Abstract
Abstract A means of preserving cut flowers placed in water, said means comprising one or more bactericidal substances, with the possible additions of one or more bacteriostatic substances, one or more surfactants, and/or one or more nutritious substances. The bactericidal substance may be 1.3-dichloro-5.5-dimethylhydantoin which splits off chlorine in relation to the pH-value of the aqueous solution. Said derivative forms part of a thin coating applied to the front surface of a strip of paper or cardboard which is very small in relation to the length of the stems of the flowers. A layer of non- (or very little) water-soluble self-adhesive substance is applied to the back surface of the strip, the substance being tolerable by the stems of flowers. The consumer can easily fasten the strip unit close to the lower end of the stem before placing the latter in water. The strip unit is easily dispensible from a protective container.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
73 words
A means suitable for preserving cut flowers in water, said means comprising a support strip, a bacteriostatic substance which splits off chlorine at an increasing rate as the pH value falls as a thin coating on the front surface of the strip and a self-adhesive having at most slight solubility in water on the back surface of the strip, said strip being relatively small compared to the length of stems of the flowers.
Claim 2
Dependent Claim
73 words
A means suitable for preserving cut flowers in water, said means comprising a support strip, a bacteriostatic substance which splits off chlorine at an increasing rate as the pH value falls as a thin coating on the front surface of the strip and a self-adhesive having at most slight solubility in water on the back surface of the strip, said strip being relatively small compared to the length of stems of the flowers.
