Description

DETAILED DESCRIPTION OF THE INVENTION The present invention completely seals not only the outer surface of the rubber stopper for medicine bottles, but also the inner surface within the micropores under the epidermis, without causing any change in the quality of the rubber stoppers for medicine bottles. This relates to a method for washing, sterilizing, and drying a rubber stopper for medicine bottles, in which purified water is supplied into a bonito body in which the rubber stopper for medicine bottles is housed, and the canned crab is washed, sterilized, and dried. The inside of the body is depressurized for an appropriate period of time and then brought to normal pressure for an appropriate period of time, and this process of switching from reduced pressure to normal pressure inside the body is repeated an appropriate number of times, followed by a defoaming and washing process, and the can is heated to a temperature at which the entire rubber band for medicine bottles does not deteriorate. A foreign matter removal step in which the temperature of the washing water inside the crab body is raised and the temperature is maintained for an appropriate period of time before being drained; and after the rubber stopper for the drug bottle is washed vertically with running water in the body for a desired period of time. , a rinsing step in which the process of running vertically with running water and draining the drain is carried out an appropriate number of times, and high-pressure steam at a temperature and pressure that does not deteriorate the rubber stopper for the medicine bottle is supplied into the body. A method for vertically washing and sterilizing rubber stoppers for medicine bottles, which comprises a high-pressure steam sterilization step in which the rubber stoppers for medicine bottles are sterilized, and the rubber stoppers for medicine bottles are constantly exposed to light during the entire process, and the above-mentioned method. After the high-pressure steam sterilization process, the pressure inside the bonito shell is reduced while the rubber stopper for medicine bottles is tied up, and hot air at a temperature that does not cause deterioration of the rubber stoppers for medicine bottles is passed through the inside of the bonito body to dry the rubber stoppers for medicine bottles. The method of washing, sterilizing, and drying rubber stoppers for medicine bottles that includes a drying process, as well as the rinsing process and high-pressure steam sterilization process in the above-mentioned method, allows the rubber stoppers for medicine bottles to be washed while being washed. A silicone coating process is performed in which silicone liquid is sprayed into the body of the sparrow to siliconize the entire surface of the rubber cap for medicine bottles, and the rubber stopper for medicine bottles is washed vertically with running water inside the body for an appropriate period of time, and then the rubber stopper for medicine bottles is washed vertically with running water inside the body of the mantis. The present invention is characterized by providing a device for washing, sterilizing, and drying a rubber stopper for a drug bottle, which includes a final washing step in which drainage is performed.

Rubber stoppers, which are generally used as parts of medical bottles for medicines, medicinal solutions, etc., have a slightly rough surface, and their shapes include simple cylindrical rubber stoppers, as well as half-bottomed stoppers. Long rubber stoppers and rubber stoppers for infusions have complex shapes with air vent holes, etc., and when using these stoppers, there is a problem that they must be thoroughly washed and sterilized.

Conventional methods of washing rubber stoppers for medicine bottles that have been generally carried out include washing using a vertical washer, in which the rubber stopper for medicine bottles is simply immersed in water, and washed completely, or high-pressure washing. A high-pressure jet washing method in which a jet stream is sprayed onto the rubber stopper for medicine bottles to wash the liquid, or an ultrasonic method in which the rubber stopper for medicine bottles is housed in an ultrasonic washer and the rubber stopper for medicine bottles is cleaned using ultrasonic waves. Sonic washing methods are used.

However, with the washing liquid using the lacquer washer, in the case of complex shapes with air holes, such as long-legged rubber stoppers for half-filling or rubber stoppers for infusions, the outer surface is particularly difficult to clean, as is the inner surface of the small hole. It is difficult to wash fine details vertically, and even with the high-pressure jet washing method, when washing a large number of rubber stoppers for medicine bottles at once, the jet stream is never sprayed evenly over the entire stopper body. Even when using a single rubber stopper for a medicine bottle, not only is it difficult to wash the liquid evenly due to differences in the amount of water that hits the bottle, but also
Microscopic air bubbles under the epidermis and microscopic air adhering to the surface layer could not be completely removed, resulting in omissions in the washing of chicks in these areas.

Furthermore, in the ultrasonic rice bran cleaning method, the entire rubber coating for medicine bottles itself has elasticity, so the sound waves are absorbed by its soft surface and the cleaning effect is hardly achieved. There wasn't.

In addition, in the sterilization method after washing all the rubber bottles for medicine bottles, the high-pressure steam sterilization method is used to sterilize all the rubber bottles for medicine bottles, etc.
3 When sterilizing powder, the rubber becomes viscous, and when it dries, the rubber stoppers for medicine bottles often stick to each other.To prevent this, the temperature of the steam should be lowered. However, if the sterilization time is shortened, sterilization may become insufficient.

Furthermore, there are various problems with the method of drying rubber stoppers for medicine bottles after sterilization. In other words, in the commonly used vacuum drying method, when the temperature of the rubber stopper for medicine bottles decreases, only the radiation heat from the jacket conducts heat. If it seems dry,
The degree of drying is extremely poor, and not only does it cause large variations in drying locally, such as between the rubber bottles and within the microscopic pores of the rubber bottle stoppers, but also the rubber stoppers for medicine bottles dry 12 times during the sterilization process.
If the pressure of water that has risen to about 0q○ is rapidly reduced to, for example, 174 Kg/Hg, the boiling point of water will rapidly drop to about 300, so water that has landed on the surface of the rubber seal for medicine bottles will drop. (steam drain) evaporates, and its latent heat of vaporization causes the temperature of the rubber stopper for the medicine bottle to drop significantly.

This means that, for example, although the rubber stopper for medicine bottles itself has been heated to 120 to 13,000, which is the sterilization temperature in the sterilization process, and has become soft and viscous, if it is suddenly cooled in the drying process. This causes the rubber caps for medicine bottles to stick to each other and deteriorates the quality of the rubber.At least on the surface, the rubber stoppers for medicine bottles harden instantly due to the low temperature, increasing their hardness and impairing the properties of the rubber. This means damage to the medicine bottle, and also promotes wear and dust generation due to mutual friction between the rubber stoppers for medicine bottles.
This indicates that this is not a desirable method for drying rubber stoppers for medicine bottles.

As described above, conventional methods of cleaning, sterilizing, and drying rubber stoppers for medicine bottles have produced unfavorable results depending on the type of rubber stopper for medicine bottles.

The present invention was completed as a result of various experiments and research in order to eliminate the various drawbacks of the conventional methods mentioned above.

The following is an example of how a rubber stopper for a medicine bottle is washed, sterilized, coated with silicone, and dried using the apparatus for washing, sterilizing, and drying a rubber stopper for a medicine bottle configured as described above. It will be explained along with its action.

Before operation of the device, all solenoid valves are closed, pumps and blowers are stopped, and the motor is also stopped.

In this state, both the opening and closing doors 1 and 2 are opened, the basket 7 is taken out from the rotating drum 6, and the rubber stopper for the medicine bottle to be washed is placed in the basket 7, which is about 1/2 of the capacity of the basket 7.
After the three assets are contained, the lid is placed on the rotating drum 6 again.
The cotton is fixed by a cotton belt 8 to the opening/closing doors 1 and 2.
is closed.

'1) Defoaming and vertical washing process The solenoid valve 20 is opened, and after the washing liquid water is supplied to the extent that the entire basket 7 in the inner cylinder 3 is submerged, the solenoid valve 20 is closed and the motor 10 is driven. The rotating drum 6 is rotated underwater.

The rotation of the rotary drum 6 is continued once until the end of the final process (drying process). p. m. It is constantly rotated at a speed of .

As the rotary drum 6 rotates, the rubber stopper for the medicine bottle is entrained in the basket 7, and is washed with liquid to remove adhering dust and the like from the surface.

After this normal pressure state continues for 4 to 5 minutes, the solenoid valve 27 is opened, the vacuum pump 25 is activated, and the inside of the inner cylinder 3 is heated at a pressure of -1,300 to -1,600 depending on the shape of the rubber stopper for the pill bottle. The pressure is reduced to 1'Hg, that is, to a pressure at which the washing water in the inner cylinder 3 does not boil, and this reduced pressure state is continued for 4 to 5 minutes.
By continuing this depressurized state, the fine air adhering to the entire surface of the medicine bottle rubber stopper immersed in the washing water and the residual air under the skin are removed, and the surface of the medicine bottle rubber stopper is completely covered with the washing liquid. immersed in water. After the pressure reduction state continues for the predetermined time, the solenoid valve 27 is closed, the operation of the vacuum pump 25 is stopped, and the solenoid valve 41 is opened, and the low-pressure blower 38
is activated, air is sent into the inner cylinder 3, and the inside of the inner cylinder 3 is brought to normal pressure. When the inside of the inner cylinder 3 is brought to normal pressure, the solenoid valve 41 is closed, the operation of the low pressure floor 38 is stopped, and after the normal pressure inside the inner cylinder 3 is maintained for 4 to 5 minutes as before, the same as above Then, the pressure is reduced again.

This process of switching from normal pressure to reduced pressure inside the inner cylinder 3 is repeated to remove bubbles.
The number of repetitions of the normal pressure → reduced pressure switching process in the vertical washing process is:
It is determined as appropriate depending on the shape and size of the rubber stopper for medicine bottles, the degree of contamination, etc. '2' Foreign matter elution step After the defoaming and washing steps are completed, the solenoid valves 15 and 48 are opened, and 1.02 liters of water is injected from one side 14a of the high-pressure steam supply pipe in advance depending on the shape of the rubber stopper for the medicine bottle, etc. High-pressure steam that has been reduced and regulated to a predetermined pressure of ~2.0 kg/unit is supplied into the outer cylinder 4, and the entire solid body A is flooded to 120 to 1300 C, while air, Dry steam that does not contain the liquid separated is supplied into the inner cylinder 3 through the steam filter 47, and the washing water in the inner cylinder 3 is heated to a temperature of 120 to 13,000, which is a temperature at which the rubber stopper for medicine bottles does not deteriorate. The temperature is raised and this temperature raised state is continued for 20 to 3 minutes to carry out the foreign matter elution step.

Even in this process, the rubber stopper for the medicine bottle is constantly rotated, so that the rubber plasticizer, dirt, etc. on the entire surface of the rubber stopper for the medicine bottle and under the skin are effectively drawn out into the washing water.

When the foreign matter elution process is completed, the solenoid valves 15 and 48 are closed, and the solenoid valves 31 and 32 are opened, so that the washing water in the inner cylinder 3 and the drain in the outer cylinder 4 are drained into the respective drain pipes 33 and 34. The water is then discharged to the outside through the main drainage exhaust pipe 28.

{3} Port washing step After the above drainage, only the solenoid valve 31 of the drain drain pipe 33 opened in the inner cylinder 3 is closed, and the solenoid valve 31 of the drain drain pipe 34 opened in the outer cylinder 4 is closed. Valve 32 remains open, solenoid valves 16, 19, and 35 are opened, and solenoid valve 1 remains open.
5 is opened and closed intermittently, the temperature inside the heat exchanger 17 is raised by high-pressure steam, and by passing through the heat exchanger 17, pure water raised to 80 OO is supplied into the inner cylinder 3. Water is drained from the overflow pipe 36 connected to the side wall of the cylinder 3, and during this time, the rubber stopper for the drug bottle is placed in the basket 7 and rinsed with running water, and high-pressure steam is temporarily pumped into the outer cylinder 4. By being supplied, the temperature of the flowing water in the inner cylinder 3 is prevented from decreasing, and the drain generated in the outer cylinder 4 is discharged from the drain drain pipe 33 to the outside of the bonito body.

After the overflow hot water rinsing continues for 5 to 10 minutes, the electromagnetic valves 19 and 35 are closed to stop the supply of pure water, and at the same time the overflow pipe 36 is blocked.
The solenoid valves 31 and 41 are opened, the low pressure blower 38 is operated, and outside air is supplied into the inner cylinder 3, and the drain drain pipe 33
The water for rinsing the Naito 3 passes through the main drainage exhaust pipe 28 and is discharged to the outside of the bonito body.

When the drainage is completed, the solenoid valves 31 and 41 are closed, and the solenoid valves 19 and 35 are opened again to repeat the overflow warm water rinsing.

At the end of the overflow wash in this rinsing process, dirt, rubber particles, residual detergent, dust, etc. adhering to the rubber stopper for medicine bottles are removed, and they settle on the inner bottom surface of the inner cylinder 3 by drainage. Relatively large specific gravity dust, fine metal powder, etc. are discharged outside the fin body.

The number of repetitions of this rinsing step is appropriately determined depending on the size, shape, etc. of the rubber stopper for the drug bottle.

'4) Silicone coating process After the final drainage in the rinsing process is performed and the solenoid valves 19 and 35 are closed, the solenoid valve 53 is opened, the high pressure pump 51 is activated, and the silicone in the silicone liquid tank 52 is The liquid is supplied in the form of a mist from the nozzle 49 of the sprayer 50 into the inner cylinder 3, and the inner cylinder 3 is filled with the liquid.

Since the rubber stopper for medicine bottles is rotated in the basket 7 of the rotating drum 6, even the details of the rubber stopper for medicine bottles are siliconized.

In this silicon coating step, the solenoid valve 15 is also opened and closed intermittently to supply high pressure steam into the outer cylinder 4, and the temperature inside the inner cylinder 3 is maintained at 8,000.

When the silicon coating process is completed, the solenoid valve 54 is closed and the operation of the high pressure pump 51 is also stopped.

[5} Final rinsing process After the silicon coating process is completed, the solenoid valves 19 and 29 are opened, and as in the case of the rinsing process, pure water heated to 80°C in the heat exchanger 17 is supplied from the refined water supply pipe 18, as in the rinsing process. is supplied into the inner cylinder 3, and at the same time, a final washing process is carried out in which washing liquid waste water is discharged from an overflow pipe 30 connected to the upper wall of the inner cylinder 3.

During the final washing with flowing hot water for a predetermined time of 5 to 1 minutes, the overflow water is drained from the upper wall of the inner cylinder, so the inner cylinder 3 is filled with pure water, and the rotating drum 6 and basket 7 Dirt, etc. adhering to the surface of the water is also completely washed away.

Even in the final washing step, the solenoid valve 15 is opened and closed intermittently to supply high-pressure steam into the outer cylinder 4 intermittently, thereby preventing the temperature of the washing water in the inner cylinder 3 from dropping. When this final washing step is completed, the solenoid valves 16, 16, 19, 29, 32 are closed, and high pressure steam is supplied to the inside of the outer cylinder 4 and the heat exchanger 17.
The supply of refined water into the inner cylinder 3, the overflow from the top wall of the inner cylinder 3, and the drainage from the bottom of the outer cylinder 4 are stopped, and at the same time, the solenoid valves 31 and 41 are opened, and the low-pressure blower 38 is activated. Outside air is sent into the inner cylinder 3, and the washing water in the inner cylinder 3 is discharged from the drain pipe 33 to the outside of the body.

When the discharge of refined water in the inner cylinder 3 is completed, the low pressure blower 38
operation is stopped, and the solenoid valves 31 and 41 are closed. {
6} High-pressure steam sterilization process After the final refinement process is completed, the solenoid valve 15 is opened and high-pressure steam is supplied into the outer cylinder 4 from one side 14a of the high-pressure steam supply pipe, and the entire can crab body A is heated to 120 to 130°C. At the same time as the overflow, the solenoid valve 48 is also opened and closed intermittently, and the high-pressure dry steam, which does not contain condensate and which has been separated into gas and liquid in the outer cylinder 4, passes through the steam filter 47 and flows into the inner cylinder 3 intermittently. This high-pressure dry steam sterilizes the rubber stopper for the medicine bottle.

After 20 to 30 minutes of steam sterilization, the solenoid valve 48 is closed, and at the same time the solenoid valve 15 is opened and closed intermittently.
The solenoid valves 31 and 32 are opened, and the drain in the inner cylinder 3 and outer cylinder 4 is drained. After the drainage is completed, only the solenoid valve 31 of the drain drain pipe 33, which is closed in the inner cylinder 3, is closed, and the high pressure steam sterilization process is completed. is completed.

'7) Drying process When the high-pressure steam sterilization process is completed, the solenoid valves 41 and 44 are opened, and the low-pressure blower 38, heater unit 39, and high-pressure blower 43 are operated.

The heater unit 39 used is one that raises the temperature of outside air taken in by the low-pressure blower 38 to 8,000 ℃.

The electromagnetic valve 15 is opened and closed intermittently, high pressure steam is intermittently supplied into the outer cylinder 4, the inside of the outer cylinder 3 is maintained at 100°C, and a drop in temperature in the inner cylinder 3 is prevented.

The difference between the air supply volume of the low-pressure blower 38 and the exhaust volume of the high-pressure blower 43 is such that the inside of the inner cylinder 3 has a negative pressure of -300 to 180 m/Aq depending on conditions such as the shape of the rubber stopper for the medicine bottle. It is determined in advance.

The outside air which has been removed by the pre-treatment filter 37 and taken in by the operation of the low-pressure blower 38 is heated to 8,000 ℃ by the heater unit 39, is further made sterile by the paper filter 40, and is supplied into the inner cylinder 3. Dry the rubber stopper for medicine bottles that is heavily contaminated inside the inner cylinder 3, and
The air is exhausted from the exhaust pipe 45 to the outside of the body.

Here, due to the difference in displacement between the low-pressure blower 38 on the air supply side and the high-pressure blower 43 on the exhaust side, there is a negative pressure inside the inner cylinder 3, forced air drying, and Because the rubber stopper is constantly being rubbed, the surface of the rubber stopper for medicine bottles, including the area under the epidermis, is completely dried, and the inner tube 3
The water droplets falling into the inner cylinder 3 instantaneously turn into water vapor, and this water vapor is also forcibly exhausted from the inner cylinder 3, so that drying is carried out efficiently. Although it varies depending on the shape, size, quantity, etc. of the rubber stopper for medicine bottles, a sufficient degree of dryness can usually be obtained in 40 to 60 minutes.

When the drying process is completed, the solenoid valves 15, 31, and 32 are closed, the operation of the heater unit 39 is stopped, and the supply of high-pressure steam into the outer cylinder 4 is stopped, and the drains of the inner and outer cylinders 3 and 4 are stopped. At the same time as the drain pipes 33 and 34 are closed, sterilized outside air at normal temperature is supplied into the inner cylinder 3 by the low-pressure blower 38, and the rubber stopper for the medicine bottle, which is closed, is cooled to room temperature. The warm air inside the inner cylinder 3 is discharged to the outside of the beard body by the high-pressure blower 43.

When this cooling process is completed, the operation of the high pressure blower 43 is first stopped, the solenoid valve 44 is closed, and after the inside of the inner cylinder 3 is brought to normal pressure, the operation of the low pressure blower 38 is stopped,
The solenoid valve 41 is closed, and the motor 1 for driving the rotating drum 6 is closed.
The rotation of 0 is stopped and the entire process is completed.

Thereafter, the doors 1 and 2 are opened, the basket 7 is removed from the rotating drum 6, and the sterilized rubber stopper for a medicine bottle is taken out from inside the basket 7.

However, since this cooling process is not the purpose of the present invention, it is free to use a conventional water cooling method or air cooling method, or to install a dehumidifier.

In addition, in this example, an apparatus consisting of the above-mentioned apparatus is shown to be used in the above-mentioned method, but the number of repetitions of the process, time, temperature, pressure, capacity, type, etc. of the constituent apparatus during use are as follows: Purpose of use of rubber stoppers for medicine bottles,
Determined empirically based on quality, size, shape, type, quantity, etc.

Further, as described above, the order of each step in the washing, sterilizing, and drying methods for the rubber stopper for medicine bottles and the omission of steps can be easily changed as appropriate depending on the purpose of use of the rubber stopper for medicine bottles.

Since the present invention is comprised of the above-mentioned method, defoaming, washing lacquer, elution of foreign matter, rinsing, sterilization, drying, etc. are performed evenly and sufficiently down to the epidermis without causing any deterioration of the rubber stopper for medicine bottles. At the same time, rubber stoppers for medicine bottles are constantly polished, sterilized, and dried in a dry state, so even if the rubber stoppers for medicine bottles, which become viscous at high temperatures, are sterilized at a high temperature to that limit and then dried, the rubber stoppers for medicine bottles become viscous. The entire structure will not become loose or weakened, and no bubbles will be removed.
During the washing process, high-pressure steam sterilization process, silicone coating process, final washing liquid process, and drying process, even if a large number of rubber stoppers for medicine bottles are placed in a basket, etc., there will be unevenness even if they are placed in the top, bottom, left or right position. During the process of defoaming, washing liquid, silicone coating, final washing liquid, sterilization, and drying, foreign matter elution process and rinsing process, foreign substances and dirt that are eluted and attached to the surface of the rubber camphor for medicine bottles are removed from the rubber stopper for medicine bottles. The whole process is carried out with high efficiency, such as being easily separated from the washing liquid and water.

Next, the effects of each step in the method according to the present invention will be described separately as follows. In other words, in the defoaming and washing process, the process of reducing the pressure inside the rock body and then changing it to normal pressure is repeated while the rubber stopper for medicine bottles is being held in place. The fine air bubbles adhering to the surface and the residual air under the epidermis easily separate from the rubber stopper for medicine bottles, and every corner of the vertical surface of the rubber stopper for medicine bottles to be washed is completely soaked with water. Be refined.

The pressure reduction range in this process is -300 to -1600/H
In the case of item (g), there is no boiling of the washing water, and defoaming from the entire surface of the rubber ring for medicine bottles is carried out quickly and reliably.

In the foreign matter shipping process, the washing water is heated to the upper limit temperature at which the rubber stopper for medicine bottles does not deteriorate while the rubber stopper for medicine bottles is being transported across the ocean. In addition, loose dirt on the surface of the rubber stopper for medicine bottles, such as rubber plasticizers and additives, is completely removed from the entire surface of the rubber stopper for medicine bottles, and is effectively eluted into the rice bran water.

In the rinsing process, the process of washing the bran with running water and draining the drain is repeated while the rubber stopper for medicine bottles is worshiped, so that the rubber stopper for medicine bottles, the inner wall of the body, or the inside of the bonito body such as the drainer are removed. Relatively light objects such as filth attached to objects, small pieces of rubber stoppers for medicine bottles, residual detergent, and dust are discharged out of the beard body by running water, while dust and metal particles with high specific gravity are removed by drainage. The whole body is expelled, and the inside of the bonito is almost completely dust-free, making it highly effective for rinsing.

Note that the temperature of the running water in this rinsing step is 40 to 1
0020 has a larger specific volume than when using cold water, which further improves the rinsing effect and helps shorten the process time.

In the silicone coating process, the surface of the rubber stopper for medicine bottles is siliconized by the sprayed silicone liquid while the rubber stopper for medicine bottles is being hardened, so that the entire surface of the rubber for medicine bottles is uniformly siliconized and This provides lubricity to the rubber stopper and prevents the surface from weakening as much as possible during long-term use.

In cases where silicon coating is performed in an atmosphere of 70 to 100 q○, even if homogenized silicone liquid is used, not only will the silicone and water not separate, but even the details of the rubber stopper for medicine bottles will not be separated. Siliconization is performed evenly. In the final washing process, the rubber stopper for the medicine bottle is worshiped while the washing liquid is washed with running water and the drain is drained. During the process that was carried out before the process, the inside wall of the bonito had the rubber stopper itself for medicine bottles and fine dust from the coagulant attached to it due to the particles that were scattered due to the rotation of the fly coagulator and the imitation of the rubber stopper for medicine bottles. The entire surface and the surface attachments of the sardine vessel itself are completely washed away and discharged to the outside of the fin body.

In the high-pressure steam sterilization process, the rubber stoppers for medicine bottles are entrained, but the medicine bottles are exposed to high-pressure steam at a temperature and pressure that does not cause the rubber stoppers to deteriorate, that is, the upper limit temperature and pressure at which the rubber stoppers for medicine bottles do not change. Since the rubber stopper for medicine bottles is sterilized, the entire left side of the medicine bottle rubber can be sterilized evenly and extremely efficiently.
Even if the rubber stoppers for medicine bottles become viscous at high temperatures, the rubber stoppers for medicine bottles will not become loose due to being damaged, and the temperature inside the transparent body can be easily adjusted because it is sterilized by steam. Moreover, since the rubber stopper for the medicine bottle is in a wet state, there is no friction between the rubber stoppers for the medicine bottle and each other due to imitation.

When the high-pressure steam is high-pressure steam that does not contain condensate, there is no chance of metal rust or grime in the piping contained in the condensate adhering to the rubber stopper for medicine bottles, which improves the sterilization effect accordingly. .

During the drying process, the rubber stopper for medicine bottles is being
Since the inside of the bonito body is under negative pressure and air-drying is performed using hot air, the relative humidity inside the bonito body is significantly reduced, water is easily removed from the rubber stopper for medicine bottles, and moisture under the epidermis can be easily and quickly removed from the medicine bottle. Since water is dehydrated from the rubber stopper, the rubber stopper for medicine bottles is dried evenly and efficiently from every corner, and water droplets that fall into the body of the bonito instantaneously turn into water vapor. Since it is discharged, the degree of dryness can be improved and the drying time can be shortened.

In the method of negative pressure inside the bonito shell during the drying process, which is adjusted by the difference between the amount of hot air supplied into the bonito shell and the exhaust volume, no special means is required to create a negative pressure inside the bonito shell, and both Negative pressure can be achieved only by adjusting the capacitance difference or the capacitance difference, so the configuration of the device can be made as simple as possible.

According to the method of making rubber stoppers for medicine bottles, the rubber stoppers for medicine bottles are housed in a basket attached to a rotary body that moves annularly in the vertical direction inside the can crab body, and this rotary body is rotated by a driving body. In this case, the rubber stopper for a medicine bottle is transferred within the basket due to the rotation of the rotating body, and the rubber stopper for a medicine bottle is moved due to falling within the basket when the basket moves from above to below. The rubber stoppers are thoroughly inspected and each treatment in each step is applied equally to all rubber bottle stoppers.

As described above, the present invention is extremely useful in practice as a method for washing, sterilizing, and drying rubber stoppers for medicine bottles.
