  • Patent number: 4799723
    Abstract: This relates to a carrier for cups or containers. The carrier is formed from a flat sheet of plastic material and has a pair of openings therein on opposite sides of a transverse bar for receiving upper intermediate portions of cups. Each of the openings is defined by a peripheral strap which will tightly engage an intermediate upper portion of a vertically tapered cup. Further, generally surrounding at least one of the openings is a carrying strap defined by a C-shaped cut which also defines the article engaging strap for that opening. In one form of carrier there are two carrying straps and in another form there is a single carrying strap.

  • Patent number: 4796766
    Abstract: This relates to blow molded containers, and particularly to the formation of blow molded containers formed of a plastic material which is subjectable to a high degree of biaxial orientation for maximum strength. Two containers are formed in each blow molding operation with each container having throughout the stress areas thereof a high degree of biaxial orientation. A container may be in the form of a bottle having an as formed open bottom which is closed by a metal end unit seamed in place. Other containers will have open mouths closed by conventional closures including metal end units which are seamed to the container body or by closure caps which may be releasably interlocked with the neck finish of the container in several known modes. In every instance the containers are formed with a minimum of scrap. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.

  • Patent number: 4786245
    Abstract: This relates to a blow molding machine of the type for blow molding large articles such as containers of the one gallon to five gallon size from a parison in the form of an extruded plastic material tube. The machine is of the rotary type and has a plurality of stations each carrying a mold unit of which one half is fixed and the other is mounted for radial movement between open and closed positions. The main shaft of the machine is of a large diameter and is tubular so that the necessary manifolding for gas and coolant supplies may be readily incorporated in the main shaft in an entirely different manner from that heretofore utilized. Also, among other features of the machine, is the provision of hollow spokes which serve not only to support outer mold halves for radial movement, but also serve as manifold accumulators for the necessary operating gases.

  • Patent number: 4786455
    Abstract: This relates to an apparatus for injection molding preforms for beverage bottles wherein a minimum cycle time is involved. Cores over which thermoplastic material is injection molded to form preforms for use in the blow molding of bottles are provided in sets and carried by a rotary turret so that as soon as the injection molded thermoplastic material has sufficiently set to permit its transfer with its associated core out of an injection mold cavity, the apparatus may be actuated to remove first injection molded preforms and thereafter immediately present a new set of cores to the injection mold cavities. This provides ample time for the cooling of the preforms so that when removed from the cores they will not be unduly deformed. In accordance with the feasible use of the apparatus, plural preforms, on the order of twenty-four and greater, may be formed with a cycle time on the order of 10-12 seconds.

  • Patent number: 4601869
    Abstract: A method for blow molding from preforms hollow articles, particularly beverage bottles, at a high production rate. The method incorporates a clamp assembly which receives therein carriers containing a number of preforms arranged in a line and wherein there are two mold units, one on each side of a central longitudinally elongated clamp member which is mounted for transverse reciprocatory movement. When the clamp member is positioned to close one mold unit, it operates to open the other mold unit so that while preforms in the closed mold unit are being blow molded, the other mold unit is open and may have the carrier supporting previously blow molded articles displaced therefrom and replaced by a carrier containing a new set of preforms whereby, when the blow molding operation of the one mold unit is completed, the other mold unit is ready for closing and a blow molding operation.

  • Patent number: 4601865
    Abstract: A blow molding operation wherein centering rods are associated with preforms at least during the initial portion of the blowing cycle wherein the preforms are primarily axially elongated and wherein the freely suspended lower end of each preform must be guided against radial movement. In order to assure that the associated preform centering rods will remain in centering position with respect to the preforms at all times and will not engage the preforms so as axially to stretch the preforms, a control is provided for coordinating the advance of the preform centering rods with the introduction of blowing gas into the preforms, and thus with the axial elongation of the preforms due to internal blowing pressure.

  • Patent number: 4560080
    Abstract: This relates to an end, preferably a bottom end, for a metal shipping container wherein the end panel is recessed so as to bear the weight of the product shipped within the container. The invention particularly relates to the reinforcing of the end panel by an annular rib formed in the radially outer part of the end panel near to but spaced from the seam which joins the end to a container body. The annular rib is concentric to the container and is axially downwardly offset so as to be axially upwardly opening. The reinforcing rib is of a preferred depth and width ratio with respect to one another and to the container diameter.

  • Patent number: 4531650
    Abstract: This disclosure relates to a closure formed of plastics material for use in conjunction with a container also formed of a plastics material. The closure is particularly adapted for use with containers in the form of bottles which are intended to have a product packaged therein under pressurized conditions. The closure cooperates with a lip of the bottle so as to radially inwardly deform the lip with the exterior surface of the lip forming a seal with the closure. The portion of the closure engaging the lip is drawn radially inwardly under pressure by the axial deformation of an end panel of the closure.

  • Patent number: 4525401
    Abstract: This disclosure relates to a plastic bottle having a bottom structure of the champagne bottle type. The bottom is reinforced by radiating ribs which are circumferentially spaced and the ribs, utilizing a minimum of material, stiffen the bottom so as to prevent the domed inner section of the bottom from reverting and also greatly resist creep of the bottom under the influence of time and internal pressure. The ribs may be only across the juncture section between inner and outer sections of the bottom, or may extend entirely from the outer section across the juncture section and substantially to the domed center of the domed section. The ribs may also be upstanding and serve to function as guides for a liquid product being placed into the bottle so as to reduce turbulences and aid in expediting the filling operation.

  • Patent number: 4522770
    Abstract: This relates to the removal of indentations in the sealing surfaces of plastic bottles, particularly blow molded bottles. The neck finish of each bottle, as it moves along a discharge conveyor from a blow molding machine, is heated to a temperature approaching the glass transition temperature of the plastic material, at which temperature the memory of the plastic material begins to induce slight flow and wherein the indentations are eliminated by the flow of the plastic material of the sealing surface.
