20150367980 | CONTAINER HAVING A DIVIDER, A LID, FOLDABLE SUPPORTS, AND INWARDLY FOLDING PANELS - Unitary blank can include a first body portion, a second body portion joined to the first, a third body portion joined to the second, and a fourth body portion joined to the third. A first flap can extend from the fourth body portion and can have a first engagement portion adjacent to the fourth body portion, a second engagement portion opposite the fourth body portion, and a central portion defined therebetween. At least one inwardly folding panel can be disposed between adjacent body portions along a corresponding body fold line. First, second, third, and fourth base portions can extend from the first, second, third, and fourth body portion, respectively. Food containers and methods are also provided. | 12-24-2015 |
20150060456 | ENHANCED TAMPER EVIDENT BOWL WITH BLOCKED TAB - A container which includes a base ( | 03-05-2015 |
20140262909 | Cake base with recesses - Base for a food container includes a base member having a perimeter and a central region, a retaining ring of height H and width W formed between the perimeter and the central region, and extending upwardly from the central region, and a plurality of recesses in the retaining ring, each recess extending across the width W of the retaining ring from the perimeter toward the central region of the base member. Container further includes a lid having a perimeter configured to engage the perimeter of the base member. Method of making a food container is also provided. | 09-18-2014 |
20140187658 | Reduced-VOC and Non-VOC Blowing Agents for Making Expanded and Extruded Thermoplastic Foams - Process for producing a thermoplastic polymer foam article includes preparing an expandable polymeric formulation comprising a thermoplastic polymer and a blowing agent blend, forming the formulation into an expandable bead, and expanding the expandable bead to form a thermoplastic polymer foam article. The blowing agent blend includes methyl formate, hydrocarbon, and either carbon dioxide or 1,1,1,2-tetrafluoroethane (HFC-134a). The blowing agent blend has a higher effective volatility than that of methyl formate alone. A thermoplastic polymer foam article prepared by a process is also provided. | 07-03-2014 |
20140131367 | MULTILAYER ARTICLE AND METHOD FOR MAKING A MULTILAYER ARTICLE, BLANK, AND INSULATING CUP - Method of making a multilayer article including providing a first substrate and providing a second substrate. The method further includes disposing an expandable insulating material on an inner surface of at least one of the first substrate and the second substrate, wherein the expandable insulating material is in a first condition during disposing. The second substrate is adhered to the first substrate with the expandable insulating material therebetween to form a blank, wherein an insulating space is defined between the first substrate and the second substrate with the expandable insulating material therein and the insulating space includes a first volume. The method further includes forming the blank into the article and expanding the expandable insulating material to a second condition by application of energy, wherein the expandable insulating material in the second condition increases the insulating space to a second volume. | 05-15-2014 |
20130313257 | Food Storage Container Closure - Container includes a base and a lid. The base has a base rim forming a base channel including a bottom wall, an inner sidewall, and an outer sidewall to define a channel space, a lock projection extending into the channel space from a first portion of the base rim, and a lever projection extending substantially outwardly from a second portion of the base rim. The lid has a lid rim forming a lid channel including a bottom wall, an inner sidewall, and an outer sidewall. The lid has a closed position in which the lid channel is aligned with and disposed at least partially within the channel space. The lever projection is configured to pivot upon application of an external force to cause the lock projection to move out from the channel space and to urge at least a portion of the lid rim out of the base channel. | 11-28-2013 |
20130011648 | Reduced-Voc and Non-Voc Blowing Agents for Making Expanded and Extruded Thermoplastic Foams - A blowing agent blend for making thermoplastic polymer foams includes methyl formate. The blowing agent blend can further comprise at least one co-blowing agent. The co-blowing agent is either a physical co-blowing agent (e.g. an inorganic agent, a hydrocarbon, a halogenated hydrocarbon, a hydrocarbon with polar, functional group(s), water or any combination thereof), or a chemical co-blowing agent, or combinations thereof. The thermoplastic polymer foam can be an alkenyl aromatic polymer foam, e.g. a polystyrene foam. The blowing agent blend includes methyl formate and one or more co-blowing agents. The methyl formate-based blowing agent blends produce dimensionally stable foams that have improved resistance to flame spread. A process for the preparation of such foams is also provided. | 01-10-2013 |
20130011647 | Reduced-Voc and Non-Voc Blowing Agents for Making Expanded and Extruded Thermoplastic Foams - A blowing agent blend for making thermoplastic polymer foams includes methyl formate.

The methyl formate-based blowing agent blends produce dimensionally stable foams that have improved resistance to flame spread. A process for the preparation of such foams is also provided. | 01-10-2013 |
20120267368 | DISPOSABLE LID HAVING POLYMER COMPOSITE OF POLYOLEFIN AND MINERAL FILLER - Disposable lid comprises a thermoformed sheet in the shape of a lid for a hot beverage container. The sheet comprises a polymer composite of a polyolefin and at least one mineral filler. The sheet has a thickness less than about 0.035 inches and a heat deflection temperature at least comparable to that of high impact polystyrene. | 10-25-2012 |
