In most flights that I've been on, there are all kinds of bags of varying size and shape. I personally use a little clear zipper bag that you get when you buy a set of small airline approved toiletries or containers.
Since you have these items organized in your carry-on, you probably have them in a bag already. If it was a clear bag, you're all set. If not, I'd still give it a try, just remember to take it out of your carry-on. Worst case is you have to go get a little baggie by the wall over there (!) and put your stuff in it. I've never seen anyone complain about the size or shape of the bag, but always the full size bottles of sunscreen, shampoo, lotion or toothpaste that people still insist on bringing. Don't be that person. Get smaller travel sized items or buy it when you get there.
There have even been times when I forgot to take the bag out of my carry-on and didn't get stopped. And I'm a person that refuses the cancer scanner!
Basically, if you make it convenient for them to see what kind of liquids/gels/etc (usually toiletries) you're bringing with you without them having to open your bag the less hassle you'll get. If you have all the correct sizes of things, they should all pretty much fit, and again, the less hassle you'll get. Not even a second look, I guarantee.
Having to open your carry-on will just cause a delay for everyone else down the line and that's why you will want to take it out. Having items like that in your bag might also invite you to a pat down, cuz that's how we roll here now.
Happy Flying :)
