  • Patent number: 10143623
    Abstract: According to the present invention, a packing member (20) is disposed between a mouth portion (2b) of a container body (2) and a lid base portion (5). A crushing protrusion (20b) which protrudes downward and is crushed to an upper end opening edge of the container body (2) is formed on a lower surface of the packing member (20). An overhang recess (20c) which is at least partially located just above the crushing protrusion (20b) is formed on an upper surface of the packing member (20). After the lid base portion (5), the movable lid portion (6) and the syringe tube (8) are detached from the container body (2), when mounting again, until a crushing protrusion (20b) is crushed, the packing member (20) forms a communication gap (30) between the mouth portion (2b) of the container body (2) and the packing member (20).
