If you can’t hand your urine sample in within an hour, you should keep it in the fridge at around 4C (39F) for no longer than 24 hours. Put the container of urine in a sealed plastic bag first.

Can you reuse a urine sample container?
Specimen containers should not be reused. The NCCLS guidelines for urine, GP-16A2, recommend the use of a primary collection container that holds at least 50 mL, has a wide base and an opening of at least 4 cm. The wide base prevents spillage and a 4 cm opening is an adequate target for urine collection.
