Technical Field

[0001] This utility model relates to the field of woven bag technology, specifically to waterproof and food-preserving plastic woven bags. Background Technology

[0002] Plastic woven bags, also known as snakeskin bags, are a type of plastic bag. The advantages of plastic woven bag packaging are that it is non-toxic and odorless, lightweight, low-cost, and reusable, making it very popular. In daily life, reusable and environmentally friendly bags are needed when shopping for groceries, and plastic woven bags are frequently used for this purpose. However, existing plastic woven bags cannot achieve both freshness preservation and waterproofing. Since it is often necessary to preserve freshness when transporting vegetables and frozen foods, current technology adds a waterproof and freshness-preserving layer to the inside of the plastic woven bag to keep the food fresh.

[0003] Existing waterproof and food-preserving plastic woven bags are widely used, such as the waterproof and food-preserving plastic woven bag disclosed in CN219566047U. However, this type of plastic woven bag is difficult to seal and has poor sealing effect. Outside air can enter the plastic woven bag, causing food to spoil quickly. In addition, when people buy vegetables, they often place the plastic woven bags on the ground, and the plastic woven bags are easily damaged by friction with the ground, causing food to fall out. Therefore, a waterproof and food-preserving plastic woven bag is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a waterproof and food-preserving plastic woven bag to solve the problems mentioned in the background art, such as the inability of existing plastic woven bags to seal properly and their susceptibility to damage.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example 1

[0026] Please see Figure 1-7 This utility model provides a technical solution:

[0027] A waterproof and food-preserving woven plastic bag includes a woven bag body 1, a waterproof and food-preserving layer 2 fixedly connected to the inner side of the woven bag body 1, and handles 3 symmetrically fixedly connected to the top outer side of the woven bag body 1. A sealing plate 4 is horizontally positioned above the handle 3 and located at the top outer side of the woven bag body 1. One sealing plate 4 has a sealing seat 5 fixedly connected to one side, and the other sealing plate 4 has a horizontally positioned sealing strip 6 fixedly connected to one side. A first pressing plate 7 is horizontally positioned on the side of the sealing plate 4 away from the sealing strip 6, and a second pressing plate 8 is horizontally positioned on the side of the sealing plate 4 away from the sealing seat 5. A pressing device 9 is symmetrically arranged on the outer sides of the first pressing plate 7 and the second pressing plate 8. The pressing device 9 includes a fixing frame 91 located on the outer sides of the first pressing plate 7 and the second pressing plate 8. A vertical groove 92 is formed at the top of the fixing frame 91, penetrating the frame. A sliding groove 92 is formed inside the groove 92. A slider 93 is dynamically connected, and a connecting plate 94 is fixedly connected to the bottom of the slider 93. A clamping bolt 95 is rotatably connected to one side of the connecting plate 94. The connecting plate 94 is located inside the fixed frame 91. The clamping bolt 95 passes through the fixed frame 91 and is threadedly connected to the fixed frame 91. A first clamping plate 7 is fixedly connected between the two connecting plates 94, and a second clamping plate 8 is fixedly connected to the rear side of the two fixed frames 91. Through the sealing plate 4, sealing seat 5, sealing strip 6, first clamping plate 7, second clamping plate 8, and clamping device 9, when using the device, the two sealing plates 4 are put together, the fixed frame 91 is placed outside the two sealing plates 4, and the clamping bolt 95 is rotated to seal and preserve the food inside the waterproof preservation layer 2. This design can seal the woven bag body 1 and prevent outside air from continuously entering the inside of the waterproof preservation layer 2, which would cause the food to deteriorate faster.

[0028] An isolation bag 10 is provided on the bottom outer side of the woven bag body 1. An adhesive layer 11 is fixedly connected to the inside of the isolation bag 10. A bottom pad 12 is fixedly connected to the bottom of the isolation bag 10. The adhesive layer 11 is bonded to the bottom outer side of the woven bag body 1. There are multiple bottom pads 12, which are evenly fixedly connected to the bottom edge of the isolation bag 10. An isolation airbag 13 is provided on the bottom inner side of the waterproof preservation layer 2. The outer side of the isolation airbag 13 is tightly attached to the inner side of the waterproof preservation layer 2. With the isolation bag 10, adhesive layer 11, bottom pad 12 and isolation airbag 13, when the user holds the handle 3 and places the woven bag body 1 on the ground, the bottom pad 12 contacts the ground first. The isolation bag 10 and bottom pad 12 can prevent the ground from directly contacting the woven bag body 1 and causing damage to the woven bag body 1. The design of the isolation airbag 13 can further protect the food inside the waterproof preservation layer 2 and prevent the food from being damaged due to hard contact with the ground.

[0029] Workflow: Before use, place the isolation bag 10 on the bottom outer side of the woven bag body 1, so that the adhesive layer 11 adheres to the bottom outer side of the woven bag body 1. Then, place the isolation airbag 13 on the bottom inner side of the waterproof preservation layer 2, so that the outer side of the isolation airbag 13 is tightly fitted to the inner side of the waterproof preservation layer 2. The woven bag body 1 can then be used normally. When using the woven bag body 1, food can be placed inside the waterproof preservation layer 2. Then, seal the woven bag body 1 by putting the two sealing plates 4 together, aligning the sealing seat 5 and the sealing strip 6 horizontally. Then, install the clamping device 9, place the fixing frame 91 on the outside of the two sealing plates 4, and rotate the clamping bolt 95. Due to the limiting effect of the sliding groove 92 and the slider 93 on the connecting plate 94, the clamping bolt 95 drives the connecting plate 94 to move inside the fixing frame 91, and the slider 93 slides inside the sliding groove 92 until the first clamping plate 7 and the connecting plate 94 are tightly fitted with one of the sealing plates 4. The inner side of the fixed frame 91 is tightly fitted with another sealing plate 4. At this time, the sealing seat 5 and the sealing strip 6 squeeze the woven bag body 1 and the waterproof preservation layer 2, thereby sealing and preserving the food inside the waterproof preservation layer 2. The design of the pressing device 9 can seal the woven bag body 1 and prevent outside air from continuously entering the inside of the waterproof preservation layer 2, which would cause the food to deteriorate faster. The design of the first pressing plate 7 and the second pressing plate 8 makes the sealing plate 4 evenly stressed, thereby improving the sealing performance of the waterproof preservation layer 2 and making the pressing device 9 more secure. When the user holds the handle 3 and places the woven bag body 1 on the ground, the bottom pad 12 contacts the ground first. The isolation bag 10 and the bottom pad 12 can prevent the ground from directly contacting the woven bag body 1 and causing damage to the woven bag body 1. The design of the isolation airbag 13 can further protect the food inside the waterproof preservation layer 2 and prevent the food from being damaged due to hard contact with the ground.
