Description

Technical Field

[0001] The present application relates to the field of packaging bags, and in particular to a stand-up packaging bag. Background Art

[0002] The official name of the stand-up packaging bag (self-supporting bag), "Doypack", originated from the French Thimonier Company. In 1963, Mr. M. Louis Doyen, then CEO of the French Thimonier Company, successfully applied for a patent for the Doypack self-supporting bag. Since then, doypack has become the official name of the self-supporting bag and has been used to this day. By the 1990s, the self-supporting bag was recognized in the US market and then popularized worldwide. With the progress of society and the improvement of people's aesthetic level, the design and printing of self-supporting bags have become more and more colorful, and their forms of expression have become more and more diverse.

[0003] For example, patent No. 202223484995.2 discloses a vertical packaging bag, which includes a bag body, a front of the bag body, a back of the bag body, and a side of the bag body. The front of the bag body and the back of the bag body are respectively provided with a carrying hole in the middle of the upper part, and a hole is provided in the upper part of the side of the bag body, and a carrying rope is connected to the hole. A base is provided at the bottom of the bag body, and a support plate is installed on the upper surface of the base. Two support rods 2 are respectively installed on both sides of the front of the bag body, and a support rod 1 is installed in the middle of the front of the bag body. However, the following deficiencies still exist in actual use:

[0004] The vertical packaging bag of the above patent is difficult to keep the side wall of the bag in a vertical state manually again after being folded and stored many times. In addition, when in use, the bag has a carrying rope fixedly connected to the top of the bag. When lifting heavy objects, the weight of the objects gathers at the bottom of the bag. The user's hands lift the bag at the top, which can easily cause the carrying rope to fall off the side wall of the bag, causing damage to the objects inside the bag. After being folded many times, the appearance of the bag will also be greatly affected. Utility Model Content

The extension block 1 203 and the slide groove 1 204 are provided to prevent small debris from falling into the hollow column 1 210, and at the same time, the contact between the parts inside the hollow column 1 210 and the outside world can be reduced to prevent the wear and corrosion of the internal parts. The bottom of the block 1 201 is fixedly connected to the fixed block 1 205 by welding, the bottom surface of the block 202 is fixedly connected to the fixed block 206 by welding, and the fixed block 1 205 and the fixed block 206 are elastically connected.

[0046] By setting, the user manually slides the card block 1 201 and the card block 2 202 in the long groove 102, so that the card block 1 201 and the card block 2 202 are close to each other, and through the card block 1 201 and the card block 2 202 approaching each other, the extension block 1 203 fixedly connected to one side of the bottom of the card block 1 201 slides inside the slide groove 1 204 in the direction of the card block 202. At this time, the fixed block 1 205 and the fixed block 2 206 fixedly connected to the bottom surfaces of the card block 1 201 and the card block 2 202 also begin to approach each other, and the spring 207 that fixes the fixed block 1 205 and the fixed block 206 together begins to contract through the fixed block 1 205 and the fixed block 2 206 approaching each other. The circular column 208 on one side of the circular column 206 begins to guide the fixed column 209 to slide toward the inside of the circular ring of the circular column 208, and the extension block 213 fixedly connected to the fixed block 1 205 and the fixed block 206 on one side, through the mutual approach of the fixed block 1 205 and the fixed block 206, the extension block 213 begins to slide toward the middle of the hollow column 1 210 in the slide groove 212.
