The present invention discloses an aerosol container (100) comprising a body (101) divided into a first chamber (10) and a second chamber (20) by a divider (102), in which the first chamber (10) is under atmospheric pressure and configured to receive a customisable content through an inlet (200) at the body (101) either or both during and after production of the aerosol container (100), and the second chamber (20) is under a pressurised environment and prefilled with a pressurised content; wherein the body (101) includes a mechanism (104) which, when activated, acts on the divider (102) so as to allow mixing of the customisable content and pressurised content to form a mixture to be dispensed from the body (101) through an outlet (300).

The invention comprises an apparatus and method of manufacture thereof for forming a frothing agent, including the steps of: forming a frozen pellet by at least partially immersing a first material in a liquid, the first material including at least one of: (1) a solid particle comprising at least thirty percent nitrous oxide by mass and (2) a liquid drop comprising at least thirty percent nitrous oxide by mass; sealing the frozen pellet in a container comprising an initial pressure exceeding one hundred pounds per square inch; and heating contents of the container, the step of heating resultant in: (1) a phase change of the nitrous oxide; and (2) formation of the frothing agent.

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.

A two-component pressurized can having a body, a dome, a valve arranged in the dome, an inwardly curved bottom, an upper chamber and a lower chamber for a first and a second component, which chamber are separated from one another by a separating element, and an opening device which is arranged in the bottom, can be activated from outside and, upon actuation, removes the separation between the chambers for the first and second component, wherein the separating element between the chambers is a piston which is mounted so as to be displaceable in the pressurized can and which has at least one opening closed by a closure element, and the opening device has an opening element which extends through a passage in the bottom and is suitable for separating the closure element from the at least one opening of the piston.

A pressure vessel apparatus for dispensing skin care products comprises a multi-chamber bottle capable of containing a pressure of above 35 psi. Separate chambers for liquid contents, mixing of the liquid with active ingredients, and effectively dispensing the resulting product are provided.

The invention provides an aerosol container comprising a body (100) including an outer chamber (110a) and an inner chamber (120a) positioned within the outer chamber (110a), the inner chamber (120a) having a divider (121) that separates it from the outer chamber (110a), and an opening, a puncture member (300) for rupturing the divider (121); and an aerosol valve assembly (200) enclosing the opening of the inner chamber (120a) and including any one or a combination of a content-filling mechanism, gas-discharging mechanism, rupturing mechanism and content-dispensing mechanism. Upon activation of the aerosol valve assembly (200), the content-filling mechanism enables the formation of a content-filling passage to allow external content to be added into the body (100), the gas-discharging mechanism enables the formation of a gas-discharging passage to allow unwanted or excess gas to be released out of the container, the rupturing mechanism acts on the puncture member (11) to rupture the divider (121) so as to allow coalescing of content within the inner chamber (120a) and outer chamber (110a) to form a coalesced content, and the content-dispensing mechanism enables the formation of a content-dispensing passage to dispense the content out of the body (100).
