Abstract
Squeezable plastic tubes which have a flip-top closure cap with a finger recess are provided by a method which aligns indicia on labeling of the tube with the finger recess, the labeling being either a wrap-around label or a label applied on the front and/or back wall of the tube. The indicia is centered on or opposite to a visually desired graphics portion of the label. The closure cap is applied to a collapsible plastic cylinder followed by applying a label such that the indicia is aligned with or opposite to an imaginary surface line which is parallel with the longitudinal axis of the cylinder and passes through the center of the finger recess of the closure cap. The open end of the plastic cylinder, after filling the cylinder with contents to be dispensed therefrom, is sealed in a direction perpendicular to a plane defined by the center of the finger recess and the longitudinal axis, by alignment of sealing means with the indicia, to form a filled squeezable plastic tube.
