Further, a laterally concave portion 81 that is long in the left-right direction is provided on the distal end side of the arm outer surface portion 71G, and a fitting portion 82 that fits into the concave portion 81 is provided in the arm inner surface portion 71N. The fitting portion 82 serves as a lock operation portion.

  A substantially U-shaped fitting protrusion 84 is provided on one of the mating surfaces 83G and 83N of the outer surface member 20G and the inner surface member 20N, and a fitting groove 85 into which the fitting protrusion 84 is fitted is provided on the other. In this example, the fitting protrusion 84 is provided on the mating surface 83G of the outer member 20G, and the fitting groove 85 is provided on the mating surface 83N of the inner member 20N. The fitting protrusion 84 and the fitting groove 85 are continuously formed across the left and right arm portions 71 and 71 and the connecting portion 72.

  Further, on the base end side of the mating surfaces 83G and 83N of the arm outer surface portion 71G and the arm inner surface portion 71N, a split shaft hole 731, a semicircular fitting recess 86 and a protrusion 87 are formed on one of them. A split shaft hole 731, a semicircular fitting projection 88 and a hole 89 are formed on the other side of this, and in this example, a split shaft hole 731 and a semicircular shape are formed on the base end side of the mating surface 83 G of the arm outer surface portion 71 G. Are formed, and a split shaft hole 731 and a semicircular fitting convex portion 88 are formed in the arm inner surface portion 71N. Further, the fitting convex portion 88 is formed with an outer shaft hole 732 that constitutes a part of the second shaft hole 73, and the divided shaft hole 731 is formed on the outer side in the left-right direction at the base end of the arm portion 71. Thus, the fitting concave portion 86 and the fitting convex portion 88 are provided on the inner side in the left-right direction, and the protrusion 87 and the hole 89 are provided on the proximal end side with respect to the split shaft hole 731.

  Then, in a state where the outer surface member 20G and the inner surface member 20N are integrated, an inner shaft hole 733 continuous to the outer shaft hole 732 is formed by the divided shaft holes 731 and 731 of the outer surface member 20G and the inner surface member 20N. The second shaft hole 73 is constituted by the hole 732 and the inner shaft hole 733.

  Locking portions 91 and 91 are provided inside the base end side of the U-shaped lock 20. In this example, the protruding locking portion 91 is provided on the base end side from the position of the split shaft hole 731 of the arm outer surface portion 71G. The locking portion 91 is the same as the second shaft hole 73 in the left-right direction. The tip is formed on the side, and the tip is formed in a spherical shape. In addition, the division | segmentation latching | locking part 91A and 91A which divided | segmented the latching | locking part 91 are formed in the said outer surface member 20G and the inner surface member 20N, respectively, and the outer surface member 20G and the inner surface member 20N are integrated, and outer surface member 20G and inner surface member A locking portion 91 composed of 20N split locking portions 91A and 91A is formed.

  Further, as shown in FIG. 11, corresponding to the locking portion 91, a locking receiving portion 92 corresponding to the first position is provided on the outer side surface of the mounting wall portion 61 in the left-right direction. Lock receiving portions 92A corresponding to the positions are provided, and these lock receiving portions 92, 92A are formed of circular recesses to which the lock portions 91 can be engaged and disengaged, and are positioned at an equal distance from the mounting hole 61H. The locking portion 91 is locked to the upper locking receiving portion 92 when the U-shaped lock 20 is in the first position, and the locking portion 91 is positioned at the lower position when the U-shaped lock 20 is in the second position. Locks to the stopper 92A.

  In this case, between the latch receiving portions 92 and 92A, the latch portion 91 slides on the outer side surface in the left-right direction of the mounting wall portion 61. At this time, the base end of the arm portion 71 is slightly opened by elastic deformation. When the locking portion 91 slides and the locking portion 91 is locked to the locking receiving portions 92 and 92A, the base end of the arm portion 71 returns to the original position. A click feeling is obtained when locking to the stopper 92. As shown in FIGS. 2 and 16, the lid 12 is formed with a substantially inverted U-shaped flat surface 12G on the top, bottom, left and right of the locking receiving portion 64, and the inner surface member 20N is flat at the first position. The outer surface 93 is substantially along the flat surface 12G. In this case, a gap may be provided.

  Further, the U-shaped lock 20 is formed by integrating the outer surface member 20G and the inner surface member 20N by two-color molding, or after molding one of the outer surface member 20G and the inner surface member 20N first, the other is molded. Is formed by insert molding that integrates the two. By molding in this way, the color of the resin material is changed so that the outer surface member 20G and the inner surface member 20N have different colors. In this example, the outer surface member 20G has a lighter color than the inner surface member 20N.

  In addition, when performing insert molding, it is preferable to shape | mold the inner surface member 20N which becomes the surface side first in the locked state of a 1st position. That is, if the inner surface member 20N is formed first and the outer surface member 20G is formed later, the inner surface member 20N side can be pushed out when the mold is opened to release the mold. The pushing mechanism such as the pushing pin does not remain behind. Similarly, since the outer shaft hole 732 and the like are formed by using a slide mold that intersects with the opening / closing direction of the mold, it is advantageous in terms of molding to be provided on the inner surface member 20N that is a primary side molded product.

  When the outer surface member 20G and the inner surface member 20N are integrally formed, a fitting portion 82 of a color different from that of the connected outer surface portion 72G appears at the tip of the connected outer surface portion 72G of the outer surface member 20G. In the two-color molding and the insert molding, the outer surface member 20G and the inner surface member 20N that are formed first are the primary-side molded products, and those that are formed later are the secondary-side molded products.

  Next, the operation of the above configuration will be described. When assembling the lock button 19 of the lock mechanism 17, the guide rail 51 of the button assembly member 27 is aligned with the groove 53 of the button body member 26, the guide rail 51 is slid into the groove 53, and the lock receiving portion is engaged with the lock portion 54. By locking 52, the button body member 26 and the button assembly member 27 can be simply temporarily assembled and integrated to assemble the lock button 19. In this state, the arm portion 41 and the holding portion 42 of the button assembly member 27 are assembled so as to sandwich the button main body member 26 from the front and rear, and the vertical portions 41T, 41T of the arm portion 41 are the wide portions 30, Located outside of 30.

  Accordingly, even when only the outer surface of the button assembly member 27 is pressed when the lock button 19 is operated, the button main body member 26 rotates and the engagement between the engagement piece 63 and the engagement portion 29 is released. 26 unlocking operations can be performed reliably. In addition, by assembling the button body member 26 and the button assembly member 27 from the direction crossing the thickness direction in this way, it is simpler and more reliable than the case of assembling from the conventional thickness direction (inside / outside direction). Assembly can be performed.

  Further, in this case, the button body member 26 and the button assembly member 27 can be assembled in a state where the button body member 26 and the button assembly member 27 are correctly positioned by the engagement between the longitudinal groove 53 and the guide rail 51. Further, the upper ends of the vertical portions 41T and 41T of the arm portion 41 are free ends, and when the guide rail 51 is inserted into the groove 53, it can be elastically deformed so that the space between the upper ends of the vertical portions 41T and 41T is widened. The guide portions 51A and 51A at the ends of the guide rail 51 are formed obliquely so that the distance between the guide portions 51A and 51A is widened toward the distal end side, and therefore can be inserted smoothly.

  Further, the lock button 19 temporarily assembled by the engagement of the engagement portion 54 and the engagement receiving portion 52 is locked in the first shaft hole 33 of the button body member 26 and the bearing groove 46 of the button assembly member 27. Since the rotation shaft 62 is inserted and the lock rotation shaft 62 is attached to the mounting wall portions 61, 61 of the plug body 10, the lock rotation shaft 62 can be rotated. The button assembly member 27 is integrated.

  Further, the lock button 19 is configured so that the rotation range of the lock button 19 is restricted by the contact portion 45T of the button assembly member 27 being in contact with the outer surface of the cylindrical portion 8 (see FIG. 2). There is no need to provide ribs on the inner surface of the main body member 26, and sink marks on the outer surface of the button main body member 26 do not occur.

  The button assembly member 27 has a different color from the button main body member 26, and the arm portion 41 appears in a different color on the left and right of the main body outer surface portion 28. The operability of the lock button 19 is improved, and the arm portion 41 is visually recognized in a substantially U shape, whereby an unprecedented design property can be obtained.

  Next, when the beverage is stored, the beverage is first stored in the container main body 2 from 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 20 is disposed in the second position so as to face downward.

  Thereafter, when the lid 12 is turned around the lid hinge portion 13 as a turning center, the upper inclined surface 29A at the tip of the engaging portion 29 is pushed by the lower inclined surface 63A at the tip of the engaging piece 63, When the lock button 19 is tilted so that the engaging portion 29 moves outward, and the lid 12 is pressed so as to close the lid 12, the engaging piece 63 gets over the engaging portion 29, and the engaging piece 63 Thus, the lower portion of the engaging portion 29 is locked, and the lid 12 is fixed to the plug body 10.

  Then, in order to fix the lid body 12 to the stopper body 3 and, in turn, the container body 2 side, the U-shaped lock 20 is rotated upward with the lock rotation shaft 62 as the rotation center, and the locking portions 91 and 91 are attached to the mounting wall. Locked by locking receiving portions 92 and 92 provided in the portions 61 and 61. The inner surface of the front end of the locked U-shaped lock 20 is positioned on the small convex portion 64A in the locking receiving portion 64 provided on the lid body 12, thereby double-locking the lid body 12.

  Thus, in the locked state in which the U-shaped lock 20 is positioned at the upper part of the latch receiving portion 64, the outer surface member 20G is the front side (outer surface side) and the inner surface member 20N is the rear surface side (inner surface side). A fitting portion 82 of the inner surface member 20N having a darker color appears on the tip side of the 20G, and the locking portion can be recognized by visually recognizing the fitting portion 82 and the outer surface member 20G. Further, it is preferable that the outer surface member 20G has a color different from that of the lid body 12 and the lock button 19.

  On the other hand, in order to release the locked state by the U-shaped lock 20, the U-shaped lock 20 is rotated downward with the lock rotation shaft 62 as the rotation center, and the locking provided on the U-shaped lock 20 in the downward state. The protrusions 91 and 91 are engaged with the engagement receiving portions 92A and 92A provided on the mounting wall portions 61 and 61. Further, when the lower portion 28K of the outer body 28 of the lock button 19 is pressed and the lock button 19 is rotated against the spring 65, the engaging portion 29 is retracted to the outside and detached from the engaging piece 63, and the lock is released. As a result, the cover body 12 is biased by the elastic body 14 and rotates in the opening direction.

  Thus, in the unlocked state where the U-shaped lock 20 is in the second position, the inner surface member 20N is the front side (outer surface side), the outer surface member 20G is the rear surface side (inner surface side), and the inner surface is darker than the outer surface member 20G. The member 20N appears, the inner surface member 20N is visually recognized, and the unlocked state can be recognized by the difference from the locked state.

  The U-shaped lock 20 is positioned in the first and second positions by being engaged with the engaging portion 91 and the engaging receiving portions 92 and 92A. However, unlike the painting, the U-shaped lock 20 is colored by the material of the U-shaped lock 20. Therefore, there will be no problems such as paint peeling off when engaging and disengaging.
