Description

Technical Field

[0001] This utility model belongs to the field of bottle cap technology, and in particular relates to a reusable bottle cap structure. Background Technology

[0002] Bottle caps are functional accessories used to seal the openings of various bottles. They work with containers through structures such as threads, snaps, and presses. Their main function is to prevent leakage and contamination of the contents, while ensuring storage safety and ease of use. They are mostly made of plastic, metal, or composite materials and are widely used in the packaging of food, beverages, and other products.

[0003] Most existing bottle caps adopt an integral structure, with the inner sealing layer rigidly coupled to the cap body. After long-term use, the threaded engagement surface is prone to wear and deformation or the sealing ring ages, resulting in a decrease in airtightness and requiring the entire bottle cap to be replaced. This does not meet the development needs of resource conservation and environmental protection, and needs to be improved. Therefore, a reusable bottle cap structure is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a reusable bottle cap structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a reusable bottle cap structure, comprising a cap body, an inner liner provided on the inner wall of the cap body, a threaded inner wall of the inner liner, a sealing gasket fixedly installed on the top of the inner liner, a connection port provided on the inner wall of the cap body, a connecting strip fixedly installed on the outer wall of the inner liner, the connecting strip slidably disposed on the connection port, a through opening provided on the side of the cap body, an insertion port provided on the side of the connecting strip, the through opening facing the insertion port, and an insertion strip slidably disposed on both the through opening and the insertion port, a pull tab fixedly installed on the outer end of the insertion strip, an installation port provided on the end of the insertion strip away from the pull tab, a spring provided in the installation port, a fixing block slidably disposed on the installation port, the two ends of the spring being fixedly installed to the insertion strip and the fixing block respectively, and the spring being pressed between the insertion strip and the fixing block, the connecting strip having a fixing port on the side of the insertion port, and the fixing block and the fixing port being disposed on a matching arc surface.

[0006] As a further description of the above solution: The inner wall of the cap is provided with an inner liner, which is used to seal the bottle mouth. When the inner liner is worn or aged, there is no need to replace the entire cap. Only the inner liner needs to be replaced to restore the sealing performance. This ensures airtightness and hygiene safety while reducing plastic waste by more than 70% and making it easy for the cap to be reused.

[0007] Preferably, the connection port, connecting strip, through port, plug, insert, pull tab, mounting port, spring, fixing block, and fixing port are provided in at least two symmetrical sets.

[0008] As a further description of the above solution: it can improve the stability after the lid and inner liner are connected and fixed.

[0009] Preferably, the size of the connecting strip is adapted to the size of the connecting port, and the size of the through port, the insertion port, and the insertion strip are adapted to each other.

[0010] As a further description of the above solution: it can further improve the stability after the lid and inner liner are connected and fixed.

[0011] Preferably, the edge of the insert away from the pull tab is set on an arc edge.

[0012] As a further description of the above solution: the edge of the insert away from the pull tab is set on the arc edge, which makes it easy to insert the insert into the through and the socket.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-8 This utility model provides a technical solution:

[0028] A reusable bottle cap structure includes a cap body 1, an inner liner 2 on the inner wall of the cap body 1, threads 3 on the inner wall of the inner liner 2, a sealing gasket 4 fixedly installed at the top of the inner liner 2, a connection port 5 on the inner wall of the cap body 1, a connecting strip 6 fixedly installed on the outer wall of the inner liner 2, the connecting strip 6 slidably disposed on the connection port 5, a through-hole 7 on the side of the cap body 1, and an insertion port 8 on the side of the connecting strip 6, the through-hole 7 facing the insertion port 8, and the through-hole 7 and the insertion port 8 slidingly disposed together. There is a plug 9, and a pull tab 10 is fixedly installed on the outer end of the plug 9. An installation port 11 is opened at the end of the plug 9 away from the pull tab 10. A spring 12 is provided in the installation port 11. A fixing block 13 is slidably arranged on the installation port 11. The two ends of the spring 12 are fixedly installed to the plug 9 and the fixing block 13 respectively, and the spring 12 is pressed between the plug 9 and the fixing block 13. A fixing port 14 is opened on the side of the plug 8. The fixing block 13 and the fixing port 14 are arranged on a matching arc surface.

[0029] When the bottle cap is in use, the operator rotates the cap body 1, which drives the inner liner 2 to rotate. The thread 3 on the inner wall of the inner liner 2 engages with the external thread 3 of the bottle mouth. At the same time, the sealing gasket 4 at the top of the inner liner 2 is squeezed and deformed, and fits tightly with the end face of the bottle mouth, forming a double sealing barrier to effectively prevent liquid leakage.

[0030] If the inner wall thread 3 or sealing gasket 4 of the inner liner 2 wears or ages due to long-term use, resulting in a decrease in sealing performance, the operator can pull the insert 9 outward using the pull tab 10. This causes the insert 9 to slide outward between the through port 7 and the insertion port 8. As the insert 9 moves, the fixing block 13 is compressed by the force that pushes the spring 12 back into the mounting port 11, thereby causing the fixing block 13 to disengage from the fixing port 14 on the connecting strip 6. Once the fixing block 13 is completely disengaged from the fixing port 14, the inner liner 2 can be connected via the connecting strip 6. The interface 5 is slid up and removed from the cover 1. Then, the new inner liner 2 is fully slid into the cover 1 through the connecting strip 6 and the connecting port 5. At this time, the through port 7 is directly opposite the insertion port 8. Then, the insert strip 9 is reinserted into the through port 7 and the insertion port 8 through the pull tab 10. During the insertion process, the fixing block 13 is retracted by force. When the end of the insert strip 9 is fully inserted into the insertion port 8, the installation port 11 is directly opposite the fixing port 14. The restoring force of the spring 12 will lock the fixing block 13 into the fixing port 14, thus completing the connection and fixation between the cover 1 and the inner liner 2.

[0031] This bottle cap structure includes an inner liner 2, which is used to seal the bottle opening. When the inner liner 2 becomes worn or aged, there is no need to replace the entire bottle cap; simply replacing the inner liner 2 will restore the sealing performance. This ensures airtightness and hygiene while reducing plastic waste by more than 70% and making the bottle cap easy to reuse.

[0032] The connection port 5, the connecting strip 6, the through port 7, the insertion port 8, the insertion strip 9, the pull tab 10, the mounting port 11, the spring 12, the fixing block 13, and the fixing port 14 are provided with at least two sets of symmetrical components;

[0033] The connection port 5, the connecting strip 6, the through port 7, the insertion port 8, the insertion strip 9, the pull tab 10, the mounting port 11, the spring 12, the fixing block 13, and the fixing port 14 are provided in at least two symmetrical sets, which can improve the stability of the cover 1 and the inner liner 2 after they are connected and fixed.

[0034] The dimensions of the connecting strip 6 are adapted to the dimensions of the connecting port 5, and the dimensions of the through port 7, the insertion port 8, and the insertion strip 9 are adapted to each other;

[0035] The size of the connecting strip 6 is adapted to the size of the connecting port 5, and the sizes of the through port 7, the insertion port 8, and the insertion strip 9 are adapted to each other, which further enhances the stability of the connection between the cover 1 and the inner liner 2, prevents the inner liner 2 from loosening due to vibration or external force during use, and ensures the sealing performance of the inner ring.

[0036] The edge of the insert 9, away from the pull tab 10, is set on a curved edge;

[0037] The edge of the insert 9 away from the pull tab 10 is set on the arc edge, which reduces the obstruction when the insert 9 is inserted into the through port 7 and improves the convenience of replacing the inner liner 2.

[0038] The top edge of the pull tab 10 has an opening 15;

[0039] The top edge of the pull tab 10 has an opening 15, which provides an easy point of force for the operator to apply force, thus making it easier for the operator to pull the pull tab 10.

[0040] Working principle:

[0041] When the bottle cap is in use, the operator rotates the cap body 1, which drives the inner liner 2 to rotate. The thread 3 on the inner wall of the inner liner 2 engages with the external thread 3 of the bottle mouth. At the same time, the sealing gasket 4 at the top of the inner liner 2 is squeezed and deformed, and fits tightly with the end face of the bottle mouth, forming a double sealing barrier to effectively prevent liquid leakage.

[0042] If the inner wall thread 3 or sealing gasket 4 of the inner liner 2 wears or ages due to long-term use, resulting in a decrease in sealing performance, the operator can pull the insert 9 outward using the pull tab 10. This causes the insert 9 to slide outward between the through port 7 and the insertion port 8. As the insert 9 moves, the fixing block 13 is compressed by the force that pushes the spring 12 back into the mounting port 11, thereby causing the fixing block 13 to disengage from the fixing port 14 on the connecting strip 6. Once the fixing block 13 is completely disengaged from the fixing port 14, the inner liner 2 can be connected via the connecting strip 6. The interface 5 is slid up and removed from the cover 1. Then, the new inner liner 2 is fully slid into the cover 1 through the connecting strip 6 and the connecting port 5. At this time, the through port 7 is directly opposite the insertion port 8. Then, the insert strip 9 is reinserted into the through port 7 and the insertion port 8 through the pull tab 10. During the insertion process, the fixing block 13 is retracted by force. When the end of the insert strip 9 is fully inserted into the insertion port 8, the installation port 11 is directly opposite the fixing port 14. The restoring force of the spring 12 will lock the fixing block 13 into the fixing port 14, thus completing the connection and fixation between the cover 1 and the inner liner 2.

[0043] The bottle cap structure is equipped with an inner liner 2, which is used to seal the bottle opening. When the inner liner 2 is worn or aged, there is no need to replace the entire bottle cap. Only the inner liner 2 needs to be replaced to restore the sealing performance. This ensures airtightness and hygiene safety while reducing plastic waste by more than 70% and making the bottle cap easy to reuse.

[0044] in,

[0045] The connection port 5, the connecting strip 6, the through port 7, the insertion port 8, the insertion strip 9, the pull tab 10, the mounting port 11, the spring 12, the fixing block 13, and the fixing port 14 are provided with at least two sets of symmetrical components, which can improve the stability of the cover 1 and the inner liner 2 after they are connected and fixed.

[0046] The size of the connecting strip 6 is adapted to the size of the connecting port 5, and the sizes of the through port 7, the insertion port 8, and the insertion strip 9 are adapted to each other, which further enhances the stability of the connection between the cover 1 and the inner liner 2, prevents the inner liner 2 from loosening due to vibration or external force during use, and ensures the sealing performance of the inner ring.

[0047] The edge of the insert 9 away from the pull tab 10 is set on the arc edge, which reduces the obstruction when the insert 9 is inserted into the through port 7 and improves the convenience of replacing the inner liner 2;

[0048] The top edge of the pull tab 10 has an opening 15, which provides an easy point of force for the operator to apply force, thus making it easier for the operator to pull the pull tab 10.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
