Description

Technical Field

[0001] This invention relates to the field of bottle cap manufacturing technology, and in particular to a rotatable bottle cap. Background Technology

[0002] Existing champagne packaging uses only traditional corks and metal mesh caps, which are complex to manufacture and seal, resulting in high costs. This new cap is now being used on beer to enhance the appearance and provide a different opening experience. However, removing the outer metal mesh is cumbersome, time-consuming, and inconvenient. During removal, the thumb pressing on the cork must be released, posing a safety hazard, as the uncontrolled internal pressure could force the cork open. This unpredictable burst could cause safety issues; injuries from cork injuries occur worldwide every year. Furthermore, the opening process involves twisting the outer wire mesh seal, removing the mesh, and pushing or rotating the cork to allow internal pressure to force it open, making the process complex. Summary of the Invention

[0003] The purpose of this invention is to provide a rotatable bottle cap to solve the problems existing in the prior art, so that the hand no longer needs to press down the bottle stopper, thus improving the convenience and safety of the opening process.

[0004] To achieve the above objectives, the present invention provides the following solution: The present invention provides a rotatable bottle cap, comprising a sleeve and a stopper;

[0005] The stopper is divided into a sealing part and a pressure-bearing part along its axial direction. The sealing part is slidably inserted into the mouth of the bottle containing the bottle. The pressure-bearing part is located on the side of the bottle mouth away from the bottle body. The pressure-bearing part is connected to a plurality of pressure-bearing protrusions protruding from its outer peripheral wall. Each of the pressure-bearing protrusions is distributed sequentially along the circumference of the pressure-bearing part.

[0006] The sleeve is divided into a rotating part and a pressing part along its axial direction. The rotating part is coaxially rotatably sleeved at the bottle mouth. The pressing part is located on the side of the bottle mouth away from the bottle body and surrounds the outer periphery of the pressure-bearing part. The pressing part is connected with a plurality of pressing protrusions protruding from its inner peripheral wall. When the bottle mouth is sealed, each pressing protrusion abuts against the side of the pressure-bearing protrusion away from the bottle mouth. There is a first gap between two adjacent pressure-bearing protrusions for the pressing protrusion to pass through.

[0007] The crimping part is also connected to a plurality of opening structures protruding from its inner peripheral wall. Each opening structure is correspondingly arranged between two adjacent crimping protrusions and is located on the side of the crimping protrusion near the bottle mouth end face. The opening structure includes a pushing part that pushes the pressure-bearing protrusion circumferentially along the pressure-bearing part and an inserting part that pushes the pressure-bearing protrusion axially along the pressure-bearing part. The pushing part is located behind the pressure-bearing protrusion it pushes in the rotational opening direction. There is a second gap between the pushing part and the crimping protrusion located in front of it in the rotational opening direction, allowing the pressure-bearing protrusion to pass through. The inserting part is connected to the front side of the pushing part in the rotational opening direction and is inserted into the position between the pressure-bearing protrusion and the bottle mouth end face when rotating open.

[0008] Preferably, the plug-in portion extends in the direction of rotational opening and is close to the crimping protrusion located on its front side in the direction of rotational opening.

[0009] Preferably, there is a third gap between the pressure-bearing protrusion and the end face of the bottle opening for the insertion portion to be inserted.

[0010] Preferably, the inner peripheral wall of the rotating part and the outer peripheral wall at the bottle mouth have a threaded structure that allows them to rotate together.

[0011] Preferably, the rotating part is rotatably fitted onto the bottle mouth, and the side of the insertion part near the pressing protrusion has a conical structure, which gradually tilts towards the bottle mouth along the rotation opening direction.

[0012] Preferably, when the edge of the conical structure near the bottle opening is used to seal the bottle opening, it is flush with the side of the pressure-bearing protrusion near the end face of the bottle opening.

[0013] Preferably, the pushing part is connected to the front edge of the crimping protrusion in the direction of rotational opening and extends along the rotation axis of the crimping part.

[0014] Preferably, the crimping protrusions are evenly spaced along the circumference of the crimping portion, and the width of the crimping protrusions along the circumference of the crimping portion matches the width of the second interval.

[0015] Preferably, the pressure-bearing protrusions are evenly distributed along the circumference of the pressure-bearing portion, and the width of the pressure-bearing protrusions along the circumference of the pressure-bearing portion matches the width of the pressing protrusions along the circumference of the pressing portion.

[0016] Preferably, the crimping protrusion is located along the axial direction of the crimping portion at the end of the crimping portion away from the rotating portion, and the pressure-bearing protrusion is located along the axial direction of the pressure-bearing portion at the end of the pressure-bearing portion away from the sealing portion.

[0017] The present invention achieves the following technical effects compared to the prior art:

[0018] Because the rotating part is coaxially rotatably sleeved at the bottle mouth, the pressure-bearing protrusion is pushed along the rotation direction by the pushing part of the opening structure through the overall rotating sleeve, and the insertion part of the opening structure is inserted between the pressure-bearing protrusion and the end face of the bottle mouth, and the pressure-bearing protrusion is lifted from the direction away from the bottle mouth, so that the sealing part is loosened at the bottle mouth, and a gap is created between it and the inner wall of the bottle mouth to allow external air to enter the bottle. When the second gap is aligned with the pressure-bearing protrusion, the pressing protrusion no longer restricts the pressure-bearing protrusion, and the entire bottle stopper is pushed out in the direction away from the bottle mouth by the air pressure inside the bottle. The bottle cap disclosed in this invention can be opened by simply rotating the sleeve, so that the hand no longer needs to press the bottle stopper, which improves the convenience and safety of the opening process.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The purpose of this invention is to provide a rotatable bottle cap to solve the problems existing in the prior art, so that the hand no longer needs to press down the bottle stopper, thus improving the convenience and safety of the opening process.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 7As shown, this embodiment provides a rotatable bottle cap, including a sleeve 1 and a stopper 2. Preferably, the sleeve 1 is made of hard plastic or other hard materials, and the stopper 2 is made of flexible plastic or rubber. The stopper 2 is divided into a sealing part 8 and a pressure-bearing part 9 along its axial direction. The sealing part 8 is slidably inserted into the bottle mouth 3 that holds the bottle, and the pressure-bearing part 9 is located on the side of the bottle mouth 3 away from the bottle body. The pressure-bearing part 9 is connected with a plurality of pressure-bearing protrusions 6 protruding from its outer peripheral wall. The pressure-bearing protrusions 6 are distributed sequentially along the circumference of the pressure-bearing part 9. To facilitate subsequent opening, the stopper 2 can smoothly pass through the sleeve 1 and pop out. Preferably, the main body of the pressure-bearing part 9 and the sealing part 8 are coaxially connected cylindrical structures, and the radial cross-sectional structure of the sealing part 8 matches the cross-sectional structure at the bottle mouth 3 to ensure the tightness between the sealing part 8 and the bottle mouth 3. The sleeve 1 is divided into a rotating part 14 and a pressing part 13 along its axial direction. The rotating part 14 is coaxially rotated and sleeved at the bottle mouth 3. The pressing part 13 is located on the side of the bottle mouth 3 away from the bottle body and surrounds the outer periphery of the pressure-bearing part 9. The pressing part 13 is connected with a plurality of pressing protrusions 4 protruding from its inner peripheral wall. When sealing the bottle mouth 3, each pressing protrusion 4 abuts against the side of each pressure-bearing protrusion 6 away from the bottle mouth 3, so that the pressing protrusion 4 can apply pressure towards the bottle body to the pressure-bearing protrusion 6, and with the friction between the sealing part 8 and the inner wall of the bottle mouth 3, the entire bottle stopper 2 is prevented from popping out. There is a first gap 10 between two adjacent pressure-bearing protrusions 6 for the pressing protrusion 4 to pass through. Preferably, both the pressing protrusion 4 and the pressure-bearing protrusion 6 are fan-shaped structures, and their overall structure gradually decreases from the outer peripheral edge of the bottle mouth 3 to its axial direction.The crimping part 13 is also connected to a plurality of opening structures protruding from its inner peripheral wall. Each opening structure is correspondingly arranged between two adjacent crimping protrusions 4 and is located on the side of the crimping protrusion 4 near the end face of the bottle mouth 3. The opening structure includes a pushing part 12 that pushes the pressure-bearing protrusion 6 circumferentially along the pressure-bearing part 9 and an inserting part 7 that pushes the pressure-bearing protrusion 6 axially along the pressure-bearing part 9. The pushing part 12 is located behind the pressure-bearing protrusion 6 it pushes in the rotational opening direction. There is a second gap 5 between the pushing part 12 and the crimping protrusion 4 located in front of it in the rotational opening direction for the pressure-bearing protrusion 6 to pass through. The inserting part 7 is connected to the front side of the pushing part 12 in the rotational opening direction and is inserted between the pressure-bearing protrusion 6 and the end face of the bottle mouth 3 when rotating open. During the rotational opening process, since the rotating part 14 rotates coaxially... The sleeve is fitted onto the bottle neck 3. By rotating the sleeve 1 as a whole, the pushing part 12 of the opening structure pushes the pressure-bearing protrusion 6 in its rotation direction. The insertion part 7 of the opening structure is inserted between the pressure-bearing protrusion 6 and the end face of the bottle neck 3. The pressure-bearing protrusion 6 is lifted from the direction away from the bottle neck 3, so that the sealing part 8 is loosened at the bottle neck 3 and a gap is created between it and the inner wall of the bottle neck 3 to allow external air to enter the bottle. When the second gap 5 is aligned with the pressure-bearing protrusion 6, the pressing protrusion 4 no longer restricts the pressure-bearing protrusion 6. The entire bottle stopper 2 is pushed out by the air pressure inside the bottle in the direction away from the bottle neck 3. The bottle cap disclosed in this invention can be opened by simply rotating the sleeve 1, so that the hand no longer needs to press the bottle stopper 2, which improves the convenience and safety of the opening process. It should be noted that during the ejection process, the pressure-bearing protrusion 6 passes through the second interval 5, the pressing protrusion 4 passes through the first interval 10, and the main structures of the sealing part 8 and the pressing part 13 pass through the central channel of the rotating part 14 and the pressing part 13 in sequence, completing the overall ejection of the bottle stopper 2.

[0032] In one specific embodiment, the insertion part 7 extends in the direction of rotation and is close to the crimping protrusion 4 located in front of it in the direction of rotation. On the one hand, by extending the insertion part 7 to the crimping protrusion 4 in front of it, the insertion part 7 can fully contact the pressure-bearing protrusion 6, thereby ensuring that the insertion part 7 fully lifts the pressure-bearing protrusion 6. On the other hand, by extending the insertion part 7 to the crimping protrusion 4 in front of it and being close to the crimping protrusion 4, the insertion part 7 no longer occupies the space of the crimping protrusion 4 near the end face of the bottle mouth 3, so as to ensure that the crimping protrusion 4 and the pressure-bearing protrusion 6 are in full contact, and to ensure the effectiveness of the contact between the pressure-bearing protrusion 6 and the entire bottle stopper 2.

[0033] In one specific embodiment, there is a third gap 11 between the pressure-bearing protrusion 6 and the end face of the bottle mouth 3 for the insertion part 7 to be inserted. By setting the third gap 11, the pressure-bearing protrusion 6 and the end face of the bottle mouth 3 are spaced apart, so that the insertion part 7 can be inserted, thereby making it easier for the insertion part 7 to lift the entire bottle stopper 2 and cause it to loosen.

[0034] In one specific embodiment, the inner peripheral wall of the rotating part 14 and the outer peripheral wall of the bottle mouth 3 have a threaded structure for rotational engagement between the two. It should be noted that when the sleeve 1 is sealed to the outer periphery of the bottle stopper 2, the insertion part 7 is located along the axial direction of the bottle mouth 3 on the side of the pressure-bearing protrusion 6 near the end face of the bottle mouth 3. During the rotational opening process, by rotating the sleeve 1, the insertion part 7 extends into the third interval 11, and the pushing part 12 abuts against the side of the pressure-bearing protrusion 6 that is being pushed. Since the rotating part 14 and the bottle... With a threaded fit at the opening 3, the rotating part 14 moves synchronously in the direction away from the bottle body during rotation, causing the insertion part 7 and the pushing part 12 to move synchronously. The insertion part 7 continuously pushes the pressure-bearing protrusion 6 in the direction away from the bottle opening 3, and the pushing part 12 abuts against one side of the pressure-bearing protrusion 6, keeping the pressure-bearing protrusion 6 in the position corresponding to the second interval 5. Once the external air comes into contact with the gas inside the bottle, the entire bottle stopper 2 automatically pops out. Continue rotating the plastic sleeve 1 to remove it from the bottle opening 3, completing the opening. In summary, by setting a threaded structure, the opening of the entire bottle cap is simpler and more convenient, requiring only continuous rotation of the sleeve 1, and effectively improving the opening speed.

[0035] In this embodiment, the installation method includes: rotating the sleeve 1 to install it at the bottle neck 3, but without completing the rotation thread path; passing the bottle stopper 2 through the sleeve 1 and inserting it into the bottle neck 3 until the pressure-bearing protrusion 6 is positioned between the crimping protrusion 4 and the insertion part 7 along the axial direction of the bottle neck 3; continuing to rotate the sleeve 1 so that the pressure-bearing protrusion 6 is engaged between the crimping protrusion 4 and the pushing part 12; and continuing to rotate the sleeve 1 to the final position. Alternatively, the bottle stopper 2 can be first inserted into the bottle neck 3, and the sleeve 1 can be fitted onto the bottle neck 3 and rotated to the final position to complete the seal.

[0036] In another embodiment, the rotating part 14 is fixedly rotatably sleeved at the bottle mouth 3, and the insertion part 7 has a conical structure on the side near the pressing protrusion 4. The conical structure gradually tilts towards the bottle mouth 3 along the rotation opening direction, so that the conical structure is inserted between the pressure-bearing protrusion 6 and the end face of the bottle mouth 3 during the rotation of the insertion part 7. During the rotation, the conical structure gradually lifts the pressure-bearing protrusion 6 and the entire bottle stopper 2 until the pushing part 12 contacts one side of the pressure-bearing protrusion 6, so that the second gap 5 is directly opposite the pressure-bearing protrusion 6, so that the pressure-bearing protrusion 6 is no longer restricted by the pressing protrusion 4, thereby causing the entire bottle stopper 2 to pop out automatically. Preferably, when the edge of the conical structure near the bottle opening 3 is used to seal the bottle opening 3, it is flush with the side of the pressure-bearing protrusion 6 near the end face of the bottle opening 3, so that the insertion part 7 can be inserted into the third gap 11 more smoothly during rotation. More preferably, the surface of the insertion part 7 near the pressing protrusion 4 is divided into a flat section and a conical section. The flat section is parallel to the end face of the bottle opening 3 and is located on the side of the pressure-bearing protrusion 6 near the end face of the bottle opening 3. The conical section is located between the flat section and the pushing part 12, and the conical section gradually tilts towards the bottle opening 3 along the rotation opening direction. During the rotation opening process, the flat section extends into the third gap 11 before the conical section to improve the smoothness of the bottle cap opening.

[0037] In this embodiment, the installation method includes: combining the bottle stopper 2 and the sleeve 1 together, and setting the two together at the bottle mouth 3.

[0038] In one specific embodiment, the pushing part 12 is connected to the front edge of the pressing protrusion 4 along the rotation opening direction and extends along the rotation axis of the pressing part 13, so that the entire opening structure forms a reverse "Z" shape. During the installation of the bottle cap, by rotating the sleeve 1, the pressure-bearing protrusion 6 is fully fitted between the pushing part 12 and the pressing protrusion 4. There is no need to optimize the interval between the pushing part 12 and the pressing protrusion 4 located behind it along the rotation opening direction. That is, there is no need to consider this interval and the structure of the pressure-bearing protrusion 6, which makes the manufacturing process simpler. However, the location of the pushing part 12 is not limited to the above-mentioned location. As another embodiment, there is a fourth gap between the pushing part 12 and the pressing protrusion 4 located behind it in the rotation opening direction. When the structure of the fourth gap is greater than or equal to the pressure bearing protrusion 6, the pressing protrusion 4 needs to be pressed against the pressure bearing protrusion 6 when installing the bottle cap, and the positions of the two remain unchanged. When the structure of the fourth gap is smaller than the pressure bearing protrusion 6, the pressure bearing protrusion 6 can be fully fitted between the pushing part 12 and the pressing protrusion 4 by continuously rotating the sleeve 1 in the rotation installation direction until it is rotated into place.

[0039] In one specific embodiment, the pressing protrusions 4 are evenly distributed around the pressing portion 13, and the width of the pressing protrusions 4 around the pressing portion 13 matches the width of the second interval 5. Preferably, the pressure-bearing protrusions 6 are evenly distributed around the pressure-bearing portion 9, and the width of the pressure-bearing protrusions 6 around the pressure-bearing portion 9 matches the width of the pressing protrusions 4 around the pressing portion 13, so as to simplify the entire bottle cap manufacturing process and facilitate mold making.

[0040] In one specific embodiment, the crimping protrusion 4 is located along the axial direction of the crimping portion 13 at the end position of the crimping portion 13 away from the rotating portion 14, and the pressure-bearing protrusion 6 is located along the axial direction of the pressure-bearing portion 9 at the end position of the pressure-bearing portion 9 away from the sealing portion 8, so as to optimize the entire sleeve 1 and bottle stopper 2 structure, making its structure smaller, thereby saving materials.

[0041] Any adaptive changes made according to actual needs are within the scope of protection of this invention.
