Containers using the venting device of the present invention are, for example, bottles, cups, cans, boxes, etc., especially drinking cups for children such as sippy cups.

The container used in daily life often closes the opening of the main body for containing the contents through the lid. When the lid is closed, the inner cavity of the container generally forms a relatively airtight space. For example, when the content of the container is liquid with strong fluidity, when the temperature and/or pressure in the inner cavity is relatively high, the content is likely to splash out from the opening of the main body when the lid is opened.

Especially for children's drink cups such as sippy cups, it is known in the art to fill the drink cup with a liquid beverage into the container body having an opening, and to use a device such as a straw to prevent leakage. The lid of the similar drinking straw seals the opening of the container main body to prevent liquid from leaking out. When drinking, the beverage can be passed through the drinking straw to inhale the beverage from the drinking straw. Particularly, in this type of beverage container, the front end of the drinking tube extends into the liquid beverage, so there is a problem that when the liquid beverage is warmed, the air inside the container is heated, so that the internal pressure rises, and when the liquid beverage is passed through the suction When the drinking tube is squeezed by air pressure, it is easy to cause the warm liquid beverage to be ejected from the drinking port.

Inside, the cover body 221 may include a protruding portion 223 protruding away from the inner cavity 210 of the container 200 , and the air channel 110 may be disposed in the protruding portion 223 .

As mentioned above, the rotary vent rod 120 has the outer peripheral surface 123 . The outer peripheral surface 123 defines a longitudinal direction and thus defines a longitudinally extending pivot axis 124 of the pivoting ventilation rod 120 , see eg FIGS. 4 and 9 . Preferably and as shown in the drawings, the outer peripheral surface 123 of the rotary aeration rod 120 is cylindrical and the rotation axis 124 of the rotary aeration rod 120 is its central axis. However, especially in the case where the swivel aeration rod 120 is made of an elastic material, the swivel aeration rod 120 may also have an outer peripheral surface 123 of other shapes, such as oval, elliptical, polygonal, star-shaped or the like. The first end 111 of the air channel 110 may preferably directly engage the outer peripheral surface 123 of the rotary aeration rod 120 and more preferably have a shape complementary to the outer peripheral surface 123 of the rotary aeration rod 120 .

In the preferred embodiment shown in FIGS. 7 to 9 , the rotary ventilation rod 120 is detachably disposed on the container 200 , for example, detachably disposed on the rotating portion 222 of the cover 220 . The manner of detachable arrangement includes, for example, screw connection or clip connection.

Preferably, as shown in the figures, the swivel axis 124 of the swivel vent rod 120 is arranged substantially perpendicular to the passage axis 113 of the air passage 110 at the first end 111 . Substantially perpendicular means that the angle between the two is approximately equal to 90 degrees, for example, 90°±5°.

With reference to the rotary ventilation rod of the first preferred embodiment shown in FIG. 6 and the rotary ventilation rod of the second preferred embodiment shown in FIGS. 7 to 9, in these two embodiments, the outer circumference of the rotary ventilation rod 120 Each surface 123 is provided with a recessed ventilation groove 121 (see FIG. 4 ) which is in fluid communication with the ambient air outside the inner cavity 210 .

In the two illustrated embodiments, see for example FIGS. 6 and 7 , the ventilation groove 121 may extend in the rotary ventilation rod 120 along the longitudinal direction of the rotary ventilation rod 120 to the longitudinal end surface 122 of the rotary ventilation rod 120 .

Further preferably, in the second embodiment shown in FIGS. 7 to 9 , the ventilation groove 121 extends along a part of the longitudinal direction of the rotary ventilation rod 120 on the outer peripheral surface 123 of the rotary ventilation rod 120 . In other words, the ventilation groove 121 may not extend along the entire longitudinal length of the outer peripheral surface 123 of the rotary ventilation rod 120 , but is only recessed on a section of the outer peripheral surface 123 .

As also shown in FIGS. 7 and 9 and best shown in FIG. 10 , the swivel vent rod 120 may preferably be a hollow rod including a hollow portion 125 . The above-mentioned hollow portion 125 penetrates to the longitudinal end surface 122 of the rotary ventilation rod 120 , and the ventilation groove 121 is recessed into the hollow portion 125 from the outer peripheral surface 123 .

The rotary venting rod 120 is capable of pivoting around a rotary axis 124 extending longitudinally thereof, thereby providing the inner cavity 210 of the container 200 to switch between a vented state and a sealed state, the two states being as follows:

In the venting state, at least a portion of the vent slot 121 of the rotary vent rod 120 is in fluid communication with the air channel 110 , and enables the inner chamber 210 of the container 200 to also be in fluid communication with the external ambient air via the air channel 110 and the vent slot 121 .

In the sealed state, the vent groove 121 of the rotary vent rod 120 is not in fluid communication with the air channel 110 , and the first end 111 of the air channel 110 is sealed by the outer peripheral surface 123 of the rotary vent rod 120 . In other words, in the sealed state, the opening of the air channel 110 at the first end 111 is sealed by the outer peripheral surface 123 of the rotary ventilation rod 120 , blocking the communication with the external ambient air.

In the exemplary preferred embodiment described above, the rotary ventilation rod 120 is disposed on the rotating portion 222 , and the air channel 110 is disposed on the cover main body 221 . Thus, the rotary ventilation rod 120 can rotate relative to the air channel 110 in the cover body 110 as the rotating portion 222 rotates relative to the cover body 221 . Further preferably, the rotary ventilation rod 120 can be disposed on the inner side of the rotating part 222 to rotate around the rotating axis 124 together with the rotating part 222 . At this time, the ventilation groove 121 may also lead to the inner space covered by the rotating part 222 .

In this preferred embodiment, the rotating portion 222 of the cover 220 and the cover body 221 can be configured such that: 1) When the rotating part 222 is completely closed (i.e. the closed position), the ventilation device 100 is in a sealed state (see Figure 11A to Figure 11C), at this time, the ventilation of the rotary ventilation rod 120 arranged on the rotating part 222 of the cover body 220 The groove 121 and the cover body 221 provided on the cover 220, specifically the air channel 110 in the protrusion 223 are staggered from each other (for example, refer to FIG. One end of the air channel 110 is sealed; 2) When the rotating part 222 turns over a certain angle and is partially opened but not fully opened (ie, the middle position), the ventilation device 100 is in a ventilation state (see FIGS. 12A to 12C ). At this time, the rotation of the cover 220 The ventilation slot 121 of the rotary ventilation rod 120 on the portion 222 is aligned with the air channel 110 provided in the cover body 221 of the cover 220, specifically the protrusion 223 (for example, refer to FIG. 12B );

And optional 3) When the rotating part 222 continues to rotate through a certain angle and is fully opened (ie the open position), the ventilation device 100 is in a sealed state again (see FIGS. 13A to 13C ). The ventilation groove 121 of the rotary ventilation rod 120 on the rotating part 222 and the cover body 221 provided on the cover 220, specifically the air channel 110 in the protrusion 223 are staggered from each other (for example, refer to FIG. 13B ), and the rotation The outer peripheral surface 123 of the vent rod 120 again covers one end of the air passage 110 to seal the air passage 110 .

The rotary aeration rod 120 shown in FIGS. 11C, 12C and 13C is the second embodiment of the rotary aeration rod 120 shown in FIGS. Extended in length. Certainly, the ventilation slot 121 may also extend through the entire length of the rotary ventilation rod 120 . In FIG. 11C , FIG. 12C , FIG. 13C , the ventilation groove 121 has a substantially circular cross-section within the rotary ventilation rod 120 . It will be appreciated that the ventilation slots may also be configured to have a generally rectangular cross-section. Although the specific embodiments of the rotary ventilation rod of the present invention are different, the matching relationship between the ventilation groove 121 and the air channel 110 is similar to each other. The operation process shown.

Referring to FIG. 13A , it shows the drinking opening 240 provided on the cover body 221 of the cover 220 of the container 200 , which is exposed to the outside in this state because it is not blocked by the rotating part 222 . As shown in Fig. 11A, Fig. 12A and Fig. 13A (in Fig. 11A and Fig. 12A, the drinking port 240 is not exposed due to being blocked by the rotating part 222), the drinking port 240 can be configured as:

When the rotating part 222 of the cover body 220 is completely closed (closed position, FIG. 11A), the drinking opening 240 (covered by the rotating part 222 in FIG. 11A) is completely covered by the rotating part 222 of the cover body 220. At this time, the user The contents of the container 200 cannot be obtained through the drinking opening 240, especially when the drinking opening 240 is in a sealed state;

When the rotating part 222 is partially opened but not fully opened (intermediate position, FIG. 12A), the drinking opening 240 (covered by the rotating part 222 in FIG. 12A) is still completely covered by the rotating part 222 of the cover body 220. At this time, The user still cannot obtain the contents of the container 200 through the drinking opening 240, therefore, at this time, the drinking opening 240 is still in a sealed state;

When the rotating part 222 is fully opened (open position, FIG. 13A), the rotating part 222 is completely turned to one side of the cover body 220, so that the drinking port 240 on the opposite side of the cover body 220 is exposed. The drinking port 240 obtains the contents of the container 200 (the connection structure between the contents of the container and the drinking port 240 will not be described in detail here because it is not the focus of the present invention), therefore, at this time, the drinking port 240 is in an open state .

In addition, in a preferred embodiment, at the drinking port 240, the container 200 may also include other devices for drinking. For example, referring back to FIGS. 1 to 5 , the container 200 may also preferably include a drinking tube 241 extending from the outside of the inner cavity 210 into the inner cavity 210 . The drinking tube 241 can be in the form of a straw, extending through the cover body 220 and protruding beyond the cover body 220 ; or it can be other common devices for assisting sucking. The drinking tube 241 may be flexible, for example, so as to be bent and deformed by an external force to be sealed, and to be opened by virtue of the recovery property of the drinking tube material itself when the external force is removed. Alternatively, the drinking tube 241 can also be elastically telescopic, so as to shrink into the interior of the container 200 under the action of an external force to be sealed, and to be opened by virtue of elasticity when the external force is removed. The drinking tube 241 can be opened or closed using common methods in the art, for example, opening and closing the drinking tube 241 by the movement of the rotating part 222 relative to the lid body 221 .

Preferably, the drinking tube 241 can be configured as:

When the rotating part 222 of the cover body 220 is completely closed (closed position), the drinking tube 241 is bent or pressed in by the force of the rotating part 222 . The vent groove 121 of the rotary vent rod 120 is not in fluid communication with the air channel 110, and the first end 111 of the air channel 110 is sealed by the outer peripheral surface 123 of the rotary vent rod 120, so the inner cavity 210 of the container 200 cannot communicate with the outside through the air channel 110.
