Abstract: Thermoformed locking assembly comprising a first web portion including locking lug having lug undercut defining a cantilevered lug ledge having lug engaging surface, second web portion including locking recess having recess undercut defining an opposing recess ledge having recess engaging surface and a lug stop opposite the recess undercut. Locking recess configured to receive locking lug and lug stop configured to position locking lug in locking recess with the lug engaging surface in engagement with the recess engaging surface when first web portion is moved towards second web portion.

Abstract: Unitary blank for forming a cup sleeve is provided having a central body portion, a first side body portion, and a second side body portion, a central flap extending from the central body portion, a first flap extending from the first side body portion, the first flap including a first tab, and a second flap extending from the second side body portion, the second flap including a second tab. In addition, at least a selected surface area of the blank has a pattern of raised features. Raised pattern areas of inner fold-over flaps can overlay corresponding raised pattern areas of sleeve outer body panels thereby increasing a size or volume of air gap pockets created between inner flaps and outer body panels. A multi-layer cup sleeve and a method for forming a cup sleeve are also provided.

Abstract: Tamper-evident plastic container comprises a base portion having a sidewall and a base flange extending outwardly from at least a portion of the sidewall, as well as a lid portion having a lid tab joined to the base flange by a hinge, wherein the lid portion has an open position and a closed position. The lid portion is configured to lockingly engage the base portion in the closed position. One of the base flange or the lid tab has a non-linear path of weakness formed therein to define a frangible connection, wherein the frangible connection is configured to be ruptured to initially open the lid portion from the closed position. The non-linear path of weakness is spaced from the hinge to define a tamper indicator region between the non-linear path of weakness and the hinge, wherein the tamper indicator region remains joined to the hinge after the frangible connection is ruptured. Methods of containing a product in a tamper-evident container are also disclosed.

Abstract: Method of forming a container having a rolled rim, including providing a thermoformable sheet, and thermoforming the sheet to form a hollow body. The hollow body has an open first end and an opposite closed second end with a sidewall extending between the first end and the second end, and a rim structure formed at the first end of the hollow body. The rim structure includes an inner wall portion, a flange, and a skirt. The method further includes coining an upper section of the inner wall portion of the rim to form a controlled inner diameter, and rolling the rim structure to form a rigid rolled rim along an outer diameter of the open first end of the hollow body, the skirt extending toward the sidewall after being rolled.

Abstract: Mineral-filled polymer compositions and methods of forming such polymer compositions into a thermally stable article are provided. Methods of forming a polymeric article include providing a polymer composition comprising a crystallizable polymer, a mineral filler in an amount of more than about 15 wt-% based on the total weight of the polymer composition, and an impact modifier, wherein the polymer composition is at a temperature less than a crystallization temperature of the crystallizable polymer. The methods further include disposing the polymer composition in a mold, forming the polymer composition into an article within the mold, and releasing the article from the mold. The methods can include thermoforming the polymer composition in a mold, or injection molding the polymer composition in a molten form in a mold.
