Dispenser for rolls of a web-shaped material, such as paper, said dispenser having space for at least two rolls, at which one space is located adjacent the outlet opening ( ) and is intended for a first roll in a use position and the second space is located above the first space and is intended for a roll in standby position. A lock ( ) is intended to keep the second roll in standby position. The disk plate is spring-loaded ( ) and cooperates with the lock such that when a roll is located in place in the disk plate the lock ( ) prevents the standby roll from falling down.

Dispenser for rolls of web-shaped material

A valve assembly can automatically dispense aerosol content from an aerosol container at predetermined intervals without the use of electric power. A diaphragm at least partially defines an accumulation chamber that receives aerosol content from the can during an accumulation phase. Once the internal pressure of the accumulation chamber reaches a predetermined threshold, the diaphragm moves axially, carrying with it a leg so as to unseal an outlet, and thereby initiate a spray burst. A pawl extends from the diaphragm, and engages a retention surface to resist movement of the diaphragm and prolong the accumulation phase. The diaphragm assumes its original position when the pressure within the accumulation chamber falls below a threshold pressure.

Aerosol dispensing valve

A valve assembly can automatically dispense aerosol content from an aerosol container at predetermined intervals without the use of electric power. A diaphragm at least partially defines an accumulation chamber that receives aerosol content from the can during an accumulation phase. Once the internal pressure of the accumulation chamber reaches a predetermined threshold, the diaphragm moves, carrying with it a leg so as to unseal a valve stem, and thereby initiate a spray burst. The diaphragm assumes its original position when the pressure within the accumulation chamber falls below a threshold pressure. A barrier prevents the aerosol container from resupplying the accumulation chamber at a high rate during the spray phase, preferably due to a textured interface between the barrier and a passageway in which it is housed.

Automatic intermittent aerosol dispensing valve

An valve assembly is provided that automatically dispenses aerosol content from a can at predetermined intervals. A diaphragm at least partially defines an accumulation chamber that receives aerosol content from the can during an accumulation phase. Once the internal pressure of the accumulation chamber reaches a predetermined threshold, the diaphragm flexes to initiate a spray phase, during which the aerosol content is delivered from the accumulation chamber to the ambient environment. A rotatable pawl provides resistive pressure and control of diaphragm movement.
