Description

Technical Field

[0001] This utility model relates to the field of packaging materials technology, and in particular to a PE bag that can be cleanly recycled. Background Technology

[0002] There are various types of bags used for packaging and storing objects, and PE bags are one of them. These bags are often reused during use. Because the inner surface of the bag comes into contact with the objects after each use, it will inevitably accumulate dirt to some extent. When the dirt is severe, it cannot be reused. Utility Model Content

[0003] The present invention aims to provide a PE bag that can be cleaned and reused, so that the inner surface of the bag remains clean when it is reused. This solves the problem that existing PE bags cannot be reused if the inner surface of the bag is dirty after use.

[0004] The following technical problem is solved by the following technical solution: A clean, reusable PE bag, comprising a bag body with an open top forming a bag opening, the bag body being made of PE, characterized in that the bag body includes a plurality of sub-bags nested together in sequence, the opening of the outermost sub-bag having an inwardly turned-up flange, the inwardly turned-up flange forming a limiting groove with the side wall of the outermost sub-bag, the upper ends of all the sub-bags in the outermost sub-bag being inserted into the limiting groove, and the open ends of all the sub-bags being connected together by a plurality of detachable connecting structures. For reuse, the innermost sub-bag is first removed and discarded, and then reused, thus ensuring that the inner surface of the bag is clean during reuse.

[0005] Preferably, the bag also includes two handles. Two loop holes are provided on each of the front and rear side walls of the bag body. These loop holes pass through all the individual bag sections. The detachable connection structure includes a connector and a locking head threaded to one end of the connector. There are four detachable connection structures, with the connectors of each structure correspondingly inserted into the four loop holes. The two ends of one handle are fixed to the connectors of two detachable connection structures located on one side wall of the bag body, and the two ends of another handle are fixed to the connectors of two detachable connection structures located on the other side wall of the bag body. This provides a specific technical solution for the detachable connection structure. In this technology, the detachable connection structure is integrated with the handles, forming a connection structure between the handles and the bag body, serving a dual purpose. When a bag section needs to be discarded, the locking head is unscrewed, the bag section is removed, and then the locking head is screwed back on.

[0006] Preferably, the clip head includes a snap-fit ​​section and a connecting section. The connecting section passes through the lanyard hole and has an internal threaded hole. The connector has an external threaded section, which is threaded into the internal threaded hole to achieve a threaded connection between the connector and the clip head. This minimizes the portion of the clip head protruding from the bag surface.

[0007] Preferably, the connector is cylindrical, the connecting segment is cylindrical, the diameter of the connector is equal to the diameter of the connecting segment, the internal threaded hole and the connecting segment are coaxial, and the threaded segment and the connector are coaxial. This ensures good flatness of the connection between the connector and the connecting segment, thereby providing smooth passage when threading the rope through the hole.

[0008] Preferably, the card head is located inside the bag body.

[0009] Preferably, the end face of the connector connected to the handle rope has a connecting hole. The end of the handle rope passes through the connecting hole. When the connector is squeezed, the connecting hole shrinks and clamps tightly onto the end of the handle rope, thus fixing the connector and the handle rope together. This makes fixing the handle rope and connector convenient.

[0010] Preferably, the end of the handle rope has a large-diameter section. This improves the reliability of the connection between the handle rope and the connector.

[0011] Preferably, the bottom walls of two adjacent layers of bags are fixed together by several tear blocks distributed in the left-right direction. When separating the inner and outer layers of bags, the bags are torn apart at the tear blocks. This not only keeps the adjacent bags together during use to prevent them from moving when the items inside are taken out, thus avoiding interference with the taking and putting away of the items, but also makes it easy to separate the inner and outer layers of bags.

[0012] Preferably, the tear block includes an upper protrusion integrally formed with the inner layer of the bag and a lower protrusion integrally formed with the outer layer of the bag, the upper and lower protrusions being bonded together with adhesive. The inner and outer layers of the bag are torn apart at the junction of the upper and lower protrusions.

[0013] Preferably, the tear blocks between all adjacent bag sections are aligned one-to-one, with the cross-sectional area of ​​the upper protrusion gradually decreasing from top to bottom, and the cross-sectional area of ​​the lower protrusion gradually increasing from top to bottom. An annular tear guide groove extending circumferentially along the tear block is formed between the upper and lower protrusions. This reliably ensures that when the bag section is removed, the tear occurs at the connection point of the upper and lower protrusions. This invention has the following advantages: it keeps the inner surface of the bag clean during secondary use. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] See Figures 1 to 4 A clean, reusable PE bag includes a bag body 1 and two handles 2. The top of the bag body is open to form a bag opening. The bag body is made of PE. The bag body includes several sub-bags 3 (four in this embodiment, i.e., four layers) nested together. The opening of the outermost sub-bag 4 has an inward-turned edge 5, which forms a limiting groove 6 with the side wall of the outermost sub-bag. The upper ends of all the sub-bags in the outermost sub-bag are inserted into the limiting groove, and the open ends of all the sub-bags are connected together by several detachable connecting structures 7. For reuse, the innermost sub-bag is first removed and discarded, and then reused, thus ensuring that the inner surface of the bag is clean during reuse.

[0020] The bag body has two drawstring holes 8 on each of its front and rear side walls, through which all the sub-bag sections pass. The detachable connection structure includes a connector 9 and a locking head 10 threaded to one end of the connector. There are four detachable connection structures, with the connectors of each structure correspondingly inserted into the four drawstring holes. The two ends of one handle rope are fixed to the connectors of two detachable connection structures located on one side wall of the bag body, and the two ends of another handle rope are fixed to the connectors of two detachable connection structures located on the other side wall of the bag body. The locking head includes a locking section 11 and a connecting section 12. The connecting section passes through the drawstring hole and has an internal threaded hole 13. The connector has an external threaded section 14, which is threaded into the internal threaded hole to achieve a threaded connection between the connector and the locking head. The connector is cylindrical, and the connecting section is cylindrical. The diameter of the connector is equal to the diameter of the connecting section. The internal threaded hole and the connecting section are coaxial, and the threaded section and the connector are coaxial. The locking head is located inside the bag body. A connecting hole 15 is provided on the end face of the connector that connects to the handle rope. The end of the handle rope passes through the connecting hole. The connector is squeezed, causing the connecting hole to shrink and tighten around the end of the handle rope, thus fixing the connector to the handle rope. The end of the handle rope has a large diameter section 16. The bottom walls of two adjacent compartments are fixed together by several tear blocks 17 distributed in the left-right direction. When separating the inner and outer compartments, the compartments are torn apart at the tear blocks. This not only fixes the adjacent compartments together during use, preventing movement when taking out the contents, thus avoiding interference with taking out and putting in the contents, but also facilitates the separation of the inner and outer compartments. The tear block includes an upper protrusion 18 integrally formed with the inner compartment and a lower protrusion 19 integrally formed with the outer compartment. The upper and lower protrusions are bonded together with adhesive. The tear blocks between all adjacent bag bodies are aligned one-to-one. The cross-sectional area of ​​the upper protrusion gradually decreases from top to bottom, and the cross-sectional area of ​​the lower protrusion gradually increases from top to bottom. An annular tear guide groove 20 extending circumferentially along the tear block is formed between the upper and lower protrusions.
