Description

Technical Field

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

[0002] For some powdered materials, they need to be sealed during transportation and storage, and then mixed with a corresponding solution for immediate use. In the prior art, such as the ready-to-use bottle cap with application number 202223159059.4, a receiving space is provided between the lower and upper caps, and a piercing element is provided between the upper cap and the milk powder placement piece. The piercing element rotates and moves downward to pierce the placement piece. The piercing element includes a guide cylinder and a piercing head, which are connected to each other by connecting rods. Adjacent connecting rods form a discharge port between the guide cylinder and the piercing head.

[0003] However, the guide cylinder has a closed structure with threads on its inner wall. This increases the amount of material used during the molding process, and the closed structure of the guide cylinder also hinders the feeding of powder into the containment space to some extent. Utility Model Content

[0004] The purpose of this utility model is to provide a rotary puncture bottle cap. The puncture component is simplified to a connection between a spiral segment and a puncture part. The spiral segment can rotate and move directly within the internal thread and be supported. The structure of the puncture component is simpler, and its cooperation with the internal thread is easier. This can reduce the material used when processing and molding the puncture component, reduce production costs, and avoid the puncture component affecting the powder feeding path.

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

[0006] A bottom cap screwed onto the bottle or bag body, the bottom cap having an internal partition for forming a powder hopper above the partition, and the upper part of the inner wall of the bottom cap having internal threads.

[0007] The piercing element includes a spiral section and a piercing portion disposed at the lower end of the spiral section. The spiral section is provided with an abutment piece. The spiral section extends at least partially into the bottom cover and is screwed into the internal thread.

[0008] The upper cover is rotatably mounted on the bottom cover. The upper cover is provided with a driving plate. The upper cover rotates to drive the driving plate to abut against the abutment plate, and drives the piercing member to rotate and move downward to pierce the partition.

[0009] As a further optimization, the abutment piece is located on the upper part of the inner wall of the spiral segment.

[0010] As a further optimization, the puncture component also includes multiple connecting plates, which connect to a pair of spiral rods arranged vertically on the spiral segment. The connecting plates can ensure the stress stability of the spiral segment.

[0011] As a further optimization, the multiple connecting plates form two strip-shaped structures that extend from top to bottom and are symmetrical to each other. The regular arrangement of the multiple connecting plates facilitates the injection molding of the piercing parts and simplifies the structure of the mold cavity.

[0012] As a further optimization, the connecting plate is flush with the inner wall of the spiral segment and has a clearance gap with the outer wall of the spiral segment.

[0013] As a further optimization, the piercing part has a conical structure and is provided with multiple through holes that penetrate its body and are connected to the central cavity of the spiral section. The channel formed by the central cavity and the through holes can prevent the piercing part from affecting the feeding path of the powder into the bottle or bag, thereby improving the feeding rate of the powder.

[0014] As a further optimization, the outer wall of the bottom cover is provided with an annular limiting groove, and the inner wall of the top cover is provided with a limiting strip. The limiting strip is embedded in the annular limiting groove to prevent the top cover from detaching from the bottom cover and to ensure the stability of the connection between the two.

[0015] As a further optimization, the outer side wall of the bottom cover and / or top cover is provided with anti-slip texture, which increases friction and facilitates rotation of the bottom cover and / or top cover.

[0016] As a further optimization, the partition and the bottom cover are integrally molded and can be integrally molded by injection molding.

[0017] As a further optimization, the bottom cover includes an interlocking anti-theft ring and a cover body.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The piercing part is simplified to a connection between a spiral section and a piercing part. The spiral section can rotate and move directly in the internal thread and be supported. The structure of the piercing part is simpler, and its fit with the internal thread is easier. This can reduce the material used when processing and forming the piercing part and reduce production costs.

[0020] 2. The central cavity and through hole on the spiral section and the piercing section respectively provide a feeding path for the powder, which can improve the powder feeding rate and avoid the piercing part affecting the powder feeding path. Attached Figure Description

[0028] 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.

[0029] like Figures 1 to 7 As shown, a rotary puncture bottle cap includes a bottom cap 10, an upper cap 20, and a puncture component 30. The bottom cap 10 is screwed onto the bottle or bag. A partition 102 is provided inside the bottom cap 10 to form a powder hopper 100 above the partition 102 for holding powder. The partition 102 and the bottom cap 10 are integrally formed. An internal thread 101 is provided on the upper part of the inner wall of the bottom cap 10, located above the partition 102. The puncture component 30 includes a spiral section 31 and a puncture component disposed on... The spiral segment 31 has a piercing part 32 at the lower end. The spiral segment 31 is provided with an abutment piece 301. The abutment piece 301 is preferably located on the upper part of the inner wall of the spiral segment 31. The spiral segment 31 extends at least partially into the bottom cover 10 and is screwed into the internal thread 101. The upper cover 20 is rotatably disposed on the bottom cover 10. The upper cover 20 is provided with a driving piece 21. The upper cover 20 rotates to drive the driving piece 21 to abut against the abutment piece 301, and drives the piercing member 30 to rotate and move downward to pierce the partition 102.

[0030] In this invention, the main body of the piercing member 30 consists of a connected spiral segment 31 and a piercing part 32. The spiral segment 31 has a threaded structure formed without the need for other structures. It is mainly composed of multiple spiral rods 311 arranged from top to bottom in series. The spiral rods 311 adjacent to each other form a threaded structure, which can be screwed onto the internal thread 101 on the bottom cover 10 to achieve relative movement between the two. The piercing part 32 is used to pierce the partition 102. When using this invention, the top cover 20 is rotated on the bottom cover 10. The top cover 20 drives the driving plate 21 to move to abut against the abutting plate 301. After being pushed by the driving plate 21, the abutting plate 301 drives the spiral segment 31 to rotate and move downward within the internal thread 101, thereby driving the piercing part 32 to move downward in the rotating state to abut against the partition 102 and pierce the partition 102 to open the powder hopper 100, allowing the material in the powder hopper 100 to fall into the bottle or bag.

[0031] The piercing part 30 of this utility model is simplified to the connection between the spiral section 31 and the piercing part 32. The spiral section 31 can rotate and move directly in the internal thread 101 and be supported. On the one hand, the structure of the piercing part 30 is simpler and its cooperation with the internal thread 101 is easier. On the other hand, it can reduce the material used when the piercing part 30 is processed and formed, and reduce the production cost.

[0032] Combination Figure 4 and Figure 5 As shown, the piercing member 30 also includes multiple connecting plates 33. The connecting plates 33 connect a pair of spiral rods 311 arranged vertically on the spiral section 31. The connection plates 33 can ensure the structural stability of the spiral section 31. In particular, during the process of the spiral section 31 driving the piercing part 32 to pierce the partition 102, the reaction force during the piercing process can be avoided from causing the spiral section 31 to deform.

[0033] Multiple connecting plates 33 form two strip structures that extend from top to bottom and are symmetrical to each other. The multiple connecting plates 33 in each strip structure have the same vertical projection, and the pair of strip structures are symmetrical. The more regular structure facilitates the overall injection molding of the piercing part 30.

[0034] Preferably, the connecting plate 33 is flush with the inner wall of the spiral section 31 and has a clearance between it and the outer wall of the spiral section 31, the clearance being used to accommodate the internal thread 101.

[0035] Furthermore, the piercing part 32 has a conical structure and is provided with multiple through holes 320 that penetrate its body and are connected to the central cavity 310 of the spiral section 31. The entire piercing part 30 forms a channel that penetrates its body through the central cavity 310 and the through holes 320. During the process of the piercing part 30 entering the powder hopper 100 and piercing the partition 102, the powder can enter the central cavity 310. After the piercing part 30 pierces the partition 102, the powder can be directly discharged into the bottle or bag through the gap between the adjacent pair of spiral rods 311 or through the through holes 320 from the central cavity 310. This avoids the conventional piercing part affecting the discharge path of the powder and improves the discharge rate of the powder.

[0036] like Figure 6 and Figure 7 As shown, the outer wall of the bottom cover 10 is provided with an annular limiting groove 11, and the outer wall of the top cover 20 is provided with a limiting strip 22. The limiting strip 22 is embedded in the annular limiting groove 21, which can prevent the top cover 20 from detaching from the bottom cover 10 during rotation.

[0037] Both the bottom cover 10 and the top cover 20 have anti-slip textures on their outer side walls. For example, the first anti-slip texture 23 on the top cover 20 helps to increase friction and enable the top cover 20 to rotate relative to the bottom cover 10, which helps to drive the piercing member 30 to move. The second anti-slip texture on the bottom cover 10 can easily open the bottle or bag. For example, the anti-theft ring 1a on the bottom cover 10 is positioned on the bottle or bag, and the second anti-slip texture is set on the cover body 1b on the bottom cover 10. After the piercing action is completed and the powder is fed into the bottle or bag, the bottle or bag can be opened by rotating the cover body 1b with the help of the second anti-slip texture to disengage it from the anti-theft ring 1a.

[0038] 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.
