Description

Technical Field

[0001] This invention relates to the field of beverage container technology, and in particular to a bottle cap and a bottle. Background Technology

[0002] Various bottle caps exist in related technologies to separate the solute and solvent within the bottle, allowing them to be mixed only when needed for consumption. However, these caps typically utilize threads on the bottle body or intermediate components to facilitate relative movement between the scraper and the sealing film. To ensure separation between the scraper and the sealing film during storage, a tear-away retaining ring is required on the outer circumference of the cap, corresponding to the thread. This ring restricts the cap's movement, preventing accidental contact between the scraper and the sealing film, which could damage it. However, tearing the retaining ring increases the difficulty of using the cap. Furthermore, removing the ring generates waste that separates from the cap and bottle body, making disposal difficult and prone to accidental littering, thus polluting the environment. Therefore, it is necessary to research and solve this problem. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a bottle cap that enables the film scraping operation of the film scraping component through the cooperation of a guide groove and a guide post.

[0004] The present invention proposes a bottle having the above-mentioned cap.

[0005] The present invention also proposes another bottle having the above-mentioned cap.

[0006] A bottle cap according to a first aspect of the present invention comprises:

[0007] A hopper with a defined axial direction includes a first body and a sealing membrane. The first body is provided with a receiving groove, which has a bottom and an opening arranged sequentially along the axial direction of the hopper. The sealing membrane is connected to the first body and closes the opening. A guide groove is provided on the circumferential outer surface of the first body. The guide groove includes a first channel and a second channel that are interconnected. The first channel and the second channel are arranged sequentially along the circumferential direction of the first body. The first channel extends obliquely from the opening toward the bottom, and the second channel extends along the circumferential direction of the first body.

[0008] A film cutting component includes a second body, a first cutter, and a guide post. The film cutting component has a first hole penetrating the second body. The first cutter and the guide post are both connected to the second body and located in the first hole, and are oriented towards the groove opening along the bottom of the groove. The guide post and the first cutter are arranged sequentially. The guide post is slidably connected to the first body and inserted into the guide groove.

[0009] The bottle cap according to an embodiment of the present invention has at least the following beneficial effects: When the guide post moves in the first channel, the film-cutting member moves axially along the hopper under the guidance of the first channel, causing the first cutter to gradually approach the sealing film. When the guide post moves to a set position in the first channel, the first cutter contacts the sealing film and cuts it as it moves. When the guide post moves to the second channel, the first cutter moves circumferentially along the hopper, thereby continuously cutting the sealing film until it is cut to the point of hanging down, allowing the material in the receiving trough to fall out from the opening of the receiving trough. Compared with the related art, which uses the screw-in direction of the bottle cap to screw the cap in first along the thread and then screw it out along the thread to make the peeling member move relative to the sealing film, the bottle cap of the present invention does not need to be provided with a limiting ring on the bottle body, thereby facilitating the peeling and opening operation for the drinker and reducing the possibility of the limiting ring polluting the environment.

The partition plate is connected to the inner surface of the second cover and closes the second hole. The partition plate is provided with a circumferentially extending knife groove. The knife groove is located on the side of the partition plate facing the first cover and is recessed in the direction away from the first cover. The first cover further includes a second cutter. The second cutter has a connecting end and a cutting edge. The connecting end is connected to the bottom of the groove, and the cutting edge extends in the direction towards the partition plate and is at least partially located in the knife groove.

[0017] According to some embodiments of the present invention, the isolation plate includes a connecting part and a knife-concealing part that are connected to each other. The connecting part is connected to the inner surface of the second cover, and the knife-concealing groove is disposed in the knife-concealing part. Along the direction away from the first cover, the blade end protrudes from the end face of the connecting part on the side away from the first cover.

[0060] The bottle cap and bottle of the present invention are described below with reference to the accompanying drawings.

[0061] Reference Figures 1 to 8 According to a first aspect of the present invention, a bottle cap 100 includes a hopper 300 and a film cutting component 400. The hopper 300 includes a first body 310 and a sealing film 340. The first body 310 is provided with a receiving groove 320 for storing solute. The receiving groove 320 has a bottom 321 and an opening 322 sequentially arranged along the axial direction of the hopper 300. The sealing film 340 is connected to the first body 310 and closes the opening 322, thereby sealing the solute within the receiving groove 320 and preventing direct contact between the solute and the solution. A guide groove 330 is provided on the circumferential outer surface of the first body 310. The guide groove 330 includes a first channel 331 and a second channel 332 that are interconnected. The first channel 331 and the second channel 332 are sequentially arranged along the circumferential direction of the first body 310. The first channel 331 extends obliquely from the opening 322 toward the bottom 321, and the second channel 332 extends along the circumferential direction of the first body 310.

[0062] The film cutting component 400 includes a second body 410, a first cutter 440, and a guide post 430. The film cutting component 400 has a first hole 420 penetrating through the second body 410. The first cutter 440 and the guide post 430 are both connected to the second body 410 and located within the first hole 420, and are positioned along the groove bottom 321 towards the groove opening 322. The guide post 430 and the first cutter 440 are arranged sequentially. The guide post 430 is slidably connected to the first body 310 and inserted into the guide groove 330. When the guide post 430 moves within the first channel 331, the film cutting component 400 moves axially along the hopper 300 under the guidance of the first channel 331, causing the first cutter 440 to gradually approach the sealing film 340. When the guide post 430 moves to a set position within the first channel 331, the first cutter 440 contacts the sealing film 340 and cuts the sealing film 340 as it moves. When the guide post 430 moves to the second channel 332, the first cutter 440 moves circumferentially along the hopper 300, thereby continuously cutting the sealing film 340 until the sealing film 340 is cut to the point of hanging down, so that the material in the receiving trough 320 can fall out from the opening 322 of the receiving trough 320.

[0063] It should be noted that since the hopper and the bottle body, and the hopper and the film cutting part rotate relative to each other, the axial direction of the hopper is the extension direction of the axis of rotation when the hopper rotates.

[0064] In this embodiment of the invention, the bottle cap 100 guides the movement of the film-cutting member 400 through the cooperation of the guide groove 330 and the guide post 430. The movement of the film-cutting member 400 is not directly related to the threaded engagement position of the bottle cap 100 and the bottle body 610. When the bottle cap 100 seals the bottle opening 630 through the threaded connection, it is sufficient to tighten the bottle cap 100 and the bottle body 610. Compared with the related technology, which uses the screw-in direction of the bottle cap 100 to make the bottle cap 100 first screw in along the thread and then screw out along the thread to make the peeling member move relative to the sealing film 340, the bottle cap 100 of the present invention does not need to be provided with a limiting ring on the bottle body 610, thereby facilitating the peeling and opening operation for the drinker and reducing the possibility of the limiting ring polluting the environment.

[0065] The number of receiving grooves 320 and guide pillars 430 is not limited; they can be set in a one-to-one correspondence. Multiple pairs of receiving grooves 320 and guide pillars can improve the stability of the relative movement between the film cutting component 400 and the hopper 300. The number of first cutters 440 is not limited. The setting of multiple first cutters 440 allows multiple cutters to cut the sealing film 340 simultaneously. Compared with cutting by a single first cutter 440, the minimum relative movement distance required between the film cutting component 400 and the hopper 300 can be reduced to achieve the film cutting operation, thereby reducing the length of the second channel 332.

[0066] Furthermore, the first channel 331 and the second channel 332 are connected by an arc surface to achieve a smooth transition, thereby making the movement of the guide post 430 from the first channel 331 to the second channel 332 smooth and reducing the chance of the guide post 430 getting stuck or jammed. Since the guide post 430 slides into the receiving groove 320 by utilizing the deformation of the cutting part 400 during assembly, in order to reduce the deformation of the cutting part 400 during assembly and reduce the assembly difficulty, the outer surface of the hopper 300 is also provided with an axially extending easy-install groove 370. The easy-install groove 370 is connected to the first channel 331. The easy-install groove 370 reduces the deformation that occurs when the guide post 430 abuts against the outer surface of the hopper 300, making it easier for the guide post 430 to slide into the guide groove 330.

[0067] Specifically, the bottle cap 100 and the bottle body 610 can be connected by a threaded connection between the first cap 200 and the bottle body 610, thereby tightening the bottle cap 100 onto the bottle body 610 to seal the opening of the bottle body 610. The first cap 200 is provided with a first groove 210, and the hopper 300 can be fixedly connected to the first cap 200 by adhesive or snap-fit. The hopper 300 is located within the first groove 210, and the rotation of the first cap 200 drives the rotation of the hopper 300, thereby achieving relative movement between the hopper 300 and the film cutting member 400.

[0068] Furthermore, refer to Figure 1 Figure 3 and Figure 6 Along the circumference of the first body 310, one of the outer surface of the hopper 300 and the inner surface of the first cover 200 is provided with an annular boss 350, and the other is provided with an annular groove 220. The annular boss 350 is embedded in the annular groove 220. Through the snap-fit ​​engagement of the annular boss 350 and the annular groove 220, the relative axial movement between the hopper 300 and the first cover 200 can be restricted. Along the axial direction of the hopper 300, one of the inner surface of the first cover 200 and the outer surface of the hopper 300 is provided with a limiting boss 360, and the other is provided with a first limiting groove 230. The limiting boss 360 is embedded in the first limiting groove 230. The engagement between the limiting boss 360 and the first limiting groove 230 restricts the relative rotation of the hopper 300 and the first cover 200. This, together with the annular boss 350 and the annular groove 220, secures the hopper 300 and the first cover 200, improving the connection stability and eliminating the need for adhesive bonding. Furthermore, if the first cover 200 or the hopper 300 is defective during manufacturing, the defective part can be replaced, reducing the cost increase associated with defective products.

[0069] The bottle cap 100 can also be directly threaded to the bottle body 610 via the hopper 300. In this case, the hopper 300 has a second connecting part connected to the first main body 310. The structure of the second connecting part is the same as that of the first cap 200. The hopper 300 can be regarded as the first cap 200 and the first main body 310 being formed as an integral structure. By applying force to the hopper 300, the hopper 300 can be rotated relative to the bottle body 610, thereby tightening and loosening the bottle cap 100.

[0070] When the first cutter 440 cuts the film, because it first moves towards the bottom 321 of the receiving tank 320 to pierce the film before cutting the sealing film 340 along the circumference of the hopper 300, there is a certain probability that the sealing film 340 will tilt upwards towards the bottom 321 of the receiving tank 320 instead of drooping downwards in the direction of material release, thus affecting the descent of the solute in the receiving tank 320. To solve the above problem, an embodiment of the present invention also provides an improvement. (Refer to...) Figure 5 and Figure 6 The guide groove 330 also includes a third channel 333, which is connected to the second channel 332. The first channel 331, the second channel 332 and the third channel 333 are arranged sequentially along the circumference of the first body 310. The third channel 333 extends obliquely along the direction of the first cutter 440 away from the bottom 321 of the receiving groove 320. By setting the third channel 333, after the first cutter 440 performs a flat cut on the sealing film 340, the guide post 430 slides from the second channel 332 to the third channel 333. At this time, the first cutter 440 follows the movement of the guide post 430 and moves in a direction away from the bottom 321 of the receiving groove 320. The first cutter 440 applies a force to the sealing film 340 in a direction away from the bottom 321 of the receiving groove 320, thereby performing a film pressing operation on the sealing film 340 and pulling the sealing film 340 in a direction away from the bottom 321 of the receiving groove 320, increasing the probability that the sealing film 340 will droop in the direction of material release and improving the success rate of the material falling correctly.

[0071] It is understandable that the second channel 332 and the third channel 333 can also be connected by an arc surface to achieve a smooth transition, so that the guide post 430 moves smoothly from the second channel 332 to the third channel 333, reducing the chance of the guide post 430 getting stuck or jammed.

[0072] As a further improvement to the above scheme, referring to Figure 7 and Figure 8The first cutter 440 includes a third body 441, a first cutter 442, and a second cutter 443. The third body 441 is connected to the second body 410, and both the first cutter 442 and the second cutter 443 are connected to the third body 441. In the circumferential direction of the first body 310, both the first cutter 442 and the second cutter 443 extend from the first channel 331 to the second channel 332. The extension length of the first cutter 442 is greater than the extension length of the second cutter 443, and they extend along the channel bottom 321 towards the channel opening 322. The first cutter 442 and the second cutter 443 are arranged sequentially. During the movement of the guide post 430 from the first channel 331 to the second channel 332, the first cutter 442 first contacts the sealing membrane 340 to pierce and cut the membrane. When the guide post 430 moves to the second channel 332, the first cutter 442 moves to the side of the sealing membrane 340 near the bottom 321 of the receiving groove 320. At this time, the second cutter 443 contacts the sealing membrane 340 and performs a flat cut. When the guide post 430 moves to the third channel 333, the first cutter 442 moves in a direction away from the bottom 321 of the receiving groove 320. At this time, the bottom surface of the first cutter 442 contacts the sealing membrane 340 and performs a pressing operation. Compared with using the friction of the blade of the first cutter 440 to drive the sealing membrane 340, pressing the sealing membrane 340 with the bottom surface of the first cutter 442 increases the base area of ​​the end face of the first cutter 442 and the sealing membrane 340 facing the bottom 321 of the receiving groove 320, thereby further increasing the probability of the sealing membrane 340 drooping in the direction of material release, and thus increasing the success rate of the material falling correctly.

[0073] The present invention also provides a first aspect embodiment of a bottle 600, referring to Figure 1 and Figure 2 The bottle 600 includes the cap 100 and bottle body 610 described in the first aspect embodiment above. The bottle body 610 has a receiving cavity 620 and a bottle mouth 630 communicating with the receiving cavity 620. The cap 100 seals the bottle mouth 630, and the cap 100 is threadedly connected to the bottle body 610. By applying the cap 100 of the first aspect embodiment of the present invention, the movement of the film cutting member 400 can be guided by the cooperation of the guide groove 330 and the guide post 430, thereby realizing the film cutting operation of the film cutting member 400 on the sealing film 340. Compared with the related art, which uses the screw-in direction of the cap 100 to make the cap 100 first screw in along the thread and then screw out along the thread to make the peeling member move relative to the sealing film 340, there is no need to set a limiting ring on the bottle body 610, thereby facilitating the peeling and opening operation for the drinker and reducing the possibility of the limiting ring polluting the environment.

[0074] When the drinker applies force to unscrew the bottle cap 100 from the bottle body 610, causing the hopper 300 and the film-cutting member 400 to rotate relative to each other, friction is generated due to the contact between the guide post 430 and the wall of the guide groove 330. Therefore, the film-cutting member 400 will rotate along with the hopper 300. It is necessary to increase the rotational speed of the hopper 300 and adjust the inclination angles of the first groove 331 and the third groove 333 to ensure that the guide post 430 moves correctly along the guide groove 330. To solve the above problem, refer to... Figure 1 , Figure 4 and Figure 7 The inner surface of the bottle body 610 is provided with a second limiting block 640, and the outer surface of the film cutting component 400 is provided with limiting teeth 460. The second limiting block 640 abuts against the limiting teeth 460. When the film cutting component 400 rotates together with the hopper 300 due to friction, the second limiting block 640 will contact the limiting teeth 460, thereby restricting the rotation of the film cutting component 400, so that the guide post 430 can move smoothly along the guide groove 330, and improving the film cutting stability of the film cutting component 400.

[0075] Understandably, when the guide post 430 moves to the end of the third channel 333, the guide post 430 will abut against the channel wall of the third channel 333, thereby causing the film cutting part 400 and the material bin 300 to rotate together. At this time, if the second limiting block 640 continues to abut against the limiting tooth 460, the rotation of the material bin 300 will be restricted, and the bottle cap 100 will have difficulty continuing to move along the thread of the bottle body 610, making it difficult to detach from the bottle body 610. As the bottle cap 100 gradually moves away from the bottle body 610 along the axial direction during the unscrewing process, by controlling the axial positions of the limiting tooth 460, the second limiting block 640, the guide post 430, and the guide groove 330, the limiting tooth 460 can rise with the overall movement of the bottle cap 100 to disengage from the second limiting block 640 when the guide post 430 reaches the end of the third groove 333. This allows the bottle cap 100 to smoothly unscrew from the bottle body 610 along the thread.

[0076] Or, further, refer to Figure 1 , Figure 4 and Figure 7In the circumferential direction of the cutting member 400, the limiting tooth 460 extends obliquely relative to the outer surface of the cutting member 400 along the direction from the second channel 332 to the first channel 331, making it easier for the limiting tooth 460 to deform when it abuts against the second limiting block 640. The cross-sectional area of ​​the second limiting block 640 gradually decreases along the direction close to the cutting member 400, so that both sides of the second limiting block 640 in the circumferential direction of the first body 310 are inclined surfaces to guide the deformation of the limiting tooth 460. When the drinker unscrews the bottle cap 100 from the bottle body 610, when the limiting tooth 460 abuts against the second limiting block 640, it can move and deform along the guide inclined surface, thereby passing over the second limiting block 640. In particular, due to the influence of the extension direction of the limiting tooth 460, the drinker needs to apply a large force to the bottle cap 100 for the limiting tooth 460 to deform and cross the second limiting block 640. Therefore, the action of the limiting tooth 460 deforming and crossing the second limiting block 640 will occur after the guide post 430 moves to the end of the third channel 333, and will not affect the correct movement of the guide post 430 in the guide groove 330.

[0077] When the user unscrews the bottle cap 100 from the bottle body 610 and drives the hopper 300 to rotate relative to the film cutting member 400, since the limiting tooth 460 extends obliquely relative to the outer surface of the film cutting member 400 along the direction from the second channel 332 to the first channel 331, when the film cutting member 400 rotates with the hopper 300 due to friction, the second limiting block 640 will abut against the top end of the limiting tooth 460, thereby restricting the rotation of the film cutting member 400, so that the guide post 430 can move smoothly along the guide groove 330, improving the film cutting stability of the film cutting member 400. When the drinker wants to reseal the bottle cap 100, the bottle cap 100 is rotated in the reverse direction so that the bottle cap 100 is tightened to the bottle body 610 by the threads. At this time, since the holding force between the second limiting block 640 and the limiting tooth 460 is along the extension direction of the limiting tooth 460, the limiting tooth 460 can deform under a small driving force, so that the bottle cap 100 can be tightened back to the bottle body 610 through the second limiting block 640.

[0078] Alternatively, as another improvement, the guide groove 330 also includes a fifth channel, which is connected to the third channel 333. The fifth channel extends circumferentially along the first body 310, and the first channel 331, the second channel 332, the third channel 333 and the fifth channel are arranged sequentially along the circumferential direction of the first body 310. This allows the guide post 430 to continue moving in the fifth channel after it reaches the end of the third channel 333. The film cutting member 400 continues to rotate with the guide post 430, but the relative position of the film cutting member 400 and the hopper 300 in the axial direction remains unchanged until it finally follows the hopper 300 and detaches from the bottle body 610.

[0079] In the above solution, a second limiting block 640 is provided on the inner surface of the bottle body 610, which cooperates with the limiting tooth 460 to restrict the unidirectional rotation of the film cutting part 400. However, setting the second limiting block 640 on the bottle body 610 requires process adjustments during the production of the bottle body 610. When the structure of the bottle cap 100 changes, the bottle body 610 may also need to change accordingly. However, the production of the bottle body 610 and the bottle cap 100 is usually separate, which brings inconvenience to production and research and development.

[0080] To address the aforementioned problems, a second aspect of the present invention also provides a bottle cap 100, as shown below. Figures 9 to 16 In addition to the first cap 200, the bottle cap 100 also includes a second cap 500. The second cap 500 includes a fourth body 510 and a second hole 520 penetrating the fourth body 510. The inner surface of the fourth body 510 is provided with an internal thread 530 for threaded connection with the bottle body 610. The second cap 500 is rotatably connected to the inner surface of the first cap 200. Through the rotatable connection between the second cap 500 and the first cap 200, the rotation of the first cap 200 in place can drive the material hopper 300 to move, thereby realizing the relative movement between the material hopper 300 and the film cutting component 400. The threaded connection between the second cap 500 and the bottle body 610 enables the overall threaded connection between the cap 100 and the bottle body 610. Furthermore, the size of the internal thread 530 of the second cap 500 matches most common bottle bodies 610, allowing for threaded connection with most common bottle bodies 610. This minimizes restrictions on the selection of the bottle body 610. Moreover, when structural modifications are required, only the second cap 500 needs to be modified. All the mutually cooperating structures are set on the entire cap 100, reducing the cost of structural changes.

[0081] Furthermore, in order to restrict the rotation of the cutting element 400, refer to Figure 9 , Figure 12 and Figure 16 The film cutting component 400 also includes a first limiting block 450, which is connected to the circumferential outer surface of the second main body 410. The inner surface of the second cover 500 is also provided with a second limiting groove 570 extending axially along the material hopper 300. The first limiting block 450 is inserted into the second limiting groove 570. By the second limiting groove 570 resisting the first limiting block 450, the rotation of the film cutting component 400 relative to the second cover 500 can be restricted, so that when the guide post 430 moves in the guide groove 330, it will not rotate with the material hopper 300. The relative rotation between the material hopper 300 and the film cutting component 400 is achieved by the rotation of the material hopper 300, and the relative axial movement between the material hopper 300 and the film cutting component 400 is achieved by the film cutting component 400, thereby realizing the film cutting operation of the film cutting component 400 on the sealing film 340.

[0082] As an improvement to the above scheme, refer to Figure 9 , Figure 15 and Figure 16 The second cover 500 also includes a partition plate 540, which extends from the bottom 321 of the groove towards the opening 322. The sealing film 340 and the partition plate 540 are sequentially arranged. The partition plate 540 is connected to the inner surface of the second cover 500 and seals the second hole 520. By providing the partition plate 540, the solution and solute are further isolated, further reducing the possibility of contact between the solution and the container, and increasing the sealing performance for the solute. The partition plate 540 also has a circumferentially extending knife groove 561, which is located on the side of the partition plate 540 facing the first cover 200 and recessed in a direction away from the first cover 200. The first cover 200 also includes a second cutter 240, which has a connecting end 241 and a cutting edge 242. The connecting end 241 is connected to the bottom 321 of the container groove 320, and the cutting edge 242 extends in a direction towards the partition plate 540 and is at least partially located within the knife groove 561. The second cutter 240 rotates along with the first cap 200 and the second cap 500 when they rotate relative to each other, thus achieving the cutting action. The blade tip 242 of the second cutter 240 is located within the concealed groove 561 when the first cap 200 is not rotated, thereby ensuring the integrity of the sealing plate of the bottle 600 in the unopened state. Furthermore, the concealed groove 561 is recessed in the direction away from the first cap 200, allowing the second cutter 240 to cut the portion of the separator 540 circumferentially, excluding the concealed groove 561, thus achieving the cutting of the separator 540.

[0083] Furthermore, to improve the cutting efficiency of the second cutter 240, an embodiment of the present invention also provides an improvement. (Refer to...) Figure 16 The partition plate 540 includes a connecting portion 550 and a concealed blade portion 560 connected to each other. The connecting portion 550 is connected to the inner surface of the second cover 500. A concealed blade groove 561 is provided in the concealed blade portion 560. Along the direction away from the first cover 200, the blade tip 242 protrudes from the end face of the connecting portion 550 on the side away from the first cover 200. By controlling the length of the blade tip 242, so that the blade protrudes from the end face of the connecting portion 550 on the side away from the first cover 200, it can be ensured that when the second cutter 240 cuts the connecting portion 550 of the partition plate 540, it can directly cut through the connecting portion 550, thereby improving the cutting efficiency of the second cutter 240 and reducing the number of times the second cutter 240 cuts the partition plate 540.

[0084] It is understandable that by extending the lengths of the first channel 331, the second channel 332, and the third channel 333 on the circumferential outer surface of the first body 310, it can be ensured that the first cutter 440 completes the cutting of the separator plate 540 by the second cutter 240 simultaneously with the completion of the piercing of the membrane. The specific cutting action of the first cutter 440 on the sealing membrane 340 can be achieved by adjusting the slopes of the first channel 331 and the second channel 332 relative to the second channel 332, and the extension lengths of the first channel 331, the second channel 332, and the third channel 333.

[0085] Understandably, when the guide post 430 moves to the end of the third channel 333 and abuts against the wall of the third channel 333, the film cutting component 400 will drive the second cap 500 to move together due to the abutment between the first limiting block 450 and the wall of the second limiting groove 570, thereby unscrewing the second cap 500 away from the bottle body 610 along the thread of the bottle body 610.

[0086] Furthermore, since the second cutter 240 requires the drinker to apply a certain rotational force to the first cap 200 when cutting the separator 540, and especially at the beginning of the cutting, the force required by the drinker is greater than the force required for subsequent cutting actions. Also, when the protruding post moves within the first channel 331 and the third channel 333, the resistance applied to the guide post 430 is greater than that of the second channel 332 because the first channel 331 and the third channel 333 are inclined. To reduce the force required by the drinker to open the cap 100, an embodiment of the present invention also provides an improvement. (Refer to...) Figure 13 and Figure 14 The guide groove 330 also includes a fourth channel 334, which extends circumferentially along the first body 310 and connects to the first channel 331. The fourth channel 334, the first channel 331, and the second channel 332 are arranged sequentially along the circumferential direction of the first body 310. Alternatively, with a third channel 333 provided, the fourth channel 334 connects to the first channel 331, and the fourth channel 334, the first channel 331, the second channel 332, and the third channel 333 are arranged sequentially along the circumferential direction of the first body 310. By providing the fourth channel 334, the guide post 430 moves circumferentially within the fourth channel 334 before entering the first channel 331, thereby causing the cutting piece 400 to rotate relative to the hopper 300 while maintaining their relative axial position.

[0087] By setting the fourth channel 334, the guide post 430 moves circumferentially along the first body 310 within the fourth channel 334 before entering the first channel 331, causing the film cutting component 400 and the hopper 300 to rotate relative to each other while maintaining their relative axial position. After the second cutter 240 performs a cutting operation on the partition plate 540 for a period of time, the first cutter 440 then performs a cutting operation on the sealing film 340. This disperses the large resistance that the second cutter 240 initially needs to overcome when cutting the partition plate 540, and the large resistance that the guide post 430 needs to overcome along the first channel 331 and the second channel 332, reducing the maximum driving force required to twist the bottle cap 100 and making it easier for the user to twist the bottle cap 100.

[0088] The present invention also provides a bottle 600 according to a second aspect embodiment, including the bottle cap 100 of the second aspect embodiment described above, and a bottle body 610, having a receiving cavity 620 and a bottle mouth 630 communicating with the receiving cavity 620. The bottle cap 100 seals the bottle mouth 630, and the second cap 500 is rotatably connected to the bottle body 610. By applying the bottle cap 100 of the second aspect embodiment of the present invention, the movement of the film cutting member 400 can be guided by the cooperation of the guide groove 330 and the guide post 430, thereby realizing the film cutting operation of the film cutting member 400 on the sealing film 340. Compared with the related art, which uses the screw-in direction of the bottle cap 100 to make the bottle cap 100 first screw in along the thread and then screw out along the thread to make the peeling member move relative to the sealing film 340, there is no need to set a limiting ring on the bottle body 610, thereby facilitating the peeling and opening operation for the drinker and reducing the possibility of the limiting ring polluting the environment. Furthermore, by matching the threads of the second cap 500 with those of most general-purpose bottle bodies 610, the structural requirements of the bottle body 610 are reduced when the cap 100 performs the film-cutting function, thereby improving the applicability of the cap 100.

[0089] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
