Abstract
Provided are a tube container having a shutoff function on a shoulder and a neck and a method of manufacturing the same, in which a head gas barrier layer formed of an aluminum sheet is bonded to inner surfaces of the shoulder and the neck serving as a head to correspond to the inner surfaces according to formation of the head, and thus the shutoff function is provided to prevent chemical changes in even a shoulder and neck portion due to external environmental factors, so that contents filled in the tube container are prevented from decaying or deteriorating, and intrinsic ingredients of the contents are prevented from being lost for a long time. Accordingly, the contents are prevented from decaying or deteriorating due to the external environmental factors, and the intrinsic ingredients of the contents are used for a long time without losing the intrinsic ingredients.
