The present disclosure relates to a method for manufacturing a nestable water tank, the method comprising molding a water tank comprising a hollow cylindrical body and cutting the water tank to form the nestable water tank comprising a tank body and a lid, wherein the tank body comprises: a side wall comprising a cylindrical shape running along a vertical axis, an interior surface, and an exterior surface; and a bottom connected to a bottom portion of the cylindrical tank, together forming a nestable water tank interior space capable of storing water within the nestable water tank interior space and comprising an interior bottom surface and an exterior bottom surface, wherein at least one of the tank body and the lid are each nestable with other similarly shaped tank bodies and lids.

This disclosure provides a method of manufacturing a polymer container according to a blow molding or stretch blow molding process, in which the base of the blow mold has at least one orifice for pressurized gas to enter the blow mold through the base. Introducing pressurized gas through the orifice in the blow mold base provides cooling assistance within the gas mold, much earlier than the cooling using conventional methods, which can reduce or eliminate the need for any post mold cooling. This method has been found to be applicable to non-hot fill application bottle and container manufacture.

A method for packaging liquid products under pressure in thermoplastic containers includes blow-molding a container from a sterilized preform, exposing an exterior of the container to a mixture that includes liquid coolant and either a sterilizing agent or a disinfectant, pressure-filling the container with liquid product, and sealing the filled container.
