Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold brew tea technology, specifically to a beverage bottle for cold brew tea. Background Technology
[0002] Cold brew tea, as a new way of brewing tea, is gradually gaining popularity among the general public because it allows the release of substances such as tea polyphenols and caffeine from tea leaves to be slower, resulting in a milder and sweeter taste.
[0003] However, existing methods of making cold brew tea have significant shortcomings: traditional cold brew tea preparation often involves directly adding tea leaves to water, keeping the tea leaves and water mixed throughout the process. This makes it difficult to easily separate the tea leaves from the water during drinking, affecting the drinking experience. It usually requires the use of filters or other tools to separate the tea leaves, which is cumbersome. In addition, when people are outdoors and want to drink cold brew tea, they usually have to buy pre-packaged cold brew tea drinks or bring their own loose tea leaves, special brewing containers, and bottled water. Carrying so many items is inconvenient, and the problem of needing to use filters to separate the tea leaves from the water still exists. Utility Model Content
[0004] The purpose of this invention is to provide a beverage bottle for cold brewing tea to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A beverage bottle for cold brewing tea includes a bottle body and a cap threadedly connected to the bottle mouth of the bottle body. The cap includes an outer shell threadedly connected to the bottle body, an inner shell movably disposed inside the outer shell, and a cap connected to the inner shell. The bottom end of the outer shell has an inlet and outlet that communicate with the inner cavity of the outer shell.
[0007] The inner shell has a first working position and a second working position. In the first working position, one end of the inner shell is sealed to the inner bottom wall of the outer shell to completely isolate the inner cavity of the inner shell from the outside of the outer shell. In the second working position, one end of the inner shell is separated from the inner bottom wall of the outer shell, so that the inner cavity of the inner shell is in a conductive state with the outside of the outer shell.
[0008] Preferably, the outer surface of the inner shell is provided with at least one guide groove along the circumferential direction, and a positioning protrusion connected to the inner wall of the outer shell is provided in the guide groove, and the positioning protrusion is arranged along the circumferential direction of the inner wall of the outer shell.
[0009] Preferably, the inner bottom wall of the outer shell is provided with a soft plug, and a sealing groove is provided on the soft plug along the circumferential direction. When the inner shell is in the first working position, one end of the inner shell is located in the sealing groove.
[0010] Preferably, the inner bottom wall of the outer shell is provided with an annular positioning groove, and the sealing groove section of the soft plug is located in the annular positioning groove.
[0011] Preferably, the sealing groove section of the soft plug is interference-fitted into the groove of the annular positioning groove.
[0012] Preferably, the inlet and outlet are distributed along the circumferential direction of the outer casing, and at least one inlet and outlet is provided.
[0013] Preferably, the outer casing is provided with a connecting section, the inner wall of the connecting section is provided with an internal thread, and the outer casing is connected to the external thread of the bottle mouth through the internal thread.
[0014] Preferably, the outer wall of the connecting segment is provided with a first anti-slip texture along the circumferential direction, and the extension direction of the first anti-slip texture is parallel to the vertical axis of the connecting segment.
[0015] Preferably, the outer peripheral surface of the inner shell component near the bottle cap component has vertical textures, and the bottle cap component is tightly connected to the inner shell component at the end with vertical textures by a pressing process.
[0016] Preferably, the outer wall of the bottle cap is provided with a second anti-slip texture along the circumferential direction, and the extension direction of the second anti-slip texture is parallel to the vertical axis of the bottle cap.
[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0018] This invention utilizes an inner shell that abuts against a soft stopper inside an outer shell, allowing tea leaves to be placed inside the inner shell and separated from the water inside the bottle. When the cap is screwed on in the forward direction, water from the bottle enters the inner cavity of the inner shell through the inlet / outlet, mixing the cold water with the tea leaves to complete the cold brewing process. When the cap is screwed on in the reverse direction, the inner shell seals against the soft stopper, conveniently separating the tea leaves from the water, allowing users to drink the tea directly from the bottle and improving the drinking experience. Furthermore, it avoids the need for a filter to filter the tea leaves, and also eliminates the need to carry numerous tea-making utensils when outdoors. It possesses considerable practicality and is worthy of promotion.
[0019] This invention utilizes the structural design of the soft plug to create a double seal when the inner shell and the soft plug come into contact, thus preventing tea leaves from becoming damp and moldy when stored inside the inner shell for extended periods. Attached Figure Description

[0031] The present invention will be further described in detail below with reference to embodiments:
[0032] like Figures 1-10 As shown, this utility model provides a beverage bottle for cold brewing tea, including a bottle body 1 and a cap 2 threadedly connected to the bottle mouth of the bottle body 1. The cap 2 includes an outer shell 21 threadedly connected to the bottle body 1, an inner shell 22 movably disposed inside the outer shell 21, and a bottle cap 23 connected to the inner shell 22. The inner cavity of the inner shell 22 is used to hold tea leaves, and the bottom end of the outer shell 21 is provided with an inlet / outlet 3 communicating with the inner cavity of the outer shell 21.
[0033] The inner shell 22 has a first working position and a second working position. When the inner shell 22 is in the first working position, one end of the inner shell 22 is sealed to the inner bottom wall of the outer shell 21 to completely isolate the inner cavity of the inner shell 22 from the outside of the outer shell 21. When the inner shell 22 is in the second working position, one end of the inner shell 22 is separated from the inner bottom wall of the outer shell 21, so that the inner cavity of the inner shell 22 is kept in a conductive state with the outside of the outer shell 21.
[0034] Combination Figure 3 As shown, further, the outer surface of the inner shell 22 is provided with at least one guide groove 4 along the circumferential direction. A positioning protrusion 5 connected to the inner wall of the outer shell 21 is provided within the guide groove 4, and the positioning protrusion 5 is arranged along the circumferential direction of the inner wall of the outer shell 21. Specifically, this solution uses two guide grooves 4 and two positioning protrusions 5 to ensure that the inner shell 22 can stably rise or fall inside the outer shell 21 when rotating. The guide groove 4 is a spiral guide groove. When the inner shell 22 rotates upwards or downwards, since the positioning protrusion 5 is always within the guide groove 4, after the inner shell 22 has rotated to a certain position, the positioning protrusion 5 can restrict the radial movement of the inner shell 22, preventing detachment.
[0035] It is worth noting that when the inner shell 22 is assembled with the outer shell 21, the inner shell 22 can be pressed into the outer shell 21 with strong force, so that when the outer stepped section of the inner shell 22 contacts the inner stepped section of the outer shell 21, the positioning protrusion 5 can be accurately located in the guide groove 4.
[0036] Combination Figures 4-10 As shown, the inner bottom wall of the outer shell 21 is provided with a soft plug 6, which is preferably made of food-grade silicone. A sealing groove 7 is provided on the soft plug 6 along the circumferential direction. When the inner shell 22 is in the first working position, one end of the inner shell 22 is located in the sealing groove 7. An annular positioning groove 8 is provided on the inner bottom wall of the outer shell 21. The sealing groove 7 section of the soft plug 6 is located in the annular positioning groove 8. The sealing groove 7 section of the soft plug 6 is interference-fitted into the groove of the annular positioning groove 8.
[0037] Combination Figure 6 As shown, specifically, when the inner shell 22 is in the first working position, one end of the inner shell 22 can be placed in the sealing groove 7, and at the same time, the sealing section of the soft plug 6 can be inserted into the inner side of the inner shell 22. Thus, this design can effectively enhance the sealing performance of the inner cavity of the inner shell 22 through sealing at two points, improve the sealing effect, and prevent the tea placed in the inner cavity of the inner shell 22 from easily getting damp and moldy, which has certain practicality.
[0038] Combination Figure 3As shown, the inlet and outlet 3 are further distributed along the circumference of the outer shell 21, and at least one inlet and outlet 3 is provided. Through the design of the inlet and outlet 3, the water resources in the bottle 1 can enter the inner cavity of the inner shell 22 when the inner shell 22 is in the second working position, so as to realize the mixing of cold water and tea leaves, thereby carrying out the cold brewing tea process.
[0039] Combination Figure 2 and Figure 8 As shown, the outer casing 21 is further provided with a connecting section 9, the inner wall of the connecting section 9 is provided with an internal thread, the outer casing 21 is connected to the external thread of the bottle mouth of the bottle body 1 through the internal thread, and the outer wall of the connecting section 9 is provided with a first anti-slip texture along the circumferential direction, the extension direction of the first anti-slip texture is parallel to the vertical axis of the connecting section 9.
[0040] Specifically, the structural design of the first anti-slip texture can increase the friction coefficient of the gripping part, so that when the cap 2 is screwed together or separated from the bottle 1, the hand can be effectively prevented from slipping, significantly improving the convenience and efficiency of operation, while ensuring the stability of force application during the connection or separation process.
[0041] As an example
[0042] Combination Figure 3 As shown, the inner shell 22 has a vertical texture 10 on the outer peripheral surface of one end near the bottle cap 23. The bottle cap 23 is tightly connected to the end of the inner shell 22 with the vertical texture 10 by a pressing process. The outer wall of the bottle cap 23 has a second anti-slip texture along the circumferential direction. The extension direction of the second anti-slip texture is parallel to the vertical axis of the bottle cap 23.
[0043] Specifically, the vertical texture 10 is integrally formed with the inner shell 22, and the bottle cap 23 is tightly connected to the end of the inner shell 22 with the vertical texture 10 through an axial pressing process. This causes the inner wall of the bottle cap 23 to form an interference fit with the corresponding outer peripheral surface of the inner shell 22 after pressing. The vertical texture 10 also provides axial positioning for the two, effectively preventing relative displacement after pressing and ensuring the stability of the connection structure.
[0044] Furthermore, the structural design of the second anti-slip texture can increase the coefficient of friction between the outer wall of the bottle cap 23 and the hand, making it easier for the user to rotate the inner shell 22 by holding the bottle cap 23, avoiding slippage and improving the ease of operation.
[0045] As another embodiment
[0046] The outer circumferential surface of the inner shell 22 near the bottle cap 23 is provided with an external thread texture. The bottle cap 23 is connected to one end of the inner shell 22 by a threaded structure. The outer wall of the bottle cap 23 is provided with a second anti-slip texture along the circumferential direction. The extension direction of the second anti-slip texture is parallel to the vertical axis of the bottle cap 23. The structural design of the second anti-slip texture can increase the friction coefficient between the outer wall of the bottle cap 23 and the hand, making it easier for the user to rotate the inner shell 22 by holding the bottle cap 23, avoiding slippage and improving the ease of operation.
[0047] Specifically, the threaded connection between the bottle cap 23 and the inner shell 22 allows the bottle cap 23 to be opened, making it convenient for the user to replace the tea leaves inside the inner shell 22. When replacing the tea leaves, the user needs to wipe the inner cavity of the inner shell 22 with a clean absorbent cloth or let it air dry naturally to avoid residual moisture causing the newly added tea leaves to become damp, moldy, or have their flavor damaged, thus ensuring the dryness of the tea storage environment and maintaining the original quality of the tea.
[0048] The working principle of this cold brew tea beverage bottle will be explained in detail below.
[0049] like Figures 1-10 As shown, it should be noted that before use, the beverage bottle for cold brewing tea proposed in this utility model contains tea leaves. The tea leaves are put into the inner cavity of the inner shell 22 at the time of leaving the factory, and the bottle cap 23 is tightly connected to the inner shell 22 by an automated device to prevent the tea leaves from leaking out. During the factory process, the inner shell 22 is in the first working position, which effectively separates the tea leaves from the water source. At the same time, the double sealing of the soft stopper 6 can prevent the tea leaves from getting damp and moldy.
[0050] When using the product, the user first inverts the bottle body 1, then screws on the cap 23, causing the cap 23 to rotate the inner shell 22, moving the inner shell 22 from the first working position to the second working position. This ensures that the water in the bottle body 1 can enter the inner cavity of the inner shell 22 through the inlet / outlet 3, thus mixing the cold water with the tea leaves. After inverting the bottle body 1 for a certain period of time, the cold brewing process can be completed.
[0051] When the user needs to drink tea, the cap 23 can be twisted in the opposite direction while the bottle 1 is upside down, causing the inner shell 22 to move from the second working position to the first working position. This allows the inner shell 22 to seal the soft stopper 6, conveniently separating the tea leaves from the tea. Finally, the bottle 1 can be placed upright, and the cap 2 can be opened by twisting the connecting section 9, making it convenient for the user to drink tea without the tea leaves affecting the drinking experience.
[0052] It should be noted that, in the description of this disclosure, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joint" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.
[0053] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
