Description

Technical Field

[0001] The utility model relates to the technical field of shopping bags, in particular to a shopping bag. Background Art

[0002] Currently, shopping bags in our lives mainly include plastic, paper, cotton and linen, etc. Among them, paper shopping bags have limited weighing capacity due to their own low structural strength; although cotton and linen shopping bags have higher structural strength than paper shopping bags, their poor water resistance limits their scope of use; plastic shopping bags are the most widely used in life, but with the implementation of the plastic ban, biodegradable shopping bags have gradually come into people's view.

[0003] Biodegradable shopping bags can be divided into food contact and non-food contact types. They are mainly made of resin as the main raw material, have a carrying structure, and are used to hold and carry goods in sales, service and other places. Currently, shopping bags generally have double handles, but the handles are often stretched or broken due to excessive force during use. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a shopping bag, including a bag body and a handle part, the bag body and the handle part are formed in an integrated manner by blow molding, the two sides are folded inwards into folded edges, and then formed by cutting.

[0005] Preferably, the bag body portion comprises a bag body, an opening is arranged at the upper portion of the bag body, and a bottom seal is arranged at the bottom of the bag body.

[0006] Preferably, the bottom seal is configured as a flat bottom structure.

[0007] Preferably, the handle portion includes a first handle and a second handle, and the second handle is located in the middle of the bag opening.

[0008] Preferably, two first handles are provided, and the two first handles are located at two sides of the bag opening.

[0009] Preferably, the first handle and the second handle are both provided with handle sealing lines.

[0010] Preferably, the length of the second handle is the same as that of the first handle.

[0011] Preferably, the length of the second handle is the same as the length of the bag body.

[0012] Preferably, the shopping bag has a width of 30-35 mm and a thickness of 0.03-0.04 mm.

[0013] Technical effects and advantages of the utility model:

[0014] In the utility model, a multi-handle biodegradable shopping bag is manufactured by changing the cutting method, and each handle is subjected to a smaller pulling force, thereby preventing the shopping bag handles from being stretched or even broken due to excessive force during use.

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0019] See also Figures 1-2 As shown, in this embodiment, a shopping bag is provided, including a bag body part and a handle part. The bag body part and the handle part are formed in an integrated manner by blow molding, and the two sides are folded inwardly into folded edges and then formed by cutting.

[0020] Specifically, the bag body portion includes a bag body 1, an opening is arranged at the upper portion of the bag body 1, a bottom seal 5 is arranged at the bottom of the bag body 1, and the bottom seal 5 is arranged to be a flat bottom structure, so that the volume utilization efficiency of the bag body 1 is maximized when containing objects.

[0021] Specifically, the handle part includes a first handle 2 and a second handle 3. Two first handles 2 are provided, and the two first handles 2 are located at both sides of the opening of the bag body 1. The second handle 3 is located in the middle of the opening of the bag body 1. The first handle 2 and the second handle 3 are both provided with a handle sealing line 4, and the length of the second handle 3 is the same as that of the first handle 2.

[0022] Furthermore, cutting lines 6 are arranged on the bag body, and four cutting lines 6 are arranged.

[0023] In another embodiment, the length of the second handle 3 is the same as that of the bag body 1. When placing a smaller object, the object is placed into the bag body 1 through the opening between the first handle 2 and the second handle 3. When placing a larger object, the second handle 3 is placed in the bag body 1. The larger object is placed into the bag body 1 through the opening between the two first handles 2, and the second handle 3 supports the bottom of the object, so the bottom of the bag body 1 is not easily damaged.

[0024] In this embodiment, the cutting is performed in W shape to form a W-shaped multi-handle shopping bag. The W-shaped multi-handle shopping bag has a width of 30-35 mm, a thickness of 0.03-0.04 mm, and a folding width of 5-7.5 mm.

[0025] In the control group, U-shaped cutting was adopted to cut the U-shaped double-handle shopping bag. The width of the U-shaped double-handle shopping bag was 30-35mm, the thickness was 0.03-0.04mm, and the folding width was 5-7.5mm.

[0026] The W-shaped shopping bag in the implementation group and the U-shaped shopping bag in the control group in this embodiment are compared, see Table 1:

[0027]

[0028] When the width and thickness of the W-shaped and U-shaped bags are the same, after putting 5kg of items in and lifting them 1000 times, there is no obvious change in the handles of the control group and the experimental group; when putting 10kg of items in and lifting them 1000 times, the handles of the control group show obvious stretching, while the handles of the experimental group show slight stretching; when putting 15kg of items in and lifting them 1000 times, the handles of the control group break, while the handles of the experimental group do not break but show obvious stretching.

[0029] Under the condition of the same load-bearing capacity, in a shopping bag with multiple handles, each handle is subjected to a smaller pulling force, thereby preventing the shopping bag handles from being stretched or even broken due to excessive force during use.

[0030] In another embodiment, the shopping bag is made of biodegradable materials, such as starch and cellulose, which can be decomposed by microorganisms and eventually form water, carbon dioxide and organic matter.

[0031] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
