Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

As shown in fig. 1-3, the utility model provides a multilayer food packaging bag, which comprises an outer bag body 1, wherein the outer bag body 1 is a tear-resistant non-woven fabric layer, which can prevent the packaging bag from being scratched by the outdoor environment and affect the safety of the food stored inside, an inner bag body 2 is arranged in the outer bag body 1, the inner bag body 2 is used for storing the food, a seal 3 is fixedly connected with the top of the outer bag body 1 and the top of the inner bag body 2, the seal 3 can seal the opening of the outer bag body 1 and the opening of the inner bag body 2 and prevent the food from falling from the inner bag body 2, a plurality of connecting blocks 11 are arranged between the outer bag body 1 and the inner bag body 2, the connecting blocks 11 are made of foam materials, which not only can buffer the external pressure, but also can provide buoyancy for the packaging bag, thereby preventing the packaging bag from being difficult to salvage after falling into water, a heating bag 12 is fixedly connected with the inner part of the outer bag body 1, the inside of heating bag 12 is equipped with heating bag 121, heating bag 121 intussuseption is filled with supersaturated sodium acetate solution, still fixedly connected with metal shrapnel in the heating bag 121, because the concentration of supersaturated solution is too high, the state is unstable, when pressing metal shrapnel, produced slight vibrations just are enough to make the solute crystallization, become more stable solid, this process is exothermic, so heating bag 121 just begins to release heat, heat the food in the inner bag body 2, two fixing device 4 of outside fixedly connected with of outer bag body 1.

The outside fixedly connected with aluminium film layer 21 of inner bag body 2, aluminium film layer 21 not only can transmit the heat that heat package 121 released more evenly, can also accelerate heat transfer's speed for the food in the inner bag body 2 is hot faster, the one end and the aluminium film layer 21 fixed connection of connecting block 11, the other end of connecting block 11 and the inner wall fixed connection of the outer bag body 1.

The zipper 13 is arranged on the outer side of the outer bag body 1, the zipper 13 is connected with the interior of the heating bag 12, and the heating bag 121 in the heating bag 12 can be conveniently replaced by arranging the zipper 13.

The fixing device 4 comprises a fixing tube 41, a cavity is arranged in the fixing tube 41, an elastic rope 42 is fixedly connected to the inner wall of one side of the cavity, a first threaded hole is formed in the inner wall of the other side of the cavity, a fixing head 43 is connected to the inner thread of the first threaded hole, a fixing ring 431 is fixedly connected to one end of the fixing head 43, the elastic rope 42 is fixedly connected to the other end of the fixing head 43, a second threaded hole 44 is formed in one end, away from the fixing head 43, of the fixing device 4, a fixing bolt 45 is connected to the inner thread of the second threaded hole 44, the fixing bolt 45 is matched with the fixing ring 431, the fixing bolt 45 is taken out, the fixing head 43 is twisted, the fixing ring 431 is pulled to draw out the elastic rope 42, the elastic rope 42 is wound around the trunk and a tent support, the fixing bolt 45 passes through the fixing ring 431 and then is fixed back to the second threaded hole 44, the packaging bag can be bound to the trunk or the tent support, so that a user does not need to hold the packaging bag with hands when having a meal, a plurality of wrapping bags can be tied up to eat different food simultaneously, promoted user's use and experienced, and when launching in outdoor needs, can tie up the wrapping bag and play the effect that increases buoyancy on user's trick, promote user's security.
