A spray cap for use with an aerosol can having a body having a recessed area; and an actuator button removably stored on the recessed area in an opening formed in the recessed area. The recessed area is resilient and flexible to accommodate inserting and removing the actuator. The actuator has a top wall which is curved and ergonomically configured to receive a user's finger. The actuator comprises an opening for dispensing paint or other liquid. The recessed area has flanges on opposite sides of the opening to facilitate insertion and removal of the actuator thereon.

The present invention relates to a nebulizer, such as a spray can, for the topical application of a liquid and/or solid to a surface. The nebulizer is characterized by a valve comprising a mixing chamber designed for forming a colloidal mixture comprising a dispersed phase consisting of a liquid and/or a solid substance and a continuous phase consisting of a propellant gas before delivering the colloidal mixture to the nozzle. The invention also relates to a method for the topical cooling of the skin of a person or animal. In addition, the invention relates to various other uses of the device.

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).

Dispenser [20] and system [100] providing a surface treatment to metal parts, equipment and vehicles for corrosion prevention. The dispenser [20] has an external housing [22] with an actuator [40], a valve for engaging a valve stem [V] of a canister, a button trigger [28] for activation, and a trigger return spring, to bias the button trigger [28] out of engagement with the valve. An outlet [26] from the external housing [22] enables removable attachment of a reusable flexible elongate delivery conduit [60] having a support wire [62]. Delivery conduit is stored wrapped around the external housing, and extends for between at least 2 and 3 feet for use. A fluid delivery end [68] of the delivery conduit includes a delivery nozzle [80] enabling a user to provide a spray pattern for fluid delivery, where the spray pattern dispenses fluid at a 45 angle with respect to the delivery conduit.
