International Classification:

B31B 4902

US Classification:

493159

Abstract:

Apparatus for lubricating and curling a rim of a paperboard container includes a housing block defining a central recess sized and configured to accept therein a rim of a paperboard container to be curled. An annular curling channel is disposed in the recess for curling the rim of the paperboard container in response to relative advancing movement between the paperboard container and the housing block. The housing block also defines an annular liquid channel concentrically disposed in surrounding relationship to the annular curling channel for distributing lubricating liquid. A porous liquid transfer ring is attached to the housing block in covering relationship to the annular liquid channel so that lubricating liquid supplied to the liquid channel comes into contact with the liquid transfer ring. The liquid transfer ring includes a circular edge surface which defines a central opening such that the liquid transfer ring extends at least partially over the curling channel. In use, the rim of the paperboard container comes into wiping contact with the central opening of the liquid transfer ring so that lubricating liquid is transferred thereto prior to the rim being curled in the curling channel.

International Classification:

B31B 190

US Classification:

493109

Abstract:

A tamper evident container assembly includes a container body having a bottom wall and peripheral side wall, the side wall terminating in an outwardly curled rim. A reusable lid includes a top wall portion and a depending skirt portion, the depending skirt portion constructed of spiral wound stock and having a free end, a major peripheral portion of the free-end rocked under the upper rim and upwardly into engagement with the side wall, with a minor peripheral portion of the free end left untucked to thereby provide a gripping area to facilitate tearing and removal of the tear strip. The depending skirt portion is further provided in a lower portion thereof with a line of weakening extending annularly about the skirt portion to thereby define an annular removable tear strip inclusive of the free end, with the line of weakening lying on the rim, between upper and lower edges of the rim. Apparatus for forming the assembly includes a device for pressing a lower portion of the depending skirt portion of the lid under and into engagement with the rim of the container to form a curl about a major peripheral portion of the lid while leaving a minor peripheral portion uncurled while simultaneously forming a vertical slit in the lower portion of the depending skirt portion at an interface between the curled and uncurled portions to thereby simultaneously form a grip tab. Another device is provided for orienting the container to a predetermined rotational position prior to securing the lid.

International Classification:

B65D 1740

US Classification:

220276

Abstract:

A tamper evident container assembly includes an open-ended container body having a bottom wall and peripheral side wall, the side wall having an upper rim protruding radially outwardly of the peripheral side wall. A reusable lid has a top wall and a portion of which is tucked under the upper rim to thereby lock the lid to the container body. The depending skirt is further provided in a lower portion thereof with an annular line of weakening extending about the skirt portion to thereby define an annular tear strip inclusive of the free end so that upon removal of the tear strip, the lid may be removed from said container. A related method of assembling a tamper evident container assembly the steps of: a) filling the container body with contents; b) applying the lid to the container body; and c) tucking a substantial portion of the lower free edge under the rim to thereby provide a tamper evident container.
