Frequently Asked Questions

UdderLok is skipping the thread when I tighten it, what should I do?2025-02-21T14:00:10+00:00

It may be that the thread type doesn’t match – please see the compatibility image.

You need to gently push it on while turning a quarter-turn anti-clockwise which will make it sit flat, and then screw clockwise to tighten – It’s a snug fit and can take a little practice.

Can someone get the lock off without the key?2025-02-10T12:40:53+00:00

Please screw the lock on tightly. We’ve designed it to allow you to do this without it jumping the thread on the bottle.

How secure is UdderLok?2025-02-10T12:39:37+00:00

We’re all about discouraging theft – it’ll make the office kitchen thief’s life a bit harder so they take someone else’s milk.

Will UdderLok work on milk bottles in my country?2025-02-21T13:58:19+00:00

UdderLok is compatible with supermarket milk bottles in the UK and Anchor Dairy milk cartons in New Zealand – we are hoping to expand our range to other countries soon.

Can I lay the milk down with an UdderLok on?2025-02-21T13:58:58+00:00

We recommend you keep your milk bottles upright.

Where is UdderLok made?2025-02-10T12:31:47+00:00

UdderLok, Load ‘n’ Lok and its packaging are made in Great Britain.

Is it Recyclable?2025-02-10T12:30:52+00:00

Yes – UdderLok is Type 2 HDPE and the Load ‘n’ Lok bottle is Type 7. Our packaging is also fully recyclable and contains recycled materials.

.

Is it dishwasher friendly?2025-02-10T12:27:59+00:00

Yes – UdderLoks are dishwasher friendly – we also tested the durability of a Load ‘n’ Lok bottle in the dishwasher every day for a year and it passed the dishwasher test.

Our Story

Husband and Wife Matthew and Amy, got so fed up of people helping themselves to their milk from the office fridge so they set about designing a lock that’s easy to use, recyclable and dishwasher safe to keep the milk thieves at bay.

Patented in 2021 and made in Keighley, West Yorkshire, Matthew and Amy worked closely with a plastic injection moulding company to get the design off the ground and onto milk bottles. They wanted to keep the manufacture of UdderLok and its packaging components as close as possible to them in Leeds.

2025 saw the introduction of Load ‘n’ Lok, a locking storage bottle, also made in the U.K.

Matthew and Amy are really proud to be a British company working with other British companies.
