  • the top edge of the container may be deformed, a part of the this top edge including the circumferential trough portion 47 and the respective sealing surfaces 15 and 39 in the vicinity of the circumferential point of impact 73 being bend out of the general plane of the top 11 of the container.
  • the upwards force F l on the inner side of the lid 5 may dome the central portion 27 of the lid upwards, whereby the inner trough wall 49 will be pulled towards the centre of the container, especially at a bending point of the top edge, consequently pulling the trough bottom 51 and the lower part of the outer lid wall portion 29 towards the centre of the container.
  • the upper flange portion will per se provide a cushioning effect that enhances the height from which the container may be dropped without leaking as a result of the impact.
  • the securing ring 55 should have a sufficient strength and rigidity to provide the effects and function described above.
  • a suitable material for the securing ring 55 is polypropylene, but other materials providing a suitable rigidity and strength may be used.
  • an acute angle ⁇ of approximately 45° is used in the embodiment shown different acute angles may be used e.g. up to 80° or 70° from the vertical. Normally the acute angle will be in the range of 35° to 55° from the vertical.
  • the geometry of the profile of the securing ring 55, including the acute angle ⁇ should be designed for the upper flange portion 59 to withstand collapsing when the container is dropped from a given maximum height of expected "survival" i.e. a maximum height from which the container is expected to be able to drop without leaking. Withstanding collapse the securing ring 55 will protect an upper rim part of the container body most effectively from direct impact. However even a smaller benefit of the invention may be obtained even in case of the upper flange portion collapsing since the upper flange portion still will absorb part of the energy of the impact.
  • Fig. 4 shows the profile of the securing ring 55 of the present example of an embodiment.
  • the profile comprises a major annular recess 75, which provides for stacking filled containers as such containers would be stacked without the securing ring 55.
  • the annular recess 75 provides space for accommodating a circumferential joint at the bottom of a container stacked on top of the container shown.
  • the part of the lower portion 57 below the annular recess 75 has a substantial thickness compared to the parts above of the securing ring 55.
  • the securing ring 55 may be recessed e.g. as indicated in Figs. 4 and 6 by providing bores 77 in the part of the lower portion 57 below the annular recess 75 thus reducing the local wall thickness in said part.
  • the bores 77 may as indicated in Fig. 4 be provided as through holes, as blind holes, or as a mixture thereof.
  • Fig. 6 shows a small sector 79 provided with bores 77 but it should be understood that preferably such bores 77 are distributed evenly along the entire circumference of the securing ring 55.
  • the outer portion 63 is void of recesses to provide for the second bead 65 to extend continuously circumferentially along the inner surface 41 of the outer lid wall portion 29.
  • the upper flange portion 57 extends at an acute angle ⁇ above the annular ledge 33 it is possible, even without removing the securing ring 55, to open the container 1 in the usual manner by inserting a screw driver-like tool 81 below the rim portion 33 of the lid 5 as indicated in Fig. 4 and lift the lid 5 from the container body 3 using the screw driver-like tool 81 as a lever.
  • the insertion of a screw driver-like tool 81 may however be facilitated by recessing the upper flange portion, which thus may be interrupted in sectors of e.g. 2 cm along the periphery of the securing ring 55.
  • Fig. 7 shows an embodiment in which, compared to the embodiment shown in Fig. 4 , the second bead 65 of a securing ring 55a is omitted.
  • Fig. 7 generally shows the same container as the preceding figures, but with a different variant of the securing ring. Accordingly similar features of the variants have been given similar reference numerals.
  • recesses 85 in the supporting portion 57 are elongated in the circumferential direction and are open downwards.
  • excess adhesive 64' may penetrate into the recesses 85 when the securing ring 55a is inserted into the circumferential trough portion 47 during manufacture or in case of an impact.
  • the securing ring 55a comprises an inner raised annular portion 87 provided for supporting similar containers stacked on top of the container shown.
  • the bottom of a container stacked on top is supported by a raised lid portion 89 adjacent the circumferential trough portion 47 a circumferential joint at the bottom of the container stacked on top being accommodated in the circumferential trough portion 47.
  • the circumferential joint at the bottom of the container stacked on top will be accommodated in an annular recess 75a.
  • the securing ring 55a In order to provide a firm support for containers stacked on top the securing ring 55a this is at its bottom provided with circumferentially spaced knobs or protrusions 91 that penetrate the adhesive to make firm contact with the trough bottom 51.
  • securing rings 55 and 55a described so far may be manufactured by injection molding to be subsequently inserted in the circumferential trough portion
  • Fig. 8 shows yet a different embodiment.
  • a securing ring 55b has been provided by initially inserting a first string of hot-melt adhesive 64a that remains tacky when set and subsequently inserting a second string of hot-melt providing the securing ring 55b proper.
  • the second string of hot-melt is e.g. EVA that sets to a firm non-tacky condition.
  • the securing ring 55b lacks an upper flange portion and accordingly this embodiment lacks the cushioning effect of such flange portion.
  • this embodiment still provides for the effect of distributing a horizontal component F h of the force of an impact against the joint 21 or rim portion 31 of the container, only in this case the force is distributed from the material of the container, eventually the outer lid wall portion 29 to the securing ring 55b.
