A tamper evident container includes a cover comprising a first interlocking flange with a first inner tab and a first outer tab separated by a first severable line and a base comprising a second interlocking flange with a second inner tab and a second outer tab separated by second severable line, where the first and second interlocking flanges are configured to be fastened together and the container is configured to be opened by separating the first and second inner tabs from the respective first and second outer tabs while one of the first and second outer tabs remains attached to the container and another of the first and second outer tabs is separated from the container and remains attached to the one of the first and second outer tabs.

A method of forming an undercut which is engageable with an edge, on a side wall of a cover intermediate body using a cover intermediate body and a secondary processing die. In the secondary processing die, a moving inner core has, on the outer surface thereof, a concave shape corresponding to a convex shape of the inner surface of the undercut. The moving inner core is made up of a plurality of core segments which are arranged along the circumferential direction. Each core segment is vertically movable along an inclined surface of a core. When the moving inner core is moved upward, the moving inner core transforms smaller than the inner diameter of the side wall of a cover. The slide core has, on the inner surface thereof, a convex shape corresponding to the concave shape of the undercut.

A container having a pair of side walls and end walls and corner walls being provided between a respective end wall and side wall, a flange formed on one of the corner walls, said flange functioning as a hinge, a ring member formed integrally with the flange, the ring being sized to sit on top of the container.

A sheet of polymeric material is made using an extruding process and articles are formed from the sheet of polymeric material. The sheet of polymeric material and the articles comprise one or more polypropylene resins. In some embodiments, the sheet of polymeric material and the articles formed form the sheet of polymeric material are transparent.

A recloseable lid for closing an open top of a cup terminating in an annular upper edge includes a cup mount defining an annular channel configured to receive the annular upper edge of the cup and a cap having an annular side wall extending upwardly from the cup mount and terminating in a top having an annular floor spaced above the cup mount. A drink opening is disposed in the top and a plug assembly having a drink opening plug is provided. The drink opening plug can be selectively moveable between a closed position in which the drink opening plug is received within the drink opening for closing the drink opening and an open position in which the drink opening plug is not disposed within the drink opening. The lid can also include a plug retainer disposed in the cap and configured to retain the drink opening plug in the open position.

A packaging container includes a base section having a U-shaped perimeter wall and a cover section having a cover outer wall, the cover section adapted to cover the base section when in a closed state. The packaging container includes a closure mechanism including an aperture formed within an outer wall segment of the base section and a projection extending inward from the cover outer wall for engaging the outer aperture of the base section. The closure mechanism retains the cover section over the base section and securing the packaging container in a closed position, wherein an obstructive member obstructs movement of the inner wall segment of the base and prevents the projection from being released from the outer aperture. A release tool is provided for being inserted between the cover outer wall and the base outer wall, wherein the release tool is adapted to move the cover outer wall outwardly to release the projection from the outer aperture, thereby opening the packaging container.

A storage lid and a cookware assembly are provided that includes a cover portion having a top surface, first and second sidewalls and a flexible locking tab. The first and second locking tabs each have a lateral portion and a locking portion. The lateral portion has an inner surface and an outer surface and extends outwardly from the sidewall in a direction that is generally parallel to the top surface of the cover portion. The locking portion extends downwardly and inwardly at an angle from the lateral portion. A locking protuberance is disposed on the inner surface of the locking portion, and an elongate aperture that terminates proximate the locking protuberance is disposed in a portion of the lateral portion and the locking portion.

A package having a container and a selectively openable lid to selectively allow access to the container is disclosed.

A container includes a base, a cover and an intermediate part. The base includes a first room and a first lip extends from the open top of the base. The cover includes a second room and a second lip extends from the open bottom of the cover. The intermediate part includes a third room and a third lip extends from the open top of the third room. The cover is mounted to the base with the intermediate part located between the cover and the base. The cover seals the base and the intermediate part by one-time pressing action. The base includes at least one plate which is engaged with a recess formed to the outside of the second lip of the cover to secure the cover to the base.

At least some example embodiments relate to a container including a body and a lid. The body includes a base, a side wall, and an interior region at least partially defined by the base and the side wall. The lid includes a lid wall and a skirt that extends from a periphery of the lid wall. The skirt engages the body to retain the lid on the body. The skirt cooperates with the lid wall to define a cavity. The lid is formed from a laminate including a metal layer and a polymer layer coupled to the metal layer. The polymer layer is disposed inside of the metal layer with respect to the cavity. A portion of the body is disposed inside the cavity when the container is in a closed configuration. At least some example embodiments relate to a forming of manufacturing the lid.
