Abstract: A fuel cap comprises a cap body, a flange member projecting outward in radial direction on upper side of the cap body, and a weak portion which is easily broken and provided at the flange member and enables separation of the flange member from the cap body. The weak portion is formed by a plurality of V-like grooves at upper surface side which are formed on the upper surface of the flange member in concentric relation and a plurality of V-like grooves at lower surface side which are formed on the lower surface of the flange member in concentric relation and adjacent to the V-like grooves at upper surface side.

Abstract: A closure and container for specimens or the like have interlockable detents which connect together when the closure is forcibly disposed in closing relationship with the container. The upper portion of the container has a dome portion and the closure member has a cooperating dome portion, the detents being formed in the respective dome portions. The detents have surfaces which permit a sealing connection but prevent the release of the closure from the container. The closure member has a neck including a frangible section which must be broken in order to gain entry into the container once closed by the closure member. The closure member also has a cap above the frangible section having screw threads about the exterior periphery which threadedly connect to internal threads within the neck of the closure member adjacent the frangible section so that the container may be reclosed for further use.

Abstract: A closure cap is disclosed for sealing containers and particularly for sealing thin-walled vacuum formed containers with threaded rims. The closure cap is a composite closure having a molded plastic ring for engaging the container and for mounting a disc-like metal cover. The metal cover includes a vacuum indicating disc particularly adapted for providing a positive indication for relatively low vacuums and the closure cap is adapted for being sealed onto the container with a combination of press-on and screwing action to provide for high speed vacuum sealing. The vacuum indicating action of the vacuum button is improved by providing a channel in the plastic ring at the edge of the metal cover for stablizing the button operation at the desired low vacuum levels.

Abstract: A tamper indicating package in which the tamper indicating element is located on the container neck. A satellite ring is integrally molded with the container neck being connected thereto by a frangible connection between the ring and an integrally molded container neck flange. The frangible connection is broken to remove the closure from the container neck. Standard caps can be used on the container.

Abstract: A neck structure for a bottle-shaped container formed of synthetic resin, and associated with a rolled cap member having a top-closed cylindrical shape and constructed of thin aluminum plate at a cylindrical neck portion of the bottle-shaped container. The cylindrical neck portion has threads circumferentially formed on the outer periphery of the upper end of the cylindrical neck portion; at least one thick cylindrical portion of relatively large diameter is formed between the upper end of the cylindrical neck portion and the lower end of the cylindrical neck portion. The connecting portion is formed with a plurality of longitudinal strips on the outer periphery thereof and recesses between the longitudinal strips. The neck structure of the synthetic resin bottle-shaped container is constructed to be adapted to be associated with a tamper-proof-cap such that the lower end of the tamper-proof-cap is relatively increased in height.

Abstract: A child's liquid drink container in the form of a canteen which is equipped with a drinking straw. The canteen has a dome-shaped rotatable cover with a hole in one side. The cover may be rotated to a first angular position in which an internal closure member closes the hole with the straw retracted into the cover. The cover may also be rotated to a second angular position in which the closure member moves away from the hole and in which the straw is caused to project out through the hole. This enables one to drink the liquid contained in the canteen quickly and easily and without the need to remove the cover.

Abstract: An improved linerless plastic closure for large mouthed bottles and jars includes a plurality of ribs, at least one of which is wavy, projecting downwardly from the undersurface of the closure so as to contact the upper edge of the bottle or jar mouth. The wavy ribs give better surface contact with the upper edge of the bottle than conventional circular ribs.

Abstract: A device for clamping and locking of cover (6) against a flange (7) for subsea installations, particularly in connection with production of oil and/or gas, and particularly for clamping and locking of a valve housing cover (6) against a flange (7) on a valve housing (9) which is coupled into a subsea pipeline (1). Mainly U-formed locking segments (4) are designed with a certain clearance, preferably approx. 3 mm, so that the distance between the opposite facing, parallel contact and sealing surfaces of the locking segment (4) exceeds the total thickness of the cover (6) and flange (7) .

Abstract: An improved reinforced snap open hinged dispensing closure for a dispensing container. The closure having the snap open feature such that the closure lid is retained in an open position away from the dispensing opening of the container. The closure lid has a pair of hinges and a central tapered hinge strap formed therebetween. The hinge strap includes at least one reinforcing rib joining the hinge strap to the closure to improve the durability thereof.

Abstract: A tamper-evident closure cap and corresponding container have projections on a skirt of the cap corresponding to projections on a neck of the container. The skirt is conencted to a remainder of the cap by a series of severable tabs. The projections are shaped to override one another when the cap is turned onto said container but to interlock with one another when the cap is turned off said container. When the projections interlock, the force exerted on the cap severs the tabs, thereby severing the skirt from the cap and providing evidence of tampering. The cap and container are operable over a wide rnage of tolerances and the tabs can be very small when compared to previous caps and containers.

Abstract: A tamper-proof closure for a container having a discharge opening at one end and a wall member spanning the opening, inter-engaging locking between the skirt of the cap and the container opening, a tab projecting radially outwardly from the skirt registerable with a recess or gap in a radially outwardly directed flange of the container which it normally overlies, a fracturable tear band portion including inter-locking to prevent relative rotation of the closure and container.

Abstract: A polyethylene compression-molded closure with an elastomer liner that is removable, the elastomer being a blend of polypropylene and a rubbery copolymer.

Abstract: A bottle or container includes two semispherical parts which are fixed to each other and are equipped with valves at each end. The bottle can have an inner metal lining and a semispherical membrane which presses against the one part of the lining and has a flange welded between the two parts of the lining. The metal lining with membrane and end pieces forms a replaceable unit. By sampling, the bottle first is filled with a counter pressure medium, for example water, until the membrane lies tightly against one half of the bottle. The bottle is then filled with the fluid/gas-sample such that the membrane reverses as water is pressed out and the sample flows in. The membrane will reverse until it presses against the opposite hemisphere, and the bottle thereby is filled with fluid/gas sample.

Abstract: A one-piece molded plastic closure having a tamper-indicating band connected to the closure skirt by rupturable means. The tamper band uses series of solid interiorly projecting beads that come in contact with a transfer bead on the container as the closure is unscrewed. The engagement of the beads and container breaks the band by rupture on the connection means. The beads in the band are arranged in tiers at three different heights on the band. A thick cylindrical section at the bottom of the band assists initial capping. The beads are disposed in the band at an angle equal to the pitch angle of the container threads. This eliminates need for top pressure in capping by the beads following the container thread lowering and driving the beads over the container's transfer bead locking the band in place.

Abstract: The invention is directed to a reusable bottle cap which cooperates with a soda bottle or the like to maintain the required pressure within the bottle. The reusable bottle cap is secured to an open end of the bottle. The bottle, with the bottle cap secured thereto, is inverted such that the liquid contents of the bottle is provided adjacent the bottle cap. In this position, air is prevent from flowing into or out of the bottle, so that the pressure of the bottle is maintained over time and changing conditions. Support means are provided on the bottle cap to insure that the bottle will be maintained in the vertical position. Also provided on the bottle cap is a removal means, which cooperates with the original lid of the bottle, to easily remove the lid therefrom.

Abstract: A plastic cap for a container neck formed with upper and lower external locking beads has a top disk from which depends an upper outer skirt having an upper internal locking bead and a larger diameter lower skirt having a lower internal locking bead. Between the skirt sections is an external outward extending flange which is weakened by a notch cut in its outer corner. The interior of the skirt is formed with an outward extending shoulder at a lower elevation than said external outward extending flange and the lower skirt wall intersects said outward extending shoulder in a circular intersection. A circumferential line of minimum thickness extends downward-inward from said notch to said line of intersection. When the cap is seated on the neck the upper and lower beads interengage, the cap cannot be removed without evidence of tampering.

Abstract: A method for converting a thin-walled container to a jar with a rigid threaded neck which will accept a conventional threaded screw cap which comprises separately forming a thin-walled container and a rigid threaded neck ring and then attaching the ring to the outside of the container and the jar so made.

Abstract: A closure system includes a container and a closure comprising a cap having a cylindrical skirt with internal threads, an annular tamper band having an inside diameter larger than the outside diameter of the skirt forming an annular gap therebetween, and flexible bridges joining the tamper band to the free end of the cap skirt. The bridges have angularly spaced end segments extending radially outward and radially inwardly from the skirt and tamper band respectively, and an intermediate segment extending arcuately around the gap between the end segments. The closure is integrally molded with the bridges and tamper band extending radially outward in a common plane transverse to the central axis of the cap. The bridges flex to allow axial extension of the tamper band for bonding to a shoulder or transfer bead on the container. Unscrewing of the cap fractures the bridges, preferably at a section of reduced cross-section provided by notches at the intersection of the bridges with the cap skirt.

Abstract: A deep-drawn screw cap of aluminum for glass bottles under internal pressure, where the transition area between the upper end face 1 to the lateral thread face 2 up to now was always evenly deep-drawn, now is to have at least one undeformed partial area 8. Because of this, sealing against the lateral edge 7 of the mouth is partially disrupted and a chance for the escape of gas is purposely provided in case the internal pressure in the glass bottle should rise too high. If required, a plurality of such partial areas 8 may be provided. In the deep-drawing device for a sealing head for the production of such screw caps the inner recess 12 should provide at least one partial enlargement 14 oriented towards the center axis 13 and extending approximately to the diameter of the preceding recess 11.

Abstract: A closure cap for infusion and transfusion bottles having a rim cap which grips around a rim neck of a bottle and has a cutout which is closed by a plastic lid so that an annular zone of the plastic lid grips below the edge of the cutout to obtain a tightly sealed attachment of the lid this attachment can nevertheless be lifted off with relatively little force due to a radially extending intended-bend line of the plastic lid formed by a thinning of the material.
