Abstract:
1. A magnifier device for mounting to a container, comprising: a container mount comprising a base portion and an adjustable portion, each of the base portion and the adjustable portion comprising a container engaging surface, the container engaging surfaces being arranged for engaging a container received therebetween; the adjustable portion being mounted for movement relative to the base portion in (i) a contracting direction wherein the container engaging surfaces move relatively towards one another and (ii) an expanding direction wherein the container engaging surfaces move relatively away from one another, thus enabling receipt of containers of various sizes between the container engaging surfaces, the expanding and contracting directions corresponding to a diameter of the container; the container mount comprising a resilient member for biasing the adjustable portion in the contracting direction, thus urging engagement of the container engaging surfaces against a container received therebetween; a magnifying lens secured to a lens mounting part of the base portion of the container mount, wherein the lens mounting part is fixed with respect to the container engaging surface of the base portion and fixedly determines a spacing between an external vertical surface of the container and the lens oriented in a vertical direction substantially perpendicularly to the expanding and contracting directions to establish an essentially fixed distance between the lens and the external vertical surface of the container; a hinge pivotally mounting the magnifying lens to the lens mounting part solely for pivotal movement about a pivot axis between a use position oriented in the vertical direction substantially perpendicularly to the expanding and contracting directions and a storage position, wherein the hinge restricts the movement of the magnifying lens between the use and storage positions to said pivotal movement about said pivot axis; a container engaging element spaced from the pivotal mounting of the magnifying lens by the hinge and movable with the magnifying lens, the container engaging element having a container engaging surface positioned and configured to engage the container when the magnifier device is mounted to the container and the lens is pivoted about said pivot axis to the use position such that the container engaging element cooperates with the lens mounting part to fixedly determine the spacing between the lens oriented in the vertical direction to establish the essentially fixed distance between the lens and the external vertical surface of the container.
