A cover-type containing structure for flexible enclosures primarily includes a front cover sheet, a rear cover sheet and a flexible enclosure. The front cover sheet includes a first joining edge and a cover piece, whereas the rear cover sheet includes a cover assembly corresponding to the cover piece. The flexible enclosure includes a second joining edge and by engaging the first joining edge with the second joining edge, the front cover sheet and the flexible enclosure are fixed. Besides, the containing structure further includes a holding portion. Under a contained state, the holding portion is used to contain smaller objectives; whereas, in an unfolded state, in addition to using the flexible enclosure to contain larger objectives, the holding portion can be also used to contain smaller objectives. The present invention can be also applied to a piece of clothing combined with a bag unit or other flexible enclosure.
