A can crusher is a type of can opener that has a wire that runs through the middle of it, which grabs onto the can and squeezes it closed. This squeezes the can in such a way that all the air is removed, making the can be half empty, which means you can put more in. There is no need to stand on the edge of a can, waiting for the can to open, because it will do the opening for you. Many can openers are made with this type of mechanism, and they are quite popular around the world. There are many models and sizes of can crushers, ranging from the small hand held types to the larger countertop style units. Some of these are even made with a can dispenser attached to it!
The main feature of a can crusher is its squeezing action, which is used to pull out all the air from a can without releasing the contents of it. When the can has no air left inside, the can crusher will start leaving a ‘hole’ in the can, forcing the air out through that hole. Some of these devices will have the wire that runs through the middle to grab onto the can instead of the metal edge, so the can will stay shut while it is being squeezed. These models are much stronger than their hand held counterparts, and it is often much easier to operate.
Hand held can openers are much easier to use, and you will find that they do not work as well as the larger models. If you are interested in saving the environment, then a can crusher is an excellent choice. It can save cans from going into landfills, and it can also help people by keeping them from throwing away cans that they may not be able to use or drinking all the way. Not only can you use these to make the world a smaller place to live in, but they can also save you money!
