Hollow body having a wall with a layer of glass and at least one elevated region

A process for making an item, comprising as process steps:

• a) providing a hollow body comprising a wall which at least partially surrounds an interior volume of the hollow body, the wall comprising a layer of glass comprising a first glass composition, the wall comprising an interior surface that faces the interior volume and an exterior surface opposite the interior surface that faces away from the interior volume, the wall defining a plurality of exterior diameters, the wall defining a maximum exterior diameter in at least one contact region, the maximum exterior diameter extending along at least a portion of a height of the hollow body;
• b) contacting the exterior surface of the wall in the at least one contact region with a composition comprising a plurality of particles, the particles of the plurality of particles comprising a further glass composition;
• and
• c) forming a plurality of elevated regions each comprising the further glass composition on the exterior surface of the wall in the at least one contact region from the composition and joining the plurality of elevated regions to the exterior surface in the at least one contact region, wherein the plurality of elevated regions covers 5% to 90% of the at least one contact region and comprises spaced apart elevated regions each extending from the exterior surface of the wall in the at least one contact region.

A process, comprising:

• using a plurality of a plurality of glass particles for functionalizing an exterior surface of a wall of a glass container for packaging a pharmaceutical composition, the glass container comprising the wall which at least partially surrounds an interior volume of the hollow body, the wall comprising a layer of glass comprising a first glass composition, the wall comprising an interior surface that faces the interior volume and the exterior surface opposite the interior surface that faces away from the interior volume, the wall defining a plurality of exterior diameters, the wall defining a maximum exterior diameter in at least one contact region, the maximum exterior diameter extending along at least a portion of a height of the hollow body, the functionalizing comprising:
• A} contacting the exterior surface in the at least one contact region with the plurality of glass particles;
• and
• B} forming a plurality of elevated regions each comprising a further glass composition at least in part from the plurality of glass particles and joining the plurality of elevated regions to the exterior surface in the at least one contact region, wherein the plurality of elevated regions covers 5% to 90% of the at least one contact region and comprises spaced apart elevated regions each extending from the exterior surface of the wall in the at least one contact region.

A process, comprising as process steps:

• A) providing a hollow body comprising:
• a wall which at least partially surrounds an interior volume of the hollow body, the wall comprising a layer of glass comprising a first glass composition, the wall comprising an interior surface that faces the interior volume and an exterior surface opposite the interior surface that faces away from the interior volume, the wall defining a plurality of exterior diameters, the wall defining a maximum exterior diameter in at least one contact region, the maximum exterior diameter extending along at least a portion of a height of the hollow body, wherein at least one elevated region extends from the exterior surface of the wall in the at least one contact region and comprises a further glass composition, wherein the at least one elevated region covers 5% to 90% of the at least one contact region, wherein the at least one elevated region comprises a plurality of spaced apart elevated regions each extending from the exterior surface of the wall in the at least one contact region;
• B) inserting a pharmaceutical composition into the interior volume;
• and
• C) closing the hollow body.
