In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions:

A vacuum packaging bag, comprising a plastic bag body, on which a vacuum pumping valve is arranged, is characterized in that a cover sheet is connected to the top of the opening end of the plastic bag body, and the cover sheet is provided with a connecting edge and a movable edge, and the connecting edge Connected to the plastic bag body, the movable side forms an opening with the upper side of the plastic bag body, and a fastening device capable of sealing the opening is arranged between the movable side and the plastic bag body.

A vacuum packaging bag as described above is characterized in that the plastic bag body includes a front bag sheet and a rear bag sheet.

A vacuum packaging bag as described above is characterized in that a part of the upper edge of the front pocket sheet forms an opening with the movable edge of the cover sheet, and another part of the upper edge of the front pocket sheet and the rear pocket sheet are connected with the connecting edge of the cover sheet.

A vacuum packaging bag as described above is characterized in that the front pocket sheet and the movable edge of the cover sheet form an opening, and the back pocket sheet is connected with the connecting edge of the cover sheet.

A vacuum packaging bag as described above is characterized in that a part of the upper edge of the front pocket sheet and the rear pocket sheet forms an opening with the movable edge of the cover sheet, and another part of the upper edge of the rear pocket sheet is connected with the connecting edge of the cover sheet.

A vacuum packaging bag as described above is characterized in that the plastic bag body further includes a connecting bottom sheet connected between the bottom end of the front bag sheet and the rear bag sheet.

A vacuum packaging bag as described above is characterized in that the plastic bag body is square.

A vacuum packaging bag as described above is characterized in that the fastening device is composed of a groove arranged on the cover sheet and a raised strip arranged on the plastic bag body and capable of being inserted into the groove.

Compared with the prior art, the present invention has the following advantages: since a cover is provided on the top of the bag body, when the operator puts the quilt into the bag body, the bag body will not be caused by expansion of the quilt after it is put in. The opening cannot be closed, and it is simpler and more labor-saving to close the opening. In addition, the opening of the bag body can be set according to the size of the quilt. The vacuum bag can also be used in combination with a box such as a non-woven box to protect the vacuum bag and prolong its service life.

【Detailed ways】

The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

As shown in Figure 1-8; a vacuum packaging bag, including a bag body 1, a vacuum pumping valve 2 is provided on the bag body 1, and a cover sheet 3 is connected to the top of the opening end of the bag body 1, and the cover sheet 3 is provided with Connecting edge 31 and movable edge 32, connecting edge 31 is connected on the bag body 1, and the top of movable edge 32 and bag body 1 forms opening 4, is provided with opening 4 and can be sealed between movable edge 32 and bag body 1. The fastening device 5 ; the bag body 1 includes a front pocket sheet 11 and a rear pocket sheet 12 .

Embodiment 1: As shown in Figures 1-6; a part of the top of the front pocket sheet 11 and the movable edge 32 of the cover sheet 3 form an opening 4, and another part of the top of the front pocket sheet 11 and the back pocket sheet 12 and the cover sheet 3 The connecting edges 31 are connected.

Embodiment 2: As shown in Figures 7 and 8 ; the front pocket 11 and the movable edge 32 of the cover 3 form an opening 4 , and the rear pocket 12 is connected to the connecting edge 31 of the cover 3 .

Embodiment 3: A part of the upper side of the front pocket 11 and the rear pocket 12 forms an opening 4 with the movable edge 32 of the cover 3 , and another part of the upper side of the rear pocket 12 is connected with the connecting edge 31 of the cover 3 .

Embodiment 4: As shown in FIG. 9 ; the above-mentioned vacuum bag can also be used in combination with a hard box.

As shown in Figures 4-8; the bag body 1 also includes a connecting bottom sheet 13 connected between the bottom end of the front pocket sheet 11 and the rear pocket sheet 12; the bag body 1 is in a square shape.

The fastening device 5 is composed of a groove 51 arranged on the cover sheet 3 and a raised strip 52 arranged on the plastic bag body 1 and capable of being inserted into the groove 51 .

Since the top of the opening end of the bag body 1 is connected with the cover sheet 3, when the operator puts the quilt into the bag body, the bag body 1 will not cause the opening 4 to be unable to be closed due to the expansion of the quilt after the quilt is put in, and the opening will be closed 4. It is simpler, more labor-saving and faster. In addition, the opening of the bag body can be set according to the size of the quilt. The vacuum bag can also be used in combination with a box such as a non-woven box to protect the vacuum bag and prolong its service life.
