[0024] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Figure 1 A structural schematic diagram of an embodiment of the utility model is shown, which relates to a ventilated film structure and an anti-inflation baby bottle. The ventilated film structure has a film layer with ventilation function. The ventilated film structure is installed at the through hole at the bottom of the bottle body, which can prevent the water in the bottle from flowing out and can ventilate the inside and outside of the bottle to achieve pressure balance inside and outside the bottle.

[0026] A ventilating film structure 1 comprises an adhesive layer 11 and a film layer for ventilation. The adhesive layer 11 is provided to connect the ventilating film structure 1 to the bottom of a feeding bottle body 2. The ventilating film structure 1 is installed at the bottom of the feeding bottle body 2. The film layer is used for ventilation to achieve pressure balance between the inside and outside of the feeding bottle body 2. At the same time, the film layer is provided to prevent leakage of liquid in the feeding bottle body. The film layer is provided on one side of the adhesive layer 11, and the other side of the adhesive layer 11 is connected to the bottom of the feeding bottle body 2.

[0027] The ventilating film structure 1 also includes a base layer 10, which is arranged on the other side of the adhesive layer 11, that is, the film layer and the base layer 10 are respectively arranged on the two sides of the adhesive layer 11, and the base layer 10 can be selected and set according to actual needs, such as whether to set other blocking structures 3 according to the through hole 20 at the bottom of the feeding bottle body 2, that is, when other blocking structures are set at the through hole 20 of the feeding bottle body 2, the ventilating film structure 1 can be not provided with the base layer 10, and the blocking structure 3 is in contact with the milk; when no other blocking structures are set at the through hole 20 of the feeding bottle body 2, the ventilating film structure 1 can be provided with the base layer 10, and the ventilating film structure 1 is in contact with the milk. The setting of the base layer 10 enables the ventilating film structure 1 to directly contact the milk in the feeding bottle body 2 without causing pollution to the milk.

[0028] The base layer 10 is made of silica gel and is a sheet structure so that the base layer 10 can be bonded to the bottom of the bottle body 2 .

[0029] The above-mentioned film layer can be a single-layer film structure. In this case, the film layer can be an E-PTFE film 12. Under this structure, the film layer is a sheet structure. The E-PTFE film 12 can allow gas to pass through, but liquid cannot pass through the holes, thereby realizing the function of the ventilated film structure 1 that is ventilated but not liquid-permeable, thereby realizing ventilation between the inside and outside of the feeding bottle; or, the film layer is a double-layer structure. In this case, the film layer includes an E-PTFE film 12 and a PE film 13. The E-PTFE film 12 is arranged on the outer side of the adhesive layer 11, and the PE film 13 is arranged on the outer side of the E-PTFE film 12. Under this structure, the E-PTFE film 12 and the PE film 13 are connected together by pressing to form a sheet structure, and the PE film 13 can also allow gas to pass through for ventilation.

[0030] The above-mentioned adhesive layer 11 is adhesive, which is used to adhere the film layer to the bottom of the bottle body 2, or to adhere the base layer 10 and the film layer together to form the ventilated film structure 1.

[0031] An anti-swelling milk bottle comprises a bottle body 2 and a ventilating film structure 1 as described above. A through hole 20 is provided at the bottom of the bottle body 2. The provision of the through hole 20 enables the milk bottle to be ventilated during feeding. The ventilating film structure 1 is provided at the through hole 20 to block the through hole 20 and ventilate during feeding. The bottle body 2 is provided with a through hole 20, which passes through the bottom of the bottle body 2 so that the inside of the bottle body 2 is connected with the outside. The shape of the through hole 20 can be circular, square, or other shapes, which can be selected according to actual needs, and no specific requirements are made here. In some feasible embodiments, the through hole 20 is coaxially arranged with the bottle body 2, so that the overall structure of the milk bottle is symmetrical and ventilation is also convenient.

[0032] In order to prevent the bottle body 2 from leaking through the through hole 20, and to enable ventilation during feeding and balance the air pressure inside and outside the bottle body 2, the ventilating film structure 1 is installed at the through hole 20 to seal the through hole 20. The ventilating film structure 1 can ventilate but not liquid, and has an oil-repellent function, so it can optimize the air circulation in the bottle body 2.

[0033] The ventilating film structure 1 is fixedly mounted on the bottom of the bottle body 2, and the fixed connection method is preferably bonding. The ventilating film structure 1 is bonded to the outer surface of the bottom of the bottle body 2 at the through hole 20 by glue. The area of ​​the ventilating film structure 1 is larger than the area of ​​the through hole 20, so that the ventilating film structure 1 can cover the through hole 20, shield the through hole 20, and block the milk inside the bottle body 2 to prevent the milk from leaking from the through hole 20. At the same time, the ventilating film structure 1 can be adhered to the bottom of the bottle body 2, so that the ventilating film structure 1 will not fall off.

[0034] In the structure of this anti-swelling baby bottle, the ventilating film structure 1 includes a base layer 10, an adhesive layer 11 arranged on one side of the base layer 10, and a film layer arranged on one side of the adhesive layer 11. The film layer is an E-PTFE film 12. The base layer 10 of the ventilating film structure 1 is bonded to the bottom of the bottle body 2. The base layer 10 contacts the milk in the bottle body 2 and will not contaminate the milk.

[0035] An anti-swelling milk bottle comprises a bottle body 2, a blocking structure 3 and the above-mentioned ventilation film structure 1. A through hole 20 is provided at the bottom of the bottle body 2. The through hole 20 is provided so that the milk bottle can be ventilated during feeding. The blocking structure 3 is provided at the through hole 20 to block the through hole 20. The blocking structure 3 is plugged into the through hole 20. The outer diameter of the blocking structure 3 is not less than the inner diameter of the through hole 20, so that when the blocking structure 3 is plugged into the through hole 20, the blocking structure 3 and the through hole 20 are interference fit, and the blocking structure 3 will not fall off from the through hole 20. In order to enable ventilation between the inside and outside of the bottle body 2, the blocking structure 3 is provided with a ventilation hole 30 for ventilation. The ventilation hole 30 is a through hole 20 that penetrates the blocking structure 3, so that the inside and outside of the bottle body 2 are connected. The ventilation film structure 1 is provided at the ventilation hole 30 to block the ventilation hole 30, and ventilation is performed during feeding.

[0036] The above-mentioned plugging structure 3 includes a plugging part and a connecting part. The plugging part is inserted into the through hole 20, the connecting part is in contact with the bottom of the bottle body 2, and the vent hole 30 is provided on the plugging part. The above-mentioned plugging part is a columnar structure so that the plugging part can be inserted into the through hole 20 at the bottom of the bottle body 2. The shape of the plugging part is adapted to the shape of the through hole 20, and the outer diameter of the plugging part is not less than the inner diameter of the through hole 20, so that when the plugging part is inserted into the through hole 20, there is no gap between the plugging part and the through hole 20, and no leakage occurs; The connecting part is a sheet structure, and the connecting part is fixedly arranged at either end of the blocking part. The diameter of the connecting part is larger than the diameter of the blocking part, so that when the blocking part is inserted into the through hole 20, the connecting part can contact the bottom of the bottle body 2 on the side of the through hole 20, thereby limiting the insertion depth of the blocking part. The shape of the connecting part can be circular, square, or other shapes, which can be selected according to actual needs. No specific requirements are made here. The connecting part is fixedly connected to the blocking part, and this connection method is preferably integrally formed.

[0037] Since the blocking structure 3 will contact the milk in the bottle body 2, the material of the blocking structure 3 is preferably silica gel.

[0038] The above-mentioned vent hole 30 is arranged along the axial direction of the blocking portion. The vent hole 30 passes through the blocking portion and the connecting portion at the same time, that is, the vent hole 30 passes through the blocking portion and the connecting portion in sequence, so that the inside and outside of the bottle body 2 are connected for ventilation. When the vent hole 30 is arranged, the vent hole 30 is coaxially arranged with the through hole 20, so that the overall structure of the bottle is symmetrical and the ventilation is uniform.

[0039] In the structure of this anti-swelling baby bottle, the ventilating film structure 1 includes an adhesive layer 11 and a film layer arranged on one side of the adhesive layer 11, and the film layer is an E-PTFE film 12 and a PE film 13. The adhesive layer 11 of the ventilating film structure 1 is bonded to the outer side of the connecting part of the sealing structure 3 to seal the vent hole 30 and realize ventilation inside and outside the baby bottle.

[0040] Of course, in the anti-swelling bottle structure, regardless of whether the blocking structure 3 is provided at the through hole 20 at the bottom of the bottle body 2, the ventilating film structure 2 may be provided with a base layer 10 or may not be provided with a base layer 10. The structure of the ventilating film structure 2 is not specifically limited here, and can be selected according to actual needs; similarly, the structure of the film layer can be a single-layer film structure or a double-layer film structure, and can be selected according to actual needs.

[0041] When the feeding bottle is in use, according to actual needs, the ventilating film structure 1 can be directly pasted on the through hole at the bottom of the bottle body 2, and then feeding can be carried out. During the feeding process, the ventilating film structure 1 is ventilated, so that the external gas enters the bottle body 2 through the ventilating film structure 1 and the through hole 20, and the air pressure inside and outside the bottle body 2 is balanced to prevent flatulence; or, when the feeding bottle is in use, the blocking structure 3 is inserted into the through hole 20, and then the ventilating film structure 1 is pasted on the outer side of the blocking structure 3 to block the air hole 30, and then feeding can be carried out. During the feeding process, the ventilating film structure 1 is ventilated, so that the external gas enters the bottle body 2 through the ventilating film structure 1 and the air hole 30, and the air pressure inside and outside the bottle body 2 is balanced to prevent flatulence.

[0042] After being used for a period of time, the ventilated film structure 1 can be replaced by pasting a new ventilated film structure 1 again, thereby achieving a high level of gas-liquid exchange and being replaceable at any time.

[0043] Due to the adoption of the above technical scheme, the ventilated film structure has a film layer, which allows air to pass through but prevents liquid from passing through, and the film layer has an oil-repellent function, so that when the ventilated film structure is fixed at the through hole at the bottom of the bottle body, external air can enter the bottle through the ventilated film structure for ventilation, thereby achieving air pressure balance inside and outside the bottle, preventing the bottle from bloating, and optimizing the air circulation in the bottle; the ventilated film structure has an adhesive layer, so that the ventilated film structure can be fixedly bonded to the through hole at the bottom of the bottle body; the ventilated film structure has a base layer, and the setting of the base layer can make the ventilated film structure contact with the milk in the bottle without contaminating the milk; the ventilated film structure can be used and attached immediately, and can be replaced at any time while achieving a high level of gas-liquid exchange, so it is easy to use.
