Abstract: A plastic container for holding liquids, such as syrup, which has a hollow handle completely sealed from the bottle's exterior and interior. The bottle results from blow molding an extruded thermoplastic parison into an unfinished bottle which has a channel running between the interior of the bottle and the hollow space defined by the handle. The air pressure to form the handle passes through this channel. Sealing this channel through the application of ultrasonic heat closes it and provides a handle with an interior volume completely shut off from the exterior and from the inside of the bottle.

Abstract: This relates to the provision of the 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: This relates to the provision of a container having as an integral part thereof a separate pickup tube so that the neck finish of the container has the usual mouth together with a pickup tube mouth. A conventional spray pump has the vent and pickup passage portion thereof replaced by a replacement assembly which will interlock with the container neck finish between the two mouths in a manner to orient the pump with respect to the container. The replacement assembly includes a combined vent and pickup member and a separately formed backup disc which are interlocked relative to one another for selectively positioning the backup disc with respect to the combined vent and pickup member and thus with respect to the pump. The backup disc, in turn, has projecting legs which interlock with the container neck finish. The backup disc has several possible positions with respect to the combined vent and pickup member.

Abstract: This relates to a labeller for applying simultaneously two labels to a dual cavity mold half. The labeller is especially constructed to receive a pair of labels from a pair of adjacent label magazines and then move one of the labels towards the other so as to reduce the overall width of the pair of labels. This permits the pair of labels to be moved between a pair of mold halves within the limited space available and thereafter be rotated for alignment with the dual cavities of the mold half for positioning within the dual cavities. Basically speaking, the labeller includes a support member having mounted thereon a pair of carriers for separate movement towards and away from one another. The carriers are moved such that one normally remains fixed after a label is picked up by pickup heads carried thereby while the other carrier is moved towards the first carrier so as to move the labels together.

Abstract: A valve assembly which may be incorporated in a pump and container arrangement so as to permit the dispensing of liquid from the container when the container is in an inverted position as well as when the container is in its normal upright position. The valve assembly is primarily formed by a disc which has formed as part thereof a valve unit. The valve unit, in turn, is provided with a vent passage therethrough which is normally closed in the inverted position of the unit and a liquid passage which is normally closed in the upright position of the valve assembly. The liquid passage is opened by the weight of the liquid within the container on the ball check valve thereof when the container is inverted.

Abstract: A laminated container blow molded from an extruded parison wherein both the parison and the resultant blow molded container are of a multi-layered construction. Most particularly, the parison is provided with a thin outer gloss coat which maintains the clarity and gloss of the resultant container so as to provide the container with a glass-like appearance. In the forming of the parison, the thin gloss coat is extruded with the remainder of the parison and is bonded to the remainder of the parison by an adhesive layer. The thin outer gloss coat is particularly effective when a relatively thick intermediate layer of the parison is formed of reground scrap containers. Usually the relatively thick intermediate layer is formed of a blend of the reground scrap containers and virgin polypropylene.

Abstract: This relates to an apparatus for applying labels to inner and outer mold halves of a Ferris wheel type blow molding machine. Most particularly, it relates to the substitution of extensible fluid motors for rotary motors wherein a saving of transverse dimensional spacing results, thereby permitting the two label transfer apparatuses to be in closer circumferentially adjacent relation and thereby permitting the proper timing of the applications of labels to relatively short blow molds. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.

Abstract: This relates to the forming of a seal between a container and a top element, such as a fitment, wherein the seal is subjected to a high top loading of a nature wherein conventional gasket materials, such as plastisols, will unduly flow and result in leakage. In lieu of the conventional gasket material, a hot melt material is utilized with the hot melt material being in a flowable state when the fitment is applied to the container and held in place by a mechanical interlock between the fitment and the container so as to cause an extrusion and flowing of certain of the hot melt material wherein the hot melt material functions both as a gasket and as a support to eliminate or restrain movement between the fitment and the container due to top loading. A special dispensing head is also provided for applying a controlled volume of hot melt material to each fitment in a preselected pattern.

Abstract: This relates to a label separator which is operative to separate a foremost label from a stack of labels in advance of such label being picked by a picker so as to assure that only one label is picked at a time and that the other labels in a stack of labels will not be disturbed. One end or edge portion of a foremost label is displaced relative to the remainder of the stack and after a gap has been formed between the displaced label and the next adjacent label in the stack, a blade enters in between these two labels so as to separate completely the foremost label from the remaining labels in the stack. The apparatus which effects the initial displacement has associated therewith a label support whereby the displaced label remains supported in its original alignment for reception by the picker.
