Description

Technical Field

[0001] The utility model relates to the technical field of packaging paper bags, in particular to a packaging paper bag with a reinforcement structure at the bottom. Background Art

[0002] Paper bags refer to any bag that contains a portion of paper. There are many varieties of paper bags, various paper materials, and many styles, which can be displayed in many forms.

[0003] Traditional paper bags usually consist of a paper bag body and a hand rope, with a simple structure, but have the following shortcomings in actual use:

[0004] 1. When packaging heavier objects, the bottom of the paper bag is prone to cracking and the structural strength is low.

[0005] 2. The length of the hand rope is fixed and cannot be adjusted according to usage, which has limitations in use.

[0006] Therefore, we propose a packaging paper bag with a reinforced structure at the bottom. Utility Model Content

A packaging paper bag with a reinforced bottom structure is proposed.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A packaging paper bag with a reinforced structure at the bottom, comprising:

[0010] The bag body has cardboard bonded to the bottom, plastic blocks bonded to the four corners of the cardboard, plastic plates bonded to the middle sections of both sides of the cardboard, two symmetrically arranged channels are provided inside the plastic plates, a U-shaped plate is integrally formed on the surface of the plastic plates, the U-shaped plate is bonded and fixed to the bag body, and a plurality of hooks are integrally formed on one side of the U-shaped plate;

[0011] A plurality of limit blocks, the plurality of limit blocks are evenly distributed on the outer walls of both sides of the bag body, the limit blocks are all bonded and fixed to the bag body, and at least two limit blocks are provided on the same side;

[0012] Two hand ropes, which pass through the limit blocks and channels on the same side respectively, are used to lift the paper bags.

[0013] In a possible design, reinforcing ribs are provided between the hook and the U-shaped plate.

[0014] In a possible design, inner walls of the hooks are provided with protrusions.

[0015] In a possible design, a plurality of elastic grooves are provided on one side of the U-shaped plate, and the elastic grooves and the hooks are arranged alternately.

[0016] In a possible design, a groove is formed on one side of the plastic plate.

[0017] In a possible design, a carrying block is fixedly provided at the top end of the carrying rope.

[0018] In this application, when using, just hold the handle block to lift the paper bag;

[0019] When adjusting the length of the hand rope, put your fingers into the groove and pull the hand rope, then connect the hand rope and the hook. The more hooks are used, the shorter the effective pulling length of the hand rope is, which makes the paper bag farther from the ground, avoiding contact between the paper bag and the ground.

[0020] Beneficial effects:

[0021] In the utility model, the packaging paper bag with a reinforced structure at the bottom can strengthen the bottom structural strength of the packaging paper bag by setting multiple structures such as cardboard, plastic blocks and plastic plates, so as to avoid cracking at the bottom of the paper bag;

[0022] In the utility model, the packaging paper bag with a reinforced structure at the bottom can adjust the length of the hand rope according to the usage through the provision of the hand rope and the hook, so that the bottom of the paper bag is as far away from the ground as possible to avoid the contact between the paper bag and the ground. It is suitable for people of different heights and is simple and convenient to adjust.

[0023] In the utility model, the bottom structural strength of the packaging paper bag can be strengthened to avoid cracking at the bottom of the paper bag. The length of the hand rope can be adjusted according to the usage to avoid the contact between the paper bag and the ground. The adjustment is simple and convenient, and is suitable for people of different heights. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Example 1

[0031] Reference Figure 1-Figure 4 , a packaging paper bag with a reinforced structure at the bottom, comprising:

[0032] The bag body 1 is the main part of the packaging paper bag, which is made of paper material and has good load-bearing capacity and foldability. A cardboard 2 is bonded to the bottom of the bag body 1. The cardboard 2 is made of hard material, such as cardboard or plastic board, and its purpose is to strengthen the load-bearing capacity of the bottom of the bag body 1 to prevent the bottom from being damaged due to loading heavy objects. Plastic blocks 3 are bonded to the four corners of the cardboard 2, and plastic plates 4 are bonded to the middle sections of both sides of the cardboard 2. The plastic blocks 3 cooperate with the plastic plates 4 to prop up the cardboard 2 to avoid direct friction between the cardboard 2 and the ground, and to avoid the cardboard 2 from reducing the structural strength due to wear. Two symmetrically arranged channels 8 are provided inside the plastic plates 4 for passing the hand rope 6 to facilitate users to lift the packaging paper bag. A U-shaped plate 10 is integrally formed on the surface of the plastic plates 4. The U-shaped plate 10 is bonded and fixed to the bag body 1, and a plurality of hooks 11 are integrally formed on one side of the U-shaped plate 10 for adjusting the actual use length of the hand rope 6.

[0033] A plurality of limit blocks 5, the plurality of limit blocks 5 are evenly distributed on the outer walls of both sides of the bag body 1, the limit blocks 5 are all bonded and fixed to the bag body 1, and at least two limit blocks 5 are provided on the same side for limiting the hand rope 6;

[0034] Two hand ropes 6 are respectively passed through the limit block 5 and the channel 8 on the same side.
