Title:
【発明の名称】弾性絞りチューブ分与パッケージ
Document Type and Number:
Japanese Patent JP2825504
Kind Code:
B2
Abstract:
A resilient squeeze bottle dispensing package capable of dispensing viscous products without excessive air entrainment and belching on successive dispensing cycles. In a preferred embodiment, the viscous product (60) is preferably suspended inside a resilient squeeze bottle (12) in a thin flexible bag (10). The flexible bag (10) is secured about its perimeter to the interior of the squeeze bottle at its top (14) and approximately at its midpoint (11) to facilitate both complete emptying of product and desirable suckback characteristics when the opposed squeezing forces are removed from the resilient outer wall of the bottle. A suckback valve (30) is located between the dispensing orifice (20) in the shroud of the package and the flexible bag (10) to limit the amount of air which can enter the package through the dispensing orifice (20) at the conclusion of each dispensing cycle and to prevent slumping of viscous product remaining in the shroud (22) into the bottom of the flexible bag (10) between dispensing cycles. An air check valve (1) is preferably provided in the bottom (2) of the resilient squeeze bottle to facilitate a pressure buildup within the bottle when opposed squeezing forces are applied thereto.
