Abstract: An agricultural container or fruit bin made of plastic has four vertical walls, triangular corner columns and a bottom element. The exteriors of the vertical walls and bottom element have rectangular rib patterns. Openings in the vertical walls and bottom allow for atmospheric circulation. The upper edges of the sides are bowed inward slightly, and the bottom element has a slight inward dome when the bin is empty.

Abstract: A Plastic fruit bin having four vertical walls and a bottom joined to the walls. Two supporting elements extending along and attached to the bottom elements. An array of gas injection tubes disposed on the lower side of the bottom element and extending up the center of each of the vertical walls. The vertical walls are joined to each other at their sides by a triangular shaped column, each of said columns forming a corner of the bin, and the columns being stiffened internally with longitudinal ribs. A rectangular recess at the bottom of each corner, the depth of the recess rising to the level of the bottom element of the bin, the recess being partially closed by a triangular shelf having its apex at the inner corner of the rectangle, and being defined by two corners of the rectangle adjacent to the inner corner, with the edge of the shelf which extends between the two corners of the rectangle defining the lower end of a triangular passageway.

Abstract: A container constituted of a microwave transparent material for the heating or cooking of foods or comestibles through the intermediary of microwaves at a high degree of efficiency and with an enhanced temperature uniformity.

Abstract: A bottle has a high strength against pressure-reduction without reducing the internal content. The bottle is made up of a circular bottom; a barrel portion extending upwardly from the outer peripheral edge of the bottom portion; and a plurality of recessed portions each having a longitudinal and approximately rectangular shape, which are spaced from each other along the circumferential direction of the barrel portion. Each of the recessed portions includes a recessed panel surface fallen in from the barrel portion by a specified stepped dimension and two pieces of swelling bodies that swell in the outer peripheral direction from the recessed panel surface by a specified height. Two of the swelling bodies, each being formed into a trapezoidal shape having a flat upper end surface, are longitudinally spaced from each other along the longitudinal length of the bottle.

Abstract: A beverage can that is capable of crushing easily in the axial direction is provided. The beverage can is designed to contain a beverage and has a roughly circular cylindrical shape with, at a prescribed portion on one end surface thereof, an operational portion for forming a beverage-input port. A side wall of the can has a bellows-like structure provided with score lines.

Abstract: The meter box has an inside wall defining a cavity and having upper and lower ends, with upper and lower openings respectively leading to the cavity whereby the cavity may receive a meter by way of the lower opening. An outside wall having upper and lower ends is spaced from and surrounds the inside wall. A receptacle wall is coupled between the upper ends of the inside and outside walls for receiving and supporting a cover. A flange is coupled to and surrounds the outside wall between the upper and lower ends of the outside wall. The flange has an upper flange wall coupled to the outside wall and a lower flange wall spaced from the upper flange wall. The outside wall has alternate inner and outer wall sections spaced from each other and having upper and intermediate ends respectively. The lower flange wall is coupled to the intermediate ends of the outside wall sections of the outside wall.

Abstract: A hollow stackable product including at least a section of a generally conically contoured sidewall having a number of longitudinal folds of alternating ridges and furrows. Each fold includes a first side strip laterally extending from the top of a ridge to the bottom of an adjacent furrow and a second side strip laterally extending from the bottom of the furrow to the top of the next adjacent ridge. The first side strip has a different lateral orientation than the second side strip. The first side strip has a greater wall thickness than the second side strip; and the first side strip also has a shorter lateral extent than the second side strip. When the product is stacked within a like product, a first product is placed inside a second like product so that the first side strips of the first product are positioned closely adjacent the first side strips of the second product and the second side strips of the first product are positioned closely adjacent the second side strips of the second product.

Abstract: A vacuum panel design for a hot-fill container which resists the increase in container diameter (barreling) which may occur during hot-filling and/or when the container is dropped on a hard surface. In one embodiment, adapted for a full wrap (360.degree.) label, a plurality of vacuum panels are symmetrically disposed about a vertical centerline of the container and horizontal stiffening ribs are provided across select portions of the panel, namely, across the vacuum panel recesses and across the post and panel ribs. In another embodiment, adapted for spot labeling, a pair of vacuum panel regions are symmetrically disposed about a vertical plane passing through the vertical centerline of the container, which regions form spot label areas and are joined by connecting end segments. The angular extent of the spot label areas and end segments may be varied to adjust the resistance to barreling and/or to provide a squeezable container, and horizontal stiffening ribs may further be provided to decrease barreling.

Abstract: A high pressure plastic container is made by rotationally moulding a first wall of plastic material, and a second wall enclosing and bonded to the first wall. One of the walls is integrally formed with a plurality of circumferentially-extending axially-spaced ribs of a hollow construction. The other wall may be unribbed, or may be integrally formed with a plurality of axially-extending circumferentially-spaced hollow ribs. The hollow ribs, are filled with a rigid plastic foam.

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.

Abstract: A preform injection molded from PET includes a frustoconical section whose outer surface is formed with a series of angularly spaced ribs. When the preform is converted into a bottle by a blow molding operation, the frustoconical section of the preform is converted to a frustoconical top breast for the bottle while the external ribs of the preform are converted into internal ribs which are spaced angularly around the inner side of the top breast to increase the column strength thereof.

Abstract: A device for protecting a carbon disk stack used in an aircraft brake assembly is disclosed. The glove-like device is constructed of an impact-resistant, flexible material and is installed by sliding the device over the carbon disk assembly. The device may be used to ship a carbon disk stack fixed to a torque tube of the brake assembly or to ship a stack of carbon disks alone.

Abstract: A blow molded bottle comprising oblong depressions in opposed major sides of the bottle, the bottom of the oblong depressions being joined at the center of the bottle. Extending from the major axes ends of the oblong depressions is a single depressed rib circumferentially extending about the bottle. The joined oblong depressions and circumferential rib substantially increase the rigidity of the major sides of the bottle allowing a substantial decrease in bottle wall thickness and attendant material weight.
