Definitions

  • Sheet materials such as facial tissue, are commonly stored and dispensed from cartons.
  • the cartons are constructed so that tissues can be picked out one by one through an opening covered with a dispensing window.
  • the dispensing window comprises a dispensing slit or cut-out portion that may be configured to holds tissues for pop-up type dispensing.
  • the slit must be configured such that when one tissue is removed from the box, the following one is partially pulled out and is held in a substantially up-right position by the slit so that a user may grab and pull it during the next use. This requires appropriate balance between the shape of the slit and material that are used for the window.
  • U.S. Pat. No. 5,316,177 which discloses a pop-up facial tissue carton with a paper window having an elongated opening with two or more slits emanating from its two ends, created a large degree of friction between the dispensed tissue sheet and the paper window. While the high degree of friction prevented fallbacks, it was noisy and caused tearing of the paper window.
  • German Utility model G9108036 also discloses a carton having a paper dispensing window. To reduce the degree of friction between the dispensed sheet and the paper dispensing window, the window is provided with an opening that extends all the way to the carton opening at two or more points. While such designs may reduce the amount of friction, they are susceptible to fallbacks and the window is easily deformed, bent, or torn.
  • the present inventors have now discovered a carton, particularly a carton for storing and dispensing folded tissue sheets in a pop-up fashion, having a paper dispensing window having a dispensing opening having a plurality of cusps and slits.
  • the cusps and slits cooperate with one another to hold the sheet material without tearing of the window or without excessive noise.
  • the carton and dispensing openings have been sized and shaped to permit the paper window to be bent or folded during dispensing without tearing.
  • the present invention provides a tissue carton for storing and dispensing a plurality of tissue sheets, the carton comprising: a carton having at least one carton wall; a carton opening disposed on the at least one carton wall, the opening having a carton opening peripheral edge; a paper window attached to the at least one carton wall and at least partially covering the carton opening; a dispensing opening disposed on the paper window, the opening having a peripheral edge shaped to define a first and a second cusp; and a slit extending radially outward from each of the first and the second cusps.
  • the present invention provides a pop-up tissue dispensing carton comprising: a carton top wall having an elongated carton opening disposed on the carton top wall, a paper window affixed to the top wall and having an elongated opening through which tissues within the carton are withdrawn, the elongated opening having at least two cusps and at least two slits extending therefrom at an acute angle relative to the longitudinal axis of the elongated opening.
  • the present invention provides a dispensing carton containing a stack of interfolded sheets of a paper product comprising: a top wall having a dispensing opening through which the sheets are withdrawn from the carton; two pairs of opposing side walls; a bottom wall; a paper window affixed to at least a portion of the inner surface of the top wall; a dispensing opening having a plurality of cusps and a plurality of slits disposed on the paper window.
  • FIG. 1 is a perspective view of a tissue carton, illustrating a dispensing window according to one embodiment of the present invention

  • FIG. 7 is a top view of dispensing window according to another embodiment of the present invention.
  • FIG. 8 is a top view of dispensing window according to still another embodiment of the present invention.
  • FIG. 9 is a top view of dispensing window according to another embodiment of the present invention.
  • FIG. 10 is a top view of dispensing window according to yet another embodiment of the present invention.
  • carton opening generally refers to an opening formed in one or more walls of a carton.
  • cusp generally refers to a point where two segments meet and the tangents of each of the segments is equal.
  • a cusp may be a sharp corner formed by a pair of converging curvilinear segments where the curve is not differentiable.
  • the term "dispensing opening” generally refers to an opening through which tissues are dispensed such as, for example, an opening formed in a material covering a portion of the carton opening.
  • paper generally refers to a fibrous structure in sheet format. Paper useful in the present invention may be manufactured from a variety of paper-making fibers, such as, for example, natural fibers or synthetic fibers, or any other suitable fibers, and any combination thereof. Papermaking fibers useful in the present invention include cellulosic fibers commonly known as wood pulp fibers. Applicable wood pulps include chemical pulps, such as Kraft, sulfite, and sulfate pulps, as well as mechanical pulps including, for example, groundwood, thermomechanical pulp and chemically modified thermomechanical pulp. As used herein the term “panel” generally refers to a portion of a dispensing window within a carton opening that is entirely separated from another portion of the dispensing window.
  • the separation of a dispensing window within a carton opening into first and second panels may be achieved by a slit extending from the dispensing opening to the carton opening peripheral edge.
  • a non-limiting example of a panel is illustrated in FIG. 1, where slits separating the window 40 into four panels 62, 64, 66, 68. Each of the four panels 62, 64, 66, 68 are entirely separated from one another by a slit 48.
  • slit generally refers to a cut where no material is removed.
  • a tissue carton of the present invention may be provided with a window having one or more slits disposed thereon and the tissue is fitted through a slit which frictionally retains the tissue unless it is manually moved through the slit.
  • tissue generally refers to any individual sheet product, such as facial tissue, dry or moistened wipes, for example household or industrial wipes, soap or fabric softening sheets, or the like.
  • basis weight of sheet products to be dispensed by the cartons of the present invention is less than about 80 grams per square meter (gsm), in some embodiments less than about 60 gsm, and in some embodiments, between about 10 to about 60 gsm.
  • window generally refers to a component of the carton covering at least a portion of the carton opening and generally having a dispensing opening disposed thereon for dispensing a tissue there-through.
  • a pop-up tissue dispenser 20 also referred to herein simply as a carton, according to one embodiment of the present invention is shown for purposes of illustration.
  • a clip of prefolded interfolded tissues is disposed within the carton.
  • the carton of the present invention is particularly well suited for dispensing folded tissue sheets, such as folded facial tissue sheets, the invention is not so limited.
  • the invention may also be utilized to dispense other types of folded sheet products.
  • tissue is not intended to be limited to facial tissues but is used herein to include any individual sheet product, such as dry or moistened wipes, for example household or industrial wipes, soap or fabric softening sheets, or the like.
  • the folded edge 51 of the upper most tissue sheet 50 is visible through the dispensing opening 42 and presented for dispensing by a user.
  • the stack of tissues may be interfolded, prefolded interfolded, or non-interfolded.
  • prefolded interfolded or "interfolded” tissues means that the tissues are folded and interleaved with neighboring tissues immediately above and/or below in the clip of tissues.
  • the tissues can be interleaved by any suitable means, including the use of an interfolder as employed in the papermaking arts. If an interfolder is used, consecutive tissues may be attached to each other at perforation lines. In such cases, the unperforated segments of the perforation lines should be sufficiently weak to permit the consecutive tissues to separate from each other upon removal from the carton. This can be controlled by the degree of perforation of the tissue sheet.
  • Tissues that may be employed in a non-interfolded clip which are not interleaved with neighboring tissues are releasably attached to neighboring tissues so that upon dispensing one tissue, the next adjacent tissue is ready for dispensing.
  • Particularly preferred folding patterns include interfolding patterns that provide somewhat less friction, which tend to avoid tearing of the tissue when extracted from the container.
  • the carton 20 is illustrated as a rectangular parallelepiped comprising a top wall 26, and opposite bottom wall (not illustrated in FIG. 1), and four sidewalls extending between the top 26 and bottom walls.
  • the sidewalls that are fully visible in FIG. 1 have been given reference numerals 22 and 24.
  • the carton of FIG. 1 is rectangular parallelepiped, the invention is not so limited, and the carton may be constructed in a variety of sizes and shapes as are well known in the art.
  • the carton includes a single cylindrical-shaped sidewall extending between the top and bottom walls (not shown).
  • any of the sidewalls such as sidewalls 22, 24 may be constructed of one or more panels that are bonded together by adhesives, thermal bonds, or other suitable means.
  • the carton may be constructed from any rigid materials, for example, cardboard, carton stock, paper board, polypropylene, polyethylene, polystyrene, ABS plastic, plastic, metal, wood, and glass amongst other suitable alternatives.
  • the top wall 26 of the carton 20 defines a carton opening 30 having a peripheral edge 32 in the form of an aperture through which tissues may be individually removed from the carton.
  • the carton of FIG. 1 comprises, a carton opening disposed on the top wall of the carton, the invention is not so limited.
  • the shape of the carton opening may vary, however, in certain preferred embodiments the opening is elliptical and being of a size to permit comfortable entry of the finger(s) of a user for access to the sheets in the receptacle but occupying less than the entire area of said top wall whereby at least the major portion of the periphery of said top wall is intact.
  • the carton opening is a longitudinally elongated ellipse having its major axis oriented generally in the direction of the longer dimension of the folded sheet disposed within the carton.
  • the carton 20 has the shape of a rectangle parallelepiped
  • the carton opening 30 has the shape of a longitudinally elongated ellipse.
