Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
102 words
The method of producing plastic greenery for decorative purposes, such as artificial parsley, comprising molding in plastic an elongated member from which project a plurality of sprigs of stems and buds spaced along the member with the stems and buds generally parallel to each other; passing the elongated member and interconnected stems and buds through a hot water spray to soften and reorient the stems and buds; and comprising the said stems and buds between two moving platens until the plastic cools to allow the stems and buds to be repositioned into conically-shaped interfering shapes; whereby the plastic greenery resembles real greenery.
Claim 2
Independent Claim
102 words
