Abstract
A kind of long-term folding sealing packaging bag of permanent seal cooling, including foldable bag body, seal is provided with foldable bag body, be provided with described foldable bag body two it is longitudinal folding while and it is at least one laterally folded while, it is laterally folded while and it is longitudinal folding while inner or outer side covered with inflection shape vertical bar.The present invention in packaging bag by increasing inflection shape vertical bar and/or inflection shape end angle, high polymer material can be reduced or eliminated and produce internal stress at the position folded for a long time, packaging bag material of main part is avoided to keep the sealing of sealing bags because folding stress and cracked defect.
Description
Technical field
The present invention relates to a kind of folding sealing packaging bag, category sealing protection packing technique field is more particularly to a kind of durable
The long-term folding sealing packaging bag of type.
Background technology
Folding sealing packaging bag is through folding by a planar body, and is sealed by seal and is formed, general folding
Formula sealing bags are packaged with content in a state of use, and the material of main part of sealing bags is in expansion shape under this state
State, the performance of the material of main part of packaging bag meet requirement.To save space, packaging bag is also deposited with the pattern of folding sometimes
Put, for storing, packing frequency of use and the less sealing bags of usage time with folded form for a long time, if material of main part
For the macromolecule materials such as rubber, plastics when, the folding part bit length phase internal stress effect under, material of main part is also easy to produce folding stress
Caused aging crackle, the sealing of sealing bags is caused to decline or even fail.At present, temporarily without the correlation for taking counter-measure
Patent.
The content of the invention
The problem to be solved in the present invention is：Under conditions of material property is not changed, by increasing inflection shape vertical bar or returning
Shape end angle is rolled over, high polymer material is reduced or eliminated and is folding internal stress caused by position for a long time, so as to avoid the occurrence of crack defect,
The sealing of retainer body material.
The object of the present invention is achieved like this：A kind of long-term folding sealing packaging bag of permanent seal cooling, including foldable bag body,
Seal is provided with foldable bag body, two longitudinal folding sides and at least one laterally folding are provided with described foldable bag body
Folded side, it is laterally folded while and it is longitudinal folding while inner or outer side covered with inflection shape vertical bar.
It is laterally folded while with it is longitudinal folding while intersection covered with inflection shape end angle.
The width of inflection shape vertical bar is the 10%-20% of foldable bag body width.
Inflection shape vertical bar top is arc chord angle.
A kind of long-term folding sealing packaging bag of permanent seal cooling, including foldable bag body, seal is provided with foldable bag body,
Be provided with described foldable bag body two it is longitudinal folding while and it is at least one laterally folded while, laterally folded side with longitudinal direction roll over
The inner or outer side of folded side intersection is covered with inflection shape end angle.
Described inflection shape end angle be expansion after be quadrangle or circle or ellipse.
The long-term folding sealing packaging bag of permanent seal cooling provided by the invention has the advantages that：
By increasing inflection shape vertical bar and/or inflection shape end angle in packaging bag, high polymer material can be reduced or eliminated long-term
The position of folding produces internal stress, avoids packaging bag material of main part from keeping packing because folding stress and cracked defect
The sealing of bag.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the partial structural diagram that the present invention installs inflection shape vertical bar additional.
Fig. 2,3 are inflection shape vertical bar structural representations of the invention.
Fig. 4,5,6 are the inflection shape end corner structure schematic diagrames of the present invention.
Fig. 7 is the package construction schematic diagram using inflection shape vertical bar and inflection shape end angle.
Fig. 8 is the package construction schematic diagram using inflection shape end angle.
In figure：1st, foldable bag body, 2, seal, 3, laterally folded side, 4, longitudinal folding side, 5, inflection shape vertical bar, 6, return
Roll over shape end angle.
Embodiment
Folding sealing packaging bag is through folding by a planar body, and is sealed by seal and is formed, and seal 2 is adopted
With slide fastener or other sealing strips；Content is placed in foldable bag body 1, and foldable bag body 1 is foldable according to actual conditions, can also
Open and flat mode is deposited.
Embodiment 1：
As shown in Figure 4：A kind of long-term folding sealing packaging bag of permanent seal cooling, including foldable bag body 1, are set on foldable bag body 1
Have seal 2, be provided with described foldable bag body 1 two it is longitudinal folding while 4 and it is at least one laterally folded while 3, in transverse direction
The inner or outer side on folded edge 3 and longitudinal folding side 4 is covered with inflection shape vertical bar 5.All portions folded for a long time of sealing bags
Position has installed folding stack structure i.e. inflection shape vertical bar 5 additional, folding stack structure again with the plane film tape as packaging bag material of main part
Bonding forms a complete sealing bags.
Embodiment 2：
As shown in figure 5, be that one kind of embodiment 1 is simplified, a kind of long-term folding sealing packaging bag of permanent seal cooling, including foldable bag
Body 1, seal 2 is provided with foldable bag body 1, two longitudinal folding sides 4 and at least one are provided with described foldable bag body 1
Individual laterally folded side 3, it is laterally folded while 3 with it is longitudinal folding while 4 intersections inner or outer side covered with inflection shape end angle 6.
All positions folded for a long time of sealing bags have installed folding stack structure i.e. inflection shape end angle additional, folding stack structure again with as bag
The plane film tape of pack material of main part is bonded to form a complete sealing bags.
Embodiment 3：
The present invention is new also can to install inflection shape vertical bar 5 and inflection shape end angle 6 additional simultaneously in packaging bag, play the effect of enhancing.
In above-described embodiment, the width of inflection shape vertical bar 5 is the 10%-20% of the width of foldable bag body 1, and inflection shape vertical bar 5 pushes up
Hold as circular arc, as shown in Figure 2,3, 4；The top of inflection shape end angle 6 is also circular arc, to be quadrangle or circle or ellipse after expansion
Shape.
In the preparation, inflection shape vertical bar 5 and inflection shape end angle 6 can vulcanize the present invention with foldable bag body global formation or burst
Afterwards with foldable bag body bonding forming.
