Description

Technical Field

[0001] The invention belongs to the technical field of baby products, and in particular relates to a feeding bottle capable of preventing flatulence. Background Art

[0002] In traditional baby bottles, except for the small hole on the nipple, the nipple, bottle cap and bottle body are all sealed. When the baby sucks the liquid in the bottle, the volume of the liquid in the bottle decreases, and the volume of the space inside the bottle increases, forming negative air pressure, which increases the resistance of the liquid being sucked out; at the same time, a large amount of gas will enter the bottle from the nipple, causing a large number of bubbles to mix with the liquid in the bottle; after the baby inhales these bubbling liquids, it will cause bloating, hiccups, vomiting, etc., causing discomfort to the baby. Summary of the invention

[0003] The object of the present invention is to provide an anti-flatulence feeding bottle which has a simple structure and can effectively exhaust gas.

[0004] The anti-flatulence feeding bottle provided by the present invention comprises a bottle body and a bottle cap, and is described with reference to the state where the bottle body is placed vertically, wherein:

[0005] The top of the bottle cap is provided with a soft nipple, and a spacer is provided at the bottom opening of the nipple, so that the nipple forms an independent liquid storage cavity; the nipple is provided with an air passage that runs through the bottle body;

[0006] The isolation plate is provided with a plurality of gas-liquid holes for gas and liquid to pass through, and the gas-liquid holes are arranged relatively on the left and right sides of the isolation plate;

[0007] At the gas-liquid hole, on the side close to the milk bottle, a flip sealing piece that can cover the gas-liquid hole is provided, one side of the flip sealing piece is rotatably connected to the isolation piece, and can be flipped by its own gravity, so that it can cover or open the gas-liquid hole; wherein:

[0008] When the milk bottle is tilted to pour milk, the positions of the gas-liquid holes on both sides form an upper and lower position relationship, the gas-liquid hole located at the upper side can be covered and sealed by its flip sealing piece due to gravity, and the flip sealing piece of the gas-liquid hole at the lower side is flipped open due to gravity; so that the liquid in the milk bottle can flow from the lower gas-liquid hole into the liquid storage cavity of the nipple, and at the same time, the air in the nipple will flow from the upper gas-liquid hole covered by the flip sealing piece into the milk bottle;

[0009] Since the flip sealing piece covers the gas-liquid hole from one side inside the bottle, liquid cannot enter the nipple through the upper gas-liquid hole covered by the flip sealing piece, but gas can push open the flip sealing piece and flow into the bottle, forming a one-way air valve.

[0010] In the present invention, the bottle body changes from a vertical placement state to an inclined placement state, and the liquid in the bottle body can enter the liquid storage cavity of the nipple through the gas-liquid hole located at the bottom. At the same time, the gas originally located in the nipple enters the milk bottle through the gas-liquid hole at the top because the liquid enters the nipple and occupies space. In this way, the nipple can be exhausted while the liquid enters, ensuring that the nipple can be filled with liquid without bubbles.

[0011] When the bottle body is placed upright, the liquid in the liquid storage cavity of the nipple can flow back to the bottle body through the air-liquid hole;

[0012] After the baby sucks the nipple, the liquid in the bottle decreases, and external gas enters the bottle body through the airway, balancing the air pressure in the bottle body and ensuring that the liquid in the bottle can smoothly flow into the nipple liquid storage cavity for the baby to suck.

[0013] In the present invention, the bottle body is described in a vertical state, and a slope is formed inwardly at the outer edge of the isolation plate, which forms an angle with the horizontal plane. Even if the center area of ​​the isolation plate is a structure with a larger top and a smaller bottom, the gas-liquid hole is arranged on the slope; the flip sealing plate is flipably connected to the slope, and the connection edge is located above the gas-liquid hole;

[0014] When the bottle body is placed vertically, the flip sealing piece hangs down due to gravity and separates from the gas-liquid hole;

[0015] When the bottle body tilts toward the position of the gas-liquid hole on one side and is ready to pour milk, the gas-liquid hole on that side becomes downward, and the corresponding flip sealing piece keeps drooping due to gravity, and the angle between it and the gas-liquid hole increases, so that the milk in the bottle can smoothly enter the nipple; while the gas-liquid hole on the other side becomes upward, and the corresponding flip sealing piece rests on the slope due to gravity, that is, covers the gas-liquid hole located at the upper side;

[0016] In this way, the bottle is filled with milk. When pouring, the milk can only enter the nipple from the lower air-liquid hole, and the upper air-liquid hole is sealed and cannot enter liquid, but can discharge the gas in the nipple.

[0017] In the present invention, the outer edge of the isolation plate is circular, the central area of ​​the isolation plate is an inverted circular (conical) cone, and the slope is the annular side surface of the circular (conical) cone.

[0018] In the present invention, the outer edge of the isolation piece is circular, the upper surface of the isolation piece body and the bottom of the nipple are not in contact, and there is a gap between them; the isolation piece is provided with an outer retaining wall and an inner retaining wall perpendicular to the upper surface of the isolation piece;

[0019] The top edge of the extended retaining wall is provided with a sealing edge which can fit on the bottom edge of the nipple, and the sealing edge is squeezed and fixed by the mouth of the bottle body, that is, it is located between the bottom edge of the nipple and the mouth of the bottle body;

[0020] The inner retaining wall and the outer retaining wall are concentric cylinders, the inner retaining wall is inserted into the bottom opening of the nipple and fits tightly to the inner wall of the nipple;

[0021] A circle of openings is provided in a section of the isolation plate area between the outer retaining wall and the inner retaining wall, through which gas can flow into the milk bottle;

[0022] Thus, the outer retaining wall, the isolation sheet, the inner retaining wall and the bottom of the nipple form an annular through cavity; the inner side opening of the air inlet channel on the nipple is located at the annular through cavity; in this way, only one air inlet channel needs to be provided on the nipple to realize all-round air intake in the bottle.

[0023] In the present invention, the flip sealing sheet is made of silicone, including a connecting part that is bonded to the isolation sheet, a covering part that can be folded to cover the gas-liquid hole, and a rotating part connecting the covering part and the connecting part. The connecting part, the covering part and the rotating part are integrally molded with silicone. The thickness of the rotating part is smaller than that of the covering part and the connecting part, and the thickness is 0.6mm~1mm.

[0024] In the present invention, the covering portion is coated with a metal counterweight.

[0025] The present invention adopts the structure to tilt the bottle before feeding so that the liquid can fully enter and fill the liquid storage cavity of the nipple. When feeding the child, the baby will not have bloating, hiccups, spit up, etc. due to bubbles mixed in the liquid.

[0026] The invention has a simple structure, low cost and is convenient for disassembly, maintenance and replacement of accessories. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The invention comprises a cylindrical bottle body 1 and a bottle cap 2, and a nipple 3 arranged on the bottle cap 2; the bottle body 1 and the bottle cap 2 are made of food-grade plastic; the nipple 3 is made of food-grade soft translucent silica gel.

[0034] The bottle cap 2 is open at the upper and lower ends, with internal threads on the side walls, an inverted buckle facing inward and downward at the upper opening, and a circle of inverted buckles facing outward and upward at the circular bottom edge of the nipple 3. The two inverted buckles are engaged with each other, so that the bottle cap 2 and the nipple 3 are engaged together; the mouth of the bottle body 1 is provided with an external thread corresponding to the bottle cap 2, and the bottle cap 2 is screwed on the mouth of the bottle body 1, and at the same time, the mouth of the bottle can support the bottom edge of the nipple 3 inside the bottle cap 2, strengthen the fixation of the nipple 3, and prevent water leakage; a one-way air inlet channel 8 is provided on the side of the nipple 3. Figure 1 shown.

[0035] Describe with reference to the vertical state of the bottle:

[0036] The bottom of the nipple 3 is also provided with a spacer 4 made of food-grade plastic, so that the nipple 3 forms an independent liquid storage cavity; wherein:

[0037] The outer edge of the isolation piece 4 is circular, and the upper surface of the isolation piece 4 body does not contact the bottom of the nipple 3, but is separated by a certain distance; two circles of retaining walls perpendicular to the upper surface of the isolation piece 4 are arranged on the isolation piece 4 in sequence from the outer edge to the inside, serving as an outer retaining wall 5 and an inner retaining wall 6;

[0038] The top edge of the extended retaining wall 5 is provided with a circle of horizontal sealing edge 7 which can fit on the bottom edge of the nipple 3. The sealing edge 7 is squeezed and fixed by the mouth of the bottle body 1, that is, it is located between the bottom edge of the nipple 3 and the mouth of the bottle body 1.

[0039] The inner retaining wall 6 and the outer retaining wall 5 are concentric circles, and the inner retaining wall 6 is inserted into the bottom opening of the nipple 3 and fits tightly to the inner wall of the nipple 3;

[0040] A section of the isolation plate 4 between the outer retaining wall 5 and the inner retaining wall 6 is provided with a circle of openings for gas to flow through and enter the milk bottle;

[0041] Thus, the outer retaining wall 5, the spacer 4, the inner retaining wall 6 and the bottom of the nipple 3 form an annular through cavity 9; the inner opening of the air inlet channel 8 on the nipple 3 is located at the annular through cavity 9; thus, only one air inlet channel 8 is required on the nipple 3 to realize all-round air intake in the bottle. Figure 1 shown.

[0042] The spacer 4 is also provided with a sunken concave platform in the area between the inner ring retaining wall 6. The concave platform is in the shape of an inverted circular (conical) cone with a larger top and a smaller bottom. The depth can be defined as 6 mm, and the side surface is an annular slope surface with a slope of 45°.

[0043] The isolation plate 4 is provided with two gas-liquid holes 10 for gas and liquid to pass through, and the two gas-liquid holes 10 are arranged oppositely on the left and right sides of the annular slope surface of the isolation plate 4;

[0044] At the gas-liquid hole 10, on the side facing the inside of the milk bottle, there is a flip sealing piece 11 that can cover the gas-liquid hole 10. The flip sealing piece 11 is made of food-grade silicone, and includes: a connecting part 12 that is attached to the isolation sheet 4, a covering part 13 that can be folded to cover the gas-liquid hole 10, and a rotating part 14 that connects the covering part and the connecting part; the connecting part 12, the covering part 13 and the rotating part 14 are integrally molded from silicone, and the thickness of the connecting part 12 and the covering part 13 is the same, which is 1.5mm, and the thickness of the rotating part 14 is smaller than that of the connecting part 12 and the covering part 13, which is 0.6mm; the covering part 13 is coated with a metal counterweight block, which is pre-placed inside during molding; the connecting part 12 is located on the side of the outer edge of the gas-liquid hole 10; the connecting part 12 is a single whole piece, and the covering part 13 has two pieces, which are connected to the connecting part 12 through their respective rotating parts 14, and one gas-liquid hole 10 corresponds to one covering part 13; Figure 4 shown.

[0045] The connecting portion 12 is also an annular structure, and its shape matches the shape of the outer edge area of ​​the isolation sheet 4, is nested under the isolation sheet 4, and the edge is located between the bottle mouth of the bottle body 1 and the sealing edge 7 of the isolation sheet 4, that is, it is also positioned by the extrusion of the bottle body 1 and the bottle cap 2; at the same time, a rib 15 with a barb protruding upward is provided at the connecting portion 12, and a fixing hole for the rib 15 to pass through is provided at a corresponding position of the isolation sheet 4; when the isolation sheet 4 is covered on the flip sealing sheet 11, the rib 15 is squeezed and passes through the fixing hole from bottom to top, and the barb is hooked on the upper end surface of the isolation sheet 4 around the fixing hole, so as to further fix the isolation sheet 4 and the flip sealing sheet 11 together; Figure 5 shown.

[0046] The covering portion 13 is designed to be circular and can completely cover the gas-liquid hole 10. It is coated with a stainless steel sheet as a counterweight and is integrally formed during injection molding. The rotating portion 14 is made of a thinner silicone material and can be bent and deformed arbitrarily, so the covering portion 13 can be turned over by its own gravity, thereby covering or opening the gas-liquid hole 10.

[0047] When the milk bottle is tilted to pour milk, it is tilted in a direction where one gas-liquid hole is at the bottom and the other gas-liquid hole is at the top; the gas-liquid hole at the top is covered and sealed by its corresponding flip sealing piece, which naturally falls down and covers the gas-liquid hole due to gravity; the corresponding flip sealing piece of the gas-liquid hole at the bottom naturally falls down due to gravity to be flipped open and separated from the gas-liquid hole at the bottom; in this way, the milk in the milk bottle can flow from the gas-liquid hole at the bottom into the liquid storage cavity of the nipple, and at the same time, the air in the nipple will flow from the gas-liquid hole at the top into the milk bottle; Figure 2 shown.

[0048] Since the cover is covered on the gas-liquid hole from one side inside the bottle, liquid cannot enter the nipple through the gas-liquid hole above the cover, but gas can push the cover open through the gas-liquid hole above and flow into the bottle, forming a one-way air valve. Figure 2 shown.

[0049] When the bottle is placed vertically, the two cover parts naturally fall down due to gravity, and remain separated from the air-liquid hole, and the liquid in the nipple liquid storage cavity can also flow back to the bottle through the air-liquid hole. Figure 1 shown.

[0050] After the baby sucks the nipple, the liquid in the bottle decreases, and external gas enters the bottle body through the airway, balancing the air pressure in the bottle body and ensuring that the liquid in the bottle can smoothly flow into the nipple liquid storage cavity for the baby to suck.

[0051] In this embodiment, the above-mentioned one-way air inlet channel adopts a conventional silicone one-way valve structure, that is, a funnel-shaped air hole, the air inlet is a large mouth, and the air outlet is a thin slit; when the gas flows in from the large mouth, the inner wall of the funnel is squeezed due to the air pressure, so that the thin slit of the air outlet opens to let the gas out; on the contrary, the gas flows to the air outlet, the air pressure squeezes the outer wall of the funnel, so that the air outlet is tightly closed with a thin slit, and the gas cannot enter the funnel; thereby forming a one-way air outlet.

[0052] In this embodiment, when the bottle body is changed from a normal vertical placement state to an inclined state, the liquid in the bottle body can enter the liquid storage cavity of the nipple through the gas-liquid hole at the bottom, and at the same time, the gas originally in the nipple, because the liquid enters the nipple and occupies space, enters the bottle through the gas-liquid hole at the top, so that the nipple can be filled with liquid while exhausting gas, ensuring that the nipple can be filled with liquid without bubbles, and the baby will not inhale bubbles when sucking. When the bottle body is placed vertically, the liquid in the liquid storage cavity of the nipple can also flow back to the bottle body through the gas-liquid hole.

[0053] After the baby sucks the nipple, the liquid in the nipple is sucked, and the liquid in the bottle is continuously replenished into the nipple at the same time; the liquid in the bottle decreases, and external air enters the bottle body through the air inlet of the nipple, balancing the air pressure in the bottle body and ensuring that the liquid in the bottle can smoothly flow into the nipple for the baby to suck. The design of the annular through cavity can ensure that external air can enter the bottle at any angle when the bottle is tilted at any position when a single air inlet is used.

[0054] Through the above structure and operation, the present invention tilts the bottle before feeding so that the liquid can fully enter and fill the liquid storage cavity of the nipple. When feeding the child, the baby will not have bloating, hiccups, spit up, etc. due to bubbles mixed in the liquid.

[0055] The invention has a simple structure, is easy to disassemble, has a small number of components, and is low in cost; if any component is damaged or aged, the user can disassemble and replace it by himself, and the operation is simple.
