Description

Technical Field

[0001] The invention relates to the technical field of bottle caps, and in particular to a one-piece cap with an anti-falling function. Background Art

[0002] The bottle caps on traditional bottles or bags usually fall off the bottle, or get caught in the hand, or are placed somewhere else when the bottle is opened for drinking, which is very inconvenient. Moreover, with the recycling of bottles, the proportion of lost bottle caps in recycled bottles is relatively high, which leads to a low recycling rate of bottles.

[0003] In the prior art, such as an environmentally friendly one-piece bottle cap with application number 202220114104.5, it is disclosed that the bottle cap body is connected by a connecting part and an anti-theft ring. On the one hand, its connection effect is limited, which may cause the connecting part to break when opening the cap. On the other hand, its connection form and opening form result in the bottle cap being unable to achieve more functions. For example, it is not suitable for ready-to-use bottle caps, and its usage scenarios are limited. Summary of the invention

[0004] The purpose of the present invention is to provide a one-piece cover with an anti-falling function. During the process of the outer cover rotating upward, the thorn ring is driven to rotate downward to pierce the sealing film. After the outer cover moves upward, its limit strip is still blocked below by the limit block on the bottom cover, which can ensure that the outer cover as a whole will not separate from the bottom cover, and the cover body and the anti-theft ring of the outer cover are connected to form a one-piece cover through a connecting part. After the cover body is flipped relative to the anti-theft ring, it is still connected by the connecting part to ensure that the cover body will not fall off.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is: a one-piece cover with an anti-falling function, comprising:

[0006] A bottom cover is arranged on the bottle body or the bag body, and the bottom cover comprises a first ring body, and a first thread and a second thread are arranged on the inner wall and the outer wall of the first ring body respectively, and a limit strip is arranged on the outer wall of the first ring body below the second thread.

[0007] The thorn ring comprises a second ring body, and abutment blocks and a third thread respectively arranged on the inner wall and outer wall of the second ring body, the second ring body is located in the first ring body, and the two are screwed together through the third thread and the first thread, and the lower end of the second ring body is provided with a thorn portion.

[0008] The outer cover includes an anti-theft ring, a cover body and a connecting part, wherein the connecting part at least includes connecting ribs, and the connecting ribs are elastic at least in the vertical direction. A pair of the connecting ribs are symmetrically arranged to connect the anti-theft ring and the cover body. A limit block is provided on the inner wall of the anti-theft ring, and a fourth thread and a push block are provided in the cover body. The anti-theft ring is sleeved on the lower part of the first ring body, and the limit block is located below the limit bar. The cover body is sleeved on the upper part of the first ring body, and the two are screwed together by the fourth thread and the second thread. The cover body is driven to rotate and move upward to abut the push block against the abutment block, so that the thorn ring rotates and moves downward.

[0009] As a further optimization, the connecting rib includes an integrally formed end block and a U-shaped bar, a pair of the end blocks are respectively arranged on the anti-theft ring and the cover body, and the two ends of the U-shaped bar are respectively connected to a pair of the end blocks. The structure of the U-shaped bar can effectively realize expansion and contraction in the vertical direction, and can avoid fatigue accumulation after bending, and can especially effectively reduce the risk of breakage between the connecting rib and the anti-theft ring / cover body, and prevent the cover body from falling off.

[0010] As a further optimization, an arc-shaped clearance opening is provided at the lower end of the cover body, the middle part of the arc-shaped clearance opening is higher than the two sides thereof, and a pair of connecting ribs are located in the middle part of the arc-shaped clearance opening. The existence of the arc-shaped clearance opening is conducive to setting the molding position of the connecting part.

[0011] As a further optimization, the connecting part also includes an auxiliary support block, a pair of which is arranged at the upper end of the anti-theft ring and is respectively located below both sides of the arc-shaped clearance opening; the anti-theft ring and the arc-shaped clearance opening have the same arc surface structure on one side close to each other.

[0012] As a further optimization, the connecting portion further comprises a support plate, which is arranged at the lower end of the cover body and has a gap between the support plate and the anti-theft ring, and the support plate is located between a pair of the connecting ribs.

[0013] As a further optimization, at least one stop bar is provided on the inner wall of the first ring body at the upper end and the lower end of the first thread, respectively, which can cooperate with the third thread to locate the position of the second ring body relative to the first ring body.

[0014] As a further optimization, auxiliary positioning ribs are provided on the outer wall of the second ring body, and the auxiliary positioning ribs are embedded in the gaps between adjacent baffles to ensure that the second ring body is stable in position without external force.

[0015] As a further optimization, an abutment groove is provided at one end of the abutment block, and a guiding arc surface is provided at the other end.

[0016] As a further optimization, the outer cover also includes a bridge for connecting the anti-theft ring and the cover body. A plurality of the bridges are arranged at intervals, which can not only provide a certain degree of connection stability for the anti-theft ring and the cover body during rotation, but also separate the corresponding positions of the anti-theft ring and the cover body by stretching and breaking after applying a certain degree of external force.

[0017] As a further optimization, the outer wall of the cover body is provided with anti-slip grooves to facilitate applying external force to rotate the outer cover.

[0018] As a further optimization, the bottom cover further comprises a connecting plate, which is arranged at the lower end of the outer side wall of the first ring body for connecting with the bottle body or the bag body.

[0019] Compared with the prior art, the present invention has the following beneficial effects: during the process of the outer cover rotating upward, the thorn ring is driven to rotate downward to pierce the sealing film; after the outer cover moves upward, its limit strip is still blocked below by the limit block on the bottom cover, which can ensure that the outer cover as a whole will not separate from the bottom cover; and the cover body and the anti-theft ring of the outer cover are connected to form a one-piece cover through a connecting part; after the cover body is flipped relative to the anti-theft ring, it is still connected by the connecting part, which ensures that the cover body will not fall off.

[0027] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0028] like Figures 1 to 7As shown, a one-piece cover with an anti-falling function comprises a bottom cover 10, a thorn ring 20 and an outer cover 30. The bottom cover 10 is arranged on a bottle body or a bag body. The bottom cover 10 comprises a first ring body 11, and a first thread 101 and a second thread 102 respectively arranged on the inner wall and the outer wall of the first ring body 11. A limit strip 12 in an enclosed structure is arranged on the outer wall of the first ring body 11 below the second thread 102. The thorn ring 20 comprises a second ring body 21, and abutment blocks 24 and a third thread 201 respectively arranged on the inner wall and the outer wall of the second ring body 21. The second ring body 21 is located in the first ring body 11, and the two are screwed together by the third thread 201 and the first thread 101. The lower end of the second ring body 21 is provided with a thorn portion 22. The outer cover 30 comprises an anti-theft ring 31, a cover body 32 and a connecting portion 33. The connecting portion 33 at least includes a connecting rib 331, which is retractable at least in the vertical direction. A pair of connecting ribs 331 are symmetrically arranged to connect the anti-theft ring 31 and the cover body 32. A limit block 35 is provided on the inner wall of the anti-theft ring 31. A fourth thread 301 and a push block 34 are provided in the cover body 32. There is a gap between the push block 34 and the fourth thread 301 to accommodate the first ring body 11 and the second ring body 21. The anti-theft ring 31 is sleeved on the lower part of the first ring body 11, and the limit block 35 is located below the limit strip 12. The vertical projections of the two are at least partially overlapped. The cover body 32 is sleeved on the upper part of the first ring body 11, and the two are screwed together by the fourth thread 301 and the second thread 102. After being driven, the cover body 32 rotates upward to abut the push block 34 against the abutment block 24, driving the thorn ring 20 to rotate downward.

[0029] In the present invention, when it is necessary to open the bottle or bag, the outer cover 30 is rotated, and the anti-theft ring 31 and the cover body 32 are rotated on the bottom cover 10 (i.e., the first ring body 11) respectively. During the rotation process, the fourth thread 302 on the cover body 32 is screwed with the second thread 102 on the first ring body 11, so that the cover body 32 is rotated and moved upward on the outer side of the first ring body 11. At the same time, the anti-theft ring 31 cannot be rotated and moved upward because its limit block 35 is located below the limit bar 12. Therefore, the cover body 32 can be stretched (deformed) relative to the anti-theft ring by stretching (deforming) the connecting portion 33, i.e., the connecting rib 331. 31 moves upward, and the outer cover 30 abuts against the abutment block 24 on the thorn ring 20 through its push block 34 during the rotation process, and the push block 34 pushes the abutment block 24 to move so that the second ring body 21 rotates and moves downward on the inner side of the first ring body 11 through the cooperation of the third thread 301 and the first thread 101, and then the second ring body 21 drives the thorn part 22 to rotate and move downward to pierce the sealing film on the bottle body or bag body, and the fourth thread 302 moves to the upper end of the second thread 102 during the continuous stretching process of the connecting rib 331, so that the cover body 32 can be separated from the first ring body 11 after turning over to open the bottle body or bag body. In the above process, due to the limitation between the limiting strip 12 and the limiting ring 35, the anti-theft ring 31 cannot be separated from the bottom cover 10, and because the cover body 32 and the anti-theft ring 31 are connected by the connecting rib 331, the cover body 32 will not be separated from the anti-theft ring 31. In addition, when it is necessary to re-close the cover body 32 on the bottom cover 10, first snap the cover body 32 onto the bottom cover 10, and then rotate the cover body 32. The cover body 32 drives the anti-theft ring 31 to rotate on the bottom cover 10 through the connecting rib 331. Due to the cooperation between the fourth thread 301 and the second thread 102, the cover body 32 is rotated downward and the deformation of the connecting rib 331 is restored, until the cover body 32 is restored and stably closed on the bottom cover 10.

[0030] In the present invention, during the process of the outer cover 30 rotating upward, the thorn ring 20 is driven to rotate downward and then pierce the sealing film. After the outer cover 30 moves upward by a corresponding distance, its limit strip 12 is still blocked below by the limit block 35 on the bottom cover 10, ensuring that the outer cover as a whole will not separate from the bottom cover, and the cover body 32 and the anti-theft ring 31 of the outer cover 30 are connected by 33 to form a connected cover, and the connecting rib 331 has a deformation characteristic. After the cover body 32 rotates upward and flips relative to the anti-theft ring 31, it is still connected by the connecting rib 331, ensuring that the cover body 32 will not fall off, so that the connection between the outer cover 30 and the outside and the connection inside the outer cover 30 both have an anti-falling function.

[0031] Specifically, the connecting rib 331 includes an integrally formed end block and a U-shaped strip 3312, a pair of end blocks are a lower end block 33111 and an upper end block 33112, the lower end block 33111 and the upper end block 33112 are respectively formed on the anti-theft ring 31 and the cover body 32, and the two ends of the U-shaped strip 3312 are respectively connected to the lower end block 33111 and the upper end block 33112. In the process of opening the cover body 32, it has a rotating action and an upward movement. In the rotating process, the connecting rib 331 drives the anti-theft ring 31 to rotate synchronously on the one hand, and the connecting rib 331 is stretched on the other hand. The connecting rib 331 is set in the form of two end blocks and a U-shaped strip 3312. In the stretching process, the lower end block 33111 and the upper end block 33112 are respectively vertically connected to the anti-theft ring 31 and the cover body 32, and their vertical shapes can be maintained. Therefore, they are mainly stretched in the vertical direction, and there is no oblique shear stretching. Therefore, the strength of the end block itself and the strength of the end block and the anti-theft ring can be guaranteed. The connection strength between the anti-theft ring 31 / cover body 32, and between the end block and the U-shaped bar 3312, the U-shaped bar 3312 has a structure for storing deformation, so the tensile deformation mainly occurs on the U-shaped bar 3312, and its structure enables it to withstand the distance of the cover body 32 moving upward; when the cover body 32 needs to be flipped, the U-shaped bar 3312 itself has a twist at its middle position, and the bending position on the connecting rib 331 is mainly concentrated at the middle position of the U-shaped bar 3312. The structure of the U-shaped bar 3312 can also avoid bending fatigue, and it is not easy to break, which has a better connection effect on the anti-theft ring 31 and the cover body 32. Therefore, the connecting rib 331 can have a good force-bearing mechanism and force-bearing form in the stretching process and the flipping process through the combination of the end block and the U-shaped bar 3312, the end block realizes stable connection and force, and the U-shaped bar can effectively realize expansion and contraction in the vertical direction, and it is not easy to accumulate fatigue, which can reduce the risk of breakage, increase the service life, and ensure the connection effect of the anti-theft ring 31 and the cover body 32.

[0032] An arc-shaped clearance opening 300 is provided at the lower end of the cover body 32, the middle part of the arc-shaped clearance opening 300 is higher than the two sides thereof, and a pair of connecting ribs 331 is located in the middle part of the arc-shaped clearance opening 300. The existence of the arc-shaped clearance opening 300 can form a larger clearance space between the anti-theft ring 31, which is convenient for the cover body 32 to be flipped relative to the anti-theft ring 31, and is also convenient for arranging the various components of the connecting part 30 therein.

[0033] Preferably, the connecting part 30 also includes an auxiliary support block 332, a pair of auxiliary support blocks 332 are arranged at the upper end of the anti-theft ring 31, and are respectively located below the two sides of the arc-shaped clearance opening 300; the anti-theft ring 31 and the arc-shaped clearance opening 300 have the same arc surface structure on one side close to each other. The cam 331 is used to push the cover 32 into the locking cam 332 so that the locking cam 332 can be locked to the locking cam 332.

[0034] In addition, the connecting portion 30 further includes a support plate 333, which is disposed at the lower end of the cover body and has a gap with the anti-theft ring. The support plate 333 is located between a pair of connecting ribs 331. When the cover body 32 is flipped relative to the anti-theft ring 31, the support plate 333 can be abutted against the second thread 102 of the first ring body 11 after being flipped synchronously, thereby preventing the cover body 32 from flipping and resetting by itself, thereby achieving the positioning of the cover body 32. In addition, the vertical projections of the lower end and the upper end of the support plate 333 are at least partially located on the anti-theft ring 31 and the cover body 32, respectively. It can also abut against the anti-theft ring 31 after the cover body 32 is screwed onto the bottom cover 10 to avoid excessive pressure on the connecting rib 331.

[0035] Regarding the connection between the bottom cover 30 and the thorn ring 20, a first stop bar 1031 is provided on the inner wall of the first ring body 11 at the upper end of the first thread 101, and a second stop bar 1032 is provided at the lower end of the first thread 101. Since the thorn ring 20 (second ring body 21) is threadedly engaged with the first thread 101 through its third thread 201, when the third thread 201 rotates to abut against the first stop bar 1031, the upper end position of the thorn ring 20 can be limited, especially when the third thread 201 rotates to abut against the second stop bar 1032, the lower end position of the thorn ring 20 can be limited to prevent the thorn ring 20 from falling into the bottle body or the bag body after detaching from the bottom cover 10.

[0036] In addition, an auxiliary positioning rib 202 is provided on the outer wall of the second ring body 21, which has a certain width and is located in the extension direction of the upper end of the third thread 201. Two first baffles 1031 and second baffles 1032 are provided to cooperate therewith. There are gaps between the pair of first baffles 1031 and between the pair of second baffles 1032. When the auxiliary positioning rib 202 is located in the gap between the pair of first baffles 1031, the thorn ring 20 is positioned in the gap, and cannot rotate and move down to abut or pierce the sealing film on the bottle body or bag body due to external shaking and other factors without external force. When the outer cover 30 is rotated, it drives the thorn ring 20 to rotate over the first baffle 1031 under the action of external force and then rotate and move down. When the auxiliary positioning rib 202 is located in the gap between the pair of second baffles 1032, it is also positioned without external force and will not fall into the bottle body or bag body even if it shakes.

[0037] An abutment groove 240 is provided at one end of the abutment block 24, and a guide arc surface is provided at the other end. When the outer cover 30 rotates in a specific direction, the push block 34 is embedded in the abutment groove 240 to realize the pushing of the abutment block 24 and the rotation of the thorn ring. If the outer cover 30 rotates in the opposite direction, the push block 34 can pass over the abutment block 24 after deformation with the help of its thin plate structure and the guide arc surface, and cannot push the abutment block 24.

[0038] The outer cover 30 also includes a bridge 36 for connecting the anti-theft ring 31 and the cover body 32. A plurality of bridges 36 are arranged at intervals. The bridge 36 is an injection-molded structure integrally with the outer cover 30. The presence of the bridge 36 can assist the connecting portion 33 in more stably connecting the anti-theft ring 31 and the cover body 32, and maintain the synchronization of the anti-theft ring 31 and the cover body 32 when the outer cover 30 is rotated. The bridge 36 is a point-shaped structure and can also be pulled apart by external force to separate the corresponding positions of the cover body 32 and the anti-theft ring 31.

[0039] The outer wall of the cover body 32 is provided with anti-slip grooves 37 to increase friction to facilitate the rotation of the outer cover 30 .

[0040] In addition, the bottom cover 10 further includes a connecting plate 13 , which is disposed at the lower end of the outer side wall of the first ring body 11 for connecting with the bottle body or the bag body.

[0041] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
