Abstract
The utility model provides a one-way exhaust food bag which comprises a bag body and a one-way exhaust hole, the bag body comprises an upper bag body and a lower bag body, each bag body comprises an inner layer, a middle layer and an outer layer, the upper bag body is connected with the lower bag body in a sealed mode, and the one-way exhaust hole is fixed on the surface of the upper bag body in a sealed mode. The one-way exhaust food bag enables gas produced in the package bag to be exhausted in a one-way mode, and effectively prevents the phenomena of bag swelling and breaking.
Description
Technical field
The utility model relates to the packaging for foodstuff field, a kind of specifically exhaust food bag.
Background technology
Present packaging for foodstuff field, general packaging for foodstuff requires long shelf-life, so just needs the packaging bag preferably of packaging bag leakproofness.But after packing was finished, coffee bean can produce gas automatically in the transportation such as coffee bean, if can not in time emit, can differently cause the phenomenon of the bag broken bag that rises, and caused the handling loss cost of idleness.
Conventional at present method for exhausting is to make a call to a breather hole on sack, but extraneous air is to contain a large amount of bacteriums, after in a single day outside air enters food bag, food very easily addles, goes bad, food in the bag also might spill from the breather hole of sack, cause the loss of cost again, increased handling loss, solve this difficult problem so be badly in need of a kind of packaging for foodstuff plastic bag of unidirectional exhaust.
The utility model content
The technical problems to be solved in the utility model is to overcome existing defective, and a kind of unidirectional exhaust food bag is provided, and the gas unidirectional that produces in the packaging bag is got rid of, and bag broken bag phenomenon effectively prevents to rise.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of unidirectional exhaust food bag comprises bag and one-way vent, and described bag comprises upper bag body and lower bag body, and bag includes internal layer, middle level, skin; Described upper bag body is connected with lower bag body is airtight; The airtight upper bag body surface that is fixed on of described one-way vent.
Further, described bag includes three layers, and internal layer is the CPP bag, and the middle level is the PET bag, and skin is the PE bag.
Further, described upper bag body scalds airtight the connection by pressing with lower bag body.
Further, described one-way vent is a center of circle one-way vent.
A kind of unidirectional exhaust food bag of the utility model has following advantage:
1, owing on plastic packaging bag, is provided with one-way exhaust valve, the packaging bag of filling goods is in the process of stacking, gas in the bag can be discharged smoothly, be in addition under the action of gravity of the residual air goods in the packaging bag of top in the bag of bottom and discharge from one-way exhaust valve, can improve the stability of stacking, increase stacking height.
2, improved the impact resistance of plastic packaging bag, when the packaging bag of filling goods in carrying or when eminence is fallen, the air in the bag can be discharged from one-way exhaust valve, reduces the shock wave of the interior residual air generation of bag, reduces or avoids consequent bale broken.
3, one-way exhaust valve can also avoid outside air to enter in the bag, prevents the oxidized contamination and deterioration of inner package.Be mainly used in the unidirectional flexible packagings that appear gas of needs such as packaging bag storage bag, freshness protection package.
4, the difference of this one-way exhaust valve and other products is, this one-way exhaust valve has filtering net and can completely cut off powder body material and the influence of blow off valve is had in the packaging bag of allowing gas simultaneously discharge and do not allow in the packing solid (comprising dust) go out simultaneously, guarantees that again outside air can't enter in the bag.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and constitutes the part of specification sheets, is used from explanation the utility model with embodiment one of the present utility model, does not constitute restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of unidirectional exhaust food bag of the utility model;
Fig. 2 is the structural representation of bag in a kind of unidirectional exhaust food bag of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
A kind of as shown in Figure 1 and Figure 2 unidirectional exhaust food bag comprises bag 1 and one-way vent 2, and described bag 1 comprises upper bag body 11 and lower bag body 12, and bag 1 includes internal layer 13, middle level 14, outer 15; Described upper bag body 11 and 12 airtight connections of lower bag body; Described one-way vent 2 airtight upper bag body 11 surfaces that are fixed on; Described bag 1 includes three layers, and internal layer 13 is the CPP bag, and middle level 14 is the PET bag, and outer 15 is the PE bag; Described upper bag body 11 scalds airtight the connection by pressing with lower bag body 12; Described one-way vent 2 is a center of circle one-way vent.
A kind of unidirectional exhaust food bag of the utility model has following advantage:
1, owing on plastic packaging bag, is provided with one-way exhaust valve, the packaging bag of filling goods is in the process of stacking, gas in the bag can be discharged smoothly, be in addition under the action of gravity of the residual air goods in the packaging bag of top in the bag of bottom and discharge from one-way exhaust valve, can improve the stability of stacking, increase stacking height.
2, improved the impact resistance of plastic packaging bag, when the packaging bag of filling goods in carrying or when eminence is fallen, the air in the bag can be discharged from one-way exhaust valve, reduces the shock wave of the interior residual air generation of bag, reduces or avoids consequent bale broken.
3, one-way exhaust valve can also avoid outside air to enter in the bag, prevents the oxidized contamination and deterioration of inner package.Be mainly used in the unidirectional flexible packagings that appear gas of needs such as packaging bag storage bag, freshness protection package.
4, the difference of this one-way exhaust valve and other products is, this one-way exhaust valve has filtering net and can completely cut off powder body material and the influence of blow off valve is had in the packaging bag of allowing gas simultaneously discharge and do not allow in the packing solid (comprising dust) go out simultaneously, guarantees that again outside air can't enter in the bag.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
