Embodiment Construction
[0051] Please refer to the accompanying drawings, the screw cap 2 is rotatably fixed on the external thread 11 of the mouth of the cup body 1 through the internal thread 21 of the lower port; the two are sealed by a sealing ring 5 to prevent water leakage. A step is formed at an appropriate part of the connection between the screw cap 2 and the cup body 1, the step is connected with a hemispherical part, and the hemispherical part and the step are provided with an annular, radially indented annular groove 22. The hemispherical cover 3 corresponding to the hemispherical part is provided with an annular platform 31 on the inner surface corresponding to the annular groove 22 . The cover 3 is positioned by buckling the concave annular groove 22 of the screw cap 2 by the convex annular platform 31 . The hemispherical part of the screw cap 2 is provided with a sunken part, and the sunken part is set through its center; the screw cap 2 is provided with a gap correspondingly; so that ...

Provided is a venting cup cover, comprising a rotary cover (2), a shell (3) and a sliding piece (4). The rotary cover (2) is provided with a hemispherical portion, and the shell (3) and the hemispherical portion are buckled to form a sliding groove for the sliding piece (4) to slide therein; the sliding piece (4) is assembled on the sliding groove; the rotary cover (2) is further provided with a nozzle hole (23), a venting valve hole (24) and a clamping piece (25); the nozzle hole (23) is fixedly connected to a nozzle of a suction tube, or the nozzle hole (23) is fixed to a suction tube component; the nozzle or the suction tube component can be bent along the clamping piece (25) under the action of the sliding piece (4). The venting cup cover is characterized by being further provided with a venting valve fitted over the venting valve hole (24), wherein a rib (42) is provided on the inner side of the sliding piece (4) and corresponds to the venting valve; when the sliding piece (4) completely closes or opens the cup cover, the venting valve closes the venting valve hole (24); during part or all of the course of completely closing and opening the cup cover, the convex piece (42) acts on the venting valve such that the venting valve opens the venting valve hole (24) to form an air channel from inside to outside of the cup cover. The venting cup cover can adjust the air pressure of a container so as to prevent ejection and can be used on a beverage container.
Description
technical field [0001] The invention relates to the technical field of beverage containers, in particular to a breathable cup cover screwed on a cup body. Background technique [0002] At present, beverage containers that use straws to suck liquids have been widely used. In the existing structure, if hot liquid is installed in the container, the air pressure in the container will increase due to heat; when the straw is opened, the hot liquid will flow from the end of the straw squirt. In order to solve this problem, it is necessary to set up a ventilation device on the inner cover; for example, the No. 200610165636.7 Chinese invention patent discloses a cover for a beverage container and a beverage container; The valve body is used for ventilation, and two valve cores are arranged on the slider to ensure that the valve cores are blocked on the air hole of the valve body to seal water when fully open and closed. This structure has relatively high assembly requirements, and ...
