The sealing rubber strip 4 is composed of an upper rubber strip 7 and a lower rubber strip 10. The two ends of the upper rubber strip 7 and the lower rubber strip 10 are fixedly connected. The lower edge of the strip 10 is fixedly connected with the upper edge of the barrel body 6, the lower edge of the upper rubber strip 7 is a concave portion, and the upper edge of the lower rubber strip 10 is a convex portion; a slide lock head 3 is placed between the convex portion and the concave portion.

Zipper head 3 is made up of cutter 9 and main body 8, and main body 8 both sides is the frame shape of opening, and main body 8 middle part is provided with splitting post 12, and main body 8 front part is provided with front hole 11, and cutter 9 is placed in front hole 11.

Installation method and working process of the present utility model are as follows:

The plastic film 5 is bonded to the inner side of the packaging barrel corresponding to the sealing strip 4 by heat sealing before the barrel lid composite film 2 is heat-sealed with the barrel lid side wall 1 .

A pressable cutter 9 is housed in the front hole 11 of the zipper head 3. Before being pressed, the knife point of the cutter 9 is not exposed from the inner side of the zipper head 3. Expose and puncture the plastic film 5. When the zipper head 3 is pulled, the tip of the knife cuts the plastic film 5 along the moving track of the zipper head 3. After the zipper head 3 moves along the sealing strip 4 for one week, the packaging barrel can be Open the lid to access the contents of the barrel.

When it is necessary to reseal the packaging barrel, the zipper head 3 can be pulled back along the sealing strip 4 in reverse, and the concave part of the upper rubber strip 7 and the convex part of the lower rubber strip 10 in the sealing rubber strip 4 will be squeezed and buckled by the zipper head 3. Connect, so as to realize the resealing of the packaging barrel.

The beneficial effect of the utility model is that after the packaging barrel is opened for the first time, the sealing rubber strip can still be pressed by pulling the zipper to achieve the purpose of sealing again.
