Patent number: 5791519Abstract: A source of liquid soap for washbasins and the like is provided by a flexible, collapsible bag filled with liquid soap. A hollow needle is penetrably inserted through the material of the bag, which penetration develops a seal about the needle. The needle is connected through a conduit to a dispenser for the soap. A source of vacuum in communication with the conduit, the force of gravity or a force externally imposed upon the bag to compress it, actuates a flow of soap from the bag through the needle for discharge from the dispenser. As liquid soap is evacuated from the bag, the bag collapses. Upon depletion of the soap, the needle is withdrawn and inserted into a replacement bag of soap.Type: GrantFiled: December 27, 1995Date of Patent: August 11, 1998Assignee: International Sanitary Ware Manufacturing CY, S.A.Inventor: Karel Carl Van Marcke

Patent number: 5775386Abstract: An apparatus and a process for filling a plural chamber container, such as a container, with plural flowable materials. The container might be a two-compartment dentifrice container or a two-compartment adhesive container, for example. The container has internal partitioning dividing it into plural chambers, and the partitioning must be properly positioned to permit supply nozzles to enter the respective chambers. In one embodiment, the partitioning is positioned by probes which are inserted into the chamber, following which relative rotation between the container and the probes causes the probes to position the partitioning. In a second embodiment, air nozzles emit air jets to position the partition. In another embodiment, an electrostatic charge is induced on the container sidewall and on the partition, and the like charges cause the sidewall and the partition to repel each other, positioning the partition.Type: GrantFiled: June 13, 1996Date of Patent: July 7, 1998Assignee: Colgate-Palmolive CompanyInventor: Patrick Andre Connan

Patent number: 5759501Abstract: A container for institutional detergents, preferably tablets, includes a rigid large screened base and a flexible plastic film sidewall heat bonded to the peripheral surface of the base. The container is filled, preferably from its top portion, with tableted detergent and closed with a single heat seal along the top surface of the wall of the container. The screen surface is then closed with a removable, peel-off seal or removable cap. The upper portion of the container will include a handle which makes it easy to transport the container and place it into a dispenser for use. In use, a water nozzle will spray upwards onto the surface of the screen base through the holes in the screen, dissolving detergent and allowing the solution to pass downwardly to a drain, which directs it to a ware washing apparatus.Type: GrantFiled: November 15, 1996Date of Patent: June 2, 1998Assignee: Diversey Lever, Inc.Inventors: James Livingston, Donald Wright, Tiziano J. Bellon, Kenneth James Roach

Patent number: 5746352Abstract: A first embodiment of a package including superimposed flexible opaque and transparent sides and a circumferential peripheral seal determining an interior sealed enclosure for storing a liquid material includes two contiguous depending seals separated by a preformed slot dividing the enclosure bilaterally into a storage reservoir and a dispensing channel in fluid communication. The dispensing channel includes a closed lower end contiguous to a notch in the peripheral seal. Tearing the package at the notch results in collaterally tearing open the channel lower end and a contiguous portion of the peripheral seal, thereby enabling removal of package contents. Use of a ruled scale imprinted on the opaque side proximate to the dispensing channel and viewing through the transparent side the disposition of material in the channel enable the selection of a measured quantity of material to be expelled from the channel.Type: GrantFiled: May 21, 1996Date of Patent: May 5, 1998Inventor: Arthur P. Corella

Patent number: 5743435Abstract: A collapsible bag for use in containing and dispensing a liquid includes a bladder layer and an outer layer. The bladder layer includes a pair of inner opposed panel sections sealed together to provide an enclosed region. The inner panel sections have an inner surface facing the enclosed region and a plurality of ribs formed thereon, and one of the inner panel sections has a first product-dispensing hole therethrough. The outer layer includes a pair of outer opposed panel sections covering the bladder layer and one of the outer panel sections includes a second product-dispensing hole therethrough aligned with the first product-dispensing hole. A spout is attached to the outer layer and covers the first and second product-dispensing holes to provide access to the enclosed region. The bag may be used in a box to dispense liquids.Type: GrantFiled: June 13, 1997Date of Patent: April 28, 1998Assignee: Reynolds Consumer Products, Inc.Inventor: Mladomir Tomic

Patent number: 5731021Abstract: A collapsible canteen formed by a collapsible carton having nested therein a collapsible pouch whose open mouth is in alignment with a neck projecting from the carton. The collapsible canteen which has a charge of powder deposited in the pouch is adapted to produce, in situ, a beverage when a hot or cold liquid is poured through the neck of the canteen into the pouch to dissolve the powder the nature of which determines that of the beverage.Type: GrantFiled: April 10, 1996Date of Patent: March 24, 1998Inventor: Donald Spector

Patent number: 5699936Abstract: A liquid container/dispenser including a container body defining a flexible wall for storing a liquid and a tube member having a first end portion placed outside the container body and a second closed end portion placed inside the container body. The tube member has an opening device provided in the second closed end portion of the tube member inside the container body. The second closed end portion can be broken off from the rest of the tube member inside the container body by a force applied through the wall of the container body. The wall of the container body is preferably made from a flexible material so that the wall can be flexibly brought into contact with the tube member inside the container. The liquid container with the novel dispensing system assures the sealed storage of liquid in the container and yet facilitates clean, quick and safe dispensing of the liquid.Type: GrantFiled: September 8, 1995Date of Patent: December 23, 1997Assignee: Sercomp CorporationInventor: Masahiko Sakamoto

Patent number: 5690253Abstract: A flexible and collapsible bulk bag having an upright orientation in use with top and bottom end access openings to the exterior of the bag through which a flexible and collapsible liner is received in the bag, the liner also having top and bottom access openings through which the bulk contents are respectively entered and discharged. When the bag is expanded and filled it has a pair of spaced apart and generally conical ends formed by four triangular portions interconnected by four generally rectangular side walls, with the ends convergently tapering toward their associated access opening. The bag when empty can be collapsed into a compact, flat configuration having a pair of overlying front and rear panels with a pair of folded gusseted side panels received therebetween. Alternatively the liner has a rigid discharge outlet spout and a protective exterior flap spans beneath the spout outlet closure to serve as an openable, flexible protective barrier for the same.Type: GrantFiled: August 29, 1996Date of Patent: November 25, 1997Assignee: Custom Packaging Systems, Inc.Inventor: Lee LaFleur

Patent number: 5678732Abstract: A process for making a container of heat-sealable plasticized sheet material, provided with a pouring spout and formed of a pair of facing walls having two side edges connected to each other by side walls folded to create side bellows. The process comprises the steps of sealing the upper edges of the facing walls so as to define an opening, of providing a small tube of a rigid material fitted with a flange that extend wider than the opening and that defines the spout and a thin cane, of inserting the thin cane into the container through the opening till the flange meets the border of the upper sealed edges, of folding said flange on the outer faces of the facing walls to cover the edges, and of tight sealing the flange to the edges.Type: GrantFiled: September 29, 1995Date of Patent: October 21, 1997Inventor: Belloli Gianpaolo
