Abstract
Description
Technical Field
[0001] This utility model relates to the field of baby bottles, specifically to a venting baby bottle. Background Technology
[0002] When preparing formula in a baby bottle, the hot water inside is in a sealed state and at a high temperature. The steam generated by this steam heats and pressurizes the air inside the bottle, causing the internal air pressure to be higher than the external air pressure. This presents the following problems: First, if the bottle cap is opened directly, the high-pressure gas accumulated inside the bottle is released directly, which can cause the cap to pop up due to the impact, potentially causing discomfort to the user. Second, water can easily spray out from the spout on the cap, forming a jet of water that could choke the drinker.
[0003] Therefore, existing baby bottles often require venting before drinking, such as by pressing around the nipple or by opening the cap and then quickly tightening it. While these two methods are effective, pressing the nipple poses a hygiene risk, and quickly tightening the cap can cause the water temperature inside the bottle to drop. Thus, these two common methods still have certain drawbacks. Utility Model Content
[0004] This utility model provides a venting baby bottle that solves the problems of easy contamination of the bottle spout during the venting process, posing a hygiene risk, and the impact on the water temperature inside the bottle. The main technical solution adopted is as follows:

[0006] Preferably, the first locking block includes a locking base block and a locking crossbar formed on the side of the locking base block and extending circumferentially along the bottle cap assembly; when the first locking block and the second locking block are locked together, the second locking block abuts against the locking base block and can abut against the locking crossbar to constrain the cap from moving away from the bottle cap assembly.
[0007] Preferably, the first locking block is L-shaped, and the rotating structure further includes a stop protrusion located beside the first locking block. The second locking block has a relief groove adapted to the stop protrusion. When the first locking block and the second locking block are in a limiting and tight fit, the stop protrusion is locked in the relief groove to restrict the displacement movement of the second locking block.
[0008] Preferably, the inside of the bottle body is concave at the bottom wall position to form a groove space at the bottom wall position.
[0009] Preferably, the bottle cap assembly includes the bottle mouth and a cap opening sleeve fitted on the bottle mouth; the cap opening sleeve has a locking hole, the bottle mouth has a locking protrusion, the exhaust channel is formed on the locking protrusion and passes through the cap opening sleeve, and when the cap opening sleeve is fitted and connected to the bottle mouth, the locking hole is fitted onto the locking protrusion to restrict the rotational movement of the bottle mouth.
[0010] Preferably, the sealing member is disposed on the inner side of the cover and extends along the axial direction of the cover; the free end of the sealing member forms a sealing head, the protrusion at the inlet position of the exhaust channel forms a recess, and the end of the sealing head is aligned and pressed against the recess to form a surface seal fit.
[0011] Preferably, the bottle cap assembly is connected to the bottle body via at least one quick-release mechanism; the quick-release mechanism includes a toggle member, a limiting block provided on the bottle body, and a sliding groove provided on the bottle cap assembly, wherein the toggle member passes through the sliding groove and slides within the sliding groove, thereby forming a snap-fit engagement with the limiting block through a hook structure to constrain the bottle cap assembly to the bottle body.
[0012] Preferably, the hook structure includes a first barb on the actuating member and a second barb on the limiting block, wherein the first barb and the second barb are adapted to each other to form a snap-fit engagement.
[0013] Preferably, the bottle cap assembly is further provided with a socket for inserting the actuating element, the socket being located beside the slide groove; the actuating element is inserted into the socket to slide into the slide groove; the cross-sectional width of the socket is greater than the cross-sectional width of the slide groove.
[0014] Preferably, the actuating member has a guide protrusion adapted to the slide groove. When the actuating member slides within the slide groove, the guide protrusion is engaged within the slide groove and moves accordingly to constrain the displacement of the actuating member along its length.
[0015] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:
[0016] (1) This utility model provides a venting baby bottle that solves the problems of easy contamination of the bottle nipple and hygiene hazards during the venting process of existing baby bottles, as well as the impact on the internal water temperature. The technical solution of this utility model involves setting a venting channel on the bottle cap assembly. Simply rotating the cap around its axis by a certain angle allows the sealing component to align and block the venting channel, sealing the inside of the bottle. It can also be misaligned to open the venting channel, allowing air to escape from the inside of the bottle to the outside, ensuring that the internal air pressure matches the external air pressure and preventing high-pressure gas buildup inside the bottle. Therefore, when using the baby bottle to vent, the user can quickly achieve this by simply rotating the cap. The entire process does not require touching the bottle nipple, ensuring hygiene, and the internal water temperature remains unaffected and remains at a suitable level.
[0017] (2) In this technical solution, the setting of the rotating stop structure can ensure that the sealing part and the exhaust channel are quickly aligned, so that users can quickly seal the exhaust channel on a daily basis, prevent the internal temperature of the bottle from being affected, and the operation is simple and convenient.
[0018] (3) In this technical solution, the locking base and the locking crossbar in the bottle body and bottle cap assembly are set to abut against each other, which can effectively prevent the bottle cap assembly from directly detaching from the bottle body, and ensure that the sealing component is not easy to fall off by itself when it is aligned and sealed with the exhaust channel, thus ensuring the continuity of the sealing.
[0019] (4) In this technical solution, in order to prevent the first card block and the second card block from disengaging on their own when they are in a limiting and tight fit, the locking setting of the stop protrusion and the relief groove of the second card block can effectively limit the displacement movement of the second card block and prevent the second card block from moving away on its own after it has been engaged with the first card block, so that the product function is stable and secure.
[0020] (5) In this technical solution, the protrusion on the bottle mouth and the hole on the cap opening sleeve can not only enable the cap opening sleeve and the bottle mouth to be quickly installed, but also effectively prevent the bottle mouth from rotating on its own relative to the cap opening sleeve, thus preventing sealing problems between the bottle mouth and the cap opening sleeve in the long process.
[0021] (6) In this technical solution, the protrusion on the bottle mouth and the sealing head at the free end of the sealing component adopt a surface sealing fit, which has better sealing performance and is less likely to cause air leakage and water leakage.
[0022] (7) In this technical solution, the bottom of the bottle has a concave arc forming a groove space. The design of this groove space is mainly used in conjunction with the gravity ball straw. When actually drinking water from the bottle, the bottle is tilted slightly, and the gravity ball in the gravity ball straw will automatically slide down and move into the concave arc space to absorb all the water, without leaving any water residue inside the bottle. It is extremely convenient for daily use and does not easily waste water. Attached Figure Description

[0047] Please see Figures 1 to 10 .
[0048] This embodiment provides a venting baby bottle that solves the problems of easy contamination of the spout 21 during the venting process of existing baby bottles, posing a hygiene hazard, and the water temperature inside the bottle body 1 being affected; see also Figure 1 It includes a bottle body 1 and a cap assembly 2 connected to the bottle body 1, the cap assembly 2 being used to open and close the bottle opening of the bottle body 1; it also mainly includes a sealing cap 3, a venting structure 4, and a screw-locking structure 5; wherein,
[0049] Cap 3, see Figure 1 and Figure 6 The cap is placed on the bottle cap assembly 2 and seals the bottle mouth 21 in the bottle cap assembly 2; the bottle cap assembly 2 includes the bottle mouth 21 and an opening sleeve 22 sleeved on the bottle mouth 21; the opening sleeve 22 is provided with a locking hole 221, the bottle mouth 21 is provided with a locking protrusion 211, and the exhaust channel 42 is formed on the locking protrusion 211 and passes through the opening sleeve 22 (see Figure 4 When the cap sleeve 22 is connected to the bottle mouth 21, the locking hole 221 is fitted onto the locking protrusion 211 to restrict the rotational movement of the bottle mouth 21.
[0050] Exhaust structure 4, see Figures 3 to 5 The exhaust structure 4 includes a sealing member 41 on the cap 3 and the aforementioned exhaust channel 42 on the protrusion 211. The exhaust channel 42 is used to connect the inside of the bottle body 1 with the outside. The cap 3 can rotate around the axis by a certain angle to drive the sealing member 41 to be aligned and sealed or to open the exhaust channel 42.
[0051] Rotation structure 5, see Figure 1 and Figure 2 It includes at least one first locking block 51 disposed on the bottle cap assembly 2 and at least one second locking block 52 disposed inside the cap 3; when the cap 3 rotates, the first locking block 51 and the second locking block 52 are mutually restrained and engaged, so that the cap 3 is positioned in a stopping position, thereby driving the sealing member 41 to be aligned with the exhaust channel 42; in this embodiment, there is only one stopping position, that is, when the first locking block 51 and the second locking block 52 are engaged, the cap 3 is in the stopping position, so as to quickly align and seal the sealing member 41 with the exhaust channel 42.
[0052] In existing technologies, the bottom of the bottle body 1 is designed to be flat, which makes it difficult for the gravity ball in the gravity ball straw (not shown) to suck up the remaining water from the bottom of the bottle body 1, regardless of whether the bottle body 1 is placed flat or tilted at any angle, resulting in water waste. In this embodiment, the bottle body 1 has an inwardly curved design at the bottom wall, forming a groove space 11. The design of this groove space 11 can better cooperate with the use of the gravity ball of the bottle. That is, whether the bottle body 1 is placed normally or tilted, the water will automatically concentrate in the curved groove space 11, and the gravity ball will also automatically slide and move into the curved groove space 11, so that the straw can suck up all the water without leaving water residue inside the bottle body 1. This is extremely convenient for daily use and does not easily waste water.
[0053] In this embodiment, the first card block 51 and the second card block 52 are each provided in threes, and the three are arranged in a circle with equal spacing, so that the cap 3 can be stably installed on the bottle cap and is not easy to loosen or shift.
[0054] In this embodiment, see Figure 1 and Figure 2 The first locking block 51 includes a locking base block 511 and a locking crossbar 512 formed on the side of the locking base block 511 and extending circumferentially along the bottle cap assembly 2. When the first locking block 51 and the second locking block 52 are locked and abutted together, the second locking block 52 abuts against the locking base block 511 and can abut against the locking crossbar 512 to constrain the cap 3 to move away from the bottle cap assembly 2.
[0055] In this embodiment, see Figure 1 and Figure 2 The first locking block 51 is L-shaped. The rotating stop structure 5 also includes a stop protrusion 53 located beside the first locking block 51. The second locking block 52 has a relief groove 521 that matches the stop protrusion 53. When the first locking block 51 and the second locking block 52 are in a limiting and tight fit, the stop protrusion 53 is engaged in the relief groove 521 to restrict the displacement of the second locking block 52. In this embodiment, when the relief groove 521 of the second locking block 52 engages with the stop protrusion 53, the second locking block 52 will not rotate or move circumferentially along the cover 3 on its own unless subjected to a large external force.
[0056] In this embodiment, the stop protrusion 53 is configured as an elastic stop protrusion 53, which can enter the relief groove 521 through elastic deformation; similarly, a certain rotational force is applied to the cover 3, which drives the second locking block 52 to press against the stop protrusion 53 until the stop protrusion 53 elastically deforms, and the relief groove 521 and the stop protrusion 53 will disengage, at which point the cover 3 can be removed from the cover opening sleeve 22.
[0057] In this embodiment, the bottle cap assembly 2 includes a bottle mouth 21 and a cap opening sleeve 22 sleeved on the bottle mouth 21. The cap opening sleeve 22 is provided with a locking hole 221, and the bottle mouth 21 is provided with a locking protrusion 211. The exhaust channel 42 is formed on the locking protrusion 211 and passes through the cap opening sleeve 22. When the cap opening sleeve 22 is sleeved and connected to the bottle mouth 21, the locking hole 221 is sleeved on the locking protrusion 211 to restrict the rotational movement of the bottle mouth 21.
[0058] In this embodiment, see Figure 5 The sealing element 41 is located on the inner side of the cover 3 and extends along the axial direction of the cover 3; see also Figure 4 The free end of the sealing member 41 is formed with a sealing head 411, and the protrusion 211 forms a recess 211a at the inlet position of the exhaust channel 42. The end of the sealing head 411 is aligned and pressed against the inside of the recess 211a to form a surface seal. In this embodiment, the end of the sealing head 411 is arc-shaped, and the recess 211a has a concave arc surface that matches the end of the sealing head 411; in other embodiments, the end of the sealing head 411 may also be V-shaped, and the recess 211a has a concave V-shaped surface that matches the end of the sealing head 411.
[0059] In this embodiment, see Figure 9 The bottle body 1 and the cap assembly 2 are mainly connected by a hinge; see [link / reference] Figure 7 and Figure 10 The bottle cap assembly 2 is connected to the bottle body 1 by at least one quick-release mechanism 6. The quick-release mechanism 6 includes a toggle member 61, a limiting block 62 provided on the bottle body 1, and a sliding groove 63 provided on the bottle cap assembly 2. The toggle member 61 passes through the sliding groove 63 and slides within the sliding groove 63 to form a snap-fit engagement with the limiting block 62 through the hook structure 7, thereby constraining the cap opening sleeve 22 to the bottle body 1.
[0060] In this embodiment, see Figure 10 The hook structure 7 includes a first hook 71 on the actuating member 61 and a second hook 72 on the limiting block 62. The first hook 71 and the second hook 72 are matched to form a snap-fit engagement, thereby restricting the displacement of the actuating member 61 along the length direction and preventing the cap opening sleeve 22 from detaching from the bottle body 1.
[0061] In this embodiment, the bottle cap assembly 2 is also provided with an insertion port 63a for inserting the actuating member 61. The insertion port 63a is located beside the slide groove 63. The actuating member 61 is inserted into the insertion port 63a to enter the slide groove 63 for sliding movement. The cross-sectional width of the insertion port 63a is greater than the cross-sectional width of the slide groove 63. Thus, the insertion port 63a can accommodate the actuating member 61 and its first barb 71. When the actuating member 61 enters the slide groove 63 with a smaller cross-sectional width, the first barb 71 will be restricted from displacement along the length direction.
[0062] In this embodiment, the actuating member 61 is formed with a guide protrusion 611 that is adapted to the slide groove 63. The guide protrusion 611 is located on the outer periphery of the actuating member 61. When the actuating member 61 slides in the slide groove 63, the guide protrusion 611 is engaged in the slide groove 63 and moves accordingly to constrain the displacement of the actuating member 61 along the length direction. In addition, the setting of the guide protrusion 611 can also ensure that the actuating member 61 slides more smoothly and is less prone to jamming, resulting in a better user experience.
[0063] Working principle and usage process of this utility model:
[0064] During installation, please refer to Figure 6 First, hinge the cap opening sleeve 22 to the bottle body 1, and align the latching protrusion 211 on the bottle mouth 21 with the latching hole 221 on the cap opening sleeve 22 to complete the quick-fit installation of the bottle mouth 21 and the cap opening sleeve 22. Then, place the cap opening sleeve 22 on the bottle body 1, and control the sliding of the actuating component 61 to make the first barb 71 and the second barb 72 engage to lock the cap opening sleeve 22 on the bottle body 1 and prevent the cap opening sleeve 22 from moving. Finally, place the cap 3 on the bottle mouth 21 and control the bottle mouth 21 to rotate a certain angle, such that the first latching block 51 and the second latching block 52 mutually limit and abut against each other to form a fit, so that the cap 3 is quickly positioned to the stop position, and the sealing component 41 can quickly align with the exhaust channel 42 to form a seal.
[0065] When filling the bottle with water, firstly, the actuating element 61 is controlled to slide within the groove 63 until it reaches the inlet 63a. Then, the first barb 71 of the actuating element 61 disengages from the second barb 72 of the limiting block 62 on the bottle body 1, allowing the cap opening sleeve 22 to flip open the bottle mouth 21 and fully open the bottle mouth 1, at which point water can be added to the bottle body 1. After adding water, the actuating element 61 is controlled to slide again to completely lock the cap opening sleeve 22 onto the bottle body 1. Finally, when drinking water is needed, the cap 3 is simply rotated at a certain angle, causing the sealing element 41 to be misaligned with the venting channel 42, opening the venting channel 42. The air pressure inside the bottle body 1 is then released to the outside through the venting channel 42, allowing for smooth drinking. Therefore, in this invention, an exhaust channel 42 is provided on the bottle cap assembly 2. By simply rotating the cap 3 around its axis at a certain angle, the sealing member 41 can align and seal the exhaust channel 42, thus sealing the inside of the bottle body 1. It can also be misaligned to open the exhaust channel 42, allowing air to flow between the inside and outside of the bottle body 1, ensuring that the internal and external air pressures are consistent and preventing high-pressure gas buildup inside the bottle body 1. Therefore, when users need to release air from the bottle, a simple rotation of the cap 3 is sufficient for quick and easy operation. The entire process does not require touching the bottle nipple 21, ensuring hygiene, and the water temperature inside the bottle body 1 remains unaffected and at a suitable temperature.
[0066] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
