US4526790A — Chewing gum product

Claim 1

Independent Claim 109 words

An article of manufacture comprising a deformable container having a capped extrusion orifice, said container being filled with a chewing gum composition, said composition being resistant to syneresis over protracted storage periods and being extrudable under ambient temperature conditions, said composition including gum base, sweetener, about 11% or more water by weight, and an activated, thermally reversible solution of a gelling agent, said gel solution being solid at ambient temperatures said gum composition having been introduced into said container at a temperature above the reversal temperature of said gel composition by an extrusion process thereby to introduce laminar flow in said composition in the course of filling said container.

Claim 2

Dependent Claim 109 words

An article of manufacture comprising a deformable container having a capped extrusion orifice, said container being filled with a chewing gum composition, said composition being resistant to syneresis over protracted storage periods and being extrudable under ambient temperature conditions, said composition including gum base, sweetener, about 11% or more water by weight, and an activated, thermally reversible solution of a gelling agent, said gel solution being solid at ambient temperatures said gum composition having been introduced into said container at a temperature above the reversal temperature of said gel composition by an extrusion process thereby to introduce laminar flow in said composition in the course of filling said container.

Claim 3

Dependent Claim 15 words

An article in accordance with claim 1 wherein said gum base incorporates poly vinyl acetate.

Claim 4

Dependent Claim 31 words

An article in accordance with claim 2 wherein said poly vinyl acetate is present in the range of from about 2 to about 6% by weight of said chewing gum composition.

Claim 5

Dependent Claim 25 words

An article in accordance with claim 1 wherein said gelling agent is selected from the group consisting of xanthan, guar, locust bean, carageenen and pectin.

Claim 6

Independent Claim 114 words

The method of manufacturing an extrudable chewing gum in a deformable container having an extrusion orifice, comprising dissolving thermally reversible gelling agent in water and heating the solution to a temperature above the activating temperature of said gelling agent to provide a solution which, at ambient temperatures, will form a thermally reversible gel, admixing said activated solution with a mixture of gum base and sweetening agent in an amount sufficient to form a chewing gum composition including at least about 11% free water, and thereafter extruding said gum composition into a deformable container having a cappable extrusion orifice while maintaining said composition at a temperature above the reversal temperature of said gel forming solution.

Claim 7

Independent Claim 114 words

The method of manufacturing an extrudable chewing gum in a deformable container having an extrusion orifice, comprising dissolving thermally reversible gelling agent in water and heating the solution to a temperature above the activating temperature of said gelling agent to provide a solution which, at ambient temperatures, will form a thermally reversible gel, admixing said activated solution with a mixture of gum base and sweetening agent in an amount sufficient to form a chewing gum composition including at least about 11% free water, and thereafter extruding said gum composition into a deformable container having a cappable extrusion orifice while maintaining said composition at a temperature above the reversal temperature of said gel forming solution.

Claim 8

Dependent Claim 32 words

The method in accordance with claim 5 wherein said gelling agent is selected from among the class consisting of one or more of the following: xanthan, guar, locust bean, carageenen and pectin.

Claim 9

Dependent Claim 31 words

The method in accordance with claim 5 wherein said gum base incorporates poly vinyl acetate in the range of from about 2 to 6% by weight of the final gum composition.

Claim 10

Dependent Claim 28 words

The method in accordance with claim 7 wherein said gum formulation includes by weight from about 3.8 to 20% corn syrup and from about 52 to 62% sucrose.

Claim 11

Independent Claim 144 words

The method of fabricating a chewing gum which is extrudable at ambient temperature conditions, includes about 11 to 13% free water and is resistant to syneresis over protracted storage periods, comprising forming a gum by mixing by weight, about 16 to 20% gum base, sweeteners and flavorants, adding to said gum a solution of a heat activated thermally reversible gelling agent, said gelling agent being present in said solution in quantity sufficient to convert said solution to a gel state at ambient temperatures, said solution having a temperature above the activating range of said gel, blending the gum and gel solution admixture while maintaining the temperature thereof above the reversal temperature of said gel solution, and extruding an increment of said admixture into a deformable dispenser having a capable extrusion orifice, said extrusion step being effected while said increment is above said reversal temperature.

Claim 12

Independent Claim 144 words

The method of fabricating a chewing gum which is extrudable at ambient temperature conditions, includes about 11 to 13% free water and is resistant to syneresis over protracted storage periods, comprising forming a gum by mixing by weight, about 16 to 20% gum base, sweeteners and flavorants, adding to said gum a solution of a heat activated thermally reversible gelling agent, said gelling agent being present in said solution in quantity sufficient to convert said solution to a gel state at ambient temperatures, said solution having a temperature above the activating range of said gel, blending the gum and gel solution admixture while maintaining the temperature thereof above the reversal temperature of said gel solution, and extruding an increment of said admixture into a deformable dispenser having a capable extrusion orifice, said extrusion step being effected while said increment is above said reversal temperature.

Claim 13

Dependent Claim 13 words

An article of manufacture made in accordance with the process of claim 9.
