Description

Technical Field

[0001] This utility model belongs to the field of bottle cap technology, specifically, it relates to a beverage storage cap. Background Technology

[0002] Bottled beverages are popular due to their superior taste, and most are currently produced directly from the bottle. Compared to purified or mineral water, beverages have higher requirements for shelf life, necessitating additives to extend their shelf life. Additionally, some beverage bottle caps are designed to store concentrated ingredients (hereinafter referred to as ingredients), sealed with a composite aluminum foil, and then heat-sterilized. Before consumption, the ingredients in the cap are mixed with the water in the bottle, improving the taste and reducing the requirements for ingredient preservation. Currently, the technology of storing ingredients by incorporating storage space in beverage bottle caps has been researched and applied.

[0003] Designing beverage bottle caps to store ingredients, which are then mixed with water in the bottle before drinking, can improve the beverage's taste. This technology of storing ingredients by incorporating storage space within beverage bottle caps has already been researched and applied.

[0004] The sealing of raw materials in beverage bottle caps typically involves creating a storage cavity within the cap, sealing the cavity with an aluminum foil, and using a composite aluminum foil to meet the requirements for heat sterilization after sealing. Before consumption, the raw material is mixed with water by puncturing the aluminum foil. Storing raw materials in beverage bottle caps requires not only a good seal to prevent moisture or spoilage, but also ensuring the bottle is sealed with water and that the raw material can easily enter the bottle and mix with the water before consumption. Because of the good elasticity of the aluminum foil, a certain puncture force is required to puncture it. Furthermore, due to its elasticity, the aluminum foil easily deforms and moves away from the puncture needle during puncture, thus requiring a sufficient needle length and pressing stroke. The thicker the aluminum foil, the greater the puncture force required, and the greater the elastic deformation upon puncture. To ensure the aluminum foil can be easily punctured, current beverage bottle caps mostly achieve this by reducing the thickness of the aluminum foil or weakening the seal between the aluminum foil and the storage cavity. However, this method leads to poor sealing, increasing the risk of moisture absorption and spoilage after prolonged storage. If the stored material is liquid, leakage is highly likely. Therefore, current beverage bottle caps are mostly only suitable for storing solid materials and cannot meet the storage requirements for liquid beverage ingredients. Patent CN220555458U provides a beverage bottle cap that can store liquid ingredients, effectively solving the aforementioned problems. However, providing a beverage storage cap with a novel structure that can accommodate liquid ingredient storage, has good sealing properties, and allows for easy puncture of the aluminum foil still has significant implications.

Detailed Implementation

[0040] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0041] In the description of this utility model, unless otherwise stated, the terms "upper" and "lower" and the directional or morphological relationships indicated are based on the directional or morphological relationships shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0042] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances. Example 1

[0043] like Figures 1 to 12 As shown, the beverage storage cover includes a raw material storage cylinder, a top cover 1, a puncture cylinder, and a bottle cap ring 6.

[0044] The piercing cylinder is a stepped reducing cylinder, comprising an upper cylinder A8, a lower cylinder A9, and a connecting ring plate A10 connecting the upper cylinder A8 and the lower cylinder A9. The diameter of the upper cylinder A8 is larger than that of the lower cylinder A9. The inner cavities of the upper cylinder A8 and the lower cylinder A9 are connected. A piercing element 3 is provided in the lower port of the lower cylinder A9. The piercing element 3 is a conical, pyramidal, or cross-shaped structure that can pierce the sealing film at the lower port of the lower cylinder B12 when the lower cylinder B12 moves downward.

[0045] The outer wall of the upper cylinder A8 is provided with a track groove 4, which is formed by a protrusion on the outer wall of the upper cylinder A8. The track groove 4 includes a vertical track and an upper horizontal track and a lower horizontal track connected to the vertical track, and two track grooves 4 are symmetrically arranged. Correspondingly, the inner wall of the upper cover 1 is provided with two limiting blocks 5 that match the width and depth of the track groove 4. After the upper cover 1 is fitted over the upper cylinder A8, the limiting blocks 5 can move along the track groove 4.

[0046] The bottle cap ring 6 is integrally connected with the connecting ring plate A10, forming a sealed bottle cap structure. When this utility model is closed on the bottle body (e.g., a mineral water bottle), the lower cylinder A9 is inserted into the mouth of the mineral water bottle, and the bottle cap ring 6 and the connecting ring plate A10 seal the mouth of the mineral water bottle. The lower end of the bottle cap ring 6 is provided with an anti-theft ring 17.

[0047] The raw material storage cylinder is also a stepped-diameter cylinder, including an upper cylinder B11, a lower cylinder B12, and a connecting ring plate B13 connecting the upper cylinder B11 and the lower cylinder B12. The diameter of the upper cylinder B11 is larger than that of the lower cylinder B12, and their inner cavities are connected, forming a raw material storage cavity. The upper port of the upper cylinder B11 is sealed by an upper sealing element 2, which is a food-grade sealing film. The lower port of the lower cylinder B12 is sealed by a lower sealing element 23, which is also a food-grade sealing film. The raw material is stored in the raw material storage cylinder, and when the lower sealing element 23 is punctured, the raw material flows out of the raw material storage cylinder.

[0048] The outer diameter of the lower cylinder B12 is smaller than the inner diameter of the lower cylinder A9, and the outer diameter of the upper cylinder B11 is smaller than the inner diameter of the upper cylinder A8. The lower cylinder B12 can be nested inside the lower cylinder A9, and the upper cylinder B11 can be nested inside the upper cylinder A8. The raw material storage cylinder is nested inside the puncture cylinder in this way. As an optional solution, both the raw material storage cylinder and the puncture cylinder are made of plastic, and the two are fitted together by the elasticity of the plastic. As another optional solution, a sealing ring 19 can be provided on the outer wall of the lower cylinder B12. When the raw material storage cylinder is pressed down, the lower seal 23 (food-grade sealing film) is punctured by the puncture part 3, and the sealing ring 19 can block the gap between the lower cylinder B12 and the lower cylinder A9 to prevent beverage leakage.

[0049] The upper cover 1 covers the nested raw material storage cylinder and puncture cylinder, and the length of the upper cover 1 can cover the raw material storage cylinder and puncture cylinder.

[0050] Rotating the top cover 1 causes the limiting block 5 to be in the vertical section of the track groove 4. Pressing down on the top cover 1 pushes the raw material storage cylinder downwards, and the piercing element 3 punctures the lower seal 23 (food-grade sealing film) on the lower cylinder B11, allowing the raw material stored in the storage cylinder to flow out. Due to the vertical track section, this invention provides a pressing stroke by quickly pressing down on the top cover 1. This stroke generates an impact force when the top cover 1 is pressed down quickly, which can puncture even sealing films with high toughness and strength.

[0051] As a preferred embodiment, the lower cylinder A9 is longer than the lower cylinder B12. Both the upper seal 2 and the lower seal 23 of this invention are sealing films, made of food-grade plastic composite film with high toughness and strength. Before the upper cover 1 is pressed down, the contact between the lower seal 23 and the puncture element 3 will not cause the lower seal 23 to be punctured. When the upper cover 1 is pressed down, under the limitation of the limiting block 5 and the pressure track groove 4, the upper cover 1 presses down vertically along the vertical section of the pressure track groove 4. The vertical section provides the upper cover 1 with a downward pressing stroke, which increases the impact force during pressing, allowing the puncture element 3 to puncture the sealing film. The structure of the lower cylinder A9 being longer than the lower cylinder B12 ensures that the lower seal 23 contacts the puncture element 3, ensuring sufficient puncture stroke and puncture. Therefore, the structure of this invention can use a sealing film with high toughness and strength to seal the raw material storage cylinder, providing good sealing performance. It can store not only fixed raw materials but also liquid raw materials, such as concentrated fruit juice, concentrated coffee, and liquid honey. Furthermore, due to the high toughness of the sealing film, it can also meet the requirements for sealed storage of liquid beverages and heat sterilization after sealing.

[0052] As a preferred embodiment, the lower end of the lower cylinder B12 is provided with a reduced diameter section 14. The lower sealing element 23 (food-grade plastic composite film, hereinafter referred to as the sealing film) is sealed on the lower end face of the reduced diameter section 14. During processing, in order to ensure the sealing effect, the sealing film will exceed the outer diameter of the reduced diameter section 14. The structure of the reduced outer diameter of the reduced diameter section 14 can prevent the sealing film exceeding the outer diameter of the reduced diameter section 14 from blocking between the lower cylinder B12 and the lower cylinder A9 when pressing down, which would lead to increased pressing resistance or inability to press down. The puncture element 3 is preferably a conical needle structure. For example, the conical needle can be formed by the cross connection of the centerlines of two or more conical plates (see attached). Figure 8 It can be formed by connecting the apexes of two cones (or by connecting the apexes of two or more prisms). Figure 9 (It consists of three prisms). After the lower seal 23 (food-grade sealing film) is punctured, the raw material flows out.

[0053] The piercing element 3 with its conical structure has better strength and is easier to pierce the sealing membrane. The track groove 4 design includes a lower horizontal track structure. After the upper cover 1 is pressed down, the upper cover 1 can be rotated along the lower horizontal track, which will drive the piercing cylinder to rotate. During the rotation, there is a rotational movement between the lower sealing element 23 and the piercing element 3, which can increase the gap between the pierced sealing membrane and the piercing element 3, making the material discharge smoother.

[0054] As a preferred embodiment, two locking blocks 7 are provided in the vertical section of the track groove 4. The locking blocks 7 are inclined blocks with a slope whose thickness increases from top to bottom. The structure of the locking blocks 7 allows the limiting block 5 to slide down smoothly, and once pressed, it is limited by the locking blocks 7 to prevent it from sliding up.

[0055] As a preferred option, a limiting block channel 18 is provided at the upper end of the track groove 4. The limiting block channel 18 is connected to the horizontal section of the track groove 4. The limiting block channel 18 allows the limiting block 5 to smoothly enter the track groove 4, so that the upper cover 1 can smoothly be limited and closed with the upper cylinder A9.

[0056] As a preferred embodiment, a protective cap 15 is fitted onto the lower end of the lower cylinder A9, with the inner diameter of the protective cap 15 fitting against the outer diameter of the bottle cap ring 6. A protective ring 16 is provided inside the protective cap 15, with its inner diameter fitting against the outer diameter of the lower cylinder A9. When the protective ring 15 is closed to the lower cylinder A9, it covers the outside of the bottle cap ring 6, while the protective ring 16 covers the outside of the lower cylinder A9. This invention allows for independent storage of raw materials. When in use, the protective ring 15 is removed, and the bottle cap ring 6 is placed on the bottle (e.g., a mineral water bottle). Alternatively, this invention can be directly installed on a mineral water bottle, and the bottle cap ring 6 can be universally used for sealing the bottle. In this case, the protective cap 15 is not required, and an anti-theft ring 17 is provided on the bottle cap ring 6.

[0057] Furthermore, in the structure of this utility model, only the lower seal 23 is punctured during use, while the upper seal 2 remains intact. To ensure that the liquid can flow smoothly from the raw material storage cylinder, air needs to enter the raw material storage cylinder when it is punctured. Therefore, when this utility model is directly installed on the bottle body, the bottle cannot be filled with water. Alternatively, a through groove 20 can be opened on the side wall of the upper cylinder A.

[0058] The inner diameter, height, and tightening thread of the bottle cap ring 6 of this invention can be adjusted according to the structure of the bottle to meet the capping requirements of any bottle. Example 2

[0059] Compared with Example 1, the stepped structure of the raw material storage cylinder 2 remains unchanged, as do the stepped structure of the puncture cylinder and its connection structure with the bottle cap ring 6. The nesting / sleeving relationship between the puncture cylinder, the raw material storage cylinder, and the upper cover 1 remains unchanged. This example mainly changes the structure of the upper sealing element 2 and the lower sealing element 23, and also changes the puncture method of the lower sealing element 23.

[0060] As attached Figure 8-11 As shown in 13-20:

[0061] In this embodiment, the puncture cylinder has two symmetrical through slots 20 on the side wall of the upper cylinder A8. The main function of the through slots 20 is to provide an air inlet channel after the lower seal 23 is punctured or separated from the lower cylinder 12, ensuring smooth material discharge from the raw material storage cylinder. Simultaneously, two limiting protrusions 21 are provided on the inner wall of the upper cylinder A8, and the limiting protrusions 21 can be positioned directly above the through slots 20.

[0062] In this embodiment, the outer wall of the upper cylinder B11 is provided with a spiral groove 22. The spiral groove 22 is formed by a protrusion on the outer wall of the upper cylinder B11. The width and depth of the spiral groove 22 match the limiting protrusion 21.

[0063] In this embodiment, the upper sealing element 2 is a sealing cap, and the sealing cap and the upper cylinder B11 are preferably integrated structures, preferably integrated processing structures; as an optional solution, the sealing cap can also be designed as a bottle cap (structure is the same as mineral water bottle cap), and a threaded bottle mouth is opened at the upper port of the upper cylinder B11, so that the sealing cap and the bottle mouth of the upper cylinder B11 can be sealed together.

[0064] In this embodiment, the lower sealing element 23 can be selected from two structures: the first is a pull-ring bottle cap; the second is a food-grade sealing film.

[0065] In this embodiment, the puncturing element 3 can be selected from two structures: the first structure is a hook (as shown in the attached image). Figure 15 The second structure is the same as the cone-shaped structure in Example 1.

[0066] When the sealing element 23 is sealed at the lower port of the lower cylinder B using a pull-ring bottle cap, the puncture element 3 is selected as a hook structure; when the sealing element 23 is sealed at the lower port of the lower cylinder B using a sealing film, the puncture element 3 is selected as the conical puncture structure of copper embodiment 1.

[0067] In this embodiment: the inner wall of the upper cover 1 is provided with a locking block 24; the outer side of the upper sealing member 2 (sealing cover structure) is provided with a locking groove 25, and the locking block 24 is locked in the locking groove 25. It should be noted that the main function of the locking block 24 and the locking groove 25 is to drive the upper cylinder B11 to rotate when the upper cover 1 rotates. Any structure that can achieve this function is acceptable, and is not limited to the locking block 24 and the locking groove 25.

[0068] This embodiment demonstrates the raw material release operation of the raw material storage cylinder:

[0069] (1) The lower sealing element 23 is a pull ring bottle cap, and the puncture element 3 is a hook structure:

[0070] After the overall structure of this utility model is assembled, the upper cylinder B11 is at the lowest position (the lowest point of the rotatable height along the spiral groove 22), and the locking block 24 is locked in the locking groove 25. When it is necessary to release the raw material in the raw material storage cylinder, the upper cover 1 is rotated. Since the locking block 24 is locked in the locking groove 25, the rotation of the upper cover 1 drives the upper cylinder B11 to rotate. Under the limitation of the limiting protrusion 21 and the spiral groove 22, the upper cylinder B11 rotates upward, and the hook catches the pull ring of the pull ring bottle cap, so that the pull ring bottle cap is separated from the lower cylinder B12, and the raw material is released from the raw material storage cylinder.

[0071] (2) The lower seal 23 is a sealing membrane, and the puncture part 3 is a cone-shaped structure:

[0072] After the overall structure of this utility model is assembled, the upper cylinder B11 is at the uppermost position (the uppermost point of the rotatable height along the spiral groove 22), and the locking block 24 is locked in the locking groove 25. When it is necessary to release the raw material in the raw material storage cylinder, the upper cover 1 is rotated. Since the locking block 24 is locked in the locking groove 25, the rotation of the upper cover 1 drives the upper cylinder B11 to rotate. Under the limitation of the limiting protrusion 21 and the spiral groove 22, the upper cylinder B11 rotates downward. The piercing part 3 of the cone-shaped structure pierces the sealing film, and the raw material is released from the raw material storage cylinder.

[0073] As an optional solution, the inner wall of the upper cover 1 does not have a locking block 24; the outer side of the upper sealing element 2 (sealing cover structure) does not have a locking groove 25. The main function of the upper cover 1 is to cover the piercing cylinder and the raw material storage cylinder. When it is necessary to release the raw material in the raw material storage cylinder, the upper cover 1 is removed, and the upper sealing element 2 (sealing cover structure) is held by hand and the upper cylinder B11 is rotated, which can also realize the upward or downward rotation of the upper cylinder B11.

[0074] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the 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 to it in form and detail without departing from the scope defined by the claims of this utility model.
