A method and apparatus for placement of labels within the blow molds of an injection blow molding machine. The injection blow molding machine comprising a turret having plurality of circumferentially spaced surfaces, each of which supports a plurality of spaced core rods, a plurality of injection molds at an injection molding station for forming a plurality of preforms, and a plurality of blow mold sections at a blow molding station which close about the preforms so that the preforms can be blown outwardly against the confines of the mold to form hollow plastic articles. The blow molds include movable bases exposing the interior of the blow molds when the blow molds are closed about preforms on the core rods. A positioning apparatus positions a plurality of labels at the blowing station and a plurality of cylindrical vacuum mandrels are rotated to pick-up the labels and thereafter the mandrels are translated to deliver the labels to the blow molds through the open bottoms after which the mandrels are retracted, the mold bottoms are closed and the hollow articles are blown in the molds with the labels on the outer surfaces thereof.

In-mold labeling of injection blow molded hollow plastic articles

A hollow plastic bottle comprising a bottom wall, a side wall about which a label is wrapped and a neck with a finish for receiving a closure. The bottom wall is shaped to withstand drop loads and comprises a central portion, a first annular portion extending outwardly and downwardly from the periphery of the central portion, a second curved portion extending from the periphery of the first annular portion and having a concave inner surface and a convex exterior surface, and a third annular portion extending from periphery of the curved portion upwardly and outwardly to an annular shoulder portion connected to the side wall of the bottle.

Hollow plastic bottle with wrap-around label

A label magazine comprising a tray for supporting a stack of labels and having a device at one end for yieldingly urging the labels toward the other end of the tray and a plurality of circumferentially spaced spring fingers positioned at the other end of the tray about the labels, each finger including an axially extending portion and an inwardly extending portion engaging the outermost label of the stack. Each finger is mounted so that it can be adjusted to move the finger inwardly of the label and accomodate variations in the size of the labels.

Label magazine

Apparatus for applying labels in the molds of a plastic blow molding machine of the type wherein a plurality of sets of molds are mounted on a wheel rotatable about a horizontal axis and the molds are moved toward and away from one another to enclose a parison and the parison is then blown to the confines of the cavity between the mold sections which comprises removing labels successively from one or more magazines, depositing the labels on an endless conveyor which transports the labels to a position adjacent an open mold and laterally transferring the labels from the conveyor to a position within the molds such that when a mold closes about a plastic parison and the parison is blown, the labels become adhered to the blown plastic bottle.

Apparatus for applying labels in the molds of a plastic blow molding

A method and apparatus for delivering labels to the blow molds and removing blown containers with the labels thereon from a blow molding apparatus wherein the apparatus precludes access to the upper or lower ends of the molds. A carriage is reciprocated horizontally between a position externally of the blow molds and a position within the blow molds. The carriage supports pick-up heads that pick up labels from magazines, deliver them between the mold halves and deposit them on the mold halves. The carriage also supports container removal devices that engage the blown containers with the labels thereon and remove them from a position between the mold halves.

Apparatus for delivering labels to blow molds of a plastic container

In the making of hollow plastic articles wherein a label is positioned in each of a plurality of spaced partible molds, a preform is positioned in each set of partible molds and the molds are closed and the preform is blown outwardly into the confines of the mold to apply the label to the resultant hollow plastic articles, the method of handling the labels which comprises successively removing labels from a label magazine and positioning the labels in an array which corresponds in spacing to the spacing of the sets of molds, simultaneously moving said labels in the array from the first position to a second position within the open partible molds and depositing the labels in the molds. The apparatus comprises a magazine for supporting labels in a stack, an endless belt transfer device positioned adjacent the magazine, means for indexing the belt in predetermined spaces corresponding to the spaces of said molds, means for successively removing a label from the magazine and depositing it on the conveyor, the spacing between the labels on the endless transfer conveyor corresponding to the spacing between the sets of molds, and means for removing the labels simultaneously from said endless transfer conveyor and delivering them between the open partible molds.

Apparatus for applying labels to blow molded articles

In the forming of an article by blow molding a parison into conformity with a cavity defined by a partible a method and appartus which comprises positioning a label of flexible material on each section of the mold, each label having a width in a circumferential direction such that a portion of one axial edge of each label extends beyond the side edge of the cavity forming portions of the section of the mold and the other axial edge, moving the mold sections toward one another so that they close and define the mold cavity, deflecting the edge of each label radially inwardly before the molds close such that as the molds close the deflected edge will overlap with an adjacent edge of the adjacent label, and blowing the parison into conformity with the cavity such that the edges of the two labels overlap and register to define a continuous label about the article.

Labels to blow molded articles

A system for the handling of lightweight plastic containers into and through a case-packing operation wherein the containers are moved in a single line onto a conveyor where a diverting guide will move the containers into a multiple lane receiver. The multiple lane receiver is rotatable about its longitudinal axis through a 90.degree. angle, either with the container bottoms facing to the left or facing to the right. On the left side of the receiver, a carton-handling arrangement tips a carton toward the containers which are held in the receiver. A pusher mechanism moves the containers, as a group, from the receiver into the carton, and the carton is then returned to its original position.

Method and apparatus for packing plastic bottles

A batch process for recycling plastic container scrap is disclosed comprising the steps of reducing a container bearing an externally disposed label to granules, agitating the granules in hot water to remove the label material portion from the plastic portion, separating the hot water and label portion from the plastic granules, filtering and recycling the hot water into the batch while separating the waste label residue, remixing and reagitating until substantially all of the waste label residue is removed. Subsequently, the plastic granules are floated over a weir and collected in a dewatering station with the hot wash water recycled into a hot water reservoir. A major portion of the wash water is removed from the granules in the dewatering station. Substantially all of the residual wash water is removed in a drying station.

Process for recycling plastic container scrap

There is disclosed a method for attaching a polyethylene sleeve label to a polyethylene bottle, the label having on the outer surface thereof means for absorbing heat in local, discrete areas of the label at a rate greater than that of other areas of the label; and means for welding the label to the body at the junction of the outer surface of the body and the inner surface of the label, adjacent the local heat-absorbing areas.

Apparatus and method for welding a polyethylene sleeve label to a

There is disclosed an apparatus and method for attaching securely a polyethylene sleeve label to a polyethylene bottle, the bottle having a neck, a body and a bottom. The apparatus comprises means for holding the polyethylene bottle with the sleeve label, and welding means for welding the label to the body of the bottle to prevent loss of the label, the welding means including heating means located away from the label and not in contact therewith.
