<p>The container, intended for holding and transporting pig sperm for artificial insemination of sows, consists of a tube in a poly-alkylene, in pref. in high or low-density polythene or in poly-propylene, which slightly diverges conically to its open filling end whilst its other end has a shoulder with conically converging central dispensing spout. The dispensing duct of the spout is closed by an integral twist-off element at its end. The shoulder pref. converges to the spout at an angle of approx. 30 deg. The cubic capacity of the open tube may be around 100ml, closure after filling (by peristaltic pump from supply container) being effected by heat welding. Insemination is by pipette filled from the tube.</p> |
