A method of producing a container and a closure comprises blow molding a body comprising a container portion and a closure portion joined together, and separating the closure portion from the container portion. A container and/or a closure produced according to the method are also disclosed, as well as an intermediate product for producing a container and a closure.

Simultaneously blow molded container and closure

An apparatus (') and a machine () for reforming a portion of a plastic package () using induction heating. The apparatus and machine comprise a frame () engaging the plastic package and a workpiece support () having an electrically conducting workpiece (). An induction workhead () provides an alternating current power supply to an induction element (). The induction element is positioned proximate the workpiece of the workpiece support and heats the workpiece via induction. A mechanism () positions the plastic package proximate the heated workpiece so that the workpiece transfers heat to the portion of the plastic package thereby softening the portion. A forming die () supported on the frame engages the portion to reform the portion. Also provided is a process of using the apparatus and machine to reform a portion of a plastic package using induction heating.

In blow molding, each mold has two or more cavities, each respectively fed by two or more parisons. Each cavity fed by a separate parison may itself include two or more article cavities aligned with its parison.

Multi-parison/dual cavity wheel blowmolds

A squeezable tube-shaped plastic container ( ) having a one-piece construction formed by extrusion blow-molding techniques. The container ( ) has a retractable end wall ( ) which is positionable into an outwardly projecting position and an inverted position. The end wall ( ), as blown, is in the outwardly projecting position and is thereafter inverted so that a tamper indicating covering ( ) can be attached to the end ( ) of the container ( ) thereby sealing the end wall ( ). The inverted end wall ( ) permits the container ( ) to be free standing on the standing ring ( ). In use, the flexible sidewall ( ) of the container ( ) is squeezed to snap the end wall ( ) from the inverted position to an outwardly projecting position to enable ready access to a dispensing opening ( ) on the end wall ( ). An efficient and cost effective method for forming the container ( ) and an intermediate article ( ) formed during the method are also disclosed.

Extrusion blow-molded squeezable tube-shaped container and method for making same

At least one blow-molded plastic container and one compression molded lid are simultaneously produced in a blow mold. Preferably, the method and apparatus utilize a mold capable of simultaneously receiving a pair of extruded parisons. One of the parisons is utilized to produce a pair of aligned container bodies and the other of the parisons is utilized to form a pair of aligned closures. In this manner, a container and closure combination can be manufactured having perfect color matching and can be readily recycled in its entirety. In addition, the method and apparatus according to the present invention significantly reduces tooling costs and required machine capitol.

A blow-molded plastic container ( ) providing enhanced top loading capability. The container ( ) has an inner peripheral surface ( ) on which a plurality of integral, solid, inwardly and longitudinally extending ribs ( ) are formed. Preferably, the ribs ( ) extend throughout the entire container inner surface ( ) from the top edge of the finish ( ) to a mold parting line ( ) on the base ( ). A method and apparatus for making the container ( ) is also disclosed.

A blow-molded container (,) having a closure flap (,) formed of compressed material (,) integral with the container (,). Preferably, the container body (,) has a normally-closed fill port (,) and a dispensing port (,) which can be selectively opened and closed by the closure flap (,). The closure flap,is provided with multiple hinges (,) to allow the closure flap (,) to fold reversely upon itself and to allow the dispensing port (,) to be opened and closed while the fill port (,) remains closed.

Integrally blow-molded container and closure

A unitary blow-molded hand-held plastic container having improved pouring capability without requiring separate pour spouts is disclosed. The neck has a pair of opposed panels that are pinched inwardly below the finish of the container to afford precise control during pouring.

Pinch neck pour spout container

A blow-molded plastic container manufactured from a homogenous mixture of a plastic resin, a calcium carbonate filler, and a blowing agent in specified amounts. The filler reduces the overall material costs, and the blowing agent reduces the specific gravity of the mixture to enable the container to be recycled utilizing existing floatation tank recycling equipment.

Cost-effective environmentally-friendly blow-molded plastic container

A fitment for use on a container for dispensing liquids. The fitment provides a pouring spout and a drain back function and is secured within the container finish. The container finish has a neck with a rim and a shoulder. The fitment has an outer wall with upper and lower ends and with a frustoconical shape to ensure that a portion of the outer wall frictionally engages the container finish when the fitment is inserted into the container finish to prevent the fitment from being inserted completely through the neck of the container. An annular bead extends outwardly from the outer wall a spaced distance from the upper end of the outer wall so that when the fitment is engaged in the neck of the container, the bead is positioned directly under the shoulder of the neck. Multiple bands of sealing engagement are created between the fitment and the container fitment to ensure a leak-free connection.

Plastic container dispensing fitment

A wide-mouth, plastic container and lid. A leak-resistant seal is disclosed that withstands the stresses and strains imposed due to rough handling. An easily removable, tamper-evident lid is disclosed.

Blow-molded wide mouth plastic container and injection-molded lid

An integral blow molded bottle having a neck, a thread surrounding the neck and a collar at the top of the neck. A circumferential flange is provided on the outside of the top of the collar and a support column is provided on the inside of the collar for limiting threading of a cap down on the neck. A circumferential groove is formed in the outside of the collar to prevent bottoming of the flange by a cap threaded onto the neck.

Plastic bottle having a linerless closure with collapsible flange and

A blow molded container having a break-away measuring and dispensing cup. In the disclosed embodiments, the cup is formed during molding from a web extending along a parting line of the blow-molded container body. The web has a weakened region which detachably connects the cup to the container. The cup can be re-attached either on the container or its cap in a non-use stowage position.
