  • the prior art liquid dosing unit according to US patent 5169037 (prior. 26.01.1990, applicant CCL Industries Inc, IPC B65D83/62). It consists of a housing into which a flat-bottomed capsule with flexible walls is inserted, hermetically connected to a valve made in the upper part of the housing. Initially, the capsule is in the folded state. When the case is closed hermetically, liquid is pumped into the capsule. In this case, the capsule expands, and its bottom opens along the inner surface of the bottom of the body. After the capsule has been filled with liquid, a gas injection means is connected to the housing, by means of which the liquid is squeezed out of the capsule. As the amount of liquid in the capsule decreases, the pressure will gradually decrease.
  • the process stops after squeezing out all the liquid from the capsule.
  • the capsule can then be filled with liquid again.
  • the disadvantage of this node is that the volume of dosing is equal to the volume of the capsule, the consumer cannot control the size of the received portion of the liquid. It is also a disadvantage that the dosing rate is non-uniform, as the pressure decreases during the process, which limits the application of this invention.
  • the liquid dispensing assembly is known from the prior art according to US patent 5607082 (prior. 06/01/1995, Applicant HD Hudson Manufacturing Co, IPC B05B9/0838).

  • the node according to patent US5607082 works as follows. The folded capsule is placed in the body, after which it is filled with liquid and closed. Through the gas injection means, a compressed gas is supplied into the space inside the housing around the capsule, which pushes the contents of the capsule through a tube inserted into the neck of the housing. After squeezing out all the liquid, the dosing process stops.
  • the disadvantage of this node is that the dosing volume is equal to the volume capsules, the consumer cannot regulate the size of the received portion of the liquid, that is, there is no possibility of regulating the volume of liquid supplied.
