Definitions

  • the present invention relates to a new valve stem for a pressurized fluid container, more particularly for one and two component polyurethane foam applications.
  • Sprayable foams are used for several industrial applications as well as by hobbyists.
  • One well known example of sprayable foam is polyurethane foam.
  • Polyurethanes are used in high resiliency flexible foam seating, rigid foam insulation panels, microcellular foam seals and gaskets, durable elastomeric wheels and tires, electrical potting compounds, high performance adhesives and sealants, Spandex fibres, seals, gaskets, carpet underlay, hard plastic parts, etcetera.

  • the polyurethane product is then forced by propellant pressure in the aerosol can to flow between the separated surfaces through the valve stem side lateral openings and up through the stem central bore to exit the aerosol valve to the area where the polyurethane foam is being applied.
  • Aerosol valves have been widely adopted, but many are known to have a problem of occasional valve sticking when used to dispense polyurethane aerosol foam.
  • Polyurethane foam after it is dispensed from the can and valve will of course desirably cure and harden.
  • small amounts of product which rests between the grommet and the stem base is also subject to curing and hardening and results in sticking of the stem base to the grommet and hence in failure of the valve operation.
  • moisture is present in the can, this curing will begin to occur in the can itself and can result in a stuck aerosol valve such as to render the purchased product useless to the consumer.
  • a source of moisture occurring in the aerosol can of the polyurethane product is believed to be environmental moisture in the air outside the can.
  • This moisture can permeate the grommet seal due to the portion of the grommet extending into the environment outside the can and mounting cup. Since a portion of the grommet seal also extends inside the can under the mounting cup, the permeated moisture can egress from the grommet inside the can to come in contact with the active ingredient of the polyurethane product inside the can. Thus, curing and hardening may begin inside the can resulting in the stuck aerosol valve and the failed product.
  • the invention is intended to provide a solution to the above problem of environmental moisture permeating the grommet seal and entering the can of polyurethane product.
  • the invention discloses an aerosol valve for dispensing polyurethane foam including a plastic liner shield to prevent environmental moisture permeating through the sealing grommet into the aerosol can to harden product and disable the valve.
  • the liner has an annular upper portion in the mounting cup channel for sealing to the can bead, an intermediate portion surrounding the grommet in the can, and a lower annular flange extending between the valve stem base and lower grommet surface.

  • the polyolefin is preferably a polyethylene.
  • the valve stem is made of PEGF.
  • glass-filled polyethylene valve stems show superior resistance to sticking over valve stems of other material, the production of a valve stem which additionally comprises glass fiber over the traditional stem material requires an additional amount of energy and is thus not ecological and more expensive.
  • Another drawback of a stem which is reinforced with glass fiber is that the production is not healthy, as glass fiber is harmful by inhalation or ingestion, and also via skin contact. Health effects from exposure to glass fibers can be different depending on the fiber size and type of exposure. Glass fibers have been found to cause skin, eye and upper respiratory tract irritation.

  • the present invention is directed to a valve stem comprising a hollow stem body having a first open end, and a second end closed by a stem base forming a flange, characterized in that at least the face of the flange adjacent said stem base comprises an additional layer.
  • the problem arises in pressurized dispensing containers where the product dispensed, such as PU foam, gets between the grommet and the valve stem, particularly the stem base.
  • the product dries or cures and creates a seal or adhesion between the outside of the valve stem and the grommet. When that occurs, it becomes difficult to displace the stem relative to the cup.
  • Such displacement of the stem is needed to allow the product inside the container to enter the orifices of the stem and thus for product dispensing.
  • the foam can harden against the stem base, which also causes failure of the valve function.
  • the stem base material is subject to swelling when it comes into contact with the product, causing loss of dimensional stability, gas loss and thus a decreased product shelf life.
  • the valve stem base can be protected with an additional layer.
  • the additional layer covers at least the face of the flange adjacent the stem base, which is in close contact with the grommet, whereby sticking of the product between the grommet and stem base is avoided.
  • the additional layer thus prevents sticking of the stem base when the PU foam cures or hardens between the stem base and the grommet which makes activation of the valve impossible.
  • the additional layer offers more resistance to stickiness than all other stems lacking an additional layer.
  • the additional layer further provides dimensional stability as the stem base is less prone to swelling. Dimensional stability and good closure between the stem base and the grommet reduces gas loss and thus increases the shelf life of the container containing the product to be dispensed.
  • the stem base comprises an additional layer on the face of the flange adjacent the stem base. More preferably, the stem base further comprises an additional layer at the face of the stem base opposite the stem body to further prevent curing of the product against the stem base. In another preferred embodiment of the present invention, the stem base comprises an additional layer covering the whole surface of the stem base external of the stem body, so that all contact of the stem base with the product is avoided. In this way, it is not possible that the foam cures out between the face of the flange of the stem base and the grommet and around the stem base, whereby activating the stem is made impossible.
  • the additional layer is preferably made of any of polyethylene (PE). This is a soft material but has good stickiness resistance qualities.
  • the stem base is preferably made of thermoplastic materials such as polyoxymethylene (POM), polybutylene terephthalate (PBT) or polyolefin material, such as polyethylene (PE) or polypropylene (PP). It is known that the adhesion between PE and PP is very good, so no moisture ingress is possible and thus the product can not stick between the different materials.
  • POM polyoxymethylene
  • PBT polybutylene terephthalate
  • PE polyethylene
  • PP polypropylene
  • the present invention is also directed to a valve comprising said stem and towards a container for dispensing a pressurized fluid comprising a valve with said valve stem.
  • the present invention is further directed to a method for producing said stem for valve by means of dual injection molding.
  • valve stem It is a related purpose of this invention to achieve the main object in an inexpensive fashion with a design which does not modify or compromise the dispensing operation of the container. Further, because no glass fiber is needed to avoid sticking and blocking of the valve function, the stem can be produced in a safe and healthy manner.
  • An advantage of the valve stem according to the present invention is that the valve stem and the additional layer can be integrally molded, preferably dual injection molded. The additional layer therefore eliminates the problem of valve sticking in a simple manner. In addition, it has been found that the stem base protects the valve longer times to initial sticking and thus longer times to valve failure.
