Description

Technical Field

[0001] The utility model relates to the technical field of fresh-keeping bags, in particular to a high-barrier multifunctional food fresh-keeping bag. Background Art

[0002] Fresh-keeping bags mainly refer to bags made of food preservative film, which are mainly used to preserve vegetables, fruits, grains, cooked food and other foods. They are widely used in daily life. Fresh-keeping bags are divided into polyethylene (PE), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC) and other types according to the production materials. Fresh-keeping bags should be used for refrigerated and frozen foods in refrigerators instead of ordinary plastic bags. The special process and raw materials of fresh-keeping bags or films have good air permeability and fresh-keeping properties, while ordinary plastic bags will cause food to rot and deteriorate after a long time of use, and the purpose of preservation cannot be achieved;

[0003] The food preservation bags on the market have a single function and can only isolate food from the outside air, but do not have heat preservation performance. In addition, a large amount of air remains in the bags, which seriously affects the preservation effect. When carrying or placing food, it is easy to cause food to collide or be squeezed and damaged, which is not conducive to the preservation of food. Therefore, the utility model provides a high-barrier multifunctional food preservation bag to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0017] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0018] See Figures 1 to 4 As shown, a high-barrier multifunctional food preservation bag comprises a folding bag 1 and a storage bag 2 located inside the folding bag 1, wherein the folding bag 1 is a kraft paper bag, and the storage bag 2 is made of PE or PVDC material;

[0019] Specifically, kraft paper is used as packaging material, which is flexible and strong, has high burst resistance, and can withstand large tension and pressure without breaking, thereby ensuring the strength of the folding bag 1. The storage bag 2 made of PE or PVDC material meets food grade requirements, has good flexibility, and can directly place food.

[0020] Furthermore, the bottom and both sides of the folding bag 1 are provided with folds 11, and the inner wall of the folding bag 1 is provided with an aluminum foil heat-insulating cotton layer 12;

[0021] Specifically, the volume of the foldable bag 1 can be reduced along the fold 11, so that the foldable bag 1 is convenient to store and carry, and after the foldable bag 1 is unfolded, it can be placed upright stably.

[0022] Specifically, the aluminum foil thermal insulation wool layer 12 is composed of aluminum foil and an inner layer bonded together, wherein the aluminum foil can effectively block the inside and outside of the folding bag 1, and the inner layer made of rock wool or glass wool can effectively insulate, greatly improving the thermal insulation effect.

[0023] Furthermore, the inner edge of the opening of the foldable bag 1 and the outer edge of the opening of the storage bag 2 are fixedly connected to form an integrated structure;

[0024] Specifically, the foldable bag 1 is opened, and food can be placed in the storage bag 2. The food is suspended in the storage bag 2 to prevent the food from being damaged by impact or squeezing, thereby achieving a good preservation effect.

[0025] Furthermore, a drawstring 3 is fixedly connected to both sides of the outer wall of the opening of the foldable bag 1, and a multi-layer sealing assembly 4 is connected between both sides of the inner wall of the opening of the foldable bag 1, and the sealing assembly 4 includes a clamping strip 41 and a clamping groove 42 that are snap-fitted with each other, and the clamping strip 41 and the clamping groove 42 are respectively fixed to both sides of the inner wall of the opening of the foldable bag 1;

[0026] Specifically, the clamping strip 41 and the clamping slot 42 are fitted with each other in an interference fit manner, which can seal the contact surface, and the double-layer sealing structure can fully prevent the flow of gas inside and outside the storage bag 2, thereby preventing the occurrence of food odor contamination.

[0027] Furthermore, a one-way valve 5 is provided between the folding bag 1 and the storage bag 2;

[0028] Specifically, the input end of the vacuum cylinder or the vacuum pump is plugged into the one-way valve 5, and the storage bag 2 can be vacuumed with the help of the one-way valve 5. After the input end of the vacuum cylinder or the vacuum pump is pulled out, the outside air will not reversely enter the storage bag 2, which can prevent food from contacting with air and extend the shelf life of the food.

[0029] Furthermore, a sealing assembly 6 is provided at a corner of the bottom end of the folding bag 1, and the sealing assembly 6 includes a connecting tube 61 fixedly embedded in the storage bag 2, a connecting strip 62 is fixedly connected to one side of the connecting tube 61, a sealing cover 63 is fixedly connected to the free end of the connecting strip 62, and the connecting tube 61 and the sealing cover 63 are plug-fitted by interference fit;

[0030] Specifically, the connecting strip 62 can prevent the cover 63 from being lost, and after the cover 63 is nested outside the connecting tube 61, it can effectively block the air flow inside and outside the folding bag 1. An air barrier is formed between the folding bag 1 and the storage bag 2, which can prevent the refrigerated food from heating up quickly and improve the preservation effect of the refrigerated food. On the contrary, when refrigerating food, the cover 63 needs to be opened to achieve the purpose of refrigeration.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
