Insulated Sipper Tumbler Support
Find some answers to the most frequently asked questions about your Sippy Cup.
Can my cup be sterilised?
Of course! Our cups are suitable for sterilisation by steam (electric and microwave), by boiling (5 minutes) and by cold water tablet / liquid solution. The only exceptions are our Insulated Sippee and Straw cups, which are only suitable for cold water sterilisation. Stay safe people!
Why is my lovely cup stained?
Tomatoes are usually to blame! If you wash your cup alongside pans or bowls that have had strong coloured sauces in, like tomato or carrot, some of the colour can transfer. This can happen in the sink as well as the dishwasher. To keep your cups looking lovely and new, put them at the front of the queue if you’re washing up by hand, and on the top shelf if you’re using a dishwasher. This usually results in fewer undesirable stains!
Can I put my cup or bottle in the microwave?
In an ideal world, you’d warm your little one’s drink over a stove, stirring to ensure consistent heat throughout, then you’d pour it into their cup. In the real world, if your little one wants a warm drink, you’re probably going to pour the milk or juice into their cup and pop it in the microwave. The good news is that this will not damage our cups (apart from the insulated cups - they don’t get on well with microwaves). The bad news is that microwaves can cause random hot spots, and these are not nice for little ones to swallow. So, if you do use the microwave, please leave the lid off to warm, then pop it on and give the cup a really good shake or swirl before handing it over.
How do I clean the valve?
Firstly, unscrew the lid, taking the valve out. You may need to do this by wiggling the valve from left to right.
Separate the white retainer from the clear silicone, washing all parts thoroughly in warm soapy water, then rinsing in clean water (or use a dishwasher on the top shelf only) after each use. Additionally, our valves are suitable for sterilisation by steam (electric and microwave) or boiling (5 minutes) after the washing process.
We suggest allowing the valve to dry prior to reassembling if storing the cup away.
To re-assemble, connect the clear silicone and white retainer parts together, placing back into the lid, pushing until the sides lock into place.
My cup seems to be leaking, what could be causing this?
Leaking is generally caused by the silicone valve not being assembled correctly. When assembling, ensure that the valve is fully pushed through the white retainer, pushing the stem through the hole until you hear it slightly pop into place. *Note if you do not hear it pop then it isn’t fully in place and may continue to leak. Also, please ensure the small cut in the dome on the silicone valve can open to vent air.
Further guidance on both our straw and spout cups can be found in our assembly instructions.
Are spare lids available?
We’re afraid you can’t buy lids separately, but the good news is that all our cups have interchangeable lids, so it’s easy to swap them around. The only exceptions are our meal time trainer and filter bottle - these have such a distinct design that their lids don’t fit other cups.
Are your cups and beakers dishwasher safe?
Of course! Pop them on the top shelf though. As with all plastic things they can get a bit stained and yucky-looking in the dishwasher (blame that bolognese sauce or carrot soup you had last night). If they do get discoloured there’s nothing to worry about - they’re perfectly safe, they just don’t look as good!
The valve doesn't always stay in position, is there anything I can do?
Firstly, check the valve as it may not be fully assembled. Ensure that the dome and button on the silicone side are fully pushed all the way through the holes on the white retainer.
Can I really interchange lids across your new cup range?
Absolutely! One of the great things about our new cups range is the ability to interchange lids and handles. You can’t swap a lid with a one piece valve with a lid with a two piece valve, you can't use them with the new filter bottle and Lippee cups have their own uniquely designed lid.
Can I use valves from different cups?
The two piece valve can be used across the range, and our new straw cups can also be swapped around. If swapping straw lids, just bear in mind that they all hold different lengths of straw, depending on the size of the cup, so you’ll need to use the right length.
The only thing to watch out for if you’re swapping parts is the two piece valve. This has a new fitment so can’t be used in place of a one piece valves.
