Description

TECHNICAL FIELD

[0002] Cosmetic bottle is the packaging bottle for storing cosmetics, which is usually composed of a bottle head, a bottle cap and a bottle body. Referring to the technical solution disclosed in ZL202021074247.5, a high-beak round-corner cover plastic hose assembly includes a bottle head, a bottle cap and a bottle body. The bottle head has a beak extrusion cone column on the upper end, and the beak extrusion cone column has a central liquid outlet hole communicating with the bottle body. The bottle cap is buckled on the upper end of the bottle head. In this technical solution, the beak extrusion cone column of the bottle head is provided with a central liquid outlet hole communicating with the bottle body. The central liquid outlet hole is conical, and the upper end hole diameter of the central liquid outlet hole is smaller than the lower end hole diameter. In this way, the amount of cosmetics poured out is reduced through the small hole at the upper end of the central liquid outlet hole, thereby avoiding waste caused by excessive amount of cosmetics poured out.

[0003] However, although the above technical solution reduces the pouring speed of cosmetics through the small hole at the upper end of the central liquid outlet hole, some users may habitually squeeze the bottle body to assist the flow of cosmetics during the pouring process. This unconscious squeezing action may instantaneously increase the pressure in the bottle, causing the cosmetics to rapidly fill the central liquid outlet hole under pressure drive and quickly break through the flow rate limit formed by the design of the central liquid outlet hole diameter, and finally flow out of the central liquid outlet hole at a speed far exceeding the expected speed, thereby causing the flow rate reduction effect expected to be achieved by the design of the central liquid outlet hole to be poor, making it difficult for the user to accurately control the use of the pressurized and rapidly flowing cosmetics, and resulting in waste of cosmetics.
