Aiming at the situation, in order to overcome the defects of the prior art, the utility model provides the anti-inflation and anti-leakage breathable sealing film, and the problem that the anti-inflation and anti-leakage breathable sealing film is needed to be provided is effectively solved.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides an anti-flatulence, leak protection ventilative sealing membrane, includes the adventitia, the inside fixedly connected with center membrane of adventitia, the bleeder vent has been seted up to center department of center membrane, has evenly seted up the round hole on the adventitia, and the round hole is arranged along the circumferencial direction, and the inside of round hole alternates there is the rope body.
Preferably, the shape of the outer film is annular, and the outer film is made of polyvinyl chloride.
Preferably, the shape of the central membrane is circular, and the central membrane is made of aluminum foil.
Preferably, the rope body is uniformly provided with nodes, and interference fit is adopted between the nodes and the round holes.
Preferably, the rope body is annular in shape, and is made of rubber materials.
Preferably, the upper surface and the lower surface of the outer film are respectively attached with a dustproof film, and the dustproof films are made of high-temperature-resistant opaque materials.
Compared with the prior art, the utility model has the beneficial effects that:
1) In operation, through the matched use of the arranged rope body, the nodes and the like, the rope body can be directly pulled to tighten and fix the breathable sealing film when the breathable sealing film is used, and the breathable sealing film is convenient to fix without additional tools;
2) In operation, through the adventitia and the center membrane that set up, can guarantee the intensity of ventilative sealing membrane through the aluminium foil of center membrane, avoid appearing the swell phenomenon, and the material of adventitia can make it have good pliability, is convenient for fix.

FIG. 3 is a schematic diagram of the rope structure of the present utility model;
in the figure: 1. an outer membrane; 2. a center membrane; 3. ventilation holes; 4. a round hole; 5. a rope body; 6. and (5) a node.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model; all other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The first embodiment is shown in figures 1-3, and the utility model relates to an anti-flatulence and anti-leakage breathable sealing film, which comprises an outer film 1, wherein a central film 2 is fixedly connected inside the outer film 1, ventilation holes 3 are formed in the center of the central film 2, round holes 4 are uniformly formed in the outer film 1, the round holes 4 are arranged along the circumferential direction, and ropes 5 are inserted into the round holes 4;
under the state of use, place the central membrane 2 in the bottleneck department of bottle, then push down adventitia 1 along the edge of bottleneck, make adventitia 1 parcel in the outer wall of bottleneck department, then pull rope body 5, fix adventitia 1 in bottleneck department through rope body 5, then can overlap rope body 5 on the bottleneck.
The shape of the outer membrane 1 is annular, and the outer membrane 1 is made of polyvinyl chloride;
the shape of the central membrane 2 is circular, and the central membrane 2 is made of aluminum foil;
by means of the design, the strength of the breathable sealing film can be guaranteed through the central film 2, and the flexibility of the breathable sealing film can be guaranteed through the outer film 1.
The rope body 5 is uniformly provided with the nodes 6, and the nodes 6 are in interference fit with the round holes 4;
the rope body 5 is annular in shape, and the rope body 5 is made of rubber materials;
by means of the design, when the rope body 5 is pulled, the rope body 5 drives the node 6 to move, the node 6 penetrates through the corresponding round hole 4 and then is loosened, and due to interference fit, the node 6 cannot return to the original position, and therefore the purpose of wrapping and fixing the outer membrane 1 is achieved, and the device is convenient.
The upper surface and the lower surface of the outer film 1 are respectively adhered with a dustproof film, and the dustproof films are made of high-temperature-resistant opaque materials;
by the design, when the dustproof film is not used, the dustproof film can play a good dustproof role.
