[0001] This utility model relates to the field of shopping bag technology, and in particular to an expandable, environmentally friendly, portable shopping bag. Background Technology

[0002] Shopping bags are bags used to carry items while shopping. The main types of shopping bags available on the market are plastic shopping bags, non-woven shopping bags, paper shopping bags, and cotton and linen shopping bags.

[0003] Traditional shopping bags have a fixed capacity, making it impossible to flexibly adjust their size to meet actual carrying needs. Furthermore, most traditional shopping bags lack environmental friendliness, easily leading to resource waste and environmental pollution. Therefore, there is an urgent need in the market for a shopping bag that is both environmentally friendly and can adjust its capacity according to the usage scenario. Utility Model Content

[0004] The main purpose of this utility model is to provide an expandable, environmentally friendly, and portable shopping bag. It aims to provide a shopping bag that can meet the needs of daily commuting in terms of lightness, and can also cope with sudden large-capacity loading, thus combining practicality and environmental protection.

[0005] To achieve the above objectives, this utility model proposes an expandable, environmentally friendly, portable shopping bag, comprising a base, and a first bag body and a second bag body connected to adjacent sides of the base.

[0006] The first bag body includes a first wide side, a second wide side, a first long side, and a second long side;

[0007] The second bag body includes a third wide side, a fourth wide side, a third long side, and a fourth long side;

[0008] The base is connected to an adjustment part with the same area as the base on both sides away from the first bag and the second bag. An extension part with the same area as the base is connected to the side of two adjacent adjustment parts away from the base. The two adjustment parts are provided with a zigzag part relative to the base.

[0009] The two adjustment parts are bent into the base under the action of the folded part, and the extension part is positioned above the base;

[0010] The side of the first long side adjacent to the first wide side is connected to the base, and the length of the first long side is equal to the outer perimeter of the base;

[0011] The third long side is connected to the base on the side adjacent to the third wide side, and the length of the third long side is equal to the outer perimeter of the base.

[0012] The first wide side connects to the third wide side, and the second wide side connects to the fourth wide side;

[0013] The first bag body is folded along the central axis so that the first wide side connects to the second wide side, and the second bag body is folded along the central axis so that the third wide side connects to the fourth wide side. The first bag body and the second bag body together wrap around the base.

[0014] In one embodiment of this application, the first wide side and the third wide side are integrally formed, or a first connecting member is provided between the first wide side and the third wide side.

[0015] In one embodiment of this application, the second wide side and the fourth wide side are integrally formed, or a second connecting member is provided between the second wide side and the fourth wide side.

[0016] In one embodiment of this application, the first long side is provided with a third connector relative to the base.

[0017] In one embodiment of this application, the third long side is provided with a fourth connector relative to the base.

[0018] In one embodiment of this application, the adjusting portion and the extending portion are provided with mating portions relative to the third connecting member and the fourth connecting member.

[0019] In one embodiment of this application, a handle is provided on the first bag body, and / or on the second bag body, and / or between the first bag body and the second bag body.

[0020] By adopting the above technical solution, this utility model has the following advantages:

[0021] The shopping bag of this application structurally includes a base portion and a first bag body and a second bag body connected to two adjacent sides of the base and used to construct the side walls of the shopping bag. The first bag body structurally includes a first wide side, a second wide side, a first long side, and a second long side. The second bag body structurally includes a third wide side, a fourth wide side, a third long side, and a fourth long side. The base itself includes an adjustment portion connected to the adjacent two sides of the base away from the first bag body and the second bag body, and an extension portion located at the end of the adjustment portion away from the base. The two adjustment portions share a zigzag line that runs through the two adjustment portions. The first bag body, the second bag body, the base, the adjustment portion, and the extension portion are all rectangular. The above structure is relatively simple, and the above structure makes the shopping bag easy to carry and allows the user to change the structural state of the shopping bag according to their own needs, thereby achieving rapid and stable changes in the capacity of the shopping bag and effectively improving the user experience.

[0022] The excess portions of the first and third long sides can be connected to the base through external structures or connecting structures on them to form a complete and structurally stable shopping bag. The second and fourth long sides form the openings of the shopping bag, which can ensure the convenience of using the shopping bag.

[0023] Specifically, the base, two adjustment sections, and extension section can be unfolded into a plane, forming the base of a large-capacity shopping bag within that plane. The perimeter of the adjustment section and the folded section is equal to that of the base, making the perimeter of the base twice that of the base. Since the lengths of the first and third long sides of the first and second bag bodies are both equal to the perimeter of the base, the first and second bag bodies can perfectly wrap around the base, achieving the effect of quickly forming a large-capacity shopping bag. Through the cooperation of the above structures, the portable shopping bag of this application can effectively cope with sudden large-capacity loading needs and effectively take into account practicality.

[0024] The typical structure of a portable shopping bag is as follows: two adjustable sections bend towards the base. The base, the two adjustable sections, and the folded section are generally square. The base and the extension are symmetrical about the folded section. When the adjustable sections bend towards the base, and the adjustable sections themselves bend inwards along the central folded section towards the base, the two adjustable sections connect to each other and are housed within the base. Simultaneously, the extension is positioned above the base during this process. Since the first wide side connects to the third wide side, and the second wide side connects to the fourth wide side, the first and second bag bodies can form a single unit. Folding the two bag bodies along their axes connects the four wide sides. Together, the lengths of the first and third long sides are halved, allowing the first and second bag bodies to wrap around the base and extension. This structure reduces the shopping bag's capacity by approximately four times compared to a large-capacity shopping bag, easily meeting daily commuting needs and making the bag easy to carry. This structure enables the shopping bag to handle scenarios requiring large capacity, reducing the number of shopping bags users need to carry. Furthermore, the shopping bag is reusable multiple times. This structure balances practicality and environmental friendliness, effectively improving the user experience. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0033] The following is in conjunction with the appendix Figs. 1 to 3 The present invention will be further described below.

[0034] To achieve the above objectives, this utility model proposes an expandable, environmentally friendly, portable shopping bag, comprising a base 1, and a first bag body 4 and a second bag body 5 connected to adjacent sides of the base 1.

[0035] The first bag body 4 includes a first wide side 41, a second wide side 42, a first long side 43, and a second long side 44;

[0036] The second bag body 5 includes a third wide side 51, a fourth wide side 52, a third long side 53, and a fourth long side 54;

[0037] The base 1 is connected to an adjustment part 2 with the same area as the base 1 on both sides away from the first bag body 4 and the second bag body 5. An extension part 3 with the same area as the base 1 is connected to the side of the two adjacent adjustment parts 2 away from the base 1. The two adjustment parts 2 are provided with a folded part 21 relative to the base 1.

[0038] The two adjustment parts 2 are bent into the base 1 under the action of the folded part 21, and the extension part 3 is positioned above the base 1;

[0039] The side of the first long side 43 adjacent to the first wide side 41 is connected to the base 1, and the length of the first long side 43 is equal to the outer perimeter length of the base 1.

[0040] The third long side 53 is connected to the base 1 on the side adjacent to the third wide side 51, and the length of the third long side 53 is equal to the outer perimeter length of the base 1.

[0041] The first wide side 41 is connected to the third wide side 51, and the second wide side 42 is connected to the fourth wide side 52;

[0042] The first bag body 4 is folded along the central axis so that the first wide side 41 is connected to the second wide side 42. The second bag body 5 is folded along the central axis so that the third wide side 51 is connected to the fourth wide side 52. The first bag body 4 and the second bag body 5 together wrap around the base 1.

[0043] The shopping bag of this application structurally includes a base 1 and a first bag body 4 and a second bag body 5 connected to two adjacent sides of the base 1 and used to construct the side walls of the shopping bag. The first bag body 4 structurally includes a first wide side 41, a second wide side 42, a first long side 43, and a second long side 44. The second bag body 5 structurally includes a third wide side 51, a fourth wide side 52, a third long side 53, and a fourth long side 54. The base 1 itself includes an adjustment part 2 connected to the adjacent two sides of the base 1 away from the first bag body 4 and the second bag body 5, and an extension part 3 located at the end of the adjustment part 2 away from the base 1. The two adjustment parts 2 share a folded line 21 that runs through the two adjustment parts 2. The first bag body 4, the second bag body 5, the base 1, the adjustment part 2, and the extension part 3 are all rectangular. The above structure is relatively simple, and the above structure makes the shopping bag easy to carry and allows the user to change the structural state of the shopping bag according to their own needs, thereby realizing a rapid and stable change in the capacity of the shopping bag and effectively improving the user experience.

[0044] The excess portions of the first long side 43 and the third long side 53 can be connected to the base 1 through an external structure or a connecting structure provided thereon, so as to form a complete and structurally stable shopping bag. The second long side 44 and the fourth long side 54 form an opening for the shopping bag, which can ensure the convenience of using the shopping bag.

[0045] Specifically, the base 1, the two adjustment parts 2, and the extension part 3 can be unfolded into a plane and form the base of a large-capacity shopping bag in this plane. The perimeter of the adjustment part 2 and the folded part 21 is equal to that of the base 1, so that the perimeter of the base is twice that of the base 1. Since the lengths of the first long side 43 and the third long side 53 of the first bag body 4 and the second bag body 5 are both equal to the perimeter of the base 1, the first bag body 4 and the second bag body 5 can wrap around the base to achieve the effect of quickly forming a large-capacity shopping bag. Through the cooperation of the above structures, the portable shopping bag of this application can effectively cope with the sudden large-capacity loading needs and effectively take into account practicality.

[0046] The typical structure of a portable shopping bag is as follows: two adjustment sections 2 bend towards the base 1. The base 1, the two adjustment sections 2, and the folded section 21 are generally square. The base 1 and the extension section 3 are symmetrical about the folded section 21. When the adjustment section 2 bends towards the base 1, and the adjustment section 2 itself bends inward along the central folded section 21 towards the base 1, the two adjustment sections 2 can connect to each other and be stored inside the base 1. At the same time, the extension section 3 will be above the base 1 during this process. Since the first wide side 41 is connected to the third wide side 51, and the second wide side 42 is connected to the fourth wide side 52, the first bag body 4 and the second bag body 5 can form a whole. The two bag bodies are respectively aligned along the axis. The folding mechanism connects the four wide sides, effectively halving the lengths of the first long side 43 and the third long side 53. This allows the first bag body 4 and the second bag body 5 to wrap around the base 1 and the extension 3. This structure reduces the shopping bag's capacity by approximately four times compared to a large-capacity shopping bag, easily meeting daily commuting needs and making the bag easy to carry. This structure enables the shopping bag to handle scenarios requiring large capacity, reducing the number of shopping bags users need to carry. Furthermore, the shopping bag is reusable multiple times. This structure balances practicality and environmental friendliness, effectively improving the user experience.

[0047] The first wide side 41 and the third wide side 51 are integrally formed, or a first connecting member is provided between the first wide side 41 and the third wide side 51.

[0048] The first bag body 4 and the second bag body 5 can be integrated. Specifically, the first wide side 41 and the third wide side 51 share the same side, without the need for additional connecting structures.

[0049] Alternatively, the first bag body 4 and the second bag body 5 are two completely independent parts, with the first wide side 41 and the third wide side 51 being separate from each other. A first connector is provided between the first wide side 41 and the third wide side 51. The first connector itself can be adhesive tape, a Velcro structure, or a connecting strip with connecting holes or connecting buckles connected to the first wide side 41 or the third wide side 51. The Velcro structure can also be pre-sewn onto the first wide side 41 or the third wide side 51, with the other side being a mating connection structure. Through this structure, the first wide side 41 and the third wide side 51 can be detachably connected, and both can be quickly and stably adjusted, ensuring the rapid deformation of the portable shopping bag and improving the user experience.

[0050] The second wide side 42 and the fourth wide side 52 are integrally formed, or a second connecting member is provided between the second wide side 42 and the fourth wide side 52.

[0051] The first bag body 4 and the second bag body 5 can be integrated. Specifically, the second wide side 42 and the fourth wide side 52 share the same side, without the need for additional connecting structures.

[0052] Alternatively, a second connector may be provided between the two, and the structure of the second connector is similar to that of the first connector.

[0053] Meanwhile, when the shopping bag is in its normal state, a fifth connector with a structure similar to the first connector is provided between the axis of the first bag body 4 and the axis of the second bag body 5, which can ensure the structural stability of the shopping bag in its normal state.

[0054] The first long side 43 is provided with a third connector relative to the base 1.

[0055] The third long side 53 is provided with a fourth connector relative to the base 1.

[0056] The third and fourth connectors are structurally similar to the first connector and can be used to shape the shopping bag itself.

[0057] The adjustment part 2 and the extension part 3 are provided with mating parts relative to the third connector and the fourth connector.

[0058] When the above connectors are Velcro or connecting strips with connecting holes or buckles, the adjustment part 2 and the extension part 3 need to be provided with corresponding mating parts for connecting with Velcro / connecting strips to ensure the structural stability of the shopping bag in the expanded state.

[0059] A handle is provided on the first bag body 4, and / or on the second bag body 5, and / or between the first bag body 4 and the second bag body 5.

[0060] Handles make shopping bags easy to use and carry.
