The sliding guide path 42 is formed in the hollow portion 22, and when the inclined release portion 38 is pressed downward by pressing the locking release button 38, the intermediate portion in the front-rear direction is a fulcrum. Thus, the locking member 26 and thus the locking portion 6 can be moved upward. For this reason, a first gap 46 is formed between the upper surface of the locking member 26 and the upper surface of the sliding guide path 42. Further, a second gap 47 is formed between the lower surface of the locking member 26 and the lower surface of the sliding guide path 42. As a result, when the locking release button 38 is pressed, the locking member 26 moves forward, the contact portion between the inclined portion 39 and the inclined receiving portion 40 is the force point, the intermediate portion is the fulcrum, and the locking portion 6 is the action point. When the locking portion 6 is unlocked from the locking receiving portion 28, the locking portion 6 rides on the locking receiving portion 28 at the same time so that the locking can be smoothly released.

  Next, the ring-shaped elastic member 48, which is an elastic member around the hinge that biases the lid 5 in the opening direction with respect to the plug 1, will be described in detail. The bearing 35, which is also referred to as a shaft support portion through which the central portion of the hinge shaft 15 passes, is provided on the rear side of the upper surface of the mounting portion 14 of the plug body 4. The bearing 35 has a cylindrical shape with a center axis (not shown) aligned with the center axis 15Z of the hinge shaft 15, and is erected vertically from the upper surface of the mounting portion 14.

  The ring-shaped elastic member 48 is an elongated string-like shape formed in an annular shape, such as an O-ring or rubber, rubber, elastomer, silicon, etc., and in the embodiment, a ring-shaped elastic member 48 is attached. ing. The ring-shaped elastic member 48 is locked so that the flat side is rectangular when the lid is opened, and the one side part 48A, which is one side, is hooked on the front lower part of the bearing 35. On the other hand, the left and right side portions 48B as the elastic member main body, which is an intermediate portion disposed on the left and right sides of the ring-shaped elastic member 48, are disposed on the left and right side surfaces of the bearing 35, and when the lid is closed and the middle is opened. It is folded around the hinge shaft 15 and is located below the hinge shaft 15 when the cover is fully opened and arranged substantially linearly rearward. The left and right side portions 48B are folded back so as to contact the lower portion of the outer peripheral surface of the hinge shaft 15 from the one side portion 48A side and then contact the rear side of the outer peripheral surface and fold upward. .

  Furthermore, the distal end side of the left and right side portions 48B, that is, the other side portion 48C which is the other side portion is connected so as to be hooked on the rear side of the locking member 26. For this reason, a locking receiving portion 49 for the ring-shaped elastic member 48 is formed at the rear portion of the locking member 26 and is folded upward to form an inverted U shape. The other side portion 48C is located in front of the one side portion 48A when the lid is closed, and is disposed above the central axis 15Z of the hinge shaft 15. For this reason, as shown in FIG. 2, in the closed state where the lock release button 38 is not pressed, the left and right side portions 48B are folded back over the hinge shaft 15 by 180 ° or more. For this reason, the ring-shaped elastic member 48 is in an extended state and acts to pull the locking member 26 backward.

  In this state, as shown in FIGS. 3 and 4, in the closed state where the locking release button 38 is pressed, the inclined receiving portion 40 and eventually the locking member 26 are advanced by the inclined portion 39. As the locking state of the locking portion 6 is released, the ring-shaped elastic member 48 further expands. Since the left and right side portions 48B are folded back over the hinge shaft 15 by 180 ° or more, the ring-like elastic member 48 is in an extended state and acts to pull the locking member 26 backward.

  Further, when the user presses the lock release button 38 to release the lock, the lock portion 6 pops out forward. At that time, when the user who recognizes the release releases the lock release button 38, the lock portion 6 returns to the original position and tries to lock again. Since it is urged | biased upwards, the latching | locking part 6 does not return to the original position, but the cover body 5 will open.

  Further, in order to lock the lid 5 shown in FIGS. 7 and 8 in a fully open state in which the lid 5 is opened more than 90 ° and less than 180 °, a locking receiving projection 50 is formed on the rear portion of the outer peripheral surface of the bearing 35. At the same time, a locking projection 51 is formed in the vicinity of the bearing 35 of the lid 5, and this locking projection 51 is provided so as to be locked to the locking projection 50 in the rotational direction of the lid 5. ing.

  Next, the operation of the above configuration will be described. When the locking portion 6 is locked to the locking receiving portion 28, the lid 5 is maintained in the closed state. In this state, the locking portion 6 continues to be urged backward in accordance with the urging force of the ring-shaped elastic member 48. Further, the liquid passage hole 18 and the air hole 19 are sealed by the water stop member 24.

  On the other hand, when the lid 5 in the closed state is opened, the locking release button 38 is pressed against the coil spring 38S and the urging force of the ring-shaped elastic member in the vertical direction and lowered. When the inclined portion 39 presses the inclined receiving portion 40 forward, the locking portion 6 is detached from the locking receiving portion 28 and the locked state is released. Thereafter, the lid 5 is urged in the opening direction by the ring-shaped elastic member 48 to open 90 °, and further rotates until the locking small protrusion 48 and the locking receiving small protrusion 49 are locked. Is maintained obliquely upward, and the unlocking button 38 is restored. In this state, the container body 2 can be tilted and the stored liquid can be discharged from the liquid passage hole 18.

  When the locking release button 38 is pressed while the lid is open, the locking portion 6 does not move forward. The portion 37 can be forcibly pulled out with a finger or a fingernail.

  Further, after the lid 5 is attached to the container main body 2, the lower end edge is exposed to the outside and does not come into contact with the container main body 2. For this reason, when the lid is closed, it is surely pushed into the locked state again, and when the lid 5 is not opened even when the locking release button 38 is pressed for reasons such as decompression, the lid is put on the edge by placing a hand. Can be opened.

  As described above, in the above embodiment, the plug body 4 is detachably attached to the upper opening 3 of the beverage container body 2, the liquid flow path 18F formed in the plug body 4, and the liquid A spout 12 provided above the flow path 18F and on the front side of the plug body 4 and a lid body that is pivotally supported via a hinge shaft 15 on the rear side of the plug body 4 to open and close the liquid flow path 18F. 5, a water stop member 24 which is provided in the lid 5 and seals the liquid flow path 18F, and is provided between the upper and lower portions of the lid 5 so as to be movable back and forth in the vertical direction and urged upward. It has a stop release button 38 and a locking member 26 which has a locking portion 6 and is provided so as to be able to advance and retreat in a substantially horizontal direction, and locks the lid 5 in the closed state. The lid 5 is attached to the hinge shaft 15. The lid 5 is biased in the opening direction by the elasticity of the ring-shaped elastic member 48, and the ring-shaped elastic member 48 biases the locking member 26 in the locking direction. By pushing the locking release button 38 downward, the locking state of the locking member 26 and the plug body 4 is released, and the lid 5 is opened, so that the ring-shaped elastic member 48 is opened. In addition to the means for urging in the opening direction, the means for urging the locking member 26 in the pulling direction can also be used, so that the number of parts inside the intermediate part of the lid 5 can be reduced and the space for installation thereof can be eliminated. As a result, for example, the lock release button 38 for improving the operability can be enlarged.

  Specifically, a plug body 4 detachably attached to the upper opening 3 of the beverage container body 2, a liquid channel 18F formed in the plug body 4, and an upper portion of the liquid channel 18F.
