A biasing spring (not shown) for generating a biasing force in the rotation direction is provided on the inner side surface of the hinge bearing 56.

  The guide frame 9 sandwiches the slide piece 8 between the two wall portions 91a and 91b on the stopper body 3 side and the two wall portions 93a and 93b on the lid body 5 side, and changes the sliding direction of the slide piece 8 up and down. To guide. In both wall portions 91a and 91b on the side of the plug main body 3, bearing holes 95 of shaft supporting rods for supporting the engaging pieces 7 are formed (see FIGS. 3A and 3B). Also, the outer walls on the front side of both the wall portions 91a and 91b, the lower wall portion 92, and the body portion 31 on the side of the plug body 3 are provided with a housing space 96 (see FIG. (See (a)). The lower wall portion 92 of the guide frame 9 is provided with a stepped portion 92a (protective frame) that contacts the lower end surface of the slide piece 8 and the lower end of the slide piece 8 on the rear side. A biasing coil spring 97 is attached to a surface of the front outer surface of the body portion 31 that forms the accommodation space 96, and generates a biasing force against pushing of the lower portions of the engagement piece 7 and the slide piece 8.

  As shown in FIGS. 4A and 4B and FIGS. 5A to 5F, the engagement piece 7 is formed on the plate-shaped portion 71 and the upper end side of the plate-shaped portion 71. It has a claw portion 72 which engages with the engagement portion 51 (engagement claw 51a), and a shaft portion 74 having a shaft hole 73 through which a shaft support rod for connection with the guide frame 9 is inserted. The shaft portion 74 is provided at a substantially central position in the vertical direction of the plate-shaped portion 71. The side part and the claw part 72 are pulled out outward (see also FIG. 6A).

  The claw portion 72 is formed so that the shape on the front side is substantially the same as the upper end portion of the slide piece 8. When the slide piece 8 is at the upper position, it is hidden by the slide piece 8 and is visible from the front. (See FIG. 5B). In the shape of the claw portion 72 in a side view, the upper surface of the protruding portion is inclined, and the lower surface is substantially horizontal (see FIG. 4A).

  The plate-shaped portion 71 is formed so that the space between the shaft portion 74 and the claw portion 72 is narrow, and the narrow portion is provided on both the left and right sides (toward the side wall portion 82 of the slide piece 8 described later). ) A protruding projection 75 is formed. The length of the protrusion 75 in the vertical direction is substantially equal to the sliding distance of the slide piece 8, and the corners of the upper end and the lower end are chamfered so as to be inclined. A receiving portion for the coil spring 97 is provided at a lower end of the plate portion 71.

  The slide piece 8 surrounds the plate-like portion 81, a pair of side wall portions 82 erected from the rear side of the plate-like portion 81 to sandwich both sides of the engagement piece 7, and a lower end of the engagement piece 7. And a pair of L-shaped guide portions 83 for holding and guiding the same. An operation protrusion 84 is formed on the front side of the plate-like portion 81. The operation protrusion 84 is a mountain-shaped protrusion when viewed from the side, and is disposed slightly lower than the center of the plate-shaped portion 81 in the vertical direction. In addition, the inclination of the lower surface side of the operation protrusion 84 is greater than that of the upper surface side so that a force is easily applied when the slide piece 8 is slid upward. The upper, lower, left and right four side peripheral surfaces of the slide piece 8 are covered with both wall portions 91a, 91b, 93a, 93b, a lower wall portion 92, and an upper wall portion 94 constituting the guide frame 9, and when viewed from the side, A slight part on the front side of the slide piece 8 and the operation protrusion 84 protrude outward.

  The side wall portion 82 is provided at a substantially central position in the up-down direction of the plate-shaped portion 81 and has an elongated hole 85 through which a shaft support rod inserted into the shaft hole 73 of the engagement piece 7 is formed. Therefore, the slide piece 8 rotates together with the engagement piece 7 about the shaft support rod, while the slide piece 8 is guided by the shaft support rod along the long hole 85 so that the slide piece 8 On the other hand, it can slide up and down. Further, since the rear side surface of the engagement piece 7 is supported by the L-shaped guide portion 83, when the lower end of the engagement piece 7 and the lower end of the slide piece 8 are pushed in, the lower end of the engagement piece 7 It rotates together with the engagement piece 7 without any shaking.

  Each of the pair of side wall portions 82 has a protruding portion 86 protruding toward both side portions of the engagement piece 7. The projection 86 has a substantially triangular shape in a rear view, and moves with an appropriate resistance to the upper end or the lower end of the projection 75 of the chamfered engagement piece 7. Therefore, when the slide piece 8 slides up and down with respect to the engagement piece 7, the protrusion 86 gets over the protrusion 75 of the engagement piece 7 while elastically deforming, and the upper end side or lower end of the protrusion 75. Clicking is generated by restoring on the part side.

  In the lock mechanism 6 configured as described above, the slide piece 8 is attached to the engagement claw 51a of the lid 5 while the slide piece 8 is attached to the engagement piece 7 in the vertical direction. Slidable. As shown in FIG. 4A, when the slide piece 8 is at the lower position, the lower end of the slide piece 8 is perpendicular to the step portion 92 a of the lower wall 91 (protective frame) of the guide frame 9. When the lower end of the slide piece 8 is pushed inward from the outside, the slide piece 8 is not pushed in, so that the rotation of the engagement piece 7 attached to the slide piece 8 is also restricted, and the lock mechanism is locked. 6 is locked. At this time, the lower end surface of the slide piece 8 is in contact with the horizontal surface of the step portion 92a, and the slide piece 8 hardly protrudes outward except for the operation protrusion 84. Therefore, for example, when the user puts the thermos 10 in and out of a bag or the like, the slide piece 8 is unlikely to come into contact with any object, and the lock mechanism 6 is prevented from being released against the user's intention. be able to.

  Then, as shown in FIG. 4B, when the slide piece 8 is slid to the upper position, the projection 86 of the slide piece 8 gets over the convex part 75 of the engagement piece 7 (see FIG. 4B). 5 (e) (f)), while giving the user an appropriate operation resistance, and fitting to the upper end side of the convex portion 75 which has become concave with respect to the convex portion 75, the click is clicked. Generate a feeling.

  In addition, in order to provide the operation resistance and the click feeling as described above, for example, when a convex portion is provided on both surfaces of the engagement piece and the slide piece facing each other, when the slide piece is pushed in, If each of the protrusions is worn away, the slide piece may slide up and down without resistance. On the other hand, according to the present embodiment, the pair of protrusions 86 formed on the side wall portion 82 and the pair of protrusions 75 on the engagement piece 7 are in contact with each other in a direction in which the slide piece 8 is pushed. Are orthogonal to each other, so that even when the slide piece 8 is pushed in, the protrusions 86 and the protrusions 75 do not wear away. Further, since the projection 86 and the projection 75 are each two sets, it is less likely to be worn down as compared with the case where only one projection is provided, and even if repeated sliding operations are performed, an appropriate operation resistance and a long-term operation can be obtained. A click feeling can be generated, and the unintended release of the lock mechanism 6 can be more effectively suppressed.

  The projection 75 is provided closer to the claw 72 than the shaft 74, and the projection 86 is provided closer to the upper end of the side wall 82 (see FIGS. 5E and 5F). . The operation projection 84 is provided on the lower end side of the front side of the slide piece 8, and is separated from the projection 75 and the projection 86. Therefore, even if the operation protrusion 84 is pressed by the user's finger, the protrusion 75 or the protrusion 86 is not pressed, so that the protrusion 75 or the protrusion 86 is appropriately deformed when the slide piece 8 slides, You can get a crisp and cheerful click feeling.

  In the present invention, the lock mechanism 6 is released when the slide piece 8 is at the upper position with respect to the engagement piece 7, and is locked when the slide piece 8 is at the lower position with respect to the engagement piece 7. However, the present invention is not limited to the above-described embodiment, and various modifications are possible as long as the lower wall portion (protective frame portion) is in contact with the lower end surface of the slide piece 8 in the locked state. The shapes of the plug body 3 and the lid 5 are not limited to the above-mentioned shapes, and can be changed as appropriate. For example, the lid 5 has no concave portion such as the concave portion 54 and has a more rounded outer shape. Is also good. In addition, the container main body 2 may have any shape, and is not limited to the inner and outer containers 21 described above, and may have a configuration without the strap attaching member 23. Further, for example, the engagement piece 7 may be formed of a flexible resin material. In this case, for example, when the lid 5 is open with respect to the plug main body 3, when the slide piece 8 is at the lower position (locked state) as shown in FIG. If the rigid member 7 is made of a rigid resin material having no flexibility, the lid 5 cannot be closed unless the slide piece 8 is moved to the upper position. If the lid 5 is forcibly closed in this state, the claw 72 of the engagement piece 7 may be damaged. On the other hand, if the engaging piece 7 is formed of a flexible resin material, the engaging piece 7 is slightly deformed, so that the slide 5 is kept in the lower position (locked state) and the lid 5 is moved. Can be closed.
