Description

A pullable protective soil sample collection bag

technical field

The utility model relates to the field of sample collection devices, in particular to a pullable protective soil sample collection bag.

Background technique

At present, soil samples need to be collected in fields and industrial pollution sites such as coking in soil pollution investigations. Generally, the determination of physical and chemical properties and heavy metal soils uses ordinary plastic bags to take samples. The process has the following shortcomings:

1. The inner and outer labels of ordinary plastic bags, the outer label is easily contaminated and damaged due to friction and the inner label is easily affected by microorganisms and moisture due to poor sealing, resulting in inaccurate reading of information;

2. The information on the outside of the ordinary plastic bag marked with a marker pen during transportation often fades due to unprotected, unpackaged, easy contact and friction, or moisture caused by improper storage;

3. Ordinary plastic bags do not have collision protection devices. When the samples are transported in large quantities, the plastic bags have the risk of wear and tear, resulting in the loss of samples;

4. Ordinary plastic bags have no lifting device, which is inconvenient to carry;

5. When collecting contaminated soil from coking, petrochemical and other sites, the use of ordinary plastic bags may have its own dissolution effect and affect the organic pollutant components of soil samples.

SUMMARY OF THE INVENTION

In view of this, the purpose of the present invention is to provide a protective soil sample collection bag that can be pulled up, which aims to overcome the problem of inconvenient storage of existing soil samples.

In order to achieve the above-mentioned purpose of the utility model, the technical solutions adopted are as follows:

A pullable protective soil sample collection bag, which sequentially includes an inner layer bag, a middle layer bag and a protective layer from the inside to the outside, and the middle layer bag is respectively connected with the inner layer bag and the protective layer through an adhesive or thermoplastic;

The bottom surface of the inner layer bag is an inwardly foldable bottom surface, which can be folded inward into four layers. The bag mouth of the inner layer bag is provided with a self-sealing strip for sealing the inner layer bag, and the inner side wall of the inner layer bag is provided. There is a self-sealing pouch on it, and the upper end of the self-sealing pouch is provided with a self-sealing opening that can be opened and closed;

The middle layer bag includes a bag body with a bag opening at the upper end and two ropes made of PE material. The outer upper part of the middle layer bag is provided with a label bag, and the label bag contains two sheets of label information paper. A self-sealing pouch put into the inner bag is used as an inner label, and the remaining label is still put back into the label bag as an outer label; the position of the middle bag body close to the edge of the bag mouth is symmetrically arranged along the bag mouth. There are two opening channels, the two opening ropes are overlapped and arranged in the two opening channels, and the bag opening can be closed by pulling the two opening ropes, and it is convenient to carry;

The protective layer includes a protective layer main body, and the protective layer main body includes a plurality of air column bags arranged in the circumferential direction of the middle layer bag, and the wrapping of the air column bags can ensure the originality and safety of the sample. An inflation channel is arranged in the middle of the air column bag, and an inflation nozzle is fixed at the upper end of the inflation channel. Slow down the external impact, thus protecting the interior, and also play a certain role in thermal insulation.

Preferably, a metal film is attached to the inner side of the inner bag for collecting organic contaminated soil samples.

Preferably, the self-sealing strip is a concave-convex buckle self-sealing strip, and the concave-convex buckle self-sealing strip includes a concave strip and a convex strip, and the concave strip and the convex strip are matched and arranged on the inner side of the inner bag mouth.

Preferably, the protective layer further includes a protective cap, the protective cap is composed of several air column bags, and the protective cap and the main body of the protective layer can be connected by a plurality of connecting buttons. When there are many soil samples collected, The collection bag can be protected as a whole by installing a protective cap.

More preferably, the connecting button includes a male snap button and a female snap button matched with the male snap button, the male snap button is arranged on the protective cap, and the female snap button is arranged on the protective layer main body and is connected with the protective layer. Male snaps are set relative to each other.

Preferably, the inner layer bag, the middle layer bag and the protective layer are all made of PE material.

The beneficial effects of the present utility model are:

1. The label bag contains two sheets of label information paper. After completing the labeling of the sample label information, one of them is put into the self-sealing pouch of the inner bag as an inner label, and the self-sealing pouch is sealed to avoid the inner label due to direct contact with soil. The possibility of damage ensures the integrity of the label and information; the remaining label is still put back into the label bag as an external standard, which is convenient for operators to directly obtain sample information.

2. The protective layer does not need to be inflated when not in use or without protection. The air column bag swollen up when protection is required has a certain impact resistance and protects the soil samples (including bottled samples) in it. Since there is no gas channel between the interconnected air column bags, if the air leakage of the single-cut air column bag occurs, it will not affect other air column bags and the collection bag as a whole.

3. The upper end of the middle-layer bag is provided with an extractable opening rope, which can not only play the role of closing the opening, but also facilitate the carrying of the collection bag.

4. The collection bag is made of PE material, which is pollution-free, tear-resistant and durable for soil samples without special requirements.

5. Good airtightness ensures the original state of soil samples, avoids contamination, does not need to carry special ropes and packaging bags, and reduces the burden on operators.

6. When collecting organic contaminated soil samples, use an organic sampling bag with a metal film (such as aluminum foil, etc.) on the inner layer to prevent the effect of the self-dissolution effect of the plastic bag on the organic pollutant components of the soil sample.
