Patent ID: 7040194

Claim:
An opener for a container having a screw or twist off closure comprising: a housing, a rotational drive shaft having a stationary position, a first rotational guide and a first spring connecting the first guide to the housing, the first spring having a deflected position storing rotational energy when the shaft is in the stationary position, a second rotational guide coaxial with the first guide, a first pair of opposed jaws slidably provided on the first guide, a first coupling device connecting the first jaws to the housing so that rotation of the first guide causes movement of the first jaws along the first guide, a second pair of opposed jaws slidably provided on the second guide, a second coupling device connecting the second jaws to the shaft so that rotation of the shaft causes movement of the second jaws along the second guide, and the shaft being rotatable in a first direction to move the second jaws to engage a closure of a container between the jaws, and thereby rotational energy in the first spring is released to move the first jaws to engage the container.
