Device and method for unscrewing a lid from a container body

A device for at least partially unscrewing a lid from a container body, the device comprising:

• a lid engagement portion having opposite first and second ends and having at least one flexible section or mutually articulated sections with at least one lid engagement surface between said first and second ends extending around a first free space for engaging the circumferential surface portion of the lid from opposite sides of the lid;
• a container body engagement portion having opposite first and second ends and having at least one flexible section or mutually articulated sections with at least one container body engagement surface between said first and second ends extending around a second free space for engaging the circumferential surface portion of the container body from opposite sides of the container body;
• a first lever projecting from the first end of the lid engagement portion;
• a second lever projecting from the first end of the container body engagement portion;
• and
• an elastically expandable member connected to extend between the second end of the lid engagement portion and the second end of the container body engagement portion;
• wherein said lid engagement portion, said container body engagement portion, said levers and said elastically expandable member are arranged such that, if said lid engagement surface is in contact with the circumferential surface portion of the lid and if said container body engagement surface is in contact with the circumferential surface portion of the container body, moving the levers towards each other causes said lid engagement surface to entrain the circumferential surface portion of the lid relative to the container body engagement portion, said container body engagement surface to entrain the circumferential surface portion of the container body relative to the lid engagement portion and said elastically expandable member to be elongated.
