Description

Technical Field

[0001] The utility model relates to the field of containers, in particular to a spray-proof milk bottle. Background Art

[0002] Newborn babies, especially those aged 0-6 months, have incomplete gastrointestinal development. The probability of bloating and choking when drinking milk is very high, and choking is particularly harmful to babies. As the baby's rice bowl, how to prevent bloating and choking in newborn baby bottles is a big issue. During the use of existing newborn baby bottles, when milk powder and hot water are added to 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 in 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 in the bottle, the milk will flow directly into the nipple cavity. Under the pressure difference and the gravity of the milk itself, the milk will spray out from the nipple opening, which can easily lead to various consequences such as burns during feeding, and choking due to the high flow rate of milk at the nipple opening.

[0003] Ordinary baby bottles have valves for air return through the nipples, and the air inlet holes are easily covered by milk, producing milk bubbles, and the nipples are easily blocked, which cannot reduce or eliminate bubbles in the bottle. When the baby bottle with air return function is inverted, the milk is more likely to spray out of the nipple under the action of gravity, increasing the risk of the baby choking on the milk.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Example 1

[0033] like Figure 1 As shown, a spray-proof milk bottle of the present embodiment includes a bottle body 1, a cover body 2 and a nipple 3. A round hole is provided on the cover body 2, and the nipple 3 is arranged in the round hole on the cover body 2. The cover body 2 is detachably arranged on the bottle body 1. Specifically, the bottle body 1 and the cover body 2 are both provided with threads, and the bottle body 1 and the cover body 2 are connected by threads.

[0034] A sealing ring 5 is provided between the bottle body 1 and the cover body 2, and a diaphragm 4 is provided between the sealing ring 5 and the cover body 2. The diaphragm 4 divides the space inside the bottle into two parts. A first valve plate 7 is provided on the diaphragm 4. The sealing ring 5 is connected to a constant pressure tube 8. A buffer cavity 6 is formed between the diaphragm 4 and the nipple 3. A first opening 41 is provided on the diaphragm 4. A first valve plate 7 is provided at the first opening 41. The first valve plate 7 can close the first opening 41 under normal conditions. When the bottle is inverted, the first valve plate 7 is used to block or slow down the milk in the bottle body 1 from entering the buffer cavity 6. The first valve plate 7 is also used to deform when the pressure difference between the bottle body 1 and the buffer cavity 6 is greater than a preset value, so as to open the first opening 41;

[0035] The sealing ring 5 is connected to the constant pressure tube 8. Specifically, a sleeve 53 is provided on the sealing ring 5, and the constant pressure tube 8 is sleeved in the sleeve 53. A valve 51 is provided in the sleeve 53 or the constant pressure tube 8 to prevent milk from flowing back. The valve 51 can also be provided at one end of the constant pressure tube 8 away from the sleeve 53 to prevent milk from flowing back.

[0036] When the pressure in the bottle increases or the pressure in the buffer cavity decreases, the first valve plate 7 flips up under the action of the pressure difference, and the milk in the bottle needs to first pass through the first opening 41 of the diaphragm 4 into the buffer cavity 6, and will not be directly sprayed out from the opening of the nipple 3. Only when the pressure in the buffer cavity 6 increases to a certain level, the milk will flow out or spray out from the opening of the nipple 3, and the flow rate will be much lower than that in the case where the buffer cavity 6 is not set, thereby significantly improving safety.

[0037] The diaphragm 4 is provided with a buckle 42, and the first valve sheet 7 is clamped with the diaphragm 4 through the buckle 42. The first valve sheet 7 covers the top of the first opening 41. The first valve sheet 7 and the diaphragm 4 are provided with a pressure relief channel 43. When the baby sucks the pacifier rapidly, the pacifier may be squeezed, increasing the pressure in the buffer cavity. At this time, the milk in the buffer cavity 6 can flow back to the bottle through the pressure relief channel 43 by itself, releasing part of the pressure, thereby preventing the milk from being ejected at high speed from the opening of the pacifier 3, causing the baby to choke on the milk due to insufficient swallowing.

[0038] like Figure 2 As shown, the thickness of the first valve sheet 7 gradually decreases from the fixed end side (i.e., the side close to the buckle 42) to the free end side (i.e., the side away from the buckle 42). When the bottle is inverted, the first valve sheet 7 can effectively block the milk from spraying out. When the baby sucks, the thinner part of the first valve sheet 7 is deformed first, leaving the spacer 4, and opening the first opening 41. The milk can quickly enter the buffer cavity 6 from the bottle body 1, and then flow out through the opening of the nipple 3, thereby reducing the resistance of the baby to suck milk.

[0039] like Figure 4 As shown, a second valve plate 71 is provided at the pressure relief channel 43. The second valve plate 71 is used to limit the milk inside the bottle body 1 from entering the buffer cavity 6. The second valve plate 71 is also used to open the pressure relief channel 43 when the pressure inside the buffer cavity 6 is greater than a preset value. Specifically, the second valve plate 71 covers the opening of the pressure relief channel 43 toward the bottle body 1, which can effectively prevent the milk from entering the buffer cavity 6 from the bottle body 1 through the channel 43.

[0040] The first valve plate 7 and the second valve plate 71 may be arranged on the sealing ring 5 .

[0041] like Figure 1-Figure 4 As shown, there can be a variety of installation and matching relationships between the spacer 4, the sealing ring 5, the first opening 41, the first valve plate 7, the pressure relief channel 43, and the second valve plate 71. Those skilled in the art can reasonably combine or replace them based on the contents of the utility model, which are not listed here one by one.

[0042] like Figure 1 As shown, an air return channel 52 is provided on one side of the sealing ring 5. When the baby is drinking milk, air can enter the air return channel 52 through the gap between the threads of the bottle body 1 and the cover body 2, and then enter the bottle body through the valve 51, so that the pressure inside and outside the bottle body is balanced to prevent suction. The valve 51 can also prevent milk from entering the air return channel 52. When the bottle body is inverted for feeding, the outlet of the constant pressure tube 8 is located above the milk. The air will not pass through the milk when entering the bottle, which effectively reduces the generation of bubbles.

[0043] Example 2

[0044] like Figure 5 As shown, similar to Example 1, the difference is that the anti-bubble component includes an elastic liner 11, the elastic liner 11 is preferably made of silica gel, the elastic liner 11 is arranged in the bottle body 1, the opening of the elastic liner 11 is fitted with the sealing ring 5, and the bottle body 1 is provided with a channel for external air to enter and exit the gap between the bottle body 1 and the elastic liner 11. Specifically, the bottom of the bottle body 1 is provided with a second opening 12. When the baby drinks milk, as the milk in the bottle decreases, the elastic liner 11 generates negative pressure. Under atmospheric pressure, the volume of the elastic liner 11 is also reduced accordingly, so that the pressure in the elastic liner 11 will not be too different from the external atmospheric pressure, preventing the nipple from sucking and holding it, and at the same time, the air does not need to enter the bottle again, avoiding the generation of bubbles and preventing the newborn baby from flatulence. The second opening 12 can allow air to smoothly enter and exit between the elastic liner 11 and the bottle body 1 without affecting the deformation of the elastic liner 11. In addition to providing the second opening 12 on the bottle body 1 , a gap may be left at the contact surface between the bottle body 1 and the elastic liner 11 , and air from the outside enters between the bottle body 1 and the second opening 12 through the gap, which can also achieve a similar effect.

[0045] The purpose of setting the constant pressure tube 8 or setting the elastic liner 11 is to prevent too much negative pressure from being generated in the container when feeding a small baby with a bottle, so that the baby can drink milk smoothly, and at the same time, prevent bubbles from being generated to prevent the baby from bloating. Either of the two sets of structures can be selected. In addition to the constant pressure tube 8 and the elastic liner 11, there are other structures in the prior art that can prevent excessive negative pressure in the container and prevent bubbles from being generated. Those skilled in the art can reasonably combine or replace them in combination with the contents of the utility model, which are not listed here one by one.

[0046] When a constant pressure tube 8 or an elastic liner 11 is provided, when the bottle is used upside down, milk is more likely to flow out of the nipple 3 due to the high pressure in the container and the action of gravity. The provision of a spacer 4 to form a buffer cavity 6 can just solve this problem, and can effectively reduce the speed and pressure of the milk outflow, making the baby safer during the sucking process.

[0047] Preferably, the bottle body 1, the cover body 2 and the spacer 4 are all made of hard materials.

[0048] Preferably, the nipple 3, the sealing ring 5 and the first valve plate 7 are all made of silicone.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
