Element of contenance of expanded materials used for wall insulation, especially of refrigerators

摘要

Element of contenance of expanded materials used for the walls insulation expecially of refrigerators; this element of contenance 1 is formed of a cover made of fabric conformed to the basin 2 of the refrigerator, anyway with bigger dimensions to the thickness of the interplace of insulation. This cover is fixed with its margin to the correspondent perimetral margin 23 of the basin 2 and it presents in correspondence with the usual introduction point point of the expanded material, the tube 12. The assembling of the basin 2, covered by the element of contenance 1 and of the other components of the cold store takes place as usually but the expanded material is injected through the mentioned tube 12 in the space resulting between the walls of basin 2 and the cover of the element of contenance 1 to adhere the same to the opposite walls of contenance. The application of the element of contenance 1 prevents the outcoming of the expanded material and the subsequent forming of slabbers in the critical areas. <IMAGE>
