Description

Technical Field

[0001] This utility model belongs to the technical field of aluminum-plastic composite cover, and in particular relates to an environmentally friendly aluminum-plastic composite cover. Background Technology

[0002] Plastic products are consumables in daily life, and China consumes a large amount of them every year. While providing convenience to consumers, excessive use and inadequate recycling of plastic products have also caused serious energy and resource waste and environmental pollution.

[0003] Currently, most caps used on glass bottles are made of aluminum caps and plastic gaskets, which are fused together and are difficult to separate during later recycling. Utility Model Content

[0004] The purpose of this utility model is to provide an environmentally friendly aluminum-plastic composite cap, which solves the problem that most caps used on glass bottles are currently made of aluminum caps and plastic pads, which are fused together and are difficult to separate during later recycling.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an environmentally friendly aluminum-plastic composite cover, comprising a first cover body, a limiting plate, and a second cover body. A circular hole is formed on the upper surface of the first cover body. The limiting plate is disposed on the first cover body and abuts against its upper surface. A connecting post is fixedly connected to the bottom surface of the limiting plate. The connecting post is disposed within the circular hole and engages with it. A positioning screw is fixedly connected inside the connecting post. The second cover body is disposed inside the first cover body and slides with it. A positioning block is fixedly connected to the bottom end of the second cover body. The positioning screw passes through the second cover body and is threadedly connected to the positioning block. A sealing soft plug is fixedly connected to the bottom surface of the second cover body and is disposed around the positioning block. A limiting hole is formed on one side of the first cover body. One end of the limiting hole passes through the connecting post and communicates with the other side of the first cover body. A limiting rod is inserted into the limiting hole and engages with the connecting post.

[0007] The second cover has sliders fixedly connected to both sides, and the inner wall of the first cover has grooves on both sides. The sliders are set in the grooves and slide in cooperation with the grooves.

[0008] Both sides of the first cover are provided with mating grooves, which are located below the limiting hole. Both ends of the limiting rod are fixedly connected with mating arc rods, which are "L" shaped. One end of the mating arc rod is located in the mating groove and slides in contact with the mating groove.

[0009] The inner side of the bottom end of the first cap is provided with a threaded groove; this facilitates the fastening or removal of the first and second caps from the bottle opening.

[0010] The first cover, the mating arc rod, and the limiting rod are all made of aluminum alloy, while the limiting plate, the connecting column, the second cover, and the positioning screw are all made of plastic.

[0011] This utility model has the following beneficial effects:

[0012] This invention comprises a first cap, a mating arc rod, a limiting rod, a limiting plate, a connecting post, and a second cap. The inner side of the bottom of the first cap has a threaded groove, which allows the first and second caps, along with the sealing plug, to be fastened to the bottle opening. The threaded groove engages with the bottle opening's threads to achieve repeated sealing, effectively maintaining the bottle's seal while facilitating opening. Under the action of the mating groove, the mating arc rod is straightened along the groove, allowing the limiting rod to be removed from the limiting hole, releasing its restriction on the connecting post. This allows the limiting plate to be rotated, and under the constraint of the slider, the positioning screw is disconnected from the second cap. This enables the limiting plate and the second cap to be completely removed from the first cap, facilitating separation and recycling, and reducing environmental impact.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
