Embodiment 1

[0021] Embodiment 1: a kind of sample bag, comprises bag body and bag mouth, as figure 1 , 5 As shown, the mouth of the bag is a dotted line seal 4; the bag body contains the first plastic film 2 and the second plastic film 3, the left and right sides of the first plastic film 2 and the second plastic film 3 of the sample bag and The bottom side is a snug fixed connection. A first sealing strip 21 is arranged on the outside of the bag and near the mouth of the bag, the first sealing strip 21 is arranged transversely and is closely fixed to the first plastic film 2; between the first sealing strip 21 and the first plastic film 2 The first metal wire 22 is provided, and the first metal wire 22 is arranged transversely and corresponds to the first sealing strip 21; the second plastic film 3 is respectively provided with a second sealing strip 31 corresponding to the first sealing strip 21 And the second metal wire 32 corresponding to the first metal wire 22, the second sealing ...

Embodiment 2

[0024] Embodiment 2: the only difference between embodiment 2 and embodiment 1 is: a kind of sample bag, such as figure 1 , 2 , 3, the left and right sides of the filter cloth 7 and one side of the first plastic film 2 and the second plastic film 3 are closely fixed to each other; the periphery of the filter cloth 7 and the first plastic film 2 and the second plastic film The peripheries of the two plastic films 3 are closely attached to each other and fixed, and one side is reserved as the mouth of the bag, and the space on both sides of the filter cloth 7 is the storage space 5 and the sampling space 1 of the sample bag. Example 2 is the same as Example 1 for the rest.

Abstract

The invention discloses a sample bag. The sample bag comprises a first sealing strip, a second sealing strip, a first metal wire and a second metal wire. A bag mouth can be conveniently closed or opened by utilizing the components, and the sample bag has the advantages that the sampling is easy, and the storage and carrying are convenient. Pulling lugs are respectively and fixedly arranged at the central positions of the second sealing strip and the first sealing strip, and parts of the pulling lugs are bonded and fixed between the sealing strips and plastic films. As the parts of the pulling lugs can be machined together with the sealing strips and the plastic films, and clung to and fixed with one another, the machining can be completed in one step, and the production cost is further reduced. The sample bag solves the ubiquitous problems of complication in operation and inconvenience in carrying in the prior art, and the production cost is lowered.

Description

technical field [0001] The invention relates to a sample bag. Background technique [0002] The general procedure for detecting solid or liquid substances to be tested is: sampling on site, taking a part of the substance to be tested in a laboratory or testing room after bagging and soaking it in a solution, and measuring the eluate for testing after the chemical substance is fully analyzed. The requirements for sampling bags in the above technologies are relatively high, and the sampling bags must have the advantages of easy sampling, convenient storage and portability. However, the existing sample bags generally have disadvantages such as complicated operation, inconvenient to carry, and high production costs. Contents of the invention [0003] The present invention overcomes the shortcomings in the above-mentioned prior art and provides a sample bag, which has the advantages of easy sampling, convenient storage and portability. [0004] Technical scheme of the present...
