Abstract
The invention relates to a one-way valve doypack which comprises a doypack body (1), a doypack bottom (2), a doypack opening (3) and a cap (4). The doypack body (1) is formed by attaching the periphery of a front piece to the periphery of a rear piece, the front piece and the rear piece are identical in shape, the doypack bottom (2) is of a rectangular structure, the four edges of the doypack bottom (2) are attached to the bottom of the front piece and the bottom of the rear piece, the doypack opening (3) is arranged between the top of the front piece and the top of the rear piece, the cap (4) is disposed outside the doypack opening (3) and is in threaded connection with the doypack opening (3), the doypack opening (3) comprises a doypack opening pipe (3.1), an elastic hemisphere (3.2) is disposed in the doypack opening pipe (3.1), the convex face of the hemisphere (3.2) is downward, and the hemisphere (3.2) is evenly provided with multiple longitudinal cutting seams (3.3) from the center to the periphery. The one-way valve doypack has the advantages that safety is high and quantitative liquid outlet control is good.
Description
Technical field
The present invention relates to a kind of check valve Self stand bag, belong to packing technique field.
Background technology
Traditional easier for the in use easy discharging of bag mouth charging at top of the Self stand bag of depositing liquid, once Self stand bag is overturned, liquid in bag easily spills, cause waste, and when if the liquid in Self stand bag quantitatively need to be poured out, be generally by by the downward-sloping certain angle of Self stand bag, by controlling angle of inclination, control the flow velocity of liquid.This kind of Self stand bag exists safety performance poor, and the controlled poor shortcoming of quantitative liquid-discharging.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of safety performance better, and the controlled good check valve Self stand bag of quantitative liquid-discharging.
The object of the present invention is achieved like this:
A kind of check valve Self stand bag, it comprises a bag body, the bag end, bag mouth and block, described bag body comprises that identical shaped anter and rear panel fitted and formed by surrounding, the described bag end is rectangular configuration, four limits at the described bag end fit in the bottom of anter and rear panel, described bag mouth is arranged between anter and the top of rear panel, described block is arranged at the outside of bag mouth, described block is threaded with bag mouth, described bag mouth comprises that in bag mouth pipe, being provided with one described in bag mouth pipe has elastomeric hemisphere, described hemispheroidal convex surface is downward, described hemispheroidal center evenly offers the cutting seam of many above-below directions towards periphery.
As a kind of preferred, described anter, rear panel and the material at the bag end are complex film, and described complex film comprises the nylon layer of outer field pet layer, interlayer and the PE of internal layer or PP layer from outside to inside successively.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention is because the hemisphere in bag mouth offers cutting seam, hemisphere there is be similar to the function of check valve, when needs feed liquor, liquid is easy to inwardly flow into from hemispheroidal cutting seam, when needs fluid, liquid is not easy outwards to flow out from hemispheroidal cutting seam, needs people by certain strength squeeze bag body, ability fluid.Even if so Self stand bag is overturned, the liquid in bag is not easy to spill, and can not cause waste, and safety performance is better, while needing pouring out liquid in fixed quantify, only needs to control the strength of squeeze bag body, convenient operation, and quantitative liquid-discharging is controlled better.Therefore to have safety performance better for this check valve Self stand bag, and the controlled good advantage of quantitative liquid-discharging.
