Description

Technology Field

[0001] The present invention relates to a cap assembly for a vial, and more specifically, to a cap assembly for a vial that is coupled to the neck of a vial to seal the contents while simultaneously being easily opened with a small amount of force by utilizing the lever principle. Background Technology

[0002] Vials are small glass or plastic bottles used to hold liquid medicines, health supplements, beverages, etc. They are widely used with a rubber cap pressed into the opening rather than a screw-on, and an aluminum cap sealed by a clamp. Due to their high sealing reliability, these vials are widely used for packaging pharmaceuticals, injectables, and health drinks.

[0003] FIG. 1 is a cross-sectional example illustrating the structure of a cap (20) of a conventional vial (10). As illustrated, the conventional vial (10) is sealed by pressing a rubber cap (21) into the bottle opening (11) and then placing an aluminum cap (23) over it and clamping it to the bottle opening (11).

[0004] At this time, a vertically protruding column (23a) is provided in the center of the upper surface of the aluminum cap (23), and the user presses the column (23a) laterally with their hand to tear the aluminum cap (23) and separate the rubber cap (21) to open the vial bottle (10).

[0005] This method of opening the cap (20) utilizes the column (23a) as a lever. At this time, the point of application of the lever is the distance (R1) between the center of the column (23a) and the edge where the aluminum cap (23) and the bottle opening (11) come into contact.

[0006] However, this conventional cap opening method has limitations in that the distance (R1) of the lever point of application is very short, being only the radius of the bottle opening (11), and the height (h1) of the column (23a) is relatively low, so a considerable force is required to break the seal of the aluminum cap (23). In particular, in the case of women, the elderly, and children with weak grip strength, it frequently occurs that they cannot properly open the cap (20) because they cannot sufficiently press the column (23a).

[0007] In addition, if the cap is not opened, there is a risk of safety accidents, such as dropping the vial (10) and spilling the contents (A) while forcibly applying force to the edge of the aluminum cap (23), or scratching fingers on the sharp edge of the aluminum cap (23).

[0008] To solve this problem, a method was used to extend the length of the column by attaching a separate tubular opener (30) to the protruding column (23a) of the aluminum cap (23). Since the height (h2) of the opener (30) is higher than the height (h1) of the column, there is an advantage that the aluminum cap (23) can be opened with relatively less force.

[0009] However, even if an opener (30) is used, the distance of the lever point is still the radius (R1) of the bottle opening (11), so there is inconvenience, and if the opener is lost or not carried, it must still be opened by hand, so the problem of difficulty in opening for users with weak strength is not fundamentally resolved.

[0010] In addition, since conventional vials are structured to contain only liquid medicine (A) inside, there was no method to simultaneously package or carry solid medicines that must be taken together with liquid medicine, such as effervescent vitamins, tablets, and capsules.

[0011] Consequently, users faced the inconvenience of having to separate the liquid medication into a vial and the solid medication into separate containers to carry them separately, and there was the hassle of having to carry both medications at all times, especially when traveling or going out.

[0012] For reference, this project was carried out with support from the Ministry of Trade, Industry and Energy's Gangwon Hupyeong Industrial Complex Smart Logistics Platform Construction and Operation Project (Project period: May 1, 2025 – December 31, 2027). Prior art literature

[0014] Reference 1. Republic of Korea Published Utility Model Publication No. 20-2025-0000891, "Pill storage container combined with aluminum cap column of vial bottle" The problem to be solved

[0015] The objective of the present invention is to solve the aforementioned problem by providing a vial bottle cap assembly that increases the lever point distance compared to conventional methods, thereby enabling women, the elderly, and children with weak physical strength to easily open a vial bottle with minimal force without the need for separate tools.

[0016] Another objective of the present invention is to provide a vial cap assembly that has an internal pharmaceutical storage space to store a solid pharmaceutical product separately from the liquid pharmaceutical product contained in the vial, thereby allowing for convenient portability.

[0017] Another objective of the present invention is to provide a vial bottle cap assembly that allows the vial bottle to be opened with a small amount of force by using a cap cover formed with pressure ribs that are in close contact with the aluminum cap, thereby ensuring that the pressure applied by the user is fully transmitted to the aluminum cap.

[0018] The above-mentioned objectives and various advantages of the present invention will become more apparent to those skilled in the art from the preferred embodiments of the present invention. means of solving the problem

[0020] The objective of the present invention can be achieved by a vial cap assembly that seals the opening of a vial bottle. The vial cap assembly of the present invention is characterized by comprising: a rubber cap (110) having a press-fit projection (111) formed thereon that is press-fitted into the opening of the bottle; an aluminum cap (120) that covers the upper part of the rubber cap (110) and seals the outer periphery of the opening of the bottle (11), and is provided with a protruding column (123) that protrudes upward from the center of the upper surface; and a cap cover (130) that is coupled to the opening of the bottle to cover the outside of the aluminum cap (120), and is provided to have a height greater than that of the protruding column (123) so as to form a medicine storage space (132) inside.

[0021] According to one embodiment, the cap cover (130) may include: a cylindrical cover body (131) that is provided to correspond to the shape of the aluminum cap (120) and is coupled to the upper part of the bottle opening to surround the outside of the aluminum cap (120); an upper cover (135) that is detachably coupled to the upper part of the cover body (131); an aluminum cap fitting plate (134) that is horizontally coupled to the inside of the cover body (131) and contacts and presses the upper surface of the aluminum cap (120); and a column fitting tube (136) that protrudes from the central area of ​​the aluminum cap fitting plate (134) and accommodates the protruding column (123) in contact with the inside.

[0022] According to one embodiment, when a pressure is applied upward by a user's finger on the side of the cap cover (130), the lower side wall of the cap cover (130) opposite to the direction in which the finger contacts comes into contact with the bottle opening (11) and can function as a point of action for the lever.

[0023] According to one embodiment, the height of the cap cover (130) may be formed to be 1.5 to 2.5 times higher than the height of the protruding column (123).

[0024] According to one embodiment, a plurality of pressure ribs (138) may be provided on the lower inner wall surface of the cover body (131), protruding a certain height toward the radially inner side along the circumferential direction to press the aluminum cap (120) against it. Effects of the invention

[0026] The vial bottle cap assembly according to the present invention combines a cup-shaped cap cover with the upper part of an aluminum cap, and when a user's finger force is applied to the cap cover, the distance of the lever point of application can be secured to be significantly larger than when pressing the protrusion of a conventional aluminum cap, so that even women, the elderly, and children with weak grip strength can easily open the vial bottle with minimal force by simply pressing the side of the cap cover with their fingers without a separate opener.

[0027] In addition, the cap assembly of the present invention is formed such that the height of the cap cover is higher than the height of the protruding column, so that the effect of expanding the distance of the lever point of application and the increase in the lever moment due to the increase in the pressure height act in combination, thereby further reducing the force required by the user when opening the vial bottle.

[0028] In addition, the cap assembly of the present invention is provided with a plurality of pressure ribs along the circumferential direction on the lower inner wall surface of the cover body so as to be in close contact with the outer wall surface of the aluminum cap. When a user presses the side of the cap cover, the force is directly transmitted to the outer wall surface of the aluminum cap through the pressure ribs. As a result, the aluminum cap rotates upward as a whole with the cap cover, causing the sealing of the aluminum cap to break, thereby separating the press-fit projection of the rubber cap from the bottle opening together, ensuring secure opening.

[0029] In addition, the cap assembly of the present invention is provided with a storage space for medicine inside the cap cover and an upper cover (135) that can be opened and closed on the top, so the user can easily put in and take out solid medicine contained in the liquid storage space by separating the upper cover, making it convenient.

[0032] To fully understand the present invention, preferred embodiments of the invention are described with reference to the accompanying drawings. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. These embodiments are provided to more completely explain the present invention to those with average knowledge in the art. Accordingly, the shapes of elements in the drawings may be exaggerated to emphasize clearer explanations. It should be noted that in each drawing, identical components may be depicted with the same reference numeral. Detailed descriptions of known functions and configurations that are deemed to unnecessarily obscure the essence of the present invention are omitted.

[0034] FIG. 2 is a perspective view showing a state in which a cap assembly (100) according to the present invention is coupled to a vial (10), FIG. 3 is a cross-sectional example showing the cross-sectional configuration of FIG. 2, FIG. 4 is an exploded perspective view showing the configuration of the cap assembly (100) disassembled, and FIG. 5 is a cross-sectional example showing the process of a user opening the vial (10) by pressing the cap assembly (100).

[0035] The cap assembly (100) of the present invention seals the opening (11) of a vial bottle (10) and allows a user to easily open the vial bottle (10) with minimal force. To this end, the cap assembly (100) according to the present invention includes a rubber cap (110) having a press-fit projection (111) formed thereon that is press-fitted into the opening (11) of a vial bottle (10), an aluminum cap (120) that covers the upper part of the rubber cap (110) and seals the outer periphery of the opening (11), and is provided with a protruding column (123) that protrudes upward from the center of the upper surface, and a cap cover (130) that is coupled to the opening to cover the outside of the aluminum cap (120), is provided to have a height greater than that of the protruding column (123), and has a medicine storage space (132) formed inside.

[0036] The cap assembly (100) of the present invention is additionally provided with a cap cover (130) over an aluminum cap (120). The cap cover (130) is provided in a cylindrical shape that surrounds the bottle opening (11). Accordingly, when a user holds the cap body (131) with their hand and applies pressure to open the cap assembly (100) as shown in FIG. 5, the lever point distance (R2) corresponds to the outer diameter of the bottle opening (11), so it becomes twice as large as the radius of the bottle opening (11), which is the conventional lever point distance (R1). Accordingly, when a user applies a horizontal pressure to the side of the cap cover (130), the sealing of the aluminum cap (120) can be broken by the lever principle with a much smaller force than when applying pressure to the protrusion (23a) of the conventional cap (20) shown in FIG. 1, thereby separating the entire cap assembly (100) from the bottle opening (11).

[0038] The rubber cap (110) primarily seals the bottle opening (11) to prevent the liquid medicine (A) inside the vial (10) from leaking out of the cap assembly (100). Since the vial (10) is manufactured as a small glass bottle, it is difficult to machine screw threads on the surface of the vial (10), and the machining process is costly. Therefore, the rubber cap (110) is used to block the vial (10) to provide primary sealing.

[0039] The rubber cap (110) is provided in the shape of a disc made of rubber material having an outer diameter corresponding to the outer diameter of the bottle opening (11). A pressing projection (111) is integrally formed on the lower part of the rubber cap (110), protruding downward with an outer diameter corresponding to the inner diameter of the bottle opening (11) and inserted into the bottle opening (11).

[0040] The press-fit projection (111) is formed to protrude downward from the center of the rubber cap (110) and is inserted into the inner opening of the bottle opening (11) in a press-fit manner. The press-fit projection (111) is formed with an outer diameter slightly larger than the inner diameter of the bottle opening (11) so that when inserted into the bottle opening (11), it is pressed against the inner wall of the bottle opening (11) and forms a press-fit connection that is tightly sealed.

[0041] Through this forced-fit connection, the indentation projection (111) comes into full contact with the inner wall of the bottle opening (11), thereby fundamentally preventing the liquid medicine (A) from leaking out. Since the indentation projection (111) is made of rubber and has elasticity, the adhesion force is maintained regardless of fine irregularities or shape deviations on the inner wall of the bottle opening (11).

[0043] The aluminum cap (120) covers the upper part of the rubber cap (110) that is pressed into the opening (11) of the vial (10) and seals the outer periphery of the opening (11) to secure the rubber cap (110) so that it does not detach from the opening (11) and prevents external contamination. The aluminum cap (120) covers the rubber cap (110) and the outer periphery of the opening (11) in a clamping manner from the upper part of the opening (11) to maintain the sealed state of the rubber cap (110).

[0044] The aluminum cap (120) is integrally formed with a side wall (121) that surrounds the outer circumference of the bottle opening (11) and a protruding column (123) that protrudes vertically from the center of the upper surface of the aluminum cap (120).

[0045] The aluminum cap (120) has an upper surface and side walls (121) that surround the upper surface and both sides of the rubber cap (110), and the side walls (121) are formed to extend downward in a shape that surrounds the outer periphery of the bottle opening (11) as shown in FIG. 3. The side walls (121) are manufactured by forming a thin plate made of aluminum material, and the lower end is bent inward at the boundary between the bottle opening (11) and the bottle neck (13) and clamped to the outer periphery of the bottle opening (11). By this clamping structure, the aluminum cap (120) is firmly fixed to the bottle opening (11), and the press-fit seal of the rubber cap (110) is maintained.

[0046] As shown in FIG. 5, when the cap assembly (100) is opened by the user's pressure, the aluminum cap (120) can be separated from the bottle opening (11) by the shear force concentrated on the clamping portion of the side wall (121) when the cap cover (130) rotates with the lower coupling portion (131a) as the lever point, causing the clamping structure to break.

[0047] The protruding column (123) is formed to protrude vertically to a certain height toward the upper center area of ​​the aluminum cap (120).

[0049] The cap cover (130) is attached to cover the top of the aluminum cap (120), allowing the user to easily detach the aluminum cap (120) with minimal force without the need for a separate opener. Additionally, the cap cover (130) stores solid medicine (B) in the internal medicine storage space (132), allowing it to be carried together with the liquid medicine (A) inside the vial (10).

[0050] The cap cover (130) is formed in the shape of a cylindrical cup with an open bottom. The cap cover (130) includes a cylindrical cover body (131) that is coupled to the upper part of the bottle opening (11) to surround the outside of the aluminum cap (120), an upper cover (135) that is detachably coupled to the upper part of the cover body (131), an aluminum cap fitting plate (134) that is horizontally coupled to the inside of the cover body (131) to contact and press the upper surface of the aluminum cap (120), and a column fitting tube (136) that protrudes from the central area of ​​the aluminum cap fitting plate (134) and is coupled to surround the protruding column (123).

[0052] The cap body (131) is provided to correspond to the shape of the aluminum cap (120) and is coupled to wrap around the outside of the aluminum cap (120).

[0053] The outer diameter of the cap body (131) is formed to be larger than the outer diameter of the bottle opening (11) by the thickness of the aluminum cap (120). As a result, as shown in FIG. 3, the lower connecting portion (131a) formed at the bottom of the cap body (131) is positioned to surround the outside of the side wall (121) of the aluminum cap (120), and the lever point distance (R2) is formed to be larger than the conventional lever point distance (R1) shown in FIG. 1.

[0054] Additionally, the height (h3) of the cap body (131) is formed to be greater than the height (h1) of the protruding column (123) of the aluminum cap (120), so that when a user presses the cap cover (130), force can be applied from a higher position, thereby increasing the lever moment and reducing the force required for opening. The cap body (131) can be made of plastic, metal, composite material, etc.

[0055] Here, it is preferable that the height (h3) of the cap body (131) be formed in a range of 1.5 to 2.5 times the height (h1) of the protruding column (123) so that the minimum force can be applied when the user applies pressure.

[0056] According to the lever principle, the opening moment when opening the cap cover (130) is expressed as the product of the pressure applied by the user's hand to the cap cover (130) and the height (h3) of the cap cover (130). That is, the higher the height of the cap cover (130), the greater the opening moment can be generated with the same pressure. However, if the height of the cap cover (130) is excessively high, the overall height of the cap assembly (100) increases excessively, which may reduce the portability and structural stability of the product.

[0057] If the height (h3) of the cap body (131) is less than 1.5 times the height (h1) of the protruding column (123), there is a disadvantage in that the effective height at which a user can apply pressure with their hand to the side of the cap cover (130) is not sufficiently secured, so the lever moment may not reach the critical moment required for the sealing of the aluminum cap (120) to break, and the pill storage space is excessively reduced. In particular, for women, the elderly, and children with weak grip strength, the pressure required for opening is still excessive, so ease of opening is not sufficiently achieved.

[0058] On the other hand, if the height (h3) of the cap body (131) exceeds 2.5 times the height (h1) of the protruding column (123), the overall height of the cap assembly (100) increases excessively, the overall proportional balance with the vial bottle (10) is disrupted, and the risk of unintended opening occurs as the cap cover (130) is easily shaken laterally or unintentionally pressed by external force increases.

[0059] In addition, the center of gravity of the entire vial package, in which the cap assembly (100) is combined with the vial (10), shifts upward, causing it to tip over during storage and distribution, and the manufacturing cost of the cap cover (130) increases unnecessarily.

[0061] Meanwhile, the lower connecting portion (131a) formed at the bottom of the cap body (131) is in close contact with the outer side of the aluminum cap (120) along the lower circumferential direction of the cap body (131). The lower connecting portion (131a) is bent inward to cover the bottom of the side wall (121) of the aluminum cap (120), interlocking and sealing it. Through this sealing structure, the cap cover (130) covers the aluminum cap (120) and is firmly fixed to the bottle opening (11).

[0062] The lower connecting member (131a) is clamped to wrap around the side wall (121) of the aluminum cap (120) and is firmly fixed to the side wall (121) of the aluminum cap (120). It is preferable that the height of the lower connecting member (131a) be positioned to wrap around the joint portion between the aluminum cap (120) and the bottle opening (11), as shown in FIG. 3. The lower connecting member (131a) functions as a lever point when pressure is applied by the user's hand (f2) to the side of the cap cover (130), as shown in FIG. 5. As the lower connecting member (131a) contacts and supports the bottle opening (11), the cap cover (130) rotates, breaking the seal of the aluminum cap (120) and causing the aluminum cap (120) to open.

[0064] The aluminum cap insertion plate (134) is horizontally coupled to the interior of the cover body (131) and presses against the upper surface of the aluminum cap (120). The aluminum cap insertion plate (134), together with the column insertion tube (136), completely wraps around and tightly supports the aluminum cap (120) between the cover body (131), thereby transmitting pressure so that when a user presses against the outer wall of the cover body (131), the aluminum cap (120) is separated together with the cover body (131) by the pressure.

[0065] The aluminum cap insertion plate (134) is fixed to the inner wall of the cover body (131) to partition the internal space of the cover body (131), and when the cap cover (130) is coupled to the aluminum cap (120), it is pressed against the upper surface of the aluminum cap (120) to increase the binding force with the aluminum cap (120). In addition, a medicinal material storage space (132) is formed between the aluminum cap insertion plate (134) and the upper cover (135).

[0066] The column fitting tube (136) extends upward from the central region of the aluminum cap fitting plate (134) to enclose and accommodate the protruding column (123) of the aluminum cap (120) when the cap cover (130) is attached to the upper part of the aluminum cap (120). The protruding column (123) may be provided with a cross-section in the shape of a hexagon or an octagon, not just a circle. The column fitting tube (136) is provided with protruding columns (123) of various cross-sectional shapes in contact with the inner wall surface to accommodate the protruding columns (123) in close contact. Additionally, as an example, the shape of the inner wall surface of the column fitting tube (136) may be formed to correspond to the cross-sectional shape of the protruding column (123). That is, if the protruding column (123) is circular, the inner wall surface of the column fitting tube (136) may be formed in a circular shape, and if the protruding column (123) is hexagonal, the inner wall surface of the column fitting tube (136) may be formed in a hexagonal shape.

[0067] When the protruding column (123) is inserted into the column fitting tube (136), the two members are forcibly fitted and interlocked to constrain their positions, and the pressure applied by the user to the cover body (131) is transmitted to the protruding column (123) through the column fitting tube (136), and the protruding column (123) is supported to rotate together with the column fitting tube (136).

[0068] By the fitting connection of the column fitting tube (136) and the protruding column (123), the cap cover (130) and the aluminum cap (120) are bound to each other after joining, and when a user applies opening force to the cap cover (130), the aluminum cap (120) can be separated from the bottle opening (11) together with the cap cover (130).

[0069] The length of the column fitting tube (136) is formed to correspond to the height (h1) of the protruding column (123), so that when the protruding column (123) is completely received inside the column fitting tube (136), the lower surface of the aluminum cap fitting plate (134) is provided to be in close contact with the upper surface of the aluminum cap (120).

[0071] As shown in FIG. 4, the pressure rib (138) is a rod-shaped rib formed to protrude a certain height along the circumferential direction toward the radial inner side of the lower inner wall surface of the cover body (131). When the cap cover (130) is coupled to the aluminum cap (120), the pressure rib (138) adheres to the outer wall surface of the side wall (121) of the aluminum cap (120) and presses and restrains the aluminum cap (120). The inner diameter of the cover body (131) is formed to correspond to the outer diameter of the side wall (121). Since the pressure rib (138) protrudes inward from the inner wall surface of the cover body (131), when the cap cover (130) is attached to the outside of the aluminum cap (120), the pressure rib (138) is compressed between the outer wall surface of the side wall (121) of the aluminum cap (120) and the inner wall surface of the cover body (131), thereby restraining the aluminum cap (120) with strong force.

[0072] When a user applies pressure to the side of the cap cover (130) by hand in the direction in which the cap cover (130) is separated, the pressure rib (138) allows the pressure to be directly transmitted to the side wall (121) of the aluminum cap (120) through the pressure rib (138). As a result, the aluminum cap (120) moves as a whole with the cap cover (130) and rotates upward, and the shear force concentrated at the lower clamping portion of the side wall (121) of the aluminum cap (120) plastically deforms the aluminum material, causing the clamping structure to break and the aluminum cap (120) to be separated from the bottle opening (11).

[0073] Along with the separation of the aluminum cap (120), the press-fit projection (111) of the rubber cap (110) that was attached to the lower part of the aluminum cap (120) also detaches from the bottle opening (11), and the bottle opening (11) is completely opened.

[0074] Since the pressure ribs (138) are formed in multiple numbers along the circumferential direction, the contact area with the outer wall surface of the side wall (121) of the aluminum cap (120) is uniformly distributed along the circumferential direction, and the user's pressure is evenly transmitted to the entire outer wall surface of the aluminum cap (120), so that the aluminum cap (120) can rotate stably without eccentricity and be removed.

[0075] In the present invention, the pressure rib (138) is formed in a rod shape with a square cross-section, but depending on the case, it may be formed in a hemispherical or triangular shape.

[0077] The upper cover (135) is detachably coupled to the cover body (131) to open and close the upper opening of the cover body (131). The upper cover (135) opens and closes the medicine storage space (132) and allows solid medicine (B) to be inserted or removed. A body fitting projection (135a) is formed on the lower part of the upper cover (135) to correspond to the inner diameter of the cover body (131). The body fitting projection (135a) is a ring-shaped projection formed protruding from the lower part of the upper cover (135) and is inserted into the inner upper part of the cover body (131) as shown in FIG. 3, contacting the inner wall surface of the cover body (131) and detachably fixing the upper cover (135) to the cover body (131).

[0078] Meanwhile, a gripping projection (135b) is provided on the outer surface of the upper cover (135). The gripping projection (135b) is formed with a certain area radially outward on a part of the outer circumference of the upper cover (135) to grip or press when the user separates or attaches the upper cover (135) to the cover body (131). Through the gripping projection (135b), the user can easily attach and detach the upper cover (135) from the cover body (131).

[0080] As shown in FIG. 3, the medicine storage space (132) is formed between the upper cover (135) and the aluminum cap fitting plate (134). The medicine storage space (132) stores solid medicines (B), such as tablets, capsules, granules, and powders. Since solid medicines (B) can be stored in the medicine storage space (132), the liquid medicine (A) inside the vial (10) and the solid medicine (B) inside the cap cover (130) can be stored and carried together as a single package while maintaining a state of isolation from each other. This can be particularly useful in cases where two formulations of medicine, such as effervescent vitamins and powdered nutritional supplements, must be taken together.

[0082] Meanwhile, as shown in FIG. 6, the lower part of the cap body (131) of the cap cover (130) may be provided with an extension end (131b) that extends downward from the bottle opening (11) by a certain length (d). Compared to the cap cover (130) of the preferred embodiment shown in FIG. 3, the extension end (131b) extends further in the direction of the bottle neck (13) by a certain length (d) to cover the sealing portion of the aluminum cap (120) and a part of the bottle neck (13).

[0083] The extension (131b) may be formed along the entire circumferential direction at the bottom of the cap cover (130), and in some cases, may be formed to partially protrude downward at regular angle intervals. The downwardly protruding extension (131b) is positioned to be in close contact with the side wall (121) of the aluminum cap (120) when the cap cover (130) is placed over the aluminum cap (120) and extends downward.

[0084] The extension section (131b) completely shields the sealing portion of the aluminum cap (120) from the outside, protecting the sealing structure from external contamination, contact with foreign substances, and physical impact. Additionally, the extension section (131b) forms a double support structure in addition to the lever point when the user presses the cap cover (130) to separate the cap assembly (100) from the vial (10), thereby improving opening stability. That is, when the user presses the side of the cap cover (130) with a finger, the point where the extension section (131b) contacts the bottle neck (13) functions as a secondary lever point in addition to the primary lever point of the lower connecting section (131a) that contacts the bottle opening (11). Since the two lever points are spaced apart vertically, a moment dispersion effect occurs, and as a result, even if the user applies the same pressure, a larger opening moment can be generated.

[0085] In addition, the structure in which the extension section (131b) wraps around the bottleneck (13) suppresses the phenomenon of the cap cover (130) sliding laterally during the pressurization process, thereby allowing the pressurizing force applied by the user to the cap cover (130) to be efficiently transmitted in the opening direction.

[0087] The process of opening a vial (10) using the cap assembly (100) of the present invention having such a configuration is explained with reference to FIGS. 2 to 5.

[0088] The cap assembly (100) of the present invention seals a vial (10) as shown in FIGS. 2 and FIGS. 3. In the cap assembly (100), a rubber cap (110) is pressed into the bottle opening (11), an aluminum cap (120) is clamped to surround the rubber cap (110), and a cup-shaped cap cover (130) is attached to the top of the vial (10) to surround the outside of the aluminum cap (120).

[0089] A liquid medicine (A) is contained inside the vial (10), and a solid medicine (B) is contained inside the cap cover (130). In some cases, the inside of the cap cover (130) is kept empty.

[0090] When a user wants to open the cap assembly (100), the user grasps the body of the vial (10) with one hand (F1) as shown in FIG. 5, and grasps the outside of the cover body (131) of the cap cover (130) with the other hand. Since the height (h3) of the cover body (131) is at least 1.5 times the height (h1) of the protruding column (123) of the aluminum cap (120), the user can position their fingers at a sufficient height contact area.

[0091] The user applies pressure with their hand (F2) from the side of the cap cover (130) in the direction in which the cap cover (130) is removed. At this time, since the lower connecting portion (131a) is connected to the sealing portion of the aluminum cap (120), the lower connecting portion (131a) in the opposite direction to the direction in which the user applies pressure with their finger begins to function as a lever point.

[0092] The lever point distance (R2) is the horizontal distance from the outer wall surface of the cap cover (130) that the user presses with their thumb to the lower connecting end (131a), and corresponds to the outer diameter of the bottle opening (11).

[0093] According to the lever principle, the greater the distance from the point of application, the greater the opening moment generated with the same pressure, so the user can open the cap assembly (100) with less force than when pressing the conventional protrusion (23a) as shown in FIG. 1.

[0094] When the opening moment generated by the user's pressure exceeds the sealing force of the sealing portion of the aluminum cap (120), the cap cover (130) begins to rotate using the lower connecting portion (131a) as the lever point. During this process, the shear force concentrated at the lower clamping portion of the side wall (121) of the aluminum cap (120) plastically deforms the aluminum material, causing the clamping structure to break.

[0095] As the cap cover (130) rotates upward, the aluminum cap (120) connected to the cap cover (130) and the lower connecting member (131a) rotates together, and the side wall (121) of the aluminum cap (120) and the press-fit projection (111) of the rubber cap (110) are separated integrally from the bottle opening (11). As a result, the bottle opening (11) is fully opened, allowing the user to take the liquid medicine (A) inside the vial (10).

[0096] After the cap assembly (100) is separated from the vial (10), the user can open the upper cover (135) using the gripping projection (135b) and take out the solid medicine (B) stored in the medicine storage space (132) inside the cap cover (130) and take it together with the liquid medicine (A).

[0098] The vial bottle cap assembly according to the present invention combines a cup-shaped cap cover with the upper part of an aluminum cap, and when a user's finger force is applied to the cap cover, the distance of the lever point of application can be secured to be significantly larger than when pressing the protrusion of a conventional aluminum cap, so that even women, the elderly, and children with weak grip strength can easily open the vial bottle with minimal force by simply pressing the side of the cap cover with their fingers without a separate opener.

[0099] In addition, the cap assembly of the present invention is formed such that the height of the cap cover is higher than the height of the protruding column, so that the effect of expanding the distance of the lever point of application and the increase in the lever moment due to the increase in the pressure height act in combination, thereby further reducing the force required by the user when opening the vial bottle.

[0100] In addition, since the cap assembly of the present invention is provided with a drug storage space inside the cap cover to store solid drugs, the liquid drug inside the vial and the solid drug inside the cap cover can be packaged together in a single package and easily carried, thereby significantly improving the convenience for users who take two types of drugs simultaneously, such as effervescent vitamins.

[0102] The embodiments of the vial cap assembly of the present invention described above are merely illustrative, and those skilled in the art will readily understand that various modifications and equivalent alternative embodiments are possible therefrom. Therefore, it will be well understood that the present invention is not limited only to the forms mentioned in the detailed description above. Accordingly, the true technical scope of protection of the present invention should be determined by the technical spirit of the appended claims. Furthermore, the present invention should be understood to include all modifications, equivalents, and substitutions within the spirit and scope of the present invention as defined by the appended claims.
