Description

Technical Field

[0001] This application relates to the technical field of cosmetic boxes, and in particular to a worm gear airtight powder box. Background Technology

[0002] The main function of a cosmetic box is to hold cosmetics. With the continuous development of science and technology, the types of cosmetics are increasing day by day, including volatile skin care products such as eye cream, face cream, essence water, lotion and powder. In order to prevent cosmetics from evaporating quickly, the requirements for the airtightness of cosmetic boxes are also getting higher and higher.

[0003] Cosmetics in cosmetic boxes are usually sealed with a layer of aluminum foil before opening. Before using the cosmetics, the aluminum foil needs to be torn off. However, tearing off the aluminum foil will cause gaps when the cosmetic box is closed, which will reduce the sealing of the cosmetic box. This problem urgently needs to be solved. Summary of the Invention

[0004] To improve the sealing performance of cosmetic boxes, this application provides a worm gear airtight powder box.

[0005] This application provides a worm gear airtight powder box, which adopts the following technical solution: A worm gear airtight powder box, comprising: The main body includes a box and a lid. The box contains cosmetics, and the lid is flipped and connected to the side of the box for opening and closing the box. The inner periphery of the box is provided with a receiving cavity. A powder puff tray assembly is disposed inside the box body. The powder puff tray assembly includes a tray body and a base. The base is coaxially rotatably connected to the receiving cavity. The tray body is flipped and connected to the side of the base. When the tray body is flipped to a state parallel to the box body, the bottom of the tray body covers the cosmetics inside the box body, and the powder puff is placed on the tray body. The linkage component includes a worm gear and a worm wheel that cooperate with each other. The worm gear is fixedly connected to the cover at a position where it flips and connects with the box. The worm wheel is coaxially rotatably connected to the receiving cavity and engages with the base. When the cover flips open from the box, the worm wheel drives the base to move vertically upward. When the cover flips closed from the box, the worm wheel drives the base to move vertically downward.

[0006] By adopting the above technical solution, the box contains cosmetics, and the tray holds the powder puff. When a new powder box needs to be used, the sealing aluminum foil needs to be torn off. At this time, there is a gap between the tray and the opening of the box where the cosmetics are held. When the lid is flipped down to close the box, the worm gear rotates with the flip of the lid. The rotating worm gear drives the worm wheel to rotate, and the worm wheel drives the base to move vertically downward. The vertically downward moving base simultaneously drives the tray, which has flipped down to be parallel to the box, to move vertically downward, thus sealing the gap created by tearing off the aluminum foil, thereby improving the sealing of the cosmetic box. When the user needs to use the cosmetics, the user flips the lid up to open it. The flip of the lid drives the worm gear to rotate in the opposite direction, and the reverse-rotating worm gear drives the worm wheel to rotate in the opposite direction. The worm wheel drives the base to move vertically upward, and the vertically upward moving base simultaneously drives the tray to move vertically upward. The user can then take out the powder puff from the tray, and then flip the tray up to use the powder puff to apply the cosmetics. The operation is simple and convenient.

[0007] Preferably, the worm gear portion is provided with a snap-fit ​​block, and the base is provided with a snap-fit ​​groove for the snap-fit ​​block to move. The bottom of the snap-fit ​​block is inclined at the position where it is inserted into the snap-fit ​​groove, and the bottom of the snap-fit ​​block is in contact with the bottom of the snap-fit ​​groove.

[0008] By adopting the above technical solution, when the lid is flipped down to close the box, the lid drives the worm gear to rotate, and the rotating worm gear drives the worm wheel to rotate horizontally. Since the bottom of the snap-fit ​​block is inclined when it is inserted into the snap-fit ​​groove, and the bottom of the snap-fit ​​block is in contact with the bottom of the snap-fit ​​groove, the horizontally rotating worm wheel pushes the base to move vertically downward, and simultaneously drives the disc to move vertically downward, thereby eliminating the gap between the disc and the opening of the box, thus improving the sealing of the cosmetic box.

[0009] Preferably, a sealing ring is provided at the opening of the box body, and when the disc body is flipped to a state parallel to the box body, the sealing ring surrounds and abuts against the bottom of the disc body.

[0010] By adopting the above technical solution, when cosmetics are not needed, the tray is flipped to a state parallel to the box. At this time, the sealing ring surrounds and abuts against the bottom of the tray to enhance the sealing of the box for storing cosmetics.

[0011] Preferably, the sealing ring is made of soft sealant, and the upper end of the sealing ring is inclined toward the outside of the box body.

[0012] By adopting the above technical solution, when the disc is flipped to a state parallel to the box, the disc covers the opening of the box containing cosmetics. As the disc moves vertically downward, the space in the box containing cosmetics gradually decreases, which increases the pressure in the space containing cosmetics. At this time, the pressure in the space containing cosmetics is greater than the external pressure, so as to push the upper end of the sealing ring to press against the bottom of the disc, thereby further improving the sealing effect.

[0013] Preferably, a pad is provided around the inner side of the opening of the box, the pad extends toward the inner side of the box, and the pad is parallel to the bottom of the box.

[0014] By adopting the above technical solution, the pad has a sealing effect on the opening of the space where the cosmetics are contained in the box, which helps to prevent the cosmetics from spilling out during use. In addition, the pad increases the contact area between the tray and the opening of the box, which helps to improve the sealing effect.

[0015] Preferably, a limiting groove is formed around the bottom of the worm gear, and a limiting post is provided inside the housing cavity, with the limiting post inserted into the limiting groove.

[0016] By adopting the above technical solution, the limiting post is inserted into the limiting groove to limit and guide the rotation of the worm gear, which helps to improve the stability of the worm gear during rotation, thereby improving the stability of the cosmetic box during use.

[0017] Preferably, the opening of the box body extends outward to form a protrusion.

[0018] By adopting the above technical solution, this setting limits the base, making it difficult for the base that needs to move up and down to detach from the accommodating cavity.

[0019] Preferably, the plate body is provided with a handle on its side.

[0020] By adopting the above technical solution, the handle design facilitates the user's operation of flipping the plate.

[0021] Preferably, there are several sets of the engaging blocks and engaging slots, and the several sets of engaging blocks and engaging slots are evenly spaced along the periphery of the worm gear portion.

[0022] By adopting the above technical solution, several sets of matching snap-fit ​​blocks and snap-fit ​​grooves are evenly spaced along the periphery of the worm gear, which helps to improve the stability of the base and the disc when moving vertically up and down, and thus helps to improve the sealing of the cosmetic box.

[0023] Preferably, the limiting post has a weight-reducing hole in the vertical direction.

[0024] By adopting the above technical solution, this design helps to reduce the weight of the cosmetic box, thereby improving its portability.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a main body, a powder puff tray assembly, and a linkage assembly, the main body includes a flip-connected box and a lid; the powder puff tray assembly includes a flip-connected base and a tray; and the linkage assembly includes a mating worm gear and a worm wheel. When a new powder box needs to be used, the sealing aluminum foil needs to be torn off. At this time, there is a gap between the tray and the opening of the box for holding cosmetics. When the lid is flipped down to close the box, the worm gear rotates along with the flip of the lid. The rotating worm gear drives the worm wheel to rotate, and the worm wheel drives the base to move vertically downward. The vertically downward movement of the base synchronously drives the flip. The tray, parallel to the box, moves vertically downwards to seal the gap created by tearing off the aluminum foil, thus improving the sealing of the cosmetic box. When the user needs to use the cosmetic, they flip the lid upwards to open it. The flipping of the lid causes the worm gear to rotate in the opposite direction, which in turn causes the worm wheel to rotate in the opposite direction. The worm wheel causes the base to move vertically upwards, and the vertically moving base simultaneously causes the tray to move vertically upwards. The user can then remove the powder puff from the tray, flip the tray upwards, and use the powder puff to apply the cosmetic. The operation is simple and convenient.

[0026] 2. By setting a snap-fit ​​block and a snap-fit ​​groove, when the cover is flipped down to close the box, the cover drives the worm gear to rotate, and the rotating worm gear drives the worm wheel to rotate horizontally. Since the bottom of the snap-fit ​​block is inclined when it is inserted into the snap-fit ​​groove, and the bottom of the snap-fit ​​block is in contact with the bottom of the snap-fit ​​groove, the horizontally rotating worm wheel pushes the base to move vertically downward, and simultaneously drives the disc to move vertically downward, thereby eliminating the gap between the disc and the opening of the box, thus improving the sealing of the cosmetic box.

[0027] 3. By setting a sealing ring, when the disc is flipped to a state parallel to the box, the disc covers the opening of the box containing cosmetics. As the disc moves vertically downward, the space in the box containing cosmetics gradually decreases, which increases the pressure in the space containing cosmetics. At this time, the pressure in the space containing cosmetics is greater than the external pressure, so as to push the upper end of the sealing ring to press against the bottom of the disc, thereby further improving the sealing effect.

[0036] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0037] In existing cosmetic boxes, cosmetics are usually sealed with a layer of aluminum foil before opening. Before using the cosmetics, the aluminum foil needs to be torn off. However, tearing off the aluminum foil will create gaps when the cosmetic box is closed, thus reducing the sealing performance of the cosmetic box.

[0038] To address the aforementioned problems, this application discloses a worm gear airtight powder box, referring to... Figure 1 and Figure 2 The cosmetic box includes a main body 1, a powder puff tray assembly 3, and a linkage assembly 4. The main body 1 is used to hold cosmetics, the powder puff tray, and the linkage assembly 4. The powder puff tray assembly 3 is used to hold the powder puff. The linkage assembly 4 is used to link the main body 1 and the powder puff tray assembly 3 to eliminate gaps caused by tearing the aluminum foil, thereby improving the sealing of the cosmetic box.

[0039] Reference Figure 1 and Figure 2 The main body 1 includes a box body 11 and a lid 12. In this embodiment, both the box body 11 and the lid 12 have circular cross-sections. The lid 12 is flipped and connected to the side of the box body 11 for opening and closing the box body 11. (Refer to...) Figure 3 The cosmetics are placed in the middle of the box body 11. The inner periphery of the box body 11 is provided with a receiving cavity 2 for receiving the powder puff tray assembly 3 and the linkage assembly 4.

[0040] Reference Figure 3 and Figure 4 The powder puff tray assembly 3 is located inside the box body 11. Specifically, the powder puff tray assembly 3 includes a tray body 31 and a base 32. The base 32 is coaxially rotatably connected to the receiving cavity 2. The tray body 31 is flipped and connected to the side of the base 32. When the tray body 31 is flipped to a state parallel to the box body 11, the bottom of the tray body 31 covers the cosmetics inside the box body 11, and the powder puff is placed on the tray body 31. When the user needs to use cosmetics, the user takes the powder puff out of the tray body 31 and flips the tray body 31 upward so that the user can use the powder puff to apply cosmetics for makeup operations.

[0041] Reference Figure 5 and Figure 6 The outer side of the opening of the box 11 extends outward to form a protrusion 13 to prevent the base 32 from detaching from the receiving cavity 2. (Refer to...) Figure 4 To facilitate the user's operation of flipping the disc body 31, a handle 14 is provided on the side of the disc body 31. In this embodiment, the handle 14 is located on the opposite side of the connection position between the disc body 31 and the base 32.

[0042] Reference Figure 3 and Figure 6 A pad 8 is arranged around the inner side of the opening of the box body 11. The pad 8 extends in a ring towards the inner side of the box body 11 and is parallel to the bottom of the box body 11, so that the space in the box body 11 that contains cosmetics has a sealing effect, making it difficult for cosmetics to spill out during use. The pad 8 also increases the contact area between the tray body 31 and the opening of the box body 11, thereby improving the sealing effect.

[0043] Reference Figure 6 and Figure 7 The linkage component 4 includes a worm gear part 41 and a worm wheel part 42 that cooperate with each other. The worm gear part 41 is horizontally fixedly connected to the cover 12 at the position where it is flipped and connected to the box 11. The worm wheel part 42 is coaxially rotatably connected to the accommodating cavity 2 and is engaged with the base 32. When the lid 12 is flipped open from the box 11, the lid 12 drives the worm gear 41 to rotate. The worm gear 41 drives the worm wheel 42, which cooperates with it, to rotate horizontally within the accommodating cavity 2. The worm wheel 42 then drives the base 32 to move vertically upward, and at the same time, the base 32 drives the disc 31 to move vertically upward. When the lid 12 is flipped closed on the box 11, the lid 12 drives the worm gear 41 to rotate in the opposite direction. The worm gear 41 drives the worm wheel 42, which cooperates with it, to rotate in the opposite direction. The worm wheel 42 then drives the base 32 and the disc 31 to move vertically downward. The disc 31 moves vertically downward to eliminate the gaps caused by the removal of the aluminum foil, thereby sealing the closed cosmetic box.

[0044] Specifically, the worm gear part 42 is provided with a locking block 5, and the base 32 has a locking groove 6 for the locking block 5 to move in. The bottom of the locking block 5 is inclined when it is inserted into the locking groove 6, and the bottom of the locking block 5 is in contact with the bottom of the locking groove 6. Through the step of flipping the cover 12 downward to close the box 11, the locking block 5 moves in the horizontal direction. During the horizontal movement, the locking block 5 presses the base 32 downward by the inclined bottom, so that the base 32 and the disc 31 move vertically downward, thereby sealing the closed cosmetic box. It should be noted that there are several sets of matching locking blocks 5 and locking grooves 6. The sets of locking blocks 5 and locking grooves 6 are evenly spaced along the periphery of the worm gear part 42 to improve the stability of the base 32 and the disc 31 when moving vertically up and down. In this embodiment, there are four sets of locking blocks 5 and locking grooves 6.

[0045] Reference Figure 6 The bottom of the worm gear part 42 is surrounded by a limiting groove 9. At the same time, a limiting post 10 is provided inside the box body 11 in the receiving cavity 2. The limiting post 10 is inserted into the limiting groove 9 to limit and guide the rotation of the worm gear part 42, thereby improving the stability of the worm gear part 42 when rotating. In addition, in order to improve the portability of the cosmetic box, the limiting post 10 is vertically provided with a weight reduction hole 15.

[0046] Reference Figure 5 and Figure 6 A sealing ring 7 is provided at the opening of the box body 11. When the tray 31 is flipped to a position parallel to the box body 11, the sealing ring 7 surrounds and abuts against the bottom of the tray 31 to enhance the sealing performance of the box body 11 when storing cosmetics. It should be noted that the sealing ring 7 is made of soft sealant, and the upper end of the sealing ring 7 is inclined towards the outside of the box body 11. When the tray 31 is flipped to a position parallel to the box body 11, the tray 31 covers the opening of the box body 11 for storing cosmetics. As the tray 31 moves vertically downward, the space for storing cosmetics in the box body 11 gradually decreases, resulting in an increase in the pressure of the space containing cosmetics in the box body 11. At this time, the pressure of the space containing cosmetics in the box body 11 is greater than the external pressure, which pushes the upper end of the sealing ring 7 to press tightly against the bottom of the tray 31, thereby further improving the sealing effect. The inclined upper end of the sealing ring 7 is designed to keep it pressed tightly against the bottom of the tray body 31.

[0047] The implementation principle of the worm gear airtight powder box in this application embodiment is as follows: After the cosmetic is used, the user flips the tray 31 downwards, so that the tray 31 is in a horizontal state. At this time, the sealing ring 7 abuts against the bottom of the tray 31. The user places the powder puff that is not used on the tray 31 to complete the storage of the powder puff. Then the user flips the cover 12 downwards, so that the cover 12 closes the box 11. During the downward flipping process of the cover 12, the cover 12 drives the worm gear part 41 to rotate. The worm gear part 41 drives the worm wheel part 42 that cooperates with it to rotate. The worm wheel part 42 presses the base 32 downwards through the cooperation of the snap-fit ​​block 5 and the snap-fit ​​groove 6, so that the base 32 and the tray 31 move vertically downwards synchronously. The vertical downward movement of the tray 31 eliminates the gap caused by the aluminum foil being torn off, thereby improving the sealing performance of the cosmetic box. At the same time, the sealing ring 7 abuts against the bottom of the tray 31, further improving the sealing performance of the cosmetic box. The operation is simple and convenient.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
