Description

Heat-insulation food packaging bag

Technical Field

The utility model relates to a technical field of wrapping bag, in particular to heat preservation food package bag.

Background

At present, more and more packaged foods appear in daily life of people and bring certain convenience to people, but the existing packaging bags only have the function of containing foods, so that the functions are single, the high-quality life style of people cannot be met, particularly in winter, people can be warm and cool when buying breakfast or cakes outside and do not reach the destination, the taste of the breakfast is reduced, and the food packaging bags with the heat preservation function are very necessary to use.

Therefore, it is necessary to develop a heat-insulating food packaging bag which can insulate the food and reduce the possibility that the food will be cooled by heat.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a heat preservation food package bag, it can keep warm to the food of splendid attire to reduce the possibility that food becomes cold by heat.

The above technical purpose of the present invention can be achieved by the following technical solutions:

the utility model provides a heat preservation food package bag, includes compound outer bag and can dismantle the compound inner bag of connecting in compound outer bag, be equipped with heat preservation and buffer layer between compound outer bag and the compound inner bag.

Through adopting above-mentioned technical scheme, in placing compound interior bag with food, because the existence of heat preservation, can make this wrapping bag have the heat preservation effect to can keep warm to the food of splendid attire, and then reduce food by the cold possibility of heat altered, the existence of buffer layer can play the heat preservation effect on the one hand, and on the other hand can play the cushioning effect, when the wrapping bag emptys, the buffer layer can play the cushioning effect, avoids the food in the wrapping bag to produce the rigid shock, thereby has reduced the broken possibility of food.

Further setting: the heat-insulating layer is arranged at the bottom of the composite outer bag and on the side wall of the composite outer bag, and the buffer layers are connected to the bottom of the composite inner bag and on the side wall of the composite inner bag.

By adopting the technical scheme, the heat-insulating layer is arranged at the bottom of the composite outer bag and on the side wall of the composite outer bag, and compared with the case that the heat-insulating layer is only arranged on the side wall of the composite outer bag, the heat-insulating effect of the packaging bag can be further improved; set up the buffer layer on compound inner bag to can make the food in the wrapping bag press close to with the buffer layer more, and then make buffering effect better, and connect the buffer layer on compound inner bag bottom and compound inner bag lateral wall, compare with only setting up the buffer layer on compound inner bag lateral wall, can further improve the buffering effect of this wrapping bag.

Further setting: the buffer layer is a gas column bag layer.

Further setting: the air column bag layer is detachably connected with the composite inner bag.

By adopting the technical scheme, if the air column bag layer is damaged, the composite inner bag is firstly detached from the composite outer bag, the air column bag layer is exposed, and then the damaged air column bag layer is detached from the composite inner bag and replaced by a new air column bag layer, so that the packaging bag can continuously have a buffering effect.

Further setting: the air column bag layer is detachably connected with the composite inner bag through a first magic tape.

By adopting the technical scheme, when the air column bag layer needs to be detached from the composite inner bag, the first magic tape is pulled to separate the air column bag layer from the composite inner bag, so that the detachment of the air column bag layer is completed; when the gas column bag layer and the composite inner bag need to be installed together, the first magic tapes are attached together, so that the purpose of installing the gas column bag layer on the composite inner bag is achieved.

Further setting: the air column bag layer and the composite inner bag are detachably connected through a first snap fastener.

By adopting the technical scheme, when the air column bag layer needs to be disassembled from the composite inner bag, the male buckle and the female buckle of the first letter buckle are separated, so that the air column bag layer is separated from the composite inner bag, and the disassembly of the air column bag layer is completed; when the air column bag layer and the composite inner bag need to be installed together, the male button and the female button on the first letter button are buckled together, so that the aim of installing the air column bag layer on the composite inner bag is fulfilled

Further setting: the composite inner bag and the composite outer bag are detachably connected through a second snap fastener.

By adopting the technical scheme, when the composite inner bag and the composite outer bag are disassembled, the male button and the female button of the second letter button are separated, so that the disassembly of the composite inner bag and the composite outer bag is realized.

Further setting: the heat-insulating layer is detachably connected with the composite outer bag.

Through adopting above-mentioned technical scheme, if the heat preservation effect of heat preservation becomes relatively poor, then can dismantle the compound inner bag from compound outer bag, expose the heat preservation, dismantle the heat preservation from compound outer bag again to change the heat preservation, make this wrapping bag continue to have better heat preservation effect.

Further setting: the heat preservation layer comprises a tin paper layer and a PU sponge layer, and the tin paper layer is arranged on the PU sponge layer.

Through adopting above-mentioned technical scheme, because the PU sponge layer has heat preservation, thermal-insulated characteristic, the plain noodles of tinfoil has fine heat absorptivity, and its matte inlayer also has fine heat preservation effect simultaneously, consequently, combines tinfoil layer and PU sponge layer together as the heat preservation, can make this wrapping bag play the heat preservation effect, can keep warm the food of splendid attire

Further setting: the mouth of the composite inner bag is closed by a magnet.

Through adopting above-mentioned technical scheme, the sack of magnet with compound inner bag is closed to further reduce the thermal loss of food in the wrapping bag, further improved the heat preservation effect of this wrapping bag.

To sum up, the utility model discloses following beneficial effect has:

1. food is placed in the composite inner bag, and the heat preservation layer can ensure that the packaging bag has the heat preservation effect, so that the heat preservation effect can be realized on the contained food, and the possibility that the food is cooled by heat is further reduced;

2. the buffer layer can play a role in heat preservation on one hand and play a role in buffering on the other hand, when the packaging bag is toppled over, the buffer layer can play a role in buffering, rigid impact on food in the packaging bag is avoided, and therefore the possibility of food breakage is reduced;

3. if the heat preservation effect of heat preservation becomes relatively poor, then can dismantle the outer bag of compound inner bag from compound, expose the heat preservation, dismantle the heat preservation from the outer bag of compound again to change the heat preservation, make this wrapping bag continue to have better heat preservation effect.
