Description

Technical Field

[0001] This utility model relates to the field of beverage container technology, specifically to a ready-to-use beverage bottle cap with built-in solute. Background Technology

[0002] The currently popular ready-to-make cold-brew beverages use cold water instead of hot water. Examples include cold-brewed tea and cold-brewed honey, which taste good, are nutritious, and come in a wide variety. Using a bottle cap with a built-in solute in combination with a mineral water bottle allows for easy preparation of ready-to-make cold-brew beverages with a simple action, catering to the fast-paced lifestyle of modern people. They are convenient to buy and carry when traveling, visiting relatives, shopping, or relaxing, greatly expanding the range of beverage choices. However, current ready-to-make beverage bottle caps used with mineral water bottles have shortcomings in terms of speed, convenience, and shelf life, requiring the design of better caps to address these issues. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a ready-to-use beverage bottle cap with built-in solute, which is more convenient to use and provides more reliable solute sealing protection.

[0004] The technical solution of this utility model is: a ready-to-drink beverage bottle cap with built-in solute, wherein the bottle cap is threadedly connected to the mouth of a mineral water bottle, characterized in that: the bottle cap is composed of a cap body 1, a cap body limiting ring 2, an outer cylinder 3, an inner cylinder 4, a sealing membrane 5, and a sealed cavity 6; the outer cylinder 3 is open at the top and sealed at the bottom, and the solute and the inner cylinder 4 are placed inside the outer cylinder 3; the inner cylinder 4 is open at both ends and slidably fitted onto the inner wall of the outer cylinder 3; a sealing membrane 5 is provided at the top of the outer cylinder 3 to form a sealed cavity 6 inside it; the upper part of the outer cylinder 3 is fitted onto the inner wall of the bottle mouth 7, and an annular seal is provided at the fitting point for sealing the bottle mouth 7. The cap 1 has a surface 3a and an annular limiting step 3b for positioning the bottle mouth 7; the cap 1 is threaded to the bottle mouth 7, and the cap 1 has an annular step 1a for pushing the inner cylinder 4; the lower part of the cap 1 is connected to a tear-off cap limiting ring 2; when mixing beverages, tear off the cap limiting ring 2, tighten the cap 1, and when the cap 1 moves down, the annular step 1a presses down on the sealing film 5 and the inner cylinder 4, causing the sealing film 5 to rupture, the bottom of the inner cylinder 4 to press and tear open the bottom of the outer cylinder 3, and the solute in the sealed cavity 6 falls into the bottle body; when the cap needs to be opened, loosen the cap 1 to disengage from the bottle mouth 7.

[0005] Furthermore, preferably, the top of the outer cylinder 3 is provided with a downwardly curved flange 3c, which can be squeezed and deformed. When the cap 1 is tightened, the flange 3c is squeezed upward with the bottle mouth 7 and gets stuck on the thread side of the inner thread 1b of the cap. When the cap 1 is loosened, the outer cylinder 3, the inner cylinder 4, and the sealing film 5 move upward with the cap 1 until they are separated from the bottle mouth 7.

[0006] Furthermore, preferably, the bottom opening of the inner cylinder 4 is a slanted opening 4a, and the bottom edge of the outer cylinder 3 is a thin-walled structure that can be squeezed and torn.

[0007] Furthermore, preferably, the height of the cover limiting ring 2 is equal to the height of the annular step 1a.

[0008] The beneficial effects of this utility model are as follows: First, the bottle cap is threadedly connected to the mouth 7 of the mineral water bottle; the outer cylinder 3 has an open top and a sealed bottom; the solute and inner cylinder 4 are placed inside the outer cylinder 3; the inner cylinder 4 has openings at both ends that can slide onto the inner wall of the outer cylinder 3; and a sealing film 5 is provided at the top of the outer cylinder 3 to form a sealed cavity 6 inside. This technical solution allows the solute to be stored in the sealed cavity 6, resulting in good sealing performance.

[0009] Secondly, the upper part of the outer cylinder 3 is fitted onto the inner wall of the bottle mouth 7, and the fitting is provided with an annular sealing surface 3a for sealing the bottle mouth 7 and an annular limiting step 3b for positioning the bottle mouth 7. This technical solution ensures the sealing of the connection between the bottle body and the bottle cap, and the positional relationship between the outer cylinder 3 and the bottle mouth 7 can be set as needed.

[0010] The outer cylinder 3 has a downward-curved flange 3c at its top. The flange 3c can be deformed by compression. When the cap 1 is tightened, the flange 3c is pressed upward with the bottle mouth 7 and gets stuck on the thread side of the inner thread 1b of the cap. When the cap 1 is loosened, the outer cylinder 3, inner cylinder 4, and sealing film 5 move upward with the cap 1 until they are disengaged from the bottle mouth 7. This technical solution enables the components to move in coordination, which is convenient and quick.

[0011] The inner cylinder 4 has a slanted opening at the bottom 4a, and the bottom edge of the outer cylinder 3 has a thin-walled structure that can be squeezed and torn. This technical solution improves the rationality of component movement while ensuring the solute sealing requirements, making it more labor-saving and convenient.

[0012] The height of the cap limiting ring 2 is equal to the height of the annular step 1a. This technical solution sets the distance of the annular step 1a as the outer cap descends, ensuring that the downward pressing stroke of the bottom of the inner cylinder 4 is reasonable, so as to completely tear open the bottom of the outer cylinder 3 and allow all the solute to fall into the bottle.

[0018] like Figure 1 , Figure 2 As shown, a ready-to-drink beverage bottle cap with built-in solute is threaded to the mouth of a mineral water bottle. The bottle cap consists of a cap body 1, a cap body limiting ring 2, an outer cylinder 3, an inner cylinder 4, a sealing membrane 5, and a sealed cavity 6. The outer cylinder 3 is open at the top and sealed at the bottom. The solute and the inner cylinder 4 are placed inside the outer cylinder 3. The inner cylinder 4 is open at both ends and can be slidably fitted onto the inner wall of the outer cylinder 3. The sealing membrane 5 is provided at the top of the outer cylinder 3 to form a sealed cavity 6 inside it.

[0019] The upper part of the outer cylinder 3 is sleeved on the inner wall of the bottle mouth 7. The sleeved part is provided with an annular sealing surface 3a for sealing the bottle mouth 7 and an annular limiting step 3b for positioning the bottle mouth 7. This technical solution ensures the sealing of the connection between the bottle body and the bottle cap, and the positional relationship between the outer cylinder 3 and the bottle mouth 7 can be set as needed.

[0020] The cap 1 is threaded to the bottle mouth 7, and the cap 1 has an annular step 1a for pushing the inner cylinder 4. The lower part of the cap 1 is connected to a tear-off cap limiting ring 2. When mixing beverages, tear off the cap limiting ring 2, tighten the cap 1, and when the cap 1 moves down, the annular step 1a presses down on the sealing film 5 and the inner cylinder 4, causing the sealing film 5 to break. The bottom of the inner cylinder 4 is pressed and torn open the bottom of the outer cylinder 3, and the solute in the sealed cavity 6 falls into the bottle body. When the bottle cap needs to be opened, loosen the cap 1 to disengage from the bottle mouth 7.

[0021] As a preferred embodiment, the outer cylinder 3 has a downwardly curved flange 3c at its top. The flange 3c can be deformed by compression. When the cap 1 is tightened, the flange 3c is pressed upward along with the bottle mouth 7 and gets stuck on the thread side of the inner thread 1b of the cap. When the cap 1 is loosened, the outer cylinder 3, inner cylinder 4, and sealing film 5 move upward with the cap 1 until they are disengaged from the bottle mouth 7. This technical solution enables the components to move in synergy, facilitating the quick and easy release of the solute and removal of the cap.

[0022] As a preferred embodiment, the bottom opening of the inner cylinder 4 is a beveled opening 4a, and the bottom edge of the outer cylinder 3 is a thin-walled structure that can be squeezed and torn. This technical solution uses the beveled opening 4a at the bottom of the inner cylinder 4 to squeeze the thin-walled structure at the bottom edge of the outer cylinder 3, thereby improving the rationality of component movement while ensuring the solute sealing requirements, and making it more labor-saving and convenient.

[0023] As a preferred embodiment, the height of the cap retaining ring 2 is equal to the height of the annular step 1a. This technical solution sets the distance of the annular step 1a as the outer cap descends, ensuring that the downward pressing stroke of the bottom of the inner cylinder 4 is reasonable, so as to completely tear open the bottom of the outer cylinder 3 and allow all the solute to fall into the bottle.

[0024] The present invention has been described in detail above through preferred embodiments. However, those skilled in the art should understand that the present invention is not limited to the embodiments described above. Any modifications or equivalent substitutions made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
