Abstract
A fill valve assembly for use in association with a filler device comprising an outer housing, a product dispensing member, a displaceable piston and a seal member. The product dispensing member is associated with the outer housing. The displaceable piston is displaceably positioned within the outer housing. The seal member is fixedly associated with the displaceable piston at one end thereof, and at least one of the outer housing and the product dispensing member, at another end thereof. The seal member is capable of maintaining fixed association throughout displacement of the displaceable piston, such that isolation of outer housing and the product dispensing member can be maintained without the use of seals having slidable engagement.
