Abstract
The utility model relates to a sterilized sampling bag. The sterilized sampling bag comprises a bag body formed by performing heat-sealing on side edges and bottom sides of a front surface and a back surface; each of the front surface and the back surface adopts a three-layer structural composite material by heat sealing and compositing; a sealing strip is arranged inside a bag opening, is embedded inside the bag opening and is thermally integrally fused with the internal surface of a bag body; the sealing strip is formed by a groove and a convex strip corresponding to the groove; the sealing strip is arranged into two groups in parallel; an opening pull cover is arranged outside the bag opening and a plastic belt of which the edge is connected with the side edge of the outer surface of the bag body in a thermal fusing mode; a plurality of pasting points are arranged between the opening pull cover and the outer surface of the bag opening and are used for pasting partial area of the opening pull cover with the outer surface of the bag opening; gaps for allowing fingers to extend are remained among the pasting points; the bag opening is provided with a disposable tearing sealing strip. The sterilized sampling bag can ensure that primitiveness of samples is kept in the sampling, storing and preserving processes, and no secondary pollution exists after evidence obtaining and legal loopholes are avoided to the greatest content.
Description
Technical field
The utility model relates to a kind of aseptic sampling sampler bag, especially refers to a kind of ensure sample collection, accumulating, keeping process maintenance " primitiveness ", avoids to greatest extent the microbial contamination of material evidence sampling management process, chemical pollution; Avoid to greatest extent the aseptic sampling sampler bag of legal loophole, be mainly used in: all kinds of detections, monitoring, check, inspection, law enforcement agency, to food, medicine, cosmetics, health products etc., divide sample, on-the-spot sealing, sample homogeneous mixed processing etc. to its product, half-blank, material evidence, raw MAT'L, material equal samples aseptic collection, sampling accumulating, blind check.
Background technology
At present, the sealing bag detecting for the food and medicine quality monitoring sampling bag that sell in market is mostly the imported products such as the U.S., Germany.The instrument of aseptic sampling, sealing bag kind is few, price is high, poor sealing performance, easily pollute, operation inconvenience.Especially the existing domestic aseptic oversampling envelope product of existing market, its aseptic performance, structure all cannot guarantee the requirements for quality of the aseptic sampling of its high standard.Even also very easily cause outside contamination air intake as import wire type pulls open after sealing is wound around, generally do not have the operator of too many experience to be difficult to avoid operation to put in place, also easier contaminated sample of transportation, obscures the legal liability of sample contamination midway, and fairness cannot actv. guarantee.
Existing market import or domestic aseptic (sampling) mostly sampler bag have following defect:
1, sealing is tight not, and sample is very easily contaminated.Because mostly sampler bag sealing can not with the isolation of outside contamination source, can not guarantee completely and air no touch, the article in sterile bag also can be easy to external leakage in not timing of position as liquid type.The fervent formula melting sealing in edge, sealing intensity is very poor.
2, pollution leak link is more, designs not rigorous.External packing mostly is a hundreds of bag and is mixed in a case, and repeatedly unpacking his sack is caused to people is that external contamination is inevitable; Sealing can not seal by actv., tears the perforation of embossing vestige bilateral with extraneous ventilative; When hand is got sampler bag, can directly contact sealing, can cause direct residual contaminants pollute sealing and easily bring in sample.During use, need at top sealing part, pull open sack with hand, make sampling process can not accomplish integral asepsis operation.
3, individual layer PE material, the non-constant of mechanical strength.Easily cause transportation, sample, detect damage, omission, infiltration of each link etc., sample collection quantity, quality cannot be ensured; Easier deformation fracture when especially the sample of excess Temperature (dining food, liquid) samples, actv. is implemented sampling in good time; When aseptic sampling, laboratory sterile working sampling, flame periphery cannot be used especially.
4, aseptic process is simple, or adopts aseptic process hardly.Scarcely adopt sterilization treatment (directly producing in so-called gnotobasis) there is no the aseptic statement of failure-free, even do not have aseptic useful life to promise to undertake explanation, cannot confirm and authenticate the microbiological contamination degree of aseptic sampler bag.Also there is no in addition secondary encapsulation packing, contamination probability is larger.
5, sign sign is unclear lack of standardization, is difficult to directly write, the cross-examination signature on bag matter surface.Because the reasons such as bag matter and printing are difficult to clear sign signature and related information content (easily write time stamp broken bag or cause ink to pollute).
Therefore need a kind of novel asepsis sampler bag badly, can reach better sealing effectiveness, testing sample is polluted after packing sampler bag into again, more easy to operate more durable.
Utility model content
The purpose of this utility model is to provide a kind of aseptic sampling sampler bag, has the function to keeping testing sample " primitiveness ", prevent from being secondary polluted after testing sample from putting into sampler bag simultaneously, and more convenient operation, the advantage that intensity is higher.
For achieving the above object, the utility model adopts following technical scheme:
A kind of aseptic sampling sampler bag, comprise bag body 1, sack 2, wherein, bag body 1 is by positive 11, the back side 12 forms, described positive 11, the back side 12 is at its side, base heat seal sealing, on bag body 1 top, form sack 2, described positive 11, the back side 12 is all used the gluing stack heat-sealing of the composite material of three-decker to be composited, described sack 2 inner sides arrange sealing band 3, described sealing band 3 is embedded on bag body 1 inside face of sack 2 inner sides, and be integrated with bag body 1 inside face hot melt, described sealing band 3 is comprised of a groove 31 and the raised line 32 corresponding with it, described groove 31 and raised line 32 respectively hot melt are embedded in the front 11 of bag body 1, the back side 12 inside face opposite positions.
Wherein, described sealing band 3 is arranged side by side two groups.
Wherein, the front 11 of described bag body 1, the three-decker at the back side 12 are followed successively by PE layer 13, pet layer 14 and PE layer 15.
Wherein, the front 11 of described bag body 1 arranges printed layers 16, and described printed layers 16 is arranged at pet layer 14 outside faces in positive 11 three-deckers, and the described back side 12 is transparent in printing.
Wherein, described printed layers 16 is transparent materials.
Wherein, described sack 2 arranged outside openings help pull a cart 4, described opening helps pull a cart 4 for edge and bag plastic tape that body 1 outside face side hot melt is connected, described opening help pull a cart 4 and sack 2 outside faces between several affixed points 41 are set, described affixed points 41, by opening help pull a cart 4 subregion and sack 2 outside face adhesions, leaves the gap 42 of stretching into for finger between described affixed points 41; The described opening 4 employing PE composite materials of helping pull a cart.
Wherein, described sack 2 arranges disposable tearing type strip of paper used for sealing 5.
Wherein, described bag body 1 four limits arrange the false proof district 6 of micro text, and bag body front 11 arranges essential information and fills in district 7, encode false-proof district 8, and described bag body 1 outside face carries out corona treatment, and described sampler bag entirety all adopts 8---13K gamma ray sterilization treatment.
The beneficial effects of the utility model:
