A device having a body (10), a reservoir (100) axially slidable relative to the body (10), a metering valve (200), a blocking element (500), a triggering element (600), a triggering system controlled by inhalation (60), an actuating member (800) cooperating with the blocking element (500), a cover (11) with a central axial sleeve (110) with a lower axial edge (111), a push member (810) mounted in the cover around the central axial sleeve (110), and a spring (850) disposed around the central axial sleeve (110) between a bottom of the cover and the push member. The lower axial edge (111) of the central axial sleeve is deformed after assembly of the push member and the spring in order to produce a retention collar of the push member and form a pre-assembled subassembly that is fixed to the body.

Provided is a multilayer-structured discharge container having a simple structure, capable of facilitating the loading of a substance to be contained and a pressurizing agent, and capable of facilitating the ejection of the pressurizing agent after use. A discharge container in which a valve mechanism is provided with a stem having two independent in-stem paths, one in-stem path communicates with an in-holder discharge path, the other in-stem path communicates with an in-holder gas path, a contained substance is discharged by closing the other in-stem path, and the pressurizing agent is ejected by opening the other in-stem path. The discharge container is capable of causing a pressurization chamber and the atmosphere to communicate by removing a push-button from a valve assembly and pressing down a stem of a valve mechanism (switching operation).

A fluid dispenser apparatus includes a sealed fluid reservoir container storing a volume of a fluid under a pressure higher than at least 140 psi, a nozzle juxtaposed with the sealed fluid reservoir container, and a trigger mechanically coupled with the nozzle. The nozzle has a fluid inlet that is configured to fluidly couple with the volume of the sealed fluid reservoir container and a fluid outlet configured to emit a stream of the fluid. When activated the fluid inlet of the nozzle is caused to permanently unseal the sealed fluid reservoir container and relate substantially all the fluid under pressure in the volume through the fluid outlet as the stream in a direction determined by a user.

Some embodiments of the present disclosure include a sanitizing device for sanitizing a medical device. The sanitizing device may include a spray canister configured to accommodate a volume of a sanitizing fluid, the spray canister having at least one spray head extending therefrom, wherein the spray head is configured to expel sanitizing fluid when depressed; a body with an openable lid, the body configured to accommodate the spray canister, wherein a distance between an upper surface of the spray canister and an interior surface of the lid is sufficient to accommodate the medical device; and a lid protrusion extending downwardly from an interior surface of the lid, wherein the lid protrusion aligns with the spray head when the spray canister is positioned within the body. When the lid is closed, the lid protrusion may depress the spray head, resulting in the sanitizing fluid being expelled from the spray head.

A discharge apparatus for discharging contents in an aerosol container, comprising, a first flow channel connected to an aerosol container; a second flow channel connected to the first flow channel; a support configured to support at least a part of the second flow channel; and a change unit configured to change a shape of the second flow channel, wherein the support changes a support position of the second flow channel in response to a change in a shape of the second flow channel, is provided. In addition, an unmanned aerial vehicle on which the discharge apparatus is mounted is provided.

An inhaler including a housing having a chamber to receive a valved canister and a stem block, and a mouthpiece in fluid communication with a passage of the stem block; and an actuation mechanism including configured to engage an outer surface of the stem block at a predefined angle relative to the longitudinal axis of the stem block to cause the downward movement of the stem block to activate the valve and release the aerosolizable liquid as the dose of the aerosolized spray out of the mouthpiece of the mechanical inhaler.
