Abstract: This invention relates to cover panels for enclosures, such as those found on the sides or roofs of buildings, which house air conditioning equipment. More particularly, this invention relates to a cover panel for an air conditioning enclosure which both accommodates the penetration of piping through it and allows for access to the interior of the enclosure, subsequent to the hookup of the piping to air conditioning system components housed within the enclosure, without the need to break a piping connection.

Abstract: The invention relates to the combination of a closure and of a container, the closure displaying a peripheral depending skirt while the container displays, along the walls thereof, a continuous peripheral flange receiving, on the top face thereof, the lower edge of the closure skirt. The connection of the flange at each corner is weakened by the presence of a series of gaps to render the flange at those areas breakable to thereby provide a visual indication of removal of the closure, whether it be authorized or unauthorized.

Abstract: A plastic pail (23) and a plastic lid (22) are constructed at their rims so that the lid securely seals and catches in. Pockets to receive a carrying handle are part of a cylindrical ring (28) which surrounds the pail wall concentrically. This ring is drawn down arcuately at two diametrically opposite points (25), so that it is possible to grip and remove the lid (23) there, and a circular alignment of pails stacked nested without lids is simultaneously possible by this means.In a particular construction the recesses formed by the arcuately down-drawn parts of the ring are covered by tear-off bridges (40) which are fastened to the ring radially outside the latter.

Abstract: A breakout panel (6) is situated within a breakout opening (8) in a molded part (2). The breakout panel and opening define circumferentially extending corners (16, 18) positioned adjacent one another. The two corners touch at a line of intersection (21) having substantially no width to create a zero landed intersecting edge. Physical connection between the breakout panel and the body is provided by several small frangible pads (22) at the line of intersection. The frangible pads are sized to permit the breakout panel to be broken away from the body in a frangible manner to expose the breakout opening. The frangible pad intersects the body along the inside surface (20) of the body so that when the breakout panel is broken away, the resulting scars (38) at the locations of the frangible pads are not visible from the outside of the part.

Abstract: A method and apparatus are disclosed for the fabrication of an openable container lid wherein a failure zone opening is defined about the desired location of a future opening in the lid, and simultaneously with this operation the lid is joined to the flange of the container. The combination of both of these steps at a single work station minimizes the equipment necessary to attach a lid to a container.

Abstract: A tamper-evident lid for use with containers includes a surface to cover the container, and downward projections around the periphery of the surface which surrounds the mouth of said container. An interrupted ring is frangibly attached to the downward projections. A plurality of tamper-evident hooks are affixed to said ring. The hooks are visible through openings in the downward projections. The hooks engage the container, but when the lid is removed, the ring fractures away from the downward projection ring and the tampering with the package is apparent. In the preferred embodiment, a bead on the lid engages the sidewall of the container to provide a resealable, airtight seal.

Abstract: A container lid can be used for open-mouthed containers having a peripheral curl about the rim of the container. This peripheral curl defines a rim receiving cavity which may be snap fit over the rim of the container to attach the lid to the container. The container may thereafter be effectively closed by the lid. This lid may additionally have a well having an upwardly sloped portion and a well portion. The well portion has a raised element therein, which can form openings in the lid. In particular, by applying a downward force to a top surface of the raised element, eye-shaped slits may be formed at frangible areas adjacent the corners of this element. These eye-shaped slits permit contents within the container to be discharged therethrough. For instance, a beverage may be held in the container. After applying a downward force to the raised element to form slits in the container lid, the beverage may be discharged through the slits, passed over the sloped portion and then poured and/or ingested therefrom.

Abstract: A molded plastic electrical outlet box having improvements relating to a plurality of webs for attaching a cable entry aperture knockout panel to the box wall structure defining a given aperture, a strip of flashing connected about the knockout panel, and a pattern of protrusions defined on the exterior face of each knockout panel. The attachment webs are located in a four point, balanced arrangement adjacent to the respective corners of the generally rectangular panel. Thus, any knockout force applied to the panel by the tip of an instrument, such as a screwdriver, will always be directed between the locations where the panel is anchored to the wall structure and tend to result in detachment of the panel. The protrusions can take any one of a variety of patterns, such as a knurled pattern or a multiplicity of cylindrical-, pyramidal- or tetrahedral-shaped projections, to define non-skid surfaces which prevent the tip of the instrument delivering the knockout force from slipping upon impact with the panel.

Abstract: A lidded container is provided which is intended to deter unauthorized removal of the lid. The container has an out-turned lip of inverted U-section having a circumferential horizontal flange supporting an upright retention portion with a retaining bead.
