    • The dispenser is for dispensing viscous products, has an ergonomic shape, and an automatic closure. The closure opens promptly upon initiation of an actuator and before the flow of viscous product from the dispenser. Further, the closure closes the dispenser outlet at the end of the return of the actuator to its rest position. Further, an outlet valve from a pump chamber remains open as an inlet valve to the pump chamber opens. This causes a suckback of viscous product near the dispenser outlet to flow into the dispenser. The automatic closure does not close as dispenser outlet until the suckback of viscous product has occurred. The automatic closure also functions as a knife or blade to assist in cutting the viscous product to maintain cleanliness and hygiene of the package.
    • 分配器用于分配粘性产品,符合人体工程学的形状和自动关闭。 在启动执行机构并在粘性产品从分配器流出之前,该盖子立即打开。 此外,在致动器返回到其静止位置的结束时,闭合件关闭分配器出口。 此外,当泵室的入口阀打开时,来自泵室的出口阀保持打开。 这导致在分配器出口附近的粘性产品的回吸流入分配器。 自动关闭不会作为分配器出口关闭,直到发生粘性产品的回吸。 自动关闭还用作刀或刀片,以帮助切割粘性产品以保持包装的清洁和卫生。

    • There is disclosed a closure comprised of a valve, a base unit and an upper unit. The base unit has a base surface with a peripheral skirt. The base surface has an aperture with a cylindrical section extending above and below the base surface. The cylindrical section has an aperture therethrough. The upper unit has an upper surface and an aperture adapted to align with the aperture of the cylindrical section of said base unit. The upper unit has a lid to cover the apertures in the base unit cylindrical section and the upper unit. A lid inner top surface has two projecting seals, one to maintain the valve closed when the lid is closed and the other to provide a seal when the lid is closed. and a latch mechanism attaches the base unit to the upper unit. A preferred latch mechanism comprises a projection and an interfitting recess, one being on the base section and the other on the upper section. The lid top surface preferably has an essential horizontal top surface. In a preferred embodiment the valve is a polymeric valve located in the aperture between the base unit and the upper unit and held in place by contact with both the base unit and the upper unit. The rheology of the product in the container and the characteristics of the valve are coordinated so that the product will be fully contained by the valve regardless of the orientation of the container, including being inverted.
    • 公开了一种由阀门,基座单元和上部单元构成的封闭件。 基座单元具有带有周边裙部的基面。 基面具有孔,其具有在基底表面上方和下方延伸的圆柱形部分。 圆柱形部分具有穿过其中的孔。 上部单元具有适于与所述基座单元的圆柱形部分的孔对准的上表面和孔。 上部单元具有覆盖基部单元圆柱形部分和上部单元中的孔的盖。 盖内表面具有两个突出的密封件,一个用于在盖子关闭时保持阀门关闭,另一个在盖子关闭时提供密封。 并且闩锁机构将基座单元附接到上部单元。 优选的闩锁机构包括突起和相互配合的凹槽,一个在基部上,另一个在上部。 盖顶表面优选具有基本的水平顶面。 在优选实施例中,阀是位于基座单元和上部单元之间的孔中的聚合物阀,并且通过与基座单元和上部单元两者接触而保持就位。 容器中的产品的流变性和阀的特性被协调,使得产品将被阀完全容纳,而不管容器的取向如何,包括倒置。
