1. A metering dispenser comprising:
a body comprising:
a first end;
a second end opposite from the first end; and
a chamber between the first end and the second end;
a plunger within the chamber and movable between the first end and the second end; and
a drive screw comprising an elongated shaft defining an end of the drive screw and extending into the chamber, and wherein the elongated shaft comprises:
a first portion within the chamber and having at least one external thread extending continuously around a circumference of the elongated shaft and continuously along at least a portion of a length of the drive screw, the at least one external thread of the first portion of the elongated shaft having a fused or blocked portion and an unfused or unblocked portion, wherein the unfused or unblocked portion permits travelling of the plunger on the drive screw; and
a second portion within the chamber between the first portion and the end of the drive screw, wherein the second portion is unthreaded, and wherein the fused or blocked portion of the at least one external thread is adjacent to the second portion of the drive screw and between the unfused or unblocked portion of the at least one external thread and the second portion of the drive screw, and wherein the fused or blocked portion prevents travelling of the plunger from the unfused or unblocked portion of the at least one external thread onto the second portion,
wherein movement of the drive screw moves the plunger along an axis within the chamber between the first end and the second end.
