Abstract
Abstract A dispenser package for viscous fluids comprising a container having one end open and provided with a piston and the other end closed by a compressible chamber defined by a plastic bellows that is deflected by movement of a plunger to dispense a portion of the viscous fluid from the container. The plastic bellows comprises a central tubular portion, a hub extending radially outwardly from the tubular portion, a plurality of circumferentially spaced panels extending transversely and radially from the tubular portion to a peripheral skirt extending axially away from the tubular portion. Integral circumferentially spaced ribs interconnect the panels. Alternate panels extend axially and radially upwardly away from the tubular portion while the remaining panels extend transversely and radially downwardly away from the tubular portion.
