Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly bags, and in particular to GRS recycled environmentally friendly bags. Background Technology

[0002] GRS eco-friendly bags are storage bags that have obtained Global Recycling Standard (GRS) certification. GRS is an international voluntary product standard that specifies third-party certification requirements for recycled materials, chain of custody, social and environmental practices, and chemical restrictions. GRS bags are typically made from recycled materials such as RPE, RPP, and RPET, making them an environmentally friendly alternative across various industries.

[0003] In order to improve the service life of eco-friendly bags, existing technologies usually improve the bag structure. For example, existing technologies disclose an eco-friendly bag including an eco-friendly bag body. A set of symmetrical buttons are fixedly installed on the inner surfaces of both sides of the eco-friendly bag body. The outer surface of the buttons is fitted with a buckle strap. The lower surface of the two buckle straps is fixedly connected with a stretch strap. An integrated mesh fabric for cushioning is fixedly connected between the stretch straps. A set of symmetrical sliding adjustment grooves are opened on the upper surfaces of both sides of the eco-friendly bag body. An adjustable length handle strap is slidably fastened in the sliding adjustment groove. The upper surface of the handle strap on the same side is fixedly connected with a handle. A set of symmetrical grooves are opened inward on the inner surfaces of both sides of the eco-friendly bag body below the buttons. A first Velcro is fixedly installed in the groove. A second Velcro is embedded in the surface of the stretch strap near the buckle strap. The first Velcro and the second Velcro are glued and fixed, which improves the practicality.

[0004] While the mesh structure proposed in the aforementioned disclosed technology can provide inspiration for the structural improvement of GRS recycled eco-friendly bags, it still has certain shortcomings in practical application. It only uses buttons, straps, and a pair of Velcro to install the mesh, resulting in a high stress concentration when the pressure is transferred from the mesh to the bag body, which can easily lead to premature damage to the bag body. Furthermore, the mesh only serves as a buffer and support, with limited functionality. If it is to be applied to GRS recycled eco-friendly bags, it is necessary to further improve its structure. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing the GRS recycled eco-friendly bag.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a GRS recycled eco-friendly bag, comprising an outer bag body and two sets of handles. The outer bag body consists of a front bag surface, a rear bag surface, a left bag surface, a right bag surface, and a bottom surface. Each of the front bag surface, rear bag surface, left bag surface, right bag surface, and bottom surface is composed of an inner layer, a support layer, and an outer layer arranged sequentially from the inside out. The two sets of handles are located at the upper end of the outer bag body and are respectively located on the upper side of the front bag surface and the rear bag surface. Both sets of handles are C-shaped with the opening facing downwards, and reinforcing structures are provided between the two ends of the C-shape and the outer bag body. The upper edge is provided with a sealing edge to enhance the connection strength between the handle and the outer bag body. The front and rear bag surfaces of the outer bag body are provided with interlayers on opposite sides. The left, right and lower sides of the interlayers are fixedly connected to the inner wall of the outer bag body. The upper end of the interlayers is not connected to the inner wall of the outer bag body. A partition cavity is formed between the front bag surface and the corresponding interlayer, and between the rear bag surface and the corresponding interlayer. An inner bag body is provided inside the outer bag body. Connecting pieces are provided on the front and rear sides of the upper edge of the inner bag body. The two sets of connecting pieces are detachably connected to the two partition cavities by a Velcro structure.

[0007] As a further description of the above technical solution:

[0008] The Velcro structure includes two sets of first rough surfaces, first hook surfaces, second rough surfaces, third rough surfaces, and second hook surfaces. The two sets of first rough surfaces are respectively located on opposite sides of the front and rear pocket surfaces. The two sets of first hook surfaces are respectively located on opposite sides of the two interlayers, and the positions of the two sets of first hook surfaces are respectively opposite to the position of one set of first rough surfaces. The two sets of second rough surfaces are respectively located on opposite sides of the two interlayers. The two sets of second hook surfaces are respectively located on the front and rear side walls of the inner bag body. The two sets of third rough surfaces are respectively located on the outer walls of the two sets of connecting pieces. When the connecting pieces are folded towards the outer wall of the inner bag body, the positions of the third rough surfaces and the second hook surfaces correspond. When the outer bag body and the inner bag body are combined, the connecting pieces extend into the partition cavity, and the third rough surface is connected to the first hook surface, and the second rough surface is connected to the second hook surface.

[0009] As a further description of the above technical solution:

[0010] The reinforcing structure includes two sets of connecting ribs, which are respectively fixedly connected to the inner wall of the front bag and the inner wall of the rear bag, and are both at the same horizontal height as the sealing edge. The length of the connecting ribs is the same as the length of the outer bag body in the left and right direction.

[0011] As a further description of the above technical solution:

[0012] The handle consists of a frame and a surface layer wrapped around the outer wall of the frame, and the upper wall of the connecting rib is fixedly connected to the frame.

[0013] As a further description of the above technical solution:

[0014] The support layer has a honeycomb structure.

[0015] As a further description of the above technical solution:

[0016] Both sets of inner bag bodies have handle holes on their front and rear side walls and the inner wall of the connecting piece. After the two sets of connecting pieces are folded towards the front and rear sides of the inner bag body, the handle holes on the connecting pieces correspond to the handle holes on the inner bag body.

[0017] As a further description of the above technical solution:

[0018] Both sets of handles have a buffer sleeve fitted on their outer walls.

[0019] This utility model has the following beneficial effects:

[0020] 1. Compared with existing technologies, the GRS recycled eco-friendly bag has an inner bag body that can be used independently or as a buffer layer for the outer bag body through the combination of connecting piece and Velcro structure. The alignment design of the handle hole after the connecting piece is folded ensures the convenience of carrying when the inner bag body is used alone.

[0021] 2. Compared with existing technologies, the GRS recycled eco-friendly bag has a three-sided interlayer fixed to the inner wall of the outer bag to form a partition cavity. The load of the inner bag is transferred to the entire perimeter of the outer bag through multi-point connection of Velcro. The honeycomb support layer inside the outer bag can further improve the support strength and increase the service life.

[0022] 3. Compared with existing technologies, the GRS recycled eco-friendly bag has a handle connected to the outer bag body through connecting ribs. When carrying it, the force is dispersed through the connecting ribs, which enhances the resistance to deformation and improves the connection strength between the handle and the outer bag body.

Detailed Implementation

[0031] 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.

[0032] Reference Figures 1 to 6 The GRS recycled eco-friendly bag provided by this utility model includes an outer bag body 1 and two sets of handles 2;

[0033] In order to achieve lightweight and structural reinforcement of the eco-friendly bag, the outer bag body 1 is composed of a front bag surface, a back bag surface, a left bag surface, a right bag surface and a bottom surface. The front bag surface, the back bag surface, the left bag surface, the right bag surface and the bottom surface are all composed of an inner layer 102, a support layer 103 and an outer layer 101 arranged from the inside to the outside. The support layer 103 has a honeycomb structure.

[0034] The honeycomb support layer 103 reduces its own weight while achieving multi-directional force transmission through the hexagonal unit structure, effectively solving the problem of bag collapse caused by insufficient rigidity of recycled materials;

[0035] To improve carrying comfort and durability, both sets of handles 2 are set on the upper part of the outer bag body 1 and are located on the upper side of the front bag surface and the rear bag surface respectively. Both sets of handles 2 are fitted with cushioning sleeves 4 on their outer walls.

[0036] The cushioning sleeve 4 is made of high-density foam, which can relieve hand pressure under load.

[0037] To address the tearing issue at the handle connection, both handles 2 are C-shaped with the opening facing downwards. Reinforcing structures are provided between the two ends of the C-shape and the outer bag body 1. The outer bag body 1 has a sealing edge 3 along its upper edge to enhance the connection strength between the handle 2 and the outer bag body 1 in conjunction with the reinforcing structure. The reinforcing structure includes two sets of connecting ribs 14, which are fixedly connected to the inner wall of the front bag surface and the inner wall of the rear bag surface, respectively, and are at the same horizontal height as the sealing edge 3. The length of the connecting ribs 14 is the same as the length of the outer bag body 1 in the left and right directions. The handle 2 consists of a frame 202 and a surface layer 201 wrapped around the outer wall of the frame 202. The upper wall of the connecting ribs 14 is fixedly connected to the frame 202.

[0038] When the handle 2 bears a load, the connecting rib 14 evenly distributes the force along the transverse direction of the bag body. Combined with the double-layer sewing structure of the sealing edge 3, the stress concentration factor is greatly reduced.

[0039] To achieve modular functional expansion, the front and rear pocket surfaces of the outer bag body 1 are each provided with a layer 6 on opposite sides. The left and right sides and the bottom of the layer 6 are fixedly connected to the inner wall of the outer bag body 1. The upper end of the layer 6 is not connected to the inner wall of the outer bag body 1. A partition cavity is formed between the front pocket surface and the corresponding layer 6, and between the rear pocket surface and the corresponding layer 6. An inner bag body 5 is provided inside the outer bag body 1. Connecting pieces 10 are provided on both the front and rear sides of the upper edge of the inner bag body 5. The two sets of connecting pieces 10 are detachably connected to the two partition cavities by a Velcro structure. The Velcro structure includes two sets of first rough surfaces 7, first hook surfaces 8, second rough surfaces 9, third rough surfaces 12, and second hook surfaces 13. The rough surfaces 7 are respectively set on the opposite side of the front bag surface and the back bag surface. The two sets of first hook surfaces 8 are respectively set on the opposite side of the two sets of interlayers 6 and the two sets of first hook surfaces 8 are respectively opposite to the position of the first rough surface 7. The two sets of second rough surfaces 9 are respectively set on the opposite side of the two sets of interlayers 6. The two sets of second hook surfaces 13 are respectively set on the front and rear side walls of the inner bag body 5. The two sets of third rough surfaces 12 are respectively set on the outer wall of the two sets of connecting pieces 10. When the connecting piece 10 is folded towards the outer wall of the inner bag body 5, the third rough surface 12 and the second hook surface 13 are in the same position. When the outer bag body 1 and the inner bag body 5 are combined, the connecting piece 10 extends into the partition cavity, and the third rough surface 12 is connected to the first hook surface 8 and the second rough surface 9 is connected to the second hook surface 13.

[0040] The inner bag 5 can be quickly assembled and disassembled using the Velcro structure, and in the assembled state, it can form a stable force transmission channel through the three-layer connection interface (first hook surface 8 / third rough surface 12, second rough surface 9 / second hook surface 13).

[0041] To ensure continuity of use when switching functions, handle holes 11 are provided on the front and rear side walls of the two sets of inner bag bodies 5 and the inner wall of the connecting piece 10. After the two sets of connecting pieces 10 are folded towards the front and rear sides of the inner bag body 5, the handle holes 11 on the connecting piece 10 correspond to the handle holes 11 on the inner bag body 5.

[0042] When the inner bag 5 is used independently, the folded connecting piece 10 makes the handle hole 11 form a double-layer reinforced structure to prevent the edge of the hole from tearing when carrying.

[0043] Working principle: The honeycomb support layer 103 reduces its own weight while achieving multi-directional force transmission through the hexagonal unit structure, effectively solving the problem of bag collapse caused by insufficient rigidity of recycled materials; the cushioning sleeve 4 is made of high-density foam material, which can relieve hand pressure under load; when the handle 2 bears a load, the connecting rib 14 evenly distributes the force along the transverse direction of the bag, and with the double-layer sewing structure of the sealing edge 3, the stress concentration coefficient is greatly reduced; the inner bag 5 can be quickly assembled and disassembled by the Velcro structure, and can also form a stable force transmission channel in the combined state through the three-layer connecting interface (first hook surface 8 / third rough surface 12, second rough surface 9 / second hook surface 13); when the inner bag 5 is used independently, the folded connecting piece 10 makes the handle hole 11 form a double-layer reinforced structure to avoid tearing of the hole edge when carrying.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
