The combination of a container and a screw-type lid is improved by a tamper-evident feature comprising a locking tab on the exterior of the container having upwardly facing teeth and mating teeth on the lid, the teeth on the container and lid being arranged so as be slidable relative to one another while in mutual engagement when the lid is rotated in one direction and to lock to one another when the lid is urged to rotate in an opposite direction. The tab is tearable to terminate the locking action, thereby evidencing tampering. A catch member formed on the container is positioned to engage and cam one of several latch lugs formed on the lid, whereby to establish a locking action with that latch lug. The catch member prevents removal of the lid from the container until the engaged latch lug is pressed inwardly far enough for it to be released from the catch member, whereupon the lid may be unscrewed from the container.

A wheeled container made of plastic has a bottom end wall formed with two wheel-receiving pockets and first and second C-configured spring clips disposed on opposite sides of each pocket and projecting away from the bottom end wall. Each clip has an open portion that faces outwardly from the container. A wheel assembly is associated with each pocket. Each wheel assembly consists of a wheel and first and second axle portions that are received by the first and second spring clips respectively of a pocket, with the wheel being received by and extending out of that pocket.

A covering band (12) is pre-heated and then definitively heated in two subsequent areas (P,Z), and is subjected to primary pulling, in an area (T), where the covering band is pulled and applied to a blister band (1), and to secondary pulling in an area (R) which coincides with the pre-heating area (P). The speed of the covering band (12) is lower in the secondary pulling area (R), so as to determine a lengthening which corresponds at least to its maximum lengthening resulting from pre-heating. Cyclical detecting of reference marks (20) printed on the covering band determines temporary reducing of the covering band (12) speed in the secondary pulling point (R), so as to provoke an additional lengthening. The device includes pulling means (5,11) of the blister band (1) and covering band (12), pre-heating means (11) and heating means (13) for the covering band (12), detecting means (16), and driving means (30) acting with different speeds, controlled by the detecting means (16).

A tamper-evident closure for a container is provided. The container is formed with means at its open upper end for making a snap fit locking connection with a cover. The container has a peripheral flange with a skirt section that surrounds and is spaced radially from the container's side wall, and the cover has a depending skirt that extends down around the upper end of the container and has a free bottom edge that lies immediately adjacent to the flange. The flange has an outer surface that is flush with the adjacent portion of the outer surface of the skirt, so that essentially the flange appear to be a continuation of the skirt. As a consequence the closure formed by the cover (lid) and the container is resistant to opening by a small child. Additionally the skirt section of the flange has a tab portion that is breakable under pressure so that, once broken, it can be depressed inwardly toward the container side wall far enough to permit a person to engage the bottom edge of the skirt on the cover and thereby force the cover off of the container. The tab portion functions as a tamper evident feature, since the fact that it has been broken can be easily discerned from inspection and since the torn tab cannot be restored to its original condition.

A container assembly includes a housing having open first and second opposite ends and an open top, a drawer in the form of a tote movable into and out of the housing, said drawer having an open top end, and a cover adapted to be releasably attached to said housing in covering relation to the open top of said housing. The cover and drawer also may be adapted to permit the cover to be releasably attached to the drawer so as to cover the open top end of the drawer. Each container assembly is configured so as to permit stacking a plurality thereof, with the bottom of one housing resting on the cover of a lower container assembly.

A casserole dish and cover that cooperate to allow cooking in a vented and unvented condition as well as a controlled transition from a vented to an unvented state. The dish includes a cam ledge and the cover includes a lip that is rotatable and pivotable on the cam ledge to allow controlled venting and access to the interior of the dish.
