Definitions

  • the invention is concerned with a beverage can which is to be described as a thin-walled can.
  • these beverage cans are generally made from sheet metal with a wall thickness of less than 0.24 mm.
  • beverage cans i.e. thin-walled cans for receiving a beverage, preferably a carbonated beverage, with which the can is additionally stabilized due to the internal pressure after it has been closed, so that it does not or only prevents mechanical deformations from the outside (caused by the user's hand) is insignificantly deformable.
  • straws are known as drinking aids, which are inserted into a container which can be explained as an elastically deformable bottle made of plastic.
  • the straw used is kinked, has a fold-shaped bellows at the kink and is mechanically clamped at the edge of the filling opening for filling through the drinking opening, cf. there abstract and page 2, section 32.
  • the pretension of the drinking aid can be released by mechanically deforming the bottle, the drinking straw abutting the inner side of the cap closure.
  • the drinking opening and the filling opening are the same openings, and the straw is also inserted through this drinking opening into the interior of the container.
  • the object of the invention is to improve conventional beverage cans with regard to several known and long-standing disadvantages.
  • these disadvantages individually or in combination, are those mentioned below.
  • the known beverage cans are not resealable. When consuming the last remainder of the beverage content, it is not possible to drink well from the beverage cans
  • the cans according to the invention do not lose their stackability.
  • the filling takes place in the manner of a normal can filling, so that production lines do not have to be changed over.
  • Protection against overpressure can be achieved when the thread is opened for the first time by interrupting the thread with an axial groove, thereby preventing the cover from being shot away when it is opened.
  • the reclosable opening lies in an end section which is in particular domed inwards (claim 1), in particular essentially in the center thereof.
  • this section corresponds to a retracted base section, so that the closure cap can be surrounded by a stand-up ring which engages in a correspondingly encased design of an overlying end section of a stacked can in order to
  • the necked-in end section corresponds to that section which contains an opening system, but is here designed without an opening system.
  • the opening system according to the invention is resealable and is located in a bottom section.
  • the usual beverage can is used inverted by the user, but not inverted when filling.
  • the reclosability can be realized by a cap that does not impair the stackability of the can (claims 17 to 19).
  • a drinking aid can be included in the thin-walled can as a container together with the contents. It moves out of the container after the opening, the opening from which the drinking aid emerges when opening is not the opening through which the thin-walled can was filled, rather the drinking aid is moved out at that end section of the thin-walled can which opposite the person filling.
  • the driving out of the straw (as a drinking aid) due to the mechanical tension added to the straw occurs automatically during opening and does not have to be taken into account by the user.
  • the opening provided for moving the drinking aid is reclosable (claim 10).
  • the reclosure with the cap ensures that the drinking aid is pushed back into the interior of the container and the pretension can be built up again.
  • a reopening of the reclosable container ensures that the drinking aid reappears due to the stored (mechanical) energy, irrespective of the amount still left in the can.
  • the invention thus has significant advantages over solutions of the prior art in which the movement of a drinking aid is only effected by buoyancy forces of the liquid.
  • the closure with the closure device is done in such a way that the closure device is placed on an insert part, locked by a rotary movement and thus re-closed, which insert part in one of the
  • the drinking aid preferably as a drinking straw (claim 13)
  • the drinking aid can be guided laterally, which radial guidance does not have to be direct contact (claim 16), but can ensure that when opening the drinking aid is reliably released from the opening Drinking opening emerges essentially axially. Air can flow between the straw and the guide when drinking.
  • the guide for the drinking aid is arranged near this opening, in particular in axial alignment or even in this opening (claim 11) in order to allow the spatial / geometrical assignment of the drinking aid to the exposed opening section and at the same time to promote filling of the beverage can earlier in time ,
  • the filling takes place in the manner of a can filling in a filling line, the initially larger opening (the open end of the body) serving for filling the drink, this opening then being closed with a lid provided without a locking system on a folded edge (claim 1).
  • the user can remove the drink via an inserted drinking aid at the opposite end by using the previously described reclosure system (claims 6, 7).
  • the guide is designed so that it works well and with little friction together with a straight section of the drinking aid.
  • An intermediate stop on the drinking aid can prevent the mechanical pretension from driving the drinking aid too far out of the interior of the thin-walled can.
  • the bias can be provided as an internal residual stress of the drinking aid (claim 14). This can be achieved by an at least sectionally spiral shape in the interior of the can or a bend, diffraction or a bellows-shaped section.
  • the drinking aid does not have to be passed through the consumption opening, but can first be introduced through the larger opening of the fuselage, which is open on one side, with the opposite end closed with the reclosable removal opening.
  • the can is filled through the same opening, with a subsequent closing of this opening via a fold section.
  • the larger opening closed in this way can no longer be opened by hand, rather the opposite - reclosable - opening is provided for the user.
  • This opening is closed during filling, so that the drinking aid at this opening is blocked for an outlet during filling (claim 7).
  • the drinking aid can be fixed at the opening that is used for filling by a special form of installation of the end of the drinking aid on this side. The mechanical pre-tension is already brought into the drinking aid.
  • the drinking aid is put under tension when it is filled and can receive this tension again when the user closes the reclosable drinking opening.
  • the function of the filling opening as an open fuselage end and its closing with a beverage can lid can be seen.
  • the container which has not yet been closed is the subject of claim 1 as a thin-walled can, for use in an intended method, but oriented towards the manufacturer of the can according to claim 1, which are supplied to the bottler for use.
  • Thin-walled containers can already be provided with a pretensioned drinking aid so that it does not jump out of the container and is completely absorbed by the container, the drinking aid being supported near the open end in order not to hinder the filling.
  • the drinking aid can also be inserted by the user after opening.
  • a reclosable closure is arranged, the guidance of which is suitable for guiding the drinking aid at the later opening by the user at this point, for example controlling a driving out and allowing the uncovered opening to be closed again and the pretension to build up again in the drinking aid.
  • the insertion is also guided laterally. This is based on the user who has the (filled) can according to claim 5 in front of him and can use it in the manner described in claim 6. But can also introduce a stalk for the first time.

  • the cap-shaped closure 3 can also be changed in diameter. For example, it can be made larger than in the form shown in FIG. 1b or 1a, in which it each has a smaller diameter than the intermediate section 1c of the beverage can.
  • the last-mentioned section is formed into a folded edge F (for example a double fold closure), which is then also designed to be pressure-tight.
  • the pressure component built up in the can after closing is greater than the external pressure, so that an additional mechanical stabilization occurs which secures against mechanical deformation of the cylindrical section 1c. If there is mechanical stability, the drinking aid cannot be changed in its inner position with its lower end or with its remaining sections in the filled state, unless the closure 3 is opened, which leads to an axial upward movement of the drinking aid.
  • the straw is secured or fixed, on the one hand at the reclosable end 2 (by contacting the inside of the cap 3) and on the other hand by supporting and non-slipping contact of the end 17b near the open end, through which the can filling is to take place at the bottler.
  • the bottler fills the can as it is delivered to him, without having to change his filling line. It is practically unaffected by the fact that the supplied beverage can already has an inserted drinking aid that does not protrude axially and therefore the Filling can not hinder.
  • the can is filled in the normal process, as are customary beverage cans which have no drinking aid and no reclosable opening in the dome-shaped base section 1a ".
  • the drinking aid has a residual stress already specified by the manufacturer of the preform, which can be applied and used by the user (after filling).
  • the energy is stored by locking the reclosable end, the filling has no effect on it.
  • the fixation of the straw at the other end can be improved in that more than just one contact point is made available, for example a pitch circle which rests on the retracted upper end, as can be seen from FIG.
  • the pitch circle has a larger diameter than the opening 10 with its diameter dio in order to prevent the stalk 17 under tension from slipping out with its tension end.
  • connection technique is used that is tight against pressure and liquid, such as gluing, sealing or a sealing compound or sealing rings that are used.
  • a snap lock is also possible with an additional pressurized seal to seal against excess pressure.
  • Direct injection molding into the opening 11 is also possible. The molding can take place from the outside axially or from the inside axially.
  • the straw 17 can be 10% to 50% longer than the axial extent of the beverage can. If a helix or a partial helix is provided as an "at least sectionally spiral" design, the number of revolutions (in the ⁇ direction) can be selected between 0.5 and 3. In exceptional cases, a winding size of up to five
  • the spiral configuration does not necessarily have to be symmetrical, that is to say have the same axial extent of the 360 ° turn of a respective helical section.
  • a circle formed in this way can no longer emerge from the filling opening 10 under tension because it comes from the neck 1c" in the can Inside I is kept.
  • the previously described sections of the drinking aid are to be added.
  • the drinking aid 17 has the described tension section with the support end 17b and has the described exit section 17e with the drinking end 17a. In between there is a bend section 17d which applies the prestress.
  • This section can be pre-bent, can have a bellows or can be designed in the form of an at least partially circumferential spiral 17d '(oriented in the z-direction and ⁇ -direction of the cylinder coordinates).
  • the contact point of the free end 17b or 17b' lies at a more or less small distance g or h from the folded edge of the can body which has not yet been closed.
  • the three influencing parameters mentioned are matched to one another in such a way that the purpose described above is achieved.
  • the angle is chosen appropriately, the contact point at a distance g, h from the fold edge 1c * is chosen so that the contact point is close to the fold edge, and the specific spatial design of the tension end 17d of the drinking aid 17 is also matched to this.
  • the inner channel 17c of the drinking aid which can be seen from the figures. It extends between one end 17b and drinking end 17a and is continuous.
  • the fixed arrangement can be released by the influence of mechanical forces if it is desired to pull out the straw 17 after use and to empty it for purposes of separate disposal.
  • a vigorous pull on the linear guide section 17e leads to a shearing or separation of the stopper 19, which can be designed as a ring, and allows this Pulling out the entire straw 17, including its tension end through the only remaining opening when the cap 3 is removed. Without such shearing and a pulling of the straw provided with higher forces, touching the linear section 17e is not necessary for the straw to emerge, rather it becomes Movement of the internal tension fulfilled by itself, but limited by the stopper 19 described, which strikes the guide 4 or 4c in such a way that the expulsion movement is stopped.
