Description

Technical Field

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

[0002] A honey water separator cap is a type of cap that can be closed onto a bottle and allows for the separate storage of honey. Users can easily and quickly prepare honey water by opening the inner opening of the cap. However, existing honey water separator caps rely on gravity to allow the honey to flow naturally into the bottle after the inner opening is opened. Most honey will spontaneously crystallize when left to stand. The resulting crystallized honey has high viscosity and low fluidity, which may cause the crystallized honey to clump together and accumulate inside the cap. This can lead to a large amount of honey not being able to drain or draining too slowly, potentially resulting in honey waste or difficulty in quickly preparing a good-tasting honey water.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0028] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation.

[0030] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0031] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0032] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0033] The present invention will now be described in conjunction with the accompanying drawings and specific embodiments: Combination Figures 1 to 14 In a first aspect, the present invention provides a bottle cap, including a first bottle cap body 1 and a second bottle cap body 2 that are threaded together. The first bottle cap body 1 has a storage cavity 111 and a first opening 112. The storage cavity 111 can be used to store ingredients, and the first opening 112 communicates with the storage cavity 111, allowing the ingredients in the storage cavity 111 to be discharged from the first opening 112.

[0034] Threaded connection is a common sealing method in the bottle cap industry. Threaded connection can seal the connection between the first bottle cap body 1 and the second bottle cap body 2, and it is convenient for users to screw the first bottle cap body 1 out or into the second bottle cap body 2 by twisting. Specifically, users can apply opposite torques to the first bottle cap body 1 and the second bottle cap body 2 to drive the first bottle cap body 1 to rotate and translate relative to the second bottle cap body 2. The translational movement causes the first bottle cap body 1 and the second bottle cap body 2 to separate or come closer together.

[0035] For ease of description, this embodiment defines the direction of the rotation axis of the rotational motion between the first bottle cap 1 and the second bottle cap 2 when the first bottle cap 1 is screwed out or screwed in relative to the second bottle cap 2 as the first direction.

[0036] In some embodiments, the second cap 2 is at least partially fitted onto the outside of the first cap 1. The second cap 2 can be used to close the bottle 4. When the bottle 4 is closed, the second cap 2 has a through channel in the middle that connects the inside of the bottle 4 to the outside. The first cap 1 can be inserted through the through channel and have a sealing effect.

[0037] In one embodiment, by driving the first bottle cap 1 to rotate relative to the second bottle cap 2, the first bottle cap 1 can be completely detached from the second bottle cap 2, allowing the first bottle cap 1 to be removed from the second bottle cap 2; when the threaded structure of the first bottle cap 1 and the second bottle cap 2 is separated, the constraint between the first bottle cap 1 and the second bottle cap 2 is released, and the first bottle cap 1 can continue to rotate relative to the second bottle cap 2 without limitation on the number of rotations. The user can also lift the first bottle cap 1 upwards to separate the first bottle cap 1 from the second bottle cap 2.

[0038] In another embodiment, a limiting component is provided between the first bottle cap body 1 and the second bottle cap body 2. The limiting component is used to limit the distance that the first bottle cap body 1 can move relative to the second bottle cap body 2, so that the first bottle cap body 1 cannot completely detach from the second bottle cap body 2. Exemplarily, the limiting component may include a limiting protrusion provided on the outer wall of the first bottle cap body 1 and a limiting protrusion ring protruding on the inner wall of the second bottle cap body 2. The limiting protrusion ring can prevent the limiting protrusion from passing through, thereby limiting the distance that the first bottle cap body 1 can move relative to the second bottle cap body 2. Furthermore, in an optional embodiment, when the limiting protrusion contacts the limiting protrusion ring, the threaded structure that mates between the first bottle cap body 1 and the second bottle cap body 2 separates, so that the first bottle cap body 1 can continue to rotate relative to the second bottle cap body 2 without limitation on the number of rotations, even when the first bottle cap body 1 and the second bottle cap body 2 are not separated.

[0039] In some embodiments, the second cap body 2 includes an outer cylinder 21 and a bottom cap 22. The outer cylinder 21 is at least partially fitted onto the first cap body 1, and the bottom cap 22 is used to cover the first opening 112. By setting the bottom cap 22 to cover the first opening 112, the ingredients in the storage chamber 111 can be prevented from being discharged from the first opening 112, thereby storing the ingredients for a longer period of time.

[0040] Furthermore, the bottom cover 22 has a first state and a second state: in the first state, the bottom cover 22 closes the first opening 112; in the second state, the bottom cover 22 is detached from the first opening 112. In an optional embodiment, during transportation, storage, etc., the bottom cover 22 is in the first state and the first opening 112 is closed. When the user needs to drink honey water, the first cap body 1 can be screwed on so that the first cap body 1 is screwed off relative to the second cap body 2. At this time, the bottom cover 22 can switch from the first state to the second state, and the first opening 112 is open to allow the ingredients in the storage chamber 111 to be discharged.

[0041] In an optional embodiment, the ingredient is honey. Most honey will spontaneously crystallize when left to stand. Crystallized honey is a typical shear-thinning fluid among non-Newtonian fluids. Shear-thinning fluids are fluids that become thinner and more fluid when subjected to stirring, squeezing, spreading, or other actions. When the first opening 112 is open and facing downwards, the crystallized honey can flow downwards through the first opening 112 due to gravity. However, due to its high viscosity when left to stand, the flow rate is slow. Furthermore, the relatively large friction and adsorption forces between the crystallized honey and the inner wall of the storage cavity 111 will cause a large amount of honey to remain in the storage cavity 111.

[0042] In some embodiments, in order to increase the discharge rate of shear-thinning fluids such as honey stored in the storage chamber 111 and reduce the amount of them accumulating in the storage chamber 111, the bottom cover 22 is fixedly connected to the outer cylinder 21, and a stirring element 24 is provided protruding on the bottom cover 22, with at least a portion of the stirring element 24 located inside the storage chamber 111.

[0043] When the first cap 1 rotates out relative to the second cap 2, the stirring element 24 can rotate with the outer cylinder 21 relative to the inner wall of the storage cavity 111. The stirring element 24 rotating relative to the inner wall of the storage cavity 111 can stir the honey in the storage cavity 111, reducing the viscosity of the honey and increasing its fluidity, so that most of the honey can flow out from the first opening 112 more quickly, which helps to speed up the honey discharge speed and reduce the honey stagnation in the storage cavity 111. Since the honey in the cap is usually quantitatively prepared, reducing the honey stagnation in the storage cavity 111 helps to ensure the taste of the honey water, so that users can quickly obtain honey water with a good taste. In an optional embodiment, when the number of rotations of the first cap 1 relative to the second cap 2 is not limited, the user can rotate the first cap 1 and the second cap 2 multiple times to make the stirring element 24 fully stir the honey in the storage cavity 111.

[0044] Those skilled in the art will understand that the stirring principle of the stirring element 24 can be as follows: There is significant friction and adsorption between the honey and other viscous ingredients and the surface of the component in contact with it, allowing the honey and other ingredients to move with the component; that is, the honey and other ingredients near the component tend to remain stationary relative to the surface of the component. When the stirring element 24 rotates relative to the inner wall of the storage cavity 111, the honey near the stirring element 24 moves relative to the honey near the inner wall of the storage cavity 111, thereby achieving a stirring effect. Therefore, the shape of the stirring element 24 in a cross-section perpendicular to the first direction can be circular or non-circular; as long as the stirring element 24 is located in the storage cavity 111 and has a certain length, a stirring effect can be achieved.

[0045] In one alternative embodiment, the stirring element 24 is arranged along the rotation axis of the first cap body 1 and the second cap body 2, that is, the stirring element 24 is located approximately on the rotation axis of the relative rotation of the two.

[0046] In another alternative embodiment, the stirring element 24 is biased at the rotation axis of the first cap body 1 relative to the second cap body 2.

[0047] In the first embodiment described above, if the honey or other ingredients near the stirring member 24 rotate with the stirring member 24 solely due to friction and adsorption, relative slippage between the honey or other ingredients and the stirring member 24 is more likely to occur, making it difficult to improve the stirring efficiency. Optionally, to improve the stirring efficiency, the stirring member 24 is non-circular in shape in its cross-section perpendicular to the first direction, so that when the stirring member 24 rotates, its sidewalls can push the nearby honey or other ingredients to move. Compared to relying solely on friction and adsorption to move the honey or other ingredients, the stirring efficiency of direct pushing is higher. In an exemplary form, the stirring member 24 is a strip-shaped member extending into the storage cavity 111 from the first opening 112. The cross-sectional shape of the stirring member 24 can be triangular, rectangular, trapezoidal, etc. For example, the cross-sectional shape of the stirring member 24 can be a thin plate with a large width-to-thickness ratio.

[0048] Further optionally, the agitator 24 may be composed of multiple thin plates. For example, the agitator 24 may include at least three radially distributed sub-plates 241, with recesses between adjacent sub-plates 241 for containing honey. The sidewalls of the sub-plates 241 can push the honey within the recesses. By reducing the thickness of the sub-plates 241 in a section perpendicular to the first direction and / or increasing the protruding length of the sub-plates 241, the size of the recesses between adjacent sub-plates 241 can be increased, allowing the sidewalls of the sub-plates 241 to push more honey to further improve agitation efficiency. Exemplarily, in combination... Figure 11 The stirring component 24 has four radially distributed sub-plates 241, meaning the cross-sectional shape of the stirring component 24 can be cross-shaped; combined with Figure 12 The mixing component 24 has three sub-plates 241 that are radially distributed.

[0049] Furthermore, the thickness of each sub-plate 241 near the bottom cover 22 is greater than that away from the bottom cover 22, in order to increase the structural strength of the root of the agitator 24 and reduce the risk of breakage of the agitator 24.

[0050] In the latter embodiment described above, the stirring member 24 rotates around the rotation axis of the first cap body 1 relative to the second cap body 2. That is, the movement trajectory of the stirring member 24 in the storage chamber 111 is a circle around the rotation axis. This allows the stirring member 24 to come into contact with more honey, thus increasing the stirring efficiency. In this case, the cross-section of the stirring member 24 can be circular or non-circular.

[0051] In an optional embodiment, the stirring element 24 is spaced apart from the inner wall of the storage chamber 111 to form a channel for honey to flow between them, so that the honey can flow in the first direction toward the first opening 112.

[0052] In some embodiments, to better drive the honey near the inner wall of the storage cavity 111 to move with the inner wall of the storage cavity 111, a push plate 12 is provided protruding on the inner wall of the storage cavity 111. The push plate 12 is used to push the nearby honey and other ingredients to move during the rotation of the inner wall of the storage cavity 111 relative to the stirring member 24, so that the honey and other ingredients rotate relative to the stirring member 24. By providing the push plate 12, the probability of the honey near the inner wall of the storage cavity 111 sliding relative to the inner wall of the storage cavity 111 can be reduced, thereby improving the stirring efficiency.

[0053] Furthermore, the pusher plate 12 extends along the length of the storage cavity 111, which is also the aforementioned first direction. The pusher plate 12 extending along the length of the storage cavity 111 can push more honey distributed along the length of the storage cavity 111 during rotational motion, improving the stirring effect. In one embodiment, the pusher plate 12 is parallel to the length of the storage cavity 111, that is, the pusher plate 12 can be a vertical plate arranged along the first direction; in another embodiment, the pusher plate 12 is inclined to the length of the storage cavity 111, that is, the pusher plate 12 can be a spiral plate surrounding the inner wall of the storage cavity 111.

[0054] In an optional implementation, combined with Figure 5 The push plate 12 has a spiral section 122, which is spirally arranged along the inner wall of the storage cavity 111. Along the rotation direction when the first cap body 1 is screwed out relative to the second cap body 2, the plate surface of the spiral section 122 inclined towards the first opening 112 is located in front of the plate surface away from the first opening 112; that is, along the rotation direction when the first cap body 1 is screwed out relative to the second cap body 2, the end of the spiral section 122 near the first opening 112 is located behind the end of the spiral section 122 away from the first opening 112.

[0055] Firstly, the spiral segment 122 can drive the honey and other ingredients to rotate relative to the stirring element 24, thereby cooperating with the stirring element 24 to achieve a stirring effect. Secondly, when the first cap 1 is unscrewed, the surface in front of the spiral segment 122 is tilted downwards, and the contact surface between the honey pushed by the spiral segment 122 and the spiral segment 122 is located above this part of the honey. Under the action of gravity, this part of the honey can more easily detach from the spiral segment 122, which is conducive to improving the honey discharge efficiency. Thirdly, when the spiral segment 122 rotates relative to the bottom cap 22, it can squeeze the honey and other ingredients located on the bottom cap 22, accelerating the discharge of the honey and other ingredients.

[0056] The bottle cap described in this embodiment, through the cooperation of the push plate 12 and the stirring component 24, can fully stir the honey and other ingredients in the storage chamber 111 during the process of the first bottle cap body 1 being rotated out relative to the second bottle cap body 2 to open the first opening 112; the spiral section 122, in cooperation with the bottom cap 22, can also squeeze the honey to make it discharge from the first opening 112.

[0057] Furthermore, the pusher plate 12 also includes a first flat plate segment 121 and a second flat plate segment 123 disposed at both ends of the spiral segment 122. The first flat plate segment 121 and the second flat plate segment 123 are disposed along a first direction, that is, the first flat plate segment 121 and the second flat plate segment 123 can be vertical plates as described above. On the one hand, the vertical plates can also play a role in pushing the honey and other ingredients to move. On the other hand, compared with the spiral plate, the vertical plates can be more firmly connected to the inner wall of the storage cavity 111, which is conducive to improving the structural strength of the spiral segment 122 and reducing deformation.

[0058] Optionally, at least two push plates 12 are arranged circumferentially around the storage chamber 111. Exemplary, combined with... Figure 7 and Figure 8 The figure shows four push plates 12 arranged circumferentially, and the arc corresponding to the projection of each push plate 12 in the first direction can be 65°-85°.

[0059] Optionally, the pusher plate 12 is spaced apart from the agitator 24 to form a channel between them for the flow of honey, allowing the honey to flow in a first direction toward the first opening 112.

[0060] In some embodiments, combined with Figure 9The bottom cover 22 includes a connected annular edge 221 and a central protrusion 222. The annular edge 221 is connected to the outer cylinder 21, and the central protrusion 222 is a boss protruding from the annular edge 221. The shape and size of the central protrusion 222 can be adapted to the shape and size of the first opening 112, so that the central protrusion 222 can extend into the storage cavity 111 from the first opening 112, and the sidewall of the central protrusion 222 fits against the sidewall of the storage cavity 111 to seal and cover the first opening 112. Of course, in other embodiments, the bottom cover 22 can also seal and cover the first opening 112 by fitting the annular edge 221 against the end face of the first bottle cap body 1.

[0061] In an optional implementation, combined with Figures 9 to 14 The bottom cover 22 is connected to the outer cylinder 21 by a connecting stiffener 25. One end of the connecting stiffener 25 is connected to the annular edge 221, and the other end is connected to the outer cylinder 21. The connecting stiffener 25 can be integrally formed with the outer cylinder 21. The connecting stiffener 25 is a rigid component. The bottom cover 22 and the outer cylinder 21 can be fixedly connected by the connecting stiffener 25, so that the bottom cover 22 can move with the outer cylinder 21.

[0062] Furthermore, in order to allow the honey flowing out of the first opening 112 to continue to be released outward, there is a release channel 26 between the bottom cover 22 and the outer cylinder 21. The release channel 26 can be the gap between adjacent connecting ribs 25. When the first cap body 1 is screwed out relative to the second cap body 2, the first opening 112 is opened, and the honey in the storage cavity 111 can flow out sequentially along the first opening 112 and the release channel 26.

[0063] In an optional embodiment, in order to reduce the amount of honey retained on the bottom cover 22, the inner surface 223 of the central protrusion 222 facing the storage cavity 111 is an outwardly convex curved surface, so that the honey falling onto the inner surface 223 can continue to flow to the surroundings.

[0075] In one embodiment, the second bottle cap 2 is threadedly engaged with the bottle body 4, and the middle part of the second bottle cap 2 has a through channel connecting the receiving cavity 41 and the outside; the first bottle cap 1 is threadedly engaged with the second bottle cap 2, and the first bottle cap 1 passes through the through channel.

[0076] In an optional embodiment, to facilitate user twisting, the outer walls of the first outer shell 13 and the second outer shell 23 are provided with anti-slip textures. The user can open the first bottle cap 1 by applying a reverse torque to the first outer shell 13 and the second outer shell 23, and open the second bottle cap 2 by applying a reverse torque to the second outer shell 23 and the bottle body 4.

[0077] In an optional implementation, combined with Figures 21 to 23 The beverage bottle also includes a cap 5. The cap 5 has an internal snap-fit ​​structure that engages with the bottle cap, allowing it to snap onto the cap. The cap 5 covers the periphery of the bottle body 4 near the third opening 42, serving a dust-proof function. Exemplarily, the cap 5 snaps into the top cap 3 or the first cap body 1. The cap 5 is a flexible shell that can deform when squeezed by the user.

[0078] The optional method of using the beverage bottle described in this embodiment is as follows: the storage chamber 111 stores honey, and the receiving chamber 41 of the bottle body 4 contains water or other liquids. Before the user opens the bottle, the bottom cap 22 is kept in the state of closing the first opening 112. When the user wants to drink honey water, he first twists the first cap 1 so that the first cap 1 is turned out relative to the second cap 2 to a certain position. At this time, the first opening 112 is open, and the honey can flow into the receiving chamber 41 along the first opening 112 and the release channel 26, and mix with the water in the receiving chamber 41 to form honey water. After the honey has been released, the user twists the first cap 1 in the opposite direction so that the first cap 1 closes the second cap 2 again. The user shakes the beverage bottle to fully mix the water and honey in the receiving chamber 41 and to remove the honey adhering to the side wall of the cap. Finally, the user twists the first cap 1 until the first cap 1 is removed, and the middle channel of the second cap 2 is unobstructed. The user drinks the honey water from this channel.

[0079] The beverage bottle described in this embodiment stores honey inside the cap, making it convenient to carry and simplifying the honey water preparation process. By setting a first cap body 1 and a second cap body 2 with threaded engagement, the first opening 112 can be opened to release honey and then resealed. This allows users to shake the beverage bottle to reduce the amount of honey adhering to the cap, thereby reducing the probability of the cap soiling the surrounding environment when it is removed.

[0080] In addition, the bottle cap described in this embodiment can also be sold separately; the second bottle cap body 2 and the third thread structure 232 can be configured to fit the bottle mouth of common bottles on the market, so that users can install the bottle cap on bottles obtained from other channels and then prepare honey water or other beverages according to the above steps.

[0081] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
