20120234717 | Multi-Tiered Cupcake Container - Tray includes a first base portion having an upper surface defining a first tier and a second portion having an upper surface defining a second tier. The first tier and the second tier are separated by a height. The upper surface of the first portion and the upper surface of the second portion each have a plurality of spaced-apart wells defined therein. Each well is sized and shaped to receive a food item and has an upper edge with an engagement recess formed therein. The engagement recess is sized to allow a food item within the well to be gripped for removal. The tray can further include a trapping feature to secure a lid, and thus form a container. | 09-20-2012 |
20110217492 | APPARATUS AND METHOD FOR MANUFACTURING REINFORCED CONTAINERS - Various embodiments of the apparatus and methods are configured to make containers such as disposable reinforced cups using reinforcing members configured to be respectively attached to cups. The apparatus and method of various embodiments of the present disclosure sequentially heat different or selective portions of the heat activated adhesive on the reinforcing member at multiple sequential stages, steps or times to attach the reinforcing member to the container. | 09-08-2011 |
20110173910 | COMPOSITE ROOFING BOARDS AND METHODS FOR INSTALLING A COMPOSITE ROOFING BOARD - Composite roofing boards and methods for installing a composite roofing board are presented herein. In one embodiment, the roofing board comprises at least nine layers: two outer polymeric layers; two adhesive layers disposed between the two outer polymeric layers; two inner polymeric layers disposed between the two adhesive layers; and a substrate layer disposed between the two inner polymeric layers. A polymeric adhesive, such as an acrylate-polymer adhesive, is preformed on an outer surface of the first and/or second outer polymeric layer. A removable release liner, such as a siliconized polyester film, covers the polymeric adhesive. | 07-21-2011 |
20110033138 | PACKAGE CLOSURE FOR WITHSTANDING INTERNAL FORCES - A reclosable package comprises a first panel having first and second side sections and a second panel having first and second side sections. The first panel opposes the second panel and is joined to the second panel along the first and second side sections. A bottom extends between the first and second side sections of the first and second panels with the first and second panels joined to each other. A mouth is disposed opposite the bottom and extends between the first and second side sections of the first second panels. A closure member extends along the mouth, with the closure member including a first fin joined to the first panel and second fin joined to the second panel. A sealing member having a first and second ends is disposed proximate the mouth. The ends of the sealing member can be attached to the fin or panel such that at least one of the first end or second ends of the sealing member is attached with peelable seal. | 02-10-2011 |
20100279840 | METHOD OF PERFORMING UNIT OPERATIONS ON A WEB WITH AN ATTACHED ZIPPER - The present invention relates to a process used for packaging a product in a web of material that has a zipper attached thereto. The process includes providing a web of material having first and second edges and a zipper including first and second interlocking members. The first and second interlocking members of the zipper are interlocked together. The first interlocking member of the zipper is attached to the web at an intermediate portion of the web between the first and second edges of the web. The second interlocking member has an attachment region that is facing away from the web. One edge of the web is folded away from the zipper and toward the other edge of the web. Unit operations are performed on the zipper to create zipper segments from the zipper while the zipper is exposed. Each of the zipper segments is associated with an individual food package made from the web. | 11-04-2010 |
20100276478 | CONVERTIBLE CONTAINER AND PLATE - Foldable container including a base having a first base portion and an opposing second base portion. The base has a base surface free of hinge lines between the first base portion and the second base portion. A sidewall surrounds at least a portion of the base and extends generally upward from the base with a non-uniform height to define a compartment. A rim having a first rim portion and an opposing second rim portion is disposed proximate the top edge of the sidewall. At least one transition region is formed in the sidewall to allow the first base portion to pivot between an open position and a closed position. When in the open position, the container defines a plate. When in the closed position, the first base portion defines at least a portion of a cover relative to the second base portion. A packaged product is also provided, including a foldable container and a cover member removably attached to the rim of the foldable container in the open position to contain a product therein. | 11-04-2010 |

20100101055 | Reclosable Fasteners Or Zippers For Use With Polymeric Bags - A slider is adapted for use with a reclosable fastener for bags containing material. The reclosable fastener includes a first track and a second track. The first track includes a first profile, while the second track includes a second profile. The first and second profiles are releasably engageable to each other. At least one of the first and second profiles has an interior portion. The slider comprises a body that includes a top, a first side, a second side and a separation member on an underside of the top. The separation member is adapted to open and close the fastener and includes a slider finger that extends generally downwardly from the top. The slider finger extends into an interior portion of the first profile so as to assist in removing material trapped in the interior portion of the first profile when closing the reclosable fastener. | 04-29-2010 |
20090286023 | Polymer films with treated fillers and improved properties and products and methods using same - A multi-layer polymer composite film comprising at least a first layer of polymer material and a second layer of polymer material, at least one of the first layer and the second layer further including, a treated filler having a median particle size of about O.1 nm-1O μm, the treated filler dispersed throughout the polymer material of the at least one of the first layer and the second layer. | 11-19-2009 |
20090123728 | Polymer Blends Of Biodegradable Or Bio-Based And Synthetic Polymers And Foams Thereof - The present invention relates to compositions comprising blends of alkenyl aromatic polymers such as styrenic polymers (i.e. PS and HIPS) and bio-based or biodegradable polymers (i.e. PLA, PGA, PHA, PBS, PCL) compatibilized with styrene-based copolymers (i.e. styrene-ethylene-butylene-styrene (SEBS) block copolymers, maleated SEBS, styrene-maleic anhydride (SMA) copolymer, styrene-methyl methacrylate (SMMA) copolymer) or a mixture of two or more styrene-based copolymers such as SEBS and SMA. These novel compositions can be extruded and thermoformed to produce very low density food service and consumer foam articles such as plates, hinged lid containers, trays, bowls, and egg cartons with good mechanical properties. | 05-14-2009 |
