    Abstract: A hygienic device for use with a container opening is provided. The hygienic device includes a base and at least two guard elements which are integrally formed as a unitary structure. The guard elements, which are made of a soft resilient material and positioned on the base, are readily bendable downward to change shape and thus facilitate the opening/closing thereof, and can get closer together to form a protective layer for enclosing the container opening. The hygienic device requires lesser constituent elements and dispenses with the need to remove a hygienic lid from the container before using the container. The guard elements are capable of rebounding and adjusting shape and thickness, effective in balancing a resilient force and a binding force generated as a result of the bending and opening of the guard elements, and effective in attaching to the container; hence, the guard elements open without increasing occupied space.

The outer surface of the enclosure includes a curved region surrounding the opening; the curved region having a radius. The enclosure includes a resilient cover which is hingedly secured to the enclosure for selectively covering the opening. The resilient cover moves between a first open position and a second closed position. The resilient cover is molded to normally have a first radius which is greater than the radius of the curved region of the enclosure. When in the first open position, the resilient cover defines an arch having the first radius. When in the second closed position, the resilient cover is compressed and flexes so as to conform to the shape of the curved region of the enclosure. Thus, in the second closed position, the resilient cover defines an arch having a second radius which is smaller than the first radius.

The operator portion has a normal position whereat the truncated pyramid extends longitudinally away from the bumper opening and a reverse truncated pyramid position to cause said side sections to be bowed transversely outwardly and thereby substantially increase the force of engagement between the outer surfaces of said side sections and the four inside surfaces of the bumper to thereby lock the plug to the bumper.

  • Patent number: 4958744
    Abstract: A closure for the open mouth of a container includes a main body and sealing means which extends around the periphery of the main body. The sealing means has a sealing edge which is adapted to engage a sealing surface formed on the container, and a resiliently flexible web which connects the sealing edge to the main body. The web is movable between a relaxed condition, in which the diameter of the sealing edge is at a maximum, and a sealing condition, in which the diameter of the sealing edge is less than maximum. When the closure operatively closes the opening in the container the web is moved to the sealing condition, and the resilience of the web material serves to press the sealing edge against the sealing surface. Preferably the web in its relaxed condition has a frusto-conical form which diverges upwardly and the sealing edge is formed on the upper and outer edge of the web.

  • Patent number: 4819862
    Abstract: A foldable, resilient plate lid of paperboard or the like, having a central panel surrounded by four side panels glued together at overlapping end flap portions to form a continuous skirt which, when open, flares obliquely downwardly from the central panel to encompass the rim of a disposable plate. Opposed rim-receiving slots are formed in at least tow of the side panels. Initially, for gluing, the latter two side panels are folded inwardly under the central panel while the other two panels remain unfolded except for their end flaps, so that upon subsequent opening of the skirt to cover a plate, resilient bias forces urge the initially folded side panels into secure engagement with the rim.

  • Patent number: 4777933
    Abstract: An access door construction for a gas-fired water heater. The lower end of the outer jacket of the water heater is formed with an access opening and a door or panel bears against the outer surface of the jacket and encloses the opening. Tabs are formed on opposite side edges of the panel and engage the inner surface of the jacket adjacent the opening. In it unassembled condition, the panel is flat and when assembled with the cylindrical jacket, the resiliency of the panel will urge the tabs into tight engagement with the inner surface of the jacket. The panel is formed with a vertical channel having a generally semi-cylindrical cross section. By manually squeezing the sides of the channel together, the distance between the tabs will be decreased to thereby enable the panel to be removed and installed with the jacket.

  • Patent number: 4750669
    Abstract: A container is described, of a type which includes a resilient cover whose rearward portion is heat sealed to the flange of a container bottom or body and whose front can be bent up to gain access to the recess in the body. The cover is cut from a previously rolled sheet which is arched, and the convex side of the sheet faces upwardly so the front of the container cover tends to stay closed. The cover is heat sealed to opposite side flanges at locations lying forward of the rear of the recess by at least 25% of the length of the recess, to thereby more firmly keep the cover closed. The front of the cover and body are formed with aligned holes forward of the recess, so the container can be stored on a rod without the contents spilling out.

  • Patent number: 4702388
    Abstract: A sheet metal plug for holes in sheet metal boxes, such as conduit holes in electrical junction boxes, includes a circular plug disc having a groove formed along a chord thereon. The plug disc is bent along the groove such that a portion of the disc is angularly displaced from the plane of the remainder thereof. A number of tabs, carried on the undersurface of the disc, are arranged to engage the edge of the hole when the plug is inserted into the hole. One of the tabs is positioned on the angularly displaced portion of the disc such that the disc is initially insertable into the hole, after which the displaced portion is straightened to bring each tab into secure engagement with the sheet metal which is being plugged. The thickness of the disc is substantially reduced along at least a portion of the groove such that its resistance to bending is substantially reduced therealong. A land or area of increased thickness bridges the groove to strengthen the disc at the groove.

  • Patent number: 4685586
    Abstract: A door system for a boiler penthouse or other high temperature industrial environment is disclosed. A sufficiently large entranceway for both workmen and large equipment is provided by the door system. The access door has the capability for quick gas-tight sealing during closing. A hinged metal door plate has arcuate welding beads applied to its internal surface near its corners to produce permanent inward cupping of the door plate adjacent to its corners. Devices apply pressure to the exterior surface of the door plate during the closing thereof to flatten the inwardly cupped corners and effect gas-tight sealing of the interior surface of the door plate near its margin with an opposing high temperature resistant gasket carried by the front face of a refractory insulated door frame. A layer of thermal insulating material in a protective jacket is secured to the interior surface of the door plate.

  • Patent number: 4520944
    Abstract: A closure for an open-ended container such as a tray wherein the closure element is easily inserted into the tray so as to retain the tray contents but is quickly removed therefrom to facilitate dispensing of the container contents. The container walls are formed with slots which open to the outside of the container as well as extend transversely through the walls. A locking element in the form of an elongated strip of material is inserted into the slots from the outside of the container and is retained therein in a manner such that removal without bending the strip material is substantially impeded. To remove the locking strip member from the slot, all that is required is a pulling action transversely to the container walls which will permit its withdrawal and opening of the tray-like container for dispensing of its contents.
