WIPO Patent Application WO/2016/062716
Kind Code:
A3
Abstract:
A dispenser for dispensing a flowable product from a container has a pump module (2) mounted on the container (1) at an opening thereof. The pump module includes a pump body, which defines a pump chamber and a pump chamber inlet for product to flow from the container interior into the pump chamber. A pump actuator (4) is operable in a pumping stroke relative to the pump body to vary the volume of the pump chamber and dispense the product. The pump includes a movable body portion (3) which is operable in a displacement stroke into the container. The movable portion has a displacement body (34) with a product-engaging face directed onto an interior product space of the container upstream of the pump chamber inlet, to assist priming. Below this a disrupter member (6), a grid of narrow bars, projects to penetrate the product.
