in the drawings, each reference numeral: 1. a flexible carrier; 11. stacking blocks; 111. a top layer; 112. an intermediate layer; 113. a bottom layer; 2. coating liquid; 3. and (5) packaging paper.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and detailed description, wherein it is to be understood that, on the premise of no conflict, the following embodiments or technical features may be arbitrarily combined to form new embodiments.
In the following detailed description, unless otherwise specified, words such as "top" and "bottom" having orientation indicating meanings are to be understood as orientation indicating the orientation of the drawings.
The invention provides a coating liquid bag, which is shown in figure 1 and comprises a coating liquid 1, a flexible carrier 2 and a packaging paper 3; the flexible carrier is a 2 n-layer stack 11 formed by folding a whole piece of non-woven fabric, wherein n is more than or equal to 2 and less than or equal to 4; the coating liquid is impregnated from one surface of the stacking block to the middle layer of the stacking block; the wrapping paper seals the stacked block tightly.
In the invention, the coating liquid can be a product with cleaning and processing functions such as dimethyl silicone oil, and the 'dip dyeing' is understood to be a directional penetration process of the coating liquid which can be identified by naked eyes, for example, alcohol dye is mixed in the coating liquid, and the penetration degree can be judged according to the position of the dye. The non-woven fabrics of the coating liquid bag are folded in half, and compared with a folding block formed by stacking a plurality of non-woven fabrics, the gap between the non-woven fabrics is stable and is not easy to scatter; as shown in fig. 2, the dip-dyeing of the coating liquid from one side of the stack 11 to the middle layer of the stack should be understood as being dip-dyed from the bottom layer 113 to the middle layer 112 in contact with the bottom layer, while the top layer 111 is not dip-dyed; or from the top layer to an intermediate layer in contact with the top layer, while the bottom layer is not impregnated. The coating liquid is processed into a coating liquid bag, so that the coating liquid is convenient to use, good in appearance, free of toxicity and harm, convenient to package and transport, and ideal in use performance and effect.
