Description
Technical Field
[0001] This utility model belongs to the field of beverage packaging technology, specifically relating to a knob-type feeding bottle cap. Background Technology
[0002] Currently, most ready-to-drink beverages separate the ingredients and water by setting up a cavity in the bottle cap to hold the ingredients. The ingredients are stored in the cavity, and when drinking, the cavity is broken open by using the structure inside the bottle cap to let the ingredients fall into the water inside the bottle to dissolve and be shaken before drinking. However, existing methods of breaking open, such as press-type piercing, have become increasingly difficult due to the problem of piercing, and have gradually evolved into knob-type piercing.
[0003] Existing patent CN220077221U discloses a knob-type beverage bottle cap, comprising a screw-on top cap, a screw-on top post, and a storage bottom cap. The screw-on top cap and the storage bottom cap are fastened together, forming a sealed chamber for storing ingredients in the storage bottom cap. The screw-on top cap has an inner screw post with an open bottom at its center, and a flange on its outer edge that is threaded to the bottle neck. The screw-on top post includes a cylindrical tube with an open top, and the upper section of the cylindrical tube has an external thread section that engages with the inner screw post. The storage bottom cap includes a stepped cylindrical tube with an open top. The cylindrical structure, with a stepped cylindrical structure and a screw cap, has a gap reserved to accommodate the bottle opening. A bottom wall is provided at the bottom. When the screw cap is twisted open, the inner spiral column pushes the spiral top column downward to puncture the bottom. However, after promotion and feedback, this technical solution still has the following problems: the screw cap and the storage bottom cover are stuck together, and the storage bottom cover is pressed and stuck together with the bottle opening, resulting in poor sealing. When the screw cap is twisted open, the spiral top column moves downward and punctures the bottom wall, making it very easy for the beverage or stored material in the bottle to leak out from the bottle opening, causing beverage loss and poor taste. Utility Model Content
[0004] The purpose of this invention is to provide a knob-type feeding bottle cap that can ensure the sealing of beverages before the drinker consumes them.
[0005] This utility model is achieved through the following technical solution:
[0006] A knob-type feeding bottle cap includes an upper cap, a lower cap, and a striking pin, wherein the upper cap and the lower cap are connected to form a chamber for storing ingredients;
[0007] The lower cover is a cylindrical structure with an open top. The outer periphery of the lower cover is provided with a flange for fixed connection with the bottle mouth, and the top of the lower cover extends upward to provide a connector for threaded connection with the upper cover.
[0008] The firing pin includes a hollow cylindrical tube with openings at both ends, the upper section of the cylindrical tube is provided with an external thread section, and the lower end of the cylindrical tube is connected to a conical spike.
[0009] The bottom of the upper cover is connected to an anti-theft ring for engaging with the connector by rotating 135°. The center of the inner surface of the upper cover is provided with an inner spiral post with a bottom opening. The inner spiral post engages with the outer thread section. By rotating on flat ground, the striking pin is pushed downward and punctures the bottom wall of the lower cover when rotated 135°.
[0010] Preferably, the inner wall of the anti-theft ring is provided with locking teeth, and the outer periphery of the connector is provided with reverse locking teeth for engaging with the locking teeth. In the initial state, the locking teeth and the reverse locking teeth do not contact each other. When the upper cover is rotated 135° in place, the locking teeth and the reverse locking teeth engage precisely.
[0011] Preferably, the bottom wall of the lower cover has an indentation point at its center, the indentation point extends in two opposite directions to the edge of the bottom wall and forms an indentation line that divides the bottom wall into two parts, the two edges of the bottom wall have a connection point at their center, and the remaining edges are provided with indentation lines.
[0012] Furthermore, a through groove is provided on the lower part of the firing pin above the conical spike.
[0013] Preferably, a retaining platform is radially arranged on the outer periphery of the middle section of the firing pin, and a plurality of guide blocks are evenly spaced on the retaining platform. A plurality of guide grooves corresponding to the guide blocks are arranged on the axial direction of the inner wall of the lower cover.
[0014] Furthermore, a ring-shaped buckle is provided at the bottom of the guide groove.
[0015] Preferably, the inner surface of the upper cover is provided with a raised sealing ring that contacts the inner wall of the connector.
[0016] Compared with the prior art, the present invention has the following advantages:
[0017] This invention features a locking mechanism on the inner wall of the anti-theft ring and a reverse locking mechanism on the outer periphery of the connector for engaging with the locking mechanism. The ring engages precisely after the top cover is rotated 135° on flat ground. Then, by rotating the top cover again, the anti-theft ring is disconnected from the top cover, and the top cover is unscrewed. This design prevents the bottom wall from being punctured during the initial rotation of the top cover, thus preventing the contents and beverage from leaking out through the gap between the top and bottom covers and ensuring the beverage remains sealed before consumption.

[0021] The present invention will be further described in detail below with reference to specific embodiments. The description is for explanation and not limitation of the present invention.
[0022] refer to Figure 1 As shown, this utility model provides a knob-type feeding bottle cap, including an upper cover 1, a lower cover 2, and a striking pin 3. The upper cover 1 and the lower cover 2 are connected to form a storage chamber 4 for dispensing ingredients. The lower cover 2 is a cylindrical structure with an open top. The outer periphery of the lower cover 2 is provided with a flange 21 for fixed connection with the bottle mouth. The flange 21 is threaded to the bottle mouth and sealed with a sealing ring. The top of the lower cover 2 extends upward to provide a connector 22 for threaded connection with the upper cover 1. The striking pin 3 includes a hollow cylindrical tube with open ends. The upper section of the cylindrical tube is provided with an external thread section 31, and the lower end of the cylindrical tube is connected to a conical spike 32. The bottom of the upper cover 1 is connected to an anti-theft ring 11. The inner wall of the anti-theft ring 11 is provided with locking teeth. The outer periphery of the connector is radially provided with teeth that can engage with the locking teeth. The upper cover has a reversible locking tooth and a raised sealing ring on its inner surface that contacts the inner wall of the connector. The inner surface of the upper cover 1 has an inner spiral post 12 with a bottom opening at its center. The inner spiral post 12 engages with the outer thread section 31. In the initial state, the locking tooth and the reversible locking tooth are not in contact. The upper cover 1 can be rotated to push the striking pin 3 downward. When the upper cover is rotated to 135°, the conical spike 32 just punctures the bottom wall of the lower cover 2, causing the ingredients stored in the chamber 4 to fall into the bottle. At this time, the locking tooth and the reversible locking tooth are locked together. If the upper cover 1 is rotated further, the upper cover 1 and the lower cover 2 will separate. At this time, the anti-theft ring will disconnect from the upper cover 1. That is, if you want to drink, you must break the connection between the anti-theft ring and the upper cover 1, which serves as an anti-theft measure.
[0023] To make puncturing easier and the opening larger so that the ingredients can blend more easily with the water in the bottle, an indentation point is provided at the center of the bottom wall of the lower cap 2. The indentation point extends to the edge of the bottom wall in two opposite directions, forming an indentation line that divides the bottom wall into two parts. A connection point is provided at the center of the edge of the two parts of the bottom wall, and indentation lines are provided on the other edges. When the conical spike 32 moves downward to apply pressure to the indentation point, it will cause the indentation line extending to the edge to break. The connection point ensures that the bottom wall will not fall into the bottle after it breaks and contaminate the beverage inside.
[0024] The lower part of the striking pin 3 is provided with a through groove 33 above the conical spike part 32. When the conical spike part 32 at the bottom of the striking pin 3 pierces the bottom wall of the lower cover 2, the beverage can smoothly enter the chamber 4 through the through groove 33 and flow out through the striking pin 3 and the lower cover 2, making it convenient to drink. At the same time, it can also avoid the situation where there is negative pressure between the upper cover 1 and the striking pin 3, which makes it difficult for the striking pin 3 to move down and detach.
[0025] The middle section of the firing pin 3 is radially provided with a locking platform 34. Several guide blocks are evenly spaced on the locking platform 34, and several guide grooves corresponding to the guide blocks are provided on the inner wall of the lower cover 2. This can limit the firing pin 3 and ensure that by rotating the upper cover 1, the inner spiral column 12 is rotated and the firing pin 3 is pushed downward without moving in the circumferential direction. At the same horizontal position at the bottom of all guide grooves, there is an annular buckle. This ensures that after the firing pin 3 breaks through the bottom wall of the lower cover 2, the guide block will be locked in the lower part of the annular buckle to form a smooth opening. Even if the upper cover 1 is rotated again, the firing pin 3 will still be fixed in the bottle mouth with the lower cover 2 until the upper cover 1 is separated from the firing pin 3.
[0026] The outer wall of the top cap 2 is provided with anti-slip texture for easy gripping, making it convenient for drinkers to unscrew the top cap 1 from the bottle for drinking.
[0027] The assembly and use principles of this utility model are as follows:
[0028] During assembly, the inner spiral post 12 of the upper cover 1 is screwed into the outer thread section 31 of the striker 3 to assemble the upper cover 1 and the striker 3. Then, the ingredient container is inserted into the lower cover 2. The assembled upper cover 1 and striker 3 are then installed on the connector at the top of the lower cover 2. At this time, the anti-theft ring's inner wall teeth and the reverse teeth on the connector are in their initial state and do not contact each other. At the same time, the guide block on the striker 3's locking platform 34 is slidably connected to the guide groove on the inner wall of the lower cover 2. The ingredients are sealed in the chamber 4. Finally, the bottle body, which has been filled with water in advance, is prepared. The flange 21 of the lower cover 2 is connected and fixed to the bottle mouth and sealed to complete the overall assembly of the beverage bottle.
[0029] In use, by rotating the top cover 1, the top cover 1 rotates 135° on the ground, which drives the inner spiral column 12 to rotate and push the impact pin 3 downward, so that the conical spike 32 just punctures the bottom wall of the bottom cover 3. At this time, the guide block on the locking platform 34 moves down along the guide groove and just gets stuck under the ring buckle, forming a smooth opening. The locking teeth on the inner wall of the anti-theft ring and the reverse locking teeth on the connector head just engage. At this time, gently shake the bottle to mix the ingredients and water. Then continue to rotate the top cover 1 until the top cover 1 is separated from the impact pin 3 and the connector head of the bottom cover 2. The impact pin 3 and the bottom cover 2 are tightly locked and fixed on the bottle mouth, and the user can drink directly.
[0030] The above description is a further detailed explanation of the present utility model in conjunction with specific embodiments. It should not be considered that the specific implementation of the present utility model is limited to these utility models. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the protection scope of the present utility model.
