Anti yellowjacket cover

As it just happend to my partner, a yellowjacket was inside the can and unseen, so he was hit twice and survived thanks he had no allergy. To prevent this in future I just designed a cover to stop yellowjackets from entering the can.
You might adjust the size as I designed it for the german Red Bull cola, and I dont know if there are different sizes, or you might use of course for different drinks. Very helpful not only for preventing yellowjackets to get into you drink.
