Filter-attached cartridge

Provided is a plunger including: a plunger body; a first surface configured to come into contact with an inner peripheral surface of the cylindrical member; a second surface disposed on a base end side relative to the first surface, the second surface having an outer diameter that is smaller than that of the first surface; an outer stepped surface disposed between the first surface and the second surface; a first housing disposed in an area at least partly corresponding to the second surface in the recess, the first housing being provided for housing a tip part of the pin; a second housing disposed on the base end side relative to the first housing, the second housing having an inner diameter that is smaller than a largest inner diameter of the first housing; and an inner stepped surface disposed between the first housing and the second housing.

Plunger, instrument, and mold

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.
