  • Patent number: 9856069
    Abstract: A thermal insulation bag includes a bag body and bag bottom, the bag body includes an outer layer and inner layer, where the outer layer is welded to the bag bottom, the inner layer includes an inner side wall and inner bottom welded to the inner side wall, the inner side wall is formed by welding a one-piece material, and an upper end edge of the inner side wall is welded to the outer layer. The present invention prevents overlapping edges from appearing upon the welding of all sheets because the inner side wall of a one-piece structure is configured on the inner layer of the thermal insulation bag, allowing the thermal insulation bag to have a better appearance.

  • Patent number: 8919082
    Abstract: The present invention provides a collapsible foam shipping cooler and a process for producing the collapsible cooler. The collapsible cooler includes a linear series of attached side panel sections where each of the adjacent side panel sections are separated by a V groove formed by 45° beveled cuts made in a ends of each of the sections, and an adhesive tape flexible hinge is attached on the side of the panels opposite the V groove. The series of attached side panel sections is movable between a collapsed storage mode and an assembled mode where the series of sections are arranged to form a closed rectangular loop with top and bottom perimeter edges. Top and bottom foam panels contact the top and bottom edges of the closed loop to form a closed insulated cooler which is matingly received in a conventional corrugated box shipping container.

  • Patent number: 6851454
    Abstract: The combination of a flexible pipe, e.g. plastic, and a reinforcing member mounted around the pipe to strengthen the pipe and to enhance its ability to resist deformation under load. In one embodiment the reinforcing member includes a flexible perforated plastic netting containing an aggregation of lightweight elements such as expanded polystyrene beads capable of wrapping around the pipe, preferably in helical fashion along the length of the pipe. In another embodiment, a number of members are mounted on the pipe in longitudinally extending fashion. In all embodiments, the beads provide drainage around the pipe when it is placed in a trench and obviate the need for gravel normally used in conventional systems. In another form of the invention, a drainage system is constructed by digging a trench, placing a reinforcing aggregate member in the corners at the bottom of the trench, and setting a large diameter cylindrical pipe in the trench.

The foam and the pressure relief system in combination substantially reduce the likelihood of flareout in use; and in storage, the buildup of heat in the event of fire, such that the vessels explode and become dangerous projectiles.

  • Patent number: 5265651
    Abstract: Floating roof storage tanks are modified to include a foam surge tank, a low-pressure blower and a foam generator for generating vapor-suppressing foam during withdrawal of liquid from the storage tank and after the floating roof reaches its lowest elevation in the storage tank so that the tank space previously occupied by volatile liquid is provided with a vapor-suppressing foam blanket during liquid withdrawal and refill. The surge tank is mounted directly on the floating roof and discharges its foam through an opening in the roof into the tank storage space. During liquid refill the foam may be forced out through a vent conduit onto the roof of the tank and dissolved and recovered.

  • Patent number: 5251282
    Abstract: The external jacket structure of an electric water heater defines with the water storage tank portion thereof a hollow insulation space that horizontally circumscribes and extends across the top end of the tank. A fiberglass foam stop block member is pressed between the tank and jacket and has a cutout area through which an immersion heating element end connector is exposed to a first jacket sidewall opening normally covered by a removable access panel. A control panel mounted externally on the jacket above the first jacket sidewall opening has a bottom interior portion that downwardly overlaps a top portion of the cutout area and communicates therewith through a second jacket opening.

  • Patent number: 5221016
    Abstract: A new insulated container, includes a hollow bottle being composed of pliable resilient material, and an insulation sleeve disposed over a portion of the outer surface of the bottle and being contracted frictionally thereabout. The sleeve has a mouth portion for receiving the bottle. The sleeve is composed of a pliable resilient material and includes an outer insulation sleeve portion and an inner pliable sleeve portion having a smooth inner surface to facilitate the insertion of the bottle into the sleeve. The method includes forming the two-part sleeve, and then inserting the bottle into the sleeve by first moving them together telescopically until a portion of the bottle disposed within the sleeve. Thereafter, the axially directed bottle-contracting impacts are applied abruptly to the bottle and the sleeve at opposite ends thereof to cause them to move axially relative to one another until the bottle is free to expand outwardly within the sleeve for gripping the bottle frictionally.

  • Patent number: 5165583
    Abstract: A thermally insulating drinks carrier is formed in two halves, an upper body portion and a lower body portion. Each portion defines six cylindrical pockets arranged in two rows and six columns. A pin and recess on each body portion enables the two portions to be located and locked together. A carrying strap is threaded through bridging loops on each portion to imprison the two body portions together. The bridging loops span channels or guide slots in the sides of the body portions to act as guides for the strap. Each free end of the strap is wrapped around a wedge and wedged under a respective loop.

  • Patent number: 5104700
    Abstract: A fire protective insulating device adapted to be placed about articles to be protected from fire. The device comprises at least one layer of resilient and compressible insulative material having a plurality of compressive fastener means for mechanically compressing the insulative material to a high density, at least a portion of the fastening material being substantially less resistive to high temperature than the insulative material. A scrim means may be wrapped about the outside of the compressed insulative material for retaining the compressed insulative material. At least a portion of the scrim means is also preferably constructed of a material which is substantially less resistive to high temperature than is the insulative material. Upon contact with high temperature, the structural integrity of the fastening means is decreased allowing the compressed insulative material to mechanically expand.

  • Patent number: 5054631
    Abstract: A one-piece container for potable liquids (e.g., beverages) includes a body portion formed of a plastics material and sized to accommodate a predetermined volume of potable liquid, and a drinking straw in fluid communication with the potable liquid within the body portion. A flexible bellows member interconnects the straw to the body portion so as to allow the straw to be foldable between a stowed position (e.g., during periods of nonuse) and an erected position (e.g., during periods of use). A recess may be formed in the body portion (e.g., in a side wall and/or an upper portion thereof) so as to accommodate the drinking straw in its stowed position. Longitudinal rigidity and stability may be provided by a series of circumferentially spaced-apart ribs integrally formed on the otherwise flexible (and collapsible) body portion.

  • Patent number: 5054640
    Abstract: A protective cap for canned soft drinks and the like is disclosed. The cap comprises an outer periphery configured to receive and snap over the upper surface of a conventional soft drink beverage can. A lip guard extends axially downward from the cap to provide a sanitary drinking surface. A grate is positioned to cover the opening in the top of the can through which the beverage may be consumed. The grate is formed as an integral portion of the molded cap. A hinged cover can rotate between opened and closed positions to permit consumption of the soft drink when in the opened position and to seal the container to prevent contamination from airborne debris and small insects when in the closed position. A detent formed upon the lower surface of the cover is received between adjacent bars of the grate to latch the cover in the closed position.
