  Further, in a state in which the engagement protrusion 53 of the lock release button 51 is engaged with the engagement recesses 24a, 24b, 24c, that is, in a state in which one-way or two-way rotation of the outer lid 10 with respect to the inner lid 20 is restricted, When the lock release button 51 is pushed inward in the radial direction of the outer lid 10, the engagement of the engagement projections 53 with the respective engagement recesses 24 a, 24 b, and 24 c is released, and the rotation restriction of the outer lid 10 with respect to the inner lid 20 is released. It is supposed to be.

  However, the lock release button 51 in a state where the engagement protrusion 53 is engaged with the engagement recess 24b is pressed to release the engagement of the engagement protrusion 53 with the engagement recess 24b, and the outer lid 10 is viewed from above. Even if it is attempted to rotate in the clockwise direction, the locking piece 18 of the outer lid 10 abuts on the regulating piece 25a of the inner lid 20 so that the rotation in that direction is regulated, and the engaging projection 53 is engaged with the engaging recess. Push the lock release button 51 engaged with the engagement recess 24c to release the engagement of the engagement protrusion 53 with the engagement recess 24c, and rotate the outer lid 10 in a counterclockwise direction as viewed from above. Even when the locking piece 18 of the outer lid 10 comes into contact with the restriction piece 25b of the inner lid 20, rotation in that direction is restricted.

  The elevating means is formed on a pair of opposed convex portions 17 formed on the inner cylindrical portion 13 of the outer lid 10, and on the bottomed cylindrical portion 41 of the elevating member 40 which is hung on the pair of opposed convex portions 17. And a pair of inclined steps 43, and the inclined step 43 is hung on the projection 17 of the outer lid 10 in a state where the elevating member 40 is prevented from rotating by the inner lid 20. When the rotating member 10 is rotated clockwise in a state viewed from above with respect to the inner lid 20, that is, to the lower side of the inclined step portion 43, the elevating member 40 rises, and in the opposite direction, that is, the higher When turned to the side, it descends.

  In the state where the engagement projection 53 of the lock release button 51 is engaged with the engagement recess 24a, the highest part of the inclined step portion 43 is hooked on the projection 17 of the outer lid 10, and the elevating member 40 is Although it is in the most lowered state, when the engagement projection 53 of the lock release button 51 is engaged with the engagement recess 24b, the lowest part of the inclined step portion 43 is hooked on the projection 17 of the outer lid 10. As a result, the elevating member 40 is in the highest state.

  In the beverage container 1 configured as described above, when the mouth 2a of the container body 2 is closed by the lid 3, the engagement protrusion 53 of the lock release button 51 is engaged as shown in FIG. As shown in FIG. 11 (a), the packing 30 and the elevating member 40 of the lid 3 in the state in which the elevating member 40 is most lowered as shown in FIG. Until the outer flange 32 of the packing 30 contacts the upper end of the mouth 2a, and then inserts it into the mouth 2a of the container body 2 in a clockwise direction with the outer lid 10 viewed from above (the closing direction). ), The engagement protrusion 53 of the lock release button 51 moves along the inner peripheral surface of the engagement ring portion 24 while being pressed against the inner peripheral surface of the engagement ring portion 24. 53 engages with the engaging recess 24b and is held in that state. In a state where the packing 30 and the elevating member 40 of the lid 3 are inserted into the opening 2a of the container body 2, the contact frictional force between the packing 30 and the opening 2a of the container body 2 is reduced by the outer lid 10 and the inner lid 20. When the outer lid 10 is rotated, the inner lid 20 does not rotate together, and only the outer lid 10 rotates.

  In this state, as shown in FIGS. 11B and 13, the lowest part of the inclined step portion 43 is hooked on the convex portion 17 of the outer lid 10, and the elevating member 40 rises most along with it. Therefore, the outer flange 45 of the elevating member 40 against which the lower end of the packing 30 is in contact abuts the lower end of the packing 30 to elastically deform the flat portion so that the bulging portion 33 projects radially outward. The flattened bulging portion 33 that protrudes radially outwardly comes into close contact with the inner peripheral step 2b of the container main body 2, whereby the container main body 2 is sealed in a liquid-tight state, and the lid is closed, that is, The lid 3 is held in a state where the lid 3 is prevented from being pulled out from the mouth 2a of the container body 2.

  To remove the lid 3 attached to the container body 2 in this manner, the lock release button 51 is pushed in to release the engagement of the engagement projection 53 with the engagement recess 24b, and the outer lid 10 is removed from above. When rotated 95 degrees in a counterclockwise direction (cover opening direction) in a state in which it is viewed, the engagement protrusion 53 is engaged with the engagement concave portion 24a, and returns to the state shown in FIGS. The lid 3 can be removed from the container body 2 by pulling it out of the mouth 2 a of the container body 2.

  In order to remove the elevating member 40 from the lid 3 in the state shown in FIG. 12 thus removed from the container main body 2, as shown in FIG. Is pushed into the inner cylindrical portion 13 of the outer lid 10, the lock release button 51 is pushed in to release the engagement of the engaging projection 53 with the engaging concave portion 24a, and the outer lid 10 is viewed from above. When rotated 35 degrees in the counterclockwise direction, as shown in FIG. 15, the engagement protrusion 53 engages with the engagement concave portion 24 c and the pair of opposing convex portions 17 of the outer lid 10 move the guide path of the elevating member 40. When the elevating member 40 is pulled down in this state, the pair of opposing convex portions 17 of the outer lid 10 move to the upper end side of the elevating member 40 along the guide path 44, as shown in FIG. As shown in, the lifting member 40 can be removed. That.

  In order to attach the elevating member 40 removed from the lid 3 to the lid 3 in this manner, the packing 30 is fitted to the notch formed in the inner flange portion 34 of the packing 30 by fitting a pair of ridges 42 of the elevating member 40. When inserted into the inside, a pair of convex ridges 42 are fitted into a pair of opposed vertical grooves 26 formed on the inner peripheral surface of the inner cylindrical portion 21 of the inner lid 20, and the pair of opposed convex portions 17 of the outer lid 10 are guided. When the lifting member 40 is further pushed in while the bulging portion 33 of the packing 30 is elastically deformed, the pair of convex portions 17 enters the lower portion of the guide path 44 as shown in FIG. I do. In this state, when the lock release button 51 is pushed in to release the engagement of the engagement projection 53 with the engagement recess 24c and the outer lid 10 is rotated clockwise by 35 degrees in a state viewed from above, The engagement projection 53 engages with the engagement recess 24a, and as shown in FIG. 14, the pair of projections 17 enter the thin portion below the inclined step 43, so that the pushing force of the lifting member 40 is released. Then, the outer flange portion 45 of the elevating member 40 is pushed down by the restoring force of the elastically deformed packing 30, and returns to the lid 3 in the state (opened state) shown in FIG.

  As described above, the beverage container 1 has the packing 30 fitted to the inner cylinder 21 of the inner lid 20 and the elevating member 40 supported by the inner cylinder 21 fitted into the mouth 2 a of the container body 2. Then, just by rotating the outer lid 10 by 95 degrees, the outer flange 45 of the elevating member 40 pushes up the lower end of the packing 30 to elastically deform the bulging portion 33 of the packing 30 so that the inner peripheral step of the container body 20 is formed. Since the mouth 2a of the container body 2 is closed by being pressed against the container 2b in a liquid-tight state, a screw-in type in which the mouth of the container body cannot be completely closed without rotating the lid about 360 degrees. As compared with the beverage container, the rotation angle required for opening and closing the lid 3 is 1/3 to 1/4, so that the opening and closing operation of the lid 3 is not troublesome, and the packing 30 is opened and closed when the lid 3 is opened and closed. Since the inner peripheral step 2b does not slide, 30 is hardly worn, the effect is obtained that the sealing performance hardly decreases.

  Further, since the lid 3 and the container main body 2 do not have a threaded portion, it is possible to obtain an effect that dirt hardly accumulates and cleaning does not take much time.

  In addition, the beverage container 1 is formed on the outer peripheral surface of an elevating member 40 that is supported to be able to move up and down while being prevented from rotating around the inner cylindrical portion 21 of the inner lid 20. Since the stepped portion 43 which is inclined in the up-down direction employs a lifting means which is hung on a pair of opposed convex portions 17 formed on the inner peripheral surface of the inner cylindrical portion 13 of the outer lid 10, the inner lid is used. When the outer lid 10 is rotated with respect to 20, the elevating member 40 moves up and down relative to the inner lid 20 by the height difference of the inclined step portion 43, and the elevating member 40 can be moved up and down with a simple and compact configuration.

  In addition, the beverage container 1 restricts rotation of the outer lid 30 with respect to the inner lid 20 in a state where the lower portion of the packing 30 is pressed against the inner peripheral step 2b of the container body 2 in a liquid-tight manner. Since the lock means 50 is provided, in the locked state, the elevating member 40 descends with respect to the inner lid 20, that is, the liquid-tight state of the inner peripheral step 2b of the container body 2 by the packing 30 is released. Therefore, it is possible to prevent the beverage filled in the container body 2 from leaking.

  Further, in the beverage container 1, the packing 30 is detachably fitted to the inner cylinder portion 21 of the inner lid 20 and the elevating member 40 is detachably supported by the inner lid 20. Cleaning can be performed with the packing 30 and the elevating member 40 removed, and the workability of cleaning the lid 3 is good.

  Further, in the beverage container 1, the packing 30 has an outer flange portion 32 projecting radially outward at an upper end portion, and the outer flange portion 32 is provided between the upper end portion of the mouth 2 a of the container body 2 and the inner lid 20. In the closed state, the inner peripheral step 2b of the container body 2 and the upper end 2a of the opening 2a of the container main body 2 are sandwiched in a liquid-tight state between the lower surface of the outer flange portion 22 and the outer flange portion 22. The portion is in a liquid-tight state, the sealing performance is improved, and leakage of the beverage filled in the container body 2 can be more reliably prevented.

  In the above-described embodiment, the opening / closing rotation angle (the angle between the open position α and the closed position β) of the outer cover 10 with respect to the inner cover 20 is set to 95 degrees, but is not limited thereto. Instead, it may be set appropriately within the range of 90 degrees to 120 degrees.

  Further, in the above-described embodiment, a pair of opposed convex portions 17 formed on the inner cylindrical portion 13 of the outer lid 10 and the bottomed cylindrical portion 41 of the elevating member 40 hung on the pair of opposed convex portions 17. The lifting means is constituted by the pair of inclined steps 43 formed in the above. However, the present invention is not limited to this, and various mechanisms capable of converting the rotation of the outer lid into the lifting of the lifting member may be employed. Can be.

  The present invention can be used as a portable beverage container such as a portable thermos bottle or a water bottle.
