Description

Technical Field

[0001] This utility model relates to the field of bubble bottle technology, and in particular to a detachable bottle cap structure for a bubble bottle. Background Technology

[0002] Currently, most sparkling water bottles on the market (such as soda makers and sparkling water pitchers) adopt a one-piece cap design, which integrates a pressure relief valve assembly to automatically release gas when the internal pressure is too high, ensuring safe use. However, this type of one-piece cap has significant drawbacks in actual use. During long-term operation, the pressure relief valve releases gas, carrying liquid or small particles (such as fruit pulp fibers and sugar residue from fruit juices). These substances easily accumulate around the pressure relief valve and inside the cap, forming stubborn dirt. Due to the non-removable nature of the cap, users cannot thoroughly clean the internal pressure relief valve and cavity. Long-term accumulation of dirt not only affects beverage hygiene but can also cause the pressure relief valve to become clogged, reduce sealing, and even shorten the cap's lifespan.

[0003] Therefore, there is an urgent need for a bottle cap device with a detachable structure that can be quickly disassembled and assembled, allowing users to thoroughly clean the inside of the bottle cap and the pressure relief valve, thereby improving the hygiene and durability of the product. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a detachable bottle cap structure for a bubble bottle, which enables quick disassembly and assembly, and facilitates users to clean the inside of the bottle cap and the pressure relief valve.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A detachable cap structure for a bubble bottle includes a bottle body and a cap device disposed at the bottle mouth of the bottle body. The cap device is characterized in that a pressure relief valve is provided inside the cap device, the cap device includes an annular cap shell and an upper cap shell, a pressure relief space communicating with the pressure relief valve is formed between the annular cap shell and the upper cap shell, and the upper cap shell is detachably disposed on the annular cap shell.

[0007] The upper cover shell has a snap-fit ​​structure along its edge, and the inner wall of the annular cover shell has a snap-fit ​​groove that can be installed and fixed with the snap-fit ​​structure.

[0008] The buckle structure includes an extension provided below the edge of the upper cover shell, an abutment provided below the extension, and an outwardly convex arc surface formed on one side of the abutment; an inwardly concave arc surface is formed on the upper side of the buckling groove for engaging with the outwardly convex arc surface.

[0009] The upper cover is provided with side ears along its edge, and the upper side of the annular cover is provided with a notch that can mate with the side ears.

[0010] The notch has an outward-facing inclined surface.

[0011] The pressure relief valve in the bottle cap device includes a first pressure relief channel and a second pressure relief channel. A first valve body is provided in the first pressure relief channel, and a second valve body is provided in the second pressure relief channel.

[0012] The bottle cap device is provided with an air intake channel, and the upper cover is provided with an air intake nozzle that communicates with the air intake channel.

[0013] The bottle cap device is connected to the bottle body via a threaded connection on the inner side of the annular cap shell.

[0014] The beneficial effects of this utility model are:

[0015] 1. By dividing the bottle cap device into a ring-shaped cap and a removable top cap, users can quickly separate the top cap and directly clean the pressure relief valve and residue in the pressure relief space, avoiding hygiene hazards and pressure relief function failure caused by dirt accumulation.

[0016] 2. The upper cover and the annular cover adopt a snap-fit ​​structure. The extension of the snap-fit ​​part matches the arc surface of the snap-fit ​​groove, which can not only ensure the guidance during installation or disassembly, but also achieve a firm lock through elastic deformation, avoiding structural damage during disassembly. Moreover, the structure is relatively simple.

[0017] 3. The fit between the side ears and the notch provides clear installation direction indication, preventing users from misaligning and improving disassembly and assembly efficiency. Attached Figure Description

[0022] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0023] Reference Figure 1 , Figure 2 This utility model proposes a detachable cap structure for a bubble bottle, including a bottle body 3 and a cap device 1 disposed at the bottle mouth of the bottle body 3. The cap device 1 is provided with a pressure relief valve. The cap device 1 includes an annular cap shell 10 and an upper cap shell 2. A pressure relief space 14 communicating with the pressure relief valve is formed between the annular cap shell 10 and the upper cap shell 2. The upper cap shell 2 is detachably disposed on the annular cap shell 10.

[0024] The upper cover 2 has a snap-fit ​​structure 21 along its lower edge, and the inner wall of the annular cover 10 has a snap-fit ​​groove 23 that can be installed and fixed with the snap-fit ​​structure 21.

[0025] Specifically, the gas inside the bubble bottle is released into the pressure relief space 14 through the pressure relief valve, and then released to the outside through the gap between the upper cover 2 and the annular cover 10. After long-term use, dirt will accumulate in the pressure relief space 14. By dividing the bottle cap device 1 into the annular cover 10 and the removable upper cover 2, the user can quickly separate the upper cover 2 and directly clean the pressure relief valve and the residue in the pressure relief space, avoiding hygiene hazards and pressure relief function failure caused by dirt accumulation.

[0026] Reference Figure 4 The snap-fit ​​structure 21 includes an extension 210 disposed below the edge of the upper cover shell 2, an abutment 211 disposed below the extension 210, and an outwardly convex arc surface 2110 formed on one side of the abutment 211; and an inwardly concave arc surface 230 formed on the upper side of the snap-fit ​​groove 23 for engaging with the outwardly convex arc surface 2110.

[0027] Specifically, the upper cover 2 and the annular cover 10 adopt a snap-fit ​​structure. The extension 210 of the upper cover 2 cooperates with the arc surface 230 of the snap-fit ​​groove 23, which can not only ensure the guidance during installation or disassembly, but also achieve a firm lock through elastic deformation, avoiding structural damage during disassembly, and the structure is relatively simple.

[0028] Reference Figure 3 The upper cover 2 has side ears 22 along its edge, and the upper side of the annular cover 10 has a notch 15 that mates with the side ears 22. Specifically, the side ears 22 mate with the notch 15 to provide a clear installation direction indicator, prevent users from misaligning, and improve assembly and disassembly efficiency.

[0029] Reference Figure 4 An outward-facing inclined surface 150 is formed on the notch 15. The inclined surface 150 facilitates the removal of the upper cover 2. Users can easily and quickly remove the upper cover 2 by fastening the side lugs 22 on it.

[0030] Reference Figure 2The pressure relief valve in the bottle cap device 1 includes a first pressure relief channel 11 and a second pressure relief channel 12. A first valve body 110 is provided in the first pressure relief channel 11, and a second valve body 120 is provided in the second pressure relief channel 12.

[0031] Furthermore, the bottle cap device 1 of this bubble bottle is provided with a first pressure relief channel 11 and a second pressure relief channel 12. Through the staged pressure relief of the dual valve body, the redundancy protection capability in case of abnormal pressure is enhanced. The structure of the pressure relief valve is more complex than that of ordinary bubble bottle caps. Although it is easier to accumulate dirt, it can also be cleaned quickly and easily by quickly removing the upper cover shell 2 of this bottle cap device 1.

[0032] The bottle cap device 1 is provided with an air inlet channel 13, and the upper cover shell 2 is provided with an air inlet nozzle 20 that communicates with the air inlet channel 13 for connecting to an external air source.

[0033] The bottle cap device 1 is threadedly connected to the bottle body 3 via a thread located inside the annular cap shell 10. When it is necessary to clean the inside of the bottle cap device 1, the bottle cap device 1 can be separated from the bottle body relatively quickly.
