First Claim
Patent Images
1. An apparatus for tightening and loosening a cap on a container, comprising:
- a support;
a first rotary member mounted rotatably on said support and rotatable about a first rotation axis;
a complementary unit that is mounted on said support and that is complementary to and that cooperates with said first rotary member to define a cap passage therebetween, said cap passage having a width that is adapted to be configured so as to be slightly smaller than the diameter of the cap in order to permit frictional and sliding contact between said first rotary member and the cap and between said complementary unit and the cap; and
a driving unit for driving said first rotary member to rotate about said first rotation axis;
wherein at least one of said first rotary member and said complementary unit is pivotable relative to said support in such a manner so as to permit widening of said cap passage when the cap is pushed through said cap passage by an external force.
