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 usually packaged in boxes, jars, or tubes. Existing replaceable ointment-based daily chemical products...

[0004] This includes a packaging container used in conjunction with a replacement device installed within the packaging container. The replacement device is made of biodegradable material. The packaging container typically includes a rotating lifting mechanism for ejecting or retrieving the cosmetic 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 a 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 product 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, to fully eject the deodorant, the screw height cannot be lower than the height of the deodorant, resulting in a packaging container volume at least twice that of the replacement device. This leads to a large overall packaging container volume, occupying a lot of space and making it inconvenient to carry and use. Furthermore, replacing the replacement device requires disassembling the entire rotating lifting mechanism and the container body before installation, making the structure complex and the installation and replacement process very complicated, impacting the user experience.

[0005] 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. Utility Model Content

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through specific circumstances.

[0041] 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.

[0042] Please see Figure 1 , Figure 2 , Figure 7a 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 rotatably connected. Component 123 includes a screw 11, an inner threaded sleeve 2, and an outer threaded sleeve 3 disposed on the control unit 1. The end of the inner threaded sleeve 2 is provided with a radially compressible and circumferentially disconnected second outer thread 211. The second outer thread 211 is matched and screwed into the second inner thread 32 inside the outer threaded sleeve 3. Rotating the control unit 1 causes the screw 11 to drive the inner threaded sleeve 2 and the outer threaded sleeve 3 to extend and retract axially. The top of the lifting component 123 is provided with a lifting platform 34. The lifting platform 34 can abut against the bottom of the replacement device 20 installed in the container body 4, thereby controlling the paste or solid daily chemical products in the replacement device 20 to move axially.

[0043] See also Figure 2 In one specific embodiment, the limiting component 5 is threadedly connected to the container body 4, the first end 42 of the container body 4 has a first connecting part 44, the first connecting part 44 is provided with a third external thread 441, and the inner wall of the limiting component 5 has an internal thread that matches the third external thread 441. At least one of the outlet ends of the limiting component 5 has an inner diameter smaller than the outer diameter of the replacement device 20 but 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 products 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 removed, the replacement device 20 can be inserted into or removed from the opening at 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 in place by the limiting component 5, fixing the replacement device 20 within the cavity 47 of the container body 4. The replacement device 20 will not protrude from the opening end of the container body 4, allowing the paste or solid daily chemical products 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.

[0044] Preferably, the outer diameter of the limiting component 5 is the same as the outer diameter of the container body 4, forming a cylindrical shape with equal diameter after installation, resulting in a simple and aesthetically pleasing overall appearance. Furthermore, the limiting component 5 is cylindrical, and the end of the limiting component 5 is symmetrically formed with a slope 51, so that the shape of the port is a racetrack shape composed of two straight edges and two arc segments, which is consistent with the shape of the replacement device 20, thereby locking the end face of the replacement device 20.

[0045] See also Figure 2 , Figure 3a , Figure 5a , Figure 8 and Figure 10 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 part 45. The outer wall of the second connecting part 45 is provided with a plurality of arc-shaped protrusions 451 distributed circumferentially. The inner wall of the control unit 1 is provided with matching annular grooves 121 at corresponding positions. After the arc-shaped protrusions 451 and the annular grooves 121 are matched and engaged, they form a rotatable connection in the circumferential direction. Furthermore, the inner wall of the control unit 1 is also provided with a plurality of Z-shaped grooves 122 distributed circumferentially. The Z-shaped grooves 122 communicate with the annular grooves 121 and are open grooves. The arc-shaped protrusions 451 are installed into the annular grooves 121 along the Z-shaped grooves 122. The number of arc-shaped protrusions 451 and Z-shaped grooves 122 are the same, and their distribution positions are corresponding. During operation, by rotating the control unit 1 clockwise or counterclockwise, the lifting assembly 123 is controlled to extend or retract axially. Preferably, the outer diameter of the second connecting part 45 is slightly smaller than the outer diameter of the container body 4, and the outer diameter of the control part 1 is the same as the outer diameter of the container body 4. After installation, a cylindrical shape with equal diameter is formed.

[0046] See Figure 2 The lifting assembly 123 includes a screw 11, an internal threaded sleeve 2, and an external threaded sleeve 3. In the first embodiment, Figure 9a and Figure 3c As shown, the screw 11 and the control unit 1 are separate structures. The bottom surface of the screw 11 has a slot 14, the end of the screw 11 has an anti-detachment head 112, the bottom of the screw 11 has a plug-in portion 113, and the main body of the screw 11 has a first external thread 111. Figure 7a and Figure 7b As shown, the internal threaded sleeve 2 has a larger diameter main body 28 and a smaller diameter bottom 27. A first stop 26 is formed at the connection between the bottom 27 and the main body 28. The inner wall of the bottom 27 has a first internal thread 25 that matches the first external thread 111. The first internal thread 25 can be multiple segments of thread broken on the same turn, such as... Figure 7b As shown, the inner wall of the main body 28 is not provided with internal threads; the diameter of the anti-detachment head 112 is larger than the inner diameter of the bottom 27, so that the anti-detachment head 112 can be limited to the first stop position 26; after the screw 11 enters the internal thread sleeve 2, its insertion part 113 is inserted into the slot 14. When the control part 1 is rotated, the screw 11 rotates, causing the internal thread sleeve 2 to move axially.

[0047] See Figure 7a and Figure 7bThe internal threaded sleeve 2 includes a main body 28, a threaded snap fastener 21, and a first spring 23. A second through hole 22 is symmetrically arranged at the top of the main body 28. The threaded snap fastener 21 includes a second external thread 211, a snap fastener 212, and a limiting protrusion 213. The size of the snap fastener 212 is larger than the size of the second through hole 22. The second external thread 211 passes through the second through hole 22 and is located outside the main body 28. The snap fastener 212 is snapped into the main body 28. Both ends of the first spring 23 are sleeved on the limiting protrusion 213. The inner surface of the external threaded sleeve 3 is provided with a second internal thread 32 that matches the second external thread 211. The first spring 23... In the free state, the inner diameter of the mounting opening of the external thread sleeve 3 is smaller than the outer diameter of the second external thread 211. After the second external thread 211 is compressed by the elasticity of the first spring 23, the external thread sleeve 3 is fitted onto the outside of the internal thread sleeve 2. When the internal thread sleeve 2 rotates with the screw 11, the second external thread 211 and the second internal thread 32 engage in a spiral motion, thereby causing the external thread sleeve 3 to move axially. The bottom end of the second internal thread 32 is provided with a second stop 33. When the second external thread 211 rotates to the bottom, the external thread sleeve 3 is locked and stops axial movement, and the second external thread 211 is locked in the root groove of the second internal thread 32.

[0048] See Figure 4 , Figure 5b and Figure 6 The container body 4 and the guide tube 41 are separate structures. A first protruding rib 31 is provided axially on the outer surface of the external threaded sleeve 3. A first through hole 461 is provided in the middle of the bottom surface 46 of the container body 4. The guide tube 41 is installed inside the first through hole 461. A radial flange 413 is provided at the top of the guide tube 41. The diameter of the radial flange 413 is larger than the diameter of the first through hole 461, so that the guide tube 41, after passing through the first through hole 461, is stuck at the bottom of the container body 4. The guide tube 41 is provided with a guide groove 411 that matches the first protruding rib 31. The guide groove 411 can be as follows: Figure 4 The radially penetrating open slot shown can also be Figure 5b The outer closed groove shown has a guide tube 41 sleeved on the outer threaded sleeve 3, which serves to stabilize, guide, and protect the lifting assembly 123. During operation, it prevents the paste or solid daily chemical products inside the box 201 from shaking or tilting, allowing the paste or solid daily chemical products to move smoothly. The top end of the outer threaded sleeve 3 passes through the first through hole 461 and extends into the cavity 47 of the container body 4. A lifting platform 34 is provided at the top end of the outer threaded sleeve 3. The lifting platform 34 is connected to the bottom 202 of the replacement device 20. The first protrusion 31 is inserted into the guide groove 411 and can move axially along the guide groove 411 through the first through hole 461 into the cavity 47 of the container body 4. This further prevents the paste or solid daily chemical products inside the box 201 from shaking or tilting, allowing the paste or solid daily chemical products to move smoothly.

[0049] In this embodiment, the lifting platform 34 and the external threaded sleeve 3 are separate structures, with the external threaded sleeve 3 being fitted into the end of the external threaded sleeve 3. The entire packaging container can be made of metal.

[0050] In this embodiment, when the lifting assembly 123 is in Figure 3a In the contracted state shown, when the control unit 1 is rotated, the screw 11 and the internal threaded sleeve 2 are driven to rotate. The second external thread 211 and the second internal thread 32 engage to cause the external threaded sleeve 3 to rise along the guide groove 411. The first external thread 111 and the first internal thread 25 engage to cause the internal threaded sleeve 2 to rise along the screw 11. When the second external thread 211 reaches the bottom end of the external threaded sleeve 3, it is restricted by the second stop 33. Figure 3b As shown. When the screw 11 rotates to the bottom end of the internal threaded sleeve 2, the anti-detachment head 112 is limited to the first stop position 26. After the internal threaded sleeve 2 and the external threaded sleeve 3 have both rotated to the top, this position is the highest position that the lifting assembly 123 can rise to, as shown. Figure 3c As shown. Therefore, by using three stackable lifting components, the height is increased by about twice that of the existing single-screw lifting structure while occupying the same height space. Conversely, when the same lifting height is required, the height of the lifting component 123 in the retracted state can be halved, which greatly reduces the volume of the packaging container 10, making the entire packaging container 10 compact and easy to carry and use.

[0051] See Figure 12a In the second embodiment, the lifting assembly 123 includes a screw 11, an internal threaded sleeve 2, and an external threaded sleeve 3. The screw 11 is integrally connected to the bottom surface of the control unit 1, and the screw 11 has a first external thread 111. The inner wall of the internal threaded sleeve 2 is provided with a first internal thread 25 that matches the first external thread 111. When the control unit 1 is rotated, the screw 11 rotates, causing the internal threaded sleeve 2 to move axially. Figure 14 As shown, the top end of the internal threaded sleeve 2 is provided with a slot 24, the inner diameter of the mounting opening of the external threaded sleeve 3 is smaller than the outer diameter of the second external thread 211, and the outer surface of the internal threaded sleeve 2 near the top end is provided with a second external thread 211 that is interrupted by the slot 24. The inner surface of the external threaded sleeve 3 is provided with a second internal thread 32 that matches the second external thread 211. The external threaded sleeve 3 is sleeved on the outside of the internal threaded sleeve 2 by utilizing the elasticity of the slot 24. When the internal threaded sleeve 2 rotates with the screw 11, the second external thread 211 and the second internal thread 32 engage, thereby causing the external threaded sleeve 3 to move axially. The bottom end of the second internal thread 32 is provided with a second stop 33. When the second external thread 211 rotates to the bottom, the external threaded sleeve 3 is stuck and stops axial movement.

[0052] In this embodiment, such as Figure 13As shown, the top of the lifting platform 34 and the external threaded sleeve 3 are integrally formed. The overall material of the packaging container can be made of plastic, and the lifting platform 34, the external threaded sleeve 3, the controller 1 and the screw 11, the container body 4 and the guide tube 41 can all be integrally injection molded.

[0053] Similar to the first embodiment, when the lifting assembly 123 is in Figure 12a In the contracted state shown, when the control unit 1 is rotated, the screw 11 and the internal threaded sleeve 2 are driven to rotate. The second external thread 211 and the second internal thread 32 engage, causing the first protrusion 31 of the external threaded sleeve 3 to rise along the guide groove 411. The first external thread 111 and the first internal thread 25 engage, thereby causing the internal threaded sleeve 2 to rise along the screw 11. When the second external thread 211 reaches the bottom end of the external threaded sleeve 3, it is restricted by the second stop 33. Figure 12b As shown. When the screw 11 rotates to the bottom end of the internal threaded sleeve 2, the first external thread 111 is limited to the first stop position 26. After the internal threaded sleeve 2 and the external threaded sleeve 3 have both rotated to the top, this position is the highest position that the lifting assembly 123 can rise to, as shown. Figure 12c As shown. Therefore, by using three stackable lifting components, the height is increased by about twice that of the existing single-screw lifting structure while occupying the same height space. Conversely, when the same lifting height is required, the height of the lifting component 123 in the retracted state can be halved, which greatly reduces the volume of the packaging container 10, making the entire packaging container 10 compact and easy to carry and use.

[0054] In other embodiments, those skilled in the art can adjust the number of retractable threaded sleeves constituting the lifting assembly 123 as needed based on the above implementation scheme. A similar mating structure can be used to set more threaded sleeves for stacking assembly to reduce the space occupied by the lifting assembly 123. This utility model does not impose any particular limitation on this.

[0055] Furthermore, see Figure 2 , Figure 3a and Figure 12a It also includes a second spring 7. The second spring 7 is sleeved on the outer periphery of the bottom of the screw 11. The top of the second spring 7 contacts the inner threaded sleeve 2. The second spring 7 is located inside the outer threaded sleeve 3. The function of the second spring 7 is to prevent the inner threaded sleeve 2 from locking when it descends to the bottom, so that it cannot rise during the second lifting and lowering.

[0056] Further, see Figure 9bThe control unit 1 includes an inner base 12 and an outer base 13. The inner wall of the inner base 12 is provided with an annular groove 121 and a Z-shaped groove 122, and the outer wall of the inner base 12 is provided with a second protruding ridge 124. The inner wall of the outer base 13 is provided with a first groove 131. The second protruding ridge 124 is fitted into the first groove 131 for assembly. Furthermore, the outer base 13 is provided with raised textures 132 to enhance friction and facilitate grip and operation without slipping.

[0057] See Figure 1 , Figure 2 and Figure 3a 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 is screwed to the control unit 1. The container lid 6, the container body 4, and the control unit 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 handling feel.

[0058] Please see Figure 2 and Figure 11 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 a recess in the middle of the box bottom 202 towards the open end 2011. The box body 201 has a cavity for placing paste or solid daily chemical products. The cross-sectional shape of the box body 201 is a racetrack shape composed of two straight sides and two arcs. Compared with a cylindrical box body, this shape will not rotate circumferentially within the container body 4, thus affecting the user experience. Correspondingly, as... Figure 5a As shown, the inner wall of the container body 4 is provided with ribs 48, which contact the straight edge of the box body 201. Preferably, there are four ribs 48 symmetrically arranged inside the container body 4. The lifting component 123 controls the bottom of the box 202 to move axially, thereby controlling the paste or solid daily chemical product on the bottom of the box 202 to move axially. The paste or solid daily chemical product can be used by the consumer after it extends out of the second end 43 of the container body 4. 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, etc., to close the opening end 2011 of the replacement device 20 and protect the unused daily chemical product in the replacement device 20 from contamination; the sealing component is removed when in use. In this embodiment, the replacement device 20 is made of biodegradable material. Furthermore, the replacement device 20 is made of paper material, which is environmentally friendly, biodegradable, and recyclable.

[0059] Please see Figure 1 and Figure 2This embodiment also provides a daily chemical product, including the aforementioned packaging container 10 and a 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 lifting platform 34 provided at the top of the external threaded sleeve 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 lifting platform 34. Further, as Figure 13 As shown, the side surface of the lifting platform 34 is provided with barbs 341 to prevent the daily chemical products (paste or solid) inside the box 201 from shaking or tilting, so that the daily chemical products (paste or solid) can move smoothly. When the rotation control unit 1 moves the lifting platform 34 along the axial direction, it moves the paste or solid daily chemical products relative to the box 201, so that the paste or solid daily chemical products are exposed at the first end 42 of the container body 4 for consumer use, or are returned to the replacement device 20 for storage after use.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.
