Description

Technical Field

[0001] This utility model relates to the field of injection molding cap equipment technology, specifically an injection molding cap with anti-drop and cushioning function. Background Technology

[0002] Injection-molded caps are plastic caps made using the injection molding process. The materials used to make injection-molded caps are usually plastics such as polyethylene (PE), polypropylene (PP), ABS, and PC. These materials have good processing performance, which can effectively improve the stability of the use of injection-molded caps. Due to their low price, high production efficiency, and good sealing performance, injection-molded caps are widely used for sealing various containers in the food, cosmetics, and pharmaceutical industries.

[0003] However, most existing injection-molded caps are single-layered, which makes their external drop protection insufficient. At the same time, when the injection-molded cap is dropped, its impact cushioning performance is also insufficient, which reduces the service life of the injection-molded cap. Therefore, there is an urgent need for an injection-molded cap with drop protection and cushioning function to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an injection-molded cap with anti-drop and cushioning function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an injection-molded cap with anti-drop cushioning function, comprising an injection-molded cap body for support.

[0006] A protective structure is fixedly disposed on the outer end face of the injection-molded cap body;

[0007] A fixing slot is provided at the center of the lower end face of the injection molded cover body, and sealing strips are provided at equal intervals on the lower end face of the injection molded cover body near the fixing slot.

[0008] A sealing gasket is fixedly disposed on the lower end face of the injection-molded cap body.

[0009] Preferably, the protective structure includes a protective shell, with buffer posts evenly spaced on the inner end face of the protective shell, and protective protrusions evenly spaced on the outer end face of the protective shell. Reinforcing ribs are provided inside the protective protrusions that are laterally adjacent to each other on the outer end face of the protective shell, and a wear-resistant shell is fixedly provided on the outer end face of the protective shell.

[0010] Preferably, the reinforcing rib is fitted and connected to the outer end face of the wear-resistant shell, and the reinforcing rib and the wear-resistant shell together can support and strengthen the exterior of the protective shell, thereby improving the protective strength of the exterior of the protective shell.

[0011] Preferably, the protective protrusion extends beyond the outer end face of the wear-resistant sleeve, which can effectively improve the wear resistance and protective performance of the injection-molded cap body.

[0012] Preferably, the inner end face of the protective sleeve is fixedly connected to the outer end face of the injection molded cap body through the buffer pin. The protective sleeve makes uniform point contact with the injection molded cap body through the buffer pin, which can effectively reduce the impact force on the injection molded cap body and improve the external buffering performance of the injection molded cap body.

[0013] Preferably, the sealing gasket is fixedly disposed on the lower end face of the injection-molded cap body through the fixing groove. The sealing gasket can seal the bottom of the injection-molded cap body and the protective structure, thereby forming a cavity between the protective shell and the injection-molded cap body, thus improving the drop protection and cushioning performance.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting up a protective structure, uses reinforcing ribs arranged in a mesh pattern to effectively improve the external support stability of the protective shell, thereby improving the impact resistance of the injection molded cap body when dropped. At the same time, the wear-resistant shell can provide all-round protection for the exterior of the protective shell, further improving the impact resistance. In addition, the protective protrusions on the exterior of the protective shell and the buffer pins inside the protective shell can provide sufficient cushioning for the injection molded cap body, thereby improving the protection of the injection molded cap body and thus increasing the service life of the injection molded cap body.
