Description

Technical Field

[0001] This utility model relates to a rotating self-priming dropper bottle. Background Technology

[0002] Chinese patent CN218143228U discloses a rotating self-priming dropper. The dropper uses a piston-type dropper with a press-to-dispense component. After a period of use, a sealing problem occurs, allowing air bubbles to enter the dropper and preventing effective liquid extraction.

[0003] Chinese patent CN208278689U discloses a cosmetic packaging bottle with high sealing performance and high positioning accuracy. The pressing assembly includes a button, a button liner, a spring, and a rubber head. The rubber head is fixed to the inner cap by a rubber head retaining sleeve. The button is fitted onto the button liner, and the spring is fitted onto the rubber head, positioned between the button liner and the rubber head retaining sleeve. The top of the rubber head has a positioning protrusion, the bottom of the button liner has a positioning hole that matches the positioning protrusion, the bottom of the rubber head has a positioning ring, and the inner cap has a positioning groove that matches the positioning ring. The top of the dropper connects to the bottom of the rubber head, and a sealing ring is provided between the dropper and the inner cap. A sealing gasket is provided between the top of the inner plug and the inner cap. However, the spring in this pressing assembly is fitted onto the rubber head, causing the rubber head and spring to jam, affecting the liquid absorption effect. Summary of the Invention

[0004] The purpose of this invention is to address the problem of poor liquid absorption in existing self-priming dropper bottles by providing a rotary self-priming dropper bottle with high sealing performance and good liquid absorption.

[0005] The purpose of this utility model is achieved as follows: A rotating self-priming dropper bottle includes a bottle and a dropper dispensing assembly. The dropper dispensing assembly includes an inner threaded cap, a spring, a pressure cap, an outer cap, a rubber tip, and a glass straw. The inner threaded cap is installed on the bottle mouth and fits into it. The inner threaded cap has an inner cylinder and an outer cylinder. The spring is fitted on the inner cylinder and pushes upward against the pressure cap. The outer cap has a raised rib on its inner wall, which matches a sliding groove on the outer wall of the inner threaded cap, forming a structure in which the outer cap can rotate axially around the inner threaded cap. The upper inner side of the outer cap has a spiral guide rail. The pressure cap is fitted on the inner cylinder and has an arc-shaped sliding shoulder that abuts against the spiral guide rail. When the outer cap is rotated, the pressure cap moves downward and returns to its original position under the action of the spring by sliding along the arc-shaped sliding shoulder through the spiral guide rail. The rubber tip is fixedly installed on the inner threaded cap through a positioning groove and a positioning ring of the inner cylinder. The rubber tip connects to the liquid in the bottle through the glass straw, and the top of the rubber tip abuts against the pressure cap.

[0006] In this invention, the pressure cap is provided with a limiting buckle, and the outer cylinder is provided with a limiting cavity, which limits the up and down movement of the pressure cap.

[0007] In this invention, the pressure cap has a pair of arc-shaped sliding shoulders, which are symmetrically arranged on the outer wall of the pressure cap.

[0008] In this invention, a pressing head is installed on the pressure cap.

[0009] This utility model includes an inner liner and an outer bottle.

[0010] In this invention, the outer contour of the outer cover is cylindrical, spherical, or olive-shaped.

[0011] The positive effects of this utility model are that the liquid dispensing component using a rubber-tipped dropper has good liquid absorption and sealing performance. The inner toothed cap is equipped with an inner cylinder and an outer cylinder, and a spring is used to sleeve the inner cylinder, which eliminates the problem of the traditional rubber tip and compression spring getting stuck, resulting in good liquid absorption stability and good sealing effect.

[0012] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0020] Reference Figures 1 to 5This embodiment 1 is a rotary self-priming dropper bottle, including a bottle 1 and a dropper dispensing assembly. The dropper dispensing assembly includes an inner thread cap 2, a spring 3, a pressure cap 4, an outer cap 5, a rubber head 6, and a glass pipette 7. A pressing head 18 is installed on the pressure cap. The inner thread cap is installed on the bottle mouth and fits with the bottle mouth. The inner thread cap has an inner cylinder 8 and an outer cylinder 15. The spring is fitted on the inner cylinder and pushes upward against the pressure cap. The outer cap has a raised rib 9 on its inner wall, which matches a sliding groove 10 opened on the outer wall of the inner thread cap, forming a structure in which the outer cap can rotate axially around the inner thread cap. The upper part of the inner side of the outer cap has a spiral guide rail 11, and the pressure cap sleeve... The cap is mounted on the inner cylinder and has an arc-shaped sliding shoulder 12 that is connected to the spiral guide rail. There is a pair of arc-shaped sliding shoulders on the cap, which are symmetrically arranged on the outer wall of the cap. When the outer cap is rotated, the cap moves downward and returns to its original position under the action of a spring by sliding along the arc-shaped sliding shoulder through the spiral guide rail. The cap is provided with a limit buckle 16 and the outer cylinder is provided with a limit cavity 17, which limits the up and down movement of the cap. The rubber head is fixedly installed on the inner thread cap through the positioning groove 13 and the positioning ring 14 of the inner cylinder. The rubber head is connected to the liquid in the bottle through a glass straw, and the top of the rubber head is in contact with the cap.

[0021] Reference Figure 6 The difference between Example 2 and Example 1 is that the bottle in Example 2 includes an inner liner and an outer bottle 19, and is mostly used for cosmetic bottles.

[0022] In this invention, rotating the outer cover clockwise causes it to slide along the curved surface via a spiral guide rail, causing the pressure cap to move downwards. This compresses the spring and simultaneously forces the rubber head to release air. When released, the spring force is released, the spring returns to its original position, the pressure cap returns to its original position, and the rubber head returns to its original position to draw in liquid. By unscrewing the dropper assembly and pressing the press head, liquid can be dispensed.
