Specifically, as shown in fig. 8 and 11, the lid 20 includes a lid portion 201 and a sliding guide portion 202 connected to the lid portion 201, the lid portion 201 is used to close or open the bung 104, and the first abutting portion 2011a is provided on the lid portion 201. The slide guide 202 has a slide guide surface 202a, and the second contact portion 202b is protruded on the slide guide surface 202 a. The rotating shaft support 40 is provided with a guide groove structure 403, and a groove wall of the guide groove structure 403 comprises a sliding guide wall 403a and two support walls 403b oppositely arranged on two sides of the sliding guide wall 403 a; two shaft ends of the rotating shaft 30 are respectively inserted into the two supporting walls 403b, and the sliding guide part 202 is rotatably connected to the rotating shaft bracket 40 through the rotating shaft 30; the sliding guide surface 202a and the sliding guide wall 403a both use the rotating shaft 30 as the rotating center, and the second limiting portion 403c is recessed on the sliding guide wall 403 a.

More specifically, at least a pair of protruding structures 404 protruding from the upper surface is disposed on the upper surface of the rotating shaft bracket 40, the guiding groove structures 403 are formed by the upper surface being recessed inwards, two opposite side surfaces of the pair of protruding structures 404 and two supporting walls 403b are correspondingly connected, respectively, and two shaft ends of the rotating shaft 30 are respectively inserted into two opposite side surfaces of the pair of protruding structures 404.

When the lid 20 rotates relative to the barrel 10, the sliding guide portion 202 rotates relative to the guiding groove structure 403, the sliding guide surface 202a is adapted to the sliding guide wall 403a and rotates relative to the sliding guide wall 403a, and at this time, the second abutting portion 202b disposed on the sliding guide surface 202a may approach or depart from the second limiting portion 403c disposed on the sliding guide wall 403a along the rotation direction, and further abut against the second limiting portion 403c or depart from the second limiting portion 403 c. When the second abutting portion 202b abuts against the second limiting portion 403c, the lid 20 just closes the bung 104, and when the second abutting portion 202b is away from the second limiting portion 403c in the opposite direction, the lid 20 just starts to rotate from the position closing the bung 104 to the position opening the bung 104. When the first abutting portion 2011a of the flip cap 20 abuts against the first limiting portion 402 of the rotating shaft bracket 40, the flip cap 20 is located at the maximum angle of the opening of the bung 104, and when the first abutting portion 2011a is away from the first limiting portion 402 in the opposite direction, the flip cap 20 starts to rotate from the maximum angle of the opening of the bung 104 to the position of closing the bung 104.

As shown in fig. 8, the lid 201 includes an outer lid 2011 and an inner lid 2012, and the outer lid 2011 and the inner lid 2012 are joined together in the thickness direction of the lid 201 to form the entire lid 201. The side of the outer cap 2011 that is away from the inner cap 2012 is a cap outer side, the side of the inner cap 2012 that is away from the outer cap 2011 is a cap inner side, and the cap outer side and the cap inner side are arranged oppositely along the thickness direction of the cap 201.

The lid portion 201 further has a transition end 203 and a closed end 204 oppositely arranged along the radial direction, and the transition end 203 is rotatably connected to the barrel 10 through the rotation shaft 30. The edge of the outer cover 2011 located at the transition end 203 includes the first contact portion 2011a, which is used to contact with the first position-limiting portion 402 on the rotation shaft support 40 to limit the maximum angle at which the flip cover 20 opens the bung 104. When the cover 201 is located at the maximum angle of opening the bung 104, the cover 201 is substantially perpendicular to the bung 104, or an included angle between the cover 201 and a bracket of the bung 104 is substantially 90 degrees.

In the embodiment of the present invention, along the direction from the transfer end 203 to the closing end 204 of the cover portion 201, the center of gravity of the cover portion 201 is close to the closing end 204 and away from the transfer end 203, so that the cover portion 201 can be automatically turned from the position of opening the bung 104 to the position of closing the bung 104 by the self-weight of the cover portion 201, and therefore, the design of the locking portion at the closing end 204 can be eliminated in the embodiment of the present invention. Under the condition of canceling the locking part, the cover body part 201 can automatically close the bung 104 by virtue of the eccentric force generated by the gravity center shift, so as to achieve a better closing effect.

In this embodiment, the manner of implementing the above gravity center shift design is as follows: when the cover 201 is made of the same material as a whole, the cover inner surface is gradually separated from the cover outer surface in a direction from the switching end 203 to the closing end 204. That is, the thickness of the cover portion 201 gradually increases and the weight of the cover portion 201 gradually increases in the direction from the relay end 203 toward the closing end 204, thereby achieving the center of gravity shift.

Further, in this embodiment, when the cover 201 is located at the position for closing the bung 104, the outer side of the cover is horizontally disposed, and the inner side of the cover is obliquely disposed, accordingly, the bung 104 is obliquely disposed as a whole because the bung 104 and the inner side of the cover are adapted to each other.

Of course, in this embodiment, when the cover 201 is located at the position for closing the bung 104, the outer side of the cover is inclined, and the inner side of the cover is horizontal, accordingly, the bung 104 is horizontal as a whole because the bung 104 and the inner side of the cover are adapted to each other. Compared with the above-mentioned solution, since the outer side surface of the cover body is disposed obliquely, when the cover body 201 is at the position of opening the bung 104, the offset weight of the outer side surface of the cover body can weaken the driving force of the cover body 201 rotating toward the position of closing the bung 104, and therefore, it is preferable that the outer side surface of the cover body is disposed horizontally, and the inner side surface of the cover body is disposed obliquely.

In other embodiments, the same purpose can be achieved by adding a weight structure to the closed end 204 or by using materials with different weights to make the transfer end 203 and the closed end 204 have different weights.

In one embodiment, the bung 104 has a first edge 104a and a second edge 104b opposite to the first edge 104a, the first edge 104a extends to a direction close to or away from the second edge 104b to form a notch 104c, which is understood to be a portion of the opening of the avoiding groove structure 101a that is open to the side of the barrel 10, the barrel 10 is provided with an avoiding groove structure 101a extending from the notch 104c, and the groove area of the avoiding groove structure 101a includes an avoiding area 101 b.

Preferably, the first edge 104a extends to a direction close to the second edge 104b to form a notch 104c, a sealing ring 2013 is disposed on a side of the lid 20 close to the bung 104, the sealing ring 2013 is disposed around the lid 20, in this embodiment, the sealing ring 2013 is particularly disposed around the inner lid and close to the inner side of the inner lid, and the inner lid is exposed from the inner side of the lid, the sealing ring 2013 is engaged with the edge of the bung 104, and the sealing ring 2013 is provided with a U-shaped section 2013a that is positioned and engaged with the notch 104c, so as to peripherally seal the portion of the avoiding groove structure 101 a.
