1. A pair of dispensers comprising:
a. a first dispenser comprising:
i. a container having an arc-like shape, and having a front face, a back face, a top face, a bottom face, a left face, a right face, and at least one cavity;
1. the front face of said container being a substantially planar arc-shaped surface having a top edge, an opposing bottom edge, a left edge and an opposing right edge;
a. the top edge of said front face being a concave circular arc of constant radius of curvature;b. the opposing bottom edge of said front face being a convex circular arc of constant radius of curvature equal to the radius of curvature of the top edge thereof, being approximately concentric with the top edge thereof, and being substantially longer than the top edge thereof;c. the left edge of said front face being a straight line which intersects a tangent to the arc of the top edge thereof, said tangent being determined at the left end point of the top edge of said front face, at an angle greater than 100,° and which intersects a tangent to arc of the bottom edge thereof, said tangent being determined at the left end point of the bottom edge of said front face, at an angle less than 86°; and,d. the opposing right edge of said front face being a straight line which intersects a tangent to the arc of the top edge thereof, said tangent being determined at the right end point of the top edge of said front face, at an angle greater than 85,° and intersects a tangent to the arc of the bottom edge thereof, said tangent being determined at the right end point of the bottom edge of said front face, at an angle less than 101°;2. the back face of said container being a substantially planar arc-shaped surface having a top edge, an opposing bottom edge, a left edge and an opposing right edge;
a. the back face of said container being a mirror image of, and substantially parallel to, the front face thereof;b. the left edge of the back face of said container being substantially parallel to the opposing right edge of the front face thereof; and,c. the opposing right edge of the back face of said container being substantially parallel to the left edge of the front face thereof;3. the top face of said container being a cylindrically curved concave surface of constant radius of curvature equal to the radius of curvature of the top edge of the front face thereof, and extending substantially perpendicularly between the top edge of the front face thereof and the top edge of the back face thereof;4. the bottom face of said container being a cylindrically curved convex surface of the same constant radius of curvature as the bottom edge of the front face thereof, and extending substantially perpendicularly between the bottom edge of the front face thereof and the bottom edge of the back face thereof;5. the left face of said container being a substantially planar surface, being substantially rectangular in shape, and extending substantially perpendicularly between the left edge of the front face thereof and the opposing right edge of the back face thereof;6. the right face of said container being a substantially planar surface, being substantially rectangular in shape, and extending substantially perpendicularly between the opposing right edge of the front face thereof and the left edge of the back face thereof; and,7. the at least one cavity of said container opening onto at least one face thereof, and being of sufficient size and shape to receive and store a predetermined substance or substances or items;ii. a means for dispensing the substance or substances or items contained within the at least one cavity of said container; and,iii. optionally, a means for sealing the substance or substances or items stored within the at least one cavity of said container; and, b. a second dispenser comprising:
i. a container having an arc-like shape, and having a front face, a back face, a top face, a bottom face, a left face, a right face, and at least one cavity;
1. said container being congruent with the container of the first dispenser; and,2. the at least one cavity of said container opening onto at least one face thereof, and being of sufficient size and shape to receive and store a predetermined substance or substances or items;ii. a means for dispensing the substance or substances or items stored within the at least one cavity of said container; and,iii. optionally, a means for sealing the substance or substances or items stored within the at least one cavity of said container;whereby, upon positioning the two dispensers such that the whole of the concave top face of the container of the first dispenser is contiguous with the convex bottom face of the container of the second dispenser, and, additionally, the left face of the container of the first dispenser is aligned with and substantially coplanar with the left face of the container of the second dispenser, the pair of dispensers present an optical illusion, namely that the second dispenser appears to be substantially larger than the first dispenser. |
