The present disclosure envisages a jig (100) for manufacturing a container with a rolled free edge. The jig (100) comprises a container fixture (110) and a rolling die (150). The container fixture (110) comprises a first set of split jaws (125) abutting an operative outer side of the container near the free edge of the container, and arranged to slide along the outer sides of the container, thereby supporting the outer sides during the rolling operation. The rolling die (150) of one embodiment comprises a second set of split jaws (165) having a rounded groove (155), the split jaws of said second set of split jaws are arranged to contract during the rolling operation.

A cup having a bottom and a sidewall attached to the bottom, wherein the sidewall preferably comprises a rolled rim at its upper edge opposite to the bottom, wherein the sidewall comprises a single layer or a plurality of layers, wherein at least one of the layers is produced from a paper or carton material, wherein at least one shaping is shaped into at least one of the layers of the sidewall, wherein the shaping is at least partially ring-shaped, wherein the shaping extends at least partially over the perimeter of the sidewall, wherein the shaping is inwardly or outwardly directed, wherein the shaping is compressed in height such that an edge of the shaping touches an opposite segment of the shaping and/or that both edges of the shaping touch each other and are joined together.

A container is formed to include an interior region and a mouth opening into the interior region. The container includes a floor and a side wall coupled to the floor to define the interior region between the floor and the side wall.

A paper lid for a container includes a body portion, a top lid portion having an outer periphery surrounded by the body portion, and an engaging portion in the body portion that includes a tapered portion tapering in the same direction as the container taper and engages with the container curl portion. The body portion has a first end portion for mounting on the container and an opposite second end portion. The outer periphery is bent toward the first end portion, and has a bent portion bonded to the body portion. A part other than the outer periphery is between the engaging portion and the second end portion. An inner diameter of a tip of the tapered portion is smaller than an outer diameter of the container curl portion. Where the lid closes the container opening, the container curl portion contacts an inner part of the tapered portion.

An apparatus for forming an upper edge of a paperboard container includes a pocket including a shell having a cavity with a mouth configured to receive the container along an axis such that the rim extends beyond the mouth. A workstation includes a forming member having a first forming surface which is actuatable toward the axis from a retracted position spaced from the rim to an extended position lying adjacent an upper end of the rim, and a forming segment having a second forming surface which is actuatable along the axis and the forming member in response to axial movement thereof such that the second forming surface is positioned spaced from a lower end of the rim. The second forming surface is actuatable along the axis towards the first forming surface to form the rim therebetween.

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.

A paperboard servingware container is provided. This paperboard servingware container may include a bottom panel; a curved transition portion located at the periphery of the bottom of panel. An upwardly extending wall extends from the curved transition portion opposite the bottom panel. An angled peripheral transition located adjacent the upward extending wall opposite the curved transition portion. A ledge portion that extends from the angled peripheral transition opposite the upward extending wall and away from the upward extending wall. A folded over flange portion that is bent downwardly with respect to the ledge portion.

A container is formed to include an interior region and a mouth opening into the interior region. The container includes a floor and a side wall coupled to the floor to define the interior region between the floor and the side wall

1. Paper cup, and method and device for making a paper cup. 2.1. The invention relates to a paper cup with a cup sleeve and a bottom connected in a liquid-tight manner to the cup sleeve. 2.2. In accordance with the invention, the cup sleeve is arranged between the bottom and an end opposite the bottom at least in some sections at an angle greater than or equal to 10, in particular between 10 and 15, relative to a central longitudinal axis of the paper cup. 2.3. Use for example for paper cups of plastic-coated paper material.

A cup having a bottom and a sidewall attached to the bottom, wherein the sidewall preferably comprises a rolled rim at its upper edge opposite to the bottom, wherein the sidewall comprises a single layer or a plurality of layers, wherein at least one of the layers is produced from a paper or carton material, wherein at least one shaping is shaped into at least one of the layers of the sidewall, wherein the shaping is at least partially ring-shaped, wherein the shaping extends at least partially over the perimeter of the sidewall, wherein the shaping is inwardly or outwardly directed, wherein the shaping is compressed in height such that an edge of the shaping touches an opposite segment of the shaping and/or that both edges of the shaping touch each other and are joined together.
