Description

Technical Field

[0001] This invention relates to the field of bottle technology, and in particular to a solid-liquid separation bottle cap and bottle. Background Technology

[0002] A solid-liquid separation bottle cap is a type of cap that seals a bottle and allows for the storage of brewing materials. The applicant filed a Chinese patent application (application number 202010363519.1) on April 30, 2020, disclosing a solid-liquid separation bottle cap and its bottle. The cap includes a cap body, a storage box built into the cap body, and an elastic element connected to the top of the cap body. The elastic element seals the top opening of the cap body. The inner wall of the cap body has internal threads extending along the central axis of the cap body. The storage box has a storage cavity in the middle, and multiple liquid passage holes communicating with the storage cavity are provided at the top and bottom of the storage box. Because the elastic element is connected to the top of the cap body, the inventors found that integrating the elastic element with the cap body in manufacturing is complex, difficult, and results in high production costs. Furthermore, the elastic element and the cap body cannot be disassembled.

[0003] Then, on October 16, 2023, the applicant applied for a solid-liquid separation bottle cap technology with application number 202322777488.6, which includes a storage box, an elastic deformation sleeve and a cap body. The inner wall of the cap body is provided with an upper pressure ring, a lower pressure ring and an internal thread from top to bottom. There is an accommodating gap between the upper pressure ring and the lower pressure ring. The outer wall of the storage box is provided with a limiting ring. The elastic deformation sleeve is tightly fitted on the top of the storage box and covers the top port of the storage box. The bottom port edge of the elastic deformation sleeve is provided with an outward flange. The cap body is tightly fitted on the outer wall of the elastic deformation sleeve. The top surface of the limiting ring is used to abut against the bottom surface of the outward flange. The outward flange can protrude into the accommodating gap. The lower pressure ring is used to press down the limiting ring. The upper pressure ring is used to press down the top surface of the outward flange. The inner wall of the cap body and the outer wall of the storage box form an installation space. The internal thread protrudes into the installation space. Although the patent document achieves modular assembly of the storage box, elastic deformation sleeve and lid, it adds an assembly operation during use, which is inconvenient and prone to leakage or damage due to improper or incorrect assembly.

[0004] Based on the problems encountered above, the inventors conducted in-depth thinking, research, investigation and practical summary on how to integrate the elastic element (elastic deformation sleeve) with the cover. They finally found that although the elastic element and the cover can be integrated by injection molding, which saves assembly steps and reduces production costs, the elastic element is prone to detach from the cover when it bulges frequently due to insufficient firmness of the soft and hard bond between the elastic element and the cover, resulting in a short service life.

[0005] Therefore, the defects are very obvious, and a solution is urgently needed. Summary of the Invention

[0006] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a solid-liquid separation bottle cap and bottle.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A solid-liquid separation bottle cap includes a cap body, a storage box, and an elastically deformable element capable of recoverable elastic deformation. The inner wall of the cap body is sequentially formed from top to bottom with a lever clamping element, a limiting ring, and an internal thread. The lever clamping element includes a fixing ring and a lever pressure ring. The fixing ring protrudes from the inner wall of the cap body, and the middle part of the lever pressure ring connects to the fixing ring. The connection between the lever pressure ring and the fixing ring forms a lever fulcrum. The inner wall of the cap body, the fixing ring, and the upper part of the lever pressure ring form an insert cavity. The bottom edge of the elastically deformable element has a protruding insert portion, which is inserted into the insert cavity. The elastically deformable element seals the top opening of the cap body. The lower part of the inner wall of the cap body, the limiting ring, and the lever pressure ring forms a... The container has a lower opening. A compression ring protrudes from the top periphery of the storage box. The compression ring can swing back and forth relative to the storage box. The compression ring extends into the container through the lower opening. A limiting ring supports the compression ring. The compression ring abuts against the lower part of the lever pressure ring. The limiting ring and the lower part of the lever pressure ring limit the compression ring within the container. The storage box is located inside the lid and is below the lever clamping element. A bottle opening installation space is formed between the outer wall of the storage box and the internal thread. When the compression ring is subjected to an upward compressive force, the compression ring swings upward and acts on the lower part of the lever pressure ring, causing the lever pressure ring to rotate around the lever fulcrum. The upper part of the lever pressure ring presses the insert onto the inner wall of the lid.

[0008] Furthermore, a first abutting inclined surface is provided on the lower part of the lever pressure ring near the squeeze ring, and a second abutting inclined surface is provided on the side of the squeeze ring near the lever pressure ring. The first abutting inclined surface is used to engage with the second abutting inclined surface.

[0009] Furthermore, the second contacting inclined surface is provided with an arcuate convex surface, which contacts the first contacting inclined surface.

[0010] Furthermore, the bottom surface of the extrusion ring is provided with a pressure-receiving protrusion ring, which extends into the bottle mouth installation space.

[0011] Furthermore, a downward-facing V-groove is provided at the connection between the lever pressure ring and the fixed ring, and the sharp corner of the downward-facing V-groove forms the lever fulcrum.

[0012] Furthermore, the insert is injection molded into the insert cavity, the inner wall of the insert cavity is provided with an uneven inner engagement surface, and the outer wall of the insert is provided with an outer engagement surface, the inner engagement surface and the outer engagement surface engage with each other.

[0013] Furthermore, the elastic deformation component is a soft rubber capable of undergoing recoverable elastic deformation.

[0014] Furthermore, the cover is made of hard plastic or metal.

[0015] Furthermore, the top surface of the elastic deformation component is flush with the top surface of the cover.

[0016] Furthermore, the outer wall of the cover is provided with an anti-slip structure.

[0017] The present invention also provides a bottle, including a bottle body and the above-mentioned solid-liquid separation bottle cap, wherein the external thread and internal thread of the bottle mouth of the bottle body are threadedly connected, the bottle mouth of the bottle body is detachably installed in the bottle mouth installation space, the storage box can extend into the bottle mouth of the bottle body, and the end face of the bottle mouth of the bottle body can apply an upward extrusion force to the extrusion ring.

[0018] The beneficial effects of this invention are as follows: In practical applications, the brewing material is pre-stored in the storage box. The elastic deformable part and the insert are integrally constructed. The insert is injection molded in the insert cavity, so that the elastic deformable part is fixedly connected to the cap through the insert. The internal thread of the cap is threadedly connected to the external thread of the bottle mouth, so that the cap is installed on the bottle mouth. As the cap and the bottle mouth are tightened more and more, the end face of the bottle mouth will press the compression ring upward, so that the compression ring is tilted and swings upward relative to the storage box. The tilted and swinging compression ring will press the lever pressure ring upward, so that the lever pressure ring rotates around the lever fulcrum. The upper part of the rotating lever pressure ring will rotate close to the inner wall of the cap, so that the upper part of the lever pressure ring presses the insert onto the inner wall of the cap, thereby increasing the firmness of the insert installed in the insert cavity and making the connection between the elastic deformable part and the cap more secure. When in use, if the bottle contains liquid and the storage box contains brewing materials that can be mixed with the liquid (such as brewing granules), the bottle can be inverted or pressure can be applied to the bottle to allow the liquid in the bottle to enter the storage box, thus allowing the liquid to brew the materials. During the squeezing of the bottle, the liquid can impact the materials in the storage box, which can accelerate the brewing efficiency of the materials and liquid. Under the pressure, the top surface of the elastic deformation component will elastically deform and bulge outward (expand). Repeated squeezing of the bottle will cause the elastic deformation component to bulge outward intermittently, which is fun and has a good decompression effect. Since the lever pressure ring will press the embedded part of the elastic deformation component against the inner wall of the cap after the cap is tightened on the bottle opening, it will greatly increase the connection between the elastic deformation component and the cap. Therefore, even if the elastic deformation component bulges frequently, it will not easily detach from the cap, greatly extending the service life of the invention and solving the problem of weak soft-hard bonding between the elastic deformation component and the cap. In addition, the bottle mouth end face is in close contact with the compression ring, and the compression ring is in close contact with the lever pressure ring to form a double seal, which helps to ensure the airtightness of the brewing material in the sealed storage box.

Detailed Implementation

[0023] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0024] like Figures 1 to 3As shown, the present invention provides a solid-liquid separation bottle cap, which includes a cap body 1, a storage box 2, and an elastic deformation member 3 capable of recoverable elastic deformation. The cap body 1 is cylindrical, and the inner wall of the cap body 1 is sequentially formed from top to bottom with a lever clamping member 4, a limiting ring 5, and an internal thread 6. The lever clamping member 4 includes a fixing ring 7 and a lever pressing ring 8. The fixing ring 7 protrudes from the inner wall of the cap body 1, and the middle part of the lever pressing ring 8 is connected to the fixing ring 7. The connection between the lever pressing ring 8 and the fixing ring 7 forms a lever fulcrum 9. The inner wall of the cap body 1, the upper part of the fixing ring 7 and the lever pressing ring 8 form an annular insert cavity 10. The bottom edge of the elastic deformation member 3 is integrally formed with an annular insert portion 22, which is inserted into the insert cavity 10. The elastic deformation member 3 seals the top opening of the cap body 1. The lower part of the ring 8 is formed into a cavity 11 with a lower opening. The top periphery of the storage box 2 is provided with a compression ring 12. The compression ring 12 can swing back and forth relative to the storage box 2. The compression ring 12 extends into the cavity 11 through the lower opening. The limiting ring 5 is used to support the compression ring 12. The compression ring 12 abuts against the lower part of the lever pressing ring 8. The limiting ring 5 and the lower part of the lever pressing ring 8 limit the compression ring 12 in the cavity 11. The storage box 2 is set in the cover 1. The storage box 2 is located below the lever pressing member 4. The outer wall of the storage box 2 and the internal thread 6 form a bottle mouth installation space 13. When the compression ring 12 is subjected to an upward pressing force, the compression ring 12 swings upward and acts on the lower part of the lever pressing ring 8, so that the lever pressing ring 8 rotates around the lever fulcrum 9. The upper part of the lever pressing ring 8 presses the insert 22 against the inner wall of the cover 1.

[0025] The present invention also provides a bottle, including a bottle body and the above-mentioned solid-liquid separation bottle cap, wherein the external thread of the bottle mouth of the bottle body is threadedly connected to the internal thread 6, the bottle mouth of the bottle body is detachably installed in the bottle mouth installation space 13, the storage box 2 can extend into the bottle mouth of the bottle body, and the end face of the bottle mouth of the bottle body can apply an upward extrusion force to the extrusion ring 12.

[0026] In practical applications, the brewing materials are pre-stored in the storage box 2. The elastic deformable part 3 and the insert part 22 are integrally injection molded. The insert part 22 is injection molded in the insert cavity 10, so that the elastic deformable part 3 is fixedly connected to the cap 1 through the insert part 22. The internal thread 6 of the cap 1 is threadedly connected to the external thread of the bottle mouth, so that the cap 1 is installed on the bottle mouth. As the cap 1 is tightened more and more on the bottle mouth, the end face of the bottle mouth will press upward against the compression ring 1. 2. This causes the compression ring 12 to tilt and swing upward relative to the storage box 2. The upwardly swinging compression ring 12 will press the lever pressure ring 8 upward, causing the lever pressure ring 8 to rotate around the lever fulcrum 9. The upper part of the rotating lever pressure ring 8 will rotate close to the inner wall of the cover 1, thereby pressing the upper part of the lever pressure ring 8 tightly against the inner wall of the cover 1, so as to increase the firmness of the fitting part 22 installed in the fitting cavity 10, and make the connection between the elastic deformation member 3 and the cover 1 more firm. When in use, if the bottle contains liquid and the storage box 2 contains brewing materials that can be brewed with the liquid (such as brewing granules), the bottle can be inverted or pressure can be applied to the bottle to allow the liquid in the bottle to enter the storage box 2, so that the liquid can brew the materials. During the process of squeezing the bottle, the liquid can impact the materials in the storage box 2, which can speed up the brewing efficiency of the materials and liquid. Under the action of pressure, the top surface of the sealing part 3 will undergo elastic deformation and bulge outward (expand). Repeatedly squeezing the bottle will cause the elastic deformation part 3 to bulge outward intermittently, which is fun and has a good decompression effect. After the cap 1 is tightened onto the bottle neck, the lever pressure ring 8 presses the embedded part 22 of the elastic deformable element 3 against the inner wall of the cap 1, greatly increasing the connection between the elastic deformable element 3 and the cap 1. Therefore, even if the elastic deformable element 3 bulges frequently, it is not easy to detach from the cap 1, greatly extending the service life of the invention and solving the problem of weak soft-hard connection between the elastic deformable element 3 and the cap 1. In addition, the bottle neck end face of the bottle body is in close contact with the compression ring 12, and the compression ring 12 is in close contact with the lever pressure ring 8 to form a double seal, which helps to ensure the airtightness of the brewing material in the sealed storage box 2. Specifically, when the cap 1 and the storage box 2 are assembled, the compression ring 12 on the storage box 2 is forcibly inserted into the cavity 11 from the lower opening of the cavity 11, so that the compression ring 12 is always in close contact with the limiting ring 5 and the lever pressure ring 8, achieving an interference clamping effect, which makes the sealing between the compression ring 12 and the cavity 11 good; Figure 2 As shown, under normal conditions, the elastic force of the insert 22 acts on the upper part of the lever pressure ring 8, causing the lever pressure ring 8 to rotate in the opposite direction around the lever fulcrum 9. This ensures that the lever pressure ring 8 always presses against the compression ring 12, thereby pressing the compression ring 12 against the limiting ring 5. The limiting ring 5 and the lever pressure ring 8 clamp the compression ring 12 with an interference fit, thereby achieving a seal between the lever pressure ring 8 and the compression ring 12, as well as a seal between the compression ring 12 and the limiting ring 5, to achieve a double-layer sealing effect.

[0027] In addition, since the compression ring 12 of the storage box 2 is detachably installed in the cavity 11, the storage box 2 and the cover 1 are modularly assembled, which is beneficial for users to replace the storage box 2 and the brewing materials in the storage box 2 according to actual needs.

[0028] Specifically, the bottom of the storage box 2 is provided with a sealing membrane. Due to the sealing between the lever pressure ring 8 and the compression ring 12 and the sealing between the compression ring 12 and the limiting ring 5, a double-layer seal is achieved, which has good airtightness. Therefore, the storage box 2 can store liquid.

[0029] In this embodiment, a first abutting inclined surface 14 is provided on the lower part of the lever pressure ring 8 near the squeeze ring 12, and a second abutting inclined surface 15 is provided on the side of the squeeze ring 12 near the lever pressure ring 8. The first abutting inclined surface 14 is used to abut against the second abutting inclined surface 15. In practical applications, when the squeeze ring 12 is subjected to an upward squeezing force applied by the bottle mouth end face of the bottle body, the squeeze ring 12 will tilt and swing upward, causing the second abutting inclined surface 15 on the squeeze ring 12 to tilt upward and abut against the first abutting inclined surface 14 of the lever pressure ring 8, thereby causing the lever pressure ring 8 to rotate around the lever fulcrum 9, and thus causing the upper part of the lever pressure ring 8 to press against the insert part 22.

[0030] In this embodiment, the second abutting inclined surface 15 has an annular arcuate convex surface 16, which abuts against the first abutting inclined surface 14. By setting the arcuate convex surface 16 to abut against the first abutting inclined surface 14, the compression ring 12 can always be in contact with the lever compression ring 8, resulting in a good sealing effect and facilitating the compression ring 12 to drive the lever compression ring 8 to rotate around the lever fulcrum 9. In addition, under normal conditions, the elastic force of the insert 22 acts on the upper part of the lever compression ring 8, causing the lever compression ring 8 to rotate in the opposite direction around the lever fulcrum 9, thereby ensuring that the lever compression ring 8 always presses against the arcuate convex surface 16, thus pressing the compression ring 12 against the limiting ring 5. The limiting ring 5 and the lever compression ring 8 clamp the compression ring 12 with an interference fit, thereby achieving a seal between the lever compression ring 8 and the compression ring 12, as well as a seal between the compression ring 12 and the limiting ring 5, to achieve a double-layer sealing effect.

[0031] In this embodiment, a pressure-receiving protrusion 17 is provided on the bottom surface of the compression ring 12, and the pressure-receiving protrusion 17 extends into the bottle mouth mounting space 13. The bottle mouth end face of the bottle body presses the pressure-receiving protrusion 17 upward, causing the compression ring 12 to tilt and swing upward. By adding the pressure-receiving protrusion 17, it is not only beneficial for the bottle mouth end face of the bottle body to press the compression ring 12 upward, and for the pressure-receiving protrusion 17 to be in close contact with the bottle mouth of the bottle body, but also improves the sealing effect between the compression ring 12 and the bottle mouth end face of the bottle body.

[0032] In this embodiment, a downward-facing V-groove 18 is provided at the connection between the lever pressure ring 8 and the fixed ring 7, and the sharp corner of the downward-facing V-groove 18 forms the lever fulcrum 9. This structural design ensures the connection between the lever pressure ring 8 and the fixed ring 7 while allowing the lever pressure ring 8 to rotate relative to the fixed ring 7 around the lever fulcrum 9.

[0033] In this embodiment, the insert portion 22 is injection molded into the insert cavity 10. The inner wall of the insert cavity 10 is provided with an uneven inner engagement surface 19, and the outer wall of the insert portion 22 is provided with an outer engagement surface. The inner engagement surface 19 and the outer engagement surface are matched and interlock with each other. This structural design, through the interlocking of the inner engagement surface 19 and the outer engagement surface, allows the insert portion 22 to be firmly installed in the insert cavity 10, thereby making the connection between the elastic deformable element 3 and the cover 1 more secure.

[0034] In this embodiment, the elastic deformation element 3 is a soft rubber that can undergo recoverable elastic deformation and can be repeatedly pressed and used, while the cover 1 is a hard rubber or metal body.

[0035] In this embodiment, the top surface of the elastic deformation element 3 is flush with the top surface of the cap 1. This structural design, under normal conditions, does not affect the shape of the cap and is generally not noticeable.

[0036] In this embodiment, the outer wall of the cover 1 is provided with an anti-slip structure 20; specifically, the anti-slip structure 20 is a friction texture, such as stripes, mesh patterns, etc. The anti-slip structure 20 plays a role in preventing slippage when the cover 1 is screwed on.

[0037] Specifically, the inner wall of the bottom opening of the cap 1 is provided with a flared slope 21, which guides the bottle mouth of the bottle body, making it easier for the bottle mouth of the bottle body to be installed in the bottle mouth installation space 13.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
