Description

Technical Field

[0001] This utility model belongs to the technical field of beverage bottle structure, specifically to a tea bag detachable cap. Background Technology

[0002] A tea bag detachable cap is a cap specifically designed for brewing tea, primarily for ease of brewing and drinking. Its structure typically includes the following features: Detachment design: The cap has a dedicated compartment inside for holding the tea bag, separating it from the water and preventing over-steeping that can lead to a bitter taste. Adjustment function: Some designs allow users to adjust the steeping time of the tea bag according to their personal preferences, usually achieved by rotating or moving the compartment. Portability: This type of cap is often used in conjunction with insulated water bottles or teaware, making it convenient to carry and suitable for use in offices, outdoors, and other similar settings. Easy cleaning: The design is usually easy to disassemble for convenient cleaning and maintenance. This innovative design enhances the convenience of brewing tea and the drinking experience, making it ideal for those who enjoy tea anytime.

[0003] For example, Chinese invention patent CN201210299156.5 discloses a tea bag bottle cap, including an outer cap that covers the bottle opening; the outer cap includes a top wall and a ring wall; the ring wall has an internal thread adapted to the external thread on the bottle opening; the outer cap has a tea storage cylinder extending into the bottle opening and a push rod extending downward from the top wall; the tea storage cylinder has a shoulder that connects to the ring wall; a tear groove is provided at the connection between the shoulder and the ring wall; a first gap is provided between the shoulder and the top wall; and a sealing film is provided at the bottom of the tea storage cylinder. Because the shoulder is connected to the outer cap's peripheral wall and has a first gap between it and the top wall, the outer cap cannot move relative to the tea storage cylinder to break the sealing film and fall into the bottle without external torque. However, under external torque, the outer cap separates from the tea storage cylinder, and the outer cap moves downward relative to the tea storage cylinder, causing the tea bag to break the sealing film and fall into the bottle, ensuring the hygiene and safety of the tea in the tea storage cylinder.

[0004] Although this patent allows tea bags to be automatically inserted into the bottle by turning the outer cap, the outer cap needs to be screwed into the bottle opening to insert the tea bags into the bottle. That is, when the outer cap is connected to the bottle opening, it cannot be screwed in too deeply, otherwise the tea bags will fall into the bottle. In actual production, it is not convenient to make the bottle cap and the bottle into a whole product, so it cannot achieve both automatic insertion of tea bags into the bottle and easy connection and installation with the bottle. Utility Model Content

[0005] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a tea bag detachable cap. This application provides the following technical solution:

[0006] The device includes a fixed cylinder, a movable cylinder, and a knob cover. The movable cylinder is slidably fitted inside the fixed cylinder. A partition is provided at the bottom of the fixed cylinder. The bottom of the movable cylinder is close to the partition. The bottom of the knob cover is provided with an outer ring and an inner ring. The outer ring is connected to the top of the fixed cylinder through a first threaded portion, and the inner ring is connected to the top of the movable cylinder through a second threaded portion. The pitch of the second threaded portion is greater than the pitch of the first threaded portion. When the knob cover and the fixed cylinder are rotated along the first threaded portion, the second threaded portion pushes the movable cylinder to slide towards the bottom of the fixed cylinder and pushes open the partition.

[0007] During production, tea bags are placed inside the movable cylinder, which is supported by a partition. Both the movable and fixed cylinders are threadedly connected to the knob cap. When the knob cap is unscrewed from the fixed cylinder, the knob cap and the fixed cylinder move away from each other along the threads, while the movable cylinder slides into the fixed cylinder. As the knob cap rotates, the knob cap and the movable cylinder also move away from each other along the threads. Since the pitch of the second thread is greater than that of the first thread, the relative displacement between the knob cap and the movable cylinder is longer. At this time, the movable cylinder is pushed towards the bottom of the fixed cylinder, pressing against the partition at the bottom of the fixed cylinder, pushing the partition open, and causing the tea bag to fall.

[0008] The second threaded portion includes a helical protrusion disposed on the top of the movable cylinder and a helical groove disposed on the inner ring body.

[0009] In the production of the separate bottle cap, the movable cylinder is connected to the knob cap via the second thread and inverted. The tea bag is then placed inside the movable cylinder. Next, the fixed cylinder is inverted so that it is connected and fixed to the knob cap via the first thread. At this point, the movable cylinder needs to fit inside the fixed cylinder. However, the gap between the movable and fixed cylinders is small, and the movable cylinder is completely enclosed after fitting. During production, only the knob cap can be clamped and positioned. Therefore, the amplitude of the movable cylinder's movement on the knob cap should not be too large, and it is best if it does not move at all. The second thread is designed as a spiral protrusion and a spiral groove, which makes the connection between the movable cylinder and the knob cap more stable and prevents movement, making it suitable for industrial production.

[0010] The fixed cylinder has an annular step on its inner wall and a convex ring on its outer wall. A sealing ring is provided on the annular step. After the movable cylinder slides to the bottom of the fixed cylinder, the bottom of the convex ring abuts against the sealing ring.

[0011] Because there is a gap between the fixed cylinder and the movable cylinder, some water will flow out from the gap when drinking, which is not conducive to drinking. Therefore, by setting a sealing ring between the convex ring and the ring step, the gap is sealed, so that the water only flows out from the center of the movable cylinder, resulting in a better drinking experience.

[0012] The inner wall of the fixed cylinder is provided with several vertical protrusions, and the protruding ring is provided with a one-way locking block. The one-way locking block extends into the protrusions, one side of which is an inclined surface tangent to the outer wall of the protruding ring, and the other side is a vertical surface perpendicular to the outer wall of the protruding ring. When the vertical surface contacts the side wall of the protrusion, it abuts against the protrusion and restricts the rotation of the movable cylinder. When the inclined surface contacts the side wall of the protrusion, it does not restrict the rotation of the movable cylinder. The inclined surface is located in the rotation direction when the knob cover is turned onto the fixed cylinder along the first thread.

[0013] By designing a one-way locking block, during manufacturing, the movable cylinder is connected to the knob cover, and when the fixed cylinder is connected to the knob cover, the knob cover's relative knob direction is the screw-in direction. At this time, the movable cylinder also rotates relative to the fixed cylinder. The surface of the one-way locking block that contacts the convex strip is an inclined surface. Due to the guiding effect of the inclined surface, it can easily slide over the convex strip without abutting against it, allowing the knob cover and the fixed cylinder to be screwed together. When the consumer uses it, the knob cover is screwed out of the fixed cylinder. At this time, the knob cover's relative knob direction is the screw-out direction. The knob cover drives the movable cylinder to rotate, but after the movable cylinder rotates slightly, the vertical surface of the one-way locking block abuts against the convex strip, restricting the rotation of the movable cylinder. When the movable cylinder does not rotate but the knob cover rotates, the second threaded part pushes the movable cylinder to move inside the fixed cylinder.

[0014] A retaining ring is provided on the outer wall of the movable cylinder, and a limiting protrusion is provided on the inner wall of the fixed cylinder. After the movable cylinder slides to the bottom of the fixed cylinder, the retaining ring engages with the limiting protrusion.

[0015] By setting a retaining ring and a limiting protrusion, when the movable cylinder is pushed downward inside the fixed cylinder, the bottom of the protruding ring abuts against the sealing ring, and the retaining ring and the limiting protrusion are locked in place, preventing the movable cylinder from slipping out of the fixed cylinder when drinking.

[0016] A groove is provided at the connection between the edge of the partition and the wall of the fixed cylinder, and the outer edge of the bottom of the movable cylinder has a sharp edge.

[0017] The groove is designed to make the connection between the partition and the fixed cylinder weaker and easier to push open. The edge on the bottom outer edge of the movable cylinder corresponds to the position of the groove. The edge can easily cut open the weak part of the partition, and the user will experience less resistance when turning the knob cover.

[0018] A connecting strip is provided on one side of the partition to connect with the fixed cylinder. The bottom of the movable cylinder is inclined, and the bottom of the movable cylinder above the connecting strip is higher and has a notch.

[0019] A connecting strip is installed so that the partition is connected to the fixed cylinder to prevent the partition from falling off completely. The bottom of the movable cylinder is set at an angle, and the side away from the connecting strip cuts the partition first, with greater pressure. Then it gradually cuts other positions until it reaches the notch. Because of the notch, the connecting strip is not cut. Instead, the bottom of the movable cylinder pushes the partition open, preventing damage to the connecting strip.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] When consumers use it, they only need to unscrew the knob cover, and the movable cylinder will automatically push open the partition to let the tea bag fall down. It is easy to operate. In addition, the knob cover, movable cylinder and fixed cylinder are easy to assemble during manufacturing. Since the knob direction is different during assembly and use, there will be no situation where the movable cylinder is accidentally pushed open and damages the partition. It is suitable for industrial mass production.

[0033] Please refer to Figures 1-5 As shown, this utility model provides a tea bag detachable bottle cap;

[0034] The device includes a fixed cylinder 1, a movable cylinder 2, and a knob cover 3. The movable cylinder 2 is slidably fitted inside the fixed cylinder 1. A partition 11 is provided at the bottom of the fixed cylinder 1. The bottom of the movable cylinder 2 is close to the partition 11. The bottom of the knob cover 3 is provided with an outer ring 31 and an inner ring 32. The outer ring 31 is connected to the top of the fixed cylinder 1 through a first threaded part 4. The inner ring 32 is connected to the top of the movable cylinder 2 through a second threaded part 5. The pitch of the second threaded part 5 is greater than the pitch of the first threaded part 4. When the knob cover 3 and the fixed cylinder 1 are turned along the first threaded part 4, the second threaded part 5 pushes the movable cylinder 2 to slide towards the bottom of the fixed cylinder 1 and pushes open the partition 11.

[0035] The fixing cylinder 1 can be fixed to the bottle body by thread or adhesive bonding.

[0036] The second threaded portion 5 includes a spiral protrusion 51 disposed on the top of the movable cylinder 2 and a spiral groove 52 disposed on the inner ring body 32; the first threaded portion 4 can adopt the commonly used thread structure of bottle caps in the prior art.

[0037] The inner wall of the fixed cylinder 1 is provided with an annular step 12, and the outer wall of the movable cylinder 2 is provided with a convex ring 21. A sealing ring 13 is provided on the annular step 12. After the movable cylinder 2 slides to the bottom of the fixed cylinder 1, the bottom of the convex ring 21 abuts against the sealing ring 13.

[0038] The inner wall of the fixed cylinder 1 is provided with several vertical protrusions 14, and the protruding ring 21 is provided with a one-way locking block 211. The one-way locking block 211 extends into the protrusions 14. One side is an inclined surface tangent to the outer wall of the protruding ring 21, and the other side is a vertical surface perpendicular to the outer wall of the protruding ring 21. When the vertical surface contacts the side wall of the protrusion 14, it abuts against the protrusion 14 and restricts the rotation of the movable cylinder 2. When the inclined surface contacts the side wall of the protrusion 14, it does not restrict the rotation of the movable cylinder 2. The inclined surface is located in the rotation direction when the knob cover 3 is turned onto the fixed cylinder 1 along the first threaded part 4.

[0039] A retaining ring 22 is provided on the outer wall of the movable cylinder 2, and a limiting protrusion 15 is provided on the inner wall of the fixed cylinder 1. After the movable cylinder 2 slides to the bottom of the fixed cylinder 1, the retaining ring 22 engages with the limiting protrusion 15.

[0040] A groove 111 is provided at the connection between the edge of the partition 11 and the wall of the fixed cylinder 1, and a sharp edge 23 is provided on the outer edge of the bottom of the movable cylinder 2.

[0041] A connecting strip 112 is provided on one side of the partition 11 to connect with the fixed cylinder 1. The bottom of the movable cylinder 2 is inclined. The bottom of the movable cylinder 2 above the connecting strip 112 is higher and is provided with a notch 24.

[0042] In practice, during production and assembly, the movable cylinder 2 is connected to the knob cover 3 via the second threaded part 5 and inverted. Then, the tea bag is placed inside the movable cylinder 2. Next, the fixed cylinder 1 is inverted and rotated so that the fixed cylinder 1 and the knob cover 3 are connected and fixed via the first threaded part 4. At this time, the fixed cylinder 1 also rotates relative to the movable cylinder 2. The inclined surface of the limiting protrusion 15 contacts the protrusion 14 inside the fixed cylinder 1 but cannot block it, so it does not affect the rotation of the fixed cylinder 1. The assembly is completed when the fixed cylinder 1 and the knob cover 3 are fully screwed together.

[0043] When the consumer uses the device, unscrew the knob cover 3. The knob cover 3 and the fixed cylinder 1 move away from each other along the first threaded part 4. At this time, the knob cover 3 drives the movable cylinder 2 to rotate. However, after the movable cylinder 2 rotates slightly, the vertical surface of the one-way locking block 211 abuts against the protrusion 14, restricting the rotation of the movable cylinder 2. At this time, the knob cover 3 continues to rotate, and the second threaded part 5 pushes the movable cylinder 2 to move towards the bottom of the fixed cylinder 1 until the knob cover 3 is unscrewed. At this time, the bottom of the protrusion ring 21 abuts against the sealing ring 13 and seals. The retaining ring 22 and the limiting protrusion 15 are also locked. During the movement of the movable cylinder 2, the edge 23 on the lower side of the bottom of the movable cylinder 2 away from the connecting strip 112 first cuts the groove 111 of the partition 11, and then gradually cuts other positions until the two ends of the notch 24. The two ends of the notch 24 push the partition 11 to continue to open, and the tea bag falls into the water bottle connected to the fixed cylinder 1. Start brewing tea, and it can be drunk after a period of time.

[0044] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
