A liquid dispensing apparatus comprising: a dispensing nozzle, end cap housing, lock-out mechanism, and dosage collar, wherein the lock-out mechanism is configured to prevent additional actuation of the dispensing nozzle and the dosage collar is configured to determine how far the dispensing nozzle may travel without resetting, which may allow the user to dispense a specific dosage of material to be dispensed via the dispensing nozzle.

A pump dispenser where the pump assemblies does not require disassembly to be recycled in current recycling streams. The pump assembly can include a plastic spring that does not lose stiffness over time and does not interact with the liquid product.

A universal closure for a dispenser is contemplated. The closure seals to the container neck along three separate surfaces with sufficient force to enable the use of lockdown and/or anti-rotational features to secure the dispenser for e-commerce shipments. Provision of frictional projections secures a sufficiently tight fit between the container neck and the body insert of the closure so as to eliminate the need to force separate engagement features on the container itself.

The invention pertains generally to an improved fluid dispensing device, particularly a dispensing device which employs at least one hemispherical domed cannister source of reactants and which uses a color-changing dispensing plastic tip to inform the end-user if the reactants are at a proper use temperature.

A dispensing pump capable of withstanding the rigors of “e-commerce” shipping conditions is described. The pump dispenser is integrated with the container's closure. The pump includes a lock-down mechanism to prevent the pump actuator from extending during shipment, while a vented chaplet and an optional beaded seal proximate to the dip tube connection ensure that fluid cannot leak out of the container or the pump.

The present invention concerns a device (1) for dispensing a fluid (L), suited to be coupled with a container (C) holding said fluid (L). The device (1) comprises a collapsible chamber (6) suited to draw, contain and dispense an amount of said fluid (L) and at least partially delimited by a deformable membrane (10) suited to be squeezed to dispense at least one portion of said amount from the collapsible chamber (6). The device (1) comprises locking means (50, 52, 56) suited to maintain the deformable membrane (10) in a fixed squeezed position and release means (80, 84a, 84b, 86a, 86b) suited to release the deformable membrane (10) from the fixed squeezed position.

A fluid dispenser includes a ring nut to be screwed on a bottle neck and including a shoulder and a collar extending in elevation from the shoulder. It also includes a dispensing head including a central portion, a spout designed to dispense the fluid contained in the bottle and a protective skirt extending to contain the collar of the ring nut. The protective skirt extends close to a peripheral portion of the shoulder and, in a closed configuration of the dispenser, has a safety distance from the shoulder. The dispensing head includes a cylindrical crown shaped to form a toothed profile and located between the protective skirt and the central portion. The ring nut collar includes gripping elements with a longitudinal extension and the toothed profile engages the gripping elements when closed. The toothed profile and the gripping elements are shaped to allow reciprocal rotation of the dispensing head.

Pump dispenser comprising a pump and a container for liquid to be dispensed, the pump comprising a pump body mounted in the neck of the container and a plunger reciprocable relative to the pump body to alter the volume of a pump chamber defined in the pump body and having an inlet and an outlet, the outlet leading through an outlet passage to a discharge opening. The pump cylinder body is retained at the container neck. A vent is provided in the cylinder body wall adjacent the neck edge. A vent block ring is disposed in the cylinder body adjacent the vent, and is moveable between blocked and unblocked positions relative to the vent. The vent block ring has an integral upward projecting formation which is engaged by part of the plunger in a locked-down position of the plunger, so that when the plunger is locked down the vent block element blocks the vent, while in a relatively extended position of the plunger the vent block element is in the unblocked position.

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 body cylinder and providing an external collar through which the plunger stem operates. The body insert has a lock-down thread to lock down the plunger for shipping. The insert also has an undulating annular vent-control bead extending right round its cylindrical outer surface, engaging the cylinder wall with interference for either blocking or unblocking the vent opening, according to whether the vent-control bead lies above or below the interior vent opening, by rotation between the body cylinder and body insert. The rotation can be driven by rotation of the plunger head, which makes a catch engagement with the top of the body insert. Blocking the vent during shipping reduces leakage.

Locking features of a pump system may include projections and corresponding features on a piston stem and lock cylinder of a pump system such that the features are configured to require an increased amount of force to rotate and unlock the piston stem from the lock cylinder.
