[0004] As a PP environmentally friendly rubber-tipped dropper suitable for injection molding of the present invention, preferably, the rubber tip passes through the through hole of the inner cover 2, and the clamping platform is limited inside the inner cover.

[0005] As a PP environmentally friendly rubber-tipped dropper suitable for injection molding of the present invention, preferably, the dropper is screwed onto the internal thread opening of the inner cover through an external thread.

[0006] As a PP environmentally friendly rubber-tipped dropper suitable for injection molding of the present invention, preferably, the PP content of the rubber tip is greater than 80%.

[0007] As a PP environmentally friendly rubber-tipped dropper suitable for injection molding of the present invention, preferably, the inner cover and the dropper are made of pure PP material.

[0008] As a PP environmentally friendly rubber-tipped dropper suitable for injection molding of the present invention, preferably, the total PP content of the rubber tip, the inner cover and the dropper exceeds 95%.

[0009] As a PP environmentally friendly rubber-tipped dropper suitable for injection molding of the present invention, preferably, the rubber head is integrally formed by an injection molding process.

[0010] Compared with the prior art, the present invention has the following beneficial effects: The PP content of the rubber head is over 80%, which reduces the use of POE, an elastic material, and has a feel comparable to that of a rubber rubber head. The lid and dropper are made of pure PP. The PP content of the entire dropper is over 95%, meeting the requirements of a single material and making it easy to recycle and reuse. The rubber head can be molded using an injection molding process, which has high yield and low cost. BRIEF DESCRIPTION OF THE DRAWINGS
