Vacuum Flask Price Per Litre November 2026: Rs. 800 Against Rs. 1,199

A vacuum flask is one of the few homeware items that publishes a number you can divide by: its capacity, printed in millilitres in almost every listing title. We read both shelves on 7 November 2026, logged out, from India — 35 distinct listings from Tata CLiQ's own product API, 101 from Flipkart's own search data.

Flipkart states a capacity on 100 of its 101 listings; Tata CLiQ on 23 of 35. Dividing price by that figure: Flipkart runs Rs. 202 to Rs. 3,069 a litre with a median of Rs. 800; Tata CLiQ runs Rs. 548 to Rs. 2,526 with a median of Rs. 1,199.

Unlike some cross-retailer reads, these two ranges genuinely overlap — Flipkart's dearest flask per litre is dearer than anything on Tata CLiQ. So the honest claim here is about the middle of each shelf, not about every listing on it.

Borosil is effectively a full-price brand on Tata CLiQ. Eleven listings between Rs. 899 and Rs. 1,263, and not one of them badged above 10%. Six of the eleven badge 4% or less. Flipkart's single Borosil listing sells at Rs. 628 and badges 22%.

Milton is the sharper illustration. Tata CLiQ carries two Milton Eiffel 1000 flasks, both at Rs. 499 against a stated Rs. 505 — a reference price six rupees above the asking price, which renders as 1% off. Flipkart carries 22 Milton listings between Rs. 312 and Rs. 491, badged 15% to 31%.

This is not evidence that Tata CLiQ is overcharging. A 1% badge on a Rs. 499 flask is a retailer declining to inflate a reference price, which is the opposite of the behaviour we criticise on other shelves. It does mean that on this category, a discount percentage will not help you choose between these two sites — the numbers measure different things.

Read the bottom of that table before you trust the top of it. The dearest flask per litre in either read is a Milton Elfin 160, a 160 ml pocket flask at Rs. 452. It is not a bad buy; it is a small object, and dividing by a small number produces a large one. Per-litre pricing structurally penalises small flasks, and the same effect puts a 350 ml Bergner at Rs. 2,197 a litre.

The figure is useful at the other end. A 2,000 ml Freelance on Tata CLiQ at Rs. 1,889 works out at Rs. 944 a litre — cheaper per litre than most of that shelf despite being its second-dearest item. If you are buying for a household or a journey rather than a desk, capacity is what you are paying for and this is the column to read.

What per litre cannot see: stated insulation hours, steel grade, lid design, leak-proofing or whether the thing survives a drop. None of that was tested, and nothing on either page was filled.

The rating rows are the widest gap on the page. Tata CLiQ publishes a rating on 21 of 35 listings and its largest rating count in the whole read is 9. Flipkart publishes on 87 of 101 and reaches 67,165 on one steel bottle and 49,033 on a Milton Elfin.

So the two sites are good at different things on this shelf. Tata CLiQ carries a deeper Borosil and Jaypee Plus range at steady, honest prices with almost no published feedback. Flipkart carries far more choice, deeper discounts against larger stated prices, and tens of thousands of ratings to read. If the flask matters, that last column is worth more than the badge.

• It compares medians, not every listing. The per-litre ranges overlap, and Flipkart holds both the cheapest and the dearest per litre.
• It makes no like-for-like product comparison. Only two brands appear on both shelves and no single model was matched across them.
• It does not test insulation. "24 hours hot", "double wall" and "thermosteel" are the sellers' own words.
• It excludes coupons, bank offers and delivery charges, all of which move these numbers. Both reads were made logged out.
• Tata CLiQ's low badges are reported as low badges, not as poor value. A 1% badge on a Rs. 499 flask reflects an uninflated reference price.
