Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging technology, specifically to a paste packaging container with an improved drive structure. Background Technology

[0002] Deodorant balms, lipsticks, and other cream-based cosmetics are easy to carry and use anytime, anywhere. Applied to the hands, ears, mouth, and other areas, they emit a fresh and pleasant fragrance, enhancing one's life and appearance. However, the storage of cosmetic creams is usually in sealed bottles or tubes, making it difficult to accurately control the amount dispensed each time. Furthermore, when the remaining cream in the bottle is low, it is difficult to remove the excess, easily leading to waste.

[0003] To address the aforementioned issues, Chinese utility model patent CN202322282748.2 (publication number CN220616556U) discloses a "Deodorant Packaging for Easy Disassembly and Recycling After Consumption." The inner sleeve includes a cylindrical body extending vertically and a bottom plate horizontally disposed within the cylinder, with the bottom plate and cylinder together forming an accommodating space. The lifting mechanism includes a lifting platform horizontally disposed above the bottom plate and a drive assembly for driving the lifting platform to move vertically within the inner sleeve.

[0004] The drive assembly includes a lifting rod, a screw, and a grip. The top of the lifting rod passes through a perforation in the base plate and connects to the lifting platform. The screw is inserted into the lifting rod and the two are threaded together. The grip is located at the bottom of the screw and is used to rotate the screw. By rotating the screw through the grip, the lifting rod moves upward, and the lifting platform moves upward accordingly, pushing the cream upward for easy access by the user.

[0005] In this patent, the lifting platform is raised and lowered by rotating the screw to squeeze the cream. Because of the screw rotation, the cream rises slowly, making it easier to control the amount squeezed out. Also, when there is little cream left, the cream is squeezed to the position near the bottle opening, making it easy for the user to take it.

[0006] The lifting stroke of the lifting platform (equivalent to the lifting plate below) in this patent depends on the length of the threaded engagement between the lifting rod and the screw. This means that in order for the lifting platform to have a large stroke to remove the cream from the container, the length of the threaded engagement between the lifting rod and the screw needs to be relatively long. As can be seen from the figure, the lifting rod and the screw are located below the inner sleeve's accommodating space. If the length of the lifting rod and the screw is too long, the height of the deodorant packaging will be too large, making it inconvenient to carry. If the size of the packaging is fixed, the space occupied by the drive component will be large, which will result in a smaller accommodating space for the cream and a smaller amount of cream that can be held. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a paste packaging container with an improved drive structure that can hold a large amount of paste, in light of the current state of the technology.

[0008] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a paste packaging container with an improved driving structure, comprising...

[0009] The outer shell is vertically continuous.

[0010] The inner shell is vertically continuous and located within the outer shell;

[0011] A movable plate is horizontally disposed in the inner shell and can move up and down relative to the inner shell. The inner shell and the movable plate form a receiving space with an open top for containing the ointment.

[0012] The drive structure is located below the moving board;

[0013] The characteristic is that the driving structure includes

[0014] The first screw extends vertically;

[0015] The drive assembly can drive the first screw to rotate circumferentially and also drive the first screw to move axially.

[0016] The first lifting rod is sleeved on the first screw and the two are threaded together, so that the first lifting rod can move vertically, and the top of the first lifting rod abuts against or is connected to the moving plate.

[0017] The drive assembly can have various structural forms, such as simultaneously configuring a push rod motor and a gear motor. The push rod motor pushes the first screw to move axially, and the gear motor drives the first screw to rotate circumferentially. However, such a structure is complex and costly. Preferably, the drive assembly includes a second screw and a second lifting rod.

[0018] The second screw extends vertically and can rotate about its axis;

[0019] The second lifting rod is sleeved outside the second screw and the two are threaded together, so that the inner shell of the second lifting rod can move vertically;

[0020] The first screw has a stop that abuts against the second lifting rod and is pushed upward by the second lifting rod. The first screw is also sleeved on the outside of the second screw, and the first and second screws are constrained together circumferentially. The first lifting rod and the second lifting rod are also constrained together circumferentially. When the second screw rotates, the second lifting rod moves vertically, pushing the first screw to move vertically. Since the first screw and the second screw are relatively fixed relative to each other circumferentially, the second screw drives the first screw to rotate. In this way, the first screw can simultaneously rotate circumferentially and move axially.

[0021] As can be seen from the above, the second lifting rod and the first screw are relatively fixed in the vertical direction, but can generate relative displacement in the circumferential direction. In order to achieve this solution, the first screw includes a small diameter part and a large diameter part arranged and connected from top to bottom. The inner diameter of the large diameter part is larger than the inner diameter of the small diameter part, thus forming a step between the two. The step surface is the stop. The second lifting rod is inserted into the large diameter part and abuts against the stop. The peripheral wall of the large diameter part is provided with a sliding groove extending along its circumference. The second lifting rod is provided with a slider that slides along the sliding groove, and the slider is vertically constrained in the sliding groove.

[0022] To facilitate vertical movement of the first and second lifting rods, a limiting cylinder connected to the second lifting rod is provided around its outer periphery. The limiting cylinder, the first lifting rod, the first screw, and the second screw are arranged sequentially from the outside to the inside. A connecting member is provided in the outer shell below the inner shell. The limiting cylinder is inserted into the connecting member and fixed relative to the connecting member in the circumferential direction. The first lifting rod and the limiting cylinder are fixed relative to each other in the circumferential direction.

[0023] In order to achieve relative fixation of the limiting cylinder and the connecting piece in the circumferential direction and with a simple structure, one of the limiting cylinder and the connecting piece is provided with a first limiting groove, and the other of the limiting cylinder and the connecting piece is provided with a first limiting block. The first limiting groove extends vertically, and the first limiting block is embedded in the first limiting groove.

[0024] To achieve relative fixation of the first lifting rod and the limiting cylinder in the circumferential direction, and with a simple structure, one of the first lifting rod and the limiting cylinder is provided with a third limiting groove, and the other of the first lifting rod and the limiting cylinder is provided with a third limiting block. The third limiting groove extends vertically, and the third limiting block is embedded in the third limiting groove.

[0025] To achieve relative fixation of the first screw and the second screw in the circumferential direction, and with a simple structure, one of the first screw and the second screw is provided with a second limiting groove, and the other of the first screw and the second screw is provided with a second limiting block. The second limiting groove extends vertically, and the second limiting block is embedded in the second limiting groove.

[0026] To facilitate the rotation of the second screw, the drive structure also includes a rotating seat located below the outer casing. The bottom of the second screw is fixedly connected to the rotating seat, which serves as a base. The rotating seat can rotate relative to the outer casing around the axis of the second screw. The rotating seat not only facilitates the rotation of the second screw but also serves as a base for the ointment packaging container.

[0027] To save costs, the movable plate and the first lifting rod are detachably bound together, and the inner shell is detachably located inside the outer shell. After the ointment is used up, the outer shell can be removed first, and the movable plate and inner shell can be detached from the outer shell. After new ointment is installed, it can be matched with the first lifting rod, and then the outer shell can be installed. The ointment packaging container can then be reused, saving costs.

[0028] To facilitate detachment between the first lifting rod and the movable plate, preferably, the top of the first lifting rod is connected to a connecting cylinder, and the bottom of the movable plate is formed with a vertically extending annular body. The annular body has a groove extending through its bottom edge, and the annular body surrounds the outer periphery of the connecting cylinder. The peripheral wall of the connecting cylinder has a locking block that can be inserted into or disengaged from the locking groove. The inner shell and movable plate are installed downwards towards the connecting cylinder until the locking block is engaged in the locking groove, thus completing the installation of the first lifting rod and the movable plate. When detachment is required, the inner shell and movable plate are moved upwards.

[0029] Compared with the prior art, the advantages of this utility model are as follows: The driving component of this utility model can drive the first screw to rotate circumferentially and move axially at the same time. While the first screw rotates circumferentially, causing the first lifting rod to rise and fall, the first screw itself can also move axially, thus further extending the travel of the first lifting rod. Compared with the solution where the first screw can only rotate circumferentially, the first lifting rod of this utility model has a longer travel when the length of the first screw is the same. Specifically applied to the ointment packaging container of this application, the length of the first lifting rod and the first screw of this application is relatively short, which not only has sufficient travel but also occupies less space. Thus, with a fixed packaging container size, the accommodating space can be made larger, and more ointment can be held. Attached Figure Description

[0042] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0043] like Figures 1-11 As shown, the ointment packaging container with improved drive structure in this preferred embodiment includes an inner shell 12, a connector 11, a drive structure, a top cover 9, and an outer shell 7.

[0044] The outer shell 7 is vertically continuous, and the inner shell 12 is vertically continuous and located within the outer shell 7. The top of the outer shell 7 is provided with a pressing part 71 that can press against the top of the inner shell 12. The outer shell 7 is provided with a connecting member 11 located below the inner shell 1. The top cover 9 is detachably mounted on the top of the outer shell 7, and the top cover 9 and the outer shell 7 are detachably connected together by existing latching protrusions 70 and latching grooves 91.

[0045] The movable plate 2 is horizontally disposed in the inner shell 12. The movable plate 2 can move up and down relative to the inner shell 12. The inner shell 1 and the movable plate 2 form a container space 21 with an open top for containing the paste.

[0046] The drive structure is located below the movable plate 2 and is driven by the movable plate 2 to move the movable plate 2 up and down. The drive structure includes a first screw 31, a first lifting rod 32, a drive assembly, and a rotating seat 33. The drive assembly includes a second screw 34 and a second lifting rod 35.

[0047] The first screw 31 extends vertically, with its axial direction being vertical and its circumferential direction being the direction around its axis. The drive assembly drives the first screw 31 to rotate circumferentially and move axially simultaneously. This is achieved as follows: the second screw 34 extends vertically and can rotate around its axis; the second lifting rod 35 is sleeved on the outside of the second screw 34 and the two are threadedly connected; the second lifting rod 35 can only move vertically; the first screw 31 has a stop 311 that abuts against the second lifting rod 35 and is pushed upward by the second lifting rod 35; the first screw 31 is also sleeved on the outside of the second screw 34, and the first screw 31 and the second screw 34 are constrained together circumferentially. The threaded connection between the screw and the lifting rod can be referenced to the screw-nut drive system.

[0048] Specifically, the first screw 31 includes a small-diameter portion 312 and a large-diameter portion 313 arranged and connected sequentially from top to bottom. The inner diameter of the large-diameter portion 313 is larger than the inner diameter of the small-diameter portion 312, thus forming a step between the two. This step surface is the stop portion 311. The second lifting rod 35 is inserted into the large-diameter portion 313 and abuts against the stop portion 311. The peripheral wall of the large-diameter portion 313 is provided with a sliding groove 314 extending along its circumference. The second lifting rod 35 is provided with a slider 351 that slides along the sliding groove 314. In this way, the second lifting rod 35 and the first screw 31 can generate relative displacement in the circumferential direction, and the slider 351 is vertically constrained in the sliding groove 314, so as to realize that the second lifting rod 35 and the first screw 31 are relatively fixed in the vertical direction, driving the first screw 31 to move in the vertical direction.

[0049] The first lifting rod 32 is sleeved on the first screw 31 and the two are threaded together, so that the first lifting rod 32 can move vertically. The top of the first lifting rod 32 abuts against or is connected to the moving plate 2 to drive the moving plate 2 to move vertically. The first lifting rod 32 and the second lifting rod 35 are constrained together in the circumferential direction.

[0050] The specific working process is as follows: When the second screw 34 rotates, the second lifting rod 35 moves vertically, pushing the first screw 31 to move vertically. Since the first screw 31 and the second screw 34 are relatively fixed circumferentially, the second screw 34 then drives the first screw 31 to rotate, thus achieving simultaneous circumferential rotation and axial movement of the first screw 31. In this way, while the first screw 31 rotates circumferentially, causing the first lifting rod 32 to rise and fall, the first screw 31 itself can also move axially, further extending the travel of the first lifting rod 32. Compared to the scheme where the first screw 31 can only rotate circumferentially, with the same length of the first screw 31, the first lifting rod 32 of this invention has a longer travel. Specifically applied in the ointment packaging container of this application, with a fixed packaging container size, this allows the accommodating space 21 to be made larger, enabling it to hold more ointment.

[0051] The second lifting rod 35 is surrounded by a limiting cylinder 352 connected to it. The limiting cylinder 352, the first lifting rod 32, the first screw 31 and the second screw 34 are arranged sequentially from the outside to the inside. The limiting cylinder 352 is inserted into the connector 11 and fixed relative to the connector 11 in the circumferential direction so that the second lifting rod 35 can only move vertically. The first lifting rod 32 and the limiting cylinder 352 are fixed relative to each other in the circumferential direction so that the first lifting rod 32 can only move vertically.

[0052] To achieve relative fixation of the limiting cylinder 352 and the connecting member 11 in the circumferential direction, one of the limiting cylinder 352 and the connecting member 11 is provided with a first limiting groove 41, and the other of the limiting cylinder 352 and the connecting member 11 is provided with a first limiting block 42. The first limiting groove 41 extends vertically, and the first limiting block 42 is embedded in the first limiting groove 41. In this embodiment, the first limiting groove 41 is provided on the connecting member 11, and the first limiting block 42 is provided on the limiting cylinder 352, so that the limiting cylinder 352 can only move vertically, and the second lifting rod 35 can only move up and down.

[0053] One of the first lifting rod 32 and the limiting cylinder 352 is provided with a third limiting groove 51, and the other of the first lifting rod 32 and the limiting cylinder 352 is provided with a third limiting block 52. The third limiting groove 51 extends vertically, and the third limiting block 52 is embedded in the third limiting groove 51. In this embodiment, the third limiting groove 51 is provided on the limiting cylinder 352, and the third limiting block 52 is provided on the first lifting rod 32. Because the limiting cylinder 352 can only move vertically, the first lifting rod 32 can only move vertically. That is, both the first lifting rod 32 and the second lifting rod 352 can only move vertically, and the two are relatively fixed in the circumferential direction.

[0054] One of the first screw 31 and the second screw 34 is provided with a second limiting groove 61, and the other of the first screw 31 and the second screw 34 is provided with a second limiting block 62. The second limiting groove 61 extends vertically, and the second limiting block 62 is embedded in the second limiting groove 61. In this embodiment, the second limiting block 62 is provided on the first screw 31, and the second limiting groove 61 is provided on the second screw 34.

[0055] The rotating base 33 is located below the outer casing 7. The bottom of the second screw 34 is fixedly connected to the rotating base 33. The rotating base 33 serves as a base below the outer casing 7 and can rotate relative to the outer casing 7 around the axis of the second screw 34. The rotating base 33 not only facilitates driving the second screw 34 to rotate, but also serves as a base for the ointment packaging container.

[0056] The rotating seat 33 is also provided with a connecting part 331 connected to the connecting member 11. The outer wall surface of the connecting part 331 is a first inclined surface 332 that slopes outward from top to bottom. The inner peripheral wall of the connecting member 11 is provided with a limiting rib 113. The inner wall surface of the limiting rib 113 slopes outward from top to bottom to cooperate with the first inclined surface 332, so that the connecting part 331 can pass over the limiting rib 113 and rest on the limiting rib 113, and the connecting part 331 can slide along the limiting rib 113.

[0057] The movable plate 2 and the first lifting rod 32 are detachably bound together, and the inner shell 12 is detachably located in the outer shell 7.

[0058] This embodiment enables the first lifting rod 32 and the movable plate 2 to be detached in the following way: A connecting cylinder 8 is connected to the top of the first lifting rod 32, and a vertically extending annular body 22 is formed at the bottom of the movable plate 2. The annular body 22 has a groove 221 extending through its bottom edge. The annular body 22 surrounds the outer periphery of the connecting cylinder 8, and a fastening block 82 is provided on the peripheral wall of the connecting cylinder 8, which can be inserted into or disengaged from the groove 221. The inner shell 12 and the movable plate 2 are installed downwards towards the connecting cylinder 8 until the fastening block 82 is engaged in the groove 221, thus achieving the installation of the first lifting rod 32 and the movable plate 2. When detachment is required, the inner shell 12 and the movable plate 2 are moved upwards.

[0059] There is no connection between the outer shell 7 and the inner shell 12. The outer shell 7 can be detached from the inner shell 12. However, in this embodiment, the outer shell 7 and the connector 11 can be detachably connected: the inner peripheral wall of the outer shell 7 is provided with a groove 72, and the connector 11 is provided with a locking block 111 that can be locked in the groove 72. The outer wall surface of the locking block 111 is an inclined surface 112 that slopes outward from top to bottom so that it can enter or exit the groove 72. The locking block 111 can be in the form of a buckle that can deflect inward and outward relative to the connector 11. The locking block 111 maintains the tendency to deflect outward.

[0060] After the ointment is used up, remove the top cover 9, forcefully remove the outer shell 7, remove the original inner shell 12 and the moving plate 2, place the new inner shell 12 containing the ointment on the connector 11, and fasten the fastener 82 into the fastener slot 221. Then reinstall the outer shell 7, and it can be reused without scrapping the entire packaging container, thus saving costs.

[0061] like Figure 9 , 10 As shown, the bottom of the limiting cylinder 352 and the second lifting rod 35 are connected by a connecting plate 353. The connecting plate 353 is provided with an arc-shaped guide groove 3531. The bottom plate of the rotating seat 33 is provided with a guide block 333 that slides along the guide groove 3531 to limit the rotation trajectory and stroke of the rotating seat 33.

[0062] The inner peripheral wall of the inner shell 12 is provided with a limiting rib 121, and the movable plate 2 can rest on the limiting rib 121. At this time, the movable plate 2 is in the lower limit position, such as... Figure 2 As shown; when the movable plate 2 is at the top opening of the inner shell 12, the movable plate 2 is in the upper limit position, as shown. Figure 11 The movable plate 2 shown is adjacent to the top opening of the inner shell 12.

[0063] In this embodiment, the rotating seat 33 includes a base plate 334 and a cylindrical body 335 extending upward from the periphery of the base plate 334. A connecting part 331 is located at the top of the cylindrical body 335, and a second screw 34 is located at the center of the base plate 334. The cylindrical body 335 and the base plate 334 are fixedly connected. Because the second screw 34 is the main load-bearing part, if the connection between the cylindrical body 335 and the base plate 334 is not firm and detachment occurs, it will affect the working reliability of the second screw 34. Therefore, the structure of Embodiment 2 is designed as follows.

[0064] Example 2

[0065] The difference between Example 2 and Example 1 is that the structure of the rotating seat in this example is different from that in Example 1.

[0066] like Figure 12 As shown, in this embodiment, the cylinder 335 and the bottom plate 334 are integrally formed, the connecting part 331 is provided on the mounting part 336, and the mounting part 336 is installed on the cylinder 335.
