Abstract

Abstract An apparatus for the storage of cut tobacco is disclosed. The apparatus comprises a mobile structure which supports a bag having openings at the top and bottom for loading and unloading. At least the bottom opening of the bag is closeable. The bag is made of a material inert to tobacco which is both flexible and moisture retaining and having surface frictional characteristics such that a bridging effect is created within the stored tobacco within the opposing inner surfaces of the bag along its length thereby reducing pressure on the tobacco near the bottom of the bag.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 108 words
An apparatus for the storage of cut tobacco comprising a bag hung from a mobile supporting structure, the bag material comprising a mesh overlaid with a plastic finish, said bag having openings at the top and bottom for loading and unloading, at least the bottom opening being closeable, said bag being made of a material inert to tobacco, flexible and moisture retaining, said material having surface frictional characteristics and said bag having cross sectional dimensions such that a bridging effect is created within the stored tobacco between opposing inner surfaces of the bag along its length thereby reducing pressure in the tobacco near the bottom of the bag.
Claim 2
Independent Claim 108 words
An apparatus for the storage of cut tobacco comprising a bag hung from a mobile supporting structure, the bag material comprising a mesh overlaid with a plastic finish, said bag having openings at the top and bottom for loading and unloading, at least the bottom opening being closeable, said bag being made of a material inert to tobacco, flexible and moisture retaining, said material having surface frictional characteristics and said bag having cross sectional dimensions such that a bridging effect is created within the stored tobacco between opposing inner surfaces of the bag along its length thereby reducing pressure in the tobacco near the bottom of the bag.
