Description

Gas displacement device {GAS SUBSTITUTION APPARATUS}

The present invention relates to a gas displacement device.

After filling the contents of the container (vial), such as drugs (充塡), the lid is coupled to the opening of the container and sealed. However, when the lid is coupled in a state in which oxygen remains in the headspace, which is the inner upper space of the container, the quality may be deteriorated due to oxidation of the contents filled in the container.

1 is a view showing a state in which the first gas replacement unit is disposed in the gas replacement section of the container according to an embodiment of the present invention, Figure 2 is a partial cross-sectional view taken along the line A-A of FIG. Referring to FIGS. 1 and 2 , the gas replacement device according to an embodiment of the present invention includes a first gas replacement unit 100 , and a second gas replacement unit 200 .

Here, the contents 12 contained in the container 10 may include a liquid injection. Liquid injections may generate related substances during the storage period of unsubstituted formulations in the gas filling space 14 that is the upper space of the container 10 . The amount of related substances in the unsubstituted formulation increases proportionally according to the amount of oxygen. Therefore, the amount of oxygen in the gas filling space 14 of the container 10 filled with the liquid injection needs to be managed to be at least 1% or less. And the gas filling space 14 is a space formed on the upper side of the contents 12 contained in the container 10 and refers to a space in which the gas is filled (充塡). The gas filling space 14 may be referred to as a headspace.

The first gas replacement unit 100 forms a gas replacement space (116, 126) surrounding at least the upper periphery of the container (10), and guides the flow of the replacement gas supplied to the gas replacement space (116, 126) . Here, the replacement gas may include an inert gas. The displacement gas may include nitrogen. The first gas replacement unit 100 may include a plurality of gas tunnel units that are continuously arranged along the transport direction of the vessel 10 in the gas replacement section.

Here, the linear replacement section includes a section in which the container 10 is moved after the contents 12 are filled in the container 10 until the closing of the cover. And the curve replacement section includes a section in which the cover is wired to the container (10). The gas replacement device according to an embodiment of the present invention may further include a cover sealing unit for sealing the cover by coupling the cover to the container 10 and the cover supply for supplying the cover.

The plurality of gas tunnel units may include a first gas tunnel unit 110 installed in a straight section in the gas replacement section, and a second gas tunnel unit 120 connected to one end of the first gas tunnel unit 110 . there is. The first gas tunnel unit 110 and the second gas tunnel unit 120 may be integrally formed. The first gas tunnel part 110 and the second gas tunnel part 120 may have different shapes.

The connection units 114, 124, and 204 have one end connected to a gas storage unit (not shown) for storing the replacement gas supplied to the gas filling space 14 and the gas replacement space 116 and 126, respectively, and the other end of the first gas It is connected to the replacement part (100). The connectors 114 , 124 , 204 may include hoses and connectors. Meanwhile, the connection pipe may be formed as a single conduit that is respectively coupled to the first gas tunnel unit 110 and the second gas tunnel unit 120 . However, since the connecting pipe may be formed with a plurality of conduits, it may be formed of at least one conduit without being limited to a single conduit.

Meanwhile, reference numeral 20 illustrated in FIG. 1 denotes a first wheel, and reference numeral 30 denotes a second wheel. The contents 12 are filled by the rotation of the first wheel 20 and the second wheel 30 and the container 10 to which the cover is coupled is moved to the next process along the transfer line. The above-described first wheel 20 and the second wheel 30, including the transfer line and the connection portion, etc. can be applied to the configuration used in a conventional gas replacement device, a detailed description thereof will be omitted.

Referring to FIG. 2 , the first gas tunnel unit 110 is coupled to one side of the straight first tunnel body 112 with the lower side open, and the first tunnel body 112 to prevent the flow of the displacement gas into the container ( 10) may include a first tunnel connection part 114 for guiding to the periphery. The first gas tunnel unit 110 surrounds the container 10 in a structure that minimizes an open portion in the shape of the first tunnel body 112, and can maintain an almost sealed space by reducing the gap area with the outside. there is. Accordingly, the interior of the first gas tunnel unit 110 is almost kept sealed to reduce the amount of the replacement gas supplied to the inside leaking to the outside, and it is possible to reduce the consumption of the replacement gas. If necessary, the first auxiliary tunnel body 118 may be further coupled to the first tunnel body 112 .

The gas replacement device according to an embodiment of the present invention may further include a second gas replacement unit 200 arranged in the gas replacement section to guide the flow of the replacement gas directly supplied into the gas filling space 14. The second gas replacement part 200 includes a body part 202 , an auxiliary connection part 204 , and a nozzle part 206 .

The body portion 202 is formed to have a sealed inner space, and is coupled to the first tunnel body 112 . The auxiliary connection portion 204 is coupled to one side of the body portion 202 to guide the flow of the displacement gas into the body portion 202. The nozzle unit 206 is disposed in the first tunnel body 112 having an inlet coupled to the lower side of the body 202 and having an outlet adjacent to the opening of the container 10 . The nozzle unit 206 supplies the displacement gas supplied into the body portion 202 to the gas filling space 14 through the opening of the container 10 . The nozzle inner diameter of the nozzle unit 206 may be set to 3.5mm to 25mm. Here, the nozzle inner diameter of the nozzle unit 206 may be formed to be 12 mm. When the nozzle inner diameter of the nozzle unit 206 is less than 3.5 mm, as the amount of the displacement gas supplied directly into the opening of the vessel 10 is rapidly increased, an interference phenomenon with oxygen inside the vessel 10 occurs, so that the vessel 10 ) may not be discharged to the outside. Accordingly, it may be difficult to reduce the amount of oxygen in the vessel 10 because the gas replacement efficiency is reduced. When the inner diameter of the nozzle of the nozzle unit 206 exceeds 25 mm, the pressurized atmosphere formed in the upper portion of the container 10 may be weakened. On the other hand, the limitation on the nozzle inner diameter of the nozzle unit 206 is not limited to the embodiment of the present invention, and the nozzle inner diameter of the nozzle unit 206 is designed and implemented in various forms according to the size of the opening of the container 10 . can be In this case, the nozzle inner diameter of the nozzle part 206 may be formed larger than the size of the opening of the container 10 .

The first gas tunnel unit 110 and the second gas replacement unit 200 disposed in the straight replacement section may be manufactured so that the displacement gas is directly injected from the nozzle unit 206 toward the inside of the container 10 . That is, in the straight replacement section, the interior of the first gas tunnel unit 110 may be formed as a replacement gas tunneling environment. And in the straight replacement section, the displacement gas may be directly supplied toward the inside of the container (10). Therefore, it is possible to create a replacement gas tunneling environment in which the replacement gas is filled while the container 10 moves along the transfer line. In addition, as the replacement gas is directly supplied to the gas filling space 14 inside the container 10 in a state in which the gas tunnel environment is formed, the oxygen remaining in the gas filling space 14 inside the container 10 is transferred to the container 10 . The efficiency of pushing outward can be further increased.

Fig. 3 is a partial cross-sectional view taken along line B-B of Fig. 1; Referring to FIG. 3 , the second gas tunnel unit 120 has a lower side and a part of the side open, a second tunnel body 122 having a curved shape, and a second tunnel body 122 coupled to the upper side of the second tunnel body 122 to replace it It may include a second tunnel connection 124 for guiding the flow of gas to the periphery of the vessel (10). The second gas tunnel part 120 surrounds the container 10 in a structure that minimizes the open portion in the shape of the second tunnel body 122, and can maintain an almost sealed space by reducing the gap area with the outside. there is. Therefore, the inside of the second gas tunnel part 120 is maintained in an almost sealed state to reduce the amount of replacement gas supplied to the inside leaking to the outside, it is possible to reduce the consumption of the replacement gas. The second tunnel body 122 may have a combination shape of a straight line and a curved shape. If necessary, the second auxiliary tunnel body 128 may be further coupled to the second tunnel body 122 .

The second gas tunnel unit 120 may be installed at least in the curved section of the second tunnel body 122 in the gas substitution section. The second gas tunnel unit 120 disposed in the curved replacement section may form a replacement gas tunneling environment in which the replacement gas is filled. That is, it is possible to create a gas tunnel environment to easily maintain and preserve the state in which the replacement gas is substituted in the gas filling space 14 of the container 10 while the cover is wired to the container 10 in the curve replacement section. Therefore, the oxygen remaining in the gas filling space 14 inside the container 10 is replaced with the replacement gas through the second gas tunnel part 120 continuously connected to the first gas tunnel part 110, which is a linear substitution section. And then, until the cover is wired to the container 10, it is possible to keep the environment around the container 10 as a replacement gas tunneling environment.

As described above, in the embodiment of the present invention, the replacement gas is supplied to the first gas replacement unit 100 and the second gas replacement unit 200 through the gas storage unit and the connection unit, respectively, and the first gas replacement unit 100 And by injecting or blowing the replacement gas supplied through the and second gas replacement unit 200 to push the oxygen of the gas filling space 14 inside the container 10 and to implement gas replacement in a way that fills the replacement gas can On the other hand, after the injection of the displacement gas, the cover of the container 10 is capped, and the conditions (nozzle size, pressure, replacement time) for securing the amount of oxygen in the gas filling space 14 of the container 10 to 1% or less ) can be set.

As shown in Table 3, when supplying the second replacement gas using only a general nozzle without using the first gas replacement unit 100 and the second gas replacement unit 200, the amount of oxygen in Tables 1 and 2 It was confirmed that a larger amount of oxygen remained in the vessel 10 . Therefore, in the case of supplying the second replacement gas using only a general nozzle without using the first gas replacement unit 100 and the second gas replacement unit 200, the residual in the container 10 compared to other experimental examples. It was confirmed that the improvement effect of the gas substitution rate was significantly reduced as the amount of oxygen was increased.

Through the above experimental examples, it is difficult to improve the oxygen substitution rate only with a general nozzle or individual substitution structure, and the first gas substitution part 100 and the second gas substitution part 200 are used to make the upper part of the container 10 a tunnel type. It is possible to significantly reduce the amount of oxygen remaining in the container 10 by using a double-supply structure.

On the other hand, by increasing the supply amount of the displacement gas, it is possible to maintain the inside of the gas filling space 14 at a high pressure. When the inside of the gas filling space 14 is maintained at a high pressure, it is possible to prevent the flow of outside air that may be introduced into the gas filling space 14 from the outside of the container 10 . In addition, oxygen remaining in the gas filling space 14 of the container 10 can be more easily discharged from the inside of the gas filling space 14 to the outside of the container 10 . Here, it is not necessary to limit the supply of the replacement gas to being injected at a high pressure. The supply pressure of the displacement gas can be set to a pressure condition in which the displacement flow of the gas is easily generated by the supply of the displacement gas, and the displacement gas from the outside of the container 10 can be easily filled into the interior of the container 10 .

A process for replacing oxygen filled in the gas filling space 14 of the container 10 with a set replacement gas in the gas replacement section will be described with reference to FIGS. 1 to 3 . Here, it is assumed that the container 10 has a gas filling space 14 on the upper side containing the contents 12 through the opening and is transported along the transport direction by a transport means such as a conveyor belt in the transport line. And it is assumed that the replacement gas supplied from the gas storage unit is supplied to the first gas replacement unit 100 and the second gas replacement unit 200 through the connection unit, respectively.

First, when the container 10 is positioned in the gas substitution section, the upper periphery of the container 10 under the influence of the substitution gas filled inside the first gas substitution part 100 and the second gas substitution part 200 is a substitution gas surrounded by Inside the first gas replacement unit 100 and the second gas replacement unit 200, each replacement gas supplied from the gas storage unit is supplied through the connection unit, and the replacement gas is filled. The supply of the displacement gas should be maintained at least at a high pressure. Accordingly, it is possible to prevent the external air remaining outside the container 10 from flowing into the gas filling space 14 of the container 10 . In addition, as the supply of the displacement gas is maintained at a high pressure, the oxygen remaining in the gas filling space 14 of the container 10 may be discharged to the outside of the container 10 .

For reference, as the first gas replacement unit 100 is formed of a plurality of gas tunnel units, the first gas tunnel unit 110 and the second gas tunnel unit, it is possible to more easily fill the replacement gas of the container 10 . When the container 10 moves through the first gas tunnel part 110 and the second gas tunnel part 120 , it is affected by the gas filling space 14 and the gas substitution space 116 and 126 surrounded by the displacement gas. . That is, oxygen is discharged from the gas filling space 14 of the container 10 and the replacement gas is replaced and filled in its place. In particular, as the first gas tunnel unit 110 and the second gas tunnel unit 120 are formed such that a replacement gas is supplied to the upper region including the opening of the vessel 10 , the vessel 10 is the first gas tunnel unit. When passing through 110 and the second gas tunnel unit 120 , oxygen in the gas filling space 14 is disturbed to promote gas replacement. In addition, the replacement gas is supplied to the inside of the first gas tunnel part 110 and the second gas tunnel part 120 , and the external air remaining outside the container 10 is moved to the gas filling space 14 of the container 10 . It can be easily prevented from entering.

The first gas tunnel part 110 and the second gas tunnel part 120 surround the container 10 in a structure that minimizes the opening portion in each tunnel shape, and reduces the area of the gap with the outside to be almost sealed. space can be maintained. Accordingly, the interior of the first gas tunnel unit 110 and the second gas tunnel unit 120 is almost kept sealed, so that air containing oxygen is not introduced from the outside.

Although preferred embodiments of the present invention have been described above, the present invention is not limited thereto, and it is possible to carry out various modifications within the scope of the claims, the detailed description of the invention, and the accompanying drawings, and this is also It goes without saying that they fall within the scope of the present invention.
