Description

Technical Field

[0001] This utility model relates to the field of food packaging container technology, specifically a swing-open dual-chamber self-mixing container with a one-way linkage sealing structure. Background Technology

[0002] In the field of food packaging container technology, especially in the field of portable beverages and instant mixed foods, how to achieve long-term isolated storage and convenient and efficient mixing of concentrates and solvents has always been a core problem that the industry urgently needs to solve. The current mainstream dual-chamber mixing container solutions on the market have many technical defects and cannot meet users' comprehensive needs for ease of operation, sealing reliability and mixing accuracy.

[0003] However, in actual use, the double-cap design requires 2-3 steps to complete the mixing process, which is not only cumbersome and affects the user experience, but also results in as many as 3.2 leakage points due to the multi-cap structure. This can easily lead to liquid leakage during transportation or storage, causing product waste and posing safety hazards. The puncture-type design relies on puncturing the sealing film to achieve mixing. It is a single-use design that cannot be reused, and the residue produced after puncturing the sealing film can easily contaminate the contents, posing a health risk to users. The squeeze capsule design uses individual capsules to carry the concentrate. The capsules are easily damaged by external pressure before transportation or use, resulting in premature mixing. At the same time, the release volume after the capsule ruptures is difficult to control, resulting in poor mixing accuracy, low success rate, and serious material waste. Finally, the independent liquid storage tank design requires the disassembly of a separate liquid storage tank component to complete the drinking process, which significantly interrupts the operation process, disrupts the user experience, and is prone to liquid spillage during disassembly.

[0004] Based on this, it is necessary to propose a swing-open dual-chamber self-mixing container with a one-way linkage sealing structure. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a swing-type dual-chamber self-mixing container with a one-way linkage sealing structure, which has strong practical adaptability and sealing performance, and can also release concentrates in a directional manner, thus solving the problems mentioned in the background technology.

[0006] This utility model provides the following technical solution: a swing-opening dual-chamber self-mixing container with a one-way linkage sealing structure, comprising a bottle body, a bottle cap, and a bottle stopper:

[0007] The bottle body is provided with a bottle mouth at the top, the bottle mouth has a recessed step, the recessed step is provided with at least one set of recesses in the circumference, and the bottle body forms a mixing chamber for containing solvent.

[0008] The stopper is disposed inside the bottle mouth, and its outer wall is provided with at least one set of protrusions that engage with the concave platform, and the bottom is provided with a sealing structure;

[0009] The bottle cap is fitted over the outside of the bottle opening, and its bottom extends to form a liquid storage cavity for containing the concentrate. The bottom is provided with a fastening structure that is compatible with the sealing structure at the bottom of the bottle stopper.

[0010] The engagement of the protrusion and the concave platform, the axial fixation of the stopper relative to the bottle mouth, and the disengagement of the cap's fastening structure from the stopper's sealing structure enable the release of the concentrate from the storage chamber into the mixing chamber.

[0011] Preferably, the bottle opening is provided with an external connector, and the inner wall of the bottle cap is provided with an internal connector that is adapted to the external connector.

[0012] Preferably, an auxiliary positioning structure is provided between the bottle cap and the bottle stopper. The auxiliary positioning structure includes a mating block disposed on the bottle cap and a mating groove disposed on the bottle stopper, wherein the mating block and the mating groove engage in a mating fit.

[0013] Preferably, the stopper is provided with a release groove for releasing the concentrate.

[0014] Preferably, the sealing structure of the bottle stopper is a T-shaped sealing skirt.

[0015] Preferably, the bottle cap has a ring-shaped snap-fit ​​structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This type of swing-open dual-chamber self-mixing container with a one-way linkage sealing structure achieves axial fixation of the stopper relative to the bottle mouth through the engagement transmission structure of the concave platform of the bottle body and the protrusion of the stopper. Combined with the precise linkage between the cap fastening structure and the stopper sealing structure, the seal can be stably released when needed, allowing the concentrate in the storage chamber to be directionally released into the mixing chamber. This ensures complete isolation between the concentrate and the solvent when not in use, preventing premature mixing and deterioration, while also enabling efficient release during use to meet immediate mixing requirements.

[0018] 2. This type of swing-open dual-chamber self-mixing container with a one-way linkage sealing structure has a sealing structure at the bottom of the stopper and a matching snap-fit ​​structure at the bottom of the cap. When the two are tightly snapped together, they can form a strong seal, effectively preventing leakage of concentrate in the storage chamber and evaporation of solvent in the mixing chamber. At the same time, the structural fit between the stopper and the bottle mouth further enhances the overall sealing performance, ensuring the stability of the container during transportation and storage and improving product safety.

[0019] 3. This type of swing-open dual-chamber self-mixing container with a one-way linkage sealing structure provides a stable foundation for the connection between the cap and the bottle body through the matching of the external connector on the outside of the bottle mouth and the internal connector on the inner wall of the cap, preventing loosening during use; the engaging engagement of the locking block and the locking groove in the auxiliary positioning structure further improves the positioning accuracy between the cap and the stopper, ensuring stable and reliable transmission and reducing operational errors.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Please see Figure 1-5 A swing-open dual-chamber self-mixing container with a one-way linkage sealing structure includes a bottle body 1, a bottle cap 2, and a bottle stopper 3.

[0032] The bottle body 1 has a bottle mouth 110 at the top, the bottle mouth 110 has a recessed step, the recessed step has at least one set of recesses 112 around its circumference, and the bottle body 1 forms a mixing chamber for containing solvent.

[0033] The bottle mouth 110 has a 15-25mm thickened recessed step, preferably 20mm. The recessed step has 6 asymmetrical trapezoidal recesses 112 around its circumference. The advance angle α of the recesses 112 satisfies 25°≤α≤35°, preferably 30°, and the retreat angle β satisfies 85°≤β≤95°, preferably 90°, forming a mechanical ratchet mechanism. The volume of the liquid storage chamber is 5%-15% of the mixing chamber, and the inner wall is covered with a moisture-proof layer.

[0034] The bottle stopper 3 is located inside the bottle mouth 110, and its outer wall is provided with at least one set of protrusions 310 that engage with the recess 112, and the bottom is provided with a sealing structure.

[0035] The bottle stopper 3 is made of food-grade silicone through injection molding and is located inside the bottle mouth 110. Its outer wall has 6 protrusions 310 with a hardness of Shore A50±5 and a height of 1.2mm that engage with the recess 112.

[0036] The bottle cap 2 is fitted outside the bottle mouth 110, and its bottom extends to form a liquid storage cavity for containing the concentrate. The bottom is provided with a fastening structure that matches the bottom sealing structure of the bottle stopper 3.

[0037] The bottle cap 2 is made of PP injection molding and is fitted outside the bottle mouth 110. Its bottom extends to form a liquid storage cavity with a volume of 5%-15% of the mixing cavity. The bottom is provided with a ring buckle 220 with a chamfer of 15° as a fastening structure that matches the sealing skirt.

[0038] The engagement of the protrusion 310 and the concave platform 112 drives the bottle stopper 3 to be axially fixed relative to the bottle mouth 110. The fastening structure of the bottle cap 2 and the sealing structure of the bottle stopper 3 are released, thereby realizing the release of the concentrate in the storage chamber to the mixing chamber.

[0039] When the bottle cap 2 is rotated, the protrusion 310, along the trajectory of the concave platform 112, transforms the rotational motion into axial displacement of the bottle cap 2 through the meshing angle difference design of 30° advance angle and 90° retreat angle, thereby achieving axial fixation of the bottle stopper 3 relative to the bottle mouth 110. At the same time, the fastening structure of the bottle cap 2 and the sealing structure of the bottle stopper 3 are released, and the concentrate in the liquid storage chamber is directionally released into the mixing chamber through the release groove 320.

[0040] like Figure 2 and Figure 5 As shown, in this embodiment, the bottle opening 110 is provided with an external connector 111, and the inner wall of the bottle cap 2 is provided with an internal connector 210 that is adapted to the external connector 111.

[0041] This structure provides a solid foundation for the connection between the bottle cap and the bottle body. In conjunction with the ratchet mechanism of the recessed platform 112 and the protrusion 310, it prevents slippage or loosening during rotation and ensures transmission efficiency.

[0042] like Figure 5 As shown, in this embodiment, an auxiliary positioning structure is provided between the bottle cap 2 and the bottle stopper 3. The auxiliary positioning structure includes a mating block 230 provided on the bottle cap 2 and a mating groove 340 provided on the bottle stopper 3. The mating block 230 and the mating groove 340 engage and cooperate.

[0043] This structure further improves the positioning accuracy of the bottle cap and stopper, ensuring precise linkage between the annular buckle 220 and the T-shaped sealing skirt 330 during rotation, and reducing operational errors in releasing the seal.

[0044] like Figure 4 As shown, the bottle stopper 3 in this embodiment is provided with a release groove 320 for releasing the concentrate.

[0045] like Figure 4 and Figure 5 As shown, the sealing structure of the bottle stopper 3 in this embodiment is a T-shaped sealing skirt 330, which is provided with radial reinforcing ribs and the thickness of the reinforcing ribs is 1.2-2.0mm.

[0046] The T-shaped sealing skirt 330 adopts an elastic deformation design, forming a static seal with the bottle cap 2 ring buckle 220 to form the first sealing surface. When not in use, it can completely prevent the concentrate from contacting the solvent. For high-pressure scenarios such as carbonated beverages, the T-shaped sealing skirt 330 can increase the hardness by 15%, ensuring that the CO2 leakage rate is <5% / 24h.

[0047] like Figure 5 As shown, the fastening structure of the bottle cap 2 in this embodiment is a ring buckle 220;

[0048] The engagement depth of the ring buckle 220 and the T-shaped sealing skirt 330 has been optimized to ensure a sealing force of ≥30N when not rotated, and the torque required to release the seal when rotated is controlled within 0.5-1.0N・m, balancing sealing reliability and ease of operation.

[0049] Furthermore, when mixing honey and water: Bottle neck 110: HDPE injection molding, step recessed 20mm, recessed platform 112 with an inward angle of 30° / outward angle of 90°; bottle stopper 3: food-grade silicone, raised dot 310 with a height of 1.2mm, skirt wall thickness of 1.5mm; bottle cap 2: PP injection molding, liquid storage chamber volume of 40ml, buckle chamfer of 15°; during filling: 35ml of honey is injected into the liquid storage chamber, and 300ml of purified water is injected into the bottle body; when using, rotate the bottle cap counterclockwise 2 to 120°, and the honey will be released within 3 seconds, ready to drink directly;

[0050] Based on the above: when lemon soda water is mixed: EPDM sealing ring is added to stopper 3, the volume of the liquid storage chamber is reduced to 25ml, the bottle body is filled with carbonated water at a pressure of 0.35MPa, the CO2 leakage rate during the opening process is <3%, and the bubble retention rate after mixing is 92%;

[0051] Based on the above: When the powder and liquid are mixed: the oxygen permeability of the EVOH moisture-proof coating in the storage chamber is increased to <0.1cc / m 2 • Day, the bottle stopper has 3 protrusions and 310 added vibration teeth to promote powder falling, with 30g protein powder release residue <0.15g, and mixing uniformity >95%.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
