Definitions

  • the invention relates to a cover with a vent valve according to the preamble of claim 1.
  • the axial channel of the bushing does not extend to the hole in the bottom of the cover, so that the bushing does not assume a defined position. Rather, the socket must be screwed into the ring collar, the screwing depth of which is indefinite.
  • the retaining ring for the valve ball is also screwed into the axial channel of the socket and also has no predetermined seat depth.
  • a cover with an axial channel in which a spring which is supported against a shoulder in the axial channel and a displaceable closure body for a bore in a plug shaft which is likewise inserted into the axial channel can be inserted in succession. Pre-assembly of the vent valve formed in this way is not possible.
  • a valve ball in a vent valve which can be made of plastic.
  • a ball in a vent valve is known, which can consist of stainless steel.
  • the object of the invention is to provide a preassembled vent valve, the opening pressure of which can be set in a reproducible manner and which fits into conventional covers, in particular screw caps.
  • the lid with this vent valve is suitable for packaging of gassing products, which would otherwise cause the vent valve to swell, for opening pressures to be determined between 0.05 and 0.2 bar.
  • an embodiment according to claim 4 is preferably provided.
  • a particularly secure fit of the valve is obtained with an embodiment according to claim 5.
  • the vent valve 2 is inserted into a cover 4 designed as a screw cap.
  • a channel 10 extends axially through the bushing 8 and widens in the direction of a hole 12 in the bottom of the cover 4 via a conical step 14.
  • a valve ball 16 made of polypropylene.
  • a retaining ring 20 made of polyethylene is supported against the inner annular shoulder 18 in an annular recess of the bushing 8 which surrounds the axial channel 10 next to the hole.
  • a compression spring 22 made of V4A steel is arranged between the retaining ring 20 and the valve ball 16.
  • the axial channel 10 has a diameter of 2 mm in its narrow area, a diameter of 5.9 mm in its wide area, the valve ball 16 has a diameter of 5 mm and the compression spring has a diameter of 5.6 mm and four turns with a wire diameter of 0.5 mm and finally 5.6 mm in the relaxed state, the opening pressure of the valve is constantly between 0.05 and 0.2 bar.
  • the peripheral surface 24 of the ring recess is provided with a projecting, annular locking web 26 for receiving in a corresponding annular notch 28 in the peripheral surface 30 of the retaining ring 20.
  • a section 32 of the bush 8 adjacent to the cover 4 tapers from a diameter 34, which is somewhat larger than the diameter of the inner surface of the ring collar, to the diameter of the inner surface of the ring collar in the direction of the cover 4.
  • the bushing 8 is pressed flush with the valve ball 16 and the compression spring 22 into the ring collar 6. If the lid is screwed onto a container with a gassing product, the valve ball 16 is pressed against the compression spring 22 in the event of overpressure and the axial channel 10 to the hole 12 is thereby opened.
  • Vent valves of the type described were stored in TBPEH (t-butyl-per-2-ethylhexanoate) for three months and then proved to be unswollen and consistently stable with a reproducible opening pressure between 0.05 and 0.15 bar.
  • the conical tapering of the bushing allows it to be inserted easily into the ring collar 6 and yet is firmly seated in the ring collar 6.
