Abstract: PROBLEM TO BE SOLVED: To avoid discoloring due to light and heat, suppress the growth of miscellaneous bacteria and keep the freshness of vegetables by involving a vegetable storage with a Cu-based bactericide-contg. resin lid covering its top face. SOLUTION: This vegetable chamber 1 of a refrigerator is composed of a polypropylene-made vegetable storage 2 and polystyrene lid 3 which is closely contacted to the top face of the vegetable storage 2. A Cu-based bactericide 4 is contained by e.g. 1 wt.% kneading in the lid 3. As the lid 3 of the involved vegetable storage 3 in the vegetable chamber of the refrigerator contains the Cu-based bactericide 4, the growth of miscellaneous bacteria can be suppressed, without discoloring by light and heat.

Abstract: PURPOSE: To prevent a bad external appearance from being formed owing to an anti-fungus agent by blending an anti-fungus agent having a particle diameter less than a specific value in resin made in-refrigerator parts in a refrigerator. CONSTITUTION: An anti-fungus agent 2 is blended in ABS resin 1. The anti- fungus agent 2 carries an anti-fungus component 4 using silica gel 3 as a base material. A particle diamenter of the base material of the anti-fungus agent 2 is made smaller than 20μm whereby even if the base material absorbs water, the degree of expansion of the base material is small. Further, the base material is prevented from being expanded by covering the anti-fungus agent 2 with hydrophobic resin and hence reducing water absorption in the base material.j Even if the resin is expanded owing to the water absorption of the base material of the anti-fungus agent 2, the expansion is returned to the original size if water disappears.
