Abstract
Disclosed in the present invention is a new pressure packaging device, comprising a can, wherein a sealing cup is provided at an opening at the top of the can; the sealing cup comprises an opening portion and a connecting portion; the opening portion is connected to the can; a bag is provided at the lower end of the connecting portion, and the lower end of the connecting portion is in communication with the bag; the bag is located in the can; a valve is provided in the opening portion; and an inflation hole is provided at the bottom of the can. In the new pressure packaging device of the present invention, the bag is arranged in the can, the bag is in communication with the valve by means of the sealing cup, the part of the can outside the bag is inflated with a pressurized gas, and when the valve is opened, a glass sealant in the bag can be discharged from the valve under the pressure of the gas in the can, thereby avoiding waste caused by leakage of the glass sealant.
