Installation

In Blender open Edit, Preferences, Get Extensions, then use Install from Disk and pick the bottle_can_generator zip.

Usage

1. Open the Bottle tab in the 3D viewport sidebar (N). With nothing selected, click the picture to choose one of the 47 designs, or browse the five families, and add it at the 3D cursor. You can also use Shift+A, Mesh, Bottle & Can.
2. The card at the top shows the design, its size in mm, its capacity and its face count. Surprise makes a new random design, Vary changes the current one a little, the label button paints a new label, the palette button picks new colors and the arrow resets the design.
3. The icon tabs hold every setting: Shape (container, size, profile, flutes, ribs, crush), Closure (cap, cork, tab or carton top), Label (label, artwork, lettering), Drink & Wet (drink, foam, bubbles, condensation, frost), Pack (multipacks), Finish (glass, metals, caps, colors) and Export (detail, seed, Convert to Mesh, Delete).
4. To use your own artwork, pick Your Image as the label design and choose an image.

Use Rendered view in Cycles for real refraction in glass and drinks.
