Definitions

  • the invention relates to a package with a sealing region which comprises a cover which is rigidly connected with the package and a sealing cap which traverses the cover and is held relative to the cover, with both the cover as well as the sealing cap each comprising a discharge opening which can be brought into true alignment and the sealing cap comprising a closing region which can be brought into true alignment with the discharge opening.
  • a package of this kind is known from DE 197 06 112 C2.
  • this known package which is especially described as a beverage can
  • the fluid filled into the can is able to reach between the cover and the sealing cap because the opening in the cover is not sealed prior to applying the sealing cap.
  • Further problems of the known package are the virtually impossible cleaning of soiled covers prior to applying the sealing cap without contaminating the packaged material with detergents or dirt and the highly difficult arrangement of a tamper-evident closure which is understandable to end customers, especially without any additional components.
  • Such packages are especially suitable for pourable or flowable products.
  • this object is achieved in accordance with the invention in such a way that the discharge opening in the cover is sealed by a sealing element which can be brought into an at least partly opened state of the sealing element for discharging the package.
  • the invention is also especially advantageous for the reason that no product particles are present between cover and sealing cap which might lead to a disturbance in the mobility of the sealing cap.
  • the cover which is connected with the package can have any desired shape.
  • the important aspect is that the shape is chosen in such a way that a sealing cap can be moved relative to the cover.
  • an oblong cover is appropriate in which the sealing cap is displaced laterally to the cover.
  • the cover connected with the package is circular. This allows twisting the sealing cap relative to the cover in order to expose or seal the discharge opening.
  • the sealing cap is held to be rotatable.
  • the sealing cap can be fastened with grippers to the cover. For this purpose, individual webs are sufficient in order to arrange functions of the sealing cap there. It is advantageous however when the sealing region comprises a sealing cap which overlaps the entire cover. This helps ensure an especial stability of the sealing cap and offers a large number of possibilities for arranging the sealing cap in order to arrange a large variety of functions there.
  • both the cover and the sealing cap each comprise an off-center discharge opening.
  • the closing area of the sealing cap is associated with a sealing region which encloses the closing area.
  • This sealing region can be arranged both on the cover as well as on the sealing cap. It can lie between cover and sealing cap or be arranged in an integral fashion with the cover and/or the sealing cap.
  • the sealing region comprises a seal.
  • Seals in the present case shall be understood not only as separate seals, but also as seals which are a specially arranged area of the cover or sealing cap which cause a special sealing effect.
  • a special embodiment provides that a lifting apparatus with action between the cover and the sealing cap is provided which causes a removal of the sealing effect of a sealing region between cover and sealing cap on twisting the sealing cap.
  • the sealing element is elastic. This allows a deformation as a result of an overpressure in the package or as a result of an applied pretensioning in the connection of sealing cap and cover.
  • the elastic sealing cap can extend into such opening, if it reaches beneath an opening in the sealing cap. This helps gripping the sealing element or acting with the sealing cap upon the sealing element.
  • the sealing element is bulged outwardly in a cap-like manner with respect to the package in a further development of the invention and comprises at least one flange which protrudes radially to the outside.
  • the outwardly bulging configuration proves to be advantageous for example when a handle for opening the sealing element is provided. It is advantageous when the handle is rigidly connected with the sealing element or is integrated in the sealing cap. After the twisting of the sealing cap to the opened position, the outwardly bulging cap presses through the discharge opening in the sealing cap to the outside, through which the handle for opening of the sealing element can be gripped with greater ease.
  • the transfer of the sealing element to an at least partly opened state will be facilitated when the sealing element comprises a predetermined breaking point. It can be arranged in such a way that the sealing element is opened only partly, or the predetermined breaking point can also permit complete opening of the sealing element.
  • a predetermined breaking point is also advantageous in cases where the handle is integrated in the sealing cap and is arranged especially as a shaped part of the sealing cap and comes into engagement with the sealing element during the twisting of the same.
  • the sealing element can be transferred to an at least partly opened state already during the twisting of the sealing cap, especially in conjunction with the predetermined breaking point.
  • the handle can also be held in movable manner in the sealing cap as a punching tool.
  • the punching tool For opening the sealing element, the punching tool needs to be pressed down to the opened position after the twisting of the sealing cap, through which the sealing cap, depending on the configuration of the blade of the punching tool, is severed either partly or completely.
  • the sealing element can be fixed with a flange to the inside or the outside.
  • An advantageous embodiment is also obtained in such a way that the boundary region of the opening is received in the cover between two flanges of the sealing element.
  • This arrangement is advantageous for the reason because on the one hand the sealing element can be arranged in an especially rigid manner on the cover and on the other hand the upper of the two flanges can enclose the closing area of the same as a seal in the closed position of the sealing cap in this arrangement.
  • This type of arrangement of the sealing comes with the advantage that in this case too there is an intimate connection between seal and cover.
  • the sealing cap comprises in the closing area a recess for receiving the sealing element at least in part, then this is especially advantageous in the case that the sealing element is outwardly bulged in the form of a cap.
  • the sealing element In this at least partly received position of the sealing element in a recess of the sealing cap, the sealing element can be destroyed especially easily for opening during the twisting of the sealing cap.
  • the sealing cap can be made from such a material that it is advantageous to arrange both the seal enclosing the discharge opening as well as the closing area in an integral manner with the sealing cap.
  • both the seal enclosing the discharge opening as well as the closing area is fastened to the sealing cap. It is especially advantageous in this case when the seals are partly embedded in recesses of the sealing cap.
  • the sealing element protrudes with pretensioning into the package after the opening, so that it is unable to cause any disturbance during the discharging of the package.
  • the sealing element comes into engagement with grippers fastened to the sealing cap during the movement of the sealing cap relative to the cover. This allows keeping a severed or severable part of the sealing element on the sealing cap, so that it can fall neither into the package nor anywhere into the ambient environment.
  • the grippers can grip the sealing element or at least a part of the sealing element prior to its severing, hold the same during the severing and preferably even hold the same after its severing.
  • sealing element is latched to the sealing cap after the opening. In this way, the sealing element or the severed part of the sealing element will hang rigidly on the sealing cap, where it is held in a manner as captive as possible.
  • the lifting apparatus comprises a latching cam arranged on the cover or the sealing cap and a latching recess arranged on the respectively associated part, with the latching cam and the cooperating latching recess determining by their geometric arrangement the two positions of the sealing cap in which the two discharge openings on the one hand and the closing area of the sealing cap on the other hand are in alignment with the discharge opening in the cover.
  • This arrangement ensures not only the necessary lifting of the sealing cap during the movement of the sealing cap relative to the cover, but the two operating positions of the sealing cap are determined simultaneously, so that it is ensured that in the one position the package is completely opened and in the other position completely closed.
  • a second opening is provided in a further embodiment of the invention which is sealed by a second, preferably elastic sealing element. This second opening is used as a venting opening when the sealing element has been destroyed.
  • the sealing cap is provided with a projection which penetrates the second sealing element in the opened position of the sealing cap and opens the same.
  • the sealing cap comprises a further sealing region which seals a second sealing element in the closed position.
  • the second sealing element which is usually used as a venting means during the discharge of fluids, is opened after its opening and thus allows fluid to exit.
  • the further sealing region which is preferably arranged as a sealing allows sealing the opened second sealing element, especially when the can is closed.
  • the sealing cap comprises a blade.
  • a simple embodiment provides that the blade is arranged in the discharge opening.
  • the sealing element When the sealing element enters the discharge opening, it can be cut off with the blade. Subsequently, the sealing cap is turn slightly back again, whereupon the content of the package can pass out of the discharge opening.
  • a simple embodiment provides that the further opening is an oblong hole. This allows a sealing element which is in alignment with the oblong hole to enter the opening and to open the sealing element by a motion of the sealing cap relative to the cover.
  • An especially simple cooperation between a blade fixed to the sealing cap and a seal is achieved in such a way that a portion of the pretensioned seal protrudes into an opening of the sealing cap during a movement of the sealing cap relative to the cover.
  • the seal can be pretensioned here by a special deformation or be under a pretension by the pressure of the sealing cap against the seal until the seal protrudes into an opening of the sealing cap.
  • the part of the pretensioned seal audibly jumps into a position during the motion of the sealing cap relative to the cover, especially an opening of the sealing cap.
  • the seal jumps into the opening with a “plop” sound in which it is subsequently cut off by a motion of the sealing cap relative to the cover.
  • An acoustic signal can also be achieved in that the seal jumps into a recess in the sealing cap and thus indicates, preferably in an audible way, a special position of the cover relative to the sealing cap.
  • the sealing element comprises a circumferential weakened portion for the engagement of the blade.
  • the sealing cap can comprise an opening with a cover.
  • the cover then forms a cavity for receiving at least a portion of the seal.
  • This cover can be arranged integrally with the sealing cap or be connected with the same as an additional part. It can preferably be provided that the opening with the blade comprises a cover.
  • the seal and the discharge opening in the sealing cap are arranged in such a way that the seal is unable to penetrate the discharge opening.
  • the sealing cap can be moved in only one direction relative to the cover.
  • sealing cap is made from a multi-component material. This allows providing especially strong materials for connecting sealing cap and cover, whereas other qualities of the material are required for the sealing regions.
  • sealing cap comprises a metal frame with a plastic insert.
  • Elasticity of the sealing element is not necessary for many embodiments. It is advantageous however when the sealing element can be deformed for sitting close to the sealing cap. This allows support the sealing element with the sealing cap in the closed state.
  • the sealing element comprises a frame which seals against the sealing cap.
  • the sealing element comprises a bellows. This allows pressing a portion of the sealing element in a simple manner into the package or to extend a portion of the sealing element as a spout for example.
  • the sealing element comprises a film hinge.
  • a film hinge or several film hinges enable the provision of predetermined bending points with which a bellows can be produced or which enable a defined deformation of the sealing element.
