Definitions

  • a method of manufacturing a valve (1) for a container dispensing a pressurized fluid comprising a grommet (2) having a plug system (10) and defining a channel (3) with an inlet end (4) and an outlet end (5), a stem (6) slideably arranged in the channel (3), the grommet (2) comprising a first part (7) provided at said outlet end (5), and a second part (8) provided at said inlet end (4) wherein said first part (7) has a protrusion (11) within said second part (8), wherein the grommet is dual injected and characterized in that a multipurpose connection ring (19) is injected to the grommet during the same process.
  • the protrusion (11) of the first part (7) within the second part (8) of the grommet (2) prevents the fluid in the container from contacting the second grommet part (8), thereby avoiding sticking of the material against the inner side of the grommet (2) and hence avoiding blocking of the valve function. Additionally, the radially outwardly extending plug (10) and the protrusion (11) increase the resiliency of the grommet (2) of the valve (1).
  • the first part (7) of the grommet (2) is preferably manufactured in a hydrophobic thermoplastic material.
  • the first part (7) is made of a thermoplastic material, such as polypropylene or polyethylene, polyamide, ABS, POM or PET.
  • the material can be strengthened with reinforcing additives such a s glass fibre.
  • the second part (8) of the grommet (2) is injection molded over and along the first grommet part (7). In this way, adhesion between the different grommet parts (7) and (8) is increased and optimized.
  • the protrusion (11) of the first part (7) in the second part (8) of the grommet provides additional sealing and safety.
  • the second part (8) of the grommet (2) is injection molded along and under the first part (7) and at the sealing surface (13) pressed against the rim (30) of the container dome (9), providing a second sealing function.
  • the second part (8) of the grommet (2) is made of a resilient material, a good sealing can be obtained between the container dome (9) and the grommet (2).
  • the holes at the inlet (14a) of the dispensing channel (3) are located at a distance of the second grommet part (8), both in a closed and open position of the valve (1), the fluid in the container will not contact the second grommet part (8), thereby avoiding sticking of the material against the inner side of the grommet (2) and hence avoiding blocking of the valve function.
  • the second part (8) of the grommet (2) preferably is dual injection molded onto the first part (7) of the grommet (2) of the container dome (9) via a number of injection axes starting from the grommet (2).
  • the second (8) part of the grommet (2) is fastened over the rim (30) of the container cup (9).
  • the safety is increased.
  • detachment of the valve (1) from the container dome (9) is hence prevented.
  • the adhesion surface between the first (7) and the second (8) part of the grommet (2) is substantially increased.
  • thermoplastic multipurpose connection ring (19) an intermediate connection part for easy mounting on the foam applicator, illustrated in figure 1 .
  • the presence of an external thread (21) assures easy outside mounting of the foam applicator on the thermoplastic multipurpose connection ring (19).
  • the valve (1) comprises a radially outwardly extended plug system (10) which offers additional safety.
  • the plug system (10) is designed as two legs (40) which may be clamped against the inside of the container's cup (9), as illustrated in figure 5.
  • the design of this preferred embodiment requires no mechanical clinching process to fasten the valve (1) to rim (30) of the container's dome (9), the valve (1) can thus be assembled without the use of a clinching equipment thereby simplifying production and reducing production cost. Additional sealing is obtained by the radially outwardly extending legs (10) of the first grommet part (7) abutting the container dome (9).
  • the aerosol valve (1) according to the invention can comprise a spring mechanism mounted in the first part (7) of the grommet (2) to assist the closing of the valve at filling (not shown in the figures).
  • the prior art grommets have been replaced by a grommet (2) comprising combination of a first part (7) having a protrusion (11) within a second part (8).
  • the protrusion (11) prevents the second grommet part (8) from contacting the content of the container. Further, the protrusion (11) increases the adhesion of the first (7) and second part (8) on the interface. Thereby, the need for an additional process step, such as laser welding to join both parts together is avoided.
  • the valve (1) further needs to be moisture resistant. Therefore, the first part (7) of the grommet (2) is preferably made of hydrophobic thermoplastic material. Since the chemical components present in the container are moisture sensitive and react with moisture and/or gas to form the final polymer, it should be acknowledged that any contact with ambient moisture is to be avoided in order to prevent the forming of the final polymer inside the can or vessel. 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. Water penetration that is causing stickiness and blockage of the valve is hence inhibited.
