How to purchase a product bundle?

Question:

A bundle product can be sold but I cannot select it in a supplier invoice.
How to purchase it?

Our business case:
A company purchases fluids and gases in containers, then uses them, and returns the containers back to the supplier.

For instance, the argon gas for welding, which is always supplied in 20-liter cylinders.

A customer gets an invoice for consumed argon, say, 5 liters. When the cylinder is empty, they send it back to the supplier and receive money for it.

So, the company purchases a product bundle and sells its combined products separately.

Answer:

Option 1:
In 1C:Drive, there is the Kit processed document that can "split" a product into its components. So, you can purchase a gas cylinder, split it into gas and the cylinder, and then consume (sell) them separately.

Option 2:
Add two separate products to the supplier invoice: 1) gas, 2) cylinder.
