Abstract
The invention relates to a vacuum packaging bag, which includes a bag body; and a vacuum extraction valve is arranged on the plastic bag body. The vacuum packaging bag is characterized in that the vacuum extraction valve includes a bottom valve plate, a switch seat, a switch, and a sealing gasket; the bottom valve plate is connected with the film of the bag body; the switch seat is arranged on the bottom valve plate; the bottom surface of the switch seat is provided with an extraction opening; the sealing gasket is arranged on the extraction opening; and the sealing gasket is provided with a switch which can slide on the switch seat in a reciprocating way. The invention overcomes the defects of prior art, provides a vacuum packaging bag which can avoid air outside the bag from flowing into the vacuum packaging bag reversely, and has the advantages of good vacuumizing and sealing effect, rational structure and convenient use.
Description
[technical field]
The present invention relates to vacuum packaging bag.
[background technology]
At present, much be used on the vacuum packaging bag extraction valve bleed finish after, the air that the vacuum packaging bag external world can occur is by the reverse phenomenon that flow in the vacuum packaging bag of extraction valve, make that so there is air again in evacuated packaging bag, therefore, above-mentioned vacuum packaging bag to vacuumize effect not ideal enough, in order to address the above problem, the inventor has designed this patent.
[summary of the invention]
The present invention has overcome the deficiency of above-mentioned technology, avoids in the reverse inflow vacuum packaging bag of bag outer air the vacuumizing and good sealing effect, rational in infrastructure, easy to use of this packaging bag after a kind of vacuumizing is provided.
For achieving the above object, the present invention has adopted following technical proposal:
A kind of vacuum packaging bag includes bag, is provided with the vacuum suction valve on plastic bag, it is characterized in that described vacuum suction valve includes valve egative film, switch seat, switch, packing seal; The valve egative film is connected with the bag film, and switch seat is arranged on the valve egative film; The switch seat bottom surface is provided with bleeding point, and bleeding point is provided with packing seal, and packing seal is provided with the switch that can slidably reciprocate on switch seat;
Be provided with convex tendon or projection around the aforesaid bleeding point;
Aforesaid switch seat bottom surface is provided with fix shaft, and packing seal is provided with knock hole and is set on the fix shaft;
Two relative vertical edges of aforesaid switch seat are provided with protruding rail, and two relative edges of switch are provided with chute, and the chute of switch entangles protruding rail and slidably;
Aforesaid valve egative film has filtering net, and filtering net is provided with some apertures, and aperture communicates with bleeding point;
Aforesaid bag film is connected with the upper surface of valve egative film.
Compared with prior art, the invention has the beneficial effects as follows: when vacuum-packed bag is bled when finishing, switch is slided to the direction of bleeding point, thereby switch is pushed down packing seal and is blocked bleeding point, ambient atmos can not be entered by bleeding point, vacuum packaging bag keeps vacuum state, and the outer air of bag just can reversely not flow in the bag like this; Therefore, the present invention can not flow into air in the back pkt. that is evacuated, and vacuumizes and the sealing effectiveness ideal.

[specific embodiment]
Be described in further detail below in conjunction with accompanying drawing and embodiments of the present invention:
The present invention is a vacuum packaging bag, includes bag 1, is provided with vacuum suction valve 2 on plastic bag 1, and described vacuum suction valve 2 includes valve egative film 3, switch seat 4, switch 5, packing seal 6; Valve egative film 3 is connected with the bag film, and switch seat 4 is arranged on the valve egative film; The switch seat bottom surface is provided with bleeding point 7, and bleeding point is provided with packing seal 6, and packing seal is provided with the switch 5 that can slidably reciprocate on switch seat.
When vacuum-packed bag need be bled, switch slided to the direction away from bleeding point, and this moment, packing seal did not seal up bleeding point, when bleeding, and the packing seal K/UP, gas is extracted out by the slit between packing seal and the bleeding point; Bleed when finishing when vacuum-packed bag, switch slided to the direction of bleeding point, thus switch push down packing seal and block bleeding point, ambient atmos can not be entered by bleeding point, vacuum packaging bag keeps vacuum state.
Be provided with convex tendon 71 or projection around the bleeding point, make packing seal can closelyr push down bleeding point.
Switch seat 4 bottom surfaces are provided with fix shaft 41, and packing seal 6 is provided with knock hole 61 and is set on the fix shaft, and like this, when switch slidably reciprocated pushing down packing seal, packing seal can not run away by the fix shaft location.
Two relative vertical edges of switch seat 4 are provided with protruding rail 42, and two relative edges of switch 5 are provided with chute 51, and the chute of switch entangles protruding rail and slidably.
Valve egative film 3 has filtering net 8, and filtering net is provided with some apertures, and aperture communicates with bleeding point 7.Filtering net is that the chip for fear of bag 1 object of adorning stops up bleeding point.
The bag film is connected with the upper surface of valve egative film 3.Described valve egative film is shaped as circular plastic slice, and certainly, the valve egative film also can be made by other hard materials.The valve egative film also can be other shapes.
Described seal strip is the nonrigid plastic thin slice, and certainly, seal strip also can have material by other and make.
Described plastic bag 1 is connect by anterior bag piece 11 and back bag piece 12 retained thing mouths and all the other side welds on one side and forms together, and the placing port place is equipped with slide fastener; The inside face of anterior bag piece 11 is a smooth side, and the inside face of back bag piece 12 is a rough surface.The inside face one hot pressing of described back bag piece 12 has a plurality of grooves 13, and air is extracted out along groove when bleeding, and it is easier, thorough to bleed.Described vacuum suction valve 2 is arranged on the anterior bag piece 11.
