Definitions

  • PATENTEDMAY 9 I972 SHEET 3 OF 3 APPARATUS FOR SEALING UPPER CLOSURE COVERS OF CONTAINERS The present invention relates to a process of and apparatus for sealing upper closure covers of containers for food products.
  • hermetically sealed plastic containers for containing food products of various types, including vegetable products, such as olives and the like. It is essential in the processing of these products to obtain a hermetic closure of the container after it has been filled with the food product in order to avoid the harmful effect of the ambient air. For this purpose various closure methods have been used in order to attempt in all cases a perfect isolation from the surrounding air.
  • the covers are customarily of a different material than that of the container, covers made from a thin aluminum sheet being frequently employed.
  • It is yet still another object of the present invention to provide an apparatus for sealing containers comprising a hollow, cylindrical body having electric heating resistors therein and having a loweredge, the surface of which coincides with that of an annular rim to be sealed.
  • An inner core is mounted within the hollow cylindrical body having a lower surface substantially flush with the lower edge of the cylindrical body and having as an essential feature an internal cooling means which may comprise especially a means for the forced circulation of water.
  • the arched parts when so positioned together cooperate'with a sealing device.
  • the advance and withdrawal of the arched parts can easily be mechanized, thereby generally mechanizing the operation of the apparatus of the present invention.
  • FIG. 1 is an axial cross-sectional view of the arrangement of means for effecting the sealing of the mouth of a container
  • FIG. 2 is a plan view of the structure of FIG. 1;
  • FIG. 3 isa section along the lines 4--4 of FIG. 4, partially broken away;
  • FIG. 4 is a top plan view of the closed container, partially broken away;
  • FIG. 5 is a section along the lines 5-4 of FIG. 6;
  • FIG. 6 is a plan view of another embodiment of the present invention illustrating a sealing unit with circumferential heating resistors.
  • FIGS. 1 4 it is essential in the present invention to effect the sealing of an essentially metal cover I, of reduced thickness onto an upper flange 2 having the shape of an outwardly directed annular shoulder which forms part of a container 3 made preferably of synthetic material, and particularly thermoplastic material, or the like, intended to contain food products therewithin.
  • a hollow cylindrical member 4 of annular cross-section is provided which has a flat annular bottom surface 40 of a width desired for the sealing of the cover 1 and the shoulder of the flange 2, and substantially of the same shape and size as that of the annular flange 2, the annular member 4 having a vertical projection corresponding to a circular rim.
  • the member 4 has on its inside, in its cylindrical walls, independent heating elements, such as resistors, housed in cavities 5, the latter having a shape complementary to the shape of the resistors.
  • a cooling device is provided, essential to the present invention, which can substantially maintain the thermal equilibrium of a portion of the cover 1, which portion is limited or bounded at its outermost periphery by the annular sealing zone, for which purpose, in accordance with the present invention, there can be provided a cylindrical core or cooling member 6 housed within the hollow member 4 and having a flat lower closed circular surface 7 substantially abuttingly flush with and in the same plane as the annular bottom surface 4a of the member 4, whereby, by direct contact, the refrigeration or cooling of the cover 1 is facilitated.
  • the cooling member 6 includes refrigeration or cooling means which are represented, although not limited thereto, by two tubes 8 and 9 for the entrance and discharge of cooling water, respectively, and an intermediate partition 10 defining a lower refrigerant chamber 11 adjacent the closed circular surface 7.
  • two complementary clamping and supporting parts 12 and 13 (FIGS. 1 and 2), which are formed with semicircular arcuate recesses 14 and 15 such that when they are moved so that they abut each other, they form a circular central opening complementary to and surounding the zone of the neck of the container 3 adjacent and below the flange 2 on which the cover of the con tainer is sealed.
  • a longitudinal guiding of the parts 12 and 13 may be provided, the actuation thereof efi'ected by means of individual rollers 16 and 17, whereby, by the cooperation of the parts with suitable outer guides 12a and 13a, preferably of a machine, the desired displacement of the parts can be effected.
  • suitable outer guides 12a and 13a preferably of a machine
  • the desired displacement of the parts can be effected.
  • a sealing member 18 effects the sealing and has the shape of a hollow cylindrical element.
  • member 18 has a group of inner resistors 19 which are disposed traversely or circumferentially and contain a cooling element 20 which has internal passageways 21 and 22 for the passage of a refrigerant fluid, which may be water, or any other coolant. Furthermore, two parts of half-moon 23 and 24 assure the sealing operation upon a displacement toward each other by means of guide members 23a and 24a of the machine, via rollers 25 and 26.
  • An apparatus for sealing a circular closure cover onto a container having a flat annular flange, defining an open end of the container comprising means for sealing a peripheral annular zone of a circular metallic closure cover onto an annular thermo-plastic flange of said container,
  • said sealing means comprises a hollow cylindrical sealing member including cylindrical walls having a flat annular bottom surface substantially of the same size as that of said annular flange of said container, and said hollow cylindrical sealing member adapted to be positioned with said bottom surface on said closure cover substantially directly above said annular flange of said container,
  • heating means disposed in said cylindrical walls of said hollow cylindrical sealing member and extending to adjacent said bottom surface
  • cooling means in said cooling member for cooling said lower closed circular surface.
  • An apparatus for sealing a circular closure onto a container having a flat annular flange, defining an open end of the container comprising means for sealing a peripheral annular zone of said circular closure cover onto said annular flange of said container,
  • said sealing means comprises a hollow cylindrical sealing member including cylindrical walls having a flat annular bottom surface substantially of the same size as that of said annular flange of said container, and said hollow cylindrical sealing member adapted to be positioned with said bottom surface on said closure cover substantially directly above said annular flange of said container,
  • heating means disposed in said cylindrical walls of said hollow cylindrical sealing member and extending to adjacent said bottom surface
  • cooling means in said cooling member for cooling said lower closed circular surface
  • said parts including upper surfaces upon which said flange is supported in said clamping position.
  • cooling member includes a lower refrigerant chamber adjacent said lower closed circular surface, and entrance and exit conduits for passing a liquid coolant into and out of said refrigerant chamber, said refrigerant chamber and said conduits constituting said cooling means.
  • heating means comprises resistor elements.
  • resistor elements are circumferencially disposed in said cylindrical walls of said sealing member.
