Patent number: 6355161Abstract: A set of bottles for containing dialysate chemical formulations, chemical cleaning agents or the like is described. The chemical formulation bottles come in two varieties, sodium bicarbonate and liquid acid formulations, each bottle having a slightly different shape. The different shapes cooperate with a bottle mounting structure in the dialysis machine to insure that bottles are correctly installed on their respective bottle opening mechanism.

Patent number: 5989661Abstract: 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.Type: GrantFiled: November 27, 1996Date of Patent: November 23, 1999Assignee: Continental PET Technologies, Inc.Inventors: Suppayan M.

Patent number: 5988417Abstract: 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.Type: GrantFiled: November 12, 1997Date of Patent: November 23, 1999Assignee: Crown Cork & Seal Technologies CorporationInventors: Jizu J.

Patent number: 5979696Abstract: A packing container for liquid products comprises a closure which opens and closes automatically when the pressure in the container varies, such that the container is easy to handle irrespective of its filling level and can be reliably secured to a wall or the like. The container also includes at least one flat side wall for securing it to a flat surface, and at least one concave or convex actuation surface in the region of opposing side walls such that the user can apply manual pressure.Type: GrantFiled: March 19, 1998Date of Patent: November 9, 1999Assignee: Henkel-Ecolab GmbH & Co.

Patent number: 5979326Abstract: 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.Type: GrantFiled: September 8, 1997Date of Patent: November 9, 1999Assignee: Riso Kagaku CorporationInventor: Yoshiharu Ohinata

Patent number: 5971184Abstract: A hot-fillable plastic container having a panel section of a size suitable for gripping the container in one hand. The panel section includes two opposing vertically-elongated and radially-indented vacuum panels, and two opposing horizontally-disposed and radially-indented finger grips. Each vacuum panel preferably has an invertible central wall portion movable from a convex first position prior to hot-filling of the container, to a concave second position under vacuum pressure following hot-filling and sealing of the container.Type: GrantFiled: October 28, 1997Date of Patent: October 26, 1999Assignee: Continental PET Technologies, Inc.Inventors: Suppayan M.

Patent number: 5960975Abstract: 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.Type: GrantFiled: March 19, 1997Date of Patent: October 5, 1999Assignee: Tetra Laval Holdings & Finance S.A.Inventor: Mattias Lennartsson

Patent number: 5954224Abstract: 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.Type: GrantFiled: November 1, 1996Date of Patent: September 21, 1999Assignee: Colgate-Palmolive CompanyInventors: Kenneth R. Berger, Patrick A. Connan, Robert L. Readdy

Patent number: RE36377Abstract: A collapsible container is disclosed having a top portion and a base portion joined by a generally cylindrical side wall structure, the generally cylindrical side wall structure has a central axis and a collapsible helical portion and the collapsible helical portion has a generally uniform radius and a generally flat side cross sectional shape with respect to the central axis. A cup section is also disclosed which can cause deformation of the collapsible container's side wall. The container is particularly suitable to store carbonated beverages and other consumer products.Type: GrantFiled: November 20, 1996Date of Patent: November 9, 1999Inventor: Neil Y. Gilbert
