Claims5
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.
