ABSTRACT:
A container structure includes a lid and a holder. The lid has a through hole having air-permeable troughs having inner and outer openings. The inner and outer openings of adjacent air-permeable troughs are in opposite directions. An elastic plug is fitted within the through holes, and an air-permeable passageway is formed. By providing the air-permeable passageway, high-temperature circular vapors are regulated and vented. Thus, the lid is prevented from being blown open by the vapors. Clip-on pieces and lower ribs are provided on a sealing portion of the lid. Upward bending portions and upper ribs are provided on a marginal frame portion of the holder. The lid is securely fitted onto the holder by mutual restriction of the lower and upper ribs. Pressing the clip-on pieces down will deform the sealing portions, and will free the lower ribs from the restriction of the upper ribs to open the lid quickly.
