Abstract: A shelf-stable combination of an easily openable bag and a mixture of edible popcorn ingredients is suitable for use in microwave ovens. The bag includes a bottom panel, a top panel, a back panel, and inwardly folded gusseted side panels such that the bag can be flattened along the top edge opposite the bottom panel. The bag is formed by an outer layer of paper and an inner layer of non-wicking material with a coating that is sensitive to a combination of heat and pressure. A peelable seal is formed by the coating along the top edge such that the bag can be opened along that edge by pulling on diagonally opposite corners. The ingredients include corn kernels having a moisture content of about 11.5 percent or more and the peelable seal has sufficent strength to remain closed for at least one-half of the time required to pop substantially all of these kernels. The top edge seal opens before popping is completed to release steam and prevent the popped corn from becoming too chewy.

Abstract: An extrusion blow molded container is provided having an integrally formed generally annular pouring lip including an upwardly facing convex surface beginning at a generally vertical inner wall of the container and curving through an arc of less than 180 degrees. The lip is undercut forming a sharp downwardly directed annular edge on the lip. The lip can be formed by cutting the lip with a downwardly curved cutting tool bearing against an upwardly curved anvil, the cutting tool forming the upwardly facing convex surface of the lip and the anvil forming the undercut lower surface of the lip.

Abstract: A pouring fitment defines an inwardly facing recess that receives an outwardly extending annular holding portion of a mating container and an annular sealing bead on the fitment engages the holding portion. A lip of the fitment that defines a pouring surface is received and deformed by a cradle defined by a closure. Extending downwardly from the closure is a support member that presses the fitment against the container.

Abstract: A generally annular pouring fitment is forced into a closure, thereby deforming a lip of the fitment elastically and inelastically. The closure is then releasably secured to a container causing the fitment to permanently interlock with the container. When the closure is removed, the lip defines a pouring surface of a desired three-dimensional configuration.

Abstract: A dust cover for an aerosol container includes a cup-shaped body placed over the dispensing valve of the container in an inverted position. To secure the cover, one or more fixed lugs project inwardly from the bottom edge of the body to engage a rim on the container. The cover is further secured by a release lug. A tab attaches the assurance lug to the body, the tab being permanently deformable to cause the assurance lug to be disengaged from the rim. The cover can then be removed by disengaging the release lug which is moved from its normal position by an actuator.

Abstract: False positive reactions with fluorescent antibodies such as Lactobacillus reaction with IgG-antiSalmonella are avoided by enzymatic treatment of the IgG to remove the non-antibody, Fc, fragment of the IgG.

Abstract: Apparatus for sorting firm whole fruits and vegetables from those which are soft and broken by sliding or rolling the specimens to be sorted down an inclined plane to impart momentum and velocity and then dropping them on a rearwardly moving conveyer belt. The firm whole specimens will have achieved sufficient forward velocity on the inclined plane to overcome the rearward motion of the conveyer belt while the soft broken specimens will be carried rearwardly with the belt.

Abstract: Crude vegetable oil is dewaxed by admixture with a mixture of surfactants comprising an aqueous solution of less than 100 ppm of a sulfosuccinate alkyl ester such as dioctyl sodium sulfosuccinate and 0.01 to 0.5% of a fatty acid sulfate such as sodium lauryl sulfate. The oil is then centrifuged and washed. The oil can be simultaneously degummed by the addition of a phosphate compound to the treatment liquid.
