Claim 18:
19. A process for preparing a disposal product, the process comprising:
providing a receptacle, the receptacle comprising:
an elongate barrel section having a direction of elongate extension and an axis in the direction of elongate extension, an axial position p being determined along the axis, the elongate barrel section extending from an axial position pA to an axial position pB, the elongate barrel section defining a barrel length LB which is the distance between pA and pB;
a first end closer to the axial position pA than to the axial position pB;
a second end closer to the axial position pB than to the axial position pA;

a first aperture at the first end that has a first aperture diameter;
a second aperture at the second end that has a second aperture diameter, the first aperture diameter is greater than the second aperture diameter;
a plurality of side walls extending over the elongate barrel section, the side walls each having an inner surface bordering an interior, the interior having a diameter;
a layer of a lubricant located on at least a part of the inner surface, wherein, at a given axial position p on the axis between the axial position pA and the axial position pB, a thickness of each side wall, a thickness of the layer, and the diameter of the interior are each determined as an angular mean in a cross-sectional plane perpendicular to the axis at the axial position p; and
a charge present in the interior and sealing a cross section of the interior between the inner surfaces of the side walls, an axial position p+ being the axial position closest to the axial position pB at which the charge contacts the layer or the inner surfaces and an axial position p− being the axial position closest to the axial position pA at which the charge contacts the layer or the inner surfaces, a value of the distance between the axial position pB and the axial position p+ divided by the distance between the axial position p+ and the axial position pA is in a range from 0 to 2, a mean thickness of the layer determined between the axial position pA and the axial position p. is at least 10 nm, wherein at least one criteria is satisfied, the at least one criteria being selected from the group consisting of:
the length LB is in a range from 3 cm to 20 cm;
a mean value of the diameter of the interior determined over a range from the axial position pA to the axial position pB is in a range from 0.4 cm to 4 cm;
a mean thickness of one of the sidewalls determined over a range from the axial position pA to the axial position pB is in a range from 0.3 mm to 4.5 mm; and

the volume of the interior is in a range from 0.1 to 150 ml; and
converting the receptacle into the disposal product.
