Detailed Description
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.
The inflatable sealing aluminum foil bag in the prior art is provided with the one-way valve in the outer side of the aluminum foil bag, and aims to conveniently lead in protective gas to the inside of the aluminum foil bag, but the protective gas escapes after the aluminum foil bag is opened at every time, the aluminum foil bag cannot have the prolonged protection effect on the articles inside the aluminum foil bag when the aluminum foil bag is reused, and sometimes the condition of creating the protective gas is not available under the household environment, and the condition of leading in the protective gas in the aluminum foil bag cannot be used again.
The disclosure is further illustrated with reference to the following examples
Example 1
As shown in fig. 1, 3, 4 and 5, a reusable inflatable sealed aluminum foil bag comprises three film layers, namely a first film layer 1, a second film layer 2 and a third film layer 3;
the edges of the first film layer 1 and the third film layer 3 are attached to form an outer lining of an aluminum foil bag with an opening at the top, the opening at the top can be closed, the second film layer 2 is positioned in the outer lining, the periphery of the second film layer 2 is attached to the inner surface of the outer lining to form an inner lining of the aluminum foil bag, an upper edge line 7 of an attaching surface is positioned in the middle or lower part of the inner surface of the outer lining, the inner surface of the outer lining is divided into a first accommodating cavity and a second accommodating cavity by the second film layer 2, and the opening at the top is positioned at the top of the first accommodating cavity;
the surface of second film layer 2 sets up into check valve 4 and the check valve 5 of giving vent to anger, and the check valve 4 that admits air is located first chamber one side that holds, and the check valve 5 of giving vent to anger is located the second and holds chamber one side.
The mode of pressing outer lining can be for pressing first film layer and third film layer simultaneously or pressing the outer lining that first film layer and third film layer formed with a hand clip because first holding chamber and second hold the chamber and be located both sides and conveniently carry out the nip, and second film layer and third film layer are separated after the second holds the chamber and swells moreover, also can conveniently press outer lining.
One of the first accommodating cavity and the second accommodating cavity is filled with protective gas, the other accommodating cavity is not filled with protective gas, the one-way valve is closed, when the clamping outer liner applies pressure to the side filled with the protective gas, the pressure of the gas of one is increased, the one-way valve is initially opened, and if the two accommodating cavities are in a balanced state without applying external force, the one-way valve is not opened; meanwhile, when one-way valve is opened, the other one-way valve is kept in a closed state due to the pressure of the directional gas, so that the two containing cavities of the gas can be communicated; meanwhile, when the gas on one side is introduced into the other side, the pressure of the newly-charged gas is not enough to resist the pressure of the other clamping pressure gas, so that the two one-way valves cannot be opened simultaneously.
The distance between the air inlet one-way valve 4 and the central point of the second film layer 2 is larger than the distance between the air outlet one-way valve 5 and the central point of the second film layer 2.
The check valve of giving vent to anger is nearer apart from the central point, and the check valve of giving vent to anger is because the bottom that the action of gravity is close the aluminium foil bag, and when the second held the gas flow in chamber and reached first chamber that holds, the protection gas was favorable to the first discharge that holds the air in chamber from the first bottom upwards circulation that holds the chamber.
In the recycling process of the recyclable inflatable sealed aluminum foil bag, the protective gas is gradually reduced along with the increase of the recycling times, and volatile gas of the articles or external air can be mixed into the protective gas along with the increase of the recycling times, but the articles can be effectively protected within the recycling times.
The body outside-in of first thin layer 1 and second thin layer 2 is PET layer 8, aluminium foil layer 9, nylon weaving layer 10, polyethylene curtain coating thin layer 11 in proper order.
The nylon weaving layer can improve the intensity of outer lining, can be better carry out the nip pressure, if the softer inconvenient nip pressure that carries on of material is unfavorable for gaseous smooth circulation like this.
The edges of the first film layer 1 and the third film layer 3 are bonded by thermocompression bonding.
The body of second thin layer 2 is PET layer 8, nylon weaving layer 9, polyethylene curtain coating thin layer 11 in proper order from the outside in.
The first film layer 1 and the third film layer 3 are square, and the second film layer 2 is round.
The top opening is a square opening.
Two self-sealing strips 6 are arranged at the opening at the top of the outer lining.
The two self-sealing strips can resist certain gas pressure to prevent the self-sealing strips from being flushed by pressure in the process of clamping the outer lining.
