Abstract

This utility model discloses a simple ready-to-use beverage bottle cap, including an upper cap, a lower cap, and a middle cap. The middle cap has a accommodating cavity, and the lower cap is hollow. The upper cap is placed on top of the middle cap, and the lower cap is fitted onto the outside of the middle cap. The outer side of the middle cap has a first external thread, and the inner wall of the lower cap has a first internal thread. The first external thread and the first internal thread mate with each other. The outer wall of the middle cap has a thinning section located above the first external thread. The upper part of the lower cap has a limiting step, and the middle cap has a limiting surface that abuts against the limiting step. When the middle cap rotates relative to the lower cap, the lower cap pulls the middle cap downwards due to the relative action of the first external thread and the first internal thread. The limiting action of the limiting surface and the limiting step prevents the middle cap from moving downwards, causing it to break along the thinning section and allowing the solute in the accommodating cavity to flow out. The entire structure is relatively simple, facilitating production and demolding, and also saving material costs, thus reducing production costs.

Description

Technical Field

[0001] This utility model belongs to the field of beverage bottle technology, and in particular relates to a simple ready-to-use beverage bottle cap and beverage bottle. Background Technology

[0002] Commercially available beverages typically involve mixing flavorings with water, but these drinks have a short shelf life and are mostly consumed immediately after opening. To extend shelf life, many additives are added, which is detrimental to health. To address these issues, ready-to-drink beverages have emerged that separate water from the flavoring agent (solute), mixing them only when needed. Most ready-to-drink beverages place the flavoring agent in the cap. Existing ready-to-drink bottle caps use methods such as piercing a partition or sealing film to achieve this. For example, application number 202420320947.X discloses a ready-to-drink bottle cap that uses a conical piercing block to pierce the sealing layer, allowing the material inside the storage shell to flow out. This structure is relatively complex, requiring more material during production, resulting in higher production costs, and making demolding during injection molding relatively difficult. Utility Model Content

[0003] The purpose of this invention is to provide a simple, ready-to-use beverage bottle cap that can solve at least one of the above-mentioned problems.

[0004] According to one aspect of this utility model, a simple ready-to-use beverage bottle cap is provided, comprising an upper cap, a lower cap, and a middle cap. The middle cap has a receiving cavity, the lower cap is hollow, the upper cap is placed on top of the middle cap, and the lower cap is fitted onto the outside of the middle cap and located below the upper cap. The outer side of the middle cap has a first external thread, and the inner wall of the lower cap has a first internal thread. The first external thread and the first internal thread cooperate with each other. The outer wall of the middle cap has a thinning portion, the thickness of which is less than the wall thickness of the middle cap. The thinning portion is located above the first external thread. The upper part of the lower cap has a limiting step, and the middle cap has a limiting surface located above the limiting step and abutting against the limiting step.

[0005] The beneficial effects of this utility model are as follows: By providing a thinning section on the outer wall of the middle cover, the thickness is relatively small. Therefore, when the middle cover rotates relative to the lower cover, the relative action of the first external thread and the first internal thread causes the lower cover to pull the middle cover downwards. However, due to the limiting effect of the limiting surface and the limiting step, the middle cover cannot move downwards, causing it to break along the thinning section. This allows the solute in the containing cavity to flow out and mix with the liquid in the bottle, achieving the purpose of instant preparation. Thus, the entire structure is relatively simple, which facilitates mold simplification and production demolding. The entire structure of the middle and lower covers uses less material, saving material costs and reducing production costs.

[0006] In some embodiments, the side wall of the lower cover is provided with a through hole. This allows the solute flowing out of the receiving cavity to mix with the liquid inside the bottle after passing through the through hole.

[0007] In some embodiments, the lower part of the cover is provided with a threaded portion, which is located below the receiving cavity, and the first external thread is located outside the threaded portion. Thus, by providing the threaded portion, the forming of the first external thread is facilitated.

[0008] In some embodiments, a mating ring is provided on the inner side of the bottom end of the lower cover, and the first internal thread is located on the inner wall of the mating ring, which is located below the through hole. Thus, by providing a mating ring, it is convenient to open the first internal thread.

[0009] In some embodiments, the lower part of the middle cover transitions to the threaded part via a tapered portion, the inner diameter of the top of the tapered portion being larger than the inner diameter of its bottom end, and the bottom of the accommodating cavity being flush with the bottom end of the tapered portion. Thus, by providing the tapered portion, the outer diameter of the lower part of the thinned portion is relatively reduced, facilitating the outflow of the solute from the accommodating cavity after the middle cover is broken.

[0010] In some embodiments, the upper part of the lower cap is provided with a connecting portion, which is located on the outer side of the lower cap, and the inner wall of the connecting portion is provided with a second internal thread. Thus, by providing a connecting portion, the lower cap and the bottle body can be easily fitted together.

[0011] In some embodiments, the outer side of the middle cover is provided with rotating teeth, and the inner wall of the lower cover is provided with limiting teeth. The rotating teeth and limiting teeth are correspondingly arranged. One side of the rotating teeth is provided with a first guide surface, and one side of the limiting teeth is provided with a second guide surface. The first guide surface and the second guide surface are correspondingly arranged. Thus, through the cooperation of the rotating teeth and the limiting teeth, the middle cover can only rotate in one direction relative to the lower cover, and cannot rotate in the opposite direction.

[0012] In some embodiments, the upper part of the middle cover is provided with a second external thread, and the inner side of the upper cover is provided with a third internal thread. The middle cover and the upper cover are engaged through the second external thread and the third internal thread. This facilitates the engagement of the upper cover and the middle cover.

[0013] In some embodiments, the mating ring, connecting portion, and lower cover are integrally molded, while the middle cover, threaded portion, and tapered portion are integrally molded. This facilitates the processing and molding of the lower cover and middle cover.

[0014] According to one aspect of this utility model, a beverage bottle including the aforementioned simple ready-to-use beverage cap is provided, further comprising a bottle body, the bottle body including a bottle mouth, the outer side of which is provided with an external thread, and the bottle mouth engaging with a second internal thread of a connecting portion via the thread. Thus, this beverage bottle allows for the separate storage of solute and water, facilitating subsequent mixing of the solute and water, achieving a ready-to-use effect, and facilitating the preservation of the solute.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Reference Figure 4 The simple ready-to-use beverage bottle cap includes an upper cap 1, a lower cap 2, and a middle cap 3. The middle cap 3 has a cavity 4 inside. The lower cap 2 is hollow. The upper cap 1 is placed on top of the middle cap 3. The lower cap 2 is fitted on the outside of the middle cap 3 and is located below the upper cap 1. The outer side of the middle cap 3 has a first external thread 31. The inner wall of the lower cap 2 has a first internal thread 21. The first external thread 31 and the first internal thread 21 are engaged. The outer wall of the middle cap 3 has a thinning part 32. The thickness of the thinning part 32 is less than the wall thickness of the middle cap 3. The thinning part 32 is located above the first external thread 31. The upper part of the lower cap 2 has a limiting step 22. The middle cap 3 has a limiting surface 33. The limiting surface 33 is located above the limiting step 22 and abuts against the limiting step 22.

[0022] When this simple, ready-to-use beverage bottle cap can be used to hold honey or other flavorings, the following explanation uses honey as an example. When filling the bottle, first, the honey is placed into the receiving cavity 4. Then, the upper cap 1 is placed on top of the middle cap 3, and the upper cap 1 is rotated clockwise to tighten it onto the middle cap 3. Subsequently, the middle cap 3 and the upper cap 1 are inserted into the lower cap 2, so that the limiting surface 33 abuts against the limiting step 2, and the middle cap 3 is properly positioned within the lower cap 2. To improve the tightness of the fit between the outer wall of the middle cap 3 and the inner wall of the lower cap 2, a raised ridge 39 is formed on the outer wall of the middle cap 3, which serves as a seal. After the middle cap 3 is inserted into the lower cap 2, rotating the middle cap 3 causes the first internal thread 21 to initially engage with the first external thread 31.

[0023] In actual use, the outer side of the middle cover 3 is formed with rotating teeth 37, and the inner wall of the lower cover 2 is formed with limiting teeth 26. The rotating teeth 37 and the limiting teeth 26 are correspondingly arranged. A first guide surface 371 is provided on one side of the rotating teeth 37, and a second guide surface 261 is provided on one side of the limiting teeth 26. The first guide surface 371 and the second guide surface 261 are correspondingly arranged. In order to prevent the middle cover 3 from being pulled out after it is engaged with the lower cover 2, a limiting protrusion 34 is formed on the outer wall of the middle cover 3. The limiting protrusion 34 is flush with the bottom end of the rotating teeth 37. When the middle cover 3 is engaged with the lower cover 2, the limiting protrusion 34 is inserted below the limiting teeth 26. The limiting teeth 26 can play a certain limiting role on the rotating teeth, thus preventing the middle cover 3 from being pulled out to a certain extent.

[0024] Since the rotating tooth 37 has a first guide surface 371 on one side and the limiting tooth 26 has a second guide surface 261 on one side, the middle cover 3 can only rotate along the direction of the first guide surface 371 when it rotates, that is, it can only rotate clockwise, and cannot rotate counterclockwise.

[0025] When the honey in the accommodating cavity 4 needs to be mixed with the liquid in the bottle, the upper cover 1 is rotated clockwise. The upper cover 1 drives the middle cover 3 to rotate clockwise simultaneously. Since the first internal thread 21 and the first external thread 31 are engaged, the middle cover 3 is pulled downward under the guidance of the first internal thread 21. However, since the limiting step 22 limits the axial position of the middle cover, the upper part of the middle cover 3 is pushed upward under the action of the limiting step 22. As the middle cover 3 rotates, the upward and downward opposing forces formed on the middle cover 3, due to the small thickness of the thinning part 32, cause the middle cover 3 to be pulled open along the thinning part 32, so that the honey in the accommodating cavity 4 can flow out.

[0026] The thinned portion 32 and the middle cover 3 are integrally injection molded structures. The thinned portion 32 can be obtained by forming a groove on the outer wall of the middle cover 3 (e.g., Figure 2 As shown), the thickness at the groove is less than the wall thickness of other parts of the middle cover 3, so that when the upper and lower sides of the thinning part 32 are subjected to upward and downward forces respectively, the middle cover 3 can be pulled apart along the thinning part 32; in actual use, the thinning part 32 can also be in the shape of a horizontal step, that is, the upper part and the lower part of the middle cover 3 are horizontally connected through the thinning part 32 (as shown). Figure 5 As shown, the thickness at this point is relatively small. When the upper and lower sides of the thinned portion 32 are subjected to upward and downward forces respectively, the middle cover 3 can be pulled off along the thinned portion 32.

[0027] This utility model features a simple, ready-to-use beverage bottle cap. Through the threaded engagement of the middle cap and the lower cap, the middle cap can be pulled open along the thinned section 32, greatly simplifying the structure of the middle cap 3 and the lower cap 2, facilitating injection molding, and reducing the amount of injection molding material used for the middle cap and the lower cap, thus saving costs.

[0028] The side wall of the middle cover 3 is formed with multiple through holes 27. Because of the through holes 27, when the middle cover 3 is broken along the thinning part 32, the honey flowing out of the accommodating cavity can quickly flow into the bottle body through the through holes 27, realizing rapid mixing with the liquid in the bottle body.

[0029] The lower part of the middle cover 3 is formed with a threaded portion 35, which is located below the accommodating cavity 4, and the first external thread 31 is located outside the threaded portion 35.

[0030] The bottom inner side of the lower cover 2 is formed with a mating ring 23, the first internal thread 21 is located on the inner wall of the mating ring 23, and the mating ring 23 is located below the through hole 27.

[0031] The lower part of the middle cover 3 transitions to the threaded part 35 via a tapered part 36. The inner diameter of the top of the tapered part 36 is larger than the inner diameter of its bottom. The bottom of the receiving cavity 4 is flush with the bottom of the tapered part 36. Therefore, the outer diameter of the threaded part 35 is relatively small. Thus, when the middle cover 3 is pulled open along the thinning part 32, the position of the through hole 27 facilitates the rapid outflow of honey. Since the bottom of the receiving cavity 4 is flush with the bottom of the tapered part 36, it is beneficial for the honey in the receiving cavity to flow out more fully.

[0032] The upper part of the lower cover 2 is provided with a connecting part 24, which is located on the outside of the lower cover 2. The inner wall of the connecting part 24 is provided with a second internal thread 25.

[0033] The upper part of the middle cover 3 is provided with a second external thread 38, and the inner side of the upper cover 1 is provided with a third internal thread 11. The middle cover 3 and the upper cover 1 are engaged by the second external thread 38 and the third internal thread 11. When the upper cover 1 is rotated clockwise, the upper cover 1 and the middle cover 3 are tightened; when the upper cover 1 is rotated counterclockwise, the upper cover 1 can be opened to facilitate normal drinking of beverages.

[0034] The mating ring 23, connecting part 24 and lower cover 2 are integrally injection molded structures, and the middle cover 3, threaded part 35 and tapered part 36 are integrally injection molded structures.

[0035] The beverage bottle, including the aforementioned simple ready-to-use beverage bottle cap, also includes a bottle body (not shown in the figure). The bottle body is a conventional bottle body, including a bottle neck with external threads on its outer side. The bottle neck extends into the inner side of the connecting part 24 and engages with the second internal thread 25 of the connecting part 24 via threaded connection. When the bottle cap is fitted to the bottle body, it can be tightened by rotating the second internal thread 25 on the connecting part 24 and the external thread on the bottle neck, facilitating the installation of the entire bottle cap onto the bottle body.

[0036] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
