In general, dispensers are pumping devices that can pressurize a gas, liquid or gel type content stored in an airtight container which is also referred to as vacuum containers, and can dispense a constant amount thereof.

Recently, dispensers are used as containers for storing cosmetic products, perfumes, detergents, medical substances, drugs, food or the like.

A conventional dispenser is attached to an upper end of a container and includes a pump part, a button part, and a nozzle. When the button part is pushed, a shaft moves down against the elastic force of a spring, so that a filled content in a housing is discharged through a cylindrical opening or hole, a hollow part of the shaft, a connecting tube and nozzle. At this time, a ball is brought into contact with a stopper or retaining flange located at a lower end of the housing by downward pressure of a fluid in the housing.

When the button part is released, the shaft is moved upward by the elastic force of the spring, and the opening or the cylindrical hole is closed to prevent discharge of the contents, and while a vacuum is formed in the housing, so that the filled contents in the container move the ball upwards to open a valve and fill the housing.

When the button is pressed repeatedly, the above-mentioned movements are repeated and the content is downloaded.

However, such a conventional dispenser includes the ball made of a metallic material, which results in a higher production cost, and providing a valve structure that includes the ball additionally requires a post-processing, causing a problem of a production process. annoying and reduced production efficiency.

On the other hand, recent years have seen dispensers for liquids, such as nasal sprays, used to dispense or spray a constant amount of drug stored in a container.

Furthermore, Patent Document 2 describes a configuration of a fluid dispenser for spraying medication into the nose.

Furthermore, Patent Document 3 describes a configuration of a fluid dispenser that includes a constant speed pump, an inlet valve and an outlet valve.

Patent Document 4 describes a device having a fluid outlet that is provided to dispense the fluid. A pressure chamber is provided for actuation of the dispensing device to equalize the pressure through a passage opening. Air is caused to flow from the pressure chamber to the fluid container. The pressure chamber is provided with a pressure chamber housing and a piston. Two sealing lips are arranged between the piston and the pressure chamber housing. An inlet port is provided between a fluid reservoir and an interior portion of the pressure chamber.

Patent Document 5 discloses a fluid dispenser for germ-free fluid that has incorporated at least one material capable of interacting through an oligodynamically active substance. Dispenser includes a dosing pump and inlet and outlet valves. The fluid that comes into contact with at least one oligodynamically active substance is present in the region of the outlet valve, of the inlet thereto and / or the outlet thereof.

Furthermore, Patent Document 6 refers to a metering pump for a metering device for the metered dispensing of a liquid, the metering device of which can be connected to a supply container, the metering pump comprising a cylindrical pump body and a pump body. drive.

Patent Document 7 discloses a pump including a piston which, in the inoperative state, leaves a passage between the compression cavity and the opening in the second sector of the casing. A sector of the outlet channel forms a groove on the outside of the interior of two enclosures

Preferably, liner 32 comprises a cavity 321 into which elastic member 34, preferably spring 34, is insertable. This inserted spring 34 creates a pressure against the piston 21 and urges it against the outlet opening of the fluid passage 211 of the piston 21, so that the fluid passage 221 remains in a closed state until the drug dispenser is agitated. , eg pressed by a user. When the drug dispenser is shaken, a back pressure of the fluid to be discharged is created within the fluid passage 221 that is greater than the pressure generated by the elastic member 34, such as the spring 34 pushing against the piston 21, such that the piston moves away from the outlet opening of the fluid passage 221 of the piston 21, thereby opening a path that allows the fluid to be discharged to move in the direction of the outlet 30, 30 '.

The base 31 of the head is formed so that its diameter is gradually reduced towards an upper end thereof to discharge the drug into the eyes of a human body, or the like, or to spray the drug into the nasal cavity of a human body.

At the upper end of the base 31 of the head can be formed the outlet port 312 that discharges the medicine or the spray hole 312 'that sprays the medicine in the predetermined setting amount, and in a lower part of the base 31 of the Head can form a flange 313 that is pushed by the user and a vertical piece 315 that covers an upper outer side of the coupling body 11.

A distance between a lower surface of flange 313 and an upper end of coupling body 11 is a functional distance when head base 31 and valve stem 22 move up and down. That is, the upper end of the coupling body 11 serves as a stop.

On an inner side of the head base 31 a guide 314 is formed which forms the discharge passage 311 or spray passage 311 ', respectively, and the support member 316 which supports the guide 314, and on the guide 314 is arranged the liner 32 and the top of the valve stem 22.

Meanwhile, FIG. 5a is a cross-sectional view taken along line A-A 'of FIG. 3a, while Fig. 5b is a cross-sectional view taken along the line A-A 'of FIG. 3b.

As illustrated in FIG. 5a, on an inner surface of the upper end of the base 31 of the head, a droplet-forming groove 317 can be formed which reduces a discharge rate and discharge pressure and thus forms the droplet, so that the drug it is downloaded in the predetermined setting amount through the output port 312.

That is, the droplet forming means may include a contamination prevention member 33 installed between a lower surface of an upper portion of the head base 31 and an upper portion of the liner 32 and the droplet-forming groove 317.

For example, the droplet forming slot 317 may include a plurality of slots that are in communication with the outlet port 312.

In FIG. 5a, three droplet forming grooves 317 are illustrated. However, the present invention is not limited thereto, and the number, a shape, and a size of the droplet-forming grooves 317 can be changed in various ways.

The discharge passage 311 is formed to be in communication with the outlet port 312, and the outlet port 312 discharges the administered drug by upward movement of the piston 21, when the base 31 of the head is moved downward, in the drop shape.

As shown in FIG. 5b, the base 31 of the head has vortex-forming grooves 317 provided on an inner surface of its upper end to form a vortex in order to increase the speed and spray pressure for the drug to be sprayed through the spray hole 312.

More specifically, the vortex-forming means consists of the vortex-forming grooves 317 'and a contamination prevention member 33 provided between the lower surface of the upper part of the head base 31 and the upper part of the liner 32.

For example, the anti-pollution member 33 is produced in the form of a spring made of a material having a sterilization such as silver or a silver compound such as silver salts.

Furthermore, the vortexing grooves 317 'are formed in the shape of a vortex.

FIG. 5b shows three vortex-forming grooves 317 ', but the present invention is not limited to this, and the number, shape, and size of the vortex-forming grooves 317 can be changed or modified in various ways.

The spray passage 311 'is formed in communication with the spray hole 312 from which to spray the medication transferred by the piston 21 that moves upward as the base 31 of the head moves downward.

FIG. 6a is an enlarged perspective view illustrating the liner of FIG. 3a, seen at another angle. FIG. 6b is an enlarged perspective view illustrating the liner used by the drug dispenser depicted in FIG. 2b.

FIG. 6c is an enlarged perspective view illustrating the liner of FIG. 3b, seen at another angle. FIG. 6d is an enlarged perspective view of another embodiment of the liner in FIG. 6c or FIG-3b.

As illustrated in FIGS. 2a, 3a and 6a, the liner 32 is formed in the approximately cylindrical shape, and in the liner 32 the lifting space 321 can be formed where the piston 21 is inserted to move up and down, and over the space 321 of lifting, a mating groove 322 may be formed in which an upper portion of the elastic member 34, such as a. This engagement groove for elastic member 34 may be located within a cavity 328 of liner 32.

The discharge port 323 that discharges the drug delivered through the fluid passage 221 into the valve stem 22 in accordance with the upward movement of the piston 21, may be formed on one side of the liner 32 when the base 31 of the head is moved downward. , towards the outer side of the liner 32.

A transport path 324 may be formed on an outer circumferential surface of liner 32 that moves the discharged drug through discharge port 323 to the side of outlet port 312.

The upper part of the liner 32 is formed to be stepped so that its diameter is less than that of a lower part of the liner 32, and at an upper end of the liner 32 a plurality of control protrusions 325 may be formed which control the amount. of medicine discharged so that the predetermined set amount of medicine is discharged in the drop form, when the medicine is discharged one time.

Since each of the control protrusions 325 is formed to protrude from the upper end of the liner 32 toward the outlet port 312, a space that delivers the drug to the outlet port 312 can be formed between the control protrusions 325.

In addition, a plurality of engagement ribs 326 may be formed on the outer circumferential surface of liner 32 in a vertical direction.

Coupling ribs 326 serve to allow liner 32 to snap into guide 314 of head base 31, when liner 32 and head base 31 are assembled together, and thus to increase a force. coupling between liner 32 and guide 314.

If an outer diameter of liner 32 is formed to be larger than a diameter of discharge passage 311, high force is required to assemble liner 32 and head base 31, and liner 32 and guide 314 may break. or be damaged during an assembly operation.

Therefore, since the liner is formed to have the diameter corresponding to that of the discharge passage, and the plurality of coupling ribs are formed to protrude from the outer circumferential surface of the liner, the liner and the head base can be easily assembled. , and a coupling guide opening phenomenon due to a drug pressure change in a drug dispenser discharge operation can be avoided.

Fig. 6b resembles the liner as used by the drug dispenser shown in FIG. 2b. This liner is basically identically constructed, compounded with the liner shown in FIG. 6a, however, further comprises a turning path 327, which will be discussed in more detail below.

The turning path 327 is for spinning or rotating the discharged drug through the transport path 324 along the outer circumferential surface of the liner 32 and then delivers the drug to one side of the outlet port 312 that can be formed on transportation route 324 formed on top of liner 32.

Although external powders, foreign substances, bacteria, viruses, or the like are introduced from an outer side through the side of the outlet port 312, the turning path 327 serves to increase a length of a flow path into the container and also to sharply reduce your speed of movement while turning or rotating through turn path 327.

Therefore, the present invention can completely prevent foreign powders, foreign substances, bacteria and viruses from being introduced from the outer side of the drug dispenser into the drug stored in the drug dispenser.

As shown in FIGS. 2b, 3b and 6c, the liner 32 is generally formed into a cylindrical shape, and has provided therein the lifting space 321 where the piston 21 is inserted to move up and down, and the lifting space 321 has a coupling groove 322 provided in its upper part to engage the upper part of elastic member 34, such as a spring.

On one side of the liner 32 is provided the discharge port 323 through which the transferred medicament is expelled through the fluid passage 221 in the valve stem 22, out of the liner 32 by the piston 21 moving towards up as the head base 31 moves downward.

In addition, liner 32 has a transport path 324 formed on its outer circumferential surface to cause medication expelled through discharge port 323 to flow into spray port 312 '.

The top of the liner 32 is formed to gradually decrease in diameter compared to the diameter of the bottom, and the liner 32 has a control protrusion 325 formed at its upper end to adjust the amount of drug to be dispensed. spray or discharge, such that a prescribed amount of medicament is sprayed in a single spray operation or discharged in a single discharge operation, respectively.

In addition, the liner 32 has multiple engagement ribs 326 provided to protrude from the outer circumferential surface and extend in the vertical direction.

The function of the engagement ribs 326 is such that, as the liner 32 and the head base 31 are brought together, the liner 32 is pressed and fits into the guide 314 of the head base 31, resulting in a force increased engagement between liner 32 and guide 314.

If the outer diameter of liner 32 is larger than the diameter of spray passage 311 ', high force is required to assemble liner 32 and head base 31, which could cause a problem when liner 32 and / or guide 314 is / is broken or damaged during assembly.

Therefore, the liner is formed so that it has an outer diameter corresponding to the diameter of the spray passage and also has multiple coupling ribs protruding from its outer circumferential surface, so that when the liner and the head base meet , can be easily attached, and the attachment guide is prevented from widening at its opening due to a change in drug pressure at the time the drug is sprayed from the drug dispenser.

In FIG. 6d, the liner structure differs from that shown in the perspective view of FIG. 6c, the same components will be denoted by the same reference numerals and matching descriptions will be omitted.

In FIG. 6d, the transport path 324 formed on top of the liner 32 includes a turning path 327 formed to transfer the medication flowing out through the transport path 324 into the spray hole 312 'after rotating the flow around the outer circumferential surface of liner 32.

If intrusion of external dust, foreign matter, viruses, or bacteria occurs into the spray hole 312 ', the turn path 327 functions to cause the flow rate of such intrusion to sharply slow during the turn along the pipe. turning path 327 due to a longer length of the flow path to the vessel.

Accordingly, this embodiment of the present invention makes it possible to completely block any external dust, foreign matter, virus or bacteria that have been introduced into a drug dispenser from entering the medication retained in the drug dispenser.

In either embodiment, the upper and lower ends of the contamination prevention member 33 are supported by a stepped surface formed on the top of the liner 32 and an inner bottom surface of the head base 31, respectively.

The contamination prevention member 33 may form a vortex while moving the moved medicament to the top of the discharge passage 311 or the spray passage 311 ', respectively to the outlet port 312 or the spray hole 312', respectively.

The upper and lower portions of the elastic member 34, such as a spring, are inserted and installed in the engagement slot 322 of the liner 32 and the insert slot 211 of the piston 21, respectively.

The elastic member 34, such as a spring, provides the elastic force to the piston 21 that moves up and down in the lift space 321 of the liner 32.

Therefore, before the user's operation is applied to the head base 31 and when the user's operation is released, the piston 21 closes the upper end of the fluid passage 221 formed in the valve stem 22.

Meanwhile, a cover (not shown) can be attached above the base 31 of the head to prevent contamination around the outlet port 312 or the 'spray hole 312', respectively.

Next, a coupling relationship of the drug dispenser according to an embodiment will be described in detail.

First, the elastic member 34, such as a spring and the piston 21, are sequentially coupled to the interior of the liner 32, and the contamination prevention member 33 and liner 32 are coupled to the base 31 of the head, especially in the passage Discharge 311 or spray passage 311 ', respectively At this time, liner 32 is press fit into guide 314 of head base 31 by the plurality of mating ribs 326 formed on the outer circumferential surface of liner 32.

In a state where the valve stem 22 is located below the coupling body 11, the valve stem 22 is coupled to pass through the first coupling guide 141, and the elastic member 23 is installed on the outer side. of valve stem 22, and then the top of valve stem 22 is coupled to discharge port 311, or spray port 311 ', respectively.

At this time, the upper end of the elastic member 23 is supported by a lower surface of the support member 316 of the head base 31, and the lower end of the elastic member 23 is supported by the upper surface of the body connecting member 143. 11 coupling and then hooked and secured to the upper end of the second coupling guide 142.

Therefore, the elastic member 23 can be stably fixed by the second coupling guide 142, and can be elastically deformed to provide the restoring force to the head base 31, when the head base 31 is moved downward.

Next, the check valve 13 is installed in the installation space 122 of the housing 12, and the upper end of the housing 12 is coupled to a space between the connection member 143 and the second coupling guide 142 of the body 11. coupling, and then the gasket 15 is coupled thereto to securely fix the housing 12 to the coupling body 11.

An assembly operation is completed by coupling the tube to a lower end of the assembled drug dispenser as described above, and then coupling the coupling body 11 to an upper end of the container.

Next, an operation method of the drug dispenser according to an embodiment will be described in detail with reference to FIGS. 2a, 2b, 2c, 7a, 7b and 7c.

FIG. 7a is a view illustrating an operating state in which the base of the drug dispenser head of FIG. 2nd moves down.

FIG. 7b is a view illustrating an operating state in which the base of the medicament dispenser head of FIG. 2b moves down.

FIG. 7c is a view illustrating a working operating state in which the base of the head of the drug dispenser of FIG. 2c moves down.

First, as illustrated in FIG. 2a, before the user operation is applied, the piston 21 is held in its lower position by the elastic force of the elastic member 34, such as a spring, and therefore the discharge hole 323 formed in one side of the liner 32 and the upper end of the fluid passage 221 formed in the valve stem 22 is closed.

The tapered portion 222 of the valve stem 22 is in intimate contact with an inner surface of the first coupling guide 141 of the coupling body 11 and an inner surface of the housing 12, and thus the medicament is prevented from moving into the socket. upper space of the coupling body 11, or external powders, foreign substances, bacteria or viruses are prevented from getting into the housing 12.

As described above, the present invention can completely prevent contamination of the drug stored in the drug dispenser, and therefore can be used as a drug dispenser for the drug in which no preservative is added to prevent contamination and decomposition. .

Therefore, in the present invention, it is not necessary to add the preservative in a drug formulation process, and also to avoid a harmful influence on a human body due to the addition of the preservative.

As illustrated in FIG. 7a, when the user pushes the flange 313, and the head base 31 moves downward, the check valve 13 moves downward by a pressure generated while the valve stem 22 moves downward, and therefore the inlet port 121 of housing 12 is closed.

Therefore, the drug stored in the storage space 123 of the housing 12 moves along the fluid passage 221 formed in the valve stem 22 towards the discharge part 30.

As the piston 21 is moved upward by the pressure of the drug moving along the fluid passage 221 of the valve stem 22, the drug moves the discharge port 323 of the liner 32 and the transport path 324 to the upper side of the discharge passage 311, and moves along the contamination prevention member 33, the space between the liner 32 control protrusions 325, and the droplet forming groove 317, and then discharges in the form of the drop through the outlet port 312.

In Fig. 7b the same drug dispenser as shown in FIG. 7a, however, the liner 32 in this case comprises a turning path 327. This coating has already been discussed in FIG. 6b in greater detail.

In this case, since the turn path 327 is formed in the liner 32 transport path 324, the drug rotates or rotates along the outer circumferential surface of the liner 32 along the turn path 327 and thereafter delivers medication to the outlet port 312 side.

As described above, since the turning path is formed in the liner, the length of the path of movement of external dusts, foreign substances, bacteria or viruses increases, and the speed of movement is sharply reduced while rotating in the turning path, and therefore the introduction of external dust, foreign substances, bacteria or viruses into the medicine can be restricted.

The amount of drug discharged in a single downward movement of the head base 31 can be controlled by a volume of the storage space 123 formed in the housing 12 and the first and second control slots 124 and 125, a diameter of the hole 323 of discharge formed in the liner 32 and a cross-sectional area of the transport path 324, a size of the space between the control protrusions 325, and the diameter of the outlet port 312, or the like.

Another embodiment of the drug dispenser is shown in FIG. 7c. In this case, the liner 32 comprised in the drug dispenser is constructed as e.g. ex. shown in FIG 6c and therefore the drug dispenser is constructed to spray a liquid drug.

FIG. 7 is a view illustrating a working state where the base of the head of the drug dispenser in FIG. 2 has moved down.

First, before applying the user operation, the piston 21 is held in its lower position by the elastic force of the elastic member 34, such as a spring, as shown in FIG. 2c, so that the discharge port 323 provided on one side of the liner 32 and the upper end of the fluid passage 221 provided on the valve stem 22 are closed.

Thereafter, the tapered portion 222 of the valve stem 22 strongly contacts the inner surface of the first coupling guide 141 of the coupling body 11 and the inner surface of the housing 12, thereby preventing the medication from moving into the upper space of the coupling body 11 and also blocking the entry of external dust, foreign matter, bacteria and viruses into the housing 12.

In this way, the present invention allows medication held in a medication dispenser to be completely blocked from contamination, so that the dispenser can be used with preservative-free medication to prevent contamination and breakdown of the drug.

Consequently, the present invention eliminates the need to add a preservative during drug production, and therefore it is possible to reduce the problems and costs required for the drug production process and it is also possible to prevent adverse effects on human bodies. due to an addition of a preservative.

As illustrated in FIG. 7c when the user presses the flange portion 313 of the head base 31 so that the head base 31 moves downward, the check valve 13 is moved downward by the pressure applied by the valve stem 22 which is moves down, so that the inlet port 121 of housing 12 is closed.

Consequently, the drug retained in the storage space 123 of the housing 12 moves toward the spray portion 30 'along the fluid passage 221 formed in the valve stem 22.

In this way, the piston 21 is moved upward by the pressure of the medication moving along the fluid passage 221 of the valve stem 22, so that the medication moves to the top of the spray passage 311 '. through the liner 32 discharge port 323 and the transport path 324 and then moves along the contamination prevention member 33 and the vortexing grooves 317 to be sprayed from the spray port 312 'with a vortex formed in it.

Here, the amount of medicine to be sprayed is controlled by a single operation of moving the base 31 of the head downwards, for example, by adjusting the volume of the retention space 123 and the adjustment grooves 124 provided in the housing 12, the diameter 323 of the ejection orifice provided in the liner 32, the cross-section of the transport path 324 and the diameter of the spray orifice 312.

At this time, the amount of medicine discharged by a single downward movement of the head base 31 can be controlled by a volume of the storage space 123 formed in the housing 12 and the first and second control grooves 124 and 125, a diameter of discharge hole 323 formed in liner 32 and a cross-sectional area of the transport route 324, a size of the space between the control protrusions 325 and the diameter of the outlet port 312 or the spray orifice 312 ', respectively, or the like.

As described above, since the contamination preventing member is installed in the discharge or spraying passage, contamination of the drug that remained in the upper inner part of the head base can be prevented.

In addition, compared to a case where the medicine is sprayed, the diameter of the outlet port can be increased and the discharged amount of the medicine can be reduced by forming the droplet-forming groove at the upper end of the head base, when the medicine is discharged, and the medicine can be discharged in the drop form by reducing a discharge pressure and a discharge velocity.

When the drug is discharged and therefore a pressure is reduced from the top of the discharge passage 311, the piston 21 is moved downward by the elastic force of the elastic member 34, such as a spring, and the passage 221 of fluid valve stem 22 is closed.

Furthermore, when the user operation applied to the flange 313 is released, the base 31 of the head is moved upward by the restoring force of the elastic member 23, and therefore the valve stem 22 also moves upward.

At this time, a suction force is generated in the storage space 123 in the housing 12, and thus the check valve 13 moves upward to open the inlet port 121, and the drug stored in the container is enters and stores in housing 12 through tube and inlet port 121.

Meanwhile, if the amount of the drug introduced into the housing 12 exceeds the predetermined setting amount, the amount of the exceeded drug is collected into the container through the first control slots 124 and the collection port 126 of the housing 12.

Next, the user pushes the tab 313 the number of times to be discharged, and the medicine dispenser repeatedly performs the above-mentioned processes, and thereby the medicine is discharged.

By the above-mentioned processes, the liquid medicine stored in the container in the form of the drop can be discharged in the predetermined setting amount, and external powders, foreign substances, bacteria or viruses can be prevented from getting into the stored medicine. in the medicine dispenser.

Alternatively, vortexing grooves can be provided at the top end of the head base to form a vortex when the drug is sprayed, by which the amount of drug to be sprayed, the pressure can be controlled spraying and spraying speed with high precision.

Once the pressure within the top of the spray passage 311 'decreases as a result of spraying the drug, the upper end of the fluid passage 221 in the valve stem 22 is closed again by the piston 21 which it is moved downward by the elastic force of elastic member 34, such as a spring.

Furthermore, when the user operation applied to the flange 313 is released, the base 31 of the head is moved upward by the restoring force of the elastic member 23, and thus the valve stem 22 also moves upward.

At this time, a suction force is generated in the storage space 123 in the housing 12, and thus the check valve 13 moves upward to open the inlet port 121, and the drug stored in the container is enters and stores in housing 12 through tube and inlet port 121.

Meanwhile, if the amount of the drug introduced into the housing 12 exceeds the predetermined setting amount, the amount of the exceeded drug is collected into the container through the first control slots 124 and the collection port 126 of the housing 12.

Next, the user pushes the tab 313 the number of times to be discharged, and the medicine dispenser repeatedly performs the above-mentioned processes, and thereby the medicine is discharged.

By the above-mentioned processes, the liquid medicine stored in the container in the form of the drop can be discharged in the predetermined setting amount, and external powders, foreign substances, bacteria or viruses can be prevented from getting into the stored medicine. in the medicine dispenser.

Alternatively, the above process makes it possible to spray a predetermined amount of a liquid drug retained in a container and also to block the entry of external dust, foreign matter, bacteria or virus to the drug retained in a drug dispenser.

Although the present invention may be modified in various ways and have various embodiments, specific example embodiments are illustrated in the accompanying drawings and will be described in detail in the detailed description. However, the present invention is not limited to embodiments, and it should be understood that the present invention is defined by the appended claims.

That is, the embodiment is described using the medicament, but the present invention is not limited thereto.

For example, the present invention can be applied to a fluid dispenser having various forms and purposes, which discharges a liquid fluid stored in the container, such as food and medical substances, as well as medicines.

The present invention applies to the medicine dispenser capable of discharging the liquid medicine stored in the container in the predetermined amount of adjustment in the shape of the drop and preventing external powders, foreign substances or viruses from getting into the medicine stored in the dispenser. of medication.

As described above, according to the medicine dispenser of the present invention, the liquid medicine stored in the container can be discharged in the predetermined setting amount in the shape of the drop or alternatively as an aerosol, and it can be prevented from External powders, foreign substances, bacteria or viruses get into the medicine stored in the medicine dispenser.

Therefore, according to the drug dispenser of the present invention, since contamination of the drug stored in the container and the drug dispenser is completely avoided, it is possible to store and dispense the drug in which the preservative that is not added is not added. prevents contamination and decomposition

Thus, according to the drug dispenser of the present invention, it is no longer necessary to add the preservative in the drug formulation process, and it is also possible to avoid the harmful influence on the human body due to the addition of the preservative.

According to the medicine dispenser of the present invention, the contamination prevention member can be installed above the discharge passage or in the spray passage, respectively, and thus contamination of the medication remaining on top can be avoided. on the inner side of the head base.

In particular, according to the drug dispenser of the present invention, since the turning path is formed along the outer circumferential surface of the liner on top of the liner, despite the introduction of external powders, foreign substances, bacteria or viruses from the outer side through the exit port, the turning path 327 serves to increase a length of a path of movement into the container and also to dramatically reduce its speed of movement while rotating through the rotary passage, the The length of the path of movement to the container is increased, and the speed of movement is sharply reduced while rotating in the turning path, thereby restricting the introduction of external powders, foreign substances, bacteria or viruses into the container. medication stored in the medication dispenser.
