Abstract
A device for dispensing a fluid product, comprising a rigid cylindrical body having a vertical main axis, a rigid piston which is oriented essentially horizontally and which can slide vertically inside the body, and an upper extraction wall which closes the upper end of the body. According to the invention, the body, the piston and the upper wall define a space that is intended to be filled with the product to be dispensed. In addition, the upper wall comprises a slotted cover that can open in order to connect the space to the exterior. The upper wall is elastically deformable and can deform into the space when a pressure is exerted manually on the upper wall, so as to increase the pressure inside the space and cause the slotted cover to open.

1-12. (canceled)
A dispensing device (10) for dispensing a fluid product including a rigid cylindrical body (12) the main axis of the body (12) of which is vertically oriented, a rigid piston (14) mainly horizontally oriented and which is slidably movable along the vertical direction inside the body (12), and an upper sampling wall (24) which plugs the upper end of the body (12),
- wherein the body (12), the piston (14) and the upper wall (24) delimit a volume (26) for being filled by a product to be dispensed;
- wherein said upper wall (24) includes a slit stopper (28) which is able to be opened to enable said volume (26) to be connected with the outside,
- wherein said upper wall (24) is elastically deformable and is able to be deformed inwardly of said volume (26) when a pressure is manually exerted on the upper wall (24), to cause an increase in the pressure inside the volume (26) and cause the slit stopper (28) to be opened,
- wherein the piston (14) bears an O-ring (20) which is radially compressed between an inner cylindrical wall (18) of the body (12) and a wall (66) of the piston (14), said wall (66) of the piston (14) including a conical-shaped segment (70) opened into the upper wall (24) against which the O-ring (20) bears when the piston is driven to move apart from the upper wall (24).
A dispensing device (10) for dispensing a fluid product including a rigid cylindrical body (12) the main axis of the body (12) of which is vertically oriented, a rigid piston (14) mainly horizontally oriented and which is slidably movable along the vertical direction inside the body (12), and an upper sampling wall (24) which plugs the upper end of the body (12),
- wherein the body (12), the piston (14) and the upper wall (24) delimit a volume (26) for being filled by a product to be dispensed;
- wherein said upper wall (24) includes a slit stopper (28) which is able to be opened to enable said volume (26) to be connected with the outside,
- wherein said upper wall (24) is elastically deformable and is able to be deformed inwardly of said volume (26) when a pressure is manually exerted on the upper wall (24), to cause an increase in the pressure inside the volume (26) and cause the slit stopper (28) to be opened, and
- wherein the dispensing device further includes a spring (32) which is vertically compressed between the piston (14) and a bottom plate (34) attached to the lower end (12i) of the body (12) to prevent the piston (14) from moving apart from the upper wall (24) when a pressure is exerted on the upper wall (24).
