FIELD: product dispensing devices.

SUBSTANCE: invention relates to a method for manufacturing a product dispensing device. The technical result is the exclusion of unfilled cavities in the product dispenser. The technical result is achieved by a method for manufacturing a product dispensing device (1), which includes providing a device (1) containing a reservoir (3). Moreover, the specified tank is connected to a deformable chamber (45) and is equipped with a filling hole (8). The inner part of the deformable chamber is limited at least partially by a movable wall (13), the displacement of which provides a change in the volume of the deformable chamber, and is separated from the reservoir by a supply valve (4) and/or separated from the outlet (6) of the device by a dispensing valve (5), and separated from the tank or from the outside by a filling valve (41). Carried out by means of the filling tube (50, 60) the step of filling the deformable chamber (45) with the product through the filling valve (41) and/or the step of filling with the product, preferably inside the channel (221), so that the product comes into contact with the filling valve (41) on the side reservoir (3) and/or on the side of the deformable chamber (45).

EFFECT: closing step in which the filling hole is closed.
