Abstract: The present disclosure relates to medical delivery devices that include a barrel having an inner surface, and in at least one embodiment, the inner surface is hydrophilic. The medical delivery device may further include a stopper may having an elastomeric body, one or more fluoropolymer layers, and two or more ribs laminated to the one or more fluoropolymer layers. In some embodiments, the contact angle of the inner surface of the barrel is less than about 58°. Additionally, the stopper includes a sliding surface that is less than about 2.0 mm. The barrel provides inner surface that in combination with the fluoropolymer laminate or fluoropolymer film achieve high levels of air and liquid impermeability while also maintaining an acceptably low break loose force, low average glide force, and low glide force variation. In some embodiments, the compressibility stopper against the barrel is greater than about 7.9%.

Abstract: Disposable platters are provided. In at least one embodiment, a disposable platter can include a bottom panel made of paper, a sidewall that can extend upwardly from the bottom panel, an outer flange that can extend outwardly from the sidewall, a first transition that can extend upwardly and outwardly from the bottom panel to a first end of the sidewall, and a second transition that can extend outwardly from a second end of the sidewall to a first end of the outer flange, defining a radius of curvature, R2, therebetween. In some examples, the platter can have at least two sides of different lengths, a characteristic diameter, D, that is an average length of the sides, and a ratio of R2/D that is 0.0125 or less.

Abstract: Pressware stacking systems and methods for using same. The system can include a conveyor for moving pressware in a first direction; a stop ramp at least partially disposed on the conveyor; and a lifter in communication with the stop ramp. The lifter is adapted to move at least a portion of the stop ramp to an inclined position above the conveyor.

Abstract: Disposable platters are provided. In at least one embodiment, a disposable platter can include a bottom panel made of paper, a sidewall that can extend upwardly from the bottom panel, an outer flange that can extend outwardly from the sidewall, a first transition that can extend upwardly and outwardly from the bottom panel to a first end of the sidewall, and a second transition that can extend outwardly from a second end of the sidewall to a first end of the outer flange, defining a radius of curvature, R2, therebetween. In some examples, the platter can have at least two sides of different lengths, a characteristic diameter, D, that is an average length of the sides, and a ratio of R2/D that is 0.0125 or less.

Abstract: The present invention relates to rigid-buckling-resistant-fluted containers with an arcuate outer rim. The container such as a pressformed paperboard plate of overall diameter “D” including a generally planar bottom region, an upwardly extending fluted region surrounding the generally planar bottom region, and an outwardly and downwardly extending peripheral region having an arcuate radial profile. The containers being produced of a lightweight board but exhibiting high strength and rigidity relative to the low weight board.

Abstract: A pressware stacking assembly and method for using the same are provided. The stacking assembly may include a stacking surface for supporting a plurality of pressware products and at least one shaped wheel at least partially disposed through the stacking surface. The shaped wheel may include a body having at least three sides disposed about a perimeter thereof and at least one transition section disposed between adjoining sides, wherein each transition section is adapted to lift at least a portion of the pressware products off the stacking surface.

Abstract: Embodiments of the invention provide improvements to dies used in the formation of pressware from blanks. In some embodiments, the die includes at least one stop that helps contain the blank as it is fed to the die and that allows for improved adjustability of the stop with respect to the die. In some embodiments, the die includes a defined recess that contains and centers the blank on the die as the blank is fed to the die.
