A dispenser for dispensing a flowable product from a container has a pump module mounted on the container 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 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 which is operable in a displacement stroke into the container. The movable portion has a displacement body 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, a grid of narrow bars, projects to penetrate the product.

An all plastic compression spring assembly includes a slotted tubular spring element formed from a tensile polymer material and first and second loading cones received at opposing first and second ends of the slotted tubular spring element. The loading cones are axially compressible toward each other within the slotted tubular spring element whereby the slotted tubular spring element radially expands in tension to create an opposing radial contraction force, and in turn, an axial extension spring force. When released, the spring element elastically returns to its normal at rest shape, returning the cones to their normal at rest positions.

A trigger type liquid ejector includes an ejector main body having a vertical supply pipe, an ejection barrel, a trigger mechanism having a main piston and a main cylinder, a reservoir cylinder, a reservoir plunger, a first check valve configured to block communication between a container body and the vertical supply pipe when the main cylinder is pressurized and allow communication when the main cylinder is decompressed, and a second check valve configured to allow communication between an ejection hole and the vertical supply pipe when the main cylinder is pressurized and block communication when the main cylinder is decompressed, and a communication path is provided between the main piston and the main cylinder and is configured to bring the main cylinder in communication with the container body when the main piston is moved to a position deviated rearward from a frontmost position.

A foam dispenser has a foam-generating pump (1) mounted on a container (100) to hold liquid. The pump (1) has a liquid intake conduit with a ball valve (27) and an air intake conduit (45) provided partly by a jacket component (4) fitting around the pump body (2) with clearance. The pump has structure defining a mixing zone (50) for mixing air and liquid, a foam chamber (28) for holding foam received from the mixing zone, and a discharge conduit leading from the foam chamber to a discharge outlet (36). The mixed air and liquid pass through a permeable foam regulator mesh (54). One or more air inlets (47) lead into the mixing zone (50) from the air intake conduit (45). A liquid inlet in the form of a restricted jet orifice (89) leads into the mixing zone (50) from the liquid intake conduit, upstream of the inlet ball valve (27). A regulator mesh (53) is also provided between the liquid inlet and mixing zone.

Disclosed is a lotion pump comprising: a pressing head (10) comprising a pressing head body (11); a cylinder (30); a cylinder head connected to an upper end of the cylinder and having an inner hole; a threaded sleeve (20) connected to the cylinder head; and a piston rod (40), with one end being connected to the pressing head body, and the other end extending into the cylinder and being provided with a piston (50). The lotion pump further comprises a neck sleeve (13) formed on the pressing head body. A first slope is formed on a lower portion of the neck sleeve, and a second slope matching the first slope is formed on the top of the threaded sleeve. The lotion pump having the foregoing structure can ensure the sealing against the outside when the lotion pump is in a standby state or an upper locked state, so as to prevent water from seeping into the lotion pump during bathing.

A trigger-type ejector includes: a pressure storage chamber formed in a nozzle head and communicating with a flow path through a communication hole; a pressure storage plunger including a large-diameter pressure receiving portion opposite a small-diameter pressure receiving portion and being movable between a close position where an ejection hole is closed and an open position where the ejection hole is opened; and a biasing member disposed in the pressure storage chamber and biasing the pressure storage plunger toward the close position, the trigger-type ejector being configured such that, when a pressure of a liquid in the pressure storage chamber becomes equal to or greater than a predetermined value, the pressure storage plunger moves from the close position to the open position against a biasing force of the biasing member and thus a liquid in the pressure storage chamber is ejected from the ejection hole to the outside.

Described is a dispenser for dispensing a fluid contained in a plastic bottle, including a ring nut having a cylindrical conduit for sucking the fluid; a concertina-like deformable element including side walls defining a dosing chamber; a ring identifying with the ring nut a locking system defining an operating and non-operating configurations; a dispensing head, which can be pressed by a user and having a collection chamber collecting the fluid flowing from the dosing chamber through a central opening of the ring; first and second shutoff elements defining, respectively, a check valve at the inlet and a check valve at the outlet of the dosing chamber; a locking element interfering with at least one between the first and the second shutoff elements to lock it in the fixed position and thereby occlude the suction conduit and/or the central opening in a stable manner at least in a dispensing configuration.

A manually operated pump including: an inlet one-way valve; a pump chamber downstream of and in fluid communication with the inlet one-way valve; a piston interior to the pump chamber and slideably engaged with the pump chamber; an actuator engaged with the piston or the pump chamber; a block thermoplastic elastomeric spring engaged with the actuator to move the actuator as the block thermoplastic elastomeric spring relaxes; and an optional outlet one-way valve downstream of and in fluid communication with the pump chamber.

A device (1) for dispensing a fluid substance (S) comprising a cup-shaped body (3) equipped, at the bottom (2) thereof, with a first valve element (4) which intercepts a passage (5) for the suction of the said fluid substance into a compression chamber (6), a cup-shaped body (2) closing element (7) equipped with a window (8), a dispensing button (15), and a shaped element (9) functionally coupled to the dispenser button (15) for the movement thereof into the cup-shaped body (3), the shaped element (9) comprising a flange portion (10) configured to slide along an internal wall (3A) of the cup-shaped body, a deformable portion (11) extending from the flange portion (10) which is bell-shaped when non-deformed, the deformable portion (11) being elastically deformable, the said deformable portion (11) determining, at least together with a part of the cup-shaped body (3), the said compression chamber (6).

A pre-compression pump includes a main body, a first piston assembly movably mounted in the main body, a head assembly on a top of the first piston assembly, a second piston in the first piston assembly, and a second spring supported between the second piston and the first piston assembly. A water storage sump is disposed between the main body and the first piston assembly. A water outlet channel is disposed in the inner part of the first piston assembly. The water outlet channel is connected to the water storage sump and a nozzle of the head assembly. The second piston has an ejector pin portion for sealing the water outlet channel.
