Womens vintage purse acc., Jeweled tube for perfume

I'm sure these little tubes have a specific name, but I'm not sure. It looks like a lipstick tube, but a soft plastic refillable bottle comes out from within. Plunger style top would dispense perfume or lotion. Never used, mint condition! Pearl center, surrounded by clear rhinestones. Goldtone metal case. Shiny like new! I will be listing another one that is similar.
