Description

Technical Field

[0001] The utility model belongs to the technical field of cosmetic bottles, in particular to a cosmetic bottle with high sealing performance. Background Art

[0002] Cosmetic bottles refer to bottles or containers used to package and hold cosmetics, usually made of materials such as glass, plastic or metal, with different shapes, sizes and design styles to suit different types and brands of cosmetic products.

[0003] Sealing is an important indicator of cosmetic bottles. The quality of sealing will directly affect the shelf life of cosmetics. A conventional cosmetic bottle with high sealing performance, such as that disclosed in Patent No. ZL202020774727.6, comprises a cap, an outer cap, an inner cap, a cover sheet, a bottle body, and an inner liner. The outer cap has an opening at the top, and the cap is inserted into the opening at the top of the outer cap. Two symmetrical arc-shaped grooves are provided at the lower inner side of the outer cap, the inner cap is provided with an inner ring and an outer ring, the inner ring is located on the inner side of the outer ring, an arc-shaped strip is provided on the outer side of the outer ring, and an inner thread is provided on the inner side of the inner ring. The outer cap is fixed to the inner cap by snapping the arc-shaped strip with the arc-shaped groove, the mouth of the bottle body is provided with an external thread, the top of the bottle body is provided with a support ring, the mouth of the inner liner is provided with a flange, the inner liner is fixed to the bottle body by snapping the flange with the support ring, the cover sheet covers the mouth of the inner liner for sealing, and the inner cap is installed on the bottle body by screwing the internal thread with the external thread. In this technical solution, the upper part of the flange is smooth and flat, in the shape of an annular platform, and has a large contact area with the cover sheet, so that the sealing effect is better under the pressure of the inner cover.

[0004] Among them, the pressure generated by the inner cover mainly relies on the locking force generated by the cooperation between the internal thread on the inner cover and the external thread at the mouth of the bottle body. The threaded connection may loosen when subjected to external vibration, impact or torsional force, which will reduce the sealing effect between the cover and the flange. The sealing performance needs to be improved. Utility Model Content

[0024] Example 1: As Figures 1 to 4 shown, a highly sealed cosmetic bottle includes a bottle body 1, an inner container 2, and an upper cover 3 covering the upper end of the bottle body 1. An installation groove 11 and a circular ring 12 surrounding the installation groove 11 are provided on the upper end surface of the bottle body 1. An external thread is provided on the outer side surface of the circular ring 12. The inner container 2 is arranged in the installation groove 11 and the circular ring 12. A connection groove 31 is provided on the lower end surface of the upper cover 3, and an internal thread is provided on the inner wall of the connection groove 31. The connection groove 31 is threadedly connected to the circular ring 12.

[0025] In this embodiment, a card slot 13 is provided on the side surface of the bottle body 1. The upper end of the card slot 13 penetrates through the upper end surface of the bottle body 1. A sliding groove 32 and a sliding block 33 are provided on the side surface of the upper cover 3. The lower end of the sliding groove 32 penetrates through the lower end surface of the upper cover 3.

[0026] When the upper cover 3 is covered on the bottle body 1, by sliding the sliding block 33 downward, part of the sliding block 33 extends out of the sliding groove 32 and extends into the card slot 13. At this time, the upper cover 3 cannot rotate relative to the bottle body 1, avoiding loosening between the upper cover 3 and the bottle body 1; when it is necessary to open the bottle body 1, by sliding the sliding block 33 upward, the sliding block 33 disengages from the card slot 13. At this time, the upper cover 3 can be rotated to open the bottle body 1.

[0027] Example 2: As Figure 3 and Figure 4 shown, the rest is the same as in Example 1. The difference is that a first magnet 4 is provided at the lower end or the bottom of the card slot 13, and a first iron block 5 is fixedly provided at the lower end of the sliding block 33. When the sliding block 33 extends into the card slot 13, the first magnet 4 attracts the first iron block 5, avoiding the possible up and down sliding of the sliding block 33 when affected by external vibrations, impacts, or torsional forces, etc., and having better stability. Preferably, a first groove 131 is provided at the lower end of the card slot 13, the first magnet 4 is fixedly arranged in the first groove 131, a second groove 331 is provided at the lower end of the sliding block 33, and the first iron block 5 is fixedly arranged in the second groove 331.

[0028] In this embodiment, a second magnet 6 is provided at the upper end of the sliding groove 32, and a second iron block 7 is fixedly provided at the upper end of the sliding block 33. When the sliding block 33 disengages from the card slot 13, the second magnet 6 attracts the second iron block 7, avoiding the downward sliding of the sliding block 33 under the action of gravity and having better stability. Further, a third groove 321 is provided at the upper end of the sliding groove 32, the second magnet 6 is fixedly arranged in the third groove 321, a fourth groove 332 is provided at the upper end of the sliding block 33, and the second iron block 7 is fixedly arranged in the fourth groove 332.
