Definitions

  • Container with side wall, cover and tearing device produced as a unit.
  • the invention relates to a container with side wall, cover and tearing device for the cover produced as a unit to be closed after filling by means of a separately produced bottom.
  • the tearing device of the known container unit is a circular tearing strip situated in the upper top face of the container.
  • the tearing strip is bordered by- weakening lines in the material and has. a grip ring by means of which the ringshaped strip and that part of the closure surrounded by the strip can be torn from. the container. After the opening of the container a lid can be put on the upper protruding ridge around the aperture.
  • the known container offers important advantages as it consists of only two separate units viz. a container unit and a bottom unit, which units after filling from the bottom are united suitably by friction welding. The container is opened by pulling the ring in the axial direction and after the tearing of the closure the separate lid can be put on.
  • the present invention is based on the recognition that in spite of the advantages of the known container in relation to those known previously it suffers from a number of disadvantages in the production as well as in use.
  • the invention aims at the solving of the problem to devise. a container construction, which is less resource demanding, simpler to produce and more consumer-friendly.
  • the problem is solved thereby that the tearing device is a circumventing tearing strip around the container wall between its upper edge and the lower edge of a frame around the closure, which after the removal of the tearing strip is adapted to fit into the upper edge zone of the container wall as a reusable lid.
  • the closure and the lid are combined to a single part, whereby the resource consumption becomes less. Further, a circumferential protruding edge around the container opening, which in the known construction is necessary for several reasons, is avoided. This also reduces the consumption of material, especially in the case of containers having large openings, for example buckets or tins for paint.
  • the container according to the invention offers the advantage that the material, which normally is introduced into the mould at a place situated centrally in the top surface of the closure, shall not move upwards as well as downwards when it is leaving the surface of the closure.
  • the frame of the lid and the upper edge area of the container wall have mutually complementary holding means resulting in the necessity of exerting greater force by the removal of the lid, so that the risk that the lid falls off, if the con- tainer is tipped over, is less.
  • the holding means can be corresponding circumferential protrusions contacting each other with spring-lock effect.
  • the tearing strip has an integral pulling member offering a safe grip for exerting a radial pull in the tearing strip.
  • a radial pull will in general give a better control over the opening procedure than the axial pull, which is to be exerted in connection with the known container.
  • the container unit is suitably designed, so that the upper, surface of the lid at least in some places protrude beyond the frame to form a grip for the fingers.
  • the construction according to the invention opens up the possibility in a simple way to produce a sealing, so that the consumer can check whether the container has been opened before.
  • This is expediently obtained by means of a sealing string produced integrally with the lid and the pulling device, which string automatically tears when the pulling device is actuated for opening of the container.
  • a sealing string produced integrally with the lid and the pulling device, which string automatically tears when the pulling device is actuated for opening of the container.
  • Fig. 1 shows a container unit according to the invention seen in perspective
  • Fig. 2 a longitudinal cross-section of a container unit according to the invention with closure and container wall and tearing strip between closure and wall,
  • Fig. 3 an axial cross-section through a separate bottom to be put on the container unit
  • Fig. 4 an axial cross-section through two container units stacked one into the other
  • Fig. 5 an axial cross-section through a container unit with mounted bottom and with the container lid put on the container after removal of the tearing strip, arid Fig. 6 two with bottom assembled containers stacked one upon the other.
  • the drawing shows a container with a lid 1 and a tapering side wall 4 and a bottom 3.
  • the container is produced by injection moulding of plastics in two units, one of which is shown in Figs. 1 and 2 and comprises the closure 1, the wall 2 and the intermediate tearing strip 4 with a pulling flap 5, by means of which the closure 1 can be removed from the container wall 2.
  • the tearing strip 4 is produced with weakening lines 6, which can be more or less discontinuous in order to create suitable flowing paths for the plastics between closure and wall during the moulding.
  • a circumferential -frame 7 On the under side of the lid 1 is a circumferential -frame 7 having an outwardly projecting wedge shaped rib or bead 8 the whole way around and designed for meshing the lower edge 9 of a narrowed edge zone 10 in the upper part of the container wall 2 when the lid after removal of the tearing strip is put on the container.
  • FIG. 2 is designed with an inward going part 12 forming a shoulder 13 against which the flange 11 of the lid can rest when several container units are stacked within each other as shown in Fig. 4 in the usual way to save room by the storing and transport of this kind of container units.
  • a sealing string 14 which is broken when the tearing strip 4 is removed by pull in the pulling flap.
  • the sealing string 14 is weakened at the pulling flap so that after having been broken it remains on the flange 7 as shown in Fig. 5, thereby indicating that the container has been opened even if the lid 1 rests on and closes the container.
  • the flange 7 and the narrowed upper part of the container form a space for the pulling flap 5 so that this does not get in the way by the stacking of the container units.
  • the container wall 2 has below a circumferential groove 15 corresponding to an upwards protruding rib 16 along the circumference of the bottom 3 as can be seen in Fig. 3.
  • the bottom 3 is put on the container unit with the rib 16 within the groove 15, and these units are welded together preferably by friction welding.
  • the bottom 3 has a depression 17, Fig. 3, which corresponds to the top surface of the lid inclusive the flange 7, so that filled containers can be put one upon the other in a stable stack as shown in Fig. 6.
  • the container units can be filled up to a volume corresponding to the lower edge of the tearing strip 4 on the complete container even with a foaming fluid owing to the auxiliary container volume derived from the height of the tearing strip and the frame 7.
