Glass container with embossed indicia
A glassforming blank mold having an internal surface and an engraving in the internal surface, wherein the engraving, in cross section, includes a radially outward surface having a circumferential width, and sidewalls connecting the radially outward surface to the internal surface of the blank mold, and including fillets between the radially outward surface and the sidewalk, and rounds between the sidewalls and the internal surface of the blank mold, such that the sidewalls are not straight but, instead, are continuously curving. A method of making a glass container using the mold is also disclosed, as is the glass container itself.
1. A glassforming blank mold having an internal surface and an engraving in the internal surface, wherein the engraving, in cross section, includes:
a radially outward surface, and
sidewalls connecting the radially outward surface to the internal surface of the blank mold and including fillets and rounds between the radially outward surface and the internal surface of the blank mold, such that the sidewalls are not straight but, instead, are continuously curving,
wherein a circumferential width of the radially outward surface is at least 1.0 mm, a radial thickness between the internal surface and the radially outward surface is 0.2 mm to 0.4 mm, the fillets have radii between 0.2 mm and 0.4 mm, the rounds have radii between 1.25 mm and 1.75 mm such that a ratio of radii of the rounds to an engraving radial depth is between 3:1 and 9:1, and a circumferential overall width of the engraving is at least 1.8 mm.
2. The mold set forth in claim 1 , wherein each of the fillets extends over an angle of less than 90°.
3. The mold set forth in claim 1 , wherein the sidewalls are characterized by an inflection between the fillets and the rounds.
4. The mold set forth in claim 1 wherein a ratio of radii of the fillets to an engraving radial depth is between 0.5:1 and 2:1.
5. The mold set forth in claim 1 wherein a ratio of a container wall thickness to an engraving radial depth is between 3:1 and 15:1.
6. A method of making a glass container having a base, a body extending axially from the base, and a generally radially outwardly facing external surface, the method including the steps of:
(a) providing the glassforming blank mold of claim 1 ;
(b) forming a parison into conformity with the internal surface of a blank mold including the engraving in the internal surface to form an embossment on an exterior surface of the parison; and
(c) blowing the parison into conformity with an internal surface of a blow mold to produce a container from the parison, including pushing the embossment against the blow mold internal surface into a wall of the container so as to push corresponding material through the wall of the container into an interior of the container.
7. The method set forth in claim 6 wherein the providing step (a) includes the engraving being located in at least one of a neck portion or a body portion of the blank mold such that the embossment is formed on at least one of a neck portion or a body portion of the parison.
8. A glassforming blank mold having an internal surface and an engraving in the internal surface, wherein the engraving, in cross section, includes:
a radially outward surface and sidewalls connecting the radially outward surface to the internal surface of the blank mold, wherein the sidewalls comprise fillets and rounds, such that the sidewalls are not straight but, instead, are continuously curving,
wherein the rounds have radii between 1.25 mm and 1.75 mm such that a ratio of radii of the rounds to a radial depth of the engraving is between 3:1 and 9:1.
9. The mold set forth in claim 8 , wherein a ratio of radii of the fillets to the radial depth of the engraving is between 0.5:1 and 2:1.
10. The mold set forth in claim 8 wherein a ratio of a container wall thickness to the radial depth of the engraving is between 3:1 and 15:1.
11. The mold set forth in claim 8 wherein a circumferential width of the radially outward surface is at least 1.0 mm, a radial thickness between the internal surface and the radially outward surface is 0.2 mm to 0.4 mm, the fillets have radii between 0.2 mm and 0.4 mm, and a circumferential overall width of the engraving is at least 1.8 mm.
12. A method of making a glass container having a base, a body extending axially from the base, and a generally radially outwardly facing external surface, the method including the steps of:
(a) providing the glassforming blank mold of claim 8 ;
(b) forming a parison into conformity with the internal surface of a blank mold including the engraving in the internal surface to form an embossment on an exterior surface of the parison; and
(c) blowing the parison into conformity with an internal surface of a blow mold to produce a container from the parison, including pushing the embossment against the blow mold internal surface into a wall of the container so as to push corresponding material through the wall of the container into an interior of the container.
13. The method set forth in claim 12 , wherein the providing step (a) includes the engraving being located in at least one of a neck portion or a body portion of the blank mold such that the embossment is formed on at least one of a neck portion or a body portion of the parison.
