[specific embodiment]
A kind of the first embodiment of the anti-tear structure of vacuum compression bag, as depicted in figs. 1 and 2, before compressed bag includes
Face 1, back 2 and intermediate joint face 3, intermediate joint face 3 include the first joint face 31 and the second joint face 32, as shown in Figure 10,
The two sides (X1 sections and X2 sections) of first joint face 31 and the second joint face 32 are respectively one section of 2 two sides with front 1 and below
(Y1 sections with Y2 sections) mutually press, before 1 also mutually pressed, i.e., the first connection with another section of 2 two sides below (Z1 sections with Z2 sections)
The X1 section of 31 two sides of face is pressed together with the Y1 section of 1 two sides of front, the X2 section of 32 two sides of the second joint face and below 2
The Y2 section of two sides presses together, before the Z1 section of 1 two sides and the Z2 section of 2 two sides below press together, compressing
It is provided with the hot wafering 4 for forming front 1 together with 31 hot pressing of the first joint face on two side positions of bag, and is compressing
The same hot wafering 4 formed below 2 together with 32 hot pressing of the second joint face is also equipped on two side positions of bag.
When hot pressing forms above-mentioned hot wafering 4, hot wafering 4 be also possible to be formed simultaneously in front 1 with below 2 two sides
Side.
It as shown in figure 3 or 4, is the intensity and service life that increase stress-bearing capability with further improve compressed bag, hot pressing
Block 4 is arc block, and hot wafering 4 is equipped with the arc convex 40 convex to compressed bag internal direction.
To make the hot wafering 4 of pressing formation more smooth, beautiful, the cavity 41 not pressed is equipped among hot wafering 4.
Front 1, below 2 outer layer be nylon layer and internal layer is PE layers, the first joint face 31 and the second joint face 32
With front 1 and 2 stitching surface is PE layers below and another side is nylon layer.
When using intermediate joint face 3 as the bottom surface of compressed bag, intermediate joint face 3 is set to the bottom of compressed bag, and first connects
2 bottom edge mutually presses with front 1 and below respectively on the bottom edge of junction 31 and the second joint face 32.
When using intermediate joint face 3 as the top surface of compressed bag, intermediate joint face 3 is set to the top of compressed bag, and first connects
Opening 5 is formed between the top margin of junction 31 and the top margin of front 1, the top margin of the second joint face 32 is mutually pressed with below 2 top margin
It closes.
For other embodiments of the invention compared with the first embodiment, difference is only that the hot pressing of other embodiments
Block 4 is square such as shown in fig. 5, or is straight line stick such as shown in Fig. 9, or be such as Fig. 6, Fig. 7 or Fig. 8 institute
The arc stick shown.No matter being all provided with the convex arc of oriented compressed bag internal direction thereon but using the hot wafering of which kind of form 4
Protrusion 40.But it should be noted that the hot wafering 4 formed between front 1 and the first joint face 31 is connect with below 2 with second
The hot wafering 4 formed between face 32 can be identical or not identical.
But no matter which kind of embodiment is used, mutually pressing, the between the first joint face 31 and the two sides of front 1
Mutually mutually pressing formation crosses between pressing and front 1 and the two sides of back 2 between two joint faces 32 and below 2 two sides
Point A, arc convex 40 is by the side border line of the tangent line B of joint A and front 1 or back 2 at an obtuse angle alpha.
The present invention tests the tear-resistant power of hot wafering 4 using following test method: compressed bag being strutted, in sack
A hard plate is placed in inside, and the width of plate is that half of compressed bag bottom surface or top surface width or so (connects with first
The width of junction 31 or the second joint face 32 is suitable), weight is uniformly placed on plate, constantly aggravates the weight of weight, until
Until joint A is torn breakage.The tear-resistant power of hot wafering 4 as shown in table 1 and the corresponding relationship of α are obtained by testing.
The tear-resistant power of 1 hot wafering 4 of table and the corresponding relationship of α
| α (degree) | Tear-resistant power (kilogram) |
| 100 | 26 |
| 110 | 25 |
| 120 | 22 |
| 130 | 20 |
| 135 | 18 |
| 140 | 9 |
| 150 | 8 |
By table 1 it is found that the angle of α is bigger, then its tear-resistant ability is poorer, and when more than 135 degree, tear-resistant
Power can be reduced rapidly, therefore in order to reach preferable anti-tear effect, the preferable implementation method of the present invention is that the control of the angle α exists
In 135 degree.
