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).

First claim

What is claimed is:

1. A syringe container comprising:
a container body which stores contents;
a lid base portion which is disposed on a mouth portion of the container body;
a movable lid portion which is disposed to freely move upward to the lid base portion;
an urging means which urges the lid base portion and the movable lid portion in a vertically separating direction; and
a syringe tube which is mounted on the lid base portion and extends toward the container body;
the movable lid portion including:
a mounting cylinder which is mounted on the mouth portion of the container body in a freely attachable and detachable manner,
a lid which is formed to be elastically deformable and closes an upper end opening of the mounting cylinder, and
a cylinder portion which is disposed inside the mounting cylinder in a radial direction and is connected to the mounting cylinder;

the lid base portion including a piston portion which is connected to the syringe tube and is fitted to the inside of the cylinder portion to freely slide up and down;
the cylinder portion being mounted on the syringe tube to freely rise, and the cylinder portion and the syringe tube being formed with engaging portions which engage with each other when the cylinder portion is located at a rising end position with respect to the syringe tube;
an interior of the syringe tube communicating with a space between the upper end opening of the mounting cylinder and the lid;
the cylinder portion being formed with a communication hole through which the interior and the space communicate with each other;
wherein a packing member is disposed between the lid base portion and an upper end opening edge of the mouth portion of the container body, and
a crushing protrusion is formed on a lower surface of the packing member, the crushing protrusion protruding downward and being crushed to an upper end opening edge of the container body, and an overhang recess is formed on an upper surface of the packing member, the overhang recess being at least partially located just above the crushing protrusion.

2. The syringe container according to claim 1 , wherein the packing member is formed with a locking protrusion which is locked with an outer circumferential surface of the upper end opening of the mouth portion of the container body.

3. The syringe container according to claim 2 , wherein the mounting cylinder is screwed into the mouth portion, and is connected to the cylinder portion via a connection, and
the lid base portion engages with the connection when the mounting cylinder rotates about a container axis, and rotates with the movable lid portion.

4. The syringe container according to claim 3 , wherein the movable lid portion comprises an external cylinder which is mounted on the mounting cylinder to be relatively vertically immovable and non-rotatable from an outside in a radial direction, and
the external cylinder exposes the lid upward, while interposing a circumferential edge portion of the lid in the vertical direction between the mounting cylinder and the external cylinder.

5. The syringe container according to claim 2 , wherein the movable lid portion comprises an external cylinder which is mounted on the mounting cylinder to be relatively vertically immovable and non-rotatable from an outside in a radial direction, and
the external cylinder exposes the lid upward, while interposing a circumferential edge portion of the lid in the vertical direction between the mounting cylinder and the external cylinder.

6. The syringe container according to claim 1 , wherein the mounting cylinder is screwed into the mouth portion, and is connected to the cylinder portion via a connection, and
the lid base portion engages with the connection when the mounting cylinder rotates about a container axis, and rotates with the movable lid portion.

7. The syringe container according to claim 6 , wherein the movable lid portion comprises an external cylinder which is mounted on the mounting cylinder to be relatively vertically immovable and non-rotatable from an outside in a radial direction, and
the external cylinder exposes the lid upward, while interposing a circumferential edge portion of the lid in the vertical direction between the mounting cylinder and the external cylinder.

8. The syringe container according to claim 1 , wherein the movable lid portion comprises an external cylinder which is mounted on the mounting cylinder to be relatively vertically immovable and non-rotatable from an outside in a radial direction, and
the external cylinder exposes the lid upward, while interposing a circumferential edge portion of the lid in the vertical direction between the mounting cylinder and the external cylinder.
