Method of manufacturing metallized thermoplastic flower pot cover |
摘要 |
The present invention pertains to an improved method for rapidly forming a decorative container for use as a covering for a similarly shaped object, which method comprises: (a) providing a thin sheet of metallized thermoplastic heat shrinkage polymer material; (b) optionally imprinting a design or other matter upon the sheet of polymer; (c) optionally cutting said sheet to the dimensions approximating the dimensions of the base and side walls of said object; (d) placing the sheet over a heated form having a temperature of between about 80 DEG and 110 DEG C. (e) placing a complementary heated form also having a temperature of between about 80 DEG and 110 DEG C. (f) fitting the heated forms of substep (d) and (e) together having the thermoplastic sheet therebetween; (g) maintaining the temperature of between about 80 DEG and 100 DEG C. between the forms for between 1 and 10 minutes until said sheet folds under the influence of the heat within the space between form and its complementary form; (h) removing the formed container from the heated form; and (i) cooling the formed shaped object which retains its shape without chemical adhesive or mechanical supports. Preferably, the polymer material is a metallized heat shrinkable polyvinylchloride.
