| 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.

I 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 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.
