ABSTRACT:
A tube squeezer that is replaceably attachable to a tube with contents and prevents the contents of the tube from flowing backwards therein when the tube is no longer squeezed and thereby allowing the contents of the tube to be readily and constantly available without waste. The squeezer includes a lower portion and an upper portion. The lower portion has two pair of vertically-disposed legs with inboard surfaces that oppose each other and define a longitudinal space therebetween. The lower portion further has a lateral space between each pair of legs at the pair of lateral sides of the lower portion. The top surface of the lower portion has a groove. The upper portion is replaceably interlocked with the lower portion. The upper portion further has a pair of tabs, each of which releasibly and frictionally engages its respective lateral space in the lower portion when the upper portion is interlocked with the lower portion. The bottom surface of the upper portion has a pair of longitudinally-disposed tabs, each of which releasibly and frictionally engages its respective longitudinal space in the lower portion when the upper portion is interlocked with the lower portion, and terminates in ends that releasably and frictionally engage the inboard surfaces of the two pair of legs of the lower portion when the upper portion is interlocked with the lower portion.
