'Deckel' (lid) is closely related to the verb 'decken' (to cover), which means 'bedecken' (to cover) or 'zudecken' (to cover up). A 'Deckel' is therefore literally an object that covers something.
Bitte decke den Salat mit einem Deckel ab, damit er frisch bleibt.
Please cover the salad with a lid so it stays fresh.
There is the well-known saying 'Auf jeden Topf passt ein Deckel' (there is a lid for every pot). It means that there is a suitable partner for every person.
Mach dir keine Sorgen, du findest schon jemanden. Auf jeden Topf passt ein Deckel.
Don't worry, you'll find someone. There is a lid for every pot.
In its literal meaning, 'Deckel' (lid) is often combined with containers. Typical phrases are 'den Deckel auf den Topf legen' (to put the lid on the pot), 'den Deckel einer Flasche zuschrauben' (to screw on the cap of a bottle), or 'den Deckel einer Kiste öffnen' (to open the lid of a box).
Kannst du mir helfen, den Deckel von diesem Glas zu bekommen?
Can you help me get the lid off this jar?
The figurative meaning 'Obergrenze' (upper limit) is used almost exclusively in political or economic discussions. It is often used as part of a compound such as 'Mietendeckel' (rent cap) or 'Preisdeckel' (price cap).
Die Einführung eines Mietendeckels wird kontrovers diskutiert.
The introduction of a rent cap is being discussed controversially.
The meaning 'Rechnung' (bill) for 'Deckel' is colloquial. It is mainly used in informal situations in a pub or restaurant.

border / limit
'Grenze' and 'Deckel' can both mean a limit. 'Grenze' is the general and neutral term for the end of a range or a possibility. In this meaning, 'Deckel' is colloquial and refers to a fixed upper limit or cap, often for money, prices, or costs. The words can be confused because both say that something should not go further or should not become higher. In factual texts, 'Grenze' is usually more natural; for costs, you often hear 'Deckel', for example 'Mietdeckel' (rent cap) or 'Preisdeckel' (price cap).

Die Stadt will einen Deckel für die Mieten einführen.
