Semiconductor wafer cassette transport box

150 mm wafer cassette for use on 200 mm semi standard wafer handling

An enclosed semiconductor wafer holder, and a cover providing isolation control of semiconductor wafers that is simple, lower cost, and non-obtrusive is described. The device includes a cover with a sealing perimeter that creates a hermetic seal when engaged with the semiconductor wafer holder. It also includes a purging means attached to the holder that allows an active gentle purging of inert gas into the sealed semiconductor wafer holder. The holder has contoured recess-forming pairs that do not effect semiconductor wafer transfer when the recess forming pairs are warped. The recess-forming pairs also have integrally corresponding ribs that help prevent warpage of the contoured recess-forming pairs during the plastic injection molding process.

A semi-conductor transport container is described, which includes a box, a door and an actuated rotary retainer attached to the sidewall of the box to thereby prevent movement of the wafers within a wafer cassette during transportation and storage. The rotary retainer includes flexible fingers that apply a slight force against the wafers when the box is engaged with the box. The rotary retainer is simple, requires less moving parts, and rotates automatically, completely away from the wafers when the box is disengaged from the door. Also, the box seals with the door, when engaged with a door, thereby creating a particle free storage area.

This is an improved container having slidable storage cases propelled by a leaf spring into an open position after pushing down on a front catch. The container comprises a front half, a rear half and a handle, each molded from plastic. The front half and the rear half of the container are ultrasonically bonded together rotatably securing the handle between them. The front and the rear half have six case slots. The front half case slots are defined by a central vertical divider extending from the top to the bottom of the front half and three rows of horizontal M-shaped plastic dividers. Each M-shaped divider is essentially a spring with a lip on it at the central point of the M-shaped divider. The lip can be pushed down and snaps back into place. The rear half is divided into six case slots by a central vertical divider extending from the top to the bottom of the rear half and six sets of guide rails. Extending into the rear half from the back of the container are six leaf springs, one for each case slot. A case is inserted into a case slot over the lip of the M-shaped divider and between the guide rails in the rear half. The rear end of the case pushes against the leaf spring causing the leaf spring to coil or become tense and push against the rear of the case. The front lip catches the front end of the case and holds the case in a closed position. To pop the case out of the container, the front lip is pushed down, the leaf spring releases pent-up tension and the case is propelled out of the container into an open position.

Tackle tote

A spill inhibiting funnel system is described that has stepped fins and blades extending, respectively, from the outer and inner surfaces of a tapered funnel body. The fins allow the funnel to be variably positioned with respect to a receiving container's opening in a secure fashion to prevent spills. Likewise, the stepped blades allow a pouring container to be securely placed inside the funnel and remain there in an inverted upright or angled position.

A hard clear hangable package, locking cover and key for use in retail merchandising of video games and the like to further reduce the amount of business losses attributable to theft. The device includes a locking cover with an outer lip that prevents opening of the container without the precise key. It also includes a clamping member attached to a key base that automatically rotates into engaging position allowing the box to be removed from the locking cover, permitting the contents of the security box to be removed. The device firmly contains video games or the like.

Security package

A device for opening security packages used to protect audio-visual media from being stolen is disclosed. The security package opening device includes a base which assists with proper positioning of the security package to be opened. It also includes a slidable opening mechanism which, when slid forward, automatically causes key elements to enter the locking means of the security package. The opening mechanism then opens the security package permitting the contents of the security package to be removed.

Opener for security package with spring loaded keying mechanism

A security package having a slidable locking structure to retain a CD, cassette or the like in the security package. The slidable locking structure has a stationary surface which contains a T-shaped protrusions each having a lever arm. A slide plate contains recesses for receiving each end of the lever arm, apertures adjacent to these recesses and a lip along an edge. The security package is locked when the slide plate is slid to engage the lever arms into the recesses allowing the lip to extend over the holding structure to retain the CD, cassette or the like. A key which mates with the apertures is used to apply a simultaneous uniform force to release the lever arms from the recesses.

Can crusher

A can crusher for compacting cans, such as aluminum soft drink cans, into a substantially flat configuration for storage, recycling or disposal. The can crusher includes a base with opposing flanges and a handle which rotates about the flanges. The handle includes an extending crimping member which compresses the center of the can downwardly, and also forces the ends of the can inwardly. The handle also includes a flat surface which then flattens and rotates the ends of the can towards a mid-portion of the can into a substantially flat configuration. The first action of the extending crimping member against the can and the second action of the flat surface against the can crush the can into a substantially flat can which is environmentally and ecologically useful in recycling processes. The crushed can consumes less space in recycling operations or disposal, and environmentally and ecologically presents itself in a more pleasing manner for recycling or disposal.
