The present disclosure discloses and describes a vapocoolant dispenser. Specifically, the dispenser comprises a housing and container of vapocoolant, the dispenser configured to receive a sterilizable dose of high energy radiation and to provide a sterile, hermetically sealed vapocoolant dispenser.

A container comprises a body of plastics material with a “bag-on-valve” arrangement. The bag depends from a valve and contains a post-foaming gel cleansing composition. A propellant is provided in the container outside the bag, so as to exert a pressure on the post-foaming gel cleansing composition in the bag, such that when the valve stem is depressed to open the valve the post-foaming gel cleansing composition is expelled through the valve stem. The container comprises a cap and the cap is provided with a conduit therethrough to guide the composition from the valve stem to an exit orifice. The conduit comprises an expansion chamber for receiving the composition from the valve stem, a neck having a smaller diameter than the expansion chamber for receiving the composition from the expansion chamber, and a nozzle provided with an exit orifice and having a diameter larger than the neck.

To provide a propellant which has sufficient propelling performance and of which a component to be sprayed imposes low environmental burden, a propellant composition and a sprayer. A propellant composition comprising a propellant containing 1-chloro-2,3,3,3-tetrafluoropropene and a pressurizing agent, and a sprayer comprising the propellant composition, a container in which the propellant composition is contained, and a spray unit to spray the propellant composition to the outside of the container.

A valve assembly for a dispenser. The valve assembly includes a valve body that extends about a longitudinal axis and defines an outer surface and an inner passageway. The valve body includes a first valve body surface and a second valve body surface opposite the first valve body surface. A valve stem extends through the inner passageway and includes an outer stem surface, an inner stem surface opposite the outer stem surface, and a first orifice extending from the outer stem surface to the inner stem surface. A resilient member is disposed on at least a portion of the first valve body surface. The resilient member is made from a resilient polymeric material and has a non-linear compression profile.

A valve stem extends through the inner passageway and includes an outer stem surface, an inner stem surface opposite the outer stem surface, and a first orifice extending from the outer stem surface to the inner stem surface. The valve assembly includes a retaining member joined to the valve stem, wherein the retaining member extends outward from the outer stem surface. The valve assembly includes a resilient member and one or more force concentrators configured to operatively engage the resilient member.

An aerosol product comprising an aerosol container comprising a container body and an aerosol valve fixed to an opening of the container body, and an aqueous concentrate and a propellant being filled in the aerosol container, wherein the aqueous concentrate comprises an active ingredient having reactivity with oxygen, and an inert ingredient is present in at least a part of an injection passage of the aerosol valve, even though the aqueous concentrate comprising an active ingredient having reactivity with oxygen is filled, oxidation of the active ingredient is inhibited in the aerosol valve, and an aerosol product that can be stored stably for a long period of time and a method for manufacturing the same can be provided.

A peelable nail coating spray comprises at least one film-forming polymer, at least one copolymer, at least one thinner, at least one keratinous nourishing ingredient, and a pressurized container to store the peelable nail coating spray. A method of applying a peelable nail coating spray providing a peelable nail coating spray comprising a at least one film-forming polymer, at least one copolymer, at least one thinner, at least one keratinous nourishing ingredient, and a pressurized container to store the peelable nail coating spray, releasing the peelable nail coating spray from the pressurized container, applying the peelable nail coating spray on a nail surface to form a layer, and peeling off and/or washing off the layer and optionally the second layer from skin or cuticles surrounding the nail surface after the layer is dry.

Fit testing is conduct to ensure that gas mask provide proper protection to workers that may be exposed to airborne contamination. Standard fit test procedures require the mixing of fit test compounds to specific fit testing composition required for threshold testing and subsequent fit testing. A device is needed for easy mixing of the components of the fit test composition and easy delivery of fit test composition during a fit test. For example, a device for fit testing of a gas mask on an individual wearer may include a sprayer, at least one ampoule containing a fit testing component, and a reservoir containing the ampoule and a solvent for the fit test component. The reservoir may be hollow body having a sealed inner volume. The reservoir may be deformable to break at least one hermetically sealed ampoule without tearing or otherwise breaking the reservoir. Therefore, the ampoule may be broken within the reservoir to mix the gas mask fit testing component into the solvent to generate the desired concentration for either a threshold test or gas mask fit test.
