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 , 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 , 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. <EOS>
