Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bottles, in particular to a bottle opening and closing structure and a water bottle. BACKGROUND

[0002] Most of the existing water bottles on the market are combined by threaded connection or hinge connection of the bottle body and the bottle cap. The structure is too simple, does not meet the market product diversity characteristics, and has a series of disadvantages.

[0003] The threaded connection is usually rotated on the threaded tooth structure of the bottle cap on the bottle body to open and close the water bottle in a split type. This method has many disadvantages. First, during the rotation process, if the user's hand is too strong or too biased, the screw thread will be worn and the screw thread will not be able to engage, resulting in a silk phenomenon. If the hand strength is not enough, the sealing of the bottle water bottle cannot be guaranteed, which is extremely inconvenient to use. Second, the operation method of rotation is too tedious and time-consuming for the user. Third, if there are stains on the screw thread, it is extremely inconvenient to clean. Fourth, when opening the bottle mouth to fill water, the bottle cap needs to be separated from the bottle body, i.e. the bottle cap is placed at one end, otherwise it cannot be completed.

[0004] The hinge connection is usually opened and closed by the hinge structure of the bottle cap and the bottle body in an integrated flip type. This method has a big disadvantage. When the hinge end has stains, the user cannot clean it. When the bottle cap is damaged and the sealing of the bottle water bottle is a problem, the entire water bottle cannot be used. It is not only extremely inconvenient for consumers, but also increases additional expenses. SUMMARY

[0005] The purpose of the present application is to solve the problems in the prior art and provide a bottle opening and closing structure. This opening and closing structure can not only ensure the sealing of the bottle structure, but also has the advantages of split type and integrated type opening and closing structure. To achieve the above purpose, the present application adopts the following technical scheme:

[0006] A bottle opening and closing structure, a buckle assembly and a shaft sleeve assembly, wherein: the buckle assembly includes an opening and closing buckle and a safety buckle respectively arranged on the bottle body and the bottle cap of the bottle; the opening and closing buckle and the safety buckle have a buckle position, at the buckle position, the connection between the bottle cap and the bottle body is opened or closed by the buckle connection of the opening and closing buckle and the safety buckle; the shaft sleeve assembly includes a shaft and a shaft cavity sleeve respectively arranged on the bottle body and the bottle cap; the shaft is inserted into the shaft cavity sleeve, so that the bottle cap can rotate horizontally relative to the bottle body.

[0007] Preferably, the rotating shaft has a first positioning part, the shaft cavity sleeve has a second positioning part matched with the first positioning part, when the rotating shaft rotates to the first positioning part matched with the second positioning part in the shaft cavity sleeve, the opening and closing buckle and the safety buckle are positioned to the buckling position.

[0008] Preferably, the shaft cavity sleeve is provided with a shaft cavity and an arc-shaped track, the arc-shaped track is annularly arranged in the shaft cavity, the arc-shaped track is provided with a falling position step to form the second positioning part, the first positioning part is protruded on the side wall of the rotating shaft, when the rotating shaft is inserted into the shaft cavity sleeve, the rotating shaft is inserted into the shaft cavity, and the first positioning part is slidably arranged in the arc-shaped track, when the rotating shaft rotates, the first positioning part slides along the arc-shaped track and falls into the falling position step to be matched with the second positioning part.

[0009] Preferably, the rotating shaft and the shaft cavity sleeve have only one insertion position, at the insertion position, the rotating shaft can be inserted into or separated from the shaft cavity sleeve.

[0010] Preferably, the shaft cavity sleeve is provided with a limiting plate at the top, the limiting plate is provided with a first position hole matched with the rotating shaft and a second position hole matched with the first positioning part, so that the rotating shaft and the shaft cavity sleeve form the insertion position at the position where the first positioning part and the second position hole are projected.

[0011] Preferably, the arc-shaped track is provided with a rising position step to limit the first positioning part from sliding to the rising position step. Preferably, the water tank is further provided with a dropping port, and the dropping port is provided with a sealing cover.

[0012] Preferably, the opening and closing buckle is fixedly arranged on the bottle body, and the safety buckle is hingedly arranged on the bottle cap to be buckled and connected to the opening and closing buckle by rotating the safety buckle.

[0013] Preferably, the shaft cavity is provided with a drainage channel at the bottom, and the outer diameter of the drainage channel is smaller than the outer diameter of the rotating shaft.

[0014] Preferably, the falling position step is an elastic member, and when the bottle cap and the bottle body are connected by the buckling assembly, the first positioning part and the second positioning part are connected in interference fit.

[0015] A water bottle is also provided, which comprises a bottle cap, a bottle body, and an opening and closing structure of the bottle as described above, the rotating shaft is fixedly arranged on the bottle cap, and the shaft cavity sleeve is fixedly arranged on the bottle body.

[0016] (1) The technical scheme of the present application, when the rotating shaft is inserted into the shaft cavity sleeve, the user can horizontally rotate the bottle cap to the buckling position, and seal and install the bottle through the opening and closing buckle and the safety buckle; if the user needs to open the bottle mouth of the bottle body, the user can first open the connection between the bottle body and the bottle cap through the opening and closing buckle and the safety buckle, then horizontally rotate the bottle cap relative to the bottle body until the bottle mouth is completely opened, and then the bottle cap will always be hung on the bottle body without being separated from the connection, and the integrated connection is continued; the user can also horizontally rotate the bottle cap relative to the bottle body, and then touch the bottle cap to take it off the bottle body for separation. Therefore, by horizontally rotating the bottle cap relative to the bottle body, the bottle cap can be selectively hung on the bottle body for integrated connection, without worrying about the bottle cap separating from the bottle body; the bottle cap can also be selectively separated from the bottle body, which is convenient for the user to clean the bottle cap and the bottle body, and can prevent the bottle cap from being replaced when it is damaged, saving time and effort, and having the advantages of integrated structure and split structure, avoiding the defects brought by them, bringing more diverse products to the market, and being conducive to market competition.

[0017] (2) By setting the first positioning part on the rotating shaft and the second positioning part on the shaft cavity sleeve, when the bottle cap is rotated relative to the bottle body, it only needs to be rotated to the first positioning part and the second positioning part to be connected to each other, so that the safety buckle and the opening and closing buckle can be accurately positioned on the buckling position, which is convenient for the user to quickly close the connection between the bottle cap and the bottle body, and improves the convenience.

[0018] (3) The first positioning part is a structure protruding from the side wall of the rotating shaft, the shaft cavity sleeve is provided with an arc-shaped track slidably connected with the first positioning part, and a landing step is arranged on the arc-shaped track as the second positioning part. Not only does it provide support and sliding track for the rotating shaft and the shaft cavity sleeve, but also simplifies the adaptation structure of the first positioning part and the second positioning part, ensuring that when the first positioning part and the second positioning part are adapted, the opening and closing buckle and the safety buckle have a close enough buckling distance to fall into the buckling position, achieving quick buckling positioning. At the same time, the landing step restricts the rotation of the protruding structure on the side wall of the rotating shaft, achieving the effect of limiting the rotation of the bottle cap.

[0019] (4) By providing an insertion position between the rotating shaft and the shaft cavity sleeve, the bottle cap and the bottle body can be inserted or separated at the insertion position to separate the bottle body and the bottle cap, and the separation of the bottle body and the bottle cap is limited at other positions, so that the bottle cap is not easily taken off the bottle body at will, preventing the bottle cap from being lost.

[0020] (5) The limiting plate has a first position allowing hole matched with the rotating shaft and a second position allowing hole matched with the first positioning part. When the bottle cap is rotated to a certain angle, only the first positioning part and the second position allowing hole need to complete the projection overlap, and the rotating shaft and the shaft cavity sleeve are located in the insertion position. Similarly, when the bottle cap is separated from the bottle body, if the first positioning part on the rotating shaft and the second position allowing hole are not always overlapped, the sidewall on the rotating shaft will always be stuck on the limiting plate and cannot come out, that is, the bottle cap and the bottle body cannot be separated. Similarly, only the first positioning part and the second position allowing hole can be overlapped, the rotating shaft can be inserted into the shaft cavity sleeve, and the bottle cap and the bottle body can be connected and installed, which simplifies the mechanical mechanism of the insertion position.

[0021] (6) A lifting step is arranged on the arc-shaped track to limit the rotation angle of the bottle cap relative to the bottle body, preventing the bottle cap from rotating arbitrarily on the bottle body.

[0022] (7) The safety buckle is provided with a hinged structure to be directly buckled and connected on the opening and closing buckle through the rotation of the safety buckle, which is simple in structure and convenient to assemble.

[0023] (8) In order to prevent water from accumulating in the shaft cavity of the shaft cavity sleeve, a first drainage channel is arranged at the bottom of the shaft cavity to ensure that the water flow is discharged through the drainage channel when water accumulates, keeping the bottle body clean.

[0024] (9) The landing step is a resilient member. When the bottle cap and the bottle body are connected by the buckling assembly, the landing step is retracted and deformed to make the first position allowing part and the second positioning part fit and connect with interference, thereby enhancing the locking effect of the bottle body and the bottle cap. Because the first position allowing part and the second positioning part have interference fit, when the buckling assembly of the bottle cap and the bottle body is opened, the resilient member that is deformed by extrusion can pop the first positioning part out of the landing step, which is convenient for the user to rotate and open the bottle mouth.

[0025] (10) The opening and closing structure can be applied not only to water bottles and milk bottles, but also to other cup products. BRIEF DESCRIPTION OF DRAWINGS

[0045] First embodiment

[0046] Please see Figures 1 to 12 .

[0047] The present embodiment provides an opening and closing structure of a bottle, which comprises a buckle assembly and a rotating shaft 41 sleeve assembly, wherein the buckle assembly comprises an opening and closing buckle 31 arranged on the bottle body 1 and a safety buckle 32 arranged on the bottle cap 2, and the opening and closing buckle 31 and the safety buckle 32 have a clamping position, that is, when the opening and closing buckle 31 corresponds to the safety buckle 32, the opening and closing buckle 31 can be connected with the safety buckle 32; wherein the safety buckle 32 is hinged to the bottle cap 2 of the bottle, and is connected to the opening and closing buckle 31 by hinged rotation of the safety buckle 32, so as to complete the assembly of the bottle cap 2 and the bottle body 1.

[0048] In the embodiment, the rotating shaft 41 sleeve assembly comprises the rotating shaft 41 and the shaft cavity sleeve 42, wherein the rotating shaft 41 is arranged on the bottle cap 2, the shaft cavity sleeve 42 is arranged on the bottle body 1, the rotating shaft 41 of the bottle cap 2 can be accommodated and inserted on the shaft cavity sleeve 42, and the rotating shaft 41 is used as the shaft to rotate around the bottle body 1 horizontally; the bottle cap 2 rotates around the bottle body 1 through the rotating shaft 41, and when the opening and closing buckle 31 corresponds to the safety buckle 32, the safety buckle 32 can be buckled and connected on the opening and closing buckle 31.

[0049] Referring to Figure 2 In the embodiment, the rotating shaft 41 has a first positioning part 411, and the shaft cavity sleeve 42 has a second positioning part matched with the first positioning part 411, wherein the first positioning part 411 is protruded on the side wall of the rotating shaft 41, and the first positioning part 411 has a "rectangular structure". When the bottle cap 2 rotates relative to the bottle body 1, the first positioning part 411 only needs to be rotated to the mutual matching connection with the second positioning part, so that the safety buckle 32 and the opening and closing buckle 31 can be accurately positioned to the buckling position, and the user can quickly close the connection between the bottle cap 2 and the bottle body 1, thereby improving the convenience.

[0050] Referring to Figures 4 to 6 In the embodiment, the shaft cavity sleeve 42 further has a shaft cavity 422 and an arc-shaped track 423, the arc-shaped track 423 is annularly arranged around the shaft cavity 422, the arc-shaped track 423 has a landing step 4231 at the end thereof, the landing step 4231 is used as the second positioning part, the height of the landing step 4231 is less than the height of the arc-shaped track 423, and the shape of the landing step 4231 can be matched with the first positioning part 411 on the rotating shaft 41. When the rotating shaft 41 is accommodated and inserted in the shaft cavity sleeve 42, the rotating shaft 41 is also inserted in the shaft cavity 422, and the first positioning part 411 is slidably arranged on the arc-shaped track 423; when the rotating shaft 41 rotates, the first positioning part 411 can slide along the arc-shaped track 423 with the rotating shaft 41, and after sliding out of the end of the arc-shaped track 423, the first positioning part 411 falls into the landing step 4231; because the height of the landing step 4231 is less than the height of the arc-shaped track 423, the first positioning part 411 is clamped and constrained on the landing step 4231, so that the rotating shaft 41 cannot rotate. At this time, the first positioning part 411 and the second positioning part are matched with each other, and the opening and closing buckle 31 and the safety buckle 32 are also located at the buckling position and correspond to each other. Therefore, when the first positioning part 411 and the second positioning part are matched and connected, the bottle body 1 and the bottle cap 2 are accurately positioned, the user can quickly close the connection between the bottle cap 2 and the bottle body 1, and the convenience is improved.

[0051] In the embodiment, the arc angle of the arc-shaped track 423 is not more than 180 degrees, so as to limit the sliding distance of the first positioning part 411 on the arc-shaped track 423, and ensure that the user can quickly assemble the bottle cap 2 and the bottle body 1.

[0052] In this embodiment, the arc-shaped track 423 can support the first positioning part 411 to slide thereon. If the height of the arc-shaped track is the same as the height of the positioning step 4231, firstly, the bottle cap 2 will collide with the bottle body 1 when rotating; secondly, the first positioning part 411 cannot; therefore, through the setting of the positioning step 4231, the rotation of the bottle cap 2 can also be constrained by the bottle body 1.

[0053] In this embodiment, in order to ensure that the rotating shaft 41 on the bottle cap 2 can be quickly inserted or separated from the shaft cavity sleeve 42 on the bottle body 1 when the bottle is in use, an insertion position is arranged between the rotating shaft 41 and the shaft cavity sleeve 42, and through the insertion position, it can also be ensured that the bottle cap 2 and the bottle body 1 can be inserted or separated at the insertion position to separate the bottle body 1 and the bottle cap 2 in a split type, and the separation of the bottle body 1 and the bottle cap 2 is limited at other positions, and the bottle cap 2 is not easy to be taken off from the bottle body 1 at will, preventing the bottle cap 2 from being lost.

[0054] Referring to Figure 4 and Figure 12 , in this embodiment, a limiting plate 424 is arranged at the top of the shaft cavity sleeve 42, the limiting plate 424 is provided with a first accommodating hole 4241 and a second accommodating hole 4242, the first accommodating hole 4241 is a circular cavity, and the second accommodating hole 4242 is a rectangular cavity, wherein the first accommodating hole 4241 is matched with the rotating shaft 41, and the second accommodating hole 4242 is matched with the first positioning part 411. Therefore, the projection shape formed by the combination of the first accommodating hole 4241 and the second accommodating hole 4242 is the same as the projection shape of the rotating shaft 41 and the first positioning part 411, when the bottle cap 2 rotates relative to the bottle body 1, until the projection shapes of the two are overlapped with each other, an insertion position is formed; the rotating shaft 41 on the bottle cap 2 can be just inserted into the shaft cavity sleeve 42 through the insertion position, the rotating shaft 41 is matched and connected with the shaft cavity 422, and the first positioning part 411 can be supported and slid on the arc-shaped track 423; on the contrary, if the projection shapes of the two are not overlapped with each other, that is, not located at the insertion position, the rotating shaft 41 cannot be inserted into the shaft cavity sleeve 42.

[0055] In this embodiment, the cross-sectional shapes of the first accommodating hole 4241 and the second accommodating hole 4242 are also the same as the cross-sectional shapes of the rotating shaft 41 and the first positioning part 411.

[0056] In this embodiment, when the bottle body 1 and the bottle cap 2 are installed in one body, the matching connection and the limiting plate 424 of the opening and closing buckle 31 and the safety buckle 32 are mutually echoed, and the two ends are mutually matched and fastened to prevent one end of the bottle cap 2 from being raised, which causes the other end of the bottle cap 2 to be disconnected.

[0057] In this embodiment, when the bottle cap 2 rotates relative to the bottle body 1 to Figure 11The rotation angle of the bottle body 1 and the bottle cap 2 is shown in the figure, and the projection shapes of the two will overlap each other; when the bottle cap 2 is rotated relative to the bottle body 1 to the position shown in the figure Figure 10 The rotation angle of the bottle body 1 and the bottle cap 2 is shown in the figure, and the projection shapes of the two will overlap each other; when the bottle cap 2 is rotated relative to the bottle body 1 to the position shown in the figure

[0058] In this embodiment, when the bottle cap 2 is rotated to open the bottle mouth of the bottle body 1, if the two projection shapes are always not overlapped, the first positioning part 411 will always be stopped by the limiting plate 424 in the shaft cavity 422, that is, the bottle cap 2 cannot be removed from the bottle body 1, and the integrated connection of the bottle body 1 and the bottle cap 2 is maintained. Therefore, as long as the bottle cap 2 is not horizontally rotated to the insertion position relative to the bottle body 1 (for example, the rotation angle of the bottle body 1 and the bottle cap 2 is shown in the figure), the bottle cap 2 and the bottle body 1 cannot be disconnected, and even if the bottle cap 2 and the bottle body 1 are both located in the insertion position (see the rotation angle of the bottle body 1 and the bottle cap 2 shown in the figure), if the user does not continue to pick up the bottle cap 2 upward relative to the bottle body 1 at this time, the rotating shaft 41 and the shaft cavity 422 will be mutually clamped, causing the bottle cap 2 and the bottle body 1 to be unable to be disconnected, and still maintaining the integrated connection. In summary, if the bottle cap 2 only performs a rotating action relative to the bottle body 1, the bottle cap 2 and the bottle body 1 can always maintain the integrated connection. Figure 10 The rotation angle of the bottle body 1 and the bottle cap 2 is shown in the figure, and the projection shapes of the two will overlap each other; when the bottle cap 2 is rotated relative to the bottle body 1 to the position shown in the figure Figure 11 The rotation angle of the bottle body 1 and the bottle cap 2 is shown in the figure, and the projection shapes of the two will overlap each other; when the bottle cap 2 is rotated relative to the bottle body 1 to the position shown in the figure

[0059] In this embodiment, when the bottle cap 2 is rotated to open the bottle mouth of the bottle body 1 (see the rotation angle of the bottle body 1 and the bottle cap 2 shown in the figure), the two projection shapes are overlapped, the bottle cap 2 and the bottle body 1 are both located in the insertion position, and as long as the bottle cap 2 is continuously moved upward relative to the bottle body 1, the bottle body 1 and the bottle cap 2 can be disconnected. Therefore, only the upward movement of the bottle cap 2 relative to the bottle body 1 in the insertion position needs to be controlled, and the separation of the bottle body 1 and the bottle cap 2 can be completed. Figure 11 The rotation angle of the bottle body 1 and the bottle cap 2 is shown in the figure, and the projection shapes of the two will overlap each other; when the bottle cap 2 is rotated relative to the bottle body 1 to the position shown in the figure

[0060] In this embodiment, the other side of the arc-shaped track 423 is provided with a lifting step 4232 to limit the sliding of the first positioning part 411 to the direction of the lifting step 4232, limit the rotation angle of the bottle cap 2 relative to the bottle body 1, and prevent the bottle cap 2 from being arbitrarily rotated on the bottle body 1.

[0061] The working principle and use process of the present application are as follows:

[0062] When the bottle mouth of the bottle body 1 needs to be opened, the integrated connection opening mode or the split connection opening mode of the bottle cap 2 and the bottle body 1 can be selected according to the needs.

[0063] When the integrated connection opening mode of the bottle cap 2 and the bottle body 1 is selected, first, the outer cover 5 is detached from the bottle cap 2, and then the safety buckle 32 is controlled by the hand to be detached from the opening and closing buckle 31 through the hinged rotation (seeFigure 7 and Figure 8 );then, the bottle cap 2 is moved upward relative to the bottle body 1 (see Figure 9 ), so that the first positioning part 411 on the rotating shaft 41 of the bottle cap 2 is separated from the falling step 4231, facilitating the subsequent outward sliding of the first positioning part 411 along the arc-shaped track 423; finally, the bottle cap 2 can be continuously controlled to rotate horizontally relative to the bottle body 1, and when the rotating angle of the bottle body 1 and the bottle cap 2 reaches a certain angle as shown in Figure 11 , the bottle cap 2 will always be hung on the bottle body 1 under the clamping action of the rotating shaft 41 and the shaft cavity 422, as long as the bottle cap 2 is not separated from the bottle body 1 by upward movement, and the bottle cap 2 has the advantage of integrated opening and closing structure.

[0064] When the split connection opening mode of the bottle cap 2 and the bottle body 1 is selected, first, the outer cover 5 is detached from the bottle cap 2, and then the safety buckle 32 is controlled to rotate and separate from the opening and closing buckle 31 (see Figure 7 and Figure 8 ) by hand; then, the bottle cap 2 is moved upward relative to the bottle body 1 (see Figure 9 ), so that the first positioning part 411 on the rotating shaft 41 of the bottle cap 2 is separated from the falling step 4231, facilitating the subsequent outward sliding of the first positioning part 411 along the arc-shaped track 423; finally, the bottle cap 2 can be continuously controlled to rotate horizontally relative to the bottle body 1, and when the rotating angle of the bottle body 1 and the bottle cap 2 reaches a certain angle as shown in Figure 11 , the bottle cap 2 needs to be separated from the bottle body 1 by upward movement, and the bottle cap 2 and the bottle body 1 are completed in a split, which also has the advantage of split opening and closing structure.

[0065] When the bottle body 1 needs to be tightly connected with the bottle cap 2, first, the bottle cap 2 and the bottle body 1 are controlled to be located at the insertion position; then, the rotating shaft 41 is inserted into the shaft cavity sleeve 42 and the shaft cavity 422, so that the first positioning part 411 abuts against the arc-shaped track 423; then, the bottle cap 2 is controlled to rotate relative to the bottle body 1 until the first positioning part 411 slides out of the arc-shaped track 423 and falls into the landing step 4231, thereby completing the connection and assembly of the bottle body 1 and the bottle cap 2; finally, the hand controls the safety buckle 32 to be buckled on the opening and closing buckle 31 through the hinged rotation, thereby further enhancing the tightness of the bottle body 1 and the bottle cap 2, so that the first positioning part 411 is completely clamped on the landing step 4231, and the bottle cap 2 is prevented from being shaken up and down on the bottle body 1 due to accidental touch. Therefore, according to the application, the bottle cap 2 can be selectively hung on the bottle body 1 for integrated connection through the horizontal rotation of the bottle cap 2 relative to the bottle body 1, without worrying that the bottle cap 2 will be separated from the bottle body 1; the bottle cap 2 can also be selectively separated from the bottle body 1, which is convenient for the user to clean the bottle cap 2 and the bottle body 1, and can prevent the bottle cap 2 from being replaced when it is damaged, thereby saving time and effort, having the advantages of integrated structure and split structure, avoiding the defects brought by them, bringing more diverse products to the market, and being conducive to market competition.

[0066] In the second embodiment, the opening and closing structure is further improved. In order to prevent water accumulation in the shaft cavity 422 of the shaft cavity sleeve 42, a first drainage channel (not shown in the figure) is arranged at the bottom of the shaft cavity 422, so that when water accumulation occurs, the water flow can be discharged through the drainage channel, thereby keeping the bottle body 1 clean.

[0067] In the third embodiment, the opening and closing structure is further improved. In order to enhance the locking effect of the bottle body 1 and the bottle cap 2, the landing step 4231 is replaced by an elastic member, so that the landing step 4231 has a rebound contraction effect. When the bottle cap 2 and the bottle body 1 are closed and connected through the buckling assembly, the safety buckle 32 is buckled on the opening and closing buckle 31, the bottle cap 2 drives the rotating shaft 41 to abut against the landing step 4231, so that the landing step 4231 is deformed by contraction and extrusion, thereby realizing the interference fit connection of the first displacement part and the second positioning part, completing the enhancement of the locking effect of the bottle body 1 and the bottle cap 2, and improving the sealing performance. Since the first displacement part and the second positioning part have interference extrusion fit, when the buckling assembly of the bottle cap 2 and the bottle body 1 is opened and connected, the deformed elastic member can pop the first positioning part 411 out of the landing step 4231, thereby facilitating the user to rotate and open the bottle mouth.

[0068] In other embodiments, a water bottle is also provided, which comprises the opening and closing structure in the first to third embodiments, wherein the rotating shaft 41 is fixedly arranged on the bottle cap 2, and the shaft cavity sleeve 42 is fixedly arranged on the bottle body 1; when the user opens the bottle mouth to fill water, the bottle cap 2 can be arbitrarily horizontally rotated without worrying about the bottle cap 2 being separated from the bottle body 1, which is very convenient to use; when the user needs to clean the bottle cap 2, the bottle cap 2 can also be separated in a split type, and the bottle cap 2 can be selected according to the needs.
