PURPOSE: To connect a lid part with a pouring part in the opened state, and position the lid part at a predetermined position against the pouring part. CONSTITUTION: This closure unit 10 comprises a pouring part 11 and a lid part 12 for opening and closing a pouring mouth of the pouring part 11, and has an area consisting of at least two materials with at least one different property. The pouring part 11 and the lid part 12 are pivotably connected by a hinge 14. The hinge 14 is formed into at least one bearing part formed in the pouring part 11 and the lid part 12, and has a pivotably mounted pivot part corresponding to the bearing part. When the pouring mouth is closed by the lid part 12, the lid part 12 can be positioned at the pouring part 11. Since the bearing part is made of a material and the pivot part is made of another material, and the contacting faces between the bearing part and the pivot part are formed with good precision, no gap is formed between both parts. |
