Abstract
The utility model relates to an embedded plastic film one-way valve. The utility model is characterized in that the utility model is provided with an upper valve sheet and a lower valve sheet which have the same shapes and sizes, are adjacent in parallel and are connected through a closed passage; more than two elongated closed passages which trend along two end openings of the upper valve sheet and the lower valve sheet are connected between the upper valve sheet and the lower valve sheet; a material passage surrounded by the upper valve sheet, the lower valve sheet and the closed passage is arranged between the upper valve sheet and the lower valve sheet. The utility model is made into a packaging container bag together with a plastic film bag; liquid, colloid, paste and drying material can be conveniently filled without using a hot melt sealing machine, and the backflow of filled material can be prevented.
Description
The utility model belongs to the packing technique field, particularly is applied to plastic film packaging bag.
At present, to carry out heat sealing behind the plastic film packaging bag can material, this not only will acquire heat sealing equipment, and this production process is often because when can, material is easy to remain in the plastic bag sealing place and comes in contact contact scar, cause the heat fusion that seals not firm, thereby encapsulant is shed or leak.
The purpose of this utility model is to manufacture and design embedded plastic film check valve, seals and wants heat sealing equipment to overcome present plastic film packaging bag can material, and make easily and seal the not firm shortcoming of heat fusion.
The purpose of this utility model reaches like this: a kind of embedded plastic film check valve is characterized in that: have shape and size identical and parallel press close to pass through last valve block 1 and the lower disc 2 that sealing road 4 interlinks; Link between last valve block 1 and the lower disc 2 two long and narrow sealing roads 4 with two port trends of valve block on the upper edge 1 and lower disc 2 are arranged; The material channel 3 that has one or more to be surrounded between last valve block 1 and the lower disc 2 by last valve block 1, lower disc 2 and sealing road 4.
Adopt the utility model of above measure, can make the packing container bag with plastic film bag, composite plastic film bag, paper-plastic composite film bag and other multiple compound membrane bags, filling liquid, colloid, body of paste and dry material easily, the heat sealing machine needn't be used, and the refluence of can material can be prevented effectively.
In conjunction with the accompanying drawings the utility model is described in further detail again below:
Accompanying drawing 1 is the utility model (embodiment one's) a front view;
Accompanying drawing 2 is birds-eye vieies of the utility model (embodiment one);
Accompanying drawing 3 is back views of the utility model (embodiment one);
Accompanying drawing 4 is front views of the utility model embodiment two;
Accompanying drawing 5 is birds-eye vieies of the utility model embodiment two;
Accompanying drawing 6 is back views of the utility model embodiment two;
Accompanying drawing 7 is running condition figure of the present utility model.
With reference to above accompanying drawing.The utility model integral body is made with plastic sheeting, and the shape of last valve block 1 and lower disc 2 and size are identical and parallel to each otherly press close to, and they interlink by long and narrow sealing road 4.Link the sealing road 4 that has more than two between last valve 1 and the lower disc 2, sealing road 4 trends are two ports along last valve block 1 and lower disc 2, and the spacing between the sealing road 4 promptly is the width of material channel 3.The material channel 3 that one or more is arranged between last valve block 1 and the lower disc 2, material channel 3 are surrounded by the parallel last valve block of pressing close to 1, lower disc 2 and sealing road 4.To go up valve block 1, lower disc 2 stacks, and makes their partly mutually hot melts or paste and promptly form one or more material channel 3.Last valve block 1 can be a straight line with the sealing road 4 that part became of lower disc 2 mutual hot melts or stickup, also can be a curve.Accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3 have provided the concrete structure of this real new embodiment one.This embodiment has 3, two sealing roads 4 of a material channel, and last valve block 1 and lower disc 2 all are rectangle, wide about 4 centimetres, be about 10 centimetres, material channel is wide about 2 centimetres, width 2 millimeter in sealing road 4 can cooperate various bag films to carry out a can powdery or a shape material.Accompanying drawing 4, attached 5 and accompanying drawing 6 provided the utility model example and executed two concrete structure, this embodiment has two material channels 3, sealing road 4 is paniculate curves, relatively more suitable bag film enclosing liquid, colloid or the body of paste material of cooperating.Accompanying drawing 7 provides running condition of the present utility model: with exit end embedding plastic film packaging bag of the present utility model or below the composite plastic film packing bag sealing line position, arrival end places on the position of packaging bag enclosing line becomes an integral sealing with packaging bag heat fusion or stickup, and will stay the filling exit that communicates with material channel 3.After material was filled to packaging bag, the pressure that is subjected to interior material of packaging bag and air owing to surface of going up valve block 1 and lower disc 2 of the present utility model was closed, thereby has prevented from effectively to be flow backwards by the material of can.The width in the utility model sealing road 4 can be in two millimeter, and processing way eaily is a heat fusion.
