Thermo fusible shutter i.e. oval shaped plate, for closing access opening in sheet of body of motor vehicle, is made of polyethylene reticulated so as to be flexible for gluing plate on sheet and rigid for resisting to deformations

摘要

The shutter i.e. oval shaped plate (1), is made of polyethylene to permit the plate to be mechanical resistant, where the plate is fixed on a wall i.e. sheet (2) by using a thermo-fusible agent. The plate is made of mono material and realized from low-density polyethylene based compound and a gluing agent such as ethylene vinyl acetate. The polyethylene is reticulated so as to be flexible for gluing the plate on the wall and rigid for resisting to deformations due to warping and relaxation. Independent claims are also included for the following: (1) a method for forming a shutter (2) a method for closing an opening in a wall of a body using a shutter.
