Description

Technical Field

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

[0002] The puncture-type bottle cap can drive the puncture body downwards when the top cap is opened to act on the sealing film on the bottle, cutting and tearing the sealing film. This eliminates the need to open the top cap and use external tools to cut and tear the sealing film, which can improve operational efficiency and ensure hygiene and safety.

[0003] In the prior art, such as the resealable opening device disclosed in application number 202020267031.4, a base, a piercing part, and a cap are included. When the cap is unscrewed, the piercing part is driven to move vertically in the axial direction towards the mounting surface, causing the piercing protrusion to be exposed on the mounting surface. The guide part of the cap drives the piercing part to move in the axial direction to pierce the aluminum foil layer of the packaging. However, in this prior art, the aluminum foil layer is still set on the packaging box, which means that when assembling the device with the packaging box, the aluminum foil layer needs to be sealed on the packaging box first, and then the device is installed. Moreover, after assembly, there is another layer of aluminum foil for sealing, which has a limited sealing effect. In addition, for the base and the piercing part which have a relatively high height, the piercing part may not be stable enough when it is screwed to the base with only a limited threaded section in the high state. It may also be that the unstable connection may cause the piercing part to move and accidentally touch the aluminum foil layer, affecting the sealing effect. Utility Model Content

[0004] The purpose of this utility model is to provide a puncture cap, in which aluminum foil is formed at the lower end of the bottom cap and a partition is formed in the first cavity to form a double-layer sealing structure. The multi-layer sealing design ensures absolute sealing during the storage of liquid beverages, which can prevent leakage and deterioration, and the presence of the partition can further protect the aluminum foil.

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

[0006] The bottom cover has a first cavity. The lower end of the bottom cover is provided with tin foil for sealing the lower end of the first cavity. Above the tin foil, a partition is provided within the first cavity, its sidewalls connected to the inner wall of the first cavity. The upper sidewall of the bottom cover has a first external thread, and the inner wall of the first cavity has a first internal thread.

[0007] A puncture body having a second cavity, at least one stop is provided on the inner wall of the puncture body, and a second external thread is provided on the outer wall. The puncture body is embedded in the first cavity, and the second external thread is screwed into the first internal thread.

[0008] The upper cover has a second internal thread on its inner wall and a stop bar on its top wall that matches the number of the stop blocks. The upper cover is fitted onto the bottom cover, and the second internal thread is screwed into the first external thread. The stop bar extends into the second cavity and abuts against the stop block after rotation.

[0009] As a further optimization, the bottom cover includes an integrally formed main body section, a bending section and a horizontal extension section connected sequentially from top to bottom, the tin foil is disposed at the lower end of the horizontal extension section, and the partition is integrally formed at the lower end of the main body section.

[0010] As a further optimization, the side wall of the stop bar is provided with vertically extending reinforcing ribs, which can improve the structural strength of the stop bar.

[0011] As a further optimization, one side of the stop block is provided with a groove for embedding the stop rod, and the side of the stop block away from the groove is provided with a guide surface for the stop rod to pass over after being squeezed and deformed.

[0012] As a further optimization, the first internal thread is formed in the middle of the first cavity, and the second external thread is formed in the middle of the puncture body, which can ensure the stability and balance of the puncture body during the downward movement process.

[0013] As a further optimization, the top wall of the cover is provided with an inner ring, and the upper end of the puncture body is embedded in the inner ring and abuts against the inner wall of the inner ring, which can ensure the stability of the puncture body.

[0014] As a further optimization, the puncture body includes a cylindrical section and a puncture portion formed at the lower end of the cylindrical section.

[0016] As a further optimization, the spike is an inverted cone, the upper end of which is connected to the lower end of the cylindrical section, and the cone is provided with multiple through holes penetrating its body to form the clearance opening.

[0017] As a further optimization, the partition is provided with a thinning zone in the shape of a cross, with the intersection point passing through its center, so that the partition can be cracked by the thinning zone after being punctured by the puncture body.

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

[0019] 1. Forming tin foil at the bottom of the bottom cover and forming a partition in the first cavity can form a double-layer sealing structure. The multi-layer sealing design ensures absolute sealing of liquid beverages during storage, preventing leakage and spoilage.

[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 4As shown, a puncture cap includes a bottom cap 10, a puncture body 20, and an upper cap 30. The bottom cap 10 has a first cavity 100, and the lower end of the bottom cap 10 is provided with tin foil 11 for sealing the lower end of the first cavity 100. A partition 12, with its sidewalls connected to the inner wall of the first cavity 100, is located above the tin foil 11 inside the first cavity 100. A first external thread 101 is provided on the upper sidewall of the bottom cap 10, and a first internal thread 102 is provided on the inner wall of the first cavity 100. The puncture body 20 has a second cavity 200, and the inner wall of the puncture body 20 is provided with at least... A stop block 21 is provided with a second external thread 201 on its outer wall. The piercing body 20 is embedded in the first cavity 100, with its lower end located above the partition plate 12. The second external thread 201 is screwed to the first internal thread 102. The inner wall of the upper cover 30 is provided with a second internal thread 301, and the top wall is provided with a stop bar 31 matching the number of stop blocks 21. The upper cover 30 is sleeved on the bottom cover 10, and the second internal thread 301 is screwed to the first external thread 101. The stop bar 31 extends into the second cavity 200 and rotates after being driven by the rotation of the upper cover 30, and then abuts against the stop block 21.

[0030] In this invention, the puncture cap can be used in packaging boxes such as milk cartons for holding liquid beverages. The bottom cover 10 is fixedly connected to the packaging box, and the aluminum foil set at the lower end of the bottom cover 10 can seal the outlet hole on the packaging box for the liquid beverage to flow out. When liquid beverages need to be poured out, the upper cover 30 located on the bottom cover 10 is rotated. During the rotation, the upper cover 30 rotates upward through the screw connection between the second internal thread 301 and the first external thread 101. During the rotation, the upper cover 30 drives the stop rod 31 to move together. When the stop rod 31 abuts against the stop block 21 during the movement, it pushes the stop block 21 to move it and drive the piercing body 20 to rotate. Specifically, the piercing body 20 includes a cylindrical section 210 and a piercing part 220 formed at the lower end of the cylindrical section 210. The second external thread 201 and the stop block 21 are formed on the cylindrical section 210. The piercing part 220 is provided with a clearance opening (for the liquid beverage to flow through). The clearance opening and the cylindrical section 210 are connected. The segments 210 are connected to form the second cavity 200. During the rotation, the puncture body 20 rotates downward through the screwing action of the second external thread 201 and the first internal thread 102. During the downward movement, the puncture part 220 of the puncture body 20 abuts against the partition 12 and splits (such as puncturing or cutting) the partition 12 and opens it. The puncture body 20 continues to move downward and abuts against the tin foil 11, which also splits and opens the tin foil 11, so that the first cavity 100 is connected. Until the rotating upward stop bar 31 and the rotating downward stop block 21 disengage from each other, the puncture body 20 stops moving. After the upper cover 30 is rotated to separate from the bottom cover 10, the packaging box can be tilted to allow the liquid beverage inside to flow through the bottom cover 10 and the puncture body 20 and be poured out.

[0031] This invention forms a double-layer sealing structure by forming a tin foil 11 at the lower end of the bottom cover 10 and a partition 12 in the first cavity 100. The multi-layer sealing design ensures absolute sealing of the liquid beverage during storage, preventing leakage and deterioration. Moreover, by forming the tin foil 11 at the lower end of the bottom cover 10, the subsequent packaging box assembly process can be simplified. Only the puncture cap needs to be formed at the liquid outlet of the packaging box, eliminating the need to first seal the liquid outlet of the packaging box with tin foil and then assemble the puncture cap.

[0032] In addition, due to the design requirements of the product, the bottom cover 10 has a relatively high height. For ease of use, the piercing body 20 also has a high height. A partition 12 is provided above the tin foil 11. The partition 12 can prevent the piercing body 20 located above it from directly contacting the tin foil 11 due to unstable screw connection and its own rotation and downward movement, which would cause the tin foil 11 to break.

[0033] Preferably, the bottom cover 10 includes an integrally formed main body section 110, a bent section 120, and a horizontal extension section 130 connected sequentially from top to bottom. The lower end face of the horizontal extension section 130 can form a large contact surface for connecting with the packaging box. The aluminum foil 11 is disposed on the lower end face of the horizontal extension section 130. The partition 12 is integrally formed at the lower end of the main body section 110. The structure of the bent section 120 is to extend outward and then downward to connect with the horizontal extension section 130, so that a bottom cavity 100a is formed between the aluminum foil 11 and the partition 12, which can better achieve the sealing effect and has a larger space than the upper part of the first cavity 100 to facilitate the downward movement of the partition 12 through the opening.

[0034] Furthermore, the side wall of the stop rod 31 is provided with vertically extending reinforcing ribs 311 to ensure the structural strength of the stop rod 31. One side of the stop block 21 is provided with a groove 211 for embedding the stop rod 31. When the stop rod 31 abuts against the stop block 21 and drives the stop block 21 to move, the stop rod 31 sinks into the groove 211 to ensure the stability of the position between the two and prevents it from being misaligned due to force. The side of the stop block 21 away from the groove 211 is provided with a guide surface 212 for the stop rod 31 to pass over after being squeezed and deformed. When the upper cover 30 drives the stop rod 31 to rotate in the opposite direction, the stop rod 31 passes over the guide surface 212 and then over the stop block 21, so that the stop rod 31 cannot drive the stop block 21 to move.

[0035] Furthermore, to ensure the stability and balance of the puncture body 20 during its rotation and downward movement within the first cavity 100, the first internal thread 102 is formed in the middle of the first cavity 100, and the second external thread 201 is formed in the middle of the puncture body 20. Compared to the fact that their respective thread segments are formed in the upper part of their respective bodies, when the puncture body 20 has a higher height and its thread segments are formed in the middle, there can always be a large mutual contact between the thread segments, which can ensure the stability of the movement of the lower part (puncture part 220) of the puncture body 20.

[0036] Preferably, the top wall of the cover 30 is provided with an inner ring 32, and the upper end of the puncture body 20 is embedded in the inner ring 32 and abuts against the inner wall of the inner ring 32. This can ensure the stability of the relatively tall puncture body 20 within the first cavity 100, and avoid instability that may occur due to shaking or other factors when not subjected to external forces. Moreover, based on the arrangement that the first internal thread 102 is formed in the middle of the first cavity 100 and the second external thread 201 is formed in the middle of the puncture body 20, the upper end of the puncture body 20 is further positioned within the inner ring 32, which can better ensure the stability of the puncture body 20.

[0037] In this invention, the thorn 220 includes a plurality of spikes 221, which are sequentially connected at the lower end of the cylindrical section 210. The two spikes 221 at both ends form a gap 2210 at the lower end of the cylindrical section 210. Through this design, the thorn 220 can cut the partition 12 and the tin foil 11 (the cut is circular) through the piercing and cutting action of the spikes 221. The gap 2210 can prevent the thorn 220 from contacting the partition 12 and the tin foil 11 completely and cutting them completely. This ensures that the partition 12 and the tin foil 11 are at least partially connected to the bottom cover 10, thus preventing them from falling into the packaging box and being poured out with the liquid beverage after completely detaching from the bottom cover 30.

[0038] like Figure 5 and Figure 6 As shown, in another embodiment of this utility model, the piercing part 220 is an inverted cone 222. The upper end of the cone 222 is connected to the lower end of the cylindrical section 210. The cone 222 is provided with a plurality of through holes 2220 that penetrate its body to form a clearance opening. With this design, the piercing part 220 can split the partition 12 and the tin foil 11 from the middle position through the tip of the cone 222. Liquid beverages can flow through the through holes 2220 through the piercing cap and be poured out.

[0039] Preferably, the partition 12 is provided with a thinning area 121 in a cross shape with the intersection point passing through its center. This allows the partition 12 to be broken and separated from its thinning area 121 after the cone 222 acts, but the partition 12 is still connected to the bottom cover 10. Similarly, the tin foil 11 is also broken from the center position and remains connected to the bottom cover 10.

[0040] 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.
