ABSTRACT:
FIELD OF INVENTION
This invention relates to a foil cutter and such a cutter in combination with a crown top opener and/or a corkscrew.
BACKGROUND OF INVENTION
A foil cutter is known, for example from EP-A-0220850, having four rotatable cutters mounted in a flexible U-shaped frame. The foil cutter is completely separate from any other bottle opening apparatus such as a self-pull extractor, for example as disclosed in EP-A-0129301.
SUMMARY OF THE INVENTION
In one aspect this invention provides a foil cutter comprising an annular casing having a passage extending axially therethrough and adapted to accommodate the neck of a wine bottle, and a pair of cutting members having cutting edges mounted in the casing so that each extends or is movable to extend into the passage in a plane normal to the axis, one or more of the cutting edges or a guide member aligned therewith being movable relative to the casing radially inwardly of the passage so as to ensure that both cutting edges engage a bottle neck located in said passage. Preferably the passage is substantially circular sectioned and each movable member is biased outwardly of the casing and is attached to a push member extending to the outside of the casing for pressing the movable member radially inwardly. The or each movable member may for example be movable to give a variation of diameter of the cutting circle including the cutting/guide edges in the range 3 to 5 mm.
In one form the cutting members in the form of wheels are mounted radially opposite one another with one fixed relative to the casing and the other movable radially inwardly. In another form each of the opposite cutting wheels is movable radially. In another form the cutting wheels and a guide member are substantially equally angularly spaced from one another and the cutting wheels are radially fixed with the guide member movable radially inwardly. Further configurations of cutting/guide wheels are clearly possible.
In the preferred form the casing forms a substantially closed outer shell apart from the opening(s) for the push member or members. In a preferred form one of the openings to the passage is shaped to define a crown cap opener or a separate crown cap opener is attached in a recess of the foil cutter. This may for example take the form of the opening being defined by a flat edge. In this form the device has a dual use as a foil cutter and crown top opener. In an alternative a foil cutter may be separate from a crown top opener but the foil cutter and crown top opener are arranged to be a retaining fit together, for example a push fit.
Preferably the base of the foil cutter or crown top opener is flat so that the casing is stable when supported on a flat surface. In another aspect the invention comprises a foil cutter or combined foil cutter and crown top opener which is arranged to form a stand for a corkscrew, the corkscrew being arranged to be a comfortable push fit in the passage of the foil cutter so that the corkscrew will be supported by and stand up from the foil cutter supported on a support surface.
