Abstract: A system is disclosed for detecting or inspecting for a lining of a container closure that is formed of a sheet metal and has a panel on an inside surface of the closure. The panel of the closure has a lining formed thereon. The system according to the present invention includes a conveyor for moving plural closures longitudinally and substantially through the system, a color sensor that inspects the panel of each one of the closures on the conveyor for a predetermined color, and a separator that is capable of removing closures that lack the predetermined color. The system may include an oven downstream from the sensor to bake the lining. Thus, the system automatically identifies and removes the closure having the deficient color from the conveyor. A corresponding method for identifying and removing a closure having a deficient color is also disclosed.

Abstract: A method of making an easy-open end for a container includes steps of forming first and second grooves in a panel of a can end blank, the grooves extending below the level of the panel to form inner and outer beads and forming a central bead in the panel between the first and second grooves so that the central bead extends above the panel. A score is then formed along the central bead by simultaneously forming the score and compressing the central bead, so that the depth of the score and the thickness of the central bead are both positively controlled. The inner and outer beads are then forced toward each other and then toward the panel, and the central bead is forced toward the panel. A pull-tab is then fixed to the end. This process permits the score residual to be controlled to a greater tolerance than the conventional processes, and is also more material efficient.

Abstract: An easy open safety end having a central portion and a rim portion separated by a score line. A tab applies a force to the end adjacent the score line so as to shear the score line at opening. A circumferentially extending fold is formed in either the central portion or the rim portion, or both, to protect the user from being cut by the sharp edge the results upon shearing the score line. A first circumferential portion of the fold is tight, whereas a second portion, which is preferably proximate the tab is loose. The fold is displaced below a portion of the end adjacent the score line by a circumferentially extending gap. In the tight portion of the fold, the width of the gap is less than the thickness of the end, and preferably less than one half the thickness, whereas in the loose portion of the fold, the width of the gap is greater than the thickness of the end, and is preferably at least twice the thickness of the end.

Abstract: A dual cosmetic applicator is formed from two applicator units, each of which includes a cap from which extends an applicator and an internally threaded sleeve facing the applicator. An enclosure includes an externally threaded end portion adapted to threadably engage the internally threaded sleeve of the cap. Each applicator unit also includes a coupling member which is formed by a central internal member surrounded by a peripheral wall, the peripheral wall having a plurality of projections laterally extending therefrom beyond the central internal member and a plurality of recesses corresponding in size, shape and number to the projections. An inner surface of the projections includes one half of a mating pair of snap fitting elements, while an outer surface of central internal member adjacent the recesses includes the other half of the mating pair of snap fitting elements.

Abstract: A closure cap (1) with a cap base (2) and with a cap skirt (3) comprises an inner seal (4). The inner seal is provided with bleeding reliefs (11) which lift the sealing effect as soon as the cap base (2) is displaced axially upwards. The closure cap (1) comprises a first abutment and a second abutment (8). On screwing-on firstly the second abutment (8) comes into engagement with the container opening. By way of this a weakening zone (9) in the region of the cap base (3) is pretensioned to a predeterminable value. On account of the predeterminable pretensioning of the weakening zone (9) a bleeding at an exactly defined excess pressure is possible.

Abstract: A can end is manufactured by forming an end shell comprising a radially outer seaming flange, a chuck wall adjacent the seaming flange, a center panel, and an axially downward countersink joining the center panel to the chuck wall below the level of the seaming flange. The end shell is converted to an easy-open can end by forming a score on a portion of the center panel, raising a rivet on the center pane, and forming a tab and attaching the tab to the rivet. The end is subsequently formed by moving the center panel and the seaming flange one with respect to the other to raise the center panel above the level of the seaming flange.

Abstract: A composite closure includes a band and an insert disk. A contact surface urges downwardly against the disk even while the band moves longitudinally relative to the disk or container. The closure has a fully tightened position in which the band's ring contacts the disk's annular channel, a loose position in which the ring is spaced apart from the annular channel, and an intermediate tightened position in which the ring is spaced apart from the disk and in which the contact surface urges against the curl. A retaining feature, which presses upwardly against the disk during the opening process, defines a gap in which the disk curl is disposed.

Abstract: A dispensing closure (18) for a container (10) of liquid product (70, 72) which is sealed by a piercable diaphragm (16). The closure includes a piercing member 924) which is moveable through a predetermined distance towards the container and which has a cutting edge arranged to pierce the diaphragm to form a dispensing aperture. At the end of its movement towards the interior of the container, the piercing member is arranged to plug the dispensing aperture against escape of the product when the container is inverted prior to dispensing. The closure is particularly useful for liquid products which tend to separate into a lighter (70) and heavier (72) fraction during storage. The closure prevents dripping of the lighter fraction when the container is inverted and allows the heavier fraction to displace the lighter fraction adjacent to the dispensing aperture before dispensing occurs.

Abstract: A molded polymeric container includes a body portion having a sidewall and an integral champagne type base. The base includes a lower end that defines an annular contact ring for supporting the container with respect to an underlying surface. An annular step ring is defined immediately radially inwardly of the annular contact ring and has a radial length LS. The base further has a central push-up area and a generally concave transition region interposed between the central push-up area and the annular contact ring. The transition region further includes a plurality of integrally molded radially extending ribs, each of the ribs having a length LR. According to one advantageous aspect of the invention, the ratio LR/LS is within a range of about 1.0 to about 4.0.

Abstract: A resealable single-piece push-pull dispensing closure is disclosed that includes a circumferential skirt, a top member circumferentially coupled to the skirt, and a sipper spout. The sipper spout extends upwardly from the top member and has a curved sipper surface that truncates to from a substantially flat landing surface. Plural apertures are disposed in the landing surface, and apertures may be disposed at a periphery of the sipper surface. The curvature of the sipper surface has a constant cross section curvature throughout the width of the sipper surface. A user's lip may rest on the sipper surface while drinking directly therefrom, or the top member may have a concave portion in which a user's lip may rest during drinking.

Abstract: A system for pressure molding plastic material includes a source of hot flowable plastic material and a manifold for receiving hot flowable plastic material from the source and for transporting the hot flowable plastic material to a nozzle that is disposed within a nozzle cavity. A heater is provided to heat the nozzle and is positioned outside of, but close to, the nozzle cavity and includes at least one electrical supply wire. A shut-off seal is positioned within the nozzle cavity to seal the nozzle with respect to the wall defining the shut-off cavity. In addition, a secondary seal is most advantageously positioned between the shut-off seal and the heater for ensuring that any hot flowable plastic material that might leak through the shut-off seal does not come into contact with the electrical supply wire. This has been found to increase the reliability and operating life of conventional pressure molding systems.

Abstract: A method for manufacture of a metal cosmetic case having contrasting bright areas and duller textured areas, comprising the steps of: fabricating a cosmetic case from aluminum alloy; including polishing the cosmetic case and applying a surface texture to portions of the cosmetic case to form textured portions thereon; anodizing the cosmetic case to provide a bright shine to at least the outer surface of the cosmetic case; and printing over the textured portions with an ink to provide the textured portions with a contrasting finish to the bright shine of the outer surface of the cosmetic case.
