Description

Technical Field

[0001] The present application generally relates to the field of daily necessities, and more particularly to a container with a side air inlet valve. Background Art

[0002] For closed drinking containers such as baby bottles, in order to solve the problem of difficulty in sucking liquid due to the decrease in air pressure inside the container after sucking, an air intake valve device is usually provided between the bottle mouth and the nipple. However, for such an air intake valve, particles in the liquid may block the air intake valve during use, and it is easy to mix air in the milk and cause choking. In addition, the disassembly and cleaning of the air intake valve of such a structure is also relatively troublesome.

[0003] To solve this problem, there is also an air inlet valve installed at the bottom of the container. For example, CN115355343A discloses a return valve and a return container. The return valve includes a valve body and an air path formed along the axis of the valve body; the valve body includes a valve lip and a valve body; the valve lip is located above the valve body, the valve lip is a convex platform surrounded by a diaphragm, and the wall thickness is smaller than the wall thickness of the valve lip; the air path passes through the valve body, and the valve lip is provided with an air gap connected to the air path. The air gap is closed when the container is under non-negative pressure and opened when the container is under negative pressure. However, in this bottom air inlet valve, when warming milk with a milk warmer filled with water, water may enter the container from the one-way valve at the bottom. Utility Model Content

[0004] In order to at least partially solve or improve the problems existing in the prior art, the present application provides a container with a side air inlet valve, which can avoid the problem of choking milk caused by air mixed in the liquid on the one hand, and solve the problem that liquid may enter the inside of the container when warming milk on the other hand.

[0005] According to the present application, a container is provided, the container comprising: a container body for containing liquid, the container body having a side wall, a container opening open to the outside, and a container bottom, wherein a first channel extending in the vertical direction of the side wall is configured in the side wall, and the upper end of the first channel is connected to the outside of the container; a cover portion, the cover portion is configured to close the container opening; and a side air intake valve, the side air intake valve is connected to the first channel through its first opening, preferably connected to the lower end of the first channel, and is configured to have a structure that can be opened unidirectionally to the inside of the container. Preferably, the upper end of the first channel is close to the position of the container opening.

[0006] According to the present application, a first channel is constructed in the side wall of the container body, the upper end of the first channel is connected to the external fluid of the container, and the lower end of the first channel is connected to the side air inlet valve fluid having a one-way valve structure, so that on the one hand, the problem of choking milk due to air mixed in the liquid can be avoided, and on the other hand, the problem that liquid may enter the interior of the container when warming milk is solved, because the upper end of the first channel, that is, the opening for air entry, is located near the container opening. When, for example, water is used to warm milk, the water usually does not exceed the position of the opening, and therefore does not enter the interior of the container.

[0007] According to some embodiments of the present application, the container body is configured with a receiving groove for receiving the side air intake valve at a position corresponding to the first channel along the circumferential direction on the side wall, and the receiving groove extends from the side wall to the interior of the container, preferably horizontally. Preferably, the receiving groove is configured to match the shape of the side air intake valve, so that the side air intake valve can be inserted into the receiving groove from the outside and thereby seal the receiving groove. By configuring the container body and the side air intake valve to be a structure that can be assembled and disassembled by means of a plug or the like, it is facilitated to clean and replace the side air intake valve when it is damaged.

[0008] According to some embodiments of the present application, the side wall has a greater wall thickness at the circumferential position where the first channel is configured relative to other positions on the circumference thereof. To facilitate the formation of the container body and the first channel, the wall thickness near the first channel can be appropriately greater than other positions.

[0009] According to some embodiments of the present application, a flange for mounting the cover is formed at a position of the container body close to the container opening, the flange extends annularly along the circumference of the side wall, a notch is formed at a position of the flange corresponding to the upper end of the first channel, and the notch is connected to the upper end of the first channel. Preferably, in the solution in which the flange and the container body are integrally injection molded, the notch is also directly integrally formed with the first channel, so that the notch itself constitutes the opening of the upper end of the first channel.

[0010] According to some embodiments of the present application, the side vent valve has a second channel connected to the first opening, the second channel has a valve lip at the end close to the interior of the container, the valve lip has a second opening, and the second opening can be opened when the air pressure outside the container is greater than the air pressure inside the container. This design realizes the unidirectional opening structure or the one-way valve function of the side air intake valve with a simple structure. It should be noted that this is only one embodiment of the one-way opening structure of the side air intake valve, and those skilled in the art can think of applying other one-way valve implementation methods commonly used in the art to the solution of the present application.

[0011] According to some embodiments of the present application, the side air intake valve includes a first portion extending toward the interior of the container and a second portion extending toward the first channel and communicating with the first channel, the second portion being connected to the first portion, the first portion being columnar and having an annular second flange in the transition region with the second portion. Preferably, the first portion extends horizontally and the second portion extends vertically. Of course, the side air intake valve is not limited to having the above-mentioned structure, as long as it can communicate with the first channel and open unidirectionally toward the interior of the container.

[0012] According to some embodiments of the present application, the receiving groove has a third opening, the first part of the side air inlet valve can extend from the third opening to the inside of the container, the outer diameter of the second flange is greater than the diameter of the third opening, and the second flange can be snap-fitted to the edge of the third opening. This snap-fit ​​connection method facilitates the installation and removal of the side air inlet valve and can achieve good sealing performance.

[0013] According to some embodiments of the present application, the side air intake valve is configured to be stepped near its first opening. The step-shaped configuration cooperates with the correspondingly shaped recess of the receiving groove to more firmly install the side air intake valve and provide better sealing.

[0014] According to some embodiments of the present application, the valve lip is configured to have two thin-sheet valve flaps extending at an angle to each other, and the two valve flaps together form a V-shape in a cross section. Preferably, the second opening is configured as a cutout at a position where the two valve flaps intersect. Through the above design, the function of a one-way valve is achieved with a simple structure.

[0015] According to some embodiments of the present application, the first channel is formed integrally with the container body by injection molding.

[0016] According to some embodiments of the present application, the side air inlet valve is made of a flexible elastomeric material, which facilitates assembly with the container body on the one hand, and on the other hand, its valve lip can release a path for air to pass through when elastically deformed by force, thereby providing an opening for air to pass through.

[0017] According to some embodiments of the present application, the container body is made of a hard plastic material, so that the container body of a desired shape can be simply manufactured by an injection molding process with the aid of an injection mold of a corresponding shape.

[0018] According to some embodiments of the present application, the cover portion is configured to have a nipple portion or a straw component. Of course, the cover portion may also be configured as a separate cover portion without any accessories.

[0019] The present application is not limited to the above-mentioned embodiments, but different structures can be used to achieve the following advantages provided by the present application, that is, by preferably integrally injection-molding the first channel in the side wall of the container body and the side air inlet valve matched therewith, on the one hand, the problem of choking milk due to air mixed in the liquid can be avoided, and on the other hand, the problem that liquid may enter the interior of the container when warming milk is solved.

[0028] The following is a description of the exemplary embodiments of the present application in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0029] As used herein, the term "including" and its variations mean open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "based at least in part on". The terms "an example embodiment" and "an embodiment" mean "at least one example embodiment".

The orientation or position relationship indicated by directional terms is based on the orientation or position relationship shown in the drawings, which is only for the purpose of facilitating the description of the present application, and does not indicate or imply that the objects referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

[0031] Figure 1 A schematic diagram of an exploded view of a container body and a side air inlet valve of a container 1 according to an embodiment of the present application is shown, wherein the cover of the container is omitted for clarity of description.

[0032] like Figure 1 As shown, the container 1 includes a container body 10 for containing liquid, and the container body is made of a hard plastic material such as polyolefin, especially polypropylene, and is formed by means of an injection molding process, so that the container body of a desired shape can be simply manufactured by means of an injection mold of a corresponding shape. In some embodiments, the hard material constituting the container body can be a hard plastic, such as a hard thermosetting / thermoplastic plastic, so as to facilitate processing and achieve a good containment effect. Figure 1 It can be further seen that the container body 10 is configured to have a thin-walled side wall 11, and the side wall defines a container opening 12 open to the outside. In addition, the container body also has Figure 1 In this embodiment, the container body 1 is configured to be substantially square when viewed in cross section, and the side wall 11 includes two pairs of mutually parallel side wall portions, which together define a substantially square container opening 12. Of course, in other embodiments, the container body and its side wall 11 may be configured to be any other suitable shape, for example, configured to be circular when viewed in cross section and define a circular opening.

[0033] Depend on Figure 1 It can be further seen that the container 1 also includes a side air inlet valve 20, for clear display. Figure 12 shows a schematic diagram of the container body 10 and the side air inlet valve 20 being separated. A receiving groove 13 for receiving the side air inlet valve 20 is provided near the bottom of the side wall 11 of the container body 10. The receiving groove 13 is configured to match the shape of the side air inlet valve 20 so that the side air inlet valve 20 can be inserted into the receiving groove 13 from the outside and thereby seal the receiving groove 13. Figure 1 It can be seen that a flange 14 for mounting a cover to be explained later may be formed at a portion of the container body 10 near the container opening 12 , and a notch 15 for ventilation is formed at a radial position of the flange 14 corresponding to the receiving groove 13 .

[0034] In a preferred embodiment, the side air inlet valve 20 is made of a flexible material, such as a flexible elastomeric material, so that on the one hand, it is easy to assemble with the container body 10, and on the other hand, its valve lip can release a path for air to pass through when it is elastically deformed by force and thus provide an opening for air to pass through. In the meaning of the present application, the flexible elastomeric material can be a material that is softer and elastic than the hard material of the container body, such as a thermoplastic / thermosetting elastic material, silicone, latex, silicone or similar elastic material. The specific structure of the side air inlet valve 20 will be described in detail below.

[0035] Figure 2 FIG. 1 is a schematic diagram showing a container in an assembled state according to an embodiment of the present application. Figure 2 It can be further seen that the container 1 further includes a cover 30, which can be connected to the container body 10 by a connection method known to those skilled in the art, such as a threaded connection or a snap connection. Preferably, when the container 1 is configured as a feeding bottle for infants, the cover 30 further includes a nipple 31. Of course, in other embodiments, the cover 30 may alternatively include a straw component or be configured to not include other accessories. Figure 2 In the embodiment, the side air inlet valve 20 has been installed on the container body 10 and hermetically closes the receiving groove 13 on the container body 10, thereby ensuring the sealing of the container 1 while maintaining the smooth appearance of the surface of the container 1.

[0036] In the prior art bottom air inlet valve solution, since a one-way valve is directly provided at the bottom, when the container is placed in water for heating, there is a disadvantage that water enters the container from the one-way valve of the bottom air inlet valve. Therefore, the present application proposes the following solution, which first refers to Figure 3 Provide explanation.

[0037] Figure 3 FIG. 2 is a cross-sectional view of a container body 10 equipped with a side air intake valve 20 according to an embodiment of the present application. Figure 3It can be seen that the side wall 11 of the container body 10 has a thicker wall thickness on the side where the side air intake valve 20 is installed, and a first channel 16 is formed in the side wall 11 at a circumferential position corresponding to the side air intake valve 20, the first channel is connected with the above-mentioned notch portion 15 at the upper end, and extends vertically downward to the receiving groove 13 or the installed side air intake valve 20. Note that in the scheme without the notch portion 15, the first channel can also be directly connected from the side wall 11 to the outside at the upper end, for example, an opening extending obliquely is opened.

[0038] Continue to refer to Figure 1 It can be seen that the top of the side air inlet valve 20 has a first opening 21, which is connected to the first channel 16, preferably to the lower end of the first channel, in the installed state. Figure 3 As shown, a second channel 22 is formed inside the side air inlet valve 20, and the second channel extends upward to the first opening 21 in the vertical direction, and extends rightward to the valve lip 27 of the side air inlet valve 20 in the horizontal direction. When the air pressure inside the container is lower than the air pressure outside, the valve lip will be opened due to the pressure difference and its own elasticity to release the second opening 24 (see Figure 4 ) or incisions, so that gas can enter the interior of the container from the notch 15 via the first channel 16, the first opening 21, the second channel 22 and the second opening 24 to balance the pressure inside and outside the container.

[0039] Figure 4 FIG. 2 shows a perspective view of a side intake valve 20 according to an embodiment of the present application. Figure 4 It can be seen that the side air inlet valve 20 includes a first portion 23 extending toward the interior of the container, preferably extending horizontally, and a second portion 25 extending toward the first channel 16, preferably extending vertically and communicating with the first channel 16. The first portion 23 is overall structured in a columnar shape, preferably a cylindrical shape, and an annular second flange 26 is constructed near the transition area between the first portion 23 and the second portion. Figure 5 It can be seen that the outer diameter of the second flange 26 is larger than the diameter of the third opening 17 of the receiving groove 13 for the first part 20 of the side intake valve 20 to pass therethrough, and the second flange can be inserted into the third opening 17 by its elasticity and snapped at the edge of the third opening.

[0040] Depend on Figure 4 It can be further seen that in this embodiment, the side air intake valve 20 is configured in a stepped shape near its first opening 21. The cooperation between the stepped structure and the correspondingly shaped recess of the receiving groove 13 can more firmly install the side air intake valve and provide better sealing. In the stepped structure, the second channel 22 first extends downward at an angle and then extends vertically downward. Of course, the stepped structure may not be provided, so that the second channel 22 extends vertically downward directly from the first opening 21. In addition, Figure 4 It can be seen that the second opening 24 or the position of the cutout is in a closed state in the figure when there is no pressure difference, and will be opened by the airflow to allow air to pass through when the air pressure outside the container is high.

[0041] Figure 5 FIG. 2 is a schematic diagram showing a container body 10 according to an embodiment of the present application without a side air inlet valve 20 installed. Figure 5 It can be seen that the flange 14 is provided with a notch 15 at a position corresponding to the receiving groove 13 in the circumferential direction, and the notch 15 is simultaneously in fluid communication with the upper portion of the first channel 16 in the side wall 11, so that gas can enter the first channel 16 from the notch 15. In a preferred embodiment, the flange 14 is integrally formed with the container body 10 or the side wall 11, for example, integrally injection molded, so that the notch 15 and the first channel 16 are processed simultaneously in this process.

[0042] Note that the solution according to the present application is applicable to a solution in which the cross-section of the container is square as shown in the figure, because in this case it is relatively easy to process the side air intake valve 20 that is adapted to the shape of the receiving groove 13, but of course the solution of the present application can also be applied to common containers with a circular cross-section.

[0043] Figure 6 FIG. 2 shows a partial cross-sectional view of a state where the side air intake valve 20 is installed on the container 1 according to an embodiment of the present application. Figure 6 It can be seen that the schematic structure of the valve lip 27 of the side air intake valve 20 is shown. In this embodiment, the valve lip 27 of the side air intake valve 20 is constructed to have two thin-walled valve flaps extending at an angle to each other. The two valve flaps together form a V-shaped shape in the cross section. At the vertex of the V-shaped shape, that is, at the position where the two valve flaps intersect, there is a cut or the second opening 24, for example, cut by a knife. Since the side air intake valve 20 is made of elastic material, when the air pressure inside and outside the container 1 is balanced, the second opening 24 is squeezed against each other due to the elasticity of the material and is therefore closed. When the air pressure outside the container 1 is greater than the air pressure inside the container 1 and exceeds a certain threshold, the second opening 24 is opened by the air flow, so that the external air can enter the container 1 to balance the air pressure. Note that only one implementation of the one-way valve structure of the side air intake valve 20 is shown here by way of example. Of course, those skilled in the art can also think of applying other common one-way valve structures to the side air intake valve 20 of the present application.

[0044] Figure 7 FIG. 2 shows a schematic cross-sectional view of a side air intake valve 20 according to the present application when it is installed on a container body 10. Figure 7It can be seen that the side air intake valve 20 is inserted into the receiving groove 13 of the container body 10 from the outside in a plug-like manner, and its first part 23 extends from the receiving groove 13 to the inside of the container, thereby placing the above-mentioned valve lip 27 in the interior of the container, while its second part 25 is tightly accommodated in the receiving groove 13.

[0045] The working principle of the side air inlet valve 20 of the container 1 according to the present application is briefly described below. Figure 3 In the installed state, the side air inlet valve 20 is tightly fitted in the receiving groove 13 of the container body 10, and its first part 23 extends from the receiving groove 13 into the interior of the container 1. At this time, air can flow from the notch 15 near the container opening 12 through the first channel 16 in the side wall 11 and the second channel 22 of the side air inlet valve 20 to the vicinity of the valve lip 27. In the state of pressure balance, the two valve flaps of the valve lip 27 elastically squeeze each other to close the second opening 24, and air cannot enter the interior of the container 1. When the pressure inside the container 1 is lower than the external pressure, for example, in the case of sucking, the pressure difference between the inside and outside of the container 1, that is, the pressure caused by the pressure difference between the second channel 22 of the side air inlet valve 20 and the inside of the container 1, will open the second opening 24, so that the air outside the container 1 can enter the interior of the container 1 and reach the pressure balance state again. At this time, the valve lip 27 will restore its original shape due to its elasticity and re-close the second opening 24, so that air cannot continue to pass.

It should be understood by those skilled in the art that more variations and modifications can be made according to the teachings of the present disclosure, and these variations and modifications all fall within the protection scope of the present disclosure.
