Abstract: Based on the embodiment structure shape and vertical position installation of 12/18VCT tray there are very remarkable advantages for supporting more cables, copper conductor savings and perfect application for retrofit and new projects, compared to traditional, ladder or ventilated, 12/18HCT tray, as described under CLAIMS section. 12/18VCT tray has improved embodiment structure shape and has been described for a preferred embodiment design of invention, compared to 12/18HCT tray. It will be understood that the design is capable of further modifications therefore, 12/18VCT tray is intended for comparison to any variations, uses or adaptations, following the principle of heat transfer theory, Newton's Law of Cooling Formula and N.E.C., Chapters 310 and 392, for cables and cable trays. The invention includes all parts from the disclosures, as come within known or customary practice, in the art to which invention pertains and falls, within the limits of the appended claims.

Abstract: The principal of present invention is the creation of a flat vertical divider inside of the traditional bottles and jars by a simple additional molding steps to the traditional molding process technology creating two equal separated useful compartments. The common materials to manufacture bottles and jars are plastic and glass but any material which could be molded can be used. New improvements and conveniences of present invention for people are as follows: Two liquids of the same or different types could be stored in only one bottle or jar. Useful mixtures from two different liquids could be obtained. In case of an accidental puncture of one compartment, half of liquid remains in the other compartment. Less bottles and jars are carried by traveling persons. Additional free storage space would be created. Less bottles and jar for disposal.
