[Problems to be Solved by the Invention] In the above-mentioned conventional cap, since the front end of the opening / closing plate has to be pushed up with respect to the cap body, it is necessary to attach a finger hook to the front end of the opening / closing plate.

This proposal is one in which a lid plate that closes the upper surface of the cap body is pivotally attached at each of the rear portions thereof, and the front surface of the recessed portion provided in the upper front surface of the cap body is closed by a front wall that hangs from the front portion of the lid plate. A rocking plate is formed by separating the left and right parts of the front wall and the upper part of the front wall by a continuously formed split groove, leaving the lower end part of the front wall, and ribs are provided vertically on the rear surface of the rocking plate. The rib lower surface is placed on the bottom surface of the recess, and the upper portion of the rocking plate is pushed backward, so that the rocking plate is rotated about the lower surface of the rear end of the rib as a fulcrum. The lid plate front portion is pushed up via both the left and right portions, and the lid plate engaging means provided on the upper rear surface of the recess and the lid plate front portion are disengaged.

"Means for Solving Problems" The cap body 6 having the pouring hole 8 formed in the top wall 7 and the rear part of the opening / closing plate 19 are pivotally attached to the rear part of the upper end of the cap body.
A lid plate 18 that hangs a stopper 24 fitted into the pouring hole from the back surface of the opening / closing plate, and a second concave portion 13 having a front surface and an open upper surface is provided at the upper front end of the cap body, and the concave front surface is formed. A front wall 27 to be closed is hung from the front edge of the opening / closing plate 19, and vertical split grooves 28, 28 are formed on the left and right sides of the front wall 27 from the upper end of the front wall to near the lower end, and the upper ends of both vertical split grooves. A horizontal dividing groove 29 that connects the vertical dividing groove, the horizontal dividing groove, and the lower edge of the front wall is formed in the rocking plate portion 31, and the rocking plate portion 31 is formed. By pushing the upper part of the moving plate part rearward, the front wall and the front part of the opening / closing plate rise, and the cover plate engaging means 26 provided on the upper part of the rear surface of the second recess and the front part of the opening / closing plate 19 can be disengaged. From the rear surface of the oscillating plate portion, a rib 32 that makes contact with the lower end surface of the bottom surface 13a of the second recess 13 is projected.

[Operation] When the upper part of the front surface of the rocking plate portion 31 is pushed rearward from the state shown in FIG. 1, the rib 32 is drawn as shown by a chain double-dashed line in FIG.
Although the lower surface of the rear end portion tries to descend, the lower surface of the recess interferes with the lowering, so that the front portion of the rocking plate portion is pushed up, and the front wall 27 continuous at the lower left and right sides of the front portion also. Therefore, the front portion of the opening / closing plate 19 that is pushed up and therefore hangs down the front wall is also pushed up, and the lid plate engaging means 26 for holding the lid plate closed state is disengaged. If a spring for urging in the opening direction is attached to each of the rear pivot parts of the cap body 6 and the cover plate 18, the cover plate engaging means is simply disengaged to open the cover plate 18, and as described above. If an elastic reversing mechanism of the point hinge is provided at the pivotally connecting portion between the cap body and the lid, the lid is elastically reversed by further pushing up the front portion of the lid from the disengaged state of the lid plate engaging means. Open. The rocking plate portion 31 elastically returns by releasing the backward push.
