JPS6449963A - Container wherein liquid is prevented from being concentrated - Google Patents

Abstract

PURPOSE:To reduce the vaporization of a solvent without making it inconvenient to take the liquid out by providing a member which can floats on the liquid surface, has a hole reaching the liquid surface in the center or at its periphery, and covers at least a half of the liquid surface in the liquid container. CONSTITUTION:The float member 5 is provided in the container main body 1 whose opening area is large, the liquid 4 is put in, and the inside is sealed with a lid 2. The float member 5 is normally in a plate shape as a preferable shape, but may be conic. This member is preferably to be as small as passible in the gap to the internal surface of the liquid storage part of the container while floating on the liquid surface. When the contour is similar to the inside shape of the container, the gap to the internal wall of the opening part is reducible. When the container is made of a material larger in specific gravity than the liquid, a hollow part is formed so as to make the bulk specific gravity smaller than the specific gravity of the liquid. The material of the float member 5 need to be selected so that the liquid composition is not affected.
