Publication number: 20240140063Abstract: A dunnage conversion system (100) includes a supply area (120), a dunnage conversion machine (110), and an arcuate slot (130). The supply area (120) is configured to hold a supply of a sheet material (122). The sheet material (122) is in a substantially flat configuration in the supply area (120). The dunnage conversion machine (110) is configured to pull the sheet material (122) from the supply area (120) and to convert the sheet material (122) into a non-flat configuration. The arcuate slot (130) is positioned between the supply area (120) and the dunnage conversion machine (110) such that the sheet material (122) is fed through the arcuate slot (130) as the sheet material (122) passes along a path from the supply area (120) to the dunnage conversion machine (110).Type: ApplicationFiled: October 29, 2020Publication date: May 2, 2024Inventors: Christopher C. Hamlin, Thomas P. Orsini, Russell T. Christman

Patent number: 11940651Abstract: A light guide comprising a polymeric layer at least 25 percent transmissive over at least a 30 nm bandwidth in a wavelength range from 180 to 280 nm over a distance of at least 100 micrometers and visible light transparent reflecting layers (UV-C mirror) that are at least 50 percent reflective over at least 30 nm bandwidth in a wavelength range from 180 to 280 nm over an incident light angle of 0 to 90 degrees and that are at least 25 percent transmissive of visible light over at least 30 nm bandwidth in a wavelength range of 400 to 800 nm over an incident light angle of 0 to 90 degrees. The light guide is useful, for example, for antimicrobial surfaces.Type: GrantFiled: December 23, 2019Date of Patent: March 26, 2024Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Timothy J.

Publication number: 20220324192Abstract: A drive system is configured to feed a sheet material. The drive system includes a first roller and a second roller. A circumference of the first roller has a first curved profile. A circumference of the second roller has a second curved profile. The first and second rollers are arranged such that, when the sheet material is not located between the first and second rollers, the first curved profile of the first roller contacts the second curved profile of the second roller. The first and second rollers are further arranged such that, when the sheet material is located between the first and second rollers, rotation of at least one of the first and second rollers causes the sheet material to be fed through the drive system.Type: ApplicationFiled: September 10, 2020Publication date: October 13, 2022Inventors: Christopher C. Hamlin, Thomas P. Orsini, Russell T. Christman

Publication number: 20220297924Abstract: A system for dispensing mailers includes a retention system and a container. The retention system includes a surface and a retention mechanism. A portion of the retention mechanism extends transversely across a front of the surface. The container holds mailers. The container is supported by the surface of the retention system. The container includes a dispensing aperture that permits the mailers to be dispensed through a first panel of the container. The container is located so that a second panel of the container is substantially parallel to the surface. The dispensing aperture is between the surface of the retention system and a portion of the retention mechanism. The retention mechanism deters movement of the container toward the retention mechanism while a first mailer is dispensed from the container.Type: ApplicationFiled: June 12, 2020Publication date: September 22, 2022Inventors: William A. Snyder, Jessica L. Denson, Mark R. Garceau, Christopher C. Hamlin, Patrick G. White, Russell T. Christman, Thomas P. Orsini, Steven E. Maston, Jessica B. Galuardi, Donald Durant

Patent number: 11383456Abstract: A system (300) for closing mailers includes a forming funnel (320) and a fusing device (310). The forming funnel includes funneling surfaces that receive an opening of a mailer in an insertion direction (302) and constrain the opening of the mailer after the opening of the mailer is inserted. The funneling surfaces are arranged to continue constraining the opening of the mailer as the mailer moves in a sliding direction (304). The fusing device includes a slot that receives the constrained opening of the mailer from the forming funnel. The fusing device applies pressure and heat to the opening of the mailer as the opening of the mailer moves through the slot. The pressure and the heat applied by the fusing device cause portions of the opening to fuse together to close the mailer.Type: GrantFiled: April 12, 2019Date of Patent: July 12, 2022Assignee: Sealed Air Corporation (US)Inventors: Christopher C. Hamlin, Thomas P. Orsini, Patrick G. White, Russell T. Christman

Patent number: 11279574Abstract: A dispenser (200) includes a supply structure (202) and a biasing structure (206). The supply structure holds mailers (204). A mailer from the mailers includes a first wall and a second wall. The first and second walls are closed at a first side of the mailer, closed at a second side of the mailer, and closed at a closed end of the mailer. The first and second walls are not closed at an open end of the mailer. The mailer is arranged to be dispensed from the supply structure (202). The biasing structure (206) is arranged to engage the mailer as the mailer is dispensed from the supply structure (202). The biasing structure (206) has narrowing surfaces configured to contact the sides of the mailer as the mailer is dispensed. The narrowing surfaces of the biasing structure (206) are arranged to narrow the open end of the mailer thereby causing the open end to be biased open.Type: GrantFiled: April 12, 2019Date of Patent: March 22, 2022Assignee: Sealed Air Corporation (US)Inventors: Christopher C. Hamlin, Thomas P. Orsini, Patrick G. White, Russell T. Christman

Patent number: 11203452Abstract: A system includes a forming funnel, a cutting element, and a fusing device. The forming funnel has divergent surfaces arranged to receive a mailer in an insertion direction between the divergent surfaces. The forming funnel includes a slot that constrains the mailer after the mailer is inserted between the divergent surfaces. The cutting element cuts off a portion of the mailer and to forms a cut end of the mailer as the mailer is moved through the slot in a sliding direction. The fusing device applies pressure to an exterior of the cut end of the mailer and applies heat to the cut end of the mailer as the mailer is moved through the slot. The pressure and the heat applied by the fusing device cause portions of the cut end to fuse together to close the mailer.Type: GrantFiled: October 3, 2019Date of Patent: December 21, 2021Assignee: Sealed Air Corporation (US)Inventors: Christopher C. Hamlin, Thomas P. Orsini, Russell T. Christman
