Description

Technical Field

[0001] The present invention belongs to the technical field of baby products, and in particular relates to a ventilation film structure and an anti-bloating milk bottle. Background Art

[0002] For babies aged 0 - 3 months, during feeding, they may vomit or choke on milk due to swallowing a large amount of air in a short time. This is an important problem for novice mothers. In the design of traditional anti-bloating milk bottles, there are loopholes. That is, gas-liquid exchange only occurs when the silicone valve piece is open (this situation will surely occur during each sucking and swallowing process of the baby, which will make the baby use more force to suck out the milk, and long-term use may cause the problem of underbite; in traditional milk bottles, holes are opened at the bottom of the round cup body, and a silicone plug is inserted to achieve balance with the air inhaled and entered through the nipple at the top, so as to balance the internal and external air pressures and achieve the anti-bloating function. After the silicone is sterilized by steam or boiled, it often gets damaged structurally, resulting in liquid leakage from the milk bottle; silicone can be used for 0 - 6 months at a time. After long-term use, pits will form on the surface of the silicone, hiding dirt and grime. Summary of the Invention

[0003] In view of the above problems, the present invention provides a ventilation film structure and an anti-bloating milk bottle to solve the above or other previous problems existing in the prior art.

[0004] To solve the above technical problems, the technical solution adopted by the present invention is: a ventilation film structure, including an adhesive layer and a film layer for air exchange. The film layer is disposed on one side of the adhesive layer so that the film layer is pasted on the bottom of the milk bottle through the adhesive layer.

[0005] Further, it also includes a base layer, and the base layer is disposed on the other side of the adhesive layer.

[0006] Further, the film layer is an E-PTFE film or a combination of an E-PTFE film and a PE film.

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Figure 1 The structural schematic diagram of an embodiment of the present invention is shown. This embodiment relates to a ventilation film structure and an anti-expansion milk bottle. The ventilation film structure has a film layer with a ventilation function. The ventilation film structure is installed at the through hole at the bottom of the milk bottle body, which can not only prevent the water in the milk bottle from flowing out, but also ventilate between the inside and outside of the milk bottle to achieve pressure balance between the inside and outside of the milk bottle.

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

[0027] The ventilation film structure 1 further includes a base layer 10. The base layer 10 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 both sides of the adhesive layer 11. The base layer 10 can be selected according to actual needs. For example, it can be selected whether to set other blocking structures 3 according to the through hole 20 at the bottom of the milk bottle body 2. That is, when other blocking structures are set at the through hole 20 of the milk bottle body 2, the ventilation film structure 1 may not be provided with the base layer 10, and the blocking structure 3 contacts the milk liquid. When no other blocking structures are set at the through hole 20 of the milk bottle body 2, the ventilation film structure 1 may be provided with the base layer 10, and the ventilation film structure 1 contacts the milk liquid. The setting of the base layer 10 enables the ventilation film structure 1 to directly contact the milk liquid in the milk bottle body 2 without polluting the milk liquid.

[0028] The material of the above-mentioned base layer 10 is silica gel, and the base layer 10 is a sheet structure for bonding with the bottom of the milk bottle body 2.

[0029] The above-mentioned thin film layer can be a single-layer film structure. In this case, the thin film layer can be an E-PTFE film 12. In this structure, the thin film layer is a sheet structure. The E-PTFE film 12 can allow gas to pass through, but liquid cannot pass through the holes, realizing the function of the ventilation thin film structure 1 to allow ventilation but not liquid passage, and realizing the air exchange between the inside and outside of the feeding bottle; or, the thin film layer is a double-layer structure. In this case, the thin film layer includes an E-PTFE film 12 and a PE film 13. The E-PTFE film 12 is provided 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. In this structure, the E-PTFE film 12 and the PE film 13 are connected together by pressing to form a sheet structure. The PE film 13 can also allow gas to pass through for air exchange.

[0030] The above-mentioned adhesive layer 11 is an adhesive, which bonds the thin film layer to the bottom of the feeding bottle body 2, or bonds the base layer 10 and the thin film layer together to form the ventilation thin film structure 1.

[0031] An anti-swelling feeding bottle includes a bottle body 2 and the ventilation thin film structure 1 as described above. A through hole 20 is provided at the bottom of the bottle body 2. The setting of the through hole 20 enables the feeding bottle to perform air exchange during the feeding process. The ventilation thin film structure 1 is arranged at the through hole 20 to block the through hole 20 and perform air exchange during the feeding process. The bottle body 2 is provided with a through hole 20 that penetrates the bottom of the bottle body 2, enabling the inside and outside of the bottle body 2 to communicate. The shape of the through hole 20 can be circular, square, or other shapes, which can be selected according to actual needs and will not be specifically required here. In some feasible embodiments, the through hole 20 is coaxially arranged with the bottle body 2, making the overall structure of the feeding bottle symmetrical and facilitating ventilation.

[0032] In order to prevent the bottle body 2 from leaking liquid through the through hole 20, and also to enable air exchange during the feeding process to balance the air pressure inside and outside the feeding bottle body 2, the ventilation thin film structure 1 is installed at the through hole 20 to block the through hole 20. The ventilation thin film structure 1 can allow ventilation but not liquid passage, and has an oil-repellent function, which can optimize the air circulation inside the bottle body 2 of the feeding bottle.

[0033] The ventilation thin film structure 1 is fixedly installed at the bottom of the bottle body 2. The preferred fixed connection method is bonding. The ventilation thin film structure 1 is bonded to the outer side of the bottom of the bottle body 2 through an adhesive, located at the through hole 20. The area of the ventilation thin film structure 1 is larger than the area of the through hole 20, enabling the ventilation thin film structure 1 to cover the through hole 20, block the through hole 20, and block the milk liquid inside the bottle body 2 to prevent the milk liquid from leaking out through the through hole 20. At the same time, the ventilation thin film structure 1 can be pasted on the bottom of the bottle body 2 to prevent the ventilation thin film structure 1 from falling off.

[0034] Under the structure of this anti-expansion milk bottle, the ventilation film structure 1 includes a base layer 10, an adhesive layer 11 provided on one side of the base layer 10, and a film layer provided on one side of the adhesive layer 11. The film layer is an E-PTFE film 12. The base layer 10 of the ventilation film structure 1 is adhered to the bottom of the bottle body 2, and the base layer 10 contacts the milk liquid in the bottle body 2 without contaminating the milk liquid.

[0035] An anti-expansion milk bottle includes a bottle body 2, a plugging structure 3, and the ventilation film structure 1 as described above. A through hole 20 is provided at the bottom of the bottle body 2. The setting of the through hole 20 enables the milk bottle to exchange air during the feeding process. The plugging structure 3 is provided at the through hole 20 to plug the through hole 20. The plugging structure 3 is inserted into the through hole 20. The outer diameter of the plugging structure 3 is not less than the inner diameter of the through hole 20, so that when the plugging structure 3 is inserted into the through hole 20, the plugging structure 3 and the through hole 20 are in interference fit, and the plugging structure 3 will not fall off from the through hole 20. In order to enable the inside and outside of the bottle body 2 to exchange air, the plugging structure 3 is provided with a ventilation hole 30 for air exchange. The ventilation hole 30 is a through hole 20 that penetrates the plugging 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 plug the ventilation hole 30 and exchange air during the feeding process.

[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, and the connecting part contacts the bottom of the bottle body 2. The ventilation 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 liquid leakage will occur; the above-mentioned connecting part is a sheet structure, and the connecting part is fixedly arranged at any end of the plugging part. The diameter of the connecting part is greater than the diameter of the plugging part, so that when the plugging part is inserted into the through hole 20, the connecting part can contact the bottom of the bottle body 2 on the periphery of the through hole 20 to limit the insertion depth of the plugging part. The shape of the connecting part can be circular, square, or other shapes, which can be selected according to actual needs and are not specifically required here. The connecting part and the plugging part are fixedly connected, and this connection method is preferably integrally formed.

[0037] Since the plugging structure 3 will contact the milk liquid in the bottle body 2, therefore, the material of the plugging structure 3 is preferably silicone.

[0038] The above-mentioned ventilation hole 30 is arranged along the axis direction of the plugging part. The ventilation hole 30 penetrates the plugging part and at the same time penetrates the connecting part, that is, the ventilation hole 30 sequentially penetrates the plugging part and the connecting part, so that the inside and outside of the bottle body 2 are connected for air exchange. When the ventilation hole 30 is set, the ventilation hole 30 is coaxially arranged with the through hole 20, so that the overall structure of the milk bottle is symmetrical and the air exchange is uniform.

[0039] Under the structure of this anti-swelling milk bottle, the ventilation film structure 1 includes an adhesive layer 11 and a film layer provided on one side of the adhesive layer 11. The film layer is an E-PTFE film 12 and a PE film 13. The outer side of the connecting part between the adhesive layer 11 of the ventilation film structure 1 and the plugging structure 3 is adhesively bonded to plug the ventilation hole 30 and realize the air exchange between the inside and outside of the milk bottle.

[0040] Of course, in the structure of the anti-swelling milk bottle, whether the plugging structure 3 is provided at the through hole 20 at the bottom of the milk bottle body 2 or not, the ventilation film structure 2 can be provided with a base layer 10, or neither of them needs to be provided with a base layer 10. Here, the structure of the ventilation film structure 2 is not specifically limited 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, which can be selected according to actual needs.

[0041] When the milk bottle is in use, according to actual needs, the ventilation film structure 1 can be directly pasted at the through hole at the bottom of the bottle body 2, and then feeding can be carried out. During the feeding process, the ventilation film structure 1 conducts air exchange, so that the external air enters the inside of the milk bottle body 2 through the ventilation film structure 1 and the through hole 20, balancing the air pressure inside and outside the bottle body 2 and preventing flatulence; or, when the milk bottle is in use, the plugging structure 3 is inserted into the through hole 20, and then the ventilation film structure 1 is pasted on the outer side of the plugging structure 3 to plug the ventilation hole 30, and then feeding can be carried out. During the feeding process, the ventilation film structure 1 conducts air exchange, so that the external air enters the inside of the milk bottle body 2 through the ventilation film structure 1 and the ventilation hole 30, balancing the air pressure inside and outside the bottle body 2 and preventing flatulence.

[0042] After the ventilation film structure 1 is used for a period of time, it can be replaced, and a new ventilation film structure 1 can be re-pasted, realizing high-level gas-liquid exchange and being replaceable at any time.

[0043] Due to the above technical solutions, the ventilation film structure has a film layer that can allow air to pass through but not liquid, and the film layer has an oil-repellent function. When the ventilation film structure is fixed at the through hole at the bottom of the milk bottle body, the external air can enter the inside of the milk bottle through the ventilation film structure for air exchange, realizing the balance of air pressure inside and outside the milk bottle and preventing the milk bottle from swelling, and optimizing the air circulation inside the milk bottle; the ventilation film structure has an adhesive layer so that the ventilation film structure can be fixedly bonded at the through hole at the bottom of the milk bottle body; the ventilation film structure has a base layer, and the setting of the base layer can make the ventilation film structure contact with the milk liquid inside the milk bottle without causing pollution to the milk liquid; the ventilation film structure can be pasted immediately when in use, realizing high-level gas-liquid exchange and being replaceable at any time, which is convenient to use.

[0044] The above has described the embodiments of the present invention in detail, but the above content is only the preferred embodiments of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
