Definitions

  • the invention relates to a cartridge for packaging poly­urethane sealing materials.
  • Sealing materials are usually packaged into cartridges resembling to a syringe body, with their cylindrical tubular body being similarly closed by a piston at the rear end thereof.
  • the seal­ing material contained in the cartridge will be ejected from the delivery end of the cartridge, through a suitable spigot-like member, once the thin diaphragm provided at the inner fore end side thereof, has been broken open by the said piston.
  • the spigot-like member is provided with an ex­ternal thread, such that an additional, internally threaded spout may be screwed thereon.
  • Both the piston and the cyl­indrical tubular body of the said cartridges are usually made of plastics material.
  • plastics material cartridges cannot be used for the packaging of polyurethane sealing materials, since the polyurethane sealing materials would leak out through the plastics material from which the body of the cartridges is usually made, and would undergo a gradual polymerization.
  • the manufacturers of cartridges for packaging sealing materials, polyurethane sealing materials included may manufacture only one type of cartridges of a non-metallic material, and may condition the said one type of cartridges, so as to make the same suitable for packaging polyurethane sealing materials.
  • the cylin­drical tubular body of said cartridges is provided with a lining for preventing polyuretane sealing materials from leaking out through the cartridge body, and from undergoing a gradual polymerization.
  • the lining consists of a metallic film, preferably a tube of polythene-covered aluminum, which is closed at its fore end, and which by a welding operation or by using any other suitable means, such as glues or adhe­sives, is bonded at least to the inner sidewall of the cyl­indrical tubular body of a cartridge, so as to be caused to sufficiently stick thereon.
  • the cartridge for containing polyurethane sealing mate­rials is closed at its rear end by a piston of plastics material, which is covered with an aluminum film.
  • a cartridge 1 for packaging sealing materials there is shown a cartridge 1 for packaging sealing materials.
  • the cylindrical tubular body 11 of cartridge 1 which is made of plastics material, has a round cross-section, is open at its rear end side 2, and is closed at its opposite fore end side by a cover 101 formed of one piece with the cartridge body 11, and being central­ly provided with a protruding spigot-like member 201, which is co-axial to the cartridge body 11, and is provided with an external thread, such that an internally threaded spout, not shown, may be screwed thereon.
  • This spout may be useful for an easier dispensing of the sealing material packaged into the cartridge 1.
  • the features of the cartridge as dis­closed above, and the method of making same are known to those skilled in the art.
  • Numeral 3 denotes the piston of plastics material which is suitably associated with the cylindrical tubular body 11 of cartridge 1, in a tightly sealing relation with the side­wall of the said cartridge body 11.
  • the said piston 3 is adapted for closing the rear end side 2 of the cartridge body 11 and for causing any sealing material, containted in cartridge 1, to be ejected from the fore end thereof, once the protective thin diaphragm 301 has been broken open
  • this cartridge When polyurethane sealing materials are to be packaged into the above disclosed cartridge, this cartridge must be made capable of holding a polyurethane sealing material, so as to prevent the same from leaking out through the cartrid­ge body, and from undergoing a gradual polymerization.
  • the invention attains this object by providing a lining to be laid on the inner fore end side and the inner sidewall of the cylindrical tubular body 11 of cartridge 1, which is thus made suitable for the packaging of polyurethane sealing materials.
  • the cylindrical tubular body 11 of the plastics material cartridge 1 for packaging poly­ urethane sealing materials is provided at its inner fore end side with a discoid lining 4 having an upstanding peri­pheral border 104 which contacts the lower end portion of the inner sidewall of the cartridge body 11.
  • the said dis­coid lining 4 is laid on the inner face of cover 101 closing the fore end side of the cartridge body 11.
  • the lining 4 is made from a punched sheet of a known material, comprising at least one layer of aluminum having one or both of its sides covered with a layer of polythene or any like suitable mate­rial.
  • FIG. 6 This material is shown in Figures 6 and 7, wherein A denotes the aluminum layer, and B denotes the polythene lay­er or layers.
  • the inner sidewall of the cylindrical tubular body 11 of cartridge 1 is provided with a tubular lining 5 made from the same material as the lining 4, and which is co-axially inserted into the cylindrical tubular body 11 of cartridge 1.
  • the tubular lining 5 is of such a size that it can be caused to intimately adhere to the whole suface of the inner sidewall of the cylindrical tubular body 11 of cartridge 1, and one end thereof is fitted into the upstand­ing peripheral border 104 of the discoid lining 4.
  • the discoid lining 4 and the tubular lining 5 are in­serted and positioned into the cylindrical tubular body 11 of cartridge 1 with the aid of one or more suitable man­drels, which may be used also for bonding the linings 4 and 5, respectively to the inner face of the cartridge cover 101 and to the inner sidewall of the cylindrical tubular body 11 of cartridge 1, for example, by the known methods of heat welding, ultrasonic welding, or high frequency welding, or by means of suitable adhesives or glues.
  • the said linings 4 and 5 may be separately applied to the inner fore end side and to the inner sidewall of the cylindrical tubular body 11 of cartridge 1, or they may be simultaneously applied to the cartridge body 11 with only one operation, by previously fitting them onto a single mandrel.
  • a known expansible man­drel is used for inserting and positioning the tubular lining 5 into the cylindrical tubu­lar body 11 of cartridge 1.
  • the discoid lin­ing 4 on the inner face of cover 101 of cartridge 1 has its border 104 surrounded by the fore end portion of the tubular lining 5 for the sidewall of the cylindrical tubular body 11 of cartridge 1
  • FIGs 3 and 4 there are shown two alternative ways of closing at is fore end the lining for the inner sidewalls and the inner fore end side of the tubular body 11 of car­tridge 1.
  • the lining 4 is bonded to the tubular lining 5 for the sidewall of the cylindrical tubular body 11 of cartridge 1, before the said linings 4 and 5 being in­serted into the cartridge body 11, and the upstanding border 104 of this lining 4 may be internally or externally fitted, into or on the side end section of the tubular lining 5.
  • the assembled linings 4, 5 are then inserted into the cylindric­al tubular body 11 of cartridge 1, and the tubular lining 5 may even be the only lining which is bonded to the inner sidewall of the cartridge body 11.
  • the same methods as dis­closed above in relation to Figures 1 and 2, also apply here for bonding together the linings 4, 5, and for bonding these linings to the cylindrical tubular body 11 of cartridge 1.
  • FIG. 5 there is shown still a different way of closing at its fore end the lining for the inner sidewalls and the inner fore end side of the tubular body 11 of car­tridge 1.
  • the said lining consists of a tubular lining 5 which is closed at its fore end by a transversal welding 105, the inserted lining 4 being here omitted.
  • the closed fore end of lining 5 is then bent down, to facilitate the insertion of this lining 5 into the cylindrical tubular body 11 of cartridge 1, and to allow the said closed fore end of lining 5 to be easily perforated, as the thin diaphragm 301 is being perforated.
  • the tubular lining 5 may consist of a one-piece tube of the material as per Figures 6 and 7, or the said lining 5 may be formed from a suitably rolled up and longitudinally welded sheet of the said material.
  • the piston 3 is provided with a covering formed by a film of polythene-covered aluminum.
  • the said covering also guarantees a metallic seal between the piston 3 and the rear end section of the cylindrical tubular body 11 of cartridge 1.
  • the cartrid­ge 1 consists of a cylindrical tubular body 11 of cardboard, such as, for example, a cylindrical tubular body 11 formed from a strip of cardboard being helically wound round itself.
  • the tubular cardboard body 11 of cartridge 1 has its fore end side clos­ed by a separate aluminum cover 101, which by means of a folded seam 12 is fastened to the said tubular body 11.
  • the rest of the cartridge body 11 is made as disclosed by referring to Figure 1, so that it is provided with a cen­trally located, threaded spigot-like member 201 which is initially closed by a thin diaphragm 301, to be perforated in known manner, whereby the sealing material contained in cartridge 1 can be dispensed therefrom.
  • the tubular cardboard body 11 of cartridge 1 may be lin­ed with an aluminum lining 5, and a disc 4 is formed inte­grally with the said aluminum lining 5, or it is in form of an insert, and/or it is made according to any one of the em­bodiments as disclosed by referring to Figures 1 to 5.
  • cover 101 closing the cylindrical cardboard body 11 of cartridge 1, according to the embodi­ment shown in Figure 8, is just made of aluminum, the disc 4 for lining the inner face of said cover 101, may not be pro­vided, and the lining 5 may line only the inner cylindrical sidewall of the said cardboard body 11.
