Description

Technical Field

[0001] This utility model relates to the field of daily chemical products technology, and in particular to a daily chemical product and its packaging container and replacement device. Background Technology

[0002] Deodorant balms, lipsticks, and other solid or cream-based cosmetics are easy to carry and can be used anytime, anywhere. They can be applied to the hands, ears, mouth, and other parts of the body to emit a fresh and pleasant fragrance, beautifying people's lives and appearance.

[0003] For ease of carrying and use, ointment or solid daily chemical products are typically packaged in boxes, jars, or tubes. Existing replaceable ointment-based daily chemical products include a packaging container that works in conjunction with the product, and a replacement device installed within the packaging container. The replacement device is made of biodegradable materials. The packaging container usually includes a rotating lifting mechanism for ejecting or retrieving the daily chemical product from the replacement device. For example, in the packaging container disclosed in CN111874415A, a screw is fixedly mounted on the base, and the screw meshes with the base plate. When the base rotates, it drives the screw to rotate, which in turn moves the base plate along the screw, thereby moving the lifting platform axially. This ejects the cosmetic ointment from the replacement device for use or retrieves it for storage. In this structure, the maximum extension range of the lifting mechanism depends on the height of the screw. That is, in order to completely eject the deodorant for use, the height of the screw cannot be less than the height of the deodorant. This results in the packaging container being at least twice the size of the replacement device, making the overall packaging container large, space-consuming, and inconvenient to carry and use. Furthermore, when replacing the replacement device, the entire rotating lifting mechanism and the box body need to be disassembled before installation. The structure is complex, and the process of installing and replacing the replacement device is also very complicated, affecting the user experience.

[0004] Therefore, it is necessary to provide a paste or solid daily chemical product and its packaging container and replacement device that are simple in structure, small in size, and convenient to carry and use. Summary of the Invention

Detailed Implementation

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. The term "axial" refers to the direction of the central axis of the container body. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through specific circumstances.

[0036] Figure 1 This is a schematic diagram of the overall structure of the packaging container for daily chemical products according to an embodiment of the present utility model; Figure 2 This is an exploded structural diagram of a packaging container equipped with a replacement device according to an embodiment of the present invention.

[0037] Please see Figure 1 , Figure 2 , Figure 3b and Figure 4The daily chemical product packaging container provided in this embodiment includes a container body 4 and a lifting mechanism 101. The container body 4 has a first end 42, a second end 43, and a cavity 47 for accommodating a replacement device 20. The first end 42 of the container body 4 is an open end, through which paste or solid daily chemical products enter and exit. A limiting component 5 is provided at the first end 42 of the container body 4 to fix the replacement device 20 in the cavity 47 of the container body 4. The lifting mechanism 101 includes a control unit 1 and a lifting assembly 123. The control unit 1 and the second end 43 of the container body 4 are movably connected. The lifting assembly 123 is composed of multiple interlocking and axially extendable tubular components. The control unit 1 and the lifting assembly 123 are driven and connected, and the lifting assembly 123 is controlled to extend and retract axially. The top end of the lifting assembly 123 can abut against the bottom of the replacement device 20 installed in the container body 4. The control unit 1 controls the lifting assembly 123 to extend and retract axially, thereby controlling the paste or solid daily chemical products in the replacement device 20 to move axially.

[0038] See also Figure 2 , Figure 3b and Figure 4 In one specific embodiment, the limiting component 5 is detachably connected to the container body 4. The inner diameter of at least one outlet end of the limiting component 5 is smaller than the outer diameter of the replacement device 20 and greater than or equal to the inner diameter of the replacement device 20, preferably equal to the inner diameter of the replacement device 20. This allows the limiting component 5 to both hold the top surface of the replacement device 20 and allow the paste or solid daily chemical product inside the replacement device 20 to enter and exit from the first end 42 of the container body 4. After the limiting component 5 is disassembled, the replacement device 20 can be inserted into or removed from the first end 42 of the container body 4, making the operation very simple and convenient. After the limiting component 5 is installed, the end face of the replacement device 20 is held by the limiting component 5, fixing the replacement device 20 in the cavity 47 of the container body 4. The replacement device 20 will not protrude from the opening end of the container body 4, thereby allowing the paste or solid daily chemical product inside the replacement device 20 to move axially relative to the replacement device 20, protruding from the first end 42 of the container body 4 for consumer use or retracting back into the replacement device 20 for storage.

[0039] Furthermore, both the limiting component 5 and the container body 4 are cylindrical. The first end 42 of the container body 4 has a first connecting part 44. The inner diameter of the first connecting part 44 is the same as the inner diameter of the container body 4, and the outer diameter of the first connecting part 44 is slightly smaller than the outer diameter of the container body 4. The limiting component 5 is matched and connected to the first connecting part 44. This connection can be an interference fit, a snap-fit ​​connection, or a spiral connection. If it is an interference fit, the material of the limiting component 5 and / or the first connecting part 44 is elastic. If it is a snap-fit ​​connection, the inner wall of the limiting component 5 and the outer wall of the first connecting part 44 can be fitted with grooves and protrusions. Alternatively, it can be a threaded rotation connection. This utility model does not impose any special restrictions on the connection method. Preferably, the outer diameter of the limiting component 5 is the same as the outer diameter of the container body 4. After installation, it forms a cylindrical shape with equal diameter, resulting in a simple and beautiful overall appearance.

[0040] See also Figure 3b , Figure 4 and Figure 7a In one embodiment, both the container body 4 and the control unit 1 are cylindrical. The second end 43 of the container body 4 has a second connecting portion 45. The outer wall of the second connecting portion 45 is provided with a first protrusion 451 or a first annular groove (not shown). The inner wall of the control unit 1 is provided with a matching second annular groove 12 or a second protrusion (not shown). The first protrusion 451 and the second annular groove 12 are matched and engaged, or the first annular groove and the second protrusion are matched and engaged to form a rotatable connection in the circumferential direction. The first protrusion 451 or the second protrusion can be a continuous annular protrusion or a plurality of discrete protrusions. During operation, the lifting assembly 123 is axially extended or retracted by rotating the control unit 1 clockwise or counterclockwise. Preferably, the outer diameter of the second connecting portion 45 is slightly smaller than the outer diameter of the container body 4, and the outer diameter of the control unit 1 is the same as the outer diameter of the container body 4. After installation, a cylindrical shape with equal diameter is formed.

[0041] See Figure 2 , Figure 3c , Figure 7a and Figure 8aThe lifting assembly 123 includes a drive tube 11 and a first lifting tube 2. The drive tube 11 and the bottom surface of the control unit 1 are integrally formed. When the control unit 1 rotates, it drives the drive tube 11 to rotate synchronously. The top end of the drive tube 11 is provided with a first slot 112, which gives the end of the control unit 1 radial compression elasticity. The outer surface of the drive tube 11 near the top is provided with a first thread 111 that is interrupted by the first slot 112. The inner surface of the first lifting tube 2 is provided with a first spiral groove 25 that matches the first thread 111. The first thread 111 and the first spiral groove 25 form a first spiral pair. Further, the outer diameter of the first thread 111 is equal to the inner diameter of the first spiral groove 25, so that the first thread 111... Without external force to rotate the control unit 1, it can be locked and stopped in the first spiral groove 25; furthermore, the inner diameter of the mounting port of the first lifting tube 2 is smaller than the outer diameter of the first thread 111, and there are two first slots 112, which are symmetrically distributed in the circumferential direction. The elasticity of the first slots 112 is used to fit the first lifting tube 2 onto the drive tube 11. When the control unit 1 is rotated, the drive tube 11 rotates and the first thread 111 moves along the first spiral groove 25, thereby causing the first lifting tube 2 to move axially; and a first stop 26 is provided at the bottom end of the first spiral groove 25. When the first thread 111 is rotated to the bottom, the first lifting tube 2 is locked and stops axial movement, and the first thread 111 is locked in the first spiral groove 25.

[0042] Further, see Figure 5c , Figure 8a and Figure 9 The lifting assembly 123 also includes a second lifting tube 3. A second slot 22 is provided at the top end of the first lifting tube 2, giving the end of the first lifting tube 2 radial compressibility. A second thread 21, interrupted by the second slot 22, is provided on the outer surface of the first lifting tube 2 near its top end. A second spiral groove 32, matching the second thread 21, is provided on the inner surface of the second lifting tube 3. The second thread 21 and the second spiral groove 32 constitute a second spiral pair. Furthermore, the outer diameter of the second thread 21 is equal to the inner diameter of the second spiral groove 32, allowing the second thread 21 to engage and remain in place without external force rotating the control unit 1. Within a spiral groove 25; furthermore, the inner diameter of the mounting opening of the second lifting tube 3 is smaller than the outer diameter of the second thread 21. There are two first slots 112, symmetrically distributed circumferentially. The elasticity of the second slot 22 is used to fit the second lifting tube 3 onto the outside of the first lifting tube 2. When the first lifting tube 2 rotates with the drive tube 11, the second thread 21 moves along the second spiral groove 32, thereby causing the second lifting tube 3 to move axially. The bottom end of the second spiral groove 32 is provided with a second stop 33. When the second thread 21 rotates to the bottom, the second lifting tube 3 is stuck and stops axial movement, and the second thread 21 is locked in the second spiral groove 32.

[0043] See Figure 4 and Figure 9 In one embodiment, the outer surface of the second lifting tube 3 is provided with a protruding rib 31 along the axial direction. A through hole 48 is provided in the middle of the bottom surface 46 of the container body 4. A guide tube 41 extends axially around the through hole 48. The guide tube 41 is provided with a guide groove 411 that matches the protruding rib 31. The guide tube 41 is sleeved on the outside of the second lifting tube 3, which plays the role of stabilizing, guiding and protecting the lifting assembly 123. During operation, it can prevent the paste or solid daily chemical products in the box body 201 from shaking or tilting, so that the paste or solid daily chemical products can move smoothly. The top end of the second lifting tube 3 passes through the through hole 48 and extends into the cavity 47 of the container body 4, abutting against the bottom 202 of the replacement device 20. The protruding rib 31 is inserted into the guide groove 411 and can move axially along the guide groove 411 through the through hole 48 into the cavity 47 of the container body 4, further preventing the paste or solid daily chemical products in the box body 201 from shaking or tilting, so that the paste or solid daily chemical products can move smoothly.

[0044] See Figures 3a-3c , Figure 4 and Figure 8a In the first embodiment, a radially outwardly extending flange 23 is provided at the bottom end of the first lifting tube 2. The flange 23 is used to support the second lifting tube 3. A radial protrusion 24 is provided on the outer surface of the flange 23. The outer diameter of the protrusion 24 is less than or equal to the inner diameter of the guide tube 41 and greater than the inner diameter of the through hole 48. When the protrusion 24 moves axially to the top of the drive tube 11, the protrusion 24 can be axially limited to the bottom surface 46 of the container body 4, further ensuring that the entire lifting assembly 123 remains stable and preventing the lifting assembly 123 from tilting or shaking, thereby ensuring that the daily chemical product paste or solid can move smoothly; the circumference of the protrusion 24 The width of the guide groove 411 is greater than its circumferential width, so that when the first lifting tube 2 rotates circumferentially, the protrusion 24 is prevented from getting stuck in the guide groove 411 and affecting the rotation. In this embodiment, the diameter of the through hole 48 is smaller than the inner diameter of the guide tube 41. The guide groove 411 does not penetrate the tube wall radially, but the guide groove 411 penetrates the bottom surface 46 and communicates with the through hole 48 axially, so that the protrusion 31 on the second lifting tube 3 can pass through the through hole 48 along the guide groove 411 and enter the cavity 47 of the container body 4. In this embodiment, the pitch and helix angle of the first spiral groove 25 and the second spiral groove 32 are the same. When the lifting assembly 123 is in Figure 3bIn the retracted state, when the control unit 1 is rotated, the drive tube 11 rotates. The rotation of the drive tube 11 causes the first thread 111 to move along the first spiral groove 25, thereby causing the first lifting tube 2 and the second lifting tube 3 to rise axially simultaneously. When the first thread 111 reaches the bottom end of the first spiral groove 25, the first lifting tube 2 stops moving axially due to the first stop 26 and rotates with the drive tube 11. After the first lifting tube 2 rotates, the second thread 21 moves along the second spiral groove 32, causing the second lifting tube 3 to continue rising axially. When the second thread 21 reaches the bottom end of the second spiral groove 32, it is stopped by the second stop 33. This position is the highest position that the lifting assembly 123 can rise to. Therefore, by using three stackable lifting tubes, the height is approximately twice that of existing screw lifting structures while occupying the same height space. Conversely, when the same lifting height is required, the height of the lifting assembly 123 in the retracted state can be halved, significantly reducing the volume of the packaging container 10, making the entire packaging container 10 compact and easy to carry and use.

[0045] See Figures 5a-5c 6a Figure 6b and Figure 8bIn the second embodiment, the guide groove 412 is a slotted structure that radially penetrates the wall of the guide tube 41. A radially outwardly extending flange 23 is provided at the bottom end of the first lifting tube 2. A radial protrusion 24 is provided on the outer surface of the flange 23. The protrusion 24 can move axially along the guide groove 412. The outer diameter of the protrusion 24 is larger than the outer diameter of the guide tube 41. When the protrusion 24 moves axially to the top of the drive tube 11, it is axially limited at the bottom surface 46 of the container body 4. Similar to the first embodiment, the guide groove 412 also axially penetrates the bottom surface 46 and communicates with the through hole 48, so that the protrusion 31 on the second lifting tube 3 can pass through the through hole 48 along the guide groove 412 and enter the cavity 47 of the container body 4. In this embodiment, the diameter of the through hole 48 can be the same as the inner diameter of the guide tube 41, and the radial dimension of the protrusion 24 can be larger than that in the first embodiment. The pitch of the second spiral groove 32 is smaller than the pitch of the first spiral groove 25. When the control unit 1 is rotated, the drive tube 11 rotates. Since the pitch of the second spiral groove 32 is smaller than the pitch of the first spiral groove 25, the force on the circumferential direction of the second spiral groove 32 is greater than that of the first spiral groove 25, causing the second thread 21 to move along the second spiral groove 32. This causes the protrusion 31 of the second lifting tube 3 to rise axially along the guide groove 412. When the second thread 21 reaches the bottom end of the second spiral groove 32, it is restricted by the second stop 33, and the control unit continues to rotate. 1. This allows the first thread 111 to continue moving along the first spiral groove 25, thereby causing the first lifting tube 2 to continue to rise axially. At this time, the protrusion 24 moves along the guide groove 412. When the first thread 111 turns to the bottom end of the first spiral groove 25, it is restricted by the first stop 26. The protrusion 24 is limited to the bottom surface 46 of the container body 4. This position is the highest position that the lifting assembly 123 can rise. Similarly, by using three stackable lifting tubes, the height is nearly twice that of the existing screw structure while occupying the same height space. Conversely, when the same lifting height is required, the height of the lifting assembly 123 in the retracted state can be halved, which greatly reduces the volume of the packaging container 10.

[0046] In other embodiments, those skilled in the art can adjust the number of retractable tubes constituting the lifting assembly 123 as needed based on the above implementation scheme. A similar mating structure can be used to set more lifting tubes for stacking assembly to reduce the volume occupied by the lifting assembly 123. This utility model does not impose any particular limitation on this.

[0047] Furthermore, a first groove (not shown) is provided on the protrusion 24, and a third protrusion matching the first groove is provided on the inner side of the bottom surface of the control unit 1. When the control unit 1 is rotated to the bottom, the third protrusion locks in the first groove in a one-way snap to prevent the control unit 1 from continuing to rotate. In use, it is unlocked by rotating in the opposite direction to allow the lifting assembly 123 to move axially.

[0048] See Figure 2 and Figure 5b The packaging container 10 also includes a container lid 6, the inner diameter of which matches the outer diameter of the container body 4. Preferably, the container lid 6 covers the container body 4 and part of the control body 1. The container lid 6 can be connected to the control body 1 or the container body 4 by means of a snap-fit ​​or threaded rotation connection. The container lid 6, the container body 4, and the control body 1 can be subjected to secondary processing such as anodizing, spraying, printing, and laser engraving to make the product more textured and beautiful, or to improve the operating feel.

[0049] Please see Figure 2 and Figure 10 This embodiment also provides a daily chemical product replacement device, which is used in conjunction with the packaging container 10 provided by this utility model. The replacement device 20 includes a box body 201 and a box bottom 202. The box body 201 has an open end 2011. The box bottom 202 and the box body 201 are separable. A second groove 2021 is formed by recessing the middle of the box bottom 202 towards the open end 2011. The box body 201 has a cavity for placing ointments or solid daily chemical products. Preferably, the box bottom 202 and the box body 201 are integrally formed. A cutting line 2022 is provided around the box bottom 202 near the box body 201. Under the action of external force, the box bottom 202 can be separated from the box body 201 along the cutting line 2022. In this embodiment, when the rotation control unit 1 and the second lifting tube 3 rise, they give the box bottom 202 an upward pushing force, and the box bottom 202 and the box body 201 separate. The lifting assembly 123 controls the bottom 202 of the container to move axially, thereby controlling the axial movement of the paste or solid daily chemical product on the bottom 202. The paste or solid daily chemical product extends beyond the second end 43 of the container body 4 and is available for consumer use. After use, the paste or solid daily chemical product is returned to the replacement device 20 for storage. The replacement device 20 also includes a lid, sealing film, or sleeve to seal the opening 2011 of the replacement device 20, protecting the unused daily chemical product in the replacement device 20 from contamination; the sealing components are removed during use.

[0050] Please see Figure 1 and Figure 2This embodiment also provides a daily chemical product, including the above-mentioned packaging container 10 and replacement device 20. The replacement device 20 contains a solid or paste-like daily chemical product. The opening end 2011 of the box body 201 is open and inserted into the cavity 47 of the container body 4. The opening end 2011 of the box body 201 is locked by the limiting component 5. The bottom of the box body 201 is locked on the bottom surface 46 of the container body 4. The top surface of the lifting component 123 abuts against the bottom 202 of the replacement device 20. The lifting component 123 can drive the solid or paste-like daily chemical product to move axially within the container body 4. Specifically, in this embodiment, the end of the third lifting tube 3 and the second groove 2021 of the bottom 202 of the box body 202 cooperate and abut. The shape and size of the second groove 2021 match the shape and size of the end of the third lifting tube 3 shown in FIG. 6, preventing the daily chemical product paste or solid in the box body 201 from shaking or tilting, so that the daily chemical product paste or solid can move smoothly. When the rotation control unit 1 moves the third lifting tube 3 along the axial direction, it causes the paste-like or solid daily chemical products to move relative to the box body 201, thereby exposing the paste-like or solid daily chemical products to the first end 42 of the container body 4 for consumer use, or returning them to the replacement device 20 for storage after use.

[0051] In other embodiments, the second groove 2021 of the box bottom 202 can be set as a protrusion, and the top of the lifting assembly 123 is provided with a groove that matches the protrusion, and the protrusion is inserted into the groove for cooperative movement.

[0052] The replacement device 20 for the paste or solid daily chemical products provided by this utility model is very simple: First, remove the limiting part 5 and take out the replacement device 20 after the paste or solid daily chemical product has been used up; then, take a new replacement device and remove the sealing part. The replacement device is the product after the paste or solid daily chemical product is put into the replacement device 20; that is, the replacement device is replaced; finally, put the empty replacement device 20 into the recycling bin for degradation or recycling.

[0053] The paste-like or solid daily chemical products described in this utility model include, but are not limited to, deodorant, lipstick, cream lip gloss, eyeshadow or powder. As long as they are paste-like or solid daily chemical products, the packaging container 10 and replacement device 20 provided in this utility model can be used.

[0054] In summary, the daily chemical products and their packaging containers and replacement devices provided by this utility model, by setting a lifting component in the packaging container, and the lifting component being composed of multiple interlocking and axially extendable tubes, the distance that can move axially is the sum of the axial lengths of the multiple tubes, can reduce the space occupied by the lifting component by a factor of two, thereby making the entire packaging container smaller in size, easier to carry and use, and improving the user experience; the limiting component and the container body are detachably connected, the overall structure is simple, and the replacement is very simple and convenient.
