Description
This invention relates to a device for use in removing or tightening screw closures from or on to containers, such as bottles or jars, and is for particular, but not exclusive, use by a person who does not have full hand-gripping power due to, for example, a medical condition, such as arthritis.
In accordance with the present invention, there is provided a device for removing a screw-closure from a container comprising a body having a recess therein shaped to accommodate a screw-closure of a container, the body also having a longitudinal axis, converging wall portions being provided in the recess with an inner surface thereof having a lining of a material having a frictional adherence or resistance property with any screw closure located in contact therewith and having relative rotational movement caused there between by rotation of the container or of the body, the inner surface of the lining being the shape of a bell having an outwardly curving wall, whereby the device can accommodate a maximum range o-E screw-closure sizes within a limited distance along the vertical axis.
Preferably, the body is for manual manipulation. The shape of the body may be a company or discus. The recess is of shape substantially complementary to a frost-conical or bell shape with the recess tapering inwardly.
Preferably also, a bracket is provided to enable the body to be wall or shelf-mounted, two cheeks of the bracket being similarly aperture and the body having a bore whose axis is alienable with those of the apertures to enable a pin to be locatable there through to readily secure the body to the bracket. The bore in the body has its axis at right angles to the axis of the body.
Embodiments of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which:-Fig. 1 shows a vertical cross-section along the rotational axis of a device according to a first I
embodiment of the present invention for use on removing screw closures for containers, the device being shown in a wall-mounted attitude and the upper portion of a ' container being shown in broken line with its screw-closure located in the device;
