Definitions

• the present specification generally relates to methods and apparatuses for packaging glass articles and, more particularly, to methods and apparatuses for packaging glass articles, such as tubes for pharmaceutical packages that reduce or even eliminate glass-to-glass interactions during the packaging process.
• glass has been used as the preferred material for packaging pharmaceuticals because of its hermeticity, optical clarity, and excellent chemical durability relative to other materials. Specifically, the glass used in pharmaceutical packaging must have adequate chemical durability so as not to affect the stability of the pharmaceutical compositions contained therein. Glasses having suitable chemical durability include those glass compositions within the ASTM standard 'Type IB' which have a proven history of chemical durability.
• This mechanical damage can significantly decrease the strength of the glass pharmaceutical package resulting in an increased likelihood that cracks will develop in the glass, potentially compromising the sterility of the pharmaceutical contained in the package or causing the complete failure of the package. Reducing or even eliminating glass-to-glass contact can result in significant improvements in physical properties of the pharmaceutical packages.

• the glass article layer 40 may be moved along the conveying areas 162, 164 and 166 to a bundle building station 172.
• the robotic lift assembly 152 may be used to lift the glass article layer 40 and stack the glass article layers 40, one on top of another to form a bundle 174 within a shipping container 176, as opposed to wrapping as described above.
• the bundle may both wrapped and placed in the shipping container 176.
• the shipping container 176 may be wrapped in a plastic film.
• the bundle 174 may be transported to a palletized package building station.
• a pusher 178 of the conveying system 124 may be used to push the bundle 174 along with the shipping container 176 out of the bundle building station 172.
• FIG. 13 once the bundle 174 is removed, another empty shipping container 180 may be delivered to the bundle building station 172.
• FIG. 14 illustrates the shipping container 180 ready to be filled with glass article layers 40 including the layer separation inserts 42, 44 and 46.
• an individual layer separation insert 190 may be used to support multiple glass articles.
• the layer separation insert 190 may include article receiving slots 192 that are sized to receive the glass articles therein. Side walls 194 may be provided that separate the article receiving slots 192 in a fashion similar to that described above.
• the layer separation inserts 190 may be nestable. Rotated 180 degrees, the layer separation inserts 190 may only be stackable and not nestable.
• FIG. 16 illustrates a layer separation insert 190 with a glass article 198.
• the above-described apparatuses and methods can be used to handle and package relatively large numbers of glass articles, while minimizing or even eliminating glass-to-glass contact or human contact with the glass articles. Such an arrangement can reduce potential glass article fracture sites (scratches, defects, chips, etc.), which can, in turn, improve strength of the glass articles and improve cleanliness.
• the apparatuses and methods may be used with or without shipping containers, such as boxes by wrapping the glass articles in a plastic film.
