PROBLEM TO BE SOLVED: To make an appearance of a container having square cylindrical shape preferably amusing by securely bringing a sealing section of a sliding lid into tight slide contact with an entire inner peripheral surface of a body of the container. SOLUTION: In the pour-out container with a pump 6 having the square cylindrical barrel 2 and the sliding lid 8 fitted into the barrel 2, the sliding lid 8 has a peripheral cylindrical piece 10 having an outer diameter size slightly smaller than that of an inner peripheral surface of the barrel 2 connected via an outer-flange-formed flange piece 11 with an outer peripheral end of a main plate piece 12, and has an upper trumpet-formed cylindrical piece 17 and a lower trumpet-formed cylindrical piece 18 extending from both upper and lower ends of the piece 10 with a diameter expanded to a diameter size slightly larger than that of the inner peripheral surface of the barrel 2 connected. The pieces 17 and 18 are made to be flexible such that wrinkles which occur can be absorbed. Thus, tight fitting and assembly of the sliding lid 8 with the barrel 2 can be reliably and stably attained. |
