Abstract

The utility model provides a packaging bag used for packaging testing paper sheets for coliform groups. The packaging bag is an aluminum foil packaging bag, the four circumference edges of which are formed into sealing openings, wherein, the lower end of one sealing opening is provided with a plastic slot buckle type inner zipper, and a small distance used as a tearing opening is arranged between the bottom end of the sealing edge and the plastic slot buckle type inner zipper. When the testing paper sheets for the coliform groups are required for carrying out tests, the aluminum foil packaging bag is torn (or sheared) on the tearing opening firstly, the plastic slot buckle type inner zipper is opened, the testing paper sheets for the coliform groups can be taken out for carrying out sampling, then a plastic bag provided with sampled paper sheets is arranged into the aluminum foil packaging bag, the zipper is pressed and sealed well, and the cultivation and the result observation are carried out. The cross contamination of the sampled paper sheets and the micro organism in environment in the process of carrying and cultivation can be avoided by the utility model, and the sanitation and the accuracy of the testing result can be ensured.

Description

A kind of encapsulation bag that is used to encapsulate the coliform test scraps of paper

Technical field

The utility model relates to a kind of packaging system that is used to encapsulate the coliform test scraps of paper.

Background technology

The check of coliform is one of microorganism routine inspection project, and paper disk method has characteristics easily and fast, uses wider.The method that adopts is that the scraps of paper that contain nutrition and specific reaction substrate are sampled, and cultivates the back and observes its growth and characteristic reaction.The check coliform test scraps of paper, are put in the Aluminium Foil Package pack Yi Bian method is that the coliform test scraps of paper are loaded in the packing inner bag of opening with Aluminium Foil Package pack encapsulation again at present, then Aluminium Foil Package are packed four banding mouths.During use,, in the packing inner bag, take out the coliform test scraps of paper,, take back laboratory cultures then with putting back to again in the Aluminium Foil Package pack after this scraps of paper sampling one side the operator cuts off sealing of Aluminium Foil Package pack.Because the sack of the In Aluminium Foil Packing sack cut off and packing inner bag opens wide, carry with incubation in easily and the microorganisms cross pollution in the environment, cause the result inaccurate and have a hygienic issues.

Summary of the invention

To be that design is a kind of encapsulate easy and can prevent the encapsulation bag that is used to encapsulate the coliform test scraps of paper of cross pollution the purpose of this utility model, to avoid the existing problem of existing coliform test scraps of paper encapsulation bagging apparatus.

The technical solution of the utility model is, adopt a kind of Aluminium Foil Package pack with the encapsulation coliform test scraps of paper, the surrounding of this packaging bag forms pressurizing window, wherein the lower end of sealing on one side is provided with slide fastener in the plastic channel button, leaves a bit of distance as tearing notch between the slide fastener in this seals bottom, limit and plastic channel button.

Said tearing notch segment distance is generally 0.1～5.0cm.

When need are tested with the coliform test scraps of paper, tear earlier (or cutting) at port tearing position and open the Aluminium Foil Package pack, open slide fastener in the plastic channel button, can take out the coliform test scraps of paper samples, the polybag that the scraps of paper of having sampled will be housed is then put the Aluminium Foil Package pack into, the good slide fastener of press seal is cultivated and observations.

The utility model is owing to installed slide fastener in the plastic channel button additional in packaging bag, sealed after making the scraps of paper after the sampling reload packaging bag, thereby avoid carry with incubation in environment in the microorganisms cross pollution, can guarantee health and assay accurately.

Description of drawings

Fig. 1 is the structural representation of this coliform test scraps of paper encapsulation bag;

Fig. 2 is the A-A cut-open view of Fig. 1, that is to say zipper synoptic diagram in the plastic channel button.

Embodiment

As shown in Figure 1,1 is the Aluminium Foil Package pack that is packaged with the coliform test scraps of paper of the present utility model, limit 2 is sealed on four limits of packaging bag, its top is sealed and is the sack limit, seal at the distance sack that the 1cm place is provided with slide fastener 3 in the plastic channel button under the limit, its structure as shown in Figure 2, slide fastener and sack seal the part reserved between the place, the limit tearing notch section 4 for this encapsulation bag in the plastic channel button.

Claims

1. encapsulation bag that is used to encapsulate the coliform test scraps of paper, be a kind of Aluminium Foil Package pack, the surrounding of this packaging bag forms pressurizing window, it is characterized in that the lower end of wherein sealing is provided with slide fastener (3) in the plastic channel button, leaves a bit of distance as tearing notch between the slide fastener on one side in this seals bottom, limit and plastic channel button.。

2. encapsulation bag according to claim 1, the distance that it is characterized in that said tearing notch section is 0.1～5.0cm.
