Description

Technical Field

[0001] The present invention relates to a beverage bottle body structure, especially for the case where two raw materials need to be stored separately before drinking. Background Art

[0002] For some beverages, the raw materials and the solution need to be stored separately before drinking. The raw materials can be solid or liquid. To facilitate sales and use, a beverage bottle with a split structure needs to be designed to achieve separate storage and convenient mixing before drinking.

[0003] In the prior art, generally a diaphragm is provided on the beverage bottle, and the bottle body is divided into upper and lower cavities by the diaphragm. The diaphragm is punctured before drinking. For example, a screw - assembled beverage bottle cap disclosed in CN219970548U includes a cylinder body, a bottle cap, and a rotating cylinder. By using the rotating action of the bottle cap, a ratchet - type structure in which the limiting block on the rotating cylinder and the groove on the inner wall of the solvent cavity of the cylinder body can only rotate unidirectionally, and the pitch of the external thread on the upper end of the rotating cylinder and the internal thread on the inner wall of the inner bottle cap is greater than the pitch of the thread on the outer edge of the upper end of the cylinder body and the internal thread on the inner wall of the bottle cap. By unscrewing the beverage bottle cap, two different solute beverages can be automatically prepared. The defect of this structure is that it is too complex. When rotating the bottle cap, the bottle cap needs to be rotated according to a certain rule to lock the ratchet, and ordinary consumers need to learn to use it. Summary of the Invention

[0004] The purpose of the present invention is to provide a bottle body structure with simple structure and convenient use, which can complete the mixing of beverages in a relatively closed environment.

[0005] The technical solution of the present invention:

[0006] A bottle cap structure for a blended beverage, including a bottle body neck 6 and a bottle cap 1. The bottle cap 1 is matched with the bottle mouth through threads. An isolation body 8 is installed inside the bottle body neck 6. The isolation body 8 isolates an independent cavity above the bottleneck. The outer circumference of the isolation body 8 is matched with the inner wall surface of the bottle body neck 6. A push rod extending upward is provided in the center of the isolation body 8 and is inserted into an annular pushing member 3 on the bottom surface of the bottle cap 1. A stop member 2 is installed at the top of the push rod. When the stop member 2 is in a contracted state, its outer diameter is smaller than the inner diameter of the pushing member 3, and when the stop member 2 expands, its outer diameter is larger than the inner diameter of the pushing member 3.

[0007] A pressure - relief port 4 is opened in the center of the push rod, and the pressure - relief port 4 communicates with the space below the isolation body 8.

[0008] The isolation body 8 is in an overall trumpet - shaped structure. A sealing ring 9 is installed on the outer circumference of the trumpet mouth, and a limiting groove 7 is provided on the inner wall surface of the bottle body neck 6.

[0009] The stopper 2 includes a base and a backstop tooth 16. There is an installation groove at the bottom of the base, and the installation groove is nested on the ejector rod. There is a limit card slot 14 on the inner wall surface of the installation groove, and the limit card slot 14 cooperates with the locking pin or locking ring on the ejector rod.

[0010] A pressure relief head 15 is provided at the center of the lower surface of the base of the stopper 2.

[0011] The backstop teeth 16 are a plurality of cantilever structures arranged in a ring. There is an installation gap between adjacent backstop teeth 16. Under the action of an external force, the backstop teeth 16 can contract inward, and there is a step structure on the outer wall surface of the backstop teeth 16.

[0012] An unlocking ring 5 is sleeved on the ejector rod of the separator 8. The unlocking ring 5 is used to maintain the stopper 2 in a contracted state when there is no cap. The outer diameter of the unlocking ring 5 is larger than the inner diameter of the annular pushing member 3.

[0013] Hooks 10 are vertically installed along the circumferential edge of the separator 8. There is an interference fit between the limiting boss protruding outward at the upper end of the hook 10 and the neck of the bottle body.

[0014] Assembly method of the bottle cap: First, fill the beverage in the bottle body; then install the separator 8 and the stopper 2, and use the unlocking ring 5 to keep the stopper 2 in a contracted state; then put the blending material into the upper cavity of the separator 8; finally, screw on the bottle cap 1. During the process of screwing on the bottle cap 1, the unlocking ring 5 is pushed down, and the stopper 2 enters the annular pushing member 3 and remains in a contracted state.

[0015] First, unscrew the bottle cap 1. After the bottle cap 1 is unscrewed, the stopper 2 opens. Then, screw on the bottle cap 1. During the screwing process, the annular pushing member 3 gets stuck on the stopper 2 and pushes the separator 8 into the bottle body; after that, unscrew the bottle cap 1 again and the separator 8 fails.

[0016] Compared with the prior art, the advantages of the present invention are as follows:

[0017] 1. The structure is simple, the use is convenient, the manufacturing cost of the bottle body is low, and the mixing of beverages can be completed in a relatively closed environment.

[0018] 2. The mixing of the beverage in the bottle body is completed by opening and closing the bottle cap once each, and it is very easy for consumers to operate.

[0019] 3. During production, the unlocking ring is used to keep the stopper in a contracted state and cooperate with the bottle cap, and the assembly process does not affect the isolation of the two cavities. Description of the Drawings
