Summary of the invention
First technical matters to be solved by this invention is that use is torn in packaging bag of the prior art for ease; Sealing band need be set, the seal limit also has tearing port; Second technical matters that the present invention will solve simultaneously is that packaging bag of the prior art is had relatively high expectations for the accuracy rate that is provided with of tearing port; In case be provided with unreasonablely, will cause destroying after the application of force problem of tearing port, and then provide a kind of and need not to be provided with tearing port and promptly can be easy to open and packaging bag with low cost.
For realizing above-mentioned purpose, the invention provides a kind of tearable mouth packaging bag, comprise the packaging bag body, said packaging bag body is carried out leak free tooled joint limit; Independently control flange for two that outside the tooled joint limit of said at least one side, extend the setting of wrong position, the said two-layer flange of controlling has the zone of coincidence.
Extension is provided with two-layer extension edge outside the tooled joint limit of said at least one side, and further elongation moulding has the said flange of controlling on every layer of said extension edge.
The said flange of controlling is an arc.
Each said flange vertex of controlling flange shifts to install.
Said coincidence zone is said at least 1/3 of the flange length of controlling.
Two flange vertexs of controlling flange are symmetrical set with the intersection point place longitudinal axis of two said flanges.
Each said flange and said this body by integral forming of packaging bag of controlling.
Tearable mouth packaging bag of the present invention has following advantage with respect to prior art:
First; Tearable mouth packaging bag of the present invention; Comprise the packaging bag body, the packaging bag body is carried out leak free tooled joint limit; Also outside the tooled joint limit of at least one side, extend with respect to prior art packaging bag of the present invention and to be provided with the two-layer flange of controlling that shifts to install, provide the user when the application of force is carried out in packaging bag, conveniently to pinch the application of force place that handle is held like this; The present invention also further defines the two-layer flange of controlling and has the zone of coincidence; Preferred said coincidence zone is said at least 1/3 of the flange length of controlling; Force in when controlling flange as the user like this; Can strength be concentrated on and overlap the zone, thereby strength further concentrated on the said regional corresponding tooled joint place that overlaps tooled joint is torn, and then packaging bag is opened through being applied to the power of controlling on the flange.Packaging bag of the present invention need not to be provided with tearing port with respect to prior art, promptly can with packaging bag easily the application of force open, make simple and with low cost simultaneously.
The second, tearable mouth packaging bag of the present invention, extension is equipped with two-layer extension edge outside the tooled joint limit of said at least one side, and further elongation moulding has the said flange of controlling on every layer of said extension edge.That is to say; Extension edge is the extendible portion of packaging bag body; Control flange and then extend and be arranged on the extension edge, further like this guaranteed that the user forces in when controlling flange, extension edge that can the strength passage area is bigger further acts on the tooled joint limit; Thereby the tooled joint limit is stably torn, avoid causing packaging bag application of force place to damage after the application of force.
