Abstract: A device for dispensing a fluid, including a bottom part having a bottom wall; a pocket having an interior volume arranged to contain the fluid; a pressing surface arranged to, under the exertion of pressure, reduce the interior volume of the pocket; a feed orifice arranged to feed the fluid to inside the pocket; and a bottom dispensing orifice arranged to release fluid inside the pocket. The device may include a cap, preferably rotating between closed and open positions, which is formed in a one-piece of the pocket and an outlet orifice from which fluid goes to the exterior of the device, and/or means to facilitate priming of the device when the pocket is initially filled at least partially with gas or air, and an outlet.

Abstract: A pump for dispensing a fluid, has a pump head, a piston with a piston body, a pump chamber provided by a pump chamber part, an inlet valve and an outlet valve. The piston body is moveable relative to the pump chamber. The piston body is tube-like, providing a channel for delivering the fluid from the pump chamber via the outlet valve to an outlet opening in the pump head. The outlet valve is a valve body cooperating with a sealing rim formed by an opening in an outlet channel of the pump head. The piston body has a sealing lip for with an inner surface of the pump chamber body. The pump head is moveable relative to the piston body providing an opening stroke for the outlet valve, wherein the valve body moves axially in the opposite direction into a part of the outlet channel above the valve body.

Abstract: A spray pump comprising a small piston and an upper pump rod with a liquid accumulation cavity is provided. The upper pump rod is provided with a liquid discharge hole communicates with the liquid accumulation cavity, and the small piston is provided with a sealing column for sealing the liquid discharge hole. A central column is provided with an ejector rod extending into the liquid discharge hole, and a liquid flow gap is disposed between the ejector rod and the liquid discharge hole. A central hole communicates with the liquid discharge hole is disposed at a central part of the central column, and a press head with a lower part being fixed with the central column. A press plate is fixed with the upper pump rod, and a press gap is disposed between an upper side of the press plate and a lower side of the press head.
