The material of the containers 1 and 2 is polypropylene, polyethylene, polystyrene, polytetrafluoroethylene, acryl, glass, aluminum, stainless steel or the like, for instance. By providing many holes 5 in the bottom of the main body 2 of the containers, the containers 1 and 2 are made to have a function of removing foreign substances. While the shape of the section of the hole 5 may be columnar or of a square pillar, the hole may also have a structure facilitating the removal of the foreign substances inside the containers, by tapering the hole so that the opening inside the main body 2 of the vessels is large and the opening outside this body smaller.</p> |
