Definitions

  • the invention relates to a hollow or compressible sealing member which is entirely or for the greater part in the form of a cone and which, for example, can be used both in compressible and non-compressible holders for liquids or solids.
  • Liquids and solids which are attacked and/or will deteriorate in quality when exposed to air or by light cannot be stored and used in holders without the use of a sealing system.
  • the sealing member according to the invention consists of a thin flexible material and has entirely or for the greater part the shape of a hollow cone as is shown in Figures 1 to 4.
  • the sealing member operates as a non-return valve.
  • the circumference of the open end (the base plane) of the cone should correspond accurately to the inner circumference of the pouring opening of the holder to be sealed by means of the valve.
  • the circumference of the base plane of the cone is partly connected to the inner wall of the pouring opening.
  • the pressure build-up caused by the valve depends on the thickness and flexibility of the material from which the valve is manufactured. All this depends on the contemplated use of the valve.
  • Non-return valve 10 accor- ning to the invention is mounted in the neck 2u. This may be aone, for example, by connecting a part of the outer edge ot the base plane of the hollow cone and optionally of the outside ot the cone itself to the inner side of the neck 20 to be sealed, for example, by means of a part of a spring ring which clamps a part of the base plane in a circumferential recess in the pouring neck.
  • An optimum sealing is obtained by constructing the recess so as to be conical, preferably in such manner that the lower edge of said recess extenas parallel to the oblique side of the cone.
  • the contents are poured or sprayed in a receptacle by squeezing the holaer 30.
  • the valve 10 opens in that the part 21 of the cone not connectea to the neck 20 is pushed asiae (see Figure 2).
  • the valve closes immediately (depen- aent on the resistance of the valve material) when the pressure in 11 ana 12 becomes equal so that no ambient air is arawn in ana the contents of the holaer are not attacked. In this manner the holder can be emptied by squeezing like a tube.
  • Figures 3 ana 4 show a modified embodiment of the non-return valve shown in Figures 1 and 2.
  • the pouring neck 20 comprises a member with which the valve can be opened trom without and in this manner gets the function of a cock. This can be done in a way known per se, for example, by means of a compression spring pin 22 which comprises a pressure plate at the end near the valve.
  • valve in accordance with the invention is that a so-called dispenser can be obtained by using a combination of two valves in the same holder. This can be achievea by mounting one valve in the above-aescribea manner in the pouring neck, and providing a secona valve which operates oppositely to the first in a separate air drawing-in tube beside the pouring neck. when the pouring neck is provided with a graduation, a measurea quantity ot the contents can be collected in the neck by squeezing the holder and be drained by turning the holaer upside down. Via the second valve an equal volume of, optionally filter or aried, air is drawn in.
  • the resistance of the tirst valve may be so large that when the holder is turned upsiae aown the contents cannot leave the holder via this valve.
  • an excess, it any, can be made to flow back into the holaer.
  • FIG. 5 and 6 Another moditied embodiment of the Figures 1 and 2 valve is shown in Figures 5 and 6.
  • This embodiment may be used in holders which cannot be compressed, for example, glass holaers. Since the pressure below the non-return valve cannot be made larger than above the valve by squeezing such a holaer, the valve shown in Figures 1 to 4 coula not operate.
  • the modified embodiment shown in Figures 5 and 6 is suitable indeed for such an application. ln this embodiment the hollow conical non-return valve 10 has the shape ot half a cone. The other half (40) of the pouring neck 20 is now constructed so that air can be arawn in so as to enable pouring of the contents.
  • the choice of the filtering material 41 depends on the ena in view, for example, filtering the C0 2 or H 2 O present in the drawn-in air.
  • Tube 42 is bent so that the opening aoes not come below the level of the contents when the holder during pouring is kept in an inclined position and the drawn-in air need not overcome any resistance.
  • the valve according to the invention may also be used in holaers for low-boiling-point liquids which at room temperature have a considerable vapour pressure, for example, ether, or build up a vapour pressure by decomposition, tor example, hydrogen peroxide.
  • Holders with such liquids comprising the conical non-return valve according to the invention can be stored without any danger, When the vapour pressure in the holder exceeds a certain value, a quantity ot vapour is arained via the valve.
  • the over--pressure at which this happens, i.e. at which the valve opens, depends on the material ana/or thickness from which the valve is manutactured.
  • the valve operates as a safety valve.
  • the holder should comprise a cock which can be opened and closed for drawing-in air.
  • the base plane of the valve may comprise a cylinarical sleeve, which circumference should correspond accurately to the inner circumference of the opening to be sealed.
  • conical valve may also be not or not completely hollow. It may be constructed of or filled up with a compressible material.
  • valve according to the invention can in general be used in all cases in which a non-return valve system is required, for example in balloons, air-mattresses, skipperballs ana so on.
