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 lipstick or cosmetic dispenser having a tubular cam sleeve and an innerbody fitted inside the cam sleeve, and internal helical tracks supporting an elevator cup. The cam sleeve has a lower cam skirt with a plurality of ribs provided on its inner wall. The innerbody has a beveled shoulder around a lower outer wall thereof. The cam skirt ribs bear against the beveled shoulder to create frictional drag between the innerbody and the cam sleeve, and to cause the cam sleeve to be urged upwardly. The ribs on the inner wall of the cam skirt extend at an angle relative to a centerline of said dispenser, and preferably are angled the same direction as the internal helical tracks of the cam sleeve. There are from three to seven, preferably, five or six of said ribs located equidistantly from each other around said inner wall of said cam skirt. The ribs may be connected with each other by webs or separated by slots.
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 of washing a container,including charging a material to be contained into a container body having a mouth-and-neck portion; mounting a container closure on the mouth-and-neck portion of the container body, the container closure having a top panel wall, a cylindrical skirt wall extending downwardly from a peripheral edge of the top panel wall, and a washing liquid passage formed in at least one of an upper portion of the skirt wall and a peripheral edge portion of the top panel wall; and jetting a washing liquid at the container closure so that the washing liquid passes through the washing liquid passage and enters a space between the mouth-and-neck portion of the container body and the skirt wall of the container closure, thereby washing an outer peripheral surface of the mouth-and-neck portion of the container body and an inner peripheral surface of the skirt wall of the container closure. The washing liquid is at a temperature of 65° C. to 70° C.
Abstract: A dispensing closure for a container that contains a flowable product such as a bath gel includes a body member that is constructed and arranged to be mounted to the container, that includes a dispensing opening and a further includes an upper deck portion, a lid member that is hinged to the body member and that includes a cover portion and at least one downwardly depending sidewall, and a snap fit mechanism for releasably locking the lid member to the body member. The downwardly depending sidewall portion of the lid member and the upper deck portion of the body member are advantageously configured to form therebetween a watertight seal when the lid member is in the closed position.

Abstract: A can lid having a top plate, a tab, a rivet, a score, a tongue, a first deboss, an emboss, a second deboss, and an embossed ridge. The first deboss is formed entirely within the score. The second deboss and emboss are formed entirely within the first deboss. The second deboss is formed by matching arcuate sidewalls, and has a sloped bottom surface. The rivet is offset from a center of the lid. The tongue is disposed between the rivet and top plate perimeter where the rivet is closest to the perimeter. The emboss is uniformly spaced from the score. An embossed ridge is uniformly spaced from the score outside of the score. In another embodiment, the second deboss is replaced with a contact emboss. A die insert for forming the first deboss, emboss, and second deboss (and, alternatively, contact emboss) is also disclosed.

Abstract: A snap-on or screw type, tamper evident closure having first and second relatively moveable plastic parts (16, 18) which move from an initial position to a new limiting position when the closure is first opened, the new limiting position being visually distinguishable from the initial position to provide the tamper evidence. The two plastics parts are formed in mutually intimate association but have inter-engaging complimentary formations (22, 28, 40, 42) which become irreversibly disengaged on first opening of the closure.

Abstract: A sealing member for a cap featuring excellent cap performance as well as excellent safety and environmental friendliness, and a metallic cap. A foamed polyurethane elastomer having a JIS A hardness of from 15 to 65 and a foaming magnification of from 1.1 to 10 times is used as the sealing member so as to obtain excellent sealing performance, durability, safety and environmental friendliness. The sealing member is provided for a metallic cap shell that has a polyester film formed on the inner surface of the cap, thereby to obtain a cap featuring excellent sealing performance, durability, safety and environmental friendliness.
Abstract: A dispensing closure (1) incorporating a flexible, self-closing valve (5) and a transport seal for preventing accidential dispensing of product through the valve during transportation and storage of a filled container. The closure includes a cover (4), which is adapted to move axially between raised and lowered positions, to actuate the transport seal. The transport seal comprises a sealing plate (8), located between the valve and the container opening, which partially occludes the container opening but defines at least one dispensing orifice (9). To form the transport seal, the cover is lowered so that it presses part of the flexible valve against the sealing plate around the dispensing orifice/s, thereby blocking the dispensing passageway to the valve.

Abstract: A pourer spout for a composite package of the carton brick type, arranged to be located level with the opening zone of the latter. The pourer spout comprises a base (2) fixed onto the container around the opening zone, and an articulated cover (4), able to reclose the container after opening. A perforating piece (6) is mounted pivotally on the base (2), facing the opening zone, in order to be moved between an initial position in which it is situated entirely outside the container to a final position in which it is situated substantially inside the container. A striker (8) is mounted pivotally on the base (2) in order to push the perforating piece (6) towards the inside of the container while perforating the wall of the latter and to more or less take the initial position of the perforating piece (6), the striker (8) in this last position acting as pourer.
