Abstract: A molded cap is disclosed having a sealing ring groove just below the cap handle in order to seal crank case gases in an internal combustion engine. The cap includes two spiral grooves for engaging a respective protrusion formed on the inner annular surface of an oil fill snout which receives the cap. A recess is formed at the end of each spiral groove for receiving a respective protrusion to lock the cap into the oil fill snout. The oil fill snout has a draft angle to provide an outside vertical force component on the cap and sealing ring. The vertical force locks the protrusions into the respective recesses and provides a positive sealing force to the sealing ring when the cap is twisted into the snout and into the closed position. The two spiral grooves increase the resistance to back out and create symmetric force components. At the entrance of each groove, a lead-in angle is used to free the cap from the cover by continuing to turn the cap in a counter-clockwise motion.

Abstract: A container for transporting and storing vessels containing hazardous liquids and a method for making such a container. The container has a cylindrical housing and a cap that screws into the mouth of the housing and is locked by a latch. When the cap is screwed into place, an elastomeric sealing ring on the cap is compressed against the housing to provide a liquid-tight seal between the housing and cap. Interlocking hook-shaped members that project from the housing and from a central location of the latch act as a fulcrum on which the latch can be pivoted. Under the bias of a serpentine tongue, a locking member that projects from an end of the latch protrudes through a bore in the housing and is adapted to be received by a hole in the cap, thus locking the cap until the other end of the lever is depressed to disengage the locking member from the hole of the cap.

Abstract: A fitment attached around an aperture in a container has a flange from which extends an internally threaded spout closed by an initially integrally molded externally threaded plug. The plug is moved axially into the spout, the threads slipping over each other. The plug has an outward extending slotted ear and the fitment has an upward extending finger aligned with the slot in the ear and formed with tangs which lock the finger and ear together as the plug is moved to the spout, thereby making the device tamper-evident. As a further feature of the invention, an over-size foil seal extends across the bottom of the flange and is welded or otherwise adhered to the bottom of the flange. After assembly the portion of the foil extending outside the flange is welded or otherwise adhered to the carton. This further feature is particularly useful in aseptic packaging. Optionally the lower edge of the plug may be welded to the foil so that when the consumer unscrews the plug the foil under the spout is torn away.

Abstract: A caulk cartridge cap is designed to enable the storage of unused portions of products of the types supplied within caulk cartridge type containers to thus maintain them in a reusable condition. The cap operates as a closure for purposes of resealing a caulk type cartridge to prevent the premature drying out or aging of the materials stored within the cartridge and to also prevent blockage within the cartridge applicator tube. The cap includes an orifice retention rod which is positionable within the applicator tube, and a self-threading insert positioned within the cap is then used to threadably attach the cap to the cartridge. Modified embodiments of the cap include the use of a tether, a scraping edge formed on the orifice retention rod, and a bracket assembly to which the cap is rotatably attached and which may be mounted to a conventional caulk cartridge holding gun.

Abstract: A closure with repressurizing apparatus for a carbonated beverage container used as an original factory closure cap or as a replacement to the factory closure. An internally threaded closure which is secured to seal the mouth of a container is combined with a pump cylinder and a hand operated air pump to repressurize the container. The pump cylinder is molded with one or more internal ridges that extend from the base of the pump cylinder to approximately three quarters the length of the pump cylinder. A valve is created when this ridge(s) interacts with the corresponding notch(es) formed on the base of the piston. The valve allows ambient air past the base of the piston only when it is above the ridge(s) on the pump cylinder.

The deadender cap is a one-piece molded construction having an internal tapered projection that fits within the open passages of the male Luer connection a predetermined distance when the deadender cap is tightened into position, thus liquid within the open passage is forced outwardly and then as the deadender cap is tightened and no air bubbles are formed.

Abstract: A fitment and cap therefor are integrally molded with lugs interconnecting the part. The fitment has a flange to be attached to a container and an internally threaded spout. The cap has an externally threaded skirt. The lugs are diametrically spaced and interconnect the bottom edge of the skirt and upper edge of the spout. After molding, force is applied to break the lugs and snap the skirt inside the spout, the threads slipping past each other and inter-engaging. A temper-evident band extends around the skirt and is connected thereto by frangible bridges. At diametrically spaced locations vertically projecting fingers extend down from the tamper evident band and are received in sockets on the fitment flange shaped so that the band fingers prevent unscrewing the cap without removing the tamper-evident band. A pull tab and thumb tab assist the consumer in removing the tamper evident band so that the cap may be unscrewed from the fitment.

Abstract: The invention provides a plug for sealing substances in holes drilled in wood. The plug has a body of generally circular cross section and a thread portion helically wound around the body between inner and outer end portions thereof. The thread portion has a leading face facing towards the inner end portion and a trailing face facing towards the outer end portion, the leading face being inclined at a shallower angle to a central axis of the body than the trailing face. The plug can be driven into the hole by hammering, but is extracted from the hole by unscrewing in a normal manner. The thread portion is designed to permit relatively easy movement into the hole without rotation, but requires rotation for extraction from the hole. Preferably, the thread portion is flexible and the thread portion is within a shallow conical periphery. The outer end portion has a recess to receive a complementary driver to rotate the plug for extraction.

Abstract: A flexible diluent container has a vaned port plug which enhances or modifies the mechanical interlock with a stopper of an additive vial in a drug delivery system. The additive vial is screwed into the port of the diluent container with the recess of the vial stopper fitting over the engagement portion of the port plug. In doing so, the vanes or wings of the port plug present a minimal frontal area and hence minimal resistance to passage through the neck of the stopper recess. Also, being flexible, they tend to fold or wrap in against the core of the extractor as the vial and stopper are rotated and advanced into the seated position, thereby further reducing the axial forces involved.

Abstract: In an insulating jug (1) having a stopper (4) on which is arranged a sealing element (13) having a generally radially extending sealing lip (16) that in the closed position lies on a generally radially extedning sealing surface (19) on the housing (2) of the insulating jug (1) , a reliable seal is attained even when there are relatively large discrepancies in the relative dimensions of the sealing parts. This is achieved through the bending stress of the sealing lip (16) being greater than the force extended on the sealing lip (16) by the fluid in the container, and by arranging a free space (23) on the side of the sealing lip (16) facing away from the sealing surface (19).
