When the pressing of the operating lever 34 is released, the operating portion 341 of the operating lever 34 is rotated and returned upward by the returning force of the valve firing strip 323, and the valve body 322 returns to the closed state.

When the beverage container is used, the stopper 3 is in a state in which the upper member 3b is fitted and mounted on the lower member 3a. It penetrates the holes 315 and 333 and protrudes outward in the radial direction, and the lower member 3a and the upper member 3b are integrated. The attachment / detachment of the stopper 3 to / from the shoulder member 2 is performed by retracting the locking portion 351 by operating the attachment / detachment lever 35 (retracting operation toward the center of the stopper against the urging force) and releasing the lever when the attachment / detachment lever 35 is released. This is done by engaging and unlocking the shoulder member 2 in the locking recess 24 by protruding outward in the radial direction due to the urging force of 353.

By providing the blocking plate portion 343 on the operating lever 34, the collision portion 354 collides with the blocking plate portion 343 in a state where the tip of the locking portion 351 of the attachment / detachment lever 35 is located in the outer indentation hole 315, and the retracting operation is performed. Since it is blocked, when the operating lever 34 is lifted by the urging force of the valve ejection rod 323, the operation of the attachment / detachment lever 35 is limited to the range of protrusion / non-projection from the stopper peripheral side surface 311 of the locking portion 351. Therefore, the tip of the locking portion 351 does not come out from the outer infestation hole 315 to the back (FIGS. 5 and 6).

After removing the plug 3 from the shoulder member 2, when the operation lever 34 is pushed down to release the blocking plate portion 343 from the operating range of the collision portion 354 and the detachable lever 35 is retracted, the blocking plate portion 343 is in the way. Therefore, the tip of the locking portion 351 can be moved to the back from the outer infestation hole 315 so as to be located in the inner infestation hole 333 (FIG. 7), and when the lower member 3a is pulled downward in this state, the upper member The fitting and mounting with 3b is released, and the lower member 3a and the upper member 3b are separated (FIG. 8).
Therefore, the attachment / detachment of the plug 3 to / from the shoulder member 2 can be performed in a state where the upper and lower members 3a and 3b are integrated by operating only the attachment / detachment lever 35 without operating the operation lever 34. On the other hand, when cleaning the inside of the plug body 3, the lower member 3a and the upper member 3b can be easily disassembled by retracting the detachable lever 35 with the operation lever 34 lowered.

However, in the above-mentioned conventional beverage container, only a part of the inside of the stopper 3 can be washed, and the inside of the internal liquid outflow passage portion 313, which is easily contaminated with liquid, cannot be washed.

The attachment / detachment lever 35 has an L-shape, and the horizontal plate portion is a locking portion 351 that protrudes from the outer protrusion / exit hole 315 on the side of the plug body, and the upright portion is projected upward in the operation recess 334 to form an operation portion 352. Further, a lever ejection 353 that urges the detachable lever 35 in the outward direction in the left-right direction is attached, and when the detachable lever 35 retracts by a predetermined distance (movement toward the center of the plug), the operation lever 34 A collision portion 354 that advances into the operating range of the blocking plate portion 343 is provided.

When supplying the beverage, the shoulder member 2 is fixed to the container body 1 in advance, the beverage is poured into the container body 1 with the stopper body 3'removed from the shoulder member 2, and then the stopper body 3'is shouldered. It is attached to the member 2. At this time, the directions of the outlet 401 of the internal liquid outflow passage portion 313'and the spout 22 are matched. When the operation portion 341 of the operation lever 34 is pressed with a finger against the valve ejection rod 323, the space between the valve body 322 and the lower opening end 316 of the peripheral side surface 311 opens, and the inlet 400 of the internal liquid outflow passage portion 313'is the container body 1. It will be released inside. As a result, the beverage in the container body 1 can be poured into a cup (not shown) via the internal liquid outflow passage portion 313'and the spout 22 (see arrow f in FIG. 12). When the pressing of the operating lever 34 is released, the operating portion 341 of the operating lever 34 is rotated and returned upward by the returning force of the valve firing strip 323, and the space between the valve body 322 and the lower opening end 316 is closed, and the internal liquid outflow passage portion 313. It returns to the state where the entrance 401 and the inside of the container 1 are blocked.

When the beverage container is used, the stopper 3'is in an assembled state in which the upper member 3b'is fitted and mounted on the lower member 3a'. The lower member 3a'and the upper member 3b' are integrated with each other by penetrating the inner indentation hole 333 and the outer infestation hole 315 and projecting outward in the radial direction. The attachment / detachment of the stopper 3'to / from the shoulder member 2 is performed by retracting the locking portion 351 by operating the attachment / detachment lever 35 (retracting operation toward the center of the stopper against the urging force of the lever ejection force 353) and retracting the attachment / detachment lever 35. The locking portion 351 protrudes outward in the radial direction due to the urging force of the lever ejection force 353 accompanying the release, so that the shoulder member 2 is locked and released from the locking recess 24.

By providing the blocking plate portion 343 on the operation lever 34, in a state where the tip of the locking portion 351 of the attachment / detachment lever 35 is located in the outer indentation hole 315, even if the attachment / detachment lever 35 is to be retracted, the collision portion 354 will occur. Since the operation lever 34 collides with the blocking plate portion 343 and the retracting operation is prevented, when the operating lever 34 is lifted by the urging force of the valve ejection rod 323, the operation of the attachment / detachment lever 35 protrudes from the peripheral side surface 311 of the locking portion 351. -Limited to the non-protruding range, the tip of the locking portion 351 does not come out from the outer infestation hole 315 to the back (see FIGS. 13 and 14).

After removing the stopper 3'from the shoulder member 2, the operation lever 34 is pushed down to release the blocking plate portion 343 from the operating range of the collision portion 354, and the detachable lever 35 is retracted toward the center of the stopper 3'. Then, since the blocking plate portion 343 does not interfere, the tip of the locking portion 351 moves to the back from the outer haunting hole 315 and escapes from the outer hauling hole 315 (see FIG. 15), and in this state, the lower member 3a'is lowered. When pulled to, the fitting and mounting with the upper member 3b'is released, and the lower member 3a'and the upper member 3b' are separated (see FIGS. 16 and 17).
Therefore, when attaching / detaching the plug 3'to / from the shoulder member 2, the lower member 3a'and the upper member 3b' can be integrated by operating only the attachment / detachment lever 35 without operating the operation lever 34. can. On the other hand, when cleaning the inside of the plug 3', the plug 3'is easily disassembled into the lower member 3a'and the upper member 3b' by retracting the attachment / detachment lever 35 with the operation lever 34 lowered. On the contrary, with the operation lever 34 lowered and the attachment / detachment lever 35 retracted, the upper member 3b'is fitted to the lower member 3a', the inner indentation hole 333 and the outer indentation hole 315 are aligned, and the attachment / detachment lever is attached. By releasing the 35 and projecting the locking portion 351 to the outside in the radial direction through the inner indentation hole 333 and the outer infestation hole 315 by the urging force of the lever ejection 353, it can be easily assembled.

In this embodiment, after the plug 3'is disassembled, the upper surface portion exposed upward when the upper member 3b'is separated from the internal liquid outflow passage portion 313'is opened, and stains due to beverages are likely to remain. The inside of the internal liquid outflow passage portion 313'is largely exposed to the outside so that it can be washed. That is, a square cleaning opening 403 is formed on the upper surface side of the internal liquid outflow passage portion 313', and a substantially square plate-shaped opening lid portion 420 that detachably closes the opening 403 is attached. There is. The opening 403 opens upward from the upper end of the U-shaped side wall 404 of the internal liquid outflow passage portion 313'.

As shown in FIG. 19, the opening lid portion 420 has a downwardly convex cross section, a lid plate 421 having an upper peripheral portion formed in a flange shape, and a peripheral groove 422 formed in the lower peripheral edge portion of the lid plate 421. It is composed of a square frame-shaped packing 423 that is detachably fitted to the container. When the opening lid 420 is fitted into the opening 403, the flange 424 comes into contact with the upper end surface 405 of the side wall 404, and the packing 423 is in close contact with the inner circumference near the upper end of the opening 403, so that the internal liquid outflow path is formed. The waterproof seal of the portion 313'and the floating prevention of the opening lid portion 420 are performed. The front end portion 425 of the flange portion 424 projects slightly forward, and when the opening lid portion 420 is fitted into the opening portion 403, it abuts on the upper wall 402 of the outlet 401 formed on the peripheral side surface 311 to cause the outlet 401. There is no gap between the opening lid and the opening lid 420.

When using the tabletop pot, the opening lid portion 420 is fitted into the opening portion 403 while the front end portion 425 of the flange portion 424 is brought into contact with the upper wall 402 of the outlet 401 in advance. The inside of the internal liquid outflow passage portion 313'other than the outlet 401 can be isolated from the outside to prevent the liquid from leaking from the beverage.
When the plug 3'is removed from the shoulder member 2 and disassembled into the upper member 3b'and the lower member 3a' for cleaning, the opening lid portion 420 is further removed from the opening 403 to form an internal liquid outflow path portion 313'. The inside of the valve mechanism 32 is largely exposed to the outside so that it can be washed (see FIG. 18; in FIG. 18, the valve mechanism 32 is separated).

According to this embodiment, after the plug 3'is disassembled into the lower member 3a'and the upper member 3b', the opening lid portion 420 is removed to form an internal liquid outflow path portion 313' provided in the lower member 3a'. The inside can be exposed and washed.

In addition to the opening lid portion 420 shown in FIG. 19, as shown in the opening lid portion 420A of FIG. 20, an opening is provided by separately preparing a type having a larger protrusion amount protruding downward from the lid plate 421A. By replacing the lid portion 420 with the opening lid portion 420A and attaching it to the opening portion 403, the flow path of the internal liquid outflow passage portion 313'may be narrowed, the flow rate may be reduced, and the beverage may be supplied little by little. .. In addition to changing the amount of protrusion, one or more obstruction plates are projected into the flow path of the internal liquid outflow path from multiple locations on the lower surface of the opening lid so that the obstruction plate does not completely block the flow path. , Multiple types of opening lids with different numbers or lengths of baffles may be prepared to adjust the flow rate. In short, multiple types with different inward protrusion structures of the internal liquid outflow path of the opening lid. The flow rate may be adjustable by replacing the opening lid.

Further, in the above-described embodiment, the disassembly of the plug body has been described by taking as an example a case where the attachment / detachment lever is retracted while the operation lever is pressed, but the present invention is not limited thereto. Of course, it may be configured by another disassembly / assembly structure, for example, the lower member and the upper member can be detachably disassembled by a screw structure.
Further, although the packing for sealing the water stop between the opening lid and the opening is provided on the lower peripheral edge of the opening lid, it may be provided on the peripheral edge of the opening.

The present invention can be applied to a beverage container such as a tabletop pot in which the plug body can be disassembled and the internal liquid outflow passage portion can be exposed to the outside.
