From this, adopt the utility model discloses the liquid medicine in the sealed bag is convenient for pour to the bottleneck of specific position of embodiment, and still can preserve certain time after taking out partial medicine, conveniently stores, transports and takes.
In addition, according to the embodiment of the utility model, the cross section of the bottle mouth is circular, and the diameter of the circle is 3-8 cm; and the outer edge of the bottle mouth protrudes 2.5-6.5 cm higher than the front surface of the bag body. Therefore, by adopting the specific bottle nozzle provided by the embodiment of the utility model, a user can pour out liquid from the flexible packaging sealing bag conveniently without side flow, splashing and the like, and the diameter of the circular bottle nozzle can be adjusted properly according to the viscosity of the liquid.
Additionally, according to the utility model discloses an outside is further provided with the external screw thread, and the internal thread that the bottle lid inboard further set up and the external screw thread phase-match of bottleneck. From this, adopt the utility model discloses bottle neck and bottle lid that the screw thread matches after the user pours liquid from this soft-packing sealed bag, still can seal remaining liquid in the preservation sealed bag, conveniently continue to store, transport and take.
In addition, according to the utility model discloses an embodiment, this edge sealing's width is 0.3 ~ 1.2 cm. The inventor unexpectedly finds that if the width of the edge seal is less than 0.3cm, the risk of bag breaking and leakage exists in the lifting or transporting process after the edge seal is filled with liquid auxiliary materials, medicines or foods, so that the width of the edge seal is at least 0.3 cm; on the contrary, if the width of the edge seal exceeds 1.2cm, the liquid capacity of the flexible packaging bag is too small, which increases the transportation cost and causes waste of resources. From this, adopt the utility model discloses the edge sealing of specific width, the transportation of being convenient for can hinder the gas, hinder wet to guarantee pharmaceutic adjuvant liquid, medicine, or food storage and the stability of transportation in.
Additionally, according to the utility model discloses an embodiment, the top edge of this handle ring further sets up 1 ~ 3cm apart from the top edge of the bag body. The inventor unexpectedly finds that if the distance between the upper edge of the handle ring and the upper edge of the bag body is less than 1cm, the distance is less than the width of the edge seal, so that the sealing property and the strength of the sealing bag are reduced, and the storage and the transportation of the flexible packaging sealing bag are influenced; if the distance between the upper edge of the handle ring and the upper edge of the bag body is more than 3cm, the distance may exceed the common length of human palms, and is not beneficial to the movement of the flexible packaging sealing bag. From this, adopt the utility model discloses the handle ring of specific position, the removal and the transportation of the flexible packaging sealing bag of being convenient for.
