Definitions

  • the invention relates to a can according to the preamble of claim 1.
  • Cans come for example for food, beverages or the like. to use.
  • a major problem with such cans is that the emptied cans have so far been sent to household waste or to recycling in essentially unchanged form.
  • the emptied cans form a bulky good, which is why half an attempt is often made to compress the emptied cans at least on their jacket part in order to reduce their volume. Due to the bottom connected to the jacket part, however, when the jacket part is pressed together due to the rigidity of the bottom, there is hardly any possibility of compressing the empty box very space-saving or at least approximately flat.
  • a can of the type mentioned is known from US-A 2 783 934.
  • the jacket part is formed with tabs which protrude axially from both the upper and the lower edge of the jacket part.
  • the base and the lid of this box have a base part with a peripheral contour that is adapted to the peripheral contour of the jacket part.
  • longitudinal slots are formed along the peripheral edge of the base or the cover, through which the tabs protruding from the cover part are inserted when the base and cover are fixed to the cover part.
  • the tabs inserted through the longitudinal slots then become part of the jacket bent, after which a band is arranged, which is provided for fixing the tabs on the jacket part.
  • US Pat. No. 3,179,321 describes a container with a bottom, a jacket part and a lid, the bottom and the lid closing the jacket part on the top and bottom.
  • This container is formed on the upper edge of the jacket part with tabs with which it is possible to detachably or tightly arrange the lid on the jacket part.
  • the bottom of this container is not intended to be detached from the jacket part; rather, the bottom is fixed there, for example by means of rivets, and thus virtually inseparably on the lower edge of the jacket part.
  • DE-A 4 006 193 shows a screw jar that not only has a screw cap, but also a screw bottom. Space-saving disposal is not possible with such a screw-on jar because it cannot be squeezed to save space. This applies in particular to the two closures of this known screw jar.
  • the invention has for its object to provide a can of the type mentioned, which is simple and inexpensive to manufacture, and which can be easily converted into a small volume in a drained state without additional tools, so that it can be disposed of in an environmentally friendly manner.
  • the predetermined breaking line of the corresponding ring-pull opening device expediently runs in the immediate vicinity of the peripheral edge or the peripheral contour of the bottom or lid, so that after opening the bottom and the lid, respectively remaining bottom or lid edge is as narrow as possible and consequently does not cause any undesirable buckling stiffness for the casing part.
  • the tear-off tape opening device is provided on the casing part in the vicinity of the bottom and the lid in the case of the can according to the invention.
  • the contents in the can can be emptied from the can easily and without remaining residues.
  • the casing part can e.g. after opening the bottom and the lid or after removing the bottom and the lid can be squeezed or pressed flat with the palm of your hand or with one foot.
  • the emptied can has the smallest possible volume, which is also advantageous, for example, for refuse collection, for transport to a landfill, or for recycling.
  • the flattened cans including or exclusive bottom and lid e.g. like collecting magazines and recycling them.
  • the ability to flatten the cans easily and effortlessly means that there is a high level of motivation for collecting waste cans.
  • FIG. 1 shows a can 10, partly in section, in a side view, the can 10 having any base shape.
  • a can 10 usually has a circular, oval, rounded polygonal or any other base shape.
  • the can 10 has a jacket part 12 which is closed at the top by a lid 14 and at the bottom by a bottom 16 as soon as the can 10 is filled with content.
  • the sealing arrangement of bottom 16 and cover 14 on the casing part 12 is known and is not the subject of the present invention, so that there is no need to go into this in detail.
  • Both the lid 14 and the bottom 16 are provided with an opening device 18 in the box 10, which - as can be seen from FIG. 2 - are designed as a ring-pull opening device. They have a ring 20 and a tear-open claw 22 in a manner known per se and are fixed, for example, to the cover 14 or to the base 16 by means of a rivet 24. If the corresponding ring 20 is pulled up, the tear-open claw 22 is simultaneously pressed into the cover 14 or the bottom 16.
  • a predetermined breaking line 25 in the immediate vicinity of the edge of the bottom 16 or lid 14 serves to tear off the lid 14 or the bottom 16 along the corresponding predetermined breaking line 24 in a force-saving manner.
  • the predetermined breaking line 25 is provided in relation to the associated opening device 18 in such a way that the corresponding tear-open claw 22 is inserted into the predetermined breaking line 25 when the ring 20 is pulled up.
  • FIG. 3 Another embodiment of the can 10 according to the invention is shown in FIG. 3 in a side view.
  • the box 10 shown here has opening devices 18 on the jacket part 12 in the vicinity of the base 16 and the lid 14, which are designed as tear-off tape opening devices known per se with a tear-off tape 26 running around the jacket part 12.
  • Each tear strip 26 has a freely accessible end section 28, which is gripped in order to be able to tear off the corresponding tear-off tape from the jacket part 12 of the can 10.
  • the jacket part 12 can be formed in the immediate vicinity of the corresponding tear-off tape 26 with circumferential predetermined breaking lines 30.
  • the opening devices 18 on the bottom 16 and on the lid 14 of the can 10 also have the advantage that both opening devices 18 can be actuated without problems, without the reduced stiffness of the can 10 after actuation of an opening device 18 affecting the operability of the remaining second opening device 18 adversely affects.
  • both opening devices 18 can be actuated without problems, without the reduced stiffness of the can 10 after actuation of an opening device 18 affecting the operability of the remaining second opening device 18 adversely affects.
