How to Open an Old Milk Can: Tips and Tricks

If you come across an old milk can, you might be stumped on how to open it. Whether you’re handling rusty cans from a dairy background or just curious about the process, there are a few methods you can try to get those lids off. Here’s how:

Understanding the Lid

Old milk cans often have a special type of lid that is press-fit, similar to a cork but made of metal. This type of lid doesn’t need to fit too tightly, as it’s designed to keep the milk inside from leaking out. However, like any metal container, these cans may have rusted in place over time.

Removing the Lid: Traditional Methods

Here’s a step-by-step guide to remove the lid from an old milk can:

Preparation: Start by placing a block of wood under the rim of the lid. Use a hammer to gently tap the lid upward. The idea is to create an upward force to break the seal. Continue Tapping: Move around the edge of the lid, tapping at various points. If the lid doesn’t come off, try this method again with a bit of penetrating oil to loosen the rusted seal. Let the can sit for a day with the oil applied. Strategic Use of a Mallet: If the lid is particularly stuck, use a mallet to gently tap the edges of the lid. A metal hammer is also an option if a wooden or soft-faced hammer isn’t effective.

Opening Modern Cans

Thanks to modern technology, many cans are now filled with evaporated milk and have a ring pull end similar to beverage cans. To open these cans:

Locate the Ring Pull: Find the ring pull tab on the edge of the can. This is usually the area where the lid is sealed, but it can also be a different tab depending on the design. Apply Force: Grab the ring pull and give it a sharp pull. This should pop open the seal and allow you to remove the lid easily. If you’re familiar with drinking cans, this method is quite similar to that.

Conclusion

Whether it’s a ten-gallon can shipped to a creamery or a modern can of evaporated milk, there’s a method to open those pesky lids. Whether using traditional tools or the force of your own hands, you can access the contents of that old milk can with just a bit of patience and the right technique. Happy opening!
