[0047] The present invention provides a packaging container.

[0048] Please refer to Figure 1 and Figure 3 , in an embodiment of the present invention, the packaging container includes:

[0049] A container body 100 having a receiving cavity with an open end; and

[0050] A lid structure, the lid structure includes a first lid group 200 and a second lid group 300. The first lid group 200 is provided at the open end of the container body 100 and has a communication port 201 provided in the receiving cavity. The second lid group 300 forms a sub-cavity with the first lid group 200. The second lid group 300 is slidably connected to the first lid group 200 so that the sub-cavity has a first state and a second state;

[0051] Wherein, in the first state, the communication port 201 is closed and the sub-chamber is sealed; in the second state, the communication port 201 is opened and the sub-chamber communicates with the accommodation chamber.

[0052] In the technical solution of the present invention, the packaging container includes a container body 100, the interior of the container body 100 is an accommodation chamber for holding a solution, a lid structure is provided at the open end of the container body 100, the lid structure includes a first lid group 200 and a second lid group 300, one end of the first lid group 200 is located in the accommodation chamber, and one end in the accommodation chamber has a communication port 201, the second lid group 300 extends into the accommodation chamber and is slidably connected to the first lid group 200. When the second lid group 300 slides to the first state, the second lid group 300 blocks the communication port 201 so that the sub-chamber formed by the first lid group 200 and the second lid group 300 is closed. A solution is placed in the sub-chamber, and the solution in the sub-chamber is different from the solution in the accommodation chamber. By sliding the second lid group 300, the second lid group 300 no longer blocks the communication port 201. At this time, the sub-chamber communicates with the accommodation chamber, and the solution in the sub-chamber flows into the accommodation chamber from the communication port 201 and mixes with the solution in the accommodation chamber. That is, through the setting of this packaging container, two different kinds of solutions can be accommodated, and the two solutions can be stored separately. When in use, by moving the second lid group 300, the solution in the sub-chamber enters the accommodation chamber and mixes with the solution in the accommodation chamber, so that the two solutions can be mixed without opening or contacting the internal solution, and then used after mixing. The whole process does not require opening the packaging container or contacting the solution, completely blocking the possibility of external pollutants such as dust and microorganisms in the air from entering, which is convenient for consumers to use, not only simple in operation but also improves the safety of the product. In addition, the sub-chamber is arranged in the accommodation chamber, and two different solutions are stored in the sub-chamber and the accommodation chamber, which also reduces the space occupied by the two solutions, and the space utilization is more reasonable.

[0053] Specifically, the container body 100 can be a cylindrical structure or a structure with a rectangular cross-section. The shape of the container body 100 is not limited. In this embodiment, the container body 100 is a cylindrical structure. The end of the container body 100 has a necking 110 with a diameter smaller than that of the container body 100. An opening is provided at the necking 110, and the lid structure is installed at the necking 110. Among them, the lid structure includes a fixed first lid group 200 and a slidably arranged second lid group 300 to open or close the sub-chamber.

[0054] Please refer to Figure 5 and Figure 9 , in the embodiment of the present invention, the first lid group 200 includes a connecting lid 210. The connecting lid 210 is provided at the opening of the container body 100 and is snap-connected to the container body 100. The second lid group 300 includes a central tube 310. One end of the central tube 310 extends into the accommodation chamber and abuts against the first lid group 200 in the first state to close the communication port 201.

[0055] The packaging container further includes a guiding component. The first lid group 200 and the second lid group 300 are connected by the guiding component, so that the second lid group 300 moves along the axial direction of the container body 100 to open or close the communication port 201.

[0056] Specifically, connecting the first lid group 200 and the second lid group 300 through the guiding component enables the second lid group 300 to slide axially relative to the first lid group 200 to move away from the first lid group 200, so that the partition chamber communicates with the accommodating chamber. Specifically, the first lid group 200 includes a connecting lid 210. The connecting lid 210 is arranged at the necking 110. One end extends into the accommodating chamber through an opening, and the other end is outside the accommodating chamber and is clamped with the necking 110. The second lid group 300 includes a central tube 310 extending into the accommodating chamber, and the part of the connecting lid 210 in the accommodating chamber is sleeved on the outer periphery of the central tube 310. The communication port 201 is arranged on the connecting lid 210. The connecting lid 210 and the central tube 310 enclose a partition chamber. Through the arrangement of the guiding component, the central tube 310 slides axially in the connecting lid 210, so that it moves away from or close to the communication port 201. Before initial use, the outer wall of the central tube 310 blocks the communication port 201, so that the partition chamber is closed. At this time, the solution in the partition chamber and the solution in the accommodating chamber are stored independently. When in use, pull the central tube 310 to make it move axially to move away from the communication port 201. At this time, the partition chamber communicates with the accommodating chamber, and the solution in the partition chamber flows into the accommodating chamber to form a mixed solution. The mixing of the solution can be realized without contacting the internal solution, avoiding external pollutants from entering the solution and affecting the quality and use safety of the product.

[0057] Please refer to Figure 5 、 Figure 6 and Figure 9 , in the embodiment of the present invention, the guiding component includes:

[0058] A guide rail groove 400 is arranged on the outer wall of the central tube 310, and the guide rail groove 400 is inclined.

[0059] A convex column 410 protrudes from the inner wall of the connecting lid 210, and the convex column 410 is slidably arranged in the guide rail groove 400 so that when the central tube 310 rotates, the central tube 310 moves along the axial direction of the container body 100.

[0060] Specifically, an inclined guide rail groove 400 is provided on the outer wall of the central tube 310, and a convex post 410 is provided on the inner wall of the connection cover 210. The convex post 410 protrudes into the guide rail groove 400. When the central tube 310 is rotated, due to the inclined setting of the guide rail groove 400 and the convex post 410 being stuck in the guide rail groove 400, the central tube 310 needs to rotate while moving axially, thereby realizing the closing or opening of the sub-chamber through the axial movement of the central tube 310. It should be noted that the axial movement distance of the central tube 310 is the same as the axial projection distance of the guide rail groove 400. In another embodiment, the guide rail groove 400 can extend axially on the outer wall of the central tube 310, the convex post 410 protrudes on the inner wall of the connection cover 210, and slides in the guide rail groove 400, so that the central tube 310 can be directly pulled to move axially away from the container body 100. The settings of the guide rail groove 400 and the convex post 410 can ensure the moving direction of the central tube 310 and prevent deviation during the movement, which affects the sealing of the sub-chamber.

[0061] Among them, at least one set of guiding mechanisms can be provided. In this embodiment, two sets are provided, that is, two guide rail grooves 400 are arranged at intervals on the outer periphery of the central tube 310, and the inclined directions of the two guide rail grooves 400 are the same. The setting of the two guiding mechanisms makes the movement of the central tube 310 more stable.

[0062] Please refer to Figure 9 、 Figure 10 and Figure 11 In the embodiment of the present invention, an anti-rotation groove 311 is provided on the outer wall of the central tube 310. The first cover group 200 further includes a housing 500. The housing 500 is sleeved on the outer periphery of the central tube 310, and a limiting post 510 is provided on the inner wall of the housing 500. The limiting post 510 is clamped with the anti-rotation groove 311 to drive the central tube 310 to rotate by rotating the housing 500.

[0063] Specifically, a housing 500 is sleeved on the outer periphery of the central tube 310. A plurality of limiting posts 510 are arranged at intervals along the circumferential direction on the inner wall of the housing 500. A plurality of anti-rotation grooves 311 are provided on the outer wall of the central tube 310. The anti-rotation grooves 311 are arranged at intervals. The limiting posts 510 can be correspondingly inserted into the intervals between adjacent anti-rotation grooves 311. When the housing 500 is rotated, due to the settings of the limiting posts 510 and the anti-rotation grooves 311, the central tube 310 is driven to rotate together. And due to the settings of the guide rail groove 400 and the convex post 410, when the central tube 310 rotates, it can drive the central tube 310 to move axially to realize the sealing and opening of the sub-chamber. Among them, the limiting posts 510 extend axially, and the anti-rotation grooves 311 are provided on the outer periphery of the end of the central tube 310 away from the container body 100.

[0064] Please refer to Figure 10 and Figure 11, in an embodiment of the present invention, the packaging container further includes an anti-theft ring 600. The anti-theft ring 600 is provided at one end of the outer shell 500 close to the container body 100 and is arranged along the circumferential direction of the outer shell 500. The anti-theft ring 600 is point-connected to the outer shell 500. The inner wall of the anti-theft ring 600 is snap-connected to the connection cover 210 so that when the outer shell 500 is rotated, the outer shell 500 is disconnected from the anti-theft ring 600.

[0065] Specifically, the anti-theft ring 600 is of an annular structure and is installed at one end of the outer shell 500 close to the container body 100. At least one connection point 610 is provided at an interval between the anti-theft ring 600 and the outer shell 500. The connection point 610 is designed as a common fracture point and has relatively weak structural strength. The same material as that of the anti-theft ring 600 can be used to form a thin wall by reducing its thickness to make it relatively fragile. When a rotational force is applied, stress concentration occurs at the thin wall, resulting in fracture at that place. Multiple positioning teeth 620 are provided at intervals on the inner wall of the anti-theft ring 600. Multiple positioning grooves 240 are provided at intervals on the outer circumference of one end of the connection cover 210 outside the accommodation cavity. The positioning teeth 620 are snap-connected in the positioning grooves 240. Through the arrangement of the positioning teeth 620 and the positioning grooves 240, the anti-theft ring 600 and the connection cover 210 are snap-connected to maintain a relatively stationary state. Before the first use, the anti-theft ring 600 is connected to the outer shell 500. When used for the first time, the outer shell 500 is rotated. Since the anti-theft ring 600 and the connection cover 210 remain stationary, when the outer shell 500 is forcibly rotated, the connection point 610 is fractured. At this time, the anti-theft ring 600 no longer affects the rotation of the outer shell 500. Through the arrangement of the anti-theft ring 600, an obvious visual indication can be provided for the user. If the anti-theft ring 600 remains connected, it proves that the packaging container has not been opened. If the anti-theft ring 600 is disconnected from the outer shell 500, it proves that the packaging container has been opened, and even if the outer shell 500 is re-closed, the connection between the outer shell 500 and the anti-theft ring 600 cannot be restored, with relatively high safety performance. In addition, the structure has a high degree of visualization, and the user can easily confirm whether the packaging is intact, improving the usage experience.

[0066] Please refer to Figure 5 , Figure 6 and Figure 8 , in an embodiment of the present invention, the first cover group 200 further includes a mounting seat 220 and a connecting plate 230. The mounting seat 220 is provided in the accommodation cavity. A plurality of connecting plates 230 are provided, and the plurality of connecting plates 230 are arranged at intervals along the circumferential direction of the connection cover 210, with one end connected to the connection cover 210 and the other end connected to the mounting seat 220. The gap between two adjacent connecting plates 230 is configured as a communication port 201. In the first state, the end of the central tube 310 abuts against the mounting seat 220 to block the communication port 201.

[0067] Specifically, an installation base 220 and a connecting plate 230 are further provided in the accommodation cavity. The connecting plate 230 is used to connect the installation base 220 and the connecting cover 210. One end of the connecting cover 210 in the accommodation cavity is close to the inner wall of the necking 110 and is coaxially arranged with the necking 110. A first annular portion 222 protrudes from the edge of the installation base 220. One end of the connecting plate 230 is connected to the outer periphery of the connecting cover 210, and the other end is connected with a second annular portion 260. And a plurality of connecting plates 230 are provided, that is, a plurality of connecting plates 230 are provided between the second annular portion 260 and the connecting cover 210, and the plurality of connecting plates 230 are arranged at intervals in the circumferential direction. The second annular portion 260 is inserted between the first annular portion 222 and the installation base 220, and a groove is arranged along the circumferential direction on the outer periphery of the second annular portion 260. A protrusion is arranged along the circumferential direction on the inner wall of the first annular portion 222, and the protrusion is clamped in the groove, that is, the connecting rod is connected to the installation base 220 through the connecting plate 230 and the second annular portion 260; since the connecting plates 230 are arranged at intervals, a gap is formed between adjacent spacers, and this gap is configured as a communication port 201. The part of the central tube 310 extending into the accommodation cavity, from the part close to the opening to the part far from the opening, its outer wall is sequentially connected to the inner wall of the connecting cover 210 through a guiding assembly and is in contact with the inner wall of the connecting plate 230. The end of the central tube 310 abuts against the installation base 220. At this time, the central tube 310, the connecting plate 230 and the installation base 220 form a sealed sub-cavity. When the outer shell 500 is rotated to drive the central tube 310 to rotate, due to the setting of the convex column 410 on the connecting cover 210, the central tube 310 moves axially while rotating. According to the direction of the inclination of the guide rail groove 400, when the central tube 310 moves in the direction away from the accommodation cavity, the central tube 310 moves along the connecting plate 230 and gradually moves until the end of the central tube 310 is far from the installation base 220. When it moves to the gap between adjacent connecting plates 230, at this time the sub-cavity is no longer sealed and communicates with the accommodation cavity, and the solution in the sub-cavity flows from the gap between the connecting plates 230 into the accommodation cavity and is mixed with the solution in the accommodation cavity.

[0068] Among them, such as Figure 5 and Figure 6As shown, the connecting cover 210 includes a first cover portion 211 and a second cover portion 212. Both the first cover portion 211 and the second cover portion 212 are annularly arranged. The first cover portion 211 is located in the accommodating cavity and fits against the inner wall of the necking 110. The convex post 410 is provided on the inner wall of the first cover portion 211. One end of the central tube 310 extending into the accommodating cavity sequentially passes through the first cover portion 211 and cooperates with the mounting seat 220. Moreover, the guide rail groove 400 on the central tube 310 cooperates with the convex post 410 on the first cover portion 211. The second cover portion 212 is sleeved on the outer periphery of the necking 110, and the first cover portion 211 and the second cover portion 212 are connected at the end of the necking 110. Specifically, internal threads are provided on the inner wall of the second cover portion 212, external threads are provided on the outer periphery of the necking 110, and limiting teeth 250 are provided on the inner wall of the end of the second cover portion 212. A convex ring 120 protrudes from the outer periphery of the end of the necking 110 close to the container body 100. Limiting grooves 121 are arranged at intervals along the circumferential direction of the convex ring 120. The limiting teeth 250 are inserted into the limiting grooves 121 so that the connecting cover 210 can be immovable relative to the container body 100. Specifically, during connection, the connecting cover 210 is moved from the opening end towards the container body 100. The first cover portion 211 extends into the interior of the accommodating cavity. One end of the second cover portion 212 provided with the limiting teeth 250 first approaches the external threads. Since the inner diameter of the end provided with the limiting teeth 250 is larger, when it approaches the convex ring 120, at this time, the internal thread portion of the second cover portion 212 cooperates with the external thread of the necking 110. By rotating the second cover portion 212, the connecting cover 210 is threadedly connected to the container body 100, and the end of the second cover portion 212 is clamped and cooperated with the limiting grooves 121 on the convex ring 120 through the limiting teeth 250, so that the connecting cover 210 has the effect of preventing reverse rotation and avoiding the separation of the connecting cover 210 from the container body 100. The connecting plate 230 connects the first cover portion 211 and the second annular portion 260 in the accommodating cavity. The positioning groove 240 is provided on the outer periphery of the second cover portion 212 for cooperating with the positioning teeth 620 on the inner wall of the anti-theft ring 600.

[0069] Please refer to Figure 3 and Figure 12 , in the embodiment of the present invention, the mounting seat 220 has a through hole 221. The packaging container further includes a pump seat 700 and a pump core 710. One end of the pump seat 700 extends into the accommodating cavity and communicates with the through hole 221 of the mounting seat 220, and the other end is outside the accommodating cavity and is clamped to the central tube 310. The pump core 710 is installed in the pump seat 700, and one end extending into the accommodating cavity passes through the through hole 221 and contacts the liquid in the accommodating cavity.

[0070] Specifically, a through hole 221 is provided at the axial center position of the mounting base 220. The pump base 700 is arranged inside the central tube 310 and is coaxially arranged with the central tube 310. One end of the pump base 700 is inserted into the through hole 221 in the accommodation cavity, and the accommodation cavity is communicated through the through hole 221. An annular groove is provided on the other end facing the opening side, and the central tube 310 is clamped in the annular groove to achieve clamping with the pump base 700. A pump core 710 is arranged in the pump base 700. One end of the pump core 710 passes through the pump base 700 and the through hole 221 and extends into the accommodation cavity to contact the liquid in the accommodation cavity, and the other end is responsible for sucking out the liquid in the accommodation cavity. Specifically, the pump core 710 is pressed by structures such as a pump head, so that the piston in the pump core 710 moves towards the accommodation cavity, thereby compressing the spring to generate negative pressure. The negative pressure is transmitted to the accommodation cavity through the pump base 700 and the through hole 221, so that the solution is sucked into the pump core 710. During the pressing process, the interface is tightly sealed, which can prevent external air and pollutants from entering the container interior, prevent the solution from being contaminated, affect the purity of the solution, and reduce the risk of deterioration or failure caused by direct contact.

[0071] Please refer to Figure 3 , in the embodiment of the present invention, the packaging container further includes a pressing cover 800. The pressing cover 800 has a liquid outlet pipe 810. One end of the liquid outlet pipe 810 is inserted into the pump core 710, and the other end is communicated outside the accommodation cavity; convex ribs 820 are provided on the inner wall of the pressing cover 800. A plurality of convex ribs 820 are provided and are arranged at intervals along the circumferential direction of the pressing cover 800. The convex ribs 820 extend axially, and in the first state, the convex ribs 820 abut against the limiting posts 510.

[0072] Specifically, a pressing cover 800 is provided at one end of the pump core 710 away from the accommodating cavity. The pressing cover 800 is connected to the pump core 710 through a liquid outlet pipe 810. When the pressing cover 800 is pressed, the solution in the pump core 710 enters the liquid outlet pipe 810 and then flows to the outside. Specifically, a plurality of ribs 820 are arranged at intervals along the circumferential direction on the inner wall of the pressing cover 800. The ribs 820 extend axially. The outer shell 500 is sleeved not only on the outer periphery of the central tube 310 but also on the outer periphery of the pressing cover 800. One end of the rib 820 close to the accommodating cavity cooperates with the limiting post 510 in the outer shell 500. When in the first state, the rib 820 abuts against the limiting post 510. At this time, the pressing cover 800 is inside the outer shell 500. Due to the arrangement of the limiting post 510, it is impossible to press the pressing cover 800 in the direction of the container body 100. When the packaging container is not in use, if it is placed in a bag or a suitcase, it can be prevented from colliding with other items and causing the solution to overflow or be wasted due to the pressing of the pressing cover 800. When the solution is needed, the outer shell 500 is rotated. The outer shell 500 drives the central tube 310 to move away from the container body 100 while rotating. The central tube 310 drives the pump base 700 to move. The pump base 700 drives the pump core 710 to move. And the pump core 710 drives the pressing cover 800 to move away from the container body 100. At this time, the pressing cover 800 moves outside the outer shell 500. The rib 820 is away from the limiting post 510, and there is a certain gap between the rib 820 and the limiting post 510. Thus, it is possible to press the pressing cover 800 in the direction of the container body 100. The solution enters the liquid outlet nozzle 830 through the pump core 710. After use, the outer shell 500 is rotated in the reverse direction. The central tube 310 drives the pump base 700 to move towards the accommodating cavity. Since the pump core 710 is clamped with the liquid outlet pipe 810, the pressing cover 800 moves together with the central tube 310 until one end of the guide rail groove 400 close to the pressing cover 800 is connected to the convex column 410. At this time, the pressing cover 800 returns to the inside of the outer shell 500, and the rib 820 abuts against the limiting post 510 again to prevent liquid leakage due to accidental contact.

[0073] Please refer to Figure 1 and Figure 3 In the embodiment of the present invention, one side of the outer shell 500 has a notch 520. The pressing cover 800 is further provided with a liquid outlet nozzle 830. The liquid outlet nozzle 830 is communicated with the liquid outlet pipe 810, and in the first state, the liquid outlet nozzle 830 is arranged at the notch 520.

[0074] Specifically, a liquid outlet nozzle 830 is protrudingly provided on one side of the pressing cover 800. The liquid outlet nozzle 830 is connected to the liquid outlet pipe 810. In the first state, the pressing cover 800 is located inside the outer shell 500, and the liquid outlet nozzle 830 is exactly clamped at the notch 520 of the outer shell 500. Through the setting of the notch 520, the liquid outlet nozzle 830 can be exactly accommodated when not in use, so that the surface and side of the liquid outlet nozzle 830 are flush with the outer shell 500 without protruding, thus maintaining the neatness and smoothness of the appearance, and can also prevent accidental touching of the liquid outlet nozzle 830, effectively avoiding damage or liquid leakage problems caused by accidental collision. In addition, the liquid outlet nozzle 830 is provided on one side of the pressing cover 800, so that the solution flows out from the side of the pressing cover 800, which can more easily control the flow direction of the solution, reduce the probability of the solution dripping around or on the top of the packaging container, improve the user experience, and pressing from above and discharging the solution from the side is more in line with the ergonomic principle and is more comfortable to use.

[0075] Please refer to Figure 2 , in the embodiment of the present invention, the packaging container further includes a soft rubber plug 840, and the soft rubber plug 840 is inserted into the liquid outlet nozzle 830.

[0076] Specifically, when the liquid outlet nozzle 830 is not in use, a soft rubber plug 840 can be inserted into the liquid outlet nozzle 830. The material of the soft rubber plug 840 can be rubber, which has a certain elasticity. After being inserted into the liquid outlet nozzle 830, it can closely adhere to the inner wall of the liquid outlet nozzle 830, providing a good sealing effect. The setting of the soft rubber plug 840 effectively blocks impurities such as dust and microorganisms in the external air from entering the liquid outlet nozzle 830, avoiding the possibility that these pollutants may contaminate or deteriorate the solution and ensuring the use effect. When the liquid outlet nozzle 830 needs to be used, the soft rubber plug 840 can be pulled out of the liquid outlet nozzle 830 to restore the normal solution outflow function. The structure of the soft rubber plug 840 is simple, and the insertion or extraction operation can be easily performed, increasing the convenience and safety of use. In addition, the setting of the soft rubber plug 840 can also reduce the risk of solution waste or leakage caused by accidentally turning out the central tube 310 and then pressing the pressing cover 800.
