Detailed Description

The present invention will be further described with reference to the accompanying drawings 1 to 6 and examples.

The utility model provides a valve port bag convenient to seal, include the bag body 1 and seal the fastener, 1 top of the bag body is equipped with bag mouth 2, the end of bag mouth 2 is equipped with material mouth 3, it includes curved fixed plate 4 and returning face plate 5 to seal the fastener, the top both sides end of fixed plate 4 is coaxial articulated with the bottom both sides end of returning face plate 5, and returning face plate 5 connects the lateral surface at fixed plate 4, fixed plate 4 forms the hoop body 6 that is located bag mouth 2 outside with returning face plate 5, fixed plate 4 is fixed the laminating in the side of bag mouth 2, the lateral surface of fixed plate 4 and the top of returning face plate 5 are equipped with respectively and can form buckle complex first screens portion 7 and second screens portion 8, the buckle cooperation of first screens portion 7 and second screens portion 8 adopts the draw-in groove formula in this embodiment, the fixed roof pressure rubber strip 12 that is equipped with of the medial surface of returning face plate 5, promote the leakproofness when sealing.

The bottom of returning face plate 5 is equipped with extension 9, be convenient for break off the upset portion off with the fingers and thumb so that the upset of returning face plate 5 breaks away from with fixed plate 4 buckle complex state, the medial surface of extension 9 is equipped with card hole 10, the side of the bag body 1 is equipped with can buckle and cooperate in the fixture block 11 of card hole 10, after returning face plate 5 buckle cooperates in fixed plate 4, through turning over a bag mouth 2 make card hole 10 and fixture block 11 form the buckle cooperation with stabilizing bag mouth 2, the medial surface of extension 9 is equipped with spacing portion 13, spacing portion 13 constitutes the top with fixed plate 4 and leans on spacingly, spacing portion 13 is used for limiting the biggest flip angle of returning face plate 5, and the biggest flip angle of returning face plate 5 is 90, have the guard action to material mouth 3, effectively reduce the tearing possibility of material mouth 3 during the ejection of compact, also be convenient for also stabilizing bag mouth 2 when packing simultaneously.
