Definitions
- Rolls products are sometimes packaged and shipped in bundles comprising a plurality of rolls.
- the bundled packages often have two or more rolls stacked in a side-by- side fashion with another two or more rolls.
- the rolled products are arranged in a vertical, stacked configuration (i.e., a longitudinal axis of each core of each roll is generally vertical).
- the group of vertically oriented rolls is then processed through a bundler which applies an overwrap.
- the overwrap is sealed with a gusset seal on the leading and trailing sides of the group of rolled products. Arranging rolls in this manner allows for stacking of packages and the arrangement of stacks on pallets for shipping and display.
- gusset seals offer many advantages on bundled packages of tissue products, such as improved sealing and handling, they often require folds and creases of multiple layers of the overwrap that may result in poor visual appearance on the outer perimeter of the bundle. Further, the fold and creases may block visual aspects of the individually wrapped packages contained therein. The folds and creases may also cover up or distort valuable branding information on the individually wrapped packages. Furthermore, the folds and creases can inhibit the full use of all the package face areas for advertising or branding.
- overwrapped bundles have gussets and creases that can negatively affect the visual aesthetics of the package and limit the surface area of the package that may be printed, but the gussets and seals are typically not resalable and must be permanently ruptured to access and dispense the rolled tissue products. Further, the overwrap is typically flexible and becomes deformed after dispensing of a product, resulting in a package that cannot be stacked and has poor aesthetics.
- the present invention solves many of the problems of prior art overwrapped bundles of tissue products.
- the present package is formed from a semi-rigid film, that when sealed and folded provides the package with distinct, planar walls that provide a clear view of the package contents and that are amenable to printing with brand indicia.
- the semi-rigid film and package configuration provides a package that can be provided with a resealable flap that provides easy and convenient repeated access to the package contents.
- the package maintains its form and integrity, which is not only visually pleasing, but also permits the package to be stacked even after it has been opened and rolled products have been dispensed.
- the present invention provides a package for tissue products comprising a bottom wall, a top wall, opposite sidewalls, and opposite end walls, wherein the package includes a flap which is movable between a closed position and an open position to facilitate access to the package interior, and which may comprise portions of the top wall and an adjoining sidewall of the package.
- the package is preferably made of a semi-rigid plastic material that is bendable so as to permit the flap to bend as it is moved between a closed and an open position, but which allows the package to retain its shape even after all of the products have been dispensed.
- the invention provides a package that does not depend upon a separate container, such as a frame, carrier, carton, or the like, to retain and protect the package contents and provide structural integrity to the package.
- the package may be configured so that when the flap is in an open position, the tissue product is accessible from the side as well as the top, which permits a user to grasp a larger portion of the product, particularly when the package is full, or near full and a portion of the product is retained by a portion of the package beyond the opening. Further, permitting access from two faces of the package, such as from the top wall and an adjoining sidewall, permits the product to be removed without undue distortion.
- the present invention provides a unitary package formed from a single piece of semi-rigid plastic film having bending stiffness from about 20.0 to about 60.0 mgf and more preferably from about 25.0 to about 50.0 mgf.
- the single piece of semi-rigid plastic film is folded and sealed to form the package.
- the package contents are accessed and removed from the package by a flap that is integrally formed with the package top wall by forming a line of weakness in the single piece of semi-rigid plastic film used to form the package.
- the present invention provides a package for tissue products comprising a bottom wall, a top wall with an opening disposed thereon, opposite sidewalls, and opposite end walls, wherein the package includes a flap covering the opening.
- the flap may be formed entirely of a separate piece of material and be separable from the package or may comprise portions of the top wall to prevent the flap from being completely removed from the package.
- the flap may be peelably and resealably sealed along one or more edges.
- An opening is provided in the package walls underlying the flap.
- the opening underlying the flap is preferably sized so as to permit the tissue products to be dispensed without deforming.
- the opening may be formed by cutting the film used to form the package or may be made by providing a line of weakness in the top wall beneath the flap and the flap may be adhered to the top wall so that as the flap is pulled open, portions of the top wall are pulled away with the flap.
- the line of weakness may extend about the entire periphery of the opening or may extend only about a portion of the opening, so that the portions of the top wall and sidewall which are pulled away when the flap is opened are not completely disconnected from the adjoining package material, but remain connected thereto.
- the flap may be provided with a label that is peeled away from the package material on one side of the line of weakness. As the label is peeled away the package material is parted at the line of weakness to provide the opening.
- the line of weakness may extend along the upper edge of one of the sidewalls where it meets the top wall and then along the top wall so that an opening is formed along two faces of the package.

- the present invention generally provides a semi-rigid package for storing and dispensing tissue products and more particularly rolled tissue products, such as paper towels, toilet tissue, disposable shop towels, and wipes, for example.
- tissue products such as paper towels, toilet tissue, disposable shop towels, and wipes
- the present package is formed from a semi-rigid material that provides the package with structural integrity, even when the products have been dispensed. Further, the present package provides a flap that allows easy access to the contents of the package and protects the products when the package is not in use.
- the invention is generally embodied in a package for tissue products comprising a bottom wall, a top wall, opposite sidewalls and opposite end walls.
- the package is preferably formed from a web of semi-rigid plastic material, more particularly a plastic material having a bending stiffness greater than about 20.0 and more preferably greater than about 25.0 and still more preferably greater than about 30.0 mgf, such as from about 20.0 to about 60.0 mgf and more preferably from about 25.0 to about 50.0 mgf.
- bending resistance means the resistance measured in the machine direction (MD) of the material via a Gurley resistance test as set forth in TAPPI Standard Test T 543 om-1 1 (Bending Resistance of Paper (Gurley type tester)), and reported in milligrams of force.
- a suitable testing apparatus is a Gurley Digital Resistance Tester, model 4171 -D manufactured by Teledyne Gurley, a business having offices in Troy, N.Y., U.S.A.
- a specimen is cut from a wipes dispenser and tested in accordance with the above-referenced TAPPI test. Although the length and width dimensions of the specimen that is cut and tested may be adjusted to accommodate the size or nature of a sample as noted in section 6 of the procedure, the force measurement for any given sample size is normalized to correspond to a 50.8 mm (2 in) by 63.5 mm (2.5 in) sample size, as set forth in TAPPI Standard Test 543 om-1 1 , including the use of the correct specified conversion factor depending on the test parameters used.
- the table below sets forth the bending stiffness, as measured in the MD, for various materials, including those useful in the present invention, and also provides the specimen size, weight and mounting position for each material tested in accordance with TAPPI Standard Test 543 om-1 1.
- the semi-rigid material allows the package to retain its shape even after all of the products have been dispensed.
- the invention provides a package that does not depend upon a separate container, such as a frame, carrier, carton, or the like, to retain and protect the package contents and provide structural integrity to the package.
- a container such as a frame, carrier, carton, or the like
- the present package contents such as rolls of tissue, are in direct contact with the walls of the package which reduces packaging cost and complexity and permits for easy dispensing of the product.
- the thickness of the semi-rigid film may vary. Generally, stiffness is a function of both the film's modulus and its thickness. Thus, a thinner film may be used so long as the film's modulus is sufficiently high to provide a stiffness greater than at least about 20.0 mgf, from about 20.0 to about 50.0 mgf and more preferably from about 25.0 to about 40.0 mgf. In certain preferred embodiments the film should be thin enough so it can be easily folded and manipulated to form the instant package, yet thick enough to provide the necessary structural integrity and barrier properties to protect and preserve the rolled tissue products contained therein.
- the film has a thickness of at least about 50 microns, and more preferably at least about 60 microns and still more preferably at least about 75 microns, such as from about 50 to about 200 microns and still more preferably from about 70 to about 100 microns.
- Caliper is measured according to Tappi Test Method T 411 om-15 and typically has units of mils or microns.
- the modulus of the film is preferably sufficiently high so as to provide the film with sufficient stiffness to resist collapse of the package when the contents are dispensed, such as a bending stiffness greater than about 20.0 mgf and more preferably greater than about 25.0 mgf and still more preferably greater than about 30.0 mgf, such as from about 20.0 to about 60.0 mgf and more preferably from about 25.0 to about 50.0 mgf.
- Films having the foregoing stiffness are desirable not only for their ability to resist collapse after products have been dispensed from the package, but are readily bendable and sufficiently flexible to be folded and shaped into a package without additional processing steps such as scoring, cutting and the like.
- the packaging film may have a modulus greater than about 350 MPa and more preferably greater than about 450 MPa, such as from about 350 to about 1250 MPa and more preferably from about 450 MPa to about 750 MPa.
- the film has a thickness from 70 to about 100 microns and a modulus from about 450 to about 750 MPa.
- the secant modulus is the ratio of stress to corresponding strain at a strain of 1 .0 percent, that is, the slope of the straight line that joins the origin and a point on the actual stress- strain curve at a strain of 1.0 percent. Secant modulus is measured according to ASTM D790 and has units of megapascals (MPa, pounds per square inch).
- the film may comprise one or more plastic resins such as polyethylene (LDPE, LLPE, VLDPE, HDPE, MDPE), polypropylene, polyethylene terephalate, nylon, other vinyl polymers and copolymers such as those made from vinyl acetate, vinyl alcohol, vinyl chloride, and so forth.
- the film may comprise combinations of two or more of the foregoing synthetic resins. For example, blends of two or more resins can be used to form a single layer film, or even a multiple layer film.
- the film is a multi-layer film composed of two or more layers of the foregoing resins bonded together by any known technique such as co-extrusion ("coex”), laminating with or without an adhesive, coating, or the like.
- the film may comprise coextruded polyethylene/polypropylene laminated to polyethylene terephalate (PET) or PET laminated to LDPE (low density polyethylene).
- PET polyethylene terephalate
- LDPE low density polyethylene
- the film may comprise coextruded polyethylene (PE) and oriented polyethylene terephthalate (oPET).
- the film is preferably amenable to sealing so as to form one or more sealed edges when folded into a package.
- the film may be heat sealable.
- the film may comprise a thermoplastic resin that is rendered tacky when heated allowing two portions of the film brought into facing arrangement with one another to be bonded.
- portions of the film brought into facing relation with one another may be bonded using an adhesive bonding layer or coating.
- the preferred adhesive coatings are those based upon thermoplastic resins whereby the coating is non-tacky at room temperature but becomes tacky and adhesive when heated, such as a coating of polyethylene resin or acrylic resin.
- the package film may comprise a laminated film having one or more layers which respond to heat and pressure by forming a seal of variable strength, with the strength of the seal depending in part on the magnitude of the heat transfer and pressure applied.
- a peelable seal region may be provided adjacent a permanent seal region by varying the heat transfer, pressure and width of application between the two regions.
- the package 10 comprises a unitary piece of film 17 folded to form a top wall 12, a bottom wall 14, a pair of sidewalls 16, and a pair of end walls 18.
- the package preferably contains a tissue product comprising a plurality of rolled tissue products, such as rolls of bath tissue 30 disposed in the interior of the package.
- the film may be folded in any number of different configurations to form a four-sided package.
- the package may be manufactured by folding the film in a horizontal wrapping operation by continuously wrapping a web of film about the rolled tissue products with marginal longitudinal opposite edges of the web brought together to form a longitudinal seal beneath the product, and with transverse end seals formed at the ends of the package to define end walls. In other embodiments, such as that illustrated in FIGS.
- a single unitary piece of film 17 may be folded and sealed to form a package 10 having a pair of opposed transverse edge seals 13, 15 and a longitudinal seal (not illustrated in FIG. 1) disposed on the bottom wall 14.
- the seals may be either heat seals or cold seals and may be either permanent seals or resealable seals.
- all of the edges, the transverse edge seals and the longitudinal bottom seal are permanently heat sealed. While the embodiment illustrated in FIGS.
- the film may be orientated and wrapped about the package contents such that the opposed sealed edges are oriented in the longitudinal direction of the package and the bottom seal is oriented in the transverse direction of the package.
- the top wall 12 comprises a flap 21 that may be separated from the top wall 12 to provide access to the rolled tissue products 30 in the package.
- the flap 21 is defined by a line of weakness 19 disposed on the top wall 12.
- the line of weakness may be produced using methods including but not limited to scoring, perforating, chemical treatment, preferably laser scoring, laser perforation, mechanical scoring, mechanical perforation, embossing methods, or combinations thereof.
- the line of weakness 19 forming the flap 21 extends along only a portion of its perimeter, such as three sides, leaving the fourth side attached to the top wall 12.
- the attached fourth side may form a living hinge which allows the flap 21 to be moved between a closed and open position.
- the flap may be formed entirely of a separate piece of material and be separable from the package.
- the flap may be peelably and resealably sealed along one or more edges.
- An opening is provided in the package walls underlying the flap.
- the opening underlying the flap is preferably sized so as to permit the tissue products to be dispensed without deforming.
- the opening may be formed by cutting the film used to form the package or may be made by providing a line of weakness in the top wall beneath the flap and the flap may be adhered to the top wall so that as the flap is pulled open, portions of the top wall are pulled away with the flap.
- the line of weakness may extend about the entire periphery of the opening or may extend only about a portion of the opening, so that the only a portion of the top wall is pulled away when the flap is opened. In this manner the flap is not completely disconnected from the adjoining top wall, but remains connected thereto.
- the web is preferably pre-cut with a die-cut perforation or otherwise provided with a line of weakness corresponding to the desired shape of the opening.
- the flap may be applied as a separate piece to the web after the line of weakness defining the opening has been disposed on the web.
- the flap is preferably a label having adhesive covering one side thereof. The label is applied to the web to cover the die-cut perforation or other line of weakness. As the web advances, the label is folded with the underlying substrate, and remains in position.
- flap 21 when flap 21 is pulled back from the top wall 12, it forms a dispensing opening through which the rolled tissue products 30 may be dispensed. A portion of flap 21 remains attached to the top wall 12 along one of its edges.
- the size of the opening 19 and hence the size of flap 21 is at least around 30 percent of the surface area of film 17 and advantageously at least 50 percent of the surface area of film 17 so as to more easily gain access to the rolled tissue products contained within container 10.
- the flap may have a line of weakness disposed completely around its perimeter on all sides so as to be completely separable from the film when removed by the user to form the dispensing opening.
- the line of weakness it is believed that it may be more desirable to have the line of weakness extend about only a portion of the periphery of the opening, so that the package material within the line of weakness remains connected to adjacent package material along one edge of the flap. This may eliminate the need for a permanent seal to be formed at this location, in that the strength of the package material remaining intact will prevent the flap from being entirely removed from the underlying package material.
- the line of weakness 19 illustrated in FIGS. 1-3 is not a closed curve extending about the entire periphery of the opening.
- a sealing label 20 may be affixed to the flap 21 to seal the flap in a closed position when the package 10 is not in use.
- the sealing label 20 is permanently affixed to the flap 21 using an appropriate first adhesive and resealably attached to the top wall 12 using a second adhesive.
- the sealing label 20 covers a portion of the top wall 12, which generally defines a sealing area 27.
- the sealing area 27 terminates prior to any side 16, 18 of the package 10.
- the sealing area 27 does not extend to any of the sides of the package and the package opening is entirely disposed on the top wall 12 of the package 10.
- Opening of the package may be facilitated by providing the sealing label 20 with a tab 22.
- the tab 22 extends from a portion of the sealing label 20 and is preferably not attached to the top wall 12, but rather hangs free from the package so as to be readily grasped by a user. In this manner the tab 22 can be grasped by a user's fingers and thumb and pulled to initiate removal of the label 20 and subsequently the flap 21 . Further, the tab 22 may facilitate closing of the container, providing an adhesive free surface for the user to grasp and position to the label 20 for proper sealing and securing of the flap 21.
- the size of tab and its shape may be optimized for functionality. For example, in certain embodiments the tab is semicircular and has a surface area from about 1 to about 10 percent, and more preferably from about 2 to about 5 percent, total surface area of sealing label.
- the sealing label 20 may be removably adhered to the top wall 12 by applying an adhesive to the underside thereof. The sealing label 20 may then be brought in contact with the top 12 to seal the package 10.
- adhesive provides a removable seal between the sealing label 20 and the top 12.
- adhesive is preferably not applied to the tab.
- a deadening agent either a chemical or a layer of material, is applied to the top wall to prevent the tab portion from adhering to the top of the package.
- FIGS. 4 and 5 illustrate a second embodiment of the invention comprising a package 10 which has a top wall 12, a bottom wall (not illustrated), a pair of sidewalls 16 and a pair of end walls 18.
- the package contains a plurality of rolled tissue products 30.
- the end walls comprise extensions of the top, bottom and sidewalls which are brought together at a transverse end seal 27 on each end wall 18 with extensions 29 of the sidewalls 16 being folded inward at the ends of the package 10.
- the pair of sidewalls 16 are separated from the bottom and top walls a pair of longitudinal edge seals 23, 25. In this manner the side and top walls of the back are substantially planar and well suited for receiving product indicia. Further, the edge seals 23, 25 may further enhance the rigidity of the package 10 to further facilitate its retention of shape once its contents have been dispensed.
- a single opening is formed in adjacent portions of the top wall 12 and one of the end walls 18.
- the opening may be covered by a flap 21 having a sealing label 20 extending about a portion of its periphery.
- a tab 22 is left unsealed to facilitate initiation of opening of the package.
- the width of the flap 21 is approximately equal to the width of the opening (OW, illustrated in FIG. 3).
- the shape of the flap 21 and the opening are substantially similar and preferably the opening has an opening width (OW) about 90 to about 1 10 percent and more preferably from about 95 to about 105 percent of the width of the rolled tissue products (RW).
- the opening and flap be of similar shape and dimensions, the invention is not so limited.
- an opening is provided in the package walls underlying the flap where the opening has a width less than the width of the flap.
- the opening underlying the flap is preferably sized so as to permit the tissue products to be dispensed without deforming and the flap is sized to form a seal between the flap and top wall along a portion of the opening perimeter.
- the opening may be formed by cutting the film used to form the package or may be made by providing a line of weakness in the top wall beneath the flap and the flap may be adhered to the top wall so that as the flap is pulled open, portions of the top wall are pulled away with the flap.
- the line of weakness may extend about the entire periphery of the opening or may extend only about a portion of the opening, so that the portions of the top wall and sidewall which are pulled away when the flap is opened are not completely disconnected from the adjoining package material, but remain connected thereto.
- the package comprises a top wall 12, a bottom wall 14, a pair of sidewalls 16 and a pair of end walls 18.
- the pair of end walls 18 comprises a folded and sealed closure which will be described in further detail below.
- the top wall 12, bottom wall 14, sidewalls 16 and end walls 18 are all integral portions of a single sheet semi-rigid film material 17.
- the sidewalls 16 comprise permanent longitudinal side seams 40, 42, 44, 46.
- One of the longitudinal side seam 44 is formed by bringing the marginal edges 41 , 43 of the sheet material 17 into sealing engagement with each other.
- the other longitudinal side seams 40, 42 and 46 are formed by folding the sheet material 17 into facing arrangement with itself and sealing.
- the longitudinal side seams 40, 42, 44, 46 are preferably permanently secured to one another via any conventional sealing technique known in the art, such as heat sealing or welding.
- the end walls 18 of the package are also preferably sealed to close the package. In certain embodiments the end walls are also sealed closed, for example, along permanent transverse end seal 29.
- the package of the embodiment illustrated in FIGS. 6 and 7 may be manufactured by folding a single sheet of semi-rigid material, such as the sheet illustrated in FIG. 8.
- the sheet may have a rectangular shape with parallel edges 41 , 43 that are brought together and sealed to form a permanent edge seal (illustrated as longitudinal seal 44 in FIGS. 6 and 7) and form a tube like structure (not illustrated).
- the width of the permanent edge seal may vary, however, in certain embodiments the width may be from about 2 to about 10 mm. Additional permanent seals are then formed to transform the tube into a parallelepiped package with the permanent seal lines 40, 42, 44, 46 forming four substantially square corners of package 10.
