Abstract: There is provided a nurser liner that facilitates stacking and nesting of the liner while maximizing liner capacity. In particular, it permits a plurality of the liners to be contained within a container having limited internal space while allowing the liners to de-nest properly and individually from the container. The nurser liner includes a rim that is located at one end of the liner and a step that is located a predetermined distance from the rim. In addition, the outer walls of the liner are slightly tapered inward from the rim. The step and the tapered outer walls insure uniform spacings between nested liners for easy dispensing, optimal spacing between liners and maximum liner capacity.

The ledges and ribs positioned and configured relative to one another such that when the tray is nested a distance down into a similar empty tray the rib rests on the corresponding shelf or ledge of the similar empty tray, so that the load of nested trays is transmitted vertically downward and fraying of the tray wall structure is prevented.

Abstract: A bundle-of-electric wire container can contain a bundle of electric wire P wound in a loop shape and permit drawing out of the electric wire. Containers can be stacked in a plurality of stages to increase storage efficiency and conveyance efficiency. A bundle-of-electric wire containing space is formed between core pieces and an outer cylinder, and the bundle of electric wire is protected by the outer cylinder. The container is used as one unit for the storage of a bundle of electric wire and to the feeding of the electric wire P through a conveyance. Accordingly, in the manufacturing field of a wiring harness, the bundle of electric wire can be stored and conveyed without losing its shape, for example, and done so efficiently. It is possible to improve the operating efficiency of a manufacturing line by preventing the electric wire from being tangled, for example, at the time of feeding the electric wire as well as to prevent an inferior product from being manufactured.

Abstract: A dual purpose low depth nestable tray for holding either cans or bottles of similar capacities with structural features that prevent spreading or fraying of the walls. The tray comprises a floor, a band around the periphery of the tray and columns interconnecting the band to the floor. A nesting nub is disposed on the floor and nesting ledges are disposed on at least one column along each side of the wall structure. The nub and ledges are equal in height and act as supports for the weight of a stack of nested empty trays which prevents the walls from having to support the weight and results in the walls maintaining their shape and structural integrity. The floor is configured with support areas for the containers and has features for accommodating both bottles and cans. The support areas have a circular groove for engaging the bottoms of cans and the bottom surface of the floor has downwardly projecting redoubts for facilitating stacking and handling of trays loaded with cans.

This orifice is adapted to receive a beverage vessel. There is a second orifice through the top of the base which is circular in shape located at the opposite end of the tray from the first orifice. The second orifice is adapted to receive a food plate. There is a first notch located at the front of the base, adapted to receive an area between a thumb and a first finger when being held with the thumb on top and fingers on the bottom of the base. There is another notch located to the back of the base, adapted to receive an area between a thumb and a first finger when being held with the thumb on top and fingers on the bottom of the base. In a preferred embodiment, the second orifice has a surrounding recess tapered to receive an outer rim of a plate.

Abstract: A pail assembly including a plastic pail and a plastic lid which can be snap fit sealed to the top of the pail. To reduce excessive outward doming of the lid and the pail floor caused by internal pail pressures, due for example to chemical reactions of hazardous material contents, rib structures are formed on and extend across the interior surfaces of both the floor and the lid. To prevent this doming the floor is also formed to be bowed upwardly at its center with a small curvature radius. A large radius connection of the floor to the pail sidewall better distributes impact stresses. A locating ring channel is formed on the lid surface and is dimensioned to receive therein the feet of two different size pails when the pails are loaded and stacked. Ribs on the outside and inside of the channel resist the tipping of the pails of either size when alternatively stacked thereon.

Abstract: A circumferential rib-stiffened hollow cylinder and method for fabrication thereof featuring construction of the cylinder from complementarily shaped nestled prefabricated rings and resultant circumferential ribs which are integral with the rest of the cylinder. In one embodiment ring sections which are "L"-shaped in cross-section are axially and sequentially mated; ring sections which are "U"-shaped are axially and correspondingly integrated therewith, therein for a cylinder having internal circumferential ribs and thereout for a cylinder having external circumferential ribs. The dominant load path for the cylinder is through the reinforced cylinder elements, and the cylinder's wall-thickness-to-diameter ratio is effectively reduced, thereby allowing radial reinforcement of the ribs, reducing residual stresses and increasing strength; these advantages are especially significant for cylinders which are composite or are to be subjected to hydrostatic pressure.

Abstract: An article of manufacture comprising an integrally molded plastic cup nestable with indentically formed plastic cups. The mouth of the cup is formed with a threaded portion and a circumferential lip portion therebeneath. The threaded portion may be matingly engaged with a threaded cap, or if desired, the threaded portion may be removed and the lip portion may be matingly engaged with a snap-on cap. Thus a cup with two alternative types of closure means may be manufactured from a single mold and a single inventory can be kept for orders of either type of closure. Air passage means are formed in a surface of the cup wall to permit air to flow therethrough when identical cups are nested thereby preventing difficulty in removing one cup from another due to air pressure differentials inside the nested cups created during storage temperature differentials and during separation of nested cups.
