Description

Technical Field

[0001] The present invention relates to the technical field of baby products, and particularly to a straw bottle. Background Art

[0002] Currently, straw bottles with gravity balls are widely used for older babies, which is convenient for babies to hold and drink independently. However, there is a common problem in the use of straw bottles on the market: when the user shakes the bottle to mix the milk powder, the air pressure inside the bottle will rise rapidly, causing the milk liquid to spurt upward along the straw under the action of pressure and finally spray out from the nipple. This phenomenon not only causes waste of milk liquid, but also may scald the user or dirty the surrounding environment. Therefore, improvement is needed. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a stable straw bottle.

[0004] The technical solution of the present invention provides a straw bottle, which includes a bottle body. A flow-blocking partition step is provided at the inner wall of the bottle body below the bottle mouth. A pressure-regulating hole is opened on the bottle body above the flow-blocking partition step, and a switch member is provided at the pressure-regulating hole.

[0005] Further, the flow-blocking partition step surrounds the inner wall of the bottle body for one week to prevent the milk liquid from directly spraying out from the pressure-regulating hole.

[0006] Further, the switch member includes two states of open and closed. When the milk bottle is shaken, the switch member is in the open state, so that the pressure-regulating hole is communicated with the outside; when in the milk-drinking state, the switch member is in the closed state to ensure the sealing performance of the milk bottle.

[0007] Further, it further includes a straw, a gravity ball and a nipple member. One end of the straw is communicated with the nipple member, and the other end extends to the bottom of the bottle body through the gravity ball. An air inlet valve is provided on the nipple member.

[0008] Further, the switch member is provided on the nipple member, and a connecting member is provided on the bottle body. The connecting member cooperates with the switch member to realize the opening and closing of the connection between the nipple member and the bottle body.

[0009] Further, the connecting member is a clamping flange. The switch member includes a rotatable collar lock and a pressure regulating switch disposed on the inner wall of the collar lock and corresponding to the pressure regulating hole. The pressure regulating switch has a sealing portion adapted to the pressure regulating hole for opening or closing the pressure regulating hole. The collar lock is provided with a clamping groove for cooperating with the clamping flange. By rotating the collar lock, the clamping groove is engaged with or separated from the clamping flange to realize the connection locking and unlocking of the nipple member and the bottle body. When in the milk-shaking state, the clamping groove of the collar lock is engaged with the clamping flange, and at the same time, the pressure regulating switch moves to a position where the pressure regulating hole is opened. When in the milk-drinking state, the clamping groove of the collar lock is engaged with the clamping flange, and the pressure regulating switch moves to a position where the pressure regulating hole is closed.

[0010] Further, the pressure regulating switch includes a moving convex block and a sliding groove connected to the side of the moving convex block facing the bottle body. The bottle body is provided with a limiting sliding block for cooperating with the sliding groove. The sealing portion is disposed in the sliding groove, and the movement of the moving convex block can drive the sealing portion in the sliding groove to move, thereby opening or closing the pressure regulating hole.

[0011] Further, the pressure regulating hole is disposed above the limiting sliding block. When the sealing portion closes the pressure regulating hole, the sealing portion abuts against the limiting sliding block.

[0012] Further, the collar lock is provided with a groove for cooperating with the moving convex block. When in the milk-drinking state, the moving convex block moves onto the groove to press the collar lock, and at the same time, the moving convex block drives the sealing portion on the sliding groove to close the pressure regulating hole.

[0013] Further, a rotational connection structure is provided between the nipple member and the bottle body. The rotational connection structure is disposed on the opposite side of the position where the switch member is located. The nipple member is rotationally connected to the bottle body through the rotational connection member. The rotational connection member includes a rotating shaft disposed on the nipple member and a corresponding shaft hole on the bottle body. The rotating shaft is rotatably assembled in the shaft hole, so that after the switch member opens the connection between the bottle body and the nipple member, the nipple member can rotate and open relative to the bottle body with the rotational connection member as the center.

[0014] After adopting the above technical solutions, the following beneficial effects are obtained:

[0015] In the present invention, by designing the pressure regulating hole to quickly release pressure during milk shaking and combining with the blocking effect of the flow resistance partition step, the risk of milk spraying is greatly reduced. After the pressure regulating hole is closed, the milk bottle remains in a sealed state, avoiding milk leakage or external contamination. While ensuring the normal use function of the straw milk bottle, the problem of milk spraying during milk shaking is effectively solved, and the safety and user experience of the product are improved.

Detailed implementation manners

[0024] The following further describes the detailed implementation manners of the present invention with reference to the accompanying drawings.

[0025] It is easily understood that according to the technical solution of the present invention, under the condition of not changing the essential spirit of the present invention, there are various structural manners and implementation manners that can be mutually replaced by those of ordinary skill in the art. Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as all of the present invention or as a limitation or restriction on the technical solution of the invention.

[0026] The orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned in this specification are defined relative to the structures shown in the respective drawings, and they are relative concepts. Therefore, they may change accordingly according to their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0027] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "attachment" 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 mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In some embodiments of the present invention, it includes a bottle body 1. A flow-blocking partition step 11 is provided at the inner wall of the bottle body 1 near the lower part of the bottle mouth. A pressure-regulating hole 12 is opened on the bottle body 1 above the flow-blocking partition step 11, and a switch member 2 is provided at the pressure-regulating hole 12.

[0029] Specifically, the bottle body 1 adopts a conventional baby bottle body structure, and the material can be food-grade materials such as PP, PPSU, or glass. The flow-blocking partition step 11 is located at the inner wall of the bottle body 1 near the lower part of the bottle mouth, and is in a ring-shaped convex structure, integrally formed with the bottle body 1 or fixed by assembly. The pressure-regulating hole 12 is opened on the side wall of the bottle body 1 above the flow-blocking partition step 11, and the aperture size can be designed according to the air pressure regulation requirements (usually 1-3 mm). The switch member 2 is installed at the pressure-regulating hole 12, and can adopt a rotary, pressing, or sliding structure to control the opening and closing of the pressure-regulating hole 12. The straw assembly includes a straw, a gravity ball, and a nipple. The straw extends to the bottom of the bottle, and the gravity ball ensures that the milk can be sucked clean.

[0030] Working principle: Milk-shaking mode (pressure regulating hole 12 is open): When the user shakes the bottle, the air pressure in the bottle rises rapidly, and the milk will surge up along the straw under the influence of pressure. At this time, the pressure regulating hole 12 is in an open state, and the high-pressure air in the bottle can be quickly discharged through the pressure regulating hole 12 to prevent the milk from spraying out of the nipple due to the sudden increase in air pressure. At the same time, the flow-blocking partition 11 can block most of the milk from rushing directly to the pressure regulating hole 12, reducing the risk of milk leakage. Drinking mode (pressure regulating hole 12 is closed): When the baby sucks the nipple, the pressure regulating hole 12 is closed to maintain the sealing inside the bottle. At this time, the straw and the gravity ball work normally, the milk can be sucked out smoothly, and the outside air enters the bottle through the air inlet valve 31 on the nipple, maintaining normal sucking pressure, and avoiding the formation of negative pressure in the bottle that causes sucking difficulties. Technical effect: 1. Effectively prevent milk spraying: The pressure regulating hole 12 quickly releases pressure when shaking the milk, combined with the blocking effect of the flow-blocking partition 11, greatly reducing the risk of milk spraying. 2. Easy to operate: The switch 2 can be switched manually, opened when shaking milk and closed when drinking, meeting the needs of different usage scenarios. 3. Good sealing: After the pressure regulating hole 12 is closed, the bottle remains sealed to prevent milk leakage or external contamination. 4. Simple structure and easy to clean: The design of the flow-blocking step 11 and the pressure regulating hole 12 does not affect the internal cleanliness of the bottle, and the switch 2 is detachable for easy and thorough cleaning. This solution effectively solves the problem of milk spraying when shaking milk while ensuring the normal use of the straw bottle, thereby improving the product safety and user experience.

[0031] In some embodiments of the present invention, the flow-blocking step 11 surrounds the inner wall of the bottle body 1 for a circle, and is used to prevent the milk from spraying directly from the pressure regulating hole 12 .

[0032] Specifically, the flow-blocking partition 11 is an annular structure, which surrounds the inner wall of the bottle body 1 and is integrally injection molded with the bottle body 1. The pressure regulating hole 12 is opened on the side wall of the bottle body 1 above the flow-blocking partition 11, with a hole diameter of 1-3mm, and the number can be 1-2, symmetrically distributed to improve the pressure relief efficiency, and the position is higher than the maximum milk liquid level in the bottle to prevent the milk from flowing out directly. The switch member 2 can adopt a rotating cover, a sliding piece or a silicone spring structure, covering the pressure regulating hole 12 and can be manually operated. For example: the rotary switch controls the opening and closing by rotating the annular component outside the bottle body 1; the sliding switch intercepts the milk by horizontally toggling the on-off annular partition of the regulating hole to prevent the milk from leaking from the pressure regulating hole 12 due to local bypass. The position of the pressure regulating hole 12 is higher than the flow-blocking partition 11, ensuring that only air is discharged but no liquid is discharged, and the pressure relief response is faster. Double protection: the flow-blocking partition 11 + the pressure regulating hole 12 work together to reduce the probability of milk spraying by more than 90% (compared with a milk bottle without such a structure). Strong compatibility: It is suitable for bottles of different capacities (150-300ml) without affecting the original straw and gravity ball functions. The flow blocking step 11 has a dead angle-free design, and the switch 2 is detachable, which meets the hygiene standards for baby products. This structure is especially suitable for straw bottles with gravity balls, solving the pain point of parents shaking milk when older babies drink milk independently.

[0033] In some embodiments of the present invention, the switch component 2 is arranged on the nipple component 3, and a connecting component is provided on the bottle body 1. The connecting component cooperates with the switch component 2 to realize the opening and closing of the connection between the nipple component 3 and the bottle body 1.

[0034] Specifically, the switch component 2 is integrated on the nipple component 3, and can adopt a rotating, snap-on or pressing structure (such as a threaded cap, an elastic snap-on or a push-pull switch), and is made of food-grade silicone or PP, and is integrally formed with the nipple or assembled separately. The connecting piece is arranged at the mouth of the bottle body 1, and matches the switch component 2. For example, if the switch component 2 is a rotating type, the connecting piece is an external thread or a slot 211 of the bottle mouth; if the switch component 2 is a pressing type, the connecting piece is a protrusion or a groove 212 on the inner wall of the bottle mouth. Through the cooperation of the switch component 2 and the connecting piece, the nipple component 3 is fixed or separated from the bottle body 1. Working principle: milk shaking mode (nipple locking + pressure regulating hole 12 opening): 1. Rotate the switch ring on the nipple (30-45 degrees) or press the switch button; 2. The pressure regulating hole 12 is opened, but the nipple component 3 still maintains a sealed connection with the bottle body 1; 3. The flow blocking step 11 blocks the milk, and the gas is quickly discharged through the pressure regulating hole 12. Drinking mode (nipple locked + pressure regulating hole 12 closed): 1. Reversely operate switch 2 to close pressure regulating hole 12; 2. Nipple 3 remains locked; 3. Maintain normal sucking through the nipple's own air inlet valve 31. Disassembly and washing mode: 1. Completely unscrew nipple 3 (at this time, pressure regulating hole 12 is completely exposed); 2. All components can be separated for cleaning.

[0035] In some embodiments of the present invention, the connecting member is a snap-fit ​​flange 13, and the switch member 2 includes a rotatable collar lock 21 and a pressure regulating switch arranged on the inner wall of the collar lock 21 and corresponding to the pressure regulating hole 12, the pressure regulating switch has a sealing portion 22 adapted to the pressure regulating hole 12, and is used to open or close the pressure regulating hole 12; the collar lock 21 is provided with a snap-fitting groove 211 cooperating with the snap-fitting flange 13, and the snap-fitting groove 211 is snap-fitted or separated with the snap-fitting flange 13 by the rotation of the collar lock 21 to realize the connection locking and unlocking of the nipple member 3 and the bottle body 1; when in the milk shaking state, the snap-fitting groove 211 of the collar lock 21 is snap-fitted with the snap-fitting flange 13, and the pressure regulating switch moves to the position of opening the pressure regulating hole 12; when in the milk drinking state, the snap-fitting groove 211 of the collar lock 21 is snap-fitted with the snap-fitting flange 13, and the pressure regulating switch moves to the position of closing the pressure regulating hole 12.

[0036] Specifically, the pressure regulating hole 12 is opened on the bottle body 1 above the flow blocking step 11, and the switch component 2 is arranged on the nipple component 3, corresponding to the pressure regulating hole 12. The switch component 2 is composed of a rotatable collar lock 21 and a pressure regulating switch, the collar lock 21 is sleeved on the outside of the nipple component 3, and the pressure regulating switch is arranged on the inner wall of the collar lock 21 and corresponds to the position of the pressure regulating hole 12.

[0037] In some embodiments of the present invention, a rotational connection structure 4 is provided between the nipple member 3 and the bottle body 1. The rotational connection structure 4 is arranged on the opposite side of the position where the switch member 2 is located. The nipple member 3 is rotationally connected to the bottle body 1 through a rotational connecting member; the rotational connecting member includes a rotating shaft provided on the nipple member 3 and a corresponding shaft hole on the bottle body 1. The rotating shaft is rotatably assembled in the shaft hole, so that after the switch member 2 opens the connection between the bottle body 1 and the nipple member 3, the nipple member 3 can rotate and open relative to the bottle body 1 with the rotational connecting member as the center.

[0038] Specifically, the nipple member 3 and the bottle body 1 are cooperatively connected through the rotational connection structure 4 and the switch member 2. On the opposite side of the position where the switch member 2 is located, the rotating shaft on the nipple member 3 is inserted into the corresponding shaft hole on the bottle body 1 to achieve rotational connection; a clamping flange 13 is provided on the bottle body 1 as a connecting member, and a card slot 211 is provided on the collar lock 21 on the nipple member 3. By rotating the collar lock 21, the card slot 211 is engaged with or separated from the clamping flange 13 to achieve locking and unlocking of the nipple member 3 and the bottle body 1.

[0039] In some embodiments of the present invention, the pressure regulating switch includes a moving convex block 23 and a sliding groove 24 connected to the side of the moving convex block 23 facing the bottle body 1. A limiting slider 14 cooperating with the sliding groove 24 is provided on the bottle body 1. The sealing portion 22 is arranged in the sliding groove 24. The movement of the moving convex block 23 can drive the sealing portion 22 in the sliding groove 24 to move, thereby opening or closing the pressure regulating hole 12.

[0040] Specifically, the moving convex block 23 of the pressure regulating switch is fixedly connected to the sliding groove 24. The sliding groove 24 faces the bottle body 1. The limiting slider 14 on the bottle body 1 cooperates with the sliding groove 24, and the sealing portion 22 is installed in the sliding groove 24. When the moving convex block 23 moves, it can drive the sealing portion 22 in the sliding groove 24 to move, realizing the opening and closing control of the pressure regulating hole 12. By driving the sealing portion 22 in the sliding groove 24 to slide precisely along the limiting slider 14 by the moving convex block 23, the linear opening and closing control of the pressure regulating hole 12 is realized. Specifically, it is manifested as: the pushing and pulling action of the moving convex block 23 → converted into the horizontal linear movement of the sliding groove 24 → driving the sealing portion 22 to accurately align with or leave the pressure regulating hole 12. The limiting slider 14 restricts the movement track of the sliding groove 24 to prevent deflection. The structure of the sliding groove 24 **: ensures that the sealing portion 22 only moves along the set direction. When the sliding groove 24 moves upward → the sealing portion 22 disengages from the pressure regulating hole 12 → the pressure relief channel is opened

[0041] ; when the sliding groove 24 moves downward → the sealing portion 22 presses against the pressure regulating hole 12 → completely sealed, converting the user operation into a linear sealing movement, and realizing reliable opening and closing through mechanical guidance.

[0042] In some embodiments of the present invention, the connecting member is a clamping flange 13. The switch member 2 includes a rotatable collar lock 21 and a pressure regulating switch disposed on the inner wall of the collar lock 21 and corresponding to the pressure regulating hole 12. The pressure regulating switch has a sealing portion 22 adapted to the pressure regulating hole 12 for opening or closing the pressure regulating hole 12. The collar lock 21 is provided with a clamping groove 211 adapted to the clamping flange 13. By rotating the collar lock 21, the clamping groove 211 is engaged with or separated from the clamping flange 13 to realize the connection locking and unlocking of the nipple member 3 and the bottle body 1. When in the milk-shaking state, the clamping groove 211 of the collar lock 21 is engaged with the clamping flange 13, and at the same time, the pressure regulating switch moves to a position where the pressure regulating hole 12 is opened. When in the milk-drinking state, the clamping groove 211 of the collar lock 21 is engaged with the clamping flange 13, and the pressure regulating switch moves to a position where the pressure regulating hole 12 is closed.

[0043] Specifically, the clamping groove 211 of the collar lock 21 is engaged with the clamping flange 13 of the bottle body 1 to fixedly connect the nipple member 3 and the bottle body 1. The moving convex block 23 of the pressure regulating switch moves, causing the sealing portion 22 to move along the sliding groove 24 to open the pressure regulating hole 12. At this time, the inside of the bottle is communicated with the outside. During the milk-shaking process, air can enter and exit through the pressure regulating hole 12 to balance the air pressure inside the bottle and prevent the milk liquid from spraying out of the nipple due to the air pressure difference. Milk-drinking state: The clamping groove 211 remains engaged with the clamping flange 13 to ensure the stable connection between the nipple member 3 and the bottle body 1. The moving convex block 23 moves to the position of the groove 212 on the collar lock 21, and a part of the structure of the moving convex block 23 is embedded in the groove 212. Through the close cooperation between the two, the groove 212 is squeezed, thereby pressing the collar lock 21 tightly. After the collar lock 21 is pressed tightly, the connection between its clamping groove 211 and the clamping flange 13 of the bottle body 1 becomes tighter, and the relative position between the nipple member 3 and the bottle body 1 is further fixed, making the connection between the nipple member 3 and the bottle body 1 more stable. At the same time, the moving convex block 23 drives the sealing portion 22 in the sliding groove 24 to move to close the pressure regulating hole 12 and ensure the sealing performance of the milk bottle. At this time, the baby sucks the milk liquid through the nipple, and the air inlet valve 31 allows air to enter the bottle to maintain the air pressure balance inside the bottle. When it is necessary to open the milk bottle for cleaning and other operations, the moving convex block 23 moves away from the groove 212 on the collar lock, so that the collar lock 21 can rotate freely. Rotating the collar lock 21 separates the clamping groove 211 from the clamping flange 13. Since the nipple member 3 and the bottle body 1 are connected by the rotating connection structure 4, the nipple member 3 can be rotated and opened relative to the bottle body 1 with the rotation axis as the center.

[0044] Optionally, the sealing portion 22 can be (1) a basic sealing member, material: food-grade silicone, structure: cylindrical sealing head; (2) an enhanced sealing member, composite structure: main body: silicone sealing layer (contacting liquid), matrix: POM plastic skeleton (enhancing rigidity), double-lip edge design (main sealing lip + auxiliary dust-removing lip).

[0045] Technical effects:

[0046] 1. Significant effect of preventing milk from spraying out: the flow-blocking step 11 cooperates with the pressure regulating hole 12 and the switch 2 to balance the air pressure by opening the pressure regulating hole 12 when shaking the milk, and at the same time prevents the milk from spraying out directly from the pressure regulating hole 12, effectively solving the problem of milk splashing when shaking milk with a traditional bottle, reducing milk waste and keeping the use environment clean.

[0047] 2. Good sealing performance: When drinking milk, the pressure regulating switch closes the pressure regulating hole 12, and combined with the sealing structure of the nipple 3, it prevents milk leakage and the entry of external air and impurities, ensures the quality and hygiene of the milk, and avoids problems such as bloating caused by the baby inhaling air.

[0048] 3. Improved ease of use: The nipple 3 and the bottle body 1 can be quickly locked and unlocked through the switch 2, and can be rotated open, which is convenient for assembly, disassembly and cleaning; the design of the straw and the gravity ball enables the baby to drink milk smoothly regardless of the posture; the two state switching operations of the switch 2 are simple, which is convenient for parents to use.

[0049] 4. The rotating connection structure 4 is combined with the snap-on structure, and the compression design of the groove 212 of the collar lock 21 and the movable protrusion 23 is coordinated to ensure that the nipple piece 3 is firmly connected to the bottle body 1 and will not be easily separated during use. At the same time, the rotating opening design does not affect the overall structural strength, thereby extending the service life of the bottle.

[0050] In some embodiments of the present invention, the pressure regulating hole 12 is disposed above the limiting slider 14 . When the sealing portion 22 closes the pressure regulating hole 12 , the sealing portion 22 is lowered onto the limiting slider 14 .

[0051] Specifically, the pressure regulating hole 12 is vertically located directly above the limit slider 14 (with a spacing of 2-3 mm). When the sealing part 22 is closed, it contacts the pressure regulating hole 12 (forming an annular sealing line) and the upper surface of the limit slider 14 (forming a supporting surface) at the same time. The contact mode: "abutment" refers to the contact between the bottom of the sealing part 22 and the surface of the limit slider 14. The limit slider 14 bears more than 60% of the sealing pressure to prevent the sealing part 22 from deforming. The limit slider 14 serves as a mechanical stopper to ensure the precise positioning of the sealing part 22.

[0052] In some embodiments of the present invention, a groove 212 cooperating with the moving protrusion 23 is provided on the collar lock 21. When in the milk drinking state, the moving protrusion 23 moves to the groove 212 to press the collar lock 21. At the same time, the moving protrusion 23 drives the sealing part 22 on the slide groove 24 to close the pressure regulating hole 12.

[0053] Specifically, the depth of the groove 212 matches the height of the moving convex block 23. The groove 212 has a bevel angle (to achieve a smooth transition). The stroke of the moving convex block 23 is synchronized with the opening and closing of the pressure regulating hole 12. There are two working mechanisms: (1) Mechanical locking: The convex block engages with the groove 212; (2) Sealing drive: The displacement of the convex block is directly transmitted to the sealing part 22. One-key dual control function:

[0054] A single operation simultaneously increases the pre-tightening force of the collar lock 21 and seals the pressure regulating hole 12 with the sealing part 22. Through precise mechanical linkage, this design integrates leak-proof sealing and structural locking into a single reliable action, solving the core contradiction that baby products need to be both easy to operate and absolutely safe.

[0055] In the present invention, by designing the pressure regulating hole 12 to quickly release pressure during milk shaking and combining with the blocking effect of the flow blocking step 11, the risk of milk spraying is greatly reduced. After the pressure regulating hole 12 is closed, the milk bottle remains in a sealed state, avoiding milk leakage or external contamination. While ensuring the normal use function of the straw milk bottle, the problem of milk spraying during milk shaking is effectively solved, improving the safety of the product and the user experience.

[0056] The above are only the principles and preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, based on the principles of the present invention, several other variations can also be made, which should also be regarded as the protection scope of the present invention.
