Technical Field

[0001] This utility model relates to the field of beverage bottle technology, specifically to a beverage bottle with a multi-layer sealing structure. Background Technology

[0002] Beverage bottles are packaging bottles for beverages. They are widely used not only for packaging carbonated drinks, drinking water, fruit juice, enzymes, and tea drinks, making them the most widely used beverage packaging today, but also for packaging in many other fields such as food, chemicals, and pharmaceuticals.

[0003] Existing patent CN213110227U discloses a beverage bottle structure, including a bottle neck, bottle body, and bottle bottom designed as a single unit from top to bottom. The upper end of the bottle neck has a bottle mouth. The bottle neck further includes a protruding thread at the lower end of the bottle mouth for engaging with the threaded cap. Below the protruding thread is a groove for locking the cap, and below the groove is a raised strip for preventing the cap from sliding down. The upper end of the bottle body has a raised anti-slip mark.

[0004] The aforementioned patents or existing beverage bottles have the following problems:

[0005] The current sealing structure of beverage bottles is based on the connection between the bottle cap and the bottle mouth. The current sealing structure of beverage bottles is simple. The sealing problem of beverage bottles directly affects the shelf life, taste and safety of the product. Poor sealing allows bacteria, air or moisture to enter. Utility Model Content

[0006] The purpose of this invention is to provide a beverage bottle with a multi-layer sealing structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a beverage bottle with a multi-seal structure, comprising a bottle body, a bottle mouth provided on the bottle body, a bottle cap connected to the bottle mouth, a sealing structure provided in the bottle mouth, the sealing structure comprising a retaining ring, a retaining ring provided on the inner side of the bottle mouth, a connecting post connected inside the bottle cap, a pressure head provided on the connecting post, and a retaining slot provided in the middle of the pressure head.

[0008] Preferably, the lower end of the pressure head is conical.

[0009] Preferably, the pressure head is divided into an upper end and a lower end by a bayonet-shaped dividing line, and the diameter of the lower pressure head is smaller than the diameter of the upper pressure head.

[0010] Preferably, the pressure head is equipped with a sealing ring, the sealing ring is elastic, and the corners of the sealing ring are rounded.

[0011] Preferably, the top surface of the retaining ring is flat, the sealing ring is pressed against the top surface of the retaining ring, and the bottom surface of the retaining ring is inclined.

[0012] Preferably, a variable piece is provided in the middle of the bottle cap, and the connecting post is connected to the variable piece.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] After the bottle cap is threaded onto the bottle neck, the pressure head will pass through the retaining ring. When the pressure head passes through the retaining ring, it will collide with the retaining ring, thus producing a knocking sound, which reminds the user that the screwing is complete. At this time, the sealing ring will be pressed tightly against the surface of the retaining ring by the pressure head to achieve a better sealing effect. This makes the sealing structure of the beverage bottle not only limited to the connection between the bottle cap and the bottle neck, but also achieves multiple sealing effects, improves the sealing performance, and prevents bacteria, air or moisture from entering due to poor sealing.

[0015] When the bottle cap is opened for the first time, the pressure head will get stuck on the retaining ring, causing the connecting column to pull down the deformation plate. The deformation plate will turn white due to deformation caused by external force. When the user opens the bottle cap for the first time, check whether the deformation plate is white to see if there are any signs that the bottle cap has been opened. Attached Figure Description

[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0022] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a beverage bottle with a multiple sealing structure, including a bottle body 1, an integrally formed bottle mouth 2 at the upper end of the bottle body 1, a bottle cap 3 threadedly connected to the bottle mouth 2, and a sealing structure 4 provided in the bottle mouth 2.

[0023] Please see Figure 1 , Figure 3 and Figure 4 This utility model provides a beverage bottle with a multiple sealing structure. The sealing structure 4 includes a retaining ring 41. The top surface of the retaining ring 41 is flat, the bottom surface of the retaining ring 41 is inclined, and the retaining ring 41 is integrally formed on the inner side of the bottle mouth 2.

[0024] The bottle cap 3 has a connecting post 42 inside. The upper and lower ends of the connecting post 42 are integrally formed with a pressure head 43. The middle part of the pressure head 43 is integrally formed with a slot 44. The pressure head 43 is divided into an upper end and a lower end with the slot 44 as the dividing line. The diameter of the lower pressure head 43 is smaller than that of the upper pressure head 43. The lower end of the lower pressure head 43 is conical, which allows the pressure head 43 to better penetrate the retaining ring 41, so that the retaining ring 41 is locked in the slot 44.

[0025] The pressure head 43 is equipped with a sealing ring 45. The sealing ring 45 is elastic and has rounded corners, so that when the pressure head 43 is inserted into the retaining ring 41, the sealing ring 45 presses better on the top surface of the retaining ring 41. The pressure-bearing sealing ring 45 can fill the space between the pressure head 43 and the retaining ring 41, as well as between the pressure head 43 and the bottle mouth 2, resulting in a better sealing effect.

[0026] A variable piece 46 is provided in the middle of the bottle cap 3. The variable piece 46 will turn white when it is deformed by external force. The connecting post 42 is connected to the variable piece 46 so that the connecting post 42 is fixed inside the bottle cap 3.

[0027] After the bottle cap 3 is threadedly connected to the bottle mouth 2, the pressure head 43 will pass into the retaining ring 41. When the pressure head 43 passes into the retaining ring 41, the pressure head 43 will be deformed under force, and then the retaining ring 41 will be locked in the retaining hole 44. At this time, the pressure head 43 will return to its original position and spring back, and collide with the retaining ring 41, thereby producing a collision sound, thus reminding the user that the screwing is complete. At this time, the sealing ring 45 will be pressed tightly against the surface of the retaining ring 41 by the pressure head 43 to achieve a better sealing effect. This makes the sealing structure of the beverage bottle not limited to the connection between the bottle cap 3 and the bottle mouth 2, so as to achieve multiple sealing effects, improve the sealing performance, and prevent bacteria, air or moisture from entering due to poor sealing.

[0028] Since the connecting post 42 is connected to the changing piece 46, and the changing piece 46 is fixed on the bottle cap 3, and when the bottle cap 3 is screwed onto the bottle mouth 2, the latch 44 will be stuck on the retaining ring 41. Therefore, when the bottle cap 3 is opened for the first time, the pressure head 43 will be stuck on the retaining ring 41 due to the latch 44 being stuck on the retaining ring 41, causing the connecting post 42 to pull down the changing piece 46. The changing piece 46 will turn white under the deformation caused by external force. When the user opens the bottle cap 3 for the first time, check whether the changing piece is white to check whether the bottle cap 3 has been opened.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
