Description

In another particular aspect, narrowing the open end of the cylindrical container into the neck portion further comprises applying pressure perpendicular to the axis of the cylindrical container adjacent to the open end .

In step 404, a sheet metal is formed into a cup shape. The cup is then drawn into a cylindrical container at step 406. The cylindrical container has an open end and a closed end. In step 408, a concave bottom portion is formed at the closed end of the cylindrical container. In some embodiments, the open end is trimmed for a straight edge before narrowing the open end into the neck portion. In step 410, a decorative coating and sealer is applied to the cup. In some embodiments, a layer of paint may be applied on the outer surface of the stretch bottle 100 and a layer of transparent sealer 119 may be further applied on the layer of paint. A sealer film 130 may be applied on the inner surface of the stretch bottle 100 to separate the drink from the sheet metal. In step 412, the cylindrical container may be heat treated to remove some or all of the work hardening effect experienced in the previous step and to dry the decorative coating or sealer applied to the cup. In Step 41 4, the neck portion is formed adjacent to the opening 123 of cylindrical container 100. The neck portion 105 may be formed in a necking operation and may have a varying diameter that forms a tapered contour 107 that narrows.

In some embodiments, the temperature set point and cycle period during step 412 are configured to cure any decorative coating applied to the bottle and to thermally recover the metal. For example, the coated bottle 100 may pass through a washer drying oven, a pin oven, and a baking oven. In some embodiments, the coated bottle 100 may travel through a washer drying oven at about 275-500 ° F. at about 5-17 ft / min. The coated bottle 100 may then move through a pin oven at about 390-500 ° F. at a rate of about 200-1500 cans / minute. Finally, the coated bottle 100 may move through the baking oven at a maximum speed of about 12-22 ft / min. The oven internal temperature may be about 290-340 ° F. in the first zone, 410-500 ° F. in the second zone, and 400-500 ° F. in the third zone.
