual quantity of liquid detergent remaining after said pretreatment quantity is applied to said clothes are placed in a drum of said washing machine, such that the residual quantity of liquid detergent is used for said washing cycle.
