A display container includes an enclosure having a container body and a lid mounted to the container body for enclosing an interior chamber of the enclosure. The lid has an integrated lens positioned over the interior chamber and a plurality of ports extending through the lid adjacent the lens. The display container further includes a slide valve assembly for selectively opening and closing the ports. The slide valve assembly includes a track fixed relative to the lid in alignment with the ports, and a slide plate slidably received in the track. The slide plate is slidable back and forth along the track between a first position in which the slide plate blocks the ports and a second position in which the ports are unblocked.

A trading card protection assembly for storing trading cards for autographing includes a plurality of card frames that each receives a trading card to facilitate the trading card to be visible through the card frames. A holding panel is provided that has a receiving slot integrated into the holding panel. A respective one of the card frames is slidable into the receiving slot to facilitate the trading card in the respective card frame to be accessible for being autographed. Additionally, the holding panel has a hole extending through the holding panel to define a grip for gripping by a user to facilitate the trading card in the respective card frame to be autographed. A box is included that has a plurality of card slots for storing the card frames in an upright orientation in the box.

One container system includes a transparent display, a projector for providing image data on the display, and a floor defining part of a watertight cavity. The display is non-perpendicularly angled from horizontal and has proximal and distal ends. And a closure device is provided for use with a watertight container. The closure device is configured to selectively seal an opening in the watertight container and includes coupling structure (a plug, a flange, and/or threading) for selectively coupling the closure device to the watertight container to seal the opening. The closure device further includes non-transitory computer memory, at least one sensor, and a processor in data communication with the memory and the at least one sensor.

A method of injection molding a test tube-shaped preform for biaxial stretch blow molding includes supplying a major material resin from outer and inner flow paths to a combined flow path for a predetermined time and rate. For a period of time within a range of the predetermined time period during which the major material resin is supplied, the intermediate layer resin is simultaneously supplied from the middle flow path to the combined flow path at a second predetermined supplying rate. A columnar laminated molten resin is injected into a cavity of a metal mold connected to a tip of the nozzle through a gate to fill the cavity, the columnar laminated molten resin being composed of the major material resin and the intermediate layer resin formed in the major material resin in a laminated manner that are combined into a columnar shape at the combined flow path.

A flexible and inflatable tank for the supply of potable water that is made of a strong, rigid and flexible material and is designed to incorporate a thin, flexible inner bag that is made of materials that comply with standards for the storage of potable water. The tank is made of a rectangular sheet, a pair of walls, and one or more openings and is shaped in general like a closed, round, oblate cylinder with two side walls.

To solve a problem associated with formation of a transparent window portion in a biaxially stretch blow molded container by a nozzle structure of an injection molding apparatus, provided is a biaxially stretch blow molded container formed with a clearly transparent window portion in longitudinal strip shape by effectively preventing mixture of colored resin to window portion. Injection molding apparatus includes in nozzle portion a longitudinal groove flow path, wherein a transparent B resin flows. By, for example, reducing and increasing, respectively, the width and depth of the longitudinal groove flow path on the downstream side, and engraving slits in an inner mandrel and even in a front end portion of a stopper pin, flowability of the B resin in a horizontal direction is enhanced.
