  • Patent number: 6427371
    Abstract: The disclosure is directed to several related forms of PICTURE FRAMES for displaying photographs or similar illustrations. More particularly, the disclosure is directed to picture frames constructed from a single flat die-cut foldable paperboard blank convertible into a three-dimensional picture frame without requiring the use of adhesive, adhesive tape, staples, clips or other fastening materials. This is accomplished by the use of rectangular paperboard panels approximately the size of the photo or other picture to be displayed, with infolding flaps on at least three edges of the panel to engage the edges of the photo to entrap the photo and hold it in place.

  • Patent number: 6302363
    Abstract: A refrigerator magnet for holding thin non-magnetic sheet material, such as paper, against a flat, smooth, magnetically attractive metallic surface, such as a refrigerator door. It comprises a one-piece rigid unitary body having a first bottom planar magnetic surface and at least one other adjoining bottom planar magnetic surface. The magnetic surfaces are joined along a common bend line at an obtuse angle. In use one of the magnetic surfaces is in contact with the metallic surface, leaving one or more paper-receiving gaps between the other magnetic surfaces(s) and the metallic surface. The bend line functions as a fulcrum whereby the body may be flipped by application of finger pressure to lift the first magnetic surface from the metallic surface and cause one of the other magnetic surfaces to clamp the paper and hold it magnetically against the metallic surface.

  • Patent number: 5206956
    Abstract: A one-piece protective face shield intended primarily for use by health care professionals to reduce the transmission of infectious diseases carried by viral and bacterial emissions from the noses and throats of afflicted patients. The protective face shield comprises a generally flat semi-rigid transparent sheet which may be bent into a semi-cylindrical face-covering shape and suspended from the bows of the frames of the eyeglasses of the user. A pair of integral bow-engaging clips are provided adjacent to the top end edges of the transparent sheet. The transparent sheet clipped to the eyeglass bows is closely spaced from the user's face and forms a barrier to the transmission of disease causing organisms.

  • Patent number: 5161712
    Abstract: A no-spring pop-up dispenser for sequential delivery of rectangular self-stick removable notes from a fan-folded pad of such notes. The dispenser comprises a flat rectangular base wall, end walls connected along one edge to one of the opposite parallel end edges of the base wall, and top walls connected to the tops of the end walls and having an open slot between spaced apart edges of the top walls. The dispenser is characterized by a pad of notes held between the end walls being forced into an upward bowed configuration. The top walls are spaced from the base wall and extend angularly inwardly and upwardly in general conformity to the top of the bowed pad of notes. Preferably the dispenser is formed from paperboard and is provided with front and back walls. Fastening tabs are provided projecting from the front and back edges of the top walls foldably connected and in engagement with respective front and back walls of the dispenser.

  • Patent number: 4948641
    Abstract: This invention relates generally to multiple-layered thermoplastic structures. More specifically, it is concerned with a hollow multiple-layered container, preferably formed by co-extruding or co-injecting a first chemically resistant and non-contaminating inner layer and a second structurally reinforcing outer layer into a blow mold, together with a third layer comprising a copolymer blend and functioning as a tie-layer to bond said first layer and said second layer. The hollow multiple-layered container is used for the storage of high purity and highly reactive chemicals.

  • Patent number: 4852185
    Abstract: A protective face shield intended primarily for use by health care professionals to reduce the transmission of infectious diseases carried by viral and bacterial emissions from the noses and throats of afflicted patients. The protective face shield comprises a generally flat crescent-shaped semi-rigid body member adapted to engage the forehead of the wearer. It includes a resilient head-engaging means to attach the body member to the wearer's head. The body member supports a depending semi-rigid face-covering transparent sheet which forms a barrier to the transmission of disease causing organisms. Vents are provided in the body member to prevent fogging of the shield.

  • Patent number: 4739877
    Abstract: A combination key ring and card holder comprised of a padded stretchable protective pouch for credit cards or similar plastic cards to which a standard key ring is attached by a tab to one end. The pouch is adapted to hold one or more standard sized credit cards or similar cards which are inserted into the pouch through a slot which is shorter than the corresponding dimension of the card. The slot must be stretched to permit entry or removal of a card. Because the slot is shorter than the card, the card is firmly and protectively retained within the pouch.

  • Patent number: 4508221
    Abstract: A tool caddy for holding a variety of small tools of varying sizes, such as drill bits, saw blades, or the like. The tool caddy is intended to be adhesively attached to an electric drill or saber saw or the like to keep the interchangeable tool elements readily at hand. The device comprises a flat sheet of flexible material having a plurality of parallel spaced apart longitudinal corrugated tool-receiving pockets on the upper surface of the base sheet. A layer of pressure-sensitive adhesive covers the bottom surface of the base sheet for attachment to a tool housing. A removable peelable cover sheet overlies the adhesive pending application to the tool housing. An elastic strap or band extends transversely over the top surface of the tool-receiving pockets to retain a chuck key, or the like.

  • Patent number: 4152002
    Abstract: A ski boot carrier which is also adapted to the carrying of skis. The carrier comprises a base runner adapted for gliding movement over ice or snow on the upper surface of which is mounted a boot bag or similar carrying case. A flexible strap or band is secured to the boot carrying case. This strap or band functions as a handle for the carrying case. It also functions as a means for securing skis which may be carried in back-to-back relation mounted on the top of the carrying case. In this manner the skis are used as a handle to guide the carrier as it is pulled over snow or ice.

  • Patent number: 4126255
    Abstract: A ski boot carrier which is also adapted to the carrying of skis. The carrier comprises a base runner adapted for gliding movement over ice or snow on the upper surface of which are mounted two parallel spaced apart support means which in turn carry a pair of parallel spaced apart side-by-side boot clamping plates. A handle is secured to the forward ends of the clamping plates. Preferably the clamping plates are disposed at an angle extending upwardly toward the forward end of the runner. Ski boots are clamped onto the carrier in the usual manner with the toe ends of the boots toward the forward end of the runner. Boots held in this manner may be carried simply by grasping the handle. Skis may be carried by placing them back-to-back between the boots with the toe ends of the skis adjacent the heels of the boots.
