A frame is injection molded onto a group of panels to form a container. The panels extend at least partially around, and at least partially define, a cavity of the container.

Injection-molded composite construct

A package is described. The package comprises a first wall, a second wall, and a first seal. The first wall comprises an exterior layer, an interior layer, and a peelable adhesive layer positioned between the exterior layer and the interior layer. The interior layer comprises a first Sine of weakness and a second Sine of weakness, and the peelable adhesive layer comprises a peelable adhesive region and a first void. The first void is aligned with the first Sine of weakness. The first seal is positioned between the first line of weakness and the second line of weakness, and a first end portion of the first seal is aligned with the first void. Various embodiments of the package are also described.

Package having peel reseal feature

A container that includes a microwave interactive web at least partially overlying and joined to a three-dimensional support, wherein the three-dimensional support may be formed prior to having the microwave interactive web mounted thereto. The three-dimensional support may be a preformed container that is sufficiently rigid and dimensionally stable for use in containing food.

System for forming constructs that include microwave interactive material

The present invention is directed to flexible peelable/resealable packages having a first wall panel which includes an abuse layer forming an exterior surface of the package with a printed release lacquer coating positioned on the abuse layer and a pressure sensitive adhesive coating positioned on the release lacquer coating which may be in direct contact with the sealant substrate forming a portion of the interior surface of the package.

Flexible peelable/resealable package

A structure is injection molded onto a group of panels to form a container. The container has a tray and an injection-molded feature. The tray has a plurality of side panels that extend at least partially around, and at least partially define, a cavity of the container. The tray has a plurality of multi-part flanges with at least one of the multi-part flanges including a lower flange portion and an upper flange portion. The injection-molded feature has band that is injected molded onto the lower flange portion and the upper flange portion. An injection-molded strip extends along and at least partially defines the corner of the container. The strip extends downward from the inner portion of the band in the elongate corner of the container. A tool is also disclosed for forming the container.

Tool for forming an injection molded composite construct

Various embodiments of flanged containers that can be stacked in a nested relationship are disclosed so as to provide uniform spacing between the containers to facilitate reliable denesting thereof. The flanges and/or sidewalls of the containers may be provided with features that facilitate alignment and uniform spacing of the nested containers so that a denesting apparatus can reliably denest the containers. Other containers include sidewalls divided into two sections that serve to stabilize stacked container.

Nestable container with uniform stacking features

Container with microwave interactive web

A method for forming a container having an injection-molded feature. The method includes obtaining a blank, forming the blank into a three-dimensional article having at least one sidewall, and forming the injection-molded feature extending around the perimeter of the article. The injection-molded feature comprises an anchor portion and a flange portion. The anchor portion is in contact with an interior surface of the at least one sidewall and the flange portion extends from the anchor portion outwardly from the at least one sidewall.

Container having a rim or other feature encapsulated by or formed from injection-molded material

A tool and method for forming a container from a construct. The tool comprising a cavity for receiving a construct, a core operatively associated with the cavity and being operable to move into the cavity, an injection cavity for receiving injection-molding material and directing injection-molding material around at least a portion of the perimeter of the construct, and a clamping feature. The clamping feature is operatively connected to at least one of the cavity and the core and is for clamping a peripheral portion of the construct as the core moves into the cavity to form the construct into the container.

Method for forming a container having an injection-molded feature

A method of forming a container from a construct. The method includes obtaining a tool having a cavity, a core, and an articulated section for being moveable within the cavity relative to the cavity and the core. The method further includes placing a construct between the cavity and the core, moving the core relative to the cavity so that the articulated section at least partially initially grips a portion of the construct, and further moving the core into the cavity. The portion of the construct remains gripped by the articulated section in the cavity during the further moving of the core.

Method of forming container with a tool having an articulated section

A package with self-forming insulating walls includes a tray for supporting a food item, a flap joined to the tray along a fold line, and an insulating microwave material overlying at least a portion of the tray and at least a portion of the flap. The insulating microwave material may be joined to the flap. The insulating microwave material may include a microwave energy interactive material supported on a first polymer film layer, a moisture-containing layer joined to the microwave energy interactive material, and a second polymer film layer joined to the moisture-containing layer in a predetermined pattern, thereby defining a plurality of expandable cells between the moisture-containing layer and the second polymer film layer.
