Vacuum compression bag with stable placement

Abstract

The invention provides a vacuum compression bag with high strength and stable placement. The vacuum compression bag with high strength and stable placement comprises a front surface, a back surface, abottom surface, a top surface and an exhaust valve. The back surface is in press-fit with the middle section of the two side edges of the front surface. The bottom surface comprises a first bottom surface and a second bottom surface, the bottom edges of the first bottom surface and the second bottom surface are separately in press fit with the bottom edges of the front surface and the back surface, and the two side edges of the first bottom surface and the second bottom surface are separately in press fit with the lower section of the two side edges of the front surface and the back surface.The top surface comprises a first top surface and a second top surface, the upper edge of the second top surface is in press fit with the upper edge of the back surface, an opening is formed between the first top surface and the upper edge of the front surface, a buckling structure for sealing the opening is arranged on the opening, and the two side edges of the first top surface and the second top surface are separately in press fit with the upper sections of the two side edges of the front surface and the back surface. The exhaust valve is arranged on the bag body formed by the front surface, the back surface, the bottom surface and the top surface. The lower sections of the two side edges of the front surface are connected with the lower sections of the two side edges of the back surface, so that the vacuum compression bag is vertically and stably placed.

Description

【Technical field】 [0001] The invention relates to the field of packaging bags, in particular to a stable vacuum compression bag. 【Background technique】 [0002] A traditional plastic vacuum packaging bag comprises: a front pocket sheet and a rear pocket sheet, the edges of the front pocket sheet bottom and the rear pocket sheet bottom are heat-sealed and the front pocket sheet and the rear pocket sheet are formed into a plastic bag Body, a vacuum pumping valve is provided on the plastic bag body, and the unheated part of the upper part of the front bag sheet and the upper part of the back bag sheet is opened to form a split opening; a cover sheet connected with the split opening, the cover sheet includes There are connecting edges and movable edges; the connecting edges of the cover sheet are respectively heat-sealed with the edges of the front pocket sheet and the rear pocket sheet at the opening of the fork; the movable edge forms the upper edge of the front pocket sheet a...

[0002] A traditional plastic vacuum packaging bag comprises: a front pocket sheet and a rear pocket sheet, the edges of the front pocket sheet bottom and the rear pocket sheet bottom are heat-sealed and the front pocket sheet and the rear pocket sheet are formed into a plastic bag Body, a vacuum pumping valve is provided on the plastic bag body, and the unheated part of the upper part of the front bag sheet and the upper part of the back bag sheet is opened to form a split opening; a cover sheet connected with the split opening, the cover sheet includes There are connecting edges and movable edges; the connecting edges of the cover sheet are respectively heat-sealed with the edges of the front pocket sheet and the rear pocket sheet at the opening of the fork; the movable edge forms the upper edge of the front pocket sheet at the opening of the fork Opening, the bottom of which is a sharp bottom or has a Y-shaped fork, so the bottom of this kind of packaging bag is not firm when it is unfolded and used, it is easy to fall over when it is placed vertically, and it cannot be placed stably, so it is not suitable. It is convenient for the storage of individual bulky items, and it will cause inconvenience in the use of vacuum bags. At the same time, due to the concentration of stress, it is easy to tear at the bifurcation point

[0003] Furthermore, it needs to cooperate with a vacuum pump to vacuumize the bag body during its use, so it is very inconvenient to use

And use this vacuum packing bag to also need to buy a vacuum suction pump in addition, its consumption cost is not cheap for the consumer

Furthermore, the process of using a vacuum pump to evacuate is laborious and time-consuming, and the exhaust efficiency of some manual vacuum pumps is too low, especially for some relatively large vacuum bags, the pumping efficiency is lower, and the required longer pumping time
