Abstract: A plastic container closure has a skirt which is connected to a tamper-evidencing band by frangible bridges, all molded in a single unit. Where the closure is a cap for a container neck, there is at least one retaining means on the skirt and another on the band. The neck has two retaining means which cooperate with those on the cap to prevent upward movement of the cap without fracture of the bridges. To reduce the likelihood of unintentional fracture of the bridges, particularly during installation of the cap on the neck, plural ejection bumpers of extended arcuate lengths are located on the top edge of the band and or from the bottom edge of the skirt and the bridges are located between the bumpers. This snap lock ring functions to replace the conventional retaining means located centrally of the band. The invention is applicable to tamper-evidencing bands of closures and of push/pull closures of sports-type cap spouts.

Abstract: The present invention is a disposable device which is attached to the tab of a conventional aluminum beverage can at the time of manufacture. When a consumer pulls the device upward, the tab is likewise pulled upward to a position in which the consumer can easily grasp the tab and consequently open the can. Two embodiments of the present invention are provided.

Abstract: A closure device (10) for pet food cans comprising a central cover member (12) and an outer cover member (14) which are integrated into the shape of a pet having protruding features (16), said protruding features providing a means of prying the device. Extending downwardly from the cover members (12 and 14) are a plurality of concentric annular bands (18), each having a bead or rib (20) extending inwardly from the inner surface.

Abstract: A differential pressure sensor having a vent to atmosphere and mounted where it is subject to water spray has a vent cap which protects against spray entering the vent and prohibits water residing along the cap edges from being drawn into the vent. The vent is surrounded by an upstanding collar and the vent cap snaps onto the collar. A shroud extends laterally from one side of the cap to a point beyond the sensor package and further extends down below the upper surface of the package. The shroud is open at the bottom to afford an air passage to the vent as well as a baffle against spray.

Abstract: The invention, relating to an easy-open metal container end, places a portion of the metal of the tear panel (12), in the region where a score stop otherwise would be located, under compression by forming a short coined depression or bead (40) in the tear panel, preferably in the public side, close to the score line (15) at least at the end of the vent region (35) opposite from the inner hook (16), which is located at the radially inward end of the tear panel score line. During initial opening or venting action, as the rivet (25) is lifted by initial tab motion, separation proceeds along the score line, beneath the nose (28) of the tab (27). The metal adjacent and in this coined depression tends to move partially underneath the metal on the opposite side of the score line from the coined vent bead. This action provides sufficient disruption or retarding of the score line separation or rupture, during venting, to confine such separation to the vent region until internal pressure is vented.

Abstract: A removal resistant closure cap for a container having a standard threaded neck is disclosed. The cap does not have a thread complementary to the container neck thread but has an inwardly projecting circumferential bead with an intersecting projection extending downwardly from the bead at the helix angle of the container neck thread. When the container neck is engaged by the cap with a threading rotation, the cap projection will engage the container neck thread, and the cap bead will snap over the container neck thread, permanently retaining in the cap on the container neck.

Abstract: A squeeze and turn child resistant package including a container having a finish and a closure having a base wall and an outer peripheral flexible wall depending from the base wall. The wall has an internal thread on the inner surface thereof, the finish has an external thread thereon. The closure has an internal surface with spaced flexible chordal lugs extending circumferentially in the direction of removal of the closure. The container finish has opposed radially extending abutments. Each abutment includes a radial abutting surface. The finish of the container includes an integral radial projection adjacent the radial abutting surface of the abutment which has a lesser radial extent than the abutment. The radial projection has a chordal surface extending to the intersection of the radial abutting surface on he finish such that the chordal lug on the closure is forced toward the intersection when a closure is rotated in a retrograde direction to remove the closure without flexing the peripheral wall.

Abstract: A lug lid (10) which closes an open head pail (12) has lugs (31) that overlap the annular rim (19) of the pail and which are crimped thereabout to attach the lid to the pail. An annular expansion bead (38) is formed in the lid to enable the lid to expand to relieve some of the increases in internal pressure which might occur in the container. Sacrificial depressions (46) are formed in the lid (10) adjacent the expansion bead (38) with each sacrificial depression radially aligned with a lid lug (31). The sacrificial depressions selectively weaken the lid to control the formation of wrinkles (47) in the lid in response to increased pressure within the materials container, with such wrinkles being formed in radial alignment with the lugs of the lid, where the connection between the lid (10) and the pail (12) is strongest.

Abstract: A lid for a beverage container having a lifting tab is affixed to the lid by a staking member or rivet which serves as a fulcrum about which the tab pivots. The staking member is disposed radially from the center of the lid. A line of weakness defining a rupturable area in the lid is formed between the staking member and the periphery of the container, and defines a fruto-conical configuration so as to subtend an angle of at least about 90.degree.. The line of weakness is nearly completely continuous, but has one relatively small broken zone whereby the severed area circumscribed by the line is retained by the lid at the broken zone when the area is ruptured to create a hole along the line. The staking member is disposed radially from the center of the lid by at least about 2.5 mm., and the remaining surface area of the lid outside the rupturable surface area defined the line of weakness is greater than if a staking member were disposed in the center of the lid.

Abstract: A child-protected thermoplastic container having a generally square shape including a closure having horizontal sealing surfaces complimentary to sealing surfaces on the top of parallel container sides, and including tapered guide surfaces on the parallel sides to guide the closure from back to front for closing while forcing a tight seal on the sealing surfaces.

A plurality of rows of notches include a first set of rows of notches disposed on one of the hollow bodies, the rows of notches of the first set being disposed diagonally opposite one another on corresponding longitudinal edges of the one of the hollow bodies; and a second set of rows of notches disposed on another one of the hollow bodies, the rows of notches of the second set being disposed on all longitudinal edges of the other one of the hollow bodies.

Abstract: A dynamic joint connection is provided between the neck region of a base and the engagement end of a cap. The neck region comprises a reduced diameter end of the base which is offset from the base outer wall by a flat ledge. Located above the ledge a first axial distance, is a first convex rib. The interior surface of the cap engagement end is provided with a cap rib which is located a third axial distance above its abutment end. The third distance will locate the cap rib against the first rib on the down-sloping portion of its surface when the cap abutment end is in contact with the neck region ledge. The compressive force of the cap ring against the first rib will cause the abutment end to be biased downwardly against the ledge. This unstable condition creates a dynamic connection that maintains its integrity throughout rough handling, internal pressures and varying ambient conditions. The neck region can include a second rib.

Abstract: An arrangement (A) on infusion bottles (1), or the like, having a cover (7) which has several foil-covered puncture regions (13), which cover is held by a cap (8). In order to obtain individual accessibility despite the overall covering, the cover foil (15) has an intended tear line (17) between the puncture regions (13) and forms, on both sides of the intended tear line (17), grip tabs (18) which protrude beyond the contour of the cap (8).

Abstract: A tamper-evident thermoplastic fitment having a spout and a closure for said spout are welded to a polymer-coated paperboard container or to a flexible plastic container. The fitment and closure are initially molded simultaneously but with a substantial space between the two pans interconnected by an elongated runner which conducts molten plastic from the closure to the fitment. Upon retraction of the core of the mold, the closure is pulled into the spout until shoulders on the parts engage, whereupon the closure is stripped from the mold core. The runner comprises a tear tab which slides through an apertured space on the closure. When the parts engage tangs on the tear tab engage the space, making the assembly tamper-evident. The fitment has a flange which may be welded or otherwise secured to the container. The tab may be pulled by the consumer to open the container. The closure may be unscrewed from the spout or otherwise disengaged.
