A nasal spray bottle with improved nozzle, which has a cap assembly, a nozzle assembly having a flap guidance, a bottle coupling assembly, a dispenser mechanism, and a bottle assembly. The nozzle assembly couples to the bottle coupling assembly, the bottle coupling assembly mounts onto the bottle assembly, and the dispenser mechanism is inside along the nozzle assembly, the bottle coupling assembly, and the bottle assembly. The flap guidance has first and second transversal edges, first and second longitudinal edges, and a central edge. The flap guidance is fixedly attached around the nozzle body by the central edge. The flap guidance is oval shaped. The flap guidance is attached around the nozzle body defining a predetermined angle.

A nasal spray guide may include a collar defining a lumen configured to receive a nasal spray tip, a shoulder surface extending radially outward from the collar, wherein the shoulder surface is angled relative to the lumen; and a cap defining a cavity and configured to engage the shoulder such that the cavity and the lumen are substantially aligned. In some variations, a method of using the nasal spray guide includes positioning at least a portion of a nasal spray device in the lumen such that a distal portion of the nasal spray device is exposed, inserting the distal portion of the nasal spray device in a nostril of a user until the shoulder of the nasal spray guide is seated against a nasal surface of the user; and actuating the nasal spray device while the shoulder of the nasal spray guide is seated.

A spray canister dispenser for mounting to a spray canister to allow for more convenient actuation of a nozzle. The spray canister dispenser includes a housing that removably mounts to an upper end of a spray canister. A first channel is disposed on an interior sidewall of the housing and can align with a lip of the spray canister to selectively couple thereto. An actuator assembly having a trigger handle and an actuator extends from a moveable plate secured to the housing and can transition between a dispensing and resting configuration. In the dispensing configuration, the actuator is forced against a spray canister nozzle to dispense substance therefrom. In use, the trigger handle is positioned on a forward side of the spray canister, wherein the housing is on a rearward side of the canister. An aperture is disposed within the trigger handle to allow the substance to be dispensed therethrough.

A saddle seal assembly for a high-pressure airless spray nozzle having a spray tip includes a metal sealing sleeve, a cylindrical elastic seal, and a metal sleeve insert. The metal sealing sleeve may include a first saddle-shaped semi-cylinder surface closely matching with an outer surface of the spray tip to form an outer hard sealing structure. The cylindrical elastic seal may include a second saddle-shaped semi-cylinder surface closely matching with the outer surface of the spray tip to form an inner flexible sealing structure. The metal sleeve includes a hollow cylinder shape that matches the inner surface of the cylindrical elastic seal. A first end portion of the cylindrical elastic seal is configured to be inserted into the metal sealing sleeve, and the first saddle-shaped semi-cylinder surface and the second saddle-shaped semi-cylinder surface are configured to be spliced to form a continuous saddle-shaped semi-cylinder surface, to thereby seal a stepped inlet hole of the high-pressure airless spray nozzle. The metal sleeve insert is attached onto the inner surface of the cylindrical elastic.

A fluid dispenser head having a single-piece head body (1) forming an axial inlet well (12) suitable for connecting to a dispenser member (D), such as a pump or a valve; and a transverse feed duct (13) that extends from the axial inlet well (12). The dispenser head also has a dispenser orifice (21) in fluid communication with the transverse feed duct (13). A filter (F) is situated in the axial inlet well (12) and/or in the transverse feed duct (13).

The present invention relates to a spray device, comprising a spray nozzle body (2) and a substantially planar membrane layer (6) suspended over a nozzle cavity (3) to generate microjets, especially for pharmaceutical applications, in particular preservative free formulations. The nozzle body (2,8) contains a microbial barrier, particularly a microvalve (23,24) between a fluid supply channel (9) and said cavity (3).

A holding device is used to maintaining a push button of a spray container to be pressed to release contents without continuous press by an operator. The holding device for a spray container comprises a supporting part which is placed around the push button, an adjusting part having a pillar-shaped portion standing on the supporting part and a diving board-shaped portion connected to the pillar-shaped portion and extending over a top of the push button, on a top of the diving board-shaped portion having a recess; and an auxiliary part being pillar-shaped and standing on the supporting part, having a protrusion toward the adjusting part to be engaged with the recess.

A liquid pump capable of achieving pressure equilibrium includes a body, piston member, unidirectional input valve, unidirectional output valve, input inner-pipe, unidirectional gas-feeding hermetic-seal valve and input outer-pipe. The body has an input opening, output opening and piston opening. The piston member has a piston space communicating with the piston opening. The unidirectional input valve includes an input plug and input resilient element. The input plug abuts against the input opening. The unidirectional output valve includes an output plug and output resilient element. The output plug abuts against the output opening from outside. An input channel of the input inner-pipe communicates with the input opening. Direction of gas-flow between the unidirectional gas-feeding hermetic-seal valve and the input inner-pipe is opposite input direction of the input channel. The input outer-pipe has an input portion communicating with the input channel. A gas-feeding-channel is defined between a gas-feeding-portion and the input inner-pipe.

A fluid dispenser device having at least one reservoir (20) that is suitable for containing fluid to be dispensed; a pump (1) that is mounted on the reservoir (20); and a dispenser head (2) including a dispenser orifice (3) via which the fluid is dispensed, which dispenser head is suitable for actuating said pump (1). At least a rigid and/or non-deformable portion of the dispenser device is made out of a material comprising an aliphatic polyketone.

The sprayer includes a sprayer housing defining a chamber, and a cylinder within the chamber. The cylinder defines more than one discharge tube positioned in a longitudinal direction within the sprayer housing, the cylinder being selectively rotatable within the chamber. More than one suction tube extends from a lower portion of the sprayer housing. The more than one suction tube is in selective fluid communication with the more than one discharge tube of the cylinder, as the cylinder is rotated within the chamber. The foam sprayer attachment includes a major body defining a discharge channel and a screen traversing the discharge channel. The major body includes a base with a connecting structure that is a raised lip or a cut-out area that conforms the base to a raised ridge on a discharge connection of the sprayer. The connecting structure includes a pair of non-raised lips bracketing each connecting structure.
