Abstract
A method for forming a fritted cover sheet includes providing a substrate and depositing an initial frit bead on the substrate. Thereafter, at least one additional frit bead is deposited on the substrate such that a base of the at least one additional frit bead contacts a base of an adjacent frit bead thereby forming a frit seal on the substrate.
Claims14
A method for forming a fritted cover sheet comprising:
- providing a glass substrate;
- depositing an initial frit bead on the substrate to form a contiguous circuit defining a perimeter around a sealing area on the substrate;
- and
- depositing at least one additional frit bead on the substrate along the contiguous circuit and adjacent to a previously deposited frit bead such that a base of the at least one additional frit bead overlaps a base of the respective adjacent frit bead thereby forming a frit seal on the substrate;
- wherein the initial frit bead and the at least one additional frit bead have sidewalls which taper from the base towards a top surface of the respective frit bead.

A method for forming a glass package comprising:
- providing a first glass substrate and a glass second substrate;
- depositing an initial frit bead on the first substrate to form a contiguous circuit defining a perimeter around a sealing area on the first substrate;
- depositing a second frit bead on the first substrate along the contiguous circuit and adjacent to the initial frit bead such that a base of the second frit bead overlaps a base of the initial frit bead to form a frame-like frit seal on the first substrate;
- wherein the initial frit bead and the second frit bead have sidewalls which taper from the base towards a top surface of the respective frit bead;
- positioning the first substrate on the second substrate such that the frit seal is disposed between the first substrate and the second substrate;
- and heating the frit seal to form a seal between the first substrate and the second substrate.
