Liquid medicine dispensing device and dispensing method

The present invention relates to a dispensing device and a dispensing method for a liquid medicine. More particularly, the present invention relates to a dispensing device and a dispensing method for a liquid medicine for storing, transporting, and dispensing a fluid for an electronic industrial drug or the like.

For example, an electronic industrial drug such as a photoresist is stored in a drug container for transportation and then delivered to a manufacturing plant. Such a pharmaceutical container has a recycling method in which the same container is repeatedly used, and a one-way method in which a new container is used each time. In particular, in order not to affect the purity of the high-purity drug, it is preferred to use a container of a non-recycling type, but such a container has a disadvantage of being costly. In recent years, a multi-type storage type container in which the above two methods are combined has been popularized.

Generally, a double storage type container has a pouch (pocket body) formed of a flexible film that has been previously washed. The film bag is formed of an inert material and is disposed in an outer container. When the drug is discharged from the film bag, the film bag is discarded and the drug is to be filled in a new film bag. Then, the outer side container including the joint or the like is repeatedly used.

In the above-described multi-type storage type container, a liquid medicine dispensing device including a liquid medicine container and a dispenser which can discharge the liquid medicine safely and reliably has been invented (for example, see Patent Document 1).

Moreover, the canister for liquid medicine according to the embodiment of the present invention is a non-recyclable container which is discarded after discharging the liquid medicine, and the labor of washing the liquid discharge tube and reloading the bag to the outer container can be omitted. Therefore, compared with the multi-storage type liquid medicine container, there is an overall cost saving advantage.

Next, the operation of the dispenser provided in the liquid medicine dispensing device according to the embodiment of the present invention will be described.

As shown in Fig. 2, in the dispenser 40, the first joint 44, the drain pipe 43, and the second joint 42a are previously inserted into the plug body 41. Further, a joint 45 is connected to the drain pipe 43. As described above, in the dispenser 40 in which the respective elements are integrally formed, the liquid discharge pipe 43 is inserted into the mouth portion 11 of the container 10 as the foremost head (see Fig. 5).

Next, as shown in Fig. 6, the plug body 41 is rotated and fastened to the mouth portion 11 of the container 10, whereby the dispenser 40 can be fixed to the container 10 (see Fig. 5). In the connected state shown in Fig. 7, by loosening the cap nut 44b, the tip end of the drain pipe 43 can be adjusted to abut against the edge of the bottom surface of the inner container 1 (see Fig. 4).

Further, in Fig. 7, by loosening the coupling ring 41r (see Fig. 2), the plug housing 41s (see Fig. 2) can be rotated by an arbitrary angle. At this time, it is preferable to determine the position of the angle of the plug case 41s in such a manner that the cap nut 44b to which the drain pipe 43 is fixed is brought close to the upper edge of the container 10.

In Fig. 7, the tube 42c is connected to the second joint 42a, and an inert gas such as nitrogen gas is supplied from the edge of the tube 42c, whereby the compressed fluid is pressurized to the air layer of the inner container 1 via the ventilating mechanism. The terminal opening 43a supplies the liquid medicine, and the liquid medicine is discharged from the joint 45 via the drain pipe 43 (refer to Fig. 2 or Fig. 4).

The dispenser according to the embodiment of the present invention has a simple configuration, and includes a cylindrical plug body, a ventilating mechanism, and a bent drain pipe, and directly pressurizes the liquid medicine canister via a ventilating mechanism provided in the dispenser Thereby, liquid medicines can be dispensed.

Further, in the investigation of the residual liquid characteristics described below, the pressure of the air layer applied to the inner container 1 was set to "0.5" kgf/cm2 (49 kPa), and the container 10 was filled with ordinary tap water instead of the liquid. The drug was obtained, and the amount of residual liquid at the earliest detection of the bubble from the other end of the drain was determined.

The container 10 to which the previous drain pipe extending straight is connected is placed on a substantially horizontal floor to determine the amount of residual liquid (Investigation A). Further, the front end of the drain pipe in the investigation A was cut at an angle of about 45 degrees. In Survey A, the residual liquid ranged from 650 to 850 g. Further, under the same conditions as above, the liquid discharge tube was cut at a gentle angle of about 45 degrees or less at the tip end to determine the amount of residual liquid (investigation B). In the investigation B, the residual liquid was in the range of 300 to 500 g, and the residual liquid characteristics were slightly improved as compared with the results of the investigation A.

Further, the container 10 to which the previous drain pipe extending straightly is connected is placed on the tilting table 50 (see Fig. 10), and the amount of residual liquid (investigation C) is obtained. Further, the front end of the drain pipe in the investigation C was cut at an angle of about 45 degrees. In the investigation C, the residual liquid was at most 300 g, and the residual liquid characteristics were slightly improved as compared with the results of the investigation B.

On the other hand, the container 10 to which the bent drain pipe 43 of the embodiment of the present invention is connected is placed on the tilting table 50 (see Fig. 10), and the amount of residual liquid (investigation D) is obtained. In the investigation D, the residual liquid was at most 150 g, and the residual liquid characteristics were greatly improved as compared with the results of the investigation C.

In order to distribute liquid medicines.

Next, the action of the tilting table provided in the liquid medicine dispensing device according to another embodiment of the present invention will be described.

In Fig. 18, the bottom surface of the sealed can outer container 716 of Patent Document 1 forms a curved surface that protrudes outward, and the liquid discharge tube 722 can be assembled to reach the bottom surface of the bag 720 conforming to the center of the bottom surface. Therefore, the container 7 of the patent document 1 is a container which is excellent in the so-called residual liquid characteristic in which the residual amount of the liquid medicine in the inside of the pocket 720 is small.

On the other hand, in the container 10 of the can shown in Fig. 1, the bottom surface of the inner container 1 and the bottom plate 23 are flat, and the liquid discharge pipe 46 is assembled so as to be positioned on the bottom surface of the inner container 1 (see Fig. 14). However, if only the container 10 is placed on the ground, the liquid medicine easily remains inside the container. The bottom surface of the inner container 1 is easily formed into a curved surface that is curved outward. However, there is also a manufacturing situation in which it is difficult to provide a plurality of loops for partially adhering to the bottom surface of the inner container 1 bent outward. The outer container 2 is formed in a can shape.

Here, the container 10 is placed by tilting in an attempt to improve the residual liquid characteristics. In Fig. 10, the inclined table 50 formed with the inclined surface 51a inclined at 12 degrees with respect to the horizontal plane is used, and the container 10 is placed obliquely (see Fig. 8). In Fig. 10, it has been confirmed that the liquid medicine does not overflow from the mouth portion 11 when one of the containers 10 is tilted (see Fig. 12). And, the dispenser 40 and the container 10 is connected (refer to FIG. 17), and the aqueous solution filled in the container 10 is dispensed, and as a result, the residual liquid is about 100 g, and the residual liquid characteristic which is substantially the same as the residual liquid of the sealed can of the patent document 1 is formed. When the can is disposed at an inclination angle of less than 2 degrees, the liquid medicine easily remains in the interior of the can. Further, in Fig. 10, the container 10 is formed in a straight truncated cone shape.

In Fig. 11, the inclined table 60 formed with the inclined surface 61a inclined at 30 degrees with respect to the horizontal plane is used to tilt the container 10 (see Fig. 9). In Fig. 11, it has been confirmed that when the container 10 is placed at an inclination angle of more than 30 degrees, liquid medicine may overflow from the mouth portion 11 at one of the inclined positions (refer to Fig. 12). Further, the dispenser 40 is connected to the container 10 (refer to Fig. 17) to dispense the aqueous solution filled in the container 10, and as a result, the residual liquid is about 100 g, and the residual liquid of the sealed can with the document 1 is formed. Roughly the same residual liquid characteristics. Further, in Fig. 11, the container 10 is formed in a straight cylindrical shape.

Next, the action of the liquid discharge pipe provided in the liquid medicine dispensing device according to another embodiment of the present invention will be described.

In Fig. 12 or Fig. 14, in the container 10 of the present invention, the liquid discharge pipe 46 is carefully designed so that the liquid residue characteristics are improved even if the container 10 is placed on a substantially horizontal floor. The terminal opening 46a of the liquid discharge pipe 46 shown in Fig. 12 is cut at an appropriate angle of less than 45 degrees.

In Fig. 12, when the distal end of the liquid discharge tube 46 is cut so as to be orthogonal to the axial direction, the terminal opening 46a is in close contact with the bottom surface of the inner container 1 so that the compressed fluid is directed to the inside. The air layer of the container 1 is pressurized, and it is also difficult to supply the liquid medicine to the terminal opening 46a.

On the other hand, when the tip end of the drain pipe 46 is cut at an angle of 45 degrees or more (long side a = short side b) or more, liquid medicine is easily supplied to the terminal opening 46a, but remains on the bottom surface of the inner container 1. The liquid will increase. By cutting the front end of the drain pipe 46 at an appropriate angle of less than 45 degrees, the residual liquid remaining on the bottom surface of the inner container 1 can be reduced.

Further, in Fig. 14, the drain pipe 46 has a buckling length which is bent at its one end 461 to the bottom surface of the inner container 1. In the embodiment of Fig. 14, the total length of the liquid discharge pipe 46 is 5 mm longer than the previous liquid discharge pipe, and is set to 455 mm.

In the first drawing and the fourteenth to fourteenth drawings, the container 10 is configured to allow the metal top plate 21 to expand and deform when the inside of the inner container 1 is pressurized by the compressed fluid. The reason for this is that, as a transportable can, it is not necessary to increase the weight as compared with the thickness of the thickened outer container 2 and the excessive increase in mechanical strength. When the inner container 1 is stopped from being pressurized, that is, when the inside of the inner container 1 is the same as the atmospheric pressure, the top plate 21 will return to the initial state.

In Fig. 14, a liquid medicine dispensing device according to another embodiment of the present invention is configured such that a buckling phenomenon occurs in the drain pipe 46 within a recoverable range. The liquid discharge pipe 46 of the embodiment is a polyethylene pipe having a diameter of 8 mm and a total length of 455 mm, and buckling can occur in the drain pipe 46 within a recoverable range.

In Fig. 14, when the one end 461 of the liquid discharge pipe 46 is bent to the bottom surface of the inner container 1, the liquid discharge pipe 46 is attached to the container 10, and even if the top plate 21 is expanded, the liquid discharge pipe 46 is The front end can also follow Does not leave the bottom surface of the inner container 1. That is, it is possible to provide a dispensing device for a liquid medicine which is excellent in residual liquid characteristics which is not affected by the expansion of the top plate 21.

The drain pipe 46 shown in Fig. 14 is bent (buckling) on the bottom surface of the inner container 1 so as not to block the terminal opening 46a. Further, it is preferable that the drain pipe 46 is provided with a larger diameter in the weak axis (bending) direction of the drain pipe 46 so as not to block the terminal opening 46a depending on the manner of mounting the drain pipe 46. Forming of an arc.

The modified drain pipe 46 and the previous drain pipe (not shown) are respectively attached to the container 10, and the amount of the residual liquid is compared. As a result, it is found that the residual liquid amount of the previous drain pipe is 650~ 850g, in contrast, the residual liquid volume of the improved drain pipe 46 is 300 to 500 g, so the amount of the residual liquid is greatly reduced.

In addition, in the investigation of the residual liquid characteristics, the pressure of the air layer applied to the inner container 1 is set to "0.5" kgf/cm2 (49 kPa), and general tap water is filled in the container 10 instead of the liquid medicine. The amount of residual liquid at the earliest detection of the bubble from the other end of the drain pipe was determined. Further, the container 10 is placed on a substantially horizontal floor.

In the liquid medicine dispensing device according to another embodiment of the present invention, one end of the liquid discharge pipe that reaches the bottom surface of the inner container is configured to cut the front end of the liquid discharge pipe at an appropriate angle of less than 45 degrees, and the liquid discharge pipe One end has a buckling length which is bent to reach the bottom surface of the inner container, and thus it has been confirmed that even if the container 10 is placed on a substantially horizontal floor, the liquid medicine can be prevented from remaining. If you use a tilting table, you will get the residual liquid characteristics into one. Step improvement.
