Definitions

  • the disclosure pertains to a sealing disc for sealing an inner compartment in a packaging container.
  • the sealing disc is a two-layer structure comprising a top member and a bottom member which are joined in a border seal along the peripheral edges of the top and bottom members.
  • the sealing disc is provided with a tear-away area which is delimited by a contour line arranged in the top member.
  • a tear strip is arranged in the top member.
  • the tear-strip is a part of the tear-away area and comprises a pull-tab which is arranged at a grip end of the tear strip.
  • the tear strip and the contour line are defined by cut lines in the top member, the cut lines comprising first cut line and a second cut line.
  • Disclosed herein is also a packaging container comprising the sealing disc.
  • Consumer goods in particular bulk solids, are often packaged in relatively rigid paperboard packaging containers which protect the bulk solids during transport and storage at the manufacturer and retailer end and during storage and dispensing at the consumer end.
  • One of the important factors in the area of bulk packaging containers is to ascertain that the quality of the packaged goods remains at a high level from the initial opening of the container until the packaged product has been completely consumed.
  • the containers are usually provided with an openable and closable lid, and are additionally provided with inner transport seal which keeps the contents fresh and protected against contamination up until a first opening of the packaging container by a consumer.
  • a common type of transport seal is a sealing disc comprising a top member and a bottom member. The top member is provided with cuts, forming a tear strip and a tear-away area which includes the tear strip.
  • the tear-away area is delimited by a contour cut which forms an outer tear line extending in the top member along the full contour of the tear-away area.
  • the tear-strip is formed by a different cut arranged inward of the contour cut in the top member.
  • the top member and the bottom member are selectively interconnected in a peripheral border seal and at one or more locations within the tear strip and usually also within a further location in the tear-away area, outside of the tear strip.
  • Document JP S61 217350 A relates to a sealing lid of a container, which comprises a tear opening and discloses a sealing disc according to the preamble of claim 1 and a method according to the preamble of claim 14.
  • Document US 4 556 152 A relates to tear opening means for containers, especially powder proof, liquid proof or gas proof containers of the type which at least at one end is closed by means of an end closure providing an openable end panel, which for instance over a sealing edge sealingly engages the container sleeve, and, in which, the end closure is punched through along a line of the end panel extending some distance inside of the sealing edge.
  • the end panel carries a sealing foil of a weldable or solderable material which is welded or soldered to the end panel so as to seal the through punching of the end panel.
  • the end panel is made of a material having higher shearing strength than that of the material of the lower sealing foil, so that the container can be opened along a sharp line corresponding to the through punching of the end panel.
  • the end panel may be formed with a tearing tongue or any other means, by which the container can be opened.
  • a packaging for pulverulent material consisting of a container part, made up of a laminate consisting of paper (board), metal foil and plastic material.
  • the powder is filled into such a container and a seal consisting of a plastic film that is fixed to the container wall by heat sealing is applied on top of the powder.
  • a small gap remains between the film and the lid to be placed on the container (in the closed state).
  • a scoop is fitted in this gap. After first use, the scoop is snapped into a fixing in the lid.
  • the lid is provided with an elevation for accommodating the scoop in the lid.
  • An object of the present disclosure is to provide a sealing disc having a more reliable opening arrangement. Further objects of the present disclosure are to offer a method for producing an improved sealing disc, as well as a packaging container being provided with an improved sealing disc.
  • the sealing disc for sealing an inner compartment in a packaging container as disclosed herein comprises a top member and a bottom member.
  • the top member has a top member peripheral edge and the bottom member has a bottom member peripheral edge.
  • the top member is joined to the bottom member in a border seal arranged along the top member peripheral edge and the bottom member peripheral edge at the contour line.
  • the sealing disc comprises a tear-away area, which is delimited by a contour line arranged in the top member, and a tear strip being arranged in the top member and being part of the tear-away area.
  • the tear-strip comprises a pull-tab which is arranged at a grip end of the tear strip.
  • the top member comprises a first cut line and a second cut line, wherein the first cut line has a first end and a second end arranged on the contour line and constitutes a first portion of the contour line extending between the first end and the second end of the first cut line.
  • the second cut line has a first end and a second end, the first end being arranged on the contour line, and the second end of the second cut line being arranged within the tear-away area.
  • the second cut line comprises a tear strip section and a contour section, the tear strip section delimiting the pull-tab and an inner edge of the tear strip and the contour section constituting a second portion of the contour line and, at the same time, an outer edge of the tear strip.
  • the first end of the first cut line adjoins the second cut line at a transition portion between the tear strip section and the contour section of the second cut line and is arranged at a distance from the transition portion between the tear strip section and the contour section of the second cut line.
  • the sealing disc has a modified rectangular shape with four side edges joined by four curved corner portions and the transition portion between the tear strip section and the contour section of the second cut line is arranged at one of the curved corner portions.
  • a second cut line which is separated from the first cut line, which second cut line forms the tear-strip with the pull tab as well as a portion of the contour line of the tear-away area of the sealing disc has proven to considerably reduce tear-strip failure.
  • pulling at the tear-strip may be made without the pulling force having to be transferred between different cuts or abruptly change direction at an area where there is an angle between the cuts, i.e. where the pull-tab joins the contour line of the tear-away area.
  • the tear-strip as disclosed herein can be used to tear open the sealing disc in a smooth and controlled and continuous tearing movement starting at the pull-tab part of the tear-strip which is located in the tear-away area of the sealing disc, continuing over the transition between the tear strip section and the contour section of the second cut line into the contour section of the second cut line.
  • the contour section of the second cut line also constitutes the outer edge of the tear strip, the tear strip being defined between the contour section of the second cut line and the tear strip section of the second cut line.
  • the first and the second cut lines may be formed as continuous cuts, or may be formed as intermittent cuts with one or more un-cut tabs between cut sections which uncut tabs may have a length of at most 2 millimetres, preferably at most 1 millimetre.
  • the distance between the first end of the first cut line and the transition portion between the tear strip section and the contour section of the second cut line may be in the range of from 0.5 millimetres to 5 millimetres, such as from 0.9 millimetres to 2 millimetres.
  • the area where the pull-tab part of the tear strip joins the contour line which delimits the tear-away area has proven to be the most sensitive part of a tear-open arrangement for a sealing disc.
  • the contour line is formed by an outer cut extending in the top member along the full contour of the tear-away area.
  • the tear-strip with the pull-tab is formed by an inner cut arranged in the top member. It has been found difficult to correctly synchronize the inner cut with the outer cut. If the inner cut does not reach all the way to the outer cut, poor tearing of the tear-strip or even tear strip failure has been known to occur.
  • a construction of this kind has also proven to be very sensitive to different tear behaviour of different users.
  • some users tend to pull the tear strip in a direction towards the outer cut or contour line and may end up tearing across the outer cut, into the border seal which in the worst case results in complete tear-strip failure and in the best case results in poor tearing with rugged tear edges or only partial removal of the tear-away area.
  • the sealing disc as disclosed herein has a modified rectangular shape with four side edges joined by four curved corner portions.
  • Modified rectangular shapes include modified square shapes, i.e. rectangular shapes having side edges of equal length.
  • the side edges of a sealing disc having rectangular or modified rectangular shape may consist of first and second longitudinal side edges and first and second transverse side edges, the longitudinal side edges having a length greater than a length of the transverse side edges.
  • the side edges may be straight side edges or may have a slight curvature, with a radius of curvature in the range of from 200-700 mm, preferably 300-600 mm, more preferably 400-500 mm.
  • the side edges are connected by curved corner portions, wherein the radius of curvature of the corner portions may be in the range of 5-60 mm, preferably 10-40 mm, more preferably 15-30 mm.
  • the transition portion between the tear strip section and the contour section of the second cut line may be arranged at a curved corner portion, such as at one of the curved corner portions in a sealing disc having a modified rectangular shape.
  • Arranging the transition portion between the tear strip section and the contour section in a curved corner portion has been found beneficial for prompting users to grip and pull the tear-strip in a correct way, thereby further promoting controlled tearing and minimizing tear-strip failure.
  • a modified rectangular sealing disc having two longitudinal side edges and two transverse side edges, it has been found to be particularly beneficial to arrange the second cut line with the contour section of the second cut line extending along one of the first and second longitudinal side edges.
  • the pull-tab end of the tear-strip will be arranged at one of the transverse side edges, i.e. along one of the short side edges.
  • Such arrangement has been found to even further promote consistency in the tearing pattern between different users by inducing pulling of the tear strip in a correct tearing direction.
  • first portion of the contour line and the second portion of the contour line together form the contour line delimiting the tear-away area. Accordingly, no further cuts are involved in forming the contour line.
  • first and second ends of the cut line are aligned with each other or generally aligned with each other, such that tearing along the contour line may be performed continuously from the second cut line over to the first cut line.
  • the adjoining ends of the first and second cut lines are preferably arranged at a small distance from each other along the contour line, leaving a non-cut tab between the adjoining ends of the first and second cut lines in the upper member. Such tab has no or practically no negative influence on the tearability of the sealing member, but aids in stabilizing the upper member during production and may provide for production tolerances when applying the first and second cut lines to the top member.
  • the distance between the adjoining ends of the first and second cut lines i.e. the width of the non-cut tab between the adjoining ends of the first and second cut lines is preferably small, such that the second end of the first cut line adjoins the first end of the second cut line at a distance between the second end of the first cut line and the first end of the second cut line being in the range of from 0.3 millimetres to 2 millimetres, such as from 0.7 millimetres to 1.2 millimetres and preferably 1 millimetre or less.
  • the second end of the first cut line may adjoin the first end of the second cut line at a curved corner portion of the sealing disc or at a transverse side edge.
  • the transition portion between the tear strip section and the contour section of the second cut line may be curved and may have a radius of curvature in the range of from 15 millimetres to 22 millimetres, such as from 17 millimetres to 20 millimetres.
  • the radius of curvature of the transition portion between the tear strip section and the contour section of the second cut line may be smaller than the radius of curvature of the curved corner portions which, in such case, may be in the order of from 20 millimetres to 60 millimetres, such as from 20 millimetres to 40 millimetres.
  • the tear strip may have a width in the range of from 15 millimetres to 30 millimetres, such as from 18 millimetres to 25 millimetres.
  • the width of the tear strip is the distance between the outer edge of the tear strip defined between the contour section of the second cut line, and the inner edge of the tear strip.
  • the width of the tear strip is measured in a portion of the tear strip which is not the pull tab and may be constant along the length of the tear strip or may vary along the length of the tear strip.
  • the pull-tab part of the tear strip may have a width which is different from the width of other parts of the tear strip, such as a larger width to provide an enlarged grippable portion at the pull-tab end of the tear strip.
  • top member to the bottom member is preferably made by heat sealing, although adhesive attachments may be used as an alternative or as a complement.
  • the top member and the bottom member are preferably laminates comprising a thermoplastic bondable layer and a structural layer, such as a layer of aluminium foil, paper, etc.
  • the attachments between the top member and the bottom member are permanent attachments, implying that the material in the layers will break before an attachment is broken when pulling at the tear strip.
  • the border seal is preferably a continuous seal such as a continuous weld seal which extends around the full periphery of the sealing disc.
