A cathode ray tube faceplate press having an indexing table rotatable around a column normal to the table and having circular array of female molds concentric with the column. Index speed of the table is optimized by a barrel cam drive cut to provide smooth acceleration and deceleration which can be tolerated by the molten glass in the molds. A cam dwell precisely registers the table work stations avoiding the need for register pins and the delays they introduce. Acceleration and deceleration peak at about the one-eighth and seven-eighths position of the drive cycle following a generally sinusodial form.

Apparatus and method for inspecting the finish of transparent containers, particularly glass containers, which include facility for directing diffused light energy laterally through the container finish as the container is rotated about its central axis. A camera includes a plurality of light sensitive elements disposed in a linear array angulated with respect to the container axis to view the external and internal finish wall surfaces, the latter through the open container mouth. Individual elements of the camera linear array are sampled by an information processor at increments of container rotation, and corresponding data indicative of light intensity at each element is stored in an array memory as a combined function of element number and scan increment. Such data is compared following completion of container rotation to standard data indicative of acceptable container finish, and a reject signal is generated if such comparison exceeds an operator adjustable threshold.

A tamper indicating hermetically sealed package comprising a container having a neck with an opening and a closure. The container includes a first annular bead at the upper end adjacent the opening and a second annular bead spaced axially from the first annular bead and having a greater diameter than the first bead. The closure is made of plastic and comprises a base wall and a peripheral skirt. The base wall includes an annular bead on the internal surface thereof and the peripheral skirt includes an interrupted annular bead spaced axially from the base wall. A sealing gasket is cast in situ in the channel defined by the annular bead on the base wall and the peripheral skirt and extends to the interrupted annular bead on the skirt. A tamper indicating band is connected along a weakened line to the peripheral skirt and includes an interrupted annular bead that is adapted to engage the second bead on the container.

A vacuum indicating thermoplastic closure for a container for the packaging of a vacuum-packed product, the top panel of the closure containing a circular inner portion which is connected to an outer annular portion by an inner annular portion with a circular hinge on the outside of the closure along a first interrupted line between the circular inner portion and the inner annular portion and another circular hinge on the inside of the closure along a second interrupted line between the inner annular portion and the outer annular portion to permit the circular inner portion to be moved relative to the outer annular portion from a first position which indicates the presence of a vacuum in the container to a second position which indicates the absence of a vacuum in the container without developing substantial tensile stresses in the top panel of the closure when the circular inner portion is in either such position, except for compressive stresses in the bridges formed by the interruptions in the first interrupted line and in the second interrupted line when the circular inner portion is in the first position, which compressive stresses assist in positively moving the circular inner portion from the first position to the second position upon the loss of vacuum in the container. Also, a package consisting of a container, a vacuum packed product contained in the container and such a closure in sealing and closing engagement with the container.
摘要:
A cylindrical vacuum drum for carrying a label held to its surface by vacuum past an adhesive applying roll to a position where the label will touch a container and the container will be rolled along the drum surface to thereby apply the label about the container. The drum is formed of metal and is mounted for rotation about its vertical axis. The drum has a rubberlike covering thereover with at least two raised areas in the cover, which underlie the leading and trailing edge of a label that is at a greater radius than the rest of the surface. These are the areas which serve to press the label against the adhesive roll or solvent applying gravure roll. These areas have very slightly depressed zones forming slight steps just in advance thereof with a row of vacuum ports extending through the cover at the base of said steps to effectively hold the leading edge of the label down and allow the trailing edge to bend upwardly away from the outer surface of the drum. Additionally, replaceable insert strips are provided for the trailing edge of each raised pad that underlies the trailing edge of the labels so that this area which exhibits the most wear can be replaced rather than require replacing the entire drum.
摘要:
A system for metering and dispensing product from a container is illustrated in an embodiment in which a closure, for a container having a neck portion, has a discharge port with a spout pivotally supported in the port. The spout has a top wall which closes the port and has spaced opposed depending side walls which extend into the container when the spout is in the closed position. The side walls have matching curvilinear edges. A valve member is supported in the container so that the spout can be moved into and out of registration with it. The valve member has a curvilinear surface that conforms to and mates with the curvilinear edges of the side walls when they are in registration to define a closed dispensing chamber having a predetermined measure of product therein. The spout is filled when out our registration with the valve member.
摘要:
A method and apparatus for maintaining critical alignments between the neck of a container and closure application stations. The embodiment disclosed illustrates apparatus for handling containers during the process of filling and applying closures to the filled containers. A star wheel with outwardly opening container body pockets and a container guide rail receives filled containers as they are descending from a filling position, and moves the containers through closure pickup and pre-tightening apparatus to a closure applicating machine. A container neck guide receives and guides the necks of filled containers along a predetermined path through the pickup and pre-tightening stations. The neck guide, pickup and pre-tightening stations are supported on the same structure to insure that the predetermined alignment positions are maintained.
摘要:
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.
摘要:
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.
摘要:
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.
