A portable apparatus for dispensing and foaming of a product, including: a product container which contains a product that is to be foamed by and dispensed from the apparatus; a gas container, at least containing a gas, for example a single gas or a gas mixture, wherein the gas substantially does not contain any greenhouse gases such as N.sub.2O; a dispersion device, having a product entrance that is connectable to the product container for receiving product, the dispersion device further being connectable to the gas container for supplying the gas to the product during product discharge; a processing device downstream of the dispersion device for performing a mixing treatment and/or pressure reduction on the product provided with the gas; and a product dispensing head, being part of a top section of the apparatus and being arranged downstream of the processing device.

A container whose content can be removed easily by a consumer. The container should be inexpensive to produce while being extremely easy to operate by the consumer, should provide a high degree of flexibility with respect to the choice of the propellant gas (pressure and type of gas) and should achieve a long storage life for the contents, even after the container has been tapped. The container comprises a fill chamber (40), a pressure chamber (6) and a pressure valve (10). The fill chamber (40) is formed by a container base (2), a container wall (7) and a container upper face (8), and a first pressure (p.sub.B) prevails in the fill chamber (40). The pressure chamber (6) is formed by the container base (2) and a pressure chamber base (5) and a second pressure (p.sub.D) prevails in the pressure chamber (6). The pressure valve (10) is connected to the container base (2) and the pressure chamber base (5). The pressure valve (10), when open, establishes fluid communication between the fill chamber (40) and the pressure chamber (6), and the pressure valve (10), when closed, separates the fill chamber (40) and the pressure chamber (6) in a fluid-tight manner from one another.

A fluid dispenser head (T) including a spray wall (26) that is perforated with a network of holes (O) through which the fluid under pressure passes so as to be sprayed in small droplets; the dispenser head being characterized in that the network of holes (O) comprises at least two series of holes (O), with the holes (O) of a given series presenting holes that are substantially identical in size, and with the holes (O) of different series presenting holes that are different in size, such that one series of holes (O) generates a spray of small droplets with droplet sizes that define a first Gaussian distribution, while another series of holes (O) generates a spray of small droplets with droplet sizes that define a second Gaussian distribution that is offset relative to the first Gaussian distribution, thus producing a complex spray having at least two distinct Gaussian distributions.

A flow guide device of a spray container which comprises a bottle, a nozzle having a flow guide pipe and a straw is configured to be connected between the flow guide pipe and a suction pipe. The flow guide device includes a connecting pipe, a check valve and a check ball. The connecting pipe is connected with the flow guide pipe, which has a plurality of back flow passages and forward flow passages formed on the inner edge thereof. The check valve is arranged between the connecting pipe and the flow guiding pipe. The check ball is arranged in the connecting pipe and located on the port of the straw. When the spray container is in an inverted state, the liquid enters the connecting pipe, the one-way valve and the flow guide pipe from the backflow channel, and the check valve, wherein the flow guide pipe through the back flow passages is finally sprayed out. Accordingly, the flow guiding device has a simple structure and is convenient to assemble and capable of reducing the overall manufacturing costs.

A lubric gel composition for personal defense includes a fatty acid at a concentration ranging from 5 wt % to 10 wt % of the composition, a thickening agent at a concentration ranging from 1.75 wt % to 8.75 wt % of the composition, a detergent at a concentration ranging from 1.03 wt % to 4.07 wt % of the composition, a surfactant at a concentration ranging from 2 wt % to 15 wt % of the composition, and water at a concentration ranging from 66 wt % to 90.21 wt % of the composition.

According to the invention there is disclosed a dispenser device for dispensing a medicament, the device comprising at least one component having a coating that comes into contact with the medicament during storage or use of the device on at least one surface thereof, the coating comprising a cross-linked non-diamond like carbon layer comprising 50 At % hydrogen or less and having an interface with the underlying surface of the component.

The present disclosure relates to, inter alia, a formulation in a package. The formulation comprises one or more active agents and is co-mingled with a whipping agent prior to being filled under pressure into the package. The whipping agent is added in sufficient amounts to be dispersed in the formulation. The pressurized package is under sufficient pressure suitable to maintain the whipping agent dispersed in the formulation; and the pressurized package is under sufficient pressure to expel the formulation as a whipped formulation upon application of external force on the formulation in the package.

A miniature pump including a first chamber, a second chamber, a deformable membrane provided within the second chamber that divides the second chamber into first and second sub-chambers, the second sub-chamber defining a reservoir configured to contain liquid to be dispensed, a passage that connects the first chamber to the first sub-chamber, and an outlet in fluid communication with the reservoir, wherein pressurized fluid within the first internal chamber flows through the passage and into the first sub-chamber to compress the deformable membrane and cause liquid contained within the reservoir to flow out from the reservoir through the outlet and wherein the deformable membrane does not generate significant restoring forces when it is deformed and, therefore, will not return to its initial undeformed shape unless the reservoir is refilled.
