<p>A blow moulded plastics container 10 is provided for storing liquid such as milk, the container comprising a blow moulded body defining a chamber for storing liquid, a base 18 for standing the body in an upright manner, and a part line 20. The base defines a recess 22 extending co-linear with the part line. A rib (30, fig 2a) is formed along a portion of the part line within the recess, the rib extending outwardly within the recess, and a ratio of the width of the rib to the height of the rib along a substantial length of the rib is between about 0.8:1 and about 1.2:1. The rib may have a first end, a second end and a centre portion, and may define at least one shoulder (32, fig 1b) adjacent the rib at the first end and/or the second end of the rib. Two further recesses 34 may be provided each extending substantially perpendicular to the recess 22. The recesses 34 may be substantially tear-drop shaped, each having a narrow end 34a proximal the recess 22. A mould and a method of producing a base is also provided.</p> |
