Definitions

  • the invention relates to a liner for a container which can be closed with a lid and consists of thin-walled, flexible plastic, the upper edge of the liner being provided with an outwardly extending retaining collar.
  • Such linings of containers are known as flexible inner casings with cover films.
  • So-called round-bottom bags with lid foils are used for cylindrical bodies, so-called shape inliners, which also enclose the edge of the vessel (vessel border), have proven effective for bulbous vessels.
  • a deep-drawn film is usually used, which is adapted to the inner shape of the lid and encloses the border.
  • a major disadvantage of the separate assignment of inliners and cover foils is that the container edge (Bordur) is enclosed twice with foil. As a result, the necessary sealing effect is not infrequently impaired because the seal running around in the sealing groove of a container lid does not adequately compensate for the double foil overlay on the barrel edge.
  • Another lack of sealing in film systems is the high surface sliding effect of flexible films made of high-pressure polyethylene (LDPE), which are mainly used because of their otherwise generally good properties.
  • LDPE high-pressure polyethylene
  • the object on which the present invention is based is to find a lining of wide-neck lid containers which avoids the disadvantages described above in terms of assignment and sealing, without neglecting their advantages.
  • This object is achieved in that an inwardly projecting, circumferential support edge is provided below the retaining collar, on which a cover rests.
  • This new type of holding collar serves either as a level for thermoplastic connection with a cover film of any type or as a support for a loosely assigned film cut. It is crucial that the molded-on indentation is located immediately below the inner groove edge of a lid in order not to impair the fill level.
  • the particularly advantageous embodiment of the invention also creates an often desired membrane effect for pressure equalization in the lid cavity.
  • a seam connection between the inliner and the cover film can take place inside or outside a molding tool, as can the assignment of the required filling and emptying openings.
  • a container of this type achieves other advantages, however, if the filling and emptying openings in the area of the cover film are shaped as a slip cup. If closures are inserted in this way, they cannot hinder the lid closure flush with the inside of the lid, they can survive transport better and they can be emptied more easily. The same functions can later be performed via a container replacement lid with corresponding openings and holding devices as with a bunghole lid barrel.
  • the complete emptying is also possible because clean disposal by removing the light, thin-walled and flexible inliner, which can be folded to a minimum volume after the remaining content has been pressed out via the closure opening and can then be closed drip-free with the closure cap.
  • the closure function is to be assessed differently via a loose cover film overlay.
  • a self-locking film disc can be placed on the neck of a container. If the exact dimensions are specified, the inner edge of the cover sealing groove presses onto the attached cover plate in the area of the inner circumferential plane of the retaining collar (Level of evasion). In many cases, this seal is sufficient to prevent fill materials from escaping into the upper deck area. It is also advantageous, however, to have a molded-on film disc with edges that are angled upward and then protrude into the groove. Finally, a foil cover disk can have a seal for the retaining collar or can be located thereon.
  • cover film for locking purposes is conceivable if the holding collar itself serves as a locking element. Then the outer edge of the cover sheet must be formed with a uniform slight counter-evasion in order to snap under the retraction edge of the retaining collar when pressed on. As a result, the middle surface of the cover film lies slightly below the level of the holding collar.
  • the retaining collar itself can be designed in multiple forms.
  • the upper level is usually flat / straight for the purpose of a thermoplastic connection, while the lower return can be guided in the same way or, due to the better removal from the mold, is returned to the inliner wall at an oblique angle or in an arc.
  • FIGS. 1 to 11 A section through the upper edge of a container with a lid is shown in FIGS. 1 to 11.
  • the container can have, for example, the shape shown in DE-OS 1813687 and a cylindrical shape.
  • Figure 1 shows a cylindrical container 1, in which the border of the container edge 12 is approximately circular in cross section.
  • a lid 2 is placed on this container 1, which has a groove 11 corresponding to the border 12.
  • the lining 4 which consists of thin-walled, flexible and thermoplastically deformable plastic, primarily of LDPE, HDPE, PP or coextrusions in the end wall thicknesses, preferably less than 250 ⁇ - depending on the lining volume.
  • this lining 4 has an inwardly projecting, peripheral support edge 5.
  • a holding collar 18 is formed on the lining 4, which is placed on the border 12 of the container 1 and which is held elastically by a seal 3 inserted into the space between the border 12 and the groove 11.
  • the seal 3 can be firmly connected to the groove 11 of the cover 2.
  • the cover 6, which preferably also consists of the same types of plastic, is placed on the support edge 5 and is held in this position by the cover 2.
  • the lining 4 with its peripheral support edge 5 is located in a bulbous container 1, preferably made of plastic, which ends in a border 12.
  • the cover 2 is also made of plastic and has a molded-in border urinal groove 11.
  • the cover 6 is connected to the support edge 5 by an endless weld 8.
  • a projection 20 extends downward on the inside of the cover 2. It can be in length be designed so that it presses against the cover film 6 in the closed state of the container.
  • FIG. 3 shows an embodiment in which the support edge 5 of the container lining 4 is formed by a flange-like, internal connecting seam 8 between the holding collar 18 and the lining 4.
  • Figure 4 corresponds essentially to the embodiment shown in Figure 2. However, it additionally shows a fill and drainage bung 9 welded into the cover 6 with a closure cap attached.
  • Figure 5 shows a container 1, as shown in Figures 2 and 4.
  • the peripheral support edge 5 according to the invention is provided with a peripheral recess 13 into which the cover 6 can be inserted with a corresponding groove and can be pressed in by the projection 20 provided on the cover 2.
  • FIG. 6 is an embodiment corresponding to FIG. 5, in which the support edge is provided with an essentially wedge-shaped groove 13 into which the cover 6 engages and on the inclined edge of which this cover 6 can be pressed by the projection 20 of the cover 2.
  • FIG. 7 shows an embodiment in which the support edge 5 has a circumferential recess 13 into which a seal 14 is inserted, against which the edge of the cover 6 can be pressed in a sealing manner with the projection 20 of the cover 2. This can be supported by inserting a dimensionally stable support ring 21 with a horizontal surface into the circumferential evasion.
  • FIG. 8 shows an embodiment corresponding to FIG. 7, in which a groove-shaped recess 13 is formed in the support edge 5, into which the correspondingly formed one groove-shaped edge 15 of the cover 6 can be used.
  • a seal 14 is provided in the recess 13.
  • the support edge 5 is formed by an endless weld 8 corresponding to that shown in FIG.
  • the cover 6 is held on this by means of a peripheral projection 19 which projects downward at the edge.
  • FIG. 10 shows an embodiment corresponding to FIG. 2, in which the cover 6 has a bulge 16 with which this cover can be inserted and removed particularly easily.
  • FIG. 11 shows an embodiment corresponding to the figure, in which the bulge 16 of the cover 6 protrudes downwards.
