In other words, the distance from the rotation shaft 32 to the inner side 37A of the second locking portion 37 and the distance to the upper end of the first locking portion 29 are substantially the same (distance R). Further, the outer side 37B of the second latch receiving portion 37 is formed slightly larger than the inner side 37A, and the thickness of the inner side 37A and the outer side 37B increases the strength for locking in the U-shaped lock 28. It is formed as thin as possible as long as it satisfies.

  Further, as shown in FIG. 1, when the U-shaped lock 28 is in the fixed position of the first position X, the front surface 28A of the U-shaped lock 28 (the axis Z of the plug body on the opposite side of the lid hinge portion 12 in the U-shaped lock 28). And the front surface 27B of the lock button 27 (the outer surface along the axis Z of the plug body on the opposite side of the lid hinge portion 12 of the lock button 27), in particular, the front surface 30A on the pushing portion 30 side As shown by the plane S, they are arranged in substantially the same plane. The front face 28A may be disposed slightly outside the front face 27B, particularly the front face 30A.

  On the other hand, when the leading end of the U-shaped lock 28 is in the second position Y that faces downward, the U-shaped lock 28 is in an unlocked state in which the U-shaped lock 28 is not fitted, that is, a gap 38 that opens downward is formed so that the distal end is free Has been. Also in the second position Y, the U-shaped lock 28 is disposed so as to fit on the outer periphery of the lower part of the lock button 27. In addition, when the U-shaped lock 28 is in the second position Y, the U-shaped lock 28 is substantially flush with the surface of the pushing portion 30 at a fixed position in contact with the mounting portion 11 of the U-shaped lock 28. Or it is arranged slightly outside.

  The support portion 39 of the lock rotation shaft 32 has a pair of left and right vertical ribs protruding outward from the outer periphery of the mounting portion 11, and the lock rotation shaft 32 is interposed between the vertical rib-shaped support portions 39. Is provided with a third shaft hole 40 in the horizontal direction, and the lock rotation shaft 32 penetrates the first shaft hole 31 on the back side of the intermediate portion of the lock button 27, and the lock rotation shaft 32 The extension shaft portion 32A is inserted into the second shaft holes 35 at both base ends of the arm portion 34, and both the lock button 27 and the U-shaped lock 28 are pivotally supported by one lock rotation shaft 32. Has been.

  As shown in FIG. 5, the width A in the lateral width direction of both outer surfaces 39A of the pair of left and right support portions 39 is substantially the same as the width between the inner surfaces 34A of the arm portions 34 on both sides. The inner surface 34A of 34 is fitted or loosely fitted to the outer surfaces 39A of the pair of left and right support portions 39, respectively. Further, both ends of the second locking receiving portion 37 are opposed to be connected to the upper end of the rib-shaped support portion 39.

  Further, on both side outer surfaces 39A of the vertical rib-shaped support portion 39, a recess 41 serving as a third locking receiving portion is provided in the vicinity of the third shaft hole 40. The concave portion 41 is connected to the third shaft hole 40 or is slightly separated from the third shaft hole 40, and either or both of the upper and lower sides of the third shaft hole 40 are provided. In the embodiment, they are provided above and below. Instead of the recess 41, a through hole penetrating in the left-right direction may be used. And the convex part 42 which is an inward 3rd latching | locking part is provided in the inner surface which is an opposing surface of the arm part 34 sideways.

  Further, a small convex portion 43 is formed upward on the upper surface of the second locking receiving portion 37, and the small convex portion 43 is formed in a bulging shape instead of a protruding shape.

  Next, the operation of the above configuration will be described. When the beverage is stored, the beverage is first stored in the container main body 2 through the opening of the container main body 2 opened in advance, and then the stopper 3 is attached to the opening and closed. At this time, the U-shaped lock 28 faces downward and is arranged at the second position Y.

  Thereafter, when the lid 9 is closed with the lid hinge portion 12 as the rotation center, the first latch receiving portion 33 is disposed above the support portion 39 provided in the attachment portion 11 and further, The latch receiving portion 37 is disposed on the upper portion of the first latch receiving portion 33. By pressing the cover 9 downward when the cover is closed, the lock button 27 in FIG. 1 rotates counterclockwise around the lock rotation shaft 32 against the spring 27A. This is because the lower surface of the first latch receiving portion 33 and the upper portion of the lock button 27 are tapered surfaces. When the lid 9 is further pressed so as to close the lid 9, the lock button 27 is further rotated so that the first latching portion 29 gets over the first latching receiving portion 33 and reaches the upper portion, and enters the latching state. The lid 9 is fixed to the mounting portion 11.

  Then, in order to fix the lid 9 to the plug body 3 and thus to the container main body 2 side, the pivoting operation portion 36 at the tip of the U-shaped lock 28 is picked and pivoted upward with the lock pivot shaft 32 as the pivot center. . At the beginning of this rotation, as shown in FIG. 6 (A), since the convex portion 42 provided on the arm portion 34 is inserted into the concave portion 41, the distance between the pair of left and right arm portions 34 is a pair of left and right support portions. It is the same as or substantially the same as the width A of the outer surface 39A on both sides of 39.

  Furthermore, as shown in FIG. 6 (B), when the convex portion 42 comes out of the concave portion 41 and contacts the convex portion 42 so as to ride on the side surface of the support portion 39 in the middle of turning the U-shaped lock 28 forward, The arm portion 34 spreads in the axial direction of the lock rotation shaft 32 as it rides up. This expansion is made against the elasticity of the U-shaped lock 28 itself. For this reason, the second shaft hole 35 at the base end of the arm portion 34 slides the extension shaft portion 32A of the lock rotation shaft 32. By moving to the outside, slight gaps are formed between the second shaft hole 35 and the support portion 39 on the left and right, respectively.

  Further, when the U-shaped lock 28 is rotated, and the U-shaped lock 28 is rotated to the first position X facing upward as shown in FIG. By inserting it into the upper concave portion 41, the pair of left and right arm portions 34 returns to the original interval due to the elastic restoring force, and the interval between the pair of left and right arm portions 34 is smaller than the interval in FIG. At this time, the second shaft hole 35 slides on the extension shaft portion 32A. When the U-shaped lock 28 is turned directly upward, the inner surface of the tip end of the U-shaped lock 28 comes into pressure contact with the small protrusion 43 in the second latching receiving portion 37, so that the U-shape is caused by the frictional force. The lock 28 is locked and fixed to the second locking receiving portion 37 to form a double lock of the lid 9.

  On the other hand, in order to release the lock state by the U-shaped lock 28, the rotary operation portion 36 is picked and rotated downward with the lock rotation shaft 32 as the rotation center. As shown in FIG. 6A, the arm portion 34 extends in the axial direction of the lock rotation shaft 32, and the U-shaped lock 28 is fitted into the support portion 39 in the downward state as shown in FIG. Fix together.

  Further, when the pressing portion 30 of the lock button 27 is pressed and the lock button 27 is rotated against the spring 27A, the first locking portion 29 is detached from the first locking receiving portion 33 and the mounting portion 11 is removed. The lock is released further away, and as a result, it is biased by the elastic body 13 and the lid 9 rotates in the opening direction.

As mentioned above, in the said Example, the container main body 2 for drinks, the stopper 3 attached to the opening of this container main body 2, and the opening | mouth provided in the stopper 3 corresponding to Claim 1. 3A, a lid 9 that is pivotally supported by the lid hinge portion 12 to open and close the opening 3A, and a lid hinge portion 12 of the plug body 3 so that it can be rotated 180 degrees on the opposite side. It has a lock button 27 that is a first lock member that is pivotally supported by the moving shaft 32 and holds the lid 9 in a closed state, and is coaxially supported by the lock rotation shaft 32 of the plug body 3. By providing the U-shaped lock 28 which is the second lock member to be held in the closed state, the rotation axis of the lock button 27 and the U-shaped lock 28 is set as the same axis as the lock rotation axis 32. At the unlocked position of the lock 28, the tip of the U-shaped lock 28 does not protrude downward, so that it does not get in the way when holding the container body 2, etc. Since the length of the arm portion 34 of the U-shaped lock 28 can be shortened to reduce the size, the lock rotation operation area is reduced and the operability is simplified. As a result, the operation can be performed with a small moving distance, and the moment operation resistance load weight by reducing the arm can be reduced. Further, since the lock rotation shaft 32 which is a shaft member is shared, the shaft installation space can be reduced by half, the size of the plug body 3 can be reduced, the number of shaft parts can be reduced by half, and the material weight of the plug body 3 can be reduced. Since the assembly process is also halved, product costs can be reduced and productivity can be improved.

Further, the U-shaped lock 28 which is a second locking member corresponding to claim 1, a substantially U-shaped having a pair of left and right arm portions 34, lock rotation axis at both the proximal end of the arm portion 34 32 A first position X that holds the lid 9 in the closed state around the lock rotation axis, and a second position Y that releases the closed state of the lid 9 in the upside down direction. By rotating between the positions, the U-shaped lock 28 is disposed outside the outer periphery of the lock button 27 at a substantially uniform distance in each of the first position X and the second position Y, so that the U-shaped lock When the beverage container receives an impact such as a drop at the release position 28, the U-shaped lock 28 located on the outer periphery of the lock button 27 acts as an interference guide. Direct contact with the floor surface can be avoided, and the U-shaped lock 28 is in the released state. Even so, the lock function of the lock button 27 can be maintained.

Further, in accordance with claim 2 , a convex portion 42 serving as a locking portion is provided inside the arm portion 34 of the U-shaped lock 28, and either the first position X or the second position Y of the U-shaped lock 28 is provided. In one or both of the above, by providing a concave portion 41 that is a latch receiving portion that latches on the convex portion 42 of the arm portion 34 at a position opposite to the plug body 3 or the lid 9, By locking the U-shaped lock 28, the U-shaped lock 28 can be temporarily fixed, and the locked state of the U-shaped lock 28 is not released by vibration or the like.

In addition, the U-shaped lock 28 rotates in correspondence with the third aspect , and in the first position X or the second position Y, the convex portion 42 as the locking portion and the concave portion 41 as the locking receiving portion are locked. When the lock is released, both base ends of the U-shaped lock 28 move elastically outward along the axis of the lock rotation shaft 32, and elastically move inward when locked. Then, since the original position is restored, the turning operation of the U-shaped lock 28 can be performed with a light force.

  As described above, the beverage container according to the present invention has been shown in which one lock rotation shaft is provided at the rotation center of the lock button and the U-shaped lock. Thus, it can be applied to various uses such as providing a lock rotation shaft.
