Abstract: A container and method of manufacture are provided. The container includes a cup with a permanently attached sleeve overlying an exterior portion of the cup sidewall. The sleeve includes a plurality of inwardly directed protuberances providing a gap between a substantial portion of the cup sidewall and the sleeve.

Abstract: A laminated end disk construction for food sauce dispensing cartridges and other food containers. A laminated end disk through which food sauce may be dispensed is provided with a valve layer and a support layer. The valve layer includes a plurality of valves, and the support layer includes one or more openings and a kiss cut defining an outer perimeter area and an inner area. A protective patch may be removably attached to the support layer along at least a portion of the outer perimeter. The invention also provides a laminated end disk wherein the ratio of the support area to the dispensing area is less than about 7.

Abstract: A tamper evident package for dairy products and other foods and consumables. A conventional container and lid are included, along with a plastic disk which is wedged in place on top of the lid with the edge of the disk fitting in a channel in order to prevent removal of the lid. The disk has a frangible center section which must be broken away before the disk can be removed to release the lid. The presence of the disk intact on the lid indicates that the container has not been opened, while absence or mutilation of the disk provides visible evidence of tampering.

Abstract: A disposable container for cigarettes, cigars, cigarillos and similar articles. The container includes a generally cylindrical tubular body having an inwardly rolled lower rim at the lower end thereof engaging a generally circular bottom closure disc sealed within the body in abutment with the lower rim. The bottom closure disc is formed of relatively thin resilient sheet material such as thermoplastic synthetic resin material. One embodiment of the bottom closure is configured in the shape of at least two concentric, interconnected, frustroconical portions so that the bottom closure is bistable in a first position extending generally across the tubular body and alternately, in a second position extending upwardly into the tubular body thus displacing at least a portion of the contents upwardly out of the over upper end of the container.

Abstract: A disposable container comprising a filled, temporarily sealed cartridge for use in a caulking gun-like dispenser mechanism for repeated discharge of incremental amounts of the contents thereof of mayonnaise-like consistency. The cartridge includes a generally cylindrical tubular body having an inwardly rolled rim at one end thereof with a generally circular disc sealed within the body in abutment with the rim. A plurality of mutually intersecting slits through the disc form a resilient, pressure-responsive valve and orifice in the center portion of the disc.

Abstract: A disposable container comprising a filled, temporarily sealed cartridge for use in a caulking gun-like apparatus for repeated discharge of incremental amounts of the contents thereof of mayonnaise-like consistency. The cartridge includes a generally cylindrical tubular body having an inwardly rolled rim at one end thereof with a generally circular disc disposed within the body and adhesively sealed in abutment with the rim. A plurality of mutually intersecting slits through the disc form a resilient, pressure-responsive valve and orifice in the center portion of the disc. A plug top closure is at least partially disposed in the open opposite end of the tubular body and is provided with a cylindrical sidewall sized to be closely received within the tubular body, at least one circumferential rib on the cylindrical sidewall for tightly and slidingly engaging the tubular body, and a radially outwardly extending closure flange for yieldably abuttingly engaging the annular end face of the tubular body.

Abstract: A convolute sidewall container of paperboard or the like having an outwardly rolled top rim and a closed bottom, the container comprising a one-piece sidewall blank of generally rectangular shape having top and bottom edges, first and second side edges, and four corner edges. The four corner edges are so configured as to facilitate production blanking operations and the formation of the outwardly rolled top rim without bulges, splits, tails or torn places in and around the overlapped portion of the rolled top rim.

Abstract: A closure having at least two layers adapted to be fixed to the end of a container to close the same the inner layer of the closure being scored on its inside as well as its outside surface in a manner to permit rupturing of the layer between the score lines when a force acts upon the outer layer to form a shouldered removed closure portion receiving ledge with which the removed portion will mate upon reclosing the container. In an embodiment, enclosure is crimped to the end of the container. In another embodiment there is provided between layers a pliable film, e.g., aluminum foil of size sufficient to extend over the end of the container so that when the removed portion is replaced the foil can be used to substantially seal the replaced portion to the end of the container and to retain it there. Since the sealing surface is broken when the container is opened, any tampering with the container will be readily observable.

Abstract: A container has a tubular sidewall wall member having a coating of thermoplastic material on the inner surface thereof and a bottom member having a coating of thermoplastic material on the upper surface thereof. The bottom member has a central portion and a continuous skirt extending downwardly from the periphery of the central portion. The lower portion of the skirt is thermally bonded to the sidewall member while the upper portion of the skirt is free of any bond to the sidewall member. The bottom margin of the sidewall member can be curled inwardly to form a rolled rim to improve the impact resistance. In one embodiment the sidewall blank can have a coating of adherence-preventing material in the area which would be contiguous to the upper portion of the skirt. In another embodiment the upper portion of the skirt can be coated with an adherence-preventing material.

Abstract: A gable topped container and a paperboard blank for forming the containers constructed with ridge panels that are a substantially common width and with an end closure member having an interrupted, weakened line of severance at an elevation higher than the lowermost edges of the ridge panels with the uppermost edges of the roof panels and end closure member being at a substantially common elevation. The weakened line of severance is coated with a material being of a type for preventing sealing of the ridge panels to the portion of the end closure member covered by said material coating.
