Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] The embodiments of the present invention will now be described with reference to Figures 1 to 3.

[0025] This invention provides a detachable beverage bottle cap applicable to various bottle openings, comprising: a bottle cap body 100, the bottle cap body 100 being a sleeve-shaped structure with one end open (i.e., open end 11) and the other end closed (i.e., closed end 10), the inner wall of the bottle cap body 100 near the open end 11 is provided with a variety of internal thread portions 9 of different diameters, the internal thread portions 9 being arranged sequentially from large diameter to small diameter along the direction away from the open end 11, the internal thread portions 9 of different diameters being used for threaded connection to beverage bottle openings of different diameters.

[0026] The detachable beverage bottle cap provided by the present invention has multiple internal thread portions 9 of different diameters. Each internal thread portion 9 of different diameters is used to adapt to a beverage bottle mouth of a certain diameter. Therefore, the beverage bottle cap provided by the present invention can be used for beverage bottle mouths of various diameters, and its applicability is strong.

[0027] It is understandable that the beverage bottle used in conjunction with the present invention must have a bottleneck of a certain length, especially for small-diameter beverage bottles, so that the small-diameter beverage bottle can be inserted into the opening end 11 of the bottle cap body 100 to a certain depth and then threadedly connected to the corresponding inner diameter internal thread part 9.

[0028] The detachable beverage bottle cap of this invention has multiple applications:

[0029] For example, detachable beverage bottle caps can be sold separately, allowing buyers to keep them at home for future use. Alternatively, they can be sold together with the beverage bottle, enabling manufacturers to produce caps compatible with different bottle diameters using a single cap-making process or equipment, thus reducing production costs.

[0030] In some embodiments, two different diameter internal thread portions 9 are provided. These two internal thread portions 9 are preferably suitable for 28mm and 30mm diameter beverage bottles, as these are the most common bottle sizes on the market. It is understood that in some examples, the two internal thread portions 9 can also be used for other bottle diameters, such as 26mm and 32mm.

[0031] In some embodiments, the bottle cap body 100 includes an outer bottle cap 1, a middle receiving cylinder 7, and an inner bottle cap 2. The outer bottle cap 1 has a sleeve-like structure with openings at the top and bottom. The middle receiving cylinder 7 has a sleeve-like structure with a closed bottom and an open top. The inner bottle cap 2 has a sleeve-like structure with a closed top and an open bottom. The outer diameter of the middle receiving cylinder 7 is smaller than the inner diameter of the outer bottle cap 1. An internal thread 9 is provided on the inner wall of the outer bottle cap 1. The top end of the middle receiving cylinder 7 is located inside the outer bottle cap 1 and is fixedly connected to the inner wall of the outer bottle cap 1 above the internal thread 9. The bottom end of the middle receiving cylinder 7 is located below the outer bottle cap 1. The middle receiving cylinder 7 has a discharge port 6 on its wall near the bottom. The inner bottle cap 2 is movably inserted into the outer bottle cap 1 along the axial direction. The bottom end of the inner bottle cap 2 is located inside the middle receiving cylinder 7, and the top end of the inner bottle cap 2 is located above the outer bottle cap 1. When the inner bottle cap 2 moves upward along the axial direction inside the outer bottle cap 1, it can move away from the discharge port 6. When the inner bottle cap 2 moves downward along the axial direction inside the outer bottle cap 1, it can block the discharge port 6. In other words, the wall of the inner bottle cap 2 acts as a switch valve to close or open the discharge port 6. The middle receiving cylinder 7 is used to hold food ingredients.

[0032] The bottle cap provided in this embodiment has the function of adding food additives to the beverage bottle. Specifically, before drinking the beverage, people can selectively open the outlet 6 by moving the inner bottle cap 2 upwards, so that the food additives inside the middle receiving cylinder 7 can be discharged from the outlet 6 and fall into the beverage. Of course, when people do not like this flavor of food additives, they can choose not to open the outlet 6, that is, drink the original flavor beverage or water.

[0033] In some embodiments, the outer wall of the inner bottle cap 2 and the inner wall of the outer bottle cap 1 are provided with several pairs of mutually cooperating spiral guide structures, which can convert the rotation of the inner bottle cap 2 into spiral movement along the axial direction.

[0034] This embodiment makes it easy for people to open the discharge port 6 by rotating it.

[0035] In some embodiments, each pair of helical guide structures includes a guide slider and a helically extending guide groove 3 or guide hole.

[0036] In this embodiment, the guide slider and guide groove 3 serve as the first type of spiral guide structure, and the guide slider and guide hole serve as the second type of spiral guide structure.

[0037] In some examples, either the first type of spiral guide structure or the second type of spiral guide structure can be used alone.

[0038] For example, a guide slider is provided on the outer wall of the inner bottle cap 2, and a guide groove 3 is provided on the inner wall of the outer bottle cap 1. That is, an outer slide is formed on the outer bottle cap 1.

[0039] The inner bottle cap 2 has a guide groove 3 on its outer wall and a guide slider on its inner wall. That is, an inner slide is formed on the inner bottle cap 2.

[0040] The inner bottle cap 2 has a guide slider on its outer wall, and the outer bottle cap 1 has a guide hole on its inner wall. That is, an outer slide is formed on the outer bottle cap 1.

[0041] The inner bottle cap 2 has guide holes on its outer wall, and the outer bottle cap 1 has guide sliders on its inner wall. That is, an inner slide is formed on the inner bottle cap 2.

[0042] In some examples, either the first type of spiral guide structure or the second type of spiral guide structure can be used simultaneously.

[0043] For example: the outer wall of the inner bottle cap 2 is provided with two guide sliders, and the inner wall of the outer bottle cap 1 is provided with a guide groove 3 and a guide hole. One guide slider corresponds to the guide groove 3, and the other guide slider corresponds to the guide hole.

[0044] The inner bottle cap 2 has a guide slider and a guide groove 3 on its outer wall, and the outer bottle cap 1 has a guide slider and a guide hole on its inner wall. The guide slider on the inner bottle cap 2 and the guide hole on the outer bottle cap 1 are matched, and the guide groove 3 on the inner bottle cap 2 and the guide slider on the outer bottle cap 1 are matched.

[0045] Since there are many possible implementations for this embodiment, they will not be described in detail here.

[0046] In some embodiments, the guide slider is in the shape of a long spiral.

[0047] This embodiment further improves the stability of the inner cap 2 movement.

[0048] In some embodiments, the outer cap 1 and the intermediate receiving tube 7 are integrally formed.

[0049] This embodiment improves the stability of the structure.

[0050] In some embodiments, the bottom end of the intermediate container 7 is closed by a bottom cover 5. The upper surface of the bottom cover 5 is a cone shape that is narrow at the top and wide at the bottom. The upper surface of the bottom cover 5 is provided with an annular sealing groove 8 that is connected to the lower edge of the inner bottle cap 2. That is, the lower edge of the inner bottle cap 2 is located in the annular sealing groove 8.

[0051] This embodiment improves the sealing performance when the discharge port 6 is closed, and the conical bottom cover 5 facilitates the rapid discharge of food ingredients.

[0052] In some embodiments, the outer wall of the inner cap 2 located above the outer cap 1 is constructed with anti-slip texture 4, and the outer wall of the outer cap 1 is also constructed with anti-slip texture 4.

[0053] This embodiment facilitates hand-held rotation of the outer bottle cap 1 and the inner bottle cap 2.

[0054] In some embodiments, an annular protrusion is formed on the outer wall of the inner cap 2 to form a first sealing ring that seals against the inner wall of the intermediate receiving cylinder 7, and an annular protrusion is formed on the outer wall of the intermediate receiving cylinder 7 to form a second sealing ring that seals against the inner wall of the beverage bottle opening.

[0055] This embodiment achieves a seal on the opening of the beverage bottle.

[0056] In some embodiments, the outer wall of the outer cap 1 may be cylindrical as shown in Figures 1 and 2, or it may be stepped as shown in Figure 3.

[0057] When using the beverage bottle cap provided by the present invention, the degree of opening of the outlet 6 can be controlled by controlling the degree of upward movement of the inner bottle cap 2, thereby controlling the dispensing speed. In addition, after a certain amount of dispensing, the inner bottle cap 2 can be moved downward to seal the outlet 6, thereby achieving the purpose of controlling the amount added.

[0058] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
