Description

Technical Field

[0001] This utility model relates to the field of vacuum packaging bags, and in particular to a multi-cavity vacuum integrated packaging bag. Background Technology

[0002] The vacuum packaging bags currently in use are single-chamber structures (single-compartment bags), containing only one independent chamber. They offer the best fit for block blanks and provide good sealing. However, they cannot meet the needs of blanks of all sizes. In particular, with the increasing number of cylindrical and tile-shaped products, single-packaging can easily lead to resource waste, and packaging multiple blanks at once without proper sealing can easily cause air leakage, resulting in product oxidation.

[0003] Currently, the product structure is changing, no longer limited to square blanks. Small-sized products such as cylinders and tiles are gradually increasing. Using existing single-cavity bags to package small-sized cylindrical and tile products not only consumes a lot of materials and is inefficient, but also requires repeated packaging and sealing, resulting in high labor costs and low efficiency. If multiple pieces are forcibly mixed, it is easy to cause the bag opening to not be sealed tightly, and air leakage during vacuuming (the leakage rate is about 5% to 10%), which will cause the product to oxidize and be scrapped. Therefore, existing single-cavity bags cannot meet the efficient packaging needs of multiple-sized products, especially with poor compatibility with cylindrical blanks, resulting in both resource waste and quality risks.

[0004] To address these issues, those skilled in the art have provided a multi-cavity vacuum integrated packaging bag. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a multi-cavity vacuum integrated packaging bag, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A multi-chamber vacuum integrated packaging bag includes a main body of the packaging bag, wherein multiple sets of chamber-separating sealing strips are built into the cavity of the main body of the packaging bag, and the multiple sets of chamber-separating sealing strips divide the cavity of the main body of the packaging bag into multiple independent chambers; each of the multiple independent chambers is provided with an inner liner assembly, and the inner liner assembly includes an independent chamber body and an expansion opening sealing strip.

[0008] According to the multi-cavity vacuum integrated packaging bag, the cavity partition sealing strip is made of high-strength nylon and has a width of 5mm.

[0009] According to the multi-cavity vacuum integrated packaging bag, the main body of the packaging bag and multiple sets of chamber separation sealing strips are integrally formed, and there are no gaps between the multiple sets of chamber separation sealing strips and the main body of the packaging bag.

[0010] According to the multi-chamber vacuum integrated packaging bag, the main body of the independent chamber and the corresponding independent chamber are fixedly connected. The main body of the independent chamber is made of nylon with a thickness of 0.6mm.

[0011] According to the multi-cavity vacuum integrated packaging bag, the expansion opening sealing strip is integrally formed with the independent chamber body, and the expansion opening sealing strip is funnel-shaped.

[0012] This utility model provides a multi-cavity vacuum continuous packaging bag, which has the following beneficial effects:

[0013] (1) This application divides the main body of the packaging bag into multiple independent chambers by setting multiple sets of chamber separation sealing strips in the main body of the packaging bag. Each chamber is vacuumed independently. The chamber separation sealing strip is integrally formed with the main body of the packaging bag, which significantly improves tear resistance and avoids leakage caused by cross pressure between chambers during vacuuming. Multiple independent chambers take into account the high-efficiency packaging needs of products of various specifications, especially small-sized products such as cylinders and tiles.

[0014] (2) By fixing the main body of the independent chamber into the corresponding independent chamber, and setting an expansion opening sealing strip at the opening of the main body of the independent chamber, the filling space is expanded, which can prevent the sharp edges of the blank from scratching the partition strip. Single person can quickly complete the filling of multiple pieces, and the filling efficiency is higher. By using nylon material, both flexibility and barrier performance are taken into account.

[0024] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0025] Please see Figure 1-4 As shown, this utility model is a multi-cavity vacuum-sealed integrated packaging bag, including a packaging bag body 10. Multiple sets of chamber-separating sealing strips 11 are built into the cavities of the packaging bag body 10, dividing the cavities into multiple independent chambers. Each of the multiple independent chambers is equipped with an inner liner assembly 12, which includes an independent chamber body 13 and an expansion opening sealing strip 14. The chamber-separating sealing strips 11 are made of high-strength nylon and have a width of 5mm. The packaging bag body 10 and the multiple sets of chamber-separating sealing strips 11 are integrally formed, with no gaps between them.

[0026] Specifically, this application divides the interior of the main body 10 of the packaging bag into multiple independent chambers by setting multiple sets of chamber separation sealing strips 11 inside the chamber. Each chamber is evacuated independently. The chamber separation sealing strips 11 are integrally formed with the main body 10 of the packaging bag, which significantly improves tear resistance and avoids air leakage caused by cross pressure between chambers during evacuation. The multiple independent chambers take into account the efficient packaging needs of products of various specifications, especially small-sized products such as cylinders and tiles.

[0027] Among them, such as Figure 3-4As shown, the independent chamber body 13 is fixedly connected to the corresponding independent chamber. The independent chamber body 13 is made of nylon with a thickness of 0.6mm. The expansion opening sealing strip 14 is integrally formed with the independent chamber body 13 and is funnel-shaped. The length of the expansion opening sealing strip 14 is controlled between 50 and 70mm.

[0028] Specifically, by fixing the independent chamber body 13 into the corresponding independent chamber, and setting an expansion opening sealing strip 14 at the opening of the independent chamber body 13, the filling space is expanded, which can prevent the sharp edges of the blank from scratching the partition strip. Single person can quickly complete the filling of multiple pieces, and the filling efficiency is higher. By using nylon material, both flexibility and barrier performance are taken into account.

[0029] During use, the operator places the blank into each chamber in sequence, and the expansion opening sealing strip 14 returns to its natural position. When vacuuming, the vacuum sealing machine completes the overall evacuation in one go, and each chamber is sealed synchronously. During inspection, the inspector quickly confirms that each chamber is free of wrinkles and leaks by using the light transmission detection method.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
