The present invention relates to the spontaneous heating packaging bag of a kind of field, comprise bag front and bag reverse side that top and bottom close respectively; Feature is: the both sides of described bag front and bag reverse side to arrange in first insert edge in insert edge and second, and in bag front, bag reverse side, first, in insert edge and second, insert edge surrounds in the inner chamber formed and places calcium oxide; In described first, in insert edge and second, the outside of insert edge arranges the first outer insert edge and the second outer insert edge respectively, and the bottom of the first outer insert edge and the second outer insert edge, top, sidepiece close respectively; In described second outer insert edge and second, insert edge surrounds in the cavity formed and places tap water, and in the first outer insert edge and first, insert edge surrounds in the cavity formed and places food to be heated.The present invention is easy to carry, and heated food does not need by means of other equipment.

Description

Field spontaneous heating packaging bag

Technical field

The present invention relates to a kind of packaging bag, the spontaneous heating packaging bag of especially a kind of field, belongs to field of packaging material.

Background technology

Nowadays, people's life stress is larger, in Holiday, most people can choose other places tourism, encamp or even explore, but many visitors select this kind of movable time, usually preparing solid food such as biscuit, bread, instant noodles etc. does not need the food that heats.But ready food is due to bad heating in the wild in advance at home for some, and people are just difficult to have reeky savoury spread out of doors.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, provide the spontaneous heating packaging bag of a kind of field, easy to carry, heated food does not need by means of other equipment.

According to technical scheme provided by the invention, the spontaneous heating packaging bag of a kind of field, comprises bag front and bag reverse side, and top and the bottom of bag front and bag reverse side close respectively, and the bottom closure place of bag front and bag reverse side forms underseal limit; Feature is: the both sides of described bag front and bag reverse side to arrange in first insert edge in insert edge and second respectively, and in bag front, bag reverse side, first, in insert edge and second, insert edge surrounds in the inner chamber formed and places calcium oxide; In described first, in insert edge and second, the outside of insert edge arranges the first outer insert edge and the second outer insert edge respectively, the bottom of the first outer insert edge and the second outer insert edge closes with underseal limit respectively, in the top and first of the first outer insert edge and the second outer insert edge, in insert edge and second, the top of insert edge closes, the sidepiece of the first outer insert edge and the second outer insert edge respectively with first in the sidepiece of insert edge is closed in insert edge and second forms side sealing; In described second outer insert edge and second, insert edge surrounds in the cavity formed and places tap water, and in the first outer insert edge and first, insert edge surrounds in the cavity formed and places food to be heated.

Described bag front, bag reverse side, the first outer insert edge and the second outer insert edge are followed successively by the first biaxially oriented laminated polyester film, the first adhesive for polyurethane layer, aluminium foil, the second adhesive for polyurethane layer and the first curtain coating layer of polypropylene foil from outside to inside.

In described first, in insert edge and second, insert edge is followed successively by the second curtain coating layer of polypropylene foil, the 3rd polyurethane adhesive adhensive layer, the second biaxially oriented laminated polyester film, the 4th adhesive for polyurethane layer, aluminium foil, the 5th adhesive for polyurethane layer and the 3rd cast polypropylene film layer from outside to inside.

The present invention has the following advantages: the present invention is by the bag of employing three inner bag compositions, tap water is put in the inner bag of left side, calcium oxide is put in middle bag, the food that need heat is put in right bag, only left side insert edge need be poked two apertures during use, treat bag and calcium oxide exothermic heat of reaction wherein in tap water inflow, the food in the bag of heating right side.This sack is easy to carry, and heated food does not need by means of other equipment.

Detailed description of the invention

Below in conjunction with concrete accompanying drawing, the invention will be further described.

As shown in FIG. 1 to 3: the spontaneous heating packaging bag of described field comprises bag front 1, bag reverse side 2, first outer insert edge 3, insert edge 4 in first, second outer insert edge 5, insert edge 6 in second, underseal limit 7, side sealing 8, first biaxially oriented laminated polyester film 9, first adhesive for polyurethane layer 10, aluminium foil 11, second adhesive for polyurethane layer 12, first curtain coating layer of polypropylene foil 13, second curtain coating layer of polypropylene foil 14, 3rd polyurethane adhesive adhensive layer 15, second biaxially oriented laminated polyester film 16, 4th adhesive for polyurethane layer 17, aluminium foil 18, 5th adhesive for polyurethane layer 19, 3rd cast polypropylene film layer 20 etc.

As shown in Figure 1, the present invention includes bag front 1 and bag reverse side 2, top and the bottom of bag front 1 and bag reverse side 2 close respectively, the bottom closure place of bag front 1 and bag reverse side 2 forms underseal limit 7, the both sides of bag front 1 and bag reverse side 2 to arrange in first insert edge 6 in insert edge 4 and second respectively, and in bag front 1, bag reverse side 2, first, in insert edge 4 and second, insert edge 6 surrounds in the inner chamber formed and places calcium oxide; In described first, in insert edge 4 and second, the outside of insert edge 6 arranges the first outer insert edge 3 and the second outer insert edge 5 respectively, the bottom of the first outer insert edge 3 and the second outer insert edge 5 closes with underseal limit 7 respectively, in the top and first of the first outer insert edge 3 and the second outer insert edge 5, in insert edge 4 and second, the top of insert edge 6 closes, the sidepiece of the first outer insert edge 3 and the second outer insert edge 5 respectively with first in the sidepiece of insert edge 6 is closed in insert edge 4 and second forms side sealing 8; In described second outer insert edge 5 and second, insert edge 6 surrounds the cavity that formed for placing tap water, and in the first outer insert edge 3 and first, insert edge 4 surrounds the cavity of formation for placing food to be heated.
