Background Art

Beverages refer to liquids that can be drunk directly or after being brewed with water in a certain proportion. They are one of the indispensable drinks in people's daily lives. There are many types of beverages, and they can be classified in different ways according to different classification standards. Packaged beverages refer to beverages that can be drunk directly and are packaged in a quantitative manner for sale. They usually include plastic bottles, glass bottles, aluminum cans, cartons and other packaging forms. Packaged beverages have the advantages of being easy to carry, store and transport, so they are very popular in modern society. However, some special beverages, such as coffee, tea, honey water, etc., are usually more suitable for drinking immediately after brewing, because directly making them into drinkable liquids for packaging and preservation may affect their taste and cause the loss of nutrients. These beverages usually require special packaging to maintain their taste and quality.

A Chinese patent with announcement number CN211076977U discloses an integrated storage bottle cap, comprising a bottle cap body, a storage bin, a hemispherical protrusion, an opener and an aluminum foil sealing film; the storage bin is arranged on the inner side of the bottle cap body; the upper end of the storage bin is integrally connected to the bottle cap body; the bottom end of the storage bin is open; the bottom end of the storage bin extends to below the bottom end of the bottle cap body; an assembly gap is arranged between the storage bin and the bottle cap body; the hemispherical protrusion is arranged on the upper end of the storage bin; the opener is arranged on the inner side of the storage bin; the upper end of the opener is integrally connected to the hemispherical protrusion; the length of the opener is slightly smaller than the length of the storage bin; and the aluminum foil sealing film is heat-sealed and connected to the bottom of the storage bin.

The above technical solution has the following defects: the bottle cap stores powdered, granular or liquid materials through a storage bin. When eating or drinking, the hemispherical protrusion above the bottle cap is pressed to drive the opener in the storage bin to press down, thereby destroying and opening the aluminum foil sealing film at the bottom of the storage bin, and then opening the material bin to inject the material into the bottle body to mix and dissolve with the liquid. However, when the aluminum foil sealing film is destroyed and opened, there is a risk that the aluminum foil sealing film accidentally falls into the bottle body, which is very likely to cause hygiene problems.

DETAILED DESCRIPTION

The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

A spin-on flip-plate bottle cap, as shown in Figures 1 and 2, includes a main bottle cap 1, a storage cap 2 and a screw cap 3, the storage cap 2 is threadedly connected to the main bottle cap 1, specifically, the outer wall of the storage cap 2 is provided with an external thread 1, the inner wall of the main bottle cap 1 is provided with an internal thread 1, the external thread 1 and the internal thread 1 are threadedly matched, the screw cap 3 is threadedly connected to the main bottle cap 1, specifically, the outer wall of the main bottle cap 1 is provided with an external thread 2, the inner wall of the screw cap 3 is provided with an internal thread 2, the external thread 2 and the internal thread 2 are threadedly matched.

The storage cap 2 cooperates with the main bottle cap 1 to form a accommodating chamber 4 for storing materials. Specifically, the storage cap 2 is hollow and through, and the storage cap 2 is located inside the main bottle cap 1. Therefore, the storage cap 2 cooperates with the main bottle cap 1 to form the accommodating chamber 4. It should be noted that when filling materials, the storage cap 2 must first be installed into the main bottle cap 1, and then the materials are filled from the upper end opening of the storage cap 2 into the accommodating chamber 4, and finally the screw cap 3 is placed on the upper end of the storage cap 2 to seal the upper end opening of the storage cap 2.

The bottom of the main bottle cap 1 is provided with a sealing flap 5 , the sealing flap 5 and the main bottle cap 1 are connected via a thin wall 8 , and a connecting block 9 is connected between the sealing flap 5 and the main bottle cap 1 .

A linkage block 6 is provided in the rotary cover 3, and a linkage protrusion 7 is provided in the storage cover 2. The rotary cover 3 can drive the storage cover 2 to rotate through the linkage block 6 and the linkage protrusion 7. Specifically, when the rotary cover 3 is rotated counterclockwise, the side wall of the linkage block 6 can abut against the side wall of the linkage protrusion 7, so that the rotary cover 3 drives the storage cover 2 to rotate counterclockwise, and under the cooperation of the external thread 2 and the internal thread 2, the storage cover 2 moves until it contacts the sealing flap 5, thereby pushing the sealing flap 5 open.

Furthermore, a sharp protrusion 13 is provided at the bottom of the storage cover 2, which contacts the sealing flap 5 through the sharp protrusion 13. Due to the small contact area, when the storage cover 2 moves and applies pressure to the sealing flap 5, the pressure is more concentrated, making it easier to push open the sealing flap 5.

It should be noted that when the storage cap 2 pushes the sealing flap open, the sealing flap 5 is separated from the main bottle cap 1 along the thin wall 8. Since a connecting block 9 is connected between the sealing flap 5 and the main bottle cap 1, the sealing flap 5 cannot be completely separated from the main bottle cap 1 under the action of the connecting block 9, thereby preventing the sealing flap 5 from falling into the bottle body after being pushed open and causing hygiene problems, thereby improving the safety and hygiene of the bottle cap.

A linkage protrusion 10 is provided inside the storage cover 2. When the rotary cover 3 is rotated clockwise, the side wall of the linkage block 6 can abut against the side wall of the linkage protrusion 10, so that the rotary cover 3 drives the storage cover 2 to rotate clockwise, and under the thread cooperation between the external thread 2 and the internal thread 2, the storage cover 2 moves and moves away from the sealing flap 5.

It should be noted that, as the screw cap 3 rotates clockwise, the outer thread 1 and the inner thread 1 are engaged with each other, and the screw cap 3 is detached from the main bottle cap 1. At this time, the upper end opening of the storage cap 2 is in an open state, and the user can drink directly.

A sealing protrusion 11 is provided inside the screw cap 3 , and the outer wall of the sealing protrusion 11 abuts against the inner wall of the main bottle cap 1 , thereby ensuring the sealing of the accommodating chamber 4 .

The bottom point of the screw cap 3 is connected with an anti-theft ring 14 , which can be separated from the screw cap 3 . The user can judge whether the bottle cap has been opened by observing the state of the anti-theft ring 14 .

The main bottle cap 1 is provided with a threaded portion 12, and the threaded portion 12 is used to be threadedly connected with the bottle mouth of the bottle body, so as to realize the connection between the bottle cap and the bottle body.

The specific embodiments described in this article are merely examples of the spirit of the utility model; technicians in the technical field to which the utility model belongs can make various modifications or additions to the described specific embodiments or replace them in a similar manner, but will not deviate from the spirit of the utility model or exceed the scope defined by the attached claims.
