Embodiment

Below in conjunction with drawings and Examples the present invention is carried out more detailed explanation.

As depicted in figs. 1 and 2, the present invention is a kind of fruit bag, and its openend bore of this bagging is greater than the bottom bore, and vertical section is inverted isosceles-trapezium-shaped, the end of its openend along on have one the circle passage 1, be provided with take-up device 9 in the passage 1.A kind of typical structure of the present invention is that the openend bore is 100mm, and the bottom bore is 40mm, and the bagging height is 80mm.Another kind of typical structure is that the openend bore is 80mm, and the bottom bore is 30mm, and the bagging height is 60mm.

The working method of take-up device 9 is described below by two embodiment.

Embodiment one
