Description

Technical Field

[0001] The utility model relates to a tubular liquid cosmetic bottle, in particular to a cotton brush head cosmetic bottle. Background Art

[0002] Tubular liquid cosmetic bottles primarily refer to cosmetic containers such as lip gloss bottles and mascara brushes. These bottles are primarily designed for convenient application of cosmetic liquid. Lip gloss sticks are topped with a cosmetic sponge for easy application, while mascara brushes are topped with a cosmetic brush head for easy application. After dipping the cosmetic sponge or brush head into the bottle, use the stick by simply holding it and applying it back and forth to the desired area. For example, Chinese patent application No. 201720476477.6, published on January 16, 2018, describes a utility model titled "A New Cosmetic Bottle." The cosmetic bottle comprises a cover and a container. The container comprises a bottle body, an inner stopper, and external threads at the end of the bottle body. The cover comprises an inner cap and an outer cap. The inner cap has a threaded sleeve connected to a brush stem, which in turn connects to a brush head. The brush stem and brush head move axially along the inner threads of the sleeve. The inner cap has internal threads that mesh with the external threads. However, the bottle cap structures of the above-mentioned products and similar products are less stable, the bottle models and capacities are different, the production and assembly are inconvenient, and the production costs are high. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the present invention aims to provide a cotton brush head cosmetic bottle in the art that addresses the technical problems of existing similar products, such as poor structural design, poor cap structural stability, varying bottle sizes and capacities, inconvenient production and assembly, and high production costs. This objective is achieved through the following technical solution.

[0004] The outer diameter of the inner threaded bottle mouth of the bottle cap is connected with the inner threaded bottle mouth of the bottle cap, and the inner diameter of the inner threaded bottle mouth of the bottle cap is provided with a cotton brush head assembly, one end of the cotton brush head assembly is fixedly arranged in the middle of the inner top of the bottle cap, and the other end of the cotton brush head assembly is provided with a cotton brush head with a spherical head; when the outer threaded bottle mouth of the bottle body and the inner threaded bottle mouth of the bottle cap are connected and sealed, the head of the cotton brush head partially extends out of the end of the center hole of the inner plug in the bottle body through the central hole of the inner plug, and the liquid in the bottle body contacts the head of the cotton brush head extending out of the end of the center hole of the inner plug. The aperture of the center hole of the inner plug is 4-8mm, and the outer diameter of the cotton brush head is sealed against the inner diameter of the center hole of the inner plug. The key points of its structural design are that the cotton brush head assembly includes a cotton brush head, a sleeve and a base. While the head of one end of the cotton brush head extends out of the through hole at one end of the sleeve with interference fit, the head seat of the other end of the cotton brush head is limited and fixed at the through hole at one end of the sleeve.

The second buckle on the other side of the outer diameter rib of the other end of the base is fastened and connected to the top groove inside the bottle cap. The positioning rib of the outer diameter of the base above the second buckle is fitted with the positioning groove inside the bottle cap. The end of the base inside the sleeve is against the head seat of the cotton brush head. The structural design of the cotton brush head, sleeve and base of the above-mentioned cotton brush head assembly is convenient for automated production and assembly, and provides the effect of liquid dipping and the sealing effect when the bottle cap is tightened.

[0005] The bottle body comprises an upper bottle body and a lower bottle body. The externally threaded bottle mouth at the top of the upper bottle body is connected to the internally threaded bottle mouth of the bottle cap. The bottle mouth at the bottom of the upper bottle body is ultrasonically fused to the bottle mouth at the top of the lower bottle body. The lower bottle body is replaced according to the model and capacity requirements and then installed into the upper bottle body to form an integral body.

[0006] The bottle cap comprises an inner cap and an outer cap, wherein the outer threaded opening of the bottle body is connected to the inner threaded opening of the inner cap, and the outer flange of the inner cap is glued to the stepped groove at the inner diameter of the outer cap. The double-layer structure of the bottle cap improves its shock resistance and drop resistance.

[0007] The outer diameters of the bottle body and bottle cap are correspondingly diamond-shaped, and the outer diameters of the opposite end corners of the inner bottle cap are respectively provided with limiting ribs. The limiting ribs at the inner bottle cap of the bottle cap are fitted with the inner diameter of the outer bottle cap. This structure improves the appearance and facilitates the positioning of components during the automated production and assembly process.

[0008] The bottle cap is provided with a protruding button, the top of the base extending out of the bottle cap and being inserted into the button, the button and the base being integrally connected, and an external spring being provided on the outer diameter of the base inside the button at the top of the bottle cap, one end of the spring being against a raised ring diameter on the outer diameter of the top of the base, and the other end of the spring being against the top of the inner bottle cap inside the bottle cap; when the rib on the inner diameter side of the bottom of the rotating button is aligned with the slide groove on the inner diameter side of the bottle cap, the button is pressed down and released, and the button drives the cotton brush head of the cotton brush head assembly through the base to press down the inner plug and reset, and the liquid in the bottle is sucked into the cotton brush head through the center hole of the inner plug. The above structure facilitates improving the liquid absorption effect during dipping and the sealing effect when the bottle cap is tightened. Alternatively, the bottle cap is provided with a valve stem at the top of the bottle cap, one end of the valve stem being fixedly fastened to the base inside the bottle cap, the other end of the valve stem extending out of the bottle cap and being connected to the button, and an external spring being provided on the outer diameter of the valve stem, one end of the spring being against a raised ring diameter on the outer diameter of the top of the valve stem, and the other end of the spring being against the top of the inner bottle cap inside the bottle cap.

[0009] A raised anti-rotation block is provided at the step below the externally threaded bottle opening of the bottle body, so that the bottle cap is stopped at the anti-rotation block.

[0010] The utility model has a reasonable structural design, is easy to produce, use and carry, and has a beautiful appearance. In particular, it is easy to produce and assemble automatically, and has good liquid dipping and sealing effects. It is mainly used as a cosmetic bottle with a cotton brush head, and is a structural improvement of similar products. BRIEF DESCRIPTION OF THE DRAWINGS
