Abstract: A method of injection moulding an undercut formation on a circular body in which the formation is moulded in a series of arcuate sections alternating with spaces. According to the method, the moulding core, which produces the formation, is extracted by firstly relatively rotating the body and the core so that the body is expanded radially and then ejecting the body off the core. The method is applicable to the manufacture of closure members and coupling elements.

Abstract: A novel snap on pull off tamper indicating cap and neck configuration for containers, the cap having a top with an annular depending wall on its peripheral edge and seven circumferentially spaced continuous spiral thread configurations on the inner surface of the annular depending wall.

The inner cap includes a top wall having spaced apart upstanding ribs. The outer driver includes a top wall having a pair of top wall segments hinged for pivotal movement to, and being spaced apart from each other by a spacing rib also forming part of the top wall of the driver. Each of the top wall segments initially is secured to contiguous sections of the outer driver by frangible, tamper-indicating tabs, and the top wall segments are moved from a generally horizontal position to a generally vertical position after the tamper-indicating tabs have been broken to form a driving section in the top wall of the driver. This driving section then is directed into the space between the upstanding ribs associated with the top wall of the inner cap by moving the inner cap and outer driver axially toward each other.

The base member has a cylindrical wall with a thread having a varying radial height to complement the position of the jar thread.

Abstract: At the top of a bottle the circumferential bead lying between the cap fastening means and the neck is enlarged in diameter to better meet the enlarged diameter of an oversize cap such as a two piece "child-resistant" cap. The undercut below the bead forming the neck is greatly exaggerated. The circumferential bead is located lower on the top to better fit the extended skirt length of the outer cap of the two piece "child-resistant" cap. A circumferential shoulder is added above the bead to substantially match the skirt length and diameter of a standard cap. Regardless of whether a "child-resistant" cap or a standard cap is used, the plastic shrink-fit band tightly fits about the cap and over and underneath the circumferential bead. The loosening of either "child resistant" or standard cap will force the splitting of the band because the shrinkage of the band below the circumferential bead is considerably greater than the innate circumferential elongation of the shrunk plastic band material.

Abstract: A polyethylene cap, for use with containers, particularly polypropylene containers for containing medical specimens in preservative fluid such as formaldehyde, is provided with a 3-face seal, wherein a rim portion of the container is trapped in sealing, contacting relation on three mutually adjoining faces, whereby any tendency of the container rim to "relax" out of sealing engagement with a contacting face portion of the cap is effectively precluded by the fit and the geometry of the cap seal. In the case of polypropylene, which is susceptible to such "relaxation", the subject cap enables the effective sealing of polypropylene containers so that advantage may be taken of the superior properties of polypropylene in non-reactive, secure containment of possibly contaminated medical specimens in liquids such as formaldehyde, a known carcinogen.

The first connection element additionally includes a second set of internal female threads synchronized with the first set such that the leads of both sets of threads are the same. This second set of internal female threads mates with a corresponding set of external male threads on the mating connection element. Of course, the two sets of threads on the mating connection element are synchronized such that their leads are the same, and, of course, the same as first sets of mating dual synchronized threads. This dual synchronized thread connection has application to any fluid connector and particularly to fluid connectors in wide-variant temperature deviation, high-pressure, and/or mechanical vibration environments.

Abstract: A blow molded, PET container having a unitarily formed body defining a hollow cavity for receiving a product. The body includes a base, a side wall, a neck finish and a mouth. The neck finish, located at the upper end of the container, is formed from substantially amorphous PET that has been thermally stabilized by a heat treating process. A thread is formed on the neck finish to receive a closure cap. The thread is generally in the form of a raised ridge that spirals at least partially around the neck finish. Spaced interruptions divide the thread into thread segments which reduce the PET needed to form the neck finish. The interruptions reduce the residual stresses in the neck finish and thereby reduce the distortion which occurs in the neck finish during hot filling or hot washing of the container.

Abstract: An injection molded threaded cap for use with containers of varying dimensions. The cap of the present invention includes a cover from which depends an integral plug. An auxiliary sealing ring is disposed at the outside base of the plug to compensate for differences between the diameter of the plug and the diameter of the opening to be sealed by the cap. To prevent doming of the cover of the cap, the underside of the cover has shrinkage resistance formations which provide the cap with structural resistance to the effects of shrinkage. The cap of the present invention further includes a ratchet ring having ratchet teeth designed to enhance the tamper-evidency of the frangible ratchet ring. In an alternative embodiment, the cap includes a thread form which reduces the amount of rotation required to install the cap onto a bottle neck.

The novel constructions enable the tamper indicating flexible cap to immediately engage the lead-in ends of the seven circumferentially spaced thread patterns on the exterior of the neck of the container without the heretofore necessary rotation of the prior art caps in order to engage the single spiral thread configuration on the neck of the container.

Abstract: A coupling arrangement connects a container of concentrated cleaning fluid to a dispensing apparatus in a carpet cleaning machine. To facilitate the required fluid connection, the container is fitted with a plug having one port at its center and a second port radially disposed from the center port and positioned within an annular groove concentric with the center port. The distance from the center port to the second port in the plug is equal to the distance between corresponding central and radial ports in the dispenser. When the container is rotated to engage the dispenser and advance it into position, the center port of the plug and central port of the dispenser align since they are on the same axis. The radial port of the dispenser is aligned with the annular groove in the plug, enabling fluid communication with the second port in the plug irrespective of the rotational orientation.
