  However, in the above-described conventional cup container with a lid, there is a problem that the liquid content that scatters when the sealing member is broken easily adheres to a finger or the like. That is, when the sealing member is broken at the cutting edge part, the internal solution may be ejected from the broken part of the sealing member. However, in the above-described conventional cup container with a lid, a pressing part is formed on the upper surface of the cutting edge part. In addition, since the finger or the like is arranged at a position immediately above the fractured portion of the seal member, the internal solution that has jumped out from the fractured portion of the seal member is likely to adhere to the finger or the like.

  The present invention has been made in consideration of the above-mentioned conventional problems, and provides a cup container with a lid that prevents the scattered internal solution from adhering to a finger or the like when the internal solution is scattered when the seal member is broken. It is an object.

The cup container with a lid according to the present invention includes a cup body in which an inner solution is accommodated and an opening portion opened upward is sealed by a seal member, and a lid body attached to an upper end portion of the cup body In the cup container with a lid, the lid body has a pressing portion disposed above the seal member with a gap, and has a shape bulging downward from a shape bulging upward. A reversible portion that can be reversed and deformed, and a cutting blade portion that is connected to the reversing portion and breaks the seal member to open the cup body. The cutting blade portion is located above the seal member. In the plan view perpendicular to the central axis of the cup body, the cutting blade portion is disposed close to the outer edge side of the lid in the plan view. And the pressing portion extends from the central axis to the cutting edge portion. Disposed eccentrically to the position, the reversing section, while being continuously to the pressing portion, toward the side opposite to the cutting edge portion side relative to the said pressing portion in the plan view, downward an inclined wall portion inclined Te, of the inclined wall portion, an end portion opposite to the cutting edge portion side with respect to the said pressing portion in the plan view is, between the center axis of the lid It is characterized in that it is disposed on the opposite side to the pressing portion side.

  With such a feature, when the pressing portion is pushed down with a finger or the like, the reversing portion is reversed from the shape bulging upward to the shape bulging downward. Thereby, the cutting blade part connected with the reversing part moves downward (seal member side) with the reversing operation of the reversing part downward, and the sealing member is broken by the cutting blade part. At this time, since the cutting blade portion is disposed at a position shifted from the pressing portion in plan view, a finger or the like that presses down the pressing portion is disposed at a position away from the breakage portion of the seal member.

Further , the separation distance between the pressing portion and the cutting blade portion is shortened, and when the pressing portion is pressed down to move the cutting blade portion downward, the force for pressing down the pressing portion is easily transmitted to the cutting blade portion.

  According to the lid-equipped cup container of the present invention, since the finger or the like that pushes down the pressing portion is disposed at a position away from the breakage point of the seal member, the inner solution splashes when the seal member breaks. The internal solution is less likely to adhere to the finger or the like. Thereby, a finger | toe etc. can be prevented from becoming dirty at the time of opening a cup container with a lid.
