Definitions

  • the invention relates to closure structures for containers mounted on the necks of containers for storing and dispensing liquid in a pressure vessel and can be used for storing and dispensing PET beverages made from PET and intended for automated bottling.
  • Containers with valve constructions mounted on them are used for storing and bottling beverages, such as beer, for example.
  • These valve constructions have several channels that allow the passage of fluid and gas.
  • the beverage When filled, when the container is usually in an upside-down state, the beverage is introduced through the first channel of the valve construction, while the gas displaced from the container leaves the second channel.
  • the filling head is hermetically connected to the valve design, through which gas (nitrogen or carbon dioxide) is fed into the container through the first channel in order to force the beverage out of the container through the second channel.
  • the filling head attached to the valve structure acts on the spring-loaded elements of the valve structure and then opens the channels.
  • the sealing element of the valve construction serves to maintain the created overpressure inside the container when removing (dismantling) the casting head.
  • the overpressure is approximately 2.5 - 3.0 bar.
  • the specified pressure is the working pressure of the PET tank.
  • PET capacity withstands a pressure of about 7-8 bar.
  • Famous cover for a sealed container comprising a housing, at least one valve element configured to move relative to the housing between closed and open positions; and a locking mechanism configured to hold the valve member in the open position; moreover, the locking mechanism has first and second parts, where the first part can move due to the impact of the valve element and contains a locking element that can engage with a counter element on the body to hold the valve element in the open position; and the second part can move due to the impact on it of the first part, when the valve element is moved from the closed position to the open position; however, when the valve member returns from the open position to the closed position, the first part can move relative to the second part; moreover, the specified relative movement of the first and second parts provides the coupling of the locking element with the counter element on the housing to hold the valve element when it returns to the open position.
  • the known design of the cover for the container has a complex structure.
  • Known capacity (patent for invention RU2466085, publ. 10.11.2012g.) Of plastic with valves and seals, in which valves and / or seals are made with the possibility of forming a non-closing through hole to release pressure inside the vessel after the previously performed opening process during the subsequent automatic closing process.
  • a non-closing through hole is formed due to the deformation of the stop of the shut-off valves in contact with the seal during container closing (taken as a prototype).
  • the main difference of the claimed invention from the prototype is the absence of destructible components of the container lid.
  • the technical problem of the claimed invention is to create a valve structure that ensures the tightness of the container in the process of pouring the drink and the depressurization of the container after emptying the container, and accordingly discharge the residual overpressure after the first use at the consumer.
  • the technical result is the safety of storage and disposal of used containers.
  • valve design for the tank contains a lid with a central hole with means for connecting to the neck of the tank, an annular nut, a spring, a hollow rod and a valve element arranged to move along the stem, while in the bottom part of the annular nut on the ribs a retaining ring adapted to move in the direction of the upper end of the cover and engage with the lower and upper edges of the valve seal.
  • FIG. 6 is a view of the locking ring.
  • the valve design includes a cover 1 with a central bore, a hollow rod 2 mounted along the longitudinal axis, a valve element 3, a spring 4 and an annular nut 5 providing its preload (FIGS. 1-5).
  • Valve design can be connected to the neck of the container 6 as a locking and threaded connection.
  • annular seal 7 To ensure the tightness of the connection valve design with the neck of the container on the end of the neck of the tank 6 is installed annular seal 7.
  • the rod 2 is made hollow in the form of a tube. One end of the stem is made open and passes through the hole of the ring nut 5, protruding beyond its limits. The second end of the rod 2 is made closed and provided with a protrusion. At the top of the hollow stem 2 is placed at least one window for the passage of the beverage during bottling.
  • a valve element 3 On the rod 2, with the ability to move along it, a valve element 3 is installed with a central bore, provided with an annular ledge arranged to interact with the protrusion of the hollow rod 2. Pressed valve element 3 to the annular protrusion of the cover 1 is a spring 4, installed between the ring nut 5 and the valve element 3. To prevent the material surface of the valve element 3 from being pushed, a sealing ring 8 is installed between it and the spring 4.
  • the fastening ring nut 5 to the cover 1 is a threaded connection.
  • the annular nut 5 at the bottom is provided with openings for the passage of liquid or gas.
  • stiffeners 9 are also provided, on which a retaining ring 10 is installed, made in the form of a split ring with perpendicularly arranged protrusions 11, provided with teeth 12 and 13 in the upper and middle part (Fig. 6).
  • the number of projections may be one or more. For a uniform centering of the ring in the housing, it is optimal to perform three protrusions that are equally spaced from each other.
  • the height of the protrusions 11 of the locking ring 10 is determined by the stroke of the sealing element, which depends on the type of casting head used, and the distance between the teeth 12 and 13 of the thickness of the sealing element 3, which is in contact with the inner wall of the cover 1.
