A device for dispensing a fluid substance includes a pressurised container associated with a dispensing valve featuring a supply conduit and a stem endowed with a cavity through which the fluid substance is dispensed, a chamber housed inside the container, and arranged so as to surround at least part of the body of the valve, the chamber delimited by a deformable wall and at least part of the body, the valve being of the three-way type, configured so that when the stem is in a first position, the cavity is isolated from the supply conduit and from the chamber, while the supply conduit is in communication with the chamber, wherein when the stem is in a second position, the cavity is in communication with the chamber, and wherein when the stem is in a third position, the cavity of the stem is in communication with at least the supply conduit.

A propellantless aerosol fluid dispensing system including a reusable pressurizable canister and a disposable fluid containing pouch, the pouch including a valve assembly for dispensing the fluid.

An apparatus (100) for metered dispensing of a liquid from a container (3) and a spray applicator having the apparatus (100). The apparatus (100) comprises a base body (5) and a nozzle body (16) having an outlet nozzle. The nozzle body (16) is mounted so as to be displaceable relative to the base body (5) from a dispensing to a clamping position. The apparatus (100) comprises a reset spring (14) for moving the nozzle body (16) from the clamping to the dispensing position. The nozzle body (16) and the valve body form a burst chamber (19). By pressure on the trigger mechanism (26), the locking of the valve body (10) is triggered and the spray burst spring (7) presses the valve body (10) in the nozzle direction. A non-return valve is arranged upstream in the valve body. The spray burst chamber is connected to the outlet nozzle.

A trigger type liquid ejector includes an ejector body and nozzle, the ejector body includes a vertical supply pipe, ejection barrel, trigger, piston, and cylinder, a recovery passage brings the cylinder in communication with the vertical supply pipe via a space between a piston body and a piston guide of the cylinder formed in the ejector body, the vertical supply pipe has a lower inner tube part where the recovery passage opens, the trigger type liquid ejector further includes an upright and inverted posture adaptor attached into the lower inner tube part where communication between the recovery passage and an inside of a container body is blocked, and a communication passage brings the recovery passage in communication with the inside of the container body forms between an outer circumferential surface of the upright and inverted posture adaptor and an inner circumferential surface of the lower inner tube part.

A dispenser for applying liquid, having a housing with an applicator opening and a liquid reservoir. The dispenser has a ventilation duct by which an ambient atmosphere is connected to the liquid reservoir so that, after the application of liquid, an inflow of air from the atmosphere is permitted into the liquid reservoir. The dispenser is provided with a detection installation which for detecting an application procedure detects air flowing in through the ventilation duct. The dispenser has a protective cap covering the applicator opening on the housing. The dispenser in the ventilation duct has a switch valve operable by activating a push-button on the external side of the housing. The protective cap acts on the push-button when placed on the housing or when the protective cap is being placed thereon to open the switch valve.

A liquid dispenser having a liquid reservoir and a discharge head secured thereto, an outlet valve with a pressure chamber and an opposite valve chamber. The liquid reservoir and the valve chamber are each connected at least in phases to a surrounding atmosphere by a ventilation channel. The two channels provided for this purpose, the reservoir ventilation channel and the valve ventilation channel, are separate channels with separate inlets on an outer face of the discharge head.

A wearable dispenser with a replaceable one-time-use reservoir device is taught, comprising a wrist-band allowing the wearable dispenser to be worn by a user; a base connected to the wrist-band; and a replaceable one-time-use reservoir. The replaceable one-time-use reservoir is comprised of a flexible bladder holding a substance to be dispensed, a housing with a rigid perimeter wall, a flexible top surface attached to the rigid perimeter wall and covering the flexible bladder, a one-way valve, an opening, and a substance to be dispensed. Typically, the substance to be dispensed is hand sanitizer. A user may use their fingertip to press the flexible top surface. Doing so creates additional pressure within the flexible bladder, causing the substance to be dispensed.

An opening/closing nozzle of a discharge pump for a cosmetic container is configured such that it is advantageous in that inflow of air into a nozzle of the cosmetic container can be prevented such that not only degeneration of the content and hardening of the content inside the nozzle, which would otherwise occur if air flows into the nozzle, can be prevented, but the reliability of the product can also be improved.

A dispenser for dispensing liquid or pasty materials has a head part with a dispenser opening. The dispenser opening is formed by lip sections which lie directly on top of each other. A lip section for opening the dispenser opening can be lifted from the other lip section by means of a lifting part that engages on the lip section. The lifting part acts on the lip section with a loading direction that runs transversely to a dispensing direction of the material.

A wearable dispenser with a replaceable one-time-use reservoir device is taught, comprising a wrist-band allowing the wearable dispenser to be worn by a user; a base connected to the wrist-band; and a replaceable one-time-use reservoir. The replaceable one-time-use reservoir is comprised of a flexible bladder holding a substance to be dispensed, a housing with a rigid perimeter wall, a flexible top surface attached to the rigid perimeter wall and covering the flexible bladder, a one-way valve, an opening, and a substance to be dispensed. Typically, the substance to be dispensed is hand sanitizer. A user may use their fingertip to press the flexible top surface. Doing so creates additional pressure within the flexible bladder, causing the substance to be dispensed.
