Technical Field

The invention belongs to the technical field of daily portable articles, and relates to a reusable environment-friendly bag, in particular to a light, simple and environment-friendly portable bag and a manufacturing method thereof.

Background

In the existing market, the environment-friendly portable bag mainly takes an environment-friendly shopping bag as a main part and is used for replacing a plastic bag when shopping and goods are purchased in a supermarket so as to reduce the use of disposable plastic bags and achieve the purpose of assisting in environment protection. But environmental protection shopping bag structural style in the existing market is single, and the bag body is inside to lack the function and distinguish, often is that a pocket holds all article, and the consumer is when using, and article can't be categorised accomodate, and it is inconvenient to take article, and the small part article of easily appearing can not find, and big article can not be put down, and liquid and solid are mixed and are put mutual pollution scheduling problem, have seriously reduced consumer's use and have experienced the sense. This problem makes the use of eco-friendly shopping bags in the existing market still less frequent. Therefore, the existing environment-friendly shopping bags cannot be really matched with the environment-friendly concept, and the initiative of consumers in using the products is mobilized.

In order to attract the purchase of consumers, a part of environment-friendly shopping bags in the market are added with a large amount of pattern innovation and color innovation during production, and the intention is to attract and stimulate the purchase desire of the consumers through vision. The environment-friendly shopping bag with the structure can not only waste a large amount of printing ink, but also pollute the environment by the generated chemical dye, and is substantially against the environment-friendly concept. In addition, the current market mainly adopts a production mode of flat cutting of cloth, the cloth needs to be cut for multiple times when the environment-friendly shopping bag is produced, the production process is complex, the production period is long, and the whole production process consumes high labor cost and time cost; on the other hand, leftover materials generated in the cloth cutting process can not be effectively utilized, and waste of cloth is caused.

Disclosure of Invention

In order to solve the defects in the prior art, the invention aims to provide a light, simple and environment-friendly portable bag and a manufacturing method thereof, which are used for carrying out design optimization and innovation on the external image and the internal function of the portable bag so as to solve the defects of single style, single function and single use scene of the same type of products in the existing market, improve the problem of low utilization rate of the existing products and finally achieve the purpose of improving the acceptance of consumers on the portable bag.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows: a portable bag with light weight, simple structure and environmental protection comprises a bag body and shoulder straps which are fixedly connected into a whole, wherein the bag body is formed by sewing a whole cloth after being folded; the bag body comprises a front pocket and a rear pocket which are arranged in parallel on the side surfaces, and the upper half parts of the opposite side surfaces of the front pocket and the rear pocket are sewn together to form a middle pocket of the bag body.

As the limitation of the invention, the shoulder strap is sewed on the outer side surface of the front pocket along the length direction of the bag opening of the front pocket and is fixedly arranged below the bag opening of the front pocket.

As another limitation of the invention, the bag body is made of Tyvek cloth, and the surface of the cloth is provided with a PU coating.

As a further limitation of the invention, the outer surface of the bag body is provided with a two-dimensional code for attracting consumers to the on-line platform.

As still further another limitation of the present invention, the front pocket and the rear pocket are coupled at their lower ends, the inner spaces of the front pocket and the rear pocket are communicated through the lower portions, and a gap is left between the lower portions of the opposite sides of the front pocket and the rear pocket.

The invention also discloses a manufacturing method of the light, simple and environment-friendly portable bag, which comprises the following steps in sequence:

s1, sewing a pair of paired edges of the rectangular cloth together;

s2, folding the sewn cloth in half, wherein the folding lines are perpendicular to the sewing lines in the step S1, and forming a front pocket and a rear pocket of the bag body;

s3, after the cloth is folded in half, sewing the upper half parts of the two opposite side surfaces of the cloth into a pocket shape to form a middle pocket of the bag body;

s4, sewing the shoulder strap on the bag body to obtain the light, simple and environment-friendly portable bag as claimed in any one of claims 1-6.

In step S1, the rectangular cloth is divided into four equal parts, and two parts are folded inwards; the rectangular piece of material is then folded to a collinear pair of edges and sewn together.

In another limitation of the present invention, in step S4, the shoulder strap is sewn to the outer side surface of the front pocket along the longitudinal direction of the bag opening of the front pocket.

As a further limitation of the present invention, after the step S3 is completed, the extension cloth is sewn along the side line of the rear pocket flap to form an extension of the rear pocket flap.
