Filed:

Mar 31, 1997

Appl. No.:

8/828597

Inventors:

Nicholas D. Siragusa - Brooklyn NY
Kenneth J. Ward - Dumont NJ
Deborah A. Sarasohn - Elizabeth NJ
Ernest Bernarducci - Rutherford NJ
Arthur Sternheimer - Spring Valley NY

Assignee:

Block Drug Company, Inc. - Jersey City NJ

International Classification:

B65D 8584

US Classification:

2065241

Abstract:

A package for containing two automatic toilet bowl cleaners, one containing a bleaching cleaner and the other containing a detergent cleaner and a fragrance or dye susceptible to degradation by the bleaching agent, has separate pouches to separate the solids. The pouches open in concert to allow simultaneous dispensing of the solids. In operation, the water in the toilet cistern and bowl is cleaned both by the detergent and the bleaching agent, and the fragrance or dye is not affected by the bleaching agent.

Appl. No.:

8/574052

Inventors:

Hin Cheung Hung - Holmdel NJ
Ronnie Albert Carroll - Fair Lawn NJ
Kenneth James Ward - Basking Ridge NJ

Assignee:

The Block Drug Company - Jersey City NJ

International Classification:

C11D 1704

US Classification:

510192

Abstract:

An improved process for the compression and tabletting of solid sustained release toilet bowl cleaners comprises the addition of a small amount of an anionic surfactant which produces a suitably compressed tablet with controlled rates of dissolution for long term cleaning efficacy. The surfactant allows for the formation of more tightly compressed tablets which require less compression energy expenditures reducing the wear and tear on commercial large scale tabletting machines.
