Description

Double-sealed drug filling container

[0001] The present invention relates to a drug filling container with a double sealing structure, and more specifically, to a drug filling container with a double sealing structure that can maintain airtightness while having a luxurious appearance by simultaneously applying a press fit and a fusion method.

[0002] Ampoules or vials are containers that can be formed from glass or plastic materials. In the case of ampoules formed from glass, mass production is difficult because they undergo a melting and sealing process to fill the container with drugs and then melt and seal the opening of the container. Additionally, there is the inconvenience of having to cut them according to a prescribed method because a large amount of glass fragments may be generated when cutting the head of the ampoule during use.

[0003] To resolve this inconvenience, ampoules or vials made of plastic do not cause the problem of glass fragments, but containers made of plastic have the problem of lower productivity in the drug filling and sealing process compared to ampoules made of glass.

[0004] In addition, there is a need for a container capable of stable storage so that the composition of the contents does not change after sealing an ampoule or vial formed of plastic material, and there is a need to enable mass production of an ampoule or vial formed of plastic material.

[0005] Registered Patent Publication No. 10-2083549 relates to a container that holds and seals a drug, wherein the filling time is reduced by filling the drug into the container through a container cap portion equipped with a filling groove, and the head portion is provided to prevent the head portion from separating from the container body portion during storage and to allow the head portion to be easily separated from the container body portion during use, and the seal is achieved by ensuring that fusion occurs after the container cap portion and the container body portion are pressed together. However, in order to enable stable storage without changes in the composition of the contents and to enable mass production after performing the drug filling and sealing process in a container formed of plastic material, a more specific configuration is required.

[0006] US Patent Publication US 8,640,899 B2 relates to a vial containing a predetermined amount of drug, wherein a hole is provided on the side of the stopper portion to fill the drug, and after filling, the side of the stopper portion is pressed into the body portion and pushed into the seating portion, and a cut portion is formed between the tip of the stopper portion and the seating portion, but the hole formed on the side of the stopper portion must be smaller than a predetermined size so that the drug does not flow out again during drug filling, so there is a problem that the size of the hole cannot be made larger to reduce the drug filling time, and additionally, the cut portion formed between the tip of the stopper portion and the seating portion has a problem that it cannot be easily opened by hand as the strength is increased so that it is not damaged by a force acting in the longitudinal direction of the vial. Furthermore, lowering the strength of the cut section to allow for easy manual opening poses a risk of breakage, requiring caution when press-fitting the cap and body after drug filling. There is also a significant risk of damage during the packaging and transportation process. Therefore, a more specific configuration is required to enable stable storage without changes in the composition of the contents after drug filling and sealing in plastic containers, as well as to facilitate mass production.

[0007] Published Patent Application No. 10-2004-0005112 relates to a manufacturing apparatus and method for plastic ampoules. In this method, contents are filled through a liquid injection port after removing a primary bonding part and heat fusion is performed. However, since the primary bonding part must be removed to fill the contents and sealing is impossible before heat fusion is performed after filling the contents, there are problems such as the fact that filling the contents takes a long time and it is difficult to prevent contamination before heat fusion is performed, which can lead to low productivity. Furthermore, a more specific configuration is required to enable stable storage without changes in the composition of the contents and to enable mass production after performing the drug filling and sealing process in a container formed of plastic material.

[0008] Published Patent Application No. 10-2007-0044658 relates to an ampoule and a method for manufacturing the same. In this method, a separate incision line formed in advance for injection is cut to open the injection port, an injection solution is injected, and the upper end of the injection port is sealed by a mold. Since the incision line must be cut to open the injection port in order to fill the contents, and a mold is required to seal the injection port after filling the contents, there is a problem in that it takes a long time to fill the contents and seal the injection port, and productivity may be low.

[0009] Registered Patent Publication No. 10-0381404 relates to a device for molding plastic ampoules, filling contents, and sealing containers, comprising: an extruder located at the top of the device that extrudes resin to produce a semi-molten cylindrical resin; a main mold having a shape of a container imprinted thereon and a plurality of vacuum pins perforated therein; a sealing mold located at the top of the main mold and having vacuum pins perforated therein; and an injection tube located at the top of the sealing mold that sequentially injects air and contents, but has the problem that it is difficult to inject contents and seal ampoules in large quantities.

[0010] Registered Patent Publication No. 10-1295948 relates to a tool horn that receives vibration energy from an ultrasonic welding machine and transmits energy by directly contacting the weld. The tool horn is formed in multiple stages, and as it approaches the end, the diameter decreases at regular intervals. The multi-stage portion is formed in a rounded shape, and a hole through which a coil passes is formed to penetrate from the side of the second stage of the tool horn to the end. However, there is a problem in that it is difficult to seal the weld in large quantities.

[0011] The present invention aims to provide a drug filling container with a double sealing structure that can maintain airtightness while having a luxurious appearance by simultaneously applying a press fit method and a fusion method.

[0017] In order to solve the above problem, the present invention includes the following configuration.

[0018] The present invention relates to a drug filling container having a double sealing structure, comprising: a container stopper portion having a plate-shaped cover portion and a raised portion formed at a predetermined height from the cover portion, wherein at least one filling groove is formed on the outer surface of the raised portion for injecting a drug; and a container body portion having an opening into which the raised portion is inserted and which is sealed by contacting the cover portion; wherein the container body portion comprises: a fusion ridge formed protruding in the longitudinal direction at the end of the opening of the container body portion; and a stopper formed protruding in the radial center direction at the end of the opening of the container body portion.

[0019] The cover portion of the present invention is characterized by being formed larger than the inner diameter of the container body portion so that when the raised portion is inserted into the opening of the container body portion, it comes into contact with the outer end of the opening of the container body portion and seals the opening of the container body portion.

[0045] The overall structure and operation according to a preferred embodiment of the present invention will be described below. These embodiments are exemplary and do not limit the structure and operation of the present invention. Other structures and operations not explicitly shown in the embodiments may also be considered as part of the technical concept of the present invention if they are easily understood by a person skilled in the art through the embodiments described below.

[0046] Generally, ampoules or vials are containers that can be formed from glass or plastic materials. In the case of ampoules formed from glass, there are limitations in increasing productivity because the opening of the container is melted and sealed after filling the container with drugs. When the container body or the container cap is formed from plastic, measures are needed to increase productivity in the drug filling and sealing process compared to ampoules formed from glass.

[0047] Figure 1 conceptually illustrates the process of filling a drug using the vacuum principle into a double-sealed drug filling container according to the present invention.

[0048] Referring to FIG. 1, the drug filling device of the drug filling container of the present invention includes a vessel (100), a vessel cover (110), a vacuum valve (200), a gas injection valve (210), a drug supply valve (220), and a water level control switch (300).

[0049] The above vessel (100) contains a drug (10) inside, and the vessel cover (110) seals the inside of the vessel (100) when the filling groove (421) of the drug filling container (400) is submerged in the drug (10).

[0050] Since the filling groove (421) of the drug filling container (400) is submerged in the drug (10), the pressure (P1) inside the drug filling container (400) may be slightly higher than the pressure (P2) inside the vessel (100) and the pressure (P3) outside the vessel (100), but this is negligible.

[0051] Ultimately, the pressure (P1) inside the drug filling container (400), the pressure (P2) inside the vessel (100), and the pressure (P3) outside the vessel (100) can all be considered to be nearly identical to each other.

[0052] The vacuum valve (200) controls the vacuum pressure inside the vessel (100) by discharging air from inside the vessel (100) to the outside in order to form a vacuum inside the vessel (100). The vacuum pressure is closely related to the amount of drug to be filled in the drug filling container (400), and if the vacuum pressure is high, a high weight can be filled, and if the vacuum pressure is low, a low weight can be filled.

[0053] The vacuum valve (200) discharges air from inside the vessel (100) to the outside in order to form a vacuum inside the vessel (100), and makes the internal pressure of the drug filling container (400) equal to the pressure inside the vessel (100).

[0054] When the vacuum pressure required by the vacuum valve (200) is reached, the vacuum valve (200) is closed and the gas injection valve (210) is opened and gas is injected into the vessel (100). As a result, the vacuum level inside the vessel (100) is released, and a pressure difference is created between the pressure (P2) inside the vessel (100) and the pressure (P1) inside the drug filling container (400), causing the drug (10) to be drawn into the drug filling container (400) and drug filling is performed.

[0055] The drug filling operation based on this vacuum principle proceeds until the pressure (P2) inside the vessel (100) and the pressure (P1) inside the drug filling container (400) become equal.

[0056] As the above drug (10) is filled into the drug filling container (400), the level of the drug (10) contained inside the vessel (100) decreases; therefore, the level control switch (300) detects the level of the drug (10) contained inside the vessel (100) and operates the drug supply valve (220) to supply the filling drug inside the vessel (100). That is, the drug supply valve (220) is operated to continuously and consistently maintain the level of the drug (10) at the height set by the level control switch (300), thereby supplying the filling drug.

[0057] The above drug filling container (400) includes a container body part (410) and a container stopper part (420), and the container stopper part (420) has a plate-shaped cover part (422) and a raised part (423) formed at a predetermined height from the cover part (422), and at least one filling groove (421) is formed on the outer surface of the raised part (423) to inject a drug.

[0058] The above container body (410) has an opening into which the above-mentioned protrusion (423) is inserted and which is sealed by contacting the above-mentioned cover (422).

[0059] The raised portion (423) of the container stopper portion (420) is provided with a first seating portion (424), a second seating portion (425), and a third seating portion (426) that are inserted into the opening of the container body portion (410), and is formed so that the outer diameter increases in the order of the first seating portion (424), the second seating portion (425), and the third seating portion (426).

[0060] The above-mentioned filling groove (421) is formed across the first seating portion (424) and the second seating portion (425), and a locking projection (412) formed at the opening end of the container body portion (410) is fitted into a locking groove (427) formed between the first seating portion (424) and the second seating portion (425), and the filling groove (421) is exposed and the filling groove (421) is submerged in the drug (10), so that the vacuum valve (200) forms a vacuum inside the vessel (100), thereby discharging air from inside the vessel (100) as well as inside the drug filling container (400) to the outside.

[0061] In this state, the gas injection valve (210) then injects gas into the vessel (100) so that the drug (10) is filled into the drug filling container (400).

[0062] It is preferable to maintain the same position of the drug filling container (400) inside the vessel (100) while the vacuum valve (200) discharges air inside the vessel (100) to the outside to form a vacuum inside the vessel (100), and the gas injection valve (210) injects gas into the vessel (100) so that the drug (10) is filled into the drug filling container (400).

[0063] The drug filling operation proceeds until the pressure (P2) inside the vessel (100) and the pressure (P1) inside the drug filling container (400) become equal to each other, thereby completing one filling operation. Since the time required for this filling operation is determined by the time the drug (10) moves into the drug filling container (400) through the filling groove (421), the present invention can maximize production by forming a plurality of filling grooves (421) to shorten the time required for the filling operation.

[0064] In addition, if the size of the filling groove (421) is too large, the drug (10) filled into the drug filling container (400) may flow out, so the size of the filling groove (421) can be maintained appropriately and the number of them can be increased to shorten the time required for the filling operation.

[0065] FIG. 2 shows an exploded perspective view of a drug filling container with a double sealing structure according to the present invention.

[0066] Referring to FIG. 2, the drug filling container (400) of the present invention comprises a container body portion (410) and a container stopper portion (420), and the container stopper portion (42) comprises a plate-shaped cover portion (422) and a raised portion (423) formed at a predetermined height from the cover portion (422), and at least one filling groove (421) is formed on the outer surface of the raised portion (423) to inject a drug.

[0067] The above container body (410) has an opening into which the above-mentioned protrusion (423) is inserted and which is sealed by contacting the above-mentioned cover (422).

[0068] The raised portion (423) of the container stopper portion (420) is provided with a first seating portion (424), a second seating portion (425), and a third seating portion (426) that are inserted into the opening of the container body portion (410), and is formed so that the outer diameter increases in the order of the first seating portion (424), the second seating portion (425), and the third seating portion (426).

[0069] The above-mentioned filling groove (421) is formed across the first seating portion (424) and the second seating portion (425), and a locking projection (412) formed at the opening end of the container body portion (410) is fitted into a locking groove (427) formed between the first seating portion (424) and the second seating portion (425), and the filling groove (421) is exposed and the filling groove (421) is submerged in the drug (10), so that the vacuum valve (200) forms a vacuum inside the vessel (100), thereby discharging air from inside the vessel (100) as well as inside the drug filling container (400) to the outside.

[0070] In this state, the gas injection valve (210) then injects gas into the vessel (100) so that the drug (10) is filled into the drug filling container (400).

[0071] The container head portion (430), formed on the opposite side from the opening end of the container body portion (410), allows the user to make a smooth cut at the cutting portion (431) using the principle of a lever, and the user can easily drink the medicine through the drinking portion (432).

[0072] A flat surface is further formed on the head portion (430) of the container to allow the user's finger to be supported more easily, and the drinking portion (432) is formed to have a smaller diameter than the body portion (410) of the container, so that the diameter of the head portion (430) of the container can also be formed smaller, allowing the user to drink the medicine more easily and enabling smoother cutting.

[0073] FIGS. 3(a) and FIGS. 3(b) illustrate the connection between the container body and the container stopper when filling a drug into the double-sealed drug filling container of the present invention.

[0074] Referring to FIG. 3(a) and FIG. 3(b), when filling a drug into the double-sealed drug filling container of the present invention, the connection between the container body part (410) and the container stopper part (420) is shown in a transparent perspective view and a transparent cross-sectional view.

[0075] The above container stopper (420) is provided with a plate-shaped cover portion (422) and a raised portion (423) formed at a predetermined height from the cover portion (422), and at least one filling groove (421) is formed on the outer surface of the raised portion (423) to inject a drug.

[0076] The raised portion (423) of the container stopper portion (420) is provided with a first seating portion (424), a second seating portion (425), and a third seating portion (426) that are inserted into the opening of the container body portion (410), and is formed so that the outer diameter increases in the order of the first seating portion (424), the second seating portion (425), and the third seating portion (426).

[0077] In order to fill the drug while the filling groove (421) is locked in the drug (10) inside the vessel (100), the locking projection (412) formed at the end of the opening of the container body (410) is fitted into the locking groove (427) formed between the first seating portion (424) and the second seating portion (425), and the filling groove (421) formed on the outer surface of the raised portion (423) is exposed so that the filling groove (421) is locked in the drug (10) inside the vessel (100).

[0078] With the locking projection (412) formed at the opening end of the container body (410) inserted into the locking groove (427) formed between the first seating portion (424) and the second seating portion (425), a vacuum is formed inside the vessel (100) to expel air from inside the vessel (100) as well as inside the drug filling container (400) to the outside, and then gas is injected into the vessel (100) to fill the drug (10) into the drug filling container (400), thereby maintaining stability.

[0079] FIG. 4 illustrates the process of filling drugs collectively and continuously into a plurality of drug filling containers according to the present invention.

[0080] Referring to FIG. 4, the drug filling device of the present invention utilizes a tray (510) to fill drugs into a plurality of drug filling containers in a batch and continuously.

[0081] The above tray (510) is provided with a plurality of container holes (511) and a plurality of hot water passage sections (512), and a drug filling container (400) is mounted in each of the plurality of container holes (511) to align the plurality of drug filling containers (400) on the tray (510).

[0082] The drug filling operation for the plurality of drug filling containers (400) can be processed in tray (510) units, and the plurality of drug filling containers (400) aligned on the tray (510) are fixed to the vessel guide (710) with the container cap portion (420) positioned at the top and the container head portion (430) positioned at the bottom, and are moved to the top of the vessel (100) for the drug filling operation.

[0083] As an exemplary embodiment of the present invention, a plurality of drug filling containers (400) aligned on two trays (510) can be simultaneously accommodated inside the vessel (100). First, the two trays (510) are fixed to the vessel guide (710) and moved to the upper part of the vessel (100). Then, the rising / falling / reversing device (700) reverses the vessel guide (710) so that the plurality of drug filling containers (400) are positioned such that the container head portion (430) is located at the top and the container stopper portion (420) is located at the bottom, and then lowers.

[0084] A plurality of drug filling containers (400) aligned on two trays (510) lowered by the above-mentioned rising / falling / reversing device (700) are simultaneously submerged in the drug (10) inside the vessel (100), and the drug filling operation proceeds with the filling grooves (421) of the plurality of drug filling containers (400) aligned on the two trays (510) submerged in the drug (10) inside the vessel (100).

[0085] In order to fill the drug (10), a stopper (412) formed at the opening end of the container body (410) is fitted into a stopper groove (427) formed between the first seating portion (424) and the second seating portion (425) of the raised portion (423) of the container stopper (420), and the filling groove (421) formed on the outer surface of the raised portion (423) is exposed so that the filling groove (421) is submerged in the drug (10) inside the vessel (100).

[0086] While the catch (412) formed at the opening end of the container body (410) is fitted into the catch groove (427) formed between the first seating portion (424) and the second seating portion (425), a vacuum is formed inside the vessel (100) to expel air from inside the vessel (100) as well as inside the drug filling container (400) to the outside, and then gas is injected into the vessel (100) so that the drug (10) is filled into the drug filling container (400), the two trays (510) maintain the same position inside the vessel (100).

[0087] If the tray (510), etc. inside the vessel (100) moves during the process of forming a vacuum inside the vessel (100) and injecting drugs, it may affect the vacuum state inside the vessel (100) and reduce production efficiency.

[0088] FIG. 5 illustrates a plurality of drug filling containers of the present invention arranged in a tray for filling with drugs.

[0090] At this time, the catch (412) formed at the end of the opening of the container body (410) is fitted into the catch groove (427) formed between the first seating portion (424) and the second seating portion (425), and the filling groove (421) formed on the outer surface of the raised portion (423) is exposed so that the filling groove (421) can be submerged in the drug (10) inside the vessel (100).

[0091] FIG. 6 illustrates a tray and a protective frame, which are auxiliary devices for collectively and continuously filling drugs into a plurality of drug filling containers according to the present invention and sealing them.

[0092] Referring to FIG. 6, the invention includes a tray (510) and a protective frame (520) as auxiliary devices for collectively and continuously filling drugs into a plurality of drug filling containers (400) and sealing them.

[0093] The above tray (510) is provided with a plurality of container holes (511) and a plurality of hot water passage parts (512) to enable the filling of drugs and the fusion of drug filling containers to be performed collectively and continuously.

[0094] A plurality of drug filling containers (400) are mounted and aligned in each of the plurality of container holes (511), and a plurality of hot water passage sections (512) are formed between each of the plurality of container holes (511).

[0095] The above protective frame (520) forms an opening at the top and a protrusion (521) on the inner side of the side to prevent deformation in a high-temperature environment, and the tray (510) is mounted and supported so that a plurality of drug filling containers (400) are mounted and aligned, thereby protecting the container head portion (430) of the plurality of drug filling containers (400) from being damaged.

[0096] The plurality of hot water passage sections (512) are configured such that when a plurality of drug filling containers (400) are mounted and aligned in each of the plurality of container holes (511), hot water passes through to ensure that heat is applied evenly throughout, and the protective frame (520) has an outlet (522) formed at the bottom so that when hot water is sterilized, it does not stagnate within the protective frame (520) but is discharged smoothly.

[0097] Ultimately, even when multiple drug filling containers (400) are mounted and aligned in each of the multiple container holes (511), homogeneous heat penetration is possible for all drug filling containers (400), so that post-sterilization can be achieved.

[0098] For example, 36 container holes (511) are formed in the tray (510), so that 36 drug filling containers (400) are mounted and aligned in one tray (510) to fill and seal drugs collectively and continuously.

[0099] In addition, a space is secured below the lower surface of the above-mentioned protective frame (520) to protect the container cap portion of the drug filling container mounted on another protective frame and tray, so that even if multiple drug filling containers (400) are mounted and aligned and multiple protective frames and trays are stacked in layers with the above-mentioned tray (510) mounted, the multiple drug filling containers (400) can be protected.

[0100] FIG. 7 illustrates a plurality of drug filling containers of the present invention arranged in a tray and mounted on a protective frame.

[0101] Referring to FIG. 7, a tray (510) with a plurality of drug filling containers (400) mounted and aligned is mounted and supported on a protective frame (520), and in this state, post-sterilization is performed and storage and transport are possible.

[0102] During post-sterilization, hot water passes through multiple hot water passages (512) formed between each of the multiple container holes (511), allowing heat to be applied evenly throughout, and the hot water is discharged without stagnation through the discharge port (522) formed at the bottom of the protective frame (520).

[0103] In addition, a space is secured below the discharge port (522) of the protective frame (520), that is, below the lower surface of the protective frame (520), to protect the container cap portion of the drug filling container mounted on another protective frame and tray, so that a plurality of drug filling containers (400) can be mounted and aligned, and a plurality of protective frames and trays can be stacked in layers with the tray (510) mounted.

[0104] FIG. 8 shows an exploded cross-sectional view of a double-sealed drug filling container according to the present invention.

[0105] Referring to FIG. 8, the drug filling container (400) of the present invention comprises a container body portion (410) and a container stopper portion (420). The container stopper portion (420) is provided with a plate-shaped cover portion (422) and a raised portion (423) formed at a predetermined height from the cover portion (422). The structure is such that the raised portion (423) is inserted into the opening of the container body portion (410) and comes into contact with the cover portion (422) to seal it.

[0106] It is preferable that the raised portion (423) of the container stopper portion (420) forms a sloped structure from the end to the cover portion (422) and forms a steeper slope portion (427) at the part where the raised portion (423) and the cover portion (422) meet.

[0107] The raised portion (423) is formed such that its outer surface has an incline so that the pressure applied to the inner wall of the container body portion (410) increases as it is inserted into the opening of the container body portion (410).

[0108] The slope of the outer surface of the raised portion (423) is formed such that it becomes maximum at the point where the outer surface of the raised portion (423) meets the cover portion (422), that is, the slope of the outer surface of the raised portion (423) is formed such that it becomes maximum at the point where the outer diameter of the raised portion (423) meets the cover portion (422).

[0109] The raised portion (423) of the container stopper portion (420) can be inserted into the opening of the container body portion (410) and compressed, and then completely sealed through a fusion process, but it is difficult to fuse and seal multiple drug filling containers (400) simultaneously with a general fusion process.

[0110] To solve these difficulties, the present invention forms a fusion ridge (411) protruding in the longitudinal direction at the end of the opening of the container body (410) and a stopper (412) protruding in the radial center direction at the end of the opening of the container body (410).

[0111] In order to completely seal the container body (410) and the container stopper (420), the welding process may use an ultrasonic welding method, but before that, the container body (410) and the container stopper (420) are joined by a compression method of a press fit.

[0112] The connection between the container body (410) and the container stopper (420) proceeds in stages. First, a first-stage fitting method connection for filling the drug is performed, that is, a connection is made in which a stopper (412) formed at the end of the opening of the container body (410) is fitted into a stopper groove (427) formed between the first seating portion (424) and the second seating portion (425). Afterward, a second-stage press-fit method connection is performed to prevent the drug filled inside the container body (410) from flowing out. Finally, a third-stage press-fit method connection and an ultrasonic welding method are performed together to completely seal the container.

[0113] At this time, the stopper (412) performs an intermediate stopper function in the first fitting method of joining the container body part (410) and the container stopper part (420) and the second press fitting method of joining, and when the third press fitting method of joining and the ultrasonic welding method are performed together, it applies pressure to the side of the container body part (410) and the container stopper part (420) and the third seating part (426), and prevents and withstands the opening end of the container body part (410) from being damaged when expansion stress occurs from inside to outside the container body part (410), thereby allowing smooth ultrasonic welding to be performed.

[0114] In addition, the above fusion plate (411) can be bonded by fusion while in close contact with the cover portion (422) of the container stopper portion (420), thereby maintaining double airtightness.

[0115] Ultimately, the container body (410) and the container stopper (420) are joined by a first-stage fitting method using an inclined structure and a stopper (412), and sealed by pressure using a second and third-stage forced fitting method, and the fusion ridge (411) of the container body (410) and the cover (422) of the container stopper (420) are fused to achieve double sealing.

[0116] FIG. 9 illustrates a combined cross-sectional view of a drug filling container with a double sealing structure according to the present invention.

[0117] Referring to FIG. 9, a transparent cross-sectional view is shown of the container body (410) and container stopper (420) of a drug filling container being completely sealed using a press-fit method and an ultrasonic welding method.

[0118] The locking projection (412) formed on the inner side of the opening end of the container body part (410) is shown to be fused while performing lateral pressure at the point (450) where the outer side of the container stopper part (420) and the cover part (422) meet.

[0119] In addition, the fusion ridge (411) formed by protruding in the longitudinal direction at the opening end of the container body part (410) is bonded by fusion at the point (440) that is in close contact with the cover part (422) of the container stopper part (420), showing that it maintains airtightness.

[0120] FIG. 10 shows a perspective view of a fusion bond for fusing a drug filling container with a double seal structure according to the present invention.

[0121] Referring to FIG. 10, a plurality of fusion rings (610) are formed at the lower part of the fusion ring (600) for fusing the double-sealed drug filling container of the present invention.

[0122] The above fusion horn (600) effectively emits mechanical vibrations transmitted from a vibrator that converts electrical vibrations into mechanical vibrations and a booster that amplifies the mechanical vibrations of the vibrator.

[0123] The above fusion ring (610) is formed at the bottom of the above fusion ring (600) to effectively emit mechanical vibrations of the booster and transmit them to the drug filling container, thereby pressing and fusing the container body part (410) and the container stopper part (420).

[0124] Generally, a single fusion ring is formed in a single fusion ring to perform the fusion process, because minute shape differences between drug filling containers molded with the same mold affect the fusion process, making it difficult to perform the fusion process on multiple drug filling containers simultaneously by forming multiple fusion rings in a single fusion ring.

[0125] The fusion ring (600) of the present invention forms a plurality of fusion rings (610) in a single fusion ring (600) so that a fusion process can be performed simultaneously on a plurality of drug filling containers (400), while ensuring stable fusion. The main reason for this is the structure of the container body part (410) and the container stopper part (420) described above in relation to FIG. 9.

[0126] In particular, in one embodiment of the present invention, nine fusion rings (610) are formed in one fusion ring (600) so that the fusion process is performed simultaneously on nine drug filling containers (400) and they are stably sealed.

[0127] FIG. 11(a) shows a side view of a fusion bond for fusing a drug filling container with a double seal structure according to the present invention, and FIG. 11(b) shows a bottom plan view of a fusion bond for fusing a drug filling container with a double seal structure according to the present invention.

[0128] Referring to FIG. 11(a) and FIG. 11(b), the fusion ring (600) for fusing the double-sealed drug filling container of the present invention forms nine fusion rings (610) on its lower side so that the fusion process can be performed simultaneously on nine drug filling containers (400).

[0129] FIG. 12 illustrates the connection relationship between the container stopper and the container body when the double-sealed drug filling container of the present invention is sealed by welding.

[0130] Referring to FIG. 12, the fusion ring (600) for fusing the double-sealed drug filling container of the present invention forms nine fusion rings (610) on its lower side so that the fusion process is performed simultaneously on nine drug filling containers (400). Since FIG. 13 is a side view, only three of the nine fusion rings (610) and nine drug filling containers (400) are shown.

[0131] After the drug is filled in the first fitting-type connection state between the container body part (410) and the container stopper part (420) of the drug filling container (400), washing and drying are performed in the second press-fit connection state between the container body part (410) and the container stopper part (420).

[0132] Next, the third press-fit method of joining the container body part (410) and the container stopper part (420) and the ultrasonic welding method are carried out together by the above-mentioned welding method (600) so that they can be completely sealed.

[0133] With respect to FIGS. 3, 8, and 9, the stopper (412) performs an intermediate stopper function in the first fitting method of joining the container body part (410) and the container stopper part (420) and in the second press fitting method of joining, and performs pressure on the side of the container body part (410) and the container stopper part (420) when the third press fitting method of joining and the ultrasonic welding method are performed together, and prevents and withstands the opening end of the container body part (410) from being damaged when expansion stress occurs from inside to outside the container body part (410), thereby allowing smooth ultrasonic welding to be performed.

[0134] In addition, the above fusion plate (411) can be bonded by fusion while in close contact with the cover portion (422) of the container stopper portion (420), thereby maintaining double airtightness.

[0135] In addition, the container body part (410) and the container stopper part (420) can be sealed by a forced-fit type of pressure using an inclined structure and the stopper (412), and the fusion ridge (411) of the container body part (410) and the cover part (422) of the container stopper part (420) are fused to create a double seal.

[0136] FIGS. 13 and 14 illustrate the operation of a fusion bond for fusing a drug filling container with a double seal structure according to the present invention.

[0137] Referring to FIGS. 13 and 14, the third press-fit method of joining the container body part (410) and the container stopper part (420) and the ultrasonic welding method are carried out together by the welding horn (600) and the lower jig (800) to be seen in more detail as they are completely sealed.

[0138] After the drug is filled in the first-stage interlocking state of the container body (410) and the container stopper (420) of the drug filling container (400), and after washing and drying are performed in the second-stage interlocking state of the container body (410) and the container stopper (420), the third-stage interlocking state of the container body (410) and the container stopper (420) and the ultrasonic welding method are performed together by the fusion bond (600) to completely seal the container.

[0139] As an example, nine welding rings (610) are formed on the welding ring (600), and the welding rings (610) are made such that their diameters match the container stopper portion (420), so that when the welding ring (600) is lowered once, ultrasonic vibration energy is simultaneously transmitted to the maximum extent to nine drug filling containers (400) to achieve welding.

[0140] In order to fuse nine drug-filled containers (400) simultaneously, nine drug-filled containers (400) are arranged on an auxiliary tray (510), and the process is moved in tray units.

[0141] A tray (510) in which nine drug filling containers (400) are aligned is placed under the fusion ring (600) so that the center of the fusion ring (610) and the center of the drug filling containers (400) coincide with each other, and a lower jig (800) is raised by a jig drive unit (810) to fix and support the nine drug filling containers (400), and the fusion ring (600) is lowered to come into close contact with the nine drug filling containers (400).

[0142] At the bottom, the lower jig (800) fixes and supports the nine drug filling containers (400), and at the top, the fusion ring (600) is in close contact with the nine drug filling containers (400) and transmits ultrasonic vibration energy to perform fusion.

[0143] In addition, the above fusion horn (600) transmits ultrasonic vibration energy while applying downward pressure to nine drug filling containers (400), and the lower jig (800) responds to the downward pressure by applying a jig driving unit (810), which is a hydraulic system.
