The wall-mounted dispenser for liquid soap has a separable reservoir with an outlet valve. The dispenser further includes a main body with a second outlet valve. When the reservoir is mounted to the main body, a metering chamber is defined between the two outlet valves. The dispensing function is experienced by pushing in a plunger which temporarily decreases the chamber volume and forces the main body outlet valve to open temporarily, thus dispensing a charge of liquid soap. As the plunger is released, a spring return pushes the plunger out, decreasing pressure in the metering chamber, which is equalized as the first outlet valve temporarily opens, admitting a next charge of liquid soap from the reservoir to the metering chamber. The reservoir is replaced by pushing in a resilient release, but the resilient release is preferably normally provided with a stop which must first be moved out of the way. This is to prevent the user from accidentally disconnecting the reservoir when what is really wanted is a dispensation of soap. Should the reservoir be disconnected, pushing in and releasing the plunger will not result in the first outlet valve to open, because pressure will not be lowered in the metering chamber when the plunger is released.

The towel dispenser adapted to store and supply a towel of undeterminate length. At least one of the unused and used portions of the towel is stored in the form of a roll on a shaft. The towel dispenser includes a pair of side walls each having at least one elongated hole. The portion of the side wall defining the inner peripheral edge of the elongated hole is obliquely bent towards each respective other side wall so as to form a tab projecting towards the other side wall. Each end of the shaft is rotatably and slidably received in the respective elongated hole defined by the respective tab, in such a manner that each end of the shaft does not project beyond the plane of the associated side wall.

摘要:
A duster of an improved type for dust capturing efficiency, comprising a cylindrical stem with a continuous spiral thread extending along a portion thereof, a grip engaged with said stem, and fabric materials comprising a band of fiber or fibril bundles which are made of a ductile synthetic resin film or foil which has been split into fibers or fibrils and crimped. The bundles are arranged in a meandering manner. One edge of the band comprises loose edges while the other edge is held together by one or more strings. The secured edge is disposed within the thread with the ends of said material being engaged, respectively, by a supporting member provided at the tip of said stem and an engaging member provided at the root portion of the thread.
