TECHNICAL FIELD
[0001] The utility model relates to the field of vacuum compression bags, particularly to detachable hanging type partition compression bag. BACKGROUND
[0002] The hanging type compression bag can be hung after loading and compressing articles, and has a great demand in the market. At present, the hanging type compression bag is generally sealed at the bottom of the hook to the top of the bag body, and the hook and the bag body are an integral structure. The compression bag is inconvenient to store, and when storing articles, not all of them need to be hung. Therefore, the ordinary compression bag with a hook is redundant and not universal. In addition, during long-term sealed storage of the compression bag, the zipper opening may have a slow air leakage phenomenon, affecting the sealing effect. At the same time, the hanging type compression bag is not suitable for storing small and scattered articles, because the articles will sink to the bottom under the action of gravity. UTILITY MODEL CONTENTS
[0003] In view of the problems in the prior art, the detachable hanging type partition compression bag is provided, the hook and the bag body can be flexibly disassembled and combined, and the universal applicability is good. The storage and use are convenient. The second air leakage prevention structure is formed by tightly sucking the two layers of films of the bag body after the vacuum extraction of the bag body. The bag body is partitioned to prevent the articles from sinking to the bottom.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:
[0005] The detachable hanging type partition compression bag is provided with a zipper opening on one side of the bag body, the other three sides are sealed, a hook is arranged on the top edge, two layers of films on the top edge of the bag body are heat sealed and bonded, but the middle position is not connected to leave an insertion port, a heat sealed surrounding edge connected with the top edge is arranged on the left and right sides and below the insertion port, the heat sealed surrounding edge and the heat sealed top edge on the left and right sides of the insertion port form an installation cavity, and the horizontal rod of the hook is clamped in the installation cavity.
[0006] Further improvement scheme is that the heat sealed surrounding edge comprises vertical edge one and vertical edge two connected with the heat sealed top edge on the left and right sides of the insertion port respectively, and a Z-shaped step horizontal edge, heat sealed blocking edges are arranged downward on the left and right sides of the insertion port, the two heat sealed blocking edges are spaced apart from the vertical edge one and the vertical edge two on their two sides to form a clamping groove, and the horizontal rod of the hook is provided with a boss on the upper part of the two ends, and the boss can be clamped in the clamping groove. The boss on the horizontal rod of the hook cooperates with the heat sealed blocking edge on the bag body to effectively prevent the hook from sliding out, and the step structure is more convenient for installing the hook.
[0007] Still further improvement scheme is that the left side wall of the heat sealed blocking edge on the right side of the insertion port is a slope surface. The slope surface is designed to facilitate the installation of the hook.
[0008] Still further improvement scheme is that the two layers of films in the middle part of the bag body are heat sealed and bonded to form a partition separation blocking strip. The bag body is divided into multiple layers from top to bottom, and the articles are stored in the cavities to prevent the articles from sinking to the bottom.
[0009] A further improvement is to set the partition strips at horizontal intervals. This increases the airflow channels between the upper and lower areas inside the bag without affecting the extraction and discharge of air from the bag.
[0010] A further improvement is to make the end of the divider strip near the zipper opening wider than the width of the divider strip itself, forming a rounded shape to create a tear-resistant structure. When items are inserted into the zipper, the divider strip on the side near the zipper opening is easily torn by force; the larger adhesive area at the end provides some tear resistance.
[0011] A further improvement is to add a thin film strip inside the zipper opening. After items are placed inside the bag and a vacuum is applied, the negative pressure inside causes the thin film strip to adhere tightly to the two layers of film on the bag itself, forming a second airtight structure to protect the zipper opening and prevent slow air leakage during storage. Beneficial effects
[0012] This vacuum compression bag hook is detachable from the bag body, making it easy to install and remove. Without the hook, it functions as a regular compression bag; with the hook, it becomes a hanging compression bag, offering wide applicability and convenient storage. One side of the mounting cavity features a stepped structure for easy assembly and disassembly. The protrusion on the hook's crossbar engages with the heat-sealed edge on the bag body to effectively prevent the hook from slipping out. The inner film strip inside the zipper opening tightly adheres to the two layers of film on the bag body, forming a second layer of leak-proof structure to protect the zipper opening from slow leakage. Furthermore, the bag body is divided into upper and lower sections to prevent stored items from sinking to the bottom. Attached Figure Description

[0014] Figure 2 This is a schematic diagram of the structure of the hook of this utility model installed on the bag body. Detailed Implementation
[0015] like Figure 1As shown, the detachable hanging type partition compression bag, one side of the bag body 1 is provided with a zipper opening 2, the other three sides are heat sealed, the top edge is provided with a hook 3, the top edge of the bag body 1 is heat sealed and adhered by two layers of film, but the middle position is not connected to leave a socket 4, the left and right sides and the lower side of the socket (4) are provided with a heat sealed surrounding edge 5 connected with the top edge, the heat sealed surrounding edge 5 and the heat sealed top edge 6 on the left and right sides of the socket form an installation cavity 7, and the lower horizontal rod of the hook 3 is clamped in the installation cavity 7. Specifically, the heat sealed surrounding edge 5 comprises a vertical edge one 51, a vertical edge two 52 and a "Z" type step horizontal edge 53 connected with the heat sealed top edge 6 on the left and right sides of the socket respectively, and the heat sealed blocking edges 54 are arranged downward on the left and right sides of the socket respectively, the two heat sealed blocking edges 54 are spaced apart from the vertical edge one 51 and the vertical edge two 52 on the two sides to form a clamping groove 8, the upper part of the horizontal rod of the hook 3 is provided with a boss 31, and the boss 31 can be clamped in the clamping groove 8. When installing, the left end of the horizontal rod of the hook 3 is inserted into the socket first, then the left end is adjusted to extend into the left side clamping groove, the right end of the hook horizontal rod is inserted into the socket again, and the right end is adjusted to extend into the right side clamping groove, and the bosses on the two ends of the hook horizontal rod are finally clamped in the two side clamping grooves and are not easy to slip out under the blockage of the heat sealed blocking edges 54. The left side wall of the heat sealed blocking edge 54 on the right side of the socket is a slope surface 55, which is more convenient for insertion and installation.
[0016] In order to prevent the bag body from falling to the bottom, the middle part of the bag body 1 is heat sealed and adhered by two layers of film to form a partition blocking strip 9, and in this embodiment, two rows of upper and lower rows are arranged to divide the space in the bag into three layers, and the partition blocking strips 9 are arranged at equal horizontal positions, the end head 91 of the partition blocking strip close to the zipper opening is wider than the width of the partition blocking strip and is circular to form a tear-resistant structure, because when the zipper opening is opened and the articles are placed inward, the side close to the zipper opening is subjected to a large force, and the tearing is prevented.
