Definitions

  • the invention relates to a box according to the preamble of the claim, a method for manufacturing a box according to the preamble of claim 11 and to an apparatus for manufacturing a box according to the preamble of claim 15.
  • Cans with a lid which can be pressed in on the lid, in particular beverage cans, are in two or three parts.
  • a cylindrical can body is provided by deep drawing.
  • a lid with an opening device for opening the pressable opening is arranged at the open or upper can end.
  • the can jacket or the can wall has a longitudinal seam and before filling the can, a bottom is arranged on an end face of the jacket. For fastening the bottom and / or the lid often Falztheticen but also welded joints are used.
  • a constriction and a contact region are formed at the upper end side of the can jacket, wherein the contact region is adapted to a corresponding contact region of the can lid.
  • the can lid is connected to the jacket with a folded seam or a weld, in particular a laser seam.
  • Designs with a seam seam are very widespread, it being apparent from WO 2003/059764 A1 that a ring area must be free and accessible radially inside the seam connection so that a support element necessary for the formation of the seam can be arranged there.
  • Embodiments with laser connections are known, for example, from WO 2005/000498 A1 and WO 2009/155721 A1.
  • the upper end of the can jacket assigned to the can lid is narrowed by upset necking or spin-flow necking, wherein in addition the form of the contact region necessary for the connection to the can lid is formed.
  • the contact region comprises, for example, an open can end which is formed with a radial portion outwards or inwards.
  • the constriction and / or the contact region can also be formed with a pressing step on a mold. Because the expansion is easier compared to the narrowing, for example, a Form step are carried out according to WO 2005/068127 A1, in which the can jacket is pressed by a pressing element, in particular a hose element can be filled with pressurized fluid, radially outwardly to an inner mold.
  • a beverage can in which the tear-open tab is rotatably mounted on the can lid and on the lid facing the underside has a closure element, which after opening the can and turning the tear-open by 180 ° to the opening lie comes.
  • the necessary for the closure of the open can opening and re-releasing the can opening rotating the tear-open tab by 180 ° is complex. Because a tear-open tab only associates the tearing motion, the users will barely perform the rotary motion necessary to re-close.
  • a sleeve is known, which is placed with respect to the can axis from the radial outside on the tear tab of a beverage can and clamped at the outer end with a circumferential bead surrounding the groove onmonsvons hem.
  • the attachment takes place before or after opening the box.
  • An uptake before opening is associated with a particularly great effort, because yes, the tear-open tab must be taken in the lid depression and must be bent upwards so that it protrudes beyond the rabbet connection and thereby allows the insertion of the sleeve without an unwanted opening of the Can effect.
  • a plugged sleeve can be rotated around the can axis over the pressed can opening and close it.
  • the arrangement of the sleeve on the pull tab and the clamping on the peripheral beading a relatively tight closure of the opened can opening can be achieved.
  • the attachment of the sleeve to a finished box with a tear-open is very expensive. If the sleeve is placed prior to opening the can, the engagement of the rabbet joint obstructs movement to open the can.
  • the present invention has for its object to find a solution with the doses can be easily made with a lid formed on the depressible opening and the opening of the cans easy, especially with one hand, is feasible.

  • the tamper-free contact ensures that the opening movement can be carried out without overcoming an increased initial resistance.
  • the feature of non-invasive contact does not preclude solutions in which an extremely small distance is formed between the outer end of the push lever and the outer end face of the protruding annular region.
  • This feature defines the close spatial relationship between the outer end region of the push lever and the protruding annular region and the avoidance of a clamping engagement. Because the outer end of the press lever before the opening movement, the outer end surface of the projecting ring portion without interference, so no increased initial resistance must be overcome when opening the can.
  • the position of the outer end of the pusher lever is chosen so that it can be pressed well with a finger from the radial outside and still the risk of unintentional Aufreissens is extremely small. It has been found that the same radial distance as between the can axis and the radially outer layer of the outer end face of the projecting annular region already suffices to allow a desired pressing. It goes without saying that the outer end of the push lever can also protrude slightly beyond the radially outer layer of the outer end face. The outer end is then formed at the outer end face of the projecting ring portion so that it can be easily moved away from the outer end face. Radially outside the outer end face, the outer end of the push lever thus does not engage with the projecting annular area.

  • the two laterally outwardly leading portions of the pusher lever 7 are annularly connected to each other at the outer end 7a.
  • two laterally outwardly leading regions of the pressing lever 7 extend over the projecting annular region 10, and outside the projecting annular region 10 they are connected to one another annularly at the outer end 7a.
  • the push lever 7 can be gripped at the annular outer end 7a with a finger and moved from the position according to FIG. 13 into the position according to FIG. 14. In this case, the depressible opening 6 is pressed in by the inner end 7b of the pressing lever 7.
  • the ring portion of the pusher lever 7 also has a strong design effect. It is pronounced of the previously used in bottles strap closures with an annular operating handle. In order to increase the design effect even further, a recess 3a is optionally formed in the can jacket 3 for partially receiving the annular outer end 7a of the pressing lever 7.

Abstract

L'invention concerne une boîte (1) comprenant une enveloppe (3) fermée autour d'un axe (2) de la boîte, ainsi qu'un couvercle (4) fixé à cette enveloppe (3) dans une région de liaison (5, 19, 20) et pourvu d'une ouverture à enfoncer (6), un levier de pression (7) étant fixé au couvercle (4) en un point de fixation (9). Cette boîte (1) présente au niveau du couvercle (4) une zone annulaire (10) faisant saillie par rapport à la boîte (1) en direction de l'axe (2) de la boîte et présentant une surface frontale extérieure (10a), ainsi qu'un évidement (11) situé à l'intérieur de cette zone annulaire (10) en saillie. L'ouverture à enfoncer (6) peut être ouverte par un mouvement d'ouverture par pivotement du levier de pression (7) autour d'un axe de pivotement au niveau du point de fixation (9). Lorsque la boîte (1) est prête à être ouverte, le levier de pression (7) s'étend radialement dans l'évidement (11) à partir de l'axe (2) de la boîte jusqu'à la zone annulaire (10) en saillie du couvercle (4), et une extrémité extérieure (7a) du levier de pression (7) est en contact avec la surface frontale extérieure (10a) de la zone annulaire (10) en saillie, sans venir en prise avec ladite surface, de sorte que, pour ouvrir la boîte (1), le levier de pression (7) peut être relevé par rapport au couvercle (4) par son extrémité extérieure (7a) à l'aide d'un doigt déplacé depuis l'extérieur radialement contre la zone annulaire (10) en saillie.
