Description

Technical Field

[0001] This application relates to the field of cosmetic technology, and more specifically, to a novel plastic dispensing container for cosmetics. Background Technology

[0002] Cosmetics are preparations (excluding soap) used on the human body to beautify, preserve, or alter a person’s appearance (e.g., for performance purposes), or to cleanse, dye, wipe, correct, or protect the skin, hair, nails, eyes, or teeth. Cosmetics are typically sold in various containers suitable for their nature, state, function, or purpose.

[0003] A search of publication number CN220045160U reveals a refillable cosmetic container. It includes a bottle body with a support column fixedly connected inside. Multiple refill bottles are movably connected inside the bottle body for storing different cosmetics. A sealing component is movably connected to the top of the bottle body, and a fixing component is fixedly connected inside the sealing component. The fixing component extends through the sealing component and is movably connected to the support column. A liquid dispensing component is movably connected between the sealing component and the support column to facilitate the outflow of liquid from the refill bottles. This invention places the refill bottles inside the bottle body, movably connects the fixing component to the support column, and drives the sealing component to be movably connected inside the bottle body. The liquid dispensing component rotates on the sealing component, facilitating the outflow of cosmetics from different refill bottles through various holes on the sealing component.

[0004] However, the height of the aforementioned cosmetic repackaging containers is fixed, which is not convenient for storing cosmetics of different heights and has insufficient adaptability. Furthermore, the top of the aforementioned cosmetic repackaging containers does not have corresponding storage space, resulting in low space utilization.

[0005] To address the aforementioned issues, this application provides a novel plastic packaging container for cosmetics. Utility Model Content

[0006] This application provides a novel plastic packaging container for cosmetics, employing the following technical solution: A novel cosmetic plastic dispensing container includes a plastic shell, a cap threadedly installed at the opening on the top surface of the plastic shell, and an extension shell nested inside the plastic shell. The bottom of the extension shell is integrally injection molded with a base plate located at the bottom of the plastic shell. A strip groove is formed on the outer wall of the extension shell, and an anti-slip surface is bonded to the inner side of the strip groove. A plum blossom knob is threadedly installed on the lower surface of the plastic shell, and one end of the plum blossom knob extends into the inner side of the strip groove, abutting against the anti-slip surface inside the strip groove.

[0007] The above technical solution enables flexible adjustment of the internal height of the plastic shell, making it suitable for cosmetic packaging at different heights.

[0008] Furthermore, the top surface of the shell cover is provided with a receiving groove, and a cross-shaped partition is integrally injection molded in the receiving groove. The receiving groove is divided into several compartments by the cross-shaped partition, and each compartment is lined with a fan-shaped sponge pad.

[0009] The above technical solutions increase space utilization and reduce contamination of the storage tank.

[0010] Furthermore, a hand-held part is fixed to the side of the shell cover, and a threaded protrusion is integrally formed on the bottom of the shell cover. An internal thread is provided on the inner side of the opening of the plastic shell corresponding to the threaded protrusion.

[0011] The above technical solution facilitates the rotation of the shell cover.

[0012] Furthermore, the lower surface of the plastic shell has two screw holes, and each screw hole is threaded with a swivel knob. The outer wall of the extension shell has two strip grooves corresponding to the swivel knobs, and the anti-slip surfaces on the inner sides of the two strip grooves are both mesh structures.

[0013] The above technical solution satisfies the limiting and locking of the extended shell.

[0014] Furthermore, protrusions are glued to both the left and right sides of the cross-shaped partition, and the two protrusions are installed in opposite directions.

[0015] The above technical solution facilitates the rotation of the shell cover.

[0016] Furthermore, the base plate has a circular structure, and the diameter of the base plate is the same as the outer diameter of the circular plastic shell.

[0017] The above technical solutions ensure the consistency of the overall structure and enhance its aesthetics.

[0018] In summary, this application includes the following beneficial technical effects: An extension cylinder shell is nested inside a plastic shell, and a base plate is integrally injection molded at the bottom of the extension cylinder shell. By pulling down the base plate, the extension cylinder shell is gradually extended to the outside of the plastic shell. Then, the Phillips head knob installed at the screw hole moves in the strip groove on the outer wall of the extension cylinder shell. This serves two purposes: firstly, it limits the extension cylinder shell to prevent it from falling off; secondly, combined with the anti-slip surface in the strip groove, it achieves threaded locking of the extension cylinder shell after any extension length. Compared with existing technologies, this allows for flexible adjustment of the height of the internal space of the plastic shell, making it suitable for cosmetic dispensing needs of different heights. The plastic housing has a cover threaded onto an opening on its top surface, and the top surface of the cover has a receiving groove with a cross-shaped partition. When the plastic housing is placed on a vanity, the receiving groove of the cover and the cross-shaped partition inside can be used to classify and place cosmetics, increasing space utilization. The fan-shaped sponge pads laid in each compartment of the receiving groove can be used to absorb cosmetic leakage and reduce contamination of the receiving groove. Attached Figure Description

[0024] This application discloses a novel plastic dispensing container for cosmetics. Please refer to [link / reference]. Figure 1 and Figure 4 The device includes a plastic shell 1, a shell cover 2 threadedly installed at the opening on the top surface of the plastic shell 1, and an extension shell 7 nested inside the plastic shell 1. The bottom of the extension shell 7 is integrally injection molded with a base plate 3, which is located at the bottom of the plastic shell 1. The outer wall of the extension shell 7 has a strip groove 9, and the inner side of the strip groove 9 is bonded with an anti-slip surface 12. The lower surface of the plastic shell 1 is threadedly fitted with a plum blossom knob 6, one end of which extends into the inner side of the strip groove 9, and the plum blossom knob 6 abuts against the anti-slip surface 12 in the strip groove 9. The inner wall of the plastic shell 1 and the outer wall of the extension shell 7 are tightly attached to each other, increasing the fit between the two. The top surface of the extension shell 7 has an open structure to meet the needs of cosmetic dispensing and storage. To facilitate the classification and storage of cosmetics, a paper divider can be movably installed inside the extension shell 7.

[0025] Please see Figure 2 and Figure 3 The top surface of the cover 2 is provided with a receiving groove 4, and a cross partition 5 is integrally injection molded inside the receiving groove 4. The receiving groove 4 is divided into several compartments by the cross partition 5, and each compartment is lined with a fan-shaped sponge pad 11. The receiving groove 4 is used to place cosmetics for easy access. The compartments facilitate the classification of cosmetics. The sponge pad 11 is used to easily absorb cosmetic exudate.

[0026] Please see Figure 1 and Figure 4 The side of the cover 2 is fixed with a hand-held part 13, and the bottom of the cover 2 is integrally formed with a threaded protrusion 8. The inner side of the opening of the plastic shell 1 is provided with an internal thread corresponding to the threaded protrusion 8. The threaded protrusion 8 and the internal thread facilitate the threaded connection between the plastic shell 1 and the cover 2.

[0027] Please see Figure 2The lower surface of the plastic housing 1 has two screw holes 10, and each screw hole 10 is threaded with a plum blossom knob 6. The outer wall of the extension housing 7 has two strip grooves 9 corresponding to the plum blossom knobs 6, and the anti-slip surfaces 12 on the inner side of the two strip grooves 9 are all mesh structures. Through the strip grooves 9 with anti-slip surfaces 12, the extension housing 7 can be easily locked by threads while satisfying the limiting function. The end face of the plum blossom knob 6 is treated with anti-slip treatment (e.g., an irregularly raised end face) to increase friction with the anti-slip surface 12.

[0028] Please see Figure 1 Both sides of the cross-shaped partition 5 are glued with protrusions, and the two protrusions are installed in opposite directions. By setting the protrusions, the shell cover 2 can be rotated by acting on the protrusions, so as to avoid the situation where the plastic shell 1 cannot be opened quickly after the hand part is damaged.

[0029] Please see Figure 1 and Figure 3 The base plate 3 has a circular structure, and the diameter of the base plate 3 is the same as the outer diameter of the circular plastic shell 1. The base plate 3 can be used as the base support of the extension cylinder 7, which is used to pull the extension cylinder 7 to adjust the height of the internal space of the plastic shell 1.

[0030] The implementation principle of this embodiment is as follows: When in use, first unscrew the cover 2 by holding part 13, and then place the cosmetics to be packaged inside the plastic shell 1. When it is necessary to adjust the height of the internal space of the plastic shell 1, pull down the bottom plate 3 to cause the bottom plate 3 to drive the extension cylinder 7 to gradually extend to the outside of the plastic shell 1. Then, the plum blossom knob 6 installed at the screw hole 10 moves in the strip groove 9 on the outer wall of the extension cylinder 7. When the height is adjusted to a suitable height, turn the plum blossom knob 6 to cause the plum blossom knob 6 to extend into the strip groove 9 and abut against the anti-slip surface 12 in the strip groove 9, so as to realize the threaded locking of the extension cylinder 7 after stretching. It is suitable for cosmetics packaging at different heights. When the plastic shell 1 is placed on the dressing table, the receiving groove 4 of the cover 2 and the cross partition 5 on its inner side can be used to classify and place cosmetics, while the fan-shaped sponge pads 11 laid in each compartment of the receiving groove 4 can be used to absorb cosmetic seepage and reduce the contamination of the receiving groove 4.

[0031] 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.
