Further, when the cover plate E slides to the predetermined position at the lower front portion, the third pressure plate is detachably fitted into the pressure reducing hole 35 to block the pressure reducing hole in an airtight and liquid tight manner. A protrusion 65 is provided. Further, an operation knob 66 protrudes from the front upper surface of the cover plate E.

  A locking projection 17 having a small projecting width is provided at a predetermined position in the front and rear direction in the guide groove 14 on both sides of the cap B, and a pair of projecting portions having a small projecting width are provided at the rear predetermined position. A formed locking recess 18 is provided. On the other hand, engagement projections 67 are provided at the rear predetermined positions on both sides of the cover plate E so as to jump over and engage the engagement protrusions 17 from behind to lock the cover plate E to the foremost position. The engaging projection 67 is configured to engage with the locking recess 18 when E is slid to the last part.

In the beverage container 1 configured as described above, in the state shown in FIG. 1, the suction tube 50 of the straw D is folded and closed, and the decompression hole 35 and the outside air introduction hole 36 are also first as shown in FIG. 4 (a). The projection 63 and the second projection 64 are closed. When the engaging protrusion 67 forcibly climbs over the locking protrusion 17 and slides the cover plate E backward from this state, the first protrusion 63 and the second protrusion 64 are moved as shown in FIG. They are removed from the decompression hole 35 and the outside air introduction hole 36 respectively. At this time, the suction cylinder 50 is still in a closed state, and when the pressure inside the container body A is increased due to the influence of the stored liquid or the like, the pressure is reduced to atmospheric pressure through the pressure reducing hole 35. Next, when the engagement protrusion 67 is slid rearward to the position where it engages with the locking recess 18, the upper end of the storage recess 15 is opened, and the suction cylinder 50 is elastically restored by its own elastic restoring force. As shown in the figure, the stored liquid can be sucked by being restored to a straight line shape, and the third protrusion 65 is fitted into the pressure reducing hole 35. At this time, since the inside of the container body A is corrected to the atmospheric pressure, it is possible to prevent inconveniences such as the liquid jumping out. After use, when the engaging projection 67 is forcibly removed from the locking recess 18 and the lid plate E is slid forward, the suction portion D ₁ is deformed at the front edge of the lid plate E. While returning, the upper end opening of the storage recess 15 is closed, and the engaging projection 67 gets over the locking projection 17 and returns to the state shown in FIG.

When the beverage container 1 is washed, for example, if the lid E is slid rearward to force the engagement protrusion 67 over the rear protrusion that forms the locking recess 18, the removal recess 13 The lid plate E can be easily removed. Further, after emerged threaded cap B from the container body A, the suction portion D ₁ of the straw D can be easily removed from the cap B If pulled out with a strong force because it is formed of an elastomeric, also the main portion D ₂ suction it can be easily detached from part D _1. Furthermore, since the seal member C is also formed of an elastomer, it can be easily removed from the cap B by grasping the finger-hanging protrusion 31 and pulling it out with a strong force, and the whole can be disassembled into pieces. Can be washed. Assembling after disassembly may be performed by attaching the straw plate D and the seal member C to the cap, attaching the cover plate E, and screwing the cap body A.

5 to 7 show other examples. In the example of FIG. 1, the cover plate E has the entire length of the belt-shaped recess 12 and a hanging wall 68 is formed on the outer surface of the mounting cylinder 10 from the rear edge. It is suspended. Further, the locking recess 18 is not provided, and the grips 19 project from the both sides of the cap B mounting cylinder 10. The other configuration is the same as that of the example of FIG. Of course, it is possible to adopt the handle even in the example of FIG.

  In the case of this example, when the lid E is slid rearward, as shown by the two-dot chain line in FIG. 5, the lower end edge of the vertical wall 68 abuts the outer surface of the container body A, and the rearmost position can be specified. Further, when disassembling, the cover plate E cannot be removed unless the cap B is removed from the container body A.
