Abstract: A container including a storage chamber within which is located at least one concentrated product housed; a mixing chamber coupled to the storage chamber; and a closure element, wherein the storage chamber is isolated from the mixing chamber; the mixing chamber is defined by a body having a longitudinal length defined between opposed ends and along at least a portion of the length of the mixing chamber, the body defines circular bellows, such that the mixing chamber has a collapsed configuration when the ends of the body are urged together and an expanded configuration when the ends of the body are urged apart, the bellows further including a latching arrangement which acts to latch the bellows in their collapsed configuration and/or their expanded configuration; and wherein a first end of the mixing chamber is open and is selectively closable via the closure element.

Abstract: The device system of the invention while in use is designed to include one stationary tray assembly with a plurality of non adjacent compartments for holding a first set of DVD cases or alike, spaced apart by a plurality of slidable carriers adapted to fit within the remaining compartments, for holding a second set of DVD cases. The slidable parallel carriers are joined at the front or the rear side of the storage system to act as a single slidable assembly including a frontal handle that allows for push-pull operations. The individual carriers and respective DVD cases carried by the sidable assembly are adapted to slidably engage in every other compartment within the separation walls of the stationary tray, while the remaining compartments of the stationary tray are adapted to hold stationary DVD cases.

Abstract: In one embodiment, a rack assembly for storing digital media comprising a plurality of parallel U-shaped channels comprising substantially vertical side walls for supporting the weight of a computer monitor or alike, and whereas the spacing between the vertical side walls of each channel is adapted for receiving CD or DVD cases. The rack assembly may include a slidable platform for supporting a monitor, and support means for holding the rack assembly above the desktop surface for inserting a computer keyboard. In another embodiment, the rack assembly includes a slidable keyboard tray mounted along the supporting lateral side walls for moving the keyboard tray between a work position and a storage position located directly under the rack assembly.

Abstract: A device for storing and displaying a plurality of DVD cases and the like comprising a plurality of parallel rigid L-shaped profiles pivotably connected, characterized in that the convex side of each L-shaped profile includes at least one adhesive layer to fixedly attach at least one DVD case by the spine side or by its adjacent back side area, hence allowing the front covers of the case to pivot freely.

Abstract: A writing instrument holder may be constructed from a sheet of corrugated plastic, that is cut to the desired configuration and glued, riveted, stitched, or otherwise attached to a mounting surface. The corrugated plastic forms a series of open tubular cells. A selected tubular cell receives the clip of a pen, pencil, or other writing instrument, while the writing instrument hangs by the clip on the outside of the holder.

Abstract: The invention provides an improved pen holder in the form of a piece of corrugated plastic sheet, that can be cut to the desired size and glued to any flat surface. The clip of a pen penetrates the inside of a tubular chamber while the pen hangs on the outside.

Abstract: A computer desk which comprises an upper shelf for receiving a computer monitor, a desktop shelf for receiving the keyboard, and means for converting the desk into a seat by rotating the desktop shelf assembly.

Abstract: A closure or cap for containers, bottles and jars having a circumferential groove formed by opposed conical surfaces of substantially equal size in the relaxed condition and upon compression of the closure forming a substantially toroidal circumferential groove. On a container sealed with the closure compressed, expansion of the circumferential groove to the relaxed condition indicates failure of the seal or generation of gases within the container. In an alternate embodiment the circumferential conical surfaces form a V-shaped circumferential protrusion in the relaxed condition and a toroidal protrusion in the compressed condition. In another embodiment the circumferential juncture between the conical surfaces and the closure sidewall is modified to reduce the flexure between the compressed and expanded conditions thereby permitting a wider variety of materials to be used for the closures.

Abstract: Hollow articles such as plastic bottles and tubes having a portion of the sidewall including latching bellows, are formed with modified inner and outer fold rings to reduce the angular flexure between unfolded and folded (latched) bellow walls. The bellow walls are modified by reducing the slope of the walls as they approach the inner fold rings to thereby reduce the unfolded (unflexed) angle between the walls at the inner fold rings. The modified geometry permits better utilization of high density linear polymer plastics by lessening or preventing the "crystalline" fracturing and lamination at the inner fold ring with the first latching of the bellows. The bottle material is therefore no longer weakened at the inner fold ring. The modified geometry also permits use of low density polymer plastics and rubber for latching bellows with thicknesses and geometries that otherwise would tend to eventually spring back rather than latch.

Abstract: A collapsible or foldable plastic bottle of circular bellows like configuration capable of manufacture on current plastic bottle manufacturing equipment with current plastic materials approved for contact with foods and beverages. The bellows over center and fold to retain the folded condition without external assistance thus providing a self-latching feature. In particular, the bellows of the bottle, when fully folded, cause the bottle to substantially fit within a cup fastened to the base of the bottle. The cup is generally formed by further extending the cup upward and increasing the diameter slightly in comparison with the reinforcing cup on current soda pop bottles.
