One-piece drink-through cup lid with a straw section

Abstract

A one-piece drink-through cup lid with a straw section includes a conic section and a detachable tube section. The conic section is axially protruding at a center of the cup lid and forming a rim at a top surface of the conic section. The detachable tube section is axially protruding from the rim of the conic section with a closed surface at a top thereof and an annular tear line at a bottom periphery thereof. The conic section and the tube section are formed in one-piece to ensure the cup lid is fully closed and sealed for practical use, and when the tube section is removed by manually tearing along the tear line, a through hole is formed at a top of the conic section so as to form a conic straw section for easily consuming the drink.

What is claimed is:

 a cup lid having defining a peripheral surface and a peripheral edge extending from an outer edge of said peripheral surface, wherein a conic section being formed and protruding to protrude axially at a center of the peripheral surface of said cup lid, said conic section defining and has a bottom periphery connecting to the peripheral surface of said cup lid so as to form a first through hole inside the conic section, and a rim formed by the conic section extending outwardly from the bottom periphery, said conic section flaring radially outward from the rim to the peripheral surface of the cup lid; and   a detachable tube section defining a conic shape, said tube section extending axially from an inner periphery of said rim, and having a closed surface at a top of said tube section and a tear line surrounding a bottom edge of said tube section for detachment;   wherein a diameter of the bottom periphery of the conic section is 25-50% long the length of a diameter of the cup lid; a diameter of the rim of the conic section is 15-25% long the length of the diameter of the cup lid; a height from the bottom periphery to the rim is 25-40% long the length of the diameter of the cup lid; a diameter of the tube section is 8-16% long the length of the diameter of the cup lid; and a height from the rim to the closed surface of the tube section is 10-20% long the length of the diameter of the cup lid,   wherein the bottom diameter (D 3 ) of the second through hole is greater than 8 mm, and the diameter (D 4 ) of the tear line is greater than the bottom diameter (D 3 ) of the tube section by 1 mm˜3 mm, and   wherein the tube section and the conic section are formed in one-piece to form a closed structure of the drink-through cup lid, and when the tube section is detachable torn along the tear line and detached from the tube section, a second through hole being thereby formed at the inner periphery of the tube conic section, said second through hole connecting through the first through hole to form a conic straw section on the cup lid for drinking through.   
     
     
         2 . The one-piece drink-through cup lid with a straw section as claimed in  claim 1 , wherein the tube section is multiple stepped cones. 
     
     
         3 . The one-piece drink-through cup lid with a straw section as claimed in  claim 1 , wherein the conic section forms concave arc contours symmetric in front, back left and right. 
     
     
         4 . The one-piece drink-through cup lid with a straw section as claimed in  claim 1 , wherein the tear line is a broken line. 
     
     
         5 . The one-piece drink-through cup lid with a straw section as claimed in  claim 1 , wherein the diameter of the cup lid is 100 mm; the diameter of the bottom periphery of the conic section is 25-50 mm; the diameter of the rim is 15-25 mm; the height from the bottom periphery to the rim is 25-40 mm; the diameter of the tube section is 8-16 mm; and the height from the rim to the closed surface of the tube section is 10-20 mm. 
     
     
         6 . A one-piece drink-through cup lid with a straw section used for covering on beverage cups, said drink-through cup lid comprising:
 a cup lid having a peripheral surface and a peripheral edge extending from an outer edge of said peripheral surface, a conic section being formed to protrude axially at a center of the peripheral surface of said cup lid, said conic section defining a bottom periphery connecting to the peripheral surface of said cup lid to form a first through hole inside the conic section, and a rim formed by the conic section extending outwardly from the bottom periphery, said conic section flaring radially outward from the rim to the peripheral surface of the cup lid, the shape of the conic section from the rim to the peripheral surface is a downward concave curve; and   a detachable tube section defining a conic shape, said tube section extending axially from an inner periphery of said rim, the tube section is a cone with a narrow top and a wide bottom, and having a closed surface at a top of said tube section and a tear line surrounding a bottom edge of said tube section for detachment, the tear line being a broken line;   wherein the diameter of the bottom periphery of the conic section is 25-50% the length of a diameter of the cup lid, a diameter of the rim of the conic section is 15-25% the length of the diameter of the cup lid; a height from the bottom periphery to the rim is 25-40% the length of the diameter of the cup lid, a diameter of the tube section is 8-16% the length of the diameter of the cup lid, and a height from the rim to the closed surface of the tube section is 10-20% the length of the diameter of the cup lid,   wherein the bottom diameter (D 3 ) of the second through hole is greater than 8 mm, and the diameter (D 4 ) of the tear line is greater than the bottom diameter (D 3 ) of the tube section by 1 mm˜3 mm, and   wherein the tube section and the conic section are formed in one-piece to form a closed structure of the drink-through cup lid, and the tube section is detachable along the tear line from the tube section, a second through hole being thereby formed at the inner periphery of the conic section, said second through hole connecting through the first through hole to form a conic straw section on the cup lid for drinking through.   
     
     
         7 . The one-piece drink-through cup lid with a straw section as claimed in  claim 6 , wherein the tube section is multiple stepped cones. 
     
     
         8 . The one-piece drink-through cup lid with a straw section as claimed in  claim 6 , wherein the left and right sides of the conic section present a symmetrical concave arc curve from top to bottom, first outward and then inward. 
     
     
         9 . The one-piece drink-through cup lid with a straw section as claimed in  claim 6 , wherein the tear line is a broken line.
