An appliance for manual use for massaging a cutaneous covering, comprising, on the one hand, a reservoir (1) containing the product to be applied, and integral with a gripping element (2), the reservoir comprising a movable wall (4), so as to adapt its internal volume (9) to the quantity of product contained and, on the other hand, an applicator element (3) constituted by a sole (6) cooperating with the reservoir (1) and comprising at least one ball (7) held in a housing (8), which communicates with the internal volume of the reservoir (1) through at least one opening. The appliance also comprises a direct current source (12), which is situated in the said gripping element (2) and whose poles are each connected to one electrode, the first electrode (13) being a conductive covering which covers the wall of the gripping element (2) and the second electrode (14) being constituted by a conductive film which is in permanent contact with the product situated in the reservoir (1).

The method for measuring the elasticity of a superficial layer (2), in particular of the skin, comprises defining a zone (7) of this layer; creating a negative pressure in this zone to cause a deformation of the zone; and measuring the negative pressure necessary to cause a deformation of predetermined amplitude. The measuring device includes a sensor (3) provided with a cavity (5) defined by a rim (6) arranged to be pressed against the layer (2) to be studied, and a pump (17) for creating a negative pressure in the cavity (5). A suction opening (20) is provided in the cavity at a predetermined distance (d) from the superficial layer, in such a manner as to be obturated by the layer when the deformation attains the predetermined amplitude. A pick-up device is provided for measuring the negative pressure that has produced the deformation of predetermined amplitude.

The dispenser comprises a shell enclosing a movable reservoir for the product. A dispensing valve is formed in a zone between the shell and the reservoir. Control member allow a relative displacement to be effected between the shell and the reservoir to open the dispensing valve and to allow the product to flow out. Openable passage are capable of connecting the inside of the reservoir to the atmosphere when the control member are actuated to open the dispensing valve.

Liquid product dispenser, in particular for a cosmetic product such as

A cell for the measurement of the dielectric properties of liquids, pastes or flowable solids (i.e. solids whose melting temperatures are low enough to allow them to be poured into the cell) comprises a bullet-shaped internal electrode having its cylindrical portion in register with a surrounding coaxial cylindrical external electrode which is extended at each end by electrically conductive annular guard members insulated from the external electrode by means of spacers of electrically insulating material. The internal electrode is mounted coaxially within the external electrode by means of a tapered male-female centering connector whose male and female elements are both connected to earth.

A method and device for forming openings in a gelatinous substance in a Petri dish in which the Petri dish (6) is lifted towards punch tools (19) until the tools have penetrated the gelatinous substance and are on or near the base of the dish. The dish is then moved with a low amplitude motion perpendicular to the penetration direction, i.e. horizontally to loosen a pellet of the gelatinous substance within each punch tool from the base (6a) of the dish, and finally the dish is lowered to withdraw the punch tools (19) from the dish while suction applied to a compartment (4) communicating with the interior of each tool extracts the punched pellet and clears the tool for a subsequent penetration in the same or a different dish (6).
