AI Technical Summary
Existing degradable shopping bags have low structural strength, are easily damaged, and cannot effectively separate solids and liquids, leading to spoilage of items.
A fully biodegradable shopping bag is designed, which includes a main bag body and a secondary bag body. The main bag body and the secondary bag body are connected by folding. The secondary bag body is provided with a water filter hole at the bottom and a filter cavity inside. The bottom of the main bag body is provided with a waterproof coating. The secondary bag body is fixedly connected to the inner side of the main bag body to form a holding cavity and a drawstring opening.
Improve the structural strength of shopping bags, achieve solid-liquid separation, prevent items from spoiling, and extend their service life.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of shopping bag technology, and more specifically, to a fully biodegradable shopping bag. Background Technology
[0002] "White pollution" has become a serious social problem, and how to deal with plastic waste has become a major concern for all of humanity. One of the more common approaches is to use alternative biodegradable products. Biodegradable polymer materials are made from natural polymers (such as starch, cellulose, and chitin) or agricultural byproducts through microbial fermentation or synthesis to create biodegradable polymers.
[0003] Existing biodegradable shopping bags have low structural strength and are easily damaged, affecting their normal use. Furthermore, they cannot separate the solid and liquid contents of the items inside the bags, leading to spoilage of certain items during transport.
[0004] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fully biodegradable shopping bag.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fully biodegradable shopping bag, including a main bag body, wherein a secondary bag body is provided inside the main bag body, and the top of the secondary bag body is folded outward and fixedly connected to the top periphery of the outer surface of the main bag body.
[0007] By adopting the above technical solution and setting up a main bag and a secondary bag, the overall structural strength of the shopping bag can be effectively improved. Even if one of the main bag or the secondary bag is damaged, the shopping bag can still be used normally.
[0008] The present invention is further configured such that: a filter cavity is formed between the bottom of the main bag body and the bottom of the secondary bag body, and a plurality of filter holes are evenly provided at the bottom of the secondary bag body.
[0009] The present invention is further configured such that the outer surface of the sub-bag is fixedly connected to the inner surface of the main bag.
[0010] The present invention is further configured such that: a receiving cavity is formed between the folded part of the secondary bag body and the top of the main bag body, and a pull rope is provided in the receiving cavity; the secondary bag body has two symmetrically arranged pull rope openings at the folded part.
[0011] The present invention is further configured such that a waterproof coating is provided on the bottom surface of the main bag body.
[0012] The present invention is further configured such that the waterproof coating is specifically an Ast synthetic polymer waterproof coating film.
[0013] The present invention has the following beneficial effects: 1. By setting a main bag body and a secondary bag body, the overall structural strength of the shopping bag can be effectively improved. When either the main bag body or the secondary bag body is damaged, the shopping bag can still be used normally.
[0014] 2. When items are placed inside the secondary bag, the liquid can enter the filter chamber through the water filter holes, thereby achieving solid-liquid separation and reducing the possibility of spoilage of the items inside the shopping bag. Attached Figure Description

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.
[0018] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.
[0019] As shown in the figure, a fully biodegradable shopping bag includes a main bag body 1 and a secondary bag body 2 inside the main bag body 1. The top of the secondary bag body 2 is folded outward and fixed to the top periphery of the outer surface of the main bag body 1 by heat fusion. By setting the main bag body 1 and the secondary bag body 2, the overall structural strength of the shopping bag can be effectively improved. When either the main bag body 1 or the secondary bag body 2 is damaged, the shopping bag can still be used normally.
[0020] A filter chamber 3 is formed between the bottom of the main bag body 1 and the bottom of the secondary bag body 2. Several filter holes 4 are evenly opened at the bottom of the secondary bag body 2. When items are placed in the secondary bag body 2, the liquid can enter the filter chamber 3 through the filter holes 4, thereby achieving solid-liquid separation and reducing the spoilage of items in the shopping bag.
[0021] The outer surface of the secondary bag 2 is fixedly connected to the inner surface of the main bag 1 by heat fusion to further ensure the stability of the connection between the main bag 1 and the secondary bag 2, and to improve the overall structural strength of the shopping bag.
[0022] A receiving cavity is formed between the folded part of the secondary bag body 2 and the top of the main bag body 1. A pull rope 5 is provided in the receiving cavity. The secondary bag body 2 has two symmetrically arranged pull rope openings 6 at the folded part, which can pull the pull rope 5 out from the two pull rope openings 6 for convenient use.
[0023] The bottom surface of the main bag body 1 is provided with a waterproof coating 7, which is specifically an Ast synthetic polymer waterproof coating film, which can prevent water from seeping into the bottom of the shopping bag and further improve the performance.
[0024] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
