The description of these embodiments is provided to assist understanding of the present utility model, but is not intended to limit the present utility model.

The following examples relate to bottle caps that can independently store solutes, which can be honey, juice concentrate or spices. When the bottle cap is in a closed state, the solute is independently stored. When the closure is in an open state, solute may flow out, for example into an underlying container.

The following embodiments also relate to a filled product comprising a container and a bottle cap as described above. The container has a mouth on which the cap is disposed. The bottle cap can independently store solute, and the solute can be honey, juice concentrate or flavoring. When the bottle cap is in a closed state, the solute is isolated from the liquid (such as water) in the container. When the bottle cap is in an open state, the solute and the liquid in the container can be mixed with each other. Further, the container may be a bottle.

Example 1

Fig. 1 to 17 show a bottle cap of the present embodiment. Referring to fig. 1 to 17, the bottle cap mainly comprises a fixed cap 1, an outer tube 2, a blank cap 3, a flip cap 4 and a plurality of sealing elements. The fixed cap 1, the outer tube 2, the closure cap 3, the flip cap 4 are made of plastic, such as polypropylene, polyethylene, etc.

The fixed cap 1 is used to attach the mouth of a container. Specifically, the fixed cap 1 is fitted over the mouth of the container and is fixed by threads. Once loaded onto the bottle mouth, the fixed cap 1 is not substantially removed from the bottle mouth until the liquid in the container has been drunk. As shown in fig. 2, a third anti-theft ring 7 is connected below the fixed cover 1, and the third anti-theft ring 7 is clamped on the outer side surface of the bottle mouth in a surrounding manner and is used for indicating whether the fixed cover 1 is opened or not. Once the fixed cover 1 is screwed, the third anti-theft ring 7 is broken from the fixed cover 1.

The outer tube 2 is connected with or integrally provided with the fixed cover 1. In this embodiment, both the outer tube 2 and the fixed cover 1 are provided separately. In other embodiments, the outer tube 2 and the stationary cover 1 may be integral. As shown in fig. 11, the outer tube 2 has a hollow cylindrical shape and has an open first upper end 21 and a first lower end 22. The first upper end portion 21 is inserted into the fixed cover 1 and is engaged with each other.

The cover 3 is provided in the outer tube 2 so as to be rotatable and movable up and down with respect to the outer tube 2. As shown in fig. 12, the cap 3 has a hollow cylindrical shape as a whole, the cap 3 has a storage chamber 30 therein, and the cap 3 has an open second upper end 31 and a cap portion 32 capable of closing the first end.

As shown in fig. 2, 7, 9 and 10, the lid 4 can rotate the lid 3. The folder 4 includes a suction nozzle 41 and a folder portion 42 that can be opened or closed with respect to the suction nozzle 41, and the suction nozzle 41 is connected to the second upper end portion 31 and communicates with the storage chamber 30. The flap portion 42 is hinged to the suction nozzle 41 so as to be rotatable to open or close. In this embodiment, as shown in fig. 10, the suction nozzle 41 and the flip cover 4 are integrally provided, and are connected by a hinge portion 44, and the hinge portion 44 is a folding line with a reduced thickness.

The bottle cap has three states, namely a closed state (shown in fig. 1 and 2), an open state (shown in fig. 6 and 7) and a drinking state (shown in fig. 9 and 10). In the closed state, the storage chamber 30 is in a closed state, not communicating with the outside; specifically, the lid portion 32 is located in the first lower end portion 22 to close the first lower end portion 22, and the flip portion 42 closes the mouthpiece 41 to close the upper end of the storage chamber 30. The fourth seal ring 39 is provided on the cap portion 32, and the cap portion 32 and the lower end portion 22 of the outer tube 2 are sealed by the fourth seal ring 39, so that the lower end of the storage chamber 30 is closed. In the open state, the lower end of the storage chamber 30 is open, and the upper end remains closed; specifically, the cap portion 32 is disengaged (e.g., raised) from the first lower end portion 22 to form a gap 33 between the cap portion 32 and the first lower end portion 22, which communicates with each other in the reservoir chamber 30, and communicates with the outside through the gap 33, for example, with the space in the container, so that the solute in the reservoir chamber 30 flows out. In the drinking state, the lower end of the storage chamber 30 remains open, and the upper end is also open; specifically, the lower end of the storage chamber 30 is still in communication with the outside through the gap 33, and the flip part 42 is opened with respect to the mouthpiece 41, so that the consumer can drink the liquid in the container through the mouthpiece 41.

Further, as shown in connection with fig. 5, 7, 9 and 10, the lid 4 and the fixed lid 1 are connected or located at a first height above the fixed lid 1 in the closed state of the bottle cap. When the bottle cap is in an open state and a drinking state, the flip cover 4 is positioned 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 is connected to the fixed cover 1, and the second height is 5-10 mm, specifically 8mm.

Further, the lid cover 42 closes the spout 41 in both the closed and open states to prevent liquid leakage from above. After the flip part 42 closes the suction nozzle 41, the two parts are sealed. As shown in fig. 3, the flip portion 42 has a sealing skirt 421 extending up and down, and after the sealing skirt 421 is inserted into the suction nozzle 41, the sealing skirt 421 is slightly deformed inward, and an interference fit is provided between the sealing skirt 421 and the sealing skirt, so that a good sealing effect is provided.

It should be noted that, one of the design requirements of the bottle cap of this embodiment is: the bottle cap is not removed from the container when drinking. Therefore, in the drinking state, the lid portion 42 is opened to drink the liquid in the container from the mouthpiece 41; meanwhile, in order to match the use mode, sealing elements are arranged at a plurality of positions to avoid the possible liquid leakage in the drinking process. The details are as follows.

As shown in fig. 3, the second upper end 31 of the closure cap 3 and/or the spout 41 is provided with a first sealing ring 33, and the second upper end 31 is in sealing contact with the spout 41 through the first sealing ring 33 when the closure cap is in the closed state, the open state and the drinking state. Specifically, the first seal ring 33 is fixed to the second upper end 31 of the cap 3, and the first seal ring 33 is compressed between the suction nozzle 41 and the upper end surface of the second upper end 31. Thus, sealing between the cover 3 and the lid 4 is achieved, preventing leakage therefrom.

As shown in fig. 5 and 8, the first upper end 21 of the outer tube 2 and/or the closure cap 3 is provided with a sealing assembly 34. The first upper end 21 is in sealing contact with the closure cap 3 through the sealing assembly 34 when the closure cap is in the closed state, the open state and the drinking state, thereby sealing between the upper end of the outer tube 2 and the closure cap 3 and preventing leakage therefrom.

Specifically, the sealing assembly 34 includes a second sealing ring 341 and a third sealing ring 342 that are disposed up and down, and the second sealing ring 341 and the third sealing ring 342 are respectively sleeved on the cover 3. The first upper end 21 has an inwardly projecting sealing flange 23 and a neck 24 below the sealing flange 23. When the bottle cap is in the closed state, the third sealing ring 342 is in sealing contact with the neck 24, and the second sealing ring 341 is separated from the sealing flange 23. The second sealing ring 341 is in sealing contact with the sealing flange 23 and the third sealing ring 342 is separated from the neck 24 when the cap is in an opened state and a drinking state. That is, when the bottle cap is in the closed state, the sealing between the upper end portion of the outer tube 2 and the closure cap 3 is achieved by the third seal ring 342; the second seal 341 seals the upper end of the outer tube 2 from the lid 3 when the lid is in the open or drinking state. Thus, as shown in fig. 7 to 10, after the storage chamber 3 is opened, the container and the bottle cap are not leaked, wherein: (1) The suction nozzle 41 of the flip cover 4 and the flip cover part 42 are sealed by a sealing skirt 421; (2) The flip cover 4 and the blank cap 3 are sealed by a first sealing ring 33; (3) The space between the cover 3 and the outer tube 2 is sealed by a second sealing ring 341; (4) The outer tube 2 and the mouth of the container are sealed by a fifth sealing ring 28 provided on the outer surface of the outer tube 2.

Further, as shown in connection with fig. 5 and 8, the closure cap 3 has a tapered section 35, the outer diameter of the tapered section 35 gradually decreases from top to bottom, and a third seal 342 is provided on the tapered section 35. When the bottle cap is in a closed state, the conical section 35 is inserted into the neck 24, and the conical section and the neck are sealed by the third sealing ring 342; the conical section 35 is higher than the neck 24 in the open and drinking positions of the closure. The upper end of the conical section 35 is provided with an annular convex rib 343 protruding outwards, and the second sealing ring 341 is arranged on the upper surface of the annular convex rib 343; a third seal 342 is attached to the outside of the conical section 35.

The cover 3 is provided with a first air flow hole 36, and the first air flow hole 36 is positioned below the conical section 35; the number of first air flow holes 36 is a plurality of circumferentially spaced apart. The outer tube 2 is provided with a second airflow hole 26; the number of the second air flow holes 26 is a plurality of circumferentially spaced apart. In the opened state and the drinking state of the bottle cap, as shown in fig. 8, at least one first air flow hole 36 and one second air flow hole 26 are aligned and communicated to communicate the storage cavity 30 with the outside, specifically, communicate the storage cavity 30 with the internal space of the container, so that when the solute in the storage cavity 30 flows out, air is supplied to flow back into the storage cavity 30, thereby avoiding the formation of vacuum in the storage cavity 30 and being more beneficial to the outflow of the solute.

As shown in fig. 7, the mouthpiece 41 has a partition ring 43 dividing the space inside into a central portion and an outer ring space, and the partition ring 43 has a plurality of third air flow holes 431 for air flow in an upper portion thereof. The plurality of third air flow holes 431 are spaced apart in the circumferential direction. When the bottle is drunk, the third air flow hole 431 positioned above cannot be used for being overflowed by liquid, so that air can enter the container more conveniently, and the liquid in the bottle can flow out smoothly.

As shown in connection with fig. 7 and 12, the outside surface of the closure 3 is provided with external threads 38, the inside surface of the outer tube 2 is provided with internal threads 27, and the external threads 38 and the internal threads 27 are engaged with each other, and the threads are configured such that the closure 3 moves upward as the flip cap 4 rotates. One or more liquid flow holes 37 are formed in the lower side wall of the cover 3, and the storage chamber 30 is communicated with the gap 33 through the liquid flow holes 37 when the cover is in an opened state and a drinking state. The liquid flow hole 37 is located below the external thread 38, and the first air flow hole 36 is located above the external thread 38. The second airflow aperture 26 is located above the internal threads 27.

The closure is further provided with multiple anti-theft identification features, including a first anti-theft ring 5 and a second anti-theft ring 6 in addition to the third anti-theft ring 7 described above, as will be described in more detail below.

As shown in connection with fig. 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 part 42 has been opened. When the bottle cap is in a closed state, the first anti-theft ring 5 is arranged on one of the flip cover 4 or the fixed cover 1 and is connected to the other through the first weak portion 51, the second anti-theft ring 6 is arranged on one of the suction nozzle 41 and the flip cover 42 and is connected to the other through the second weak portion 61, and the first weak portion 51 and the second weak portion 61 can be broken or removed under external force. When the bottle cap is in an opened state, the first weak portion 51 is broken or removed, and the second weak portion 61 maintains an initial state. In the drinking state of the bottle cap, both the first and second weaknesses 51, 61 are broken.

Further, as shown in fig. 4, the first anti-theft ring 5 is connected to the fixed cover 1 through the first weak portion 51, and after assembly, the first weak portion 51 is fastened 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 fig. 3, the second anti-theft ring 6 is connected to the flip part 42 through the second weak part 61, and after assembly, the second weak part 61 is fastened and fixed to the suction nozzle 41. When the flip part 42 is flipped over, the second weak portion 61 breaks, and the flip part 42 is rotated open with respect to the suction nozzle 41. Specifically, the first and second weak portions 51 and 61 may be spaced apart to begin with a plurality of breaks, and/or reduced in thickness.

The closure 3 has a countersink 301 which can be sunk into the container and an exposed section 302 which emerges from above the mouth. In this embodiment, the height of the exposed section 302 is not less than the height of the sinking section 301. That is, most of the bottle cap is exposed above the container, so that a larger storage chamber 30 can be obtained, and the storage amount of the container can be increased. A portion of the outer tube 2 and the closure 3 extend into the container. When the bottle cap is in a drinking state, the fixed cap 1 is kept in a state of being connected to the mouth.

Fig. 1 to 10 show the use process of the filled product and its cap according to the present embodiment, which is described as follows:

initially, the fixed cap 1 is fixed on the mouth of the container, the cap being in a closed condition, as shown in fig. 1 and 2;

when the solute and the liquid in the container are required to be mixed, the flip cover 4 is screwed clockwise in fig. 6, the flip cover 4 drives the blank cap 3 to rotate, meanwhile, under the action of the internal thread 27 and the external thread 38, the blank cap 3 moves upwards relative to the outer tube 2, and the flip cover 4 and the blank cap 3 can integrally move upwards by about 8mm relative to the outer tube 2 and the fixed cap 1, as shown by arrows on the right side of fig. 6; at this time, the cap portion 32 at the bottom end of the cap 3 is separated from the lower end portion of the outer tube 2, a gap 33 is formed therebetween, and the solute in the reservoir chamber 30 flows down into the container through the liquid flow hole 37 and the gap 33 in the direction indicated by the arrow F in fig. 7; in order to add and mix evenly, the whole container can be shaken, and liquid leakage can not occur in the shaking process due to the action of each sealing ring;

after the solute flows into the container, the flip part 42 is opened, and the mixed liquid in the container can be drunk from the suction nozzle 41, as shown in fig. 9 and 10.

Fig. 13 to 17 show the filling process of the bottle cap, described as follows:

the outer tube 2 is first pressed into the fixed cover 1 as shown in fig. 13;

pressing the cap 3 into the outer tube 2, wherein the upper portion of the cap 3 is located within the fixed cap 1, as shown in fig. 14 and 15;

the top-up closure 3 is filled with a solute, typically a liquid such as honey, as shown in fig. 16;

the flip cover 4 is pressed onto the cover 3 and the third anti-theft ring 7, which connects the flip cover 4, is pressed onto the stationary cover 1. The solute is filled and the state after the reservoir 30 is opened is shown in fig. 17.

The bottle cap of the embodiment has the following advantages: convenient to drink, and can be drunk after the flip cover part 42 is opened; in addition, the sealing performance is better in the closed state, the open state and even in the shaking and mixing process, and no liquid leakage is generated; air reflux passages are designed at a plurality of positions, which is beneficial to outflow of solutes and mixed liquid; and the filling is convenient.

Example 2

Referring to fig. 18 to 24, the bottle cap of the present embodiment is different from embodiment 1 in that: the part of the bottle cap exposed outside the container is less. Specifically, the height of the exposed section 302 is less than half the height of the submerged section 301; accordingly, the height of the fixed cover 1 is also smaller than that of the fixed cover 1 in embodiment 1.

Unlike example 1, most of the bottle caps of this example were immersed in the container, and the overall appearance of the bottle was not affected, resulting in a more beautiful appearance.

Fig. 18 to 23 show the use process of the bottle cap, which is described in detail as follows:

initially, the fixed cap 1 is fixed on the mouth of the container, the cap being in a closed condition, as shown in fig. 18 and 19;
