  • Patent number: 4565304
    Abstract: A liquid-dosing apparatus has a lower tube centered on an axis and having a lower end provided with a nozzle, an upper tube telescoping coaxially with the lower tube and defining therewith an axial passage extending upward from the nozzle, A supply for feeding the liquid to the passage in the upper tube, and a drive that vertically reciprocates one of the tubes axially relative to the other. Respective upper and lower annular bladders in the tubes can be pressurized to block the passage in the respective tube therewith and depressurized to unblock the passage in the respective tube. A controller connected to the drive and pressurizing system alternately pressurizes and depressurizes the bladders synchronously with vertical reciprocation of the one tube. These bladders are annular, hollow, and have inner peripheries that lie flush in the passage when the bladders are depressurized. In addition to the nozzle, tubes, and bladders are all of the same flow section and shape, whereby the passage is axially uniform.

  • Patent number: 4470514
    Abstract: The invention relates to a container for food substances, in particular for small portions of a drinkable food substance. Such container has an upper outwardly radially extending edge portion on which a foil is sealingly affixed thereby sealing the food substance within the container. Moreover, the container has affixed thereto a banderole strip for providing a hygienic condition for a person consuming the food substance. The undersurface of the radially outwardly projecting edge portion of the container is provided with a structurally weakened zone, preferably in the form of an annular groove. By bending this outer edge portion upwardly it is sheared off the container in the structurally weakened zone and thereby presents a hygienically flaw-free drinking edge. Additionally, the outer peripheral surface of the container 10 can be exposed by severing a partial banderole strip from the banderole, which partial banderole strip is immediately adjacent to the radially outwardly extending edge portion.

  • Patent number: 4452580
    Abstract: Deep-drawing machine for manufacturing containers out of thermoplastic foil material having an arrangement for inserting into the hollow mold prior to the deep drawing step a banderole-shaped strip section. The machine includes support means for a roll of foil material, means for transporting the foil material, a heating arrangement as well as a forming arrangement and said forming arrangement consists of a stationary counter mold and the hollow mold movable perpendicular to the foil plane, which is pressed against a counter mold after the heating of the foil. After the container is formed by means of a pressure medium, the strip sections, which have been introduced into the hollow mold, are sealed onto the container. The arrangement for inserting the banderole-shaped strip sections into the hollow mold includes a winding mandrel which is stationary with respect to the axially movable hollow mold.

  • Patent number: 4394115
    Abstract: An improved heat-forming deep-drawing molding machine for producing receptacles with thermoplastic banderoles, which machine includes a mandrel which coacts with a mold or a forming chamber for forming a closed banderole coil or loop. The mandrel has substantially the shape of the mold cavity. The mandrel slidably reciprocates in the mold cavity relative to the mold or the forming chamber and has a fixed transverse section relative thereto. The mandrel is composed of stationary and rotatable parts relative to the forming chamber. The rotating parts coact with the curved or round parts of the forming chamber or mold cavity. The rotating parts include suction channels which bias the banderole thereagainst so as to effect an advancing movement of the banderole in the forming chamber. The suction channels are operatively connected to a vacuum source.

  • Patent number: 4217163
    Abstract: In a hot forming machine in which molding means deform a thermoplastic foil band and cutting and stamping means further process the deformed foil band. A photocell is adapted to scan marking indicia on the foil band and to adjust a lengthwise adjustable connecting member in accordance with such scanning. The connecting member forms part of an advancing arrangement for the transported foil band. This advancing arrangement includes a swing arm pivotally mounted in the machine; a first shaft mounted on the swing arm in proximity of the free end thereof; and an eccentric rigidly secured to the first shaft and pivotally connected to the connecting member which is also pivotally connected to the swing arm.

  • Patent number: 4018028
    Abstract: An arrangement is described for registering stretchable lids with mating product-filled troughs of a heat-sealed product container prior to the heat-sealing operation. The troughs are preformed at first intervals on a first strip, which is successively indexed through the first interval into the heat-sealing station. The lids are defined between regularly spaced detectable markings on a second strip, which is moved into the heat-sealing station simultaneously with the first strip. The markings on the second strip are normally spaced by a second interval slightly smaller than the first interval. At the end of each indexing movement, a marking on the second strip comes into alignment with a photocell to generate a signal.
