Abstract: A syringe (10) for drawing blood from a patient, the syringe having a barrel (12) with a restricted free end (12a) and a needle assembly (14) releasably secured to the restricted free end. A plunger (16) is inserted into the barrel through an opposed end (12b), and retraction of the plunger within the barrel, away from the restricted free end, is effective to withdraw blood from the patient when a needle (14a) with a sharpened free end of the needle assembly is appropriately inserted into the patient. The syringe 10 is also provided with an annular needle guard (18) that surrounds the barrel and is slidable with respect thereto between a first position, in which the needle guard does not surround the needle, and a second position, in which the needle guard does surround the needle, to prevent the tip of the needle from injuring a person handling the syringe during times when the syringe is not being used to withdraw blood from a patient.

Abstract: A method for compression molding plastic articles such as closures include a plurality of tools mounted in opposed pairs with the tools of each pair including opposed male and female mold sections. The tool pairs are mounted for motion in an endless path. The tool pairs and associated mold sections are closed during motion in the path for compression a molding charge in the mold cavity formed between the mold sections of each pair, and opening the mold cavity to release an article formed between the mold sections. A latch mechanism is associated with each pair of tools for holding the tools and mold sections in the closed position during motion in the path independent of the mechanism for closing the tools and mold halves. In this way, forces imparted to the mold halves and tools to hold the mold closed are isolated from the machine frame. The latch mechanism is selectively unlatched to permit opening of the mold halves and release of the article compression-molded between the mold halves.

Abstract: A tamper-indicating closure of integrally molded plastic construction that include a base wall having a peripheral skirt with internal threads for engaging external threads on a container finish. A tamper-indicating band is connected to the edge of the skirt by a plurality of circumferentially spaced integral frangible bridges. A stop flange extends from an edge of the band remote from the skirt for engagement with a bead on the container finish. The stop flange has a circumferentially continuous free edge remote from the band disposed in a plane parallel to the base wall. A plurality of circumferentially spaced openings are disposed in the stop flange adjacent to the band for drainage of liquid from between the closure skirt and the container finish. A plurality of circumferentially spaced gussets in the stop flange are at the free edge of the ring, with each gusset being disposed between an adjacent pair of drainage openings.

Abstract: A child-resistant closure that includes a base wall, a peripheral outer wall extending from the base wall, and an inner wall spaced radially inwardly from the outer wall and having an internal thread for securement to a container finish. The outer wall of the closure has diametrically opposed circumferential gaps, and the inner wall extends axially in radial alignment with the gaps in the outer wall for circumferential abutment with lugs on a shoulder of the container. The inner wall is flexible inwardly for clearing the container lugs and permitting removal of the closure from the container finish. The outer wall thus protects the force application area of the inner wall by reason of the fact that such force application area is recessed inwardly with respect to the circumference of the outer wall. The closure resists application of planer force to the removal area of the inner wall, such as by a child biting the closure.

Abstract: A plastic closure and method of making such a closure for a container that has a finish with a top surface portion, a cylindrical outer surface portion, and a curved portion at the juncture of the top surface portion and the outer surface portion. The closure includes a base wall, a peripheral skirt having an inner surface and threads on the inner surface of the skirt for engaging the container. The base wall has an inner planar surface and a compression molded liner is compression molded and bonded on the planar surface of the plastic closure. The peripheral portion of the liner has an outer annular inclined surface. The inclined surface tapers radially inwardly away from the base wall of the closure and is positioned for engaging the top surface portion of the finish and the inner surface of the container and is out of engagement with the outer surface of the finish of the container.

Abstract: A package (10) made up of a blow molded thermoplastic outer container (12) and an injection molded thermoplastic inner container (14) inserted into the outer container through an annular closing receiving finish (18) of the outer container (12). The inner container has a lower major portion (20) of frustoconical configuration and an upper minor portion (22) of cylindrical configuration that is closely surrounded by the closure receiving finish portion of the outer container. The upper minor portion of the inner container (14) has an outwardly projecting bead (24) that is received in an inwardly facing recess (30) of the closure receiving finish portion of the outer container to position a rim (26) of the inner container at an elevation that is slightly above a rim (28) of the closure receiving finish portion of the outer container.

Abstract: A method and apparatus for compression molding plastic articles including closures which includes providing co-acting sets of tools including a first set for moving a core and core sleeve into engagement with a cavity mold on a second set of tooling. An actuator is provided between the first set of tooling and a fixed upper cam. The second set of tooling includes an associated actuator supporting the cavity mold and associated with a lower fixed cam. A nitrogen cylinder in the second set of tooling provides for control of the compression molding force. In a preferred form, a plurality of sets of tooling are provided in circumferentially spaced relation on a rotating turret supported by a central column. A common manifold supplies the pressure at accurately controlled pressure to each of the nitrogen cylinders. A control system is provided for monitoring and changing the pressure.

Abstract: An ink containment and dispensing device for an ink-jet printer is provided with a main reservoir in the form of a flexible pouch, which is typically maintained at ambient pressure. The main reservoir is coupled to a variable volume chamber via a one-way valve which allows the flow of ink from the reservoir to the chamber and prevents the flow of ink from the chamber to the reservoir. The chamber is coupled to a fluid outlet, which is normally closed to prevent the outward flow of ink. However, when the ink supply is installed in a printer, the fluid outlet establishes a fluid connection between the chamber and the printer. The chamber is part of a pump provided with the ink supply that can be actuated to supply ink from the reservoir to the printer. The pump has a linearly acting pumping member and a flexible diaphragm that overlies the pumping member, the diaphragm being impervious to the transmission of oxygen and moisture therethrough to prevent degradation of the ink within the chamber.

Abstract: Lotion pump has a stepped piston telescoping inside a stepped body to define a pumping chamber. The piston has a downward annular wall having inlet and discharge apertures, one above the other, to the pumping chamber. A stem integral with the actuator has a sealing head inside the annular wall which shuttles up and down between positions at which it covers one aperture or the other. Shuttling is implemented by lost-motion between the actuator spout/stem and piston. A spring urges the stem up at all times. The actuator can be turned to lock the head over the discharge aperture by nullifying the lost-motion. Further turning can lock the stem in lockdown position. One-directional turnback can liberate the head and unlock the lockdown. Detents control sequence of unlocking.

Abstract: A squeeze-type container package that comprises a flexible resilient container body and a self-sealing closure assembly mounted to the mouth of the container body. The self-sealing closure assembly includes a dispensing valve of one-piece integrally molded elastic construction having an annular base, an internal wall portion that extends radially inwardly and axially from the base, and a mouth portion that includes a slit opening oriented diametrically of the annular base. Internal stresses within the wall portion bias the slit to the closed position. An annular lip that extends radially outwardly from the valve cooperates with an annular internal rib on the closure for venting the interior of the container body to atmosphere when the container body is released following dispensing of product.
