The invention concerns an elastic element (100) made of a plastic material for a device (1) for dispensing fluids (L), comprising a tubular body (129) that develops around a main longitudinal axis (X), comprising a main portion that develops according to a spiral-shaped pattern and extends longitudinally between a first end portion (100a) and a second end portion (100b) opposite the first end portion (100a). One of the first and second end portions comprises a first projection (151) extending from the internal surface of the tubular body (129) towards the inner space defined by the tubular body (129). The invention furthermore concerns a method for making an elastic element (100) through an injection moulding process, a mould (200) for making an elastic element (100).

A dispenser pump has a plunger operable in a body including an outer cylinder body having a vent opening in its sidewall and a body insert fitting into the top of the outer body and providing an external collar through which the plunger stem operates. The body insert has lock-down threads to lock down the plunger for shipping. The insert also has formations for blocking or unblocking the vent opening by rotation between the outer body and body insert, driven by rotation of the plunger head which makes a catch engagement with the top of the body insert. This plunger head rotation is the locking or unlocking action for the plunger lock-down. Blocking the vent during shipping reduces leakage.

The disclosure discloses an all-plastic pump including an outer cover, a plastic spring, an inner cover and a pressing head. An accessory cavity is defined in the outer cover, and a conveying hole is formed inside the accessory cavity. The plastic spring surrounds the conveying hole, a plurality of supporting rods are circumferentially disposed on an inner wall of the plastic spring, and the plurality of supporting rods are connected to a baffle. The inner cover surrounds the plastic spring, a stop tube is disposed inside the inner cover, penetrates into a space defined by the supporting rods, and is in sealing abutting connection with the baffle. The pressing head is installed in the accessory cavity in a pressable manner, and provided with a discharging hole, a pressing sheet and a conveying pipe. The pressing sheet is opposite to an end face of the plastic spring, the conveying tube is inserted into the stop tube, the conveying tube is in connection and communication with the discharging hole, and pressing of the pressing head is configured to push the pressing sheet to urge the plastic spring so as to separate the baffle and the stop tube from each other. Therefore, through the solution, a pump head can still be opened and closed, a metal spring is replaced with the plastic spring, and the problem that an existing pump head is inconvenient to directly recycle is practically solved.

Disclosed in the invention is an all-plastic pressing pump comprising: an actuator, an insert, a housing, a container cap, a piston guide, a pump ball, a spring, and a protective cover, made of plastic. The lower end of the piston guide is provided with a slidable sealing part that is inserted into the housing and slidably and sealing connected to the inner wall of the housing. The container cap has a central hole for the piston guide to pass through. A conical frustum sealing part is provided on the piston guide above the slidable sealing part, and the conical frustum sealing part forms a sealed connection with the side wall of the central hole when it bounces up. An air replenishment channel is disposed between the housing and the container cap. A liquid outlet channel and a switch structure are disposed between the actuator and the piston guide, and the switch structure opens the liquid outlet channel when the actuator is pressed down and blocks the liquid outlet channel when the actuator bounces up. A guide sleeve is provided on the top of the container cap and is upwardly sleeved on the outer side of the actuator. An anti-off protrusion is provided at the upper end of the guide sleeve. The actuator is provided with an anti-off hook that is capable of being hooked on the anti-off protrusion. The spring is disposed inside the guide sleeve and is pressed between the top of the actuator and the top of the container cap. The spring is a plastic spring tube with open upper and lower ends and a sealed side, and the structure thereof is simple.

A push pump dispenser injects liquid within a cylinder portion from a nozzle portion by pushing down the finger putting portion located above a grip portion in a state where the grip portion has been grasped by a user. A finger abutting portion of the grip portion is located behind a power point of the finger putting portion.

A multi reservoir dispenser includes a first reservoir for holding a first fluid and a second reservoir for holding a second fluid. The dispenser further includes a pump mechanism that includes a pivotable trigger and a first plunger cavity that is disposed along the first flow path for receiving the first fluid and a second plunger cavity for receiving the second fluid. The pump mechanism also includes a first plunger that is disposed and movable within the first plunger cavity and a second plunger that is disposed and movable within the second plunger cavity. A selectable actuator is movable between: (a) a first position in which only the first plunger of the pump mechanism is actuated for discharging only the first fluid through a first orifice of a nozzle by causing the first fluid to flow along a first flow path; and (b) a second position in which only the second plunger of the pump mechanism is actuated for discharging only the second fluid through a second orifice of the nozzle by causing the second fluid to flow along a second flow path.

A pump engine assembly includes an output cylinder that may be customized to include a stop portion limiting the stroke of a piston to produce a particular output such that customized pump systems may be produced from similar parts with the exchange of only a single partthe output cylinder, and wherein movement of a fluid lock in a product chamber creates a suck-back feature capable of pulling product away from a dispensing head opening.

A dispensing pump includes a spring assembly and a locking arrangement to prevent the dispensing head from being deployed and/or actuated during shipment, stocking and pre-purchase handling. The dispensing pump includes a pump base, and a dispensing head having a piston stem. The spring assembly includes a slotted tubular spring element and first and second loading cones received at opposing ends of the slotted tubular spring element. Various locking arrangements may include interacting rotatable lugs provided between the dispensing head and the pump base, snap beads to retain the piston and dispensing head in a secured shipping position, and recyclable locking rings disposed between the dispensing head and pump base which prevent an active dispensing head from being actuated.

A trigger-type liquid dispenser that, even when lateral force is applied to a trigger, prevents liquid leakage. The trigger-type liquid dispenser includes a pump, which includes: a cylinder, which includes an inner tubular wall and an outer tubular wall; a piston, which has a front-side end portion; a front-side sealing piece and a rear-side sealing piece; an outer-circumferential-side support portion; and an inner-circumferential-side support portion. The outer-circumferential-side support portion is provided with an annular cut-off portion, which forms a gap between the outer-circumferential-side support portion and an outer circumferential surface of the piston.
