Description

Technical Field

[0001] This invention relates to the field of bottle cap technology, and more particularly to an integrated bottle cap with multi-angle positioning and a bottle using the same. Background Technology

[0002] Bottles are widely used as containers in daily life, such as for beverages or other liquids. Anti-theft rings are usually installed on the bottle openings to prevent the caps from falling off, thus avoiding the situation where the bottle opening cannot be closed due to a lost cap and preventing the waste of the contents of the bottle.

[0003] In the prior art, such as the environmentally friendly one-piece bottle cap with application number 202220114104.5, the bottle cap body is connected by a connecting part and an anti-theft ring. The connecting part is not only prone to breakage, causing the bottle cap body to fall off, but also the bottle cap body is not easy to position after being flipped, and it needs to be pressed by hand to keep it stable during use. Another example is the screw-connecting cap with application number 201420040481.4, which can prevent the bottle cap from falling off and can also hold the bottle structure against the lifting stop to keep the bottle cap at the opening angle without obstructing the bottle mouth. However, its opening angle is limited, and it requires a corresponding matching structure on the bottle and the lifting stop needs to have a specific length to match, thus limiting its application. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated bottle cap with multi-angle positioning and a bottle using it. A limiting plate that cooperates with the positioning plate is set on the anti-theft ring. After the positioning plate is flipped, its end extends into the slot on the limiting plate to fix the positioning plate. The positioning of the angle / position after the flip is flipped does not need to be achieved by the positioning plate and the structure on the bottle body. This reduces the requirements for setting parameters such as the length of the positioning plate or the position of the bottle neck / threads, and has better applicability.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a one-piece bottle cap with a multi-angle positioning flip cap, comprising an anti-theft ring and a flip cap, wherein the lower end of one side of the flip cap is provided with a clearance notch, and further comprising: The connecting structure includes at least one connecting rib disposed within the clearance notch. The connecting rib is elastic, with one end connected to the anti-theft ring and the other end connected to the flip cover. The positioning structure includes a positioning plate and a limiting plate. The positioning plate is disposed at the lower end of the flip cover and located within the clearance notch, forming a gap with the upper end of the anti-theft ring. The limiting plate is disposed on the anti-theft ring, adjacent to the positioning plate and located inside the positioning plate. The projections of the limiting plate and the positioning plate along the radial direction of the anti-theft ring at least partially overlap. At least one slot is provided on the side wall of the limiting plate near the positioning plate. When the flip cover is flipped, the positioning plate is flipped and comes into contact with the limiting plate or the anti-theft ring, or the end portion of the positioning plate extends into the slot.

[0006] As a further optimization, the connecting rib includes a connecting portion and an extension portion. The connecting portion has an L-shaped structure, and the extension portion has a bent structure. A pair of connecting portions are respectively disposed at opposite ends of the extension portion. The other end of one connecting portion is connected to the anti-theft ring, and the other end of the other connecting portion is connected to the flip cover. This can improve the connection stability between the connecting rib and the anti-theft ring and the flip cover.

[0007] As a further optimization, two connecting ribs are provided, which are located on opposite sides of the positioning plate to ensure the stability and balance of the connection between the flip cover and the anti-theft ring.

[0008] As a further optimization, the upper surface of the clearance notch has an arc structure, and the middle position is higher than the two ends. The anti-theft ring is provided with support blocks at both ends of the clearance notch. When the flip cover and the anti-theft ring are rotated at close range, the connecting ribs are prevented from being stressed by the contact between the support blocks and the two sides of the lower surface of the clearance notch.

[0009] As a further optimization, the slot is horizontally inserted through the side wall of the limiting plate on one side; there are two slots.

[0010] As a further optimization, the anti-theft ring includes an outer ring and an inner ring connected to the outer ring and located inside the outer ring after being bent at 180°. The upper end of the inner ring forms a limiting surface, and the limiting plate is formed on the limiting surface.

[0011] As a further optimization, the limiting plate includes a support portion connected to the inner ring and an abutment portion disposed on the support portion away from the inner ring. The slot is formed on the side wall of the abutment portion near the positioning plate. A clearance slope is provided between the support portion and the abutment portion.

[0012] As a further optimization, at least one limiting groove is provided on the side wall of the abutment portion away from the positioning plate, and the limiting groove extends horizontally through the abutment portion on the side wall of the abutment portion.

[0013] As a further optimization, a limiting protrusion is provided on the side wall of the inner ring near the outer ring. The limiting protrusion abuts against the outer ring to ensure that the position of the inner ring allows the limiting surface to abut against the corresponding structure of the bottle.

[0014] The present invention also provides a bottle, including a bottle body and the above-mentioned multi-angle positioning flip cap, wherein a limiting platform is provided at the lower part of the bottle mouth of the bottle body, the flip cap is sleeved on the bottle mouth, and the anti-theft ring abuts against the lower end of the limiting platform, and the limiting plate abuts against the bottle mouth.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. A limiting plate that can cooperate with the positioning plate is set on the anti-theft ring. When the positioning plate is flipped, its end can be inserted into the slot on the limiting plate to fix the positioning plate. The positioning of the positioning plate, that is, the positioning of the angle / position after the flip cap is flipped, does not require the positioning plate to be snapped into the structure on the bottle body (such as the neck or threads). This reduces the requirements for the length of the positioning plate or the position of the neck / thread on the bottle body, and can have better applicability. 2. The limiting plate has a simple molding structure and simple processing technology. Attached Figure Description

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] like Figures 1 to 6As shown, a multi-angle positioning flip cap includes an anti-theft ring 10 and a flip cap 20. A clearance notch 200a is provided at the lower end of one side of the flip cap 20. The flip cap also includes a connecting structure and a positioning structure 40. The connecting structure includes at least one connecting rib 30 disposed within the clearance notch 200a. The connecting rib 30 is telescopic, with one end connected to the anti-theft ring 10 and the other end connected to the flip cap 20. The positioning structure 40 includes a positioning plate 41 and a limiting plate 42. The positioning plate 41 is disposed at the lower end of the flip cap 20 and located at the clearance notch 200a. Within 00a, a gap 200b is formed between the lower end of the positioning plate 41 and the upper end of the anti-theft ring 10. The limiting plate 42 is disposed on the anti-theft ring 10 and is adjacent to the positioning plate 41. The projections of the limiting plate 42 and the positioning plate 41 along the radial direction of the anti-theft ring 10 at least partially overlap. At least one slot 4201 is provided on the side wall of the limiting plate 42 near the positioning plate 41. When the flip cover 20 is flipped, the positioning plate 41 is flipped and abuts against the limiting plate 42 or the anti-theft ring 10, or the end portion of the positioning plate 41 extends into the slot 4201.

[0026] In this invention, the anti-theft ring 10 is rotatably mounted on the bottle body and can prevent it from detaching from the bottle body. The flip cover 20 is mounted on the bottle body by screwing and can be rotated upward and then flipped off (opened) from the bottle body, or flipped closed onto the bottle body and then rotated downward and screwed onto the bottle body. During this process, the anti-theft ring 10 only rotates, and the flip cover 20 moves upward or downward while rotating. Therefore, the connecting rib 30 with elasticity can ensure that the flip cover 20 is always connected to the anti-theft ring 10 to avoid separation, and the upward or downward movement of the flip cover 20 can also be ensured by the elasticity. As the flip cap 20 moves upward and flips to open the bottle, its positioning plate 41 also flips after abutting against the limiting plate 42. During the flipping process of the positioning plate 41, its end can be engaged in the slot 4201 on the limiting plate 42. The engagement between the two can restrict the flipping action of the flip cap 20 without external force, that is, the flip cap 20 cannot continue to flip at a large angle, nor can it flip in the opposite direction and fasten to the bottle. The flip cap 20 is positioned in a fixed position, which can be positioned without pressing with fingers, making it convenient to use. When the flip cap 20 continues to flip at a large angle until the positioning plate 41 and the limiting plate 42 are in a parallel state, the positioning plate 41 does not interact with the slot 4201, but abuts against the body of the limiting plate 42 or the outer wall of the anti-theft ring 10. The flip cap 20 can be positioned at this position through the combined action of engagement / abutment and friction. The positioning of the positioning plate 41 at different positions can realize the positioning of the flip cap 20 at different flipping angles. Moreover, during the flip-top positioning process of the aforementioned flip-top 20, the positioning of the flip-top 20 is achieved solely through the contact action between the positioning plate 41 and the components (limiting plate 42 or anti-theft ring 10) on the integrated bottle cap. Especially when flipped at a certain angle rather than 180°, there is no need for the positioning plate 41 to engage with the bottle neck, threads, or other structures on the bottle body. In particular, the end of the positioning plate 41 and the slot 4201 on the limiting plate 42 can engage more precisely and in a matching manner. Therefore, there is no need to design the length and other parameters of the positioning plate 41 to conform to the bottle neck, threads, or other structures of different bottles. The engagement and positioning function inside the integrated bottle cap itself allows the integrated bottle cap to be applied to different bottles, thus having a wider range of applications.

[0027] Preferably, the connecting rib 30 includes a connecting portion 31 and an extension portion 32 with an integrally formed structure. The connecting portion 31 has an L-shaped structure, and the extension portion 32 has a bent structure, such as a wave-shaped structure, which can realize the telescopic function. A pair of connecting portions 31 are respectively disposed at opposite ends of the extension portion 32. The other end of one connecting portion 31 is connected to the anti-theft ring 10, and the other end of the other connecting portion 31 is connected to the flip cover 20. The connecting portion 31 with the L-shaped structure forms a large-area connection with the anti-theft ring 10 or the flip cover 20 on one side, which has good connection strength. The other side is connected to the extension portion 32. During the upward movement of the flip cover 20, the extension portion 32 provides telescopic performance. The connecting portion 31 has good connection strength with the anti-theft ring 10 or the flip cover 20 under continuous pulling. Therefore, the breakage of the connecting rib 30 itself and the connection between the connecting rib 30 and the outside can be avoided, thereby improving the service life of the connecting rib 30.

[0028] Furthermore, there are two connecting ribs 30, which are located on opposite sides of the positioning plate 41. The two connecting ribs 30 can ensure service life on the one hand, and ensure the stability and balance of the connection between the flip cover 20 and the anti-theft ring 10 on the other hand.

[0029] The upper surface of the clearance notch 200a has an arc-shaped structure, and its middle position is higher than its two ends. The anti-theft ring 10 is provided with support blocks 50 at both ends of the clearance notch 200a. The upper arc surface of the support block 50 matches the lower arc surface of the clearance notch 200a. In the initial stage when the flip cap 20 needs to rotate upward or in the final stage when it moves downward and is tightly screwed to the bottle body, the force can be transmitted after the upper surface of the support block 50 abuts against the lower surface of the clearance notch 200a. In this process, the force transmission can be avoided after the connecting rib 30 is subjected to a large force, which can ensure the service life of the connecting rib 30.

[0030] Preferably, the slot 4201 is horizontally inserted through the side wall of the limiting plate 42 on one side. There are two slots 4201, and the positioning plate 41 can have more abutment and positioning positions, which can realize positioning at more angles after the flip cover 20 is flipped, such as two large angle (not 180°) flip positioning.

[0031] Furthermore, the limiting plate 42 is integrally formed on the anti-theft ring 10. Specifically, the anti-theft ring 10 includes an outer ring 11 and an inner ring 12 connected to the outer ring 11 and located inside the outer ring 11 after being bent at 180°. The upper end of the inner ring 12 forms a limiting surface 100. The limiting plate 42 is formed on the limiting surface 100. The limiting surface 100 is used to engage with the corresponding structure on the bottle to prevent the anti-theft ring 10 from detaching from the bottle. After injection molding of the integrated bottle cap, its initial injection-molded structure is as follows: the inner ring 12 is connected to the lower end of the outer ring 11 and extends downward, and the limiting plate 42 is connected to the lower end of the inner ring 12 and extends downward. In the subsequent processing and molding process, by rotating the inner ring 12 180° relative to the outer ring 11, the end of the inner ring 12 with the limiting plate 42 is flipped and located inside the outer ring 11. The limiting surface 100 is located on the upper end surface of the inner ring 12. The limiting plate 42 is formed inside the flip cap 20 and is adjacent to the positioning plate 41.

[0032] Specifically, the limiting plate 42 includes a support portion 421 connected to the inner ring 12 and an abutment portion 422 disposed on the support portion 421 away from the inner ring 12. The slot 4201 is formed on the side wall of the abutment portion 422 near the positioning plate 41. There is a clearance slope 4220 between the support portion 421 and the abutment portion 422. The support portion 421 has a relatively thin structure. On the one hand, it cannot occupy a large area of ​​the limiting surface 100. On the other hand, its thin structure and the presence of the clearance slope 4220 can make way for the corresponding structure on the bottle so that the anti-theft ring 10 can be fitted on the bottle.

[0033] Preferably, at least one limiting groove 4202 is provided on the side wall of the abutment portion 422 away from the positioning plate 41. The limiting groove 4202 extends horizontally through the abutment portion 422 on one side of the side wall. Preferably, the limiting groove 4202 and the slot 4201 are symmetrically arranged, with the limiting groove 4202 located behind the slot 4201. A relatively thin connecting wall is formed between the two, which allows the end of the positioning plate 41 to deform to a certain extent when it extends into the slot 4201, which is beneficial. The positioning plate 41 is stable when engaged; in addition, when the integrated bottle cap is engaged with the bottle body, it is preferable that the limiting plate 42 rotates at the lower end of the thread on the bottle body. A guide ring can be set on the bottle body below the thread, and the guide ring is embedded in the limiting groove 4202. Even if the limiting plate 42 is pushed upward by the end of the positioning plate 41, the stability of the structure and position of the limiting plate 42 can be guaranteed. The limiting plate 42 will not be dislodged or fall off due to the relatively thin structure of the support part 421, which may cause the support part 421 to break.

[0034] A limiting protrusion 121 is provided on the side wall of the inner ring 12 near the outer ring 11. The limiting protrusion 121 abuts against the outer ring 11 and provides lateral support for the inner ring 12, so that the limiting surface 100 located at the upper end of the inner ring 12 can extend in the horizontal direction to engage with the structure of the bottle. The support of the limiting protrusion 121 can prevent the inner ring 12 from getting too close to the outer ring 11.

[0035] like Figure 7 and Figure 8 As shown, the present invention also provides a bottle, including a bottle body 60 and the aforementioned multi-angle positioning flip cap. The flip cap is disposed on the bottle mouth 61 of the bottle body 60. Specifically, a limiting platform 610 is provided at the lower part of the bottle mouth 61 of the bottle body 60. The flip cap 20 is screwed onto the bottle mouth 61. The anti-theft ring 10 abuts against the lower end of the limiting platform 610 through its limiting surface 100. The limiting plate 42 abuts against the bottle mouth 61 below the thread.
