Description

Technical Field

[0001] The utility model relates to the technical field of infant products, in particular to an anti-flatulence feeding bottle. Background Art

[0002] When infants and young children are sucking milk from bottles, air can easily enter the bottles and cause bubbles to form in the milk in the bottles. When the milk containing bubbles enters the abdomen, it can cause infants and young children to hiccup, choke, and have colic, which is not conducive to their healthy growth.

[0003] Although some feeding bottles in the prior art have added anti-flatulence structures, such as a one-way valve, which allows external air to enter the inner cavity of the bottle body through the one-way valve to maintain the air pressure balance inside and outside the bottle body, so that the infant can continue to suck milk. At the same time, the air entering from the bottom of the bottle body is kept away from the milk, preventing the air from mixing with the milk to generate bubbles, thereby preventing the milk containing bubbles from being sucked into the infant's abdomen.

[0004] However, the anti-flatulence structure of the existing baby bottle usually needs to be clamped on the outer peripheral wall of the lower part of the bottle body, which makes it inconvenient to disassemble and assemble the anti-flatulence structure; in addition, some baby bottles are provided with an anti-flatulence structure at the bottom of the bottle body, and the anti-flatulence structure is easily contaminated by dust on the table when in contact with the table.

[0048] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0049] The utility model takes the normal placement state of the feeding bottle as a reference, the direction close to the nipple is "up", and the direction away from the nipple is "down".

[0050] Combine the following Figures 1 to 9 , describing an embodiment of the utility model.

[0051] According to an embodiment of the present utility model, on the one hand, an anti-flatulence feeding bottle is provided, such as Figure 1 and Figure 4 As shown, it comprises a bottle body 1, a nipple assembly 2, a bottom cover 3 and an anti-inflation structure 4. The bottle body 1 has openings at both ends; the nipple assembly 2 is detachably connected to the upper opening of the bottle body 1; the bottom cover 3 is detachably connected to the lower opening of the bottle body 1, and an air hole 3021 is provided on the side wall 302 of the bottom cover 3; the anti-inflation structure 4 is arranged between the bottom cover 3 and the lower opening of the bottle body 1, and a one-way valve 401 is provided on the anti-inflation structure 4, the air inlet of the one-way valve 401 is connected to the air hole 3021, and the air outlet of the one-way valve 401 is connected to the inner cavity of the bottle body 1.

[0052] The anti-flatulence milk bottle of this structure has a bottom cover 3 and a detachable connection with the lower end of the bottle body 1. When installing the anti-flatulence structure 4, the anti-flatulence structure 4 is first placed in the bottom cover 3, and then the bottom cover 3 is connected to the lower end of the bottle body 1. The anti-flatulence structure is located between the bottom cover 3 and the lower end opening of the bottle body 1, and the anti-flatulence structure 4 is positioned in the bottom cover 3 by using the lower end surface of the bottle body 1; when the anti-flatulence structure 4 needs to be cleaned, the bottom cover 3 is first removed, and then the anti-flatulence structure 4 is taken out of the bottom cover 3 for washing, and then put back. The bottom cover 3 is easy to disassemble and assemble, and the specific disassembly method is introduced below, which will not be repeated here. After the bottom cover 3 is removed, the anti-flatulence structure 4 can be easily and quickly installed or removed. At the same time, since the anti-flatulence structure 4 is located between the bottom cover 3 and the lower end opening of the bottle body 1, it can effectively prevent it from being contaminated by dust, thereby ensuring the cleanliness and safety of the anti-flatulence structure 4.

[0053] It should be noted that the one-way valve 401 is located on the anti-flatulence structure 4 at the lower part of the bottle body 1. When the infant drinks milk, the bottle is tilted or inverted, the milk is located in the nipple 201 and the upper part of the bottle body 1, and the lower part of the bottle body 1 is air. During the process of the infant sucking the nipple 201, the inner cavity of the bottle body 1 is in a negative pressure state, and the external air pressure is greater than the internal air pressure of the bottle body 1. The external air enters the inner cavity of the bottle body 1 through the one-way valve 401, and the entered air is located at the lower part of the bottle body 1, so as to prevent air from entering the milk to generate bubbles, realize gas-liquid separation, and prevent the milk containing bubbles from being sucked into the abdomen by the infant, so as to prevent the occurrence of hiccups, choking, colic and the like.

[0054] Optionally, in one embodiment, Figure 6 and Figure 7As shown, the anti-inflation structure 4 is arranged in the bottom cover 3, and the bottom cover 3 includes a cover body 301, and a side wall 302 is arranged around the cover body 301. The cover body 301 and the side wall 302 enclose a space for accommodating the anti-inflation structure 4, which plays a good supporting role and can effectively prevent the anti-inflation structure 4 from being contaminated by dust.

[0055] Optionally, in one embodiment, Figure 1 and Figure 4 As shown, both ends of the bottle body 1 are respectively provided with external threads, the nipple assembly 2 and the bottom cover 3 are respectively provided with internal threads matching the external threads, the nipple assembly 2 is threadedly connected to the upper end of the bottle body 1, and the bottom cover 3 is threadedly connected to the lower end of the bottle body 1. By threading the nipple assembly 2 with the upper end of the bottle body 1 and the bottom cover 3 with the lower end of the bottle body 1, the nipple assembly 2 and the bottom cover 3 can be quickly disassembled and assembled, thereby improving the disassembly and assembly efficiency, and it is particularly convenient to disassemble and assemble the anti-inflation structure 4.

[0056] In this embodiment, the nipple assembly 2 includes a nipple 201 and a nipple seat 202. The nipple 201 is installed on the nipple seat 202. The cross-section of the nipple seat 202 is annular. The nipple seat 202 is provided with an internal thread, and the nipple seat 202 is connected to the external thread at the upper end of the bottle body 1.

[0057] like Figures 2 to 4 As shown, the anti-flatulence feeding bottle also includes a feeding bottle cover 5 which is arranged outside the nipple 201 . When the feeding bottle is not in use, the feeding bottle cover 5 is arranged outside the nipple 201 to isolate dust and dirt and ensure the cleanliness of the nipple 201 .

[0058] like Figure 1 and Figure 4 As shown, the bottle body 1 includes a main body and a necking section arranged at the upper and lower ends of the main body, the diameter of the necking section is smaller than the diameter of the main body, and the external thread is arranged on the outer wall surface of the necking section. The nipple seat 202 is threadedly connected with the necking section at the upper end of the main body; the inner wall of the side wall 302 of the bottom cover 3 is provided with an internal thread, and the side wall 302 is threadedly connected with the necking section at the lower end of the main body, so that the outer wall surface of the nipple seat 202 and the outer wall surface of the side wall 302 are basically flush with the outer wall surface of the main body, thereby ensuring the aesthetics of the product.

[0059] like Figure 4 As shown, the main body and the reduced diameter section at its lower end are connected via an inclined portion, which is inclined downward toward the inner side of the bottle body 1, so that milk or cleaning liquid can slide down along the inclined portion, thereby preventing liquids such as milk or cleaning liquid from accumulating in the area between the main body and the reduced diameter section at the lower end, thereby facilitating cleaning of the interior of the bottle body 1.

[0060] The following is a detailed introduction to the installation and removal process of the feeding bottle: during installation, first place the cleaned anti-flatulence structure 4 in the bottom cover 3, screw the bottom cover 3 on the lower end of the bottle body 1, then add water and milk powder from the upper opening of the bottle body 1, screw on the nipple assembly 2, mix the water and milk powder evenly and it can be used by infants and young children. After each use of the feeding bottle, the nipple assembly 2 can be directly unscrewed for washing. After continuous use for 3-5 times (of course, the user can decide the number of uses), when the feeding bottle needs to be thoroughly cleaned, the bottom cover 3 can be removed, the anti-flatulence structure 4 can be taken out for washing, and the bottom cover 3 can be washed together, and then the anti-flatulence structure 4 is installed in the bottom cover 3, and the above-mentioned installation steps are repeated. It can be seen that the feeding bottle of this embodiment is relatively convenient to install and disassemble, and is easy to clean, which can solve the pain points of users who used to be inconvenient to clean and disassemble.

[0061] In other embodiments, the bottom cover 3 may also be connected to the bottle body 1 by a detachable connection method such as a snap connection.

[0062] Alternatively, if Figure 5 , Figure 8 and Fig. 9 As shown, in one embodiment, the anti-inflation structure 4 includes an annular body 402 , and a one-way valve 401 is disposed on the annular body 402 .

[0063] like Figure 4 As shown, the end of the air hole 3021 facing the outside of the side wall 302 is the air inlet of the air hole 3021, and the end of the air hole 3021 facing the inside of the side wall 302 is the air outlet of the air hole 3021. The end of the one-way valve 401 facing the outside of the annular body 402 is the air inlet of the one-way valve 401, and the end of the one-way valve 401 facing the inside of the annular body 402 is the air outlet of the one-way valve 401. The air inlet of the one-way valve 401 is connected with the air outlet of the air hole 3021. The air inlet of the one-way valve 401 is directly connected with the air outlet of the air hole 3021. After the outside air enters the air hole 3021, it can directly enter the inner cavity of the bottle body 1 through the one-way valve 401, so as to shorten the air inlet path and facilitate the air to quickly enter the inner cavity of the bottle body 1.

[0064] In other embodiments, the anti-inflation structure 4 may also be in a flat plate shape, the one-way valve 401 is arranged in the middle area of ​​the anti-inflation structure 4, the air inlet of the one-way valve 401 is arranged below the anti-inflation structure 4, and the air outlet of the one-way valve 401 is located above the anti-inflation structure 4, the bottom surface of the anti-inflation structure 4 and the upper surface of the cover body 301 are spaced apart to form an air inlet cavity, and the air inlet cavity is respectively connected to the air inlet of the one-way valve 401 and the air outlet of the air hole 3021, so that the air inlet of the one-way valve 401 is connected to the air outlet of the air hole 3021.

[0065] In one embodiment, a positioning groove 3022 is provided on one of the inner wall of the side wall 302 and the outer wall of the annular body 402, and a positioning protrusion 403 is provided on the other of the inner wall of the side wall 302 and the outer wall of the annular body 402, and the positioning protrusion 403 is matched with the positioning groove 3022 to prevent the anti-inflation structure 4 from rotating relative to the bottom cover 3. After the anti-inflation structure 4 is installed in the bottom cover 3, the positioning protrusion 403 is matched with the positioning groove 3022, and the air inlet of the one-way valve 401 is aligned with the air hole 3021, and the bottom cover 3 is threadedly connected to the lower end of the bottle body 1. When the bottom cover 3 is tightened on the bottle body 1, the anti-inflation structure 4 can be prevented from rotating relative to the bottom cover 3 due to the positioning effect, so as to prevent the one-way valve 401 from deflecting, and ensure that the outside air enters the inner cavity of the bottle body 1 through the air hole 3021 and the one-way valve 401.

[0066] In a preferred embodiment, Figure 7 and Fig. 9 As shown, the positioning groove 3022 is provided on the inner wall of the side wall 302, and the positioning protrusion 403 is provided on the outer wall of the annular body 402. Figures 6 to 9 As shown, the air hole 3021 corresponds to and is connected with the positioning groove 3022, the one-way valve 401 corresponds to and penetrates the positioning protrusion 403, the air inlet of the one-way valve 401 is located on the positioning protrusion 403, and the air outlet of the one-way valve 401 extends into the annular body 402. When the anti-inflation structure 4 is installed into the bottom cover 3 from top to bottom, the positioning protrusion 403 is snap-fitted into the positioning groove 3022, and the air hole 3021 is connected with the air inlet of the one-way valve 401. The air hole 3021 corresponds to and is connected with the positioning groove 3022, which can shorten the depth of the air hole 3021 and facilitate cleaning of the air hole 3021. The one-way valve 401 corresponds to the positioning protrusion 403 and passes through the positioning protrusion 403. The air inlet of the one-way valve 401 is located on the positioning protrusion 403, and the positioning protrusion 403 is snapped into the positioning groove 3022 so that the air inlet of the one-way valve 401 can better connect with the air hole 3021, making it easier for outside air to enter the inner cavity of the bottle body 1 through the one-way valve 401.

[0067] In other embodiments, the positioning groove 3022 can also be set on the outer wall of the annular body 402, and the positioning protrusion 403 can be set on the inner wall of the side wall 302; the air hole 3021 and the positioning groove 3022 can also be staggered in the circumferential direction of the side wall 302, and accordingly, the one-way valve 401 and the positioning protrusion 403 are staggered in the circumferential direction of the annular body 402.

[0068] like Figure 4 , Figure 5 , Figure 7 and Fig. 9As shown, an annular step surface 3023 is provided on the inner wall of the side wall 302, and an annular flange 404 is provided on the upper end of the annular body 402. The lower surface of the annular flange 404 overlaps the annular step surface 3023, and the lower end surface of the bottle body 1 abuts against the upper surface of the annular flange 404, so as to position the anti-inflation structure 4 between the bottom cover 3 and the lower end opening of the bottle body 1. The annular flange 404 overlaps the annular step surface 3023, which plays a preliminary positioning role for the anti-inflation structure 4, and clamps the anti-inflation structure 4 between the lower end surface of the bottle body 1 and the annular step surface 3023, so that the anti-inflation structure 4 plays a sealing role between the bottle body 1 and the bottom cover 3, so as to prevent liquids such as milk or water from leaking from the gap between the bottle body 1 and the bottom cover 3.

[0069] like Figure 4 As shown, the annular flange 404 is horizontally arranged on the upper surface of the annular body 402, and the width of the annular flange 404 extending toward the outside of the annular body 402 is greater than the wall thickness of the lower end of the bottle body 1, that is, the upper surface area of ​​the annular flange 404 is greater than the area of ​​the lower end surface of the bottle body 1. When the flatness of the annular flange 404 is not good, the sealing between the annular flange 404 and the lower end of the bottle body 1 is easy to fail. In order to solve this problem, as Figure 8 and Fig. 9 As shown, an annular protrusion 4041 is provided on the upper surface of the annular flange 404, and the lower end surface of the bottle body 1 abuts against the annular protrusion 4041. The upper surface area of ​​the annular protrusion 4041 is smaller than the upper surface area of ​​the annular flange 404. Compared with direct contact with the upper surface of the annular flange 404, by setting the annular protrusion 4041 to contact with the lower end surface of the bottle body 1, the contact area between the lower end surface of the bottle body 1 and the annular flange 404 can be reduced, which is more conducive to fitting and sealing. In addition, the annular protrusion 4041 is easy to compress and deform to ensure the sealing effect.

[0070] Optionally, the top surface of the annular protrusion 4041 is flat, and the two side surfaces of the annular protrusion 4041 are arc surfaces inclined toward its top surface, so that the width of the top surface of the annular protrusion 4041 is smaller than the width of its bottom surface, which facilitates the bottle body to squeeze and compress the annular protrusion 4041 and improves the sealing effect.

[0071] Optionally, in one embodiment, the anti-inflation structure 4 is a silicone structural member, and a bottom wall 405 is provided at the lower end of the annular body 402, and the bottom wall 405 is integrally formed with the annular body 402, so that the anti-inflation structure 4 is easy to manufacture and easy to form, and is also easy to install and remove; the bottom wall 405 is integrally formed with the annular body 402, and there is no assembly gap between the two, so the anti-inflation structure 4 is easy to clean. Moreover, the anti-inflation structure 4 is a silicone structural member, which is easy to compress and deform to seal between the bottom cover 3 and the bottle body 1.

[0072] Optionally, the annular protrusion 4041, the annular flange 404, the annular body 402 and the bottom wall 405 are integrally formed. The annular protrusion 4041 is made of silicone, and the lower end surface of the bottle body 1 abuts against the annular protrusion 4041 to achieve isolation and sealing between the inside and outside of the bottle body 1. The cover body 301, the annular body 402 and the inner wall of the bottle body 1 form a receiving cavity for receiving milk.

[0073] like Figure 1 , Figure 4 and Fig. 9 As shown, the annular body 402 is in the shape of a cone with a larger top and a smaller bottom, the inner wall of the side wall 302 is provided with an inclined surface 3024 adapted to the shape of the annular body 402, the outer wall of the annular body 402 is adapted to the inner wall of the side wall 302, and the bottom wall 405 is in contact with the cover body 301. When installing the anti-inflation structure 4, the annular body 402 slides into the bottom of the bottom cover 3 along the inclined surface 3024 of the side wall 302, which plays a certain guiding role and reduces the difficulty of assembly; when disassembling the anti-inflation structure 4, the anti-inflation structure 4 is held in the hand, and the annular body 402 slides upward out of the bottom cover 3 along the inclined surface 3024, so as to facilitate the disassembly of the anti-inflation structure 4.

[0074] like Figure 4 , Figure 5 and Figure 8 As shown, the inner surface of the bottom wall 405 is provided with a handle 406. When disassembling the anti-inflation structure, the user pinches the handle 406 to operate, so as to disassemble and clean the anti-inflation structure 4 or install the anti-inflation structure 4.

[0075] Specifically, in this embodiment, the handle portion 406 includes a flat convex block structure arranged on the inner surface of the bottom wall 405. Optionally, the handle portion 406, the bottom wall 405, and the annular body 402 are integrally formed.

[0076] like Figure 4 and Figure 6 As shown, the lower portion of the side wall 302 is inclined inward to form an inclined surface 3024 that cooperates with the annular body 402 , and the thickness of the side wall 302 at the inclined surface 3024 is greater than the thickness of the side wall 302 at its upper portion to form an annular step surface 3023 at the top of the inclined surface 3024 .

[0077] In other embodiments, the annular body 402 may be in the shape of a straight cylinder, and accordingly, the side wall 302 is vertically arranged.

[0078] like Figure 3 and Figure 4 As shown, the middle area of ​​the bottom surface of the cover body 301 is concave and curved, and correspondingly, the middle area of ​​the bottom surface of the bottom wall 405 is concave and curved, and the bottom surface of the bottom wall 405 contacts the top surface of the cover body 301. The middle area of ​​the cover body 301 is concave and curved, which is conducive to preventing the cover body 301 from deforming.

[0079] like Figure 4 As shown, the one-way valve 401 includes a duckbill valve, the outlet of the duckbill valve is slit-shaped, and the air inlet of the duckbill valve is larger than the outlet. The duckbill valve has a simple structure and a small opening pressure, and is convenient for opening the slit-shaped outlet under negative pressure, so that outside air enters the inner cavity of the bottle body 1. In a normal state, the slit-shaped outlet is closed to ensure that milk does not leak from the duckbill valve.

[0080] In this embodiment, the material of the one-way valve 401 can be the same as that of the annular body 402 , and the one-way valve 401 can be integrally formed with the annular body 402 .

[0081] In other embodiments, the one-way valve 401 can also be a spring-type one-way valve 401, a diaphragm one-way valve 401 or other one-way valve that can achieve a one-way air intake function. In this case, the one-way valve and the annular body 402 are separately arranged, and the outer peripheral wall of the one-way valve is sealed and connected to the annular body 402 to prevent air leakage.

[0082] like Figure 4 As shown, the cross-sectional area of ​​the air inlet passage on the air inlet side of the air hole 3021 can be set to be larger than the cross-sectional area of ​​the air inlet passage on the air outlet side of the air hole 3021, so that external air can enter the air hole 3021. At the same time, the cross-sectional area of ​​the air inlet side passage of the air hole 3021 is large, which is convenient for cleaning the air hole 3021. Optionally, the air hole 3021 is a square hole or a round hole.

[0083] Optionally, in one embodiment, the bottle body 1 is made of glass or plastic, the bottom cover 3 is made of plastic, and the bottom cover 3 is not made of a completely transparent material. When the level of the milk in the bottle body 1 is lower than the top of the side wall 302, the amount of milk in the bottle body 1 cannot be known. To this end, optionally, in one embodiment, a transparent window (not shown) is further provided on the side wall 302 of the anti-flatulence feeding bottle, and scale lines are provided on the transparent window, so that the milk in the feeding bottle can be observed through the transparent window, and the amount of milk can be known through the scale lines.

[0084] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
