Definitions

  • the present invention relates to a new aerosol valve for a pressurized fluid container, more particularly for one component polyurethane foam applications.
  • a well-known application is sprayable foams used in both industrial applications and by hobbyists. As such, containers with sprayable foam can be exposed to rather extreme conditions in terms of temperature and pressure.
  • the new valve of the present invention overcomes the above mentioned drawbacks. In order to prevent the valve from detaching from the container due to overpressure, it is possible to increase the adhesion between the different grommet parts.
  • the valve according to the present invention is a valve for a container, the valve comprising a cup, a grommet defining a channel with an inlet end and an outlet end and a stem slideably arranged in the channel, whereby the grommet comprises at least two parts sealingly engaged, said first part having protrusion within said second part.
  • valve is safe and sufficiently resilient while equally being moisture resistant thereby avoiding stickiness and blockage of the valve.
  • the invention describes a valve comprising a plastic cup attached to the opening edge of a pressurized can, comprising a coupling device for a can adaptor of a dispensing unit.
  • the plastic cup further comprises a plastically deformable, particularly a clinchable, cylindrical pot wall.
  • the coupling device for the can adaptor is formed as an integral connection part. It made of plastics material and is attached via thin connecting webs to the outer edge of the pot wall of the valve head. A safety lip is provided to assist in withstanding pressure.
  • the coupling device of the invention comprises a safety lip to assist in withstanding pressure
  • the inside of the valve is not protected against rising pressure. If the pressure inside the can rises due to extreme conditions in terms of temperature and pressure, the grommet comprising different elements can loosen and the valve can detach from the container.
  • thermoplastic materials exhibit other inconveniences such as “creep”, which is a well known property of thermoplastic (TP) rubbers. This creep allows for the materials to deform and causes the grommet to detach from the cup when the container is put under extreme pressure.
  • the present invention provides a valve for a container dispensing a pressurized fluid and an assembly applied for dispensing of pressurized fluids with safety properties, high adhesion properties and sufficient resilience while avoiding the use of an embedding or molding step and avoiding the necessity of using of a spring.
  • valve for a container dispensing pressurized fluids which valve is moisture repellent and therefore will inhibit the water diffusion and/or absorption that is causing stickiness and blockage of the valve.
  • the present invention is directed to a valve for a container, said valve comprising a grommet having a plug system and defining a channel with an inlet end and an outlet end and a stem slideably arranged in the channel, whereby the grommet comprises at least two parts sealingly engaged, said first part having protrusion within said second part.
  • the present invention is directed to a valve ( 1 ) for a container, said valve ( 1 ) comprising a grommet ( 2 ) having a plug system ( 10 ) and defining a channel ( 3 ) with an inlet end ( 4 ) and an outlet end ( 5 ) and a stem ( 6 ) slideably arranged in the channel ( 3 ), whereby the grommet ( 2 ) comprises at least two parts ( 7 ) and ( 8 ) sealingly engaged, said first part ( 7 ) having protrusion ( 11 ) within said second part ( 8 ).
  • An advantage of a valve according to the present invention is that additional safety is provided by the design of the grommet. Due to the first part of the grommet having a plug system and protrusion within said second part of the grommet, the valve is prevented from detaching from the container dome ( 9 ) when overpressure occurs inside the container due to extreme conditions in terms of temperature and pressure
  • Another advantage of a valve according to the present invention is that by providing a first part of the grommet having protrusion within a second part of the grommet, additional resilience is provided. Also, by increasing the contact surface of the first arid second part of the grommet, additional adhesion and sealing is provided. Furthermore, the different parts of the hydrophobic grommet are dual injected. Due to the technique of injecting the different grommet parts, the adhesion between the first and second part of the grommet is guaranteed.

  • the protrusion ( 11 ) of the first part ( 7 ) within the second part ( 8 ) of the grommet ( 2 ) increases the contact surface of both parts and thus the sealing of both grommet parts ( 7 ) and ( 8 ).

Moisture diffuses via the valve system, more particular the rubber grommet in case of gun and tilting valves. Additionally, by means of the protrusion ( 11 ) of the first part ( 7 ) within the second part ( 8 ), any contact between the chemical components in the container and the second part ( 8 ) of the grommet is avoided.
