Because the tube prevents moisture from leaving. Thus, the glue remains wet. Glue only adheres when it dries. Ultimately, any glue container usually has at least some glue stuck to the inside that isn't usable when the container is otherwise empty, because the moisture seal is not perfect.

The glue requires weathering of thr glue paste so that it can stick at a place. The usual changes taking pace during this period are evaporation of water and contact with air. As the inner part of the tube are out of reach of air for evaporation of matter. Hence, the glue does not stick in the tube itselgf.

Glue may 'stick' to the inner walls of the tube like lather to a human shaver's face because it is viscus. However the glue is protected within the tube and can not set. The glue may need to dry, absorb moisture, interact with oxygen or with another glue component (mixed epoxy) before it can set. Often the cap of the tube may become glued to the tube where the exposed glue sets. The tube material is carefully selected to avoid being dissolved by the glue or initiating the setting process.

glue usually reacts in air and dries. in the tube the glue stays moist and without air to react to and dry. leave the top off the glue bottle and what will happen? theres your answer!
