Description

Technical Field

[0001] This utility model relates to the field of baby bottle product technology, and in particular to a baby bottle with a venting function. Background Technology

[0002] Traditional baby bottles have the problem of not allowing air to escape during feeding. As milk is sucked out of the nipple, negative pressure forms inside the bottle, causing the nipple to collapse and making feeding difficult. When the suction is too strong, insufficient or slow air escape can occur, causing significant inconvenience for the baby. To address this, baby bottles with air escape functions have been invented. For example, Chinese utility model patent CN202322099689.5 discloses a baby bottle with an air escape function. This bottle has a top air escape hole on the nipple and a side air escape valve on the side wall of the bottle. The top air escape hole remains closed when not subjected to external force. After the baby sucks in the liquid, negative pressure forms inside the bottle. External air pressure forces open the top air escape hole, balancing the internal and external air pressure. Combined with the side air escape hole, this achieves both air intake and exhaust functions, ensuring smooth air escape and solving the problems of traditional baby bottles. However, this bottle has the following problems: First, the side vent valve is directly fixed to the bottle body, which is generally thin, making it easy for the vent valve to loosen or even fall off. If the vent valve falls off, it may be swallowed by a child, posing a safety hazard. Second, in order to solve the problem of the bottle being inconvenient to hold when preparing formula due to the high temperature, an additional handle is usually required, which makes the product structure more complex and increases the cost. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a baby bottle with a novel vent valve structure that is simpler in structure, more rational in design, more securely fixed with the vent valve, and does not require an additional handle.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a baby bottle with a novel air return valve structure, comprising a bottle body, a bottle cap, and a nipple, wherein the nipple is fixed to the bottle cap, and the bottle cap is fixed to the bottle body; an air valve hole is provided on the side wall of the bottle body, and an air return valve is provided in the air valve hole to form an air return structure to the bottle body; it also includes an air valve protective sleeve, the air return valve is fixed to the air valve protective sleeve, the air valve protective sleeve is tightly clamped to the bottle body, and the air return valve is opposite to the air valve hole; the air return valve is embedded and fixed in the air valve hole, so that the air valve protective sleeve covers the air valve hole, and the air inlet of the air return valve is exposed from the air valve protective sleeve.

[0005] Furthermore, a fixing groove is provided on the outer wall of the bottle, and the valve protective sleeve is embedded and fixed in the fixing groove.

[0006] Furthermore, the valve hole is located in the fixed groove and in the upper part of the bottle.

[0007] Furthermore, the return valve is fixed at one end near the valve protective sleeve. A through hole is provided on the valve protective sleeve opposite to the return valve. The return valve passes through the through hole and is embedded in the valve hole fixed in the bottle body, so that the two ends of the valve protective sleeve overlap each other and are locked and fixed to the bottle body.

[0008] Preferably, the valve protective sleeve is made of soft rubber and is wrapped around the outer side wall of the bottle.

[0009] Furthermore, a top air vent is provided on the nipple to facilitate air return and prevent the nipple from being sucked flat due to insufficient air return.

[0010] Preferably, the nipple is an eccentric nipple, with the top air hole located away from the nipple tip.

[0011] Furthermore, it also includes an eccentric dust cover with a shape that matches the nipple structure. After the dust cover is placed on the nipple, it covers the top air hole and the nipple head together.

[0012] This invention features a valve hole on the side wall of the bottle for installing a return air valve. The return air valve itself is secured by a valve protective sleeve. The protective sleeve is encircled before the return air valve is inserted into the valve hole, creating a double-fixed structure that tightly secures the valve to the bottle. This design achieves side return air while making the valve installation more stable, preventing loosening and leakage, and eliminating the risk of children swallowing it, thus eliminating safety hazards. Furthermore, the valve protective sleeve, securely fastened to the bottle, can also serve as a grip when preparing formula, preventing burns from high temperatures. This eliminates the need for an additional handle, simplifying the structure and reducing costs. Attached Figure Description

[0017] In the diagram, 1 is the bottle body, 11 is the fixing groove, 12 is the air valve hole, 2 is the bottle cap, 3 is the nipple, 31 is the top air return hole, 4 is the dust cover, 5 is the air valve protective sleeve, and 6 is the air return valve. Detailed Implementation

[0018] In this embodiment, refer to Figures 1-4The baby bottle with the novel air return valve structure includes a bottle body 1, a bottle cap 2, and a nipple 3. The nipple 3 is fixed to the bottle cap 2, and the bottle cap 2 is fixed to the bottle body 1 by threads. An air valve hole 12 is provided on the side wall of the bottle body 1. An air return valve 6 is provided in the air valve hole 12 to form an air return structure to the inside of the bottle body 1. It also includes an air valve protective sleeve 5. The air return valve 6 is fixed to the air valve protective sleeve 5. The air valve protective sleeve 5 is tightly clamped to the bottle body 1, and the air return valve 6 is opposite to the air valve hole 12. The air return valve 6 is embedded and fixed in the air valve hole 12, so that the air valve protective sleeve 5 covers the air valve hole 12, and the air inlet of the air return valve 6 is exposed from the air valve protective sleeve 5.

[0019] A fixing groove 11 is provided on the outer side wall of the bottle body 1, and the valve protective sleeve 5 is embedded and fixed in the fixing groove 11.

[0020] The air valve hole 12 is located within the fixing groove 11 and in the upper half of the bottle body 1. This prevents water in the bottle warmer from seeping into the bottle and contaminating the milk during warming, which could be caused by the air return valve being located at the bottom. The air return valve being located on the side wall of the bottle body 1 effectively avoids most of the warming water level in the bottle warmer, preventing such problems.

[0021] The return valve 6 is fixed at one end near the valve protective sleeve 5. A through hole is also provided on the valve protective sleeve 5 opposite to the return valve 6. The return valve 6 passes through the through hole and is embedded in the valve hole 12 of the bottle body 1, so that the two ends of the valve protective sleeve 5 overlap each other and lock and fix it to the bottle body 1, similar to the effect of using a snap fastener.

[0022] The valve protective sleeve 5 is made of soft rubber, such as silicone. The valve protective sleeve 5 is wrapped around the outer wall of the bottle body 1 in a complete circle. The width of the valve protective sleeve 5 should be able to cover the entire finger so that the finger does not come into direct contact with the bottle body 1, for example, at least 1 cm.

[0023] A top vent 31 is provided on the nipple 3. The top vent 31 is normally closed when not subjected to external force. After the liquid in the bottle 1 is sucked, a negative pressure is formed inside the bottle 1. The external air pressure forces open the top vent 31, and together with the air return valve 6, the air pressure inside and outside the bottle 1 is balanced. It also facilitates the return of air in the nipple area and prevents the nipple 3 from being sucked flat due to insufficient air return.

[0024] The nipple 3 is an eccentric nipple, and the top air hole 31 is located away from the nipple tip.

[0025] It also includes an eccentric dust cover 4 with a shape that matches the nipple structure. After the dust cover 4 is placed on the nipple 3, it covers the top air hole 31 and the nipple head together.

[0026] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
