Preferably, the container 100 may be formed of a non-toxic synthetic resin, and may be formed of a transparent or translucent material or may be formed of an opaque material depending on required conditions.

In the container 100, a preservative (preservative) -free, non-preservative agent is stored, and the present invention is not limited by the kind and characteristics of the agent. For example, the medicament may be a medicament for alleviating symptoms of respiratory diseases such as asthma or a medicament for eye drops.

The pumping unit 200 is provided at an upper end of the container 100 with an air inflow passage 201 through which external air flows and a medication discharge passage 202 through which the medication is discharged. And can be pumped out to the outside.

The pumping part 200 may be provided in various structures according to required conditions and design specifications. For example, the pumping unit 200 may include a pump body 210 coupled to an upper end of the vessel 100, and a dispensing head connected to an upper portion of the pump body 210 for pumping and dispensing the agent by manual operation. and a dispensing head (220). In some cases, it is also possible to configure the pumping unit to inject the medicament automatically or semi-automatically.

The structure of the dispensing head 220 can be variously changed according to required conditions and design specifications. For example, the dispensing head 220 may include a hollow member 222, a suction valve 224, a discharge valve 226, and a push button 228.

The hollow member 222 may be formed in a substantially hollow cylindrical shape having a dispensing chamber 222a therein, and is disposed inside the pump body 210.

The suction valve 224 is provided to selectively open and close the medicine suction passage 203 connected to the lower portion of the dispensing chamber 222a and the structure and characteristics of the suction valve 224 vary according to the required conditions and design specifications . For example, the suction valve 224 operates in a kind of check valve manner according to the pressure condition of the dispensing chamber 222a, and allows the medicine of the container 100 to be introduced into the dispensing chamber 222a. A suction tube 225 is connected to the lower portion of the suction valve 224 and a lower end of the suction tube 225 is disposed adjacent to the bottom of the container 100.

The discharge valve 226 is provided to open and close the medicine discharge passage 202 connected to the upper portion of the dispensing chamber 222a and the structure and the characteristics of the discharge valve 226 can be varied according to the required conditions and design specifications can be changed. For example, the discharge valve 226 is provided to be interlocked with the push button 228, so that the discharge valve 226 can move linearly when the push button 228 is depressed and selectively open or close the medicine discharge path 202.

When the push button 228 is depressed, the discharge valve 226 moves downward to open the medicine discharge path 202. When the push button 228 is pushed, the dispensing chamber 222a is opened The filled medicine can be discharged through the medicine discharge passage 202. On the other hand, in a state in which the depressing operation of the push button 228 is released, the medicine discharge passage 202 can be blocked by the discharge valve 226. [ As described above, since the medicine discharge flow passage 202 can be shut off by the discharge valve 226 in the normal state (the state where the pushing operation of the push button is released), external air or contamination source is discharged through the medicine discharge flow passage 202 So that it can be prevented from being introduced into the fencing chamber 222a in advance.

The push button 228 is formed with an orifice 228a connected to the medicine discharge passage 202 and is pressably coupled to the upper portion of the hollow member 222. [

The push button 228 can be elastically pressed by the elastic member 229. When the manual operation of the user is completed (pressed and released), the push button 228 is pressed by the elastic force of the elastic member 229 And can be returned to the initial position.

The overcap 400 can be coupled to the upper part of the vessel 100 to cover the pumping part 200 as a whole. The overcap 400 prevents the pumping part 200 from being contaminated and damaged have. The overcap 400 may be formed of a transparent or opaque material, and the present invention is not limited or limited by the shape and structure of the overcap 400.

With this structure, the pressure in the dispensing chamber 222a caused by the pushing operation of the push button 228 causes the inflow into the dispensing chamber 222a through the suction tube 225 and the medicine suction passage 203 The medicines can be injected to the outside through the medicament discharge passage 202 and the orifice 228a.

When the push button 228 is depressed to discharge the medicine, a certain amount of air is introduced into the air inflow path 201 (step < RTI ID = 0.0 > (Not shown).

The air inflow passage 201 may be formed to be spaced apart from the medicament discharge passage 202 and may have various structures at various positions of the pumping part 200 according to required conditions and design specifications. In one example, the air inflow channel 201 may be formed in an approximately "L" shape such that it begins at the upper side of the push button 228 and penetrates the central region of the push button 228. [

The filter member 300 is provided on the air inflow channel 201 to filter air flowing through the air inflow channel 201. Hereinafter, a description will be given of an example in which a filter member 300 having a substantially bolt shape is provided at the lower end of the air inflow passage 201. In some cases, a filter member having a different structure may be provided in other portions of the air inflow passage, and the structure and mounting position of the filter member may be appropriately changed according to required conditions and design specifications.

As described above, when external air is introduced into the container, there is a possibility that the medicament may be deteriorated by the bacteria contained in the air. However, according to the present invention, bacteria and the like contained in air introduced through the air inflow channel 201 can be filtered by the filter member 300, and aseptic air can be introduced into the container 100 , It is not necessary to use a separate preservative (preservative) to prevent the deterioration of the medicine.

As the filter member 300, various filters capable of filtering air can be used. Preferably, the filter member 300 may be formed of silicon having gas permeability. Since the silicon-made filter member 300 has a mesh structure, air can pass through but the liquid can not pass through. In addition, since various bacteria or germs contained in the air passing through the filter member 300 can be filtered by the filter member 300, clean air other than various pollutants can be introduced into the container 100.

On the other hand, when a filter capable of passing both air and liquid is used as the filter member, the medicament in the dispensing chamber can be discharged to the outside through the air inflow channel. However, in the present invention, by using the filter member 300 made of silicon, air can be passed but the outflow of the medicine can be prevented.

In some cases, a secondary filter capable of sterilizing, purifying, adsorbing and neutralizing bacteria and various pollutants contained in the air together with the above-described filter member made of silicon can be used together. For example, the auxiliary filter may be formed using a photocatalyst, an activated carbon, a ceramic, a nanosilver, a HEPA filter, or the like, and the present invention is not limited or limited by the materials and characteristics of the auxiliary filter.
