Abstract: A tamper evident overcap has a tear band which is offset radially from both a ring member sonically welded to a container shoulder and a cap, by generally radially extending frangible bridges. The bridges are severed by applying force to a pull tab extending radially and axially from the tear band in alignment with a gap in the ring member so that there are no undercut faces on the overcap which can consequently be molded in a straight draw mold without cams or slides.

Abstract: A snap-on closure for wide mouth containers has an integral hinged lid which can be lifted, as by the thumb, to provide access for spooning contents out of the mouth. The lid closes on a top flange which is presented by either the closure or the container. The closure has a skirt and snaps onto the container below the top flange or to an attachment bead on the container.

Filled crates can be supported one on top of the other(s) in a stack with the blade (14) arranged to support the overlying crate. Empty crates can be nested in a compact condition with the blade (14) protruding slightly outwardly.

Abstract: Difficulties in removing a film-like seal (14) from the access opening (12) of a container (10) may be avoided in a container and cap construction including a container (10) whose access opening (12) has an edge (20) of circular shape and of a particular inside diameter, a cap (16) for the opening (12), snap-fit components (28, 30) or threads (140, 142) for removably holding the cap (16) on the container (10) to occlude the access opening (12), a membrane or foil-like seal (14) bonded to the container (10) about the access opening (12) to be free of the cap (16) and at least one cutting tooth (50, 104) carried by the cap (16) and displaced from a rotation point (54) on the cap (16) about which the cap (16) may be rotated relative to the access opening (12) a distance equal to or slightly more than one-half of the particular diameter.

Abstract: A reusable closure device which is especially intended for use on conventional 18.9 liter plastic bottles in common use for supplying bottled drinking water. The device includes a plastic cap with a replaceable resilient seal. A pair of levers are mounted on the cap for pivoting movement between a first position which allows the cap to be placed on or removed from the bottle and a second position in which cam surfaces on the proximal ends of the levers engage a groove in the neck of the bottle to press the cap down on the bottle. The levers are approximately L-shaped and legs of the levers containing their distal ends interengage in the second position to form a carrying handle. At the present time, the abovementioned bottles are provided with non-reusable heat-shrink plastic caps which are discarded by users resulting in environmental waste. The present invention eliminates this waste.

Abstract: A child resistant spout package wherein a plastic container includes a neck and a spout extending axially outwardly through said neck and the neck includes internal threads that are engaged by external threads on a closure which projects beyond the finish to accommodate the spout. The finish of the container includes an axially extending flexible wall. Interengaging ratchets are provided between a flange on the closure and the flexible wall of a container and are operable to normally permit rotation of the closure to apply the closure to the container but prevent rotation of the closure for removing the closure from the container. When the flexible wall is flexed at points spaced from the ratchet, the wall is deformed sufficiently to prevent the ratchet on the wall and the closure from engaging so that the closure can be rotated to remove the closure from the container.

Abstract: An electrical equipment enclosure (10) with an improved hinge pivot (12). Enclosure (10) has a box (20) having emboss (22) and hood (40) having embossment (44). The embosses forming a hinge pivot for slot (34).

Abstract: A device for manually opening and closing a vessel door the device including a fixed first bar and a moveable second bar mounted parallel to the first bar which when moved toward the first bar, permits relative movement of the door and insures automatic locking of the door in both open and close positions.

Abstract: A valving-type closure having a resilient diaphragm provided with a portion having a through slit for the passage of fluids, the slit portion being adapted to bulge and open the slit in response to fluid pressure applied to one side thereof. The slit portion has abuttable, cooperable structures on one side, which come into forcible abutment and act to physically open the slit as the portion bulges. Preferably the abuttable structures are in the form of rings molded on the underside of the diaphragm. The slit through the diaphragm also extends through the ring, thereby forming two semi-circular ring segments. The ring segments in turn form abutment shoulders that pivot the walls of the slit away from one another when the diaphragm is bulged, thereby resulting in a more pronounced spreading force being applied to the walls, and increasing the size of the opening formed by the slit.

Abstract: A new can top structure is provided in a can containing beverage liquid therewithin. On the can top, a ring serving as a jig for forming an opening therein is attached by way of a rivet at the center thereof. The ring has a pull side free end and a push side free end. There is also formed a tear-out portion defined by a scored line in the can top and the push side free end of the ring overlaps part of the tear-out portion. Since the ring is oriented slantwise with respect to the tear-out portion, the ring stays out of the way at the time of consuming the beverage liquid even though the pull side free end of the ring is erected to cause the push side free end to drive part of the tear-out portion into the can such that an opening is formed.

Abstract: A container (1) having a lid part (4) which is pivotally connected to the container by means of a pivot device (6), and which is provided with a handle part (5) which extends from the pivot device (6) in a direction opposite to the direction in which the lid part (4) extends. The container has a bottom and an outer surface which extends from the bottom, and presents at the end of the surface remote from the bottom a neck portion (2) which is terminated with an opening. The container is characterized in that the pivot device (6) can be moved circumferentially around the neck portion (2) so that when closing the lid part (4), the handle part (5) is moved from a position in which it extends essentially contiguous with the container surface to another position in which the handle part (5) is spaced further from the container surface.

Abstract: A vented hatch cover for an enclosed vessel having a cover body sized to overlie and cover a hatch opening defined by an upstanding coaming. A pair of air passages are defined by the cover body and a pair of hoods connected thereto. The hoods define air inlet opening and a plenum which communicates with air outlet openings in the interior of the cover body. The air passages permit air flow in sufficient volume to vent the vessel and to empty the vessel by high speed vacuum unloading. A filter is removably retained on the hoods in the air inlet openings. A filter screen on the interior of the cover prevents contamination of the air passages from the inside. A latching arm provides downward pressure on the hatch when in a sealing position and the capability of pivoting the hatch cover together with the latching arm when it is moved. The cover is floatingly engaged in the arm.

Abstract: Containers used for packaging aseptically batched liquid food products, typically fruit juices, puree and pulp, are stoppered by a plug (1) inserted into the relative mouth or filler neck (6); the plug is shaped and molded such that an annular flash left by the molding process, is positioned away from the area of contact between the plug and the mouth of the container.

Abstract: A closure cap for an automotive fuel tank displays informational indicia on one or more flags which are caused to project from the periphery of the cap when the cap is twisted for removal from the tank filler tube. The cap is constructed with two coaxially mounted plate members which are rotatably moveable relative each other by the act of twisting the cap off or on the filler cap. The relative movement of the two plates is utilized to propel the flags back and forth between one position in which the flags are disposed substantially entirely within the periphery of the cap and another position in which the flags extend substantially beyond the periphery of the cap.

Abstract: A medication container stopper includes an elastomeric plug which makes a friction fit in an opening of the container. A first cavity in an exterior surface of the plug opens and diverges away from an interior surface of the plug. A second cavity opens qnd diverges away from the exterior surface of the plug. The bottoms of the cavities are spaced apart to define opposite faces of a thin diaphragm formed integrally with the plug. One of the cavities has an elongated groove with a bottom which defines one face of the diaphragm, which is of a thickness that permits the diaphragm to be ruptured by inserting a conventional hypodermic syringe nozzle into the cavity in the exterior surface of the plug.

Abstract: In containers (1( with a screw cap closure (2), both of plastic, the sealing and the firm fit of the screw-cap (2) are improved, in the event of the container dropping, by virtue of the fact that a conical sealing ring (10), which presses from the inside against the mouth rim (5) of the pouring spout (3), is combined with an O-ring seal (13), which is inserted in an undercut annular groove (11) sunk in the end face (6) of the screw-cap closure (2) between the conical sealing ring (10) and the peripheral wall (7), and that in the closed condition the mouth rim (5) bears tight against the peripheral wall (7).

Abstract: A container for storing a hazardous product, a lock ring and a safety closure placed over the lock ring and threaded to the container. An extending tab portion of the lock ring extends from the bottom of an annular slot in the neck portion of the container. An extending neck portion of the container and a peripheral wall of the lock ring positioned over it, both have an offset axis displaced about the same distance from a central axis of the mating threads on the closure and the container. These offset axes are positioned in alignment to permit closure removal when an alignment bar portion of lock ring is in contact with a shoulder of the annular slot in the neck portion of the container. Serrations on the outside serrated surface of the lock ring and the inside serrated surface of the closure, are concentric with the threads on the closure and the container when the offset axes are in alignment.

Abstract: A plastic, tamper resistant container particularly adapted for the marketing of dairy products comprising a cup and a lid having a tab extending peripherally therefrom such that application of a force to the tab sufficient to remove the lid, initiates fracture propagation and tearing of the lid, and a process for manufacture thereof.

Abstract: A tamper indicating closure for application to a container neck. The closure includes a cap having a top and an internally threaded skirt. A tamper indicating band depends from the bottom of the cap skirt by circumferentially spaced frangible connections. The band has ratchet teeth which engage ratchet teeth on the container neck, and a permanent tether rib connects the band to the cap so that the band remains with the cap when the closure is unthreaded from the container neck.

Abstract: A tamper-indicating plastic closure includes a pilfer band at least partially detachably connected to a skirt portion of the closure by a frangible connection. The frangible connection comprises a plurality of circumferentially spaced frangible bridges, which fracture attendant to removal of the closure from an associated container to provide visually discernable evidence of opening. In order to facilitate high-speed application of the closure to a container, one or more regions of the frangible connection are preferentially strengthened by the provision of relatively strengthened frangible bridges. At least one of the strengthened bridges is generally diametrically opposed to the leading portion of the internal thread formation of the closure.
