Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drug solution container for containing a liquid such as a drug, and more particularly to a drug solution container in which a container body is double-stopped with an inner lid and an outer lid.

[0002]

2. Description of the Related Art Various industrial chemicals are stored in containers, but when nitrogen gas or volatile gas is generated from the chemicals, air is used as an inner lid to prevent the container from swelling or bursting. A cap is used. Further, such a deoxidizing agent or the like that deteriorates in performance when it comes into contact with oxygen in the atmosphere does not use such an air bleeding cap, and is hermetically sealed to shield it from the outside air.

[0003]

However, when the chemical solution is once opened and the chemical solution is injected even if the stopper is tightly closed, and the chemical solution remains in the container for the next use, the atmosphere inside the container at the time of the chemical solution injection. If it penetrates and is sealed in that state, the atmosphere (oxygen) in the container reacts with the chemical liquid, causing a pressure drop and deforming the container. Further, if the container is tightly closed, unevenness will occur in the container due to a change in temperature even if it is not an oxygen absorber. In recent years, due to the trend of resource saving, this type of container is being used repeatedly, and deformation of the container hinders reuse. On the other hand, when an ordinary air-bleeding cap is used, the chemical solution may come into contact with air at the distribution stage, the chemical solution may deteriorate, and the chemical solution may leak from the opening of the cap, which is a safety and health problem.

The present invention was developed in order to solve the above-mentioned problems, and a sealed stopper that has been used in an unopened state can be used as an inner lid as it is even after being opened, and the inner lid and the outer lid are doubled. It is an object of the present invention to provide a drug solution container and its inner lid that do not swell or dent due to residual liquid of the drug solution during use or temperature changes even when the container is plugged.

[0005]

According to a first aspect of the present invention, there is provided a container for chemical liquid, which has a bottomed cylindrical container main body in which an inlet cylinder portion having an opening is provided at one end and which stores the chemical liquid, and a bottomed cylinder provided with a flange. A handle is provided on the inner bottom surface, a thin portion is provided on a part of the periphery of the base of the handle, and a flexible inner lid capable of breaking the thin portion by pulling the handle to form a slit, It is configured with an outer lid of a bottomed cylinder which is engaged with and covers the inlet tube portion of the container body, and a bottomed portion protruding from the flange of the inner lid is fitted in the tube of the inlet tube portion of the container body. It is configured such that the opening of the container body is closed and the inlet tube portion of the container body is covered with the outer lid to be engaged with the inlet tube portion. The inner lid of this drug solution container has a handle on the bottom surface of a bottomed cylinder with a flange, and a thin portion is provided around a part of the base of the handle, and the thin portion is broken by pulling the handle. In addition, it is flexible because it can form slits (including round and square openings) through which gas can flow.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic view of a container for liquid medicine after opening according to an embodiment of the present invention, FIG. 2 is a top view of an inner lid after opening in this embodiment, and FIG. 3 is AA of FIG.
Sectional drawing, FIG. 4A is a sectional view of the inner lid of FIG. 2, and FIG. 4B is an enlarged view of a portion indicated by B in FIG. 4A.

In FIG. 1, a container body 1 is a bottomed container in which an inlet tube portion 3 having an opening 2 at one end is formed, and a male screw 4 is formed on the outer peripheral surface of the inlet tube portion 3. Inner lid 10
Is made of a flexible material and is formed into a bottomed cylindrical shape having a flange 11 and a shallow bottom. On the bottom surface 12 inside the cylinder of the inner lid 10,
A handle 13 is provided integrally with the bottom surface 12. On the back surface of the bottom surface 12 in the cylinder, a groove portion 14 is formed on the back surface of the base of the handle 13, and a thin portion 14a is provided at the base of the handle 13.

A ring 13a is formed on the free end of the handle 13, and the handle 13 can be pulled by putting a finger in the ring of the ring 13a. Further, a gas vent groove 16 is formed on the opening surface 15 side across a part of the ring of the flange 11 forming the outer peripheral portion of the opening surface 15 of the bottomed cylinder having a shallow bottom. The outer lid 20 is formed in a bottomed cylindrical shape with a shallow bottom,
A female screw 21 is formed on the inner peripheral surface of the cylinder, and is formed so as to be screwed with a male screw 4 formed on the outer peripheral surface of the inlet cylinder portion 3 of the container body 1.

The unopened drug solution container 50 before use is
For example, an oxygen absorber that causes performance deterioration when contacted with the atmosphere is filled, and a bottomed portion protruding from the flange 11 of the inner lid 10 is fitted into the cylinder of the inlet tube portion 3 of the container body 1 to open the container body 1. Block 2 Then, the inner peripheral surface of the tube of the outer lid 20 is engaged with the inlet tube portion 3 of the container body 1 to cover the container body 1 with the outer lid 20.

When the unsealed chemicals container 50 is opened, the outer lid 20 is rotated to release the engagement (screw) between the inlet tube portion 3 of the container body 1 and the outer lid 20 and remove the container body 1 from the container body 1. Lid 2
Remove 0. Next, with the outer lid 20 removed, put a finger in the ring of the ring 13a at the free end of the handle 13 of the inner lid 10 and pull the handle 13 to remove the inner lid 10 and the position of the base of the handle 13. The thin portion 14a formed by providing the groove portion 14 on the back surface of the is broken to form a slit 17 in a part of the periphery of the base of the handle 13. Slit 17
The size of is such that the passage of gas is possible but the passage of liquid is as small as possible. Thus, even if the drug solution remains in the drug solution container or becomes empty, first, the inner lid 10 is fitted into the inlet tube portion 3 of the container.

Further, an outer lid 20 is attached to the inlet tube portion 3 of the container body 1.
Cover and rotate to cover the inlet tube portion 3 of the container body 1 with the outer lid 20.

In the state where the inlet tube portion 3 of the container main body 1 is covered with the outer lid 20, the flange 11 of the inner lid 10 is in pressure contact with the peripheral edge portion 20b of the bottom surface 20a of the bottomed tube of the outer lid 20. Since the gas vent groove 16 is formed across a part of the ring of the flange 11 of the inner lid 10 that comes into contact with the peripheral edge portion 20b of the bottom surface 20a of the bottomed tube, the gas vent groove 16 and the outer lid are formed. A gap is formed between the bottom surface 20 a of the 20 and the peripheral edge portion 20 b. Further, in a state where the inlet tube portion 3 of the container body 1 is covered with the outer lid 20, the passage state of the gas in the slit 17 of the inner lid 10 is ensured, and the container body 1
A gap is formed by the slit 17 between the inlet tube portion 3 and the inner lid 10, and a gap is formed by the gas vent groove 16 between the inner lid 10 and the outer lid 20. Therefore, when the container body 1 is doubly plugged with the inner lid 10 and the outer lid 20, a gap communicating with the outside air is formed through the slit 17 and the gas vent groove 16.

Thus, even if the pressure inside the container changes due to changes in temperature or chemical concentration, the pressure is compensated through the screw-threaded portion, the gas vent groove 16 and the slit 17, so that the container is deformed. Will not occur.

[0013]

As described above in detail, according to the liquid medicine container of the present invention, the airtight cap that is used in the liquid medicine container in an unopened state is processed into an air bleeding cap by a simple operation after opening. Then, the inner lid used in the unopened state can be used as it is. Even when the outer lid is covered, the inner lid functions as an air bleeding cap, and a gap is formed between the outer lid and the inner lid. Therefore, even if the inner lid and the outer lid are double-sealed after opening, the liquid filled in the liquid medicine container has a gap that communicates with the outside air, and therefore, due to the residual liquid during use and the temperature change, It has excellent effects such as no bulging or denting of the container.
