Thus, the part of the folded part 528, which exceeds the end of the bag body 521, can be plastically sealed with the bag body 510, so that the two parts are fixed, and the bag is convenient to manufacture.

The method of using the packaging bag of the present embodiment is the same as the method of using the packaging bag of the fourth embodiment.

Referring to fig. 17 and 18, a packaging bag according to a sixth embodiment of the present invention is different from the packaging bag of the fifth embodiment in that: the liquid storage bags are different.

Specifically, the liquid storage bag 620 of the present embodiment includes a bag body 621, the bag body 621 includes a folded portion 628, and the second end 626 of the liquid storage bag 620 has a second notch 622 for exposing the folded portion 628. The first end 624 of the receptacle 620 extends outward to form a protrusion 623, and the protrusion 623 and the second notch 622 are identical in shape and size. Therefore, when the liquid storage bags are manufactured, the second notch of the previous liquid storage bag is matched with the convex part of the next liquid storage bag, the manufacturing is convenient, and materials can be saved.

In this embodiment, the second end 626 may be fixed to the bag 510 by plastic-sealing the folded portion 528 to the bag 510 or by adhering the folded portion to the bag 510 by an adhesive, and the first end 624 may be fixed to the bag 510 by plastic-sealing the protrusion 623 to the bag 510. Because the projection of the convex portion 623 on the surface of the bag body 621 is overlapped with the projection of the second notch 622 on the surface of the bag body 621, the material can be greatly saved, the cost is reduced, and the profit is improved.

The packaging bag is simple in structure and convenient to use. When the packaging bag is used, pulling force in opposite directions is applied to the main body and the tearing portion of the bag body by two hands until the tearing portion is separated from the main body, the first end of the liquid storage bag is driven by the tearing portion to be far away from the second end until the weak portion of the liquid storage bag is broken, so that liquid in the liquid storage bag flows into the inner cavity, a product to be soaked is wetted, and the wetted product is taken out for use. According to the technical scheme, the packaging bag body and the liquid storage bag can be opened simultaneously in one step, so that the product taking time is reduced, the waiting time of a patient is shortened, and the pain of the patient is relieved; the liquid storage bag does not need to be broken by a large external force, so that the use complexity is reduced, and the use is convenient; the liquid storage bag can be broken at the same time when the bag body is torn, so that the surface of the product can be directly soaked, and the situation that a user directly takes out the product which is not soaked without reading a specification can be avoided. Thus, the package of the present invention is advantageous in use as a whole.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
