Definitions

  • the invention relates to a gastight beverage container according to the preamble of patent claim 1.
  • a can made of plastic film which is suitable and intended for the absorption of liquids. It is a container with a tubular middle part and two bottom parts that end this middle part. Both the middle part and the bottom parts consist of the same foil material made of weldable plastic. The bottom parts have peripheral edge flanges that are welded to the edges of the middle part.
  • this plastic can is neither aroma-tight nor usable for the absorption of CO 2 -containing beverages, because it could not withstand the internal pressurization emanating from such a beverage filling in the long term.
  • a container of the type described above which is constructed from multilayer plastic film with a metallic intermediate layer and is intended for holding pressurized, in particular bubbling liquids and in which a tubular middle part at both ends is completed by welded-in floor parts.
  • the tubular middle part and the bottom parts consist of multilayer composite material with an intermediate layer made of aluminum and in each case an outer cover layer made of plastic.
  • the bottom parts are curved outwards and are delimited by peripheral edge sections, of which cylindrical edge flanges formed by turning a part of originally cylindrical extensions of the mentioned edge sections extend in the direction of the curvature, which abut on areas of the extensions mentioned which are not turned over and point towards the interior of the container.
  • the base parts are connected by welding the outer plastic layer of the edge flanges to the inner layer of the tubular middle part and, moreover, the parts of the edge flanges which are in contact with one another and the non-inverted areas of the extensions adjoining the curvatures of the base parts are welded to one another.
  • the container previously known from this publication is intended for the reception of "bubbling" liquids from which an internal pressurization is emitted, but on the one hand the manufacture and welding of the base parts are very costly in this container and on the other hand there is a risk of a gradual tearing open of the in the type of rolling bellows by turning the originally cylindrical projections edge flanges with welds connecting the edges of the cylindrical central part, in that the edge flanges gradually separate from the edges of the central part under a constant internal pressure exerted by a liquid filling.
  • Such splitting of the weld seams cannot be prevented permanently by the costly double welding of the extensions adjoining the curvatures of the base parts with the sections of the edge flanges adjoining the latter.
  • the invention is intended to create a gas-tight beverage container for the reception of CO 2 -containing beverages which can be produced more cost-effectively than the previously known container and which can permanently withstand an internal pressurization emanating from such a beverage filling.
  • the invention thus relates to a beverage container in which all weld seams are designed as overlap seams and, in view of this configuration, are practically exclusively subjected to thrust due to an internal pressurization from the liquid filling. While in the previously known container according to WO-A-80/02544 there could be a progressive detachment of the edge flanges from the edges of the tubular flanges from the edges of the tubular flanges from the edges of the tubular middle parts under constant internal pressurization, this is due to the practically exclusive stress of the invention realized overlap welds on thrust excluded such a tearing of the welded joints.
  • the beverage container according to the invention is thus characterized on the one hand by a simple and inexpensive production in comparison to the prior art and on the other hand by the fact that it can withstand gas and aroma-tight in the long term as a result of a sensible design, such as that emanating from beverage fillings containing CO 2 .
  • the base parts are curved parts of the shell facing away from the side facing away from the central part or, according to a further development of this configuration, in the manner of spherical caps with adjacent to the latter and welded to the edges of the central part Edge flanges are formed.
  • the central part is rotationally symmetrical with respect to a longitudinal axis.
  • beverage containers designed in this way are distinguished by an excellent resistance Resistance to internal pressures, such as occur with beverage fillings containing CO 2 .
  • one of the bottom parts is welded into the latter at a distance from the one end-side end of the middle part in such a way that the central region of this bottom part which bulges outwards as a result of an internal pressurization emanating from the filling material does not extend over the end-side end of the middle part protrudes.
  • that side of the beverage container on which the base part is welded at a distance from the front end of the central part can form a base for the container.
  • the middle part 11 consists of a film sheet bent into a cylinder jacket, the edges of which adjoin the longitudinal edges overlap one another and are welded to one another in a longitudinal weld seam 12.
  • the base parts 13, 13 ' are designed in the manner of slip covers and have peripheral edge flanges 15, 15' which are adapted to the cylindrical shape of the central part 11.
  • the bottom parts 13, 13 ' are inserted inwards, towards the edge flanges pointing from the cylindrical middle part, into the front ends of the cylindrical middle part and are welded to the front edges of the middle part by means of circumferential weld seams 14, 14'.
  • the film web forming the middle part 11 is a multi-layer composite material which has an internal liquid-tight layer made of a tasteless and weldable plastic, for example made of polyethylene, and a middle layer made of metal foil which, in a known manner, has a vapor barrier that prevents the passage of aroma substances forms.
  • the beverage bag 10 intended for filling with C0 2 -containing beverages is fed with a bottom part 13 welded to its one end end of the middle part 11 to a filling system, filled there with carbonated drink and then closed by welding the further bottom part 13 'to the other end end of the middle part .
  • the beverage container 10 is designed as a pressure container which can withstand the internal pressure which occurs when used as intended.
  • the beverage container 20 differs from the embodiment according to FIGS. 1 and 2 in that the bottom parts 23, 23 'closing the middle part 21 on the front side as shell parts curved outwards, each with an edge flange 25, 25' adapted to the cylindrical middle part and pointing towards the inside of the container. are provided and are welded to the central part in circumferential weld seams 24, 24 'which are also formed as overlap seams.
  • the middle part 21 in turn consists of a film sheet bent into a cylindrical shape, the edges of which adjoin the longitudinal edges overlap one another and are welded to one another in a longitudinal weld seam 22.
  • the bottom part 23 is welded into the middle part 21 at a distance from the one end edge of the cylindrical middle part 21 round weld seam 24, 24 'so that the curvature when the container is under internal pressure of the bottom part 23 does not protrude beyond the end face of the cylindrical middle part adjacent to the circular weld seam 24.
  • 21 connecting circular weld seam 24 extending portion 26 of the middle part forms a base in this embodiment.
  • Characteristic of the beverage containers 10, 20 shown in FIGS. 1 to 4 is their design as a pressure container made of flexible and only low intrinsic stiffness multi-layer composite material, and the intended use for the inclusion of CO 2 -containing drinks.
  • Characteristic of the beverage containers 10, 20 shown in FIGS. 1 to 4 is their design as a pressure container made of flexible and only low intrinsic stiffness multi-layer composite material, and the intended use for the inclusion of CO 2 -containing drinks.
