As used in this specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are intended to include the plural forms

[0040] It should be further understood that the term " / and / " used in this specification of the present invention and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations

[0041] Combined with Figures 1-7 , the embodiments of the present invention provide a ready - to - mix beverage bottle cap, including an inner lid 2, an outer lid 1, and a hopper lid 3

[0042] A storage bin 221 is provided at the bottom of the inner lid 2; the bottom of the outer lid 1 is fitted into the top of the inner lid 2; the top of the storage bin lid 3 penetrates upward through the storage bin 221 and extends to the bottom of the outer lid 1, and is connected and fitted with the bottom of the outer lid 1; the bottom of the storage bin lid 3 abuts against the bottom of the storage bin 221, thereby closing the storage bin 221; wherein, the outer lid 1 can slide up and down relative to the inner lid 2, and the outer lid 1 is used to press down the top of the storage bin lid 3 and drive the storage bin lid 3 to move downward relative to the inner lid 2 when the outer lid 1 slides downward, thereby opening the storage bin 221.

[0043] In this embodiment, materials to be mixed with liquid can be stored in the storage bin 221, and the bottom of the storage bin lid 3 is used to seal the storage bin 221 so that the materials in the storage bin 221 will not spill out. To facilitate opening the storage bin 221, the storage bin lid 3 is arranged to be slidable up and down relative to the inner lid 2. In this way, when it is necessary to open or close the storage bin 221, only the corresponding sliding down or sliding up operation of the storage bin lid 3 needs to be driven. Moreover, the storage bin lid 3 will not fall off and will not affect the consumption of the liquid in the bottle, and the safety is guaranteed; after use, only the storage bin lid 3 needs to be driven to move upward relative to the inner lid 2 until they abut against each other.

[0044] Specifically, to facilitate the up and down sliding operation of the storage bin lid 3, the top of the storage bin lid 3 penetrates upward through the storage bin 221 and extends to the bottom of the outer lid 1. Through the mutual cooperation between the top of the storage bin lid 3 and the bottom of the outer lid 1, when the outer lid 1 slides up, it can move upward relative to the inner lid 2 and the storage bin lid 3, and when it slides down after sliding up, the outer lid 1 can press down the top of the storage bin lid 3, thereby driving the storage bin lid 3 to move downward relative to the inner lid 2, and then opening the storage bin 221. The whole process of opening the storage bin 221 only requires two actions, namely lifting the outer lid 1 and pressing down the outer lid 1, and the storage bin lid 3 can slide down and open. Moreover, the two actions are on the same axis, which is simple and practical. And the embodiment of the present utility model is composed of three components: the inner lid 2, the outer lid 1, and the storage bin lid 3. The production cost of the components is low. In particular, there are no lifters on the inner lid and the outer lid, which is suitable for large-scale low-cost production.

[0045] In one embodiment, the inner lid 2 includes a bottle cap portion 21 and a storage bin body 22. The bottle cap portion 21 is fitted into the bottom of the outer lid 1, and the bottom of the storage bin body 22 is hollowed out to form the storage bin 221; a through hole is provided on the inner lid 2, and the through hole penetrates through the bottle cap portion 21 and the storage bin body 22 from top to bottom in sequence; the top of the storage bin lid 3 extends to the bottom of the outer lid 1 through the through hole.

[0046] In this embodiment, to achieve stable up-and-down sliding of the outer cover 1 relative to the inner cover 2, the top of the inner cover 2 is provided as a bottle cap portion 21. The shape and size of the bottle cap portion 21 are adapted to the bottom of the outer cover 1 and can be completely fitted into the bottom of the outer cover 1. A convex position 211 is provided on the outer side of the bottle cap portion 21, and a groove 11 corresponding to the convex position 211 is provided on the inner side of the bottom of the outer cover 1. The convex position 211 and the groove 11 are fitted and connected in the up-and-down direction. It should be understood that it is also possible to provide a groove 11 on the outer side of the bottle cap portion 21 and a convex position 211 on the inner side of the bottom of the outer cover 1. More specifically, a plurality of convex positions 211 and grooves 11 are provided and are evenly or unevenly distributed in the circumferential direction, which can provide the stability of the up-and-down sliding of the outer cover 1 relative to the inner cover 2. In this embodiment, an uneven distribution is preferably adopted, which has an anti-misoperation effect.

[0047] In this embodiment, the bottom of the inner cover 2 is provided as a bin body 22. The bottom of the bin body 22 is hollowed out to form the bin 221. The space in the bin 221 can be divided by a partition plate 222. On the one hand, it can prevent the deformation of the through-hole forming and play the role of a reinforcing rib; on the other hand, it can also divide into multiple spaces for separating and storing various materials. For example, it is divided into a symmetric first storage space and a second storage space by a partition plate 222.

[0048] In some other embodiments for achieving stable up-and-down sliding of the outer cover 1 relative to the inner cover 2, an uneven structure can also be provided for cooperation between the outer side of the extension portion 12 and the inner side of the counterbore 212. When the outer cover 1 and the inner cover 2 are installed and the outer cover 1 and the inner cover 2 are pressed in and rotated, the uneven structures on the outer side of the extension portion 12 and the inner side of the counterbore 212 can be just fitted together, so as to realize the sliding and fitting connection of the two in the vertical direction.

[0049] In this embodiment, the bottle cap portion 21 and the bin body 22 can be an integral structure or a split assembly structure. The through-hole serves as a sliding channel at the top of the bin cover 3. The through-hole can sequentially penetrate the bottle cap portion 21 and the bin body 22 from top to bottom along the central axis of the inner cover 2, so that the top of the bin cover 3 can penetrate upward from the bottom of the inner cover 2 into the through-hole and extend to the bottom of the outer cover 1, thereby connecting and cooperating with the bottom of the outer cover 1. In this way, by operating the up-and-down sliding of the outer cover 1 relative to the inner cover 2, the bin cover 3 can be driven to move downward. It should be noted that when the outer cover 1 slides upward relative to the inner cover 2, the bin cover 3 is already closed at the bottom of the inner cover 2, so the bin cover 3 will not move upward with the outer cover 1. When the outer cover 1 slides downward relative to the inner cover 2, the top of the bin cover 3 needs to be pressed down through the connection and cooperation between the bottom of the outer cover 1 and the top of the bin cover 3, so as to drive the bin cover 3 to move downward, and then open the bin 221.

[0050] In one embodiment, an extension portion 12 is provided at the bottom of the outer cover 1. The extension portion 12 is inserted into the through-hole and can be connected and cooperated with the top of the bin cover 3. Among them, the shape of the extension portion 12 can be a sleeve shape or a rod shape.

[0051] In this embodiment, to facilitate the connection and cooperation between the bottom of the outer cover 1 and the top of the bin cover 3, an extension portion 12 is provided at the bottom of the outer cover 1. The extension portion 12 is inserted into the through hole from the top of the bottle cap portion 21, and the top of the bin cover 3 is located in the extension portion 12 and is connected and cooperated with the inner wall of the extension portion 12.

[0052] In one embodiment, the bin cover 3 includes a connecting rod 31 and a bottom cover 32. The bottom cover 32 is disposed at the bottom of the bin 221 to close the bin 221. One end of the connecting rod 31 is connected to the bottom cover 32, and the other end of the connecting rod 31 extends through the through hole to the extension portion 12, and the other end of the connecting rod 31 is connected and cooperated with the extension portion 12.

[0053] In this embodiment, the connecting rod 31 and the bottom cover 32 can be integrally provided or assembled separately. One end of the connecting rod 31 is connected to the central position of the top of the bottom cover 32, and the other end of the connecting rod 31 passes through the through hole and extends into the extension portion 12. It should be understood that the connection and cooperation structure can be provided on the outer wall of the other end of the connecting rod 31 and the inner wall of the extension portion 12, so as to realize the up and down sliding operation of the outer cover 1 driving the connecting rod 31. When the connecting rod 31 slides up and down, the bottom cover 32 can also slide up and down accordingly to achieve the purpose of closing or opening the bin 221.

[0054] In one embodiment, the through hole sequentially includes a counterbore 212 and a guide hole 223 from top to bottom. The extension portion 12 is located in the counterbore 212, and the connecting rod 31 passes through the guide hole 223 and extends to the extension portion 12.

[0055] In this embodiment, the through hole is divided into a counterbore 212 and a guide hole 223 with different apertures. The guide hole 223 can be circular and the aperture is smaller than that of the counterbore 212. The connecting rod 31 is guided by the guide hole 223 to ensure that the connecting rod 31 can slide up and down stably along the vertical direction.

[0056] In this embodiment, the connecting rod 31 extends into the counterbore 212 after passing through the guide hole 223, and at the same time, the counterbore 212 is also used for the insertion of the extension portion 12, so that the connecting rod 31 and the extension portion 12 are connected and cooperated in the counterbore 212.

[0057] In one embodiment, the extension portion 12 and the counterbore 212 are of the same and adapted non-circular shapes.

[0058] In this embodiment, the non-circular shape design of the extension portion 12 and the counterbore 212 is also for the relative position of the outer cover 1 and the inner cover 2 to change in the vertical direction while not changing in the horizontal direction.

[0059] In one embodiment, a locking assembly is provided between the through hole and / or the extension portion 12 and the connecting rod 31. The locking assembly is used to lock the connecting rod 31, thereby ensuring that the bottom cover 32 locks the silo 221.

[0060] In this embodiment, the locking assembly is used to lock the connecting rod 31 when the bottom cover 32 closes the silo 221 (here it refers to when not in use), so as to ensure that the bottom cover 32 will not move downward and cause the silo 221 to be accidentally opened, that is, to ensure that the bottom cover 32 can lock the silo 221 and prevent the material from leaking out of the silo 221 in advance.

[0061] In one embodiment, a pressing assembly is provided between the extension portion 12 and the connecting rod 31. The pressing assembly is used to unlock the silo 221 when the outer cover 1 slides upward. The pressing assembly is used to press down the connecting rod 31 and drive the bottom cover 32 to move downward relative to the inner cover 2 when the outer cover 1 slides downward after sliding upward, thereby opening the silo 221.

[0062] In this embodiment, as a connection and cooperation structure between the extension portion 12 and the connecting rod 31, the pressing assembly only needs to operate the outer cover 1 to slide upward to unlock the locking assembly, that is, to unlock the locking force on the connecting rod 31, and then operate the outer cover 1 to slide downward. The pressing assembly can press down the connecting rod 31 and drive the bottom cover 32 to move downward relative to the inner cover 2, thereby opening the silo 221. The whole process only has two actions: lifting the outer cover 1 and pressing down the outer cover 1, and the two actions are on the same axis, which is simple and practical.

[0063] In one embodiment, the pressing assembly may include a first pressing buckle 122 and a second pressing buckle 311 that are in the same horizontal position. The first pressing buckle 122 is disposed in the extension portion 12, and the second pressing buckle 311 is disposed on the connecting rod 31. At least one of the first pressing buckle 122 and the second pressing buckle 311 is an elastic structure; in the state where the silo 221 is not opened, the second pressing buckle 311 is located above the first pressing buckle 122; the outer cover 1 is used to drive the first pressing buckle 122 to move upward when the outer cover 1 slides upward and make the first pressing buckle 122 located above the second pressing buckle 311; the outer cover 1 is used to press down the second pressing buckle 311 through the first pressing buckle 122 when the outer cover 1 slides downward after sliding upward, so as to press down the connecting rod 31.

[0064] In this embodiment, during the up-and-down sliding of the outer cover 1, it is necessary for the first pressing buckle 122 and the second pressing buckle 311 to be able to connect and cooperate with each other. Therefore, the first pressing buckle 122 and the second pressing buckle 311 are set to be in the same position in the horizontal direction. During the upward sliding of the outer cover 1, the outer cover 1 will drive the first pressing buckle 122 to move upward. During the upward movement of the first pressing buckle 122, it will be blocked by the second pressing buckle 311. Therefore, at least one of the first pressing buckle 122 and the second pressing buckle 311 is provided with an elastic structure, so that when the first pressing buckle 122 moves upward past the second pressing buckle 311, it can undergo elastic deformation through mutual extrusion, so that the first pressing buckle 122 can cross over the second pressing buckle 311 and be located above the second pressing buckle 311. At this time, the upward movement of the outer cover 1 is completed. Then, when the outer cover 1 is operated to slide downward, the outer cover 1 will drive the first pressing buckle 122 to move downward and contact the second pressing buckle 311. However, at this time, it is necessary to realize that the first pressing buckle 122 presses down the second pressing buckle 311 instead of crossing over the second pressing buckle 311. Therefore, a blocking structure can be set at the contact position between the bottom of the first pressing buckle 122 and the top of the second pressing buckle 311, so that the two can block each other in the vertically downward direction.

[0065] In one embodiment, a anti-disengagement component is provided between the through hole and / or the extension portion 12 and the connecting rod 31. The anti-disengagement component is used to limit the downward pressing of the connecting rod 31, thereby restricting the downward pressing stroke of the connecting rod 31.

[0066] In this embodiment, the anti-disengagement component is used to prevent the connecting rod 31 from moving downward excessively or falling off during the process of the outer cover 1 sliding downward and pressing down the connecting rod 31, which may affect the drinking experience.

[0067] To more comprehensively reflect the instant-mixing beverage bottle cap of the present application, the following six embodiments of the bottle cap are exemplified in the present application.

[0068] Embodiment 1:

[0069] Combined with Figures 5-7 , in one embodiment, the locking component includes a second locking buckle 313, a first locking buckle 224 and a locking buckle gear 124 in the same horizontal direction. The second locking buckle 313 is arranged on the connecting rod 31, the first locking buckle 224 is arranged in the through hole, and the locking buckle gear 124 is arranged in the extension portion 12; wherein, the first locking buckle 224 and the second locking buckle 313 have a concave-convex locking structure, the first locking buckle 224 is located outside the second locking buckle 313, and the locking buckle gear 124 is located outside the first locking buckle 224 and presses the first locking buckle 224.

[0070] In this embodiment, the connecting rod 31 may be a square rod-shaped structure as a whole. On the opposite sides of the outer wall of the connecting rod 31, there are two pairs of protrusions distributed at intervals up and down, so that two concave second locking buckles 313 are formed at the positions on the outer wall of the connecting rod 31 between the two pairs of protrusions. It should be understood that only one pair of protrusions may be provided, and two concave second locking buckles 313 may also be formed at the positions below the one pair of protrusions on the outer wall of the connecting rod 31. On the inner wall of the through hole (specifically, in the counterbore 212), two opposite first locking buckles 224 are provided. In the state where the material bin 221 is not opened, the two first locking buckles 224 are buckled in the two second locking buckles 313, and at this time, the connecting rod 31 can already be locked. In order to further improve the locking effect on the connecting rod 31, two locking buckle positions 124 are provided on the opposite inner walls of the extension portion 12. By pressing the locking buckle positions 124 against the outer sides of the two first locking buckles 224, the two first locking buckles 224 are prevented from disengaging from the two second locking buckles 313, thereby realizing the locking of the connecting rod 31 and further realizing the locking of the material bin 221.

[0071] In other embodiments, the locking assembly may also only include two second locking buckles 313 and two locking buckle positions 124, and the two locking buckle positions 124 are directly buckled in the two second locking buckles 313 to realize the locking of the connecting rod 31.

[0072] In one embodiment, at least one of the top of the first pressing buckle 122 and the bottom of the second pressing buckle 311 is a bevel surface, and the first pressing buckle 122 can be squeezed upward and cross over the second pressing buckle 311; the bottom of the first pressing buckle 122 and the top of the second pressing buckle 311 are both horizontal end faces or bevel surfaces that block each other in the vertical direction, and the first pressing buckle 122 can press downward on the second pressing buckle 311.

[0073] In this embodiment, during the process of sliding the outer cover 1 upwards, at least one of the top of the first pressing buckle 122 and the bottom of the second pressing buckle 311 is designed as an inclined surface with a certain degree of downward slope. This slope is set so that the first pressing buckle 122 can move upwards and cross over the second pressing buckle 311 when moving upwards through the second pressing buckle 311. At this time, since at least one of the first pressing buckle 122 and the second pressing buckle 311 is an elastic structure, as the outer cover 1 continues to slide upwards, it will drive the first pressing buckle 122 and the second pressing buckle 311 to squeeze each other, and under the action of the inclined surface, the first pressing buckle 122 will move upwards and cross over the second pressing buckle 311. During the process of the outer cover 1 sliding downwards after sliding upwards, the bottom end surface of the first pressing buckle 122 presses the top end surface of the second pressing buckle 311. Here, the bottom end surface of the first pressing buckle 122 and the top end surface of the second pressing buckle 311 are set as horizontal end surfaces or the contact surfaces of the two are appropriately inclined inwards, which can make the two block each other in the vertical direction to improve the stability of their connection and realize pressing down the connecting rod 31, thereby opening the material bin 221.

[0074] In this embodiment, more specifically, a set (i.e., two) of opposite first pressing buckles 122 are provided on the extension portion 12. An avoidance channel through which the second pressing buckle 311 of the connecting rod 31 can pass is provided in the space between the opposite first pressing buckles 122, and at the same time, a space for accommodating the second pressing buckle 311 is provided above the first pressing buckle 122. During installation, the second pressing buckle 311 can pass upwards through the avoidance channel, and after reaching the diagonally upper part of the first pressing buckle 122, it rotates to reach directly above the first pressing buckle 122. Based on this, when opening the material bin 221, the upward sliding of the outer cover 1 drives the first pressing buckle 122 to cross over the second pressing buckle 311 and reach above the second pressing buckle 311. Then, when the outer cover 1 slides downwards, it can drive the first pressing buckle 122 to press down the second pressing buckle 311, driving the bottom cover 32 to move downwards relative to the inner cover 2, thereby opening the material bin 221.

[0075] In one embodiment, the anti - detachment assembly includes a first anti - detachment buckle 123 and a second anti - detachment buckle 312 that are in the same horizontal position. The first anti - detachment buckle 123 is provided on the inner wall of the extension portion 12, and the second anti - detachment buckle 312 is provided on the top of the connecting rod 31; when the material bin 221 is not opened or in the opened state, the second anti - detachment buckle 312 is located above the first anti - detachment buckle 123.

[0076] In this embodiment, two first anti - detachment latches 123 may be provided and are respectively located on the inner walls of opposite sides of the extension part 12. Correspondingly, two second anti - detachment latches 312 may be provided and are respectively located on the opposite sides of the top of the connecting rod 31. More specifically, the tops of the first anti - detachment latches 123 and the bottoms of the second anti - detachment latches 312 are both horizontal end faces or inclined planes that block each other in the vertical direction (for example, the tops of the first anti - detachment latches 123 are inclined downward from the inside to the outside, and the bottoms of the second anti - detachment latches 312 are inclined downward from the inside to the outside, forming an inverted buckling effect). Based on this, during the process of the outer cover 1 sliding down and pressing down the connecting rod 31, through the cooperation of the horizontal end faces of the tops of the first anti - detachment latches 123 and the bottoms of the second anti - detachment latches 312 or the inclined planes that block each other in the vertical direction, it is possible to prevent the connecting rod 31 from moving down excessively or falling off, thus affecting the drinking experience.

[0077] Embodiment Two:

[0078] Combined with Figures 8-10 , the locking assembly of Embodiment Two can be the same as that of Embodiment One. The corresponding structural process in the foregoing Embodiment One can be referred to and will not be elaborated here.

[0079] In an embodiment, a rack is provided on the first pressing latch 122, and the convex teeth of the rack are inclined downward, and a rack is provided on the second pressing latch 311, and the convex teeth of the rack are inclined upward. The first pressing latch 122 and the second pressing latch 311 are meshed and connected.

[0080] In this embodiment, compared with the pressing assembly of Embodiment One, the first pressing latch 122 and the second pressing latch 311 in Embodiment Two are not connected and cooperated through inclined planes and horizontal end faces, but are connected by the meshing of racks. During the process of sliding the outer cover 1 upward, based on the setting of the convex teeth orientations of the racks of the second pressing latch 311 and the first pressing latch 122, the rack of the first pressing latch 122 can be disengaged from the rack of the second pressing latch 311 and move upward; conversely, during the process of sliding the outer cover 1 downward, based on the setting of the convex teeth orientations of the racks of the second pressing latch 311 and the first pressing latch 122, the rack of the first pressing latch 122 can be completely inserted downward into the rack of the second pressing latch 311, thereby pressing down the connecting rod 31 and then opening the material bin 221.

[0081] The anti - detachment assembly of Embodiment Two can be the same as that of Embodiment One. The corresponding structural process in the foregoing Embodiment One can be referred to and will not be elaborated here.

[0082] Embodiment Three:

[0083] Combined with Figure 11 and Figure 12, in one embodiment, the locking assembly includes a second locking buckle 313 and a first locking buckle 224 in the same horizontal direction. The second locking buckle 313 is disposed on the connecting rod 31, and the first locking buckle 224 is disposed in the through hole. Among them, the first locking buckle 224 and the second locking buckle 313 have a concave-convex locking structure.

[0084] In this embodiment, the connecting rod 31 as a whole can also be a square strip structure. Two pairs of protrusions are provided on opposite sides of the outer wall of the connecting rod 31 at intervals in the up and down directions, so that two concave second locking buckles 313 are formed at the positions between the two pairs of protrusions on the outer wall of the connecting rod 31; two opposite first locking buckles 224 are provided on the inner wall of the through hole (which can be on the wall of the guiding hole 223 or at the bottom of the counterbore 212, specifically, on the inner sides of two extension blocks extending upward at the junction of the counterbore 212 and the guiding hole 223). In the state where the bin 221 is not opened, the two first locking buckles 224 are buckled in the two second locking buckles 313, so as to lock the connecting rod 31, and further lock the bin 221.

[0085] In one embodiment, an expansion opening 127 is provided on the extension portion 12. The expansion opening 127 extends downward from the outer wall of the extension portion 12 to the bottom, and the first pressing buckle 122 is disposed at the bottom of the inner wall of the extension portion 12; at least one of the top of the first pressing buckle 122 and the bottom of the second pressing buckle 311 is a slope, and the first pressing buckle 122 can be squeezed upward and cross over the second pressing buckle 311; the bottom of the first pressing buckle 122 and the top of the second pressing buckle 311 are both horizontal end faces or slopes that block each other in the vertical direction, and the first pressing buckle 122 can press downward on the second pressing buckle 311.

[0086] In this embodiment, the shape of the extension portion 12 is cylindrical. Two expansion openings 127 are provided on the extension portion 12. The two expansion openings 127 are opened in the vertical direction, so that the bottom of the extension portion 12 is separated into two opposite parts. Two first pressing buckles 122 are provided and are respectively disposed on the two parts at the bottom of the extension portion 12. Based on this, during the process of sliding the outer cover 1 upward, the slopes of the top of the first pressing buckle 122 and the bottom of the second pressing buckle 311 are inclined and fitted to each other. As the outer cover 1 continues to slide upward, it will drive the first pressing buckle 122 and the second pressing buckle 311 to squeeze each other and cause the two parts at the bottom of the extension portion 12 to expand outward, so that the first pressing buckle 122 crosses over the second pressing buckle 311 upward. During the process of sliding the outer cover 1 upward and then downward, the horizontal end faces of the bottom of the first pressing buckle 122 and the top of the second pressing buckle 311 or the slopes that block each other in the vertical direction block each other, so as to press down the connecting rod 31 and further open the bin 221.

[0087] In one embodiment, compared with the anti - detachment components in the first and second embodiments above, the anti - detachment component in the third embodiment transfers the first anti - detachment buckle 123 provided on the extension portion 12 to the inner wall of the through - hole.

[0088] Specifically, the anti - detachment component in the third embodiment includes a first anti - detachment buckle 123 and a second anti - detachment buckle 312 that are in the same horizontal position. The first anti - detachment buckle 123 is provided on the inner wall of the through - hole, and the second anti - detachment buckle 312 is provided on the top of the connecting rod 31; when the storage bin 221 is not opened or in the opened state, the second anti - detachment buckle 312 is located above the first anti - detachment buckle 123.

[0089] In this embodiment, two first anti - detachment buckles 123 can be provided and are respectively located on opposite sides of the through - hole (specifically, it can be a counterbore 212). Correspondingly, two second anti - detachment buckles 312 can be provided and are respectively located on opposite sides of the top of the connecting rod 31. More specifically, both the top of the first anti - detachment buckle 123 and the bottom of the second anti - detachment buckle 312 are horizontal end faces or inclined planes that block each other in the vertical direction (for example, the top of the first anti - detachment buckle 123 slopes downward from the inside out, and the bottom of the second anti - detachment buckle 312 slopes downward from the inside out, forming an inverted - buckle effect); based on this, during the process of the outer cover 1 sliding down and pressing down the connecting rod 31, through the cooperation of the horizontal end faces of the top of the first anti - detachment buckle 123 and the bottom of the second anti - detachment buckle 312, it is possible to prevent the connecting rod 31 from moving downwards excessively or falling off, thus affecting the drinking experience.

[0090] Embodiment Four:

[0091] Combined with Figures 13-15 , the locking component in the fourth embodiment is similar in principle to that in the third embodiment. The difference is that the shape of the second locking buckle 313 on the connecting rod 31 in the fourth embodiment is an inward - concave annular shape, and the shape of the first locking buckle 224 on the inner wall of the through - hole (specifically, it can be on the inner wall of the guide hole 223) is an outward - convex annular shape, that is, the second locking buckle 313 and the first locking buckle 224 are also locked and matched through a concave - convex structure.

[0092] The pressing component in the fourth embodiment is similar in principle to that in the first embodiment. The difference is that the shape of the second pressing buckle 311 on the connecting rod 31 in the fourth embodiment is an outward - convex annular shape. The bottom of the second pressing buckle 311 transitions upward with an annular inclined plane, and the top surface of the second pressing buckle 311 is an annular horizontal end face.

[0093] The anti - detachment component in the fourth embodiment is similar in principle to that in the third embodiment. The difference is that the shape of the second anti - detachment buckle 312 on the connecting rod 31 in the fourth embodiment is an outward - convex annular shape, and the bottom of the second anti - detachment buckle 312 is an annular horizontal end face.

[0094] Example 5:

[0095] Combined with Figure 16 and Figure 17 , the locking component of Example 5 is similar to that of the above-mentioned First Embodiment in principle. Both are provided with a mutually cooperating concave-convex locking structure between the inner wall of the extension part 12 and the outer wall of the connecting rod 31.

[0096] In Example 5, the pressing component and the anti-detaching component are integrally arranged. Specifically, two opposite vertical openings 128 are formed on the extension part 12. The vertical openings 128 extend upward from the outer wall of the extension part 12 to the top. Two first pressing buckles 122 (here, the first pressing buckles 122 are described as the integration of the pressing component and the anti-detaching component) are arranged at the bottom ends of the two vertical openings 128. The bottoms of the two second pressing buckles 311 are inclined downward from the outside to the inside in the circumferential direction. The tops of the two second pressing buckles 311 are both horizontal end faces or inclined downward in the direction from the outside to the inside in the circumferential direction. Two second anti-detaching buckles 312 are respectively located directly above the two second pressing buckles 311 and form a limiting space. The bottoms of the two second anti-detaching buckles 312 are both horizontal end faces or inclined upward in the direction from the outside to the inside in the circumferential direction. After the outer cover 1 is slid upward, the two first pressing buckles 122 can be limited in the limiting space and cannot be detached, thus realizing the integration of the functions of the pressing component and the anti-detaching component.

[0097] Combined with Figure 18 and Figure 19 , in some other implementation manners of Example 5, the difference lies in that the vertical openings 128 extend downward from the outer wall of the extension part 12 to the bottom, and the two first pressing buckles 122 are arranged at the tops of the two vertical openings 128.

[0098] Combined with Figure 20 and Figure 21 , in some other implementation manners of Example 5, the vertical openings 128 may not be provided, and slits are formed at the connections between the two first pressing buckles 122 and the outer wall of the extension part 12, so that the first pressing buckles 122 have a certain elasticity.

[0099] Example 6:

[0100] Combined with Figure 22 and Figure 23The inner cover 2 includes a bottle cover portion 21 and a silo body 22, the bottle cover portion 21 is engaged with the bottom of the outer cover 1, and the bottom of the silo body 22 is hollowed out to form the silo 221; the top of the inner cover 2 is hollowed out and an extending protrusion 214 is provided upward at the hollowed out portion, the bottom of the outer cover 1 is slidably connected to the extending protrusion 214, and a through hole is provided on the inner cover 2, and the through hole passes through the extending protrusion 214 and the silo body 22 in sequence from top to bottom; the top of the silo cover 3 extends to the bottom of the outer cover 1 through the through hole.

[0101] In this embodiment, different from the above five embodiments, the extension portion 12 of the outer cover 1 includes two extension rods with elastic function (for example, plastic rods, the material itself has a certain elasticity), the lower end surface of the extension rod is a slope, and the bottom of the countersunk hole 212 of the inner cover 2 is provided with a slope corresponding to the slope of the lower end of the extension rod. When the two are squeezed against each other, the two extension rods can be stretched apart, so that the top of the connecting rod 31 can enter the space between the two extension rods through the bottom of the extension rod. In this process, there is no need to open the assembly port 125 at the top of the bottle cap portion 21, and there is no need to use the assembly jig 4 (refer to Figure 24 The squeezing of the two can be achieved by other squeezing tools, wherein the squeezing force is greater than the force of tapping the outer cover 1 under normal circumstances, so tapping the outer cover 1 during use will not cause the outer cover 1 and the silo cover 3 to come off.

[0102] In this embodiment, the shape of the extension protrusion 214 can be a circular sleeve, the inner side of the outer cover 1 is embedded in the outer side of the extension protrusion 214, a sliding bar is set on the inner side of the outer cover 1, and a sliding groove is set on the outer side of the extension protrusion 214, and the outer cover 1 and the extension protrusion 214 are slidably matched up and down through the sliding bar and the sliding groove.

[0103] In the above six embodiments, the positions of the extension part 12 and the connecting rod 31 can be swapped, that is, the extension part 12 is located on the silo cover 3, and the connecting rod 31 is located at the bottom of the outer cover 1. The entire process of locking, unlocking and opening the beverage bottle cover can also be realized.

[0104] The detailed structures of the above six instant beverage bottle cap embodiments are further described below.

[0105] In one embodiment, the first pressing buckle 122 and the second pressing buckle 311 , as well as the first anti-detachment buckle 123 and the second anti-detachment buckle 312 , are arranged at a certain angle with respect to the horizontal direction.

[0106] In this embodiment, the two sets of buckles are arranged at a certain angle to the horizontal direction to facilitate deformation avoidance or mutual blocking.

[0107] In one embodiment, the first pressing buckle 122 is connected to the extending portion 12 via an elastic member 121 .

[0108] In this embodiment, the elastic member 121 can be a spring structure or a plastic member with elastic deformation function. The spring or plastic member is used to make the first push buckle 122 have the ability of elastic deformation, so that the first push buckle 122 can be deformed and move upward over the second push buckle 311 during the process of operating the outer cover 1 to move upward.

[0109] In one embodiment, the top of the outer cover 1 of Embodiments 1 to 5 is provided with an assembly port 125 connected to the extension portion 12, and the assembly port 125 is used for allowing an external assembly jig 4 to be inserted into the extension portion 12 and to open the first push buckle 122 so that the second push buckle 311 on the connecting rod 31 can pass through the extension portion 12 to reach above the first push buckle 122.

[0110] In this embodiment, when the connecting rod 31 is assembled in the through hole and the extension part 12, the second pressing buckle 311 at the top of the connecting rod 31 needs to pass through the first pressing buckle 122 on the inner wall of the extension part 12 and reach the top of the first pressing buckle 122. Obviously, it is impossible to pass directly, so the first pressing buckle 122 is set as an elastic structure. In this way, it is only necessary to squeeze the first pressing buckle 122 outward to create an escape space during assembly, so that the second pressing buckle 311 at the top of the connecting rod 31 can pass.

[0111] Combination Figure 24 Specifically, an assembly port 125 connected to the extension part 12 is provided at the top of the outer cover 1, and an assembly jig 4 for assisting assembly is provided. The bottom shape of the assembly jig 4 is adapted to the inner wall shape of the extension part 12. After the bottom of the assembly jig 4 is inserted from the assembly port 125 into the inner wall of the extension part 12, the first push buckle 122 of the inner wall of the extension part 12 can be squeezed, so that the first push buckle 122 is deformed and stretched by a spring or a plastic part with elastic deformation, and then the top of the connecting rod 31 is operated to pass through the through hole and enter the receiving hole 41 provided at the bottom of the assembly jig 4. The height of the receiving hole 41 in the vertical direction is higher than the height of the first push buckle 122. In this way, the top of the connecting rod 31 is already above the first push buckle 122 after entering the receiving hole 41, and the assembly jig 4 can be pulled out to complete the assembly. Furthermore, after the assembly is completed, the assembly port 125 can be sealed by a mounting plate 126.

[0112] In one embodiment, a theft-proof ring is connected to the bottom of the bottle cap portion 21 via a connecting bridge, the theft-proof ring is fixed to the beverage bottle, and the outer cover 1 and the bottle cap portion 21 are wrapped with a shrink film.

[0113] In this embodiment, the anti-theft ring can only be arranged below the bottle cap part 21 of the inner cap 2 and is connected to the bottle cap part 21 through a connecting bridge. The anti-theft ring is fixed to the beverage bottle mouth. When the outer cap 1 is rotated, the outer cap 1 drives the inner cap 2 to open the bottle cap. At this time, the beverage in the bottle can be drunk without opening the material bin 221.

[0114] More specifically, the outer cap 1 and the inner cap 2 can be fixed through a shrink film. After tearing the shrink film, the outer cap 1 can be lifted and then tapped to open the material bin 221. At this time, the powder in the material bin 221 is mixed with the beverage in the bottle to form an instant blended beverage. The opening of the material bin 221 is controlled in the up and down direction, and the opening of the bottle cap is controlled in the horizontal direction. In actual application, without opening the material bin 221, part of the beverage in the bottle can be drunk first, and then the material bin 221 can be opened to mix the raw materials in the material bin 221 with the beverage in the bottle, so as to obtain beverages with different concentrations and flavors and enhance the experience.

[0115] In one embodiment, a first sealing ring 321 is provided on the peripheral wall of the bottom cover 32, and the first sealing ring 321 is used to cooperate with the bottom of the inner cap 2 to ensure the airtightness of the material bin 221.

[0116] In this embodiment, a circular clamping groove is formed in the peripheral wall of the bottom cover 32, and the first sealing ring 321 is clamped or formed in the circular clamping groove by overmolding or two-color injection molding. When the bottom cover 32 closes the bottom of the inner cap 2, the first sealing ring 321 closely cooperates with the bottom of the inner cap 2, thereby improving the airtightness between the inside and outside of the material bin 221.

[0117] In one embodiment, a second sealing ring 314 is provided on the peripheral wall of the connecting rod 31, and the second sealing ring 314 is used to cooperate with the through hole to ensure the water isolation of the through hole.

[0118] In this embodiment, multiple second sealing rings 314 can be provided and are spaced apart on the connecting rod 31. Specifically, two second sealing rings 314 can be provided, and the connecting rod 31 is slightly pressed against the inner wall of the through hole (here referring to part of the guide hole 223) through the two second sealing rings 314. Among them, the function of the upper second sealing ring 314 is: to isolate the material bin 221 from the outside and maintain airtightness when the material bin 211 is not opened. When the material bin 221 is in the open state, this sealing ring 314 is still in the guide hole 223, which can prevent water from overflowing through the through hole. Among them, the function of the lower second sealing ring 314 is: when the material bin 221 is not opened, in addition to increasing the airtightness of the material bin 221, it can also prevent powder from entering the guide hole 223 and avoid the problem of smooth downward movement of the connecting rod 31 being hindered.

[0119] In one embodiment, a water-sealing protrusion 13 is provided on the bottom of the outer cover 1, and a water-sealing groove 213 is provided on the top of the bottle cap portion 21; the water-sealing protrusion 13 and the water-sealing groove 213 are used for abutting and cooperating with each other when the top of the bottle cap portion 21 is fitted into the bottom of the outer cover 1 to ensure the water isolation property of the through hole.

[0120] In this embodiment, to further prevent beverage water from entering the inside of the bottle cap upward through the through hole, a second water isolation line is provided. When the beverage water permeates upward through the through hole, it can also be blocked between the top of the bottle cap portion 21 and the bottom of the outer cover 1 by the water-sealing protrusion 13 and the water-sealing groove 213 to prevent the beverage water from leaking out of the outer cover 1. Specifically, the water-sealing protrusion 13 is distributed around the outer periphery of the top of the extension portion 12; correspondingly, a water-sealing groove 213 is provided on the top of the bottle cap portion 21, and the water-sealing groove 213 is distributed around the outer periphery of the through hole. Both of them are plastic concave-convex line structures and have the same shape. After they abut against each other, a water isolation line is formed.

[0121] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
