Abstract
Abstract A mirror made of a synthetic plastics material in the shape of a shallow tray having a base 5 which is metallised on its internal or external surface at 12 or 13. The shallow tray has rim 6, 7, 9 integral with the periphery of the base. The shape of the cross-section of the rim enables the peripheral edge at the front of the mirror to be convexly rounded at 8 to a required radius greater than the thickness of the base 5. The rim section also serves to hold the base 5 from distortion and so maintains the optical properties of the mirror.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
94 words
A mirror made of a synthetic plastics material characterised in that the mirror is in the shape of a shallow tray or dish having a base (1;5) which is metallised on its internal or external surface, to provide either second or first surface reflection, the shallow tray or dish having a peripheral wall or rim (3;6) upstanding from the base (1;5) and having a height sufficient to permit the peripheral edge (4;8) at the front of the mirror to be convexly rounded to a required radius greater than the thickness of the base (1;5).
Claim 2
Dependent Claim
94 words
A mirror made of a synthetic plastics material characterised in that the mirror is in the shape of a shallow tray or dish having a base (1;5) which is metallised on its internal or external surface, to provide either second or first surface reflection, the shallow tray or dish having a peripheral wall or rim (3;6) upstanding from the base (1;5) and having a height sufficient to permit the peripheral edge (4;8) at the front of the mirror to be convexly rounded to a required radius greater than the thickness of the base (1;5).
Claim 3
Dependent Claim
124 words
A mirror as claimed in Claim 1 having a peripheral rim (6, 7, 9) of substantially the same thickness of plastics material from at least a marginal region (11) of the base (5) of the mirror and throughout the rim, the rim being defined by a first peripherally-inner wall portion (6) thereof extending forwardly, with respect to the mirror from the base (5) thereof, a crest portion (7) curving peripherally outwardly of said first portion (6) to provide at its outer surface (8) said required minimum convex radius of curvature and a second peripherally outer wall portion (9) spaced from said first portion (16) and terminating in substantially the same plane as the rear surface of the base (5) of the mirror. (Figure 6).
Claim 4
Dependent Claim
20 words
A mirror as claimed in Claim 2 in which the substantially uniform thickness of plastics material extends throughout the base.
Claim 5
Dependent Claim
82 words
A mirror as claimed in Claim 2 in which the central portion of the base (5) within said marginal region (11) is made thicker than said marginal region by the provision of a stepped surface (12, 13) extending forwardly from the front face of the central portion of the base within said marginal region thereof, rearwardly from the rear face of said central portion of the base or on both said front and rear faces of said central portion of the base.
Claim 6
Dependent Claim
18 words
A mirror according to any preceding claim which is made to its finished shape by a moulding process.
Claim 7
Dependent Claim
22 words
A mirror according to any preceding claim in which the reflective surface of the base is a metallic layer produced by metallisation.
Claim 8
Dependent Claim
17 words
A mirror according to Claim 6 in which the metallic layer is coated by a protective layer.
