Patent 11607621 was granted and assigned to Mattel on March, 2023 by the United States Patent and Trademark Office.
A toy figurine and/or toy figurine packaging is coated with a dissolvable layer. When the toy figurine is coated, the toy figurine is entirely coated so that its overall appearance, including its skin complexion and/or facial features, is substantially hidden or obscured. Then, when the figurine is submerged in a fluid, the dissolvable layer dissolves to reveal the figurine's appearance that had been hidden underneath the dissolvable layer. When the toy figurine packaging is coated, the toy figurine packaging hides the identity of a toy figurine enclosed therein until fluid is introduced to the packaging.
