Exemplary lid covers are described in detail below with reference to fig. 1-3. The cup cover can be used for a flip type cup. The cup cover can cover the body 10 and the flip cover 30 hinged on one side of the body 10. The cap body 10 may include a cap portion 11 and a cup body attachment portion 12 attached to an outer circumference of the cap portion 11 for coupling with and sealing a cup body mouth portion. In addition, the lid 10 is further provided with a drinking port portion 20, and the drinking port portion 20 is communicated with the inner cavity of the lid 10, so that a user can drink water in the cup body through the drinking port portion 20.

The cup attachment portion 12 is formed in a cylindrical shape which is open at both upper and lower sides, and is used for attachment to a cup mouth (not shown). For example, the inner wall of the lower cylinder of the cup body coupling portion 12 may be provided with a screw thread and coupled to the outside of the cup body mouth portion by screw coupling, but the present invention is not limited thereto. The upper cylinder of the cup attachment portion 12 may have a first pivot coupling portion 15 formed thereon for pivotally coupling with the lid 30, and the lid 30 may have a second pivot coupling portion 35 formed thereon, the first pivot coupling portion 15 and the second pivot coupling portion 35 being coupled together by a pivot pin or the like such that the lid 30 can be flipped about the pivot pin to cover the spout portion 20 or open the spout portion 20.

The cover 11 serves to cover and seal an upper portion of the cup attachment portion 12, and is fixedly coupled with the cup attachment portion 12. The cover 11 has a through hole formed therein for providing the spout portion 20. The cover 11 and the cup body connecting part 12 may together form an inner cavity of the cup lid, so that when combined with the cup body mouth part, the cup body mouth part is inserted into the inner cavity to seal the cup body mouth part.

The drinking spout portion 20 extends into the inner cavity of the cup lid via a through hole formed in the cover portion 11 to facilitate drinking of water from the cup body by a user. The drinking portion 20 can be tightly fitted with the cover 11 by means of a groove formed on the outer periphery thereof and form a labyrinth seal.

An air vent 16 is formed on the covering part 11 to communicate the inner cavity of the cup cover with the outside. As an example, the air vent hole 16 is formed between the mouthpiece portion 20 and the first pivot coupling portion 15, and is formed at a position of the cover portion 11 close to the first pivot coupling portion 15.

In addition, according to the utility model discloses a bowl cover is still including setting up the exhaust hole shielding part in lid 10 inboard, and exhaust hole shielding part can set up in the below of exhaust hole 16 to shelter from exhaust hole 16, avoid under the hot water's of packing into the inside hot water condition of cup, high temperature vapor dashes out in the exhaust hole 16. The vent hole blocking portion is spaced from the lower port of the vent hole 16 by a certain gap, so that the vent hole 16 is communicated with the inside of the cup body.

As an example, the vent shield portion may be integrally formed with the mouthpiece portion 20. Specifically, the spout portion 20 may also be formed with a skirt 21 extending to the underside of the vent hole 16 to cover the vent hole 16 from the inside of the lid. The portion of the skirt 21 not covering the vent hole 16 can be tightly attached to the inner wall of the cap 11, so that the spout 20 is not easily detached from the cap 10. The portion of the skirt 21 covering the vent hole 16 may be spaced from the inner wall of the cover 11 to enable the vent hole 16 to communicate the inner cavity of the lid with the outside, in other words, the portion of the skirt 21 below the vent hole 16 may serve as the vent hole barrier. For example, the portion of skirt 21 covering vent hole 16 may form a notch 22, and vent hole 16 may communicate with the interior of the lid through notch 22.

The flip cap 30 may have an inner cavity to cover the spout portion 20 when closed, thereby protecting the spout portion 20 and preventing water leakage. The lid 30 further has a spout seal 33 provided on the top of the lid 30 for sealing the spout 20 to prevent water from leaking from the spout 20 when the lid is closed.

The cup cover according to the embodiment of the utility model also comprises an exhaust hole sealing element 36. The discharge hole sealing member 36 is disposed at the inner side of the lid 30, and the discharge hole sealing member 36 can block the upper port of the discharge hole 16 when the lid 30 is closed. A sealing member receiving chamber is formed at the inner side of the folder 30 such that the discharge hole sealing member 36 is inserted into the sealing member receiving chamber to be combined with the folder 30.

As described above, the flip cover 30 may further include the second pivot connection portion 35 to cooperate with the first pivot connection portion 15 to open and close the flip cover 30. Further, a sealing member accommodating chamber is provided in the lid 30 at a position close to the second pivot coupling portion 35, and a retaining wall 37 is formed around the sealing member accommodating chamber, the retaining wall 37 constituting a sealing member accommodating chamber together with a portion of the lid 30 (wherein a portion of the lid 30 forms a bottom plate of the sealing member accommodating chamber) to accommodate the exhaust hole sealing member 36. When the exhaust hole sealing member 36 is accommodated in the sealing member accommodating chamber, the exhaust hole sealing member 36 may be higher than the retaining wall 37, so that when the lid 30 is closed on the lid body 10, the exhaust hole sealing member 36 may first contact and press the exhaust hole 16 to prevent the retaining wall 37 from first contacting the covering portion 11, so as to block the exhaust hole 16.

The vent seal 36 has a body portion disposed in the seal receiving cavity and a head portion facing the second pivot coupling portion 35 and protruding from the seal receiving cavity to the outside of the lid 30. As an example, an opening through which the head portion may protrude to the outside and may abut on the outer sidewall of the first pivot coupling portion 15 when the folder 30 is fully opened may be formed on the retaining wall 37 of the seal accommodating chamber at a side close to the second pivot coupling portion 35.

Further, the sealing member accommodating chamber is formed in the shape of an open groove, and the vent sealing member 36 can be fitted into the sealing member accommodating chamber through the opening of the sealing member accommodating chamber, with the head of the vent sealing member 36 protruding from the opening of the retaining wall 37 to the outside of the lid. With this arrangement, the vent seal 36 is made less likely to fall out of the seal accommodating chamber. An opening may also be provided in the wall 37 facing the opening through which the user can remove the vent seal 36 for cleaning or replacement.

By way of example, the vent seal 36 may be formed from silicone and may have an interference press fit with the seal receiving cavity to prevent water leakage.

As an example, the vent sealing member 36 may further have a groove 31 formed thereon to save material for forming the vent sealing member 36, while also improving the degree of deformability of the vent sealing member 36.

The head of the vent seal 36 exposed from the opening may abut and be interference-fitted with the outer wall of the first pivot portion 25 to some extent, and be pressed by the first pivot portion 25, thereby increasing the frictional force therebetween and preventing the flip cover 30 from being rotated to cause rebounding.

In addition, a stopper may be formed on the cover 10 to limit the resilient movement of the folder 3 when the folder 30 is in the open position. As an example, the limiting member may be a boss 18 formed on an outer side wall of the first pivot coupling portion 15, the boss 18 may extend from the first pivot coupling portion 15 in a substantially radially outward direction, and the boss 18 may be provided as: when the lid 30 is opened, the head of the discharge hole sealing member 36 is caught at the lower side of the boss 18. Preferably, cup attachment portion 12, which is located below raised portion 18, may also form a recess to receive a portion of flip cap 30, thereby further enabling flip cap 30 to be stabilized in the open position without rebounding. In addition, the position of the convex portion 18 and the depth of the concave portion may be set as desired so that the folder 30 can be opened at different angles.

Hereinafter, a process of opening and closing the folder 30 will be described in detail.

Referring to fig. 3, when the lid 30 is in the closed state, the main body portion of the vent sealing member 36 is tightly pressed against the vent 16 to seal the vent 16. During opening of the lid 30, the head of the vent seal 36 is first pressed by the protrusion 18 and then passes over the protrusion 18 to the underside of the protrusion 18, at which time a portion of the lid 30 may fall into the recess and the head of the vent seal 36 may be caught on the underside of the protrusion 18. Therefore, without an external force being applied to the flip cap 30 to overcome the frictional force between the head of the vent seal 36 and the boss 18 or the cup attachment portion 12, it is difficult for the head of the vent seal 36 to pass over the boss 18 to close the flip cap 30, so that it is possible to prevent an unintended rebound or rotation of the flip cap when the flip cap 30 is fully opened.
