A shoulder cover for an aerosol container that can be readily positioned and attached to the aerosol container having two stems. The shoulder cover is attached to a mounting cup that includes an upper tier part having two stems protruding from a top wall thereof and having long sides and short sides, and a cylindrical part. The shoulder cover includes an outer circumferential wall, a roof wall, a cylindrical wall extending downward from the roof wall, and locking structure provided to the cylindrical wall and retaining the shoulder cover by engaging with the cylindrical part of the mounting cup, and positioning structure for fitting with the upper tier part to thereby position a mating position of the shoulder cover is formed.

A liquid-dispensing device including a cap for protecting a liquid-dispensing opening, the protective cap being provided with a pad for absorbing residual liquid, made of an absorbent material, the absorbent pad being fastened to a support made of a more resistant material than the absorbent pad, the support being furthermore fastened in the protective cap.

A dispensing device that attaches to a container has: (a) a hollow tube with opposing entrance and exit ends with a connector on the entrance end and a wall defining a flow channel; (b) a sleeve with opposing entrance and exit ends slidably extending over the hollow tube; (c) a sealing gasket between and contacting the hollow tube and sleeve; (d) a trigger mount rigidly attached to the hollow tube or container; (e) a trigger hingedly connected to the trigger mount and operatively connected to the sleeve; (f) an elastic element between the trigger and the hollow tube and/or container; wherein the exit end is closed and there is an opening through the hollow tube wall proximate to the exit end; the sleeve has an open dispensing end, reduces in inside diameter at dispensing end and engages the hollow tube when closed and disengages from the hollow tube when open.

Described herein is an aerosol hairspray product including a container including a container wall which encloses a reservoir. The reservoir includes from about 40% to about 70% of a hairstyling formulation and from about 30% to about 60% of a dimethyl ether propellant. The hairstyling formulation includes water, one or more hairstyling polymers, and from about 0.05% to about 2% alcohol. A spraying device is attached to the container. The spraying devices includes a valve including a valve housing including a vapor tap including a vapor tap area. A dip tube is connected to the valve. The dip tube includes a dip tube orifice including a dip tube orifice area. The ratio of the vapor tap area to the dip tube orifice area is from about 0.005 to about 0.15.

A receptacle for storing a substance, wherein the receptacle has a cartridge and a valve. A valve inner side is here covered by a sealing element, with the result that a receptacle volume is substantially delimited by the cartridge and the sealing element.

A multi-chambered bottle includes first and second chambers, a metering stage, a pour spout and a cap. The metering stage includes first and second metering stage sections connectable to respective mouths of the first and second chambers. Each metering stage section comprises a nozzle having a liquid inlet orifice and a liquid outlet orifice, and a vent tube having an air inlet orifice and an air outlet orifice at opposite ends of the vent tube, the air inlet orifice to be disposed outside of the respective chamber and the air outlet orifice to be disposed inside of the respective chamber, the vent tube disposed relative to the nozzle such that a line crossing a center of the air inlet orifice and a center of the liquid outlet orifice forms an acute angle with a normal axis of the bottle.
