Definitions

  • the present invention relates to a single piece reclosable opening member according to the preamble of claim 1 for pouring liquids from packaging containers.
  • the invention relates to reclosable opening members which have a lid for reclosure and which are initially opened by pulling up the lid.
  • the pulling-up motion of the lid actuates opening of a designated opening aperture in the container. This is achieved by pushing down the material of the designated opening aperture into the container, thereby separating it from the container and lifting it out of the container when pulling up the lid.
  • This preferred embodiment achieves initial opening in one single motion.
  • the present invention relates to the above described opening member in combination with an aseptic laminate container having a designated opening aperture which is provided by substantially weakening the laminate material around the circumference of the designated opening aperture. This weakening can be achieved by eliminating or cutting of the structural stability layer which is usually sandwiched between two barrier layers to form a liquid tight laminate material for liquid packaging containers.
  • the opening member in combination with an aseptic laminate container is particularly useful for packaging non-carbonated beverages including milk, fruit juices, nectars or fruit juice drinks.
  • Opening devices for disposable packaging containers for liquids are well known and have been developed over a long period.
  • DE 2232799 discloses so called gable top cartons as packaging for liquids. The opening is provided by tearing off one side of the top of the gable, thereby creating a pouring spout. This package does not provide reclosure and requires considerable strength or a cutting tool for opening.
  • DE 2407345 discloses flat top packaging for liquids. The opening is a hole, cut out of the flat top which is sealed with a plastic film before filling of the carton. The plastic film is laminated onto the outside of the package and drawn into the hole. Thereby the plastic film seals the side walls of the laminate material.
  • the plastic film can also be used as a reclosing device, however, only with limited resealing function after initial opening. If this opening is provided as a two piece system, the plastic film also has to be disposed of, which in general is negatively registered by the user of such packaging containers.
  • DE 3513976 addresses the problem of an aperture in laminate material which has no exposed fibrous materials.
  • the disclosure suggests a multiple layered closure with several sealing points between the additionally introduced layers and the laminate adjacent to the aperture. The aperture itself is simply punched through the laminate.
  • DE 3808303 provides a reclosable opening device which is applicable to aseptic packaging and using the straw-hole technology to prevent humidity build-up in the fibrous structure of the laminate.
  • the opening device is provided as a single piece. However, a distance ring is removed from the opening device upon initial opening and remains permanently separated from the packaging. It thereby foresakes the advantage of being a single piece opening device and requires two distinctly different actions to open the container. Further, this design has the draw back that the construction height in its unopened state creates problems when packages are stacked onto each other.
  • EP-A- 167095 discloses a sealed gable top carton having a reclosable opening and pouring spout which is provided as a single piece.
  • the opening device is sealed to the sloped side of the gable top covering a cut away aperture in the carton laminate material. It thereby does not allow separate sterilizing treatment of the opening device and the laminate material. Also the danger of pocket building and security of reclosure is not properly addressed by this design.
  • the lid in order to provide sufficient stability against accidental opening, the lid must be strongly attached to the mouth piece. Therefore the initial opening will require substantial force which can lead to spilling and is not convenient for the end user.
  • EP-A-4332, EP-A-141229 and EP-A-214791 provide attempts at reclosable aseptic packaging by using adhesive tape, by inserting a corner of a flat top box into the opening as a reclosure or by a form fitting insertion of the laminate material cut out.
  • Document EP-A-0444862 discloses a reclosable opening member corresponding to the preamble of claim 1.
  • None of the aforementioned packaging containers provides all advantages desired by consumers of such packaging containers. As shown, the available packaging either lacks compatibility with modern aseptic packaging requirements, has no or only dissatisfactory pouring or even dripping, does not provide tight reclosing which would allow to shake the content of such a packaging container or leaves the user of such packaging with the requirement to dispose of a piece of material which has to be removed from the opening member upon initial use.
  • the opening member for a liquid packaging container made of laminate material such that the inside surface of the container can easily be sterilized by having an uninterrupted and pocket free layer forming the inside surface at least around the designated opening aperture.
  • the opening member should provide a drip free or drip reducing pouring spout, preferably one which directs fluid remaining on the spout back into the container when bringing the container into an upright position. Further, the opening member should provide convenient and easy handling when initially opening the container while preventing unintentional opening during transport and handling.
  • the opening member for a liquid packaging container has to be a single piece reclosable opening member which preferably can be opened in a single move and is capable of providing and maintaining an unobstructed and preferably hygienic opening over an extended period despite being exposed to liquid or humidity and without losing the laminate of the designated opening aperture into the container.
  • the invention relates to a single piece reclosable opening member and in another aspect to a liquid tight container comprising said reclosable opening member.
  • the containers are made of a laminate material and are typically gable top or flat top containers, preferably of a parallelepiped form.
  • the laminate material comprises two barrier layers on the outside and a structural stability layer between the barrier layers.
  • Most commonly these containers are used for non-carbonated beverage drinks like fruit juices, nectars, fruit juice drinks or milk. They contain usually a family size serving and are kept for some time after opening since they contain more than a single serving quantity. There is also a tendency to increase the container volume to save packaging material for environmental and economical reasons.
  • the opening member has a pouring aperture and is placed on the upper side of a container such that the pouring aperture corresponds to a designated opening aperture in the container.
  • the designated opening aperture is formed in the container laminate material by an endless weakening line around its circumference where the laminate material is designed to break upon initial opening of the container. This weakening line, regardless of how it is provided, is hereinafter termed designated breaking contour.
  • the designated breaking contour can have any shape which is desired and conforms to the circumference of the pouring aperture.
  • the designated breaking contour can be provided by partial cutting or by straw-hole technology.
  • the inside barrier layer forming the inside of the container should not be destroyed or punctured by the technology used for making the designated breaking contour.
  • the opening member comprises a flange forming a pouring aperture preferably also comprising a pouring spout to direct liquid and to reduce dripping when pouring and to drain liquids off the spout back into the pouring aperture.
  • the flange has a rim at its base extending outside the pouring aperture.
  • the opening member further comprises a lid for closing the pouring aperture which is hinged to the opening member, preferably to the rim.
  • the lid further comprises a plug which is permanently joined to the lid and has a bottom side. The bottom side extends from the lid into the pouring aperture when the lid is in a closed position such that the bottom side is in the same plane as the lower side of the rim. While the lid remains in its closed position the bottom side of the plug is movable into the pouring aperture.
  • the direction into the pouring aperture is opposite the flow direction through the pouring aperture.
  • This movability of the bottom side of the plug can be provided by elastic deformation of the plug or of the entire lid.
  • the plug and the lid are provided as separate elements which are joined to each other in the form of telescoping flanges that have interlocking opposing rims.
  • the lid of the opening member further comprises a lever which allows to push down the plug during initial opening in a single motion.
  • the lever has a first and a second end.
  • the second end of the lever forms the part of the lid which is opposite the side where the lid is hinged to the flange of the opening member.
  • the first end of the lever moves down in order to initiate movement of the plug into the pouring aperture.
  • the lever turns around an axis which preferably is defined by a crease in the lid. Except for the lever the lid remains in a closed position.
  • the present invention provides a reclosable liquid tight container having a designated opening aperture and comprising the opening member as described above.
  • the opening member is attached to the outside of the laminate material of the upper side of the container with its pouring aperture corresponding to the designated opening aperture such that the rim of the opening member is joined to the container along an endless liquid tight seal and the bottom of the plug is attached permanently to the laminate material inside the designated opening aperture.
  • the plug will push through the designated pouring aperture detaching a piece of laminate along the designated breaking contour while not losing the piece of laminate into the container.
  • the lid will lift the plug including the detached laminate from the designated opening aperture out of the pouring aperture and provide easy access to the content of the container. Reclosability is achieved by simple returning of the lid into its original position. The tightness of the reclosure can be improved if the plug either is conical or has a protruding bulge around the side of the plug. When closing the lid the conus or the protruding bulge engage with the inside of the flange of the opening member.
  • Figure 1 is a broken away perspective view of the laminate of a container adjacent the opening aperture in combination with a preferred embodiment of the opening member of the present invention.
  • Figure 2 is a cross-sectional view of the opening member and laminate material along line 2-2 of Figure 1 in its initial closed position.
  • Figure 3 is the same cross-sectional view as Figure 2 after the initial motion of the lever of the preferred embodiment of the opening member.
  • Figure 4 is the same cross-sectional as Figure 3 after the second part of the opening motion when the lid has lifted off the opening member.
  • Figures 5 and 6 are cross-sectional views of an alternative embodiment of the opening member according to the present invention, the opening member having a lever and an external turning axis in the closed position and after the initial motion of the lever, respectively.
  • Figure 7 is a cross-sectional view of another alternative embodiment of the opening member according to the present invention, not having a lever but having a flexibly movable plug.
  • Figure 8 is a cross-sectional view of a designated breaking contour made by straw-hole technology.
  • Figure 9 is a cross-sectional view of the designated breaking contour made by partial cut technology.

  • Figure 2, 3 and 4 show a schematic cross-sectional view of the preferred embodiment of the opening member of Figure 1 along line 2-2 at different operating situations.
  • the opening member is closed
  • Figure 3 shows the opening member after the first part of the initial opening motion
  • Figure 4 shows the opening member in its fully opened motion.
  • the opening member (10) comprises a flange (12) which forms a pouring aperture (14) and has a rim (16).
  • the rim (16) has a lower side (116) and extends outside the pouring aperture (14) from the flange (12).
  • the rim as shown has a rectangular shape with rounded edges, however other shapes for the rim (16) like an oval shape or a shape following the outline of the flange (12) can also be used.
  • the lower side (116) of the rim (16) provides the contact area for joining the opening member (10) to the laminate (30) forming the upper side of a container.
  • the preferred embodiment of the opening member (10) as shown has a lid (18) which is hinged to the rim (16).
  • the lid (18) could also be hinged to other parts of the opening member (10) for example the lid (18)could be directly hinged to the flange (12).
  • the lid (18) in its closed position the lid (18) as shown in Figure 1 and 2 closes the pouring aperture (14).
  • the lid (18) comprises a plug (50) which extends into the pouring aperture when the lid (18) is closed as shown in Figure 2.
  • the plug (50) has a bottom side (52) which is spaced from the lid such that it forms a single plane with the lower side (116) of the rim (16) when the lid (18) is closed.
  • the plug (50) is permanently joined to the lid (18).
  • the plug (50) is joined to the lid (18) by a telescoping flange (54) of the plug (50) having an inwardly extending rim (56) at the end of the flange (54) opposite the bottom side (52) of the plug (50).
  • the lid comprises also a flange (19) which is reaching into the tubus formed by the flange (54) of the plug (50) having an external rim (21) which provides together with the inwardly extending rim (56) a permanent but movable securement between the plug (50) and the lid (18).
  • the lid (18) provides the opening member (10) with reclosability.
  • the tightness of the closure of the lid (18) can be further improved by having the plug (50) extend tightly into the pouring aperture (14) when the lid (18) is in its reclosed position.
  • a protruding bulge on the outside of the flange (54) of the plug (50) or a conical shape of the flange (54) is also included.
  • the opening member (10) preferably also has a pouring spout (24)
  • the pouring spout (24) is preferably at the opposite end of the pouring aperture (14) from where the lid (18) is hinged to the opening member (10).
  • pouring spouts (24) which provide not only direction to liquids coming from the pouring aperture (14) for pouring but which extend beyond the outer perimeter of the rim (16) to guide liquids clear of the rim (16).
  • pouring spouts (24) which are also angled such that liquid which remains on the pouring spout (24) is drained back through the pouring aperture (14).
  • the lid (18) of the opening member (10) further comprises a lever (20).
  • the lever (20) has a first end (23) and a second end (25) and a turning axis (26).
  • the lever is an integral piece of the lid (18) of the opening member (10) having a manipulating aperture at the second end (25) of the lever (20).
  • the second end (25) forming the front end of the lid (18) is lifted and turned around the axis (26) thereby moving the first end (23) downwards and pressing the plug (50) below the plane of the lower side (116) of the rim (16).
  • the axis (26) of the lever is formed in the lid (18) of the opening member (10) preferably by a crease in the lid material.
  • any other useful hinged attachment of the lever along the axis (26) known in the art can be employed.
  • the lid (18) between the axis (26) and that end of the lid which is hinged to the opening member must be held in its closed position .
  • This can be accomplished for example by external material bridges (27) attaching the lid (18) to the rim (16) of the opening member (10).
  • These material bridges (27) additionally provide indication of pilfering or tampering with the opening member.
  • the lid (18) between the axis (26) and its hinged end can be held in place by internal material bridges or by any other temporary mechanical restraints like for example a snap lock.
  • An example of a snap lock which is used to hold the second end (25) of the lever (20) down by engaging with the pouring spout (24) is shown in Figure 2. Regardless of how the lid (18) is held in place it must allow in the second part of the opening motion to lift the lid (18) easily off the pouring aperture (14).
  • FIG. 5 shows an alternative embodiment of the opening member (10).
  • This single piece opening member (10) utilizes the flexibility of plastic materials to deform without breaking. It comprises principally the same elements as the previously described opening member, however the axis (26) of the lever (20) in this embodiment has moved forward away from the hinge between the lid (18) and the opening member (10).
  • the plug is extending as an integral piece of the lid downward into the pouring aperture (14) without having a telescoping flange attachment.
  • Figure 6 shows this alternative embodiment of the opening member (10) after the lever (20) has been lifted at its second end (25) and the plug (50) has moved downwards.
  • the plug (50) is formed as a tubular depression in the lid (18).
  • Figure 7 shows another alternative embodiment of the present invention not using a lever.
  • the user of the opening member (10) needs to press the plug (50) manually downward in order to provide the required downward motion of the plug and then lift the lid (18) to open the pouring aperture (14).
  • This embodiment of the opening member (10) is however less preferred than the previously described embodiments of the opening member (10) since it requires two separate steps for the user of the opening member.
  • the opening member is made of plastic material.
  • it is made of polyethylene, polypropylene, polystyrol or mixtures thereof. It can be produced by any manufacturing technique usually used in the art.
  • it is made by injection molding as a single piece, or in case of the preferred embodiment of Figures 1-4 as two pieces which are permanently joined to form a single piece opening member.
  • the plug material preferably exhibits an elastic flexibility to allow and accomodate turning and bending which is required for the snap lock at the pouring spout (24), the hinge of the lid (18) or the turning (26) of the lever (20) around the axis (26).
  • the present invention provides a reclosable liquid tight container comprising an opening member as described above.
  • the liquid tight containers of the present invention are made of laminate material.
  • the laminate material comprises two barrier layers and a structural stability layer sandwiched between the barrier layers.
  • the barrier layer forming the outside surface of the container, has the function of providing protection of the container against humidity and contamination from the container's environment. It preferably consists of one or several plies of plastic film, for example polyethylene, providing a liquid barrier and being weldable and compatible with many adhesives, particularly hotmelt adhesives.
  • the barrier layer forming the inside surface of the container has the function of protecting and containing the liquid inside the container as well as protecting the structural stability layer from exposure to the liquid contents of the container.
  • it also comprises one or several plies of plastic film, for example polyethylene.
  • it may comprise a ply of gas tight material for example an aluminum foil which prevents in particular oxygen migrating into the container.
  • the structural stability layer is sandwiched between the barrier layers together with any other additional layers which may be desired.
  • the structural stability layer provides the laminate with the structural stability allowing to form self supporting containers with it.
  • Most commonly used materials for the structural stability layer are paper or cardboard plys which themselves may be sandwiched together forming the structural stability layer.
  • the laminate is formed in lamination processes well known in the art. Typically the two barrier layers and the structural stability layer are sandwiched together while applying high pressure and heat thereby forming an intimate bond between the layer interfaces. Bonding materials, if used at all, can be selected from a wide range of pressure sensitive, heat sensitive, hot melt type adhesives and other bonding agents.
  • the stability of the structural stability layer against internal delamination is usually small. Particularly when the structural stability layer is made of fibrous material like paper or cardboard, the opening tensile force perpendicular to the plane of the structural stability layer would delaminate this layer. Therefore it is not possible without special arrangements to prevent internal delamination of the structural stability layer if a pull-out opening in the laminate material is desired.
  • an area without the structural stability layer in order to create a designated opening aperture in the laminate material is also technically unattractive since it creates a weak area in the overall laminate material thereby requiring special handling when producing, sterilizing and handling a container.
  • the container is made of laminate material. It preferably is made out of a single piece of laminate material which is cut and folded together so as to form either a gable top container or preferably a container resembling a parallelepiped.
  • the important characteristic of the container is that it provides secure and hygienic containment for liquid products like non carbonated beverages.
  • the container has an upper side which in the case of a gable top container is tilted and in case of a parallelepiped is a flat horizontal surface.
  • this upper side comprises an opening member as described above.
  • the opening member (10) is permanently joined to the outside of the laminate of the upperside of the container by an endless, liquid tight seal around the rim (16).
  • the plug (50) is also permanently joined to the laminate, preferably the seal extends to the bottom side (52) of the plug (50) however, without the requirement to be liquid tight.
  • the rim (16) and the plug (50) can be joined to the laminate by any known technique but preferably use hot melt adhesive, welding or ultrasonic bonding.
  • the upper side of the container comprises a designated opening aperture (38) which is located in the laminate material.
  • the designated opening aperture is defined by an endless container which is designated to break upon initial opening of the contour.
  • the designated breaking contour is formed by weakening the laminate material without destroying or puncturing the barrier layer forming the inside of the container along the designated breaking contour.
  • the designated breaking contour as indicated in Figure 8 can be formed by straw-hole technology, that is by removing the structural stability layer (36) and laminating the two barrier layers (32,34) to each other through the removed structural stability layer (36). Small material bridges holding the structural stability layer inside the designated breaking contour in place until lamination of the barrier layers (32,34), represent no deviation from the principally preferred straw-hole technology for its hygienic appearance.
  • the designated breaking contour can also be formed as indicated in Figure 9 by partial cut technology. Partial cut technology provides cuts into the laminate (30) which do not extend through the full thickness of the laminate (30) and therefore maintain the integrity of the inner barrier layer (34).
  • the shape of the pouring aperture (14) and the designated opening aperture (38) is not limited to the shape shown in the drawings. Both apertures independently can be selected from round, oval, rectangular and triangular shapes or any other desired shape useful in providing the desired function in particular including conically extending oval shapes.
  • the opening aperture (38) has the same or a similar shape and size as the pouring aperture (14) of the opening member (10).
  • the opening member (10) is disposed on the laminate material (30) such that the pouring aperture (14) of opening member (10) corresponds to the opening aperture (38) in the laminate material (30).
  • a container according to the invention comprises the opening aperture (38) preferably at the edge of its upper side so that the pouring spout (24) reaches all the way to or even beyond the edge of the upper side of such a container.
  • the lid (18) is closed thereby also protecting the pouring aperture (14) and the pouring spout (24) for hygienic reasons.
