Abstract
A kind of resistance bacterium venting bottle cap, including lid and resistance bacterium ventail, there are one void areas, resistance bacterium ventail heat-sealing to be fitted in capping in lid and cover entire void area for setting on capping outside lid；Resistance bacterium ventail is formed by three layers of nonwoven layer, grid rubberised layer, perforated film layer gluing.
Description
Technical field
The utility model is related to a kind of tester device, more specifically to a kind of resistance bacterium venting bottle cap.
Background technology
When doing Bioexperiment or biological detection, need to do Bacteria Culture.Most common Bacteria Culture vessel are culture bottles
And culture dish, it is mostly used culture bottle now from security consideration.Germy culture solution is stored in culture bottle, is grown, and is just needed
It to be contacted with oxygen, bottle closes the lid and can influence the breathing of bacterium and cause anoxic；If not lid bottle cap, bacterium is possible to volatilize
To do harm to huamn body in air.The ventilative bottle cap of bacterium can be hindered therefore, it is necessary to develop a kind of.
Invention content
The shortcomings that the purpose of the utility model is to overcome existing products provides a kind of convenient and practical and can to hinder bacterium ventilative
Resistance bacterium venting bottle cap.
In order to achieve the above object, the utility model is achieved through the following technical solutions：
A kind of resistance bacterium venting bottle cap, including lid and resistance bacterium ventail, there are one interstice coverages for setting on capping outside lid
Domain, resistance bacterium ventail heat-sealing are fitted in capping in lid and cover entire void area；The resistance bacterium ventail is by non-woven fabrics
Three layers of layer, grid rubberised layer, perforated film layer gluing form.
The nonwoven layer is high density polyethylene (HDPE) non-woven fabrics.
The film layer and lid same material.
The void area is circle, and the resistance bacterium ventail is circle.
It is several discontinuous air holes/ventilative seam in the void area.
The void area area is the 35%-50% of the outer capping area of lid.
There is the circular hole in 1 millimeter of interval, 1 millimeter of aperture on the perforated film layer by rectangular array proper alignment.
A kind of resistance bacterium venting bottle cap that Pass through above-mentioned technical proposal is realized has the following advantages：
The characteristic that high density polyethylene (HDPE) non-woven fabrics has good dialysis property and blocks water, hinders blood, hindering bacterium, using netted rubber
Layer and perforated film are to ensure that resistance bacterium ventail has gas permeability, while film with lid can seal compound, remove painting from
Glue is compound, so as to improve the combined strength bination and leakproofness of resistance bacterium ventail and lid.Discontinuous air is set as on lid
The intensity of lid itself is effectively ensured in hole.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram at another visual angle of the utility model；
Fig. 3 is the normal section structural schematic diagram of the utility model resistance bacterium ventail.
Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings and embodiments.
A kind of resistance bacterium venting bottle cap, including lid 1 and resistance bacterium ventail 2, there are one round for setting on 1 outer capping of lid
Void area 11, resistance bacterium ventail 2 are circle, and heat-sealing is fitted in capping in lid 1 and covers entire void area 11；Hinder bacterium
Ventail is formed by 23 3 layers of nonwoven layer 21, grid rubberised layer 22, perforated film layer gluing.
Nonwoven layer 21 is high density polyethylene (HDPE) non-woven fabrics.
It is several discontinuous air holes in void area 11.
11 area of void area is the 35% of 1 outer capping area of lid.
Film layer 23 and 1 same material of lid.
There is the circular hole in 1 millimeter of interval, 1 millimeter of aperture on perforated film layer 23 by rectangular array proper alignment.
Actual production the utility model is the film selected with the culture bottle cap same material for needing to seal, by film whole
1 millimeter of the aperture arranged together circular hole, the needle heat at 1 millimeter of interval punctures punches on roller.Again with latticed glue spreader on compounding machine
Be combined with each other through hot-pressing roller in one face gluing of high density polyethylene (HDPE) non-woven fabrics, and with the film that has openning hole, enter back into one group it is cold
But roller is shaped, and formation is the non-woven fabric composite material of reticulated film while for high density polyethylene (HDPE) non-woven fabrics.
Multiple discontinuous air holes are opened in void area above the bottle cap, are possessed while ensureing bottle cap intensity itself
Maximum dialysis area.
Then non-woven fabric composite material be die-cut to need size and shape, with bottle cap same material punching film surface and
Bottle cap is sealed with heat sealing machine or is sealed with High-frequency machine.
The utility model has the advantages that just practical and can to hinder bacterium ventilative.
Above example is used to understand the method and core concept of the present invention, for those skilled in the art,
Under the premise of not departing from the utility model design, any possible change or replacement are carried out, the protection of the utility model is belonged to
Range.
