Abstract
A novel package of available chlorine compound comprised of a stack of a plurality of tablets enclosed in a liquid impervious synthetic material. The package is prepared by placing the stack of tablets in a tube of heat shrinkable synthetic material and then heating to effect shrinkage and to form a tightly adhering tube of synthetic material around the cylindrical exterior of the tablets. The resulting package can be adjusted to size by cutting where desired between tablets. The packages are useful in sanitizing water, particularly swimming pool water by placing them in a strainer basket of a skimmer unit.
Claims16
A novel package of available chlorine compound for placing in the strainer basket of a swimming pool skimmer unit comprised of:
- a. a plurality of tablets of said available chlorine compound:
- 1. each of said tablets having two substantially parallel planes joined to a cylindrical exterior,
- 2.
A method for preparing a novel package of available chlorine compounds for use in a swimming pool skimming unit for sanitizing water which comprises:
- a. placing a plurality of tablets of said compound in a stack:
- 1. each of said tablets having two substantially parallel planes joined to a cylindrical exterior,
- 2. each of said tablets being stacked together with one of said planes of one tablet being adjacent to one of said planes of a next of said tablets and forming a stick of desired length, said stick having a longitudinal axis perpendicular to said planes,
- b. placing said stick on a sheet of heat shrinkable, liquid impervious synthetic material:
- 1. said sheet having at least one heat shrinkable axis perpendicular to two opposite edges of said sheet,
- 2. said longitudinal axis of said stick being positioned perpendicular to said heat shrinkable axis,
- c. heat sealing one of said edges to an opposite of said edges forming a cover for said stick around said cylindrical exterior of each of said tablets, and
- d. heating the resulting covered stick, shrinking said synthetic material around the exterior surface of said tablets and forming a tight, water impervious cover around said stick, whereby said sanitizing occurs when at least a portion of said covered stick is placed into the strainer basket of said swimming pool skimmer, and whereby the available chlorine compound in said covered stick is dissolved at each end of said covered stick by water being circulated through said skimmer.
