Abstract: An improved dual-seal, wide-surface roller-type dispensing package combination for cosmetics and the like. A wide-surface dispensing roller is held in place in a fitment which is adapted to be attached to the finish portion of a container for the product to be dispensed. The dispensing roller is allowed to revolve within the fitment to facilitate uniform dispensing and application of the contents of the container. The total package is completed by a closure which is adapted to snap into engagement with the container. A primary seal is formed between the dispensing roller and the fitment upon application of the closure. The closure also includes a quantity of resilient material, such as a foamed polymer, positioned to contact the dispensing roller and the fitment to form a secondary seal to prevent leakage of product when the closure is placed into engagement with the container.

Abstract: An apparatus for receiving a single line of containers and grouping them so that a plurality of containers can be delivered to an exit line. The apparatus contains a starwheel arrangement wherein the starwheel is comprised of a plurality of sectors each moveable with respect to each other. Each sector transports a plurality of containers at a constant velocity around an arcuate extent. The sectors and their containers accelerate for a portion of their travel, then stop, whereupon the containers are moved in a radially outward direction to a delivery point upon an adjacent conveyor. The method of receiving containers on a starwheel arrangement and simultaneously ejecting a plurality of containers from the starwheel to an adjacent conveyor is set forth in detail. The containers enter the starwheel in usual singular line fashion and are delivered from the starwheel in groups.

Abstract: A method for controlling the movement of a web of material. The web material advances in a forward direction, thus creating an unsupported loop which characterizes the festoon arrangement of the invention. Web material is advanced into the festoon depending upon the size of the festoon. Web material is withdrawn and returned to the festoon on an intermittent basis independently of the flow of material into the festoon.

Abstract: A loose metal end for forming a seamed can end closure and which includes an annular marginal seaming panel having a radiused outer rim concluding in a curled end underlying the seaming panel and provided with a peripherally interspaced array of radially extending flutes shaped to crest directionally towards the seaming panel. When double-seamed onto a can body, the fluted curled end is folded into a fluted hook end with the flutes cresting radially outward and away from the can body. As thus disposed, the flutes provide preselectively located sites which function to direct such "pinwrinkles" or "pinlips", as may result from buckling compressive forces generated in the hook end during the seaming or crimping operations, to project radially outward and away from the can body.

Abstract: An apparatus for detecting the presence of a gob of molten glass as it enters a cavity in the mold of an automatic glassware forming machine. The detector includes a phototransistor sensor and circuitry for generating a gob detection signal. Two or more detectors can be combined to generate a signal indicating that the last gob has entered a multi-cavity mold so that the forming process can begin. The gob detection signal can also be utilized to adjust the timing of the glassware forming process for differences in the travel time between the gob forming apparatus and the mold.

The polymeric coating composition contains at least two essential ingredients:(1) a rubbery thermoplastic organic polymer; and(2) an organic peroxide or hydroperoxide.

Abstract: Methods for producing improved, thermally-stable polyethylene terephthalate resins are provided. Polyethylene terephthalate resins are provided that can be fabricated into products such as carbonated beverage containers with a minimum of degradation products such as acetaldehyde preferably by rapidly polymerizing a prepolymer from an i.v. of about 0.2 to an i.v. of at least about 0.7.

Abstract: A method is disclosed for enhancing the yield strength and density of polyethylene terephthalate and other similar thermoplastic materials which are susceptible to strain hardening. In the method, the plastic material is thermally conditioned to a temperature within a range conducive to molecular orientation, and then is mechanically conditioned by stretching in a first direction to a length at least about 2.6 to 2.75 times the original length. Thereafter, the plastic material is stretched in a second direction, with strain hardening and strain-induced crystallization increasing drastically substantially immediately upon the initiation of the second stretching operation due to the mechanical conditioning by elongation during the first stretch.

Abstract: This invention relates to the art of coating glassware while the ware is moving through an annealing lehr which is provided with a cooling section near the exit end of the lehr. The cooling section is of the continuous recirculation type providing an arrangement for generally cooling the ware to a relatively even temperature even though the ware is moving through the lehr in multiple rows and columns. The ware is moved through the lehr on a lehr belt which is formed as a webbed belt and constitutes a foraminous conveyor. A lubricious material in the form of a vapor or mist of an organic, nonmetallic coating material selected from the group consisting of polyolefins, fatty acids and their derivatives is injected into the recirculating cooling air in the cooling section of the lehr to thereby form a durable lubricious coating on the exterior surfaces of the glass article. The articles, at the time they are passed through the cooling section, will be at a temperature between 200.degree. F. and 400.degree. F.

Abstract: A method and apparatus are disclosed for controlling crystallization in thermoplastic materials, such as polyethylene terephthalate, which crystallize when cooled from melt temperature to below glass transition temperature after being injected into a mold cavity. When greater amounts of crystallization are desired, a very high pressure is initially imposed upon the material as it cools from the melt temperature, and then the pressure is reduced proportionally to the reduction in temperature so that a nominal pressure is imposed upon the material at glass transition temperature. When a significantly lesser amount of crystallization is desired, an initial nominal pressure is imposed upon the material as it cools from the melt temperature to a predetermined temperature, at which time the pressure is drastically increased.

Abstract: A method is disclosed for molding plastic articles, wherein the method includes the steps of filling a mold cavity at a first station with heated flowable plastic material and then displacing the mold to a second station where the plastic material is cooled under pressure. The apparatus includes a rotatable support for displacing the mold between the first and second stations, a plastic supply means at the first station to fill the molds, and a displaceable rod at the second station for insertion into the mold to apply pressure to the plastic material during solidification cooling.

Abstract: The cooling of glass forming molds is accomplished by providing a plurality of radially spaced passages either in the mold itself or in a mold holder in good heat transfer relationship to a mold insert. The passages extend vertically and may either be completely through the mold or may extend substantially to the lower end of the mold. These passages are radially insulated by the compaction of a particulate material such as 316-L Stainless Steel Compacting Powder, with the compressed material being carefully packed within the passage and in surrounding relationship to a coaxially positioned metal tube. The metal tube provides access for the circulation of a liquid coolant. The thickness of the particular material, its degree of compression and its composition and the relative position thereof with respect to cavities of the glass forming mold, will determine the heat flow characteristics of the mold and/or mold holder.

Abstract: The method and decorated article comprising glassware such as bottles and drinking tumblers is set forth. Halftone printing of a plurality of different colors is employed to produce a composite graphic display on the surface of the glass. Precise alignment is utilized in order to register the halftone printing screens for each color that is deposited on the glass surface. The opaque enamels employed in the decorative process are carefully balanced with respect to each other to obtain the desired color hues. The deposition angles for the alignment of the halftone dots is controlled to minimize the undesirable moire effect.

Abstract: An improved, preassembled ball-type dispensing package combination for cosmetics and the like. A ball is held in place in a fitment which is adapted to be attached to the finish portion of a container for the product to be dispensed. The ball is allowed to move freely within the fitment to facilitate uniform dispensing and application of the contents of the container. The total package is completed by a closure which engages threads on the exterior of the finish portion of the container. The fitment and closure include engaging portions which are adapted to retain the fitment in a preassembled position within the closure for shipping and handling. However, when the combination closure, fitment and ball are placed in engagement with the container finish portion, the retentive engagement between the fitment and the closure may be overcome to allow the fitment and ball to remain on the container when the closure is removed.
