Definitions

  • the invention pertains to a stack of interfolded tissue-sheets packed in a container, said container having a generally planar bottom wall and a top wall and side walls connecting the bottom wall with the top wall and an opening provided in at least one wall for the removal of said tissue-sheets from the container, said stack of interfolded tissue-sheets being placed in said container with at least the edges of a lowermost tissue-sheet placed on the bottom wall and an uppermost tissue-sheet placed near or in contact with the top wall and adjacent to the opening in the top wall.
  • Soft tissue sheets such as facial tissue sheets are commonly offered as a stack of tissue sheets packed in a dispensing box.
  • the dispensing box has an opening through which the user pulls the tissue sheets.
  • the tissue sheets are interfolded, which means that the tissue sheets are folded into one-another, so that they form a chain of tissue sheets being interconnected by folded portions.
  • the pulled-out tissue sheet will automatically bring a portion of the next tissue sheet in the stack out through the opening thereby making it readily available for gripping and removing from the dispensing box.
  • interfolding tissue sheets in this manner is a convenient way of ascertaining that all of the tissue sheets can be easily removed from the container.
  • interfolding e.g. Z-folding
  • the type of interfolding nor the type of tissue is important to the invention.
  • a dispenser of this type is known from US-A-6,053,357 (YOH), which discloses a box with a dispensing opening having a curvilinear or "S"-shape.
  • the opening facilitates the dispensing of interfolded tissues from a box by fixing the top sheet in a position extending out through the opening, where it is readily accessible to a user.
  • the box requires a dispensing means that enables a tissue to be gripped and held securely in a presentation position, while allowing it to be pulled freely from the box by the user.
  • the present invention offers a simple and expedient means of solving the problem of dispensing a flat tissue sheet from a stack of interfolded tissue sheets which are packed in a container having a dispensing opening.
  • the opening is wider than the width of said tissue sheets.
  • the invention will, however, also be applicable for openings of equal or narrower width than the width of the tissue sheets.
  • the dispensing opening is provided with means for presenting a tissue blocked in a fixed position, with a flat configuration. This allows the user to pull the presented tissue out flat, whereby potential wrinkling is smoothened out by the presenting means.
  • the presented tissue may be a single sheet, or may itself have additional folding.
  • the means for presenting the tissue is preferably in the form of a number of elongated projections or fingers extending from opposite sides of the dispensing opening of the box.
  • the dispensing opening is preferably, but not necessarily, located in the top wall of the box.
  • the fingers are overlapping by extending between each other in the plane of the top wall.
  • the fingers may be attached to the underside of the top wall of the box, on opposite sides of the opening. It is also possible to attach the means including said fingers on the upper side of the top wall of the box, or to integrate it into the top wall itself, e.g.
  • the fingers By making the fingers part of the top wall. When the first tissue is being pulled out through the opening, the fingers will be pulled upwards by the tissue on either side thereof. The pulled-out tissue will automatically bring a portion of the next tissue out through the opening, where it will pass between the fingers. As the first tissue is removed, the subsequent tissue will be held in position and prevented from falling back into the box by the gripping action of the opposing fingers.
  • the fingers must be sufficiently flexible to allow a tissue to be pulled out, while at the same time being sufficiently stiff to retain the tissue and prevent it from falling back. Accordingly, the thickness and stiffness of a plastic film, or other suitable material, used for the fingers must be selected to match the stiffness and material properties of the tissue.
  • overlap in the context of pairs of interacting projections, is used to denote that the tips of a pair of adjacent projections, which are not necessarily in contact, extend past each other, as seen in a plan view. This is the case when the fingers are in their initial positions, before the first tissue has been dispensed. Once a tissue has been withdrawn, the opposing fingers are placed on opposite sides of the subsequent tissue to present it to the user. The fingers are then bent or flexed away from the top wall, to assume a dispensing position in the form of a mainly curved shape. An opposing pair of fingers, or the tips thereof, on either side of a tissue will be in point or line contact with said tissue, thus creating sufficient friction to prevent the tissue from falling back into the box.
  • the shape of the fingers is important in order to retain a gripping position. Particularly, the tips of a pair of opposing fingers should be relatively large or "fat" to provide said point or line contact with a tissue.
  • At least one pair of opposing projections is provided with at least one outer section with a surface area that is larger than the surface area of a corresponding length of an inner section.
  • Said first and second sections may or may not partially overlap.
  • the area of the outer section extending past a central longitudinal axis of the opening is larger than the surface area of the inner section from said axis to a base of the projection.
  • each projection of at least one pair of opposing and co-operating projections has at least one inner section having a smaller width than an adjacent outer section.
  • the widths can be measured at any point on the main axis of said projection.
  • said width of the respective inner and outer sections is the cross-sectional width in the perpendicular direction of either the main axis of said projection or the main, longitudinal axis of said opening.
  • the radius of a projection at the point of contact with an opposing projection, in the dispensing position is greater than half the width of the projection at its narrowest section.
  • the opening in the top wall comprises a shaped slot provided with said projections.
  • said slot can have at least one cut-out section for allowing access to said uppermost tissue-sheet. Said cut-out section may be removed during the manufacture of the box, or during opening of the box to allow access to the tissues.
  • the main, longitudinal axis of the opening containing said slot extends across the top wall along or parallel to a longitudinal axis of the top wall.
  • the opening may thus be positioned along the centreline of the box, or on either side thereof.
  • the main axis of the opening containing said slot extends across the top wall at an angle relative to the longitudinal axis of the top wall.
  • the angle can be given any value on either side of said longitudinal axis up to and including an angle corresponding to the angle of a diagonal line between opposing corners of the top wall.
  • the main axis of the opening containing said slot extends across the top wall in a generally S-shaped curve extending in the general direction of a line connecting the ends of the opening
  • the shape of the edges of the opening can follow the shape or curvature of the main axis of the opening, but can also follow a curved or broken line in the general direction of said axis.
  • the width of the opening is greater or greatest near the middle of the top wall, while its narrowest section is at or near the end sections of the top wall.
  • the end sections of the opening may end in a straight line at the respective edges of the top wall. However they may also end with a rounded section, either near the edges of the top wall or extending a small distance down the respective end walls of the box.
  • said slot is an insert attached to the top wall, which insert covers the opening.
  • the insert may be made from a plastic material, such as polypropylene, in order to give both sufficient flexibility and stiffness. The flexibility and stiffness may also be varied by using plastic materials of different thickness.
  • the opening can be used to control the flexibility and stiffness of the fingers arranging the edge of the opening at a predetermined distance from said fingers.
  • a wide opening positioned away from the base of the fingers will give high flexibility and low stiffness.
  • an opening having an edge overlapping the recesses of opposing fingers will give low flexibility and high stiffness. In this way the fingers may be adapted for tissues of different materials and materials of different thickness.
  • said slot is arranged in the top wall, which then makes up the opening.
  • the box itself is made from a plastic material, having projections or fingers cut or perforated in the top wall.
  • the opening which would normally control the movement of the fingers, can be embossed directly on the top wall. It is also possible to provide each individual finger with a specific embossing or pattern, in order to give each finger a predetermined flexibility.
  • the shape of the slot containing the projections or fingers or the positioning and shape of the embossed opening can be the same as described in connections with the embodiments above.
  • any two consecutive pairs of opposing fingers should co-operate independently.
  • a cut line between adjacent fingers of two pairs of opposing fingers should only have one inflection point. In the vicinity of the inflection point, the cut line should be straight or have a comparatively large curvature. In this way it is ensured that each pair of opposing fingers can move and flex together without interference from adjacent pairs of fingers.
  • Figures 1A-F show a plan view of a top wall 1 of a box including a pair of folded out end walls 2, 3.
  • the box also includes two side walls, which together with the end walls connect the top wall with a bottom wall (not shown).
  • the box encloses a stack of interfolded tissues to be dispensed through an opening.
  • the following examples describe the opening arranged in the top wall, but it can of course be arranged in any of the said walls. Obviously, the stack of folded tissues would need to be adapted accordingly.
  • FIG. 1A illustrates a number of different configurations for a dispensing opening 4 in the top wall 1.
  • the edges 5, 6 of the opening are arranged symmetrically on either side of a central longitudinal axis A X of the box, thus coinciding with the main axis of the opening 4.
  • the opening 4 has its minimum width W 1 in the top wall at a folding line 7, 8 between the top wall 1 and each respective end wall 2, 3.
  • the maximum width W 2 of the opening 4 is placed at a central transverse axis A Y of the box.
  • each edge 5, 6 is made up of straight lines 9, 10, 11,12 from a point 13, 14, 15, 16 where the edge intersects said folding line 7, 8 to a point 17, 18 where the edge 5, 6 intersects the transverse axis A Y and the opening 4 reaches its maximum width W 2 .
  • the opening 4 extends past the folding line 7, 8 a short distance X into the respective end wall 2, 3.
  • the opening 4 is terminated by a rounded edge 19, 20, having a substantially semicircular shape.
  • the invention is, however not limited to this shape.
  • Figure 1A shows an opening wherein the straight lines continue a short distance into the end walls before being terminated. It is, however, also possible to place the rounded edge on or immediately after the folding edge, or to terminate the opening along the folding line (see Fig. 1B). If a stack of tissues (not shown) does not take up the entire space between the end walls, it is also possible to terminate the opening before it reaches the folding lines.

  • the edge 5, 6 can make either a smooth or a sharp transition at the intersection point P 1 .
  • This embodiment also shows an opening 4 having both its ends terminated along the folding lines 7, 8.
  • Figure 1D shows an opening 4 having a fourth alternative shape.
  • the main axis A M of the opening 4 is placed at an angle ⁇ relative to the longitudinal axis A X of the box.
  • the main axis A M has thereby been rotated around the point P XY of intersection between the longitudinal and transverse axes A X and A Y .

  • a central cut-out portion 102 is arranged between two inner pairs of fingers 94, 95; 96, 97 placed on either side of the central transverse axis A Y
  • Two further, outer cut-out portions 103, 104 are arranged at either end of the opening 4.
  • the main axes A 1 -A 6 of the fingers are all placed at substantially the same angle a in relation to the longitudinal axis A X .
  • the fingers are arranged symmetrically around the central transverse axis A Y only.
  • the main axes of each of the corresponding fingers on either side of the transverse axis A Y will intersect on that axis A Y .
  • the innermost fingers 94, 96 will diverge from each other on either side of the transverse axis A Y , but on the same side of the longitudinal axis A X .
  • This arrangement allows a larger central cut-out 102, which makes the upper tissue more accessible to the user when the first tissue is to be pulled out.
  • the diverging innermost fingers 94, 96 will to a certain extent stretch and smoothen the central part of a tissue held in the presentation position.
  • Figure 8 shows an alternative embodiment of the arrangement in Figure 7, using a top wall with an opening as described in connection with Figure 1C.
  • adjusting the transverse width W 1 , W 2 of the opening makes it possible to adapt the stiffness and/or flexibility of the fingers to different types of tissues.
  • Figure 9 shows a plan view of a top wall 1 provided with an opening 4 as defined in relation to Figure 1B.
  • the shape has been modified in order to allow the tips to be enlarged further.
  • the embodiment shown in Figure 9 is provided with fingers wherein the centreline C F for the cut line of the slot is a straight line coinciding with both the main axis A M of the opening 4 and the central longitudinal axis A X of the top wall 1.
  • the fingers 110, 111; 112, 113; 114, 115; 116, 117; 118, 119; 120, 121 have their main axes A1-A12 placed at substantially the same angle ⁇ relative to the longitudinal axis A X .
  • the minimum width W Min at right angles to the main axis of each finger occurs in an inner section.
  • the maximum width W Max at right angles to the main axis of each finger occurs in an outer section.
  • the minimum width W Min and the maximum width W Max occur on opposite sides of the main axis A M of the opening.
  • the maximum width W Max is in excess of twice the minimum width W Min .
  • the outer section having an increased width allows a larger radius R T for the tip of each finger, which radius R T is greater than the minimum width W Min .
  • the area of the outer section is encompassed by the edge of an outer part of a finger, including the tip, delimited by the centreline of the opening.
  • the area of the inner section is encompassed by a pair of edges on either side of an inner part of a finger, delimited by the centreline of the opening on one side and a line drawn at a tangent to, and extrapolated past the tips of all adjacent fingers on the respective sides of the opening. The latter line is the base of the finger.
  • the maximum and minimum widths of each finger can be varied to achieve a desired tip radius.
  • the widths must be in proportion to the extended length and required stiffness of a finger.
  • the length of a finger is dependent on the transverse width of the opening in the region of the finger.
  • there will be a lower limit for the minimum width W Min In order to maintain a certain stiffness and flexibility for a finger having a predetermined length, there will be a lower limit for the minimum width W Min . This will determine an upper limit for the maximum width W Max , which in turn decides the largest possible tip radius R T .
  • a central cut-out portion 123 is arranged between two inner pairs of fingers 114, 115; 116, 117 placed on either side of the transverse axis A Y of the top wall 1. Both the innermost fingers 115, 116, adjacent the central cut-out, are arranged in substantially opposite directions, with their parallel axes A 1 diverging from the point P 0 of intersection of said longitudinal and transverse axes A X , A Y . Two further, outer cut-out portions 123, 124 are arranged at either end of the opening 4.
  • Each outer cut-out 123, 124 is placed between and extending into, the end wall 2, 3 of the box and an outer pair of fingers 110, 111; 120, 121.
  • Figure 10 shows a plan view of a top wall 1 provided with an opening 4 as defined in relation to Figure 1A.
  • This figure shows a third embodiment of the fingers, which have been given a shape that allows a relatively large tip radius without enlarging the surface area of an outer section of the finger.
  • the opening 4 in this embodiment is provided with fingers having a centreline C F for the cut line of the slot is a straight line coinciding with both the main axis A M of the opening 4 and the central longitudinal axis A X of the top wall 1.
  • the fingers 130, 131; 132, 133; 134, 135; 136, 137; 138, 139; 140, 141 have their main axes A 1 -A 6 placed at substantially the same angle a relative to the longitudinal axis A X .
  • each of the tips of a pair of adjacent, opposing fingers have been angled towards each other. This has been achieved by curving or bending the cut line of the outer section of each tip of a co-operating pair of fingers towards the inner section, or base, of a corresponding opposing finger.
  • Each such finger has a general J- or L-shape, depending on the curvature or the angle of the tip.
  • R T By extending the curved or bent section of the tip in the longitudinal direction of the opening 4, it is possible to achieve a larger tip radius R T .
  • the cut line between each pair of fingers will only have one inflection point, in order to avoid interference between adjacent pairs of fingers. In their plane, initial position the tips of each pair of fingers will be curved or bent into a corresponding recess in the other in an interlocking position.
  • the width of the tip is limited by the required stiffness and flexibility of the adjacent finger at that point.
  • the maximum width W Max of the outer section, or tip, of a particular finger is substantially equal to the corresponding inner section at the base of said finger.
  • the minimum width W Min will instead occur near the inner corner of the J- or L-shaped finger, in the vicinity of the tip. Hence both the maximum and minimum widths occur on the same side of the central longitudinal axis A X .
  • a central cut-out portion 143 is arranged between two inner pairs of fingers 134, 135; 136, 137 placed on either side of the transverse axis A Y of the top wall 1. Both the innermost fingers 135, 136, adjacent the central cut-out, are arranged in substantially opposite directions, with their parallel axes A 1 diverging from the point P 0 of intersection of said longitudinal and transverse axes A X , A Y . Two further, outer cut-out portions 143, 144 are arranged at either end of the opening 4. Each outer cut-out 143, 144 is placed between and extending into, the end wall 2, 3 of the box and an outer pair of fingers 130, 131; 130, 131.
  • fingers having tips with a general J- or L-shape are of course possible.
  • One such alternative tip could for instance have a T-shape.
  • a cut line for the slot making up the fingers could also contain a number of pairs of fingers, wherein each pair could have differently shaped fingers
  • Figure 11 shows a plan view of a top wall 1 provided with an opening 4 as defined in relation to Figure 1A.
  • the embodiment shown in Figure 11 is provided with fingers wherein the centreline C F for the cut line of the slot is a straight line coinciding with both the main axis A M of the opening 4 and the central longitudinal axis A X of the top wall 1.
  • the shape of the fingers 150, 151; 152, 153; 154, 155; 156, 157; 158, 159; 160, 161 has been defined in connection with Figure 10.
  • a central cut-out portion 162 is arranged between two inner pairs of fingers 154, 155; 156, 157 placed on either side of the central transverse axis A Y
  • Two further, outer cut-out portions 163, 164 are arranged at either end of the opening 4.
  • the main axes A 1 -A 6 of the fingers are all placed at substantially the same angle a in relation to the longitudinal axis A X .
  • the fingers are arranged symmetrically around the central transverse axis A Y only.
  • the main axes of each of the corresponding fingers on either side of the transverse axis A Y will intersect on that axis A Y .
  • the innermost fingers 154, 156 will diverge from each other on either side of the transverse axis A Y , but on the same side of the longitudinal axis A X .
  • This arrangement allows a larger central cut-out 162, which makes the upper tissue more accessible to the user when the first tissue is to be pulled out.
  • the diverging innermost fingers 154, 156 will to a certain extent stretch and smoothen the central part of a tissue held in the presentation position.
  • the top wall includes the opening and the fingers in one piece.
  • the cut line of the slot making up the fingers is arranged directly in the top wall.
  • the box itself, or at least the top wall is made from a plastic material, having projections or fingers cut or perforated in the top wall.
  • a line defining the opening, which would normally control the movement of the fingers, can be embossed directly on the top wall. It is also possible to provide each individual finger with a specific embossing or pattern, in order to give each finger a predetermined flexibility. The stiffness and flexibility of the fingers can also be controlled by the thickness of the material in the top wall.
  • the shape of the slot containing the projections or fingers or the positioning and shape of the embossed opening varied in accordance with the above examples.
  • FIG. 5 This embodiment, wherein a closed opening is cut directly in the top wall, can be used for all examples described above, with the exception of that of Figure 5, which discloses fingers that overlap the edge of the opening.
  • the opening would need to comprise two separate sets of fingers cut in a top wall made up of two halves on opposite sides of a blank for a box.
  • the blank including the opposed halves of the top wall When folded into a box, the blank including the opposed halves of the top wall will be folded along folding lines substantially parallel to the final opening.
  • the two halves of the top wall will eventually be folded around until they reach a position where the cut fingers face each other in a common plane. In this way the fingers can be made longer than what would be possible using a single cut line between opposing fingers.
  • the amount of overlap can be controlled by adjusting the length of the fingers.
  • the embossed line defining the opening can be made at any desired position adjacent or overlapping the base of the fingers.
