A lid 3 is provided. The lid 3 also functions as a cup for drinking. A first screw portion 10 and a second screw portion 11 having an outer diameter smaller than that of the first screw portion 10 are provided on the upper end portion of the container body 1. The first screw portion 10 and the second screw portion 11 are integrally formed of resin and are attached to the upper portion of the cylindrical portion 12 of the container body 10. The cylindrical portion 12 is made of metal.

  FIG. 2 is a cross-sectional view showing the configuration of the plug 2. The plug body 2 includes a plug body portion 20, a water injection port 21 that is attached to and supported by the plug body portion 20, and a female screw portion 22 that is attached to the upper portion of the plug body portion 20. On the external appearance of the female screw portion 22, oval projections 22a are formed at equal intervals along the circumferential direction so as to be easily turned by hand (see FIG. 4). Further, the plug 2 includes a water inlet lid 23 that opens and closes the upper portion of the water inlet 21, an operation member 24 that opens and closes the water inlet lid 23, a valve body 25 that moves in conjunction with the operation member 24, and a valve body 25. A coil spring 26 (corresponding to the first biasing means) that biases in the closing direction and a spring holding cap 27 for holding the coil spring 26 are provided.

  FIG. 3 is a cross-sectional view showing the configuration of the water injection port 21. The water injection port 21 is formed in a trumpet shape having a larger diameter (expanding end) toward the top. A groove 21a is formed in the lower portion of the water injection port 21 along the circumferential direction, and a rubber ring packing 28 is inserted. In addition, a positioning step portion 21b is integrally formed on the position where the packing 28 is attached.

  The plug body 2 is formed with a fitting hole 20a for inserting the water injection port 21, and the water injection port 21 can be inserted into the fitting hole 20a from above. At this time, since the outer diameter of the packing 28 is inserted while being slightly compressed (press-fitted), the water injection port 21 can be held in the fitting hole 20a by a frictional force. The fitting hole 20a is provided with an upper end surface 20b. When the water injection port 21 is inserted from above, the positioning stepped portion 21b comes into contact with the upper end surface 20b, so that it cannot be inserted further below. Thereby, the water inlet 21 can be positioned stably in the up-down direction.

  An operation portion holding member 200 (this operation portion holding member 200 is also included in the plug body main body 20) is provided on the upper portion of the plug body main body 20, and the water inlet cap 23 and the operation member 24 are attached and held.

  The operation member 24 is supported by the rotation shaft 29 so as to be rotatable with respect to the operation unit holding member 200. The water inlet lid 23 is provided with a rubber packing member 30 that seals the upper part of the water inlet 21 when the water inlet lid 23 is closed.

  The operation member 24 is rotatably supported around the first rotation shaft 29. The operation member 24 is provided with a recess in the upper part, and functions as an operation unit 24a for operation with a finger. The lower part of the operation member 24 functions as a valve operating part 24b formed in a spherical shape. A concave portion 24c is integrally formed adjacent to the valve operating portion 24b. A coil spring 32 (corresponding to the third urging means) that urges the operation member 24 in the closing direction is provided (see FIG. 2A). The coil spring 32 is attached so as to be inserted into the first rotating shaft 29, one of the arm portions 32a at both ends of the coil spring 32 is hung on the operation member 24, and the other arm portion (not shown) is operated. It is hung on the part holding member 200.

  The water injection lid 23 is supported so as to be rotatable around the second rotation shaft 33. The second rotation shaft 33 is provided on the operation member 24. Further, a coil spring 34 (corresponding to the second urging means) for urging the water inlet lid 23 to the closed position (position where the water inlet 21 is closed) is provided (see FIG. 2). The coil spring 34 is attached so as to be inserted into the second rotating shaft 33, and one of arm portions (not shown) at both ends of the coil spring 34 is hung on the operation member 34, and the other arm portion (not shown). ) Is hung on the water inlet lid 23. With this configuration, the water inlet lid 23 can be rotated with respect to the operation member 24 alone.

  Further, as shown in FIG. 2, the contact portion 24 d formed integrally with the operation member 24 below the second rotating shaft 33 and the contact portion 23 a formed integrally with the water filling port lid 23 are mutually connected by the biasing force of the coil spring 34. It is urged to abut. Accordingly, the water inlet lid 23 cannot further rotate counterclockwise with respect to the operation member 24 in FIG. It can be rotated only in the clockwise direction.

  In addition, as shown in FIG. 2, the second rotation shaft 33 is located above the first rotation shaft 29 and slightly closer to the water inlet. With such a positional relationship, the arrangement configuration of the water inlet lid 23 can be facilitated, and the operation of the water inlet lid 23 and the operation of the operation member 24 can be performed individually and smoothly. Moreover, the operation | movement with respect to the operation member 24 of the water inlet lid 23 can be ensured reliably.

  The valve body 25 includes a shaft-shaped guide portion 25a and a disk portion 25b formed integrally with a lower portion of the guide portion 25a. A ring-shaped packing member 31 is attached to the lower end of the plug body 20, and the flow path is closed when the disk portion 25 b comes into contact with the packing member 31. When the valve body 25 moves downward, the disk portion 25b and the packing member 31 are separated from each other and the flow path is opened.

  A guide hole 20c is formed at the center of the plug body 20 and guides the valve body 25 in the vertical direction. The upper end surface 25 c of the valve body 25 is formed in a spherical shape and abuts on the valve operating portion 24 b of the operation member 24 by the urging force of the coil spring 26. Further, a groove 25d is formed in the upper part of the valve body 25, and a spring holding cap 27 is integrally attached.

  The spring holding cap 27 is formed in a cap shape with the lower part opened, and a coil spring 26 that biases the valve body 25 in the closing direction is held. The coil spring 26 is held between a spring holding cap 27 and a pedestal portion 20 d formed integrally with the plug body 20. Since the spring holding cap 27 is constantly biased upward by the biasing force of the coil spring 26, the valve body 25 is also always biased upward. That is, the disc part 25b of the valve body 25 and the packing member 31 are brought into contact with each other and urged in a direction to close the flow path. As described above, the shape of the upper end surface 25c of the valve body 25, the shape of the valve operating portion 24b of the operation member 24, the coil spring 26, and the spring holding cap 27 function as a valve body opening / closing mechanism.

<Operation>
Next, operation | movement of the stopper of the drink container shown in FIGS. 1-4 is demonstrated. First, the operation when the water inlet 21 is opened and the beverage is taken out will be described. 5 and 5A are cross-sectional views showing a state when the operating member is operated to the open position. FIG. 5A is a cross-sectional view corresponding to FIG. 2A.

  In FIG. 2, the operation member 24 is located at the closed position, and the upper end surface 25 c of the valve body 25 pushes up the valve operation portion 24 b of the operation member 24 from below. Accordingly, a force acts to rotate the operation member 24 around the rotation shaft 29 in the counterclockwise direction. As a result, the water inlet lid 23 is urged in a direction to close the water inlet 21. Further, since the coil spring 32 also directly biases the operating member 24 in the closing direction, the operating member 24 can be held in the closed position in a stable state.

  In order to open the water injection port 21, the operation part 24a of the operation member 24 is pushed downward. That is, in FIG. 2, the operation member 24 is rotated in the clockwise direction of the rotation shaft 29. As a result, the valve body 25 is pushed downward against the urging force of the coil spring 32. When the valve body 25 is lowered, a gap is formed on the bottom surface side of the packing member 31 and the flow path is opened.

  When the operation member 24 is rotated from the open position, the upper end surface 25 c of the valve body 25 is fitted into the recess 24 c of the operation member 24. Therefore, the operation member 24 can maintain its posture in a stable state at the open position. If the beverage container A is tilted while maintaining this state, the beverage inside the container body 1 can be extracted from the tip of the water inlet 21 (the flow of the beverage is indicated by an arrow). In addition, when the operation member 24 is rotated, the water filling lid 23 is also rotated in the same manner.

  As described above, the water inlet lid 23 is supported by the operation member 24 by the second rotary shaft 33 and the coil spring 34, so that only the water inlet lid 23 can be rotated around the second rotary shaft 33 alone. FIG. 6 shows a state where only the water inlet lid 23 is rotated from the state shown in FIG. It should be noted that the water inlet lid 23 cannot rotate counterclockwise from the position shown in FIGS. 5 and 5A, but can only rotate clockwise. The water inlet 21 can be taken out by further opening the water inlet lid 23 as shown in FIG.

  Since the water injection port 21 is shaped like a trumpet, the tip can be taken out with a finger. Only the water injection port 21 can be taken out and cleaned sufficiently. Moreover, the plug 20 after the water inlet 21 is removed can also be washed. Therefore, it is possible to sufficiently clean the inside corners.

  When the finger holding the water inlet lid 23 is released from the state of FIG. 6, the state returns to the state of FIG. 5 by the urging force of the coil spring 34. After cleaning the water injection port 21, the water injection port 21 is returned to the plug 2. If the water injection port 21 is inserted into the fitting hole 20a of the plug body 20 and pushed into the position where the positioning step 21b of the water injection port 21 abuts against the upper end surface 20b of the plug body 20, the water injection port 21 is attached. Is completed.

  When closing the water inlet lid 23 from the state of FIG. 5, the upper surface of the water inlet lid 23 may be pressed with a finger. As a result, the contact portion 23 a of the water filling lid 23 pushes the contact portion 24 d of the operation member 24. As a result, the water inlet lid 23 and the operation member 24 are integrally rotated around the first rotation shaft 29 in the counterclockwise direction and returned to the state shown in FIG. The valve body 25 also returns to the closed state by the urging force of the coil spring 26.

  FIG. 1 shows a state in which the lid 3 is covered from the top of the stopper 2. In the state where the lid 3 is covered, the movement of the water inlet lid 23 and the operation member 24 is restricted on the upper inner surface of the lid 3 so that the water inlet lid 23 and the operation member 24 do not open carelessly.

<Another embodiment>
The plug body 20 is composed of a plurality of members, but may be composed of one member or a combination of two or more members.

  The shape of the water injection port does not have to be a trumpet shape as in the present invention. For example, the cross section may be a square shape as long as it is formed in a cylindrical shape. The water injection port is held by press-fitting (frictional force), but the present invention is not limited to this. For example, the stopper body portion may be locked using an appropriate locking mechanism.
