Description

Ventilation device, cover body and container comprising cover body

Technical Field

The invention belongs to the field of daily necessities, and particularly relates to a ventilating device for a container, a cover body containing the ventilating device for ventilating the container and the container with the ventilating function comprising the cover body. Containers using the venting device of the invention are, for example, bottles, cups, jars, boxes and the like, in particular drinking cups for children such as duckbilled cups.

Background

Containers in daily use often have an opening of a body for containing contents closed by a lid. The interior cavity of the container generally forms a relatively closed space when the lid is closed. For example, when the contents of the container are relatively fluid liquids, the contents tend to splash out of the body opening when the lid is opened when the temperature and/or pressure within the cavity is relatively high.

Particularly, in a drinking cup for children such as a duckbill cup, it is known in the art to fill a liquid beverage into a container body having an opening of the drinking cup, and to seal the opening of the container body with a lid body to which a drinking straw such as a straw is attached so as to prevent leakage of the liquid, and to enable the beverage to be sucked from the drinking straw through the drinking straw when drinking. In particular, in such a beverage container, the front end of the drinking straw extends into the liquid beverage, and therefore there are the following problems: when the liquid beverage is warm, the air inside the container is heated, so that the internal pressure rises, and when the liquid beverage is passed through the drinking straw, the liquid beverage is pressed by the air pressure, which easily causes the warm liquid beverage to be ejected from the drinking spout.

In order to solve the above problems and ensure safety and hygiene when using the container, various ventilation devices for the container are provided in the prior art to achieve the function of balancing the pressure difference between the inside and the outside of the container during the process of opening the cover body. These ventilation means are often realized by a cap body sealingly attached to the opening of the container body and a flexible drinking straw. The cover body has a shielding member for partitioning the inside and outside of the container, a valve device for opening and closing the internal flow passage by bending, folding and expanding the drinking straw, and a vent hole opening and closing device for opening and closing a vent hole provided in the shielding member. The air vent opening and closing device is operated in conjunction with the opening and closing of the valve device, and has a valve seat having an air vent and a slider moving therein, the slider being provided with a protruding valve element. Wherein the suction pipe passes through the shielding part and seals the periphery of the suction pipe.

Such a vent device has a great influence on the structure of the cover, particularly, on the shielding member of the cover, and the engagement of the valve element with the vent hole may cause the irregularity of the movement of the cover, increasing the difficulty of opening and closing the cover.

Disclosure of Invention

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a vent device for a container, which has a simple structure and is intended to be manufactured and assembled.

It is another object of the present invention to provide a container top incorporating the venting device that provides ease and convenience of removing all components for cleaning operations.

To this end, the present invention provides an aeration device comprising an air channel and a revolving aeration rod, wherein:

the air channel includes a first end facing an outer circumferential surface of the rotary ventilation bar and a second end facing away from the rotary ventilation bar;

the peripheral surface of the rotary ventilation bar is provided with a concave ventilation groove which is communicated with ambient air in a fluid mode, and the rotary ventilation bar can rotate around a rotary axis extending along the longitudinal direction of the rotary ventilation bar, so that a ventilation state and a sealing state are provided:

in the ventilation state, at least a portion of the ventilation slot of the rotary ventilation bar is in fluid communication with the air passage and, in turn, the air passage is in fluid communication with the ambient air via the ventilation slot;

in the sealed state, the vent slot of the rotary vent lever is not in fluid communication with the air passage and the first end of the air passage is sealed by the outer circumferential surface of the rotary vent lever.

The vent device of the present invention is simple to manufacture and assemble, and can achieve various functions of the vent device through a simple pivoting operation.

According to a preferred embodiment of the air-breather according to the present invention, the first end of the air passage and the outer circumferential surface of the rotary breather lever are separable from each other. Such an arrangement facilitates separation of the air passageway from the rotary air bar, thereby facilitating maintenance and cleaning of the air-moving device.

According to a preferred embodiment of the aeration device of the present invention, the outer circumferential surface of the rotary aeration rod is cylindrical and the axis of rotation of the rotary aeration rod is its central axis. The circular outer peripheral surface facilitates smooth rotation of the rotary ventilation bar, thereby improving the operating comfort of the ventilation device. Furthermore, the circular outer circumferential surface is advantageous for achieving a sealing effect in the sealing state.

According to a preferred embodiment of the ventilation device according to the invention, the ventilation slot extends inside the revolving ventilation bar in the longitudinal direction of the revolving ventilation bar to a longitudinal end face of the revolving ventilation bar. The vent slot thus provided is more fully in contact with the ambient air and provides an air flow path that is long enough to avoid the contents of the container being sprayed into the ambient air via the air passage and vent slot.

According to a preferred embodiment of the ventilation device of the present invention, the ventilation groove extends along a part of the longitudinal direction of the rotary ventilation bar on the outer circumferential surface of the rotary ventilation bar. This arrangement of the vent channel facilitates the formation of a relatively closed air passage, thereby ensuring the hygiene of the container contents and protection from contamination by the external environment.

According to a preferred embodiment of the ventilation device of the present invention, the rotary ventilation bar is a hollow bar including a hollow portion penetrating to a longitudinal end surface of the rotary ventilation bar, and the ventilation groove is recessed from the outer peripheral surface into the hollow portion. The hollow portion provides a relatively large air flow cross section, thereby facilitating air flow through the vent channel including the hollow portion to communicate air inside and outside the container interior.

According to a preferred embodiment of the air vent device according to the invention, the swivel axis of the swivel air bar is arranged substantially perpendicular to the channel axis of the air channel at the first end. The vertically arranged air channels and the revolving ventilation bars facilitate saving of installation space and facilitate construction of relatively tortuous air flow paths.

The present invention also provides a cap for a container, the cap comprising:

a breather device including an air passage and a rotary breather rod that rotates about a rotary axis,

a rotating portion at which the rotary ventilation bar is provided, a concave ventilation groove being provided on an outer circumferential surface of the rotary ventilation bar, the ventilation groove being configured to communicate with ambient air,

a cover body, the air channel disposed at the cover body and extending through at least a portion of the cover body, the air channel including a first end facing the rotary ventilation bar and a second end distal from the rotary ventilation bar,

wherein the rotating portion is rotatable with respect to the cap body between a position providing a ventilation state of the cap body and a position providing a sealing state of the cap body,

in the sealed state, the vent slot of the rotary vent lever is not in fluid communication with the air channel, and the first end of the air channel is enclosed by the outer peripheral surface of the rotary vent lever.

Such a cover allows a simple structure to be realized while providing a ventilation function.

According to a preferred embodiment of the cover of the present invention, the cover main body and the rotating portion of the cover are detachable from each other. Such an arrangement facilitates separation of the air passageway from the rotary air bar, thereby facilitating maintenance and cleaning of the air-moving device.

According to a preferred embodiment of the cover body of the present invention, the rotary ventilation lever is configured to be rotatable with the rotating portion relative to the cover body from a closed position, in which the cover body is in the sealed state, to an open position, in which the cover body is in the ventilation state, via an intermediate position, or from the open position, in which the cover body is in the ventilation state, via an intermediate position. Providing movement of the cap in coordinated cooperation with movement of the venting device may allow for simultaneous operation of the venting device to achieve a corresponding function when the cap is opened to access the contents of the container.

According to a preferred embodiment of the cover of the present invention, the rotary ventilation bar is detachably provided on the rotating portion. The detachable rotary ventilation rod is convenient for maintaining and cleaning the rotary ventilation rod, particularly the ventilation groove of the rotary ventilation rod, thereby being beneficial to prolonging the service life of the ventilation device.

According to a preferred embodiment of the cover of the present invention, the rotary ventilation bar extends from an inner wall of the rotating portion into an inner space enclosed by the rotating portion. The rotary ventilation rod arranged in this way can be better protected by the cover body, so that the adverse effect of the external environment on the ventilation device is avoided.

According to a preferred embodiment of the cap of the present invention, the outer circumferential surface of the rotary ventilation bar is cylindrical and the rotation axis of the rotary ventilation bar is a central axis thereof. The circular outer peripheral surface facilitates smooth rotation of the rotary ventilation bar, thereby improving the operating comfort of the ventilation device. Furthermore, the circular outer circumferential surface is advantageous for achieving a sealing effect in the sealing state.

According to a preferred embodiment of the cover of the present invention, the ventilation groove extends inside the rotary ventilation bar to a longitudinal end surface of the rotary ventilation bar in a longitudinal direction of the rotary ventilation bar. The vent slot thus provided is more fully in contact with the ambient air and provides an air flow path that is long enough to avoid the contents of the container being sprayed into the ambient air via the air passage and vent slot.

According to a preferred embodiment of the cover of the present invention, the ventilation groove extends along a part of the longitudinal direction of the rotary ventilation bar on the outer circumferential surface of the rotary ventilation bar. This arrangement of the vent channel facilitates the formation of a relatively closed air passage, thereby ensuring the hygiene of the container contents and protection from contamination by the external environment.

According to a preferred embodiment of the cover of the present invention, the rotary ventilation bar is a hollow bar including a hollow portion penetrating to a longitudinal end surface of the rotary ventilation bar, and the ventilation groove is recessed from the outer peripheral surface into the hollow portion. The hollow portion provides a relatively large air flow cross section, thereby facilitating air flow through the vent channel including the hollow portion to communicate air inside and outside the container interior.

According to a preferred embodiment of the cover of the present invention, the axis of rotation of the rotary ventilation bar is arranged substantially perpendicular to the channel axis of the air channel at the first end. The vertically arranged air channels and the revolving ventilation bars facilitate saving of installation space and facilitate construction of relatively tortuous air flow paths.

The present invention further provides a container comprising a body comprising an internal cavity for holding contents and a lid according to the above, the lid being engageable with the body of the container and covering an opening of the body, wherein:

when the cover is in the sealed state, the inner cavity of the body is not in fluid communication with the air channel of the cover, such that the inner cavity cannot be in fluid communication with the ambient air through the air channel;

when the cover is in the vent state, the internal cavity of the body is in fluid communication with the air passage of the cover, thereby maintaining the internal cavity in fluid communication with the ambient air through the air passage and the vent slot.

The simple structure of the container realizes the function of ventilation.

According to a preferred embodiment of the container according to the invention, the lid and the body are engaged with each other by a threaded connection. The cover body and the main body are connected through threads, so that the cover body can be conveniently installed, and various structures on the cover body can be conveniently assembled.

According to a preferred embodiment of the container according to the invention, the container comprises a drinking straw extending from outside the inner cavity into the inner cavity.

According to a preferred embodiment of the container according to the invention, the drinking straw extends through the cap and protrudes beyond the cap;

the rotary ventilation bar is configured to be rotatable with the rotating portion relative to the cover body from a closed position in which the cover is in the sealed state to an open position in which the cover is in the ventilation state, via an intermediate position to which the suction pipe is switched with the rotation of the rotating portion between its sealed state and its open state;

when the rotary ventilation rod rotates to the closed position, the suction pipe is blocked by the rotating part of the cover body and is in the sealing state;

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings and described below. While the invention will be described in conjunction with the exemplary embodiments, it will be understood that this description is not intended to limit the invention to those embodiments illustrated. On the contrary, the invention is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention. For convenience in explanation and accurate definition of the technical solutions of the present invention, the terms "upper", "lower", "inner" and "outer" are used to describe features of the exemplary embodiments with reference to the positions of these features as shown in the drawings.

Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

A venting device 100 for a container 200 in accordance with a preferred embodiment of the present invention is shown in fig. 1-5.

In the present context, the term "venting means" is understood to mean a means which enables the gas in one space to be in fluid communication with the gas in the other space so that the gas pressures in the two spaces are equalized. Generally, the source power for the ventilation device to circulate the gas may be the pressure difference of the gas in the different spaces, but active or auxiliary pumping of the gas between the different spaces may also be performed by providing a power source such as a gas pump.

Furthermore, although a particular form of container 200 is shown in the drawings for children, such as a drinking cup (duckbill), the venting device of the present invention can be used with various other types of containers 200, such as drinking cups, hot water bottles, lunch boxes, and the like.

As shown more clearly in fig. 4 and 5, the container 200 includes an interior chamber 210 for holding contents, particularly liquid and gaseous contents that are relatively flowable. The cavity 210 may be a centrally symmetric solid of revolution, or may be other irregular shapes. Preferably, the inner cavity 210 may have an upwardly contracted shape.

Referring next to fig. 1-5, as shown, the container 200 may include a cover 220 and a body 230. The cover 220 is engaged with the main body 230 to cover the opening 231 of the main body 230. Preferably, the cover 220 and the body 230 are engaged with each other by a screw connection, as shown in fig. 4, 5 and 10. Additionally or alternatively, the cover 220 and the body 230 may be connected to each other by other removable means. One or more portions of the cover 220 (e.g., the cover body 221, described below) may also be non-removably coupled to the body 230.

In the embodiment shown in the figures, the cover 220 comprises a cover body 221 and a rotating portion 222 pivotally mounted on the cover body 221, the rotating portion 222 being rotatable with respect to the cover body 221 about an axis perpendicular to the longitudinal axis of the inner cavity 210 (extending in the up-down direction in fig. 1-5), but the rotating portion 222 may also be rotatable with respect to the cover body 221 about other directions, for example about the longitudinal axis of the inner cavity 210. The rotating portion 222 may have different shapes. Preferably, the rotating portion 222 may be a curved shell-like structure, such as a portion of a sphere, as shown in the figures. Generally, the rotating portion 222 is configured to enclose an interior space in which a portion of the cover body 221, for example, and/or one or more components that make up the vent 100 may be housed. The rotating portion 222, for example, an inner wall of the rotating portion 222, may be provided with a structure, such as a rotating shaft 222A and a guide portion 222B (see, for example, fig. 6 to 8), which cooperate with the cover main body 221, so that the rotating portion 222 is rotated with respect to the cover main body 221. The guide portion 222B may include a plurality of concentrically arranged arcuate projections as shown in the figures to cooperate with complementary arcuate slots (not shown) on the cover body 221 to provide a pivot structure. The arc-shaped protruding part can play a certain protection role in the inner space limited by the arc-shaped protruding part. In a preferred embodiment, the cover body 221 and the rotating portion 222 are configured so as to be separable therebetween. Herein, the cover main body 221 and the rotating portion 222 are separable means that they are not integral with each other, but one of the cover main body 221 and the rotating portion 222 can be independently detached with respect to the other.

With continued reference to fig. 4, the air-moving device 100 of the present invention includes an air channel 110 and a rotary air-moving rod 120.

The air channel 110 includes a first end 111 facing the outer circumferential surface 123 of the rotary ventilation bar 120 and a second end 112 facing away from the rotary ventilation bar 120, the second end 112 of the air channel 110 being in fluid communication with the interior cavity 210 of the container 200 for holding contents. It is noted that the air channel 110 is a tube-like structure arranged within a solid structure, and the first end 111 and the second end 112 of the air channel 110 as described herein actually refer to the openings of the air channel 110 on the end face of the structure. The air channel 110 may be straight or may be curved according to actual needs. The diameter of the air channel 110 may be uniform or may be configured to vary along the longitudinal direction of the air channel 110, such as increasing, decreasing, increasing and decreasing, decreasing and increasing, etc., according to actual needs.

The air passage 110 may be provided on the cover body 221. In the preferred embodiment shown in the drawings (see fig. 4, 5 and 6), the cover body 221 includes an inner side facing the inner cavity 210 of the container 200 when it is mounted to the body 230 of the container 200, the cover body 221 may include a projection 223 projecting away from the inner side away from the inner cavity 210 of the container 200, and the air channel 110 may be provided in the projection 223.

As described above, the rotary ventilation bar 120 has the outer peripheral surface 123. The outer peripheral surface 123 defines a longitudinal direction and, thus, a longitudinally extending rotational axis 124 of the rotary vent rod 120, see, e.g., fig. 4 and 9. Preferably and as shown in the figures, the outer peripheral surface 123 of the rotary ventilation bar 120 is cylindrical and the axis of rotation 124 of the rotary ventilation bar 120 is its central axis. However, especially in case the rotary ventilation bars 120 are made of an elastic material, the rotary ventilation bars 120 may also have other shapes of the outer circumferential surface 123, such as oval, elliptical, polygonal, star-shaped, etc. The first end 111 of the air channel 110 may preferably directly engage the outer circumferential surface 123 of the rotary ventilation bar 120, and more preferably have a shape complementary to the outer circumferential surface 123 of the rotary ventilation bar 120.

In the preferred embodiment as shown in fig. 7-9, the rotary vent lever 120 is removably disposed on the container 200, such as on the rotating portion 222 of the cover 220. The means of detachable arrangement include, for example, screwing or snapping.

Preferably, as shown in the figures, the axis of rotation 124 of the rotary ventilation bar 120 is arranged substantially perpendicular to the channel axis 113 of the air channel 110 at the first end 111. Substantially perpendicular means that the two intersect at an angle equal to about 90 degrees, for example 90 ° ± 5 °.

Referring to the first preferred embodiment rotary ventilation bar shown in fig. 6 and the second preferred embodiment rotary ventilation bar shown in fig. 7-9, in both embodiments, the outer circumferential surface 123 of the rotary ventilation bar 120 is provided with a vent groove 121 (see fig. 4) recessed and in fluid communication with the ambient air outside the internal cavity 210.

In both illustrated embodiments, see for example fig. 6 and 7, the ventilation slots 121 may extend within the rotary ventilation bar 120 in the longitudinal direction of the rotary ventilation bar 120 to a longitudinal end face 122 of the rotary ventilation bar 120.

Further preferably, as in the second embodiment shown in fig. 7 to 9, the ventilation groove 121 extends along a part of the longitudinal direction of the rotary ventilation bar 120 on the outer circumferential surface 123 of the rotary ventilation bar 120. In other words, the vent slot 121 may not extend along the entire longitudinal length of the outer circumferential surface 123 of the rotary vent rod 120, but may be recessed only over a section of the outer circumferential surface 123.

As also shown in fig. 7 and 9 and as best shown in fig. 10, the rotary ventilation bar 120 may preferably be a hollow bar comprising a hollow portion 125. The hollow portion 125 penetrates the longitudinal end surface 122 of the rotary ventilation bar 120, and the ventilation groove 121 is recessed from the outer peripheral surface 123 into the hollow portion 125.

The rotary vent rod 120 is capable of rotating about a rotation axis 124 extending longitudinally therealong to provide for transitioning the interior chamber 210 of the container 200 between a vented condition and a sealed condition, as follows:

in the vent state, at least a portion of the vent slot 121 of the rotary vent bar 120 is in fluid communication with the air passage 110 and enables the internal cavity 210 of the container 200 to also be in fluid communication with the external ambient air via the air passage 110 and the vent slot 121.

In the sealed state, the vent slot 121 of the rotary vent rod 120 is not in fluid communication with the air channel 110 and such that the first end 111 of the air channel 110 is sealed by the outer circumferential surface 123 of the rotary vent rod 120. In other words, in the sealed state, the opening of the air passage 110 at the first end 111 is sealed by the outer circumferential surface 123 of the rotary ventilation bar 120, blocking communication with the outside ambient air.

In the exemplary preferred embodiment described above, the rotary ventilation bar 120 is provided on the rotating portion 222, and the air passage 110 is provided on the cover body 221. Thereby, the rotary ventilation bar 120 can be rotated with respect to the air passage 110 in the cover main body 110 in accordance with the rotation of the rotating portion 222 with respect to the cover main body 221. Further preferably, the swiveling vent rod 120 may be disposed on an inner side of the rotating portion 222 to swivel with the rotating portion 222 about the swiveling axis 124. At this time, the vent groove 121 may also open to the inner space covered by the rotating portion 222.

In this preferred embodiment, the rotating portion 222 of the cover 220 and the cover main body 221 may be configured such that:

1) when the rotating portion 222 is completely closed (i.e., the closed position), the breather 100 is in a sealed state (see fig. 11A-11C), at which time the vent groove 121 of the rotary vent lever 120 provided on the rotating portion 222 of the lid body 220 and the air passage 110 provided in the lid body 221, specifically, the projection 223 of the lid body 220 are offset from each other (see, for example, fig. 11B), and the outer circumferential surface 123 of the rotary vent lever 120 covers one end of the air passage 110 to seal the air passage 110;

2) when the rotating portion 222 is rotated by a certain angle to be partially opened and not fully opened (i.e., the intermediate position), the breather device 100 is in a breather state (see fig. 12A to 12C), at which the breather groove 121 of the rotary breather lever 120 provided on the rotating portion 222 of the cover 220 and the air passage 110 provided in the cover main body 221, specifically, the projection 223 of the cover 220 are aligned with each other (for example, see fig. 12B);

and optionally 3) when the rotating portion 222 continues to rotate through a certain angle to be fully opened (i.e., an open position), the breather 100 is again in a sealed state (see fig. 13A-13C), at which time the vent groove 121 of the rotary vent lever 120 provided on the rotating portion 222 of the cover 220 and the air passage 110 provided in the cover body 221, in particular, the projection 223 of the cover 220 are again offset from each other (see, for example, fig. 13B), and the outer circumferential surface 123 of the rotary vent lever 120 once again covers one end of the air passage 110 to seal the air passage 110.

The rotary ventilation bar 120 shown in fig. 11C, 12C and 13C is the rotary ventilation bar 120 of the second embodiment shown in fig. 7-9 discussed above, wherein the ventilation slots 121 extend over a portion of the length of the rotary ventilation bar 120. Of course, the ventilation groove 121 may extend through the entire length of the rotary ventilation bar 120. In fig. 11C, 12C, and 13C, the ventilation groove 121 has a substantially circular cross section in the rotary ventilation bar 120. It will be appreciated that the vent slot may also be configured to have a generally rectangular cross-section. Although the embodiment of the ventilation bar of the present invention is different, the matching relationship between the ventilation slot 121 and the air channel 110 is similar to each other, and the matching relationship can be seen in the operation process shown in fig. 11B, 12B and 13B.

Referring to fig. 13A, there is shown the suction and drinking spout 240 provided on the cap body 221 of the cap 220 of the container 200, which is exposed to the outside in this state as not being shielded by the rotating portion 222. As shown in fig. 11A, 12A and 13A (the drink spout 240 is not exposed because it is shielded by the rotating portion 222 in fig. 11A and 12A), the drink spout 240 may be configured such that:

when the rotating portion 222 of the cover 220 is completely closed (closed position, fig. 11A), the drinking spout 240 (hidden by the rotating portion 222 in fig. 11A) is completely covered by the rotating portion 222 of the cover 220, and at this time, the user cannot access the contents of the container 200 through the drinking spout 240, and particularly, at this time, the drinking spout 240 is in a sealed state;

when the rotating portion 222 is partially opened but not completely opened (middle position, fig. 12A), the drinking spout 240 (hidden by the rotating portion 222 in fig. 12A) is still completely covered by the rotating portion 222 of the cover 220, at this time, the user still cannot get access to the contents of the container 200 through the drinking spout 240, and therefore, at this time, the drinking spout 240 is still in a sealed state;

when the rotating portion 222 is completely opened (an open position, fig. 13A), the rotating portion 222 is completely rotated to one side of the cover 220, so that the drinking spout 240 located at the opposite side of the cover 220 is exposed, and at this time, a user can obtain the contents of the container 200 through the drinking spout 240 (the connection structure between the contents of the container and the drinking spout 240 is not repeated here because it is not the focus of the present invention), and therefore, at this time, the drinking spout 240 is in an open state.

Moreover, in a preferred embodiment, at the drink spout 240, the container 200 may also include other means for facilitating the drawing of the drink. For example, referring back to fig. 1-5, container 200 may also preferably include a drinking straw 241 extending from outside lumen 210 into lumen 210. Suction tube 241 may be in the form of a straw that extends through cap 220 and protrudes beyond cap 220; or may be other conventional suction-assisting devices. The drinking straw 241 may be flexible, for example, to be bent and deformed by an external force to be sealed, and opened by the recovery characteristics of the drinking straw material itself when the external force is removed. Alternatively, the straw 241 may be elastically telescopic to be retracted into the container 200 by an external force to be sealed, and opened by elasticity when the external force is removed. The suction pipe 241 may be opened or closed using a manner common in the art, such as opening and closing the suction pipe 241 by movement of the rotating portion 222 relative to the cap body 221.

Preferably, the suction pipe 241 may be configured to:

when the rotating portion 222 of the cover 220 is completely closed (closed position), the suction pipe 241 is pressed or pressed by the force of the rotating portion 222. The ventilation groove 121 of the rotary ventilation bar 120 is not in fluid communication with the air passage 110, and the first end 111 of the air passage 110 is sealed by the outer circumferential surface 123 of the rotary ventilation bar 120, so that the inner cavity 210 of the container 200 cannot be in communication with the external ambient air through the air passage 110, and at this time, the drinking straw 240 is completely blocked by the rotating portion 222 to be in a sealed state; at this time, the suction pipe 241 is not used from the outside;

when the rotating portion 222 rotates to the middle position, the rotating portion 222 is partially opened but not completely opened, and at least a portion of the suction pipe 241 is pressed or pressed by the force of the rotating portion 222. The rotation of the rotary ventilation bar 120 along with the rotation part 222 leads at least one part of the ventilation groove 121 to be in fluid communication with the air channel 110, so that the inner cavity 210 of the container 200 in fluid communication with the air channel 110 is in fluid communication with the ambient air through the ventilation groove 121, the internal pressure and the external pressure of the inner cavity 210 are balanced, but the suction and drinking pipe 240 is still plugged by the rotation part (222) to be in a sealing state, and at the moment, the suction and drinking pipe 241 cannot be used from the outside;

when the rotating portion 222 is rotated to the open position, the rotating portion 222 is completely rotated to one side of the cover 220 and is separated from the suction pipe 241, and the suction pipe 241 is restored to its in-use state and is in an open state. The rotary ventilation bar 120 is rotated until the ventilation groove 121 is not in fluid communication with the air passage 110 again, and the first end 111 of the air passage 110 is sealed by the outer circumferential surface 123 of the rotary ventilation bar 120, the inner cavity 210 of the container 200 cannot be in communication with the external ambient air through the air passage 110, but the rotation portion 222 releases the drinking straw 240 to place the drinking straw 240 in an open state, at which time the liquid beverage contained in the inner cavity 210 of the container 200 can be drunk.

While the preferred embodiments of the present invention have been described in detail above, it should be understood that aspects of the embodiments can be modified, if necessary, to employ aspects, features and concepts of the various patents, applications and publications to provide yet further embodiments.

These and other changes can be made to the embodiments in light of the above detailed description. In general, in the claims, the terms used should not be construed to be limited to the specific embodiments disclosed in the specification and the claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which such claims are entitled.
