Technical Field

The invention relates to the technical field of packaging, in particular to a rice packaging bag.

Background

The rice is a finished product prepared by the working procedures of cleaning, hulling, milling, finishing and the like of rice, contains nearly 64 percent of nutrient substances in the rice and more than 90 percent of nutrient elements required by a human body, and is a main food for people in most regions of China.

The rice packing bag is developed in the rice packing industry at home and abroad for several years, along with more and more humanization, high requirements, high standards and high pursuits of living standard requirements of people, portable rice bags with the volume of 5kg and 10kg are respectively arranged on the market at present, and the portable rice bags are common vacuumized and common zipper sealing bags are also provided.

The air leakage caused by friction is avoided in the transportation process, the suitable amount of the rice for each time of life of a small family is small, the rice is poured out for a plurality of times, the remaining rice is easy to damp, and the rice is worm-producing or deterioration and taste-changing.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: overcomes the defects of the prior art and provides a moisture-proof rice packing bag.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a wrapping bag of rice, includes inner bag and outer bag, and the top of inner bag is sewed up in the upper portion of outer bag, and the bottom of inner bag is sewed up in the lower part of outer bag, and both all form intermediate layer, its characterized in that at the bottom of outer bag and middle part: a paperboard with the thickness of 1 cm-3 cm is arranged in the interlayer between the outer side of the bottom of the inner bag and the inner side of the bottom of the outer bag.

Further, the shape of the paperboard is the same as that of the bottom of the inner bag.

Further, the thickness of the paperboard is 1.5 cm-2.5 cm.

Furthermore, foam is arranged in the interlayer in the middle part, and dry activated carbon particles are mixed in the foam.

Further, the inner bag and the outer bag are plastic woven bags.

Further, a composite plastic bag is arranged in the inner bag.

Further, a handle is arranged on the part of the upper part of the outer bag, which exceeds the inner bag.

Furthermore, the outer side of the handle is provided with a flexible material.

The invention has the beneficial effects that:

the bottom of the packaging bag is provided with the paper board, so that the bottom is placed on the ground when rice is placed generally, and the arrangement of the paper board can prevent the bag containing the rice inside from directly contacting the ground, so that the probability of the rice being affected with damp is reduced to a certain extent; in addition, a composite plastic bag is arranged in the inner bag for containing rice, and an interlayer arranged between the inner bag and the outer bag is filled with foam and activated carbon particles, so that the rice is further prevented from being affected with damp, and the rice bag can be prevented from being bitten by mice to a certain extent.

FIG. 1 is a schematic structural view of the present embodiment;

in the figure: 1-outer bag, 2-foam, 3-paperboard, 4-inner bag, and 5-handle.

Detailed Description

The invention is further explained with reference to the drawings and the embodiments.

Referring to fig. 1: the utility model provides a wrapping bag of rice, includes inner bag 4 and outer bag 1, and the top of inner bag 4 is sewed up in the upper portion of outer bag 1, and the bottom of inner bag 4 is sewed up in the lower part of outer bag 1, and both all form intermediate layer, its characterized in that at the bottom of outer bag 1 and middle part: a paperboard 3 with the thickness of 1 cm-3 cm is arranged in an interlayer between the outer side of the bottom of the inner bag 4 and the inner side of the bottom of the outer bag 1.

In this embodiment, the bottom of the inner bag 4 is a square structure, so that the paperboard 3 is designed to be a square structure, and a stable rice bag can be placed. The thickness of cardboard 3 designs into 2cm, ensures that the rice in the rice bag can keep away from ground, has reduced the probability that the rice wets to a certain extent, can not too much increase the height of rice bag again to can not too much increase the shared space of rice bag.

The foam 2 is arranged in a middle interlayer formed by the inner bag 4 and the outer bag 1, the foam 2 is mixed with dry active carbon particles, the foam 2 can prevent the rat from biting the food to a certain extent, and the dry active carbon particles are further moisture-proof to a certain extent.

In this embodiment, inner bag 4 and outer bag 1 all adopt the plastic woven sack of plastic weaving, and the plastic woven sack has the packaging method simply, advantage that the price is low, can also print pattern, trade mark, characters bar code etc. on outer bag 1's the outside. In the inner bag 4, a compound plastic bag is also arranged for containing rice. The composite plastic bag is formed by compounding high-barrier materials such as EVOH, PVDC, PET, PA, PE, PP and the like, and the rice packaging bag made of the material has the characteristics of moisture resistance, mildew resistance and good insect prevention effect.

After the composite plastic bag is filled with rice, the composite plastic bag is sealed, the composite plastic bag is placed into the inner bag 4, the upper part of the outer bag 1 is sealed, a handle 5 is arranged on the part, exceeding the inner bag 4, of the upper part of the outer bag 1, and the handle 5 is used for carrying the bag in a hand, so that flexible materials can be arranged on the outer side of the handle 5 to improve the comfort of the hand during carrying the bag; the flexible material can be selected from rubber, silica gel and other materials.

The present invention is not limited to the above embodiments, and various combinations and modifications of the above technical features may be provided for those skilled in the art, and modifications, variations, equivalents, or uses of the structure or method of the present invention in other fields without departing from the spirit and scope of the present invention are included in the protection scope of the present invention.
