Abstract: A tamper indicating package comprising a container having a neck with an external thread and a closure comprising a base wall and a peripheral skirt having an internal thread engaging the thread on the container. The closure includes a tamper indicating band connected to the free edge of the skirt along a weakened line and having an internal bead adapted to engage an annular rib on the neck of the container below the threads. The tamper indicating band includes indicia which is contrasting to any indicia on the closure such that when the closure is removed from the container and reapplied to the container, the absence of the indicia on the bottom of the closure will indicate that the tamper indicating band has been severed from its attached relationship to the closure.

Abstract: Sleeve fabricating apparatus for fabricating cylindrical sleeves from rectangular blanks of a heat-shrinkable thermoplastic material and for transferring the sleeves, in succession, to frustoconical mandrels of a cup-forming machine. The sleeve-fabricating apparatus has a plurality of cylindrical mandrels that are rotatably affixed to a rotary turret. The sleeves are fabricated from rectangular blanks that are cut, in succession, from a web of indefinite length as the web is being unwound from a coil at an unwind stand. Each blank is longer than the circumference of the cylindrical mandrel to which it is applied, leaving ends of the blank which overlap, and the overlapped ends are joined to one another by heat-sealing. Cups are formed by the cup-forming machine, each cup being formed from one of such sleeves and a disc. The sleeve fabricating apparatus also includes a disc forming mechanism for forming discs and applying the discs, in succession, to the cylindrical mandrels.

Abstract: Five embodiments of a tamper indicating molded plastic band that locks over a ledge on the closure and beneath a flange on the container. The cylindrical band is molded with continuous locking rings or interrupted tabs joined adjacent the top end bottom edge thereof and which extend inwardly and generally toward each other to form mechanical locking members. Depending upon the particular arrangement of the locking rings on the tamper indicating band, the band would be applied to the closure before or after threaded application to the container. The band may be used with a plastic or metal closure and with a plastic, metal or glass container having a threaded neck and outwardly extending radial flange therebelow beneath which the ring or tab will lock.

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 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: A machine erectable compartmented multi-cell one-piece container partition formed from a unitary blank of foldable paperboard to separate articles in a box. A rectangular, planar, horizontally-disposed blank of foldable sheet material is cut and folded to provide vertically disposed flaps or segments of single thickness forming separator walls defining a plurality of separator cells (preferably twelve) to separate segregated articles at their contact points, with the blank having a length and width not exceeding inside box dimensions. Each of the vertically disposed segments is folded from the blank along a hinge line disposed intermediate the top and bottom ends of each segment, whereby the segments extend above and below the plane of the blank to form walls of the separator cells.

Abstract: Concentrated aqueous solutions of at least about 20 wt. % of finely divided silica and at least about 15 to 20 wt. % urea are coated on corrugated board effectively and easily by sponging, the coating having non-skid properties, the quality of printing being enhanced and warp being reduced.

Abstract: Jaws for receiving, holding, and rotating containers around a turret periphery are provided, the jaws being easily and efficiently adjusted to accommodate various sizes of containers, such as, for instance, oriented plastic carbonated beverage bottles in sizes ranging from about 1/2 liter to about 2 liters. The same original center line for the container is maintained.

Abstract: A tough, heat shrunk, wrinkle-free coextruded multilayer sheet sleeve label for containers, the sleeve especially adapted for solvent sealing although it can be sealed by ultrasonic, hot air and heat sealing, the sheet being a tough skin layer/brittle polystyrene foam layer structure, the skin layer comprising a polyolefin, a block copolymer of butadiene and styrene as a compatibility agent, and polystyrene, the compatibility agent providing limited adhesion to preserve the toughness of the skin layer for the total label structure, and the polyolefin providing the skin layer with the desired shrinkage rate and limited shrinkage when the label is heat shrunk.

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: A dispensing closure valve comprising a stem having an annular wall defining an opening. The dispensing closure valve includes a closure including an outer annular wall, an inner annular wall and an integral portion connecting the inner and outer annular walls at the outer end of the closure. The inner annular wall has a transverse wall. The inner wall and transverse wall having a sufficiently thin cross section such that they will flex. A tab integral with the transverse wall extends outwardly from the inner surface thereof for flexing the transverse wall extends outwardly from the inner surface thereof for flexing the transverse wall and inner wall to permit fluid to flow from the opening of said stem. Interengaging portions are provided between the tab and the closure body which are operable upon movement of the tab to open the valve to hold the valve in open position.

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.
