Description

Technical Field

[0001] The utility model relates to the field of cosmetic bottle components, in particular to a self-sealing head cap for a cosmetic bottle. Background Art

[0002] In the field of cosmetic bottles, the bottles of lotion products adopt push-type caps. When the cap is pressed lightly, the lotion will flow out, which is convenient to use. However, the liquid outlet of this type of cap cannot be closed when not in use, which makes it easy for the liquid to come into contact with air and deteriorate, affecting the use of the lotion. In response to this situation, an improvement has been made to the existing head cap. For example, the Chinese utility model patent with the announcement number CN214072203U discloses a head cap body including a through hole on one side, an assembly tube and a liquid guiding tube are provided in the head cap body, one end of the assembly tube extends out from the through hole, the upper end of the liquid guiding tube extends into the assembly tube from the lower side of the assembly tube to seal with the assembly tube, and the liquid guiding tube can move up and down relative to the assembly tube; a liquid outlet tube is provided in the assembly tube, which seals with the inner wall of the assembly tube and can move along the length direction of the assembly tube, a liquid outlet is provided at the outward end of the liquid outlet tube, and an inner plug which can close the liquid outlet is provided in the assembly tube; a guide column is provided at the upper end of the liquid guiding tube along the radial direction of the liquid guiding tube, and a guide groove for the guide column to slide in is provided on the wall of the liquid outlet tube; an elastic reset member is provided between the liquid guiding tube and the head cap body to reset the head cap body after being pressed. When this type of head cap is pressed, the liquid discharge cylinder can move outward due to the cooperation of the guide groove and the guide column to release the seal of the inner plug on the liquid outlet. When the pressure is released, the liquid discharge cylinder moves inward under the action of the reset spring, guide groove and guide column, thereby allowing the inner plug to seal the liquid outlet. The guide groove is arranged obliquely, and the guide column enters into the guide groove to drive the liquid discharge cylinder to move. This structure is prone to jamming, and the liquid discharge cylinder is not smooth in resetting. Utility Model Content
