Description

[Technical Field]

[0001] This invention relates to a medicine cup structure, specifically a medicine cup structure for opening a blow-fill-seal (BFS) container filled with liquid medicine. This medicine cup structure allows for simultaneous opening of the BFS container during assembly, providing a convenient opening mechanism for users with trembling hands without the need for additional alignment. This medicine cup structure can be used with BFS containers of varying sizes and capacities without limitation, and is particularly suitable for very small BFS containers, such as 1cc or less, effectively preventing liquid medicine from spilling out when the medicine cup structure is tilted. Furthermore, after use, the BFS container can be poured out simply by reassembling the medicine cup structure without the need for laborious and inconvenient finger removal, thus avoiding contact with residual liquid medicine. This medicine cup structure also prevents spillage caused by excessive pressure applied to the BFS container during assembly or use, thus enabling nebulizers using this medicine cup structure to produce the desired nebulization effect. [Previous Technology]

[0002] Nebulizers are mainly used to atomize liquids into small droplets, which are then dispersed into the atmosphere to achieve specific effects. For example, aromatic liquids are atomized into droplets and dispersed into indoor spaces to improve environmental comfort, such as nebulizers used for indoor fragrances. Alternatively, medical liquids can be atomized for nebulization therapy, where the atomized liquid is inhaled by the patient and indirectly absorbed into the bloodstream through the alveoli to treat diseases of the respiratory tract, brain, human organs, immune system, eyes, etc., or directly atomized onto the affected area, such as nebulizers used in ENT clinics.

[0003] Existing nebulizers, such as those disclosed in Taiwan Invention Patent I723765 (hereinafter referred to as Document 1), include a container (or medicine cup) for storing liquid (or medicine solution) and a vibration mechanism for atomizing the medicine solution. With such existing nebulizers, the user must inject the medicine solution into the container before use. Therefore, the user must first measure the amount of medicine solution to be used, or if a different medicine solution is to be changed, the user must first disassemble and clean the container before using it again, which is inconvenient to use.

[0004] To improve upon the problems of the aforementioned Document 1, Taiwan Invention Patent I734450 (hereinafter referred to as Document 2) provides a medicine cup structure for opening a BFS container filled with liquid medicine. According to Document 2, the BFS container is inserted into the medicine cup structure through a flat (or plate-like) opening, and then the front end of the BFS container is rotated relative to the main body of the BFS container to open the structure and allow the liquid medicine to enter the medicine cup structure. However, during the operation, the user must hold the main body of the BFS container to align the flat front end of the BFS container with the flat opening of the aforementioned medicine cup structure. This is not a major problem for medical personnel, but it is difficult for elderly people or seriously ill patients with trembling hands to perform the aforementioned alignment. Furthermore, Reference 2 requires force to be applied to the main body of the BFS container to rotate it. Since the BFS container is a resilient and flexible plastic material such as polyethylene (PE) or polypropylene (PP), users often apply excessive force to the main body of the BFS container to open it smoothly, leading to medication spillage. This prevents nebulizers using a cup structure from producing the desired atomization effect. Reference 2 also poses a risk of medication overflowing from the cup structure, as the flat opening is normally connected to the external environment. Therefore, when the cup structure is tilted, the medication can flow out of the flat opening into the external environment. In addition, the medication is more easily contaminated by the external environment. Moreover, Reference 2 does not disclose the mechanism that causes the front end of the BFS container to rotate relative to the main body for opening; therefore, the technology disclosed in Reference 2 is not detailed enough and is open to discussion. [Summary of the Invention]

[0005] In view of the above, the object of the present invention is to provide a medicine cup structure and an nebulizer using the medicine cup structure. The medicine cup structure is used to open a BFS container filled with liquid medicine. The medicine cup structure can simultaneously open the BFS container during assembly, thus providing a BFS container opening mechanism without additional alignment, especially for users with trembling hands. Preferably, the medicine cup structure remains liquid-tight after the BFS container is opened, preventing liquid medicine from flowing out of the medicine cup structure when tilted and avoiding contamination of the liquid medicine by the external environment. The medicine cup structure also prevents spillage caused by the user accidentally applying excessive pressure to the body of the BFS container during assembly or use. Therefore, the nebulizer using the medicine cup structure can produce the desired nebulization effect. Another object of the present invention is to provide an assembly method for the medicine cup structure.

[0009] According to the above technical features, the first accommodating portion further includes a first elongated groove structure, and the other end of the cylindrical structure is connected to the first elongated groove structure.

[0010] According to the above technical features, the second receiving portion includes a second elongated groove structure.

[0011] According to the above technical features, the mounting component further has a mounting component closed end opposite to the opening end of the mounting component, one end of the first long groove structure is the mounting component closed end, and the mounting component closed end is not connected to the cylindrical structure.

[0012] According to the above technical features, the other end of the cylindrical structure is arc-shaped.

[0013] According to the above technical features, the second accommodating part is formed by protruding from the periphery of the cavity and / or the bottom of the cavity, or the second accommodating part is formed independently and then clamped to the periphery of the cavity and / or the bottom of the cavity.

[0014] Based on the above technical features, the mounting component further includes a window structure, which is formed on one side wall of the cylindrical structure, and the window structure is a transparent window or a hollowed-out window.

[0015] According to the above technical features, the liquid accumulation cavity system is provided with an elastic colloid covering the surface of the second accommodating part.

[0016] According to the above technical features, a microporous membrane is also provided at the bottom of the cavity, and when the mounting component is assembled with the liquid accumulation cavity, the medicine cup structure is in a liquid-tight state.

[0017] According to the above technical features, the rigidity of the mounting component and / or the liquid accumulation cavity is greater than that of the BFS container.

[0018] According to the above technical features, the fact that the liquid storage component cannot rotate with its axis as the rotation axis means that the liquid storage component cannot rotate as a whole or can be twisted or rotated at an angle of less than 30 degrees.

[0019] Based on the above objectives, the present invention also provides an atomizing device, which includes the aforementioned medicine cup structure.

[0020] Based on the above objectives, the present invention also provides a method for assembling a medicine cup structure, applicable to opening a blow-fill-seal (BFS) container filled with a liquid medicine. The BFS container is a liquid storage component, which includes a second mounting portion and a liquid storage portion, wherein the liquid storage portion is connected to the second mounting portion. The liquid storage portion has a first end and a second end oppositely disposed thereon, and the end of the second end has a protrusion. The liquid medicine is filled in the liquid storage portion, and the protrusion is connected to the second mounting portion. The method for assembling the medicine cup structure includes the following steps: Step of providing a mounting component: Providing a mounting component, which includes a first receiving portion and a first connecting portion. The first connecting portion is connected to the first receiving portion. The first connecting portion has a threaded structure. The first receiving portion includes a cylindrical structure, and the first connecting portion is disposed at one end of the cylindrical structure. Step of providing a liquid storage component: The liquid storage portion of the liquid storage component is filled and secured within the cylindrical structure, preventing the liquid storage component from rotating about one of its axial directions. Step of providing a liquid accumulation cavity: A liquid accumulation cavity is provided, comprising a liquid accumulation space, a second receiving portion, and a second connecting portion. The liquid accumulation space is formed by a cavity periphery and a cavity bottom, with the cavity bottom connected to the cavity periphery. The second receiving portion is disposed within the liquid accumulation space and cannot rotate relative to the cavity periphery and / or the cavity bottom. The second connecting portion is disposed on the cavity periphery and has another threaded structure, which can rotate correspondingly with the other threaded structure to lock together. The locking step involves rotating the other threaded structure of the second coupling portion in a corresponding manner to the threaded structure of the first coupling portion, causing the mounting part and the liquid accumulation cavity to gradually approach each other until the second mounting portion is locked within the liquid accumulation space, and the liquid storage component cannot rotate around the axis of rotation without damaging it. The liquid outlet opening step involves continuously rotating the second coupling portion and the first coupling portion in a corresponding manner to further separate the second mounting portion from the protrusion or the second end of the liquid storage portion, creating a liquid outlet opening. At this time, the liquid stored in the liquid storage portion flows out from the liquid outlet opening and into the liquid accumulation space.

[0021] According to the above technical features, the liquid storage component further includes a first mounting portion, the two ends of which are respectively connected to the first mounting portion and the second mounting portion. The first mounting portion has a first plate-like structure, and the second mounting portion has a second plate-like structure. The first receiving portion further includes a first elongated groove structure, and the other end of the cylindrical structure is connected to the first elongated groove structure. The step of providing the mounting component involves inserting the first plate-like structure of the first mounting portion of the liquid storage component into the first elongated groove structure, and the first mounting portion is restricted within the first elongated groove structure and cannot rotate around the rotation axis.

[0022] According to the above technical features, the second receiving part includes a second long groove structure. The locking step causes the second plate-like structure of the second mounting part to be inserted into the second long groove structure, and the second mounting part is restricted within the second long groove structure and cannot rotate around the rotation axis.

Implementation Method

[0023] Please refer to Figure 1, which illustrates an embodiment of the nebulizer device of the present invention. The nebulizer device 1 of this embodiment includes a medicine cup structure 10, a vibration module 20 (see also Figure 9), an nebulizing chamber 30, a base 40, a power module 50, and a droplet guide 60. In this embodiment, the nebulizer device 1 is exemplified as a medical liquid nebulizer, but is not limited thereto.

[0024] The base 40 is L-shaped or straight. In this embodiment, the L-shaped base is used as an example. One end of the base 40 has a connecting channel 41, and the other end has a receiving chamber 42. The two ends of the connecting channel 41 are respectively connected to the medicine cup structure 10 and the atomizing chamber 30. The atomizing chamber 30 is located close to the receiving chamber 42 of the base 40, while the medicine cup structure 10 is located away from the receiving chamber 42. The vibration module 20 is located in the connecting channel 41, and the power module 50 is located in the receiving chamber 42 of the base 40 and is connected to the vibration module 20 via a wire (not shown in the figure). A switch located on the outer surface of the base 40 allows the user to turn on the power module 50 and the vibration module 20, so that the power module 50 supplies power to the vibration module 20.

[0025] Referring to Figure 2, the medicine cup structure 10 is disposed at the upper end of the connection channel 41 of the base 40 and can be detached from the connection channel 41 of the base 40. The medicine cup structure 10 can be designed to be disposable (single-use) to avoid contamination between different drugs when reused. The vibration module 20, the base 40, and the power module 50 are designed to be reusable to save on usage costs. The atomizing chamber 30 and the atomizing droplet guide 60 can be designed to be disposable or reusable as needed. The medicine cup structure 10 can be connected to the base 40 by having a protrusion 10a for engaging with a groove 41a on the inner wall of the connection channel 41, so that the medicine cup structure 10 is positioned in the connection channel 41 of the base 40. For example, when the medicine cup structure 10 rotates in the forward direction, the protrusion 10a can engage with the groove 41a, thereby connecting the medicine cup structure 10 with the base 40. When it is necessary to separate the medicine cup structure 10 from the base 40, the medicine cup structure 10 can be rotated in the reverse direction, which makes it convenient for the user to operate.

[0026] Please refer to Figures 3, 4 and 5. The medicine cup structure 10 of this embodiment includes a mounting member 11 and a liquid collection cavity 13. The mounting member 11 is detachably connected to the liquid collection cavity 13, and a liquid storage member 12 is disposed in the mounting member 11 and extends into the liquid collection cavity 13. The liquid storage member 12 is a BFS container filled with medicine liquid L (please also refer to Figure 8 or Figure 9).

[0027] The BFS container is a resilient and flexible plastic object, such as polyethylene (PE) or polypropylene (PP). For example, the liquid storage component 12 of the BFS container includes a first mounting part 121, a second mounting part 122, and a liquid storage part 123. The liquid storage part 123 is cylindrical and its two ends are respectively connected to the first mounting part 121 and the second mounting part 122. The liquid storage part 123 has a first end 1231 and a second end 1232 disposed opposite to each other. The first end 1231 and the second end 1232 have an arc-shaped structure, and the end of the second end 1232 has a cylindrical protrusion 1233 with a diameter smaller than that of the liquid storage part 123. The liquid L (please refer to Figure 8) is filled in the liquid storage part 123. The protrusion 1233 is connected to the second mounting portion 122. The first mounting portion 121 may have a first plate-like structure, and the second mounting portion 122 may have a second plate-like structure. The first mounting portion 121 is connected to the first end portion 1231 and is parallel to the axial direction (length extension direction of the cylinder) of the cylindrical liquid storage portion 123. The second mounting portion 122 is only connected to the protrusion 1233 of the second end portion 1232. The structure of the second mounting portion 122 on both sides of the protrusion 1233 is symmetrical and separated from the second end portion 1232. Therefore, when the second mounting portion 122 is clamped and rotated with the axial direction of the liquid storage portion 123 as the rotation axis, the protrusion 1233 will separate from the second mounting portion 122 to generate the liquid outlet opening 1234 (see Figure 8 for reference). Of course, in another embodiment, the protrusion 1233 may also be designed to separate from the second end portion 1232 to generate the liquid outlet opening 1234. Alternatively, in another embodiment, the protrusion 1233 or the second end 1232 may be designed to break to create a liquid outlet 1234. In other words, when the second mounting portion 122 is clamped and rotated with the axial direction of the liquid storage portion 123 as the axis of rotation, the liquid storage portion 123 is at least partially broken to create a liquid outlet 1234. For example, the second mounting portion 122 may be at least partially separated from the liquid storage portion 123, the protrusion 1233, or the second end 1232 to create a liquid outlet 1234. It should be noted that in an embodiment where the liquid storage member 12 is structurally symmetrical, the axial rotation axis of the liquid storage portion 123 and the axial rotation axis of the liquid storage member 12 are the same. Since most BFS containers are designed with a structurally symmetrical embodiment, for the sake of simplicity, the axial or rotation axis system described below may refer to the axial rotation axis of the liquid storage portion 123 and / or the liquid storage member 12.

[0028] The mounting component 11 includes a first receiving portion 111 and a first connecting portion 112. The first receiving portion 111 is a hollow tube, and the mounting component 11 has a mounting component open end 11a. More preferably, the mounting component 11 also has a mounting component closed end 11b opposite to the mounting component open end 11a. The first connecting portion 112 is connected to the first receiving portion 111. For example, the first connecting portion 112 is disposed in the first receiving portion 111. The first receiving portion 111 includes a cylindrical structure 111a and a first elongated groove structure 111b. A first connecting portion 112 is disposed at one end of the cylindrical structure 111a (e.g., the opening end 11a of the mounting component). The other end of the cylindrical structure 111a is arc-shaped and connected to the first elongated groove structure 111b. Since the other end of the cylindrical structure 111a is arc-shaped, it is advantageous to guide the first mounting portion 121 into the first elongated groove structure 111b, so that the first mounting portion 121 is confined within the first elongated groove structure 111b and cannot rotate about the axial direction of the liquid storage portion 123 as the rotation axis. The cylindrical structure 111a and the first elongated groove structure 111b together form a hollow tube, and preferably, the end of the first elongated groove structure 111b is the closed end 11b of the mounting component, which is not connected to the cylindrical structure 111a. Furthermore, preferably, the first connecting portion 112 is disposed inside the cylindrical structure 111a, and more preferably, the first connecting portion 112 is circumferentially disposed inside the cylindrical structure 111a. Taking the first connecting portion 112 having a threaded structure as an example, in this embodiment, the first connecting portion 112 has an internal threaded structure. Preferably, the first receiving portion 111 and the first connecting portion 112 are integrally formed, for example, manufactured by an injection molding process. In other words, preferably, the mounting member 11 is integrally formed. Preferably, the rigidity of the first receiving portion 111 and / or the first connecting portion 112 is greater than the rigidity of the liquid reservoir 123. Therefore, the first receiving portion 111 and / or the first connecting portion 112 is more resistant to deformation than the liquid reservoir 123. That is, when subjected to external forces or pressures, such as the combined clamping force of multiple fingers, the first receiving portion 111 and / or the first connecting portion 112 is better able to maintain its shape and structure than the liquid reservoir 123. Preferably, the material of the first receiving portion 111 and / or the first connecting portion 112 may be polystyrene, polycarbonate, acrylic resin, polyethylene terephthalate or high-density polypropylene.

[0029] The liquid accumulation cavity 13 is a hollow cavity, which includes a liquid accumulation space 130, a second receiving part 131 and a second connecting part 132. The liquid accumulation space 130 is formed by a cavity peripheral wall 130a surrounding a cavity bottom 130b. The cavity bottom 130b is connected to the cavity peripheral wall 130a and forms a cavity closed end 13b with the microporous membrane 133 described later. The cavity open end 13a is located on the cavity peripheral wall 130a and is disposed opposite to the cavity closed end 13b. The second receiving portion 131 is disposed within the liquid accumulation space 130. For example, the second receiving portion 131 is formed by protruding from the cavity peripheral wall 130a and / or the cavity bottom 130b and cannot rotate relative to the cavity peripheral wall 130a and / or the cavity bottom 130b. In another embodiment, the second receiving portion 131 is independently formed and then clamped to the cavity peripheral wall 130a and / or the cavity bottom 130b and cannot rotate relative to the cavity peripheral wall 130a and / or the cavity bottom 130b. The second receiving portion 131 may include a second elongated groove structure 131a. During subsequent operation, the second mounting portion 122 can be inserted into the second elongated groove structure 131a and clamped and restricted within the second elongated groove structure 131a, preventing it from rotating about the axis of rotation of the liquid storage portion 123. The second connecting portion 132 is disposed on the periphery wall 130a of the cavity and has a threaded structure. In this embodiment, the second connecting portion 132 is disposed on the outer surface of the periphery wall 130a of the cavity and has an external threaded structure. During subsequent operation, the second connecting portion 132 can be combined with the first connecting portion 112, for example, permanently or temporarily by means of engagement, meshing or screwing, but is not limited thereto. In this embodiment, the second connecting portion 132 and the first connecting portion 112 each have a threaded structure and can be locked to each other by corresponding rotation of their respective threaded structures. During this mutual rotation, the mounting member 11 and the liquid accumulation cavity 13 gradually approach and tighten. This approach helps the second mounting portion 122 to be inserted into the second elongated groove structure 131a. Once the second mounting portion 122 is inserted into the second elongated groove structure 131a, it is clamped and restricted within the structure and cannot rotate about the axial direction of the liquid storage portion 123. Therefore, the continued mutual rotation of the second connecting portion 132 and the first connecting portion 112 results in tightening, causing the second mounting portion 122 to separate from the protrusion 1233, creating a liquid outlet opening 1234 (see also Figure 8). In this embodiment, the second connecting portion 132 has an external thread structure, while the first connecting portion 112 has an internal thread structure. A microporous membrane 133 is also provided at the bottom of the cavity 130b. The characteristics, materials, functions and operating mechanisms of the microporous membrane 133 have been disclosed in Reference 1 and Reference 2, so they will not be repeated here. Usually, the microporous membrane 133 is made of a different material from the bottom of the cavity 130b.Preferably, the cavity peripheral wall 130a, cavity bottom 130b, second receiving portion 131, and second connecting portion 132 are integrally formed, for example, by injection molding. In other words, preferably, except for the microporous membrane 133, the liquid accumulation cavity 13 is integrally formed. Preferably, the rigidity of the cavity peripheral wall 130a, cavity bottom 130b, second receiving portion 131, and / or second connecting portion 132 is greater than the rigidity of the liquid storage portion 123. Preferably, the material of the cavity peripheral wall 130a, cavity bottom 130b, second receiving portion 131, and / or second connecting portion 132 can be polystyrene, polycarbonate, acrylic resin, polyethylene terephthalate, or high-density polypropylene. It should be noted that the mounting component 11 and the liquid accumulation cavity 13 may be made of the same or different materials. Preferably, the mounting component 11 and the liquid accumulation cavity 13 are made of the same material to save on the types of materials and costs during production.

[0030] When assembling the medicine cup structure 10, the assembly method of the medicine cup structure shown in Figures 6, 7 and 8 is as follows: First, the first mounting part 121 (first plate-shaped structure) of the liquid storage component 12 enters the cylindrical structure 111a from the opening end 11a of the mounting part, and is inserted into the first long groove structure 111b through the cylindrical structure 111a, so that the liquid storage part 123 is accommodated in the cylindrical structure 111a. As mentioned earlier, since the other end of the cylindrical structure 111a is arc-shaped, it facilitates guiding the first mounting part 121 into the first elongated groove structure 111b without requiring alignment, thus greatly assisting users with hand tremors. Furthermore, it should be noted that even if the other end of the cylindrical structure 111a is not arc-shaped (e.g., flat), the first mounting part 121 can still enter the first elongated groove structure 111b without alignment by rotating the liquid storage component 12 via the liquid accumulation chamber 13 during subsequent assembly, thus also greatly assisting users with hand tremors. At this time, the first mounting part 121 is confined within the first elongated groove structure 111b and cannot rotate about the axis of rotation of the liquid storage part 123. In other words, the entire liquid storage component 12 (BFS container) is confined within the first elongated groove structure 111b and cannot rotate about the axis of rotation of the liquid storage part 123. Next, the external thread structure of the second joint 132 and the internal thread structure of the first joint 112 are rotated in correspondence to each other, so that the mounting part 11 and the liquid accumulation cavity 13 gradually approach each other until the second mounting part 122 is inserted into the second long groove structure 131a. As mentioned above, at this time, since the second mounting part 122 has been inserted into the second long groove structure 131a, it is restricted within the second long groove structure 131a and cannot rotate around the axis of rotation of the liquid storage part 123. Next, the second joint 132 and the first joint 112 continue to rotate in a corresponding manner, that is, the mounting part 11 and the liquid accumulation cavity 13 continue to rotate in a corresponding manner, thereby further separating the second mounting part 122 from the protrusion 1233 to generate the liquid outlet 1234. At this time, the medicine L stored in the liquid storage part 123 flows out from the liquid outlet 1234 and enters the liquid accumulation space 130 in the liquid accumulation cavity 13. Based on the design of the microporous membrane 133 disclosed in Document 1 and Document 2, when the vibration module 20 is not started and the vibration member 21 is not vibrating, the medicine L will not pass through the microporous membrane 133 and flow out to the external environment or the atomizing cavity 30 described later.

[0031] Therefore, the medicine cup structure 10 can open the liquid reservoir 12 (BFS container) simultaneously during assembly, so the medicine cup structure 10 provides a liquid reservoir 12 (BFS container) opening mechanism that does not require additional alignment, especially for users with trembling hands. In addition, during and after opening the liquid reservoir 12, the user holds the mounting part 11 and the liquid collection chamber 13 with their hands and rotates them in a corresponding manner without touching the liquid reservoir 12 (BFS container). Furthermore, since the rigidity of the mounting part 11 and the liquid collection chamber 13 is greater than that of the liquid reservoir 12, the entire medicine cup structure 10 can also prevent the user from accidentally applying too much pressure to the main body (liquid reservoir 123) of the liquid reservoir 12 (BFS container) during assembly or use, which can cause the medicine to spill. This allows the nebulizer 1 using the medicine cup structure 10 to produce the expected nebulization effect. For example, as shown in Figure 9, the liquid medicine L entering the liquid accumulation chamber 13 accumulates above the microporous membrane 133 located at the bottom of the liquid accumulation chamber 13. Then, the vibrating element 21 of the vibration module 20 vibrates, causing the liquid medicine L to atomize into multiple droplets. The atomizing chamber 30 includes a droplet inlet 31 and a droplet outlet 32 ​​(see Figure 1 for reference). The droplets enter the atomizing chamber 30 through the droplet inlet 31 and leave the atomizing chamber 30 through the droplet outlet 32. Referring again to Figure 1, the atomizing droplet guide 60 is connected to the droplet outlet 32 ​​of the atomizing chamber 30. The droplets enter the atomizing droplet guide 60 from the atomizing chamber 30 and are guided by the atomizing droplet guide 60 to diffuse in a predetermined direction.

[0032] It should be noted that, in this embodiment, when the mounting component 11, the liquid storage component 12 and the liquid accumulation cavity 13 are assembled as shown in Figure 8, that is, when the liquid storage component 12 is filled in the cylindrical structure 111a and the liquid accumulation space 130, the entire medicine cup structure 10 is in a liquid-tight state. That is, at this time, the medicine liquid L in the medicine cup structure 10 will not be affected by gravity and will not flow out of the medicine cup structure 10 when it is in a static state. Therefore, it can prevent the medicine liquid L from flowing out of the medicine cup structure 10 when it is tilted, so it can avoid the medicine liquid L from being contaminated by the external environment.

[0033] In another embodiment, referring to FIG10, the mounting component 11 may further include a viewing window structure 111c, which is formed on the side wall of the cylindrical structure 111a. The liquid storage portion 123 is exposed from the viewing window structure 111c for the user to view and identify. The viewing window structure 111c can be a transparent window, such as transparent acrylic or glass, to maintain the entire medicine cup structure 10 in a liquid-tight state; or, for cost-saving considerations, the viewing window structure 111c can be hollow. However, in this case, the medicine cup structure 10 may not be able to maintain a liquid-tight state, thus causing the problem of excessively high leakage rate of the liquid medicine L. The excessively high leakage rate will result in insufficient atomization of the liquid medicine L, further resulting in poor treatment effect. In another embodiment, the problem of excessive leakage rate can be solved. Referring to Figure 11, an elastic colloid S is added to the liquid accumulation cavity 13 to cover the surface of the second receiving portion 131, so that the elastic colloid S can abut against at least a portion of the periphery of the second end 1232 of the liquid storage portion 123. Therefore, the liquid medicine L can be better preserved in the liquid accumulation space 130, thus solving the problem of excessive leakage rate. Preferably, the elastic colloid S can abut against the entire 360-degree periphery of the second end 1232 of the liquid storage portion 123, thus sealing the liquid medicine L in the liquid accumulation space 130 and solving the problem of excessive leakage rate. The elastic colloid S can be made of silicone, for example, the elastic colloid S can be a silicone sheet or a silicone O-ring.

[0034] Various liquid storage components 12 (BFS containers) actually have a variety of different shapes. Therefore, based on the above detailed description, the main mechanism of the medicine cup structure 10 of the present invention can be understood as follows: First, without damaging the liquid storage component 12, the liquid storage component 12 is locked in the cylindrical structure 111a of the mounting component 11 and the liquid accumulation space 130 of the liquid accumulation cavity 13 so that it cannot rotate about the axis of rotation of the liquid storage part 123; then the liquid storage component 12 is damaged, which is to further force the mounting component 11 and the liquid accumulation cavity 13 to continue to rotate in a corresponding manner, thereby further causing the second mounting part 122 to separate at least partially from the liquid storage part 123, the protrusion 1233 or the second end 1232 to generate the liquid outlet opening 1234. Therefore, in another embodiment, the first receiving portion 111 includes a cylindrical structure 111a without the need for a first elongated groove structure 111b. In this case, it is sufficient that the cylindrical structure 111a prevents the liquid storage member 12 from rotating within the cylindrical structure 111a. For example, without damaging the liquid storage member 12, the liquid storage member 12 cannot rotate with its axial direction as the axis of rotation. A specific example could be that the liquid storage portion 123 of the liquid storage member 12 is a cuboid and the cylindrical structure 111a is also a cuboid with a hollow tube inside. The cross-section of the liquid storage part 123 of the liquid storage part 12 is elliptical, and the cross-section of the hollow tube in the cylindrical structure 111a is also elliptical and only slightly larger than the cross-section of the liquid storage part 123. Therefore, the liquid storage part 12 cannot rotate in the cylindrical structure 111a. For example, a limiting member is provided in the hollow tube of the cylindrical structure 111a. The limiting member can restrict the second mounting part 122 so that it cannot rotate about the axis of rotation of the liquid storage part 12.

[0035] In another embodiment, as long as the second receiving portion 131 can prevent the liquid storage member 12 from rotating within the liquid accumulation cavity 13, for example, without damaging the liquid storage member 12, the liquid storage member 12 cannot rotate with its axial direction as the rotation axis; apart from the example in the above embodiment where the second receiving portion 131 may include the second elongated groove structure 131a, other specific examples may be that the second receiving portion 131 is another limiting member, which can limit the second mounting portion 122 from rotating with the axial direction of the liquid storage member 12. For example, the limiting member may be a clamping member to clamp the second mounting portion 122 from rotating with the axial direction of the liquid storage member 12, or the limiting member may be a blocking body to block the second mounting portion 122 from rotating with the axial direction of the liquid storage member 12.

[0036] Therefore, based on the above detailed description, the assembly method of the medicine cup structure of the present invention can be understood as follows: the assembly method of the medicine cup structure is applicable to opening a blow-fill-seal (BFS) container filled with a liquid medicine L. The BFS container is a liquid storage component 12, which includes a second mounting part 122 and a liquid storage part 123. The liquid storage part 123 is connected to the second mounting part 122. The liquid storage part 123 has a first end 1231 and a second end 1232 disposed opposite to each other, and the end of the second end 1232 has a protrusion 1233. The liquid medicine L is filled in the liquid storage part 123, and the protrusion 1233 is connected to the second mounting part 122. The assembly method of the medicine cup structure includes the following steps.

[0037] Providing the mounting component step: A mounting component 11 is provided, the mounting component 11 includes a first receiving portion 111 and a first connecting portion 112, the first connecting portion 112 is connected to the first receiving portion 111, the first connecting portion 112 has a threaded structure, the first receiving portion 111 includes a cylindrical structure 111a, and the first connecting portion 112 is disposed at one end of the cylindrical structure 111a.

[0038] Step of providing a liquid storage component: The liquid storage portion 123 of the liquid storage component 12 is filled and secured in the cylindrical structure 111a, so that the liquid storage component 12 cannot rotate about one of the axes of the liquid storage component 12 as a rotation axis.

[0039] Step of providing a fluid accumulation cavity: A fluid accumulation cavity 13 is provided, the fluid accumulation cavity 13 includes a fluid accumulation space 130, a second receiving portion 131 and a second connecting portion 132. The fluid accumulation space 130 is formed by a cavity peripheral wall 130a surrounding a cavity bottom 130b. The cavity bottom 130b is connected to the cavity peripheral wall 130a. The second receiving portion 131 is disposed in the fluid accumulation space 130 and cannot rotate relative to the cavity peripheral wall 130a and / or the cavity bottom 130b. The second connecting portion 132 is disposed on the cavity peripheral wall 130a. The second connecting portion 132 has another threaded structure, and the threaded structure and the other threaded structure can rotate correspondingly to lock each other.

[0040] The locking step is performed by rotating the other threaded structure of the second joint 132 and the threaded structure of the first joint 112 in a corresponding manner, so that the mounting part 11 and the liquid accumulation cavity 13 gradually approach each other until the second mounting part 122 is locked in the liquid accumulation space 130, and the liquid storage part 12 cannot be rotated around the rotation axis without damaging the liquid storage part 12.

[0041] Step of generating liquid outlet: The second joint 132 and the first joint 112 are continuously rotated in correspondence with each other, so that the second mounting part 122 and the liquid storage part 123 are at least partially separated to generate a liquid outlet 1234. At this time, the medicine L stored in the liquid storage part 123 flows out from the liquid outlet 1234 and enters the liquid accumulation space 130.

[0042] It should be noted that the aforementioned steps are not necessarily in the order described above, and the user may adjust the order of the steps according to the actual usage situation. In addition, the aforementioned statement that the liquid reservoir 12 cannot be rotated with its axis as the axis of rotation, or cannot be rotated with the axis of rotation of the liquid reservoir 12, or can be rotated with the axis of rotation of the liquid reservoir 123, refers to the inability to rotate as a whole without damaging the liquid reservoir 12, or the ability to twist or rotate at an angle of less than 30 degrees.

[0043] In summary, the medicine cup structure of the present invention can indeed be used to open a BFS container filled with liquid medicine. Furthermore, the medicine cup structure can simultaneously open the BFS container during assembly. Therefore, especially for users with trembling hands, the medicine cup structure provides a BFS container opening mechanism that does not require additional alignment. Preferably, the medicine cup structure remains liquid-tight after the BFS container is opened, thus preventing liquid medicine from flowing out of the medicine cup structure when tilted and avoiding contamination of the liquid medicine by the external environment. The medicine cup structure also prevents spillage caused by the user accidentally applying excessive pressure to the body of the BFS container during assembly or use. Therefore, the nebulizer using the medicine cup structure can produce the desired nebulization effect. In addition, the medicine cup structure may further include a viewing window structure that exposes the body of the BFS container for the user to view and identify.
