Description

Technical Field

[0001] This utility model relates to the field of bottle cap technology, and in particular to a pull-ring bottle cap. Background Technology

[0002] Plastic bottles are characterized by being unbreakable and inexpensive. They are connected to bottle caps by screws, which ensures both a good connection and a good seal.

[0003] To facilitate carrying the bottle, a pull ring can be provided on the cap connected to the bottle body, allowing for easy finger insertion and extraction. In the prior art, for example, a drinking water bottle cap with application number 201620472718.5 discloses a pull ring located at the top or side of the cap; another example is an integrated pull ring bottle cap and bottle with application number 202323489809.9, which discloses a pull ring that can be placed on one side of the cap during use. In the aforementioned prior art, when a finger is inserted into the pull ring for extraction, both the pull ring and the cap are located on one side of the cap, resulting in the bottle being tilted and asymmetrical during extraction, leading to poor balance. Utility Model Content

[0004] The purpose of this utility model is to provide a pull-ring bottle cap, which is formed by bending a pair of arc segments at the connection point with the connecting segment, and connecting the pair of arc segments through the snap-fit ​​action of the snap-fit ​​head and the snap-fit ​​groove. The arc segments are kept in the position directly above the bottle cap, which is convenient for finger extraction. After the arc segments are flipped over, they are located directly above the center of the bottle cap, which is beneficial for balance during extraction.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a pull-ring bottle cap, comprising:

[0006] One-piece molded bottle cap

[0007] A pull ring integrally formed on the bottle cap includes two connecting sections and two arc-shaped sections. The two connecting sections are respectively disposed on opposite sides of the side wall of the bottle cap. The two ends of the arc-shaped sections are respectively connected to a pair of connecting sections. The two arc-shaped sections are symmetrically connected to the two connecting sections to form a ring structure. One of the two arc-shaped sections is provided with a locking head, and the other is provided with a locking groove. When the two arc-shaped sections are bent and brought close to each other, their upper ends are located above the bottle cap, and the locking head is engaged in the locking groove.

[0008] As a further optimization, the two connecting segments are located at the same height of the bottle cap; the annular structure is horizontal.

[0009] As a further optimization, there is a gap between the arc-shaped segment and the bottle cap, which facilitates bending and flipping the arc-shaped segment.

[0010] As a further optimization, a recessed area is provided on the side of the arc segment near the connecting segment.

[0011] As a further optimization, the arc-shaped segment is provided with rib grooves to ensure the structural strength of the arc-shaped segment body.

[0012] As a further optimization, both the card head and the card slot are located in the middle of the arc segment; when the arc segment is not bent, the card head is located at the upper end of the arc segment.

[0013] As a further optimization, a positioning groove is provided on the side of the card head near the arc segment, and a protrusion is provided in the card groove. When the card head is embedded in the card groove, the protrusion is embedded in the positioning groove, which can ensure the connection stability between a pair of arc segments.

[0014] As a further optimization, the bottle cap includes a bottom ring and a cap body connected to the bottom ring via a bridging mechanism, wherein the connecting segment is disposed on the cap body or the bottom ring.

[0015] As a further optimization, the connecting segment is disposed on the cover.

[0016] As a further optimization, the cover is provided with anti-slip texture, which increases friction and makes it easier to rotate and open the cover after gripping.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The connection between a pair of curved segments and the connecting segment is bent so that the pair of curved segments are connected by the snap-fit ​​action of the snap-fit ​​head and the snap-fit ​​slot. The curved segments are kept in the position directly above the bottle cap for easy finger extraction.

[0019] 2. In a specific embodiment, the card head is provided with a positioning groove, and the card groove is provided with a protrusion.

[0026] 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.

[0027] like Figures 1 to 3 As shown, a pull-ring bottle cap includes a bottle cap 10 and a pull ring 20. The bottle cap 10 is an integrally formed structure, and the pull ring 20 is integrally formed on the bottle cap 10. The pull ring 20 includes two connecting sections 21 and two arc-shaped sections 22. The two connecting sections 21 are respectively disposed on opposite sides of the side wall of the bottle cap 10. The two ends of the arc-shaped sections 22 are respectively connected to a pair of connecting sections 21. The two arc-shaped sections 22 are symmetrically connected to the two connecting sections 21 to form a ring structure. One of the two arc-shaped sections 22 is provided with a locking head 221, and the other is provided with a locking groove 222. When the two arc-shaped sections 22 are bent and brought close to each other, their upper ends are located above the bottle cap 10, and the locking head 221 is engaged in the locking groove 222 so that the two arc-shaped sections 22 remain connected.

[0028] In this invention, the two ends of the arc-shaped segment 22 are respectively connected to a pair of connecting segments 21. Initially, the pair of arc-shaped segments 22 form a ring structure surrounding the periphery of the bottle cap 10. In use, the arc-shaped segment 22 can be flipped upwards by bending the connection position between it and the connecting segment 21. After the pair of arc-shaped segments 22 are flipped towards each other, the locking head 221 on one arc-shaped segment 22 can be engaged into the locking groove 222 on the other arc-shaped segment 22, thereby causing at least a portion of the arc-shaped segments 22 to abut against each other and maintaining this abutting and connected state. After the pair of arc-shaped segments 22 abut against each other, their arc-shaped structure is similar to a vertical position and has a gap with the top of the bottle cap 10, placing them above the bottle cap 10. The bottle cap can be lifted by inserting a finger between the arc-shaped segment 22 and the bottle cap 10. Figure 6 As shown, when the bottle cap 10 is applied to the bottle body 10, the bottle body 30 can be lifted by operating the pair of interlocking arc segments 22, making the bottle body 30 easy to carry; moreover, the arc segments 22 after being bent and abutted are no longer located on the side of the bottle cap 10, making it easier to hold and unscrew the bottle cap 10.

[0029] The pull ring 20 of this invention can change its state by bending the connection between the pair of arc-shaped segments 22 and the connecting segment 21. This allows the pair of arc-shaped segments 22 to be connected by the snap-fit ​​action of the snap-fit ​​head 221 and the snap-fit ​​groove 222, ensuring that the bent arc-shaped segments 22 remain directly above the bottle cap 10 for easy finger extraction. When this pull ring bottle cap is applied to the bottle body 30, because the state and position of the pair of arc-shaped segments 22 after contact are above the center of the bottle cap 10, the bottle body 30 remains vertical when extracted by finger, maintaining balance when extracting the bottle cap 10 and the bottle body 30. Furthermore, the symmetrically arranged pair of connecting segments 21 and arc-shaped segments 22 also facilitate injection molding.

[0030] Preferably, the two connecting segments 21 are located at the same height position of the bottle cap 10, and the body of the arc segment 22 is also located at the same height position of the bottle cap 10, so that the ring structure formed between the pair of arc segments 22 is horizontal.

[0031] Furthermore, there is a gap between the arc-shaped segment 22 and the bottle cap 10, that is, the arc-shaped segment 22 does not adhere to the side wall of the bottle cap 10. This allows for easy bending of the arc-shaped segment 22 at the connecting segment 21, avoiding friction or interference caused by the adhesion between the arc-shaped segment 22 and the side wall of the bottle cap 10, which would prevent the arc-shaped segment 22 from flipping upward after bending.

[0032] Preferably, a recessed area 22a is provided on the side of the arc segment 22 near the connecting segment 21. The recessed area 22a can still achieve the connection strength between the arc segment 22 and the connecting segment 21, but the thinner structure formed by the recess can also facilitate bending at this position, and the deformation recovery effect after bending cannot overcome the snapping effect between the snap head 221 and the snap groove 222.

[0033] In addition, the arc segment 22 is provided with a rib groove 220, which can further ensure the structural strength of the arc segment 22.

[0034] Preferably, both the locking head 221 and the locking slot 222 are located in the middle of the arc-shaped segment 22. When the arc-shaped segment 22 is not bent, the locking head 221 is located at the upper end of the arc-shaped segment 22. When the two arc-shaped segments 22 flip and abut against each other, the connection is made at the uppermost position, which can ensure the stress stability at the connection position and the connection stability of the two arc-shaped segments 22.

[0035] Furthermore, a positioning groove 2211 is provided on the side of the card head 221 near the arc segment 22, and a protrusion 2221 is provided in the card groove 222. When the card head 221 is inserted into the card groove 222, the protrusion 2221 is inserted into the positioning groove 2211, which can ensure the connection stability between the head 221 and the card groove 222, prevent the two from separating, and keep the two arc segments 22 in a stable connection state.

[0036] The bottle cap 10 has a specific structure including a bottom ring 12 and a cap body 11 connected to the bottom ring 12 via a bridge 100. The connecting section 21 is provided on the cap body 11 or the bottom ring 12.

[0037] Since the cap 11 needs to detach from the bottom ring 12 after the bottle cap 10 is opened, if the pull ring 20 is placed on the bottom ring 12, it would be inconvenient to operate the cap 11 after the curved section 22 bends, flips, and abuts. Therefore, to ensure that the cap 11 can easily detach from the bottom ring 12 and that the pull ring 20 is easy to use, it is preferable to place the connecting section 21 on the cap 11. Specifically, the location of the connecting section 21 on the cap 11 is as follows: Figures 1 to 3 As shown, the connecting section 21 is located at the upper part of the cover 11. This design facilitates the bending of the arc-shaped section 22 and requires less material to form the pull ring 20; Figure 4 and Figure 5 As shown, in another embodiment, the connecting section 21 is located at the lower part of the cover 11, which requires a large amount of raw materials to form the pull ring 20, and the arc-shaped section 22 extends a large distance in the lateral direction. However, in this design, the cover 11 can be unscrewed more easily without bending the arc-shaped section 22.

[0038] In addition, the cover 11 is provided with anti-slip texture, which can increase the friction with the hand and make it easier to twist open the cover 11.

[0039] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
