Abstract
A can opener (1) for opening a can (2) comprises a rotating device (4), a body (5), a traction device (6), a removal device (8) comprising at least one engagement element (9), and a cutting device (7). The traction device (6) is configured to adapt at least a traction device cutting position (tc) and a traction device lifting position (tl). The traction device (6) in the traction device cutting position (tc) and the cutting device (7) are arranged so as to open a can (2). The traction device (6) in the traction device lifting position (tl) and the engagement element (9) in a removal device lifting position (rl) are arranged such as to engage a lid (3) of an opened can (2). An actuation of the removal device (8) t removes an engagement between the traction device (6) and the engagement element (9) with the lid (3).
Claims17
A can opener for opening a can comprising:
- a rotating device,
- a body,
- a traction device, and
- a cutting device,
- wherein the rotating device is rotatably arranged on the body and is configured to rotate about a rotation axis along a first rotation direction and along a second rotation direction running opposite to the first rotation direction,
- wherein the traction device is arranged on the body and is configured to adapt at least a traction device cutting position upon rotation of the rotating device along the first rotation direction and to adapt a traction device lifting position upon rotation of the rotating device along the second rotation direction,
- wherein the traction device in the traction device cutting position and the cutting device are arranged so as to open a can,
- wherein the can opener further comprises a removal device comprising at least one engagement element,
- wherein the traction device in the traction device lifting position and the engagement element in a removal device lifting position are arranged such as to engage a lid of an opened can, and
- wherein the can opener is further configured such that an actuation of the removal device transfers the traction device into a traction device release position and the removal device into a removal device release position, whereby an engagement between the traction device and the engagement element with the lid is removed.
A method of producing a can opener, the method comprising the steps of:
- providing a rotating device,
- providing a body,
- providing a traction device, and
- providing a cutting device,
- wherein the rotating device is rotatably arranged on the body and is configured to rotate about a rotation axis along a first rotation direction and along a second rotation direction running opposite to the first rotation direction,
- wherein the traction device is arranged on the body and is configured to adapt at least a traction device cutting position upon rotation of the rotating device along the first rotation direction and to adapt a traction device lifting position upon rotation of the rotating device along the second rotation direction,
- wherein the traction device in the traction device cutting position and the cutting device are arranged so as to open a can,
- wherein the method further comprises the step of
- providing a removal device comprising at least one engagement element,
- wherein the traction device in the traction device lifting position and the engagement element in a removal device lifting position are arranged such as to engage a lid of an opened can, and
- wherein the can opener is further configured such that an actuation of the removal device transfers the traction device into a traction device release position and the removal device into a removal device release position, whereby an engagement between the traction device and the engagement element with the lid is removed.
