Abstract
Abstract There is disclosed a technique for packaging charcoal briquettes which may or may not be impregnated with a flammable liquid. The briquettes are placed in an impermeable plastic bag which is filled with an inert gas atmosphere and then collapsed closely about the briquettes. The bag is sealed and then wrapped in a paper covering impregnated with a flammable liquid. The partially completed unit is then placed and sealed in a second gas impermeable plastic bag. One or more of such unit handled masses are then placed in a conventional paper sack for delivery through ordinary channels of commerce.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
67 words
A charcoal briquette packaging comprising a sealed gas impermeable organic polymeric inner bag having therein a multiplicity of abutted charcoal briquettes, the bag being collapsed about the briquettes to provide a compact unbendable unit having a substantially reduced gas volume therein; a fiber covering, juxtaposed to the inner bag, impregnated with a flammable liquid; and a sealed gas impermeable organic polymeric outer bag surrounding the fiber covering.
Claim 2
Dependent Claim
67 words
A charcoal briquette packaging comprising a sealed gas impermeable organic polymeric inner bag having therein a multiplicity of abutted charcoal briquettes, the bag being collapsed about the briquettes to provide a compact unbendable unit having a substantially reduced gas volume therein; a fiber covering, juxtaposed to the inner bag, impregnated with a flammable liquid; and a sealed gas impermeable organic polymeric outer bag surrounding the fiber covering.
Claim 3
Dependent Claim
14 words
The package of claim 1 wherein the briquettes are impregnated with a flammable liquid.
Claim 4
Dependent Claim
21 words
The package of claim 1 wherein the inner plastic bag has been shrunk to closely conform to the charcoal briquette exteriors.
Claim 5
Dependent Claim
17 words
The package of claim 1 wherein the gaseous pressure in the inner bag is less than atmospheric.
Claim 6
Dependent Claim
14 words
The package of claim 4 wherein the inner bag contains a substantially inert atmosphere.
Claim 7
Dependent Claim
34 words
A charcoal briquette package, comprising a multiplicity of abutted charcoal briquettes; a fiber covering, enclosing the briquettes, impregnated with a flammable liquid; and a sealed gas impermeable organic polymeric bag surrounding the fiber covering.
Claim 8
Dependent Claim
34 words
A charcoal briquette package, comprising a multiplicity of abutted charcoal briquettes; a fiber covering, enclosing the briquettes, impregnated with a flammable liquid; and a sealed gas impermeable organic polymeric bag surrounding the fiber covering.
Claim 9
Dependent Claim
14 words
The package of claim 6 wherein the briquettes are impregnated with a flammable liquid.
Claim 10
Dependent Claim
34 words
The package of claim 6 further comprising another sealed gas impermeable organic polymeric bag surrounding and in intimate contact with the charcoal briquettes, the fiber covering being in intimate contact with the outer bag.
Claim 11
Independent Claim
86 words
A method of packaging charcoal briquettes, comprising placing a multiplicity of charcoal briquettes in a gas impermeable organic polymeric first bag; steps for replacing the oxygen containing atmosphere in the first bag with an inert gas atmosphere and collapsing the first bag; sealing the first bag; juxtaposing a fiber material in intimate contact with the first bag; impregnating the fiber material with a flammable liquid; and steps for sealing the fiber material, first bag and briquettes in a partially evacuated gas impermeable organic polymeric second bag.
Claim 12
Independent Claim
86 words
A method of packaging charcoal briquettes, comprising placing a multiplicity of charcoal briquettes in a gas impermeable organic polymeric first bag; steps for replacing the oxygen containing atmosphere in the first bag with an inert gas atmosphere and collapsing the first bag; sealing the first bag; juxtaposing a fiber material in intimate contact with the first bag; impregnating the fiber material with a flammable liquid; and steps for sealing the fiber material, first bag and briquettes in a partially evacuated gas impermeable organic polymeric second bag.
Claim 13
Dependent Claim
27 words
The method of claim 9 further comprising the step of impregnating the charcoal briquettes with a flammable liquid prior to placing the briquettes in the first bag.
Claim 14
Dependent Claim
18 words
The method of claim 9 wherein the juxtaposing step comprises enclosing the first bag with the fiber material.
