ABSTRACT:
A tube includes inner and outer sleeves that can be sealed simultaneously. The inner sleeve is supported in the outer sleeve stably while deformation of the inner sleeve is allowed due to discharge of contents therein. The outer sleeve encloses the inner sleeve to define a space therebetween. A dispenser for discharging the contents out of the inner sleeve includes a cylinder through which the contents is delivered. The dispenser is mounted to the outer sleeve and the cylinder is slidably related to the inner sleeve. Bottom ends of the inner sleeve and the outer sleeve are adhered to each other to define a bottom portion of the inner sleeve. The outer sleeve has at least one passage communicating the space with the outside of the outer sleeve.
