Abstract
Description
Technical Field
[0001] This utility model relates to the field of container bottle technology, and in particular to a screw-on piercing combination bottle cap and a beverage bottle using the combination bottle cap. Background Technology
[0002] Many products currently on the market are in solvent form and need to be mixed with a liquid before use. These products include: mixed beverages, food, pharmaceuticals, cosmetics, infant formula, nutritional supplements, nutritional products, and gels used in mixtures. While these products involve mixing solvents and solutions, the resulting mixture cannot maintain its activity, stability, effective time, or strength for an extended period. Separate packaging would allow for longer storage. This necessitates a solution that allows for separate packaging while also being convenient, easy to carry, and user-friendly.
[0003] To address the aforementioned technical issues, patent application number 2021203329340 discloses a combination bottle cap that is easy to rotate and twist to achieve puncture. When using this combination bottle cap, the pressing groove needs to be pressed, which acts on the pressing area. The first snapping device on the storage compartment separates from the first snapping device on the upper cover, so that the storage compartment is in an axially free state between the upper and lower covers. Due to the weight of the storage compartment itself, the external thread end face of the storage compartment falls on the first internal thread end face of the lower cover, and the two pairs of threads are in a quasi-engaged state. Tightening the cap is equivalent to tightening the storage compartment, and the storage compartment moves axially toward the bottle mouth, that is, the aluminum foil continuously approaches the puncture structure of the lower cover. When the sealing ring of the lower cover just seals with the first sealing ring of the storage compartment, it begins to be punctured. However, the following defects exist when using this combination bottle cap: (1) It is necessary to press the groove to separate the first snap device on the storage compartment from the first snap device on the upper cap, which is relatively troublesome to operate and requires more effort to press; (2) It cannot be guaranteed that when the external thread end face of the storage compartment falls on the first internal thread end face of the lower cap, the two pairs of threads are in a quasi-meshing state, so that the storage compartment can be turned smoothly when the cap is screwed on; (3) The upper bottle cap is generally small in diameter. When performing the twisting and piercing movement, due to the large resistance, the fingers need to exert more force on the upper bottle cap, which is more strenuous. Moreover, it is easier to slip when the fingers are sweaty, which is not conducive to quickly opening the bottle cap and piercing the seal for mixing. Utility Model Content
[0004] To address the problem in the prior art that existing combination bottle caps have high twisting resistance, making it difficult to quickly puncture the seal and open the bottle cap, this utility model proposes a screw-on puncture combination bottle cap and a beverage bottle using this combination bottle cap.
[0005] The technical solution of this utility model is: a screw-on piercing combination bottle cap, comprising a lower cap body, a piercing core tube, an upper cap body, and a rotating cup;

[0016] The rotating cup has a transparent body, and the side of the rotating cup has capacity scale lines that extend in the vertical direction.
[0017] Preferably, the lower end of the storage pipe extends inward to form a horizontally arranged annular baffle. The inner diameter of the annular baffle is larger than the diameter of the sealing plate. The annular baffle and the storage pipe are fixedly and sealed together by an annular connecting plate. The thickness of the connecting plate is smaller than the thickness of the sealing plate.
[0018] Preferably, the lower end of the core tube is angled upward to form a sharp piercing head;
[0019] A third retaining edge is fixedly arranged around the middle of the core tube. The outer diameter of the third retaining edge is larger than the inner diameter of the annular retaining edge, and the outer diameter of the third retaining edge is smaller than the inner diameter of the storage tube.
[0020] Preferably, a second dividing ring plate is fixedly provided on the inner side of the cover and surrounds the sleeve, and there is a gap between the inner side of the second dividing ring plate and the outer side of the sleeve.
[0021] The gap between the second dividing ring plate and the inner circumferential side of the cover is equal to the wall thickness of the upper port of the lower cover. The upper port of the lower cover is movably inserted into the gap between the second dividing ring plate and the inner circumferential side of the cover.
[0022] Preferably, a plurality of second limiting blocks are fixedly provided on the peripheral side of the lower cover, which are spaced apart along its circumference;
[0023] An anti-theft ring is movably fitted onto the lower cover. The anti-theft ring is located at the second limiting block. Several ribs are fixedly arranged at intervals along its circumference on the inner wall of the anti-theft ring. The ribs are inserted between two adjacent second limiting blocks. The ribs and the second limiting blocks cooperate with each other to restrict the rotation of the anti-theft ring. The upper end face of the anti-theft ring and the lower end face of the cover are fixedly connected by several spaced connecting strips.
[0024] A beverage bottle includes a bottle body and a combined bottle cap as described in any of the above claims, wherein the combined bottle cap is detachably or fixedly connected to the bottle body.
[0025] Preferably, the bottle body includes a bottle mouth located at its upper end, a first external thread is provided on the outer side of the bottle mouth, and an annular first stop is fixedly provided on the bottle mouth, the first stop being located below the first external thread;
[0026] The bottle mouth is also provided with a plurality of first limiting blocks spaced apart along its circumference. The first limiting blocks are located between the first stop and the first external thread, and the thickness of the first limiting blocks gradually decreases along the opposite direction of the first external thread.
[0027] The annular cap structure includes a first annular plate and an annular first side plate fixed at the lower outer side of the first annular plate. The inner wall of the first side plate is provided with a first internal thread that is adapted to the first external thread. The first side plate is threaded onto the bottle mouth through the mating of the first internal thread and the first external thread.
[0028] The inner wall of the first side plate is also provided with a plurality of third limiting blocks spaced apart along its circumference. The third limiting blocks are located below the first internal thread. The third limiting blocks cooperate with the first limiting blocks to restrict the counterclockwise disengagement movement of the lower cap from the bottle body.
[0029] The advantages of this utility model are as follows: the threaded connection between the upper and lower cover, the threaded connection between the upper cover and the piercing core tube, and the guide structure provided on the inner wall of the storage tube and the side wall of the core tube. The guide structure restricts the axial rotation of the core tube and guides its up-and-down movement. When the rotating cup is held by hand and rotated counterclockwise, not only can the upper and lower cover rotate relative to each other with less effort, completing the separation movement of the upper and lower cover, but it can also push the piercing core tube downward to pierce the sealing plate at the bottom of the storage core tube. This allows the liquid stored in the storage tube to enter the core tube through the through hole and flow into the bottle through the lower end of the storage tube, mixing with the liquid in the bottle. One rotation is enough to complete the separation movement of the upper and lower cover and pierce the sealing plate at the bottom of the storage tube, greatly improving the ease of operation.
[0030] Moreover, compared to rotating the lid by pinching it with your fingers, this invention uses the hand to hold the rotating cup, which is more effortless. At the same time, the rotating cup can also be used to hold the mixed liquid poured from the bottle for drinking, so that the mouth does not need to be directly held in the bottle mouth, avoiding the exchange of bacteria in the mouth with the mixed liquid in the bottle, and extending the drinking time of the mixed liquid when it is not finished in one go.

[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0050] Example 1: A screw-on piercing combination bottle cap, comprising a lower cap body 2, a piercing core tube 3, an upper cap body 4, and a rotating cup 5.
[0051] like Figure 4 and Figure 5 As shown, the lower cover 2 includes a storage tube 207 that is open at both the top and bottom and an annular cover structure that is fixedly fitted on the outside of the storage tube 207. The annular cover structure is used to fix and connect to the beverage bottle body (such as integral molding connection or hot melt welding) or to connect detachably (such as snap-fit connection or threaded connection). Since the connection method between the annular cover structure and the beverage bottle body is not a key technical point in this embodiment, this embodiment does not describe the specific connection method between the annular cover structure and the beverage bottle body. It can be selected according to the actual use requirements.
[0052] The first ring plate 201 is fixedly mounted on the storage tube 207. The bottom of the first ring plate 201 is fixedly provided with a first dividing ring plate 203. The gap between the first dividing ring plate 203 and the first side plate 202 is equal to the wall thickness of the bottle mouth 101.
[0053] The inner diameter of the first ring plate 201 is larger than the outer diameter of the storage tube 207. The top of the first ring plate 201 is fixedly provided with an insertion tube section 204 coaxially arranged with the storage tube 207. The outer circumferential surface of the insertion tube section 204 is provided with a second external thread 6.
[0054] A sealing plate 10 is provided at the lower end of the storage tube 207. To facilitate localized breakage at the connection between the sealing plate 10 and the storage tube 207 in the event of a puncture, such as... Figure 3 and Figure 6 As shown, the lower end of the storage pipe 207 extends inward to form a horizontally arranged annular flange. The inner diameter of the annular flange is larger than the diameter of the sealing plate 10. The annular flange and the storage pipe 207 are fixedly and sealed together by an annular connecting plate 11. The thickness of the connecting plate 11 is less than the thickness of the sealing plate 10. The connecting plate 11 is made of a plastic material with a certain degree of flexibility.
[0055] like Figure 8 As shown, the upper cover 4 includes a snap-on cover 401 with a lower opening and a sleeve 404 fixedly disposed inside the snap-on cover 401. The snap-on cover 401 and the sleeve 404 are coaxially arranged. The inner wall of the snap-on cover 401 is provided with a second internal thread 406 that is adapted to the second external thread 6. The snap-on cover 401 is movably sleeved on the insertion tube section 204 and is threadedly connected to the insertion tube section 204 through the second external thread 6 and the second internal thread 406.
[0056] like Figure 7 As shown, the puncture core tube 3 includes a core tube 301 that is open at both ends. A through hole 303 is provided on the side wall of the core tube 301. The outer diameter of the core tube 301 is smaller than the inner diameter of the storage tube 207. The lower end of the core tube 301 is inserted into the storage tube 207. The through hole 303 is located inside the storage tube 207. The inner wall of the storage tube 207 and the side wall of the core tube 301 are provided with mutually cooperating guide structures. The guide structures are used to restrict the axial rotation of the core tube 301 and guide the core tube 301 to move up and down.
[0057] Specifically, such as Figure 5 and Figure 7 As shown, the guide structure includes multiple guide strips 12 fixed at intervals on the inner wall of the storage pipe 207 and multiple fourth blocks 305 fixed at intervals on the peripheral side of the third stop 304. The guide strips 12 extend in the vertical direction. There is a movable gap between the outer diameter of the third stop 304 and the guide strips 12. The third stop 304 is movably inserted between two adjacent guide strips 12.
[0058] The upper outer circumferential surface of the core tube 301 is provided with a third external thread 306, and the inner surface of the sleeve 404 is provided with a third internal thread 407 that is adapted to the third external thread 306. The upper end of the core tube 301 is movably inserted into the sleeve 404 and is threadedly connected to the sleeve 404 through the third external thread 306 and the third internal thread 407. When the lower cover 2 is detached from the upper cover 4 and rotates, it can push the core tube 3 downward and pierce the sealing plate 10.
[0059] To prevent the sealing plate 10 from completely detaching from the lower cover 2 when it is punctured, such as Figure 7 As shown, the lower end of the core tube 301 is tilted upward to form a sharp piercing head 302.
[0060] To prevent the core tube 3 from being punctured and falling into the bottle body 1 from the lower end of the storage tube 207, such as Figure 2 and Figure 7 As shown, a third retaining edge 304 is fixedly arranged around the middle of the core tube 301. The outer diameter of the third retaining edge 304 is larger than the inner diameter of the annular retaining edge, and the outer diameter of the third retaining edge 304 is smaller than the inner diameter of the storage tube 207.
[0061] To further improve the sealing of the storage space formed between the storage pipe 207 and the upper cover 4 during use, such as Figure 2 and Figure 9 As shown, a second dividing ring plate 405 is fixedly provided on the inner side of the cover 401, surrounding the sleeve 404. There is a gap between the inner side of the second dividing ring plate 405 and the outer side of the sleeve 404. The gap between the second dividing ring plate 405 and the inner circumferential side of the cover 401 is equal to the wall thickness of the upper port of the lower cover 2. The upper port of the lower cover 2 is movably inserted into the gap between the second dividing ring plate 405 and the inner circumferential side of the cover 401.
[0062] To further improve the anti-theft effect after sealing, such as Figure 4 , Figure 5 , Figure 8 , Figure 9 As shown, a number of second limiting blocks 205 are fixedly provided on the circumferential side of the lower cover 2 at intervals along its circumference; an anti-theft ring 13 is movably sleeved on the lower cover 2, the anti-theft ring 13 is located at the second limiting blocks 205, a number of ribs are fixedly provided on the inner wall of the anti-theft ring 13 at intervals along its circumference, the ribs are inserted between two adjacent second limiting blocks 205, the ribs and the second limiting blocks 205 cooperate with each other to restrict the rotation of the anti-theft ring 13, and the upper end face of the anti-theft ring 13 is fixedly connected to the lower end face of the cover 401 by a number of connecting strips 14 at intervals.
[0063] To facilitate observation of the volume of liquid poured into the rotating cup 5, the rotating cup 5 is a transparent cup-shaped structure with an opening at the bottom, and the side of the rotating cup 5 is provided with a capacity scale line 501 extending in the vertical direction.
[0064] like Figure 1 and Figure 2 As shown, the rotating cup 5 is fastened to the outside of the upper cover 4 and the lower cover 2, and the rotating cup 5 is rotatably connected to the lower cover 2. A rotation blocking structure is provided between the upper cover 4 and the rotating cup 5 to prevent relative rotation between the upper cover 4 and the rotating cup 5. Specifically, the rotation blocking structure includes several second anti-slip strips 402 and a retaining plate 502. The several second anti-slip strips 402 are spaced apart along the circumference of the cover 401 on the outer peripheral side of the cover 401, and the second anti-slip strips 402 extend in the vertical direction.
[0065] Several clamping plates 502 are fixedly installed on the inner wall of the rotating cup 5 at intervals along the circumference of the rotating cup 5. The clamping plates 502 are slidably inserted between two adjacent second anti-slip strips 402 so that when the rotating cup 5 rotates, the upper cover 4 can be driven to rotate through the cooperation of the clamping plates 502 and the second anti-slip strips 402.
[0066] Working principle: When in use, hold the rotating cup 5 and rotate it counterclockwise. The rotating cup 5 drives the upper cover 4 to rotate counterclockwise through the cooperation of the clamping plate 502 and the second anti-slip strip 402. Under the thread guidance of the first external thread 102 and the second internal thread 8, the upper cover 4 moves upward relative to the lower cover 2. The connecting strip 14 between the upper cover 4 and the anti-theft ring 13 is twisted off. At the same time, under the thread guidance of the third external thread 306 and the third internal thread 407, and under the action of the fourth stop 305 and the guide strip 12, the piercing core tube 3 moves downward in a straight line relative to the upper cover 4. The sharp piercing head 302 first pierces and presses one side of the sealing plate 10, causing one side of the sealing plate 10 to break from the connecting plate 11, opening the lower port of the storage tube 207, allowing the liquid in the storage tube 207 to enter the core tube 301 through the through hole 303, thus opening the independent space between the storage tube 207, the piercing core tube 3, and the beverage bottle body.
[0067] Example 2: A beverage bottle using a screw-on piercing combination cap, such as Figure 1 , Figure 2 , Figure 3 and Figure 11 As shown, it includes the combined bottle cap and bottle body 1 described in Example 1. Both the combined bottle cap and bottle body are made of transparent plastic.
[0068] like Figure 11 As shown, the upper end of the bottle body 1 is provided with a bottle mouth 101, and the outer side of the bottle mouth 101 is provided with a first external thread 102. A first annular stop 103 is fixedly provided on the bottle mouth 101, and the first stop 103 is located below the first external thread 102. The bottle mouth 101 is also provided with a plurality of first limiting blocks 104 arranged circumferentially, the first limiting blocks 104 being located between the first stop 103 and the first external thread 102, and the thickness of the first limiting blocks 104 gradually decreases along the opposite direction of the first external thread 102.
[0069] like Figure 4 and Figure 5 As shown, the annular cover structure of the lower cover 2 includes a first annular plate 201 and an annular first side plate 202 fixedly disposed at the lower outer end of the first annular plate 201, as follows. Figure 2 As shown, the inner wall of the first side plate 202 is provided with a first internal thread 8 that is adapted to the first external thread 102. The first side plate 202 is fitted onto the bottle mouth 101 through the mating of the first internal thread 8 and the first external thread 102. The lower end of the storage tube 207 is inserted into the bottle mouth 101.
[0070] The inner wall of the first side plate 202 is also provided with a plurality of third limiting blocks 9 spaced circumferentially. The third limiting blocks 9 are triangular prism structures and are located below the first internal thread 8. The third limiting blocks 9 cooperate with the first limiting block 104 to restrict the counterclockwise disengagement movement of the lower cap 2 from the bottle body 1. In order to enable the lower cap 2 to also disengage from the bottle body 1, the thickness of the third limiting blocks 9 is generally 1mm-2mm, so that when the first side plate 202 is subjected to a large torque, the first side plate 202 and the bottle mouth 101 can undergo a certain deformation, and the limiting block 9 can pass over the first limiting block 104. The other structures of the combined bottle cap are the same as in Embodiment 1.
[0071] Working principle: In use, hold the rotating cup 5 and rotate it counterclockwise. The rotating cup 5, through the cooperation of the clamping plate 502 and the second anti-slip strip 402, drives the upper cover 4 to rotate counterclockwise. Under the thread guidance of the first external thread 102 and the second internal thread 8, the upper cover 4 moves upward relative to the lower cover 2. At the same time, under the thread guidance of the third external thread 306 and the third internal thread 407, and under the action of the fourth stop 305 and the guide strip 12, the core tube 3 is pierced and moves downward relative to the upper cover 4. The linear motion, the sharp piercing head 302 first pierces one side of the sealing plate 10, causing one side of the sealing plate 10 to break from the connecting plate 11, opening the lower port of the storage tube 207, allowing the liquid in the storage tube 207 to enter the core tube 301 through the through hole 303, and then flow into the bottle body 1 through the lower port of the storage tube 207, mixing with the liquid in the bottle body 1. After mixing is completed, the rotating cup 5 continues to rotate until the upper cover 4 separates from the lower cover 2 and the pierced core tube 3, and the mixed liquid can then be consumed.
[0072] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
