A pill sorter with bag sealer designed for the dispensation and storage of easily transportable packages of medication. The pill sorter has one or more independent chambers that can store pills or other medication. The pill sorter dispenses medication through a funneled lid, allowing the user to dispense a single chamber's medication into a plastic bag. The plastic bag is placed into a bag sealer having an activation button, light-emitting diode (LED), battery, microprocessor, and sealing element. The activation time of the sealing element is adjusted by the microprocessor based upon the measured level of charge present in the battery, providing a one-touch sealing solution to the user. The sealing element seals the plastic bag, which has a perforated seal, allowing for easy opening of the plastic bag when the medication is needed.

The invention relates to a welding tool and a method for pulse welding films of plastic for medical packs formed as bags. The invention generally provides for the film material that has been plastified during welding, and is consequently free-flowing, to be specifically displaced by increasing the sealing surface area. The displaced film material can for instance compensate for dimensional and form tolerances. At the same time, however, the strength of the welded seam region, which adjoins the interior space of the bag, is not reduced.

A protective packaging formation device is disclosed herein. The device includes an inflation assembly that directs fluid between first and second overlapping plies of a web material. The device also includes a sealing mechanism that includes an arcuate web-support surface. The web-support surface includes a heater that defines a heating zone that is operable to heat the plies to create a longitudinal heat seal that seals the first and second plies together as the web is driven over the heating zone in a downstream direction. The web-support surface also includes a cooling zone disposed downstream of the heating zone operable to allow the heated plies to cool at the longitudinal heat seal as the web is driven over the heating zone in a downstream direction, such that the cooled longitudinal heat seal retains the fluid between the plies.

Presented are repair systems for fixing filler-reinforced polymer structures, methods for making/using such repair systems, and techniques for repairing surface damage/defects of multidimensional fiber-reinforced polymer (FRP) panels. A repair system for fixing a contoured surface of an FRP structure includes a flexible contact sheet that is fabricated from a thermally stable polymer, and has a textured contact surface that seats on the FRP structure and overlays the damaged area. A rigid cover sheet, which may be fabricated from a metal material, a polymeric material, and/or resin-impregnated fiber, has a complementary surface that conforms to the contoured surface of the FRP structure and covers the flexible contact sheet. The repair system also includes a heating element that lays against the rigid cover sheet and applies heat to the contoured surface with a substantially uniform profile that is sufficient to soften/melt portions of the FRP structure neighboring the damaged area.
