Abstract: A plastics weld pourer component having child-proof properties for attachment by welding to a container component of film-like plastics material, includes a tubular body portion defining a through passage having axially spaced ends. A plurality of welding ribs is formed integrally on the outer periphery of the body portion near one axial end of the through passage. Furthermore, a cap member is integrally formed on the body portion near the other axial end, said cap member sealing the through passage at one end. The cap member is attached to the body portion through a weakened portion which is adapted to break when a rotational force is exerted by hand on the cap member. The dimensions of the cap member relative to those of the body portion are made such that the cap member can be placed on the body portion for repeatedly sealing the through passage after it has been separated from the body portion.

Abstract: A hermetically sealed, molded thermoplastic dispensing container is provided which includes a nozzle having a resilient and unitary annular bead about the periphery thereof. The nozzle is sized to receive the hub of a dispensing assembly in a mating relationship and the bead provides a secure friction fit and liquid seal between the hub and the nozzle. The method of forming a container with a nozzle having such a bead includes the use of seal molds having a groove conforming to the shape of the bead and a vacuum passage in communication with such groove and the step of creating a vacuum through the passage and the groove to pull a portion of a parison into the groove to form the bead.

Abstract: An aperture forming structure, which when attached to or integrally formed in dispenser packages for flowable substances allows reclosure and single or multiple uses. The aperture forming structure includes a break away tip member of thermoformable plastic. The break away tip includes a hollow protrusion from a surface. The intersection of the hollow protrusion and the surface is a fault line. Rupturing of the fault line creates an aperture from which the contents of the dispenser package may exit. A cap may be integrally formed with the aperture forming structure and detached for protecting the hollow protrusion or for closing the aperture created when the fault line is ruptured. The aperture forming structure can be made by heating a relatively stiff substantially flat thermoformable sheet of and then stretching the sheet to create a first and a second hollow protrusion in a tiered configuration. A rupture line is placed at the intersection of the first and the second protrusions.

Abstract: A tamper indicating bridged fitment is provided having an annular flange and an upwardly extending cylindrical side wall. Said fitment has a tamper indicating feature which is comprised of a bridge connected to the top edge of said upwardly extending cylindrical side wall by frangible webs. The tamper indicating bridge additionally has a slot formed longitudinally therethrough, said slot receiving a tab extending upward from a plug. The plug is a separate element which is comprised of a tab and a top wall and additionally has a downwardly extending cylindrical seal wall which acts to seal the fitment. Once the tab is inserted through the slot in the tamper indicating bridge, the fitment may only be opened by breaking the frangible tamper indicating webs connecting the bridge to the fitment side wall. Once the webs are broken, the plug may be removed by the tab and the bridge is thereby disconnected from the fitment.

Abstract: A closure (10) is shown including a U-shaped handle (27) integrally connected to a cap (22) in turn integrally connected to the end wall (18) of a bottle (12) to seal the opening (20) formed therein.

The spout has a cylindrical outer tube (13) to be placed outside a package (15) and a base (12) to be bonded to the inner surface of the package (15). The cap (20) is separably connected to an extremity of the cylindrical outer tube (13) coaxially with the cylindrical outer tube (13) in a position in which the cap (20) is pushed into the cylindrical outer tube (13).

Abstract: A plastic tube with an integral finish and a twist off tab are blow molded. The twist off tab is connected to the finish of the tube by an annular groove forming a line of weakness. The tab is formed by the closing of mold halves about an extruded parison to form a flat twist off tab connected by a thin membrane to the exterior of the finish. The tab is then blow molded to form the tube. After the mold halves are opened, the twist-off tab is trimmed to provide the finished tube. The tab is formed by a conventional blow molding process without the need of a secondary operation. A plurality of blow molded corrugations are provided between annular blow molded ribs on the finish and provide added strength to the finish to facilitate removal of the tab.

Abstract: A hermetically sealed container is provided with a dispensing nozzle terminating in an aperture surrounded by locking lugs. A removable closure portion unitary with the dispensing nozzle and delineated by a frangible web that circumscribes the opening is provided as well so that the closure portion may be severed from the cap portion at the frangible web. An apparatus for fabricating such container is provided which includes a main mold assembly for molding the container body and dual seal mold assemblies for molding the container cap portion and container closure. The main seal mold assembly includes a top surface having a knife edge and an annular cavity. After the main seal mold assembly is closed during the molding process, a forming assembly including a mandrel is extended through the parison into abutting contact with the parison over the top surface of the main seal mold assembly.

Abstract: An ampule of plastic can have liquid removed from the ampule by an injection member having a conical member at its end. The conical member is introduced into the ampule neck. At least one longitudinal passage is arranged peripherally around the ampule neck inside surface and is displaced from alignment with the longitudinal middle plane of the ampule defined by markings.

Abstract: A container-closure assembly made of a soft plastic material comprising an elongated tubular member having a hollow nozzle, the bore of the nozzle at the tip end defining a discharge opening, a cap member connected at one end to the tip of the nozzle by a fracturable bridge connection and having a outwardly flared skirt projecting from said one end, a hollow finger disposed interiorly of the skirt, and the opening of said finger adjacent said nozzle being of a smaller diameter than the discharge opening in the nozzle to define a stepped configuration.

Abstract: A plastic bottle includes a bottle body, a neck constructed on the bottle body and a head constructed on the neck. A separation area is provided between the head and the neck. On the neck and/or between the neck and the bottle body at least one additional separation area is provided.

Abstract: An improved closure insert is provided for throat region of a blow-molded container. This closure insert is provided with a rough perimeter and is permanently molded into the container throat region during container formation from a parison. The resulting seal resists loosening or disturbance when off-axis force or torque force is applied to the closure insert during container opening.

Abstract: An internal fitment has a bottom peripheral flange adapted to be ultrasonically welded or otherwise attached to a panel of a paperboard carton surrounding a hold in such panel. Above the flange is a spout which converges upwardly and has a cylindrical external locking bead. Above the spout is an outward slanted tear band and above the tear band is a reclosure cap having a top, a depending skirt formed with internal interrupted beads and a plug. The tear band is connected to the spout and cap by thin horizontal tear lines. A finger grip tab extends outwardly of downward with respect to the tear band so that the consumer may conveniently grip the tab, pulling it circumferentially around the spout to separate the tab from both spout and cap. The cap is dimensioned so that the skirt fits over the outside of the spout, the beads detachably locking under the locking bead. The plug seals against the inside of the spout to prevent spillage.
