A trigger dispenser device (1) envisages a secondary liquid aspiration duct (50) in communication with the dispenser duct, and a primary liquid aspiration duct (8) in communication with the container, off-axis with each other. Between these, a joining compartment (64) is provided communicating upstream with the primary liquid aspiration duct (8) and communicating downstream with the secondary liquid aspiration duct (50) to form the fluidic connection between them. In particular, the container (C) is of the type with built-in suction pipe.

In a pump dispenser having a form where a user grasps a grip to push down a finger putting portion with the user's thumb, the present invention provides a push-type pump dispenser that has a good transmission property of a finger force and is excellent in operability.

The present invention is a push-type pump dispenser A that injects liquid within a cylinder portion 11 from a nozzle portion 32 by pushing down the finger putting portion 31 located above a grip portion 12 in a state where the grip portion 12 has been grasped by a user, wherein a finger abutting portion S of the grip portion 12 is located behind a power point P1 of the finger putting portion 31.

A vessel cap of cosmetics includes a coupling member formed on an inner circumferential surface thereof with a female screw part such that the female screw part is engaged with a male screw part formed on an outer circumferential surface of an opening formed in an upper portion of a vessel which receives liquid-phase contents, a spuit tube which is coupled to the coupling member to suck and discharge the contents received in the vessel, and a pumping unit of the spuit tube, which sucks the contents into the spuit tube after inserting the spuit tube into the vessel in a state that internal air of the spuit tube is partially discharged. The spuit tube is inserted into high-viscosity and liquid-phase contents received in the vessel after the internal air is discharged from the spuit tube, thereby previously preventing the discharged air from being introduced into the spuit tube.

A spray head for a spray bottle includes a spray mechanism connected to a tube that extends into the spray bottle. The spray mechanism draws fluid from a bottom of the spray bottle, through the tube, to produce a spray of the fluid. A threaded female fitting attaches to a threaded top of the spray bottle. The threaded female, when screwed on to the threaded top of the spray bottle, securely attaches the spray head to the spray bottle. A refill valve, when opened, provides a conduit to refill the spray bottle so that fluid can be poured into the spray bottle without unscrewing the threaded fitting and removing the spray head from the spray bottle. A refill valve cap, when in a shut position, closes the refill valve to prevent spilling of the liquid when the spray bottle is not being refilled.

Suction device for a liquid product present in a dispenser has a container 6 provided with means for sampling the product 7. The device is developed about a central axis X and has a centralised product suction channel 8 coaxial to the central axis X and having an inlet 14 and an outlet; and annular suction means connected to the inlet 14 of the centralised suction channel 8.

Air purge device for an airless liquid product dispenser having a container equipped with means for sampling the product. The device has a bleed ring that has a deformable lip seal accommodated inside a protective part designed to be inserted into the container. The deformation of the lip when mounting the air purge device in the container causes the air to be purged from the container.

The present invention relates to a device for cleaning and/or disinfecting surfaces, particularly for cleaning inner surfaces of the toilet bowl. The device comprises an elongated housing connected to a bottle with the cleaning and/or a disinfecting liquid, and a pumping mechanism for pressurizing said liquid composition, and at least one nozzle for the output of said liquid composition, wherein the nozzle is in fluid communication through a conduit of the device with said pumping mechanism. The pumping mechanism is provided at one side of said housing and said at least one nozzle is provided at the opposite side of the housing.

A connection system between a head and a bottle of a trigger dispensing device includes a main skirt having a first flexible tab and a neck (2b) having a first sloping plane and a first pocket. The first flexible tab extends circumferentially from a first end to a second end, and the first end is joined to an annular wall by a closing wall. The system also provides for an auxiliary window obtained through the annular wall of the main skirt, and a rigid auxiliary tooth of the neck, suitable to snap into the auxiliary window.

A trigger type sprayer capable of easily performing air vent in a space between a second valve and a first valve, and preventing leakage of liquid in use is provided. The present invention includes a body 11 having a first flow channel 11a through which liquid can flow, a second flow channel 11d communicating with the first flow channel 11a, and a cylindrical cylinder chamber 11b communicating with the second flow channel 11d; a hollow piston 13 slidably incorporated into the cylinder chamber 11b, having a valve seat 13b and a hollow portion 13d of a second valve 14, and sliding back and forth according to operation of a trigger 12; the second valve 14 incorporated into the hollow portion 13d of the hollow piston 13 and positioned at a downstream side; and a first valve 15 incorporated into the cylinder chamber 11b and positioned at an upstream side, wherein the first valve 15 is pressed by the second valve 14 so that the first valve 15 is opened.

The application provides formulations for the topical administration of an active agent comprising at least one steroid, in the form of topical sprays that are propellant-free, and/or substantially non-foaming, and/or alcohol-free. The present application also provides processes for preparing such compositions and methods of using them in management of skin diseases or disorders such as psoriasis, dermatoses, and other associated skin diseases or disorders.
