Preservation box

The utility model relates to a preservation box. Mainly, a hollow air hole column and an annular sheet body of an elastic film are arranged; when a user covers the containing box body with the sealingcover, the sealing cover can be tightly attached to the inner side of the top end of the containing box body through upward folding of the annular sheet body of the elastic film, and therefore air originally existing in the containing box body can be exhausted through the air hole column at the bottom of the groove. Therefore, a nearly vacuum closed space is formed in the containing box body, andfood or food materials stored in the containing box body can be prevented from making direct contact with air so as to achieve the long-time fresh-keeping effect. 本实用新型为一种保鲜盒，主要是通过中空的透气孔柱及弹性薄膜的环形片体的设置，以便使用者将密封盖盖设于容置盒体上方时，可以通过弹性薄膜的环形片体向上翻折来紧密贴合于容置盒体顶端内侧，以便将原本存在于容置盒体内部的空气经由凹槽底部的透气孔柱排出；进而使得容置盒体内部形成一近乎真空的密闭空间，存放于容置盒体内部的食物或食材可以阻绝与空气的直接接触来达到长时间的保鲜效果。
