A container lid and base assembly includes lid and base stacking features, as well as base chamfers that align with vents provided in the lid. When a plurality of the container assemblies is stacked, the lid and base stacking features nest with each other, while the chamfers align with corresponding vents in the stacked assemblies so that none of the vents is blocked by a next-higher container assembly. The stacking features can be centrally located, and the vents can be peripherally located. A plurality of the container assemblies can have differing sizes and/or shapes, while including mutually compatible stacking features, thereby enabling container assemblies of differing sizes to be stacked without blocking any of the vents thereof. The vents can be holes or “C” vents. The lid and/or base can be manufacturable by thermoforming. The lid and base can be separate, or joined by a hinge.

A lid for a container, such as a beverage cup, is provided. The lid includes a top wall for covering an opening of the container. The top wall may include an inner layer and an outer layer. The inner layer may include a first perforation line defining an openable sip hole area. The outer layer may be connected to the inner layer at the openable sip hole area. The outer layer may include a tearing off area that may be torn off and result in the opening of the first perforation line to create a sip hole in the inner layer.

A liquid container lid assembly enables a user to more effectively control liquid egression from a liquid container as outfitted with the lid assembly. The lid assembly includes a lower lid construction and an upper lid construction. The lower lid construction includes an upper-receiving depression having at least one liquid-letting aperture. The lower lid construction is removably attachable to an upper container rim of a liquid container and the upper-receiving depression includes concave upper portion surfacing. The upper lid construction is nestable in superior adjacency to the upper-receiving depression and includes a lower-opposing portion and a primary liquid outlet. The lower-opposing portion includes convex lower portion surfacing, which convex lower portion surfacing mimics the concave upper portion surfacing for eliminating gaps therebetween. The primary liquid outlet is orientable in superior adjacency to the lower lid construction for selectively outletting liquid received in an assembly-outfitted liquid container.

A container assembly including, a carton base having a substantially planar bottom surface, a lid having a top surface and a plurality of sidewalls extending therefrom. The lid is releasably engaged with the carton base and forms an interior space when engaged with the carton base. The top surface of the lid includes: a plurality of raised platforms, each raised platform having a substantially planar top surface, and a plurality of channels extending between each of the raised platforms such that each of the plurality of channels continuously extends to a perimeter of the lid. Additionally, the carton base is formed of three distinct laminate layers, with at least one of the laminate layers including a resin and a board weight of 200 g/m.sup.2 to 300 g/m.sup.2.

A venting device and method for the retention of food temperature and texture is disclosed. The venting device of the present invention is inserted through the top, outside surface of a food container sufficiently to allow the device to puncture the surface of the container and allow venting of the steam and moisture created from the hot food within the takeout food container.

A container lid and base assembly includes lid and base stacking features, as well as base chamfers that align with vents provided in the lid. When a plurality of the container assemblies is stacked, the lid and base stacking features nest with each other, while the chamfers align with corresponding vents in the stacked assemblies so that none of the vents is blocked by a next-higher container assembly. The stacking features can be centrally located, and the vents can be peripherally located. A plurality of the container assemblies can have differing sizes and/or shapes, while including mutually compatible stacking features, thereby enabling container assemblies of differing sizes to be stacked without blocking any of the vents thereof. The vents can be holes or “C” vents. The lid and/or base can be manufacturable by thermoforming. The lid and base can be separate, or joined by a hinge.

A two-part disposable, stackable and recloseable lid for a container holding a beverage. The lid has a dome configuration for higher volume beverages. The lid has a drinking aperture and an a moveable arm with a plug to seal the drinking aperture. The lid has a recess for storing the plug end of the arm when the drinking aperture is being used.

A packing sheet for discharging gas according to an exemplary embodiment of the present invention has a structure in which a first layer and a second layer, which are configured such that gas flows between one surface and the other surface, are stacked, and includes: a lamination portion which is formed by partially laminating the first layer and the second layer; and a gap portion which is a region other than a region of the lamination portion and has a space formed between the first layer and the second layer so that the gas flows in the space. According to the packing sheet for discharging gas, a space, in which gas may flow, is formed by partially laminating the first layer having fine bores and the second layer made of a gas-permeable waterproof material, and as a result, it is possible to prevent a liquid leakage while smoothly discharging the gas created in the container.

A one-piece part and a method of making the one-piece part. The one-piece part comprises an upper wall; a lower wall having an exterior portion and an interior portion, the interior portion overlapping the upper wall; lateral walls connecting the upper wall to the lower wall; an intermediate wall connecting the upper wall to the lower wall, the intermediate wall extending longitudinally between the lateral walls; a bottom wall connecting the lateral walls and the lower wall; and a top wall connecting the lateral walls and the upper wall, wherein the lateral walls, the top wall, the bottom wall, the exterior portion of the lower wall, the intermediate wall, and the upper wall have exterior surfaces and interior surfaces, the interior surfaces defining a volume of the one-piece part, and wherein the interior portion of the lower wall extends into said volume.
