[0002] The volume of the 55-gallon iron drum is equivalent to 200L. Traditionally, 55-gallon iron drums are used to fill chemical liquid products. After the product is used up, it must be cleaned before recycling or re-use. 1. The cleaning mechanism can be found, but there are environmental protection 2. High cleaning costs undoubtedly increase product costs, which is not conducive to products participating in market competition; 3. Chemical product cleaning wastewater flows out to pollute water sources, which is not conducive to low-carbon environmental protection

[0022] The first embodiment: as Figure 1 to Figure 2 as shown,

[0023] A 200L liquid packaging structure, including a turnover box and a liquid packaging bag 1 with a volume of 200L placed in the turnover box. The liquid bag is composed of double-layer or multi-layer PE film, and the bag body 3 is a square bag. The bag cover 2 is also a square structure, and the number of tie bars 6 is four, which are fixed on the center line of each side of the bag body 3, and the sides of the adjacent tie bars 6 are connected successively, and the tie bars 6 can tighten the bag body to prevent the bag body from The body is bulging and deformed. The bag cover 2 is made up of two films, large and small, the large film is outside, and the small film is inside. The large film exceeds the small film by 8cm, and the excess flash is pasted on the liner with a strong adhesive tape to fix it. The large film is a PET and PE composite material film, the small film is a PE film, the PET face of the ...

[0027] The second embodiment: as image 3 and Figure 4 shown;

[0028] A liquid packaging structure, the bag body 3 is a round bag, the bag body 3 is a double-layer PE tube film, the bottom of the bag body 3 is sealed horizontally, and the two ends form sharp corners, and the two sharp corners are bent and inserted into the bottom plate of the turnover box 7, tape the corners to the bottom plate 7. in, image 3 The line at A in the middle means that when sealing the bottom of the tube film, according to the direction of the arrow at A, the tube film will be flattened and sealed horizontally (such as Figure 4 ). Both the outer film and the inner film of the bag cover 2 are made of PE, the outer film of the bag cover 2 is a square film, the inner film is a circular film, and the outer film and the inner film are welded together on the bag body 3, The flash formed by the square film is fixed on the liner with strong tape.

[0029] In an embodiment, the turnover box is a p...

Abstract

The invention discloses a liquid packing structure. The liquid packing structure comprises a transfer box and a liquid packing bag put in the transfer box; the liquid packing bag includes a bag cover, a bag body, a bag bottom and a valve port; the bag cover is thermally sealed on the bag body; the valve port is formed in the bag cover; the bag cover consists of inner and outer two layers of films; the edge of the outer layer of film extends to the outer side so as to form a flange on the outer side of the bag body; and the flange is fixed with a lining plate positioned in the transfer box. The liquid packing structure is used for replacing a traditional filling iron barrel; and the liquid packing bag is easy to be recovered and free of being cleaned, so that the cost can be largely reduced.

Description

technical field [0001] The invention relates to the technical field of chemical liquid packaging, in particular to a liquid packaging structure. Background technique [0002] The volume of the 55-gallon iron drum is equivalent to 200L. Traditionally, 55-gallon iron drums are used to fill chemical liquid products. After the product is used up, it must be cleaned before recycling or re-use. 1. The cleaning mechanism can be found, but there are environmental protection 2. The high cost of cleaning undoubtedly increases the cost of products, which is not conducive to products participating in market competition; 3. The outflow of chemical product cleaning wastewater pollutes water sources, which is not conducive to low-carbon environmental protection. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a liquid packaging structure that can avoid cleaning, has low cost, and can replace filling iron drums. [0004] The te...
