[0002] The present invention belongs to the technical field of beverage packaging, and relates to a bottle cap and a filling product, in particular to a bottle cap and a filling product with pre-set solute. Background Art

[0003] One type of current bottle cap can independently store solutes such as liquids or solid powders. The pre-placed liquid or solid powder in the bottle cap is stored separately from the liquid in the bottle, and the two can be mixed when needed. For example, the bottle cap disclosed in patent CN219566100U includes a bottle cap body, an upper cover, a lower barrel, and an inner barrel. When the bottle cap is in a closed state, the cover is located within the lower end of the lower barrel to seal it. When the bottle cap is in an open state, a gap is formed between the cover and the lower end of the lower barrel, through which the solute in the solute cavity can flow into the bottle, achieving mixing of the solute and the liquid in the bottle. However, this type of bottle cap has the following problems: when drinking, the bottle cap body and upper cover need to be separated from the lower barrel and inner barrel, and then the bottle cap body and upper cover need to be separated from the bottle mouth, which is not convenient to operate.

DETAILED DESCRIPTION

[0017] The preferred embodiments of the present disclosure are described in detail below with reference to the accompanying drawings so that the advantages and features of the present disclosure can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is used to help understand the present disclosure, but does not constitute a limitation of the present disclosure.

[0018] The drawings in Figures 1 to 24 are drawn in true proportion. To maintain the simplicity of the description, the proportions of each component are not listed one by one. However, the proportions and positions of each component should be considered as part of the content of this description.

[0019] The following embodiments relate to a bottle cap that can independently store a solute, which can be honey, fruit juice concentrate, or seasoning. When the bottle cap is in a closed state, the solute is stored independently. When the bottle cap is in an open state, the solute can flow out, for example, into a container below. The following embodiments also relate to a bottled product, which includes a container and the above-mentioned bottle cap. The container has a mouth, and the bottle cap is disposed on the mouth. The bottle cap can independently store a solute, which can be honey, fruit juice concentrate, or seasoning. When the bottle cap is in a closed state, the solute is isolated from a liquid (e.g., water) in the container. When the bottle cap is in an open state, the solute can mix with the liquid in the container. Furthermore, the container can be a bottle.

[0020] Example 1: Figures 1 to 17 illustrate a bottle cap according to this embodiment. As shown in Figures 1 to 17, the bottle cap primarily comprises a fixed cap 1, an outer tube 2, a sealed cap 3, a flip cap 4, and several sealing components. The fixed cap 1, outer tube 2, sealed cap 3, and flip cap 4 are made of plastic, such as polypropylene or polyethylene.

[0021] The fixing cap 1 is used to connect to the mouth of the container. Specifically, the fixing cap 1 is placed over the mouth of the container and secured by threads. Once the fixing cap 1 is attached to the mouth of the bottle, it is essentially not removed from the mouth of the bottle until the liquid in the container has been consumed. As shown in Figure 2, a third anti-theft ring 7 is connected to the bottom of the fixing cap 1. The third anti-theft ring 7 is clamped around the outer surface of the bottle mouth and serves to indicate whether the fixing cap 1 has been opened. Once the fixing cap 1 is twisted, the third anti-theft ring 7 breaks away from the fixing cap 1.

[0022] The outer tube 2 is connected to or integrally formed with the fixed cover 1. In this embodiment, the outer tube 2 and the fixed cover 1 are separate components. In other embodiments, the outer tube 2 and the fixed cover 1 may be integrally formed. As shown in FIG11 , the outer tube 2 is hollow and cylindrical, having an open first upper end 21 and a first lower end 22. The first upper end 21 is inserted into the fixed cover 1 and is fixedly engaged with it.

[0023] The cap 3 is inserted into the outer tube 2 and can rotate and move up and down relative to the outer tube 2. As shown in FIG12 , the cap 3 is a hollow cylindrical body with a storage chamber 30 therein. The cap 3 has an open second upper end 31 and a cap portion 32 that can close the first end.

[0024] As shown in Figures 2, 7, 9, and 10, the flip cover 4 can drive the cover 3 to rotate. The flip cover 4 includes a suction nozzle 41 and a flip cover portion 42 that can be opened or closed relative to the suction nozzle 41. The suction nozzle 41 is connected to the second upper end portion 31 and is in communication with the storage chamber 30. The flip cover portion 42 is hinged to the suction nozzle 41 so that it can be rotated open or closed. In this embodiment, as shown in Figure 10, the suction nozzle 41 and the flip cover 4 are integrally provided and connected by a hinge portion 44, which is a folding line with reduced thickness.

[0025] The bottle cap has three states: a closed state (as shown in Figures 1 and 2), an open state (as shown in Figures 6 and 7), and a drinking state (as shown in Figures 9 and 10). In the closed state, the storage chamber 30 is sealed and disconnected from the outside. Specifically, the cover portion 32 is located within the first lower end portion 22 to seal it, and the flip cover portion 42 closes the mouthpiece 41, sealing the upper end of the storage chamber 30. A fourth sealing ring 39 is provided on the cover portion 32, which seals the cover portion 32 and the lower end portion 22 of the outer tube 2, thereby sealing the lower end of the storage chamber 30. In the open state, the lower end of the storage chamber 30 is open, while the upper end remains sealed. Specifically, the cover portion 32 is separated from (e.g., higher than) the first lower end portion 22, forming a gap 33 between the cover portion 32 and the first lower end portion 22, which connects the storage chamber 30. This gap 33 allows communication with the outside, such as with the space within the container, allowing solutes within the storage chamber 30 to flow out. In the drinking state, the lower end of the storage cavity 30 remains open and the upper end is also open; specifically, the lower end of the storage cavity 30 is still connected to the outside through the gap 33, and the flip cover 42 is open relative to the suction nozzle 41, so that consumers can drink the liquid in the container through the suction nozzle 41.

[0026] As shown in Figures 5, 7, 9, and 10, when the bottle cap is closed, the flip cover 4 and the fixed cover 1 are in contact or located at a first height above the fixed cover 1. When the bottle cap is open and in the drinking state, the flip cover 4 is located at a second height above the fixed cover 1; the second height is greater than the first height. In this embodiment, the first height is zero, that is, the flip cover 4 and the fixed cover 1 are in contact, and the second height is 5-10 mm, specifically 8 mm.

[0027] Furthermore, when the bottle cap is in both the closed and open positions, the flip cover 42 closes the suction nozzle 41 to prevent leakage from above. After the flip cover 42 closes the suction nozzle 41, a seal is established between the two. As shown in Figure 3, the flip cover 42 has a sealing skirt 421 extending vertically. When the sealing skirt 421 is inserted into the suction nozzle 41, it slightly deforms inward, creating an interference fit between the two, providing a good sealing effect.

[0028] It should be noted that one of the design requirements of the bottle cap of this embodiment is that it should not be removed from the container during drinking. Therefore, when drinking, the flip cover 42 is opened, and the liquid in the container is consumed through the suction nozzle 41. Furthermore, to facilitate this usage, seals are provided at multiple locations to prevent potential leakage during drinking. A detailed description is provided below.

[0029] As shown in Figure 3, a first sealing ring 33 is provided on the second upper end 31 of the cap 3 and / or the suction nozzle 41. When the bottle cap is in the closed, open, or drinking position, the second upper end 31 is in sealed contact with the suction nozzle 41 via the first sealing ring 33. Specifically, the first sealing ring 33 is fixed to the second upper end 31 of the cap 3 and is compressed between the upper end surface of the suction nozzle 41 and the second upper end 31. This ensures a seal between the cap 3 and the flip cover 4, preventing leakage.

[0030] As shown in Figures 5 and 8 , a sealing assembly 34 is provided on the first upper end portion 21 of the outer tube 2 and / or the cap 3. When the bottle cap is in the closed, open, and drinking positions, the first upper end portion 21 is in sealing contact with the cap 3 via the sealing assembly 34, thereby achieving a seal between the upper end portion of the outer tube 2 and the cap 3, preventing leakage.

[0031] Specifically, the sealing assembly 34 includes a second sealing ring 341 and a third sealing ring 342, each disposed above and below the cap 3. The first upper end portion 21 includes an inwardly protruding sealing flange 23 and a neck portion 24 located below the sealing flange 23. When the bottle cap is closed, the third sealing ring 342 and the neck portion 24 are in sealing contact, while the second sealing ring 341 and the sealing flange 23 are disengaged. When the bottle cap is open or in the drinking state, the second sealing ring 341 and the sealing flange 23 are in sealing contact, while the third sealing ring 342 and the neck portion 24 are disengaged. In other words, when the bottle cap is closed, the third sealing ring 342 provides a seal between the upper end portion of the outer tube 2 and the cap 3; when the bottle cap is open or in the drinking state, the second sealing ring 341 provides a seal between the upper end portion of the outer tube 2 and the cap 3. 7 to 10 , even after the storage chamber 3 is opened, the container and the bottle cap will not leak, wherein: (1) the suction nozzle 41 of the flip cover 4 and the flip cover portion 42 are sealed by the sealing skirt 421; (2) the flip cover 4 and the blind cover 3 are sealed by the first sealing ring 33; (3) the blind cover 3 and the outer tube 2 are sealed by the second sealing ring 341; and (4) the outer tube 2 and the mouth of the container are sealed by the fifth sealing ring 28 provided on the outer surface of the outer tube 2.

[0032] Furthermore, as shown in Figures 5 and 8 , the cap 3 has a tapered section 35 whose outer diameter gradually decreases from top to bottom. A third sealing ring 342 is disposed on the tapered section 35. When the bottle cap is closed, the tapered section 35 is inserted into the neck 24, with the third sealing ring 342 sealing the gap between them. When the bottle cap is open and in the drinking position, the tapered section 35 is higher than the neck 24. The upper end of the tapered section 35 is provided with an outwardly projecting annular ridge 343, and the second sealing ring 341 is disposed on the upper surface of the annular ridge 343. The third sealing ring 342 is attached to the outer side of the tapered section 35.

[0033] The cap 3 is provided with a first airflow hole 36, which is located below the tapered section 35; a plurality of first airflow holes 36 are spaced apart along the circumferential direction. The outer tube 2 is provided with a second airflow hole 26; a plurality of second airflow holes 26 are spaced apart along the circumferential direction. When the bottle cap is in the open state and the drinking state, as shown in FIG8 , at least one first airflow hole 36 and one second airflow hole 26 are aligned and connected to connect the storage chamber 30 with the outside, specifically, to connect the storage chamber 30 with the interior space of the container. When the solute in the storage chamber 30 flows out, air can flow back into the storage chamber 30, thereby avoiding the formation of a vacuum in the storage chamber 30 and facilitating the outflow of the solute.

[0034] As shown in Figure 7 , the nozzle 41 has a dividing ring 43 that separates its interior into a central portion and an outer space. The upper portion of the dividing ring 43 has multiple third airflow holes 431 for air circulation. These third airflow holes 431 are spaced apart along the circumference. When drinking from a bottle, when it is tilted, the upper third airflow holes 431 are not submerged by the liquid, thus facilitating air flow into the container and helping the liquid to flow out smoothly.

[0035] As shown in Figures 7 and 12 , the outer surface of the cap 3 is provided with an external thread 38, and the inner surface of the outer tube 2 is provided with an internal thread 27. The external thread 38 and the internal thread 27 cooperate with each other, and these two threads are configured to allow the cap 3 to move upward as the flip cover 4 rotates. One or more liquid flow holes 37 are defined in the lower sidewall of the cap 3. When the bottle cap is in the open state or the drinking state, the storage chamber 30 communicates with the gap 33 through the liquid flow holes 37. The liquid flow holes 37 are located below the external thread 38, and the first air flow hole 36 is located above the external thread 38. The second air flow hole 26 is located above the internal thread 27.

[0036] The bottle cap is also equipped with multiple anti-theft identification functions, including a first anti-theft ring 5 and a second anti-theft ring 6 in addition to the third anti-theft ring 7 mentioned above, which will be described in detail below.

[0037] As shown in Figures 3 and 4 , the first anti-theft ring 5 is used to indicate whether the storage chamber 30 has been opened; the second anti-theft ring 6 is used to indicate whether the flip cover 42 has been opened. When the bottle cap is in the closed state, the first anti-theft ring 5 is provided on one of the flip cover 4 or the fixed cover 1 and is connected to the other via a first weak portion 51. The second anti-theft ring 6 is provided on one of the suction nozzle 41 and the flip cover 42 and is connected to the other via a second weak portion 61. The first weak portion 51 and the second weak portion 61 can be broken or removed by external force. When the bottle cap is in the open state, the first weak portion 51 breaks or is removed, while the second weak portion 61 remains in its original state. When the bottle cap is in the drinking state, both the first weak portion 51 and the second weak portion 61 break.

[0038] Furthermore, as shown in Figure 4, the first anti-theft ring 5 is connected to the fixed cover 1 through the first weak portion 51. After assembly, the first weak portion 51 is snap-fitted and fixed to the flip cover 4. When the flip cover 4 is screwed, the first weak portion 51 breaks, and the flip cover 4 moves upward relative to the fixed cover 1. As shown in Figure 3, the second anti-theft ring 6 is connected to the flip cover portion 42 through the second weak portion 61. After assembly, the second weak portion 61 is snap-fitted and fixed to the suction nozzle 41. When the flip cover portion 42 is flipped over, the second weak portion 61 breaks, and the flip cover portion 42 rotates open relative to the suction nozzle 41. Specifically, the first weak portion 51 and the second weak portion 61 may have multiple breakages at intervals, and / or be thinned.

[0039] The cap 3 has a sunken section 301 that can be sunken into the container, and an exposed section 302 that extends above the mouth. In this embodiment, the height of the exposed section 302 is no less than that of the sunken section 301. This means that the majority of the bottle cap is exposed above the container, resulting in a larger storage chamber 30 and increased storage capacity. The outer tube 2 and a portion of the cap 3 extend into the container. When the bottle cap is in the drinking position, the fixed cap 1 remains attached to the mouth.

[0040] Figures 1 to 10 show the use process of the filling product and the bottle cap of this embodiment, which are described as follows:

[0041] Initially, the fixed cap 1 is fixed on the mouth of the container, and the bottle cap is in a closed state, as shown in Figures 1 and 2;

[0042] When it is necessary to mix the solute with the liquid in the container, the flip cover 4 is screwed clockwise in Figure 6, and the flip cover 4 drives the blind cover 3 to rotate. At the same time, under the action of the internal thread 27 and the external thread 38, the blind cover 3 moves upward relative to the outer tube 2, and the flip cover 4 and the blind cover 3 can be moved upward by about 8 mm relative to the outer tube 2 and the fixed cover 1 as a whole, as shown by the arrow on the right side of Figure 6; at this time, the blind cover portion 32 at the bottom end of the blind cover 3 is separated from the lower end of the outer tube 2, and a gap 33 is formed between the two. The solute in the storage chamber 30 flows downward into the container through the liquid flow hole 37 and the gap 33 in the direction indicated by the arrow F in Figure 7; in order to add mixing, the entire container can also be shaken. Due to the effect of each sealing ring, no leakage will occur during the shaking process;

[0043] After the solute flows into the container, the flip cover 42 is opened and the mixed liquid in the container can be drunk from the suction nozzle 41, as shown in Figures 9 and 10.

[0044] Figures 13 to 17 illustrate the filling process of the bottle cap, which is described as follows:

[0045] First, press the outer tube 2 into the fixed cover 1, as shown in Figure 13;

[0046] Press the blind cover 3 into the outer tube 2, wherein the upper portion of the blind cover 3 is located inside the fixed cover 1, as shown in Figures 14 and 15;

[0047] A solute, typically a liquid such as honey, is poured into the cover 3 from above, as shown in FIG16 ;

[0048] The flip cover 4 is pressed onto the blind cover 3, and the third anti-theft ring 7 connected to the flip cover 4 is pressed onto the fixed cover 1. The state after filling the solute and opening the storage chamber 30 is shown in FIG17.

[0049] The bottle cap of this embodiment has the following advantages: it is easy to drink, and you can drink by opening the flip cover 42; it has good sealing performance in the closed state, the open state and even during the shaking and mixing process, and will not leak; air reflux paths are designed in multiple places to facilitate the outflow of solutes and mixed liquids; and filling is convenient.

[0050] Example 2: Referring to Figures 18 to 24 , the bottle cap of this embodiment differs from that of Example 1 in that less of the bottle cap protrudes from the container. Specifically, the height of the exposed section 302 is less than half the height of the sunken section 301; correspondingly, the height of the fixed cap 1 is also less than that of Example 1. Unlike Example 1, the bottle cap of this embodiment is mostly sunken into the container, not affecting the overall appearance of the bottle, resulting in a more aesthetically pleasing design.

[0051] Figures 18 to 23 show the use process of the bottle cap, which is described in detail as follows:

[0052] Initially, the fixed cap 1 is fixed on the mouth of the container, and the bottle cap is in a closed state, as shown in Figures 18 and 19;

[0053] When it is necessary to mix the solute with the liquid in the container, the flip cover 4 is screwed clockwise in Figure 20, and the flip cover 4 drives the blind cover 3 to rotate. At the same time, under the action of the internal thread 27 and the external thread 38, the blind cover 3 moves upward relative to the outer tube 2, and the flip cover 4 and the blind cover 3 can be moved upward by about 8 mm relative to the outer tube 2 and the fixed cover 1 as a whole, as shown by the arrow on the right side of Figure 20; at this time, the blind cover portion 32 at the bottom end of the blind cover 3 is separated from the lower end of the outer tube 2, and a gap 33 is formed between the two. The solute in the storage chamber 30 flows downward into the container through the liquid flow hole 37 and the gap 33 in the direction indicated by the arrow F in Figure 21; in order to add mixing, the entire container can also be shaken. Due to the effect of each sealing ring, no leakage will occur during the shaking process;

[0054] After the solute flows into the container, the flip cover 42 is opened and the mixed liquid in the container can be drunk from the suction nozzle 41, as shown in Figures 22 and 23.
