  • Patent number: 6044996
    Abstract: A hot fill container formed from a polymeric material is disclosed. The container comprises a base (4), a body (2), and a neck (1), wherein the body (2) comprises an odd number of spaced-apart panels (5) that are responsive to internal pressure changes in the container. Hot fill bottles of a given capacity having an uneven number of deformable panels, e.g., five of a given wall thickness, unexpectedly accommodate significantly higher volume reductions before collapsing and distorting in an uncontrolled manner than known hot fill bottles of the same capacity having an even number of panels, e.g., six of the same wall thickness.

  • Patent number: 5989661
    Abstract: A preform and container design for a pressurized refillable plastic container, such as a PET carbonated beverage container, having a base section with increased resistance to sprue cracking. Sprue cracking, which may be a problem in warmer climates, is believed to be caused in prior designs by an entrapment of material between the stretch rod tip and the blow mold base during blow molding of the container, which entrapment causes surface defects in the container adjacent the sprue. These surface defects expand during flexing of the container dome, caused by alternating cycles of thermal shrinkage and expansion during container cleaning and filling. Sprue cracking can be reduced by eliminating a depressed dish adjacent the sprue in prior known refillable containers, and may further be reduced by modifications to the preform and container wall thickness ratios and base clearance height.

  • Patent number: 5988417
    Abstract: A plastic container that is designed for optimal strength and lightweighting characteristics includes a finish portion, a bottom portion that has a plurality of support feet and a corresponding number of grooves defined between the support feet, and a main body portion. According to one feature of the container, the main body portion has at least one groove defined in its smooth label area that is oriented so as to have an axial component and so as to extend to near a bottom of the label portion for permitting condensate to drain from the label portion. This reduces the potential for condensation-induced label delamination. According to another feature of the container, the main body portion further has a tapered neck portion that has a plurality of undulating grooves defined therein to provide structural reinforcement. The main body of the container also has a lower end that is configured so as to have a number of generally axially extending channels that extend toward the bottom portion.

  • Patent number: 5979326
    Abstract: To remarkably decrease the amount of material for the manufacture of ink containers and the volume of the ink containers after use, so as to contribute to the economy of natural resource consumption and solving the problem of destruction of global environment by the waste of products, without sacrificing the easiness of handling of the ink containers for printers, the ink container for directly storing ink is principally constructed by a thin walled vessel contractible according to discharge of ink therefrom, with a nozzle being connected to an end portion of the vessel, with a disk handle being mounted to the nozzle, so that the disk handle can be grasped by five fingers of a hand for carrying the ink container by hand and for removing a cap therefrom. For the ink container being housed in a printer, the ink container is charged into a reinforcing case with the nozzle and the disk handle engaged with an end wall portion of the case, so that the ink container is handled like the case.

  • Patent number: 5960975
    Abstract: A packaging material web for a self-supporting packaging container wall which includes a number of continuous wall panels manufactured from flexible material layers which are interconnected with one another by means of a pattern of seals. Between the seals, there are formed cells which are inflatable with a view to imparting to the material the requisite rigidity. A packaging container manufactured from the packaging material comprises a number of wall panels provided with inflatable cells, the length of the wall panels on inflation of the cells being reduced so that the height of the packaging container shrinks. Along one of the vertical side edges of the packaging container, there is a sealing joint (10) which is less flexible and counteracts such shrinkage so that the packaging container tends to be warped. In order to counteract this, the seals defining the cells are given asymmetric form, with one narrow and one broad end.

  • Patent number: 5954224
    Abstract: Tubular containers can be produced by injection stretch blowmolding processes. Such processes comprise the biaxial stretching of the preform as the preform is being converted into the tubular container. The preform will be stretched longitudinally by means of a stretch rod and laterally by means of the pressure of the blowing gas. The tubular containers produced by these processes will have burst strengths three to five times that of other tubular containers and can be produced in a thin wall collapsible form. Further, the tubular containers can be single chamber containers or multi-chamber containers.
