Abstract
The utility model discloses a zipper easy to tear and a packaging bag of the zipper. The relative positions of a piece A and a piece B are provided with a male strip and a female groove which are mutually meshed. A bag body is opened from the portion of a tearing strip at one end of the packaging bag. The upper side and the lower side of the tearing strip are provided with strip-shaped protrusions capable of achieving the guide function so that the bag body can be torn easier. Padding is filled from the back face of the zipper, so that the zipper is prevented from being polluted by the padding. The outer side, between the tearing strip and the lower protrusion, of the bag body is provided with a laser groove so that more labor can be saved when the tearing strip is torn and the tearing strip can be torn easily by an old person and a child. The tail end of the tearing strip is strengthened and heat-seal is conducted so that when the tearing strip is torn, the tail end of the tearing strip can still be firmly attached to the bag body, people can not throw the torn tearing strip away at will, a user can use the packaging bag conveniently, and the environment can not be polluted.
Description
Technical field
The utility model relates to plastic wrapping product technical field, specifically a kind of easily tearing chain and packaging bag thereof.
Background technology
Plastic open-close strip is because its quality is light, compliance is good, cheap, can Reusability etc. feature and be widely used in packaging field.Although small and exquisite unremarkable, but follow the pulse of world's packing business closely and fast development.The open-close strip of existing market widespread use is made up of a male pawl and two parts that a female groove separates, edge material and the structure of male pawl and female groove are basic identical, when heat-sealing by male pawl and female groove simultaneously hot pressure arrive the both sides of bag opening, can repeat to open and close sack thereby reach, keep sack content freshness, safety, the excellent results such as the shelf-life of prolongation content.But adopt the packing sack of this common slide fastener to have following shortcoming: the filling of sack top is as liquid, and powder, when the contents such as granule, these contents easily enter in the male pawl and female groove of slide fastener, pollute slide fastener, cause slide fastener closure not tight, the ill effects such as sack gas leakage; Meanwhile, while adopting the filling of sack top, the slide fastener of sack is opened and closed repeatedly, can reduce the intensity of slide fastener.For above-mentioned defect, people improve, and have adopted the mode of loading from sack bottom.But this filling mode is just applicable to the sack of three bandings, for popular in the market Self stand bag and bag with square bottom inapplicable.
Utility model content
In order to overcome above-mentioned defect, the utility model provides a kind of easy tearing chain and packaging bag thereof, tears bar place open bag in packaging bag one end, and tearing the upper and lower both sides of bar has the strip projected parts playing the guiding role, and more easily tears bag.And filling is when content, needn't open slide fastener, male pawl and female groove of double-layered slide fastener are closed together, and content filling is what to complete from the back side of slide fastener, have avoided weighting material pollution slide fastener, have extended the service life of slide fastener.
The technical solution of the utility model is achieved in that scheme one: easily tearing chain is made up of A sheet and two of B sheets, the relative position of A sheet and B sheet is provided with male bar and female groove of a pair of mutual interlock, it is characterized in that, female groove is set on A sheet, the top of A sheet arranges strip projected parts, public bar is set on B sheet, tears bar and be superimposed upon the upper end of B sheet, tear projection that the below of bar is also provided with strip projected parts and A sheet with respect to tearing bar symmetry.
Further, the top and the bottom of the public bar of described B sheet are provided with anti-skidding rib.
Scheme two: easily tearing chain is made up of A sheet and two of B sheets, the relative position of A sheet and B sheet is provided with male bar and female groove of a pair of mutual interlock, it is characterized in that, public bar is set on A sheet, the top of A sheet arranges strip projected parts, female groove is set on B sheet, tears bar and be superimposed upon the upper end of B sheet, tear projection that the below of bar is also provided with strip projected parts and A sheet with respect to tearing bar symmetry.
further,the top and the bottom of the female groove of described A sheet are provided with anti-skidding rib.
In addition, the utility model also provides the packaging bag with easy tearing chain, and the one side heat-sealing of the bossing of A sheet and B sheet or gluing or super sonic are bonded in to structure packaging bag on the bag of outside.Described bag outside of tearing between bar and below projection is provided with a laser trench, makes to tear bar more laborsaving in the time tearing, and old man, child also can tear easily and tear bar very much.
In addition, tear the end (that end of not tearing) of bar and will reinforce heat-seal process, it is better fixed on bag, when tearing when tearing bar, tearing the end of bar still can firmly stay on bag, people just can not abandon the bar of tearing tearing it down conveniently like this, not only facilitated user but also do not polluted the environment.
The beneficial effects of the utility model are: when 1, this slide fastener is heat sealed to the opening both sides of sack, by twice of traditional heat-sealing, bring up to current only heat-sealing once, thereby simplify operating process, save the energy, improved capacity rating, because only scalded the slide fastener of a face, thereby save heat-sealable material, saved cost; 2, on a lateral edges of double-layered slide fastener, tear bar, when content, needn't open slide fastener in filling, thereby solved the male pawl of slide fastener and the series of problems such as female groove is contaminated, and this kind of mode loaded and be applicable to various types of bags; The bag outside of tearing 3, between bar and below projection is provided with a laser trench, makes to tear bar more laborsaving in the time tearing, and old man, child also can tear easily and tear bar very much; 4, the end of tearing bar has carried out reinforcing heat-seal process, it is better fixed on bag, when tearing when tearing bar, tearing the end of bar still can firmly stay on bag, people just can not abandon the bar of tearing tearing it down conveniently like this, not only facilitated user but also do not polluted the environment.
