摘要:
A universal wall plate which can be secured to a wall and to which a variety of dispensers can readily be secured and removed with minimal effort, without the need to remove the wall panel and without causing damage to the wall.
摘要:
A replaceable fluid container carrying a spray pump with a nozzle which directs spray directionally in which an arrangement is provided for orientating the nozzle into a desired orientation on insertion of the container into a dispenser.
摘要:
A fluid dispenser comprising a dispensing mechanism, a housing and a container having an interior. The container is removably coupled to the housing for dispensing fluid from the container by the dispensing mechanism. The housing has a guard recess opening downwardly and an access opening into the recess. A piercing member is secured in the recess. The container has a protuberance which is adapted to be received in the recess such that when the container is being coupled to the housing, the protuberance on the container is inserted upwardly into the recess and moved into the piercing member to pierce the protuberance with the piercing member. On the piercing member piercing the container, an air passageway is provided providing communication between the interior of the container and the atmospheric air. Preferably the piercing member is secured in the guarded recess against engagement other than with elements inserted into the recess via the access opening.
摘要:
An object of the invention is to provide a dispenser which permits its cover to be either locked when closed or unlocked a dispensing device including a lock mechanism for locking a cover to a housing and providing therewith a blocking member which is either coupled to the housing in an inoperative position or can be coupled to the housing in a position which prevents locking of the lock mechanism. The blocking member may preferably be integrally formed from plastic as the same material as another component of the dispenser, preferably from injection molded integrally with a back plate for the housing, at a location which is not visible when the dispenser is used and with the blocking member being removably connected to the housing back plate by a frangible connection which may readily be broken to separate the blocking member from the housing back plate such that the blocking member may be suitably positioned and coupled to the dispenser in a position which prevents locking of the lock mechanism.
摘要:
A dispenser with an activation lever which extends laterally to one side of the dispenser and is particularly adapted for engagement by an elbow of one arm of a user and particularly adapted for dispensing fluid as onto the hand of a second arm of the user thereby avoiding the need for the activation lever to be engaged by a hand of a user.
摘要:
Liquid soap dispensers including a vacuum relief valve which comprises an enclosed chamber having an air inlet open to the atmosphere and a liquid inlet in communication with liquid in the reservoir and in which the liquid inlet opens to the chamber at a height below a height at which the air inlet opens to the chamber. The vacuum relief valve permits relief of vacuum from the reservoir without moving parts or valves.
摘要:
There is disclosed a method and apparatus for clearing waste water pipes and/or grease traps clogged with grease, with the method comprising the steps of: providing a dry agent comprising bacteria and enzymes; mixing dry agent comprising bacteria and enzymes with an amount of water sufficient to cause in-situ production of an aqueous mixture; maintaining the aqueous mixture in an activator vessel structure to activate the aqueous mixture for a time sufficient to form an aqueous solvent for cleaning or clearing fatty residues and/or grease; contacting the waste water pipes and/or grease traps containing fatty residues and/or grease with the aqueous solvent to dissolve the grease and/or fatty residues; and thus cleaning the waste water pipes and/or grease traps by biodigesting fatty residues and/or grease deposited in the waste water pipes and/or grease traps.
摘要:
A nozzle for dispensing viscous fluid to avoid spraying and stringing, the nozzle including an inner tubular portion of a first cross-sectional area and an outer tubular portion of a second cross-sectional area, the inner tubular portion opening into the outer tubular portion and the outer tubular portion having an outlet, wherein fluid passes through the inner tubular portion into the outer tubular portion and subsequently out of the outer tubular portion via the outlet.
