At this time, in the space between the sealing material 18 and the lid 21, the portion located above the open portion R1 (hereinafter referred to as the distribution space R2) is covered on both sides in the left-right direction by the regulating portion 32, and is also covered. The rear part is covered with the main plate portion 44.

As described above, according to the cup container 1 with a lid of the present embodiment, the distribution space R2 is covered from three directions, so that the content poured out through the open portion R1 of the sealing material 18 is the sealing material 18. Accumulation on the upper surface can be suppressed.
Since the lid 21 is provided with the locking portion 28b, the main plate portion 44 can be held in the broken posture in which the sealing material 18 is broken, so that the distribution space R2 is covered from three directions. It can be held securely.

A locked portion 47b connected to the hinge portion 43 is formed in the main plate portion 44, and an entry hole 28a is formed in the top wall portion 25. Since the locked portion 47b is arranged in the vicinity of the hinge portion 43 which is the center of rotation of the main plate portion 44, a force larger than the force applied to the main plate portion 44 acts on the locked portion 47b, and the main plate portion The distance that the locked portion 47b moves is shorter than the distance that 44 is moved. Therefore, it is possible to suppress the force required to lock the locked portion 47b to the locked portion 28b and the amount of rotational movement of the locked portion 47b, which provides excellent operability with a simple configuration. be able to.
The broken portion 42 faces the outer peripheral portion of the sealing material 18 in the vertical direction. Therefore, the distribution space R2 can be positioned at the front end portion in the space between the sealing material 18 and the lid 21, and the sealing material 18 located in front of the distribution space R2 can be eliminated as much as possible. Therefore, since the distribution space R2 is covered from three directions as described above, it is possible to reliably prevent the contents from flowing into the space between the sealing material 18 and the lid 21.

Although one embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and the configuration is changed, combined, or deleted without departing from the gist of the present invention. Etc. are also included.
For example, in the above-described embodiment, in order to rotate the main plate portion 44 around the hinge portion 43, the operation portion 47a arranged behind the hinge portion 43 is pulled up, but the main plate portion 44 is larger than the hinge portion 43. The portion arranged in front may be pushed down.
The cup container 1 with a lid does not have to include an overcap 61, a locking portion 28b, and a locked portion 47b. The broken portion 42 may be arranged at a position facing the central portion of the sealing material 18 in the vertical direction.
