ABSTRACT:
An extrusion container comprises a main container body with a squeezable outer shell layer and an extrusion cap body, and at least two adhesive bands of longitudinal band form, each of which adheres and fixes together the outer shell layer and an inner layer along the entire height range, wherein the width of each adhesive band is set so as to disable complete closure of the plane cross section by free deformation of non-adhered inner layer parts, and a rigidity of the outer shell layer is set so that, in the state where free deformation of the non-adhered inner layer parts reaches a limit, deformation of the outer shell layer by tension at the non-adhered inner layer parts occurs as a result of normal squeezing operation by a human hand, whereby an extrusion path and smooth extrusion operation is maintained and residual contents is reduced.
