A method of forming a coating on a cylindrical paperboard container having a closed end. The method includes the steps of heating a gas from a first temperature to a second temperature; providing the gas to a first inlet of a nozzle; providing a polymer in a liquid state at a third temperature; providing the polymer to a second inlet of the nozzle; and spraying the polymer onto the cylindrical paperboard container using the nozzle; wherein the second temperature is greater than the third temperature; and the second temperature and third temperature are such that the gas maintains the polymer in the liquid state at least until the polymer comes into contact with the cylindrical paperboard container. A system for applying a coating to a plurality of cylindrical paperboard containers and a container for a consumer product are also provided.

In order to provide an aerosol device (100) that makes it possible to provide an aerosol having an optimised composition, in particular optimised droplet size distribution, it is proposed that the aerosol device (100) should include the following: an aerosol casing (102); one or more aerosol nozzles (104) for generating an aerosol stream from a carrier gas and a liquid, wherein the one or more aerosol nozzles (104) are directed into an interior (106) of the aerosol casing (102) and/or are arranged in the aerosol casing (102); one or more carrier duct connection points (156) for connecting one or more carrier ducts (158), by means of which the aerosol is guidable away from the interior (106) of the aerosol casing (102).

A foam dispenser having a metal housing has a spool valve socket therein. A metal handle extends from the housing. A spool valve is disposable within the spool valve socket. A trigger couplable to the spool valve enables the spool valve to be rotated between open and closed orientations within the housing. The spool valve has internal channels for selectively passing liquids through the spool valve in the open orientation and not in the closed orientation. The spool valve also has a channel for selectively passing a gas through the spool valve in both the open and closed orientations.

In a cleaning method for removing adhesive residues from surfaces, in particular after separating an adhesive connection between adhesively joined partners, liquid carbon dioxide from a reservoir enters a jet, apparatus and is guided there through a first dosing unit into an expansion chamber wherein a cold-resistant liquid is then supplied to a mixture created in the expansion chamber from gaseous carbon dioxide and carbon dioxide particles and wherein the mixture, to which the cold-resistant liquid has been added, exits the jet apparatus via an outlet opening thereof. Furthermore, a jet apparatus removes adhesive residues from surfaces.

A fan-shaped air suction spray nozzle automatically adjusting an air suction speed is provided in the present invention, which includes a spray nozzle body and a liquid channel, the spray nozzle body being provided with a liquid channel in communication with a nozzle hole, and further includes a pressure groove and an air intake channel, wherein an inlet section of the liquid channel is in communication with the pressure groove, and the air intake channel is in communication with the liquid channel after penetrating through the pressure groove; an air intake orifice plate is installed in the pressure groove through an elastic damping apparatus, and a change of the pressure at an inlet of the liquid channel causes the air intake orifice plate to move between the pressure groove and the air intake channel; the air intake orifice plate is provided with several through holes of the same or different sizes, which are configured to change the air intake volume in the liquid channel as the air intake orifice plate moves in the pressure groove.

The present utility model relates to a fogger, comprising: a casing with an air suction inlet and a spray port; an air duct assembly located in the said casing, wherein the air duct assembly includes an air duct shell and a fan, of which the said air duct shell has an air inlet, an air outlet, and an air duct that connects the said air inlet and the said air outlet, and the said fan is located in the said air duct; the said air inlet is connected to the said air suction inlet, the said air outlet is connected to the said spray port; and a liquid storage tank located in the said casing, wherein the liquid storage tank delivers liquid to the said spray port via a liquid delivery tube, and the said air duct is connected to the said liquid storage tank via an air delivery tube. A fogger of the present utility model can effectively improve the convenience of use.

Pump dispenser comprising a pump and a container for liquid to be dispensed, the pump comprising a pump body mounted in the neck of the container and a plunger reciprocable relative to the pump body to alter the volume of a pump chamber defined in the pump body and having an inlet and an outlet, the outlet leading through an outlet passage to a discharge opening. The pump cylinder body is retained at the container neck. A vent is provided in the cylinder body wall adjacent the neck edge. A vent block ring is disposed in the cylinder body adjacent the vent, and is moveable between blocked and unblocked positions relative to the vent. The vent block ring has an integral upward projecting formation which is engaged by part of the plunger in a locked-down position of the plunger, so that when the plunger is locked down the vent block element blocks the vent, while in a relatively extended position of the plunger the vent block element is in the unblocked position.
