Abstract: A method and system for identifying a molded container such as a glass bottle with its mold of origin, and a corresponding container. Each container has molded therein a plurality of indicia in the form of surface bumps or protrusions extending in an arcuate array at uniformly spaced indicia positions around the container heel perpendicularly of the container axis. The indicia are grouped in sets of two adjacent indicia positions, the sets being of two mutually unique configurations, whereby the sets as a whole identify a binary code associated with the container mold of origin. The method and system for reading such code in accordance with the disclosure contemplate directing a source of diffused light energy onto the container heel, with such energy having an intensity gradient at predetermined orientation with respect to the container axis.

Abstract: A method of making a package, and the resultant unique package, are disclosed. Spaced closure/container co-engaging means, such as interrupted thread segments, are disclosed which define open channels permitting rinsing and drainage of product, contaminants and moisture from the areas normally entrapping same between the closure and neck portion of the container. The invention also advantageously permits use of hermetic sealing structures in production processes not heretofore possible.

Abstract: A plastic container with an integral spout comprising a hollow body, a neck having an outer wall and an inner wall formed with internal threads and a spout connected to the inner wall and extending outwardly of the container. The container is formed by blow molding to form the hollow body, a neck forming portion extending from the hollow body and a spout forming portion extending from the neck forming portion. Thereafter, the neck forming portion is heated and the spout is moved inwardly of the hollow body to reform the neck forming portion into the inner and outer wall. Thereafter, the threads are pressed internally on the inner wall of the neck. Alternatively, the threads may be formed during the blow molding.

Abstract: A plastic closure system for containers or bottles containing liquids under pressure, such as carbonated soft drinks. A liner incorporating a high gas barrier material such as "Eval" in a relatively thin layer is positioned over the end of the container neck. The liner is mechanically designed to have increased sealing forces applied thereto due to the internal pressure acting against the liner. In one embodiment, an overcap mechanically biases the liner over the edge of the container finish with internal gas pressure acting in the opposite direction, thus increasing the sealing force. The other embodiments incorporate a seal that has an annular, enlarged edge that is trapped between the finish and cap with pressure increasing the sealing force.

Abstract: A closure with a snap type hinge cap comprising a first part adapted to interengage with the open neck of a container, a second part forming a cap and an integral hinge interconnecting the first and second parts. Each of the first and second parts comprises a base wall and a peripheral skirt. A pair of hinge straps extends from the skirts and are positioned on opposite sides of the integral hinge. The radial length of the pair of hinge straps is less than the length of the arc through which the second cap part moves to and from and closed position relative to the first part such that the pair of straps stretch to function as springs. The ends of the pair of straps are attached to the skirts radially inwardly of the periphery of the skirts.

Abstract: 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.

Abstract: A method and apparatus for restraining containers against rotation when being moved through operation stations of a cap application process. In the embodiment shown a resilient belt is supported on a star wheel so that a section of the belt subtends an arc of each container receiving pocket in the star wheel. In response to the reception of a container in a pocket the belt section conforms to and wraps around the contour of the container. The belt surface contacting the container exerts a frictional force that is greater than the frictional force applied to the container by guide rails as the star wheel moves the container past the guide rails. The container is thus restrained against rotation within the pocket during the cap application process.

Abstract: 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.

Abstract: A process is disclosed for extruding heavy tubular shaped articles from high molecular weight, high density linear ethylene polymers under shearstress conditions such that the exterior surface of the extruded article would undergo melt fracture. Melt fracture is avoided by coextruding a thin layer of a second ethylene polymer in contact with the high molecular weight, high density linear ethylene polymer and the outer lip of the annular die. The second ethylene polymer has melt flow properties such that it does not exhibit melt fracture at the temperature and shear rate employed in extruding the tubular shaped article.

Abstract: A liquid-tight child-resistant package that includes a glass or plastic container of the wide mouth type (i.e., with a container finish "T" dimension of at least 33 millimeters) and a complementary molded thermoplastic closure that utilizes a separate disk-type liner. The closure which, with the exception of the separate liner, is molded in one piece, has a multiple helical thread start, and each closure thread has a vertically extending shoulder on its upper side. Each complementary container finish thread has a vertically extending shoulder that engages the corresponding shoulder on the closure, after the partial unscrewing of the closure, to prevent further unscrewing of the closure until the closure is vertically depressed on the container finish, against the spring action of the closure liner, to separate the shoulder on the closure thread from the shoulder on the container thread and to thereby permit continuation of the unscrewing of the closure until it can be removed from the container.

There is also disclosed the novel container and cover therefor--the conical label being efficiently applied to the container and easily heat shrunk thereon.

Abstract: A process for forming a doped oxide film suitable for doping a semiconductor wafer substrate material and composite article. A silicon tetra-alkoxide is reacted with a limited amount of water to produce a low molecular weight, soluble polyorganosiloxane. The polyorganosiloxane is subsequently admixed with a reactive dopant source to form a soluble metallosiloxane polymer. The metallosiloxane polymer is coated onto a semiconductor wafer substrate material to produce a metallosiloxane-wafer composite article. The composite article is heated to produce an impurity doped semiconductor wafer suitable for electronic applications.

Abstract: A method for treating hot glass containers that are moved through a treatment zone. The treatment zone is a system which utilizes heated compressed air aspirators rather than electric motor driven blowers to cause a treatment vapor laden air contained in chambers to be propelled across the width of the ware conveyor from both sides at adjacent, horizontally spaced, points in the conveyor length. The resultant streams of heated air and vapor laden air will impinge on the containers carried on the conveyor and are of a size to cover the container height to about the shoulder. The vapor and air that passes the containers from one direction is captured and fed to the chamber for feeding in the other direction. Thus the vapor laden air is recirculated from side to side with additional concentrated treatment vapors introduced to maintain a certain level of tin or titanium in the vapors so as to produce the metal oxide coating on the containers.
