Bottle insert ensures safe, accurate liquid dispensing.

As long as there have been toilets, janitors have been on their hands and knees swabbing and wiping them clean (or almost clean). No wonder the worker morale has been so low and the turnover rate so high.

To address this issue, Bob Robinson Sr., founder and president of KaiVac, Inc., set out to develop a more dignified, yet more productive method of cleaning restrooms. By combining pressure washing, chemical injection, wet vaccuming and other tools on a single platform, Robinson revolutionized restroom cleaning. This combination resulted in the first No Touch Cleaning system, called the KaiVac. This system is easier and faster, and completely removes soil better than any other method, Robinson claims.

However, the possibility of toxic spills and workplace contamination when chemical concentrates are mixed and dispensed manually by untrained personnel has always been a concern. To eliminate this problem, KaiVac is using an automatic, self-venting, closed-loop filling and dispensing system called SafTflo, developed by RD Industries, a designer and manufacturer of closed-loop dispensing systems. One of the primary components within the system is a patented, breathable membrane that allows gases to escape, relieving positive or negative pressure in the container for accurate and continuous liquid dispensing. This automatic, self-venting feature assures accurate product metering and prevents costly mixing mistakes. The closed-loop SafTflo system provides spill containment and prevents the loss of costly product. Filling and dispensing operations are cleaner and safer.

The SafTflo bottle insert which is available for both upright and inverted bottles, includes a standard pigmented polypropylene plug insert, a standard valve stem, a self-venting valve with eight perforations, a stainless-steel spring and a liner retainer with a 1/4-in. dip tube that is up to 16 in. long. The top surface is recessed into the bottle throat for shipping and storage. When the cap adapter is attached to a bottle, a check valve opens to allow liquid flow. An optional, precalibrated, automatic dilution-control module installed in the bottle insert tube measures a prescribed amount of concentrate, thus eliminating costly dilution mixing mistakes by untrained personnel.

"The SafTflo system has worked very well for us," says KaiVac VP of Marketing Tom Morrison. "It insulates workers from the chemicals and prevents accidental spills by the way it seals the bottle. The check valve prevents chemicals from flowing back into the bottle and ensures against accidental mixing when a worker changes the cleaners he's using."
