Description

Technical Field

[0001] The utility model relates to the field of bottle caps, and particularly relates to a packaging bottle cap. Background Art

[0002] The bottle cap, as a key product for bottle container packaging, is not only used to seal the bottle, but also undertakes the important functions of anti-theft opening and safety guarantee. It is widely used in the fields of food, beverage, wine, chemical industry, pharmaceutical industry, etc. The bottle caps have diverse designs and different shapes, such as circular, annular, etc., to adapt to the sealing requirements of different bottles. Its materials mainly include tinplate, chromium-plated plate, aluminum plate, plastic, etc., and a polyvinyl chloride plastic pad is often provided inside to enhance the sealing performance. The bottle cap is tightly combined with the bottle mouth through threads, and realizes efficient sealing by using the friction force and air pressure difference generated by rotation. In daily life, the bottle cap not only plays a role in protecting the product, but its diverse uses are also reflected in the reuse of waste bottle caps, such as making drill bits, handles, etc., reflecting the combination of environmental protection and creativity.

[0003] In order to facilitate pouring out the liquid in the bottle, a spout is generally provided on the bottle cap. Tilt the bottle, and the liquid in the bottle can flow out through the spout. However, when the tilt angle of the bottle is too large, the liquid will fill the spout to form an air seal, resulting in the liquid in the bottle not flowing out. For this reason, a packaging bottle cap is proposed. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a packaging bottle cap, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A packaging bottle cap includes a bottle cap body. A safety ring is provided at the bottom of the bottle cap body. Internal threads and a sealing line are provided inside the bottle cap body. A spout assembly is provided on the bottle cap body. The spout assembly includes a spout body fixed on the bottle cap body. A sealing ring is provided inside the spout body. A hook is fixedly installed on one side of the spout body. An air vent is opened on the spout body. A sealing cover body is connected to the spout body. A first sealing plug is fixedly installed on the sealing cover body. A second sealing plug is provided on one side of the first sealing plug. An air intake mechanism is connected to the air vent. The air intake mechanism includes an air intake hose connected in the air vent. One end of the air intake hose is provided with a docking nozzle. The other end of the air intake hose is fixedly installed with a positioning ring. A barrier valve is fixedly installed inside the positioning ring. A counterweight ball is fixedly installed on the air intake hose. A floating ball is provided above the counterweight ball. The floating ball will float on the liquid surface in the bottle, and the counterweight ball will apply gravity to the floating ball.

[0007] Furthermore, a connecting band is provided between the sealing cover body and the bottle mouth body. One end of the connecting band is fixed to the bottle mouth body, and the other end of the connecting band is fixed to the sealing cover body. The sealing cover body can be placed on the bottle mouth body.

[0008] Furthermore, a positioning groove is formed in the sealing cover body, and both the first sealing plug and the second sealing plug are installed on the sealing cover body through the positioning groove.

[0009] Furthermore, the sealing cover body is installed on one side of the bottle mouth body through the connecting band. The sealing cover body restricts one side of the bottle mouth body through a hook. The first sealing plug is connected to the end of the air guide hole, and the second sealing plug is connected to the end of the bottle mouth body. When the liquid flows out through the bottle mouth body, the outside air will enter the bottle through the air guide hole.

[0010] Furthermore, the air intake mechanism further includes connecting holes formed in the floating ball and the counterweight ball. Both the floating ball and the counterweight ball are connected to the air intake hose through the connecting holes, and the floating ball and the counterweight ball are connected together. The floating ball will drive the lower end of the air intake hose to float above the liquid level in the bottle.

[0011] Furthermore, the docking nozzle is provided with threads, and the docking nozzle is connected to the air guide hole through the threads.

[0012] Furthermore, one end of the air intake hose is connected to the air guide hole through the docking nozzle, and the barrier valve is installed at the other end of the air intake hose through the positioning ring. The outside air can enter the interior of the bottle through the air intake hose.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. During use, the bottle body can be tilted. After the bottle body is tilted, the liquid in the bottle body will flow out through the bottle mouth body. When the liquid flows out through the bottle mouth body, the outside air will enter the bottle body through the air guide hole, ensuring that the liquid in the bottle body can flow out smoothly. The first sealing plug and the sealing ring are in interference fit and can still maintain the sealing state after being opened and closed multiple times. Moreover, when the sealing cover body is opened, it can be hung on the hook, which is convenient for consumers to use.

[0015] 2. The floating ball will drive the lower end of the air intake hose to float above the liquid level in the bottle body. When the lower end of the air intake hose floats above the liquid level in the bottle body, the counterweight ball will apply gravity to the floating ball, making the lower end of the air intake hose always perpendicular to the liquid level in the bottle body, preventing the liquid in the bottle body from entering the air intake hose. Moreover, the barrier valve can prevent the liquid from entering the air intake hose when the bottle body shakes. No matter how large the tilt angle of the bottle body is, it can ensure that the outside air enters the bottle body through the air intake hose, and the liquid in the bottle body can flow out smoothly at any tilting angle.

One end of the connecting belt 504 is fixed to the bottle mouth body 502, and the other end of the connecting belt 504 is fixed to the sealing cover body 507.

[0024] Specifically, during use, the bottle body can be tilted. After the bottle body is tilted, the liquid inside the bottle body will flow out through the bottle mouth body 502. When the liquid flows out through the bottle mouth body 502, the outside air will enter the bottle body through the air guide hole 503, ensuring that the liquid inside the bottle body can flow out smoothly. The first sealing plug 505 and the sealing ring 501 are interlocked and interference-sealed, and can still maintain the sealing state after being opened and closed multiple times. And when the sealing cover body 507 is opened, it can be hung on the hook 508, which is convenient for consumers to use.

[0025] As Figure 4 shown in the figure, the air intake mechanism 6 includes an air intake hose 604 connected to the air guide hole 503. A docking nozzle 605 is provided at one end of the air intake hose 604. A positioning ring 601 is fixedly installed at the other end of the air intake hose 604.

Both the floating ball 602 and the counterweight ball 603 are connected to the air intake hose 604 through the connecting hole 608, and the floating ball 602 and the counterweight ball 603 are connected together.

[0026] Specifically, the floating ball 602 will drive the lower end of the air intake hose 604 to float above the liquid level inside the bottle body. When the lower end of the air intake hose 604 floats above the liquid level inside the bottle body, the counterweight ball 603 will apply gravity to the lower end of the floating ball 602, making the lower end of the air intake hose 604 always perpendicular to the liquid level inside the bottle body, preventing the liquid inside the bottle body from entering the air intake hose 604. And the barrier valve 607 can prevent the liquid from entering the air intake hose 604 when the bottle body shakes. No matter how large the tilt angle of the bottle body is, it can ensure that the outside air enters the bottle body through the air intake hose 604, and the liquid inside the bottle body can flow out smoothly at any tilting angle.

[0027] It should be noted that the present utility model is a packaging bottle cap. During actual use, first, the bottle cap body 1 is installed on the bottle body. After that, the sealing cover body 507 can be opened. After opening the sealing cover body 507, it can be hung on the hook 508. After the sealing cover body 507 is hung on the hook 508, the bottle body can be tilted. After tilting the bottle body, the liquid in the bottle will flow out through the bottle mouth body 502. When the tilting angle of the bottle body is too large, the liquid will fill the bottle mouth body 502 to form an air seal, resulting in the liquid in the bottle not flowing out. At this time, the floating ball 602 will drive the lower end of the air inlet hose 604 to float above the liquid level in the bottle. When the lower end of the air inlet hose 604 floats above the liquid level in the bottle, the counterweight ball 603 will apply gravity to the floating ball 602, so that the lower end of the air inlet hose 604 is always perpendicular to the liquid level in the bottle, enabling the outside air to enter the air inlet hose 604 through the air guide hole 503, and then enter the bottle body through the air inlet hose 604. After the outside air enters the bottle body, the liquid in the bottle will flow out through the bottle mouth body 502, and no matter how large the tilting angle of the bottle body is, it can ensure that the outside air enters the bottle body through the air inlet hose 604, and the liquid in the bottle can flow out smoothly when tilted at any angle, which is convenient for consumers to use.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
