Description

Technical Field

[0001] This utility model relates to the field of dropper bottles, and more particularly to a dropper bottle. Background Technology

[0002] Drip bottles are a common type of liquid packaging container, typically consisting of a glass or plastic body and a rubber dropper. Their core function is to precisely control the amount of liquid dispensed and added by squeezing and releasing the dropper tip. They are widely used in fields requiring precise dosage, such as cosmetics, pharmaceuticals, and laboratory reagents. A key feature is their small, sealed opening, making them easy to carry and store.

[0003] However, most dropper bottles are equipped with droppers that are inconvenient to use. The air bladder at the top is easily accidentally squeezed and draws out liquid directly. In addition, after the dropper draws out liquid, a large amount of liquid often remains on its outer wall, which is easy to spill out and cause waste, reducing the practicality of the dropper bottle.

[0004] Therefore, those skilled in the art have provided a dropper bottle to solve the problems mentioned in the background section. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies and provide a dropper bottle. This dropper bottle, through a structure that combines a pressure rod, an abutment, and the dropper body, replaces the traditional design where the upper air bladder of the dropper is exposed. During operation, the pressure rod must be actively pressed to squeeze the air bladder at the upper end of the dropper body through the abutment, effectively preventing improper liquid aspiration due to accidental contact with the air bladder. This makes liquid aspiration more controllable and convenient, improves upon the inconvenience of traditional structures, and further enhances the practicality of the dropper bottle.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A dropper bottle includes a bottle body and a shoulder sleeve. The shoulder sleeve is fixedly connected to the upper end of the bottle body, and a bottle cap is threadedly connected to the upper end of the bottle body. A pressure rod is provided at the upper end of the bottle cap, and an abutment is fixedly connected to the lower end of the pressure rod. A dropper body is provided at the lower end of the inner wall of the bottle cap, and a stopper is provided at the lower end of the inner wall of the bottle cap. An inner liner is sleeved inside the bottle body, and an inner connecting ring is fixedly connected to the upper end of the inner wall of the bottle body. Through the above technical solution, the dropper bottle replaces the traditional dropper's exposed upper air bladder design with a matching structure of the pressure rod, abutment, and dropper body. During operation, the pressure rod must be actively pressed to squeeze the air bladder at the upper end of the dropper body through the abutment to draw liquid. This effectively prevents improper liquid drawing caused by accidental contact with the air bladder, making liquid drawing more controllable and convenient. It improves the inconvenience of traditional structures and further enhances the practicality of the dropper bottle. Relying on the matching design of the inner liner, inner connecting ring, and stopper, when the dropper body draws liquid and is retracted, the liquid remaining on its outer wall can be scraped or guided back into the inner liner through contact with the stopper and inner connecting ring, avoiding residual liquid dripping to the outside and causing waste, improving liquid utilization, and further enhancing the practicality of the dropper bottle.

[0007] Furthermore, a base is fixedly connected to the lower end of the bottle body; The above technical solution uses a base to stabilize the bottle and prevent it from shaking, thus improving stability.

[0008] Furthermore, the bottle body is made of PMMA, and the dropper body is made of PP. Through the above technical solutions, PMMA has high transparency, is lightweight and easy to process, making the bottle more beautiful and practical, and also reducing the processing difficulty of the bottle. PP is corrosion resistant, non-toxic and odorless, which is conducive to the dropper body to absorb various liquids.

[0009] Furthermore, the stopper is made of LDPE, and the inner liner is made of PE. Through the above technical solutions, LDPE exhibits excellent moisture resistance and good chemical stability, which is beneficial for sealing and storing liquids in various dropper bottles.

[0010] Furthermore, the base is made of the same material as the shoulder sleeve, which is ABS, and the pressure rod and the abutment are both made of glass. Through the above technical solutions, ABS has high impact resistance and toughness, which improves the overall strength of the dropper bottle. The use of glass for the pressure rod and the abutment can maintain a certain strength and also have a decorative function.

[0011] Furthermore, the bottle cap is made of the same material as the bottle body, which is PMMA; Through the above technical solutions, PMMA has high transparency, is lightweight, and is easy to process. When combined with the bottle body, it improves the overall strength without appearing obtrusive or affecting the aesthetics.
