摘要： A container includes a container main body including a housing part and an opening, and a lid configured to close the opening and including an insertion part configured to be inserted to the opening. The outer peripheral surface of the insertion part includes first and second protrusions and first and second recesses. The inner peripheral surface of the opening includes third and fourth protrusions and third and fourth recesses. When the insertion part is temporarily inserted to the opening, the third protrusion presses the first recess in a state where the first protrusion is housed in the third recess. When the insertion part is fully inserted to the opening, the third protrusion presses the second recess and the fourth protrusion presses the first recess in a state where the first protrusion is housed in the fourth recess and the second protrusion is housed in the third recess.

摘要： Provided is an inexpensive mesh filter with high productivity. This mesh filter, which is an integrally molded product of resin, includes: a mesh part in which a plurality of ribs are disposed in a lattice shape; a rim part which is formed in an annular shape so as to surround the mesh part, and to which the plurality of ribs are connected; and a final filling part which is disposed on the inner side of the rim part, and to which some of the plurality of ribs are connected. The cross-sectional area of at least one rib among the ribs connected to the final filling part is smaller than the cross-sectional area of at least one rib among the ribs not connected to the final filling part.
