A spray can product capable of preventing leakage where used or stored in a tilted or an inverted position, and keeping good safety and liquid retention even where a flammable liquefied gas is used. The spray can product is formed by filling a spray can having an ejection opening with a liquefied gas and an absorbing body for retaining liquid, and the absorbing body is composed of an assembly of cellulose fibers containing at least 45 mass % of fine cellulose fibers having a fiber length of 0.35 mm or less. The absorbing body compressed into a block-shaped configuration corresponding to that of the spray can is accommodated within the spray can while defining a space on the side of an ejection opening, and a lid-like member is provided between the space and the absorbing body to protect a surface of the absorbing body in a gas permeable manner.

1. A spray can product manufactured by filling a liquefied gas and an absorbing body for retaining liquid in a spray can having an ejection opening, comprising: the absorbing body being composed of an assembly of cellulose fibers containing at least 90 mass % of cellulose fibers having a fiber length of 1.5 mm or less, the absorbing body being compressed into a block-shaped configuration corresponding to that of the spray can and being accommodated within the spray can, while defining a space between the election opening and the absorbing body, anda disk-shaped member being provided between the space and the absorbing body protecting a surface of the absorbing body in a gas permeable manner, the disk-shaped member including a disk-shaped porous body adapted to be press-fitted in the spray can into close contact with the surface of the absorbing body. 2. The spray can product as claimed in claim 1, wherein the disk-shaped porous body is composed of one of a non-woven fabric and a foam resin. 3. The spray can product as claimed in claim 1, wherein the absorbing body is prepared by previously forming said assembly of cellulose fibers into a columnar block-shaped compressed body with a configuration corresponding to that of the spray can, and directly filling said columnar block-shaped compressed body in the spray can. 4. The spray can product as claimed in claim 1, wherein the liquefied gas is a flammable liquefied gas. 5. The spray can product as claimed in claim 1, wherein the liquefied gas is composed of a gas exhibiting an ozone-depleting potential of 0, and containing no hydrofluorocarbon. 6. The spray can product as claimed in claim 1, wherein the absorbing body is composed of an assembly of cellulose fibers containing at least 45 mass % of fine cellulose fibers having a fiber length of 0.35 mm or less.
