摘要：A resilient squeeze bottle dispensing package capable of dispensing viscousproducts without excessive air entrainment and belching on successive dispensing cycles.In a preferred embodiment, the viscous product is preferably suspended inside a resilientsqueeze bottle in a thin flexible bag. The flexible bag is secured about its perimeter tothe interior of the squeeze bottle at its top and approximately at its midpoint tofacilitate both complete emptying of product and desirable suckback characteristicswhen the opposed squeezing forces ae removed from the resilient outer wall of thebottle. A suckback valve is located between the dispensing orifice in the shroud of thepackage and the flexible bag to limit the amount of air which can enter the packagethrough the dispensing orifice at the conclusion of each dispensing cycle and to preventslumping of viscous product remaining in the shroud into the bottom of the flexible bagbetween dispensing cycles. An air check valve is preferably provided in the bottom of theresilient squeeze bottle to facilitate a pressure buildup within the bottle when opposedsqueezing forces are applied thereto.
