Description

Technical Field

[0001] The utility model belongs to the technical field of packaging bags, in particular to an aluminum foil sealed packaging bag. Background Art

[0002] Aluminum foil bags, also known as pure aluminum bags, generally refer to aluminum-plastic composite vacuum packaging bags, which are often used to package food, medicine, daily necessities, etc. Due to its own characteristics, it is used more and more widely in our daily life. It has good oxygen barrier and waterproof properties, and the water and oxygen permeability is 1. It is non-toxic and tasteless, meeting the packaging standards of food and medicine.

[0003] However, the aluminum foil bag also has certain disadvantages when used. The aluminum foil is very brittle and difficult to laminate, so the aluminum foil bag is easily damaged and leaks, which in turn affects its oxygen-barrier and waterproof properties. After the aluminum foil bag is slightly damaged and leaks, it is difficult for people to detect. Therefore, an aluminum foil sealed packaging bag is proposed. Utility Model Content

[0004] The utility model aims to provide an aluminum foil sealed packaging bag, which can not only use a sealing sheet and a positioning ring to seal the bag after part of the air in the bag is discharged, but also expand if the bag leaks, which is convenient for people to observe. At the same time, when the bag contains many items and it is inconvenient to observe the expansion, whether there is leakage can be observed by observing the position of the detection sheet, thereby improving the flexibility of use. The bag can also be opened by an elastic support sheet, thereby facilitating the placement of items in the bag, thereby solving the existing technical problems.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] An aluminum foil sealed packaging bag comprises: a bag body, a self-sealing strip for sealing the bag body is fixed between the inner walls on both sides of the top of the bag body, and a gas leakage detection mechanism is provided on one side of the bag body;

[0007] The air leakage detection mechanism includes a vent cylinder and a positioning ring. The vent cylinder is fixedly connected to one side of the bag body. The circumferential inner wall of the vent cylinder is fixedly connected to a fixing frame. A sliding rod penetrating therefrom is slidably connected to one side of the fixing frame. A positioning sheet is fixedly connected to one end of the sliding rod. The positioning ring is fixedly connected to the circumferential inner wall of the vent cylinder. The other end of the sliding rod is fixedly connected to a supporting frame. A sealing sheet used in conjunction with the positioning ring is fixedly connected to one side of the supporting frame. By installing the detection mechanism on one side of the bag body, the sealing sheet and the positioning ring can be used to seal the bag body after part of the air in the bag body is discharged. If the bag body leaks, the bag body will expand, which is convenient for people to observe.

[0008] An observation component is arranged on one side of the support frame to observe air leakage.

[0009] As a further solution of the utility model, the observation component includes a connecting rod, which is fixedly connected to the other side of the support frame, and the other end of the connecting rod is fixedly connected to a detection piece, which is slidably connected in the ventilation cylinder, and one side of the detection piece is provided with a plurality of penetrating air holes. By installing the detection piece in the ventilation cylinder, the detection piece is connected to the support frame. When the bag contains many items and it is inconvenient to observe the expansion, the top cover is opened, and then the position of the detection piece can be observed to observe whether there is a leakage, thereby improving the flexibility of use.

[0010] As a further solution of the utility model, a plurality of rubber rods are fixedly connected to the circumferential inner wall of the ventilation cylinder, and the rubber rods are bent and abut against the detection sheet.

[0011] As a further solution of the utility model, one end of the ventilator is threadedly connected to a top cover, and an anti-slip strip is provided on the circumference of the top cover.

[0012] As a further solution of the utility model, a V-shaped elastic support piece is bonded between the inner walls of both sides of the bag body. By setting the elastic support piece in the bag body, the bag body can be opened by the elastic support piece, thereby facilitating the placement of items in the bag body.

[0013] As a further solution of the utility model, both sides of the top of the bag body are provided with extension pieces for opening the bag body, and one side of the bag body is provided with a penetrating hanging hole.

[0014] The present application uses a self-sealing strip to seal the bag body. When opening, the self-sealing strip on the top of the bag body is torn open through the extension pieces on both sides of the top of the bag body, and then the items that need to be kept are put into the bag body, and the bag body is supported by the elastic support piece to facilitate the insertion of the items. After the insertion is completed, the bag body is sealed again through the self-sealing strip, and the top cover is removed to squeeze the remaining space of the bag body. The air in the bag body pushes the sealing piece, so that the sealing piece and the positioning ring are out of contact, and then the gas in the bag body is discharged, and then the bag body forms a negative pressure space under the support of the elastic support piece, and the sealing piece and the positioning ring are in contact to seal the bag body. Finally, the top cover is reset and the top cover is in contact with the detection piece. The detection piece pushes the sealing piece against one side of the positioning ring through the connecting rod and the support frame to increase the sealing effect. If the bag body leaks, the expansion degree of the bag body can be observed. If the bag body is not obviously observed, the top cover is removed. If the bag body leaks, the negative pressure state disappears, and the detection piece extends out of the vent tube under the push of the rubber rod, and is then observed by people.

[0015] The embodiments of the present invention have the following beneficial effects:

[0016] In the utility model, by installing a detection mechanism on one side of the bag body, the bag body can be sealed by using a sealing sheet and a positioning ring after part of the air in the bag body is discharged. If the bag body leaks, the bag body will expand, which is convenient for people to observe.

[0017] In the utility model, by installing a detection piece in the ventilator, the detection piece is connected to the support frame. When the bag contains many items and it is inconvenient to observe the expansion, the top cover can be opened to observe whether there is leakage by observing the position of the detection piece, thereby improving the flexibility of use.

[0018] In the utility model, by arranging the elastic support sheet in the bag body, the bag body can be opened by the elastic support sheet, thereby facilitating the placement of articles in the bag body.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
