Description

Technical Field

[0001] The utility model belongs to the field of bottle caps with raw material storage functions, and specifically, relates to a beverage storage cap. Background Art

[0002] Bottled beverages are popular due to their better taste. Currently, common bottled beverages are directly bottled after being processed. Compared with pure water or mineral water, beverages have higher requirements for quality preservation and need additives to delay the shelf life of bottled beverages. In addition, there are also beverage bottle caps designed to store beverage raw materials (hereinafter referred to as raw materials). Before drinking, the raw materials in the bottle cap are mixed with the water in the beverage bottle to improve the drinking taste of the beverage. Currently, the technology of setting a storage space in the beverage bottle cap to store raw materials has been studied and applied.

[0003] The beverage bottle cap is designed to have a structure that can store beverage raw materials (hereinafter referred to as raw materials). Before drinking, the raw materials in the bottle cap are mixed with the water in the beverage bottle to improve the drinking taste of the beverage. Currently, the technology of setting a storage space in the beverage bottle cap to store raw materials has been studied and applied.

[0004] The sealing of raw materials in the beverage bottle cap is usually achieved by setting a storage cavity in the beverage bottle cap and then sealing the storage cavity with an aluminum film. Before drinking, the aluminum film is punctured to achieve the mixing of raw materials and water. Storing raw materials in the beverage bottle cap not only requires the beverage bottle cap to have good sealing for raw materials to prevent the raw materials from getting damp or deteriorating, but also requires the raw materials to smoothly enter the beverage bottle and be mixed with water when drinking. Since the aluminum film has good elasticity, a certain puncturing force is required to puncture it. Moreover, due to the elasticity of the aluminum film, when the aluminum film is punctured, the aluminum film is prone to deformation and moves away from the puncturing needle. Therefore, the length of the puncturing needle needs to be ensured. The thicker the aluminum film, the greater the puncturing force required, and the greater the elastic deformation during puncturing. To ensure that the aluminum film can be smoothly punctured, current beverage bottle caps mostly achieve this by reducing the thickness of the aluminum film or reducing the sealing strength between the aluminum film and the storage cavity. However, this method will result in poor sealing effects. After long-term storage, the risks of getting damp and deteriorating increase. If the stored raw material is a liquid, it is extremely easy to leak. Therefore, current beverage bottle caps can mostly only store solid raw materials and cannot meet the storage of liquid beverage raw materials. For this problem, Patent CN220555458U provides a beverage bottle cap that can store liquid raw materials, effectively solving the above problems. However, it is still of positive significance to provide a new structure of beverage storage cap that can meet the storage of liquid raw materials, has good sealing performance, and the aluminum film is easy to puncture. Summary of the Utility Model

[0005] To overcome the problems existing in the background art, the present utility model provides a beverage storage lid which can not only store solid raw materials, but also meet the storage requirements of liquid beverages. Moreover, under the condition of obtaining a good sealing effect, the sealing film can still be effectively punctured to ensure the mixing of raw materials and water. In addition, the present utility model can also be used as a beverage storage lid, which can be covered on the beverage bottle during use, having better flexibility in use.

[0041] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", "provided with" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example 1

[0042] As Figure 1-12 shown, the beverage storage cap includes a raw material storage cylinder 1, a pressing top cover 2, and a needle 3. The raw material storage cylinder 1 includes an upper cylinder body 11, a lower cylinder body 12, and a connecting ring plate 13 connected between the upper cylinder body 11 and the lower cylinder body 12. The diameter of the upper cylinder body 11 is larger than that of the lower cylinder body 12. An upper sealing film 14 and a lower sealing film 19 are respectively provided on the upper end surface of the upper cylinder body 11 and the lower end surface of the lower cylinder body 12. The inner cavities of the upper cylinder body 11 and the lower cylinder body 12 communicate to form a raw material storage cavity. The upper and lower ends of the raw material storage cylinder 1 of the present utility model are both open, and this structure is also easy to demold during processing.

[0043] The needle 3 is arranged between the pressing top cover 2 and the upper cylinder body 11. When pressing down the pressing top cover 2, the pressing top cover 2 moves the needle 3 downward to pierce the upper sealing film 14 and the lower sealing film 19 of the raw material storage cylinder 1, and the raw material flows out from the storage cavity.

[0044] A pressing track groove 15 is provided on the outer wall of the upper cylinder body 11, and the pressing track groove 15 is formed by a rib 18 provided on the outer wall of the upper cylinder body 11. The pressing track groove 15 includes a vertical track and an upper horizontal track vertically communicating with the side of the vertical track. Two pressing track grooves 15 are symmetrically arranged. Correspondingly, two pressing limit blocks 21 matching the width and groove depth of the pressing track groove 15 are provided on the inner wall of the pressing top cover 2. The pressing top cover 2 is sleeved outside the upper cylinder body 11. After being sleeved, the pressing limit blocks 21 can move along the pressing track groove 15.

[0045] A pressing limit block passage 16 is opened at the upper end of the pressing track groove 15 to enable the pressing limit block 21 to smoothly enter the pressing track groove 15 when installing the pressing top cover 2 and the raw material storage cylinder; the pressing limit block passage 16 can also not be provided. The pressing top cover 2 is made of plastic material, and by using the elasticity of the plastic material, the pressing limit block 21 is pressed into the pressing track groove 15. Two clamping blocks 17 are provided in the vertical section of the pressing track groove 15. The clamping blocks 17 are inclined clamping blocks, which are ramp structures with a thickness increasing from top to bottom. The structure of the clamping blocks 17 enables the pressing limit block 21 to slide smoothly, and once pressed, it is limited by the clamping blocks 17 and cannot slide upward. When it is not necessary to pierce the upper sealing film 14 and the lower sealing film 19, the pressing limit block 21 is located in the horizontal section of the pressing track groove 15. When it is necessary to pierce the upper sealing film 14 and the lower sealing film 19, rotate the pressing top cover 2 and press it downward along the vertical section of the pressing track groove 15. The length of the vertical section of the pressing track groove 15 can enable the pressing top cover 2 to generate an impact force during the downward pressing process, making the upper sealing film 14 and the lower sealing film 19 easier to be pierced.

[0046] Inside the raw material storage cylinder 1, there is a needle-punching fitting 4. The needle-punching fitting 4 includes a cylinder 41 and a top cover 42 arranged at the top end of the cylinder 41. The cylinder 41 is arranged inside the raw material storage cylinder 1, and its outer diameter is smaller than that of the lower cylinder body 12. The needle-punching fitting 4 can be fixed in the raw material storage cylinder 1 through a fixing strip, or can be directly placed in the raw material storage cylinder 1. When adopting the fixing method, a connecting strip can be arranged between the outer wall of the cylinder 41 and the inner wall of the raw material storage cylinder 1, and the connecting strip needs to be able to break quickly when the needle-punching fitting 4 is pressed down.

[0047] The needle-punching member 3 can adopt any structure that can press down the needle-punching fitting 4 when pressed down. The present embodiment provides the following three needle-punching structures, but the needle-punching member 3 of the present utility model is not limited to the following three structures;

[0048] The first needle-punching structure of the needle-punching member 3: The needle-punching member 3 is a needle column with a pointed head at the bottom, which is directly fixed at the center of the inner cover pressing the top cover 2 (as shown in the appendix Figure 1 and 2 ). When pressing down the pressing top cover 2, the needle-punching member 3 first pierces the upper sealing film 14, and transmits the downward pressure to the top cover 42, driving the needle-punching fitting 4 to move downward to pierce the lower sealing film 19. In this way, a groove 43 facing the needle-punching member 3 can be arranged on the upper end surface of the top cover 42, and the needle-punching member 3 presses down facing the groove 43 to prevent the needle-punching member 3 from sliding and shifting along the top cover 42 when pressed down.

[0049] The second needle-punching structure of the needle-punching member 3: The needle-punching member 3 is in a cylindrical shape, and can be fixed on the inner cover pressing the top cover 2, or can be directly placed between the pressing top cover 2 and the upper cylinder body 11. When pressing down the pressing top cover 2, the needle-punching member 3 first pierces the upper sealing film 14, and transmits the downward pressure to the top cover 42, driving the needle-punching fitting 4 to move downward to pierce the lower sealing film 19.

[0050] The third needle-punching structure of the needle-punching member 3: The needle-punching member 3 also includes an upper cylinder body and a lower cylinder body, and the structure is like that of the raw material storage cylinder 1, and the size is smaller than that of the raw material storage cylinder 1. After being pressed down, it can be sleeved inside the raw material storage cylinder 1. The needle-punching member 3 of this structure can be fixed on the inner cover pressing the top cover 2, or can be directly placed between the pressing top cover 2 and the upper cylinder body 11. When pressing down the pressing top cover 2, the needle-punching member 3 first pierces the upper sealing film 14, and transmits the downward pressure to the top cover 42, driving the needle-punching fitting 4 to move downward to pierce the lower sealing film 19.

[0051] As a preferred solution, a through groove 44 is opened on the cylinder 41. The through groove 44 is opened upward along the cylinder wall of the cylinder 41, and can penetrate the entire cylinder 41, or can be only partially opened, and the length can be either long or short. By opening the through groove 44, as long as the cylinder 41 can pierce the lower sealing film 19 and slightly penetrate out, all the raw materials in the raw material storage cylinder 1 can enter the beverage bottle through the through groove 44. If the through groove 44 is not opened, even if the cylinder 41 can pierce the lower sealing film 19, it is very difficult for the raw materials in the cavity between the cylinder 41 and the inner cylinder 1 to enter the beverage bottle, or the flow rate is low.

[0052] As a preferred solution, a sharp cone 45 (a spoke in the attached drawing) surrounded by spokes or conical plates is provided at the lower end of the cylinder 41. By providing the sharp cone 45, it is easier to pierce the upper sealing film 14 and the lower sealing film 19. As a further optimized solution, a reinforcing rod 46 is provided between the center of the lower end face of the top cover 42 and the sharp cone 45 to increase the film-piercing strength of the sharp cone 45. When a through groove 44 is provided on the cylinder 41, about 1 mm at the lowermost end of the cylinder 41 may not be grooved (as shown in the attached Figure 9 drawing), to ensure that the sharp cone 45 does not deform when piercing the film.

[0053] As another solution, no sharp cone 45 is provided below the cylinder 41. Instead, a taper thorn 47 is provided at the lower end of the cylinder 41 to pierce the upper sealing film 14 and the lower sealing film 19. However, compared with the sharp cone 45, this method requires a greater impact speed and impact force for piercing the film. As a further improvement of this solution, a reinforcing rod 46 is provided inside the cylinder 41. The upper end of the reinforcing rod 46 is fixed on the top cover 42, the lower end is suspended, and is slightly shorter than the taper thorn 47. Since the aluminum film with good sealing effect is thicker and has greater elasticity, it is easy to rebound and block the pierced opening after being pierced. By providing the reinforcing rod 46, the rebound amount of the aluminum film can be reduced, and the pierced opening can be prevented from being blocked by the rebounding aluminum film, thus accelerating the outflow speed of the raw material.

[0054] In the structure of the present utility model, when pressing, the downward pressure of pressing the top cover 2 is transmitted to the acupuncture needle 3, and the acupuncture needle 3 transmits the downward pressure to the acupuncture needle fitting 4, which has a strong piercing force. A thick sealing film with better sealing performance can be used to produce a better sealing effect, and not only solid raw materials but also liquid raw materials can be stored.

[0055] A bottle cap ring 5 is provided on the raw material storage cylinder 1. The bottle cap ring 5 is integrally connected with the connecting ring plate 13 to form a sealable bottle cap. A theft-proof ring 51 is provided below the bottle cap ring 5. When in use, the lower cylinder body 12 is inserted into a bottle body (such as a mineral water bottle), and the bottle cap ring 5 is capped with the mineral water bottle cap. The inner diameter size, height size, etc., and the tightening thread of the bottle cap ring 5 of the present utility model can be adjusted according to the structure of the bottle body to meet the capping requirements of any bottle body.

[0056] As a preferred solution, the lower cylinder body 12 is covered with a protective cover 6. The inner diameter of the protective cover 6 matches the outer diameter of the bottle cap ring 5. A protective ring 61 is provided inside the protective cover 6, and the inner diameter of the protective ring 61 matches the outer diameter of the lower cylinder body 12. When the protective cover 6 is covered with the lower cylinder body 12, the protective cover 6 is sleeved outside the bottle cap ring 5, and the protective ring 61 is sleeved outside the lower cylinder body 12. The structure of the present utility model can store raw materials as an independent part. When in use, the protective cover 6 is removed, and the bottle cap ring 5 is capped on the bottle body (such as a mineral water bottle) for use. The present utility model can also be directly installed on the bottle body, and in this case, the protective cover 6 is not needed. Embodiment 2

[0057] The difference between this embodiment and Embodiment 1 lies in the different connection method of the pressing top cover 2 and the upper cylinder body 11, and the rest are the same as those in Embodiment 1. This embodiment mainly describes this difference.

[0058] In this embodiment, no pressing track groove 15 is provided on the upper cylinder body 11, and no pressing limit block 21 is provided inside the pressing top cover 2. The two are threadedly connected. Specifically:

[0059] External threads are provided on the upper cylinder body 11. Correspondingly, internal threads are provided on the pressing top cover 2. The pressing top cover 2 and the upper cylinder body 11 are threadedly connected. By rotating the pressing top cover 2 along the threads, the pressing top cover 2 drives the acupuncture needle 3 to press down, and the acupuncture needle 3 transmits the downward pressure to the acupuncture needle fitting 4.

[0060] Note: In view of the fact that the threaded connection is a conventional connection method, the threaded structure of the pressing top cover 2 and the upper cylinder body 11 is not shown in the drawings of the present utility model.

[0061] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit. Although the present utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in terms of form and details without departing from the scope defined by the claims of the present utility model.
