Liquid dosing device

The liquid dispenser according to cl. 1, which differs in that a ring sealing gasket is installed under the lid of the cylindrical body.

The liquid dispenser according to cl. 1, which differs in that it has a fixing element of the lid of the cylindrical body, made in the form of latches or a turn of thread, where in the upper part of the lid there is a recess with latches, in which the protrusion of the cylindrical body is fixed, and in the lower part there is an inner cylindrical protrusion, wherein there is at least one annular protrusion, which fits tightly to the cylindrical body.

The liquid dispenser according to cl. 1 which differs in that the inlet opening of the cylindrical body is closed by a drop-out plug.

The liquid dispenser according to cl. 1, which differs in that the bore of the cylindrical body in which the lever of the measuring cylinder is arranged is connected to the upper end portion of the cylindrical body, and the free exit of the lever from the cylindrical body is preempted by means of latches mounted on corresponding wall portions of the upper end portion of the cylindrical body, and has a height which is greater than the height of another wall portion of the upper end portion of the cylindrical body.

The liquid dispenser according to cl. 1, which differs in that in the lower part of the cylindrical body there is at least one retainer (latch or annular protrusion) which, when the cylindrical body is moved to its upper working position, contacts the gasket or the lower edge of the lid of the cylindrical body and prevents it from coming out of the lid.

The liquid dispenser according to cl. 1, which differs in that the cylindrical wall adjacent to the bore in the measuring cylinder through which the graduated piston enters and leaves the cylinder is provided with at least one annular protrusion (recess) which comes into contact with the annular recesses (protrusions) on the graduated piston.

Liquid dispenser according to cl. 1, which differs in that on the graduated piston through each scale graduation are made annular recesses (protrusions), which step coincide with the annular recess (protrusion) in the cylindrical wall of the measuring cylinder and fix its position, and at least one latch or annular protrusion is installed at the bottom of the graduated piston, which prevents the graduated piston from completely leaving the measuring cylinder.

The liquid dispenser according to cl. 1, which differs in that on the outer surface of the measuring cylinder on the lever side there is a longitudinal recess starting under the lever and ending at the edge of the lower opening of the measuring cylinder, which, when moving the measuring cylinder upwards to pour the measured liquid, connects with the lower part of the longitudinal opening of the cylindrical body in which the lever moves.

The liquid dispenser according to cl. 1, which differs in that the outer surface of the measuring cylinder is provided with at least one annular protrusion.

The liquid dispenser according to cl. 1, which differs in that an additional outer cover is made on the top of the device, which contacts the outer part of the dispenser cover and prevents moisture and dust from getting on the dispenser parts, and blocks access of the outside environment to the liquid, which is stored, in the container between its use.
