Detailed Implementation

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] This embodiment discloses a single-hand cosmetic packaging method, referring to... Figures 1-13 As shown, the device includes a housing 1, and inside the housing 1 are installed components such as a lifting block 1 2, a lifting block 2 5, a gear 4, and an inner bottle 3. Both lifting blocks 1 2 and lifting blocks 2 5 are slidably installed inside the housing 1 in the vertical direction. The gear 4 meshes and drives between lifting blocks 1 2 and lifting blocks 2 5, enabling them to slide and move in opposite directions. By sliding lifting blocks 2 5, lifting blocks 1 2 and the inner bottle 3 can be driven, allowing part of the inner bottle 3 to extend outside the housing 1, enabling one-handed operation.

[0042] Reference 1~ Figure 3 As shown, the shell 1 mainly consists of four parts: an outer shell 130, a cover 120, and two half-shells 110. The two half-shells 110 overlap each other to form an open cavity at the top. The interlocking structure of the opposite parts of the two half-shells 110 allows for alignment of their installation structure. The outer shell 130 is fitted onto the outside of the two half-shells 110, forming a fitted structure around the two half-shells 110 and reinforcing their fixation. The cover 120 is installed on the upper end of the two half-shells 110, and an opening 121 is provided at the middle of the upper end of the cover 120. This opening 121 allows the upper part of the inner bottle 3 to extend and retract.

[0043] Lifting block 1 (2) and lifting block 2 (5) are both slidably installed inside the housing 1 in the vertical direction. In order to guide the two lifting blocks, sliding groove 1 (111) and sliding groove 2 (112) are integrally formed on the inner side of the half-shell 110. Sliding groove 1 (111) and sliding groove 2 (112) are parallel to each other in the vertical direction.

[0044] A guide slide part 201 is integrally formed on the outer side of the lifting block 2. The guide slide part 201 can be embedded into the slide groove 111 and can guide the lifting block 2 up and down. A guide slide part 501 is integrally formed on the outer side of the lifting block 2. The guide slide part 501 can be embedded into the slide groove 112 and can guide the lifting block 2 5 up and down.

[0045] A handle 503 is fixedly connected to the lifting block 2 5. The handle 503 can extend from the side wall of the housing 1 to form a handle structure for one-handed operation. A clearance groove 114 is provided on the outer side of the housing 1. The clearance groove 114 is arranged in the vertical direction and is consistent with the sliding path of the handle 503. Specifically, half of the sliding groove 111 is pre-formed at the position where the two half-shells 110 overlap each other. After the two half-shells 110 overlap each other, the complete sliding groove 111 is formed. In addition, a clearance groove 2 131 is also provided at the corresponding position of the outer shell 130, so that the handle 503 can extend outside the outer shell 130 for convenient operation of the handle 503.

[0046] Gear 4 is rotatably connected inside housing 1 and located between lifting block 1 2 and lifting block 2 5. It can form a meshing transmission between lifting block 1 2 and lifting block 2 5, and make the sliding directions of lifting block 1 2 and lifting block 2 5 opposite.

[0047] Specifically, refer to Figure 3 As shown, a rotating shaft 115 is integrally formed in the inner wall of the half shell 110. The gear 4 is rotatably mounted on the rotating shaft 115, which enables a smooth rotational connection structure.

[0048] Reference Figure 7 , Figure 8 As shown, lifting block 2 has a rack portion 202, and lifting block 5 has a rack portion 502. The rack portion 202 and rack portion 502 are arranged opposite to each other, and gear 4 is located between the rack portion 202 and rack portion 502. Both rack portion 202 and rack portion 502 mesh with gear 4 for transmission. Through gear 4, lifting block 2 and lifting block 5 can be mutually transmitted, and the two can form opposite movement actions.

[0049] Reference Figures 4-6 As shown, during the lifting adjustment process, the lifting block 2 5 has an upward movement state (such as...). Figure 6 ) and downshifted states (such as Figure 4 , Figure 5 In the downward state, the second lifting block 5 slides downward, and the rack part 502 of the second lifting block 5 meshes with the gear 4 for transmission. Then, the gear 4 drives the rack part 202 of the first lifting block 2 to slide upward. The inner bottle 3 will rise synchronously with the first lifting block 2, so that part of the inner bottle 3 extends out of the shell 1 from the opening 121, and the liquid in the inner bottle 3 can be used.

[0050] Conversely, when the lifting block 2 5 is in the upward state, the lifting block 2 5 slides upward, the rack part 2 502 of the lifting block 2 5 meshes with the gear 4, and then the gear 4 drives the rack part 202 of the lifting block 1 2 to slide downward. The inner bottle 3 will follow the lifting block 1 2 and descend synchronously, so that part of the inner bottle 3 is retracted into the shell 1 from the opening 121, which can realize the storage of the inner bottle 3.

[0051] In this embodiment, the opening 121 at the upper end of the cover 120 can be closed by the inner cover 6; when the inner bottle 3 needs to be used, the inner cover 6 can open the opening 121 to facilitate the extension of the inner bottle 3.

[0052] Specifically, the inner wall of the half-shell 110 of the housing 1 is also provided with a sliding groove 3 113, which is connected to the upper end of the sliding groove 2 112 and is inclined. The inner cover 6 has a connecting part 601, which is rotatably connected to the upper end of the lifting block 2 5 via a rotating shaft. The inner cover 6 can be deflected to adapt to the opening and closing action. A guide sliding part 3 602 is fixedly connected to the outside of the inner cover 6. The guide sliding part 3 602 can slide along the sliding groove 3 113 and the sliding groove 2 112, thereby adapting to the movement of the sliding groove to generate deflection activity.

[0053] When the lifting block 2 5 is in the upward state, the lifting block 2 5 slides upward, and the guide part 3 602 of the inner cover 6 slides upward from the slide groove 2 112 to the slide groove 3 113, so that the inner cover 6 can deflect along the slide groove 3 113, and the inner cover 6 can deflect from a roughly vertical state to a roughly horizontal state, thereby allowing the inner cover 6 to close the opening 121; at the same time, the inner bottle 3 can retract from the opening 121 into the shell 1 to realize the storage of the inner bottle 3.

[0054] When the lifting block 2 5 is in the downward state, the lifting block 2 5 slides down, and the guide part 3 602 of the inner cover 6 slides down from the slide groove 3 113 to the slide groove 2 112, so that the inner cover 6 can be deflected. The inner cover 6 can be deflected from a roughly horizontal state to a roughly vertical state, so that the inner cover 6 can slide down and separate from the opening 121, and the opening 121 can be opened; at the same time, the upper part of the inner bottle 3 can extend upward from the opening 121, which can be used by the user.

[0055] During use, the user can hold the packaging cavity in this embodiment with one hand and push the handle 503 of the lifting block 2 5 upward with the thumb to open the inner cover 6 and raise the inner bottle 3, making it convenient for the user to apply the product. When storing, the user can push the handle 503 of the lifting block 2 5 downward with the thumb to close the inner cover 6 and retract the inner bottle 3 into the shell, making it convenient for the user to store.

[0056] Furthermore, in this embodiment, the inner bottle 3 can adopt the structure of a roll-on / roll-off bottle. Specifically, refer to... Figures 9-11As shown, the inner bottle 3 has a bottle opening 302 at its upper end. A roller-type bottle cap 310 is installed at the bottle opening 302 of the inner bottle 3, which forms a roller structure at the bottle opening 302. Specifically, a roller 311 is installed inside the roller cap 310. By rolling the roller 311, the cream in the inner bottle 3 can be dispensed. The specific structure of the roller cap 310 and the roller 311 is conventional technology in the art and will not be described in detail here.

[0057] In this embodiment, the lifting block 2 is fixedly connected to a mounting base 203 and a limiting base 204. The mounting base 203 is located at the upper end of the lifting block 2, and the limiting base 204 is located at the lower end of the lifting block 2. The mounting base 203 and the limiting base 204 are arranged vertically opposite each other. The inner bottle 3 is installed on the mounting base 203. Specifically, the mounting base 203 has a roughly clamp-like structure, which can engage and limit the inner bottle 3 with the locking part 301 on the outside of the inner bottle 3, thereby enabling the installation of the inner bottle 3.

[0058] In addition, the single-hand cosmetic packaging in this embodiment also includes a screw 7 and a linkage sleeve 8. The linkage sleeve 8 is installed between the lower end of the inner bottle 3 and the limiting seat 204, and the lower end of the linkage sleeve 8 is rotatably supported by the limiting seat 204. An annular protrusion 205 is integrally connected to the upper side of the limiting seat 204. The lower end of the linkage sleeve 8 and the annular protrusion 205 fit together, which can realize the rotational limitation of the linkage sleeve 8; the upper end of the linkage sleeve 8 is blocked by the lower end of the inner bottle 3.

[0059] A guide hole 303 is provided at the lower end of the inner bottle 3. The screw 7 passes through the guide hole 303 and can slide up and down relative to the guide hole 303 while restricting axial rotation. Specifically, a flat part 702 is formed on one side of the screw 7, and the shape of the guide hole 303 is also adapted to the screw to restrict the relative rotation between the two.

[0060] A piston block 703 is fixedly connected to the upper end of the screw 7. The shape of the piston block 703 is adapted to the inner circumference of the inner bottle 3. A piston seal 704 is installed on the outer circumference of the piston block 703, and the piston seal 704 is sealed to the inner wall of the inner bottle 3. During the lifting and lowering process, the screw 7 can form a piston movement with the inner cavity of the inner bottle 3, which can push the liquid in the inner bottle 3 to be output.

[0061] The lower end of the screw 7 extends into the linkage sleeve 8, and an external thread 701 is provided on the outer circumference of the screw 7; an internal thread 801 is provided on the inner circumference of the linkage sleeve 8, and the internal thread 801 and the external thread 701 are threadedly matched with each other. The screw 7 can form a threaded connection with the linkage sleeve 8.

[0062] During use, by rotating and adjusting the linkage sleeve 8, the linkage sleeve 8 and the screw 7 will be linked by a thread, and the screw 7 will move up and down, so that the upper end of the screw 7 can achieve piston movement in the inner bottle 3, which can push the liquid in the inner bottle 3 to move upward.

[0063] Furthermore, referring to Figures 11-13 As shown, a linkage structure is formed on the outer periphery of the linkage sleeve 8. A linkage block 504 is fixedly connected to the lower side of the lifting block 2 5. The linkage block 504 can be embedded in the linkage structure and can be linked with the linkage structure. During the upward and downward sliding of the lifting block 2 5, the linkage block 504 and the linkage structure are linked with each other, which can drive the linkage sleeve 8 to rotate, thereby driving the screw 7 and the inner bottle 3 to achieve piston movement, which can push the piston block 703 to push the liquid upward.

[0064] Specifically, the linkage structure includes several linkage protrusions 810 and 820 integrally formed on the outer periphery of the linkage sleeve 8. Generally, there are four linkage protrusions 810 and 820, arranged in a circular array. Linkage protrusions 810 are located on the lower side of the linkage sleeve 8 and are distributed in a circular array on the outer periphery of the linkage sleeve 8. The number of linkage protrusions 820 is the same as that of linkage protrusions 810, located on the upper side of the linkage sleeve 8, and staggered from linkage protrusions 810.

[0065] Along the circumferential direction, the linkage protrusion 810 has a first side 811 and a second side 812, and a linkage groove 814 is formed between adjacent linkage protrusions 810.

[0066] An inclined section 813 is formed on the upper half of the second side 812 of the linkage protrusion 810. That is, at the position of the inclined section 813, the width of the linkage groove 814 gradually narrows downward until it is in the same position as the lower half of the linkage groove 814. The lower half of the linkage groove 814 will have the same width.

[0067] The second linkage protrusion 820 is located above the first linkage protrusion 810, and specifically above the first side 811 of the first linkage protrusion 810. A linkage inclined surface 821 is formed on the lower side of the second linkage protrusion 820. The linkage inclined surface 821 is directly opposite to the upper side of the first side 811 of the first linkage protrusion 810, and the inclination direction of the linkage inclined surface 821 is opposite to that of the inclined segment 813.

[0068] Furthermore, a notch is formed between the upper end of the linkage inclined surface 821 and the linkage protrusion 810, allowing the linkage block 504 to pass through. The linkage block 504 can move up and down synchronously with the lifting block 5. During the lifting and sliding process, the linkage block 504 can apply a rotational push to the linkage protrusion 810 and the linkage protrusion 820, thereby forming a threaded linkage between the linkage sleeve 8 and the screw 7.

[0069] Specifically, the linkage block 504 is located in the linkage groove 814 between the two linkage protrusions 810. During the downward movement of the lifting block 5 and the linkage block 504, the linkage block 504 will move downward in the linkage groove 814. The linkage block 504 will press against the inclined section 813 of the linkage protrusion 810, applying a circumferential rotational force to the inclined section 813, so that the linkage sleeve 8 can rotate slightly. Through the threaded linkage between the linkage sleeve 8 and the screw 7, the screw 7 can be driven to rise slightly. Until the linkage block 504 moves to the lower half of the linkage groove 814, the linkage sleeve 8 will no longer rotate.

[0070] Then, as the lifting block 2 5 and the linkage block 504 move downward, the linkage block 504 will slide upward along the lower half of the linkage groove 814. During the sliding process, the linkage block 504 and the first side 811 of the linkage protrusion 1 810 approach each other until the upper side of the linkage block 504 abuts against the linkage inclined surface 821 of the linkage protrusion 2 820. Under the inclined guiding action of the linkage inclined surface 821, the linkage block 504 will generate a circumferential rotational component force on the linkage protrusion 2 820, which can push the linkage sleeve 8 to deflect slightly. During the slight deflection of the linkage sleeve 8, the linkage block 504 will pass through the gap 822 between the linkage protrusion 1 810 and the linkage protrusion 2 820 and enter the upper position of another linkage groove 814.

[0071] Then, lifting block 2 5 and linkage block 504 move downwards, repeating the above linkage process, which can realize the rotational push of linkage sleeve 8. The upper end of screw 7 can form an upward piston push inside inner bottle 3, which facilitates the lifting of the liquid level in inner bottle 3. During each complete lifting action of lifting block 2 5, the piston at the bottom of inner bottle 3 will rise slightly, and the liquid level in inner bottle 3 will rise slightly, ensuring that the inner side of ball bearing 311 can effectively contact the liquid, which is convenient for users.

[0072] Furthermore, to improve the smoothness of linkage between linkage block 504 and linkage protrusion 1 810 and linkage protrusion 2 820, an upper guide slope 505 is formed on the upper side of linkage block 504, a lower guide slope 506 is formed on the lower side of linkage block 504, and rounded corners are made at the edge transition.

[0073] The upper guide slope 505 and the linkage slope 821 are inclined in the same direction. When the linkage block 504 moves upward and presses against the linkage slope 821, a smooth slope pressing and guiding effect can be formed to ensure the smoothness of the linkage action. In addition, a lower guide slope 506 is formed on the lower side of the linkage block 504. The lower guide slope 506 and the upper guide slope 505 are inclined in opposite directions. When the linkage block 504 moves downward, the lower guide slope 506 can press against the upper end of the linkage protrusion 810, so that the linkage block 504 can pass smoothly through the notch 822 and form a smooth linkage action at the pressing point, which can improve the smoothness of the overall cooperation between the linkage block 504 and the linkage structure.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
