For a life less annoying…

UdderLok – the milk bottle lock

“Colleagues” too friendly a term for your milk-stealing “Co-workers”?

House “mate” a bit of stretch for that Terry-Tealeaf who denies he’s nicked your semi-skimmed but has never been seen buying a pint in his life?

My Mum has been singing its praises to everyone at work.

Nicola, Birmingham

Thank you so much for this AMAZING product!

Stephen, Lancashire

Not only does it keep my milk safe I get the extra satisfaction knowing that it really winds people up!

Shane, Sheffield

Thank you so much for an awesome product! It’s honestly fantastic. You have made me and my team very happy!

Gemma, Harrow

Great product… Lots of people impressed with it (and a few annoyed!!!) Nothing else out there like it really.

Matthew, Swansea

I’m so happy I found UdderLok!

Andrew, St. Helens

Your product has saved my colleague and I two bottles of milk in one week, I never knew how much we were losing.

Mary, Lincolnshire

I’m very pleased with it and it definitely acts as a deterrent.

Phil, Wythenshaw

I’ve have had an Udderlok for while, forgot to put on the other day and colleagues had emptied a 4 pinter by lunchtime!!!  Worth it’s weight in gold 🙂

Emma, Chester

Is some Udder-plucker
taking your milk?

Locking Lily says “Don’t take it any more – UdderLok – the locking milk-carton cap is here to solve Britain’s most prolific (unreported) crime”

…well, she imagines it probably is

“Are you suffering from a cost of living crisis or rather a cost of thieving crisis? Buy an UdderLok!”

How it Works…

Which milk bottles does UdderLok fit?

UdderLok is compatible with most major supermarket plastic milk containers such as those from Tesco, Morrisons, M&S, Asda, Aldi, Lidl, Co-op & Sainsburys.

It doesn’t fit the plastic milk containers with the annoying little tear-off antitamper tabs.

As it is too big for a Tetrapak-type carton, we’ll soon be selling a refillable and reusable bottle. In the meantime you could always re-use a washed out milk carton.

Frequently asked questions.

Q: How many key/lock combinations are there on offer?
A: There are six different locks/keys – the red UdderLok has the circle key-type, the blue one has the triangles key, the green one squares, the pink one love hearts… because it seemed obvious to us to do that, the lilac one (our favourite) has three kisses and the orange one… orange segments…ok so we’re not going win prizes for originality there. So if your housemate or workmate has an UdderLok already, pick a different colour and they’ll not be able to open yours. Nor you theirs.

Q: What plastic milk bottles does it fit?
A: UdderLok is compatible with most major supermarket plastic milk containers such as those from Tesco, Morrisons, M&S, Asda, Aldi, Lidl, Co-op & Sainsburys. It doesn’t fit the plastic milk containers with the annoying little tear-off anti-tamper tabs. As it is too big for a Tetrapak-type carton, we’ll soon be selling a refillable and reusable bottle. In the meantime you could re-use a washed out milk carton.

Q: Is it dishwasher-friendly?
A: Yes very friendly. And dishwashers properly love it as well. If you don’t have a dishwasher you may be wasting your precious life, but in this circumstance a washing up brush is best for cleaning.

Q: It seems to keep skipping the thread on the bottle when I tighten it
A: Two options here –
#1 The thread type doesn’t match – please see the compatibility images littered across this site
#2 You need to gently push it on, keeping it level before tightening – It’s a snug fit for a good reason and can take a little practice at first

Q: How secure is it
A: We’re all about discouraging theft here… let’s be honest, if your housemate somehow manages to defeat the lock or damages the carton to drain your milk you’re screwed two ways –
1) You’ll be eating dry Frosties, and
2) You’ll have discovered your housemate is even more of a tool than you first thought.

But otherwise it’ll make the little Terry Tealeaf’s life a bit harder so they nick someone else’s milk, which is what it’s all about.

Q: Is it recyclable?
A: Yes it is – it’s made of Type 2 HDPE … but we’re not sure why you ask as we expect you’ll want to keep reusing it for years. Otherwise feel free to responsibly recycle it and buy more from us – we like making a living so shop away. Our packaging is also fully recyclable and the blister-pack contains recycled materials. We also post out in recyclable padded envelopes.

Q: Can you refund if I send it straight back?
A: As it’s for use with food and we cannot tell if it has been used, we can’t refund if you’ve just changed your mind. However, if it’s not working right do tell us and we’ll see what we can do to help. We’re nice like that. One of us used to work in customer service. Not so much the other one, so it’s a bit Russian-roulette if you do complain. See our T&Cs for more info.

Q: Do you like customer suggestions for other products?
A: Absolutely, as long as they’re not terrible ideas. We’ve got a massive bin here though in case they are bad, so knock yourselves out writing to us anyway.

Q: Is it made in Britain
A: It is indeed. British design. British manufactured. The recycled bits of plastic in the packaging are from British recycled waste and the other plastic might be from British dinosaurs but we’ve no reliable way of checking this.

Q: Someone managed take mine off without the key
A: You do need to screw it on tightly to avoid this. We’ve designed it to allow you to do this without it jumping the thread on the bottle. If someone has managed to get it off and you want to know who that is, either search immediately for someone covered in exploded milk spatter, or leave it until later and see which of your colleagues smells like yoghurt. 

Q: Can I lay the milk down with this cap screwed on it?
A: Only if you do that currently with your open milk cartons…. And of course if you enjoy using the salad drawer as a drinking receptacle. Probably best to keep it upright.

Q: Customer question “I’d like to make mildly threatening overtures towards my house co-habitees and co-workers – can you help?”
A: We are now offering free downloads of posters to stick on your fridge to ward people off stealing your milk. They are totally free to print out and use but on a rare serious note, you mustn’t use our logos, characters company or product names in any format other than these downloadable posters as these are owned by us. Basically don’t frig around with them please.
