The spline 113 is a continuous negative space that is formed in the interiors of both the tapered prism structure 111 and the extension structure 112. The spline 113 is defined elsewhere in this disclosure. The spline 113 is a non-Euclidean prism structure. The spline 113 forms a non-Euclidean tubular structure that stores the toothpaste 115 within the brush structure 101. The spline 113 transports the toothpaste 115 to the brush head 141 of the extension structure 112. The spline 113 discharges the toothpaste 115 into the brush head 141.
