Abstract
Abstract A toy flip cap adapted to be sailed through the air by means of placing the cap between the thumb and the middle finger and then snapping the fingers, the cap thus being flipped outwardly to travel along various flight paths. The flip cap comprises an annular body defined by a substantially flat top wall having a flared peripheral depending wall. The peripheral wall is the portion of the cap that is held between the thumb and the middle finger, and it is designed to provide an aerodynamic lift by the force resulting from the snapping of the fingers.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
117 words
A flip-top toy comprising: a circular body member formed having an approximate diameter between three-quarters of an inch to one and one-half inch; wherein said circular body includes a substantially flat top wall having an annular flange wall extending radially downward and outward from said flat top wall; said flange having a curvilinear cross-sectional configuration defined by an outer concave surface and an inner convex surface, whereby said surfaces are tapered inwardly of each other as said flange wall extends radially outward; said tapered surfaces being adapted to be positioned between an individual's thumb and middle finger, whereby the snapping of said thumb and middle finger results in an aerodynamic flight of said top through the air.
Claim 2
Dependent Claim
117 words
A flip-top toy comprising: a circular body member formed having an approximate diameter between three-quarters of an inch to one and one-half inch; wherein said circular body includes a substantially flat top wall having an annular flange wall extending radially downward and outward from said flat top wall; said flange having a curvilinear cross-sectional configuration defined by an outer concave surface and an inner convex surface, whereby said surfaces are tapered inwardly of each other as said flange wall extends radially outward; said tapered surfaces being adapted to be positioned between an individual's thumb and middle finger, whereby the snapping of said thumb and middle finger results in an aerodynamic flight of said top through the air.
Claim 3
Dependent Claim
14 words
A flip-top toy as recited in claim 1, wherein said top wall is concaved.
Claim 4
Dependent Claim
14 words
