Abstract
The utility model discloses a paper-plastic composite packaging bag which comprises an outer packaging bag, wherein an observation mechanism is arranged on the side wall of the outer packaging bag, the observation mechanism comprises four fixed plates fixedly connected to the side wall of the outer packaging bag, fixed rods are fixedly connected to the opposite side walls of the two fixed plates which are positioned on the same horizontal plane together, the side walls of the two fixed rods are connected with a light screen in a sliding mode together, and a transparent plate is embedded in the side wall of the outer packaging bag. The utility model is convenient for people to observe the storage condition in the packaging bag, does not need to frequently open the packaging bag, reduces the contact chance of the grains in the packaging bag with oxygen and moisture, avoids the grains from being affected with damp and deteriorated, and also avoids the direct irradiation of the grains and sunlight.
Description
Technical Field
The utility model relates to the technical field of packaging bags, in particular to a paper-plastic composite packaging bag.
Background
Cereals are one of indispensable foods on dining tables of common people for thousands of years as traditional diets of Chinese people, play an important role in diet of China and are taken as traditional staple food.
The current partial cereal storeroom is placed in the sack, because the sack is opaque, people need regularly examine the storage capacity or the cereal condition in the sack, but oxygen in the air and vapor can get into in the bag when opening, like this many times, can make the interior cereal of bag deteriorate and wet, in order to solve above-mentioned problem, need design a paper and mould compound wrapping bag.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects in the prior art and provides a paper-plastic composite packaging bag.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a compound wrapping bag is moulded to paper, includes outer packing bag, the outer packing bag lateral wall is equipped with observation mechanism, observation mechanism includes four fixed plates of fixed connection at the outer packing bag lateral wall, is located the common fixedly connected with dead lever of the relative lateral wall of two fixed plates of same horizontal plane, two the common sliding connection of dead lever lateral wall has the light screen, the outer packing bag lateral wall inlays and is equipped with the transparent plate.
Preferably, the inner wall of the outer packaging bag is provided with a heat insulation layer, and the inner wall of the heat insulation layer is provided with a waterproof layer.
Preferably, waterproof layer inner wall fixedly connected with magic subsides, sealing strip, the sealing strip is located the top of magic subsides.
Preferably, the side wall of the light screen is respectively and elastically connected with the side walls of the two fixed plates through two springs, and the two springs are respectively sleeved on the side walls of the two fixed rods.
Preferably, the transparent plate is a transparent plastic sheet, and the diameter of the shading plate is larger than that of the transparent plate.
Preferably, the shading plate side wall is fixedly connected with a handle, and the handle side wall is provided with anti-skidding lines.
The utility model has the following beneficial effects:
1. according to the utility model, the light screen is far away from the transparent plate by pulling the handle, so that people can conveniently observe the storage condition in the packaging bag, the packaging bag does not need to be opened frequently, the contact chance of grains with oxygen and moisture in the packaging bag is reduced, the grains are prevented from being damped and deteriorated, and the transparent plate is shielded by the light screen under the elastic action of the spring, so that the grains are prevented from being directly irradiated by sunlight;
2. according to the utility model, the heat insulation layer and the waterproof layer are sequentially arranged on the inner side of the outer packaging bag, so that the influence of external temperature on grains can be prevented, and water vapor can be isolated to prevent the grains from contacting with water.
