Abstract (en)
[origin: CA2117420A1] Lightweight containers such as polyethylene terephthalate (PET) beverage bottles (20) are rendered stable for conveyance on a horizontal conveyor (40) by temporary addition of water ballast (44). The b allast (44) is drained during washing/rinsing steps and thus does not add to the permanent weight of the bottle. Ballast in th e amount of about 2 to 10% of the bottle volume is sufficient to enable increased production line speed with fewer bottle jams due to the lightweight bottles falling over. The ballast may be added in an amount of 50 to 150 % of the empty container weight for a typ ical container, thus filling the bottle only 0.5 to 1.5 inches at the bottom. The bottles are arranged upright, for example at a dep alletizer (30), and loaded with ballast from a reservoir or pressurized supply of water. The bottles can be loaded in a group and a plura lity of valves (168) having valve bodies (166) on a movable common support open simultaneously. The ballast is removed at the b ottle rinsing station, which inverts the bottles to drain the ballast as well as rinse water.
