[0002] Cosmetics refer to chemical industrial products or fine chemical products that are spread on any part of the human body surface, such as skin, hair, nails, lips and teeth, by smearing, spraying or other similar methods, for the purpose of cleaning, maintenance, beautification, modification and change of appearance, or correction of human body odor and maintenance of good condition. Cosmetics are available in liquid, powder and paste forms. Among them, emulsion or latex cosmetics, such as skin care lotion and liquid foundation, are usually packaged in special bottles and are used by pressing the pressure head to squeeze the emulsion out of the nozzle. The bottle body and bottle cap of the existing structure are mostly fixed by threaded connection, which is not only not convenient and quick to assemble, but also not ideal in sealing. If the thread is loose, the pump head assembly will loosen, and it will also cause leakage.

[0003] Upon investigation, the existing Chinese patent number CN202210457139.3, "A Cosmetic Bottle," includes an outer bottle component; a pump body assembly assembled on the outer bottle component and used in conjunction with the outer bottle component, the pump body assembly including a shell component and a liquid outlet assembly mounted along the axis of the shell, and the shell component and the liquid outlet assembly forming a receiving area; and an inner bottle component, wherein a connecting unit is provided on the bottle mouth of the inner bottle component and the shell component. By assembling the pump body assembly on the outer bottle component, a receiving area is formed between the shell component and the liquid outlet assembly, and by providing a connecting unit on the bottle mouth of the inner bottle component and the shell component, the inner bottle component and the pump body component can be detachably loaded into the receiving area through the connecting unit, thereby realizing the disassembly and assembly of the inner bottle component. This cosmetic bottle also uses a threaded connection, which also has the problem of poor sealing and easy leakage due to loose threads. Utility Model Content

[0020] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 6 As shown, a cosmetic bottle with good sealing performance and quick installation includes a bottle body A, a bottle cap B and a cover 8. A pump core 3 is provided at the upper end of the bottle body A. A head cap 4 is provided at the upper end of the bottle cap B for sucking the cosmetic liquid out of the bottle body A by squeezing. A nozzle 41 is provided at the front end of the head cap 4. The upper end of the pump core 3 is fixed in the bottle cap B. The lower end of the pump body 2 is connected to a straw inserted into the cosmetic liquid in the bottle body A. The bottle cap B includes a middle section 2 and a large cover 1 arranged inside and outside. The large cover 1 is a circular sleeve. Structure, the upper and lower ends of the large cover 1 are formed with inward-folded convex edges, the middle section 2 is embedded in the inner wall of the large cover 1 and limited by the upper and lower convex edges, and the middle part of the middle section 2 is horizontally formed with a circular boss 22 for the pump core 3 to pass through and position. The upper end of the bottle body A is convexly provided with a bottle mouth 6 with a reduced diameter, and the lower end of the middle section 2 is provided with a number of elastic buckles 21 that fit tightly with the bottle mouth 6 at annular intervals. The middle section 2 is sleeved on the outside of the bottle mouth 6 and is clamped and fixed to the outer convex edge of the bottle mouth 6 by the elastic buckles 21.

[0022] The specific structure is as follows: the large lid 1 is a hollow sleeve structure, with inwardly convex upper and lower ridges 12 and 13 at the upper and lower ends of the inner wall, respectively, allowing the middle section 2 to be embedded in the inner wall of the large lid 1. The middle section 2 is divided into upper and lower parts by a circular boss 22. An annular groove 24 is formed between the inner wall of the upper section and the circular boss 22, allowing the lower end of the head cap 4 to be inserted and moved up and down. The lower wall is thickened, and eight elastic clips 21 are evenly spaced at the lower end of the middle section 2. The upper end of the bottle mouth 6 is provided with an outwardly folded annular rim 61, which the middle section 2 is fixed to by the elastic clips 21. The thinning of the middle section at the middle height gives the elastic clips greater elastic deformation ability, and combined with the outer large lid 1, it increases the overall strength of the bottle cap B and improves the sealing performance. The lower end of the elastic clips 21 is an inwardly convex arc structure, and the height of the elastic clips 21 is no less than half the height of the lower part of the middle section 2. A circular hole is provided in the middle of the circular boss 22 for the pump core 3 to pass through. A circular ring groove 23 is formed around the circular hole on the upper end surface of the circular boss 22. An upper convex ring 31 that abuts against the circular ring groove 23 and a lower convex ring 32 that abuts against the lower end surface of the circular boss 22 are provided on the outer wall of the pump core 3. An annular embedding groove 33 is formed between the upper convex ring 31 and the lower convex ring 32, so that the inner edge of the circular boss 22 of the middle section 2 can be embedded, and a sealing gasket 5 is lined between the lower convex ring 32 and the upper end surface of the bottle mouth 6.

[0023] The cover 8 is sleeved on the outside of the head cap 4 and the bottle cap B. The cover 8 is assembled from an outer cover 81 and an inner cover 82. The lower end of the inner wall of the outer cover 81 is provided with a first annular concave rib 811, and the lower end of the outer wall of the inner cover 82 is provided with a corresponding first annular convex rib 821. The inner cover 82 is tightly arranged in the outer cover 81 and fixed by the cooperation of the first annular convex rib 821 and the first annular concave rib 811.

[0024] A second annular concave rib 11 is formed on the outer wall of the upper end of the large cover 1, and a corresponding second annular convex rib 822 is formed on the inner wall of the inner cover 82. A plurality of convex ribs 823 are longitudinally spaced on the upper part of the inner wall of the inner cover 82 to abut against the upper end surface of the large cover 1.

[0025] The structure and working principle of the head cap 4 and the pump core 3 are consistent with the prior art and will not be described in detail here.

[0026] During assembly, simply align the bottle cap B with the bottle mouth 6 and press it down. The elastic buckle 21 of the middle section 2 will tightly abut and fix it with the bottle mouth 6 without the need for screw thread tightening. This makes assembly faster and has good sealing performance, effectively preventing air from entering and extending the service life of the cosmetic liquid. In addition, the pump head will not loosen, effectively preventing leakage.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
