Aqua type content corrosion prevention packing aerosol jar
Technical field: the utility model relates to a kind of packing container, and especially a kind of aqua type content corrosion prevention packing aerosol jar can be used for the aqua type aerosol products tin-plate aerosol jar anti-corrosion is packed.
Background technology: at present in aerosol products packing technique field, common employing tin-plate material is made the aerosol jar, this kind aerosol jar is in oil base organic solvent aerosol push agent and finish pharmaceutical products system, because content is the oil base organic substance, tank body internal corrosion reflection to irony is not too strong, and generally coating common antifretting coating on the iron flask inwall can solve content to tank body anti-corrosion problem.But in aqua type content soup system,, the irony tank body is represented extremely strong because this content soup is to be the content on groundwork basis with water.Adopt traditional anti-corrosion technology to keep, cause aerosol jar push agent to leak, the quality problems that the soup spray is not come out less than the some months time both corrosion failure.Development along with society; environmental protection; the protection consciousness of people's life and health requires more and more strong; contain the aerosol products that organic solvent is the push agent composition; have that the smell is awful, to the atmospheric ozone damage layer, people and animals are had stimulation, environmental pollution, serious problems such as inflammable and explosive; the customer represents that difficulty accepts, is expecting that later-model aerosol products comes out, and solves many shortcomings of existing market sell goods.So, how to solve the technical matters of aqua type composition content to tin-plate matter aerosol jar corrosion failure, be to concern the key issue of successfully developing aqua type aerosol products aerosol jar corrosion prevention packing technique.
Summary of the invention: at above-mentioned the deficiencies in the prior art, the utility model provides a kind of aqua type content corrosion prevention packing aerosol jar, water base property content and iron flask inwall are isolated, thereby reach, water base property content spins the corrosion purpose to can aerosol jar.
For achieving the above object, the technical solution adopted in the utility model is: aqua type content corrosion prevention packing aerosol jar comprises tank body, liquid storing bag, hydraulic pipe and spray valve.Liquid storing bag is placed in tank inner chamber, and hydraulic pipe one end stretches in the liquid storing bag, and the other end is positioned at outside the liquid storing bag and with the spray valve bottom and is connected, and spray valve and tank body mouth end are combined closely and be sealing state, and liquid storing bag itself is also made the sealing shape.Be full of pressurized air between inner tank wall and the liquid storing bag.
Thereby the utility model makes water base property content and tank body isolation avoid being corroded and bore a hole.Simultaneously, the liquid storing bag that PVC material or foil laminated film material are made is nontoxic, non-stimulated, anti-soup chemical reaction, effectively prolong the packing and storing time limit, and simple in structure, easy operating, the utility model technology, the push agent (fluorine Lyons, the third butane blue gas) of utilizing pressurized air to substitute the conventional aerosol product does not contain and fires composition, and is safe in utilization, the environmental protection close friend.Can be widely used in the iron flask packing of traditional oil base aerosol is used for the iron flask packing of the water base aerosol products of Development and Production, save the energy, reduce greenhouse gas emission.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the structural representation that liquid storing bag combines with spray valve.
Accompanying drawing 3 is the scheme of installation of each assembly of the utility model.
In the accompanying drawing: 1 is liquid storing bag, and 2 is hydraulic pipe, and 3 is spray valve, and 6 is tank body, and 7 is pressurized air.
Now further specify in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, aqua type content corrosion prevention packing aerosol jar comprises tank body 6, liquid storing bag 1, hydraulic pipe 2 and spray valve 3.Liquid storing bag 1 is placed in tank body 6 inner chambers, hydraulic pipe 2 one ends stretch in the liquid storing bag 1, the other end is positioned at outside the liquid storing bag 1 and with spray valve 3 and is connected, 6 jars of tight-lipped close combinations of spray valve 3 and tank body are sealing state, liquid storing bag 1 itself is also made the sealing shape, size is similar with tank body 6 cavity volume, make its thickness, pressure, volume meets national measurement standard, hydraulic pipe 2 diameter of bores are 2MM, external diameter is 4MM, make with PVC plastic material or foil laminated film material, spray valve 3 middle part through holes are provided with valve rod 30 and link to each other with the aerosol can, hydraulic pipe 2 and valve bottom connection pipe 30 leak-tight joints.
As shown in figures 1 and 3, during installation, with liquid storing bag 1, hydraulic pipe 2, spray valve 3 assembles, then with liquid storing bag 1 flat being involved in the tank body 6, tank body 6 inner chambers are inflated, make between tank body 6 inwalls and the liquid storing bag 1 and be full of pressurized air 7, close spray valve 3 simultaneously in 6 jars of mouths of tank body, pressurized air 7 can not leaked, throw soup in the liquid storing bag 1 storage through 30 superchargings of valve lever endoporus with filling Medicinal liquid devices again, liquid storing bag 1 expansion this moment, reduce a jar compressed air space, produce the pressure that presets, when valve rod 30 switches of pushing spray valve 3, pressurized air extruding liquid storing bag 1 in jar and with soup through valve rod 30, shower nozzle ejection atomizing.
