Abstract: A dispensing package includes a bottle, made of a blow-moldable plastic and having a neck finish, a pouring spout and a closure. An undercut groove in the interior of the neck finish holds a bead on the spout. The spout may have a pour-back design. Threading the closure onto the neck finish engages a top surface of the neck finish just above the groove with a closure-mounted seal. The groove may result from molding the neck finish against a pin which is withdrawn from the neck finish while the plastic is still warm but has enough plastic memory to result in groove definition following pin removal. The bead of the spout may be press-fitted into the groove while the plastic is warm so that cooling-caused shrinkage firmly locks the spout in place.

Abstract: Method of forming a pour spout portion of a blow molded plastic bottle with a dripless lip. In one form, the terminal end of the pour spout is internally reamed at an angle so as to terminate in an exterior sharp edge, after which the resultant tapered end portion of the pour spout is engaged by a rotating tool which frictionally heats the plastic engaged thereby and progressively turns over the sharp edge through an angle on the order of 180.degree. to provide the desired dripless lip. In another form, the pour spout portion of the container neck finish is provided with an integrally molded outwardly directed hollow rib which lies in a sloping plane. The rib extends only partially about the circumference of the pour spout. The pour spout is then trimmed at an angle to the axis of the pour spout and parallel to the plane of the rib so as to provide for a pour lip of limited circumferential extent and which pour lip, depending upon the plane of trimming may terminate in a sharp dripless lip.

Abstract: Methods and apparatus for blow-molding hollow articles from open-ended tubular bodies of thermoplastics material include dimensionally expanding the open end of the tubular body to accomodate a blow pin plate of preselected dimension and/or geometry. The expanded open end of the tubular member will thus be closed by the blow pin plate. Subsequent introduction of pressurized fluid (e.g., air) into the tubular body through the blow pin plate will cause the tubular body to conform to the female cavity which envelops the same. In such a manner, hollow articles having relatively large sized and/or irregular shaped openings may be fabricated utilizing blow-molding techniques.

Abstract: A multi-layer drawn polyester bottle has a neck portion having an opening on the top end and a fitted or screwed part on the periphery, a bottom portion formed by fusion bonding and closing of a pipe and a barrel portion biaxially molecularly oriented by draw-blowing of the pipe.

Abstract: A container (30d) of polyethylene terephthalate or similar thermoplastic material has a container body (32d), a mouth portion (37d) and a central bottom part (34d). The central bottom part consists of chiefly amorphous and/or thermocrystallized material and forms a bulge directed towards the interior of the container. A ring-shaped or band-shaped standing surface (36d) is arranged adjacent the transition of the bottom part into the container wall (32d). Adjacent to the standing surface the container has a circumferential area of material (35d) which by stretching and/or reshaping has undergone flow and by heating has acquired built-in stresses which tend to contract it. The surrounding circumferential area of material prevents the inward bulge of the central bottom part from straightening out and/or turning inside out when the pressure in the container is increased and/or when the temperature of the container material is raised.

The parison is axially stretched by a stretch pin to pull out the heated plastic material adjacent the profile to a thinner cross section. This allows to obtain a considerable saving of weight of the plastic material.

Abstract: This invention relates to a blow pin assembly for use in extrusion blow molding processes to yield thermoplastic containers having a dripless pour lip. The dripless pour lip is achieved by forge forming a portion of the neck moil, which moil is characteristic of extrusion blow molding processes. The shape of the pour lip is dictated by a downwardly facing groove carried by a cutter collar which is part of the blow pin assembly. This groove coacts with a split annular anvil carried by the split blow mold to achieve the necessary forge forming of the container lip. The cutter collar also achieves removal of the excess neck moil material by a shearing action achieved between the outside edge of the groove and the split annular anvil.

Abstract: A blow molding machine is provided with an external center pin so that blowing is accomplished without introducing a mechanical or rigid member within the preform and/or bottle. To do this, the blowing is done by introducing a fluid, preferably a gas such as air, into the preform to expand it. Outside of the preform, meanwhile, is the subject center pin or center rod which is located on the preform center line (axis) and near the middle of the preform bottom. The rod receives a gate disposed centrally on the bottom of the preform when the preform is expanded by the entering fluid. In this manner, the center part of the bottom of the preform is engaged by the center pin which thereafter keeps the preform on center as the blowing action continues. A process is disclosed of blowing using a compressed fluid alone inside the preform to expand the preform axially against the bias of an external resiliently biased center pin.

Abstract: A method and apparatus are disclosed for transferring blanks, plastic parisons or other articles to be molded in a sealed cavity.

Optional biasing means may be included to hold the mold sections sufficiently close together to hold the blank in the mold cavity as the mold sections move from the first station to the second station. A clamp, or other pressure applying means, exerts a final closing pressure on the mold sections at the second station for molding the blank under pressure. The clamp is stationary in relation to the first and second stations so that the mold sections can move relative to the clamp along the second axis.

Abstract: An article (11) of thermoplastic material is moulded from a parison (10) in which certain parts (17,16) of the parison are re-formed while other parts (13,12,20) retain their shape. A difference in pressure is applied to the wall of the parison during the re-forming process. Material in the parison is also moved in the direction of those parts of the parison which are to be re-formed, whereby attenuation of the material may be avoided entirely, if so desired, also in those parts which are to be re-formed. The invention enables the parison for a bottle to be re-formed to an extent which is small by comparison with the thickness of the material, for example the so-called "neck support" ring and the so-called "pilfer proof" ring, starting with a tube of oriented material. In a device for the application of the invention the elements (22,21,25) are in contact with the parts (13,12,20) of the parison.
