Abstract
A cup-shaped container formed of a molded synthetic resin. 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.
Claims25
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 connector means with a variable connection force, said connector 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;
- and
- means operatively associated with a closure for said container and with said handle for increasing the connection force selectively independently of the presence of liquid in the container.

A selectively closable drinking cup comprising:
- a molded cup-shaped container having a sidewall portion defining an upper circumferential edge portion, and provided with integral connection means configured to permit removal of the molded container from a 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.

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.
