Vacuum packaging product

Abstract

The disclosure provides a vacuum packaging product. The vacuum packaging product includes an outer packaging member and a cartridge configured for use in an electronic cigarette. The cartridge is filled with an aerosol-forming substrate. The cartridge is packed and hermetically sealed in the outer packaging member in a vacuum state. Since the outer packaging member is in a vacuum state, a pressure difference exists between the inside and the outside of the outer packaging member due to the vacuum state of the outer packaging member, and the outer packaging member is contracted, so as to better seal the cartridge that has been filled with the aerosol-forming substrate, and to avoid leakage caused by possible high temperature, high pressure or negative pressure during transportation.

What is claimed is: 
     
         1 . A vacuum packaging product, comprising an outer packaging member and a cartridge configured for use in an electronic cigarette, wherein the cartridge is filled with an aerosol-forming substrate, the cartridge is packed and hermetically sealed in the outer packaging member in a vacuum state. 
     
     
         2 . The vacuum packaging product according to  claim 1 , wherein an inner wall of the outer packaging member is provided with a reactive coating layer capable of reacting physically or chemically with the aerosol-forming substrate. 
     
     
         3 . The vacuum packaging product according to  claim 2 , wherein the reactive coating layer is a color-changing coating layer. 
     
     
         4 . The vacuum packaging product according to  claim 3 , wherein the reactive coating layer is coated on the inner wall of the outer packaging member in a manner of dipping, depositing, spraying, or pasting. 
     
     
         5 . The vacuum packaging product according to  claim 3 , wherein a pattern or a character is provided on the reactive coating layer. 
     
     
         6 . The vacuum packaging product according to  claim 1 , wherein the outer packaging member is made of a transparent or translucent material. 
     
     
         7 . The vacuum packaging product according to  claim 1 , wherein the outer packaging member comprises a receiving portion, the receiving portion is in a vacuum state, and the cartridge is packed and hermetically sealed in the receiving portion. 
     
     
         8 . The vacuum packaging product according to  claim 7 , wherein the outer packaging member further comprises a hanging portion connected with the receiving portion, the hanging portion and the receiving portion are integrally formed to form the outer packaging member, the vacuum packaging product is capable of being hung in a fixed position through the hanging portion. 
     
     
         9 . The vacuum packaging product according to  claim 8 , wherein a junction is provided between the hanging portion and the receiving portion, the junction is provided with at least one tearing opening, the junction is capable of being destroyed along the tearing opening to open the receiving portion and then take out the cartridge. 
     
     
         10 . The vacuum packaging product according to  claim 9 , wherein the junction is provided with a sealing strip, the sealing strip seals an opening of the receiving portion, and after the junction is destroyed along the tearing opening, the sealing of the sealing strip on the opening of the receiving portion is removed.
