1. A receptacle for pharmaceutical packaging, 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, an elongate barrel section length LB being a distance between pA and pB;
a side wall extending over the elongate barrel section, the side wall having an inner surface bordering an interior, the interior having a diameter; and
a layer of a lubricant located on at least a part of the inner surface, at a given axial position p on the axis between pA and pB, a thickness of the 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, a portion X of the axis extends from a first axial position p1 to a second axial position p2 such that the following criteria are satisfied:
both the first axial position p1 and the second axial position p2 lie between pA and pB;
a portion length LX is a distance between the first axial position p1 and the second axial position p2;
the portion length LX is at least a half of the elongate barrel section length LB; and
the layer extends over the entire portion X; a mean thickness Tmean of the layer is determined in the portion X; a position pm is the midpoint between p1 and p2; TA is a mean thickness of the layer for a section from p1 to pm; TB is a mean thickness of the layer for a section from pm to p2; a ratio TA:TB is in a range from 5:1 to 1:5; wherein the layer has a maximum layer thickness Tmax determined between p1 and p2, a minimum layer thickness Tmin determined between p1 and p2 and a value of Tmin/Tmax is at least 0.7, and one or more criteria are satisfied, the criteria being selected from the group consisting of:
the elongate barrel section length LB is in a range from 3 cm to 20 cm;
a mean value of the diameter of the interior determined over the range pA to pB is in a range from 0.4 cm to 4 cm;
a mean thickness of the sidewall determined over the range pA to pB is in a range from 0.3 mm to 4 mm; and
a volume of the interior is in a range from 0.1 mL to 150 mL.
