    • A liquid dispensing pump is provided with a supply container venting system and a shipping seal. The pump device includes an upper and lower housing which are axially movable relative to each other between open and closed shipping seal positions. The dispensing pump includes a collapsible pump chamber with at least one shipping seal functional element integral with the chamber. The pump includes actuation elements which cooperate to prevent pump actuation when the shipping seal is closed. The pump may also include a tamper evident device to prevent pump actuation prior to tamper evident tab removal. The chamber may also include an integral valve which has the valve member biased against the valve seat. A supply container venting system for the pump comprises a resilient annular flange angled downward from the bellows at the liquid entry end. The annular flange presses against an interior surface of the lower housing to seal a supply container vent opening against communication with ambient air and moisture. The annular flange remains in contact with the interior surface until either a vacuum generated in the supply container by pumping fluid therefrom deflects the flange away from the interior surface or at least one lug on the upper housing contacts and deflects the annular flange when the upper housing is actuated downward. A wiper extends from the lower housing in contact with the telescopingly engaged upper housing to further minimize any moisture entry between housings that could accumulate and inadvertently pass into the supply container.
    • 液体分配泵设置有供应容器排放系统和运输密封件。 泵装置包括上和下壳体,它们可以在打开和关闭的运输密封位置之间相对于彼此轴向移动。 分配泵包括可折叠泵室,其具有与腔室一体的至少一个运输密封功能元件。 泵包括致动元件,其协作以在运输密封件关闭时防止泵致动。 泵还可以包括防篡改的装置,以防止在篡改明显的突片移除之前的泵致动。 腔室还可以包括具有阀构件偏压抵靠阀座的整体阀。 用于泵的供应容器排放系统包括从液体入口端处的波纹管向下倾斜的弹性环形凸缘。 环形凸缘压靠下壳体的内表面以密封供应容器通风口,以防止与环境空气和湿气相通。 环形凸缘保持与内表面接触,直到通过泵送流体在供应容器中产生的真空将凸缘远离内表面偏转,或者上壳体上的至少一个凸耳接触并偏转环形凸缘,当上壳体 被向下致动。 擦拭器从下壳体延伸,与可伸缩接合的上壳体接触,以进一步最小化壳体之间可能积聚并无意地进入供应容器的任何水分进入。

    • A collapsible pump chamber is provided which includes several functional elements of a pump device. For example, the collapsible pump chamber may be a bellows which includes a functional element of an outlet vane, a functional element of a biasing feature, and a functional element of a spin chamber. Consequently, a functional element of all of the downstream functions are incorporated into the bellows. This can significantly reduce costs; due to reduced tooling, and assembly, for example. Dunnage means is provided for occupying volume within the collapsible pump chamber to improve pump priming. The dunnage means may be free floating or associated with the inlet valve. A process for severing the functional element of the outlet valve, the functional element of the biasing feature, and the functional element of a spin chamber from the collapsible pump chamber during assembly.

    • A collapsible pump chamber, e.g., a bellows, for use with a liquid dispensing pump device is provided. The collapsible pump chamber includes a collapsing side wall which defines an internal volumetric portion of the pump chamber. The collapsing side wall has a structure which collapses in a predetermined pattern as the pump device is actuated. For example, the predetermined pattern of collapse could result in an initially relatively small volumetric change in internal volume per given stroke length followed by an increased volumetric change in internal volume per given stroke length. Thus, the pump device would initially provide very good control over the amount of product is dispensed; giving precise control during a partial actuation. However, the same pump device would also be capable of delivering a large volume of product during a complete actuation.
    • 提供了一种与液体分配泵装置一起使用的可折叠泵室,例如波纹管。 可折叠泵室包括限定泵室的内部体积部分的塌陷侧壁。 塌陷侧壁具有当泵装置致动时以预定图案塌缩的结构。 例如,预定的塌缩模式可以导致每给定行程长度的内部体积的初始相对小的体积变化,随后是每给定行程长度的内部体积的增加的体积变化。 因此,泵装置最初将提供对分配产品量的非常好的控制; 在部分启动期间提供精确的控制。 然而,相同的泵装置也将能够在完全致动期间输送大量的产品。

    • A method for stripping an open ended bellows part from an injection mold has as a first step the injection molding of a bellows part. The bellows part has a resilient portion located between a core pin and a first split cavity and a substantially rigid portion located between the core pin and a second cavity. The substantially rigid portion has a first open end and an external undercut portion, and the resilient portion of the bellows part has an inner surface and a second open end. The first split cavity opens laterally to permit the resilient portion of the bellows part to be stripped from the core pin. Compressed gas passes through the core pin to the inner surface of the resilient portion of the bellows part while both open ends of the bellows part are closed off by the second cavity and the core pin. As the cavity and core portions of the mold separate, the second cavity grips the undercut portion of the substantially rigid portion of the bellows part, thereby pulling the resilient portion of the bellows from the core pin while compressed gas maintains the resilient portion expanded. Finally, the second cavity either opens or has a stripper rod to disengage the undercut portion of the substantially rigid portion of the bellows part so that the bellows part may be ejected from the injection mold.
    • 用于从注射模具剥离开口波纹管部件的方法作为第一步骤是将波纹管部件注射成型。 波纹管部分具有位于芯销和第一分裂腔之间的弹性部分和位于芯销和第二腔之间的基本上刚性部分。 基本刚性部分具有第一开口端和外部底切部分,并且波纹管部分的弹性部分具有内表面和第二开口端。 第一分裂腔横向打开以允许波纹管部分的弹性部分从芯销上剥离。 压缩气体通过芯销穿过波纹管部分的弹性部分的内表面,同时波纹管部分的两个开口端被第二腔和芯销封闭。 当模具的空腔和芯部分离时,第二腔夹住波纹管部分的基本刚性部分的底切部分,从而在压缩气体保持弹性部分膨胀的同时从波纹管拉出波纹管的弹性部分。 最后,第二腔体打开或具有剥离杆以脱离波纹管部分的基本上刚性部分的底切部分,使得波纹管部分可以从注射模具中弹出。
