as shown in fig1 a , a typical disposable paper cup 10 has an open larger diameter conical end 12 for content pouring and consuming , and a closed smaller diameter conical end 14 . a typical insulator sleeve 20 , as shown in fig1 b , has an open larger diameter conical end 22 and an open smaller diameter conical end 24 . fig1 c shows the typical usage of the insulator sleeve 20 over the paper cup 10 . as shown in fig2 a - 2 c , a conventional insulating cup holder 30 is typically formed from a paperboard blank 32 , having a first end 34 and a second end 36 , together with an arcuate top edge 38 and an arcuate bottom edge 40 . the paperboard can have a smooth surface 42 and a corrugated surface 44 , two smooth surfaces or two corrugated surfaces . when the ends 34 , 36 have been adhered together , the blank may be folded for storage and shipping ; see fig2 b and 2 c . conversely , when the blank is formed into an assembled configuration , the holder forms a tapered sleeve that may be positioned about a tapered container ; see fig1 b and 1 c . the ring 50 is adapted to slip - fit onto one of the conical ends 22 , 24 of the sleeve . for example , the ring is fitted on the smaller diameter conical end 24 of the insulator sleeve 20 as shown in an enlarged perspective view in fig3 . this rim , band , circlet or ring 50 is preferably made of a pliable plastic rubber material that is in the shape of a circle from a perpendicular view , and the shape of a “ u ” from a cross - sectional view . the ring 50 is preferably 2½ to 3¼ in diameter 52 and ½ to 1½ tall on the outside perimeter 54 . accordingly , the ring 50 is dimensioned so as to be fitted around the end of a standard sized insulating sleeve , but can be customarily sized as necessary . the outside perimeter 54 can be adaptable to receive print and / or the ability to receive so - called dry erase markings . referring to fig4 in conjunction with fig3 , the “ u ” shape 56 is formed where the outer wall 58 and the inner wall 60 meet at the leading edge 62 of the ring 50 . it is the channel 64 between the walls that receives the smaller diameter conical end 24 of the insulator sleeve 20 . the inside surface 66 of the outer wall 58 includes a plurality of protrusions 68 for retaining the sleeve 20 within the channel 64 of the ring 50 . the outside surface 70 of the inside wall 60 can be tapered towards the center 72 of the ring 50 away from the leading edge 62 . it is the size of the inner wall and / or the taper that will aid in the airfoil characteristics of the toy by minimizing any wind resistance issues that may be caused by a corrugated inside surface of the insulator sleeve 20 . while an embodiment describing a “ u ” shaped circlet has been shown and described , it will be appreciated that other forms of a weighted leading edge ringlet are envisioned . for example , other means of coupling the weighted ring to the leading edge of the sleeve can be used . such coupling can be to the inside surface of the sleeve , the outside surface , or both . so long as the ring is adapted to receive a conical end the insulator sleeve to improve the flying characteristics of the sleeve / ring aerial toy combination . as shown in fig5 and 6 , the aerial toy 80 is formed when the insulator sleeve 20 is coupled to the ring 50 . the toy 80 is picked up like a can and thrown like a football with the weighted ring end forward and spiraling , the thin walled sleeve 20 provides the lift and the directional stability of the toy 80 , while the stronger ring 50 provides the structural strength and improves the flying characteristics of the toy 80 . air flow is improved by the high and / or tapered inside wall 60 and ensures a uniform flight regardless of any corrugated surfaces of the sleeve 20 . the foregoing detailed description has been given for clearness of understanding only and no unnecessary limitations should be understood therefrom . accordingly , while one or more particular embodiments of the disclosure have been shown and described , it will be apparent to those skilled in the art that changes and modifications may be made therein without departing from the disclosure if its broader aspects , and , therefore , the aim in the appended claims is to cover ail such changes and modifications as fall within the true spirit and scope of the present disclosure .
an aerial toy is formed by coupling a ring to an insulating sleeve used with disposable paper cups . the ring is attached to the smaller diameter conical end of the insulator sleeve creating a flying gyroscope . the flight of the toy is protracted due to the airfoil characteristics of the tubular body and is thrown like a football for distance , accuracy , fun and competition .
