With soap and cleansing foam dispensers, there is a risk that they may be equipped with supply containers of unsuitable liquid or that their intermediate containers may become contaminated. According to the invention, an adapter ( ) that is mounted on an intermediate container ( ) has a coded cylindrical jacket ( ), into which coded parts ( ) that are positioned on the neck of a suitable supply container ( ) can be fitted. To prevent the contamination of the intermediate container ( ), the latter has a spring-loaded internal sealing plug ( ) which ensures the hygienic sealing of the container even prior to use and when the supply container is changed. To prevent interruptions in the operation, a reliable fill-level indicator ( ) is provided. The device thus ensures improved, hygienic dispensing of soap-solution in dispensers ( ).

Device for dispensing soap-solution in a dispenser

The invention relates to a dispenser for foamable liquids which has been improved with regard to the aspects of hygiene and reliability. According to the method, in addition to the pneumatic and hydraulic parts of the dispenser having a configuration which is to a great extent isolated from the external atmosphere, said dispenser has an air chamber ( ) which subjects a nozzle/expansion body ( ) first to an excess pressure and then to a negative pressure during the return stroke (H ) of an air piston ( ) via a lateral bore ( ). As a result, the outlet ( ) is first cleared and any remaining foam in the nozzle/expansion body ( ) is subsequently removed by suction and coagulated into soap solution. During the next working stroke, this minimal quantity of soap-solution is foamed again and expelled.

Towel dispenser

A towel dispenser is provided with a pivoting unit into which a winding roller driven by way of a friction drive is mounted in an easily suspensible manner. An additional loop, which is tightened by a compensator roller in a direction &plus;p, is formed in the dispenser in front of the winding roller, and when clean towel is pulled down a portion of used towel (T&prime;) is used to form the rear part of a loop of cloth (T; T&prime;) used in the front part. Changing used cloth (T&prime;) and loading with clean towel (T) is performed by rotating the pivoting unit, can be carried out in a very simple manner and is completed by opening or closing the cover of the dispenser. A path- and time-dependent control of the towel delivery is integrated in the dispenser.

An evaporation dispenser for freshening the air in closed spaces such as toilets, washrooms and waiting rooms, telephone booths and lifts. A mounting plate is arranged in a housing and is divided into two chambers by a horizontal separating surface. The lower chamber serves as an evaporation space and holds two bottles of active substance which form a saturated atmosphere in the chamber via evaporating elements. This atmosphere is diffused into the outside air by means of a fan which draws the saturated atmosphere from the evaporation space. Simultaneously, ambient air is drawn into the evaporation space to become saturated. Both the discharge of the saturated atmosphere and the drawing in of ambient air may be performed by a single rotor compressor, the rotor being divided into two sections by a radial divider. The discharge of the saturated atmosphere may be controlled by a microcontroller coupled to sensors which monitor activity in the closed space.
