Definitions

  • This invention relates to a container closure for an open-ended container comprising an outer wall, an inner wall and a side wall, said walls together forming an air space and wherein the exterior side of the side wall is sealingly engageable with the inside of the walls of the open-ended container.
  • closures of these known containers comprise means for causing the inner wall of the closure to distend thereby drawing the side wall inwardly during opening and closure of the container and out of sealing contact with the inside of the walls of the container.
  • British patent specification No. 2 058 026 discloses a similar container closure as well as a closure comprising means for distending the outer wall of the closure during opening and closure of the container.
  • the object of the invention is to provide a container closure of the above-mentioned type which prevents leakage and which is not disengaged from an open-ended container if the container with contents is subject to strong mechanical forces, such as impacts, e.g. in connection with the dropping of the container on the floor.
  • closure of the invention which closure comprises a side wall which is more easily deformable than the outer wall and which comprises an essentially airtight air space.
  • the side wall of the closure forms an integral part of the outer wall and the inner wall comprises a peripheral annular flange in sealing contact with the inside of the side wall.
  • This embodiment is particularly advantageous because it allows the side wall to be relatively thin and because both parts can be produced by injection moulding and easily can be assembled to form the finished closure.
  • the inner wall of the closure is preferably concave so as to further increase the pressure within the air space when the inner wall is deformed.
  • the above-mentioned embodiments provide a particularly effective seal between the inner wall and the side wall of the closure when the inner wall comprises an annular extending flange covering the free edge of the side wall.
  • the maximum safe fall distance is about 15 cm for a container comprising a prior art closure and 55 - 60 cm for a container with a closure of the invention.
  • the drawing shows a perspective and partially sectional view of a container comprising a preferred embodiment of the closure of the invention.
  • the drawing shows an open-ended container 1 having at its open end an end flange 2 which is connected with an inclined inwardly extending flange 3 terminating in an annular bead 4.
  • the container also comprises a closure 6 having a plane outer wall 7, a side wall 8 and an outwardly extending inclined flange 9 having at its periphery a flange 10 which is in contact with the flange 3 when the closure 6 is applied to the container 1.
  • the exterior side of the side wall 8 comprises an annular bead 11 which together with the inclined flange 9 form an annular recess for the annular bead 4 on the container.
  • the closure 6 also comprises an inner wall 12 having an annular flange 13 which is airtightly in contact with the inner side of the side wall 8 and an outwardly extening annular flange 14 which fits sealingly to the free edge of the side wall 8.
