Abstract
This disclosure relates to an apparatus for dispensing which incorporates a jacketed compressed pellet of soluble material provided with an effective mixing chamber having a restricted opening to a surrounding ambient fluid to serve as a device to control the rate of dissolution of the chemical into the ambient fluid so that the dispensing apparatus has a service life substantially greater than the devices of the prior art.
Claims11
An apparatus for dispensing a soluble chemical into a solvent fluid, comprising:
- pellet means comprising a solid unitary body of said soluble chemical and having substantially planar surfaces for substantially retaining said chemical as a unitary mass prior to dissolving;
- substantially encapsulating non-separable case means in contact with all but a small portion of one of said planar surfaces of said solid unitary body for initially permitting a fluid restricted access to only said planar surface portion of said solid unitary body.
