A dispenser for liquid to pasty substances has a dispenser head and a dispenser body. The dispenser head is movable relative to the dispenser body in a displacement direction for carrying out a pumping movement and is also rotatable relative to the dispenser body. The dispenser has a pump chamber having an inlet valve and an outlet valve. A dispensing tube is provided and is divided into two portions which can move relative to each other and which, as a result, can be moved into a closed position in which the substance cannot be dispensed and into an open position in which the substance can be dispensed. The portions, in order to change between the closed position and the open position, can be moved relative to each other without a relative movement in the displacement direction.

An article includes an adapter having a flow channel extending through it, where the adapter includes a base, a neck, a bendable segment attached to the base and neck and positioned between the base and neck, and a plunger attached to the neck or bendable segment and extending within the flow channel in the bendable segment.

A dispensing closure for a squeeze-type container produces a fan-type spray in a low pressure environment. The dispensing closure includes a closure body having an upper deck and a skirt depending from the upper deck. The skirt is configured and arranged to attach to a product container, such as a squeeze-type container. A flow conduit extends from an interior of the closure body and through the upper deck to provide a flow path from an interior of the closure to an exterior of the closure. The flow conduit has an entrance orifice and an exit orifice. The flow conduit has an inner wall extending between the entrance orifice and the exit orifice. The flow conduit and the closure body are integrally formed. The flow conduit includes a tip portion with an exit orifice defining a shape to provide a fan-type spray in a low pressure environment.

A fluid delivery system for dispensing fluid can include a dispenser, such as a trigger engine-type dispenser, configured to draw fluid up from a container. A nozzle assembly can include a nozzle, and a nozzle slide. The nozzle slide can be configured to slide and/or rotate relative to the shroud to provide different dispensing modes. In alternative examples, the nozzle can be configured to rotate in 30 degree increments relative to the shroud to provide the different dispensing modes or the nozzle assembly can include a nozzle extension, and the nozzle extension can be configured to rotate relative to the shroud to provide different dispensing patterns out of the nozzle. In another example a first nozzle can be configured to provide one or more dispensing modes, and a second nozzle can be configured to provide a different dispensing mode than the first nozzle. Methods of dispensing fluids and methods of assembling fluid dispensers are also disclosed.

A nozzle for a fluid delivery device includes a nozzle head. The nozzle head defines an inner head chamber for a fluid. The nozzle head has at least one nozzle opening through which fluid is configured to be selectively delivered from the head chamber to a target site during use of the device. The nozzle head is at least partially formed from a deformable material. The nozzle head is selectively deflectable between an opened condition in which the at least one nozzle opening is at least partially open to permit fluid flow therethrough and a closed condition in which the at least one nozzle opening is at least partially closed to restrict fluid flow therethrough.

The multi-nozzle multi-container fluid spray device includes multiple, for example, three, containers. Each container may hold a different liquid which the user may dispense simultaneously, in a desired combination, or individually. The containers are connected to each other and to a spray handle and spray head in a reversible manner. The spray head includes multiple nozzles, with each nozzle being designed to independently turn on, off, or to dispense a liquid spray at a desired density of liquid particles. The multiple pumps and hoses may be housed within the spray head. Each of the hoses extends from a single pump into one of the containers. Each pump is designed to dispense a liquid from one of the containers through a single nozzle. If a nozzle is turned off, the pump connected to that nozzle does not dispense liquid from the container with which it is connected.

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.

A trigger-type liquid dispenser includes a dispenser main body, pump, and nozzle. The body includes a fitted portion, which communicates with a delivery port. The nozzle includes a partition wall, which covers an opening end of the fitted portion and has a dispensing hole, and an outer circumferential wall. The nozzle is rotatable with respect to the fitted portion between an opened position, wherein the hole communicates with the port, and a closed position, wherein the hole is blocked. The outer circumferential wall includes a locking projection, in undercut engagement with a projecting portion, on an outer surface of the fitted portion, to hold the nozzle in engagement with the fitted portion. The locking projection, in an inner edge portion thereof, has a concave portion, wherein the degree of undercut engagement with the projecting portion is reduced when the nozzle is located between the opened and the closed position.

A discharge head for a fluid container, including a discharge opening and a switching valve which closes and opens a fluid path between the fluid container and the discharge opening. The discharge head has an inner component fixedly connected to a fluid store and an outer component movable relative to the inner component and non-separably connected thereto. The outer component is moved relative to the inner component between a first relative closure position and a second relative open position. The switching valve is opened and closed by movement of the inner component relative to the outer component, is closed in the first position and open in the second position. The inner and outer components are locked in the first position by a child-resistant mechanism, and displacement of the outer component from the first position into the second position is prevented in a locking position of the mechanism.

A trigger dispensing head for a dispensing device is provided. The trigger dispensing head has a frame, a manually operable trigger, a piston chamber, a piston, a dispensing duct, a suction duct, pre-compression valves, suction valves, a locking member and a nozzle having a gripping wall equipped with an actuation compartment and an interference element. The nozzle is movable between an opening position, in which the locking member is freely movable in the actuation compartment, and a closing position, in which the locking member engages the interference element, preventing an actuation stroke of the manually operable trigger.
