A film made of a breathable and impermeable material is installed in the bottle cap body so that the air inside the container can pass through the film. It communicates with the air outside the container to achieve the effect of mediating the gas pressure inside and outside the container, and the adhesive film provided by the utility model is made of impermeable material, so it can ensure that the liquid in the container will not seep out, effectively solving the problem of The bottle caps in the prior art have the problems of lack of ventilation function and the guarantee of absolute safety.

In order to achieve the above purpose, the utility model provides a breathable bottle cap, which includes:

A body, which is a cap-shaped carrier, the body has an end face, a bottle cap opening and a coupling piece, the end face is arranged on the body facing the bottle cap opening, so that the body has a bottle cap opening In the inner space, the connecting part is arranged on the inner wall of the main body, and the connecting part can be a screw thread, a fastener or a buckle groove, etc., to provide a stable effect when the utility model is installed on the container opening;

A fibrous layer, which is a sheet-shaped body made of a material with radial air permeability, and the fibrous layer is arranged on the end surface of the body;

A foam layer, which is a sheet made of breathable material, the foam layer is arranged on the different side of the fibrous layer and the end surface, the foam layer has several air holes, and each air hole is set through on the side of the foam layer; and

An adhesive film layer is made of a breathable and waterproof material. The adhesive film layer is in the form of a thin film, which is arranged on different sides where the foam layer and the fiber layer are attached, and can match the size of the end surface of the body.

Through the above-mentioned technical means, the utility model is installed at the opening of the container when in use, and the air in the container can be ventilated by the film layer and the foam layer in a direction perpendicular to the end face, and then by the fiber layer in a radial direction. Breathable, the air in the container will communicate with the air outside the container through the gap between the body and the container to achieve the adjustment of the gas pressure inside and outside the container, and the adhesive film layer of the utility model is a film made of a waterproof and breathable material. Therefore, it can prevent the liquid in the container from seeping out, and effectively solve the problems that the bottle caps in the prior art lack ventilation function and cannot provide absolute safety guarantee.

detailed description

Below, in conjunction with the accompanying drawings and preferred embodiments of the utility model, the technical means adopted by the utility model to achieve the intended purpose of the utility model will be further elaborated.

The utility model is mainly a ventilating bottle cap, usually installed at the opening of the container, please refer to Figure 1, it can be seen from the figure that the venting bottle cap of the present utility model mainly includes a body 10, A fiber layer 20 , a foam layer 30 and an adhesive film layer 40 . Wherein, the body 10 is a cap-shaped carrier, the body 10 has an end face 12, a bottle cap opening 14 and a coupling piece 16, the end face 12 is arranged on the body 10 facing the bottle cap opening 14, Make the body 10 have an internal space with a bottle cap mouth 14, the joint is arranged on the inner wall of the body 10, the joint 16 can be threaded, fasteners or buckle grooves and other similar functions, to provide firmness when the utility model is installed Effect.

The fibrous layer 20 is a sheet-shaped body made of a material with a radial air permeability function. The fibrous layer 20 is arranged on the end face 12 of the body 10, so that the air in the container can pass through the fibrous layer 20 in all directions. to communicate with each other.

The foam layer 30 is a sheet made of a breathable material. The foam layer 30 is arranged on different sides where the fibrous layer 20 and the end face 12 are bonded. The foam layer 30 has several air holes 32.
