The upper surface of the upper flange portion among the pair of flange portions 42b is in contact with the lower surface of the top wall portion 10a. That is, the upper surface of the sealing flange 42 is in contact with the lower surface of the top wall portion 10a. One of the pair of flange portions 42 b has a thickness (plate thickness) thinner than that of the seal peripheral wall 41 . The pair of flanges 42b are particularly elastically deformable in the waterproof packing 40, and are easily brought into close contact with the upper opening 2d and the top wall 10a, thereby stably closing them.

The extended flange portion 43 is in the shape of an annular plate centered on the central axis C. As shown in FIG. The extending flange portion 43 protrudes radially inward from the lower end portion of the seal peripheral wall 41 and extends in the circumferential direction. The extended flange portion 43 is disposed directly below the peripheral wall of the cylindrical portion 14 . A gap is provided in the vertical direction between the upper surface of the extending flange portion 43 and the lower end surface of the cylindrical portion 14 . Therefore, when the waterproof seal 40 is assembled, for example, due to manufacturing errors of parts, etc., the extending flange portion 43 is prevented from first touching the lower end surface of the cylinder portion 14, thereby suppressing the close contact between the sealing flange 42 and the top wall portion 10a. A bad situation where the state becomes unstable.

The inner hinge part 51 and the outer hinge part 53 are mutually coaxially arrange|positioned about the hinge center axis|shaft of the 2nd hinge 55 as a common axis.

The locking member 52 is rotatably (swingably) attached to the cap main body 10 via the inner hinge portion 51 . The ring stopper 54 is rotatably attached to the cap main body 10 via the outer hinge 53 . That is, the lock member 52 and the ring stopper 54 are respectively provided on the cap main body 10 .

The inner hinge portion 51 is provided on the front surface of the peripheral wall portion 10 b of the cap main body 10 . The inner hinge portion 51 is disposed on the inner side (that is, on the central axis C side) of the outer hinge portion 53 in the left-right direction. The lock member 52 is supported by this inner hinge portion 51 so as to be freely rotatable in the front-rear direction. The lock member 52 has an upper arm portion 52 a extending upward from the hinge center axis of the second hinge 55 , and a lower arm portion 52 b extending downward from the hinge center axis of the second hinge 55 . At the front end portion of the upper arm portion 52a (the upper end portion of the lock member 52 ), a hook portion (locking portion) 56 is provided so as to protrude toward the rear side. That is, the hook portion 56 is disposed on the lock member 52 , and the hook portion 56 is provided on the cap main body 10 via the lock member 52 and the inner hinge portion 51 . Between the lower arm part 52b and the surrounding wall part 10b, the compression coil spring 57 is provided in the state compressed in the front-rear direction.

The outer hinge portion 53 is provided on the front surface of the peripheral wall portion 10 b of the cap main body 10 . The ring stopper 54 is formed of a curved substantially C-shaped member, and its both ends are supported by the outer hinge 53 so as to be freely rotatable in the vertical direction.

In addition, the cover lock mechanism 50 has: a lock receiving portion (locked portion) 58 for locking the hook portion 56 of the lock member 52; and a stopper receiving portion (locked portion) 59 for the ring stopper 54 Hook up. The lock receiving portion 58 is in the shape of a claw protruding forward from the lower end portion on the front side of the cover body 20 . The stopper receiving part 59 is formed in a substantially semicircular shape suitable for the shape of the inner peripheral part of the ring stopper 54 , and protrudes forward from a position surrounding the lock receiving part 58 on the front surface of the cover 20 . That is, the lock receiving portion 58 and the stopper receiving portion 59 are respectively provided on the cover body 20 .

More specifically, the cap lock mechanism 50 has: a lock receiving portion (locked portion) 58 provided on one of the cap main body 10 and the cap body 20 (the cap body 20 in this embodiment); and a hook portion ( The locking portion) 56 is provided on the other of the cap body 10 and the lid body 20 (the cap body 10 in this embodiment), and is locked to the lock receiving portion 58 from the front side. In addition, the lower surface of the hook portion 56 is engaged with the upper surface of the lock receiving portion 58 so as to be movable in the front-rear direction.

In addition, the cap lock mechanism 50 has a stopper receiving portion (locked portion) 59 provided on one of the cap main body 10 and the cap body 20 (the cap body 20 in this embodiment); and a ring stopper portion. The (locking portion) 54 is provided on the other of the cap body 10 and the lid body 20 (the cap body 10 in this embodiment), and is locked to the stopper receiving portion 59 from the front side. In addition, the inner peripheral portion of the ring stopper 54 is locked to the outer peripheral portion of the stopper receiving portion 59 so as to be movable in the front-rear direction.

In addition, as shown in FIG. 3 and FIG. 5 , in the locked state where the cover body 20 is fixed at the closed position by the cover locking mechanism 50 , the gap dimension L2 in the front-rear direction between the locking member 52 and the cover body 20 is opposed to each other. A dimension L1 in the front-rear direction between the wall portion (contacted portion) 19 and the second bearing portion (contact portion) 23 is small. Specifically, in the present embodiment, the aforementioned gap dimension L2 refers to the front-rear distance between the rear surface of the portion other than the hook portion 56 and the front end of the lock receiving portion 58 provided on the upper arm portion 52 a of the lock member 52 . The size of the gap in the direction (the so-called "play size") L2.

In this lid lock mechanism 50 , when the lid body 20 is in the closed position, the hook portion 56 of the lock member 52 is engaged with the lock receiving portion 58 , whereby the lid body 20 overcomes the rotational force of the first hinge 30 in the opening direction. , into a state fixed relative to the cap main body 10 .

From this state, the user compresses the compression coil spring 57 and presses the lower arm portion 52 b of the lock member 52 rearward, thereby releasing the locked state of the hook portion 56 with respect to the lock receiving portion 58 . Thereby, the lid body 20 biased in the opening direction can be rotated to the open position.

In addition, in the lid lock mechanism 50 , when the lid body 20 is in the closed position, the ring stopper 54 is hooked (locked) to the stopper receiving portion 59 to prevent the lid body 20 from turning in the opening direction. Thus, in the cover lock mechanism 50 , it is possible to prevent the cover 20 from being opened due to unnecessary (unintentional) operation of the lock member 52 or the like.

In the cap unit 1A and the beverage container 100 of the present embodiment described above, when an impact is received from the first hinge 30 side (rear side) due to, for example, dropping, etc., the lid body 20 is displaced to the front side, The second bearing portion (contact portion) 23 of the cover body 20 is in contact with the facing wall portion (contacted portion) 19 of the cap main body 10 . By making the abutting portion 23 abut against the abutted portion 19 to receive the impact, further frontward displacement of the lid body 20 is suppressed. Since the amount of displacement to the front side of the cover body 20 can be suppressed to be small, it is possible to suppress unintentional release of the locked state of the cover body 20 by the cover lock mechanism 50 .

More specifically, since the amount of frontward displacement of the cover body 20 is suppressed to be small, the locked state of the lock receiving portion 58 and the hook portion 56 is maintained favorably. In addition, the locked state between the stopper receiving part 59 and the ring stopper 54 is maintained favorably.

As described above, according to the present embodiment, even if an impact is received by dropping or the like, the locked state of the lid body 20 can be maintained satisfactorily, and the beverage can be prevented from leaking out of the container.

In addition, in this embodiment, when the cover body 20 is in the locked state, the gap dimension L2 provided between the lock member 52 and the cover body 20 in the front-rear direction, that is, the so-called "play size" L2, is set to A dimension L1 in the front-rear direction provided between the contacted part 19 and the contact part 23 is small. Therefore, after the lid body 20 is displaced forward due to an impact caused by dropping or the like, the abutting portion 19 first abuts against the abutting portion 23 , thereby preventing the lid body 20 from exceeding the above-mentioned clearance dimension L2 relative to the lock member 52 in the direction. The front side is displaced and abutted. Since the locked state between the hook portion 56 of the lock member 52 and the lock receiving portion 58 of the cover 20 is maintained favorably, it is possible to more stably prevent the locked state of the cover 20 from being unintentionally released.

In addition, although not particularly shown in the figure, when the gap dimension (play dimension) in the front-rear direction is provided between the ring stopper portion 54 and the lid peripheral wall portion 20 b in the locked state of the lid body 20 , relative to the gap dimension Dimensions, the dimension L1 in the front-rear direction between the opposing wall portion (contacted portion) 19 and the second bearing portion (contact portion) 23 is small, thereby maintaining the stopper portion well received as described above. The locking state of the part 59 and the ring stopper part 54.

In addition, in this embodiment, since the opposing wall part 19 faces the second bearing part 23 from the front side, even if the lid body 20 is in the open state in the open position, it receives a shock from the first hinge 30 side (rear side). In the event of an impact, the impact can also be received by the contact between the opposing wall portion 19 and the second bearing portion 23 . Therefore, the strength in the vicinity of the first hinge 30 of the cap unit 1A is improved, and damage to the first hinge 30 or the like due to dropping or the like can be suppressed.

In addition, in this embodiment, the connecting wall part 18b of the opposing wall part 19 and the 1st bearing part 18 is mutually connected.

In this case, the strength of the first bearing portion 18 is increased by the opposing wall portion 19 , and as a result, damage to the first hinge 30 and the like can be further suppressed. In addition, the increased rigidity of the first bearing portion 18 suppresses the amount of displacement of the cover body 20 toward the front side, and as a result, the effects of the above-mentioned embodiment are more stably exerted.

In addition, in this embodiment, in the longitudinal section shown in FIG. 5 , the rear surface 19 a of the opposing wall portion 19 is in a concave arc shape centered on the hinge central axis A, that is, the rear surface 19 a is in the shape of a hinge around the hinge. A concave surface that expands upward.

In this case, the effect of receiving the second bearing portion 23 by the opposing wall portion 19 is more stable.

In addition, in this embodiment, the pair of the opposing wall part (contacted part) 19 and the second bearing part (contact part) 23 is respectively provided in the left-right direction centering on the center axis C of this cap unit 1A. sides.

In this case, not only the amount of displacement of the cover body 20 to the front side is suppressed to be small, but also the amount of displacement of the cover body 20 so as to rotate (twist in the left-right direction) starting from the first hinge 30 in plan view is suppressed. Even in this case, the impact can be received by a pair of one of the left and right opposing wall portions (contacted portion) 19 abutting against the second bearing portion (contact portion) 23, so that the amount of displacement can be kept small. Therefore, the above-mentioned operation and effect brought about by the present embodiment are more remarkable, and damage to the first hinge 30 and the like due to torsional displacement (deformation) of the cover body 20 can also be suppressed.
