A bottom dispensing package for a flowable composition, comprising a squeezable container for housing the flowable composition, a base element that is fixed to the container, whereby the base element comprises an orifice whereby the orifice is placed in the direction of gravity beneath the container when the dispensing package is placed in its head-stand position on the base element, whereby the base element further comprises a closure connected to the base element and the closure can be moved back and forth between a closed position in which the closure closes the orifice and an open position in which the composition can be released through the orifice, wherein the base element has a circumferentially closed first contact surface with the container, and/or the container has a circumferentially closed second contact surface with the base element, characterised in that the first contact surface and/or the second contact surface comprises a plurality of mainly parallelly arranged micro sealing lips which extend in orthogonal direction from the first contact surface of the base element and/or from the second contact surface of the container, whereby in a cross-sectional view the micro sealing lips having a tapering contour extending in the direction out of the contact surface (13,24), whereby the micro sealing lips having a lip height > 0,5 μm, preferably between 0,5-50 μm, and the micro sealing lips show a circumferential length which extend from 10%-100% over the circumferentially closed contact surface, and the circumferential length of the micro sealing lips is aligned between +-75-135° to the joining direction of the base element and the container whereby the circumferentially closed first contact surface und/or the second contact surface show(s) a micro sealing lip density > 10, preferably between 50-500 micro sealing lips per cm 2 and the micro sealing lips comprise an E-Module < 2000 MPa, preferably between 500 and 1500 MPa. a squeezable container for housing the flowable composition, a base element that is fixed to the container, whereby the base element comprises an orifice whereby the orifice is placed in the direction of gravity beneath the container when the dispensing package is placed in its head-stand position on the base element, whereby the base element further comprises a closure connected to the base element and the closure can be moved back and forth between a closed position in which the closure closes the orifice and an open position in which the composition can be released through the orifice, wherein the base element has a circumferentially closed first contact surface with the container, and/or the container has a circumferentially closed second contact surface with the base element, characterised in that the first contact surface and/or the second contact surface comprises a plurality of mainly parallelly arranged micro sealing lips which extend in orthogonal direction from the first contact surface of the base element and/or from the second contact surface of the container, whereby in a cross-sectional view the micro sealing lips having a tapering contour extending in the direction out of the contact surface (13,24), whereby the micro sealing lips having a lip height > 0,5 μm, preferably between 0,5-50 μm, and the micro sealing lips show a circumferential length which extend from 10%-100% over the circumferentially closed contact surface, and the circumferential length of the micro sealing lips is aligned between +-75-135° to the joining direction of the base element and the container whereby the circumferentially closed first contact surface und/or the second contact surface show(s) a micro sealing lip density > 10, preferably between 50-500 micro sealing lips per cm 2 and the micro sealing lips comprise an E-Module < 2000 MPa, preferably between 500 and 1500 MPa.
