1. A container configured to hold a substance and extending along a longitudinal axis, said container comprising:
a container body configured to hold said substance comprising:
a top part;
a closure section being a bottom part of the container body and arranged in an opposite end of the container body compared to said top part, comprising:
a first circular cross-section with a first radius in a plane transverse to said axis;
a second circular cross-section with a second radius in a plane transverse to said axis, wherein said second radius is larger than said first radius; and
an annular wall extending from said second circular cross-section to said first circular cross-section such that said annular wall is formed with an angle alpha in relation to said axis, wherein said closure section is arranged so that said first circular cross-section is closer to said top part along said axis than the second circular cross-section;
a container wall forming sides of said container around the axis and extending from said closure section to said top part, said annular wall of said closure section forming one end of said container wall; and
the container further comprising a sealing structure comprising;
a circular bottom plate configured to seal said container body; and
a sealing wall extending around said circular bottom plate and tilted with said angle alpha in relation to said longitudinal axis, wherein said sealing wall is configured to engage said annular wall, and wherein said sealing structure is configured to be pressed into said closure section to seal said container, and wherein said angle alpha is between 2-8 degrees,
wherein said container body and said sealing structure are made of a molded paper material, and
wherein said top part further comprises;
a spout connected to said container body and configured to deliver said substance to a user; and
a lid element configured to seal said spout, said lid element being made of a molded paper material,
wherein said spout comprises an annular spout wall tilted with a further angle between 2-8 degrees in relation to said longitudinal axis,
wherein said lid element comprises a lid indentation at a central location of the lid element and said lid element is configured to be pressed down on said spout to achieve a seal between said annular spout wall and said lid element; and
wherein said lid indentation comprises an inner wall tilted with the further angle in relation to the longitudinal axis.
