Oberni Tritran Sippy Non-Spill Baby Water Bottle (Tritan training cup) – Leakproof straw cup for 12M+
Product description
Quick overview
If you’re trying to move away from a classic bottle, a leakproof sippy can make the day-to-day much less stressful. The Oberni Tritran Sippy is built for babies and toddlers aged 12M+ who need something that can cope with real life: tipping, lying down, and the occasional “oops” on the move.
On paper, it ticks several practical boxes at once. There’s a weighted straw designed to move with the liquid, so your child can sip when the cup is held upright, on their side, or even when lying down. There’s also a V-shaped valve spout that’s described as leakproof, designed to open only when your tot’s lips touch it.
What stands out in use
The idea here is simple: keep drinking comfortable and minimise spills. The straw being weighted is the main functional detail worth noticing. Instead of the straw “staying put” and leaving your child to drink from the wrong angle, it tends to follow the liquid level, which can help during typical messy phases when kids aren’t steady yet.
The other thing you’ll notice is the valve spout approach. Because it’s designed to open only on contact with lips, the cup is meant to reduce leaks even when tipped over. It’s still a training cup, not a magic bubble—if it’s knocked around with the valve fully engaged in a way you wouldn’t expect in normal sipping, you may still want to treat it like a cup, not a sealed bottle.
A small but thoughtful touch is the anti-slip handle and the included removable carrying strap, which makes it easier to manage in a bag for outings or day trips.
Materials and safety: what you should know
This sippy cup is made from Tritan, described as ultra-durable, crystal clear, lightweight, and produced using Tritan from Eastman. It’s also stated to be BPA-free and non-toxic.
For many parents, “material matters” isn’t just a buzzword—it’s about choosing something you’ll feel comfortable washing repeatedly and letting a child handle every day. The fact that the bottle is clear can also be useful for you: you can usually spot what’s going on inside without guessing.
Cleaning and parts: easier than it sounds
One of the more convincing points is how it’s designed to come apart. The wide-neck cup parts are removable, and you can disassemble and reassemble the handle, weighted straw, and spout.
That matters because weighted straw cups can be the ones that frustrate people during cleaning—if you can’t reach properly, residue becomes an ongoing hassle. Here, the design is geared towards making sterilising and cleaning straightforward.
Who it suits (and who should pause)
It’s a good fit if you’re looking for a leakproof training cup for a child aged 12M+ and you want something that supports drinking in different positions (standing, sitting, or lying down). The “transition” angle also makes sense if you’re trying to go from bottle or breast to cup, while still using a familiar kind of routine.
It may not be the best match if you’re after a fully sealed, spill-proof travel bottle in every scenario. Even with a leakproof valve design, no sippy cup is truly indestructible against rough handling. It also might feel overkill if your child is already a confident cup drinker and you mainly need something very basic.
