Abstract: Pump operable manually or by a utensil held by a user, having an elastically deformable chamber, the inside of which contains a liquid or viscous product, and the outside of which is brought into contact with air at a slit made in this chamber and with a replacement fluid at an opening made on the chamber. The chamber is suited to deforming, by pressing of a user, to create a higher pressure in the product compared to the outside, and to open the slit, allowing a volume of product to escape from it. The chamber is suited to making its deformation elastically disappear, upon cessation of the pressing, to create a lower pressure in the product, in the presence of a flow of replacement fluid through the opening towards the inside, and to close the slit, where the chamber wall is planar in the vicinity of the slit.

Abstract: The present invention relates to a mixer tap for discharging a mixture of liquids, comprising a moving plate mixing system (18) provided with a mixing channel (22), moving in translation on a fixed plate (19) provided with orifices for the inlet of liquids and the outlet of the mixture of said liquids after passing through the mixing channel, characterised in that it comprises a lever (15) angularly orientable in a plane between an angular minimum and a maximum, to vary the flow of the mixture, the lever being capable of pivoting, at constant angular orientation, around one direction of the plane, forming an axis of rotation for a moving cylinder (0) in a fixed tap body, the cylinder being linked to the lever in this movement, to vary the liquid content of the mixture, in that it comprises first means of discharging the mixture, by orienting the lever on one side of a stop position, on the one hand, and stopping the flow of mixture by orienting the lever in a vicinity of the stop position, on the other hand,

Abstract: Dispenser of liquid or viscous product, characterised in that it comprises a cup (3, 17) to receive the product, a sole piece to support the dispenser, a pump, comprising a pump body (13) and a piston, to transport the product from a reserve of product up to the cup (3, 17), the sole piece and the cup (3, 17) being connected by a hinge, the pump being inserted between the sole piece and the cup (3, 17) so as to transport the product when the piston is squashed on the pump body (13) by the movement of the cup (3, 17) in relation to the sole piece, the cup (3, 17) and the sole piece extending beyond the pump in relation to the hinge to enable the squashing of the piston on the pump body (13) by a user pressing with a utensil on the cup (3, 17).

Abstract: Pump operable manually or by a utensil held in one hand by a user, characterised in that it comprises an elastically deformable chamber (10), the inside of which is suited to containing a liquid or viscous product (8) and the outside of which is intended to be brought into contact with air at a slit (7) made in this chamber (10) and brought into contact with a replacement fluid at an opening (6) made on said chamber, in that the chamber is suited to deforming elastically, by a pressing of a user, to create a higher pressure in the product (8) compared to the outside, and to open the slit (7), allowing a useful volume of product (8) to escape from it, in that the chamber (10) is suited to making its deformation elastically disappear, following the cessation of the pressing of the user, to create a lower pressure in the product (8), in the presence of a flow of replacement fluid through the opening (6) towards the inside, and to close the slit (7), and in that the wall of the chamber (10) is essentially planar
