Description

Technical Field

[0001] This utility model relates to a bottle cap, specifically a bottle cap with a built-in storage space. Background Technology

[0002] For example, utility model CN110002097A discloses a ready-to-use bottle cap and a bottle using the same cap. The ready-to-use bottle cap includes: a lower cap comprising a cap body and a storage cylinder with an opening at the top connected to the cap body; and an upper cap comprising a press-fit cap and a top post connected to the press-fit cap. The press-fit cap is connected to the opening of the storage cylinder, forming a storage cavity. The top post is housed within the storage cavity and faces the bottom of the storage cylinder. The bottle includes the ready-to-use bottle cap and a bottle body. The bottle body has external threads corresponding to the internal threads at the bottle mouth. The ready-to-use bottle cap and bottle body are connected via the internal and external threads. This invention adopts a novel design concept: the upper and lower caps are connected to form a storage cavity. The connection point is located on the upper surface of the lower cap, providing ample processing space to ensure a tight connection between the upper and lower caps. Furthermore, the lower cap is integrally molded, allowing for good isolation between the solute and solvent, reducing product defect rates due to seal failure.

[0003] The above structure has a problem where the top column can easily break the storage chamber when the pressing cover is accidentally pressed, because the pressing cover and the top column do not have a locking mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a bottle cap with a built-in storage space. A decorative cover is provided on the outer sleeve of the bottle cap. The decorative cover has an anti-misoperation function. By operating the decorative cover, the bottom of the storage space inside the bottle cap can be punctured, so that the beverage mixture in the storage space can automatically enter the bottle. This utility model has the characteristics of preventing accidental pressing, reasonable structure and convenient operation.

[0005] To achieve the above objectives, the following technical solution is adopted: A bottle cap with a built-in storage space includes a cap body, a storage cylinder inside the cap body, and an opening at the top of the cap body communicating with the storage cylinder. The opening extends upwards to form a connection port, a press-fit cap is located at the port of the connection port, and a downwardly extending pin is located at the bottom of the press-fit cap. The lower end of the pin is close to the bottom of the storage cylinder. A decorative cover is fitted around the outside of the connection port, and an axial limiting structure is provided between the decorative cover and the outer wall of the connection port. The axial limiting structure prevents the decorative cover from moving downwards and prevents the decorative cover from touching the press-fit cap.

[0006] The storage cylinder extends downward from the port of the connection to below the lower edge of the cover. An annular groove is formed between the outer wall of the storage cylinder and the inner wall of the cover. The inner wall of the cover is provided with internal threads.

[0007] The bottom of the storage cylinder is inverted conical, and several radially arranged easy-break grooves are provided at the bottom of the inverted conical shape. The radial easy-break grooves converge at the center of the bottom of the inverted conical shape to form a puncture opening; the lower end of the ejector pin corresponds to the puncture opening.

[0008] The axial limiting structure includes a protruding post on the outer wall of the connection port and a driving groove on the side wall of the decorative cover. When the decorative cover is fitted on the outside of the connection port, the protruding post is accommodated in the driving groove. Rotating the decorative cover causes the protruding post to slide relative to the driving groove, thereby driving the lifting and lowering of the decorative cover.

[0009] The decorative cover is also provided with an anti-theft structure, which includes an easy-tear sleeve at the bottom of the decorative cover. The easy-tear sleeve is located below the drive groove. When the decorative cover is fitted onto the connection port, the easy-tear sleeve presses against the upper end of the cover and prevents the decorative cover from moving down.

[0010] An easy-tear groove is provided on the inner wall of the decorative cover below the drive groove. The easy-tear groove includes an annular easy-tear groove and an axial easy-tear groove. The lower part of the annular easy-tear groove of the decorative cover is the easy-tear sleeve. The upper end of the axial easy-tear groove is connected to the annular easy-tear groove, and the axial easy-tear groove extends downward to the lower edge of the inner wall of the decorative cover.

[0011] A guide groove is also provided on the inner wall of the easy-tear sleeve. The guide groove is axially arranged, and the upper end of the guide groove corresponds to the lower end of the drive groove.

[0012] An easy-tear section is also provided on one side of the axial easy-tear groove along the lower edge of the decorative cover.

[0013] This invention extends the cap upwards to form a connection port, and a decorative cover is provided on the connection port sleeve. An axial limiting structure is provided between the decorative cover and the outer wall of the connection port, preventing the decorative cover from being directly pressed down to trigger the pressing cover, thus preventing accidental pressing. The decorative cover also serves as a dustproof, dirtproof, and decorative function. In addition, this invention provides an easy-tear sleeve at the bottom of the decorative cover as an anti-theft structure. Since the easy-tear sleeve is on top of the cap, the decorative cover cannot move downwards to press the pressing cover before the easy-tear sleeve is broken. Only when the easy-tear sleeve is torn off, leaving a space between the decorative cover and the top of the cap, can the decorative cover be rotated and pressed down, thereby driving the ejector pin to puncture the inverted conical part at the bottom of the storage cylinder, so that the beverage mixture in the storage cylinder automatically enters the bottle. It has the characteristics of reasonable structure and convenient operation. Attached Figure Description

Detailed Implementation

[0015] like Figure 1-5 As shown, a bottle cap with a built-in storage space includes a cap body 1, a storage cylinder 2 inside the cap body 1, an opening 11 at the top of the cap body 1 communicating with the storage cylinder 2, the opening 11 extending upward to form a connection port 3, the storage cylinder 2 extending downward from the port of the connection port to below the lower edge of the cap body 1, an annular groove 12 forming between the outer wall of the storage cylinder 2 and the inner wall of the cap body 1, and an internal thread 13 on the inner wall of the cap body 1; a press-fit cap 4 is disposed at the port of the connection port 3, and a downwardly extending ejector pin 5 is provided at the bottom of the press-fit cap 4. The lower end of the pin 5 is close to the bottom of the storage cylinder 2. The bottom of the storage cylinder 2 is inverted conical 21. Several radially arranged easy-break grooves 22 are provided at the bottom of the inverted conical 21. The radial easy-break grooves 22 converge at the center of the bottom of the inverted conical to form a puncture opening 23. The lower end of the pin 5 corresponds to the puncture opening 23. A decorative cover 6 is sleeved on the outside of the connecting port 3. An axial limiting structure is provided between the decorative cover 6 and the outer wall of the connecting port 3. The axial limiting structure can prevent the decorative cover 6 from moving downward and prevent the decorative cover 6 from touching the pressing cover 4.

[0016] The axial limiting structure includes a protruding post 31 on the outer wall of the connection port and a driving groove 61 on the side wall of the decorative cover 6. When the decorative cover 6 is fitted on the outside of the connection port 3, the protruding post 31 is accommodated in the driving groove 61. Rotating the decorative cover 6 causes the protruding post 31 to slide relative to the driving groove 61, thereby driving the decorative cover 6 to rise and fall.

[0017] The decorative cover 6 is also provided with an anti-theft structure, which includes an easy-tear groove on the inner wall of the decorative cover 6 below the drive groove. The easy-tear groove includes an annular easy-tear groove 63 and an axial easy-tear groove 64. The part below the annular easy-tear groove 63 of the decorative cover 6 is the easy-tear sleeve 62. The easy-tear sleeve 62 is located below the drive groove 61. When the decorative cover 6 is fitted onto the connection port 3, the easy-tear sleeve 62 presses against the upper end of the cover body 1 and prevents the decorative cover 6 from moving down. The upper end of the axial easy-tear groove 64 is connected to the annular easy-tear groove 63, and the axial easy-tear groove 64 extends downward to the lower edge of the inner wall of the decorative cover 6.

[0018] A guide groove 65 is also provided on the inner wall of the easy-tear sleeve 62. The guide groove 65 is axially arranged, and the upper end of the guide groove 65 corresponds to the lower end of the drive groove 61. An easy-tear part 66 is also provided on the side of the lower edge of the decorative cover 6 located in the axial easy-tear groove 64.

[0019] In use, the easy-tear sleeve 62 is torn open from the axial easy-tear groove 64 and the annular easy-tear groove 63 by the easy-tear part 66, so that the easy-tear part 66 is separated from the decorative cover 6, thus leaving a certain distance between the lower end of the decorative cover 6 and the cap. At this time, the decorative cover 6 is rotated, and the decorative cover 6 moves downward with the cooperation of the drive groove 61 and the protrusion 31, so that the decorative cover 6 presses down on the cap 4 and punctures the puncture hole 23 of the inverted cone 21 at the bottom of the storage cylinder 2 through the ejector pin 5, so that the beverage mixture in the storage cylinder will automatically enter the bottle.

[0020] This invention extends the cap upward to form a connection port, and a decorative cover is provided on the connection port. An axial limiting structure is provided between the decorative cover and the outer wall of the connection port to prevent the decorative cover from being directly pressed, thus preventing accidental pressing. At the same time, an easy-tear sleeve is provided at the bottom of the decorative cover as an anti-theft structure. Only by tearing off the easy-tear sleeve to leave space for the decorative cover to move upward can the rotating decorative cover move downward through the cooperation of the drive groove and the protrusion, thereby pressing the cap and driving the ejector pin to puncture the inverted cone-shaped part at the bottom of the storage cylinder, so that the beverage mixture in the storage cylinder automatically enters the bottle. This invention punctures the bottom of the storage cylinder by rotation, which is easy and labor-saving to operate, and the axial limiting structure is reasonable.
