20 Litre Water Can vs Jar vs Bottle: What's the Difference?
Quick answer: a "water can", a "water jar", and a "20 litre bottle" usually mean the same thing — a 20-litre refillable container of packaged drinking water. "Can" is simply the everyday word in most of South and East India (including Kolkata), while "jar" is the word suppliers and the industry use. The real differences that matter are dispenser compatibility and size variants, covered below.
Search for water online and the words blur together: "20 ltr water can", "water jar delivery", "20 litre bottle". If you have wondered whether these are different products with different prices — they almost never are. Here is the plain-language map.
Same product, three names
| Word you search | What suppliers call it | Notes |
|---|---|---|
| Water can / 20 ltr can | 20 litre jar | The everyday word in Kolkata, Chennai, Hyderabad and most of the south and east |
| Water jar | 20 litre jar / bubble top jar | The industry and B2B term; "bubble top" refers to the neck style used on dispensers |
| 20 litre bottle | 20L packaged drinking water | Often used interchangeably, though "bottle" more often means the small retail sizes |
| Bisleri / kinley (brand as generic) | Packaged drinking water | Some buyers use brand names generically — suppliers still deliver their own brand |
The differences that actually matter
1. Dispenser compatibility
Standard 20 litre jars are made to fit water dispensers, but neck styles differ (wide-mouth vs bubble-top). If the jar is for a dispenser, say so when ordering — your supplier should match the neck type.
2. Retail bottles vs jars
Small bottles (250ml–2L) are single-use retail packs; the 20 litre jar is a returnable, refillable container. For offices and households with a dispenser, the jar is the economical standard; for events and guests, small bottles are convenient.
3. What is inside
Whatever the container is called, the water must meet the same legal standard: packaged drinking water sold in India requires an FSSAI licence, and since 1 January 2026 manufacturers must test monthly under FSSAI's Scheme of Testing. Check the label, not the nickname — our label guide shows the seven checks.
4. Deposit and exchange
Returnable jars usually involve a refundable deposit and an exchange-for-exchange swap on delivery. Terms vary by supplier — ask before your first order.
