To provide a vessel capable of simply decreasing the volume of rubbish etc.

The vessel to store objects such as rubbish etc. is composed of an storage part having an opening and a lid to block the opening, whose part where the lid is attached is formed approximately cylindrically, while the lid is made of a material having flexibility and repulsiveness to a bending force and formed with a dimension larger than the radially directed dimension of the opening, in which the storage part or the lid is formed as a slip preventive part in the part where the storage part and the lid contact with each other when the lid is attached to the storage part. According to this constitution, a bulky object such as a plastic vessel packing (exterior film, lap, tray, sack for snack, etc.) is retained at the opening of the storage part owing to the lid making deformation convexly downward with its flexibility and repulsiveness when the lid is depressed downward at the time of the lid being attached to the storage part, and it is possible to compress the stored object and decrease its volume.
