Abstract:
An energy output measuring device including a main body having a light reflecting exterior and a window portion formed in the main body and produced from infrared-reflecting glass. At least one visible light sensor is disposed adjacent the window. The energy output measuring device is configured to pass through a heating device. An energy output of the heating device is determined from measurements taken by the heating device.
Abstract:
A handheld torque measuring meter adapted to measure the downward thrust and torsional force required to apply or remove a screw type closure from the threaded neck or finish of an associated container is disclosed, the handheld meter having a first portion graspable a user, a member adapted to receive a portion of a closure of a container, means connecting said main body to said member including a load cell, and a means for displaying a measurement adapted to receive the output signal from the load cell and indicate one of the torsional force and the linear force required to effect a movement of the closure relative to the associated container.
Abstract:
A method and an apparatus for monitoring the production of blow molded plastic containers (20) includes a columnator (26) and sound detector (24) responsive to a defect sound of pressure fluid escaping from a container being formed in a mold cavity (14). The columnator is effective to filter the defect sound from ambient noise. An output signal generated by the sound detector is processed to generate a control signal used to reject a defective container. Preferably, the open end of the columnator is positioned between 20° and 150° from the preform loading station in a rotary platform (12) blow molding machine.
Abstract:
A process for extending the shelf life of a carbonated beverage within a plastic bottle comprises placing the carbonated beverage in the plastic bottle at a temperature less than about 72.degree. F., maintaining the temperature of the carbonated beverage at less than about 72.degree. F. for a time sufficient to convey the plastic bottle to an unrefrigerated, insulated container, and inserting the plastic bottle into the container.
Abstract:
An improved plastic container of the type suitable for containing carbonated beverages. The container is provided with a central section, an upper section including a typically threaded neck portion, and a lower end or base section typically including radially arrayed concave foot portions to support the container in an upright position. The horizontal cross-section of the central section manifests the configuration thereof to include a plurality of juxtaposed generally flat panels which upon pressurization of the container tend to blend together to form a circular cross-sectional configuration.
Abstract:
Apparatus and methods suitable for controlling and metering thermoplastic material or resin to multiple cavities in a multi-cavity injection molding tool are described, whereby the amount of resin injected into each cavity can be individually controlled. This system minimize overfilling or underfilling of individual article cavities in such a multiple cavity tool and, therefore, allows for the production of more uniform plastic articles from a multiple cavity mold or tool. In practice, a spindle, which is designed to rotate in a reproducible manner as resin flows past it, is inserted into the resin stream feeding each cavity. The amount of resin fed to a particular cavity is determined by measuring the rotation of the spindle. When the amount of resin fed to a particular cavity is equal to the amount appropriate for that cavity (the target amount), the shut-off valve associated with that cavity is activated, thereby terminating the resin flow to that cavity without affecting resin flow to the other cavities. Resin flow is continued until all cavities are filled with their respective target amounts of resin. The apparatus and methods of this invention are especially adapted for use in gas-assisted injection molding using multi-cavity equipment.
Abstract:
A closure including a container having a side wall with an attached closed end and an open end and a closure for closing the open end. The side wall of the container includes an inner wall and an outer wall at the open end and the closure includes a depending skirt which extends into the area between the inner wall and the outer wall. Three static seals are provided with a first radially extending seal defined by an end of the inner wall and an inner surface of the closure. A second static seal is defined by abutting surfaces of a pair of ridges, an outwardly extending annular ridge formed on the inner wall and an inwardly extending annular ridge formed on an inner surface of the skirt. A third static seal is formed by an inwardly facing annular surface formed on the outer wall and an outwardly facing annular surface formed on an outer surface of the skirt. A dynamic seal is provided as additional protection against pressure changes which could tend to break the first static seal. The dynamic seal is formed by an outwardly facing annular sealing surface on the inner wall and an inwardly and downwardly extending annular lip formed on an inner surface of the closure.
Abstract:
A shelf system utilizes a hingedly mounted shelf, and an assembly including a brace piece having a back portion contoured to provide elements disposed progressively inwardly with respect to a vertical axis. Securing the brace piece at any of several transverse positions on the shelf, relative to the vertical reference, will vary the angular attitude of the shelf; normally, the vertical reference will be the wall to which the shelf is attached and against which the contacting element of the brace piece will rest for supporting the shelf.
