Definitions

  • the present invention concerns a design improvement to a tilting/gun valve, more particularly regarding the problem of sticking/blocking.
  • the tilting valve will be used for dispensing moisture sensitive products such as one or two component polyurethane (PU) foam system, adhesives, sealants, etc or non moisture sensitive products such as tooth paste contained in a pressurized can or vessel.
  • the product may have a high viscosity or a low viscosity.
  • tilting/gun valves relevant for the present invention is used for more than 25 years in order to dispense the content of an aerosol can.
  • a typical tilting valve is made of a cup, a stem with a base and a gasket/seal called the grommet and made of an elastomer polymer.
  • This elastomer polymer is a hydrophobic or hydrophylic, thermoplastic or non thermoplastic elastomer polymer.
  • the grommet By tilting the hollow stem, the grommet will no more be in a sealing configuration and the valve therefore opens and delivers the vessel's content in an easily controllable way .
  • E xamples of elastomer polymers suitable for a grommet are : styrene-butadiene, butylene-styrene, silicone rubbers, isopropyl ether (Kraton, Shell) , chlorinated polyethylene ( Tyrin, Dupont De Nemours) , epichlorhydrin homopolymers or copolymer, ethylene propylene (Nordel, Dupont de Nemours), fluoroelastomers (Viton, Kalrez, Du pont de Nemours), alcryn MPR (chlorinated olefin interpolymer alloy) , Santoprene and Trefsin (Advanced Elastomer Services, Exxon)
  • a tilting valve comprising a cup, a stem with an enlarged circular base end extending perpendicularly and, therebetween, a grommet made of an elastomer polymer wherein the grommet is provided with a flat inner surface extending essentially on all the flat upper surface of the enlarged base of the stem to secure the sealing effect.
  • a flat configuration according to the invention allows this hard jacket to be formed away from the stem shaft. Jacket formation at the outer part of the grommet is no longer a problem.
  • the grommet and stem sealing surface is increased and the contact surface between the reactive component and the grommet is reduced.
  • the creep of the valve is drastically reduced.
  • Fig. 1 illustrates a standard tilting/gun valve
  • Fig. 2 is a sectional view of an embodiment of a new design according to he invention.
  • Fig. 3 shows various other embodiments of a valve according to the invention
  • Fig. 4 shows sectional view of variants of the grommet.
  • Fig. 5 shows three possible shapes of the bottom of the stem for a valve according to the invention.
  • F ig. 1 illustrates in a sectional view an example of a traditional tilting/gun valve showing basically a cup 5, a stem 10 with a base 11 and a gasket/seal 12.
  • the inner gasket/seal 12, called the grommet is made of an elastomer polymer.
  • This elastomer polymer is a hydrophobic or hydrophylic, thermoplastic or non thermoplastic elastomer polymer.
  • the grommet By tilting the hollow stem 10, the grommet will no more be in a sealing configuration and the content will have access to the hole 13 located at the bottom of the stem, above the base 12.
  • the valve therefore opens and delivers the vessel's content in an easily controllable way.
  • FIG. 2 This new design is illustrated in Fig. 2 wherein there is shown in elevation a sectional view of a valve according to the invention in closed and open position.
  • the opening of the valve is by pushing the stem (gun type action, Fig. 2b) or by tilting the stem (Fig. 2c) .
  • the measurements on the valves are done on valves in pressureless condition.
  • Condition 2 0 ⁇ Ratio 1 x H ⁇ 2.8 or Condition 3 : 0 mm ⁇ Ratio 2 x H ⁇ 5
  • the tilting valve of the invention has typical values for Ratio 1 of 0.60 and 1.20 for Ratio 2, where the typical values for the traditional valves ranges for Ratio 1 from 0.7 to 0.9 and 1.4 to 1.6 for Ratio 2.
  • the calculated area of the grommet in contact with the product, for the usual size valves is advantageously between 150 and 250 mm2 , but may be less than 150, even less than 100 mm 2 , where for traditional tilting valves the contact area lies between 200 and 300 mm 2 .
  • the grommet and stem have therefore a flat design that is to say flat surfaces are provided at the lower end of the grommet and stem and such surface will substantially cooperate for sealing the content of the valve. Further examples are shown in Fig.3.
  • Fig. 5a shows a stem with a bottom circular disc having a slight curvature on the upper surface.
  • the outer circular parts of the discs of fig.5b and 5c show an extension
  • the grommets can have the same shape in the outer circular disc as shown in fig. 4a, fig. 4b and fig. 4c. Any combination stem/grommet described above is possible.
  • an insert of any kind of shape with a higher or lower hardness than the basic grommet material integrated in the bottom section of the grommet can be placed in the bottom section of the grommet, the above mentioned conditions are not necessarily applicable and even the current grommet design can be used. This is illustrated in Fig. 6.
  • the grommet of the invention may further be treated with a chemical coating or may be coupled to a spring arrangement to compensate for possible inferior "snappy properties" of the grommet and thus the valve .
  • the coating treatment may be conducted either by spraying or immersion in the coating fluid or by plasma treatment.
  • the coating may be reactive or non-reactive. A significant improvement in overall properties of the valve according to this invention is noticed.
  • the aerosols or vessels according to the invention can be stored vertically, horizontally and may be shaken every day. It has been found that the valves designed and treated according to the invention are still working and no leakage, sticking or blocking of the valve is encountered even after 12 months at 45°C and 90% RH (Relative Humidity) .

Abstract

L'invention concerne une amélioration apportée à la conception d'une soupape canon/basculante, plus particulièrement au problème d'adhérence/blocage. La soupape comprend une coupelle (5), une tige (10) munie d'une extrémité à base circulaire agrandie (21) perpendiculaire; et, entre la coupelle et la tige, un joint annulaire (22) en polymère d'élastomère. Le joint annulaire (22) présente une surface inférieure plate s'étendant principalement sur toute la surface supérieure plate de la base agrandie de la tige pour renforcer la fonction d'étanchéité. La hauteur (H) du joint annulaire (22), sous la coupelle, est inférieure à 4 mm.
