Abstract: A tamper-evident container can include a base and a lid. Each of the base and the lid can include a flange having a free edge that defines at least a portion of an outermost perimeter of the base or lid, respectively. The lid can include a tab that has an upper surface and a lower surface opposite the upper surface and a weakened region that borders a portion of the tab. When the lid is coupled to the base in a closed pre-use configuration, the lower surface of the tab is accessible from a lateral side of the container. The tab can be separated from a neighboring portion of the lid flange along the weakened region yet remain coupled with the lid and assist in uncoupling the lid from the base.

Abstract: A vent baffle can be arranged so as to direct air near an underside of a roof. The vent baffle can feature bending structures, which can allow the vent baffle to transition from a substantially columnar orientation to a bent orientation.

Abstract: A container can include a base, a lid, and one or more vents. The lid can be removed from the base and can be reattached to the base. Moreover, when the lid is attached to the base, it can permit self-venting of the container. Pressure within the container can cause the lid to move relative to the base so as to open the vents while the lid remains coupled with the base.

Abstract: A container can feature one or more venting regions that can be sealed when the container is in a first operational state and that can provide fluid communication between an interior volume of the container and an environment external to the container when the container is in a second operational state.

Abstract: A container (e.g., for food) has a top portion, a bottom portion connected to the top portion by a hinge, and a closure opposite the hinge. The closure is a tab-and-slot type, with the tab curved in a direction away from the slot to encourage closing and discourage opening of the container. A beveled edge on the top surface serves as a designated pressure-application area for a user's thumb, assisting with opening and/or closing of the closure with one hand. Mating step-type peripheral flanges in the top and bottom slope upward from the hinge to the closure to create a multi-level seal that gets larger near the closure. The step shape of the top flange also helps create a channel in the top that catches any liquid spilled on the container, and barriers on either side of the closure in the channel discourage the liquid from entering the container through the closure.

Abstract: A formed plastic container having a cover portion and a bottom portion, also includes a latch. The latch has a projection extending out from the cover, and a locking flap extending out from the bottom that flexes to meet and hold the projection. In one embodiment, the projection includes a tab, and the locking flap includes a rib that lifts the flap above the tab when closed, in order to reduce the possibility of the tab coming away from the flap.

Abstract: A container for housing a food dish includes a receiving shell defining a first cavity and a cover shell that is releasably lockable to the receiving shell for providing a cover with a second cavity over the first cavity. The cover shell has side walls with inward projections for entrapping the food dish seated within the receiving shell when the cover shell is releasably locked to the receiving shell.

Abstract: There is disclosed a process for producing alkenyl aromatic foams utilizing a combination of atmospheric and organic gases as blowing agent, preferably using greater than 30% by weight of atmospheric gas, and preferably also using a predetermined about of a masterbatch mix comprising a styrenic polymer, a rubbery block copolymer, and a solid blowing agent. Also disclosed are alkenyl aromatic foams produced by the process which exhibit increased densities, increased thermoforming capabilities, increased post-expansion properties, and increased retainment of the atmospheric and organic gases.

Abstract: A tabless container closure for a compartmentalized container with a cover and a base. The cover includes a sidewall and a rim coupled thereto. The rim has a depression that fits within an opening in a sidewall of the base. The rim depression and opening provide a snap-fit closure to releasably connect the cover and base. In a second aspect, the compartments of the container are closed off from one another such that the contents of a given compartment substantially remain therein, even after a perturbation of the container. In a third aspect, a divider separating the compartments is bowed to enhance the structural integrity of the base.

Abstract: A container closure for a container with a cover and a base. The cover includes a sidewall and a rim coupled to the sidewall. The rim includes a depression that takes the place of a male closure component. The base includes a sidewall and an opening in the sidewall for receiving the rim depression. The rim depression and receiving opening provide a snap-fit closure to releasably connect the cover and base.
