[0044] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0045] The sports drink bottle caps in the relevant technology use a simple cap-type structure, and consumers cannot know whether the cap has been opened during transportation or sales. If the cap is opened, the mouthpiece will be at risk of being contaminated, which will pose a safety hazard to consumers.

[0046] In view of this, in one aspect of the present disclosure, a bottle cap is provided that helps to improve safety in use.

[0047] Figure 1 These are perspective views of other embodiments of the bottle cap according to the present disclosure. Figure 2 These are cross-sectional views of some embodiments of the bottle cap according to this disclosure, with reference to... Figures 1-2 The bottle cap includes: a main body 1, a cap body 2, a flow guide nozzle 3, and an identification component 4.

[0048] The main body 1 is used to connect with the bottle mouth of the bottle body. The inside of the main body 1 has threads, which cooperate with the threads on the outer periphery of the bottle mouth to form a threaded connection.

[0049] The cap 2 is connected to the main body 1 and can be flipped relative to the main body 1 to open or close relative to the main body 1. The cap 2 and the main body 1 may each have a notch along their circumference. A rotating part connects to the notches on the cap 2 and the main body 1 respectively. The cap 2 can be flipped around the main body 1 via the rotating part, thereby opening or closing the cap. The rotating part may include, but is not limited to, a hinge.

[0050] The flow guide nozzle 3 is connected to the main body 1. The flow guide nozzle 3 is independently molded and assembled into the main body 1. The flow guide nozzle 3 has an inner plug structure 32 and an outer sealing structure 33. The inner plug structure 32 extends axially and cooperates with the inner wall of the bottle mouth to form a sealing surface. The outer sealing structure 33 extends radially and cooperates with the outer wall of the bottle mouth to form a sealing surface. A silicone inner gasket can be provided inside the flow guide nozzle 3.

[0051] The identification element 4 is radially disposed between the flow nozzle 3 and the cover 2. The identification element 4 includes a first ring 41 and a second ring 42 connected by a connecting part 40. The identification element 4 has an open position and an closed position.

[0052] The identification element 4 is configured to be held in the unopened position by the cover 2 and the nozzle 3 before the cover 2 is first opened relative to the body 1, and the connecting part 40 is configured to break in response to the opening of the cover 2 relative to the body 1, so that the first ring 41 separates from the second ring 42 and the identification element 4 is in the open position. The open position and the unopened position do not coincide.

[0053] In the unopened position, the identification element 4 is held between the nozzle 3 and the cover 2 by means of interference fit or snap-fit, and the identification element 4 does not undergo relative displacement with the nozzle 3 and the cover 2.

[0054] When the cover 2 is opened for the first time, the connecting part 40 breaks as the cover 2 flips upward relative to the main body 1. The first ring 41 and the second ring 42 separate as the connecting part 40 breaks. The first ring 41 and the second ring 42 are relatively displaced from the guide nozzle 3 and the cover 2, so that the identification element 4 is switched to the open position.

[0055] When the identification element 4 is in the open position, the first ring 41 near the cap 2 moves with the cap 2, and the second ring 42 near the nozzle 3 falls down along the outer periphery of the nozzle 3 onto the upper surface of the main body 1, including but not limited to. When the identification element 4 is in the open position, the consumer can shake the bottle, and the identification element 4 will shake with the bottle.

[0056] In this embodiment, an identification element 4 is provided between the nozzle 3 and the cap 2. The identification element 4 is kept in the unopened position before the cap is opened for the first time, and the connection part 40 of the identification element 4 breaks as the cap is opened, thereby switching to an open position different from the unopened position. This allows consumers to identify whether the cap has been opened before drinking by the different position states of the identification element 4. This helps to reduce the risk of consumers ingesting contaminated mouthpieces and affecting their health, improves product reliability, protects consumer safety, and enhances the user experience.

[0057] refer to Figure 2 In some embodiments, the inner side of the cover 2 has a first limiting portion 21 extending radially toward the guide nozzle 3, and the outer side of the guide nozzle 3 has a second limiting portion 31 extending radially toward the cover 2. The identification member 4 is configured to be held in an unopened position by the first limiting portion 21 and the second limiting portion 31 before the first opening.

[0058] The first limiting part 21 and the second limiting part 31 are, but are not limited to, circular shapes. The first limiting part 21 and the second limiting part 31 cooperate with each other to clamp the identification member 4 radially when it is not in the open position.

[0059] The identification element 4 can also be held between the nozzle 3 and the cover 2 in other ways, for example, by connecting the first ring 41 to the cover 2 and the second ring 42 to the nozzle 3. When the cover 2 is opened for the first time, the first ring 41 will move upward with the cover 2 and the second ring 42 will fall to the surface of the body 1 by its own weight.

[0060] In this embodiment, by providing a first limiting part 21 on the inner wall of the cover 2 and a second limiting part 31 on the outer wall of the guide nozzle 3, the identification part 4 can be stably and reliably clamped in the unopened position before the cover 2 is opened for the first time, and the identification part 4 can be easily assembled.

[0061] Figure 3 This is a perspective view of an identification element based on some embodiments of the bottle cap disclosed herein. Figure 4 This is a bottom view of the identification element according to some embodiments of the bottle cap of this disclosure. Figure 5 This is a cross-sectional view of an identification element according to some embodiments of the bottle cap of this disclosure, with reference to... Figures 2-5In some embodiments, in the unopened position of the identification element 4, the first ring 41 is radially close to the cover 2 relative to the second ring 42, and the first ring 41 has a first protrusion 411 extending radially toward the cover 2.

[0062] The first protrusion 411 is attached to the top of the first limiting part 21, and the first limiting part 21 is configured to cause the first protrusion 411 to flip upward in response to the first opening of the cover 2.

[0063] When in the closed position, the first protrusion 411 rests on the first limiting part 21, and the first limiting part 21 can restrict the first protrusion 411 from moving downward, so that the identification member 4 is more reliably and stably kept in the closed position.

[0064] When the cover 2 is opened relative to the main body 1 for the first time, the first limiting part 21 guides the first protrusion 411 to flip upward along with the cover 2, which makes it easier for the first ring 41 to bend relative to the second ring 42, making the connecting part 40 easier to break, thereby enabling the identification part 4 to reliably switch to the open position.

[0065] In this embodiment, by setting the first protrusion 411 and the first limiting part 21 to cooperate, the identification part 4 is fastened and limited in the unopened position of the identification part 4, and the connecting part 40 breaks more quickly when the cover 2 is opened relative to the main body 1 for the first time, so that the identification part 4 can more reliably show consumers whether the cover 2 is open, and protect consumers' safety.

[0066] refer to Figures 2-5 In some embodiments, the second ring 42 has a second protrusion 421 extending radially toward the guide nozzle 3, the second protrusion 421 being bent relative to the annular body of the second ring 42.

[0067] In the closed position of the identification element 4, the second protrusion 421 rests against the lower part of the second limiting part 31, and the second limiting part 31 is configured to restrict the upward movement of the second protrusion 421. The second limiting part 31 is above the second protrusion 421 and cooperates with the first limiting part 21 to apply a reliable axial limit to the identification element 4.

[0068] When the cover 2 is opened for the first time relative to the main body 1, the first limiting part 21 applies an upward flipping torque to the first protrusion 411, while the second limiting part 31 applies a downward torque to the second protrusion 421. The torques applied by the first limiting part 21 and the second limiting part 31 resist each other, making the first ring 41 and the second ring 42 bend more effectively relative to each other, thereby making the connecting part 40 easier to break, and the identification member 4 can be reliably switched to the open position.

[0069] Furthermore, the first protrusion 411 is positioned axially higher than the second protrusion 421 so that when the cover 2 is opened for the first time, it can better apply force to the connecting part 40, causing the connecting part 40 to break.

[0070] In this embodiment, by setting the second protrusion 421 to cooperate with the first protrusion 411, the identification member 4 can be more securely positioned and clamped in the unopened position, and the connecting part 40 is more likely to break when the cover 2 is opened for the first time, so that the identification member 4 can more reliably show the open state of the cover 2 to the consumer and improve the safety of the consumer's use.

[0071] refer to Figure 2 In some embodiments, the second limiting portion 31 is axially higher than the top of the body 1, and the second ring 42 is configured to fall downward by its own weight in response to the breakage of the connecting portion 40. A distance is provided between the second limiting portion 31 and the upper surface of the body 1 to allow the second ring 42 to slide off after the connecting portion 40 breaks.

[0072] In this embodiment, by setting the second limiting part 31 to be higher than the main body 1 along the axial direction, the second ring 42 has a more obvious axial displacement between the unopened position and the open position of the identification member 4, making it easier for consumers to observe the difference in position and improving the user experience.

[0073] refer to Figure 1 , Figure 3 and Figure 4 In some embodiments, the cover 2 is transparent, and the second ring 42 is a different color from the nozzle 3.

[0074] In this embodiment, by setting the cover 2 as a transparent part and setting the second ring 42 and the guide nozzle 3 as different colors, consumers can more easily perceive the position and status of the second ring 42 through the cover 2, thereby making it easier to identify whether it is open or not, which helps to reduce the difficulty of identification for consumers and improve the purchasing experience.

[0075] refer to Figure 1 , Figure 3 and Figure 4 In some embodiments, in the unopened position of the identification element 4, the first ring 41 is radially closer to the cover 2 relative to the second ring 42. The first ring 41 and the guide nozzle 3 are the same color, while the first ring 41 and the second ring 42 are different colors.

[0076] By setting the first ring 41 and the guide nozzle 3 to the same color, when the identification element 4 is in the closed position, the first ring 41 is located radially outward relative to the second ring 42, and the first ring 41 can block the second ring 42. At this time, only the color of the first ring 41 can be seen.

[0077] When the identification element 4 is in the open position, the first ring 41 and the second ring 42 separate, and the color of the second ring 42 is exposed. Since the second ring 42 is different in color from the guide nozzle and the first ring 41, it is easier for consumers to identify color abnormalities more quickly and conveniently.

[0078] In this embodiment, by setting the color of the first ring 41 located on the radially outer side and the guide nozzle 3 to be the same, and making the colors of the first ring 41 and the second ring 42 different, the visual difference between the identification element 4 in the open position and the closed position can be improved, so that consumers can more easily and quickly determine whether the cover 2 has been opened.

[0079] refer to Figure 3 and Figure 4 In some embodiments, the first ring 41 is made of a light-colored material, and the second ring 42 is made of a dark-colored material. In this embodiment, the first ring 41 may be white, and the second ring 42 may be red, to create a greater visual difference between the first ring 41 and the second ring 42, making it easier for consumers to distinguish them. If the cover 2 has been opened, consumers can effectively identify it without close observation in front of the shelf.

[0080] refer to Figures 2-5 In some embodiments, in the unopened position of the identification element 4, the first ring 41 is radially close to the cover 2 relative to the second ring 42, the second ring 42 including an inner ring body 422 and an outer ring body 423 connected to each other, the inner ring body 422 being radially close to the guide nozzle 3 relative to the outer ring body 423.

[0081] The inner ring body 422 has a blocking portion 422a that is higher than the outer ring body 423 along the axial direction. The radial width of the blocking portion 422a is greater than that of the outer ring body 423. The blocking portion 422a is radially connected to the first ring 41 through the connecting portion 40.

[0082] The cover 2 is a transparent part. The first ring 41, the inner ring 422 and the guide nozzle 3 are the same color, while the outer ring 423 is a different color from the inner ring 422.

[0083] The second ring 42 is configured as a double-layer structure. When the identification element 4 is in the closed position, the inner ring 422 and the first ring 41 respectively shield the outer ring 423 in the radial and axial directions, so as to avoid the color of the outer ring 423 being exposed and causing misunderstanding and confusion to consumers.

[0084] When the identification element 4 is in the open position, the first ring 41 and the second ring 42 separate, and the circumferential surface of the outer ring body 423 is no longer blocked by the first ring 41, revealing a color different from that of the guide nozzle 3, thus providing consumers with clear and direct visual information.

[0085] In this embodiment, the second ring 42 includes an inner ring body and an outer ring body 423. When the identification element 4 is in the unopened position, the outer ring body 423 can be more fully covered and hidden, making the first ring 41, the inner ring body 422 and the guide nozzle 3 the same color. The outer ring body 423 and the inner ring body 422 are set to different colors. When the identification element 4 is in the unopened position, the guide nozzle 3 and the first ring 41 are the same color, making the color of the outer ring body 423 exposed after the cover 2 is opened for the first time more prominent. This helps to improve the ease of consumers' judgment of the opening status, and improves the purchase experience and security.

[0086] refer to Figure 3 and Figure 4 In some embodiments, the first ring 41 is made of a light-colored material, and the outer ring body 423 is made of a dark-colored material.

[0087] In this embodiment, the first ring 41 may be white or white, and the outer ring 423 may be red or red, so that there is a greater visual difference between the first ring 41 and the outer ring 423, making it easier for consumers to distinguish them. If the cover 2 has been opened, consumers can effectively identify it without close observation in front of the shelf.

[0088] refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the connecting portion 40 includes a plurality of connecting bridges circumferentially spaced along the first ring 41 and the second ring 42. The connecting bridges cannot be restored after breakage, reducing the risk of the identification element 4 being repeatedly placed in the inactive position.

[0089] In this embodiment, the first ring 41 and the second ring 42 are connected radially by multiple connecting bridges, making it easier to break the cover 2 when it is opened.

[0090] The first ring 41, the second ring 42 and the connecting part 40 are integrally formed, and the outer ring body 423 and the inner ring body 422 of the second ring 42 are integrally formed. Figure 2 The middle connecting part 40, the inner ring body 422 and the first ring 41 are shown in green, and the outer ring body 423 is shown in red.

[0091] During the bottle cap assembly process, the cap body 2 is first in the open state relative to the main body 1. The identification component 4 is inserted into the inside of the cap body 2 through the first limiting part 21. Then, the cap body 2 is flipped over to close with the main body 1. Finally, the guide nozzle 3 is inserted and installed from the bottom of the main body 1 upwards. At this time, the identification component 4 is in the unopened position.

[0092] In another aspect of the present disclosure, a bottle is provided, comprising: a bottle cap and a bottle body as described in any of the above embodiments, wherein the bottle body and the bottle cap are detachably connected.

[0093] In this embodiment, an identification element 4 is provided between the bottle cap's nozzle 3 and the cap body 2. The identification element 4 is kept in the unopened position before the bottle cap is opened for the first time, and the connection part 40 of the identification element 4 breaks as the bottle cap is opened, thereby switching to an open position different from the unopened position. This allows consumers to identify whether the bottle cap has been opened before drinking by the different position states of the identification element 4. This helps reduce the risk of consumers ingesting contaminated mouthpieces and affecting their health, improves product reliability, protects consumer safety, and enhances the user experience.

[0094] In some embodiments, the bottle is used to hold beverages, honey, or condiments, and consumers can open the cap with one hand, reducing the risk of spillage during use.

[0095] In this embodiment, the bottle can be used to hold beverages such as fruit juice, sports drinks, mineral water, and carbonated drinks, as well as condiments such as honey, soy sauce, and vinegar, and medicines, making it easier for consumers to know whether the bottle has been opened and improving safety.

[0096] The embodiments of this disclosure have now been described in detail. To avoid obscuring the concept of this disclosure, some details known in the art have not been described.
