Description

Technical Field

[0001] The utility model relates to the technical field of packaging bags, in particular to a packaging stand-up bag. Background Art

[0002] Currently, dipping sauces on the market are typically packaged in standard bags or boxes. Bags are often packaged in a four-side-sealed transparent inner bag, which is then assembled into a four-side-sealed, three-layer aluminum-coated outer bag. This requires two bags for each product, and requires secondary assembly, resulting in significant packaging and labor costs during production and processing. Furthermore, consumers must unpack both layers of packaging before consuming, significantly inconvenient. Furthermore, if the dipping sauce is not fully consumed in a single serving, the remaining dipping sauce cannot be hung or stored in a standing position using the bag. Furthermore, standard bagged packaging cannot meet the requirements for standing display and storage.

[0003] An existing patent (Announcement No. CN204846707U) discloses a self-supporting packaging bag. By providing a trapezoidal bottom and hanging holes, the bag can be hung and stand upright simultaneously, facilitating the sale of dipping sauces using the bag, making it more convenient for people to use and reducing production costs. During the implementation of this solution, the following problems were discovered in the prior art that have not been effectively addressed:

[0004] The packaging bag is directly placed in the external environment after use, which makes the sealing limited, so that the items inside are prone to mold and deterioration. In addition, the existing packaging bag is directly fixed by buckles. During the buckle fixing process, the air inside is difficult to be discharged, causing the packaging bag to bulge and easily crack due to squeezing. Utility Model Content

[0005] In order to improve the above-mentioned problem that the sealing performance of the packaging bag is limited and the buckle seal is easily bulged due to air accumulation, the utility model provides a packaging self-supporting bag.

[0006] The utility model provides a packaging stand-up bag, which adopts the following technical solutions:

[0007] A packaging self-supporting bag, comprising a self-supporting bag body, a perforation being opened on the right side of the self-supporting bag body, a first threaded block being connected to the front side of the self-supporting bag body, a connecting block being connected inside the first threaded block, a second threaded block being further connected to the lower side of the front side of the self-supporting bag body, a first receiving block being connected inside the second threaded block, and a second receiving block being further connected to the rear side of the self-supporting bag body;

[0008] The top of the self-supporting bag body is connected to a sealing layer, a snap block is provided below the sealing layer, a vent is provided on the left side of the snap block, a first bending layer is further connected to the center of the self-supporting bag body, and a second bending layer is provided on the other side of the first bending layer.

[0009] The above technical solution facilitates the bending of the stand-up bag body by arranging the first bending layer and the second bending layer on both sides of the stand-up bag body, and the sealing effect is improved by engaging the connecting block with the first receiving block. In addition, the air vent is provided to allow the gas generated during the sealing process to be discharged, thereby preventing the stand-up bag body from bursting due to excessive air inside.

[0010] Optionally, in the above-mentioned self-supporting bag packaging, the self-supporting bag body and the first bending layer are installed in an integrated manner, the width of the first bending layer is smaller than the width of the second bending layer, and the length of the first bending layer is consistent with the length of the self-supporting bag body.

[0011] With the above technical solution, the first bending layer and the second bending layer cooperate to facilitate the bending of the stand-up bag body, thereby improving the sealing effect.

[0012] Optionally, in the above-mentioned self-supporting bag packaging, the two sides of the sealing layer are respectively connected to the two sides of the self-supporting bag body, a tearing hole is provided below the sealing layer, and the length and width of the sealing layer are consistent with the length and width of the gap between the self-supporting bag bodies.

[0013] With the above technical solution, the sealing layer can be used to prevent air leakage from the vent of the stand-up bag body before use, thereby ensuring sealing during transportation.

[0014] Optionally, in the above-mentioned packaging self-supporting bag, the connection between the connecting block and the first threaded block is a threaded connection, the first threaded block is integrally installed with the self-supporting bag body, and the self-supporting bag body is integrally installed with the second threaded block.

[0015] With the above technical solution, the connecting block is easily matched with the first threaded block to make the connecting block a detachable structure, and the stand-up bag body can be removed and continued to be used after use, which is energy-saving and environmentally friendly.

[0016] Optionally, in the above-mentioned self-supporting bag packaging, the second threaded block and the first receiving block are connected by threaded connection, the first receiving block and the connecting block are in a mutually engaging structure, and the size of the first receiving block is consistent with the size of the second receiving block.

[0017] The above technical solution facilitates the cooperation between the first receiving block and the second receiving block, ensures that the stand-up bag body is always bent during use, and can be stacked during transportation for easy use.

[0018] Optionally, in the above-mentioned self-supporting bag packaging, the ventilation holes are symmetrically distributed on both sides of the clamping block, the clamping block is integrated with the self-supporting bag body, and the ventilation holes are squeezed to seal when the clamping block is clamped.

[0019] The above technical solution facilitates the cooperation between the ventilation opening and the locking block, so that the air inside the stand-up bag body can be discharged, and no air will overflow after the bag is fixed.

[0020] In summary, the present invention has at least one of the following beneficial effects:

[0021] By providing a first bending layer and a second bending layer on both sides of the self-supporting bag body, the self-supporting bag body can be bent after the buckle is closed, thereby improving its sealing performance. In addition, a vent is provided between the snapping blocks to allow the gas inside the self-supporting bag body to be discharged. However, after bending, the gas does not circulate, ensuring that the sealing effect is not affected.

[0022] By arranging a connecting block and a first storage block on both sides of the center of the self-supporting bag body, the self-supporting bag body can be quickly spliced ​​with the connecting block and the first storage block during the bending process to ensure stable bending. At the same time, the connecting block and the second storage block are spliced ​​during transportation, which is convenient for transportation and stacking. In addition, the connecting block and the storage block are detachable structures and can be removed for secondary use after use. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is combined with Figure 1-4 The utility model is described in further detail.

[0029] Please refer to the attached figure in the instruction manual Figure 1-4The utility model provides an embodiment: a packaging self-supporting bag, including a self-supporting bag main body 1, a perforation 2 is opened on the right side of the self-supporting bag main body 1, a first threaded block 6 is connected to the front side of the self-supporting bag main body 1, and a connecting block 5 is connected to the inside of the first threaded block 6. The connecting block 5 cooperates with the second threaded block 8 to make the connecting block 5 a detachable structure. The second threaded block 8 is also connected to the lower part of the front side of the self-supporting bag main body 1, and the first receiving block 7 is connected to the inside of the second threaded block 8. The connecting block 5 is fixed by the first receiving block 7 to ensure that it is automatically fixed when bent. The rear side of the self-supporting bag main body 1 is also connected to the second receiving block 9;

[0030] The top of the stand-up bag body 1 is connected to a sealing layer 3, and a snap-fit ​​block 10 is provided below the sealing layer 3. The stand-up bag body 1 is sealed by the snap-fit ​​block 10 to ensure ease of use. A vent 11 is provided on the left side of the snap-fit ​​block 10. The center of the stand-up bag body 1 is also connected to a first bending layer 4. The first bending layer 4 cooperates with the second bending layer 12 to allow the stand-up bag body 1 to be bent to improve sealing. A second bending layer 12 is provided on the other side of the first bending layer 4.

[0031] Working principle: When in use, first, tear off the sealing layer 3 above the stand-up bag body 1 to release the fixed limit of the stand-up bag body 1. After use, fit the snapping blocks 10 on the top of the stand-up bag body 1 together, squeeze the stand-up bag body 1 to squeeze out the air inside it, and then bend the stand-up bag body 1 toward the first bending layer 4, so that the connecting block 5 above the stand-up bag body 1 is close to the first receiving block 7, until the connecting block 5 and the first receiving block 7 are fixed to each other, and the sealing of the stand-up bag body 1 is completed.

[0032] As mentioned above, during transportation, the connecting block 5 is continuously connected to the second storage block 9, so that multiple self-supporting bag bodies 1 are spliced ​​with each other for convenient collective transportation. After the self-supporting bag body 1 is used, the connecting block 5, the first storage block 7 and the second storage block 9 are unscrewed in turn, and they are fixed in the kitchen position to directly fix the subsequent self-supporting bag body 1 for easy use.

[0033] It should be noted that the self-supporting bag body 1 and the first bending layer 4 are installed in an integrated manner, the width of the first bending layer 4 is smaller than the width of the second bending layer 12, and the length of the first bending layer 4 is consistent with the length of the self-supporting bag body 1. The cooperation between the first bending layer 4 and the second bending layer 12 makes it easy to bend the self-supporting bag body 1, thereby improving the sealing effect.

[0034] It should be noted that the two sides of the sealing layer 3 are respectively connected to the two sides of the self-supporting bag body 1, and a tearing hole is provided below the sealing layer 3. The length and width of the sealing layer 3 are consistent with the length and width of the gap between the self-supporting bag bodies 1. The sealing layer 3 prevents air leakage from the air vent 11 of the self-supporting bag body 1 before use, thereby ensuring sealing during transportation.

[0035] It should be noted that the connection between the connecting block 5 and the first threaded block 6 is a threaded connection. The first threaded block 6 is integrated with the self-supporting bag body 1, and the self-supporting bag body 1 is integrated with the second threaded block 8. The connecting block 5 cooperates with the first threaded block 6 to make the connecting block 5 a detachable structure. After the self-supporting bag body 1 is used, it can be removed and continued to be used, which is energy-saving and environmentally friendly.

[0036] It should be noted that the second threaded block 8 and the first receiving block 7 are connected by a threaded connection. The first receiving block 7 and the connecting block 5 are in a mutually engaging structure. The size of the first receiving block 7 is consistent with the size of the second receiving block 9. By cooperating with the first receiving block 7 and the second receiving block 9, the self-supporting bag body 1 is ensured to be always bent during use, and the self-supporting bag body 1 can be stacked during transportation for easy use.

[0037] It should be noted that the air vents 11 are symmetrically distributed on both sides of the snap block 10. The snap block 10 is installed in an integrated manner with the self-supporting bag body 1. When the snap block 10 is snapped, the air vents 11 are squeezed to make it sealed. The air vents 11 cooperate with the snap block 10 so that the air inside the self-supporting bag body 1 can be discharged, and no air will overflow after the fixation is completed.

[0038] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
