    摘要: A clamshell container has a lid connected to a base by an integral hinge. The lid has a perimeter projecting member which engages with a peripheral base sealing wall in a closed configuration so that it is difficult for a user to open the container without tearing the lid along a weakened region of material along the hinge. To aid in resisting undetectable tampering, the container has a post which projects from the side wall and extends less than the length of the side wall within the container. The post has an engaging wall which faces towards a base sealing wall and which is spaced from the sealing wall to define a gap which receives the closed lid's projecting member. Distortion of the closed container which tends to urge the lid projecting member away from the base sealing wall engages it with the post engaging wall to resist tampering.

    摘要: A flexible reclosable thermoformed thermoplastic container is disclosed which has a base with side walls and a peripheral shoulder extending from the side walls which has a downwardly depending rim. The cover of the container has peripheral edges with depending side walls and is preferably attached by an integral hinge to the base. The cover is adapted to close upon and cover the base. A locking tab with two opposed faces spaced to fit between the base rim and side walls is connected by an integral hinge to the cover. The locking tab of the cover may be rotated about the integral hinge and inserted between the side wall and rim wall of the base to close the container. Containers with depressions in the base or cover side walls to facilitate opening are also disclosed. Containers may have two locking tabs connected on opposite sides of the cover by integral hinges which permit the cover to be removed entirely from the container. By providing unclasped cover portions on such a container, a self-venting container may be formed. By providing a ridge on the base beneath the locking tab, the cover may be fixably attached to the base.

    摘要: A method and apparatus are disclosed for holding and feeding a continuous sheet (12) of plastic in an operation such as thermoforming. Articulations (13), such as alternating waveforms, are formed on the edges of the plastic sheet (12) by heating and pressing the edges, producing inwardly facing abutment surface at the edges of the sheet. The sheet is then passed into slots (34) in guide rails (32) with the inside surfaces (35) of the guide rails (32) engaging the abutment surfaces on the plastic sheet (12) to prevent the sheet from slipping out of the guide rails. The plastic sheet is thereby held firmly so that it can be passed through such thermoforming operations as heating in an oven (14), forming with a mold at a forming station (40), and cutting the formed articles away from the remainder of the sheet by a trim press (53). The sheet is advanced in increments through the thermoforming apparatus by a sheet advance mechanism (48) which alternately grasps the sheet to advance it and then releases the sheet while the forming and trimming operations are carried out. Sheet stretching guide rails (90) hold the sheet at the mold and are mounted to move outwardly to stretch the heated sheet as the mold engages the sheet. The stretch on the sheet is released as the mold disengages. The stretching of the sheet during forming compensates for the tendency of the formed sheet to shrink as it cools.

    摘要: A system of containers forming a group of two and three containers, where one and two smaller containers can be positioned on a lid of a larger container so as to prevent sliding motion of the smaller containers. Each of the smaller containers having a bottom wall of substantially the same dimensions with a portion of the bottom wall forming an upwardly extending indentation. The small containers are formed with upwardly opening walls and have lids releasably engageable with the bottom. The larger container lid having a flat upper surface which is sized to hold at least two of the smaller containers, and having structures to position one, and to position two smaller containers against sliding movement on said flat upper surface such that whether one container or two containers, the smaller containers are balanced about a central axis of the larger container and lid.

    摘要: A container has features to indicate tampering and to discourage reuse as a deterrent to use with counterfeit goods. A lid hinged to a thermoformed thermoplastic base defines a product compartment. A line of weakened material surrounds a retention tab within a base upper wall. The tab is secured to a lid upper wall such as by a weld. The retention tab is secured to the lid through an opening in an enclosure element such as a card of thermoformed sheet. When the lid is separated from the base the retention tab is detached from the base along the weakened line of material and retained by the secured connection to the lid with the enclosure element retained by the retention tab to the lid upper wall. The retention tab interferes with the removal of the enclosure element from the lid and its reuse with counterfeit goods.
