Description

Technical Field

[0001] The utility model relates to the technical field of baby products, in particular to a balanced pressure guide piece and a sucking bottle thereof. Background Art

[0002] Newborn babies, especially those aged 0-6 months, have incomplete gastrointestinal development. They are very likely to suffer from bloating and choking when drinking milk, which is particularly harmful to babies. As the baby's rice bowl, how to prevent bloating and choking in newborn milk bottles is a big issue.

[0003] When using existing newborn baby bottles, after milk powder and hot water are added into the bottle and the lid is closed, the temperature inside the bottle is higher than the temperature outside the bottle. Once the bottle is shaken or inverted, the air inside the bottle expands due to the heat, making the pressure inside the bottle higher than the pressure outside the bottle. Since there is no obstruction inside the bottle, the milk will directly flow into the nipple cavity. Under the pressure difference and the gravity of the milk itself, the milk will spray out from the nipple opening. This can easily lead to various consequences such as excessive milk flow rate at the nipple opening being too high and the baby not having time to swallow the milk, resulting in choking during feeding.

[0004] In traditional feeding bottles, an air inlet hole is opened on one side of the nipple. When the nipple is inverted to suck milk, the air inlet hole is easily covered with milk to produce milk bubbles, which makes the baby prone to spitting up milk after sucking. In addition, milk is easily retained in the air inlet hole and is not easy to clean, which makes it easy for bacteria to grow. In addition, milk is also easy to overflow from the air inlet hole, causing milk leakage.

[0005] At present, there is a milk bottle on the market that can prevent leakage and choking, such as a dual-configuration bottle assembly with a publication number of CN105431125B, in which the exterior includes one or more radially extending grooves arranged on the bottom of the peripheral wall and connected to the channel fluid of the transverse ventilator. The one or more grooves separate a portion of the ventilator plug-in from the edge of the container so that air can flow to the transverse ventilator when the exterior is pressed against the edge. Therefore, when the bottle assembly includes the ventilator assembly, the transverse ventilator will be connected to the external fluid of the bottle assembly through the one or more grooves so that the container can be ventilated during the use of the bottle assembly. However, since the grooves are arranged on the bottom of the ventilator plug-in on the peripheral wall, when the baby sucks the milk, the milk in the container is easily leaked through the grooves, causing the milk to drip onto the baby's body or clothes.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0031] Embodiment 1:

[0032] Reference Figure 1 As shown, a sucking bottle comprises a bottle body 1, a screw cover 2, and a nipple 3. The nipple 3 is installed on the opening 11 of the bottle body 1 through the screw cover 2, wherein the screw cover 2 has an internal thread, and the outer wall of the opening 11 of the bottle body 1 has an external thread, so that the screw cover 2 is threadedly connected to the bottle body 1, and a sealing ridge 32 is provided on the bottom edge of the nipple 3, and a sealing ring groove 33 is formed between the sealing ridge 32 and the peripheral wall of the nipple 3. In this embodiment, the nipple 3 is made of silicone material, so that the sealing ring groove 33 is airtightly connected to the opening of the screw cover 2 to ensure the sealing between the nipple 3 and the screw cover 2.

[0033] Combination Figure 2 , Figure 5 As shown, further, a balanced pressure guide member 4 is arranged between the bottle body 1 and the nipple 3, and a limiting flange 44 is arranged on the outer wall of the balanced pressure guide member 4. The inner edge of the opening 11 of the bottle body 1 has a limiting groove 111 matching the limiting flange 44, so that after the screw cover 2 is screwed onto the bottle body 1, the sealing convex edge 32 of the nipple is used to press the balanced pressure guide member 4 in the limiting groove 111, so as to ensure that the balanced pressure guide member is installed stably. Since the nipple 3 is made of silicone material, the sealing convex edge 32 of the nipple 3 is air-tightly matched with the outer edge of the balanced pressure guide member, thereby improving the sealing of the bottle and preventing milk from leaking from the gap between the bottle body 1 and the screw cover 2.

[0034] Reference Figure 2 , Figure 3 As shown, more preferably, the balanced pressure guide member 4 has an outer ring 41, an inner ring 42, and an air guide tube 6, and the height of the inner ring 42 is higher than the height of the outer ring 41, so that after the bottom surface of the nipple 3 presses the outer ring 41 of the balanced pressure guide member 4, the inner ring 42 of the balanced pressure guide member 4 enters the lower opening of the nipple 3 and cooperates airtightly with the side wall of the lower opening of the nipple 3 to form a guide channel 5, and in this embodiment, the upper part of the outer wall of the inner ring 42 is an inclined surface, so that it can better fit with the surface of the nipple 3, thereby improving the sealing between the nipple 3 and the balanced pressure guide member 4.

[0035] Combination Figure 4As shown, further, a reinforcing rib 52 is provided on the bottom surface of the balanced pressure guide member 4 at the inner ring 42, and a liquid inlet hole 51 is formed between the reinforcing rib 52 and the inner ring 42. When the bottle body 1 is inverted, the milk in the bottle body 1 enters the guide channel 5 through the liquid inlet hole 51, so that the baby can suck through the nipple. Compared with the traditional straw sucking method, the present embodiment is not easy to leave residual milk, is easier to clean, and effectively prevents bacteria from breeding in the bottle. The reinforcing rib 52 is used to improve the inner ring strength of the balanced pressure guide member 4, so as to avoid deformation of the balanced pressure guide member due to excessive internal pressure during the baby's sucking process, so that a gap appears between the balanced pressure guide member 4 and the opening of the bottle body 1, and the milk flows out from the gap.

[0036] Reference Figure 2 , Figure 5 As shown, it is more preferable that the inner ring 42 is connected to the outer ring 41 to form a constant pressure channel 43, the nipple 3 is provided with an air guide hole 31, the air guide tube 6 is provided below the main body of the balanced pressure guide member 4, and is connected to the constant pressure channel 43, so that the constant pressure channel 43 is connected with the air guide hole 31 of the nipple 3. In this embodiment, the air guide tube 6 is connected to the bottom of the constant pressure channel 43. Specifically, the bottom surface of the balanced pressure guide member 4 is provided with an air guide joint 45 which is communicated with the constant pressure channel 43, the air guide tube 6 is inserted into the air guide joint 45, and the bottom of the air guide tube 6 has a one-way valve port 61, so that the air guide tube 6 is connected with the outside through the air guide hole 31, so that the outside air can enter the bottle body 1, so that during the baby's sucking process, the pressure in the bottle body 1 is kept balanced with the outside.

[0037] The inner ring 42 is connected to the outer ring 41, and is closed with the bottom surface of the nipple 3 to form the above-mentioned constant pressure channel 43, and the air guide joint 45 is located at the bottom of the constant pressure channel 43, so that after the air guide tube 6 is inserted into the air guide joint 45, the outside air can be transported to the bottom of the bottle body 1 through the air guide hole 31, the constant pressure channel 43, the air guide joint 45, and the air guide tube 6 in sequence.

[0038] Reference Figure 3 , Figure 5 As shown, further, the lower opening of the air guide hole 31 and the longitudinal section of the one-way valve port 61 are in a "V" shape, thereby effectively preventing the milk from overflowing to the outside through the air guide hole or the air guide tube.

[0039] Through the above arrangement, when the baby is sucking milk, the guide channel 5 of the balanced pressure guide member 4 is used to concentrate the milk at the nipple 3, so as to facilitate the baby's sucking and prevent the milk from entering the constant pressure channel 43, which can not only prevent the milk from contacting with the air entering through the air guide hole 31, but also prevent the milk from leaking from the gap between the screw cover 2 and the bottle body 1, and the outside air enters the bottle body through the air guide hole 31 and the air guide tube 6, so that the pressure in the bottle body 1 is balanced with the outside air, avoiding too much negative pressure in the bottle, so that the baby can drink milk smoothly, and avoid the situation where the baby chokes due to milk spraying, and because the one-way valve port 61 of the air guide tube 6 is higher than the liquid level of the milk, the air entering the bottle body 1 will not pass through the milk, thereby greatly reducing the generation of bubbles.

[0040] Reference Figure 2 , Figure 3 As shown, the present embodiment further provides a balanced pressure flow guide member 4 for the above application, the balanced flow guide member 4 comprises an outer ring 41, an inner ring 42, and an air guide tube 6, the outer ring 41 of the balanced pressure flow guide member 4 is arranged between the bottle body 1 and the nipple 3, the inner ring 42 is airtightly matched with the lower opening of the nipple 3 to form a flow guide channel 5, so that a constant pressure channel 43 is formed between the inner ring 42 and the outer ring 41, and the constant pressure channel 43 is connected with the air guide hole 31 of the nipple 3, so that when the baby sucks milk, air enters the constant pressure channel 43 through the air guide hole, which can avoid contact with the milk in the flow guide channel 5, and a constant pressure channel 43 is provided between the outer ring 41 and the inner ring 42. 3, a one-way valve port 61 is arranged at the bottom of the air guide pipe 6. In this embodiment, the lower end of the air guide pipe 6 extends to the bottom surface of the bottle body 1, so that the air in the constant pressure channel 43 enters the bottom surface of the bottle body through the air guide pipe 6, so that the milk does not contact with the air during the sucking process, thereby reducing the generation of bubbles in the milk and preventing the baby from spitting up milk after sucking. At the same time, the pressure in the bottle body 1 can be balanced, so that the baby can suck smoothly and the situation that the milk flow rate is too fast and causes the baby to choke on the milk is prevented. The one-way valve port 61 can prevent the milk from entering the air guide pipe 6, and prevent the milk from remaining in the air guide pipe 6 and being difficult to clean, thereby easily breeding bacteria and affecting the baby's health.
