Description

Technical Field

[0001] This utility model relates to the field of bottle caps, specifically to a filling bottle cap and a beverage bottle. Background Technology

[0002] To enhance the appeal of beverages to different consumers, the same beverage is often offered in multiple flavors. However, the specific flavor designation of a beverage still means that consumers can only purchase one flavor, failing to satisfy their desire to choose between the original flavor and flavors with added ingredients (such as tea powder).

[0003] Some existing beverages use a method of storing ingredients in the bottle cap and adding them when drinking. However, in these beverages, the ingredients are mostly stored on the removed bottle cap, which requires tearing off the seal on the cap to add the ingredients. This is inconvenient and may result in spillage during the addition process, reducing the amount of ingredients added. If too much spillage occurs, it can affect the taste of the liquid after adding the ingredients and reduce the drinking experience. Utility Model Content

[0004] The purpose of this utility model is to provide a filling bottle cap and beverage bottle that meet consumers' drinking needs for different flavors of beverages, expand the drinking audience of single beverages, and reduce the risk of spillage during the material addition process.

[0005] The technical solution adopted by this utility model to solve the above problems is:

[0006] A filling bottle cap, comprising:

[0007] The connector is a tubular structure with openings at both ends. The side of the connector is integrally connected to a connecting part for detachable installation on the bottle mouth. There is a gap between the connecting part and the connector.

[0008] A cover is used to close the opening at the top of a connector. The cover is a hollow structure that is closed at the top and open at the bottom. The cover can be fitted onto and threaded onto the top of the connector.

[0009] The connector has a sealing film bonded to the opening at the bottom end by heat pressing. The cavity of the connector is threaded with a movable part for piercing the sealing film. The movable part is a tubular structure with openings at both ends. The threads of the movable part, the connector, and the cover are arranged in opposite directions. An extension is integrally connected to the bottom surface of the cover. When the cover is connected to the connector, the cover, the connector, and the sealing film are enclosed to form a storage cavity, and the extension is inserted from top to bottom and locked onto the movable part.

[0010] As a further limitation of this utility model, a limiting ring is integrally connected to the outer surface of the movable part, the limiting ring is located above the threaded structure on the movable part, and the height of the threaded structure on the inner side of the connecting part is less than the distance between the threaded structure on the movable part and the limiting ring.

[0011] As a further limitation of this utility model, the cavities of the upper and lower parts of the connector are both cylindrical, and the diameter of the upper cavity is greater than the diameter of the lower cavity. The height of the upper cavity of the connector is greater than the height of the lower cavity. The upper cavity and the lower cavity of the connector are connected by a connecting cavity in the shape of an inverted frustum. The threaded structure on the inner side of the connector is located in the lower cavity.

[0012] As a further limitation of this utility model, a side sealing ring is integrally connected to the inner side surface of the top of the cap and the top of the connecting part. A first inner sealing ring is provided between the side sealing ring and the extension of the cap. The first inner sealing ring is integrally connected to the bottom surface of the cap. A first receiving space for the top of the connecting part to be inserted is formed between the side sealing ring and the first inner sealing ring on the cap. A second inner sealing ring is integrally connected to the outer side surface of the connecting part at a position opposite to the side sealing ring of the connecting part. A second receiving space for the top of the bottle mouth to be inserted is formed between the side sealing ring and the second inner sealing ring on the connecting part.

[0013] As a further limitation of this utility model, an anti-theft ring is connected to the bottom edge of the cover by a connecting post. The two ends of the connecting post are integrally connected to the cover and the anti-theft ring, respectively. The longitudinal cross-section of the connecting post is trapezoidal. A retaining ring is integrally connected to the outer side of the connector. When the cover and the connector are connected, the anti-theft ring is sleeved on the connector and is located between the connecting part and the retaining ring. A protrusion that can abut against the retaining ring from bottom to top is integrally connected to the inner side of the anti-theft ring.

[0014] As a further limitation of this utility model, the side of the extension is integrally connected with a plurality of inserts arranged at equal angles around its central axis, and the inner side of the top of the movable part is integrally connected with a plurality of limiting strips arranged at equal angles around its central axis, and a slot for inserting the inserts is formed between adjacent limiting strips.

[0015] As a further limitation of this utility model, the side surfaces of both the connector and the cover are integrally connected with a plurality of protrusions arranged at equal angles around their central axes.

[0016] This utility model also provides a beverage bottle, comprising:

[0017] The bottle body is a hollow structure with an open top and a closed bottom;

[0018] The bottle cap is used to seal the opening at the top of the bottle body, and the structure of the bottle body is the same as that of the filling bottle cap described in the above technical solution.

[0019] As a further limitation of this utility model, the side of the bottle body protrudes outward to form a plurality of protrusions arranged at equal angles around its central axis, each protrusion being on the same horizontal plane, and grooves for pressing with fingers are formed between adjacent protrusions.

[0020] As a further limitation of this utility model, the cross-section of the bottle body is circular, the diameter of the bottle body gradually increases from the top to the bottom, and a chamfer structure is provided on the edge of the bottom of the bottle body.

[0021] Compared with the prior art, this utility model has the following advantages and effects:

[0022] (1) Through the structural arrangement between the connector, the cap and the movable parts, this utility model realizes the effect of adding the material stored in the cap to the liquid in the bottle during the process of opening the bottle cap (that is, unscrewing the cap from the connector). At the same time, the cap can be unscrewed off the bottle body and the liquid in the bottle without added material can be drunk directly, thereby meeting the drinking needs of consumers for different flavors of beverages, improving the flexibility of beverage drinking, and expanding the drinking objects of a single beverage.

[0023] (2) By setting the connection structure between the cap and the movable part, the present invention enables the movable part to move relative to the connector during the process of the cap being unscrewed from the connector, thereby achieving the effect of puncturing the sealing film, ensuring that the material in the storage cavity is added into the liquid in the bottle, thereby changing the taste of the liquid and reducing the risk of spillage when the material is added. Furthermore, when the cap is completely detached from the connector, it can be separated from the movable part, so that the movable part can still be located in the cavity of the connector, reducing the risk of puncture or scratch caused by the movable part being connected to the unscrewed cap.

Detailed Implementation

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0037] See Figures 1-11 This embodiment of a beverage bottle includes a bottle body 1 and a bottle cap 2. The bottle body 1 is a hollow structure with an open top and a closed bottom. The bottle cap 2 is used to close the opening at the top of the bottle body 1. The bottle cap 2 can be detachably connected to the bottle mouth 11 at the top opening of the bottle body 1.

[0038] The bottle cap 2 includes a connector 3 and a sealing cap 4. The connector 3 is a tubular structure open at both ends. A connecting part 31 is integrally connected to the side of the connector 3 for detachable installation onto the bottle mouth 11. A space 32 exists between the connecting part 31 and the connector 3. The sealing cap 4 is used to close the opening at the top of the connector 3. The sealing cap 4 is a hollow structure closed at the top and open at the bottom. The sealing cap 4 can be fitted and threaded onto the top of the connector 3. The bottom of the connector 3... A sealing film 5 is heat-pressed and bonded to the opening. A movable part 6 for piercing the sealing film 5 is threadedly connected inside the cavity of the connector 3. The movable part 6, the connector 3 and the sealing cover 4 are arranged in opposite directions. The movable part 6 is a tubular structure with openings at both ends. An extension 41 is integrally connected to the bottom surface of the sealing cover 4. When the sealing cover 4 is connected to the connector 3, the sealing cover 4, the connector 3 and the sealing film 5 are surrounded to form a storage cavity 7 and the extension 41 is inserted from top to bottom and snapped onto the movable part 6.

[0039] When the beverage bottle is unopened, the material to be added to the liquid in the bottle body 1 (such as tea powder) is stored in the storage chamber 7. When the cap 4 is screwed on, causing the cap 4 to rotate relative to the connecting member 3, the cap 4 drives the movable member 6 to rotate relative to the connecting member 3 via its upper extension 41. As the cap 4 is unscrewed from the connecting member 3, the movable member 6 moves in the opposite direction of the cap 4's movement via the threaded structure between it and the connecting member 3. This causes the movable member 6 to pierce the sealing film 5. After piercing the sealing film 5 and forming an opening, the opening on the sealing film 5 expands due to the rotation of the movable member 6 relative to the connecting member 3, allowing the material in the storage chamber 7 to fall into the liquid in the bottle body 1.

[0040] During the above process, when the threaded connection between the cover 4 and the connector 3 is released, the engagement between the extension 41 on the cover 4 and the movable part 6 is released.

[0041] In this embodiment, the connecting part 31 and the bottle mouth part 11 are connected by a threaded engagement, and the movable part 6 punctures the sealing film 5 by means of a number of sharp teeth 61 integrally connected on the bottom edge.

[0042] Since the connection between the connector 3 and the bottle mouth 11 is only threaded, the connection is not secure enough. A snap-fit ​​structure can be provided between the connector 3 and the bottle mouth 11 to improve the stability of the connection. After the connector 3 is rotated and installed on the bottle mouth 11 via the threaded structure, the connector 3 is screwed again to snap it onto the bottle mouth 11. Specifically, an integrally connected limiting ring 12 is installed on the bottle mouth 11, located directly below the threaded structure on the bottle mouth 11. Several rings are integrally connected around the connector 3 on the inner side of the connecting part 31. The abutment blocks 33 are arranged at equal angles along the central axis. The protrusion of the abutment blocks 33 on the connecting part 31 is less than the protrusion of the threaded structure on them. This reduces the impact of the abutment blocks 33 on the installation of the connector 3 on the bottle mouth 11 via the connecting part 31. The top and bottom ends of the abutment blocks 33 and the top end of the limiting ring 12 are all provided with inclined structures. This reduces the difficulty of the abutment blocks 33 moving from top to bottom to directly below the limiting ring 12 when the connector 3 is installed on the bottle mouth 11. This makes the connector 3 and the bottle mouth 11 in a snap-fit ​​state while being threadedly connected.

[0043] See Figure 1 The lower horizontal cross-section of the bottle body 1 is circular and its diameter gradually increases from the top to the bottom, so that the bottle body 1 can be shaped with a smaller top and a larger bottom, which improves the stability of the beverage bottle when placed horizontally. The bottom edge of the bottle body 1 is provided with a chamfer structure 13, which enhances the smoothness of the transition between the upper side and the bottom of the bottle body 1 and improves the visual appearance of the beverage bottle.

[0044] See Figure 1 The upper side of the bottle body 1 protrudes outward to form a number of protrusions 14 arranged at equal angles around its central axis. Each protrusion 14 is on the same horizontal plane, and grooves 15 are formed between adjacent protrusions 14 for fingers to press, which facilitates holding the bottle body 1 and improves the stability of holding it.

[0045] See Figure 2 Both the connector 3 and the cap 4 have several protrusions 21 integrally connected to their sides, arranged at equal angles around their central axes. These protrusions increase friction and ensure the effectiveness of unscrewing the connector 3 from the bottle body 1 and unscrewing the cap 4 from the connector 3.

[0046] In this embodiment, the width of the protrusion 21 on the cap 4 is greater than the width of the protrusion 21 on the connector 3, which can create a difference in appearance and improve the appearance of the beverage bottle.

[0047] See Figures 5-8An anti-theft ring 43 is connected to the bottom edge of the cover 4 via a connecting post 42. The two ends of the connecting post 42 are integrally connected to the cover 4 and the anti-theft ring 43, respectively. The longitudinal cross-section of the connecting post 42 is trapezoidal, which not only realizes the connection between the cover 4 and the anti-theft ring 43, but also reduces the difficulty of disconnecting the cover 4 and the anti-theft ring 43 when the cover 4 is turned. A retaining ring 34 is integrally connected to the outer side of the connector 3. When the cover 4 is connected to the connector 3, the anti-theft ring 43 is sleeved on the connector 3 and is located between the connecting part 31 and the retaining ring 34. A protrusion 44 that can abut against the retaining ring 34 from bottom to top is integrally connected to the inner side of the anti-theft ring 43, which increases the difficulty of the anti-theft ring 43 being detached from the connector 3 and ensures the effectiveness of the anti-theft ring 43.

[0048] In this embodiment, the top and bottom ends of the protrusion 44 and the top end of the retaining ring 34 are provided with inclined structures, which reduces the difficulty of the protrusion 44 moving from top to bottom through the retaining ring 34 and being located directly below it when the cover 4 is installed on the connector 3, so that the anti-theft ring 43 can be locked between the retaining ring 34 and the connecting part 31.

[0049] See Figures 6-8 The extension 41 has a plurality of inserts 45 integrally connected to its side surface, which are arranged at equal angles around its central axis. The inner side surface of the top of the movable part 6 has a plurality of limiting strips 62 integrally connected to its side surface, which are arranged at equal angles around its central axis. Slots 63 for inserting the inserts 45 are formed between adjacent limiting strips 62, which facilitates the switching between the extension 41 and the movable part 6 in the snap-fit ​​state and the snap-fit ​​release state, and ensures the driving of the movable part 6 by the extension 41 during the process of the cover 4 being unscrewed from the connector 3 and the separation between the two after the driving is completed.

[0050] See Figure 7 , Figure 10 Side sealing rings 81 are integrally connected to the inner surfaces of the top of the capping member 4 and the top of the connecting part 31. A first inner sealing ring 82 is provided between the side sealing ring 81 and the extension part 41 on the capping member 4. The first inner sealing ring 82 is integrally connected to the bottom surface of the capping member 4. A first receiving space 83 is formed between the side sealing ring 81 and the first inner sealing ring 82 on the capping member 4 for the top of the connecting member 3 to be inserted. A second inner sealing ring 84 is integrally connected to the outer surface of the connecting member 3 at a position opposite to the side sealing ring 81 of the connecting part 31. A second receiving space 85 is formed between the side sealing ring 81 and the second inner sealing ring 84 on the connecting member 3 for the top of the bottle mouth 11 to be inserted, thereby improving the sealing effect between the capping member 4, the connecting member 3 and the bottle body 1 in sequence.

[0051] See Figure 10The cavities at the top and bottom of the connector 3 are both cylindrical, with the diameter of the upper cavity 35 being larger than the diameter of the lower cavity 36. The height of the upper cavity 35 is greater than the height of the lower cavity 36. The upper cavity and the lower cavity of the connector 3 are connected by a connecting cavity 37 that is shaped like an inverted frustum, which can guide the bottom end of the movable part 6 into the lower cavity 36 of the connector 3. The threaded structure on the inner side of the connector 3 is located in the lower cavity.

[0052] See Figure 10 , Figure 11 A limiting ring 64 is integrally connected to the outer side of the movable part 6. The limiting ring 64 is located above the threaded structure on the movable part 6. The height of the threaded structure on the inner side of the connector 3 is less than the distance between the threaded structure on the movable part 6 and the limiting ring 64.

[0053] During the process of the movable part 6 moving vertically downward relative to the connecting part 3 driven by the extension 41 on the cap 4, when the movable part 6 pierces the sealing film 5 and moves to the bottom, the threaded connection between the connecting part 3 and the movable part 6 is released. At this time, the threaded structure on the inner side of the connecting part 3 is located between the threaded structure on the movable part 6 and the limiting ring 64, which not only restricts the movable part 6 from falling into the bottle body 1, but also restricts the movable part 6 from detaching from the connecting part 3. At the same time, since the movable part 6 can rotate freely relative to the connecting part 3 at this time, the meshing position of the threaded structure between the movable part 6 and the connecting part 3 is offset, which increases the difficulty for the two to re-enter the threaded connection state and reduces the risk that the movable part 6 may move relative to the connecting part 3 and detach from the connecting part 3 under the action of liquid and gravity in the bottle body 1 when the beverage bottle is inverted.

[0054] In this embodiment, several through holes 65 arranged at equal angles around the central axis can be opened on the side of the bottom end of the movable part 6 to increase the channel for the liquid in the bottle body 1 to enter the cavity of the connector 3.

[0055] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
