Description
Technical field
The utility model relates to a kind of valve bag for packing powder or granular material, belongs to packaging bag production field.
Background technology
Valve bag is the packaging bag of current international popular, it comprises bag and valve port cylinder, be provided with two the trapezoidal mouth pieces and two rectangle mouth pieces that are folded to form by the sack of bag, and by two trapezoidal mouth pieces and two rectangle mouth pieces mutually overlap adhesive seal to form bag at the bottom of and bag top, wherein two trapezoidal mouth pieces are all positioned at above rectangle mouth piece, described valve port cylinder inserts in bag from the trapezoidal mouth piece on bag top and the gap of rectangle mouth piece, and the upper and lower surface of valve port cylinder is adhesively fixed with corresponding trapezoidal mouth piece and rectangle mouth piece respectively.
When valve bag is used for filling powder or granular material, due to the particularity of filling material, need at valve bag bag inside suit one deck plastic bag, plastic bag opening flushes with valve bag bag top, and during filling material, material enters in the plastic bag of bag from valve port cylinder, the distance stretching into bag due to valve port cylinder is shorter, material is easy to fill with in the interlayer of plastic bag and bag, and breakage at the bottom of easily causing bag, affects packaging quality.
Utility model content
The purpose of this utility model is just for above-mentioned the deficiencies in the prior art, a kind of valve bag of anti-filling interlayer is provided, when it is for filling powdery or granular material, can prevents material from pouring in the interlayer of plastic bag and valve bag bag, effectively improve packaging quality.
To achieve these goals, the technical solution adopted in the utility model is such:
A kind of valve bag of anti-filling interlayer, comprise bag and valve port cylinder, be provided with two the trapezoidal mouth pieces and two rectangle mouth pieces that are folded to form by the sack of bag, and by two trapezoidal mouth pieces and two rectangle mouth pieces mutually overlap to form bag at the bottom of and bag top, wherein two trapezoidal mouth pieces are all positioned at above rectangle mouth piece, the mouth piece adhesive seal at the bag end, the mouth piece adhesive seal of the side of valve port cylinder is not inserted on bag top, valve port cylinder inserts in bag from the gap of the unencapsulated trapezoidal mouth piece of bag top opposite side and rectangle mouth piece, described bag inside suit one deck plastic bag, plastic bag opening flushes with valve bag bag top, the rectangle mouth piece on described bag top connects extension sealing member along bag center, valve port cylinder discharge end stretches out extension seal ends, valve port cylinder feed end position is positioned at the connection lead place that rectangle mouth piece is connected with bag side, the upper and lower surface of valve port cylinder respectively with corresponding trapezoidal mouth piece, rectangle mouth piece and extension sealing member are adhesively fixed.
Preferably, at the bottom of above-mentioned bag and outside bag top, bond one deck reinforcement paper, at the bottom of can strengthening bag and the intensity on bag top, improve the quality of package valve pocket.
Compared with prior art, the utility model stablizes by increasing extension sealing member prolongation valve port cylinder the distance stretched in bag, thus enable valve port cylinder stretch into plastic bag, effectively avoid because valve port cylinder stretches into the generation of the situation falling into the interlayer of plastic bag and bag apart from short material, effective raising filling quality, the position of valve port cylinder feed end is arranged at the connection lead place that rectangle mouth piece is connected with bag side simultaneously, such valve port cylinder also can not stretch out outside bag, the situation of bag outside is positioned at compared with valve port cylinder feed end, because valve port cylinder is just on bag, in use, in transportation, valve port cylinder of the present utility model is not easy to be damaged, filling complete after, close valve port cylinder feed end, so also further increase the packaging quality of the utility model valve bag.
