Abstract

A glass article including a frame having a frame support surface, a glass sheet having a first major surface and a second major surface in which the second major surface is opposite to the first major surface, and an adhesive bead disposed between the frame support surface and the second major surface. The adhesive bead defines a bead path. The adhesive bead has a cross-section perpendicular to the bead path, and the cross-section includes a width and a height. The height is a maximum dimension perpendicular to the second major surface of the glass sheet, and the width is a maximum dimension parallel to the second major surface of the glass sheet. An aspect ratio of the height to the width is at least 0.6, and the width is 2 mm or less.

First claim

What is claimed is:

1. A glass article, comprising:
a frame comprising a frame support surface;
a glass sheet comprising a first major surface and a second major surface, the second major surface being opposite to the first major surface;
an adhesive bead disposed between the frame support surface and the second major surface, the adhesive bead defining a bead path;
wherein the adhesive bead has a cross-section perpendicular to the bead path, the cross-section comprising a width and a height;
wherein the height is a maximum dimension perpendicular to the second major surface of the glass sheet and the width is a maximum dimension parallel to the second major surface of the glass sheet;
wherein an aspect ratio of the height to the width is at least 0.6 and at most 1.2; and
wherein the width is 2 mm or less.

2. The glass article of claim 1 , wherein the width is at least 0.5 mm and wherein the height is from 0.5 mm to 2 mm.

3. The glass article of claim 1 , wherein a cross-sectional area of the adhesive bead perpendicular to the bead path defines one of a bulging rectangle, a rectangle, and an hourglass.

4. The glass article of claim 1 , wherein the bead path is continuous between the frame support surface and the second major surface.

5. The glass article of claim 1 , wherein the bead path is discontinuous between the frame support surface and the second major surface.
