Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to the field of the preparation of liquid or semi-liquid capillary compositions, in particular for carrying out an operation for coloring or perming the hair . More particularly, the present invention relates to a hairdressing accessory in the form of a bowl for dosing, mixing, blending and / or removing components useful in the preparation of hair coloring.

STATE OF THE ART It is known to use a preparation bowl as an accessory in the field of hairdressing to produce compositions for hair coloring. For each coloration performed, a preparation bowl is necessary. Such bowls are described in EP 1 614 365 B1, EP 2 028 938 B1, US Pat. No. 7,537,120 B1. These bowls are particularly suitable for mixing several components to achieve a homogeneous composition of a certain color. Hair accessories, such as brushes or even applicator pads are most often used in conjunction with this type of bowl. However, the new trends in the field of hairdressing make that several dyes of different colors are applied on the same hair. Therefore, it becomes increasingly difficult for the professional hairstylist to easily handle all the accessories available to achieve such dyes because each color must have its own bowl preparation (sometimes five to six bowls are used at the same time time). In addition, the professional may inadvertently swap several bowls of preparation and may then apply a color in the wrong place on the customer's hair, forcing him to start again, in addition to the waste of product used and dissatisfaction of the customer. It is these drawbacks that the invention more particularly intends to remedy by proposing a device enabling the production of a plurality of hair compositions which is easy to use and maintenance, ergonomic, lightweight and usable by the professional of the hairstyle without the latter having to move continuously from his workstation.

According to the invention, the protuberance protruding from the bowl and the protuberance forming a cavity of the receptacle each comprise complementary fastening means capable of cooperating to keep the receptacle on the preparation bowl. Preferably, the protruding relief of the preparation bowl and the recess forming the container cavity are substantially semicircular or U-shaped flared. Preferably, the preparation bowl and the removable container attached to said preparation bowl form two compartments A and B of substantially equal volume. The preparation bowl may include a central transverse rib to facilitate insertion of the removable container directly into said preparation bowl. The preparation bowl comprises at least one wiping area and at least one profiled recess located on a portion of the inner portion of the side wall of said preparation bowl. The preparation bowl and the container may include graduations, preferably with numbers. The preparation bowl may comprise a gripping zone and advantageously additionally a spout. Another subject of the invention relates to a kit of hairstyle accessories comprising a device according to the invention and at least one additional hairstyle accessory selected from the group formed by removable containers, bristle brushes, applicator pads, whips, spoons, spatulas.

Another object of the invention relates to the use of a device or a kit according to the invention for producing a hair dye or a hair perm.
