An insulating container may include an opening, which can be sealed by a closure. The closure may have an upper portion with a handle that has a circular curvature equal to the cylindrical portion of the closure. The closure may also have a lower portion that is joined to the upper portion by an injection molded polymer element. The closure may also be in the form of flip type of closure such that the lid can be selectably opened or closed by the user by rotating a flip closure into either the opened or closed position. The closure may also be a two-part lid having a lower cap that may be configured to be removably-coupled to the container and an upper cap that may be configured to be removably-coupled to the lower cap

The dual-chambered liquid container canteen of the present invention includes a dual-chambered container with a vertical partition separating each chamber, the dual-chambered liquid container of the present invention includes a dual-chambered container with a vertical partition separating each chamber, three interchangeable lids with two separate non-removable inner wall compartments that fits inside each chamber of the container and securely separate the liquids while ensuring proper positioning of the lid over each compartment. A gasket molded into the rim of the container and vertical partition of the container to ensure a liquid airtight seal between each chamber and the lid, a gasket molded into the rim of the container and vertical partition of the container to ensure a liquid tight seal between each chamber and the lid, each lid has release holes for venting the container chambers to atmosphere as liquids are dispersed from the container.

A method for dielectrically heating foamable composition to foam and set the composition is described. In particular, radio frequency (RF) heating is used to heat the foamable composition to provide insulation in the manufacture of an article.

An insulating cup includes an outer body surrounding at least a portion of an inner body. The outer body folds inwardly and upwardly at the bottom end to form a distal fold that spaces the inner surface of the outer body at the bottom end away from the outer surface of the inner body. The outer body further includes an embossment across the majority of the length and width of the sidewall such that the inner surface of the outer body projects outwardly away from the inner body to space apart the inner surface of the outer body from the outer surface of the inner body in the location of the embossment. The distal fold and embossment separate the inner body and the outer body creating an insulating air space between substantially the entire inner surface of the outer body and the outer surface of the inner body.

A method for forming an overwrap container includes the steps of a) providing a base container having a first side seam on a side wall that extends along a longitudinal axis to define an internal volume, and a bottom secured to the side wall; b) providing the side wall of the base container with connecting elements on an outer periphery of the side wall; c) providing an overwrap having a second side seam over the side wall of the base container such that the overwrap is joined in spaced apart relationship by the connecting elements to the side wall of the base container; d) clamping the overwrap to the base container along the second side seam to form a first compressed area; e) clamping the overwrap to the base container in an area 180 removed from the second side seam to form a second compressed area: and f) reforming the second compressed area to define an overwrap container having a substantially uniform spacing and air gap between the base container and the overwrap except in the first compressed area.

A curled-edge and double-layered cup includes an outer cup unit including an outer base wall, an outer surrounding wall, and an outer top wall, and an inner cup unit disposed within the outer cup unit. The inner cup unit includes an inner base wall disposed above the outer base wall, an inner surrounding wall surrounded by the outer surrounding wall, and a curled-edge unit enclosing the outer top wall. The curled-edge unit includes an inner top wall disposed above the outer top wall, and an outmost surrounding wall having a surrounding portion connected to the inner top wall and surrounding the outer top wall, and a bottom seal portion extending inwardly from the surrounding portion and disposed under the outer top wall.

An insulated container includes a double-walled structure having a closed end, an open end, and a side wall extending from the closed end to the open end. The side wall and the closed end of the insulated container together form a hollow interior. A glass structure may be arranged within the hollow interior. The glass structure includes a body having an open upper end and a closed base end. According to an aspect, the insulated container includes a cover having a sipping portion. According to an aspect, the glass structure includes a sipping portion protruding from the double-walled structure, and a collar is positioned over the sipping portion of the glass structure.

A double-walled container is used to thermally isolate a stored substance from the external environment. The double walled container has an interior container, an exterior sidewall a flat base and a spacer ring. The interior container serves as a receptacle into which the stored substance is placed. The exterior sidewall is mounted onto the flat base so that the double walled container can be rested on a surface. The spacer ring is connected in between a rim of the exterior wall and a rim of the interior container. Thus connected, the spacer ring maintains the interior container in a position offset from the exterior sidewall. This enables an insulating compartment to be positioned in between the two components. Thereby, thermally isolating the interior container from the exterior sidewall.

The present paper cup comprises a cup body, and the cup body comprises inner paper and outer paper. There are hollow bulges on the outer paper, and the outer paper forms a connecting part. The inner side of the connecting part bonds to the outer side of the inner paper, and the cup rim of the outer paper extends to the cup rim of the inner paper. In addition, the outer side of the cup rim of the inner paper bonds to the inner side of the outer paper, and both cup rims of the outer paper and the inner paper bend outward to form a double layered crimping. The manufacturing process for the present paper cup includes: paper preparation, rolling, composition, sheet cutting, forming, molding and etc.
