Definitions

  • the invention relates to a container with cover, both made from plastics, which container can be hermetically closed by providing a seal between two engaging flanges of the container and the cover respectively, and can subsequently be opened by breaking a thin wall section in the container flange.
  • a disadvantage of this known container and cover is that much room is needed to pack these containers, whether filled or empty, on account of the horizontal flanges projecting outwardly from the container.
  • Another disadvantage is the fact that the outwardly projecting horizontal flanges are sensitive to thrusts in vertical direction, especially in upward direction, which may result in unintentional breakage of at least part of the thin wall section, the hermetic seal being thereby broken.
  • Yet another disadvantage of the said container and cover combination is that, although after breakage of the seal between the container and the cover and removal of the cover the cover can be wedged onto the container again, the combination with the wedged closure is less reliable under certain conditions.
  • the object of the invention is to provide a container and cover in which the disadvantages mentioned are avoided.
  • the container flange comprising a substantially vertical auxiliary wall, at some distance from the container and externally around the container, which extends along some height in the upper region of the container and which is connected to the container wall by a circumferential connecting wall, the auxiliary wall having a thin wall section beneath the junction with the connecting wall, and by the flange of the cover being formed by a skirt of a hooded cover, which skirt, in the case of a closed container, envelops the auxiliary wall and extends beyond the thin wall section in such a way that below the thin wall section there are two contiguous flange sections of the container and the cover respectively, between which a seal can be provided.
  • the cover When, with a container and cover designed in this way, the cover has been removed from the container after severage at the thin wall section, it can be placed on the container again, the part of the container flange that was originally located below the thin wall section and that now is part of the cover gripping under the part of the container flange that has remained intact. In this way, even after . severage at the thin wall section, which renders the seal ineffective as a means to fasten the cover to the container, still a good grip of the cover on the container is obtained. Further, on account of the vertical position of the flanges room is saved and the thin wall section is less likely to break when upward or downward forces are exerted on the cover.
  • the thin wall section is located on the inside of the auxiliary wall and the inside of the cover flange wall is provided with a circumferential, continuous or discontinuous rib, which, when the container is closed, interacts with the upper wall of a groove present on the outside of the container flange wall as a result of the thinning of the wall.
  • the auxiliary wall may at its top edge be connected to the container wall by means of the connecting wall. No dirt can then collect between the auxiliary wall and the container wall.
  • An advantageous arrangement is that in which the connecting wall is between the top edges of the auxiliary wall and the container wall. In this way, a reinforcement of the opening rim of the container is obtained.
  • the groove necessary to obtain the thin wall section is not provided until after the container has been moulded.
  • An injection moulded container for example, may by cutting or milling be provided with a groove defining a thin wall section.
  • the advantage of not providing the groove until a later stage, e.g. at the user/filler, is that the auxiliary wall is less delicate between injection moulding and use/filling.
  • the user/filler may provide the groove before filling, after filling or after application of the cover.
  • the groove may be provided simultaneously with the seal. Providing the groove after the cover has been placed on the container is preferred in those embodiments in which the thin wall section is on the outside of the auxiliary wall.
  • the weld may be obtained by adhesive or heat sealing.
  • the container and the cover may be designed with a round, oval, triangular or rectangular horizontal cross section.
  • the container 1 has a bottom 2 and a side wall 3.
  • a substantially vertical auxiliary wall 4 is connected to the container wall 3 by a connecting wall 5.
  • the cover generally designated by 8, has a downwardly extending skirt 9 which envelops the auxiliary wall 4 and extends beyond the thin wall section.
  • a seal 13 has been applied between the flange part 10 of the cover and the flange part 11 of the auxiliary wall.
  • the embodiment according to Fig. 2 has a connecting wall 5 between the top edges 14 and 15 of the auxiliary wall 4 and the container wall 3 respectively.
  • the assembly functions as described for Fig. 1.
  • the free end of the cover skirt may be provided with an inwardly directed gripping flange, which grips under the auxiliary wall.
  • the user may or may not use a seal, at his discretion.
  • the inwardly directed flange is indicated by the interrupted line 16 in Fig. 2.
  • auxiliary wall 4 in which a thin wall section 17 has been provided by means of a stepped-out arrangement of part 11 of the auxiliary wall. After breaking of the thin wall section 17, the part 11 can grip under the remaining upper part 12 of the auxiliary wall.
  • Fig. 4 shows an auxiliary wall 4 with a circumferential groove 18 on its outside, with which a circumferential rib 19, on the inside of the cover flange 9, can interact.
  • Fig. 5 represents a variation in which the thin wall section 20 is on the inside of the auxiliary wall 4.
  • the resulting groove 21 on the outside of the auxiliary wall 4 has a ring-shaped upper face 22 with which the rib all around the inside of the cover flange 9 engages.
  • the radial partitions 24 as drawn in the Figs. 1-5 increase the stiffness of the auxiliary wall above the thin wall section. This is advantageous because this part of the auxiliary wall can resist the forces occurring during severage, so that severage is easier.
  • the container and cover are so designed that they can be injection moulded using simple moulds that open and close in one line.
  • the container and cover may be made from the same injection mouldable plastic or from different plastics, for example polyethylene, polypropylene, copolymers of ethylene and propylene or mixtures of these (co)polymers.
