Description

Technical Field

[0001] The invention belongs to the technical field of baby products, and in particular relates to an anti-flatulence feeding bottle. 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, 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 sheet is provided with a positioning hole at the center, and a plurality of hollow areas are provided around the positioning hole to allow liquid to flow through;

[0007] The isolation sheet is provided with a closing sheet that can cover the hollow area, and a gravity swing arm is provided at the center of the bottom of the closing sheet; the gravity swing arm is inserted downward from the top surface of the isolation sheet and passes through the positioning hole of the isolation sheet, and is located at the bottom surface of the isolation sheet; the gravity swing arm can swing with the positioning hole as the rotation center, thereby driving the closing sheet to swing, so that a part of the closing sheet can be attached to the isolation sheet, while another part of the closing sheet can be separated from the isolation sheet;

[0008] The sealing sheet is also provided with a plurality of one-way air holes, and when the liquid in the bottle body enters the liquid storage cavity of the nipple, the air in the liquid storage cavity of the nipple can enter the bottle body through the hollow area of ​​the isolation sheet through the one-way air holes;

[0009] Among them, the bottle body changes from a vertical placement state to an inclined placement state, and the closing piece changes from a horizontal state to a vertical state; at this time, the gravity swing arm swings down due to gravity as the bottle body tilts, and uses the positioning hole as the seesaw fulcrum to drive the closing piece to tilt; even if the closing piece is in a vertical state, its upper part presses the isolation piece tightly, and its lower part will be driven to tilt up and leave the isolation piece due to the downward swing of the gravity swing arm; in this way, the liquid in the bottle body can enter the nipple through the hollow area of ​​the lower part of the isolation piece; at the same time, the gas originally located in the nipple, because the liquid enters the nipple and occupies space, enters the bottle through the one-way air hole of the closing piece and the hollow area of ​​the isolation piece, so that the liquid can be taken into the nipple and the air can be discharged at the same time, ensuring that the nipple can be filled with liquid without bubbles.

[0010] When the bottle body is placed upright, the liquid in the liquid storage cavity of the nipple can also flow back to the bottle body through the one-way air hole.

[0011] In addition, 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.

[0012] 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;

[0013] The top edge of the extended retaining wall is provided with a circle of sealing edge that can fit on the bottom edge of the nipple 3, 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;

[0014] 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;

[0015] A section of the isolation plate area between the outer retaining wall and the inner retaining wall is provided with a circle of openings for liquid and gas to flow through;

[0016] 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.

[0017] In the present invention, the isolation sheet is provided as a sunken concave platform in the area between the inner circle retaining walls, the positioning hole is located at the center of the area, and a plurality of hollow areas are provided in the area and surround the positioning hole.

[0018] In the present invention, the sealing sheet is made of silicone, has a circular edge, and is in a concave arc shape as a whole. A vertical downward gravity swing arm is arranged at the center of the bottom, and a counterweight block is wrapped inside the gravity swing arm. When the bottle is placed vertically, the circular edge of the sealing sheet can be just placed on the edge of the concave platform of the isolation sheet.

[0019] In the present invention, the gravity swing arm is inserted downward from the top of the isolation sheet and passes through the positioning hole of the isolation sheet, and is located at the bottom of the isolation sheet; the gravity swing arm is designed to be a square sheet, the width of the square is greater than the diameter of the positioning hole, and the wider part is a thin sheet of soft silicone that can be squeezed and folded; the width of the connection between the gravity swing arm and the closing sheet is less than the square width and less than the diameter of the positioning hole, forming a waisted shape, so that the connection can swing in the positioning hole. During installation, the wider part of the gravity swing arm is squeezed and deformed to pass through the positioning hole, and the wider part rebounds after passing through, so that the closing sheet cannot be separated from the isolation sheet.

[0020] 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.

[0021] The invention has the advantages of simple structure, low cost and convenient maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] 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.

[0028] 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.

[0029] 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:

[0030] The isolation sheet 4 is provided with a circular opening at the center thereof, serving as a positioning hole 10;

[0031] 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;

[0032] 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.

[0033] 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;

[0034] A section of the spacer 4 between the outer retaining wall 5 and the inner retaining wall 6 is provided with a circle of openings for liquid and gas to flow through;

[0035] 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.

[0036] The isolation sheet 4 is provided as a sunken concave platform in the area between the inner ring retaining wall 6, and the positioning hole 10 is located at the center of the area. A number of hollow areas 13 are provided around the positioning hole 10 in the area to allow liquid to flow through.

[0037] The isolation sheet 4 is provided with a closing sheet 11 which can cover the hollow area 13. The closing sheet 11 is made of food-grade silicone. The edge of the closing sheet 11 is circular and the whole is in a concave arc shape. A vertical downward gravity swing arm 12 is provided at the center of the bottom; the gravity swing arm 12 is coated with a stainless steel counterweight block and can be formed by double-material injection molding; when the bottle is placed upright, the circular edge of the closing sheet 11 can be just placed on the edge of the concave platform of the isolation sheet 4; the closing sheet 11 is also provided with a plurality of one-way air holes, so that when liquid enters the nipple 3, the air in the nipple 3 can enter the bottle body 1.

[0038] The gravity swing arm 12 is inserted downward from the isolation plate 4 and passes through the positioning hole 10 of the isolation plate, and is located at the bottom surface of the isolation plate 4; the gravity swing arm 12 can be designed as a square sheet, the width of the square is greater than the diameter of the positioning hole 10, and the wider part is a thin sheet of soft silicone that can be squeezed and folded; the width of the connection between the gravity swing arm 12 and the closing plate 11 is less than the square width, and less than the diameter of the positioning hole 10, forming a waisted shape, so that the connection can swing in the positioning hole 10. During installation, the wider part of the gravity swing arm 12 is squeezed and deformed to pass through the positioning hole 10, and the wider part rebounds after passing through, so that the closing plate 11 cannot be separated from the isolation plate 4. Figure 2 shown.

[0039] Thus, the gravity swing arm 12 can swing with the position of the positioning hole 10 as the rotation center, thereby driving the closing plate 11 to swing, so that a part of the closing plate can be attached to the isolation plate, while the other part can be separated from the isolation plate; the separated area can allow the liquid in the bottle to enter the nipple. Figure 3 shown.

[0040] The one-way air hole and one-way air inlet channel mentioned above adopt a conventional silicone one-way valve structure, that is, a funnel-shaped air hole with a large air inlet and a thin slit at the air outlet. When gas flows in from the large mouth, the air pressure squeezes the inner wall of the funnel, causing the thin slit at the air outlet to open and allow gas to escape. On the contrary, when the gas flows toward the air outlet, the air pressure squeezes the outer wall of the funnel, causing the air outlet to be tightly closed with a thin slit, and gas cannot enter the funnel. This forms a one-way air outlet.

[0041] In this embodiment, when the bottle body is changed from a normal vertical placement state to an inclined state, the closing piece is changed from a horizontal state to a vertical state; at this time, the gravity swing arm swings down due to gravity as the bottle body tilts, and the positioning hole is used as the seesaw fulcrum to drive the closing piece to tilt; even if the closing piece is in a vertical state, its upper half is pressed against the isolation piece, and its lower half will be driven to tilt up and leave the isolation piece due to the downward swing of the gravity swing arm; in this way, the liquid in the bottle body can enter the nipple through the hollow area of ​​the lower half of the isolation piece; and at the same time, the gas originally located in the nipple, because the liquid enters the nipple and occupies space, enters the bottle through the one-way air hole of the closing piece and the hollow area of ​​the isolation piece, so that the nipple can be filled with liquid and exhausted at the same time, 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 nipple liquid storage cavity can also flow back to the bottle body through the one-way air hole.

[0042] 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.

[0043] 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.

[0044] The invention has a simple structure, is easy to disassemble, has a small number of components and a low cost; if any component is damaged or aged, the user can disassemble and replace it by himself, and the operation is simple.
