Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, and in particular to a freshness-locking cap device with water separation function. Background Technology

[0002] In the field of food packaging technology, the packaging design, preservation performance optimization, and user experience upgrade of liquid foods have long been the core directions of industry research and innovation. They are directly related to the market competitiveness of products, consumer acceptance, and the sustainable development of the food industry. With increasingly diversified consumer demands, consumers not only have higher requirements for the freshness and quality stability of liquid foods, but also expect to have a personalized experience during consumption.

[0003] Existing food packaging containers typically use liquids of fixed concentrations, which cannot meet consumers' personalized taste demands. Furthermore, most bottles use water-separation type freshness-locking caps, which makes drinking inconvenient. Traditional containers also cannot effectively separate water and concentrated ingredients, leading to easy degradation of flavor substances during storage. Although MCS technology can significantly improve the preservation effect through layered water control design, the existing structure is complex and costly. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: existing food packaging containers typically use liquids of fixed concentration, which cannot meet consumers' personalized taste needs, and most of the bottles are water-separation type fresh-locking caps, which makes drinking inconvenient. Traditional containers also cannot effectively separate water and concentrated ingredients, leading to easy degradation of flavor substances during storage. Although MCS technology can significantly improve the preservation effect through layered water control design, the existing structure is complex and costly. Therefore, this invention proposes a fresh-locking cap device with water separation function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A freshness-locking cap device with water separation function includes an outer shell and an inner liner. The outer shell is cylindrical and hollow inside. The inner liner is rotatably disposed inside the outer shell and its vertical movement is restricted by a limiting component. The inner liner is hollow inside and has a T-shaped partition fixedly installed on it. The partition divides the interior of the inner liner into two storage spaces for storing concentrated liquid. The bottom of the inner liner has symmetrical openings that are connected to the two storage spaces respectively. The bottom of the outer shell has a liquid outlet that is connected to its own interior. The top diameter of the liquid outlet is smaller than the thickness of the partition. The bottom of the partition covers the top opening of the liquid outlet. The liquid outlet is located on the movement path of the two openings.

[0006] Preferably, the limiting component includes a plurality of first rings fixedly installed longitudinally at equal intervals inside the outer shell and a plurality of second rings fixedly installed longitudinally at equal intervals on the outer wall of the inner liner, wherein the plurality of first rings and the plurality of second rings fit together.

[0007] Preferably, an installation ring is fixedly installed at the top of the outer shell, and a rubber ring is bonded to the inner wall of the installation ring, with the inner wall of the rubber ring in sealed sliding contact with the outer wall of the inner liner.

[0008] Preferably, a cover is fixedly installed on the outer wall at the top of the outer casing, and the inner wall of the cover is provided with a spiral pattern, which is used to achieve sealing and opening of the device.

[0009] Preferably, the bottom of the cover is provided with an anti-theft ring, and the top of the anti-theft ring and the bottom of the cover are fixedly connected by a ring of evenly distributed easily broken connecting ribs.

[0010] Preferably, the longitudinal section of the liquid outlet is frustum-shaped, and the top opening diameter of the liquid outlet is smaller than the bottom opening diameter.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The internal space is divided into two independent concentrated liquid storage areas by the T-shaped partition inside the inner liner. With the staggered design of the bottom opening and the liquid outlet on the outer shell, the concentrated liquid can be completely isolated from external moisture when not in use. This effectively prevents the degradation of flavor substances due to long-term mixing, significantly extends the shelf life of the product, and ensures the original flavor and quality of the liquid food. 2. By utilizing the rotational characteristics of the inner tank, the inlets and outlets of different storage spaces can be selectively connected, allowing for flexible control of the outflow and mixing ratio of different concentrates. This satisfies consumers' personalized needs for flavor concentration and enhances the diversity and flexibility of the user experience. 3. The first and second rings fit together to form a limiting component, which can reliably limit the vertical movement of the inner liner without affecting its rotation function. Combined with the sealing sliding contact between the rubber ring on the inner side of the mounting ring and the outer wall of the inner liner, it effectively prevents liquid leakage and ensures the structural stability and sealing of the device during carrying and use. 4. The spiral pattern design of the cap allows it to quickly seal or open with the container body, making operation simple and effortless. The frustum-shaped liquid outlet structure facilitates smooth liquid flow, avoiding residue and waste. 5. The anti-theft ring at the bottom of the cover is connected to the cover by a easily broken connecting rib. When the cover is opened for the first time, the connecting rib breaks, which can be used to visually determine whether the product has been opened, thus improving the product's security and reliability. 6. The separate design of the outer shell and inner liner reduces production difficulty and reduces the volume of the bottle occupied by the cap. The compact design of each component is easy to process and assemble, eliminating the need for complex and precise manufacturing processes. This effectively controls production costs and makes it suitable for large-scale industrial production and widespread application. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0016] Reference Figures 1-4 A freshness-locking cap device with water separation function includes an outer shell 1 and an inner liner 2. The outer shell 1 is cylindrical and hollow inside. The inner liner 2 is rotatably disposed inside the outer shell 1, and its vertical movement is restricted by limiting components, such as... Figure 6 As shown, the inner liner 2 is hollow inside and has a T-shaped partition 3 fixedly installed inside. The partition 3 divides the inside of the inner liner 2 into two storage spaces for storing concentrated liquid.

[0017] Reference Figure 5 and Figure 7 The inner liner 2 has symmetrical openings 4 at its bottom, each connecting to one of the two storage spaces. The outer shell 1 has a liquid outlet 5 at its bottom, connecting to its own interior. The top diameter of the liquid outlet 5 is smaller than the thickness of the partition 3. The bottom of the partition 3 covers the top opening of the liquid outlet 5. The liquid outlet 5 is located on the moving path of the two openings 4, such as... Figure 8 As shown, the longitudinal section of the liquid outlet 5 is frustum-shaped, and the top opening diameter of the liquid outlet 5 is smaller than the bottom opening diameter.

[0018] In the initial state, i.e. when not in use, the inner liner 2 is stably installed inside the outer shell 1 by the limiting component. At this time, the bottom of the T-shaped partition 3 completely covers the top opening of the liquid outlet 5 at the bottom of the outer shell 1. The two ports 4 are located on both sides of the liquid outlet 5 and are not connected to the liquid outlet 5. Since the ports 4 and the liquid outlet 5 are misaligned, the concentrated liquid in the two storage spaces divided by the T-shaped partition 3 inside the inner liner 2 cannot flow out of the storage space, thus achieving complete isolation between the concentrated liquid and the external environment.

[0019] When it is necessary to use the device to release one of the concentrated liquids, the inner liner 2 can be rotated so that the inner liner 2 rotates relative to the outer shell 1 around its own axis. During the rotation, the limiting component ensures that the inner liner 2 only rotates horizontally and does not produce vertical displacement. When rotated to a preset angle, one of the ports 4 is aligned and connected with the liquid outlet 5. The concentrated liquid in the storage space corresponding to the port 4 will flow out through the port 4 and the liquid outlet 5 in sequence. Since the longitudinal section of the liquid outlet 5 is frustum-shaped and the diameter of the top opening is smaller than the diameter of the bottom opening, it can form a guiding effect, so that the concentrated liquid flows out smoothly and reduces residue.

[0020] If you find the taste too bland after releasing one concentrated liquid, you can rotate the inner liner 2 to align the other opening 4 with the liquid outlet 5, thus releasing another portion of concentrated liquid.

[0021] When liquid release is no longer required, rotate the inner liner 2 back to the initial position so that both openings 4 are misaligned with the liquid outlet 5. The bottom of the partition 3 completely covers the top opening of the liquid outlet 5 again, restoring the seal and preventing the concentrated liquid from accidentally leaking out.

[0022] The above-mentioned rotation control method can flexibly realize the individual release or proportional mixing and release of the two concentrated liquids to meet different usage needs.

[0023] Reference Figure 4The limiting components include multiple first rings 6 that are longitudinally and equidistantly fixed inside the outer shell 1 and multiple second rings 7 that are longitudinally and equidistantly fixed on the outer wall of the inner liner 2, with the multiple first rings 6 and multiple second rings 7 fitting together.

[0024] During assembly, multiple first rings 6 and multiple second rings 7 interlock and fit together to form an axial limiting structure. This structure can effectively limit the vertical movement of the inner liner 2 within the outer shell 1, preventing it from moving up and down, while not affecting the smooth rotation of the inner liner 2 around its own axis. This ensures that the device is structurally stable and flexible in operation during use. At the same time, the first rings 6 and the second rings 7 can prevent the concentrated liquid from leaking.

[0025] Reference Figure 8 An installation ring 8 is fixedly installed at the top of the outer shell 1. A rubber ring is bonded to the inner wall of the installation ring 8, and the inner wall of the rubber ring is in sealing sliding contact with the outer wall of the inner liner 2.

[0026] The inner wall of the rubber ring fits tightly against the outer wall of the inner liner 2, forming a sealed sliding contact structure. This not only ensures the smoothness of the inner liner 2 during rotation and adjustment, but also effectively prevents liquid from leaking from the gap between the outer shell 1 and the top of the inner liner 2, further improving the overall sealing performance of the device.

[0027] Reference Figure 8 A cover 9 is fixedly installed on the outer wall at the top of the outer casing 1. The inner wall of the cover 9 is provided with a spiral pattern 10. The spiral pattern 10 is adapted to the thread of the bottle mouth of the container (not shown). The spiral pattern 10 is used to achieve the sealing and opening of the device.

[0028] By engaging the spiral pattern 10 with the threaded opening of the container, the device can be easily connected to the container for sealing or opening by rotating the cap 9, ensuring the overall airtightness of the packaging while improving ease of use.

[0029] Reference Figure 4 and Figure 8 The bottom of the cover 9 is provided with an anti-theft ring 11, and the top of the anti-theft ring 11 and the bottom of the cover 9 are fixedly connected by a ring of evenly distributed easily broken connecting ribs.

[0030] When unopened, the easily broken connecting ribs remain intact, ensuring the sealing and safety of the device. When the cover is opened for the first time, the easily broken connecting ribs break under force, which can be used to visually determine whether the product has been opened, thus playing a role in preventing theft and counterfeiting.

[0031] In this invention, the internal space is divided into two independent concentrated liquid storage areas by the T-shaped partition 3 inside the inner liner 2. With the staggered design of the bottom opening 4 of the inner liner 2 and the bottom outlet 5 of the outer shell 1, the concentrated liquid can be completely isolated from external moisture when not in use. This effectively prevents the degradation of flavor substances due to long-term mixing, significantly extends the shelf life of the product, and ensures the original flavor and quality of the liquid food. At the same time, by utilizing the rotation characteristics of the inner liner 2, the openings 4 corresponding to different storage spaces of the inner liner 2 can be selectively connected to the outlet 5 of the outer shell 1. This allows for flexible control of the outflow and mixing ratio of different concentrated liquids, meeting consumers' personalized needs for flavor concentration and enhancing the diversity and flexibility of the user experience.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
