A handle is removably secured to a connector portion of the container, with the connection therebetween being constructed to cause an increase in the connection force as a result of weight of liquid placed in the container when the handle is supported as by a person using the container as a drinking cup. In one embodiment, the invention utilizes a closure having frictional engagement with an upper edge portion of the container for selectively closing the same. A connector between the closure and the handle provides an increase in the connection force as a result of the closure being secured to the container edge portion. ## Claims ### Claim 1 A drinking cup comprising: a molded cup-shaped container having a sidewall portion provided with integral connector means configured to permit removal of the molded container from a maintained rigid mold in which it is molded;

a handle having an integral connector portion configured to be removably connected to said connection means with a variable connection force, said connection means and connector portion being constructed to cause an increase in the connection force as a result of weight of liquid placed in the container with the handle being supported as by a person drinking the liquid from the cup; a closure for frictional engagement with said edge portion for selectively closing the cup; and connecting means connecting the closure to the handle and defining means for causing an increase in the connection force as a result of the closure being secured to said edge portion. ### Claim 17 (depends on 16) The drinking cup of claim 16 wherein said connecting means comprises means defining a resilient connection of the closure to the handle. ### Claim 18 (depends on 16) The drinking cup of claim 16 wherein said handle defines an upper portion and said connecting means comprises means defining a resilient connection of the closure to said upper portion of the handle. ### Claim 19 (depends on 16) The drinking cup of claim 16 wherein said connecting means comprises means defining a resilient connection of the closure to the handle causing the closure to extend perpendicularly to a plane defining the upper distal surface of said upper circumferential edge portion of the container. ### Claim 20 (depends on 16) The drinking cup of claim 16 wherein said connecting means comprises means defining a resilient connection of the closure to the handle causing the closure to extend perpendicularly to a plane defining the upper distal surface of said upper circumferential edge portion of the container, said connecting means comprising a twistable and bendable means formed of synthetic resin. ### Claim 21 A selectively closable drinking cup comprising: a molded cup-shaped container having a sidewall portion defining an upper circumferential edge portion and integral connection means on the sidewall portion; a handle having an integral connector portion configured to be removably connected to said connection means; a closure for selectively closing the container by extension thereof across the container at said upper edge portion; and connecting means unitarily connecting the closure to the handle, said closure being disposed in any one of a plurality of different positions relative to the container when the handle is retained in fixed association with the container, said handle, closure, and connecting means being unitarily molded of synthetic resin to define a one-piece structure. ### Claim 22 (depends on 21) The drinking cup of claim 21 wherein said connecting means comprises a flexible strap. ### Claim 23 A selectively closable drinking cup comprising: a molded cup-shaped container having a sidewall portion defining upper circumferential edge portion and integral connection means on the sidewall portion; a handle having an integral connector portion configured to be removably connected to said connection means; a closure for selectively closing the container by extension thereof across the container at said upper edge portion; and connecting means unitarily connecting the closure to the handle, said handle, closure, and connecting means being unitarily molded of synthetic resin to define a one-piece structure, said connecting means being connected to an upper portion of the handle. ### Claim 24 A selectively closable drinking cup comprising: a molded cup-shaped container having a sidewall portion defining upper circumferential edge portion and integral connection means on the sidewall portion;
