A trigger is sequentially operated to advance the glue stick. The heater assembly transforms the glue stick into molten glue which is dispensed through a frontal nozzle of the glue gun. The glue gun has a temperature indicator. The glue gun is exteriorly ergonomically configured for facile usage. ## Claims ### Claim 1 A glue gun comprising: a housing having a forward dispensing tip and a rear receiver and enclosing a glue stick receiving/advancing path and a heater and defining a central axis, and said housing has a top and said top defines a recess dimensioned to receive and retain a glue stick;

a handle extending from said housing at a connecting portion at an acute angle forwardly canted to said central axis wherein a distal portion of said handle is forwardly positioned relative to said connecting portion toward said forward tip; and a trigger manually actuatable to advance a received glue stick along said path; so that when a glue stick is received in said rear receiver and advanced along said path and said glue stick is heated by said heater to form molten glue, said trigger is actuatable to dispense molten glue through said tip. ### Claim 13 (depends on 12) The glue gun of claim 12 wherein said stand has a bifurcated leg configuration. ### Claim 14 A glue gun comprising: a housing having a forward dispensing tip and a rear receiver and enclosing a glue stick receiving/advancing path and a heater and defining a central axis; a handle extending from said housing at a connecting portion at an acute angle forwardly canted to said central axis wherein a distal portion of said handle is forwardly positioned relative to said connecting portion toward said forward tip wherein said handle is positionable at a plurality of angles relative to said central axis; and a trigger manually actuatable to advance a received glue stick along said path; so that when a glue stick is received in said receiver and advanced along said path and said glue stick is heated by said heater to form molten glue, said trigger is actuatable to dispense molten glue through said tip. ### Claim 15 (depends on 14) The glue gun of claim 14 further comprising an indexing mechanism which fixes a plurality of stable angular positions of the handle. ### Claim 16 A glue gun comprising: a housing having a forward dispensing tip and a rear receiver and enclosing a glue stick receiving/advancing path and a heater and defining a central axis; a handle extending from said housing at a connecting portion at an acute angle forwardly canted to said central axis wherein a distal portion of said handle is forwardly positioned relative to said connecting portion toward said forward tip; a trigger manually actuatable to advance a received glue stick along said path and further comprising a rotatable dosage guide which adjusts an effective advance of a glue stick when the trigger is actuated; so that when a glue stick is received in said rear receiver and advanced along said path and said glue stick is heated by said heater to form molten glue, said trigger is actuatable to dispense molten glue through said tip. ### Claim 17 (depends on 16) The glue gun of claim 16 wherein said housing has a top and said top defines a recess dimensioned to receive and retain a glue stick. ### Claim 18 A glue gun comprising: a housing having a forward dispensing tip and a rear receiver which receives a glue stick and enclosing a glue stick receiving/advancing path and a heater and defining a central axis, said dispensing tip having a nozzle and said nozzle changes color to indicate that the glue stick is sufficiently heated; a handle extending from said housing at an angle canted to said central axis toward said forward tip; a trigger manually axially actuatable to sequentially advance the glue stick along said path; so that when said glue stick is received in said path and said glue stick is heated by said heater to form molten glue, said trigger is actuatable to dispense molten glue through said tip. ### Claim 19 (depends on 18) The glue gun of claim 18 wherein said housing has a top and said top defines a recess dimensioned to receive and retain a glue stick. ### Claim 20 (depends on 18) The glue gun of claim 18 further comprising an illuminatable indicator indicates that the glue gun heater is connected to power and indicates that the glue stick is sufficiently heated for dispensing glue. ### Claim 21 (depends on 20) The glue gun of claim 20 wherein said indicator emits light at a first frequency when the heater is warming up and at a second frequency when the heater attains a glue dispensing temperature. ### Claim 22 (depends on 18) The glue gun of claim 18 further comprising a control switch selects a low temperature or a full temperature for said heater. ### Claim 23 (depends on 18) The glue gun of claim 18 further comprising a power cord communicating with said heater. ### Claim 24 (depends on 18) The glue gun of claim 18 wherein the trigger connects via linkage with a glue stick feeder which advances the glue stick toward the tip. ### Claim 25 A glue gun comprising: a housing having a forward dispensing tip and a rear receiver and enclosing a glue stick receiving/advancing path and a heater and defining a central axis, said housing having a top, and said top defines a recessed structure dimensioned to retain at least one glue stick;
