LIVING HINGE CREATION THROUGH VACUUM FORMING OF A THERMOFORMABLE PLASTIC SHEET.

摘要

A bathing vessel is made of a segmented sheet wall of layered materials that includes a first layer of polyurethane material, a second layer of polyurethane material attached to the first layer, a third layer of acrylonitrile butadiene styrene (ABS) material attached to the second layer, and a fourth layer of acrylic material attached to the third layer. The segmented sheet wall has a width a length and a first thickness. The segmented sheet wall has an integral first portion having a second thickness that is that is thinner than the first thickness. The first portion defines a first wall and a second wall in the segmented sheet wall and the first portion is corrugated.
